[0002] Agricultural cross-processing device with special intervention sections

[0003] The invention relates to an agricultural transverse tillage device for tilling vegetation between crops in a row of plants, comprising at least two tillage tools movable in a transverse direction and at least one drive, wherein the tillage tools are movable via the drive between at least one open position and one closed position, wherein each tillage tool has an engagement section for engaging the subsoil, wherein the engagement sections are arranged to extend through the surface of the subsoil.

[0004] The invention also relates to a method for treating vegetation between crops in a row of plants.

[0005] The agricultural transverse tillage equipment and methods described above are used to prevent, remove, destroy, or inhibit disruptive vegetation in agricultural areas with rows of plants. For this purpose, the transverse tillage equipment is moved along a main direction of movement along the row of plants, removing, damaging, or disrupting the vegetation in such a way as to reduce its negative impact on the crops. To achieve this, tillage tools engage with the subsoil and move the soil and vegetation by moving them along the main direction of movement and along the transverse direction. The transverse direction is essentially perpendicular to the main direction of movement and preferably lies in the same horizontal plane as the main direction of movement.

[0006] EP 3 610 712 A1 discloses such a transverse cultivation device, wherein two cultivation tools are arranged on external supports. When the cultivation tools are moved apart shortly before a crop in the row, a shaft is pivoted, thereby moving horizontal parts of the cultivation tool away from the crop in a transverse direction. This uproots or severely damages smaller vegetation and weeds. However, more deeply rooted or flexible weeds may be able to resist or evade the horizontally oriented parts. This leads to insufficient cultivation of the vegetation, which can impair the growth of the crops. Furthermore, particularly resistant vegetation may, despite being uprooted, sometimes re-root and continue to grow in essentially the same location. The object of the invention is therefore to enable improved cultivation of the vegetation.

[0007] This problem is solved according to the invention by assembling the engagement sections of the machining tools along the transverse direction in the closed position and moving the engagement sections apart in the open position.

[0008] It is also solved by moving an agricultural transverse tillage device along the row of plants and by having at least one tillage tool of the transverse tillage device till the subsoil, wherein an engagement section of the tillage tool extends through the surface of the subsoil and is moved several times between a closed position and an open position, wherein the engagement section is arranged in the area of ​​the row of plants in the closed position and is deflected out of the row of plants to one side of the row of plants in the open position, wherein the tillage tool is always deflected to the same side in the open position.

[0009] In the closed position, each section of the cutting mechanism is located near the center line, i.e., within the row of plants. Moving the cutting mechanism from the closed to the open position effectively pushes vegetation out of the row. This improved pushing action is achieved because the cutting mechanism can grasp both the vegetation within and outside the soil. The vegetation is thus pushed out of the row and into the spaces between the rows, where it lies between them. There, it can be much more easily and cost-effectively treated using conventional methods, resulting in more efficient weed control.

[0010] The inventive method also achieves more efficient weed control. By positioning the engagement section in the area of ​​the plant row, i.e., in the area of ​​the center line, or beyond the plant row in the closed position, it is ensured that as much weed as possible can be removed during the movement into the open position. This, in combination with the movement always being in the same direction, prevents weeds from being mistakenly carried towards the plant row by changes in direction.

[0011] The surface of the subsoil refers to the surface of the ground.

[0012] Preferably, the cultivation tool is designed to pass each crop in the row in the open position. This prevents the crop from being damaged by the cultivation tool in the closed position or during its movement.

[0013] The processing tool is designed to work the substrate and thus the vegetation, particularly when in the closed position, specifically to disturb or move it. This occurs especially while the transverse processing unit is moving along the main direction of movement. The processing tool is designed to engage the substrate and thus, by moving the tool, to disturb or move it. This results in damage, removal, or killing of the vegetation.

[0014] The term "assembled" means that the engagement sections are arranged in close proximity to each other in the closed position. It is primarily important that they are arranged in close proximity to each other along the transverse direction. Preferably, however, they are also arranged in close proximity along the main direction of movement. Preferably, the engagement sections are opposite each other in the closed position.

[0015] In other words, "assembled" means that the intervention sections are arranged next to each other and / or next to each other in the closed position.

[0016] In the closed position, the engagement section is preferably arranged transversely at the level of a centerline of the transverse processing device or beyond this centerline. The centerline is parallel to the main direction of movement, and the row of plants typically extends along it.

[0017] It is possible for the engagement sections to be arranged offset from one another along the main direction of movement in the closed position. However, it is advantageous if they are arranged at the same height along the main direction of movement in the closed position.

[0018] It may be provided that a gap or distance is arranged between the two engagement sections, or that the engagement sections touch each other. It may also be provided that the engagement sections at least partially cross each other in the closed position.

[0019] In normal operating conditions, the intervention section extends through the surface of the subsoil. Therefore, part of the intervention section is located above the subsoil and part is located within the subsoil.

[0020] The engagement section is typically arranged essentially perpendicular to the substrate in its intended operating position. This allows for easy alignment, enabling it to extend easily through the substrate surface. It is also possible for at least one engagement section to be positioned at an angle to the substrate in its intended operating position. Preferably, at least one engagement section extends along a vertical axis of the transverse machining device, and particularly preferably essentially parallel to this vertical axis.

[0021] The working sections are further apart in the open position than in the closed position. This ensures that weeds are pushed away from the crop row by the movement of the working tools from the closed to the open position. This efficiently removes weeds from the crop, leaving only the crop plants undamaged. If only one working tool is used, the working section is deflected away from the crop row, thus remaining spaced away from the crop row and not damaging the crop plants.

[0022] It may be provided that only one or both machining tools are moved from the closed position in a transverse direction away from the other machining tool into the open position.

[0023] Preferably, the engagement sections are arranged at the same height along a main direction of movement of the transverse processing device.

[0024] The drive may be designed to move both machining tools simultaneously from the closed position to the open position and / or from the open position to the closed position, and / or the drive may be designed to move both machining tools from the closed position to the open position and / or from the open position to the closed position with a time offset.

[0025] The drive is designed to move at least one machining tool between the open and closed positions. A single drive can be used for two or more machining tools, or individual machining tools can have their own drives or drive units within a single drive. For example, to move the machining tools from the closed to the open position, the drive can move them horizontally or diagonally upwards.

[0026] The drive can be configured to move the processing tool linearly in the transverse direction. Alternatively, the processing tool can be pivoted, for example, in a circular segment. It can be provided that at least one processing tool has at least one blade. Preferably, at least a portion of the engagement section and / or at least a portion of the recirculation section can be configured as a blade. By blade, we mean that at least one edge, for example, the leading edge, has a cutting edge designed to shred or cut vegetation.

[0027] Preferably, the processing tool passes through the row of plants on its way from the closed position to the open position. In other words, the processing tool is in the closed position on one side and in the open position on the other. This is particularly advantageous when only one processing tool is provided per row of plants.

[0028] The transverse processing device may be designed to have two processing tools, with one tool deflected to one side of the plant row and the other to the opposite side when in the open position. This allows for the most thorough processing of the plant row possible.

[0029] It is particularly advantageous if a transverse processing device according to the invention is used for carrying out the method according to the invention.

[0030] Preferably, the distance between the engagement sections of the processing tools in the closed position along the transverse direction, preferably at least in the area facing the substrate, is less than 5 cm, preferably less than 3 cm, and particularly preferably less than 1.5 cm. This ensures that the most significant area is cleared of vegetation. The distance can be the absolute distance between the engagement sections or the distance along the transverse direction, especially if the engagement sections are offset from each other along the main direction of movement. The "area facing the substrate" refers to the area that, in the intended operating position, faces the substrate. It is thus the area that extends through the surface of the substrate. Preferably, this area is no higher than 5 cm along the vertical axis A, and particularly preferably no higher than 3 cm.

[0031] It may be provided that the engagement sections of the machining tools abut each other in the closed position. "Abutting each other" in this context means that there is no significant gap between the engagement sections. It is sufficient if the engagement sections abut each other at only one point, preferably at least in the area facing the substrate. It may also be provided that only the edges of the engagement sections abut each other.

[0032] Furthermore, it is advantageous if the leading edges of the engagement sections, when closed, at least partially abut each other. Leading edges refer to the edges that point in the main direction of movement. This allows the vegetation to be moved outwards from the row of plants on both sides.

[0033] Preferably, the engagement sections and / or the parts of the processing tools that connect to the engagement sections above the surface of the substrate converge in the closed position towards the substrate, preferably forming an angle of at least 20°, and particularly preferably at least 30°. This means that the parts of the processing tools that are further above the surface of the substrate in the intended operating position are further away from each other processing tool. This protects plant parts that are further away from the substrate. It may be provided that a part of the processing tool, for example a feeder section, connects directly to at least one engagement section above the surface. In such a case, it is essential that this part converges at least partially towards the substrate.

[0034] The angle is an angle pointing away from the surface.

[0035] When converging, the advancing parts or sections may be inclined towards each other, converging smoothly and / or uniformly. It may also be provided that the elements have steps or similar abrupt or discontinuous profiles that cause the convergence.

[0036] It can be provided that at least one engagement section of at least one machining tool is connected to the drive via at least one feeder section, and that preferably the feeder section connects directly to the engagement section. The feeder section serves as the mechanical connection between the drive and the engagement section, and thus for the movement of the latter. Further components, such as gears, deflection devices, arms, or the like, can be arranged between the feeder section and the drive. If the feeder section connects directly to the engagement section, it can effectively serve as an extension of the engagement section, and the mechanical force of the engagement section can be directly transmitted via the feeder section.It is particularly advantageous if at least one section of the working section has a moldboard that moves soil from the subsoil out of the row of plants, at least when the moldboard is closed. A moldboard, in this context, refers to a body similar to that of a plow, which, by its shape, engages the subsoil and, through its movement along the main direction of movement, moves soil laterally outwards, preferably away from the row of plants. Preferably, moldboards have an inclined or curved outer wall along the main direction of movement, allowing the subsoil to be pushed aside laterally. Such a moldboard can improve the removal of vegetation and, in particular, effectively move vegetation outwards during movement into the open position. In this sense, a moldboard is a component that fulfills such a function, similar to that of a plow (where it is also called a furrower or rudder).The material of the molding plate can be chosen freely; for example, it can be metal, wood, plastic, and / or fiberglass-reinforced material. The molding plate can have a helical or cylindrical shape.

[0037] It may also be provided that at least one processing tool has a flail that moves soil from the subsoil out of the row of plants, at least in the closed position.

[0038] Furthermore, it is advantageous if the engagement sections, in the closed position, form a common double scraper plate that moves soil from the subsoil out of the plant row in both directions, at least in the closed position. In other words, the engagement sections are designed to move soil from the subsoil out of the plant row in both directions, at least in the closed position. For this purpose, the engagement sections can have oppositely shaped scrapers, each pushing soil in a different direction perpendicular to the main direction of movement. By joining together in the closed position, they form a common double scraper plate. This allows for particularly thorough removal of vegetation from the plant row, as both sides can be covered.

[0039] Furthermore, it can be provided that at least one engagement section is plate-shaped. Plate-shaped in this context means a flat form. The engagement section preferably has a thickness that is significantly less than its width or height, particularly preferably at most one-fifth.

[0040] The plate shape allows for efficient removal of resistance to movement along the main direction of travel. Furthermore, this shape allows the substrate to be guided through the engagement section in specific directions. Preferably, at least one engagement section in the closed position is oriented essentially parallel to a main direction of travel of the transverse processing device, or at least one engagement section along the main direction of travel faces the other processing tool. This enables particularly effective removal of vegetation during transverse movement from the closed to the open position, but results in low resistance during movement along the main direction of travel in the closed position. Parallel alignment keeps resistance especially low.By aligning the machine with the main direction of movement, the sections of the working area located further forward along this direction are positioned closer together than those located further back. This forces the soil away from the row of plants, effectively removing the vegetation. The machine not only pushes vegetation out of the row when the planting area is closed, but also improves its further removal as the machine moves into the open position. This results in particularly efficient vegetation management.

[0041] It can be provided that at least a first subsection of the engagement section, in the closed position, is at a different angle to the main direction of movement than a second subsection of the engagement section, with the first subsection preferably being arranged in the closed position along the main direction of movement in front of the second subsection. Preferably, the angle of the first subsection to the main direction of movement is greater than the angle of the second subsection to the main direction of movement. This allows for better drainage of soil and vegetation from the row of plants.

[0042] The angle between the first and second sections of the engagement segment can be adjusted. This can be achieved, for example, by a hinge such as a micro-hinge or by a connection made of a suitable, sufficiently flexible material, such as aluminum. This allows the angle to be adapted to specific conditions such as ground conditions or the intended driving speed. Alternatively, the material in the area of ​​the connection can be made thinner or have recesses, thus simplifying angle adjustment.

[0043] Furthermore, it is preferably provided that each processing tool has a recirculating section for rotating the substrate, which is designed to be positioned below the surface of the substrate. The recirculating section improves the processing of the vegetation by processing and cutting or tearing away stems, roots, and other parts of the vegetation located in the substrate.

[0044] Preferably, the recirculating section is arranged adjacent to the engaging section, and particularly preferably, the engaging section borders the recirculating section. This arrangement can be direct, meaning the engaging section can be arranged directly on the recirculating section without any intervening parts. Alternatively, this arrangement can be indirect, meaning at least one intermediate element, such as a connecting section, can be arranged between the engaging section and the recirculating section.

[0045] Preferably, the recirculating section of at least one machining tool extends away from the engagement section of the other machining tool, preferably in the transverse direction and / or transverse to the main direction of movement. It may be provided that at least one recirculating section, in the closed position, is at an angle to the transverse direction.

[0046] Preferably, at least one engagement section of at least one machining tool is connected to the drive via at least one feeder section, and the feeder section is connected to the engagement section via the recirculation section. This allows for indirect support of the engagement section via the part of the machining tool that extends below the surface and results in a more flexible design of the area above the surface between the machining tools.

[0047] It is possible that at least one leading edge of at least one aerator section is inclined outwards in the transverse direction. This means that the portion of the leading edge closer to the engagement section is positioned further forward along the main direction of movement than a portion of the leading edge further away from the engagement section. This allows the vegetation to be pushed out of the plant row in the closed position and also improves the pushing out during movement into the open position.

[0048] Furthermore, it can be provided that at least part of the recirculation section of at least one machining tool is substantially perpendicular to the engagement section. This allows the recirculation section to extend substantially horizontally, while the engagement section extends vertically to overcome the surface of the substrate.

[0049] It can also be provided that at least a first section of the recirculation section, when closed, is positioned at a different angle to a plane formed by the main direction of movement and the transverse direction than a second section of the recirculation section. Preferably, the first section, when closed, is positioned upstream of the second section along the main direction of movement. Preferably, the angle of the first section of the recirculation section to the plane is greater than the angle of the second section of the recirculation section to the plane along the main direction of movement. This means that the second section is steeper than the first. This facilitates the mixing of the subsoil and the blending of the soil. This improves the processing of vegetation.

[0050] The angle between the first and second sections of the recirculation section can be adjusted. This can be achieved, for example, by a hinge such as a micro-hinge or by a connection made of a suitable, sufficiently flexible material, such as aluminum. This allows the angle to be adapted to specific conditions such as ground conditions or the intended driving speed. Alternatively, the material in the connection area can be made thinner or have recesses, thus simplifying angle adjustment.

[0051] Furthermore, it is advantageous if the transverse processing device has at least one sensor device for acquiring information regarding the crop plants and / or vegetation, and if the transverse processing device has a control device configured to control the drive based on the information acquired by the sensor device. The sensor device can comprise at least one optical sensor, preferably a camera or camera system. The control system can be designed such that the processing tools are held in a closed position during movement along the main direction of travel and are moved to an open position shortly before reaching a crop plant and to a closed position shortly after passing the crop plant. This allows the vegetation in the row of plants to be processed efficiently without damaging the crop plants.

[0052] The invention will subsequently be explained with reference to a non-limiting embodiment shown in the figures. These show:

[0060] Fig. 9 shows the embodiment of the machining tool from Fig. 8 in a side view;

[0061] Fig. 10 shows a second embodiment of a transverse machining device according to the invention in a rear view in a closed position;

[0062] Fig. 11 shows a third embodiment of a transverse machining device according to the invention in a rear view in a closed position.

[0063] The first embodiment of an agricultural transverse tillage device shown in the invention has one tillage unit designed for a single row of plants 1. In alternative embodiments, a transverse tillage device can also have several tillage units, each at least partially designed for different rows of plants 1. The tillage units can be arranged one behind the other or side by side along the main direction of movement H.

[0064] The machining unit shown has two machining tools 2, which are mounted on carriers 3. The machining tools 2 are pivotally mounted on parallel shafts 4, which can be rotated by a common drive 9. The pivot axes of the shafts 4 are perpendicular to the main direction of movement H and also perpendicular to the transverse direction Q, i.e., parallel to a vertical axis A. Thus, the machining tools 2 can be pivoted in a circular segment-shaped rotational movement between a closed and an open position.

[0065] The transverse processing device has two wheels in front of the processing tools, which are arranged offset from plant row 1. The transverse processing device can have a drive for movement along the main direction of movement H and / or be connectable to a towing vehicle, for example a tractor.

[0066] Each machining tool 2 has a feeder section 5, which is essentially horizontally oriented and extends towards the other machining tool 2. A gripping section 6, which is essentially vertically oriented, is arranged on each feeder section 5. By vertical, we mean that the gripping sections extend along a vertical axis A.

[0067] Each engagement section 6 is flat and / or plate-shaped. In the closed position, they face each other along the main direction of movement, as can be seen particularly in Figures 1 and 3. This means that they approach each other in the direction of the main direction of movement.

[0068] Due to their plate-like, inclined position along the main direction of movement H, the entire engagement section 6 each constitutes a strike plate that moves soil and vegetation laterally out of the row of plants. When assembled in the closed position, they together form a double strike plate that can move soil and vegetation out of the row of plants in a wedge or arrow shape on both sides.

[0069] The leading edges 6a of the engagement sections 6 are in close proximity in the closed position, separated only by a gap S. This gap S is preferably less than 1 cm wide. Alternatively, the leading edges 6a can also be in contact with each other.

[0070] The engagement sections 6 are in the closed position within the area of ​​the plant row 1, at close proximity to it. When deflected into the open position, they each move across an entire side in a transverse direction, clearing it of vegetation. In alternative embodiments, at least one engagement section 6 can be located in the closed position on the opposite side of the plant row 1, thus further increasing its effective area. This can be particularly advantageous when only one processing tool is present. At the end of each engagement section 6 facing the substrate, recirculation sections 7 are arranged. In this embodiment, these recirculation sections 7 are also plate-shaped, but they can also have other shapes. They extend perpendicular to the engagement sections 6 and essentially in the plane of the main direction of movement H and the transverse direction Q.Furthermore, they extend away from the row of plants essentially in the transverse direction Q, at an angle w to this direction. Both the trailing edges and the leading edges 7a of the turning sections 7 exhibit this angle. Thus, the leading edges 7a are inclined outwards in the transverse direction, pointing away from the row of plants and the main direction of movement H. During movement along the main direction of movement H in the closed position, vegetation from the row of plants is carried outwards in the transverse direction.

[0071] In the open position, the engagement sections 6 are spaced apart from each other. The distance between them is significantly greater than in the closed position, which allows the processing tools 2 to be moved past a crop in the row without damaging it.

[0072] The cross-processing device further comprises a sensor device 8, which is designed as a camera. It is connected to a control device 10, which acquires and evaluates the recorded data and uses this data to identify the positions of crops and / or vegetation. If a crop is located in the closed position immediately in front of the processing tools 2, the tools are moved to the open position and, after the crop has passed, are moved back to the closed position.

[0073] In Fig. 5 it is clearly visible that the recirculating sections 7 are largely angled so that, in the closed position, they are at an angle to the transverse direction Q. After a bending section connecting recirculating section 7 and engagement section 6, each recirculating section 7 is thus inclined outwards in the transverse direction Q. Both the leading edges 7a and the trailing edges 7b are at an angle of approximately 10° to 15° to the transverse direction Q in the closed position.

[0074] Figures 6 and 7 disclose an alternative embodiment of a processing tool, which could also be used in the embodiment according to the preceding figures. This processing tool differs from those shown in the preceding figures in that the engagement section 6 has a second sub-section 6d, to which a first sub-section 6c adjoins in the main direction of movement. The second sub-section 6d is at a smaller angle 10c than the first sub-section 6c (angle 10c) to the main direction of movement H, resulting in a greater outward displacement of the substrate and vegetation from the row of plants. The two sub-sections 6c and 6d together form a molding plate.

[0075] Figures 8 and 9 disclose an alternative embodiment of a machining tool, which could also be used in the embodiment according to Figures 1 to 5. This machining tool differs from those shown in the preceding Figures 1 to 5 in that the rotating section 7 has a second subsection 7d, to which a first subsection 7c adjoins in the main direction of movement. The second subsection 7d is arranged behind the first subsection 7c along the main direction of movement H. The first subsection lies parallel to a plane formed by the main direction of movement H and the transverse direction Q, i.e., at an angle of 180°, while the second subsection 7d is at an angle 11d of approximately 160°. This causes the substrate above the rotating section 7 to be guided upwards through its second subsection 7d and thus more thoroughly agitated.

[0076] The second embodiment shown in Fig. 10 is very similar to the first embodiment; therefore, only the most significant differences will be discussed here. Equivalent elements have the same reference numeral.

[0077] In this embodiment, the engagement sections 6 are extended away from the surface, lying directly next to each other in the closed position shown, in the area of ​​the substrate's surface – more precisely, their edges lie directly next to each other. They converge towards the substrate by being inclined towards each other. They form an angle θ, which in this embodiment is approximately 18°, but this angle can also be chosen differently.

[0078] This results in the ends of the engagement sections 6 facing away from the surface being further apart than the other ends.

[0079] The third embodiment shown in Fig. 11 is very similar to the first and second embodiments; therefore, only the most significant differences will be discussed here. Equivalent elements have the same reference numeral.

[0080] The third embodiment, like the second embodiment, has engagement sections 6 that converge towards the substrate in the closed position; however, they are significantly shorter and end only a few centimeters above the surface. The feeder sections 5 are arranged at the far ends of the circulation sections 7, leaving the central area between the circulation sections 7 above the surface essentially unobstructed.
