Description

[0001] Equipment of a multi-nozzle device of an agricultural

[0002] Distribution machine and multi-nozzle device

[0003] In short, the invention relates to devices of a multi-nozzle device of an agricultural spreading machine and a multi-nozzle device of an agricultural spreading machine.

[0004] More specifically, the invention relates to a multi-nozzle device with an inlet device for receiving a liquid, a conduit device for conveying and / or guiding a liquid to an outlet device of the multi-nozzle device, a control device for controlling a flow direction and / or for controlling the flow of a liquid to an outlet device of the multi-nozzle device, an outlet device for dispensing a liquid and / or a selection device for selecting and / or determining the dispensing of a liquid from an outlet device of the multi-nozzle device.

[0005] Prior art EP 3 485 728 B1 discloses an agricultural spreading machine with a distribution boom comprising at least one nozzle assembly. Each nozzle assembly is connected to a first and a second valve, and the nozzle assembly comprises multiple first and second nozzles. For example, a first nozzle is connected to the first valve and a second nozzle to the second valve, with the first and second nozzles of the nozzle assembly being arranged in a single nozzle body on the distribution boom, spatially adjacent to each other. Furthermore, the second nozzle is connected to the first valve by means of a directional control valve.

[0006] Thus, the directional control valve allows a first liquid to be dispensed from both the first and the second nozzle. Furthermore, the directional control valve also allows a second liquid to be dispensed from both the first and the second nozzle. Additionally, in this configuration, the directional control valve makes it possible for a first liquid to be dispensed from the first nozzle and a second liquid from the second nozzle.

[0007] However, EP 3 485 728 B1 reveals that the directional control valve must be hydraulically or pneumatically operated. This solution involves increased costs, for example, for hydraulic or pneumatic actuators, hoses, and connectors. All of the aforementioned parts must also be checked at regular maintenance intervals to ensure the correct functioning of the hydraulic or pneumatic system. This also incurs additional costs.

[0008] Against this background, the object of the present invention is to provide a multi-nozzle device for an agricultural spreading machine, the individual parts of which can be manufactured cost-effectively and / or which can also be manufactured cost-effectively as an assembly and / or which has longer maintenance intervals.

[0009] Furthermore, it is an object of the present invention to provide individual components of a multi-nozzle device that are cost-effective to manufacture and / or that can be cost-effectively assembled into a module and / or that have longer maintenance intervals. It is also an object of the present invention to provide individual components of a multi-nozzle device and / or a multi-nozzle device of an agricultural spreading machine, by means of which one or more liquids can be applied to a cultivated area and / or to plants in a simple and even more flexible manner.

[0010] These problems are solved by the features of the independent patent claims. Further advantageous developments are the subject of the dependent claims.

[0011] In the context of the invention, the term "liquid" or "liquids" preferably refers to a spraying agent intended and / or suitable for agricultural applications. Preferably, the liquid or spraying agent may be a plant protection product, fertilizer, herbicide and / or pesticide, or the like. Furthermore, preferably, the liquid or spraying agent may also be referred to as a spray mixture. Alternatively or additionally, the liquid or spraying agent may comprise one or more solid and / or liquid active ingredients, which are particularly preferably mixed with and / or can be mixed into a liquid or base mixture, such as, for example, essentially water. Furthermore, alternatively or additionally, it may also be provided that several different liquids or...Sprays are intended for application, for example a first and second liquid which differ in the composition and / or concentration of at least one active ingredient.

[0012] A first aspect of the present invention comprises an inlet device of a multi-nozzle device of an agricultural distribution machine, such as an agricultural field sprayer.

[0013] The inlet device includes a first receiving unit for receiving a first liquid. This first receiving unit is connectable to a first liquid line of an agricultural distribution machine and has an inlet for a first liquid and at least one outlet for a first liquid. The first receiving unit may have a first and a second outlet for a first liquid. The two outlets, or the first and second outlets, may be oriented in opposite directions, allowing a first liquid to be directed, conveyed, or transported in two different directions. Furthermore, the two outlets, or the first and second outlets, may be oriented or aligned in a second plane, for example, horizontally.

[0014] Furthermore, it is also conceivable that the first and second outputs of the first recording unit could alternatively or additionally be arranged differently relative to each other, e.g., side by side and / or offset from each other. Furthermore, the first recording unit could alternatively or additionally comprise more than two outputs, for example, three or four, which could be arranged at least partially concentrically, coaxially, and / or side by side.

[0015] Furthermore, the inlet device has a second receiving unit for receiving a second liquid. This second receiving unit can be connected to a second liquid line of an agricultural distribution machine and has an inlet for a second liquid and at least one outlet for a first and / or second liquid. The second receiving unit also has a first outlet for a second liquid and a second outlet for a first liquid to convey two different liquid flows or liquids.

[0016] Furthermore, the second output of the second receiving unit is fluid-connected to the input of the first receiving unit. In this way, for example, a first liquid can be passed from both the first and second receiving units. It is also possible for only a second liquid to be passed from the second receiving unit.

[0017] In light of the above considerations, a simple inlet device can be created that is cost-effective to manufacture and allows for the easy transfer of liquid flows from different inlets to different outlets. Furthermore, the aforementioned design of the inlet device allows for two receiving units to be formed from a single component. Thus, the inlet device can be manufactured as a single unit, simplifying production. Moreover, the described inlet device design allows for the highly flexible application of one or more liquids to a surface and / or to plants.

[0018] Furthermore, the first and / or second receiving unit can be configured to convey a first and / or second liquid simultaneously or with a time delay, and / or in unlimited and / or any quantity. Thus, the first and / or second receiving unit has no limitation that artificially restricts or limits the amount of liquid flowing through the receiving unit. In short, the receiving unit cannot have any limitations or controls to limit a liquid flow or, similar to a train switch, to direct it entirely in one direction or another. Rather, the first and second receiving units can always be supplied with liquid without controlling the liquid flow. The only limitation is due to the diameter of the connecting pipes.

[0019] The first and second outlets of the second receiving unit can be arranged coaxially and / or spaced apart to allow two liquid flows, or a first and second liquid, to be routed separately. As a result, a first and second liquid can be routed from a single point or position. Thus, only one connection point is required for two liquids.

[0020] Furthermore, the first and second outlets of the second receiving unit can be arranged concentrically to allow two separate fluid flows, one for a first liquid and one for a second liquid. Consequently, a first and second liquid can be routed from a single point or position. Thus, only one connection point is necessary for both liquids.

[0021] Furthermore, it is also conceivable that the first and second outputs of the second receiving unit could alternatively or additionally be arranged differently relative to each other, e.g., side by side and / or offset from each other. The second receiving unit could also alternatively or additionally comprise more than two outputs, for example, three or four, which could be arranged at least partially concentrically, coaxially, and / or side by side. Furthermore, the first output of the second receiving unit could surround, frame, encompass, or orbit the second output of the second receiving unit. It is also possible that the first output of the second receiving unit has a cross-sectional shape in the form of a hollow cylindrical recess. Additionally, the second output of the second receiving unit could have a cross-sectional shape in the form of a cylindrical recess.The first and second outlets of the second receiving unit can also be arranged and configured relative to each other in such a way that both outlets feature a pipe-within-a-pipe arrangement. This allows a first and second liquid to be conveyed at a common point or position. Consequently, only one connection or connection point is required for both liquids.

[0022] In addition, it can be provided that, for example, liquid can flow in at the inlet and liquid can flow out at at least one outlet.

[0023] The fluid connection between the inlet and at least one outlet can be non-shuttable, uninterruptible, or non-interruptible.

[0024] Furthermore, the fluid connection between the inlet of the first receiving unit and a second outlet of the second receiving unit can be either non-shuttable, uninterruptible, or uninterruptible. Additionally, the fluid connection between the inlet of the first receiving unit and at least one outlet of the first receiving unit can be either non-shuttable, uninterruptible, or uninterruptible.

[0025] Furthermore, the fluid connection between the inlet of the second receiving unit and at least one outlet of the second receiving unit can be non-lockable, uninterruptible, or non-interruptible.

[0026] Therefore, the flow of an incoming liquid cannot be interrupted or stopped by the inlet device. In short, the inlet device cannot have any limitations or controls to limit the liquid flow or, like a train switch, to direct it entirely in one direction or another. Rather, the first and second receiving units can always be supplied with liquid without controlling the flow. The only limitation is due to the diameter of the connecting pipes.

[0027] Furthermore, the first receiving unit can have an inlet line for a first liquid. This inlet line can be oriented or aligned in a first plane, for example, vertically. The first plane and a second plane can be aligned or oriented at an angle to each other, for example, 90 degrees.

[0028] The input of the first receiving unit can be located at one end of the input line. A first output of the first receiving unit or a branch of the first receiving unit can be located at the other end of the input line.

[0029] Furthermore, the input line of the first recording unit can be hollow cylindrical in shape.

[0030] Furthermore, the second receiving unit can have an inlet line for a second liquid. The inlet line can be oriented or aligned in a first plane, for example, vertically. The first plane and a second plane can be aligned or oriented at an angle to each other, for example, 90 degrees. The inlet of the second receiving unit can be located at one end of the first inlet line. At least one outlet of the second receiving unit can be located at the other end of the inlet line.

[0031] The inlet line of the second receiving unit can be partially hollow cylindrical and / or partially form part of a concentric double tube or part of a tube-in-tube arrangement. Thus, the inner tube and the outer tube surrounding the inner tube can convey a first and second liquid, respectively.

[0032] Furthermore, the first receiving unit can have a fork to divide a fluid flow, for example, of a first fluid, that can flow through an inlet line of the first receiving unit. The fork can be arranged between a first and second end of the inlet line of the first receiving unit and / or between the inlet and at least one first outlet of the first receiving unit. The fork can also be configured to divert a fluid flow, for example, of a first fluid, that can flow into an inlet line of the first receiving unit, at least partially into a connecting line of the receiving unit. Thus, the fork can divide a fluid flow of a first and / or second fluid, but it cannot restrict or stop it.

[0033] Furthermore, the inlet device can include a connecting line for a first liquid to direct a liquid flow from the first receiving unit towards the second receiving unit. The connecting line of the inlet device can be straight, at least in sections. The connecting line can also be oriented or aligned in a second plane, for example, horizontally. The first and second planes can be aligned or oriented at an angle to each other, for example, 90 degrees. This allows for the deflection of a liquid.

[0034] The connecting line can begin at or within an inlet line of the first receiving unit and end at or within an inlet line of the second receiving unit. Consequently, a liquid can flow from the first to the second receiving unit. This allows for highly flexible application of one or more liquids across a usable area and / or to plants.

[0035] The connecting line can start between a first and second end of the input line of the first recording unit and / or between the input and two outputs of the second recording unit or end at a first and / or second output of the second recording unit.

[0036] The connecting pipe can be hollow and cylindrical. This allows a liquid to flow through the connecting pipe with low resistance.

[0037] The ends of the connecting line and an inlet line of the second receiving unit can be arranged concentrically and / or coaxially, for example, at a first and second outlet of the second receiving unit, and / or form a first and second outlet of the second receiving unit to convey two fluid flows and / or to convey a first and second fluid separately. A portion of the connecting line can extend into the inlet line of the second receiving unit. Thus, the connecting line and the inlet line can partially form a concentric double pipe or a pipe-in-pipe arrangement. The connecting line can also, at least partially, form a branch of the first receiving unit with its first end. This also allows fluid to be drawn from the inlet line or from the first receiving unit.

[0038] Furthermore, the connecting line can form a second output of the second receiving unit at its second end. Liquid, for example, can be dispensed here.

[0039] Furthermore, the inlet device may have a connecting line for a first liquid to direct a liquid flow of a first liquid from the first receiving unit towards the second receiving unit.

[0040] The connecting line can form a branch at its first end of the first receiving unit. This allows the connecting line to receive fluid from the first receiving unit.

[0041] Furthermore, the connecting line can form a second output of the second receiving unit at its second end. Liquid, for example, can be dispensed here.

[0042] Furthermore, several such connecting lines, for example two, three or more, may be provided.

[0043] The connecting line or lines between the first and second recording unit can also be arranged and / or designed and / or arranged between different recording units.

[0044] Furthermore, the first receiving unit can have an inlet line for a first liquid. The inlet line can be oriented or aligned in a first plane, for example, vertically. The first plane and a second plane can be aligned or oriented at an angle to each other, for example, 90 degrees. Thus, a deflection of a liquid is conceivable.

[0045] The input of the first recording unit can be located at one end of the input line.

[0046] At the second end of the inlet line, a first outlet and / or a branch of the first receiving unit can be arranged. Thus, a fluid flow can be split at the second end by the branch.

[0047] Furthermore, the first receiving unit can have a fork to divide a fluid flow, for example a first fluid, that can flow through an inlet line of the first receiving unit.

[0048] The bifurcation can be designed to divide a fluid flow, for example a first fluid, which can flow into an inlet line of the first receiving unit, for example into equal parts.

[0049] Furthermore, the branch can be located between the first and second ends of the inlet line of the first receiving unit and / or between the inlet and two first outlets of the first receiving unit. Thus, a fluid flow, for example of a first liquid, can be divided or split.

[0050] The input of the first receiving unit can be located at one end of the input line. A first and a second output of the first receiving unit, or a branch of the first receiving unit, can be located at the second end of the input line.

[0051] Furthermore, the first receiving unit can have an inlet line for a first liquid. The inlet line can be hollow cylindrical, for example, upstream of a branch of the first receiving unit. Such a design results in low hydraulic resistance.

[0052] In addition, the input line can be designed in the form of a cylindrical recess, for example downstream of a fork in the first receiving unit.

[0053] A line assembly for a multi-nozzle device can be connected to the first and / or second output of the first receiving unit.

[0054] Alternatively or additionally, the first receiving unit can be designed as a single piece with a piping system for a multi-nozzle device. Thus, a multi-part or single-piece design of the receiving unit is possible, or it is conceivable to combine the receiving unit with a piping system for the multi-nozzle device.

[0055] Furthermore, alternatively or additionally, the first receiving unit can be formed in one piece with a piping assembly of a multi-nozzle device. In summary, it can therefore be stated that the inlet device and a piping assembly of a multi-nozzle device can together form a single part or two separate parts.

[0056] Furthermore, the first outlet of the first receiving unit can be fluid-connected to at least one transfer line, e.g., a first transfer line, a piping device, or a multi-nozzle device. In this way, it is possible to transfer a fluid flow from the inlet device to a piping device.

[0057] Furthermore, the second output of the first recording unit can be connected to at least one transfer line, e.g.

[0058] B. a second transfer line, a piping device, or a multi-nozzle device can be fluid-connected. In this way, it is possible to transfer a fluid flow from the inlet device to a piping device.

[0059] Furthermore, the inlet device can have a clamping unit with which a multi-nozzle device can be attached to at least one liquid line of an agricultural distribution machine.

[0060] The clamping unit can have at least one first and at least one second clamping element. The first clamping element can be configured to clamp at least one fluid line between itself and the second clamping element. The second clamping element can be configured to permit and / or establish a fluid connection for a first fluid to the inlet of the first receiving unit of the input device and / or a fluid connection for a second fluid to the inlet of the second receiving unit of the input device. Thus, a fluid flow of a first and / or second fluid can flow through the clamping unit or through the second clamping element, respectively, to subsequently reach the input device or its inlets.

[0061] Furthermore, it is conceivable that the present invention comprises an inlet device of a multi-nozzle device of an agricultural spreading machine, such as a field sprayer. The inlet device can have a first receiving unit for receiving a first liquid or a second receiving unit for receiving a second liquid. Regarding the further features of the first and / or second receiving unit, reference is made to the descriptions above.

[0062] Furthermore, the first or second receiving unit can have a fork to divide a fluid flow, for example, of a first or second fluid, that can flow through an inlet line of the first or second receiving unit. The fork can be arranged between a first and second end of the inlet line of the first / second receiving unit and / or between the inlet and at least one outlet of the first / second receiving unit. The fork can also be configured to divide a fluid flow, for example, of a first or second fluid, that can flow into an inlet line of the first or second receiving unit. The inlet of the first or second receiving unit can be located at a first end of an inlet line of the receiving unit. A first / second outlet and / or the fork of the first receiving unit can be located at a second end of an inlet line of the receiving unit.Thus, a fluid flow can be split at the second end of the fork.

[0063] A second aspect of the present invention comprises a multi-nozzle device for arrangement on a linkage or on at least one liquid line of an agricultural distribution machine.

[0064] It is expressly pointed out that the features of the input device, as mentioned under the first aspect, can be used individually or in combination with each other in the multi-nozzle device.

[0065] A multi-nozzle device for mounting on a boom or on at least one liquid line of an agricultural spreading machine comprises an inlet device for receiving a first and / or a second liquid into the multi-nozzle device as described in the first aspect. Using this multi-nozzle device, it is possible to reduce the number of nozzles required—compared to prior art solutions—while maintaining the same number of application options. In other words, prior art solutions require a significantly higher number of nozzles to achieve the same flexibility as the presented multi-nozzle device. These nozzles must be attached to liquid lines and / or a boom of the spreading machine. Therefore, cost reductions in assembly and manufacturing can be expected.

[0066] The multi-nozzle device can have a conduit for conveying and / or guiding a first and / or a second liquid to a first and / or to at least one second outlet device of the multi-nozzle device.

[0067] The inlet device and the piping device can be designed as a single, integrated part and / or as a single piece. This simplifies manufacturing and reduces costs. A third aspect of the present invention comprises a piping device of a multi-nozzle assembly for conveying and / or guiding a first and / or a second liquid to a first and / or at least a second outlet device of a multi-nozzle assembly.

[0068] It should be noted that the features of the input device, as mentioned under the first aspect, can be applied individually or in combination to the line device.

[0069] A conduit assembly of a multi-nozzle device, for conduiting and / or guiding a first and / or a second liquid to a first and / or to at least a second output device, comprises a first and a second transfer line for transferring a first liquid and / or a second liquid from an input device of a multi-nozzle device to a control device of a multi-nozzle device.

[0070] The first transfer line is fluid-communicating with an inlet device of a multi-nozzle device and / or with an inlet line of a first receiving unit of an inlet device of a multi-nozzle device. Thus, a liquid can be received from the inlet device and forwarded.

[0071] The second transfer line can be connected via fluid communication to an inlet device of a multi-nozzle system and / or to an inlet line of a second receiving unit of an inlet device of a multi-nozzle system. Thus, a liquid can be received from the inlet device and transferred.

[0072] The second transfer line can also be connected via fluid communication to a connecting line of an inlet device of a multi-nozzle system. This allows a liquid to be received from the inlet device and forwarded.

[0073] This design makes it possible to easily connect the piping system to an input device of a multi-nozzle device.

[0074] Furthermore, the piping device can be set up and configured to distribute or direct a first and / or a second liquid to a first and / or to at least one second outlet device of a multi-nozzle device.

[0075] Furthermore, the piping device can be set up and designed to distribute and / or direct a first and / or a second liquid to a first output device of a multi-nozzle device and to at least one control device of a multi-nozzle device.

[0076] Furthermore, the piping system and / or its transfer lines can be designed and / or arranged in such a way that a first and / or a second liquid, for example, from the interior of the piping system, can be directed or guided to an exterior of the piping system, for example, for delivery to a control unit of a multi-nozzle device. Thus, the piping system serves the efficient intake of liquids from an inlet device of a multi-nozzle device and also the conveyance or transfer of the received liquid(s) to a first and / or at least a second outlet device of a multi-nozzle device. This allows, for example, a change in the fluid direction or flow direction of a liquid.Furthermore, the first transfer line can be fluidly connected at its first end to a first output of a first receiving unit of an input device of a multi-nozzle device.

[0077] The second transfer line can be fluidly connected at its first end to a first output of a second receiving unit of an input device of a multi-nozzle device.

[0078] Additionally or alternatively, the second transfer line can be fluidly connected at its first end to a second output of a second receiving unit of an input device of a multi-nozzle device.

[0079] The first and / or second transfer line can also be connected at its second end to a control unit of a multi-nozzle device via fluid communication.

[0080] Furthermore, the first and / or second transfer line can be designed in such a way that a first and / or second liquid can be conveyed from at least one inlet to at least one outlet of the pipeline system.

[0081] The piping system can have at least one inlet per transfer line to receive a first and / or a second liquid from an inlet device of a multi-nozzle device.

[0082] The at least one inlet can be formed from an upstream, first end of the first and / or second transfer line.

[0083] A first inlet of the piping system can be fluidly connected to a first outlet of a first receiving unit of an inlet device of a multi-nozzle device for receiving a first liquid.

[0084] A second inlet of the piping system can be fluidly connected to a first outlet of a second receiving unit of an inlet device of a multi-nozzle device for receiving a second liquid.

[0085] A third inlet of the piping system for receiving a first liquid can also be fluidly connected to a second outlet of a second receiving unit of an inlet device of a multi-nozzle device.

[0086] Furthermore, the first and / or second transfer line can be designed in such a way that a first and / or second liquid can be conveyed from at least one inlet to at least one outlet of the pipeline system.

[0087] The piping system can have at least one outlet per transfer line to direct a first and / or a second liquid to at least one control unit of a multi-nozzle device.

[0088] At least one outlet can be formed from a downstream, second end of the first and / or second transfer line.

[0089] A first branch of the transmission system can be formed from a downstream, second end of the first transfer line. A second branch of the transmission system can be formed from a downstream, second end of the second transfer line.

[0090] A first section of the piping system can be fluidly connected to a control unit of a multi-nozzle device for the purpose of dispensing a first liquid.

[0091] A second outlet of the piping system can be fluidly connected to a control unit of a multi-nozzle device for the delivery of a first and / or second liquid.

[0092] Thus, it is possible to transfer liquid via the at least one outlet of the piping system to another system or to a control system of a multi-nozzle device.

[0093] Furthermore, the line installation may contain the transfer lines within it and / or include the first and / or second transfer line.

[0094] The first and / or second transfer line can have two sections. These two sections can be straight or curved. It is also possible for the two sections to be arranged at an angle to each other. The specific arrangement depends on the available space within the assembly for the piping system. One section, with at least one inlet, can comprise or be shaped like a hollow cylindrical channel. The other section, with at least one outlet, can form a channel with a hollow cylindrical recess, or be part of a concentric double pipe or a pipe-in-pipe arrangement. As a result, two fluid flows can be conveyed at a single point or position. Therefore, only one connection point is required for both fluid flows.

[0095] Furthermore, the conduit assembly can have a first and / or second transfer line for the transfer of a first liquid and / or a second liquid to a first outlet assembly of a multi-nozzle device.

[0096] The first and / or second transfer line can be connected via fluid communication to, for example, a first output device of a multi-nozzle device.

[0097] Furthermore, the first and / or second transfer line can be connected via fluid communication to a control unit of a multi-nozzle device.

[0098] Thus, it is possible to connect the first and / or second transfer line to a first output device and / or to a control device of a multi-nozzle system via fluid communication. Furthermore, the first and / or second transfer line and the first or second delivery line can be arranged coaxially and / or concentrically, at least in sections.

[0099] It is also conceivable that the first and / or second transfer line and the first or second transfer line are arranged and designed in such a way that both lines, at least in sections, have or form a pipe-within-a-pipe arrangement. As a result, two fluid flows can be conveyed at a common point or position. Thus, only one connection point is necessary for two fluid flows.

[0100] It is also possible for a transfer line and a delivery line to terminate or begin together on the same side of the piping system. Furthermore, the first or second transfer line and the first or second delivery line can be arranged and configured in such a way that a direct flow of a first and / or second fluid from a delivery line into a transfer line can be prevented or is impossible. In this way, fluid communication between the first or second transfer line and the first or second delivery line, for example without a control device for a multi-nozzle system, can be prevented or even made impossible.

[0101] Furthermore, the piping device and / or the first and / or second transfer line can be configured to receive a first and / or second liquid from a control device of a multi-nozzle device and / or to direct it to a first output device of a multi-nozzle device by directing or guiding the liquid to and within the piping device.

[0102] Furthermore, the piping device and / or its transfer lines can be designed and / or arranged in such a way that a first and / or a second liquid, for example from an outside of the piping device, to an inside of the piping device, for example for delivery to a first output device of a multi-nozzle device, can be directed or guided.

[0103] Furthermore, the conduit assembly may contain the transfer lines or the first and / or second transfer line inside it.

[0104] The first and / or second transfer line can, for example, each be straight.

[0105] The first end of each transfer line can form an inlet, and the second end of each transfer line can form an outlet. This allows a first or second fluid to flow from the inlet to the outlet. The transfer lines and transfer lines of the piping system can form an angle between 70 and 110 degrees, or a 90-degree angle, with an inlet line of a first receiving unit of an inlet device of a multi-nozzle device and / or with an inlet line of a second receiving unit of an inlet device of a multi-nozzle device. This allows for the deflection of a fluid.

[0106] Furthermore, the conduit assembly can have a first and / or second inlet to receive a first and / or a second fluid from a control unit of a multi-nozzle device and / or to convey it to a first outlet unit of a multi-nozzle device. The first and second inlets can be formed from the upstream end of each transfer line of the conduit assembly.

[0107] Furthermore, the first and second outlets of the piping system and the first and second inlets can be arranged coaxially and / or concentrically.

[0108] The first and second outlets of the piping system and the first and second inlets can be arranged and configured relative to each other in such a way that the outlet and inlet form at least a pipe-within-a-pipe arrangement. As a result, two fluid flows can be conveyed at a common point or position. Thus, only one connection point is necessary for two fluid flows.

[0109] Furthermore, the piping system can have a first and / or second outlet to direct a first and / or a second liquid to a first outlet of a multi-nozzle device. The first and / or second outlet can be arranged or oriented perpendicular to a first and / or second inlet of a transfer line.

[0110] Furthermore, the piping assembly can have a cylindrical recess at its geometric center, which allows a rotationally fixed connection between an output device, e.g., a first output device, of a multi-nozzle device and a selector device of a multi-nozzle device. In addition, one or each transfer line of the piping assembly can be fluidically connected to the cylindrical recess of the piping assembly. This allows a gate valve of a directional control unit of a multi-nozzle device, which can be arranged within a transfer line, to rest against a displacement unit of an output device of a multi-nozzle device, which can be arranged in the cylindrical recess of the piping assembly.

[0111] The piping device can further comprise a first rotary mounting for a first output device of a multi-nozzle device, in which a rotary table unit of an output device, e.g. a first output device, of a multi-nozzle device can be rotatably arranged.

[0112] The first rotary mounting can be cylindrical or hollow cylindrical, or in the form of a cylindrical recess, and / or have detents on its inner surface or on its inside, into which a spring arm of a rotary table unit of an output device, e.g., a first output device or a multi-nozzle device, can be engaged. This allows for the predefinable engagement or detent of an output device, e.g., a first output device or a multi-nozzle device, or the positioning of the output device relative to the line assembly. The first rotary mounting can also be rotationally symmetrical to ensure the rotation of an output device, e.g., a first output device or a multi-nozzle device.

[0113] Furthermore, the piping assembly can have a second rotary mount for a selection device of a multi-nozzle device and for selecting and / or determining the dispensing of a first and / or second liquid from a first and / or a second outlet device of a multi-nozzle device. The second rotary mount can be cylindrical, hollow cylindrical, or in the form of a cylindrical recess. The second rotary mount can also be rotationally symmetrical to ensure rotation of a selection device of a multi-nozzle device.

[0114] Furthermore, the first and / or second outlet can be located on the first side of the piping system, and at least one inlet can be located on the second side. The first and second sides can be opposite each other and / or oriented outwards.

[0115] At least one inlet of the piping system can be arranged within a first rotary mounting for a first outlet of a multi-nozzle device and / or connect directly to a first rotary mounting for a first outlet of a multi-nozzle device. Thus, the at least one inlet of the piping system can be offset by the height of the first outlet of a multi-nozzle device towards the interior of the piping system.Furthermore, the first and / or second outlet of a first and / or second transfer line of the piping system can be arranged within a second rotary mounting for a selection device of a multi-nozzle device and for selecting and / or determining the discharge of a first and / or second liquid from a first and / or a second outlet of a multi-nozzle device, and / or it can be directly connected to a second rotary mounting for a selection device of a multi-nozzle device and for selecting and / or determining the discharge of a first and / or second liquid from a first and / or a second outlet of a multi-nozzle device. Thus, the first and / or second outlet can be offset by the height of the first outlet of a multi-nozzle device towards the interior of the piping system.

[0116] Furthermore, the piping assembly can be designed as a single piece or as a single unit. A combination of a piping assembly of a multi-nozzle device with an inlet assembly of a multi-nozzle device can be designed as a single piece or as a single unit.

[0117] A fourth aspect of the present invention comprises a multi-nozzle device for arrangement on a boom or on at least one liquid line of an agricultural spreading machine. It is expressly pointed out that the features of the line assembly, as mentioned under the third aspect, can be used individually or in combination in the multi-nozzle device.

[0118] A multi-nozzle device for mounting on a boom or on at least one liquid line of an agricultural spreading machine, such as a field sprayer, comprises a line assembly for conveying and / or guiding a first and / or a second liquid to a first and / or at least a second outlet of the multi-nozzle device according to the third aspect. Using the multi-nozzle device, it is possible to reduce the number of nozzles required—compared to prior art solutions—while maintaining the number of application options. In other words, prior art solutions require a significantly higher number of nozzles to achieve the same flexibility as the presented multi-nozzle device. These nozzles must be attached to liquid lines and / or the boom of a spreading machine.Therefore, a reduction in costs regarding assembly and manufacturing can be expected.

[0119] Furthermore, the multi-nozzle device can have an inlet device for receiving a first and / or a second liquid into the multi-nozzle device. Such an inlet device is described, for example, in the first aspect of the present invention.

[0120] The inlet fitting and the conduit fitting can be designed as a single, integrated part and / or as a single piece. This simplifies manufacturing and saves costs.

[0121] The line equipment can be located downstream of the input equipment.

[0122] A fifth aspect of the present invention comprises a control device for controlling the flow direction of a first and / or a second liquid to a first and / or a second outlet device of a multi-nozzle device. It is expressly pointed out that the features of the inlet device, as mentioned in the first aspect, can be used individually or in combination in the control device.

[0123] Furthermore, it is pointed out that the features of the line equipment, as mentioned under the third aspect, can be applied individually or in combination to the control equipment.

[0124] A control device for directing the flow of a first and / or a second liquid to a first and / or a second outlet of a multi-nozzle device comprises a directional control valve unit for the controlled delivery of a first and / or second liquid to a first or a second outlet of a multi-nozzle device. Thus, the control device, with the aid of the directional control valve unit, can control the delivery of liquids such that either a first outlet of a multi-nozzle device or a second outlet of a multi-nozzle device can be supplied with the aforementioned liquid.

[0125] Furthermore, the directional control valve unit can be configured to direct a fluid flow of a first and / or second fluid either to a second output device of a multi-nozzle device or to a piping device of a multi-nozzle device.

[0126] Additionally or alternatively, the directional control valve unit can be configured to allow or block the flow of a first and / or second liquid either to a drain line of an extension unit of a second outlet device of a multi-nozzle device or to a first or second transfer line of a piping device of a multi-nozzle device.

[0127] Furthermore, the directional control valve unit can be configured to act against a first outlet of a multi-nozzle device or against a displacement unit of a first outlet of a multi-nozzle device in order to allow or block the flow of a first and / or second liquid to a second outlet of a multi-nozzle device or to a line of a multi-nozzle device. In this way, the directional control valve unit can be controlled by a displacement unit of a first outlet of a multi-nozzle device. Thus, for example, the displacement unit of a first outlet of a multi-nozzle device can control the directional control valve unit by manual operation of a user. In other words, the directional control valve unit can be configured and designed to be controlled by a displacement unit of a first outlet of a multi-nozzle device.The shifting unit can be manually operated and / or hand-operated and / or operated by hand or actuator and / or remotely operated.

[0128] Alternatively or additionally, the directional control valve unit can be arranged downstream of a valve unit of the control device.

[0129] In simplified terms, it can be provided that at least one control device, for example its directional control valve unit, is arranged between a first and a respective second output device of a multi-nozzle device.

[0130] For example, it may also be provided that a respective output device of a multi-nozzle device is integrally formed on the control device, e.g. on its directional control valve unit, and / or is attached or attachable, screwed on, or screwable to a first output device of a multi-nozzle device.

[0131] Furthermore, the directional control valve unit may include a gate valve which allows or blocks the path of a first and / or a second fluid to a first or a second outlet device.

[0132] The gate valve can be arranged within a transfer line of a piping system of a multi-nozzle device. Furthermore, the gate valve can have a smaller outer diameter than the inner diameter of a transfer line of a piping system of a multi-nozzle device. This allows the flow of a first and / or second fluid, e.g., from a valve unit, to a first outlet of a multi-nozzle device. Additionally, the gate valve can have a shape similar to a cylinder head screw, with a head and a shank whose diameter is smaller than that of the head. The shank can be arranged within a first or second transfer line of a piping system of a multi-nozzle device. The head can serve, for example, to close an opening to prevent the flow of fluid into the closed opening.The head can also make it easier for a feather to be inserted.

[0133] Furthermore, the gate valve can be spring-loaded, for example by a spring.

[0134] One end of the gate valve can be configured to rest against a spring of the directional control valve unit, and / or the other end of the gate valve can be configured to rest against a displacement unit of a first outlet device of a multi-nozzle assembly. In this way, the gate valve can be manually actuated via a displacement unit of a first outlet device of a multi-nozzle assembly. This design has the advantage that no additional lever is required to adjust the gate valve. Alternatively or additionally, the gate valve and / or a displacement unit of a first outlet device of a multi-nozzle assembly can also be remotely actuated and / or actuated via an actuator.

[0135] The end of the gate valve, on which a spring of the directional control valve unit can be or is arranged, can have a larger diameter than the end of the gate valve that can be or is arranged on a displacement unit of a first outlet device of a multi-nozzle device. This facilitates the contact of the spring.

[0136] Furthermore, the directional control valve unit can include a spring with which a gate valve of the directional control valve unit can be biased or biased in one direction. The spring can be biased such that a fluid flow of a first and / or second fluid to a second outlet device can be permitted and / or that a fluid flow of a first and / or second fluid to a line device of a multi-nozzle device can be blocked and / or that a fluid flow of a first and / or second fluid to the first outlet device of a multi-nozzle device can be blocked. This is also possible in reverse.Conversely, it is possible that a liquid flow of a first and / or second liquid to a second output device can be blocked and / or that a liquid flow of a first and / or second liquid to a line device of a multi-nozzle device can be allowed and / or that a liquid flow of a first and / or second liquid to the first output device of a multi-nozzle device can be permitted.

[0137] Furthermore, the spring can be pre-tensioned in such a way that a fluid flow of a first and / or second liquid to a drain line of an extension unit of a second outlet device is possible or permitted, and / or that a fluid flow of a first and / or second liquid to a first or second transfer line of a piping unit of a multi-nozzle device can be blocked or prevented. Conversely, a fluid flow of a first and / or second liquid to a drain line of an extension unit of a second outlet device can be blocked or prevented, and / or a fluid flow of a first and / or second liquid to a first or second transfer line of a piping unit of a multi-nozzle device can be possible or permitted.

[0138] The spring can also be arranged or positioned within a drain line of an extension unit of a second outlet device of a multi-nozzle device.

[0139] Furthermore, the control device can be set up and designed in such a way that, for example, only two switching states, such as "open" and "closed" or continuously opening or continuously closing, can be realized or implemented with it.

[0140] The control device can include a valve, a PWM valve, or a pulse-width modulated valve, with which two switching states, for example "open" and "closed" or continuously opening or continuously closing, can be implemented. The valve, PWM valve, or pulse-width modulated valve can be positively and / or frictionally attached to a third port of a valve unit of the control device.

[0141] Furthermore, the control device can include a valve unit for flow control of a first and / or a second liquid to a first and / or a second output device of a multi-nozzle device.

[0142] The valve unit can be fluid-communicating with a line of a multi-nozzle device. Furthermore, the valve unit can be fluid-communicating with a second output device of a multi-nozzle device and / or with a first or second transfer line of a line of a multi-nozzle device and / or with a first or second transfer line of a line of a multi-nozzle device.

[0143] Furthermore, the valve unit can be fluid-communicating with a first or second outlet of a piping system of a multi-nozzle device. Additionally, the valve unit can be fluid-communicating with a first or second inlet of a piping system of a multi-nozzle device.

[0144] Furthermore, the valve unit can be fluid-communicating with a second outlet of a multi-nozzle device. It can also be provided that the valve unit can be fluid-communicating with a drain line of an extension unit of a second outlet of a multi-nozzle device. Additionally, the valve unit can have a first connection for connection to a line of a multi-nozzle device. The first connection can be designed to be complementary to a transfer line, e.g., a second transfer line, and / or a transfer line, e.g., a second transfer line, of a line of a multi-nozzle device in order to receive and discharge a first and / or second liquid.

[0145] Furthermore, the first connection can have a supply line and a return line for a first and / or second liquid. The supply line and the return line can be arranged and / or configured coaxially and / or concentrically. The supply line and the return line can also be arranged and configured relative to each other in such a way that they at least partially form a pipe-within-a-pipe arrangement. As a result, two liquid flows can be routed at a single point or position. Thus, only one connection point is required for two liquid flows.

[0146] The supply line can be connected via fluid communication to a transfer line, e.g., to a second transfer line, a line assembly, or a multi-nozzle device.

[0147] The discharge can be connected via fluid communication to a transfer line, e.g. to a second transfer line, a line assembly of a multi-nozzle device.

[0148] A valve seat of the valve unit can be arranged between the inlet and the outlet.

[0149] Furthermore, the valve unit can have a second connection for linking to the piping of a multi-nozzle device. This second connection can have several mounting options, for example in the form of holes, allowing the valve unit to be attached to the piping of a multi-nozzle device at different angles. The mounting options can be arranged in a circle.

[0150] Furthermore, the valve unit can have a third port for connecting a valve of the control device. A valve of the control device can be frictionally and / or positively engaged at this third port. The third port can also have a valve seat at which a fluid flow of a first and / or second fluid through the valve unit can be controlled by a valve of the control device.

[0151] Furthermore, the valve seat may be arranged downstream of an inlet to a first port of the valve unit. Alternatively, the valve seat may be arranged upstream of the outlet to a first port of the valve unit. The valve seat may also be configured such that a flow of a first and / or second fluid from a valve of the control device can be permitted or prevented.

[0152] The discharge can be fluid-communicating with a transfer line, e.g. to a second transfer line, a line device of a multi-nozzle device, and / or the discharge can be fluid-communicating with a drain line of an extension unit of a second output device of a multi-nozzle device.

[0153] Furthermore, the valve unit can have a fourth port for connection to a second outlet of a multi-nozzle device for dispensing a first and / or a second liquid from the multi-nozzle device. The fourth port can have a drain for a first and / or second liquid. The drain of the fourth port and the drain of the first port can be configured as a single drain. The activation or selection of the respective drain can be made by a gate valve of the directional control valve unit or its relative positioning to the valve unit.

[0154] Furthermore, the fourth connection can be used to connect a drain line of an extension unit to a second output device of a multi-nozzle device via fluid communication.

[0155] Furthermore, the valve unit can be arranged between a piping device and a second output device of a multi-nozzle device.

[0156] The directional control valve unit can be arranged partly inside the valve unit, partly inside a piping system, and partly inside a second outlet unit of a multi-nozzle device.

[0157] A sixth aspect of the present invention comprises a multi-nozzle device for arrangement on a linkage or on at least one liquid line of an agricultural spreading machine.

[0158] It is expressly pointed out that the features of the control device, as mentioned under the fifth aspect, can be used individually or in combination with each other in the multi-nozzle device.

[0159] A multi-nozzle device for mounting on a boom or on at least one liquid line of an agricultural spreading machine, such as a field sprayer, comprises at least one control device according to the fifth aspect. Using this multi-nozzle device, it is possible to reduce the number of nozzles required—compared to prior art solutions—while maintaining the same number of application options. In other words, prior art solutions require a significantly higher number of nozzles to achieve the same flexibility as the presented multi-nozzle device. These nozzles must be attached to liquid lines and / or the boom of a spreading machine. Therefore, cost reductions in assembly and manufacturing can be expected.

[0160] Furthermore, the present invention has the advantage that, compared to the prior art, fewer valves are required within and / or on the multi-nozzle device. This is because, in the prior art, it is necessary to use one valve per spray nozzle of an output device. Alternatively, it is also known from the prior art that a spray nozzle of an output device is supplied by a central valve of the nozzle device and is therefore inflexible in its application. The design or configuration of the at least one control device between a line assembly and / or an input device of the multi-nozzle device and an extension unit of an output device, such as...With a second output device, the multi-nozzle device, additional valves or a high number of valves of the at least one control device can be dispensed with and / or the flexibility can be increased while maintaining the same number of valves of the at least one control device.

[0161] A seventh aspect of the present invention comprises an output device, e.g., a first or a second output device, of a multi-nozzle device. It is noted that the features of the piping device, as mentioned under the third aspect, can be applied individually or in combination to the output device.

[0162] Furthermore, it should be noted that the features of the control device, as mentioned under the fifth aspect, can be applied individually or in combination to the output device.

[0163] An output device, e.g. a first or a second output device of a multi-nozzle device and for dispensing a first and / or a second liquid, comprises a displacement unit for controlling a control device of a multi-nozzle device.

[0164] The displacement unit is designed and configured to translationally displace at least a part of at least one control unit of a multi-nozzle device. This translational displacement makes it possible to control the flow of liquid such that it can selectively flow from either a first outlet of a multi-nozzle device or a second outlet of a multi-nozzle device.

[0165] Furthermore, the displacement unit can be configured and designed to effect a translation of a part of at least one control unit of a multi-nozzle device through its rotation. Thus, one type of movement can be converted into another.

[0166] The displacement unit can also be set up and designed to translationally displace or move a gate valve of a directional control valve unit of at least one control device of a multi-nozzle device.

[0167] Furthermore, the displacement unit can be set up and designed to abut against one end of a gate valve of a directional control unit of at least one control device of a multi-nozzle device and to move or displace the gate valve translationally.

[0168] In light of the aforementioned feature groups, it is therefore possible to move a control unit of a multi-nozzle device, or a part of a control unit of a multi-nozzle device, or a gate valve of a control unit of a multi-nozzle device translationally by rotating the displacement unit. Furthermore, the output unit can be manually operated, allowing, for example, a gate valve of a control unit of a multi-nozzle device to be moved and / or adjusted via the displacement unit. Such a design has the advantage that no additional lever is required to adjust the gate valve. Alternatively or additionally, a gate valve of a control unit of a multi-nozzle device and / or the displacement unit can also be remotely operated and / or actuated via an actuator.

[0169] Furthermore, the displacement unit can have a cylindrical shape whose base deviates from a circular area and / or whose height extends in the axial direction. The base can have a geometric center.

[0170] The displacement unit can have an outer shape in which the edge of its outer shape can have different distances to a geometric center of the displacement unit and / or to a geometric center of the output device, e.g. a first output device of a multi-nozzle device.

[0171] Due to the deviation from the circular surface and / or due to different distances to a geometric center of the displacement unit, a rotation about an axis of rotation and / or about a geometric center of the displacement unit can cause at least one control device or a shut-off valve of a directional control unit of at least one control device of a multi-nozzle device to perform a translational movement.

[0172] The displacement unit and / or the output device can be rotatable about its axis of rotation and / or about its geometric center or about the geometric center of the output device, e.g., a first output device of a multi-nozzle device.

[0173] Furthermore, the displacement unit can have at least one recess or at least one projection in the radial direction and / or on its outer surface. Using the at least one recess or at least one projection, an outer shape can be formed in which the edge has varying distances from a geometric center of the displacement unit and / or the output device.

[0174] Furthermore, the displacement unit and / or the output device can be designed to rotate about the axis of rotation of the output device, e.g., a first output device of a multi-nozzle assembly. The axis of rotation of the output device can be located at the geometric center of the displacement unit and / or at the geometric center of the output device, e.g., a first output device of a multi-nozzle assembly.

[0175] Furthermore, the displacement unit can be arranged on a rotary table unit of the output device, e.g., on a first output device of a multi-nozzle device, and / or the displacement unit can rise from or project from a plane of a rotary table unit of the output device, e.g., a first output device of a multi-nozzle device, in the axial direction. The axial direction can be oriented in the same direction as the axis of rotation or parallel to the axis of rotation of the displacement unit and / or the output device.

[0176] Furthermore, the output device, e.g. a first output device of a multi-nozzle device, can have a rotary connection to transmit a rotation of the output device to an axially spaced selection device of a multi-nozzle device for determining the dispensing of a first and / or second liquid from the output device or from a first and / or from at least one second output device.

[0177] The rotary connection can be located on or attached to the transfer unit. The rotary connection can also extend away from the transfer unit and / or from a rotary table unit of the output device.

[0178] Furthermore, the rotary connection can have at least two projections in the axial direction, which are spaced apart from each other in the circumferential direction, so that a selection device of a multi-nozzle device for determining the dispensing of a first and / or second liquid from the outlet device or from a first and / or from at least one second outlet device can engage in a torque-transmitting manner between the at least two projections.

[0179] The rotary connection can have at least two projections, which can extend along the height of the displacement unit and / or in the axial direction of the output device. The rotary connection can extend away from the displacement unit, e.g., in the axial direction.

[0180] Furthermore, the rotary connection or its at least two projections can be designed similarly to a claw of a jaw coupling or similarly to a coupling part of a jaw coupling in order to engage, or be able to engage, with a geometrically adapted counterpart of a selector device of a multi-nozzle device. The at least two projections can be arranged geometrically such that they form a coded plug connection in which correspondingly geometrically coded counterparts of the output device, e.g., a first output device of a multi-nozzle device, and a selector device of a multi-nozzle device engage, or are able to engage, with each other. In this way, only one type of connection is possible, thus preventing incorrect assembly.

[0181] Furthermore, the output device, e.g. a first output device of a multi-nozzle device, can have a rotary table unit for rotatable mounting in a first rotary mounting of a line device of a multi-nozzle device.

[0182] The rotary table unit can be rotatably arranged in a first rotary mounting of a line assembly of a multi-nozzle device, or the output device, e.g., at least a second output device of a multi-nozzle device, can have a rotary table unit for rotatable mounting in a second rotary mounting of an extension unit of the output device, e.g., a second output device of a multi-nozzle device.

[0183] The rotary table unit can be rotatably arranged in a second rotary mount of an extension unit of the output device, e.g. a second output device of a multi-nozzle device.

[0184] The turntable unit can also be disc-shaped and / or cylindrical.

[0185] Furthermore, the output device, e.g. a first or at least a second output device of a multi-nozzle device or its rotary table unit, can have a rotationally symmetrical shape.

[0186] The displacement unit and at least one nozzle carrier of the output device, e.g., of a first output device of a multi-nozzle device, can be arranged on opposite / different sides of the rotary table unit.

[0187] Furthermore, the rotary table unit can have at least one passage which leads a first and / or second liquid from a piping device of a multi-nozzle device, for example via an extension unit of the output device, e.g. a second output device of a multi-nozzle device, to at least one nozzle carrier of the output device.

[0188] Furthermore, two passages can be arranged equidistant from each other in the circumferential direction of the outlet device. The rotary table unit can be designed such that the at least one passage forms a fluid connection with a drain of a piping device of a multi-nozzle assembly, in order to direct a first and / or a second liquid to at least one nozzle carrier of the outlet device, e.g., of a first outlet device and / or at least one second outlet device of a multi-nozzle assembly.

[0189] The rotary table unit can further be designed such that the at least one passage forms a fluid connection with a drain line of an extension unit of the output device, e.g. at least one second output device of a multi-nozzle device, in order to direct a first and / or a second liquid to the nozzle carrier.

[0190] Furthermore, the turntable unit can have at least one spring arm to generate a force.

[0191] The rotary table unit can have at least one spring arm on its radially outer side to engage in detents of a first rotary mounting of a line assembly of a multi-nozzle device or in detents of a second rotary mounting of an extension unit of the output device, e.g., a second output device of a multi-nozzle device. This allows for predefinable detent and / or positioning of the output device relative to a line assembly of a multi-nozzle device or relative to an extension unit of the output device, e.g., a second output device of a multi-nozzle device.

[0192] The at least one spring arm can be designed to generate a spring force in the radial direction. At least two spring arms can be arranged equidistant from each other in the circumferential direction of the output device.

[0193] Furthermore, the output device, e.g. a first output device or at least a second output device of a multi-nozzle device, can have at least one nozzle carrier on which at least one spray nozzle and / or nozzle cap can be detachably and / or non-destructively attached.

[0194] The at least one nozzle carrier and the displacement unit can be arranged on opposite sides of a rotary table unit of the output device, e.g. a first output device of a multi-nozzle device.

[0195] The at least one nozzle carrier can be hollow cylindrical and / or project from the rotary table unit or extend away from the rotary table unit, for example in axial and radial directions.

[0196] Furthermore, the at least one nozzle carrier and at least one passage of a rotary table unit of the output device can be fluidly connected to each other. Thus, a liquid can flow through the at least one nozzle carrier and through the at least one passage.

[0197] Furthermore, the output device, e.g., a first or at least a second output device of a multi-nozzle device, can be fluid-communicating with a line device of a multi-nozzle device. The output device, e.g., a first or at least a second output device of a multi-nozzle device, can be arranged downstream of a line device of a multi-nozzle device and / or downstream of a control device of a multi-nozzle device.

[0198] Furthermore, the output device, e.g. a first or at least a second output device of a multi-nozzle device, can be connected via fluid communication to a line device of a multi-nozzle device.

[0199] Alternatively or additionally, at least one outlet device may be provided, which has one or more spray nozzles and / or nozzle holders and which is preferably not adjustable and / or not rotatable and / or which is alternatively or additionally integrally formed on a piping device and / or inlet device. In particular, alternatively or additionally, at least one outlet device without a sliding unit may be provided.

[0200] The outlet unit, e.g., at least one second outlet unit of a multi-nozzle device, can include an extension unit for relocating a second outlet unit away from a first outlet unit. The extension unit can have a drain line to which a second rotary mount of the extension unit can be connected. Furthermore, the extension unit can have a second rotary mount for a turntable unit of the outlet unit, e.g., a second outlet unit of a multi-nozzle device, in which the turntable unit can be rotatably mounted. Using the extension unit, a distance of 25 cm between two spray nozzles or between two nozzle holders of two outlet units, e.g., two second outlet units of a multi-nozzle device, can be achieved.

[0201] The drain line and a fourth connection of a valve unit of a control device of a multi-nozzle device can be matched and / or designed identically to ensure and / or guide a consistent or constant fluid flow.

[0202] The drain line and a connecting transfer line of a piping system of a multi-nozzle device can extend in opposite directions.

[0203] The drain line and a transfer line of a multi-nozzle system can have the same diameter, length, and / or volume. This allows for a seamless switchover of the fluid flow from the drain line to the transfer line, ensuring that fluid immediately exits either the drain line or the transfer line after the switchover. In other words, dead volume is prevented or eliminated.

[0204] Furthermore, the output device can be designed as a single unit or in one piece.

[0205] The outlet device, e.g., a first outlet device, and a selector device of a multi-nozzle assembly can be rotatably connected to each other and / or non-rotatably connected, such that rotation of the outlet device causes or results in rotation of the selector device. A rotatable or non-rotatable connection is possible, for example, via projections that interlock in such a way that the connection is similar to a jaw coupling. Furthermore, in a first rotational state of the outlet device, e.g., a first outlet device, it can be, or be capable of being, supplied with a first and second fluid.

[0206] In a second rotational state of the output device, e.g., a first output device, it can be, for example, only, through which a first or second liquid flows or can be supplied.

[0207] In a third rotational state of the output device, e.g., a first output device, it can neither be flowed through nor be supplied by a first or a second liquid.

[0208] Furthermore, in a first rotational state of the output device, e.g. a first output device, a first liquid can flow from an input device of a multi-nozzle device to a first or at least a second output device.

[0209] Additionally or alternatively, in the first rotational state of the output device, e.g. a first output device, a second liquid can flow from an input device of a multi-nozzle device to a second or first output device.

[0210] It is also possible to design a selection device of a multi-nozzle device in conjunction with the first output device or with its displacement unit such that in the first rotational state of the output device, e.g. a first output device, a first liquid can flow from an input device of a multi-nozzle device to a second output device and a second liquid can flow from the input device to a further second output device.

[0211] In a second rotational state of the output device, e.g. a first output device, a first or a second liquid can flow from an inlet device of a multi-nozzle device to a first or second output device.

[0212] In a third rotational state of the output device, e.g., a first output device, neither a first nor a second liquid can flow from an input device of a multi-nozzle device to a first and / or second output device.

[0213] Furthermore, in a first rotational state of the output device, e.g., a first output device, a first passage of a selector device of a multi-nozzle device, a first output of a first input unit of an input device of a multi-nozzle device, and at least one passage of a rotary table unit of a first output device can be part of a common fluid connection. In this way, a first fluid can enter at the input device and exit at the output device, e.g., at a nozzle holder of a first output device.

[0214] In a first rotational state of the output device, e.g., a first output device, a second passage of a selector device of a multi-nozzle device, a first output of a second input unit of an input device of a multi-nozzle device, and at least one passage of a rotary table unit of a first output device can be part of a common fluid connection. In this way, a second fluid can enter at the input device and exit at an output device, e.g., at a nozzle holder of an output device.

[0215] Alternatively, it is possible that in a first rotational state of the output device, e.g., a first output device, a first passage of a selector unit of a multi-nozzle device, a second output of a second input unit of an input device of a multi-nozzle device, and at least one passage of a rotary table unit of a first output device are part of a common fluid connection. In this way, a second fluid can enter at the input device and exit at an output device, e.g., a nozzle holder of a first output device.

[0216] Furthermore, in a second rotational state of the output device, e.g., a first output device, at least one first passage of a selection device of a multi-nozzle device, one first outlet of a first input unit of an input device of a multi-nozzle device, and one passage of a rotary table unit of a second output device can be part of a common fluid connection. In this way, a first fluid can enter at the input device and exit at an output device, e.g., at a nozzle holder of at least one second output device.

[0217] In a second rotational state of the output device, e.g., a first output device, at least one first passage of a selector unit of a multi-nozzle device, one first outlet of a second input unit of an input device of a multi-nozzle device, and one passage of a rotary table unit of a second output device can be part of a common fluid connection. Thus, it is possible for a first fluid to enter at the input device and exit at an output device, e.g., at a nozzle holder of at least one second output device.

[0218] In a second rotational state of the output device, e.g., a first output device, a fluid connection can be prevented by or via a selection device of a multi-nozzle device, so that a second fluid can enter at an input device of a multi-nozzle device or at a second input unit of an input device of a multi-nozzle device, but cannot exit anywhere.

[0219] Furthermore, in a third rotational state of the output device, e.g., a first output device, a fluid connection can be prevented by or via a selection device of a multi-nozzle device, so that a first fluid can enter at the input device of a multi-nozzle device or at a first input unit of an input device of a multi-nozzle device, but cannot exit anywhere.

[0220] Furthermore, in a third rotational state of the outlet device, e.g., a first outlet device, a fluid connection can be prevented by or via a selection device of a multi-nozzle device, so that a second fluid can enter at an inlet device of a multi-nozzle device or at a second inlet unit of an inlet device of a multi-nozzle device, but cannot exit anywhere. An eighth aspect of the present invention comprises a multi-nozzle device for arrangement on a linkage or on at least one fluid line of an agricultural spreading machine. It is expressly pointed out that the features of the outlet device, as mentioned under the seventh aspect, can be used individually or in combination with one another in the multi-nozzle device.

[0221] A multi-nozzle device for arrangement on a boom or on at least one liquid line of an agricultural distribution machine, such as a field sprayer, comprises a first outlet device according to the seventh aspect and / or at least a second outlet device according to the seventh aspect.

[0222] Furthermore, the multi-nozzle device may have a conduit for conveying and / or guiding a first and / or a second liquid to a first and / or at least a second outlet device of the multi-nozzle device, as described in the third aspect.

[0223] The first output device can be arranged in a second rotary mount of the line device.

[0224] Furthermore, a rotary table unit of the at least one second output device can be arranged in a second rotary mount of an extension unit of the at least one second output device.

[0225] The multi-nozzle device makes it possible to reduce the number of nozzles compared to prior art solutions, while maintaining the same number of application options. In other words, prior art solutions require a significantly higher number of nozzles to achieve the same flexibility as the presented multi-nozzle device. These nozzles must be attached to liquid lines and / or the boom of a distribution machine. Therefore, cost reductions in assembly and manufacturing can be expected.

[0226] A ninth aspect of the present invention comprises a selection device for selecting and / or determining the dispensing of a first and / or second liquid from a first and / or at least one second outlet device of a multi-nozzle device.

[0227] It is expressly pointed out that the features of the entry device, as mentioned under the first aspect, can be applied individually or in combination to the selection device.

[0228] Furthermore, it is pointed out that the features of the management system, as mentioned under the third aspect, can be applied individually or in combination to the election system.

[0229] A selection device for choosing and / or determining the dispensing of a first and / or second liquid from a first and / or at least one second outlet of a multi-nozzle device comprises a rotary connection for torque transmission to a rotary connection of an outlet, e.g., a first outlet of a multi-nozzle device, to accommodate rotation from an axially spaced outlet of a multi-nozzle device. The rotary connection allows the selection device to be rotated, thereby enabling the selection of a liquid and an outlet of a multi-nozzle device for dispensing a liquid.

[0230] Furthermore, the rotary connection can be designed to engage in a rotary connection of an output device, e.g., a first output device, a multi-nozzle device, so that a rotation of the output device causes a rotation of the selection device.

[0231] Furthermore, the selection device can comprise a disc-shaped and / or cylindrical base body with two opposing, axially spaced end faces.

[0232] The rotary connection can be located centrally in the base body and / or centrally in an end face of the base body.

[0233] Furthermore, the rotary connection can have a first cylindrical recess. The first cylindrical recess can penetrate the base body, for example, to two-thirds, three-quarters, or half its height in the axial direction.

[0234] Furthermore, the rotary connection can include a second cylindrical recess that penetrates the base body to one-third, one-quarter, or one-half of its height in the axial direction. The first cylindrical recess can have a larger diameter than the second. In total, the first and second cylindrical recesses can penetrate the base body completely and / or entirely.

[0235] Furthermore, within the base body, a transition from the first to the second recess can form a stop in the axial direction for a rotary connection of an output device, e.g., a first output device, a multi-nozzle device.

[0236] Furthermore, the rotary connection can have at least two projections that are spaced apart from each other in the circumferential direction, so that an output device, e.g. a first output device, of a multi-nozzle device, for example with its rotary connection, can engage between the at least two projections.

[0237] The rotary connection or its at least two projections can be designed similarly to a claw of a jaw coupling or similarly to a coupling part of a jaw coupling in order to engage with a geometrically adapted counterpart of an output device, e.g., a first output device or a multi-nozzle device. The at least two projections can be arranged geometrically such that they form a coded plug connection in which correspondingly geometrically coded counterparts of an output device, e.g., a first output device, a multi-nozzle device, and the selector device of a multi-nozzle device engage with each other.In this way, only one type of connection is possible, thus preventing incorrect assembly.

[0238] The at least two projections can be cuboid in shape. Furthermore, the at least two projections can extend radially inwards from the edge or the cylindrical surface of the first cylindrical recess of the rotary connection. Additionally, the at least two projections can extend axially from the second cylindrical recess at the transition between the first and second cylindrical recesses. The at least two projections can also extend axially from the stop and / or towards an end face of a base body of the selection device and / or extend along the height of a base body of the selection device. It is also possible for the at least two projections to extend axially beyond one of the two end faces of a base body of the selection device.Alternatively, it is possible that the at least two projections protrude in an axial direction from one of the two end faces of a base body of the selection device.

[0239] Furthermore, as an alternative or in addition to a rotary connection of the selection device, the selection device has at least one first and at least one second passage for the flow of a first and / or second liquid. The at least one first and the at least one second passage can be shaped differently or have different forms or cross-sectional shapes.

[0240] It can be provided that the at least one first pass is assigned to a first liquid and the at least one second pass to a second liquid. In other words, the at least one first pass can be configured to convey a first liquid, and / or the at least one second pass can be configured to convey a second liquid.

[0241] The first or at least one passage can be designed as a bore or in the form of a cylindrical recess. The first or at least one passage can also have a polygonal shape and / or a circular cross-section.

[0242] The at least one second passage can have a horseshoe-shaped, crescent-shaped, slit-shaped, and / or polygonal cross-section, or be designed as a recess with a general cylindrical shape, the curved course of which within a plane forms a horseshoe, crescent, slit, and / or polygonal shape. In other words, the second passage can be designed in the manner of a slit, e.g., a curved one, or, in the case of a polygonal surface, in any desired shape.

[0243] In the present description, a general cylindrical shape can be understood as a shape described by a general cylinder. Such a general cylinder comprises an arbitrary curved path within a plane, which is displaced along a specific distance, where the specific distance is not contained in the plane in which the general cylinder exhibits the arbitrary curved path. Such a general cylinder is also known from mathematics. For example, the at least one second passage can also be hollow cylindrical or in the form of a hollow cylindrical recess.

[0244] Furthermore, the first and / or second passage can also be shaped differently, for example, at least approximately prism-shaped and / or with at least an approximately triangular, rectangular, or other polygonal base and / or ground shape. A passage can be formed by a geometric body created by the parallel translation of a planar polygon along a line or segment not lying in that plane in space. This can also be described as the extrusion of the polygon. Furthermore, it can be provided that a different number of first and second passages are configured in the selection device. For example, several first passages and only a single second passage can be provided. However, it is also possible that several second passages and only a single first passage are provided.

[0245] Furthermore, multiple first passes and / or multiple second passes may be provided, whereby the number of first passes may exceed the number of second passes or vice versa.

[0246] Furthermore, it can be provided that the at least one first pass and the at least one second pass have different, the same, or identical flow cross-sections. In this way, different, the same, or identical flow rates or volumetric flow rates of a first and / or second liquid can flow through the at least one first and / or the at least one second pass. Consequently, it is possible to direct different, the same, or identical flow rates of a liquid towards at least one outlet device and / or towards different outlet devices of a multi-nozzle device. The terms "same" or "identical" can encompass deviations in the at least one first and / or at least one second pass with regard to flow cross-sections, flow rates, and / or volumetric flow rates within the range of + / - 5%.

[0247] Furthermore, the at least one first passage and the at least one second passage can be arranged within a base body of the selection device. The at least one first passage and the at least one second passage can also be arranged within a base body of the selection device and / or within the end faces in such a way that, by rotating the selection device, flow through either the at least one first passage and / or the at least one second passage can be selected; for example, this is possible in conjunction with a piping system of a multi-nozzle device.

[0248] The at least one first pass and the at least one second pass can be spaced apart from each other in the circumferential direction of the selection device or equidistant from each other. This makes it possible to dispense different liquids from different outlet devices of a multi-nozzle device at different rotation angles.

[0249] Furthermore, it is alternatively or additionally possible to direct different flow rates of the same liquid to at least one outlet and / or to different outlets of a multi-nozzle device at different rotation angles. In other words, different rotation angles of the selector can be provided for different flow rates or volume flows of a first and / or second liquid. This can be achieved, for example, by varying the diameter, hydraulic diameter, or flow cross-section of at least one first and / or second passage.

[0250] Furthermore, it may alternatively or additionally be provided that a cross-section or flow cross-section of the at least one first and / or second passage has an average diameter of at least 3 mm. 2 , preferably between 3 and 2000 mm 2and especially preferably between 5 - 100 mm 2 , exhibits or amounts to. Furthermore, preferably, the respective sizes of the cross-sections or flow cross-sections of at least one first and at least one second pass or several first and / or second passes can differ from each other.

[0251] Furthermore, the selection device can be arranged downstream of an input device of a multi-nozzle device and / or upstream of a line device of a multi-nozzle device.

[0252] Furthermore, the selection device can be arranged between an input device of a multi-nozzle device and a line device of a multi-nozzle device.

[0253] The selector and an output device, e.g., a first output device, of a multi-nozzle device can be rotatably connected to each other and / or non-rotatably connected, such that a rotation of the output device causes or results in a rotation of the selector. A rotatable or non-rotatable connection is possible, for example, via projections that can interlock in such a way as to form a connection similar to a jaw coupling.

[0254] Furthermore, in a first rotational state of the selection device, it can be or be capable of being flowed through by a first and second liquid.

[0255] In a second rotational state of the selection device, it can be, for example, only, through which a first or second liquid flows, or be capable of flowing through it.

[0256] In a third rotational state of the selection device, it can neither be permeated by a first nor by a second liquid.

[0257] Furthermore, in a first rotational state of the selection device, a first liquid can flow from an inlet device of a multi-nozzle device to a first or at least a second outlet device of a multi-nozzle device.

[0258] Additionally or alternatively, in the first rotational state of the selection device, a second liquid can flow from an inlet device of a multi-nozzle device to a second or first outlet device of a multi-nozzle device.

[0259] It is also possible to design the selection device in conjunction with the first output device or with its displacement unit in such a way that, in the first rotational state of the selection device, a first liquid can flow from an input device of a multi-nozzle device to a second output device of a multi-nozzle device, and a second liquid can flow from the input device to a further second output device of a multi-nozzle device.

[0260] In a second rotational state of the selection device, a first or a second liquid can flow from an inlet device of a multi-nozzle device to a first or second outlet device of a multi-nozzle device.

[0261] In a third rotational state of the selection device, neither a first nor a second liquid can flow from an inlet device of a multi-nozzle device to a first and / or second outlet device of a multi-nozzle device.

[0262] Furthermore, in a first rotational state of the selector device, a first passage of the selector device, a first outlet of a first input unit of an input unit of a multi-nozzle device, and at least one passage of a rotary table unit of a first output unit of a multi-nozzle device can be part of a common fluid connection. In this way, a first fluid can enter at the input unit and exit at an output unit, e.g., at a nozzle holder of a first output unit of a multi-nozzle device.

[0263] In a first rotational state of the selector device, a second passage of the selector device, a first outlet of a second inlet unit of an inlet unit of a multi-nozzle device, and at least one passage of a rotary table unit of a first outlet unit of a multi-nozzle device can be part of a common fluid connection. In this way, a second fluid can enter at the inlet unit and exit at an outlet unit, e.g., at a nozzle holder of an outlet unit of a multi-nozzle device.

[0264] Alternatively, in a first rotational state of the selector device, a first passage of the selector device, a second outlet of a second inlet unit of an inlet unit of a multi-nozzle device, and at least one passage of a rotary table unit of a first outlet unit of a multi-nozzle device are part of a common fluid connection. In this way, a second fluid can enter at the inlet unit and exit at an outlet unit, e.g., at a nozzle holder of a first outlet unit of a multi-nozzle device.

[0265] Furthermore, in a second rotational state of the selector device, at least one first passage of the selector device, one first outlet of a first inlet unit of an inlet unit of a multi-nozzle device, and one passage of a rotary table unit of a second outlet unit of a multi-nozzle device can be part of a common fluid connection. In this way, a first fluid can enter at the inlet unit and exit at an outlet unit, e.g., at a nozzle holder of at least one second outlet unit of a multi-nozzle device.

[0266] In a second rotational state of the selector device, at least one first passage of the selector device, one first outlet of a second inlet unit of an inlet unit of a multi-nozzle device, and one passage of a rotary table unit of a second outlet unit of a multi-nozzle device can be part of a common fluid connection. Thus, it is possible for a first fluid to enter at the inlet unit and exit at an outlet unit, e.g., at a nozzle holder of at least one second outlet unit of a multi-nozzle device.

[0267] In a second rotational state of the selection device, a fluid connection through or via the selection device can be prevented, so that a second fluid can enter at an inlet device of a multi-nozzle device or at a second inlet unit of an inlet device of a multi-nozzle device, but cannot exit anywhere and cannot flow through the selection device anywhere.

[0268] Furthermore, in a third rotational state of the selection device, a fluid connection through or via the selection device can be prevented, so that a first fluid can enter at the inlet device of a multi-nozzle device or at a first inlet unit of an inlet device of a multi-nozzle device, but cannot escape anywhere and cannot flow through the selection device anywhere.

[0269] Furthermore, in a third rotational state of the selection device, a fluid connection through or via the selection device can be prevented, so that a second fluid can enter at an inlet device of a multi-nozzle device or at a second inlet unit of an inlet device of a multi-nozzle device, but cannot escape anywhere and cannot flow through the selection device anywhere.

[0270] Furthermore, it is preferred that the respective shape and / or dimensions of the at least one first and at least one second passage of the selection device correspond at least partially to the shape and / or dimensions of a first and / or second outlet of an inlet device of a multi-nozzle device. It is also possible that the shape and / or dimensions of the first passage of the selection device correspond to a first outlet of an inlet device of a multi-nozzle device and / or the shape and / or dimensions of the second passage of the selection device correspond to a second outlet of an inlet device of a multi-nozzle device. The first and second outlets may have different shapes and / or dimensions. A tenth aspect of the present invention comprises a multi-nozzle device for arrangement on a linkage or on at least one liquid line of an agricultural spreading machine.

[0271] It is expressly pointed out that the features of the selection device, as mentioned under the ninth aspect, can be used individually or in combination with each other in the multi-nozzle device.

[0272] A multi-nozzle device for arrangement on a boom or on at least one liquid line of an agricultural distribution machine, such as a field sprayer, comprises a selection device according to the ninth aspect.

[0273] Furthermore, the multi-nozzle device can include a conduit for conveying and / or guiding a first and / or a second liquid to a first and / or at least one second outlet device of the multi-nozzle device. This is described, for example, under the third aspect of the present invention.

[0274] Furthermore, the selection device can be arranged in a first rotary mounting of the piping system. Using the multi-nozzle device, it is possible to reduce the number of nozzles compared to prior art solutions, while maintaining the same number of application options. In other words, prior art solutions require a significantly higher number of nozzles to achieve the same flexibility as the presented multi-nozzle device. These nozzles must be attached to liquid lines and / or a rod of a distribution machine. Therefore, cost reductions in assembly and manufacturing can be expected.

[0275] An eleventh aspect of the present invention comprises a multi-nozzle device for arrangement on a boom or on at least one liquid line of an agricultural spreading machine. It is expressly pointed out that the features of the multi-nozzle devices mentioned in the second, fourth, sixth, eighth, and tenth aspects can be applied individually or in combination to the multi-nozzle device according to the eleventh aspect. Thus, a multi-nozzle device for arrangement on a boom or on at least one liquid line of an agricultural spreading machine, such as a field sprayer, can comprise an inlet device for receiving a first and / or a second liquid. The inlet device can include a first and / or second receiving unit and / or a clamping unit with a first and second clamping element.

[0276] Furthermore, the multi-nozzle device can include a conduit for conveying and / or guiding a first and / or a second liquid to a first and / or at least a second outlet device of the multi-nozzle device.

[0277] Furthermore, the multi-nozzle device can include a selection device for choosing and / or determining the dispensing of a first and / or second liquid from a first and / or at least one second outlet device of the multi-nozzle device. The selection device can be arranged between an inlet device of the multi-nozzle device and a piping device of the multi-nozzle device.

[0278] Furthermore, the multi-nozzle device can include a first outlet device and two second outlet devices, e.g. a left second outlet device and a right second outlet device, each for dispensing a first and / or a second liquid.

[0279] Furthermore, the multi-nozzle device can have two control devices for controlling the flow direction of a first and / or a second liquid to a first and / or two second outlet devices of the multi-nozzle device. The control devices can be located between the outlet devices and a piping device of the multi-nozzle device. It is also possible for an inlet device of the multi-nozzle device to be formed as a single unit together with a piping device of the multi-nozzle device. In this case, the multi-nozzle device can then do without a selection device or not have one at all.

[0280] The multi-nozzle device makes it possible to reduce the number of nozzles compared to prior art solutions, while maintaining the same number of application options. In other words, prior art solutions require a significantly higher number of nozzles to achieve the same flexibility as the presented multi-nozzle device. These nozzles must be attached to liquid lines and / or the boom of a distribution machine. Therefore, cost reductions in assembly and manufacturing can be expected.

[0281] A twelfth aspect of the present invention comprises an agricultural distribution machine.

[0282] It is expressly pointed out that the features of the multiple nozzle device, as mentioned under the eleventh aspect, can be used individually or in combination with each other in the distribution machine.

[0283] An agricultural spreading machine, such as a field sprayer, comprises a multi-nozzle device for mounting on a boom or on at least one liquid line of the agricultural spreading machine, as described in the eleventh aspect. Regarding all the aspects presented, it should be noted that the aforementioned designs allow for the highly flexible application of one or more liquids to a field and / or to plants. Thus, one or more liquids can be applied with high flexibility to a field and / or to plants.

[0284] Regarding all the aspects presented, it should be noted that the term "radial direction" can be understood as a direction that extends at a right angle away from, for example, a rotation axis of an imagined device.

[0285] Regarding all the aspects presented, it should be noted that the term "axial direction" can be understood as a direction that is oriented in the same direction or aligned in the same direction, such as the axis of rotation of a presented device.

[0286] Regarding all the aspects presented, it should be noted that the term "circumferential direction" can be understood as a direction that is aligned or oriented at a right angle to the radial direction and / or the axial direction.

[0287] Regarding all the aspects presented, it should be noted that the term "height" can be oriented in the same direction or aligned in the same direction as, for example, an axis of rotation or the axial direction of a presented device.

[0288] Furthermore, with regard to all aspects presented, it should be noted that the term "geometric center" can be understood as geometric center and / or geometric centroid.

[0327] Both figures show a multi-nozzle device 1 for arrangement on several, here two, liquid lines of an agricultural distribution machine, such as a field sprayer.

[0328] According to Figures 1 and 2, the multi-nozzle device 1 has an inlet device 2 for receiving a first and / or a second liquid, with a first and second receiving unit 3, 4 and with a clamping unit 15, 16, respectively, with a first clamping part 15 and a second clamping part 16. Furthermore, the multi-nozzle device 1 comprises a conduit device 17 for conveying and / or guiding a first and / or a second liquid to a first and / or at least one second outlet device 42, 43, 44 of the multi-nozzle device 1.

[0329] Furthermore, the multi-nozzle device 1 has a selection device 61 for determining the dispensing of a first and / or second liquid from a first and / or at least one second outlet device 42, 43, 44 of the multi-nozzle device 1. The selection device 61 is arranged between the inlet device 2 and the line device 17.

[0330] Furthermore, the multi-nozzle device 1 has a first outlet device 42 and two second outlet devices 43, 44 or a left, second outlet device 43 and a right, second outlet device 44, each for dispensing a first and / or a second liquid.

[0331] Furthermore, the multi-nozzle device 1 has two control devices 28, 29 for controlling the flow direction of a first and / or a second liquid to the first 42 and / or to the two second outlet devices 43, 44. The control devices 28, 29 are located between the outlet devices 42, 43, 44 and the piping device 17.

[0332] Figure 3 shows a spatial view of a multi-nozzle device 1 of an agricultural spreading machine according to a second embodiment, wherein Figure 4 shows an exploded view of the multi-nozzle device 1 from Figure 3.

[0333] Figures 3 and 4 show a similar structure of a multi-nozzle device 1 as shown in Figures 1 and 2, but with the difference that the multi-nozzle device 1 according to Figures 3 and 4 has only an inlet device 2 for receiving a first or second liquid with a single receiving unit 3 and with a clamping unit 15, 16 or with a first clamping part 15 and second clamping part 16.

[0334] Furthermore, in comparison of Figures 1, 2 with Figures 3, 4, the multiple nozzle device 1 according to the second embodiment does not include a selection device 61.

[0335] Furthermore, the entrance device 2 is designed as a single unit with the control device 17.

[0336] All further details can be found in the first embodiment shown in Figures 1 and 2.

[0337] More detailed explanations of the two briefly outlined examples follow in the description below.

[0338] Figure 5 shows a spatial view of an inlet device 2 for the multiple nozzle device 1 of an agricultural spreading machine according to the first embodiment from Figures 1 and 2.

[0339] Figure 6 shows a top view of the entrance device 2 from Figure 5, while Figure 7 shows a bottom view of the entrance device 2 from Figure 5.

[0340] Figure 8 shows a sectional view of the entrance device 2 from Figure 5.

[0341] For the sake of simplicity, Figures 5 to 8 are described together below. More precisely, Figures 5 to 8 show an inlet device 2 of a multi-nozzle device 1 of an agricultural spreading machine, such as a field sprayer, for receiving a first and / or a second liquid.

[0342] The inlet device 2 comprises a first receiving unit 3 for receiving a first liquid. The first receiving unit 3 can be connected to a first liquid line of an agricultural distribution machine and has an inlet 5 for a first liquid and an outlet 7 for a first liquid.

[0343] Furthermore, Figures 5 to 8 show that the inlet device 2 comprises a second receiving unit 4 for receiving a second liquid. The second receiving unit 4 can be connected to a second liquid line of an agricultural distribution machine and has an inlet 6 for a second liquid and two outlets 9, 10 for a first and / or second liquid.

[0344] Specifically, the second receiving unit 4 comprises a first outlet 9 for a second liquid and a second outlet 10 for a first liquid, in order to convey two different liquid flows. The second outlet 10 of the second receiving unit 4 is fluid-connected to the inlet 5 of the first receiving unit 3. Furthermore, Figures 5 to 8 show that the first and second receiving units 3, 4 are configured to convey a first and / or second liquid simultaneously or with a time delay and in any desired quantity.

[0345] As shown in Figure 7, the first and second outlets 9, 10 of the second receiving unit 4 are arranged coaxially and spaced apart from each other to allow two liquid flows, or a first and second liquid, to be conveyed separately. The first and second outlets 9, 10 are also arranged concentrically. The first outlet 9 surrounds or frames the second outlet 10.

[0346] It should be explicitly noted, however, that the first and second outputs 9, 10 of the second recording unit 4 can alternatively or additionally be arranged differently relative to each other, e.g., side by side and / or offset from each other. Furthermore, the second recording unit 4 can alternatively or additionally comprise more than two outputs, for example, three or four, which can be arranged at least partially concentrically, coaxially, and / or side by side.

[0347] Furthermore, Figures 7 and 8 show that the first outlet 9 of the second receiving unit 4 is formed in cross-section in the form of a hollow cylindrical recess, wherein the second outlet 10 of the second receiving unit 4 is formed in cross-section in the form of a cylindrical recess.

[0348] To put it another way, the first outlet 9 and the second outlet 10 are arranged and designed in such a way that both outlets 9, 10 have a pipe-in-pipe arrangement.

[0349] As shown in Figures 5 and 6, fluid can flow in at inlets 5 and 6 and out at outlets 7, 9, and 10. The fluid connection between inlet 5 and outlets 7 and 10 cannot be shut off. The same applies to inlet 6 and outlet 9.

[0350] As shown in Figures 5 and 8, the first receiving unit 3 has an inlet line 1 for a first liquid, wherein the inlet line 11 is oriented or aligned perpendicularly in a first plane. The first plane and a second plane are aligned or oriented at an angle to each other, e.g., 90 degrees.

[0351] Furthermore, as shown in Figures 5 and 8, the input 5 of the first receiving unit 3 is arranged at a first end of the input line 11. Conversely, the first output 7 of the first receiving unit 3 is arranged at a second end of the input line 11. The input line 11 of the first receiving unit 3 is hollow and cylindrical in shape.

[0352] As can be seen in Figures 5 and 6, the second receiving unit 4 includes an inlet line 14 for a second liquid, wherein the inlet line 14 is oriented or aligned perpendicularly in a first plane.

[0353] The inlet 6 of the second receiving unit 4 is arranged at a first end of the inlet line 14, while two outlets 9, 10 of the second receiving unit 4 are arranged at a second end of the inlet line 14 (see Figure 8). The inlet line 14 of the second receiving unit 4 is partially hollow cylindrical and partially forms part of a concentric double tube or part of a tube-in-tube arrangement. Furthermore, Figure 8 shows that the first receiving unit 3 has a fork 12 to divide a fluid flow, e.g., a first fluid, that can flow through the inlet line 11 of the first receiving unit 3.

[0354] The branch 12 is arranged between a first and second end of the input line 11 of the first receiving unit 3 or between the input 5 and the first output 7 of the first receiving unit 3.

[0355] Furthermore, Figure 8 shows that the fork 12 is designed to divert a fluid flow, e.g. of a first fluid, which can flow into the inlet line 11, at least partially into a connecting line 13 of the inlet device 2.

[0356] As mentioned, the inlet device 2 has a connecting line 13 for a first liquid to direct a liquid flow of a first liquid from the first receiving unit 3 towards the second receiving unit 4.

[0357] The connecting line 13 of the inlet device 2 is at least partially straight and horizontally oriented in a second plane. As already described, the first and second planes are aligned at an angle of, for example, 90 degrees to each other.

[0358] Furthermore, the connecting line 13 begins at or within the input line 11 of the first recording unit 3 and ends at or within the input line 14 of the second recording unit 4. In other words, the connecting line 13 begins between the first and second ends of the input line 11 of the first recording unit 3 and ends between the input 5 and the two outputs 9, 10 of the second recording unit 4.

[0359] The connecting line 13 is hollow cylindrical in shape. Furthermore, the ends of the connecting line 13 and the inlet line 14 of the second receiving unit 4, e.g. at the first and second outlets 9, 10 of the second receiving unit 4, are arranged concentrically and coaxially in order to convey two liquid flows, or a first and second liquid, separately from each other.

[0360] According to Figure 8, part of the connecting line 13 extends into the input line 14 of the second receiving unit 4, with the connecting line 13 forming with its first end part of the branch 12 of the first receiving unit 3 and with its second end the second output 10 of the second receiving unit 4.

[0361] Figure 11 shows a spatial view of a clamping unit 15, 16 of the input device 2 from Figure 5.

[0362] Accordingly, the inlet device 2 has a clamping unit 15, 16 with which the multi-nozzle device 1 can be attached to two fluid lines of an agricultural spreading machine. The clamping unit 15, 16 comprises a first clamping part 15 and a second clamping part 16, the first clamping part 15 being designed to clamp two fluid lines between itself and the second clamping part 16. The second clamping part 16 is designed to allow a fluid connection for a first fluid to the inlet 5 of the first receiving unit 3 and a fluid connection for a second fluid to the inlet 6 of the second receiving unit 4. Figure 9 shows a three-dimensional view of an inlet device 2 for the multi-nozzle device 1 of an agricultural spreading machine according to the second embodiment from Figures 3 and 4. Figure 10 shows a sectional view of the inlet device 2 from Figure 9.

[0363] More specifically, Figures 9 and 10 show an inlet device 2 for the multiple nozzle device 1 of an agricultural distribution machine, such as a field sprayer, and for receiving a first liquid.

[0364] The inlet device 2 has a first receiving unit 3 for receiving a first liquid, wherein the first receiving unit 3 can be connected to a first liquid line of an agricultural distribution machine. Furthermore, the first receiving unit 3 has an inlet 5 for a first liquid and two outlets 7, 8 for a first liquid. The first receiving unit 3 is configured to convey a first liquid in any quantity.

[0365] More precisely, the first receiving unit 3 has a first and a second outlet 7, 8 for a first liquid. The two outlets 7, 8 are oriented in opposite directions, so that a first liquid can be directed, conveyed, or transported in two different directions.

[0366] As can be seen in Figures 9 and 10, fluid can flow in at inlet 5 and out at outlets 7 and 8. The fluid connection between inlet 5 and outlets 7 and 8 cannot be shut off or interrupted.

[0367] Furthermore, Figures 9 and 10 show that the first receiving unit 3 has an inlet line 11 for a first liquid. The inlet line 11 is oriented or aligned perpendicularly in a first plane, with the first plane and a second plane being aligned at an angle to each other, e.g., 90 degrees.

[0368] At a first end of the input line 1 1, the input 5 of the first receiving unit 3 is arranged, whereas at a second end of the input line 11 a branch 12 of the first receiving unit 3 is arranged.

[0369] As indicated, the first receiving unit 3 has a fork 12 (see figure 10) to divide a fluid flow of a first fluid that can flow through the inlet line 11.

[0370] As shown in Figure 10, the branch 12 is designed to divide a fluid flow of a first liquid, which can flow into the inlet line 11, into equal parts. As already mentioned, the branch 12 is arranged between the inlet 5 and the two first outlets 7, 8 of the first receiving unit 3.

[0371] Furthermore, Figure 10 shows that the inlet line 11 is hollow cylindrical upstream of the junction 12. Figure 10 also shows that the line assembly 17 of the multi-nozzle device 1 is connected to the first and second outlets 7, 8 of the first receiving unit 3. Thus, the first receiving unit 3 and the line assembly 17 of the multi-nozzle device 1 are formed as a single unit, with the first outlet 7 being fluidly connected to a first transfer line 18 of the line assembly 17 of the multi-nozzle device 1 and the second outlet 8 being fluidly connected to a second transfer line 19 of the line assembly 17. Figure 12 shows a three-dimensional view of a clamping unit 15, 16 of the inlet device 2 from Figure 9.

[0372] As shown in Figure 12, the inlet device 2 has a clamping unit 15, 16 with which the multi-nozzle device 1 can be attached to a liquid line of an agricultural spreading machine. The clamping unit 15, 16 comprises a first clamping part 15 and a second clamping part 16, wherein the first clamping part 15 is configured to clamp a fluid line between itself and the second clamping part 16. The second clamping part 16 is configured to permit or establish a fluid connection for a first liquid to the inlet 5 of the first receiving unit 3 of the inlet device 2.

[0373] Figure 13 shows an upper, spatial view of the piping device 17 of the multiple nozzle device 1 according to the first embodiment from Figures 1 and 2.

[0374] Figure 14 shows a lower, spatial view of the conduit assembly 17 from Figure 13, Figure 15 shows a sectional view of the conduit assembly 17 from Figure 13, and Figure 16 shows a bottom view of the inlet assembly 2 from Figure 13.

[0375] For the sake of simplicity, figures 13 to 16 are described together below.

[0376] The figures shown above depict a conduit 17 of the multi-nozzle device 1 for conduiting and / or guiding a first and a second liquid to a first and to two second outlet devices 42, 43, 44 of the multi-nozzle device 1.

[0377] In this case, the line assembly 17 has a first and a second transfer line 18, 19 for transferring a first liquid and a second liquid from the inlet assembly 2 (not shown) of the multi-nozzle device 1 to a control unit 28, 29 (not shown) of the multi-nozzle device 1.

[0378] According to Figures 13 and 15, the first transfer line 18 can be connected via fluid communication to the input device 2 of the multiple nozzle device 1 or to the input line 11 of the first receiving unit 3 of the input device 2 (see also Figures 1 and 2).

[0379] Furthermore, the second transfer line 19 can be connected via fluid communication to the inlet device 2 of the multi-nozzle device 1 or to the inlet line 14 of the second receiving unit 4 of the inlet device 2 (see also Figures 1 and 2). The second transfer line 19 can also be connected via fluid communication to the connecting line 13 of the inlet device 2.

[0380] When looking together at Figures 1, 2 with 13 to 16, it can be seen that the piping device 17 is set up and designed to distribute a first and second liquid to a first 42 and / or to a second outlet device 43, 44 of the multiple nozzle device 1.

[0381] In more detail, the conduit assembly 17 is designed and configured to distribute or direct a first and second liquid to the first outlet 42 of the multi-nozzle device 1 and to two control units 28, 29 of the multi-nozzle device 1. The conduit assembly 17 and its transfer lines 18, 19 are designed and arranged such that a first and second liquid, e.g., from the interior of the conduit assembly 17, can be directed or guided to an exterior surface of the conduit assembly 17, e.g., for delivery to a control unit 28, 29 of the multi-nozzle device 1. Furthermore, Figure 15, in conjunction with Figures 1, 2, and 7, shows that the first transfer line 18 can be fluidly connected at its first end to the first outlet 7 of the first receiving unit 3 of the input device 2.

[0382] The second transfer line 19 can be fluidly connected at its first end to the first output 9 of the second receiving unit 4 of the input device 2. Furthermore, as shown in Figure 15, the second transfer line 18 can be fluidly connected at its first end to the second output 10 of the second receiving unit 4 of the input device 2 (see Figures 1, 2, 7 and 15). With reference to Figures 14, 15 and Figures 1, 2, the first and second transfer lines 18, 19 can each be fluidly connected at their second end to a control unit 28, 29 of the multi-nozzle device 1.

[0383] Furthermore, it can be seen from Figure 15 that the first and second transfer lines 18, 19 are designed such that a first and / or second liquid can be conveyed from an inlet 20A, 20B, 20C to an outlet 21A, 21B of the conduit system 17.

[0384] Specifically, the line assembly 17 has at least one inlet 20A, 20B, 20C per transfer line 18, 19 to receive a first and / or second liquid from the inlet assembly 2.

[0385] The inlets 20A, 20B, 20C are formed from an upstream, first end of the first or second transfer line 18, 19.

[0386] More precisely, a first inlet 20A of the line assembly 17 for receiving a first liquid can be connected fluid-communicatingly to the first outlet 7 of the first receiving unit 3 of the input assembly 2 (see Figures 7, 15 and 1, 2).

[0387] In addition, a second inlet 20B of the line assembly 17 for receiving a second liquid can be fluidly connected to the first outlet 9 of the second receiving unit 4 of the input unit 2 (see Figures 7, 15 and 1, 2).

[0388] Furthermore, a third inlet 20C of the line assembly 17 for receiving a first liquid can be connected fluid-communicatingly to the second outlet 10 of the second receiving unit 4 of the input assembly 2 (see Figures 7, 15 and 1, 2).

[0389] As already mentioned, according to Figure 15, the piping device 17 has a drain 21 A, 21 B for each transfer line 18, 19 to direct a first and / or a second liquid to the control device 28, 29 of the multi-nozzle device 1. Each drain 21 A, 21 B is formed from a downstream, second end of the first or second transfer line 18, 19, respectively.

[0390] To describe in more detail, a first flow 21 A of the line assembly 17 is formed from a downstream, second end of the first transfer line 18, whereas a second flow 21 B of the line assembly 17 is formed from a downstream, second end of the second transfer line 19.

[0391] The first outlet 21A for dispensing a first liquid is fluidly communicable with the control unit 28 of the multi-nozzle device 1 (see also Figures 1, 2), while the second outlet 21B for dispensing a first and / or second liquid is fluidly communicable with a further control unit 29 of the multi-nozzle device 1 (see also Figures 1, 2). As shown in Figures 14 and 15, the piping assembly 17 has transfer lines 18, 19 inside, each transfer line 18, 19 comprising two sections. The two sections are each straight and arranged at an angle to each other. However, while the section with inlets 20A, 20B, 20C comprises a hollow cylindrical channel, the other section with outlets 21A, 21B forms a channel in the form of a hollow cylindrical recess or part of a concentric double tube or part of a tube-in-tube arrangement.

[0392] Furthermore, Figure 15 shows that the conduit assembly 17 has a first and second transfer line 22, 23 for transferring a first and / or a second liquid to the first outlet unit 42 of the multi-nozzle device 1. The first and second transfer lines 22 are fluid-communicating with the first outlet unit 42 (see Figures 7, 15 and Figures 1, 2). In addition, the first and second transfer lines 22, 23 are each fluid-communicating with a control unit 28, 29 of the multi-nozzle device 1.

[0393] As can be seen in Figures 13 to 16, the first and second transfer lines 22, 23 and the first and second transfer lines 18, 19 are arranged coaxially and concentrically, at least in some sections. In other words, the first and second transfer lines 22, 23 and the first and second transfer lines 18, 19 are arranged and configured relative to each other such that both lines 18, 19; 22, 23 have or form a pipe-in-pipe arrangement, at least in some sections.

[0394] The first and second transfer lines 22, 23 and the first and second transfer lines 18, 19 are arranged and designed in such a way that a direct flow of a first or second fluid from a transfer line 18, 19 into a transfer line 22, 23 is prevented. Consequently, fluid communication between the first and second transfer lines 22, 23 and the first and second transfer lines 18, 19 is impossible, e.g., without the corresponding control device 28, 29 of the multi-nozzle device 1.

[0395] Thus, the conduit assembly 17 or its transfer lines 22, 23 are designed to receive a first or second liquid from a control unit 28, 29 of the multi-nozzle device 1 and to direct it to the first output unit 42 by directing or guiding the liquid to and within the conduit assembly 17.

[0396] Accordingly, the conduit assembly 17 and its transfer lines 22, 23 are designed and arranged as shown in Figures 13 to 16 such that a first or second liquid, e.g., from an outside of the conduit assembly 17, to an interior of the conduit assembly 17, e.g., for delivery to the first outlet assembly 42 of the multi-nozzle device 1, can be conveyed or guided. As already indicated, the conduit assembly 17 has the transfer lines 22, 23 inside it, with the first and second transfer lines 22, 23 each being straight.

[0397] In this arrangement, a first end of each transfer line 22, 23 forms an inflow 24, 25 and a second end of each transfer line 22, 23 forms an outflow 26, 27, whereby a first or second liquid can flow from the inflow 24, 25 to the outflow 26, 27 (see Figures 14 and 16).

[0398] The transfer lines 18, 19 and transfer lines 22, 23 of the line assembly 17 form a 90-degree angle with the input line 11 of the first receiving unit 3 of the input assembly 2 and with the input line 14 of the second receiving unit 4 of the input assembly 2 (see Figures 7, 15 and Figures 1, 2).

[0399] Furthermore, as already mentioned, the conduit assembly 17 according to Figures 13 to 16 has a first and second inlet 24, 25 to receive a first and / or second liquid from the control unit 28, 29 of the multi-nozzle device 1 and to direct it to the first outlet unit 42 of the multi-nozzle device 1.

[0400] In this process, the first and second inflows 24, 25 are formed from the upstream end of each transfer line 22, 23 of the conduit system 17.

[0401] As further shown in Figures 13 to 15, the first and second outlets 21 A, 21 B of the piping system 17 and the first and second inlets 24, 25 are arranged coaxially and concentrically. The first and second outlets 21 A, 21 B and the first and second inlets 24, 25 are arranged and configured relative to each other such that the outlets 20, 21 and the inlets 24, 25 form a pipe-in-pipe arrangement.

[0402] Furthermore, Figures 14 and 16 show that the conduit assembly 17 has a first and second outlet 26, 27 to direct a first and / or second liquid to the first outlet assembly 42 of the multiple nozzle assembly 1.

[0403] Furthermore, it should be noted that the conduit assembly 17 has a cylindrical recess at its geometric center, which allows a rotationally fixed connection between the first output device 42 and the selector device 61. Figure 15 also shows that the transfer lines 22, 23 of the conduit assembly 17 are fluidly connected to the cylindrical recess of the conduit assembly 17. This allows a gate valve 39 of a directional control valve unit 40 of a control device 28, 29, which can be arranged within a transfer line 22, 23, to bear against a displacement unit of the output device 42, which can be arranged in the cylindrical recess of the conduit assembly 17.

[0404] Furthermore, according to Figure 14, the line assembly 17 has a first rotary mounting 47 for the first output assembly 42, in which a rotary table unit 51 of the first output assembly 42 can be rotatably arranged.

[0405] The first rotary mounting 47 is designed in the form of a cylindrical recess and has detent points 57 on its inner surface or on its inside, into which a spring arm 56 of a rotary table unit 51 of the first output device 42 of the multi-nozzle device 1 can be engaged. This allows a detent position of the first output device 42 relative to the line assembly 17 to be predefined.

[0406] Figure 13 shows that the piping device 17 has a second rotary mount 49 for the selection device 61 of the multi-nozzle device 1 and for determining the dispensing of a first and / or second liquid from the first and / or one of the second outlet devices 42, 43, 44 of the multi-nozzle device 1. The second rotary mount 49 is also designed in the form of a cylindrical recess.

[0407] Referring to Figures 13 and 14, it can be seen that the first and second outlets 26, 27 are arranged on a first side of the piping assembly 17, and the inlets 20A, 20B, 20C of the piping assembly 17 are arranged on a second side of the piping assembly 17. The first and second sides are opposite each other and oriented outwards. Furthermore, Figures 13 to 16 show that the piping assembly 17 is formed in one piece.

[0408] Regarding Figure 10, it should be noted that a combination of a piping device 17 with an inlet device 2 for receiving a first and / or a second liquid into the multi-nozzle device 1 is shown. This combination is formed in one piece.

[0409] To avoid unnecessary repetition, it is pointed out that the explanations relating to Figures 13 to 16 for the piping device 17 of the multiple nozzle device 1 of an agricultural spreading machine according to the first embodiment apply analogously to the piping device 17 of the multiple nozzle device 1 of an agricultural spreading machine according to the second embodiment according to Figure 10.

[0410] The difference between Figures 13 to 16 and Figure 10 is that in Figure 10 only a liquid can be conveyed using the conduit device 17.

[0411] Nevertheless, the explanations concerning the line assembly 17 and its first and a second transfer line 18, 19 for the transfer of a first liquid and / or a second liquid from the inlet assembly 2 of the multi-nozzle device 1 to a control unit 28, 29 of the multi-nozzle device 1 also apply.

[0412] The same applies to the processes 21 A, 21 B of the pipeline 17, as well as to the first and second transfer lines 22, 23 and their inflows 24, 25 and outflows 26, 27. Inflows 20A, 20B, 20C do not exist.

[0413] A notable difference between Figures 13 to 16 and Figure 10, or between the first and second embodiments, is that the piping device 17 does not have a second rotary mount 49 for a selection device 61 of the multiple nozzle device 1.

[0414] Another difference is that the transfer lines 18, 19 only have one section that is straight.

[0415] Figure 17 shows a spatial view of the multiple nozzle device 1 of an agricultural spreading machine according to the first embodiment from Figures 1 and 2. Figure 18 shows a spatial view of the piping device 17, the first and a second outlet device 42, 44 and the control device 29 of the multiple nozzle device 1 from Figure 17.

[0416] Figure 19 shows a three-dimensional view of the first and second output devices 42, 44 and the control device 29 of the multi-nozzle device 1 from Figure 18, whereas Figure 20A shows a three-dimensional view of the first output device and the control device 29 of the multi-nozzle device 1 from Figure 18. Figure 20B shows a sectional view of the first output device and the control device 29 of the multi-nozzle device 1 from Figure 18.

[0417] For the sake of simplicity, the aforementioned figures 17 to 20B are described together below.

[0418] Figures 17 to 20B show a control device 28, 29 for controlling the flow direction of a first and / or a second liquid to the first 42 and / or to a second outlet device 43, 44 of the multi-nozzle device 1. The control device 29, which is described as an example for the two control devices 28, 29, has – as shown in the spatial view of a directional control valve unit 39 of the control device 29 from Figure 20A – a directional control valve unit 39 for the controlled discharge of a first and / or second liquid to the first 42 or to the second outlet device 44 of the multi-nozzle device 1.

[0419] The directional control valve unit 39 is designed according to Figures 17 to 20B to direct a fluid flow of a first and / or second fluid either to the second outlet device 44 or to the line device 17.

[0420] More specifically, and described in the context of the preceding and following explanations, the directional control valve unit 39 is designed to allow or block the flow of a first and / or second liquid either to a drain line 46 of an extension unit 45 of the second outlet device 44 or to the second transfer line 23 of the piping device 17.

[0421] Figure 26 shows a spatial view of the directional control valve unit 39 together with the adjoining first and second output devices 42, 44, while Figure 27 shows a further spatial view of the directional control valve unit 39 together with the adjoining first and second output devices 42, 44.

[0422] In light of Figures 26 and 27 as well as Figures 19 and 20B, it can be seen that the directional control valve unit 39 is designed to abut against the first outlet device 42 or against a displacement unit 53 of the first outlet device 42 in order to allow or block the flow of a first and / or second liquid to the second outlet device 44 or to the line device 17.

[0423] In this arrangement, as shown in Figure 17, a directional control valve unit 39 is arranged downstream of a valve unit 30 of the control device 28, 29.

[0424] According to Figures 20A, 20B, 21, 25 to 27, the directional control valve unit 39 has a gate valve 40 which allows or blocks the flow of a first and / or second liquid to the first or second outlet device 42, 44. The gate valve 40 is arranged within the second transfer line 22 of the piping device 17 (see Figures 18, 19, 20A, 20B, 21 with Figures 14, 15).

[0425] Furthermore, Figure 25 shows a spatial view of a gate valve 40 of the directional control valve unit 39 of the control device 29 from Figures 20A, 20B.

[0426] The gate valve 40 has a smaller outer diameter than the inner diameter of the second transfer line 23 of the line assembly 17, in order to allow a first and / or second liquid to flow to the first outlet assembly 42 of the multi-nozzle device 1.

[0427] According to Figure 25, the gate valve 40 has a shape similar to a cylinder head screw, with a head and a shaft whose diameter is smaller than that of the head. The shaft is arranged within the second transfer line 22, 23 of the piping assembly 17.

[0428] Furthermore, Figure 25 shows that the gate valve 40 is spring-loaded by a spring 41. Thus, one end of the gate valve 40 is designed to rest against a spring 41 of the directional control valve unit 39, and the other end of the gate valve 40 is designed to rest against a displacement unit 53 of the first output device 42 (see, for example, Figure 26).

[0429] Figure 25 also shows that the end of the gate valve 40, on which the spring 41 is arranged, has a larger diameter than the end of the gate valve 40 that can be arranged, or is arranged, on a displacement unit 53 of the first outlet device 42 (see Figures 26, 27). As already mentioned, the directional control valve unit 39 has the spring 41 with which the gate valve 40 can be biased in one direction. The spring 41 is biased such that a fluid flow of a first and / or second fluid to a drain line 46 of an extension unit 45 of the second outlet device 44 is permitted, and that a fluid flow of a first and / or second fluid to the second transfer line 23 of the piping device 17 is blocked.

[0430] Here, the spring 41 can be arranged or is arranged within a drain line 46 of an extension unit 45 of the second outlet device 44 - see Figures 26 and 27.

[0431] Furthermore, according to Figures 18 to 24, the control device 29 is set up and designed in such a way that two switching states, e.g. “open” and “closed” or continuously opening or continuously closing, can be realized with it.

[0432] For this purpose, the control device 29 or each control device 28, 29 has a valve 38 or a pulse width modulating valve 38, with which two switching states, e.g. "open" and "closed" or continuously opening or continuously closing, can be realized (see Figures 17 to 20B).

[0433] The valve 38 or the pulse width modulating valve 38 is positively and frictionally attached to a third connection 35 of a valve unit 30 of the control device 29.

[0434] Furthermore, the control device 28 or each control device 28, 29 has a valve unit 30 for flow control of a first and / or a second liquid to the first or to the second output device 42, 44.

[0435] Figures 22 to 24 show further spatial views of the valve unit 30 from Figure 21.

[0436] Thus, the valve unit 30 can be connected to the piping device 17 via fluid communication (see Figures 1, 2 and 17), whereby, with reference to Figures 18 to 20B, the valve unit 30 can be connected to the second transfer line 19 of the piping device 17 and to the second transfer line 23 of the piping device 17 via fluid communication, or, in combination, to Figures 1, 2 and 17, 18.

[0437] Furthermore, as can be seen in conjunction with Figures 1, 2 and 17, 18, the valve unit 30 can be fluid-communicatingly connected to the second outlet 21 B of the piping device 17, and the valve unit 30 can also be fluid-communicatingly connected to the second inlet 25 of the piping device 17 (see Figures 1, 2 and 15, 16, 17, 18).

[0438] According to Figure 18, the valve unit 30 can also be connected to the second output device 44 via fluid communication.

[0439] Furthermore, the valve unit 30 can be connected or is connected via fluid communication to a drain line 46 of an extension unit 45 of the second outlet device 44 (see Figures 26 and 27).

[0440] According to Figures 21 to 24, the valve unit 30 has a first connection 31 for connection to the piping device 17. The first connection 31 is designed to be complementary to the second transfer line 19 and to the second transfer line 23 of the piping device 17 in order to receive and discharge a first and / or second liquid.

[0441] Furthermore, the first connection 31 has a supply line 32 and a discharge line 33 for a first and / or second fluid, wherein the supply line 32 and the discharge line 33 are arranged coaxially and concentrically. In other words, the supply line 32 and the discharge line 33 are arranged and configured relative to each other such that the supply line 32 and the discharge line 33 have a pipe-in-pipe arrangement. Furthermore, the supply line 32 is fluid-communicating with the second transfer line 19 of the piping assembly 17, wherein the discharge line 33 is fluid-communicating with the second transfer line 23 of the piping assembly 17. A valve seat 36 of the valve unit 30 is arranged between the supply line 32 and the discharge line 33.

[0442] Furthermore, Figures 21 to 24 show that the valve unit 30 has a second connection 34 for connection to the piping assembly 17. The second connection 34 has several mounting options, e.g., in the form of holes, with which the valve unit 30 can be attached to the piping assembly 2 at different angles (see also Figures 17 and 18). The mounting options are arranged on a circle.

[0443] Furthermore, according to Figures 21 to 24, the valve unit 30 has a third connection 35 for connecting a valve 38 of the control device 29. A valve 38 of the control device 29 can be arranged at the third connection 35 in a friction-fit and form-fit manner, or as shown in Figures 17 to 20B.

[0444] Specifically, the third port 35 has a valve seat 36 at which a fluid flow of a first and / or second fluid through the valve unit 30 can be controlled by a valve 38 of the control device 29.

[0445] The valve seat 36 is located downstream of the supply line 32 of the first connection 31 of the valve unit 30 and upstream of the outlet 33 of the first connection 31 of the valve unit 30.

[0446] Furthermore, the valve seat 36 is designed such that a fluid flow of a first and / or second fluid can be allowed or prevented from a valve 38 of the control device 29.

[0447] When considering Figures 17 to 19, 21 to 24, and 13 and 14 together, the line 33 can be connected to the second transfer line 23 of the line assembly 17 via fluid communication. Furthermore, the line 33 can be connected to a drain line 46 of an extension unit 45 of the second output assembly 44 via fluid communication.

[0448] Furthermore, Figures 21 to 24 show that the valve unit 30 has a fourth port 37 for connection with the second output device 44 for the discharge of a first and / or a second liquid from the multiple nozzle device 1.

[0449] The fourth port 37 has a drain 33 for a first and / or second liquid, wherein the drain 33 of the fourth port 37 and the drain 33 of the first port 31 are configured as a single drain. A drain line 46 of an extension unit 45 of the second outlet device 44 can be fluidly connected to the fourth port 37, or is connected as shown in Figures 18 and 19.

[0450] For example, Figures 17 and 18 show that a valve unit 30 can be arranged or is arranged between a piping device 17 and a second output device 43, 44 of the multi-nozzle device 1.

[0451] Furthermore, Figures 19, 20A, 20B and 26, 27 show that the directional control valve unit 39 can be arranged, or is arranged, partially inside the valve unit 30, partially inside the piping assembly 17, and partially inside the second outlet assembly 43, 44. Figure 28A shows a first spatial view of the first outlet assembly 42 of the multi-nozzle device 1 of an agricultural spreading machine from Figures 1 and 2, with Figure 29 showing a second spatial view of the first outlet assembly 42 of the multi-nozzle device from Figure 28A.

[0452] More precisely, the aforementioned figures show the first output device 42 of a multi-nozzle device 1 for the output of a first and / or a second liquid.

[0453] The first output device 42 has a displacement unit 53 for controlling the control devices 28, 29 of the multi-nozzle device 1. The displacement unit 53 is designed and configured to displace at least a part of a control device 28, 29 of the multi-nozzle device 1 translationally.

[0454] More specifically, the displacement unit 53 is designed and configured to effect a translation of a part of each control device 28, 29 of the multi-nozzle device 1 by means of its rotation.

[0455] More specifically, the displacement unit 53 is designed and configured to displace the gate valves 40 of the directional control valve units 39 of the control devices 28, 29 translationally. As shown in Figures 17 and 19, the displacement unit 53 is even designed and configured to abut against one end of the gate valves 40 of the directional control valve unit 39 and to move the gate valves 40 translationally.

[0456] According to Figure 28A, the displacement unit 53 has a cylindrical shape, the base of which deviates from a circular surface and whose height extends in the axial direction A. The base has a geometric center.

[0457] Furthermore, the displacement unit 53 has an outer shape in which the edge of its outer shape has different distances to the geometric center of the displacement unit 53 or to the geometric center of the first output device 42.

[0458] Furthermore, the displacement unit 53 or the output device 42 is rotatable about its geometric center or about the geometric center of the first output device 42.

[0459] According to Figures 28A and 29 and also according to Figure 27, the sliding unit 53 has two recesses in the radial direction R or in its outer surface.

[0460] The displacement unit 53 and the output device 42 are designed to rotate about the axis of rotation D of the first output device 42. The axis of rotation D of the first output device 42 is also located at the geometric center of the displacement unit 53 and at the geometric center of the first output device 42.

[0461] Furthermore, Figures 28A and 29 show that the displacement unit 53 is arranged on a rotary table unit 51 of the first output device 42 and rises from or projects out of a plane of the rotary table unit 51 in axial direction A.

[0462] Furthermore, the first outlet device 42, as shown in Figures 28A and 29, has a rotary connection 60 to transmit rotation of the outlet device 42 to the selection device 61 of the multi-nozzle device 1, which is spaced axially A apart, for determining the dispensing of a first and / or second liquid from the first and / or from the second outlet devices 42, 43, 44 (see also Figures 1, 2). The rotary connection 60 is arranged on or attached to the displacement unit 53 and extends away from the displacement unit 53 and from a rotary table unit 51 of the outlet device 42.

[0463] Furthermore, Figures 28A and 29 show that the rotary connection 60 has three projections in the axial direction A, which are spaced apart from each other in the circumferential direction U. Thus, the selection device 61 of the multi-nozzle device 1 can engage between the two projections to determine the dispensing of a first and / or second liquid from the first and / or from one of the second outlet devices 42, 43, 44 in a torque-transmitting manner.

[0464] The three projections extend along the height of the displacement unit 53 and in the axial direction A of the output device 42.

[0465] In other words, the rotary connection 60, or rather its three projections, is designed similarly to the claw of a claw coupling or similarly to the coupling part of a claw coupling, in order to engage, or be able to engage, a geometrically adapted counterpart of a selection device 61 of the multi-nozzle device 1. The three projections are arranged geometrically such that they form a coded plug connection, in which correspondingly geometrically coded counterparts of the first output device 42 of the multi-nozzle device 1 and the selection device 61 engage, or are able to engage, with each other. In this way, only one type of connection is possible, thus preventing incorrect assembly.

[0466] As already indicated and as shown in Figures 28A and 29, the first output device 42 has a rotary table unit 51 for rotatable mounting in the first rotary mount 49 of the line device 17.

[0467] The rotary table unit 51 can be rotatably arranged in the first rotary mount 49 of the line assembly 17 and is designed in a disc-shaped or cylindrical form. Furthermore, the first output unit 42 or its rotary table unit 51 has a rotationally symmetrical shape.

[0468] The displacement unit 53 and several nozzle carriers 48 of the first output device 42 are arranged on opposite sides of the rotary table unit 51.

[0469] As can be seen in Figure 29, the rotary table unit 51 has several passages 52 which carry a first and / or second liquid from the piping device 17 to nozzle carriers 48 of the outlet device 42. The passages 52 are equidistant from each other in the circumferential direction U of the outlet device 42.

[0470] Furthermore, the rotary table unit 51 is designed such that the passages 52 form a fluid connection with the outlets 26, 27 of the piping device 17. This allows a first and / or second liquid to be directed to the nozzle carriers 48 of the first outlet device 42.

[0471] Figures 28A and 29 also show that the rotary table unit 51 has several spring arms 56 for generating a force. The rotary table unit 51 has the spring arms 56 on its radially outer side in order to engage in detents 57 of the first rotary mount 49 of the line assembly 17. This allows for the predefinable detent and / or positioning of the output unit 42 relative to the line assembly 17. Each spring arm 56 is designed to generate a spring force in the radial direction R, with the spring arms 56 being arranged at equal intervals from each other in the circumferential direction U of the output unit 42.

[0472] As already explained, the first output device 42 has several nozzle carriers 48, to each of which at least one spray nozzle and / or nozzle cap can be detachably attached.

[0473] The nozzle carriers 48 and the displacement unit 53 are arranged on opposite sides of the rotary table unit 51 of the first output device 42, each nozzle carrier 48 being designed in a hollow cylindrical shape and projecting from the rotary table unit 51 or extending away from the rotary table unit 51 in axial and radial directions A, R.

[0474] Furthermore, Figures 28A and 29 show that the nozzle carriers 48 and the passages 52 of the rotary table unit 51 are fluidly connected to each other.

[0475] With reference to Figures 1, 2, 17 and 18, it can be seen that the first output device 42 can be connected to, or is connected to, the line device 17 via fluid communication. The first output device 42 can be arranged, or is arranged, downstream of the line device 17 and downstream of the control devices 28, 29.

[0476] Figure 28B shows a first spatial view of the first output device 42 of the multiple nozzle device 1 of an agricultural spreading machine from Figures 3 and 4.

[0477] In this respect, the explanations relating to Figures 18A and 29 apply analogously to Figure 28B, while avoiding unnecessary repetition, except that in the second embodiment according to Figures 3 and 4 the first output device 42 does not include a rotary connection 60.

[0478] Figure 30 shows a spatial view of a part of the second output devices 43, 44 of the multiple nozzle device 1 of an agricultural spreading machine, wherein Figures 31 and 32 show a spatial view of a further part of the second output devices 43, 44 of the multiple nozzle device 1 of an agricultural spreading machine.

[0479] Figures 30 to 32 thus show a second output device 43 or 44 for the multiple nozzle device 1 and for the output of a first and / or a second liquid.

[0480] The second output device 43 or the second output device 44 each has a rotary table unit 54 for rotatable mounting in a second rotary mount 47 of an extension unit 45 of the second output device 43, 44. The rotary table unit 54 can be rotatably arranged in a second rotary mount 47 of an extension unit 45 of the second output device 43, 44.

[0481] Figure 30 shows that the rotary table unit 54 is disc-shaped or cylindrical and has a rotationally symmetrical shape.

[0482] Furthermore, Figure 30 shows that the rotary table unit 54 has several passages 55 which carry a first and / or second liquid from the piping device 17 via an extension unit 45 of the second outlet device 43, 44 to nozzle carriers 50 of the outlet device 43, 44.

[0483] The passages 55 are arranged at equal intervals to each other in the circumferential direction U of the output device 43, 44.

[0484] Furthermore, the rotary table unit 54 is designed such that each passage 52 forms a fluid connection with a drain 26, 27 of the piping unit 17 in order to direct a first and / or a second liquid to the nozzle carriers 50 of the second outlet unit 43, 44. In addition, the rotary table unit 54 is designed such that each passage 55 forms a fluid connection with a drain line 46 of an extension unit 45 of the second outlet unit 43, 44 in order to direct a first and / or a second liquid to nozzle carriers 50 of the outlet unit 43, 44.

[0485] Furthermore, Figure 30 shows that the rotary table unit 54 has several spring arms 58 to generate a force on its radially outer side in order to engage in detents 57, 59 of the first rotary mount

[0486] 49 of the line assembly 17 or to engage in detent points 59 in a second rotary mount 47 of an extension unit 45 of the second output assembly 43, 44. This allows for the predefinable locking and / or positioning of the output assembly 43, 44 relative to an extension unit 45 of the second output assembly 43, 44.

[0487] The spring arms 58 are thus designed to generate a spring force in the radial direction R, wherein the spring arms 58 are arranged equidistant from each other in the circumferential direction U of the output device 43, 44.

[0488] Furthermore, according to Figure 30, the second output device 43, 44 has several nozzle carriers 50, to each of which a spray nozzle can be detachably attached.

[0489] Each nozzle carrier 50 is hollow cylindrical and projects from the rotary table unit 54 or extends from the rotary table unit 54 in axial direction A and radial direction R. Furthermore, each nozzle carrier 50 and a passage 55 of the rotary table unit 54 of the output device 43, 44 are fluidly connected to each other.

[0490] According to Figures 1, 2, 17 and 18, the second output device 43, 44 or the second output devices 43, 44 can be connected or are connected to the line device 17 via fluid communication.

[0491] The second output devices 43, 44 can be arranged or are arranged downstream of the line device 17 and downstream of the control devices 28, 29.

[0492] According to Figures 27, 31 and 32, the second output device 43, 44 has an extension unit 45 for relocating the second output device 43, 44 away from the first output device 42 (see Figures 1, 2, 17 and 18).

[0493] According to Figures 31 and 32, the extension unit 45 has a drain line 46, to which a second rotary mount 47 of the extension unit 45 is connected.

[0494] Furthermore, the extension unit 45 has a second rotary mounting 47 for the rotary table unit 54 of the second output device 43, 44, in which the rotary table unit 51 can be rotatably arranged.

[0495] The drain line 46 and a fourth connection 37 of the valve unit 30 of the control device 28, 29 are matched and identically designed to ensure and / or guide a fluid flow.

[0496] Furthermore, the drain line 46 and a connecting transfer line 22, 23 of the piping assembly 17 extend in opposite directions (see Figures 14, 15 and 18), with the drain line 46 and a transfer line 22, 23 of the piping assembly 17 having the same volume. Figure 33 shows a first spatial view of the selection device 61 of the multi-nozzle device 1, with Figure 34 showing a second spatial view of the selection device 61 from Figure 33. Figure 35 shows a spatial view of the multi-nozzle device 1.

[0497] Figures 36 to 38 show exploded views of the multiple nozzle device 1 from Figure 35, however, according to Figure 36 in a first rotational state, according to Figure 37 in a second rotational state and according to Figure 38 in a third rotational state.

[0498] For the sake of simplicity, figures 33 to 388 are described together below.

[0499] The figures shown show a selection device 61 for selecting and / or determining the discharge of a first and / or second liquid from the first and two second output devices 42, 43, 44 of the multiple nozzle device 1.

[0500] The selection device 61 has a disc-shaped or cylindrical base body 61 A with two opposing, axially spaced end faces.

[0501] Furthermore, the selector device 61 includes a rotary connection 62 for torque transmission to the rotary connection 60 of the first output device 42, in order to accommodate a rotation from the output device 42 of the multiple nozzle device 1, which is spaced axially A apart (see Figures 1, 2, 33 and 34). In other words, the rotary connection 62 is configured to engage with the rotary connection 60 of the first output device 42, such that a rotation of the output device 42 causes a rotation of the selector device 61.

[0502] According to Figures 33 and 34, the rotary connection 62 is arranged centrally in the base body 61 A and centrally in the end faces of the base body 61A.

[0503] Furthermore, the rotary connection 62 has a first cylindrical recess 63A which penetrates the base body 61 A to three quarters of the height of the base body 61 A in axial direction A.

[0504] Furthermore, Figures 33 and 34 show that the rotary connection 62 includes a second cylindrical recess 63B, which penetrates the base body 61A to one-quarter of its height in the axial direction A. The first cylindrical recess 63A has a larger diameter than the second cylindrical recess 63B.

[0505] In total, the first and second cylindrical recesses 63A, 63B completely penetrate the base body 61A.

[0506] Within the base body 61 A, the transition from the first to the second recess 63A, 63B forms a stop 64 in the axial direction A for the rotary connection 60 of the first output device 42. Furthermore, Figure 33 shows that the rotary connection 62 has three projections 65, which are spaced apart from each other in the circumferential direction U, so that the first output device 42 of the multi-nozzle device 1, e.g. with its rotary connection 60, can engage between the three projections 65 (see, e.g., Figures 1, 2, 36 to 38).

[0507] The three projections 65 are designed similarly to the claw of a claw coupling or similarly to the coupling part of a claw coupling in order to engage, or be able to engage, a geometrically adapted counterpart of the first output device 42 of the multi-nozzle device 1. The three projections 65 are arranged geometrically such that they form a coded plug connection in which correspondingly geometrically coded counterparts of the first output device 42 and the selector device 61 engage, or are able to engage, with each other. In this way, only one type of connection is possible, thus preventing incorrect assembly. As shown in Figure 33, the three projections 65 are cuboid in shape and project radially inwards from the edge or the cylindrical surface of the first cylindrical recess 63A of the rotary connection 62.

[0508] Furthermore, the three projections 65 at the transition between the first and second cylindrical recesses 63A, 63B project from the second cylindrical recess 63B in axial direction A. Thus, the three projections 65 project from the stop 64 in axial direction A and in the direction of an end face of the base body 61A, or extend along the height of the base body 61A.

[0509] The three projections 65 extend beyond one of the two end faces of the base body 61A in axial direction A.

[0510] Furthermore, Figures 33 and 34 show that the selection device 61 has several first passages 66 and one second passage 67 for the flow of a first and / or second liquid, wherein the first and second passages 66, 67 are shaped differently or have different cross-sectional shapes.

[0511] It is provided that one or more first passes 66 are assigned to a first liquid and that one or more second passes 67 are assigned to a second liquid. In other words, the one or more first passes 66 can be configured to pass through a first liquid and / or the one or more second passes 67 can be configured to pass through a second liquid.

[0512] The first passages 66 are designed as bores or in the form of cylindrical recesses. In contrast, the second passage 67 has a horseshoe-shaped, crescent-shaped, or slot-shaped cross-section, or is designed as a recess with a general cylindrical shape, the curved course of which within a plane forms a horseshoe and / or a crescent. Furthermore, the first passages 66 and the second passage 67 have the same flow cross-sections. In this way, equal flow rates or volume flows of a first and / or second liquid can flow through the corresponding passages 66 and 67.

[0513] The first passages 66 and the second passage 67 are arranged within the base body 61 A and within the end faces in such a way that by rotating the selection device 61 it is possible to selectively ensure a flow through either two first passages 66 or one first passage 66 and the second passage 67.

[0514] The first passages 66 and the second passage 67 are spaced apart from each other in the circumferential direction U of the voting device 61.

[0515] Furthermore, the first passages 66, or rather their geometric centers, and the second passage 67, or rather its geometric center, are equidistant from the rotary terminal 62 of the selector device 61. Thus, the first passages 66 and the second passage 67, with their geometric centers, are arranged on a common circle or radius extending from the rotary terminal 62. Referring to Figures 1, 2, and 35 to 39, it is noticeable that the selector device 61 is located downstream of the input device 2 and upstream of the line device 17. In other words, the selector device 61 is located between the input device 2 and the line device 17. The selector device 61 and the first output device 42 are rotatably connected to each other and are fixedly connected to each other, such that a rotation of the output device 42 causes a rotation of the selector device 61.

[0516] As already mentioned, figures 36 to 38 show several rotation states of the selection device 61.

[0517] In a first rotational state of the selector device 61, it is permeable to both a first and a second liquid. In a second rotational state of the selector device 61, it is permeable to only the first liquid. In a third rotational state of the selector device 61, it is permeable to both the first and second liquid.

[0518] More precisely, in the first rotational state of the selector device 61, a first liquid can flow from the inlet device 2 to the first outlet device 42. Simultaneously, in the first rotational state of the selector device 61, a second liquid can flow from the inlet device 2 to the first outlet device 42.

[0519] As a result, the first and second liquids can be dispensed from the first output device 42.

[0520] It is also possible to design the selection device 61 in conjunction with the first output device 42 or with its displacement unit 53 in such a way that in the first rotational state of the selection device 61 a first liquid can flow from the input device 2 to the second output device 43 and a second liquid can flow from the input device 2 to the further second output device 44.

[0521] Furthermore, in the first rotational state of the selector device 61, a first passage 66 of the selector device 61, a first outlet 7 of the first input unit 3 of the input device 2, and a passage 52 of the rotary table unit 51 of the first output device 42 are part of a common fluid connection. Thus, a first fluid can enter at the input device 2 and exit at a nozzle carrier 48 of the first output device 42.

[0522] Furthermore, in the first rotational state of the selector device 61, the second passage 67 of the selector device 61, the first outlet 9 of the second input unit 4 of the input device 2, and a passage 52 of the rotary table unit 51 of the first output device 42 are part of a common fluid connection. Consequently, a second fluid can enter the input device 2 and exit at a nozzle carrier 48 of the first output device 42.

[0523] Furthermore, according to Figure 37, in the second rotational state of the selection device 61 a first liquid can flow from the inlet device 2 of the multiple nozzle device 1 to two second outlet devices 43, 44 of the multiple nozzle device 1.

[0524] More specifically, in the second rotational state of the selector device 61, a first passage 66 of the selector device 61, the first outlet 7 of the first input unit 3 of the input device 2, and a passage 55 of the rotary table unit 54 of the second output device 43 are part of a common fluid connection. Accordingly, a first fluid can enter at the input device 2 and exit at a nozzle carrier 50 of the second output device 43.

[0525] Furthermore, in the second rotational state of the selector device 61, a first passage 66 of the selector device 61, the second outlet 10 of the second input unit 4 of the input device 2, and a passage 55 of the rotary table unit 54 of the second output device 44 are part of a common fluid connection. Thus, a first fluid can enter at the input device 2 and exit at a nozzle carrier 50 of the second output device 44 of a multi-nozzle device 1.

[0526] As a result, a first liquid can flow into the multiple nozzle device 1 at the inlet device 2 and be discharged from the left, second outlet device 43 and from the right, second outlet device 44.

[0527] Furthermore, in the second rotational state of the selection device 61, a fluid connection through or via the selection device 61 can be prevented, so that a second fluid can enter at the inlet device 2 or at the second inlet unit 4 of the inlet device 2 but cannot escape anywhere and cannot flow through the selection device 61 anywhere.

[0528] In the third rotational state of the selection device 61 according to Figure 38, neither a first nor a second liquid can flow from the inlet device 2 of the multiple nozzle device 1 to the first and / or second outlet device 42, 43, 44 of the multiple nozzle device 1.

[0529] Thus, in the third rotational state of the selection device 61, a fluid connection through or via the selection device 61 can be prevented, so that a first fluid can enter at the inlet device 2 or at the first inlet unit 3 of the inlet device 2, but cannot escape anywhere and cannot flow through the selection device 61 anywhere.

[0530] Furthermore, in the third rotation state of the selection device 61, a fluid connection through or via the selection device 61 can also be prevented, so that a second fluid can enter at the inlet device 2 or at the second inlet unit 4 of the inlet device 2, but cannot escape anywhere and cannot flow through the selection device 61 anywhere.

[0531] The above explanations regarding the states of rotation apply analogously to the second embodiment according to Figures 3 and 4. However, in this case, the states of rotation – simplified – do not refer to the selection device 61 and the first output device 42, but only to the first output device 42, since the second embodiment does not have a selection device 61.
