Description

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

The distribution device of agricultural distribution machines usually has an internal distribution chamber into which distribution material can be introduced via an inlet. The distribution material introduced into the distribution chamber is then discharged from the distribution chamber again via several outlets.

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

The distribution manipulator can, for example, have an impact surface supported by a movable impact surface carrier, which is arranged opposite the inlet of the distribution chamber, so that distribution material flowing into the distribution chamber hits the impact surface and bounces off the impact surface. The position of the impact surface can then be changed, for example, by means of an adjustment device in order to adapt the distribution.

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 too limited due to the limited options for changing the position of the impact surface to be able to implement the adjustment of the distribution of the distribution material required in some operating situations. In particular, when distributing the distribution material during a slope, it can happen that the uneven distribution of the distribution material to the outlets of the distribution chamber due to the incline cannot be compensated sufficiently.

In other operating situations, for example when the distribution machine is cornering, an uneven distribution of the distribution material to the outlets of the distribution chamber may be intended. The known solutions cannot currently guarantee such an uneven distribution of the distribution material.

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.

The object is achieved by a distribution device of the type mentioned at the outset, wherein the adjustment 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 adjustment actuator of the adjustment device for adjusting the position and/or the state of the impact surface.

The use of three contact elements results in a statically determined bearing of the impact surface support, so that unintentional movements of the impact surface, which lead to an unintentional distribution of the distribution material to the outlets, are avoided. The distribution manipulator can be used, for example, to achieve an intended, in particular uneven, distribution of the distribution material to the outlets when cornering. The distribution manipulator can be used, for example, to ensure an intended, in particular even, distribution of the distribution material to the outlets when driving on a slope. The distribution manipulator can also be used, for example, to compensate for an uneven distribution of the distribution material to the outlets due to production and/or design. An uneven distribution of the distribution material to the outlets due to production can occur 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 counterpressures 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 material to be distributed can flow into the distribution chamber. Preferably, two contact elements of the adjustment device can be moved by actuators. Particularly preferably, all three contact elements of the adjustment device can be moved by actuators.

In a preferred embodiment of the distribution device according to the invention, the position of the impact surface can be changed in relation to the position and/or the orientation of the impact surface. The impact surface can be inclined, tipped or adjusted using the distribution manipulator, for example. By inclining, tipping and adjusting the impact surface, the direction of rebound of the material to be distributed is determined. from the impact surface, so that the distribution to the outlets is changed. The distribution manipulator can be designed in such a way that the axis about which the impact surface can be inclined, tilted or adjusted is predetermined. Alternatively, the distribution manipulator can be designed in such a way that the axis about which the impact surface can be inclined, tilted or adjusted can be freely selected. The impact surface can also be freely moved in space. The distribution manipulator can, for example, also carry out a lifting movement. In this case, for example, a parallel adjustment of the impact surface can take place, in which the impact surface can be moved, in particular 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 in relation 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 direction of the material being distributed bounces off the impact surface, so that the distribution to the outlets is changed. If the impact surface has a round basic shape, the diameter of the impact surface can be changed, for example, which means that the proportion of the material being distributed bouncing off the impact surface can be changed.

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 adapt 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 adapt 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.

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 member of the adjustment device can be moved to adapt the position and/or the state of the impact surface. The third adjustment actuator can be an electrically, hydraulically or pneumatically operating adjustment actuator.

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 designed to move the contact members in the longitudinal direction. The contact members can, for example, have an elongated rod shape.

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 bring about a precise change in the position and/or state of the impact surface. The stepper motors preferably have a linear guide for the contact elements.

In a further preferred embodiment of the distribution device according to the invention, the adjustment 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. The contact force can alternatively also be applied by the conveying air with which the distribution material is pneumatically conveyed, or an air material flow which comprises the conveying air and the distribution material. The contact force can be a tensile force or a compressive force. The contact securing element is preferably connected to the impact surface carrier in a form-fitting manner. The contact securing element preferably ensures free of play contact between the contact members and the impact surface carrier.

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

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 in the event of a change in position of the impact surface carrier caused by 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.

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 carrier facing away from the inlet delimiting a protective space in which the parts of the adjustment device arranged in the chamber housing are located and are protected from contact with the material to be 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.

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 members into a calibration position. The calibration stop can be used to move the impact surface carrier and thus also the impact surface into a defined and known starting position. Alternatively or in addition to the calibration stop, the position of the contact members 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, so that a calibration stop is not absolutely necessary.

The impact surface can have a flat shape. 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 grooves or ridges.

The object underlying the invention is further achieved by a distribution device of the type mentioned at the outset, wherein the multiple outlets for distribution material flowing out of the distribution chamber are arranged around an axis and are connected via distribution lines to delivery units for delivering the distribution material to the agricultural area. The delivery units are arranged next to one another in an arrangement sequence transversely to the direction of travel, so that the delivery units or pairs of adjacent delivery 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, 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 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.

The object underlying the invention is further achieved by a distribution device of the type mentioned at the outset, wherein the multiple outlets for distribution material flowing out of the distribution chamber are arranged around an axis and are connected via distribution lines of different lengths to delivery units for delivering the distribution material to the agricultural area. 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 distribution lines of the same length connected to the respective pair of outlets in the line length sequence match. Due to the positioning of the delivery units, distribution lines of different lengths are often used to feed the distribution material discharged from the distribution chamber via the outlets to the distribution units. The longer the distribution lines, the higher the counterpressure emanating from the distribution line, so that more distribution material is fed into short distribution lines than into long distribution lines. This is due to the different line lengths of the distribution lines. Uneven distribution can be compensated by favoring the outlets connected to the long distribution lines through a suitable alignment of the impact surface by the distribution manipulator, so that the higher back pressure of the long lines is compensated by a specific impact surface alignment.

The delivery units can comprise devices for conditioning the distribution flow. By tilting or pivoting the impact surface or the impact surface carrier about an axis running perpendicular to the reference direction, the distribution of the distribution material in the transverse direction can thus 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 supplied to the respective delivery units when the impact surface is tilted or pivoted in the second direction. When the impact surface is tilted or swiveled in a third direction, the amount of distribution material supplied to the centrally arranged delivery units is increased. The further centrally the delivery units are arranged, the more distribution material is supplied to the respective delivery units when the impact surface is tilted or swiveled in the third direction. When the impact surface is tilted or swiveled in a fourth direction, the amount of distribution material supplied to the externally arranged delivery units is increased. The further outwards the delivery units are arranged, the more distribution material is supplied to the respective delivery units when the impact surface is tilted or swiveled in the fourth direction.

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 in relation 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 set up 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 set up 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 inclination of the ground of the agricultural area. The inclination 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 can, for example, relate to the tramline system and/or the current position and/or the current state, in particular the inclination state, of the distribution machine and/or of a vehicle carrying or pulling the distribution machine. The sensor data can be provided by sensors of the distribution device or by external sensors.

In a further preferred embodiment, the distribution device according to the invention has one or more sensors which are designed to provide the sensor data, wherein the control device is designed to determine the distribution of the material to be distributed to 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 to the outlets. The control device is preferably designed to regulate a target distribution of the material to be distributed to the outlets by controlling the one or more adjustment actuators.

A distribution device according to the invention is also preferred in which the one or more sensors are set up 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 just one distribution line, so that the flow of distribution material is determined using 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 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 recorded. The distribution device can comprise a yaw rate sensor, so that the curvature of a curve currently being traveled can be determined using the sensor data. The curve curvature can be used to then the distribution of the material to be distributed to the outlets must be adjusted.

The object underlying the invention is further achieved by a method of the type mentioned at the outset, wherein the distribution manipulator is controlled in the context of the method according to the invention by means of a control device of the distribution device, in particular based on sensor data, to regulate 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 sowing intensities, in particular map-based. Alternatively or additionally, by adjusting the target distribution, an intended, in particular even, distribution of the distribution material to the outlets is ensured during a slope run. Alternatively or additionally, an uneven distribution of the material to be distributed to the outlets due to manufacturing and/or design is compensated for by adjusting the target distribution.

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 the 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. A design-related uneven distribution of the material to be distributed to the outlets can occur due to different line lengths in the distribution lines connected to the outlets, as different line-length-specific counterpressures arise in the distribution lines. The pressure in the distribution lines can also be determined by one or more pressure sensors.

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 area via distribution lines connecting the delivery units to the outlets. The multiple 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, so 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, 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 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.

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

In another preferred embodiment of the method according to the invention, sensor data for the control device are provided 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 determine 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 on the basis of 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 inclination of the ground on the agricultural area. The inclination 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 can relate, for example, to the tramline system and/or the current position and/or the current state, in particular the inclination state, of the distribution machine and/or of a vehicle carrying or towing the distribution machine.

The 1 shows a distribution device 10 for a pneumatically operating agricultural distribution machine 100.

The distribution device 10 comprises a chamber housing 12 with a removable housing cover 14. Below the housing cover 14, a distribution chamber 34 is located in the chamber housing 12, via 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.

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 an impact surface 22 carried by a movable impact surface carrier 20, which is arranged opposite an inlet 38, wherein 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 impact surface 22 and bounces off the impact surface 22. The distribution manipulator 18 further comprises an adjustment device 24 for changing the position of the impact surface 22.

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

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 also 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.

As in the 3 and 4 As shown, the position of the impact surface 22 can be changed by means of the distribution manipulator 18 in relation to the position and orientation of the impact surface 22. The adjustment actuators 28a-28c are designed as stepper motors. The contact members 26a-26c extend in a longitudinal direction, wherein the adjustment actuators 28a-28c are set up to move the contact members 26a-26c in the longitudinal direction. The contact members 26a-26c can therefore 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 inclining or tilting the impact surface 22, the direction in which the distribution material V bounces off the impact surface 22 is changed, so that the distribution to the outlets 16a-16t is changed.

The adjustment device 24 further comprises a contact securing element 30, which exerts a contacting force on the impact surface carrier 20. The contacting force keeps 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 contacting force is a tensile force.

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.

The 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 carrier 20 is an impact plate. The impact surface 22 is located on the underside of the impact plate. The contact element guides 32a-32c are located on the top side of the impact plate.

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

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

The distribution device 10 has a control device 50 for controlling the adjustment actuators 28a-28c. The control device 50 is designed to control the adjustment actuators 28a-28c using sensor data. The control device 50 comprises 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.

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

The one in the 7 The impact surface carrier shown is flat on the top. The 8 The illustrated impact surface support 20 is conical on the upper side.

In the 9 In the distribution device 10 shown, the contact securing element 30 is designed as a circumferential bellows. The bellows also acts as a rotation lock for the impact surface 22 and prevents the impact surface 22 from rotating about a vertical axis. In addition, the circumferential bellows acts as a protective element 40, which delimits a protective area 42 on the side of the impact surface carrier 20 facing away from the inlet 28, in which parts of the adjustment device 24 are located and are protected from contact with the material V to be distributed.

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

The 11 shows a baffle carrier 20 with a convexly curved baffle 22 in a sectional view running through the longitudinal axis.

The 12 shows a baffle carrier 20 with a conical baffle 22.

The 13 shows a baffle carrier 20 with a concave baffle surface 22 in a sectional view running through the longitudinal axis.

The 14 shows a baffle carrier 20 with a conical baffle 22, wherein the baffle 22 has grooves running in the radial direction, via which the material V to be distributed can be channeled.

The 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 delivery units 46a-46t for delivering the distribution material V to the agricultural area.

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

Without suitable compensation, the inclination α of the chamber housing 12 would result in the material to be distributed V being unevenly distributed between the outlets 16a-16t.

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

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

The 17 shows that if the distribution machine 100 and the carrier machine 200 are inclined sideways 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 outlets located downhill than the uniform target distribution SV provides for and less distribution material V is supplied to the outlets located uphill than the uniform target distribution SV provides for.

By inclining or tipping the impact surface carrier 20 carrying the impact surface 22, the distribution of the material to be distributed V can be adjusted in such a way that the intended uniform target distribution SV is achieved despite the inclination of the distribution machine 100 and the carrier machine 200.

The 18 shows a machine combination moving uphill consisting of carrier machine 200 and distribution machine 100. In this application scenario, more distribution material V is fed to the outlets located downhill than the uniform target distribution SV. Less distribution material G is supplied to the outlets located uphill than the uniform target distribution SV provides. In this case too, a balancing effect can be achieved by tilting or inclining the impact surface 22, through which the intended uniform target distribution SV is again established, although the carrier machine 200 and the distribution machine 100 are inclined due to travel uphill.

The 19 shows a machine combination consisting of carrier machine 200 and distribution machine 100 during cornering. Depending on the curve radius r and the travel speed of the carrier machine 200, different speeds v _I , v _M , v _A arise transversely to the direction of travel FR during cornering. The speed v _M can, for example, affect the travel speed of the carrier machine 200. Due to the curve radius, the speed v _I on the inner lane is lower than the speed v _M . Furthermore, the speed v _A on the outer lane is higher than the speed v _M due to cornering.

Due to the different track speeds when 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, so that a uniform deposition pattern is achieved on the agricultural area. In order to implement 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 means of a control device 50 to regulate a suitable target distribution SV1, SV2 of the distribution material V to the outlets 16a-16t.

The 20 shows the target distribution SV1, which is to be adjusted when cornering left, and the target distribution SV2, which is to be adjusted when cornering right. By adjusting the target distributions SV1, SV2, an intended uneven distribution of the distribution material V to the outlets 18a-18t is achieved when cornering.

The 20 The distribution device 10 shown 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 delivery units 46a-46t for delivering the distribution material V to the agricultural area.

The distribution device 10 further comprises a plurality of sensors 48a-48t, which are designed 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.

The 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 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 target distributions SV1, SV2 shown can also be achieved with this assignment of the outlets 16a-16t and the delivery units 46a-46t, via which the different track speeds are compensated when driving around a curve.

The 25 The distribution device 10 shown also 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 delivery units 46a-46t for delivering the distribution material V to the agricultural area. The distribution lines 44a-44t have different line lengths.

The 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, provided that the distribution of the distribution material is not adjusted using 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.

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. 26 ), with the assignment of the outlets 16a-16t and the distribution lines 44a-44t as explained below, the uniform target distribution SV shown can be achieved despite different line lengths.
