DEVICE FOR DISTRIBUTING LIQUID

Description

[0001] The invention relates to a device for spreading liquid manure according to the preamble of claim 1.

[0002] Slurry for fertilizing soils, fields, and fields is typically spread using appropriate slurry spreading vehicles. These are typically equipped with a device that includes at least one distributor, a distribution pipe, or a distribution plate. With devices that feature a distribution pipe, the slurry is pumped from an external slurry storage tank to the distribution pipe, from where it is spread at the desired location. During spreading, the distribution pipe is essentially positioned transversely to the direction of travel of the spreading vehicle, at least for the duration of the application, in order to distribute the slurry over the largest possible area. During this "active position," the mobility of the slurry spreading vehicle is severely restricted.

[0003] Due to the fact that manure often contains coarse and solid components, the outlet openings of the distribution pipe can become clogged, preventing even distribution of the manure. Furthermore, it is desirable to control the flow of manure into the field to prevent over-fertilization.

[0004] A further disadvantage resulting from the current devices is that the distribution pipes only release the slurry over spatially limited areas - usually outlet holes - which means that behind the spreading vehicle both "strip-like" slurry traces and traces containing little or no slurry can form.

[0005] DE 197 03 183 C2 describes a manure distributor. This distributor can be connected to a manure storage tank and comprises a plurality of hoses that transport the manure from an outlet to just above the soil to be fertilized. Each of the hoses is connected to the distributor's outlet via a separate outlet opening.

[0006] GB 1 576 775 A describes a device for distributing liquid manure. The outlet opening for the liquid manure in this device is formed by a horizontally oriented slot, the width of which is adjustable.

[0007] The invention is therefore based on the object of eliminating the disadvantages of the prior art and providing a device for spreading liquid manure that can be used to optimize the application of liquid manure. The device is intended, in particular, to ensure uniform distribution of liquid manure across the field, simple control of the application of liquid manure, and a high degree of mobility for the spreading vehicle. The main features of the invention are defined in the characterizing part of claim 1. Specific and advantageous embodiments are the subject of the dependent claims.

[0008] To achieve this objective, the invention provides a device for distributing liquid manure, comprising at least one distribution unit and a holder for attaching the at least one distribution unit to a liquid manure storage tank. The at least one distribution unit comprises a distributor and a hose system. The device is characterized by at least one distribution pipe, the distribution pipe having inlet openings along a lateral surface for fluid-tight connection of the distribution pipe to the hose system.

[0009] The device is further characterized in that the distributor pipe has at least one outlet opening along its outer surface, which extends essentially in a longitudinal direction of the distributor pipe. The manure storage unit is not a component of the device according to the invention.

[0010] The inventive design of the distribution pipe has the advantage of ensuring an even distribution of the manure across the field, as the manure can be distributed across the soil along the entire length of the slot-shaped outlet opening. For this purpose, the outlet opening is arranged in the outer surface of the distribution pipe on a side of the distribution pipe facing the soil. This prevents the formation of unwanted manure traces.

[0011] The proposed method allows the manure to be spread very close to the ground. The manure is distributed directly from the distribution pipe onto the ground. This close-to-ground distribution has the advantage of significantly reducing odor nuisance, as the manure no longer splashes and partially enters the ambient air as aerosols, yet the manure is still spread over a large area.

[0012] In a preferred embodiment of the proposal, the distribution pipe has a longitudinal, slot-shaped outlet opening. The at least one outlet opening is dimensioned such that the liquid manure does not immediately flow out of the distribution pipe, but rather spreads slightly, and, on the other hand, is not chosen so small that this outlet opening becomes clogged and blocked during operation. It has been found that a slot-shaped outlet opening is advantageous for this purpose, with the slot preferably being located in the longitudinal direction of the distribution pipe.

[0013] For the purposes of this application, "slot-shaped" is understood to mean a preferably rectangular shape whose long sides are at least twice, preferably at least five times, as long as their short sides. It is also possible for the short sides to be rounded.

[0014] Furthermore, the invention does not specify the design of the outlet opening. It is highly variable. For example, the outlet opening can be circular, oval, triangular, polygonal, or even square. The inventive solution encompasses proposals in which only one, possibly long and large, outlet opening is provided, as well as solutions in which a plurality of identical or different outlet openings are used.

[0015] Therefore, according to an advantageous further development, a plurality of outlet openings are provided on the distributor pipe. Such a design has advantages for the stability of the distributor pipe.

[0016] In a preferred embodiment of the proposal, the outlet openings are arranged one behind the other and / or offset from one another in the longitudinal direction of the distribution pipe. Such a proposal combines appropriate stability of the distribution pipe with high variability in the use of the invention. For example, it is provided that the distribution pipe is adjustable about its longitudinal axis, thus providing different outlet openings near the ground, depending on the position of the distribution pipe. This allows both the distribution pattern of the slurry on the ground and the amount of slurry distributed to be adjusted.

[0017] In an advantageous embodiment, a closure device is provided which can be positioned in various positions and which more or less exposes the outlet opening(s) in these different positions. The proposed closure device consists of a plurality of covers, with each outlet opening ideally being assigned a cover. The cover is movably mounted on a guide. The guide is aligned, for example, parallel to the longitudinal direction of the distribution pipe, but a guide in the circumferential direction can also be provided. The covers are movable together by means of a common, central rod. Such a configuration makes it possible to realize, in particular, a continuous adjustment of the application rate of liquid manure.

[0018] According to a further embodiment, the at least one, preferably slot-shaped outlet opening has a length that is at least a quarter, preferably at least half, of the length of the distribution pipe. According to a particularly preferred embodiment, the slot-shaped outlet opening extends substantially over the entire length of the distribution pipe. This ensures that the liquid manure is spread evenly below the distribution pipe, instead of being limited to specific areas below the distribution pipe. In the latter case, both "strip-like" liquid manure traces and traces that contain no liquid manure at all can form behind the spreading vehicle. The outlet opening according to the invention prevents such trace formation. The at least one outlet opening preferably runs parallel along the longitudinal direction of the distribution pipe.However, it is also conceivable that the outlet opening runs at a slight angle to the longitudinal direction, i.e. spirally, along the outer surface of the distributor pipe.

[0019] According to an advantageous embodiment, the device comprises a supply hose that connects the at least one distributor to the manure storage in a fluid-tight manner. The manure can be pumped from the manure storage to the distributor via the supply hose. The hose is preferably flexible to withstand the folding and unfolding movements of the device. PVC or rubber hoses, for example, are conceivable.

[0020] In a preferred embodiment, the distributor pipe is made of iron or steel. It is also possible to manufacture the distributor pipe from aluminum, for example, an extruded aluminum profile. Aluminum, or other light metals or light metal alloys, have the advantage of being lighter while maintaining the same high mechanical strength, thus increasing the payload. However, it is also possible to manufacture the distributor pipe from plastic (e.g., PE or PVC), which offers advantages during production and further reduces weight. Plastics are also known that can be used permanently, even under abrasive stress.

[0021] It is furthermore possible for the hose system to comprise a plurality of hoses, each of which connects the distributor to one of the inlet openings in a fluid-tight manner. The manure is pumped through the hose system from the distributor to the distribution pipe. Like the supply hose, the hoses of the hose system can also be made of PVC or rubber in order to allow movement in different directions. According to a further development of the device, it is also provided that the inlet openings are designed as preferably flexible filling nozzles that are distributed essentially evenly over the length of the distribution pipe. Such a design of the hose system and inlet openings has the advantage that the manure arrives at different points on the distribution pipe at the same time, which leads to better distribution of the manure within the pipe.In addition, such a design ensures a higher load-bearing capacity of the device due to the flexible elements, which leads to low maintenance costs and an increased service life.

[0022] In an advantageous variant, the distribution pipe has a conveyor screw arranged in an interior of the distribution pipe. The conveyor screw is particularly suitable for distributing liquid manure and has a drive shaft via which it can be driven. The conveyor screw also serves to press the liquid manure out of the slot-shaped outlet opening. Furthermore, the conveyor screw can have cutting elements that serve to shred the liquid manure. The drive shaft for driving the conveyor screw is preferably arranged outside the distribution pipe, wherein the drive shaft can have a housing that is flush with the distribution pipe. With a conveyor screw, the liquid manure can be easily spread onto the field from the at least one outlet opening.

[0023] However, the proposed solution is also functional without the use of a screw conveyor. It should be noted that the slurry is pumped from the slurry storage tank into the distribution pipe using hydraulic pumps, i.e., under appropriate pressure. If these hydraulic pumps are appropriately dimensioned, they force the slurry through the slotted outlet opening, thus distributing the slurry according to the invention.

[0024] According to a further embodiment, the holder comprises a frame. The frame preferably has a wing on each of two opposite side parts, wherein each wing is pivotally connected to the frame via a joint or hinge connection. According to an advantageous embodiment, it is also provided that a distribution unit is arranged on each wing. It can further be provided that the frame and / or the wings each have at least one wheel or sliding plate. The wheels or sliding plates of the holder, i.e. of the frame and / or the wings, serve to bear at least part of the weight of the device in the active position and thus prevent the towing vehicle from lifting and the associated loss of ground traction and ultimately of the driving force.The "active position" refers to the position of the device in which it is positioned for the duration of the slurry spreading on the field. In this position, the at least one distribution pipe is essentially aligned transversely to the direction of travel of the spreading vehicle. Furthermore, in the active position, the at least one distribution pipe is held only slightly above the ground. The distance between the ground and the distribution pipe is preferably approximately 5 to 30 cm. In contrast, the "inactive position" refers to the position of the device in which the at least one distribution pipe is not positioned transversely to the direction of travel of the spreading vehicle, but instead in the direction of travel next to the slurry storage tank. For this purpose, the frame is folded up in the inactive position, i.e., perpendicular to the ground. Accordingly, in the active position of the device, the frame is unfolded, i.e.,essentially parallel to the ground.

[0025] The frame is advantageously connected either to the spreading vehicle or to the slurry storage unit via a joint or hinge connection. The joint or hinge connection allows the bracket (and thus the at least one distribution system) to be moved from the inactive position to the active position or from the active position to the inactive position.

[0026] According to one possible embodiment, the wheels of the frame and / or the wings are rotatably mounted on the frame or wings, respectively, whereby each wheel forms a rotation axis that runs perpendicular to the wheel's rotation axis. This significantly minimizes the risk of wheel dragging or locking when the spreading vehicle corners. This increases the mobility and maneuverability of the device, facilitating the spreading of slurry in the field. Skid plates can also be used to support the frame and / or wings.

[0027] The device preferably comprises two distribution units, one unit being arranged on each of the two wings. The device can be designed such that, in the active position of the device, the distribution pipes of the two distribution units are held in a line next to one another such that they form an optical unit. This optical unit, consisting of the two distribution pipes arranged in an extension, has a total length that corresponds at least to the axle width of the application vehicle. Preferably, the two distribution pipes held next to one another are together at least twice as long as the axle width of the application vehicle.It can also be provided that the supply hose has a T-piece connection or a Y-piece connection which connects a main section of the supply hose to two side sections of the supply hose, wherein each of the side sections of the supply hose is assigned to a distributor of the two distribution units.

[0028] The design of the device with two separate distribution units also has the advantage that, in the inactive position, the respective distribution pipes can be arranged parallel to the direction of travel on two opposite sides of the spreading vehicle or slurry storage tank. This type of design for a slurry spreading device allows for particularly space-saving transport and storage when not in use.

[0029] It is also conceivable for the device to have at least one double-acting cylinder for folding the frame up and down and / or for pivoting the leaves in and out. This allows the device to be moved effortlessly from the active position to the inactive position or from the inactive position to the active position.

[0030] Furthermore, the device can be provided with at least one hydraulic motor for driving the conveyor screw. A hydraulic motor has the advantage over an internal combustion or electric motor that it can be connected to the same hydraulic system, for example, together with the double-acting cylinders. This significantly minimizes maintenance effort because only one system (the hydraulic system) needs to be maintained.

[0031] A further embodiment may be based on the device having at least one first hydraulic pump for pumping the manure from the manure storage to the at least one distributor. Accordingly, it is also possible for the device to have at least one second hydraulic pump for pumping the manure from the distributor to the distribution pipe.

[0032] Advantageously, it is further provided that the distributor is in particular hydraulically driven and in particular also has a hydraulic pump for pumping the liquid manure from the distributor to the distribution pipe.

[0033] Hydraulic pumps can also be connected to the hydraulic system, which also uses the cylinders and hydraulic motor, which also minimizes maintenance requirements.

[0034] Alternatively, the slurry is transported from the slurry storage facility to the distributor by gravity or with the aid of a vacuum pump, or is sucked or pumped by the pumping action of the slurry storage facility.

[0035] According to a further embodiment, the device comprises at least one control unit. The control unit can be designed, in particular, to enable control of the at least one double-acting cylinder, the at least one hydraulic motor, the first hydraulic pump, and / or the second hydraulic pump.

[0036] Further features, details, and advantages of the invention will become apparent from the wording of the claims and from the following description of exemplary embodiments with reference to the drawings. They show: Fig. 1 is a perspective view of a device for spreading liquid manure in an inactive position according to the invention; Fig. 2 is a perspective view of a device for spreading liquid manure in an active position according to the invention; Fig. 3 is a schematic view of a distribution unit according to the invention; Fig. 4 is a schematic view of a cross section of a distribution pipe according to the invention; Fig. 5 is a schematic representation of a hydraulic system of the device according to the invention. Figs. 6-8 are each a view of different variants of the distribution pipe according to the invention; Fig. 9a, 9b are each a view of different positions of the closure device of the distribution pipe according to the invention.

[0037] In the following, similar or identical features are identified by the same reference symbols.

[0038] Figure 1shows a perspective view of a device 1 for spreading liquid manure in an inactive position. Figure 1 The device 1 shown comprises two distribution units 2 and a holder 3 for fastening the two distribution units 2 to a liquid manure storage 4, wherein the liquid manure storage 4 itself is not part of the device 1 according to the invention.

[0039] Each distribution unit 2 comprises a distributor 5, a hose system 6 consisting of a plurality of hoses 15 and a distributor pipe 7. The distributor pipes 7 each have inlet openings 9 along their outer surface 8 for fluid-tight connection of the distributor pipe 7 with the hoses 15 of the hose system 6. In addition, the distributor pipes 7 of the Figure 1The device 1 shown has a slot-shaped outlet opening 10 with a length 12 along its outer surface 8, which extends in the longitudinal direction of the distributor pipe 7. Due to the perspective view, in Figure 1 only one of the two longitudinal slot-like outlet openings 10 of the device 1 can be seen. The outlet opening 10 extends almost over the entire length 13 of the distributor pipe 7 (see Figure 3 ) .

[0040] The holder 3 comprises a frame 19 with two opposite side parts 20, on each of which a wing 21 is arranged (only one wing 21 shown). The wings 21 are pivotally connected to the side parts 20 of the frame 19 via a joint or hinge connection 32. The distribution units 2 are arranged on the pivotable wings 21.

[0041] The Figure 1The device 1 shown is in an inactive position. In this position, the device 1 can be easily transported or stored. The frame 19 is folded up, i.e., it is in a position perpendicular to the ground. The wings 21 and thus the distribution pipes 7 are also folded in such a way that they are positioned laterally next to the slurry storage 4 and thus parallel to the direction of travel of the spreading vehicle.

[0042] Figure 2shows a perspective view of a device 1 for spreading liquid manure in the active position, i.e. in the position in which the liquid manure can be released onto the field. The device shown comprises two distribution pipes 7, which are aligned essentially transversely to the direction of travel of the spreading vehicle. The distribution pipes 7 are also located close to the ground (preferably 5 cm or 10 cm to 20 cm or 30 cm from the ground). For this purpose, the frame 19 is fully unfolded so that it is essentially in a position parallel to the ground. In addition, both wings 21 are unfolded so that they are also parallel to the ground and in a position transverse to the direction of travel. In the active position, both distribution pipes 7 are arranged next to one another in a common line.In order to support part of the weight of the distribution units 2 and the holder 3, the wings 21 each have a wheel 22a, 22b at their outer ends, which is connected to the wing 21 so as to be rotatable about a vertically oriented axis of rotation 33. The axis of rotation 33 runs perpendicular to the axis of rotation of the wheel 22. This reduces the risk of the wheels 22 dragging or locking when the application vehicle corners. Additional wheels 22c, 22d, for example at the other ends of the wings 21 or on the frame 19, can also be provided, but are not shown in the drawing. Figure 2 not shown. It is intended that the wheels 22c, 22d are located in the middle area of ​​the device, at the level of the rear of the slurry storage 4, and here allow an additional assessment of the load on the ground (see Fig.1 ).

[0043] As from Figure 2As can be seen further, the device 1 has a supply hose 14. The distributors 5 are connected to the slurry storage 4 in a fluid-tight manner via the supply hose 14. For this purpose, the supply hose 14 has a T-piece connection 25 which divides the supply hose 14 into a main section 26 and two side sections 27, wherein each of the side sections 27 of the supply hose 14 is assigned to a distributor 5 of the two distribution units 2. The T-connection 25 allows two distributors 5 to be supplied simultaneously from one slurry storage 4.

[0044] Figure 3shows a schematic view of a distribution unit 2, wherein the device 1 is in its active position. A distributor 5 is shown, which is fluid-tightly connected to a slurry storage 4 via a supply hose 14. The supply hose 14 can be divided into a main section 26 and a side section 27, which are each connected to each other via a T-piece connection 25. Via the distributor 5, the slurry is pumped from the slurry storage 5 via a hose system 6 comprising a plurality of hoses 15 to the inlet openings 9 of the distributor pipe 7. As shown in Figure 3 As shown, the inlet openings 9 are distributed substantially over the entire length 13 of the distributor pipe 7, whereby a uniform filling of the pipe 7 can be ensured.

[0045] The distributor pipe 7 also has a longitudinal, slot-shaped outlet opening 10, which is arranged on a side of the distributor pipe 7 facing the ground in the jacket surface 8 of the distributor pipe 7. According to the Figure 3 In the embodiment shown, the slot-shaped outlet opening 10 extends substantially over the entire length 13 of the distribution pipe 7. This ensures that the liquid manure is distributed evenly beneath the distribution pipe, rather than being limited to specific areas beneath the distribution pipe. The length of the outlet opening 10 is indicated by 12.

[0046] The illustrated distribution unit 2 is carried by a bracket 3 comprising a frame 19 and two wings 21 pivotally connected to the frame 19, only one wing 21 being shown. At least the distributor 5 and the distribution pipe 7 are attached to the wing 21. The wing 21 has a wheel 22a at its end, which, in the active position, points outwardly away from the slurry storage 4. As shown in Figure 3 As shown, the frame 19 of the bracket 3 has a further wheel 22c in the center. The wheels 22a,c of the bracket 3 serve primarily to support at least part of the weight of the bracket 3 and the distribution unit 2 in the active position, thus preventing the towing vehicle from lifting and thus resulting in a loss of ground traction and ultimately the driving force of the towing vehicle.

[0047] In a preferred variant, the wheels 22a to 22d are adjustable in position and height relative to the wings 21, ultimately resulting in an adjustable height of the outlet opening 10 relative to the floor. Such adjustability can also be achieved automatically, for example, by means of appropriate (hydraulic) actuators or the like.

[0048] In Figure 4 A schematic view of a cross-section of a distribution pipe 7 is shown. The liquid manure is pumped via the hoses 15 of the hose system 6 and through the filling nozzle 16 into the interior 18 of the distribution pipe 7. There, a conveyor screw 17 with a drive shaft 23 ensures even distribution of the liquid manure within the distribution pipe 7.

[0049] The outlet opening 10 is located in the lower area, ideally directly above the ground in its immediate vicinity. A particular advantage of the proposed invention is that the outlet opening 10 is positioned very close to the ground, thus preventing or reducing aerosol formation and distributing the liquid manure as evenly as possible over the ground.

[0050] Furthermore, the conveyor screw 17 pushes the liquid manure out of the slot-shaped outlet opening 10 through a continuous rotary motion. Furthermore, the conveyor screw 17 can have cutting elements that serve to shred the liquid manure. The drive shaft 23 for driving the conveyor screw 17 is driven by a hydraulic motor and is preferably arranged outside the distribution pipe 7. The drive shaft 23 can have a housing that is flush with the distribution pipe 7.

[0051] In Figure 5Finally, a schematic representation of a hydraulic system 35 of the device 1 is shown. The hydraulic system 35 initially comprises a hydraulic pump 36, which is driven, for example, via the power take-off shaft 37 from the drive shaft of the tractor. The hydraulic pump 36 preferably draws hydraulic oil from an oil reservoir 38. The oil flows are distributed accordingly in the control unit 24. For this purpose, the hydraulic system 35 further comprises two hydraulic motors 29, each hydraulic motor 29 driving a conveyor screw 17, and a hydraulic pump that pumps slurry from the slurry storage 4 to the distributors 5. The distributors 5 are also hydraulically driven and may also have a hydraulic pump. The distributors 5 also belong to the hydraulic system 35.

[0052] Furthermore, the hydraulic system 35 comprises four double-acting cylinders 28 for folding the frame up and down or for pivoting the wings 21 in and out. The hydraulic system 35 can be controlled by a common control unit 24, which comprises manually and / or automatically operated control valves.

[0053] The Fig. 6-8 show different variants of the distribution pipe 7.

[0054] In Figure 6 A slot-shaped outlet opening 10 extends over the entire longitudinal extent of the distributor pipe 7. For this purpose, the distributor pipe 7 is slotted longitudinally. Advantageously, circumferentially extending tabs 41 are welded to the slot-shaped outlet opening 10, preferably at its end and central region, to stabilize the distributor pipe 7.

[0055] In Figure 7Instead of a single slot-shaped outlet opening 10, a plurality of smaller outlet openings 10a, 10b, 10c, 10d are provided. These are arranged one behind the other in the longitudinal direction of the distributor pipe 7, with a small distance between them. The distance between them is smaller than their longitudinal extent.

[0056] In the Figure 8 In the embodiment shown, two rows of slot-shaped outlet openings 10a, 10b, 10c, 10d are arranged next to each other and offset by a gap. The outlet openings 10a, 10b, 10c, 10d are preferably all the same length. The arrangement is selected such that the length of the respective outlet openings corresponds to their distance from one another, and thus, viewed in the longitudinal direction, manure can be delivered over the entire length of the distribution pipe, which, when used with such a distribution pipe, results in a streak-free application pattern.

[0057] The proposal according to Figures 9a and 9b builds on the distributor pipe 7 Figure 8 Here, too, the distributor pipe 7 has two rows of outlet openings 10. The outlet openings of the upper row are designated by reference numerals 10a, 10b, 10c, 10d, while the outlet openings of the lower row are designated by reference numerals 10aa, 10bb, 10cc, 10dd.

[0058] A common closure device 40 is provided for the outlet openings 10a, 10b, 10c, 10d, 10aa, 10bb, 10cc, 10dd. The closure device 40 consists of three parallel guide rails 44a, 44b, and 44c running in the longitudinal direction of the distributor pipe 7. The middle guide rail 44b is located between the two rows of outlet openings 10. The upper row of outlet openings 10a, 10b, 10c, 10d is located between the middle guide rail 44b and the upper guide rail 44a. The lower row of outlet openings 10aa, 10bb, 10cc, 10dd is located between the middle guide rail 44b and the lower guide rail 44c.

[0059] For each outlet opening 10a, 10b, 10c, 10d, 10aa, 10bb, 10cc, 10dd, a cover 45a, 45b, 45c, 45d, 45aa, 45bb, 45cc, 45dd is provided. The covers 45a, 45b, 45c, 45d, 45aa, 45bb, 45cc, 45dd are movably arranged on the guide rails 44a, 44b, and 44c and are movable together by a central linkage 46. The covers 45a, 45b, 45c, 45d are mounted on the middle and upper guide rails 44b and 44a and the covers 45aa, 45bb, 45cc, 45dd are mounted on the middle and lower guide rails 44b and 44c.

[0060] At the right end, the central rod 46 has a handle 42 by which the closure device 40 is adjusted in the longitudinal direction of the distributor pipe 7 and thus the opening area of ​​the outlet openings 10a, 10b, 10c, 10d, 10aa, 10bb, 10cc, 10dd can be changed and adjusted. This is shown in Figure 9b shown, in which the central rod 46 is moved by the handle 42 to the right (see arrow 43 in Figure 9a ) and thus the covers 45a, 45b, 45c, 45d, 45aa, 45bb, 45cc, 45dd each cover a part of the outlet opening 10a, 10b, 10c, 10d, 10aa, 10bb, 10cc, 10dd. This is indicated by the dashed area of ​​the outlet opening 10a, 10b, 10c, 10d, 10aa, 10bb, 10cc, 10dd, which is covered by the covers 45a, 45b, 45c, 45d, 45aa, 45bb, 45cc, 45dd.
