Description

[0001] The invention relates to a transfer device for a distribution machine according to the preamble of claim 1 and a distribution machine according to the preamble of claim 13.

[0002] In numerous applications, particularly in agriculture, spreading machines, especially agricultural spreaders, are used to distribute granular material, particularly seeds and / or fertilizer, across a surface. These spreading machines, especially centrifugal spreaders, are preferably designed to be towed by a vehicle and / or mounted on one. The granular material is fed from at least one storage container via at least one adjustable metering device to at least one spreading element, particularly a spreading disc, and / or applied by the spreading element to the surface, particularly the agricultural area.

[0003] Typically, such distribution machines have a transfer device which is preferably arranged between the metering device and the spreading element and is designed to transfer granular material from the metering device to the spreading element, preferably almost independently of external influences.

[0004] Such a distribution machine is described in US 3,085,807 A or WO 2020 / 102878 A1. The distribution machine, particularly an agricultural distribution machine, comprises, in addition to at least one storage container, at least one adjustable metering device, in particular a conveyor belt, by means of which the granular material, in particular seed and / or fertilizer, can be fed to at least one spreading disc. The at least one spreading disc is designed to be driven rotationally about a substantially vertical axis of rotation, wherein the at least one transfer device arranged between the metering device and the spreading disc is configured to transfer the granular material from the metering device to the spreading disc. The transfer device is designed, at least partially, as a funnel-shaped chute and comprises, at least in sections, at least one first side wall and at least one second side wall opposite the first side wall.By means of at least one flow opening arranged adjacent to the first and second side walls, the granular material can be applied to the spreading disc at a preferably defined application point.

[0005] A particular disadvantage of this design is the influence of the metering unit's delivery rate on the application accuracy of the granular material onto the spreading disc. Depending on how much granular material is conveyed by the transfer unit, the lateral distribution, and thus the entire spreading pattern, is negatively affected by the delivery rate. Furthermore, due to the rigid design of the transfer unit, the feed point cannot be adjusted at all, or at least only with considerable effort, depending on external influences such as wind, and / or the material properties of the material being applied. This, in turn, negatively impacts the lateral distribution and thus the spreading pattern.

[0006] The object underlying the invention is therefore to design a distribution machine of the type mentioned above in such a way that a virtually constant scattering pattern can be achieved with varying delivery volumes.

[0007] This problem is solved according to the invention by a transfer device having the features of claim 1.

[0008] As a result of this measure, the granular material, preferably in the form of at least one bundled flow, is fed to the flow opening almost exclusively via the at least one first side wall of the transfer device. The material transferred from the metering device to the transfer device, which is located vertically above the flow opening, can be deflected onto the at least one first side wall by means of the projection. The projection is formed on the at least one second side wall and / or is at least partially connectable to it, and is positioned above the flow opening, preferably between the flow opening and the metering device. This arrangement also makes it possible to implement metering devices with a width in which at least a portion of the metering device overlaps the flow opening of the at least one transfer device in the vertical direction.Furthermore, at least one first side wall and / or projection must have a surface that slopes at least partially downwards in the conveying direction of the granular material. Alternatively or additionally, several slopes of varying degrees along the first side wall and / or projection are conceivable. This allows for more customized conveying of the material within the transfer device.

[0009] Furthermore, the use of different, especially hardened, materials and / or coatings within and / or on material-contacting surfaces of the transfer device is conceivable. These can serve, on the one hand, to enable variable material conveying and / or, on the other hand, to protect the transfer device from wear.

[0010] In addition to the at least one transfer device arranged between the metering unit and the spreading disc, the use of at least one further transfer device is preferred. The at least two transfer devices are designed such that the conveyed material can be transferred from a portion of the metering unit to the respective assigned transfer device. Alternatively, it is also conceivable that each transfer device is assigned at least one metering unit. Thus, the material conveyed by the at least one metering unit can be distributed to several application points, preferably several spreading discs. This results in increased application accuracy and therefore a further improved spreading pattern of the spreading machine.

[0011] In a preferred embodiment of the transfer device for the distribution machine according to the invention, the at least one first side wall extends over a greater width of the metering device than the at least one second side wall. The length of the at least one first side wall is at least equal to, and preferably greater than, that of the at least one second side wall. This design allows for an off-center positioning of the flow opening within the transfer device. Thus, the at least one first side wall can be realized with a particularly large length and therefore with a particularly large capacity for the granular material.

[0012] In a further development of the transfer device according to the invention for the distribution machine, at least one baffle element is assigned to the at least one flow opening, wherein the flow opening is divided into several partial openings by means of the baffle element. The at least one baffle element projects at least partially over and / or into the at least one flow opening, wherein the baffle element is preferably aligned at least partially corresponding to the at least one second side wall. In addition, at least one and / or a further parallel element is conceivable, which is arranged substantially transversely to the first baffle element. Thus, the flow opening can be divided into at least a first partial opening, which faces the first side wall, and at least a further partial opening, which is arranged between the first partial opening and the at least one second side wall.The at least one impact element is preferably at least partially connected to the transfer device by force-fit, form-fit, and / or material-fit connection. Alternatively and / or additionally, at least one impact element integrally formed on the transfer device is conceivable.

[0013] In another preferred embodiment of the transfer device according to the invention for the distribution machine, the granular material can be conveyed through at least one of the several partial openings at a first conveying quantity and through at least one further partial opening at a second conveying quantity that is greater than the first. The first and / or second conveying quantities are to be understood here as specific limit values ​​for a conveyed quantity of granular material, whereby the conveying within the transfer device can be influenced by means of the impact element after the conveying quantity falls below or exceeds at least one limit value. Furthermore, the material can thus be conveyed through the flow opening in at least one concentrated conveying stream until a first and / or second conveying quantity or a first and / or second limit value is reached.Furthermore, at least one impact element is preferred that extends vertically downwards, at least partially, in particular corresponding to the second side wall. This design creates an impact surface for the granular material conveyed transversely to the impact element. The granular material thus impacting the impact element can be deflected, at least partially, in an almost exclusively vertical conveying direction, particularly towards the spreading disc, thereby achieving a further improved bundling of the conveyed flow.

[0014] In another embodiment of the transfer device according to the invention for the distribution machine, the at least one first side wall has at least one substantially upright projecting edge extending in the longitudinal direction, wherein the at least one first side wall is divided by means of the edge into at least one first sliding surface and at least one second sliding surface. The at least one second sliding surface can be arranged vertically at the same height as the first sliding surface and / or preferably above and / or below the first sliding surface. Depending on the quantity conveyed, the granular material can thereby be introduced, at least partially, into the at least one flow opening via one of the several sliding surfaces.The at least one vertically projecting edge is preferably designed such that the at least one first sliding surface is at least partially connected to the at least one second sliding surface by means of the edge. The height of the edge can vary at least in sections or, preferably, be almost uniform throughout.

[0015] Furthermore, at least one second sliding surface that widens at least partially and at least one first sliding surface that narrows at least partially is preferred in the direction of the flow opening.

[0016] In a further preferred embodiment of the distribution machine according to the invention, the at least one first sliding surface is arranged on a side facing the metering device. The respective sliding surfaces are configured to correspond to each other along the at least one first side wall. This arrangement allows for a particularly high throughput of granular material within the transfer device.

[0017] In a further embodiment of the inventive transfer device for the distribution machine, the granular material can be conveyed over the at least one first sliding surface during a first and / or second conveying quantity, and at least partially over the at least one second sliding surface during a third conveying quantity that is greater than or equal to the second conveying quantity. The height of the at least one vertically projecting edge is designed such that a portion of the granular material can only be conveyed over the edge and thus onto the at least one second sliding surface after a limit value of a conveyed quantity or a third conveying quantity has been exceeded. The third conveying quantity can therefore be adjusted, preferably variably, via the height of the edge.

[0018] Furthermore, the transfer device according to the invention comprises at least one rotatable funnel tip, preferably adjoining the flow opening, wherein the feed point is preferably adjustable concentrically to the axis of rotation of the spreading disc by means of the funnel tip. The funnel tip is arranged between the flow opening and the at least one spreading disc, wherein at least one end of the funnel tip, located in the lower region, is at least partially spaced from the spreading disc. The distance of the lower region of the funnel tip to the spreading disc is preferably selected such that throwing vanes, which are designed to protrude substantially upright on the spreading disc, come into almost no contact with the funnel tip.Alternatively and / or additionally, elements, in particular scraper elements, are conceivable that are at least partially integrally formed and / or connectable to the lower region of the hopper tip, by means of which granular material and / or impurities deposited on the throwing vanes can be at least partially scraped off. In this embodiment, the hopper tip is rotatable manually, preferably by hand, and / or automatically, preferably by means of an actuator. An automated design has the advantage of adjusting the feed point during operation of the distribution machine. Thus, a correction of the feed point and therefore of the trajectory characteristics, preferably at least nearly simultaneous, is possible depending on different material properties of the granular material and / or external environmental influences.

[0019] In another preferred embodiment of the transfer device for the distribution machine according to the invention, the funnel tip can be detachably coupled to the funnel-shaped chute, preferably by positive locking and / or without tools. This makes the funnel tip particularly easy to replace if necessary, for example, due to different materials of the granular material and / or for repairs due to wear. Furthermore, a tool-free connection of the funnel tip within the transfer device allows for particularly quick assembly and / or disassembly of the funnel tip. This design is particularly advantageous, for example, when cleaning the funnel tip.

[0020] In a particularly preferred embodiment of the transfer device for the distribution machine according to the invention, the funnel tip is adjustable, preferably lockable, between at least two different positions around the axis of rotation. Preferably, several defined positions are available between which the funnel tip can be rotated and is preferably lockable in at least one of these positions and / or between them. In an automated embodiment, the funnel tip can, for example, be held in a position by means of the actuator, the position preferably being detectable by sensors on the actuator and / or on the funnel tip. For a manually rotatable funnel tip, the fixing can be force-fit and / or form-fit, preferably by means of a screw connection and / or an insertable bolt pin.

[0021] Furthermore, the axis of rotation of the funnel tip can at least partially coincide with the axis of rotation of the scattering disc or alternatively be designed to correspond to it.

[0022] In a particularly preferred embodiment of the transfer device according to the invention for the distribution machine, the transfer device, in particular the hopper tip, comprises at least one display means, wherein the position of the hopper tip about the axis of rotation can be read by means of the display means. The display means is associated with the transfer device and is arranged such that it is visually perceptible to an operator inside a towing vehicle and / or in the area of ​​the transfer device. The display means is configured to show the position of the hopper tip in an analog and / or digital display, wherein, in the case of a digital display, the position can alternatively and / or additionally be displayed by a display present on the distribution machine and / or the towing vehicle.

[0023] Furthermore, a display device is particularly preferred which has a label readable by an operator and at least one additional cam corresponding to the label. A bolt- and / or pin-shaped element can be inserted at least partially through the at least one cam, with at least one fixing element on the underside of the display device being attachable to the bolt- and / or pin-shaped element. A pin-shaped element designed as a screw and a fixing element designed as a wing nut, which can be screwed onto the screw, are particularly preferred. The display device and / or the funnel tip can thus be fixed particularly easily and / or securely in a position adjustable by the operator.

[0024] In a further particularly preferred embodiment of the transfer device according to the invention for the distribution machine, the funnel tip has at least one discharge opening through which the conveyed material can be transferred to the feed point on the spreading disc, wherein the granular material can be conveyed to the discharge opening via at least one inner surface of the funnel tip. The at least one inner surface is inclined relative to a horizontal plane such that the granular material can be conveyed towards the discharge opening and thus to the feed point on the spreading disc, preferably without any additional action. The at least one discharge opening is preferably arranged such that the discharge opening of the funnel tip and the flow opening between the funnel-shaped chute and the funnel tip do not overlap in the vertical direction.This ensures that material that can be introduced into the funnel tip can be conveyed to the spreading disc almost exclusively via at least one inner surface of the funnel tip.

[0025] In a further particularly preferred embodiment of the transfer device according to the invention for the distribution machine, the at least one inner surface of the funnel tip has at least one guide element, wherein the conveyed material can be divided, preferably up to a fourth conveying quantity, at least partially into several conveying streams by means of the guide element. The fourth conveying quantity can correspond at least approximately to one of the aforementioned first to third conveying quantities or may deviate from them. The at least one guide element is connectable to and / or integrally formed with the inner surface of the funnel tip, wherein the guide element is arranged substantially upright, preferably projecting from the inner surface. Preferably, a guide element is required that has a width and / or height that increases at least section by section in the direction of a central and / or rotational axis of the discharge opening.This allows for a particularly gentle deflection of the conveyed flow or the conveyed granular material within the transfer device. The guide element enables at least a partial enlargement, and especially a widening, of the feed point, particularly at low conveying volumes. This allows for at least partial compensation of feed point size, especially width, which varies depending on the conveying volume, thus further increasing application accuracy.

[0026] In a further advantageous embodiment of the inventive transfer device for the distribution machine, the funnel tip has at least one rebound element in the area of ​​and / or adjacent to the dispensing opening. The rebound element is formed in one piece or in multiple parts and is at least partially connected to and / or integrally formed with the funnel tip. The rebound element is designed to at least partially return material striking the spreading disc and rebounding towards the transfer device back to the spreading disc, so that granular material can be applied to the area, particularly in agricultural areas, almost exclusively via the at least one spreading disc.

[0027] In a further advantageous embodiment of the inventive transfer device for the distribution machine, the rebound element extends at least partially from an outer contour of the discharge opening towards the outer radius of the spreading disc. The outer contour of the rebound element is preferably circular, at least in sections, and in particular substantially corresponding to the spreading disc. The rebound element is configured to at least partially shield the at least one spreading disc in the vertical direction. This ensures that the granular material introduced onto the spreading disc can be retained at least partially, preferably with virtually no loss, on the spreading disc, thus enabling a particularly high conveying speed and / or conveying volume of the granular material.

[0028] Further details of the invention can be found in the description of the example and the drawings. The drawings show Fig. 1. An agricultural spreading machine towed by a tractor in a perspective view; Fig. 2 a transfer device according to the invention at the in Fig. 1 agricultural distribution machine shown in a perspective view; Fig. 3 the transfer device from Fig. 2 in a top view; Fig. 4 the transfer device from Fig. 3 in a sectional view from the rear; Fig. 5 the transfer device from Fig. 4 in a sectional view from the side; and Fig. 6 the transfer device from Fig. 4 in a perspective sectional view with a diffuser.

[0029] An agricultural spreading machine 20, which is coupled to a towing vehicle 10 via a drawbar 22, is in the Fig. Figure 1 shows the distribution machine 20, designed as a centrifugal spreader, which includes a storage container 21 for granular material 23, in particular seed and / or fertilizer. A metering device, designed as a conveyor belt 24, is arranged in the lower part of the storage container 21. This device conveys adjustable quantities of granular material 23 from the storage container 21 against the direction of travel F to a transfer device 30. The material 23, which can be fed from the metering device 24 into the transfer device 30, is then fed by the transfer device 30 to two spreading discs 50 arranged vertically below it. Each of these discs is rotatably driven about a substantially vertical axis of rotation R. The spreading discs 50 are designed to distribute the granular material 23 fed onto them in the form of at least one spreading pattern over an area, particularly an agricultural area.

[0030] The transfer device 30, arranged between the metering device 24 and the scattering discs 50 and designed at least partially as two mirror-symmetrical funnel-shaped chutes, is in the Fig. 2 shown. Each of the funnel-shaped chutes comprises at least a first side wall 31 and a second side wall 32 opposite the first side wall 31. The granular material 23 is thereby almost exclusively conveyed via the first side wall 31 into a chute in which Fig. 3 and Fig. Flow opening 34, shown in the 4, is arranged adjacent to the first and second side walls 31, 32. As shown in the Fig. 3 and Fig. As can also be seen in Figure 4, the second side wall 32 has a projection 33 extending towards the first side wall 31, which, together with the metering device 24, extends at least partially over the flow opening 34. By means of the projection 33, the material 23, which can be introduced vertically above the flow opening 34 from the metering device 24 into the transfer device 30, can be diverted onto the first side wall 31, which extends over a greater width of the metering device 24 than the second side wall 32. Thus, a transfer device 30 is achieved that allows for a particularly wide inlet area and therefore a particularly wide metering device 24, especially with a large conveying volume of granular material 23.

[0031] Furthermore, the transfer device 30 includes an impact element 35, which is associated with the flow opening 34 and by means of which the flow opening 34 is divided into several, in particular two, partial openings. The impact element 35 is arranged within the transfer device 30 such that the granular material 23 can be conveyed through only one of the partial openings of the flow opening 34 for a first conveying quantity and through two of the several partial openings for a second conveying quantity that is larger than the first conveying quantity. The impact element 35 also extends downwards in a vertical direction over a certain section and thus deflects the material 23 that can be introduced into the partial openings at least partially into an almost exclusively vertical conveying direction.

[0032] Furthermore, the first side wall 31 has a longitudinally extending, vertically projecting edge 36, by means of which the first side wall 31 is divided into a first and second sliding surface 37, 38, and over which the granular material 23 can be conveyed depending on the conveying quantity. The first sliding surface 37 is located on a side facing the metering device 24. The height of the edge 36 is designed such that the edge 36 only protrudes at least partially in the direction of the arrow, as shown in the figure, after the fourth conveying quantity has been reached. Fig. Figure 5 shows that the conveyed material 23 can be exceeded. Thus, the granular material 23 can be conveyed at least partially via the first sliding surface 37 for a first and / or second conveying quantity, and at least partially via the second sliding surface 38 for a third conveying quantity that is greater than or equal to the second conveying quantity, to the flow opening 34.

[0033] Furthermore, the transfer device 30 comprises a rotatable funnel tip 40 arranged adjoining the flow opening 34, in particular between the funnel-shaped chute and the spreading disc 50. The granular material 23, which can be introduced into the funnel tip 40 via the flow opening 34, can be conveyed via at least one internal surface in the funnel tip 40 to an adjoining discharge opening 42. From the discharge opening 42, the granular material 23 can be transferred by means of the funnel tip 40 to at least one feed point A on the spreading disc 50. The feed point A is adjustable via the funnel tip 40, in particular concentrically to the axis of rotation R of the spreading disc 50. Alternatively, the funnel tip 40 is designed such that the feed point A is adjustable, alternatively and / or additionally, in a direction transverse to the axis of rotation R.

[0034] According to the invention, the funnel tip 40 is detachably, and in particular positively, connected to the funnel-shaped chute below and / or in the region of the flow opening 34. The positive connection is designed such that the funnel tip 40 is adjustable within a specific range between at least two positions, in particular lockable about the axis of rotation R. The position adjustable by means of the funnel tip 40, in particular an angle adjustable about the axis of rotation R, can be read via a display means 41 associated with the transfer device 30. In the illustrated embodiment, the display means 41 is integrally formed on the upper region of the funnel tip 40 and is made of the same material as the funnel tip 40. Alternatively and / or additionally, the display means 41 can also be at least partially connected to the funnel tip 40.In the illustrated embodiment, the display means 41 comprises a pointer element 45 and a label applied to the display means 41. Depending on the position of the pointer element 45 above the label, the adjustable position can be read by an operator.

[0035] Alternatively and / or additionally, a digital display device 41 is conceivable for an automated adjustment of the funnel tip 40, in particular by means of an actuator. The display device 41 can be located in the area of ​​the transfer device 30 and / or in the towing vehicle 10.

[0036] To fix the position, the pointer element 45 has a screw projecting through the indicator means 41, in particular through a cam 46 formed on the indicator means 41, by means of which the funnel tip 40, in particular the indicator means 41, can be fixed via a wing nut that can be screwed onto the screw.

[0037] The Fig.Figure 6 shows a detailed representation of the conveying path of the granular material 23 from the transfer device 30 to the spreading disc 50. Up to a certain conveying quantity, the granular material 23 can be at least partially divided into several conveying streams by means of a guide element 43 molded onto the inner surface of the funnel tip 40. Alternatively and / or additionally, a guide element 43 that is at least partially connected to the funnel element 41, in particular by a form-fit, force-fit, and / or material-fit connection, is conceivable. The guide element 43 is formed, particularly in its lower region, on the inner surface of the funnel tip 40, with the width of the guide element 43 increasing from an origin towards the discharge opening.Thus, the guide element 43 is designed to redirect the material 23 that can be applied at the feed point A in such a way that the size difference, in particular the width difference, of the feed point A can be at least partially compensated for at small and large feed rates. This ensures a nearly constant application accuracy of the granular material 23 onto the spreading disc 50, even with fluctuating feed rates, and therefore an improved spreading result of the distribution machine 20.

[0038] Furthermore, the funnel tip 40 comprises at least one rebound element 44 arranged in the lower region, particularly adjacent to the discharge opening 42. The rebound element 44 is specifically designed to retain material 23 rebounded from the diffuser 50, particularly in a vertical upward direction, at least partially within the region of the diffuser 50 and / or to return the material 23 to the diffuser 50. The rebound element 44 extends at least partially from the outer contour of the discharge opening 42 towards the outer radius of the diffuser 50. In the illustrated embodiment, the rebound element 44 is integrally formed on the funnel tip 40, with the rebound element 44 and the funnel tip 40 being made of the same material.In an alternative embodiment not shown, the rebound element 44 can be at least partially connected to the funnel tip 40 by force and / or form and / or material connection.
