Description

[0001] Agricultural distribution machine for spreading material and method for operating an agricultural distribution machine

[0002] The invention relates to an agricultural distribution machine for spreading material according to the preamble of patent claim 1 and a method for operating an agricultural distribution machine according to the preamble of patent claim 10.

[0003] In the field of agriculture, a multitude of variants of towed, mounted, and / or self-propelled work machines are known. These include, among others, distribution machines designed for spreading liquid and / or granular materials along agricultural land. Depending on the type of application, such distribution machines can be designed, for example, like sowing and / or fertilizing machines or as field sprayers. Depending on the type of distribution machine and / or application, the material to be distributed can be, for example, granular or bulk seed and / or fertilizer, or as a liquid spray, such as a pesticide or the like.

[0004] In agricultural practice, distribution machines are often required that are suitable for storing particularly large quantities and / or different types or varieties of distribution goods. Typically, distribution machines are used for this purpose that have at least one storage container unit, in particular with at least one storage container or at least one container chamber.

[0005] In numerous operating situations, it is necessary to know and / or determine the current quantity of the distribution material or a current quantity of distribution material that is held in the storage container unit in a specific situation. This can be necessary, for example, for fill level and / or consumption monitoring and / or for operating various working units of the distribution machine. From the document DE 102009 044 068 A1, a distribution machine with a storage container unit, in particular with at least one container chamber, is known, which comprises a plurality of detection means assigned to the storage container unit, in particular of the same type and / or designed in the manner of weighing sensors. The detection means are designed to detect the distribution material located in the storage container unit.

[0006] However, such distribution machines currently have the disadvantage that such detection devices can only determine the mass or fill weight of the distribution material located in and / or filled into the storage container unit. Due to the different types and / or varieties of distribution materials to be dispensed, which can differ in mass or fill weight depending on the volume, this can lead to a misinterpretation of the currently available distribution material quantity. Determining the fill volume and / or fill level, with varying distribution materials, has not yet been readily possible using such detection devices, especially not without additional fill level monitoring devices.

[0007] In a variety of situations, however, the detection of the distribution material could be further improved and / or simplified if, in addition to and / or instead of the mass or fill weight stored in the storage container unit, the stored volume or fill volume of the distribution material is known and / or monitored. This is particularly advantageous for filling processes of the distribution machine. The object underlying the invention is therefore to further improve and / or simplify the detection and / or determination of the stored distribution material on a distribution machine.

[0008] The object is achieved by a distribution machine of the type mentioned at the outset, wherein the distribution machine has an evaluation device which is designed to determine the density of the stored distribution material using the detection means and taking into account geometry and / or center of gravity information, in particular information which can be stored and / or retrieved electronically. As a result of this measure, the volume of the respective distribution materials held in the storage container unit can be determined in a particularly simple manner using common detection means, in particular of a similar type and / or arranged externally. In particular, this ensures that the volume of different distribution materials, which can vary between different distribution processes, can be determined. The detection means are preferably in the form of force- or load-detecting sensors, such as force sensors, strain gauges or the like., and is preferably arranged externally on the at least one storage container unit. Detection means which are designed in the manner of weighing sensors or load cells are particularly preferred. The detection means are each designed to transmit a sensor signal which is dependent on the quantity of material to be distributed to the evaluation device. The evaluation device is further designed to process the sensor signals accordingly and to take them into account to determine the density of the respective material to be distributed. The geometry and / or center of gravity information relating to the storage container unit can be specified by the manufacturer or alternatively or additionally by the user or operator and / or can be stored, in particular, on an electronic memory of the distribution machine and / or the evaluation device.

[0009] The evaluation device is preferably configured to determine and / or ascertain the respective density and thus the volume of the material to be distributed during a filling process of the storage container unit or during the filling of the material to be distributed. Alternatively or additionally, the evaluation device can be configured to determine and / or ascertain the respective density and / or the filling volume during operation, in particular during application (e.g., for fill level monitoring), or for the purpose of calibrating the control and / or regulating system, in particular sensor devices. The evaluation device can preferably be at least one computer unit of a control and / or regulating system assigned to the distribution machine. Alternatively or additionally, the evaluation device can also be part of a mobile and / or external operating and / or display device, such as a smartphone, operating terminal, notebook, farm computer, or the like.

[0010] The at least one storage container unit is preferably arranged on a frame of the distribution machine, with the detection means particularly preferably being arranged between the frame and the storage container unit. Alternatively, it would be conceivable for the detection means to be arranged exclusively on the frame or on the storage container.

[0011] Unless explicitly stated otherwise, the term "volume" hereinafter refers primarily to the volume of the material being distributed held and / or filled in the storage container unit. Alternatively or additionally, the term "volume" hereinafter may also refer to the fill level of the storage container unit, unless explicitly stated otherwise.

[0012] Furthermore, unless explicitly stated otherwise, the term "storage container unit" refers to a container or container chamber arranged on the distribution machine, which is intended for receiving and / or holding distribution material. Alternatively, the term "storage container unit" can also be understood as an assembly with several storage containers or container chambers arranged on the distribution machine, such as a multi-chamber container.

[0013] In a preferred embodiment of the distribution machine according to the invention, the respective current position and / or location of a container center of gravity on the distribution machine, which depends in particular on the quantity of material to be distributed and / or a fill volume, can be determined and / or specified on the basis of the geometry and / or center of gravity information. In this case, it is preferably provided that the respective container centers of gravity, in one of several preferred embodiment variants, represent the centers of gravity of an empty storage container unit, in particular when empty. In a particularly preferred embodiment variant, the respective container centers of gravity can represent the centers of gravity of the material to be distributed located in the storage container unit. In a further preferred embodiment variant, the container centers of gravity can also represent an overall center of gravity from the centers of gravity of the respective material to be distributed and the storage container unit.In particular, it is provided that, based on the geometry and / or center of gravity information, a plurality of positions and / or locations of the respective container centers of gravity can be specified, which are each assigned to different fill levels of the storage container unit. In other words, the position and / or location of the container center of gravity can have a different position and / or location when the storage container unit is full than, for example, when the storage container unit is half full. The geometry and / or center of gravity information can be implemented, for example, in the form of an electronically stored function curve and / or table, for example as a lookup table. Furthermore, the density and / or volume can be determined from a function and / or equation consisting of the geometry and / or center of gravity information and the sensor signals of the detection means.Furthermore, the geometry information can also electronically represent the shape and / or size of the storage container unit.

[0014] In a further development of the distribution machine according to the invention, the position and / or location of the respective container centers of gravity is stored in a manner associated with a fill volume, in particular a fill level of the storage container unit. The storage container unit has different positions and / or locations for the container center of gravity for different fill volumes, in particular fill levels. The different container centers of gravity, each associated with a different fill volume, in particular fill level, can be stored and / or determined using the geometry and / or center of gravity information. For example, the container center of gravity of a less filled storage container unit can be located further down in the vertical direction, while the container center of gravity of a fully filled storage container unit can be located further up in the vertical direction.

[0015] In another preferred embodiment of the distribution machine according to the invention, the evaluation device is configured to calculate the density of the distribution material based on a mass of the stored and / or filled distribution material, which can be determined by means of the detection means, preferably based on a force and / or moment equilibrium. The weight and / or force components relevant and / or considered for the calculation result in particular from the weight of the stored and / or filled distribution material. Based on these force components and / or the weight, defined sensor signals and / or sensor signal combinations result from the plurality of detection means, which can be uniquely identified by the evaluation device and uniquely assigned to determine the density and / or volume.This has the crucial advantage that no additional detection devices, especially those mounted on the inside of the storage container unit, are required to measure and / or determine the density and thus the volume. The density and thus the volume of the material being distributed can thus be determined particularly easily.

[0016] In an alternative but equally preferred embodiment, the force and / or moment equilibrium can alternatively or additionally be defined with respect to a specific point, in particular one of the container centers of gravity.

[0017] In another development of the distribution machine according to the invention, the storage container unit, in particular the storage container or the container chamber, is designed such that the positions and / or locations of the respective container centers of gravity differ in a lateral direction, preferably parallel and / or transverse to a direction of travel. Thus, the positions and / or locations of the container centers of gravity can be clearly stored and / or determined depending on the available fill volume of the material to be distributed and relative to a reference point on the distribution machine, in particular to a global coordinate system and / or to a coordinate system assigned to the distribution machine. Depending on the embodiment, the storage container unit can be designed such that the position and / or location of the container center of gravity changes with a changing fill level, parallel to the direction of travel and / or to a longitudinal axis of the storage container unit.Alternatively or additionally, the storage container unit can also be designed such that the position and / or location of the container's center of gravity changes with a changing fill level transverse to the direction of travel and / or the longitudinal axis of the storage container unit. In a further preferred embodiment of the distribution machine according to the invention, the storage container unit, in particular the storage container or the container chamber, is designed to be at least partially asymmetrical for this purpose.

[0018] In a further development of the distribution machine according to the invention, the storage container unit has a plurality of at least substantially vertical sections, wherein several or all of the vertical sections are differently inclined and / or oriented, in particular, in different spatial directions. In other words, the storage container unit is preferably designed such that the container centers of gravity of a first section are located or positioned along a first common plane, while the container centers of gravity of at least one further or different section are located or positioned along a further or different common plane.The first plane, which is assigned to the first section, can, for example, be aligned at least approximately perpendicularly and / or transversely to the direction of travel, while the further or other plane, which is assigned to the further or other section, can, for example, be aligned at least approximately parallel to the direction of travel.

[0019] Furthermore, a distribution machine according to the invention is preferred in which a target filling volume can be specified for the distribution machine, in particular for the evaluation device, preferably at the factory or and / or temporarily, before the distribution material is filled into the storage container unit. Reaching the target filling volume can particularly preferably be signaled visually and / or acoustically. The target filling volume can, for example, be the maximum and / or permissible usable volume of the storage container unit. Alternatively or additionally, it can also be provided that the target filling volume can be specified and / or entered by the manufacturer and / or user. In particular, a target filling volume can be provided that can be specified, preferably via an input means such as a display or the like. Thus, for example, the user can specify up to which fill level the storage container unit should and / or may be filled with the respective distribution material.Furthermore, the distribution machine is provided with means designed to visually and / or acoustically signal the reaching of the target filling volume, for example, during the filling process. Such means can, for example, be configured as one or more lighting devices, a display, and / or in the manner of one or more loudspeakers or the like.

[0020] In another preferred embodiment of the distribution machine according to the invention, the evaluation device is configured to determine the type and / or grade of the stored and / or filled distribution material based on the determinable density. The evaluation device is configured, in particular, to distinguish and / or detect different types and / or grades of distribution material based on the determinable density.

[0021] The object underlying the invention is further achieved by a method for operating the agricultural distribution machine of the type mentioned above, wherein an evaluation device is provided which is configured to determine the density of the stored distribution material based on the detection means and taking into account geometry and / or center of gravity information, in particular information that can be stored and / or retrieved electronically. Regarding the advantages and modifications of the method according to the invention, reference is first made to the advantages and modifications of the distribution machine according to the invention.

[0022] The material to be distributed is detected by means of several, preferably similar, detection means which are assigned to a storage container unit of the distribution machine.

[0023] The detection means are preferably designed to detect the mass, in particular the fill weight, of the distribution material, for example during and / or after a filling process and / or a dispensing process or during operation of the distribution machine. In a further development of the method according to the invention, the respective current position and / or location of a container center of gravity on the distribution machine, which position and / or location is dependent in particular on the quantity of distribution material and / or a fill volume, is determined and / or specified on the basis of the geometry and / or center of gravity information. In other words, the evaluation device is informed on the basis of the geometry and / or center of gravity information at which position and / or location a container center of gravity is to be expected for a defined quantity of distribution material held and / or a defined fill volume, in particular a defined fill level.The geometry and / or center of gravity information can in particular depict a plurality of positions and / or locations of a respective container center of gravity, since this changes depending on a currently held quantity of distribution material and / or a currently held filling volume, in particular depending on the fill level.

[0024] In a further preferred embodiment of the method according to the invention, a mass or weight or fill weight of the stored and / or filled distribution material is first detected and / or determined using the detection means. Preferably, the density of the distribution material is then determined and / or calculated based on the mass or weight and the stored and / or retrieved geometry and / or center of gravity information, in particular the container's center of gravity. In other words, when determining the density and thus the volume, the evaluation device takes into account both the sensor signals of the detection means and the specified and / or retrieved geometry and / or center of gravity information.

[0025] Furthermore, a method according to the invention is preferred in which a target fill volume is specified for the distribution machine, in particular the evaluation device, preferably at the factory and / or temporarily, before the distribution material is filled into the storage container unit. The manufacturer, user and / or operator of the distribution machine can thus, for example, specify a maximum and / or minimum fill volume for the distribution material. Reaching the target fill volume is then preferably signaled visually and / or acoustically. As soon as the fill level of the distribution material in the storage container reaches, falls below and / or exceeds the target fill volume, the evaluation device can signal this visually and / or acoustically. Furthermore, a notification, for example in the form of a text message or the like, on a mobile operating and / or display means would also be conceivable.Furthermore, it would be conceivable alternatively or additionally for external devices, such as filling stations, to be controlled automatically based on the specified target filling volume in order, for example, to stop the filling process when the maximum target filling volume is reached and / or exceeded.

[0026] In another preferred embodiment of the method according to the invention, the type and / or variety of the stored and / or filled distribution material is determined by the evaluation device based on the determined density. The evaluation device can thus clearly identify and / or classify the filled and / or stored distribution material based on the density. Alternatively or additionally, for example, in the case of seed as the distribution material, the thousand-seed weight can also be determined based on the density and / or the evaluation device.

[0027] Further details of the invention can be found in the example description and the drawings. The drawings show

[0032] Fig.3C shows the storage container unit from Fig.3A in a schematic view from the front.

[0033] The storage container unit 10 of an agricultural distribution machine 100, here for example a seed drill, is arranged on a frame 20. On the front of the frame 20, a drawbar 21 is arranged, which is to be arranged on a coupling device of an agricultural tractor, while the running wheels 22 are arranged on the rear of the frame 20. On the rear of the frame 20, a seed bar with seed coulters can be arranged in a manner not shown by means of a suitable coupling device. The storage container unit 10 has a storage container 11, which is referred to below as the container chamber. In other embodiments according to the invention, the storage container unit 10 can also be divided into several container chambers 11. The container chamber 11 of the storage container unit 10 is funnel-shaped in the lower region and has an outlet opening 111.A dosing element 112 is assigned to the outlet opening 111 for the metered and / or adjustable discharge of the distribution material located in the container chamber 11.

[0034] At this point, it should be explicitly mentioned again that the illustrated towed distribution machine 100, in an alternative embodiment, can also be carried by a tractor or attached and / or mounted to it. Furthermore, a self-propelled distribution machine 100 would also be conceivable as an alternative.

[0035] Depending on the application and / or design of the distribution machine 100, granular or bulk and / or liquid distribution material can be held and / or stored within the container chamber 11. The distribution material can, in particular, be embodied as seed, fertilizer, or pesticide, or the like. It is also conceivable that different types and / or varieties of distribution material are applied in different application processes and thus filled and / or stored in the storage container unit 10.

[0036] Furthermore, it can be seen that the container chamber 11 has a longitudinal axis A1, which is aligned and / or formed at least approximately corresponding to a direction of travel F of the distribution machine 100.

[0037] As can be seen more clearly in Fig. 1B, the storage container unit 100 is assigned detection means S1-S3, designed here as weighing sensors. Alternatively or additionally, other types of force-sensing sensors, such as strain gauges or the like, would also be conceivable. The detection means S1-S3 are arranged outside the storage container unit 10, with one of the detection means S1 being arranged in the front area and the other detection means S2, S3 being arranged in the rear area and laterally offset. By means of these detection means S1-S3, designed as weighing sensors, the goods to be distributed in the storage container unit 10 can be detected.

[0038] As can also be seen in the figures, an evaluation device 200 according to the invention is provided, which is assigned to the distribution machine 100 and is connected to the detection means S1-S3 in a signal-conducting manner. In this exemplary embodiment, the evaluation device 200 is connected to the detection means S1-S3 via signal lines 201, whereby alternatively or additionally a wireless connection between the evaluation device 200 and the detection means S1-S3 would also be conceivable. The evaluation device 200 is configured according to the invention to determine the density of the distribution material stored in the container chamber 11 based on the detection means S1-S3 and taking into account geometry and / or center of gravity information, in particular information that can be stored and / or retrieved electronically.The geometry and / or center of gravity information can be stored on and retrieved from an electronic data storage device assigned to the evaluation device 200.

[0039] Based on the geometry and / or center of gravity information, the evaluation device 200 can determine and / or specify the respective current position and / or location of a container center of gravity SW1A-SW1C on the distribution machine 100, which depends in particular on the quantity of material to be distributed and / or a filling volume.

[0040] The quantity of distribution material held in reserve is understood to mean the mass, in particular the fill weight, of the distribution material located in the container chamber 11. Alternatively or additionally, the quantity of distribution material held in reserve and / or the volume of the distribution material can also be understood as the fill level of the container chamber 11.

[0041] Since the position and / or location of the container center of gravity SW1A-SW1C of the container chamber 11 changes with decreasing and / or increasing quantity of distribution material or decreasing and / or increasing volume, a plurality of container center of gravity SW1A-SW1C for the container chamber 11 and the distribution material are stored based on the geometry and / or center of gravity information. Thus, the evaluation device 200 can particularly accurately determine and / or determine the current quantity of distribution material or the density and / or volume of the distribution material in the container chamber 11 even with a changing fill level. For this purpose, the position and / or location of the respective container center of gravity SW1A-SW1C is stored in a manner associated with the fill volume, in particular the fill level of the storage container unit 10.

[0042] The evaluation device 200 is further configured to calculate the density of the distribution material based on a mass of the stored and / or filled distribution material, which can be determined by means of the detection means S1-S3, in particular based on a force and / or moment equilibrium. In particular, it is provided that the evaluation device 200 is configured to determine the type and / or grade of the stored and / or filled distribution material based on the determinable density.

[0043] Furthermore, it is provided that a target fill volume can be specified for the distribution machine 100, in particular the evaluation device 200, at the factory and / or temporarily before the distribution material is filled into the storage container unit 10. In particular, it can be provided that the target fill volume can be entered using a mobile operating and / or display means such as a touch display. Using means assigned to the distribution machine 100, the achievement of the target fill volume during filling and / or dispensing of the distribution material can be signaled visually and / or acoustically.

[0044] Fig. 2 shows an exemplary embodiment of a storage container unit 10 according to the invention with an asymmetrically designed container chamber 11, in a schematic representation. In particular, it can be seen that the lower outlet of the container chamber 11 is asymmetrical. As can also be seen, on the basis of the geometry and / or center of gravity information for the container chamber 11, a plurality of container centers of gravity SW1A-SW1C are predetermined, which are located and / or indicated along a center of gravity line 110 assigned to the container chamber 11. The number of predetermined container centers of gravity SW1A-SW1C is only an example. In other exemplary embodiments, more or fewer predetermined container centers of gravity SW1A-SW1C would also be conceivable. The respective current container center of gravity SW1A-SW1C depends on the current fill level orthe currently available quantity of distribution material and / or the volume of the distribution material located in the container chamber 11. This exemplary embodiment also shows that, as the fill level changes, the position and / or location of the container centers of gravity SW1A-SW1C changes not only along or corresponding to the Z-axis and / or a gravitational vector V, but also at least partially along or corresponding to the X-axis (perpendicular to the gravitational vector V). Alternatively or additionally, the container chamber 11 can also be designed such that the position and / or location of the container centers of gravity SW1A-SW1C changes along or corresponding to the Y-axis, as described in more detail below.

[0045] Figures 3A-3C show an exemplary embodiment of a storage container unit 10 according to the invention from different perspectives. As already described in the previous exemplary embodiment, the storage container unit 10, in particular the container chamber 11, is designed by the asymmetry such that the positions and / or locations of the respective container centers of gravity SW1A-SW1C differ in the lateral direction, preferably parallel and / or transverse to the direction of travel F. The storage container unit 10 has a plurality of at least substantially vertical sections AB1, AB2, which are differently inclined and / or aligned with respect to one another. In particular, it can be seen in Figure 3B that the lower and / or first section A1 or the outlet of the container chamber 11 is inclined correspondingly to the direction of travel F and / or along an X-axis.This also results in a center of gravity line 110 of the container chamber 11, which is inclined in sections corresponding to the direction of travel F and / or along the X-axis, whereby the container center of gravity SW1A-SW1C shifts in the direction of travel F and / or along the indicated X-axis or the XZ plane as the fill level increases or decreases.

[0046] As can also be seen from Fig. 3C, the upper and / or second section A2 of the container chamber 11 and thus the center of gravity line 110 of the container chamber 11 is inclined transversely to the direction of travel F and / or along a Y-axis. This results in a center of gravity line 110 of the container chamber 11 which is inclined and / or oriented in different spatial directions in sections and thus also has a kink in the transition area or between the different sections A1, A2. In the upper and / or second section A2 of the container chamber 11, the container center of gravity SW1A-SW1C shifts along the indicated Y-axis or in a YZ plane oriented perpendicular to the XZ plane. As a result, each container center of gravity SW1A-SW1C can be assigned a unique position and / or location or coordinate and can thus be detected particularly well by the evaluation device 200.

[0047] It is understood that the features mentioned in the previously described embodiments are not limited to these specific combinations and are also possible in any other combinations. Furthermore, it is understood that the geometries shown in the figures are only examples and are also possible in any other configurations. List of reference symbols
