[0002] Distribution device for a pneumatically operating agricultural distribution machine and method for operating a distribution device

[0003] The invention relates to a distribution device for a pneumatically operating agricultural distribution machine according to the preamble of patent claim 1 and to a method for operating a distribution device of a pneumatically operating agricultural distribution machine according to the preamble of patent claim 18.

[0004] The distribution system of agricultural distribution machines typically has an internal distribution chamber into which the material to be distributed can be introduced via an inlet. The material introduced into the distribution chamber is then discharged from the distribution chamber via several outlets.

[0005] Distribution devices are already known in the prior art, which comprise a distribution manipulator for adjusting the distribution of the material flowing into the distribution chamber via the inlet to the outlets. Such a distribution device is known, for example, from WO 2020 / 033845 A1.

[0006] The distribution manipulator can, for example, have a baffle supported by a movable baffle support, which is arranged opposite the inlet of the distribution chamber, so that material flowing into the distribution chamber hits the baffle and bounces off the baffle. Using an adjustment device, the position of the baffle can then be changed, for example, to adjust the distribution.

[0007] The known distribution manipulators have various disadvantages due to their concept and design. For example, the adaptability of the distribution of the distribution material is limited due to the limited possibilities of the

[0008] REPLACEMENT SHEET (RULE 26) Change in position of the impact surface is too limited to be able to implement the adjustment of the distribution of the material required in some operating situations.

[0009] In particular, when distributing the material during a slope, it may happen that the uneven distribution of the material to the outlets of the distribution chamber due to the incline cannot be adequately compensated.

[0010] REPLACEMENT SHEET (RULE 26) In other operating situations, for example, during cornering of the distributor, an uneven distribution of the material to be distributed among the outlets of the distribution chamber may be desired. Current solutions cannot ensure such uneven distribution of the material to be distributed.

[0011] The object underlying the invention is therefore to improve the adaptation of the distribution of the distribution material flowing into the distribution chamber via the inlet to the outlets.

[0012] The object is achieved by a distribution device of the type mentioned at the outset, wherein the adjusting device of the distribution device according to the invention has three contact elements arranged at a distance from one another, which are each in contact with the impact surface carrier, wherein at least one contact element is movable by means of an adjusting actuator of the adjusting device for adjusting the position and / or the state of the impact surface.

[0013] The use of three contact elements results in a statically determined bearing of the impact surface support, thus preventing unintentional movements of the impact surface, which could lead to an unintentional distribution of the distribution material between the outlets. The distribution manipulator can be used, for example, to achieve an intended, particularly uneven, distribution of the distribution material between the outlets when cornering. The distribution manipulator can be used, for example, to ensure an intended, particularly even, distribution of the distribution material between the outlets when driving on slopes. The distribution manipulator can also be used, for example, to compensate for an uneven distribution of the distribution material between the outlets due to manufacturing and / or design. An uneven distribution of the distribution material between the outlets due to manufacturing tolerances and their influence on the component geometry.A design-related uneven distribution of the distribution material to the outlets can arise due to an unsuitable supply of the incoming distribution material, for example, due to a supply line that is too short, or due to different line lengths in the distribution lines connected to the outlets, since different line-length-specific backpressures arise in the distribution lines. The distribution chamber of the distribution device according to the invention can have one or more inlets through which the distribution material can flow into the distribution chamber. Preferably, two contact elements of the adjustment device are movable by actuators. Particularly preferably, all three contact elements of the adjustment device are movable by actuators.

[0014] In a preferred embodiment of the distribution device according to the invention, the position of the impact surface is variable with respect to the position and / or orientation of the impact surface. The impact surface can be tilted, inclined, or adjusted, for example, using the distribution manipulator. By tilting, inclining, or adjusting the impact surface, the direction of rebound of the material being distributed from the impact surface is changed, thus altering the distribution to the outlets. The distribution manipulator can be designed such that the axis about which the impact surface can be tilted, inclined, or adjusted is predetermined. Alternatively, the distribution manipulator can be designed such that the axis about which the impact surface can be tilted, inclined, or adjusted is freely selectable. The impact surface can also be freely movable in space. By means of the distribution manipulator, the impact surface can, for example, also perform a lifting movement.In this case, for example, a parallel adjustment of the impact surface can be carried out, whereby the impact surface can be moved, particularly in the vertical direction, into and out of the distribution chamber. The lifting movement or parallel adjustment achieves a throttling effect in the conveyor line connected to the inlet. The distribution manipulator can also be used to change the state of the impact surface with regard to the shape and / or size of the impact surface. For example, concave and / or convex surface areas can be created in the impact surface using the adjustment device, via which the rebound direction of the distributed material from the impact surface is changed, thus changing the distribution to the outlets. If the impact surface has a round basic shape, the diameter of the impact surface can be changed, for example, whereby the proportion of the distributed material rebounding from the impact surface can be changed.

[0015] The distribution device according to the invention is further advantageously developed in that the adjustment device has a first adjustment actuator, by means of which a first contact member of the adjustment device can be moved to adjust the position and / or the state of the impact surface. The adjustment device preferably has a second adjustment actuator, by means of which a second contact member of the adjustment device can be moved to adjust the position and / or the state of the impact surface. The first adjustment actuator can be an electrically, hydraulically, or pneumatically operating adjustment actuator. The second adjustment actuator can be an electrically, hydraulically, or pneumatically operating adjustment actuator.

[0016] In another preferred embodiment of the distribution device according to the invention, the adjustment device has a third adjustment actuator, by means of which a third contact element of the adjustment device can be moved to adjust the position and / or state of the impact surface. The third adjustment actuator can be an electrically, hydraulically, or pneumatically operated adjustment actuator.

[0017] The distribution device according to the invention is further advantageously developed in that the contact members are designed as plungers. Alternatively or additionally, the contact members can extend in a longitudinal direction, wherein the one or more adjustment actuators can be configured to move the contact members in the longitudinal direction. The contact members can, for example, have an elongated rod shape.

[0018] Furthermore, a distribution device according to the invention is preferred in which the one or more adjustment actuators are designed as stepper motors. The stepper motors can be used to precisely change the position and / or state of the impact surface. The stepper motors preferably have a linear guide for the contact elements.

[0019] In a further preferred embodiment of the distribution device according to the invention, the adjusting device has a contact-securing element which exerts a contact force on the impact surface carrier, by means of which the impact surface carrier is held in contact with the contact members. The contact between the impact surface carrier and the contact members is preferably free of play. The contact-securing element can be or comprise a spring, in particular a tension spring, or a bellows. Alternatively, the contact force can also be applied by the conveying air with which the material to be distributed is pneumatically conveyed, or by an air material stream which comprises the conveying air and the material to be distributed. The contact force can be a tensile force or a compressive force. The contact-securing element is preferably positively connected to the impact surface carrier.The contact securing element preferably ensures a play-free contact between the contact elements and the impact surface carrier.

[0020] In another preferred embodiment of the distribution device according to the invention, the adjustment device has an anti-rotation device for the impact surface, which prevents rotation of the impact surface about a vertical axis or at least limits it to a tolerance range. The anti-rotation device can be formed by rotation stops. Alternatively, the anti-rotation device can be implemented via a contact-locking element, for example, a bellows.

[0021] Furthermore, a distribution device according to the invention is preferred in which the impact surface carrier has one or more contact member guides, along which the one or more contact members are guided when the impact surface carrier changes position due to a movement of at least one contact member. The one or more contact member guides can be linear guides, in particular longitudinal grooves. The impact surface carrier can be an impact plate. The impact surface is located, for example, on the underside of the impact plate. The one or more contact member guides are located, for example, on the top side of the impact plate. The impact plate can be flat or conical on the top side, for example. The contact member guides can also be bent or curved.

[0022] In a further preferred embodiment of the distribution device according to the invention, the distribution chamber is located in a chamber housing, with a protective element on the side of the impact surface support facing away from the inlet defining a protective space in which the parts of the adjustment device arranged in the chamber housing are located and protected from contact with the material being distributed. The protective element can be, for example, a bellows or a flexible membrane. A return element and / or the contact element guides and / or the contact elements and / or the adjustment actuators can be partially or completely located in the protective space.

[0023] In a further preferred embodiment of the distribution device according to the invention, the adjustment device has a calibration stop, wherein the impact surface carrier can be brought into abutment with the calibration stop by moving the contact elements into a calibration position. The calibration stop allows the impact surface carrier and thus also the impact surface to be moved into a defined and known starting position. Alternatively or in addition to the calibration stop, the position of the contact elements and / or the position of the impact surface or the impact surface carrier can also be detected by sensors, so that a calibration stop is not absolutely necessary. Alternatively or in addition to the calibration stop, the one or more adjustment actuators can have a state detection function, so that a calibration stop is not absolutely necessary.

[0024] The impact surface can be flat. Alternatively, the impact surface can be concavely curved or concavely arched. Alternatively, the impact surface can be convexly curved or convexly arched. The impact surface can also be conical. The impact surface can have grain guide contours to channel the material being distributed. The grain guide contours can be ridges or grooves.

[0025] The object underlying the invention is further achieved by a distribution device of the type mentioned at the outset, wherein the plurality of outlets for distribution material flowing out of the distribution chamber are arranged around an axis and connected via distribution lines to discharge units for discharging the distribution material onto the agricultural area. The discharge units are arranged next to one another in an arrangement sequence transversely to the direction of travel, such that the discharge units or pairs of adjacent discharge units are assigned an arrangement position in the arrangement sequence. Several or all outlets and / or pairs of outlets are arranged next to one another in an outlet sequence with respect to a reference direction running through the distribution chamber, such that the outlets and / or the pairs of outlets are assigned an outlet position in the outlet sequence.The outlet position of the respective outlets or the respective pairs of outlets in the outlet order and the arrangement position of the dispensing unit connected to the respective outlet and / or the pair of adjacent dispensing units connected to the respective pair of outlets in the arrangement order coincide.

[0026] The object underlying the invention is further achieved by a distribution device of the type mentioned at the outset, wherein the plurality of outlets for distribution material flowing out of the distribution chamber are arranged around an axis and connected via distribution lines of different lengths to delivery units for discharging the distribution material onto the agricultural land. The distribution lines or pairs of distribution lines of equal length have a line length sequence according to their respective line length, so that the distribution lines or pairs of distribution lines of equal length are assigned a length position in the line length sequence. Several or all outlets and / or pairs of outlets are arranged next to one another in an outlet sequence with respect to a reference direction running through the distribution chamber, so that the outlets and / or the pairs of outlets are assigned an outlet position in the outlet sequence.The outlet position of the respective outlets or the respective pairs of outlets in the outlet sequence and the length position of the distribution line connected to the respective outlet and / or the pair of equally long distribution lines connected to the respective pair of outlets in the line length sequence are identical. Due to the positioning of the discharge units, distribution lines of different lengths are often used to supply the distribution material discharged from the distribution chamber via the outlets to the distribution units. The longer the distribution lines, the higher the backpressure emanating from the distribution line, so more distribution material is introduced into short distribution lines than into long distribution lines.This uneven distribution, which is due to the different lengths of the distribution lines, can be compensated for by favoring the outlets connected to the long distribution lines through a suitable alignment of the baffle surface by the distribution manipulator, so that the higher back pressure of the long lines is compensated by a specific baffle surface alignment.

[0027] Due to the positioning of the dispensing units and the resulting different lengths of the distribution lines, the distribution material can also be unevenly distributed among the dispensing units when a dispensing process is switched on and / or off. The longer the distribution lines, the longer it takes for the material to be distributed to travel through the respective distribution line from the respective outlet of the distribution chamber to the respective dispensing unit. When a dispensing process is switched on, the dispensing units connected to shorter distribution lines are therefore supplied with distribution material first. When a dispensing process is switched off, the supply of distribution material to the dispensing units connected to shorter distribution lines is consequently interrupted earlier.

[0028] This uneven distribution at the start and stop times of a spreading process, which is due to the different lengths of the distribution lines, can be compensated for as described below. The outlets connected to longer distribution lines are favored for a defined period of time by a suitable alignment of the impact surface by the distribution manipulator when a spreading process is activated. This compensates for the longer conveying time caused by the longer distribution lines through a specific alignment of the impact surface. Longer distribution lines are therefore supplied with the material to be distributed earlier than shorter distribution lines when a spreading process is activated, in order to achieve the desired distribution of the material to the distribution units immediately after the spreading process is activated.After the defined period of time and / or taking into account the driving speed of the distribution machine and / or taking into account the conveying speed of the material to be distributed, the preference for the longer distribution lines is gradually or completely withdrawn by the specific baffle surface alignment in order to ensure that the distribution of the material to be distributed by the delivery units begins simultaneously at all delivery units when the spreading process is switched on.

[0029] The outlets connected to shorter distribution lines are favored for a defined period of time by the distribution manipulator when a spreading process is switched off via a suitable alignment of the impact surface. This compensates for the shorter conveying time due to the shorter distribution lines through a specific alignment of the impact surface. Compared to longer distribution lines, shorter distribution lines are therefore exposed to the distribution material for a longer period of time when a spreading process is switched off. This ensures that the distribution of the distribution material by the delivery units is stopped simultaneously at all delivery units when the spreading process is switched off. This also allows the amount of material conveyed to be reduced.

[0030] This compensation of the different delivery times through distribution lines of different lengths, as described above, using suitable baffle alignments, can replace and / or supplement the tramline flaps previously used for this purpose in the state of the art for opening and closing the distribution lines. This compensation is also called V-compensation, since without it, a V-shaped application result would result from the conventional hose arrangement.

[0031] The delivery units can comprise devices for conditioning the distribution flow. By tilting or pivoting the impact surface or the impact surface support about an axis running perpendicular to the reference direction, the distribution of the distribution material in the transverse direction can be influenced. When tilting or pivoting the impact surface in a first direction, the amount of distribution material supplied to the delivery units arranged on the left is increased. The further to the left the delivery units are arranged, the more distribution material is supplied to the respective delivery units when the impact surface is tilted or pivoted in the first direction. When tilting or pivoting the impact surface in a second direction, the amount of distribution material supplied to the delivery units arranged on the right is increased.The further to the right the delivery units are arranged, the more distribution material is fed to the respective delivery units when the impact surface is tilted or pivoted in the second direction. When the impact surface is tilted or pivoted in a third direction, the amount of distribution material fed to the centrally arranged delivery units is increased. The further to the center the delivery units are arranged, the more distribution material is fed to the respective delivery units when the impact surface is tilted or pivoted in the third direction. When the impact surface is tilted or pivoted in a fourth direction, the amount of distribution material fed to the outermost delivery units is increased. The further to the outside the delivery units are arranged, the more distribution material is fed to the respective delivery units when the impact surface is tilted or pivoted in the fourth direction.

[0032] In another preferred embodiment of the distribution device according to the invention, the pairs of outlets are each formed by outlets arranged opposite one another with respect to a reference plane. In a further development, the distribution device according to the invention has a control device for controlling the one or more adjustment actuators, wherein the control device is configured to control the one or more adjustment actuators based on sensor data. The control device preferably comprises an electronic data processing device for processing the sensor data. Alternatively or additionally, the control device can be configured to control the one or more adjustment actuators based on application data relating to the agricultural area and / or the current application process.The application data relating to the agricultural area can relate to the slope of the agricultural land. The slope of the land can be derived from a map of the agricultural land or map data relating to the agricultural land. The application data relating to the current application process can, for example, relate to the tramline system and / or the current position and / or the current condition, in particular the slope condition, of the spreader and / or a vehicle carrying or pulling the spreader. The sensor data can be provided by sensors of the spreading device or by external sensors.In a further preferred embodiment, the distribution device according to the invention has one or more sensors configured to provide the sensor data, wherein the control device is configured to determine the distribution of the material to be distributed among the outlets based on the sensor data. The control of the one or more adjustment actuators based on sensor data preferably takes place depending on the determined distribution of the material to be distributed among the outlets. The control device is preferably configured to regulate a target distribution of the material to be distributed among the outlets by controlling the one or more adjustment actuators.

[0033] Furthermore, a distribution device according to the invention is preferred in which the one or more sensors are configured to determine the flow of distribution material in one or more distribution lines connected to the outlets. The distribution lines can be distribution hoses. A sensor can also be arranged on only one distribution line, so that the flow of distribution material is determined based on a sample model. Furthermore, a sensor can be arranged on several or all distribution lines. The one or more sensors can be grain counting sensors or volume flow sensors. Grain counting sensors can, for example, count the number of grains passing through the sensor per second. The sensor data can also be provided by an acceleration sensor. The acceleration data can allow the position and / or inclination of the distribution chamber to be detected.The distribution device can include a yaw rate sensor, allowing the sensor data to determine the curvature of a curve currently being negotiated. Based on the curve curvature, the distribution of the material to be distributed among the outlets can then be adjusted.

[0034] The object underlying the invention is further achieved by a method of the type mentioned at the outset, wherein the distribution manipulator, within the scope of the method according to the invention, is controlled by a control device of the distribution device, in particular based on sensor data, to adjust a target distribution of the distribution material to the outlets. By adjusting the target distribution, an intended, in particular uneven, distribution of the distribution material to the outlets is achieved during cornering. Alternatively or additionally, by adjusting the target distribution, an intended, in particular uneven, distribution of the distribution material to the outlets is achieved during a distribution run, preferably with different, in particular map-based, seeding densities.Alternatively or additionally, adjusting the target distribution ensures an intended, particularly even, distribution of the material to be distributed among the outlets during slope travel. Alternatively or additionally, adjusting the target distribution compensates for any manufacturing-related and / or design-related uneven distribution of the material to be distributed among the outlets.

[0035] The distribution manipulator is preferably controlled by controlling one or more adjustment actuators of the distribution manipulator, with the control device controlling the one or more adjustment actuators, in particular based on sensor data. Preferably, several sensors provide sensor data, with the control device determining the distribution of the material to be distributed to the outlets based on the sensor data. The adjustment device can have three contact elements arranged at a distance from one another, each of which is in contact with the impact surface carrier, with at least one contact element being movable by means of an adjustment actuator of the adjustment device to adapt the position and / or state of the impact surface. An uneven distribution of the material to be distributed to the outlets due to manufacturing tolerances and their influence on the component geometry can arise.A design-related uneven distribution of the material to be distributed among the outlets can occur due to different pipe lengths in the distribution lines connected to the outlets, as different backpressures arise in the distribution lines depending on the pipe length. The pressure in the distribution lines can also be determined by one or more pressure sensors.

[0036] In a preferred embodiment of the method according to the invention, the distribution material is guided from the outlets to delivery units for delivery of the distribution material onto the agricultural land via distribution lines connecting the delivery units to the outlets. The plurality of outlets for distribution material flowing out of the distribution chamber are arranged around an axis. Alternatively or additionally, the delivery units are arranged next to one another in an arrangement sequence transverse to the direction of travel, such that the delivery units or pairs of adjacent delivery units are assigned an arrangement position in the arrangement sequence. Alternatively or additionally, several or all outlets and / or pairs of outlets are arranged next to one another in an outlet sequence with respect to a reference direction running through the distribution chamber, such that the outlets and / or the pairs of outlets are assigned an outlet position in the outlet sequence.The outlet position of the respective outlets or the respective pairs of outlets in the outlet order and the arrangement position of the dispensing unit connected to the respective outlet and / or the pair of adjacent dispensing units connected to the respective pair of outlets in the arrangement order coincide.

[0037] In another preferred embodiment of the method according to the invention, the quantity of material to be distributed discharged from the distribution chamber through the outlets is reduced or increased by controlling the distribution manipulator. The quantity of air discharged from the distribution chamber through the outlets, and thus the air velocity, can also be reduced by controlling the distribution manipulator. For this purpose, the impact surface performs a lifting movement, for example. The lifting movement or the parallel adjustment achieves a throttling effect in the conveying line connected to the inlet. The distribution device can also comprise a plurality of distribution chambers, each of which contains a movable impact surface, wherein the impact surfaces in the plurality of distribution chambers can be kinematically coupled to one another.In a further embodiment, the discharge of material to be distributed from the distribution chamber through several or all outlets is interrupted by controlling the distribution manipulator. For example, the baffle surface is adjusted, in particular lowered, in such a way that the flow paths to the several or all outlets are blocked by the baffle surface.

[0038] In another preferred embodiment of the method according to the invention, sensor data is provided to the control device by one or more sensors, wherein the control device determines the distribution of the distribution material to the outlets based on the sensor data. The sensor data determines the distribution material flow in one or more distribution lines connected to the outlets. Alternatively or additionally, the control device can control the one or more adjustment actuators based on application data relating to the agricultural area and / or the current application process. The application data relating to the agricultural area can relate to the slope of the agricultural area. The slope of the ground can be derived from a map of the agricultural area or map data relating to the agricultural area.The application data relating to the current application process may, for example, relate to the tramline system and / or the current position and / or the current condition, in particular the inclination condition, of the spreading machine and / or a vehicle carrying or pulling the spreading machine.

[0065] Fig. 1 shows a distribution device 10 for a pneumatically operating agricultural distribution machine 100.

[0066] The distribution device 10 comprises a chamber housing 12 with a removable housing cover 14. A distribution chamber 34 is located in the chamber housing 12 below the housing cover 14, through which distribution material V flowing into the distribution chamber 34 is distributed to the outlets 16a-16t. The outlets 16a-16t are arranged around a central axis of the chamber housing 12.

[0067] The distribution device 10 comprises a distribution manipulator 18 for adjusting the distribution of the distribution material V to the outlets 16a-16t. The distribution manipulator 18 comprises a baffle 22 supported by a movable baffle support 20, which is arranged opposite an inlet 38. The distribution material V flows into the distribution chamber 34 in the chamber housing 12 via the inlet 38. The distribution material V flowing into the distribution chamber 34 strikes the baffle 22 and rebounds off the baffle 22. The distribution manipulator 18 further comprises an adjustment device 24 for changing the position of the baffle 22.

[0068] As shown in Fig. 2, the adjustment device 24 has three contact elements 26a-26c arranged at a distance from one another. The contact elements 26a-26c have an elongated rod shape and are each in contact with the impact surface support 20.

[0069] The adjustment device 24 has a first adjustment actuator 28a, by means of which the first contact member 26a of the adjustment device 24 can be moved to adjust the position of the impact surface 22. The adjustment device 24 has a second adjustment actuator 28b, by means of which the second contact member 26b of the adjustment device 24 can be moved to adjust the position of the impact surface 22. The adjustment device 24 further has a third adjustment actuator 28c, by means of which the third contact member 26c of the adjustment device 24 can be moved to adjust the position of the impact surface 22.

[0070] As shown in Figs. 3 and 4, the position and orientation of the impact surface 22 can be changed by means of the distribution manipulator 18. The adjustment actuators 28a-28c are designed as stepper motors. The contact members 26a-26c extend in a longitudinal direction, with the adjustment actuators 28a-28c being configured to move the contact members 26a-26c in the longitudinal direction. The contact members 26a-26c can thus be extended and retracted by means of the adjustment actuators 28a-28c, so that the impact surface 22 can be inclined or tilted by means of the distribution manipulator 18. By tilting or tipping the impact surface 22, the rebound direction of the material V to be distributed from the impact surface 22 is changed, so that the distribution to the outlets 16a-16t is changed.

[0071] The adjustment device 24 further comprises a contact securing element 30, which exerts a contact force on the impact surface carrier 20. The contact force holds the impact surface carrier 20 in contact with the contact elements 26a-26c. The contact between the contact elements 26a-26c and the impact surface carrier 20 is free of play. The contact securing element 30 is designed as a tension spring, so that the contact force is a tensile force.

[0072] The impact surface carrier 20 has three contact member guides 32a-32c, along which the contact members 26a-26c are guided in the event of a change in position of the impact surface carrier 20 caused by a movement of at least one contact member 26a-26c.

[0073] Figure 5 shows, using the contact element guide 32a as an example, that the contact element guides 32a-32c are linear guides, namely longitudinal grooves. The impact surface support 20 is a baffle plate. The impact surface 22 is located on the underside of the baffle plate. The contact element guides 32a-32c are located on the top side of the baffle plate.

[0074] Fig. 6 shows that the material to be distributed V is fed to the distribution chamber 34 via a supply line 36 designed as a riser. The material to be distributed V flows into the distribution chamber 34 via the inlet 38.

[0075] The baffle surface 22, arranged opposite the inlet 38, can be tilted or inclined by moving the baffle surface support 20. By tilting or inclining the baffle surface 22, the distribution of the material V flowing into the distribution chamber 34 via the inlet 38 to the outlets 16a-16t can be adjusted.

[0076] The distribution device 10 has a control device 50 for controlling the adjustment actuators 28a-28c. The control device 50 is configured to control the adjustment actuators 28a-28c based on sensor data. The control device 50 includes an electronic data processing device for processing the sensor data. The sensor data can be provided by sensors of the distribution device 10 or by external sensors.

[0077] Figures 7 and 8 show impact plates, each with three contact element guides 32a-32c. The contact element guides 32a-32c are designed as elongated radial grooves. In the center of the impact surface support 20 is a hooking element into which a tension spring used as a contact securing element 30 can be hooked.

[0078] The impact surface support shown in Fig. 7 has a flat top surface. The impact surface support 20 shown in Fig. 8 has a conical top surface.

[0079] In the distribution device 10 shown in Fig. 9, the contact securing element 30 is designed as a circumferential bellows. The bellows also acts as an anti-rotation device for the impact surface 22 and prevents rotation of the impact surface 22 about a vertical axis. Furthermore, the circumferential bellows acts as a protective element 40, which defines a protective area 42 on the side of the impact surface support 20 facing away from the inlet 28. Parts of the adjustment device 24 are located within this protective area and are protected from contact with the material V being distributed.

[0080] Fig. 10 shows that the contact elements 26a-26c are arranged in sections in the protective space 42 delimited by the protective element 40.

[0081] Fig. 11 shows a baffle support 20 with a convexly curved baffle 22 in a sectional view running through the longitudinal axis.

[0082] Fig. 12 shows a baffle support 20 with a conical baffle 22.

[0083] Fig. 13 shows a baffle support 20 with a concave baffle surface 22 in a sectional view running through the longitudinal axis.

[0084] Fig. 14 shows a baffle support 20 with a conical baffle 22, wherein the baffle 22 has radially extending grooves through which the material to be distributed V can be channeled. Fig. 15 shows a distribution device 10 in which the outlets 16a-16t are arranged around an axis A and are connected via distribution lines 44a-44t to discharge units 46a-46t for discharging the material to be distributed V onto the agricultural land.

[0085] The chamber housing 12 has an inclination a. The inclination a of the chamber housing 12 occurs without the distribution machine 100 or the carrier machine 200 being aligned at an inclination. Such an inclination can occur, for example, due to manufacturing tolerances, faulty assembly, or damage to the distribution device 12.

[0086] The inclination a of the chamber housing 12 would, without suitable compensation, lead to the distribution material V being distributed unevenly between the outlets 16a-16t.

[0087] Fig. 16 shows that the actual distribution IV of the distribution material V is uneven if the inclination a of the chamber housing 12 is not compensated by a distribution manipulator 18 of the distribution device 10. The inclination a of the chamber housing 12 results in more distribution material V being supplied to the downwardly inclined outlets 16j, 16k than the uniform target distribution SV provides. Accordingly, less distribution material V is supplied to the upwardly inclined outlets 16a, 16t than the target distribution SV provides.

[0088] By setting a suitable inclination of the impact surface 22 via the adjustment actuators 28a-28c, the inclination a of the chamber housing 12 can be compensated so that an intended uniform target distribution SV is again established.

[0089] Fig. 17 shows that, if the distribution machine 100 and the carrier machine 200 are tilted laterally and no countermeasures are taken, an actual distribution IV of the distribution material V is established, in which more distribution material V is supplied to the downslope outlets than the uniform target distribution SV provides for, and less distribution material V is supplied to the upslope outlets than the uniform target distribution SV provides for. By tilting or tipping the impact surface carrier 20 carrying the impact surface 22, the distribution of the distribution material V can be adjusted such that the intended uniform target distribution SV is achieved despite the inclination of the distribution machine 100 and the carrier machine 200.

[0090] Fig. 18 shows a machine combination comprising carrier machine 200 and distribution machine 100 traveling uphill. In this application scenario, too, more distribution material V is supplied to the downhill outlets than the uniform target distribution SV envisages. Less distribution material G is supplied to the uphill outlets than the uniform target distribution SV envisages. In this case, too, a balancing effect can be achieved by tilting or inclining the impact surface 22, which restores the intended uniform target distribution SV, even though the carrier machine 200 and the distribution machine 100 are inclined due to traveling uphill.

[0091] Fig. 19 shows a machine combination consisting of carrier machine 200 and distribution machine 100 during a curve. Depending on the curve radius r and the travel speed of the carrier machine 200, different speeds vi, VM, V are set transversely to the direction of travel FR.A during cornering. The speed VM can, for example, refer to the travel speed of the carrier machine 200. Due to the curve radius, the speed vi on the inside lane is lower than the speed v M . Furthermore, the speed v A on the outside lane due to cornering higher than the speed v M .

[0092] Due to the different track speeds during cornering, more distribution material V must be supplied to the delivery units on the outside of the curve than to the delivery units on the inside of the curve in order to achieve a uniform deposition pattern on the agricultural land. To achieve this, a larger quantity of distribution material V must be supplied to the outlets connected to the delivery units on the outside of the curve than to the outlets connected to the delivery units on the inside of the curve. For this purpose, the distribution manipulator 18 of the distribution device 10 is controlled by a control device 50 to adjust a suitable target distribution SV1, SV2 of the distribution material V to the outlets 16a-16t. Fig. 20 shows the target distribution SV1, which is to be adjusted for a left-hand bend, and the target distribution SV2, which is to be adjusted for a right-hand bend.By adjusting the target distributions SV1, SV2, an intended uneven distribution of the distribution material V to the outlets 18a-18t is achieved during cornering.

[0093] The distribution device 10 shown in Fig. 20 shows that the outlets 16a-16t for the distribution material V flowing out of the distribution chamber 34 are arranged around an axis A. The outlets 16a-16t are connected via distribution lines 44a-44t to discharge units 46a-46t for discharging the distribution material V onto the agricultural land.

[0094] The distribution device 10 further comprises a plurality of sensors 48a-48t, which are configured to provide sensor data to the control device 50. The control device 50 uses the sensor data to determine the distribution of the distribution material V to the outlets 16a-16t. The sensors 48a-48t are grain counting sensors and determine the distribution material flows in the distribution lines 44a-44t connected to the outlets 16a-16t.

[0095] The delivery units 46a-46t are arranged next to each other transversely to the direction of travel FR in an arrangement sequence RF1. Pairs of adjacent delivery units 46a-46t can thus be assigned an arrangement position AN1-AN10 in the arrangement sequence RF1. This results in the following assignment:

[0096] AN1 = 46a + 46b

[0097] AN2 = 46c + 46d

[0098] AN3 = 46e + 46f

[0099] AN4 = 46g + 46h

[0100] AN5 = 46i + 46j

[0101] AN6 = 46k + 46I

[0102] AN7 = 46m + 46n

[0103] AN8 = 46o + 46p

[0104] AN9 = 46q + 46r

[0105] AN10 = 46s + 46t Pairs of outlets 16a-16t are arranged side by side in an outlet sequence RF2 with respect to a reference direction RR running through the distribution chamber 34. The pairs of outlets 16a-16t can thus be assigned an outlet position AU1-AU10 in the outlet sequence RF2. The assignment is as follows:

[0106] AU1 = 16e + 16f

[0107] AU2 = 16d + 16g

[0108] AU3 = 16c + 16h

[0109] AU4 = 16b + 16i

[0110] AU5 = 16a + 16j

[0111] AU6 = 16t + 16k

[0112] AU7 = 16s + 161

[0113] AU8 = 16r + 16m

[0114] AU9 = 16q + 16n

[0115] AU10 = 16p + 16o

[0116] The outlet position AU1-AU10 of the respective pairs of outlets 16a-16t in the outlet order RF2 and the arrangement position AN1-AN10 of the pair of adjacent discharge units 46a-46t connected to the respective pair of outlets 16a-16t in the arrangement order RF1 coincide.

[0117] Fig. 21 shows the assignment of the pairs of outlets 16a-16t and the pairs of dispensing units 46a-46t based on the outlet positions AU1-AU10 and the arrangement positions AN1-AN10.

[0118] Fig. 22 shows the uniform actual distribution IV of the distribution material V to the outlets 16a-16t, provided that no adjustment of the distribution of the distribution material is carried out by means of the manipulator 18. By tilting the impact surface support 20 comprising the impact surface 22 about the tilting axis KA running perpendicular to the reference direction RR, the illustrated target distributions SV1, SV2 can be achieved with the explained assignment of the outlets 16a-16t and the discharge units 46a-46t, via which the different track speeds are compensated when negotiating a curve.

[0119] Figs. 23 and 24 show an alternative arrangement of the outlets 16a-16t and the delivery units 46a-46t, by means of which an intended uneven distribution of the distribution material V to the outlets 16a-16t can also be achieved during cornering, by means of which a uniform row-related sowing rate can be achieved during cornering.

[0120] In the assignment shown in Fig. 23, the reference direction RR runs opposite to the reference direction RR shown in Figs. 21 and 22. This results in the following outlet assignments:

[0121] AU1 = 16p + 16o

[0122] AU2 = 16q + 16n

[0123] AU3 = 16r + 16m

[0124] AU4 = 16s + 161

[0125] AU5 = 16t + 16k

[0126] AU6 = 16a + 16j

[0127] AU7 = 16b + 16i

[0128] AU8 = 16c + 16h

[0129] AU9 = 16d + 16g

[0130] AU10 = 16e + 16f

[0131] Fig. 23 again shows the uniform actual distribution IV of the distribution material V to the outlets 16a-16t, provided that no adjustment of the distribution material is made by means of the manipulator 18. By tilting the impact surface support 20 comprising the impact surface 22 about the tilting axis KA running perpendicular to the reference direction RR, the depicted target distributions SV1, SV2 can be achieved even with this assignment of the outlets 16a-16t and the delivery units 46a-46t, via which the different track speeds are compensated when negotiating a curve.

[0132] The distribution device 10 shown in Fig. 25 also shows that the outlets 16a-16t for the distribution material flowing out of the distribution chamber 34

[0133] V are arranged around an axis A. The outlets 16a-16t are connected via distribution lines 44a-44t to discharge units 46a-46t for discharging the distribution material

[0134] V to the agricultural land. The distribution lines 44a-44t have different lengths.

[0135] Fig. 25 shows the uneven actual distribution IV of the distribution material V to the outlets 16a-16t, which is due to the different line lengths of the distribution lines 44a-44t, unless the distribution of the distribution material is adjusted by means of the manipulator 18. As the line length increases, a decreasing amount of distribution material V is discharged from the distribution chamber 34 through the outlet 16a-16t connected to the respective distribution line 44a-44t due to back pressure.

[0136] By tilting the impact surface support 20 comprising the impact surface 22 about the tilting axis KA running perpendicular to the reference direction RR (cf. Fig. 26), the uniform target distribution SV shown can be achieved despite different line lengths with the assignment of the outlets 16a-16t and the distribution lines 44a-44t explained below.

[0137] The distribution lines 44a, 44t connected to the front outlets 16a, 16t in the direction of travel FR are the longest. The distribution lines 44j, 44k connected to the rear outlets 16j, 16k in the direction of travel FR are the shortest. Pairs of equally long distribution lines 44a-44t have the following line length sequence according to their respective line lengths, with the line length decreasing with increasing length position L1-L10 in the line length sequence:

[0138] L1 = 44a + 44t

[0139] L2 = 44b + 44s

[0140] L3 = 44c + 44r

[0141] L4 = 44d + 44q

[0142] L5 = 44e + 44p L6 = 44f + 44o L7 = 44g + 44n L8 = 44h + 44m L9 = 44i + 44I L10 = 44j + 44k

[0143] Pairs of outlets 16a-16t are arranged side by side in an outlet sequence RF2 with respect to a reference direction RR running through the distribution chamber 34 and pointing opposite to the direction of travel FR. The pairs of outlets 16a-16t can thus be assigned an outlet position AU1-AU10 in the outlet sequence RF2. The assignment is as follows: AU1 = 16a + 16t

[0144] AU2 = 16b + 16s

[0145] AU3 = 16c + 16r

[0146] AU4 = 16d + 16q

[0147] AU5 = 16e + 16e

[0148] AU6 = 16f + 16o

[0149] AU7 = 16g + 16n

[0150] AU8 = 16h + 16m

[0151] AU9 = 16i + 161

[0152] AU10 = 16j + 16k

[0153] The outlet position AU1-AU10 of the respective pairs of outlets 16a-16t in the outlet sequence RF2 and the length position L1-L10 of the pair of equal-length distribution lines 44a-44t connected to the respective pair of outlets 16a-16t in the line length sequence match.

[0154] The arrangement of the distribution lines 44a-44t shown in Fig. 25 also makes it possible to compensate for an uneven distribution of the distribution material V at the switching-on and switching-off times of a spreading process, which is due to the different line lengths of the distribution lines 44a-44t, by tilting the impact surface support 20 comprising the impact surface 22 about the tilting axis KA running perpendicular to the reference direction RR.

[0155] The longer the distribution lines 44a-44t are, the longer the conveying time of the distribution material V to reach the respective delivery unit 46a-46t through the respective distribution line 44a-44t from the respective outlet 16a-16t of the distribution chamber 34.

[0156] Thus, when a spreading process is switched on, for example, the dispensing unit 46j, which is connected to a short distribution line 44j, is supplied with distribution material V earlier than the dispensing unit 46a, which is connected to a long distribution line 44a. Furthermore, when a spreading process is switched off, for example, the dispensing unit 46a, which is connected to the long distribution line 44a, is supplied with distribution material V for a longer time than the dispensing unit 46j, which is connected to the short distribution line 44j.By means of a suitable alignment of the impact surface 22 by means of the distribution manipulator 18 in the direction of the outlet positions A1-A5, to which the length positions L1-L5 are assigned, in particular temporarily set at the start of a spreading process, the longer conveying time due to the longer line length can be compensated by a specific impact surface alignment when switching on a spreading process in order to achieve a desired distribution of the distribution material directly when switching on a spreading process.

[0157] V across all delivery units 46a-46t.

[0158] By means of a suitable alignment of the impact surface 22 by means of the distribution manipulator 18 in the direction of the outlet positions A6-A10, to which the length positions L6-L10 are assigned, in particular temporarily when a spreading process is ended, the shorter conveying time due to the shorter line length can be compensated by a specific baffle surface alignment when switching off a spreading process in order to ensure a desired distribution of the distribution material even when switching off a spreading process

[0159] V across all dispensing units 46a-46t. The procedure proposed for starting and stopping the dispensing process is also called V compensation.

[0160] Fig. 26 shows the assignment of the pairs of outlets 16a-16t and the pairs of distribution lines 44a-44t based on the outlet positions AU1-AU10 and the length positions L1-L10.
