Description

[0001] The present invention relates to a row unit of an agricultural soil tillage implement, in particular an agricultural hoe, comprising a support frame, wherein the support frame has a receiving device and a fastening device, according to the preamble of the present patent claim 1. The present invention also relates to a method for adjusting the position of a tool-holding element of the row unit of the agricultural soil tillage implement. Furthermore, the invention relates to an agricultural soil tillage implement.

[0002] Soil tillage equipment with row units is known from the state of the art. Tools of different designs can be arranged on the respective row units, and these can also be interchanged and their position changed.

[0003] For this purpose, a plug-in system for the tools is known, by means of which a support frame, on which the tool can be mounted, can be inserted into an opening and can then be replaced or adapted to changing cultivation conditions on the agricultural land. The plug-in system is designed such that the tool can be inserted into the opening from the side, which is difficult and time-consuming to accomplish in confined spaces and with several row units arranged side by side.

[0004] Other tillage implements are known which cannot be adjusted with regard to the position of the tools.

[0005] The object of the present invention is therefore to provide a row unit of a soil tillage implement by means of which a particularly simple and time-saving fastening and adjustment of the tools is possible.

[0006] The underlying problem is solved by a row unit of an agricultural soil tillage device having the features of patent claim 1 and by a method having the features of patent claim 15 and an agricultural soil tillage device having the features of patent claim 17.

[0007] A core idea of ​​the present invention is to provide a row unit of an agricultural soil cultivation device, in particular an agricultural hoeing device, with a support frame, wherein the support frame has a receiving device and a fastening device. According to the invention, the receiving device is designed to receive the support frame or a tool-holding element according to the tongue and groove principle, and the fastening device is designed to secure the connection of the support frame to the tool-holding element.

[0008] For example, the row unit can be understood as meaning that a portion of an agricultural area can be cultivated along a line, preferably within a defined width or manner. For example, if the soil cultivation device is a hoe according to one embodiment, the row unit is used to cultivate the area between two rows of plants or seed rows, for example.

[0009] The term "agricultural tillage implement" refers, in particular, to an agricultural hoe. In particular, the tillage implement is suitable for mechanically removing weeds from the areas between two seed rows or for mechanically controlling weeds.

[0010] In principle, other soil cultivation equipment, preferably for mechanical weed control, such as a harrow or the like, can also be understood as such.

[0011] Preferably, the row unit can also be referred to as a soil tillage unit.

[0012] Preferably, the tool-holding element is designed such that a tool can be mounted on the tool-holding element. Particularly preferably, the tool can be removably mounted on the tool-holding element, thereby enabling replacement of a damaged tool.

[0013] Particularly preferably, the soil tillage implement can comprise a plurality of row units, in particular two or more. Each of the row units comprises a support frame on which at least one tool-holding element and, accordingly, tools can be arranged.

[0014] By way of example and not exclusively, the tool can be understood as, for example, a share, such as in particular a duckfoot share and / or a disc share, a hoeing element, etc. The tool can preferably be connected to the support frame via a tine, e.g., a spring tine, by means of the tool-holding element. The tine can expediently be mounted by means of a bearing point and / or be designed to be elastically deformable.

[0015] The respective row unit can further comprise a coupling device, in particular designed as a parallelogram linkage, for pivotably coupling the row unit to a, in particular transverse, carrier of the agricultural soil tillage implement, which can be pulled in particular by a towing vehicle, such as, for example, a tractor, a tractor and the like.

[0016] The row unit can have at least one actuator by means of which the support frame and preferably the at least one tool can be influenced, e.g., vertically moved, preferably via the coupling device, the support structure, and / or the tine. This can apply with respect to, and preferably with respect to, its location, position, and / or vibration behavior, preferably in order to ensure a substantially constant working state (e.g., working force (in particular preload force) and / or working depth) and / or a vibration-reduced, in particular substantially vibration-free, working position for the at least one tool.

[0017] The at least one actuator can be designed, for example, as a single-acting or double-acting working cylinder. The at least one actuator can alternatively or cumulatively be a linear drive or a rotary drive. The at least one actuator can alternatively or cumulatively be designed as an electric, pneumatic, or hydraulic actuator, in particular as an electric cylinder, pneumatic cylinder, or hydraulic cylinder.

[0018] It can also be provided that a depth control roller, also referred to as a depth control wheel or the like, is mounted on the respective soil cultivation device, which is preferably adjustable in height so that the height or working depth of the soil cultivation device can be adjusted. The depth control roller is preferably arranged on the support frame, preferably fixedly connected thereto and / or adjustable in its height.

[0019] According to the invention, it should be provided that the receiving device for receiving the tool-holding element or the support frame is designed according to the tongue and groove principle. The tongue and groove principle can be understood in such a way that one component corresponds to a groove and another component to a tongue. This means, for example, that the tool-holding element can be designed as a tongue and the support frame as a groove, or the tool-carrying element can be designed as a groove and the support frame as a tongue. The tongue can be at least partially introduced into the groove. In other words, the groove is designed in such a way that the groove can at least partially accommodate the tongue. The receiving device can be understood to be synonymous with the groove, whereby the groove can preferably be provided by the support frame or by the tool-holding element.

[0020] Furthermore, the invention provides a receiving device that is configured to receive the support frame or the tool-holding element according to the tongue-and-groove principle. Particularly preferably, the receiving device can be understood such that the support frame or the tool-holding element can constitute a receptacle and can at least partially receive the other element, specifically such that the connection between the support frame and the tool-holding element is configured according to the tongue-and-groove principle. Particularly preferably, the receiving device can encompass and / or have the groove.

[0021] The groove and the tongue are therefore designed in such a way that the groove and the tongue connect or can be connected to each other.

[0022] According to a particularly preferred embodiment, it can be provided that the receiving device can have the groove, wherein the groove is preferably formed by at least one recess, wherein the groove is preferably assigned to the support frame and / or formed by the support frame, wherein the tongue is substantially designed to be at least partially complementary to the groove, preferably to the at least one recess, preferably with regard to shape, wherein the tongue is preferably assigned to the tool-holding element and / or formed by the tool-holding element.

[0023] Particularly preferably, the receiving device has a receptacle, wherein the receptacle can preferably be formed by the at least one recess.

[0024] At least partially complementary is to be understood in such a way that small deviations and / or tolerances regarding dimensions may exist. Small deviations may even be considered preferable in order to ensure a good connection between the tongue and groove, given the relatively large dimensions of the components.

[0025] Due to the, at least partially, complementary design of the groove and the tongue, in particular with regard to the shape, the groove and the tongue can be easily and as closely as possible connected to each other.

[0026] Preferably, the groove can be assigned to the support frame and / or formed thereby. This can mean, for example, that the support frame is designed such that the support frame forms or has a groove. This can be achieved, for example, by the specific structural shape and / or by removing and / or adding material. Alternatively or additionally, further components could also be provided that define a groove and are assigned to the support frame, i.e., for example, mounted on it.

[0027] Preferably, the spring can be assigned to the tool-holding element and / or formed thereby. This can mean, for example, that the tool-holding element is the spring or has a corresponding spring.

[0028] According to a further preferred embodiment, it can be provided that the groove, which is preferably formed by the support frame, and the tongue, which is preferably formed by the tool-holding element, are configured in such a way that the tongue can be inserted into the groove without the application of force, preferably with a substantially precise fit. "Precise fit" can mean a positive fit. In particular, "positive fit" is to be understood in such a way that at least one movement of the tongue toward the groove can be prevented, at least substantially with respect to the direction of travel.

[0029] This makes it particularly easy for a user to mount the tool on the support frame without significant effort. Due to the preferred, essentially precise design, movement of the spring relative to the groove during operation, for example, when working on an agricultural area, can be suppressed or even eliminated, thus preventing damage to the components, such as deflection of the groove, bending of the spring, or the like.

[0030] According to a further preferred embodiment, the receiving device, in particular the receptacle of the receiving device, can be designed to be open at the top. Particularly preferably, the receptacle can be designed to be substantially U-shaped.

[0031] According to a further preferred embodiment, the recess can be an upwardly open recess, in particular a substantially U-shaped recess. The recess is preferably suitable for accommodating the spring, preferably the tool-holding element, at least in sections.

[0032] Because the recess is designed to be open at the top, it is possible for the tongue to be easily inserted, for example, into the groove. The insertion or insertion can be carried out conveniently and easily from above thanks to the upwardly open recess.

[0033] Particularly preferably, the recess is U-shaped. For the upwardly open design, the left and right legs are preferably arranged to extend vertically. A base leg connecting the left and right legs is preferably designed such that a transition from the left or right leg to the base leg is rounded, thereby reducing stresses that would otherwise occur, for example, due to a corner.

[0034] Further preferably, the base leg can be designed to be at least partially straight. This makes it possible to prevent rotation of the tongue relative to the groove, which could impede the operation and use of the tool, since the tool could rotate away from its intended position, for example, rotate backward during operation.

[0035] Particularly preferably, the groove and the tongue are designed in such a way that rotations of the groove and the tongue relative to each other can be prevented.

[0036] According to a further preferred embodiment, it can be provided that a minimum height of material is provided below the recess.

[0037] Purely by way of example, in the case where the groove, i.e., the recess, is formed in the support frame, it is preferably provided that the support frame is designed such that a minimum height of material is provided on the support frame, preferably below the groove, more preferably below the recess. The minimum height is preferably 2 cm, more preferably at least 3 cm, and further preferably at least 5 cm. Further preferably, it can be alternatively or cumulatively provided that a minimum section modulus, preferably of the support frame, is provided, preferably below the groove, more preferably below the recess, preferably in the vertical direction, so that rotation about the width direction is provided. The minimum section modulus can ensure safe and damage-free use of the soil cultivation equipment. Particularly preferably, the minimum section modulus is at least 1000 mm. 3 , preferably at least 1500 mm3 , more preferably at least 2000 mm 3 and particularly preferably at least 3000 mm 3 . The values ​​for the various grooves may vary. Alternatively or cumulatively, it may be provided that an effective area of ​​at least 400 mm 2 , preferably at least 450 mm 2 and particularly preferably at least 500 mm 2 is intended.

[0038] The same applies analogously to the case where the recess or groove is assigned to the tool-holding element.

[0039] It is conceivable that the minimum height for the support frame and the tool-holding element may differ.

[0040] According to a further preferred embodiment, the support frame may comprise a first longitudinal member and, more preferably, a second longitudinal member. Preferably, the groove, or more preferably the recess, may be formed by a first recess in the first longitudinal member and / or by a second recess in the second longitudinal member.

[0041] A longitudinal member is to be understood in such a way that a main extension direction extends in the longitudinal direction, which can be parallel to the direction of travel.

[0042] Preferably, the longitudinal members are arranged at a distance from one another, preferably in a direction transverse to the direction of travel.

[0043] Such a design can provide a stable support frame.

[0044] According to a further preferred embodiment, it can be provided that the support frame has a cross member connecting the first longitudinal member and the second longitudinal member.

[0045] According to a preferred embodiment, the cross member can be provided with the first longitudinal member and the second longitudinal member, each of which has at least partially a tenon joint and / or a further connection based on the tongue and groove principle. This allows the longitudinal members and the cross member to be pre-positioned during assembly, which, for example, makes welding the members together easier.

[0046] The cross member, which connects the longitudinal members to each other, can further increase the stability of the supporting frame. Preferably, the cross member is arranged such that the longitudinal members are spaced apart from each other by the cross member.

[0047] Particularly preferably, the support frame can be formed as a single piece or in one piece by the longitudinal members and the cross member. The support frame is preferably made from a single, uniform part (e.g., a tubular profile). It is also conceivable for the members to be welded together.

[0048] According to a further preferred embodiment, it can be provided that the groove and the tongue are designed such that the tongue is displaceable relative to the groove in order to displace the tool-holding element and, if appropriate, the tool relative to the support frame.

[0049] A displacement of the tongue relative to the groove, for example, a displacement of the tool-holding element relative to the support frame, means that the position of the tool-holding element and, if applicable, the tool changes relative to the row unit. This makes it possible to adjust the row unit or soil tillage device accordingly to the requirements of the agricultural area. For example, it may be necessary to work different (row) crops that were sown or planted at different intervals or row spacings.

[0050] Particularly preferably, the groove and tongue can be designed such that the tool-holding element or the tool can be displaced transversely (e.g., perpendicularly) to a direction of travel. The direction of travel is the direction of movement of the vehicle, which normally moves toward, along, or parallel to the rows of the crop.

[0051] The relocation is particularly easy to carry out according to the inventive concept of the connection according to the tongue and groove principle.

[0052] According to a further preferred embodiment, at least one position marker, preferably a plurality of position markers, can be provided on the spring. The one or more position markers can be used, for example, to indicate that a maximum displacement position has been reached. It is also possible for the one or more position markers to be designed in such a way that the distances between several tools of a soil cultivation device and between the tools and the support frame can be easily adjusted.

[0053] By way of example only and not exhaustively, the position markings can be printed, etched, lasered, formed by a material cutout, or similar. Designs that can ensure permanent readability and visibility are particularly advantageous.

[0054] According to a further preferred embodiment, two or more grooves and / or tongues can be provided. This is particularly advantageous with regard to the support frame, so that it is fundamentally possible for several tools to be mounted on the support frame, either as a groove or as a tongue. This also makes it possible to attach different or identical tools to the support frame.

[0055] According to a further preferred embodiment, the grooves and / or tongues can be either the same size or have different sizes. Preferably, the sizes of the grooves of the support frame and the sizes of the tongues of the support frame are compared with each other.

[0056] By providing different sizes of grooves or tongues, it may be possible, for example, that the respective tools can only be arranged in a certain position relative to or with respect to the support frame or row unit.

[0057] Alternatively or cumulatively, it may be provided that the grooves and / or tongues are each the same or different in shape.

[0058] By providing different shapes of the grooves or tongues, it may be possible, for example, that the respective tool-holding elements and accordingly the tools can only be arranged in a certain position relative to or with respect to the support frame or the row unit.

[0059] According to the invention, the row unit comprises a fastening device, wherein the fastening device is configured to secure the connection between the support frame and the tool-holding element. The fastening of the connection prevents the support frame and the tool-holding element from accidentally detaching from each other, for example, when using the row unit to cultivate the agricultural area.

[0060] According to the invention, it can be provided that the row unit comprises a fastening device which is preferably suitable for releasably and / or tool-free fastening or firmly connecting the spring, preferably the tool-carrying element, to the groove, preferably formed by the support frame or associated therewith.

[0061] By fastening or additionally fastening the tongue and groove to each other, unwanted and unintentional loosening of the tongue and groove can be prevented.

[0062] This is particularly advantageous when the tongue, for example, the tool-holding element, is inserted into the groove corresponding to the support frame, in the upwardly open recess. During operation, the tongue-and-groove connection could become loose if increased or repeated forces act on the tillage device or row unit along the vertical direction.

[0063] As described, it is advantageous if the attachment is detachable, so that the tools can still be changed or replaced. Furthermore, the possibility of relocating or shifting the tools is provided.

[0064] Alternatively or cumulatively, the embodiment provides for the attachment to be carried out without tools. This means that a user can establish or release the attachment simply by operating the fastening device.

[0065] Particularly preferably, the fastening device can be designed as a clamping unit and / or has a clamping unit that is preferably suitable for clamping the tool-holding element and the support frame. This means, for example, that the tool-holding element and the support frame are clamped against each other. Clamping the tool-holding element and the support frame provides a particularly simple and stable way of securing the parts to each other.

[0066] Particularly preferably, the clamping unit comprises a clamping element and a clamping mechanism. Preferably, the clamping element is adapted to be in contact with, or capable of being brought into contact with, the support frame and the tool-holding element.

[0067] Further preferably, the clamping mechanism is adapted to transmit a force to the clamping element when actuated for fastening, so that the tool-holding element is clamped to the support frame. On the other hand, if the clamping mechanism is actuated to release the fastening, the force acting on the clamping element is no longer sufficient to clamp the support frame and the tool-holding element.

[0068] Further preferably, according to the embodiment, it can be provided that the clamping mechanism is a toggle lever element.

[0069] According to a further preferred embodiment, the fastening device can be connected to the support frame or arranged or mounted thereon. Further preferably, the fastening device is assigned to the cross member or connected to it or mounted thereon.

[0070] This is particularly advantageous if the groove is formed by recesses in the longitudinal members, whereby the fastening device is arranged between the longitudinal members and can create a symmetrical fastening. This means that the force applied by the fastening device and introduced into the connection can be applied as symmetrically and evenly as possible.

[0071] According to a further preferred embodiment, it can be provided that the cross member and the longitudinal members are designed or arranged relative to one another in such a way that the spring, preferably the tool-holding element, rests at least partially on the cross member in the groove, preferably represented by the support frame.

[0072] It can further preferably be provided that the cross member has one or more through-openings. These can preferably be designed in such a way that the stability of the cross member and the entire support frame is not compromised. It can further preferably be provided that the through-openings are located in the area of ​​the tongue-and-groove joint, thereby preventing the accumulation of material, such as soil or the like, in the tongue-and-groove joint.

[0073] Alternatively, according to a preferred embodiment, the cross member and the longitudinal members are configured or arranged relative to one another in such a way that the spring, preferably the tool-holding element, is spaced apart from the cross member in the groove, preferably represented by the support frame, in the vertical direction. This may mean that the spring is only in contact with the longitudinal members.

[0074] The two designs allow for a good fastening of the tongue and groove to each other, especially when clamped.

[0075] The underlying problem is also solved by a method for adjusting a position of a tool-holding element, preferably a tool, which is preferably mounted or can be mounted on the tool-holding element, relative to a support frame of a series unit, characterized by the method steps: providing the support frame and the tool-holding element, wherein a tool is preferably assigned to the tool-holding element, and connecting the support frame and the tool-holding element according to the tongue and groove principle, wherein the tongue is preferably inserted into the groove, and fastening, in particular tool-free fastening, the support frame and the tool-holding element to one another.

[0076] According to a further preferred embodiment, it can be provided that the method comprises further method steps: preferably - loosening of the fastening of the tool-holding element relative to the support frame; - a displacement, preferably manual and / or mechanical displacement, of the tool-holding element relative to the support frame to the desired position; - fastening the support frame and the tool-holding element to each other, preferably by means of a fastening device.

[0077] The underlying problem is also solved by an agricultural soil tillage device with at least one row unit, preferably at least two row units, according to one embodiment.

[0078] Preferably, the agricultural soil cultivation device may be an agricultural hoeing device.

[0079] In particular, by providing an agricultural soil tillage implement with multiple row units according to one or more embodiments, it can be provided that the soil tillage implement can be adapted to different working conditions quickly and easily. This can include adapting the tools to a changed row or line spacing, replacing tool(s), adding or removing tools, changing the position of the tools, and / or the like. Defective tools can also be replaced quickly and easily without requiring disassembly of the row unit or neighboring row units.

[0080] For the purposes of the application, features disclosed in conjunction with other features may also be considered as disclosed in isolation.

[0081] All features disclosed for the row unit, the soil tillage implement and / or the method can be used in a corresponding manner with each other.

[0082] Further advantageous embodiments emerge from the subclaims.

[0083] Further objects, advantages, and benefits of the present invention will become apparent from the following description taken in conjunction with the accompanying drawings, in which: Fig. 1 a soil tillage implement with row units in a perspective view; Fig. 2 the soil tillage implement in accordance with Fig. 1 in a plan view; Fig. 3A a row unit in a perspective view; Fig. 3B the series unit according to Fig. 3A in another perspective view; Fig. 4 a section of the row unit according to Fig. 3A in a view from below; Fig. 5 a series unit in a further representation; Fig. 6 the series unit according to Fig. 5 with fastening devices; Fig. 7 a row unit with various tools; Fig. 8 a row unit with various tools; Fig. 9 a row unit in a perspective view; Fig. 10 a row unit in a top view.

[0085] In the Fig. 1 shows schematically and by way of example an agricultural soil tillage implement 1 in a perspective view.

[0086] As can be seen, the soil tillage implement 1 has a support 20 on which soil tillage devices or row units 2 can be arranged or connected to it. One or more tools 4 are arranged on the row units 2 and are preferably connected thereto. The support 20 is preferably arranged extending in a width direction B, wherein the width direction B is transverse to a longitudinal direction L, which can correspond to a direction of travel F.

[0087] The soil tillage implement 1 also has a hitch 21 suitable for connecting the soil tillage implement 1 to a towing vehicle. In this case, the hitch 21 is depicted as a 3-point hitch, although a towed or 2-point hitch is also conceivable.

[0088] In the Fig. 2 is a plan view of the soil tillage machine 1 according to Fig. 1. Here, the respective soil cultivation devices or row units 2 are more clearly visible, and it can be seen that each of the soil cultivation devices or row units 2 is connected to the carrier 20 by means of a coupling device 22. Preferably, the coupling device 22 is suitable for allowing the row unit 2 to be moved relative to the carrier 20, in particular displaced along a height direction H.

[0089] The coupling device 22 can be designed as a parallelogram linkage that is pivotable with the support 20 and pivotable with the row unit 2. This allows the soil tillage device 2 to be deflected along the height direction H relative to the support 20.

[0090] The soil tillage device or row unit 2 preferably comprises at least one actuator 24 designed as a working cylinder, by means of which the tools 4, preferably via a support frame 3, the coupling device 22 and / or the tines 26 as part of the tool 4 can be influenced, wherein a certain damping and / or springing of the movement of the soil tillage device or row unit 2 can preferably be achieved by the actuator 24. The soil tillage device 2 also comprises a depth control roller or a support wheel 25 for supporting or adjusting a working depth of the row unit 2. The tool 4 can preferably be understood as comprising the tine 26. This means that the tine 26 is intended as a connection to the respective tool-holding element 5, wherein the tool-holding element 5 is provided as a connection to the support frame 3.Particularly preferably, at least one tool 4 can be mounted or mountable on the tool-holding element 5.

[0091] In the following described Fig. 3A to 10, the embodiment according to the invention is illustrated and shown in more detail.

[0092] According to the Fig. 3A, the design is explained with regard to the tongue and groove principle of the connection between the support frame 3 and the tool-holding element 5. According to the Fig. 3A, the groove 6 is assigned to the support frame 3 and the tongue 7 to the tool-holding element 5. A receiving device 53 is provided, by means of which the support frame 3 and the tool-holding element 5 can be connected to one another. Preferably, the receiving device 53 is designed to receive the support frame 3 or the tool-holding element 5, preferably according to the tongue and groove principle. Preferably, it can be provided that the receiving device 53 can enable one or more connections according to the tongue and groove principle, i.e. that one or more grooves 6 and tongues 7 can be provided in each case. A fastening device 10 can be provided for fastening the groove 6 and the tongue 7, i.e. the support frame 3 and the tool-holding element 5.

[0093] The support frame 3 can, on the one hand, be manufactured in such a way that the grooves 6 are formed accordingly, for example, by removing and / or adding material. Regardless of the method of manufacturing the support frame 3, elevations 28, 29 are shown on the left and right sides of the support frame 3, with the first elevations 28 being arranged on the left side and the second elevations 29 on the right side.

[0094] Preferably, the elevations 28, 29 may be subsequently welded to the support frame 3. This prevents the support frame 3 from being weakened by the previously required material removal.

[0095] Preferably, a first elevation 28 and a second elevation 29 are spaced apart from one another in the width direction B and are preferably arranged opposite one another.

[0096] To further stabilize the structure, a first elevation 28 and the associated second elevation 29 may be connected by means of a connecting element 30. For example, the connecting element 30 may be designed as an angled tube, a round tube, or the like.

[0097] To facilitate insertion, the elevations 28, 29 are chamfered and / or have a slope, preferably at an upper end, which can provide guidance, particularly during insertion, for a respective tool-holding element 5. Preferably, the first elevation 28 and the associated second elevation 29 are chamfered on the same side.

[0098] The receptacle is formed as a groove 6 between two first elevations 28 and the corresponding second elevations 29. A spring 7, in this case the tool-holding element 5, can be inserted, for example, into the respective groove 6.

[0099] Further preferably, it can be provided that the support frame 3 has a first longitudinal member 11 and a second longitudinal member 12. Preferably, the longitudinal members 11, 12 are spaced apart from one another in the width direction B. Preferably, the support frame 3 has a cross member 13 which is designed to connect the longitudinal members 11, 12 to one another. Particularly preferably, the cross member is designed such that in the region of the groove or grooves 6, the cross member 13 is formed over the entire surface or almost over the entire surface or is provided with through openings, whereby the stability can be further increased. Preferably, it can also be provided that the respective tool-holding element 5 rests at least partially on the cross member 13 when the tool-holding element 5 is introduced into the groove 6.

[0100] Preferably, it can be provided that one or more position markings 16 are arranged on the respective tool-holding element 5, by means of which an easy and precise adjustment of the position of the tool-holding element 5, in particular with respect to the support frame 3, is possible.

[0101] A depth control roller 25 or a support wheel 25 is also shown, wherein the height of the depth control roller 25 can be adjusted by means of a depth control adjustment 27.

[0102] The elevations 28, 29 can have different configurations. In particular, the first and / or last elevation 28, 29 in the longitudinal direction L can be designed differently from the elevations 28, 29 located therebetween, and can preferably also be part of additional structures or be formed by additional structures.

[0103] According to the Fig. 3B will now be discussed in more detail with regard to the further fastening by means of a fastening device 10, which is shown in the Fig. 3B is shown and described in detail.

[0104] Preferably, the fastening device 10 is designed as a clamping unit 17, wherein the fastening device 10 comprises a clamping element 18 and a clamping mechanism 19.

[0105] The clamping element 18 is designed and positionable such that the tool-holding element 5 is spanned by the clamping element 18 along the longitudinal direction L. The clamping element 18 is suitable for being brought into contact with the connecting element 30, wherein the connecting element 30 is preferably arranged such that the clamping element 18 and the connecting element 30 can engage with one another. It is preferably provided that the clamping element 18 has at least one hooking section 33. The hooking section 33 preferably has a first hooking part 34 and a second hooking part 35. These are formed on a central part 39, in particular a flat central part 39, extending upwards in the height direction H. The connecting element 30 and the hooking section 33 are preferably arranged in front of the tool-holding element 5 in the longitudinal direction L.

[0106] Further preferably, the clamping element can have at least one positioning section 36, which is preferably arranged behind the tool-holding element 5 in the longitudinal direction L. The positioning section 36 preferably comprises a first positioning part 37 and a second positioning part 38, which extend downward from the central part 39 in the vertical direction H. This means that, viewed in the longitudinal direction L, the positioning parts 37, 38 overlap with the tool-holding element 5.

[0107] Likewise, the positioning section 36 is preferably designed and / or configured such that it can be brought into contact with the tool-holding element 5. The positioning section 36 is preferably designed such that, upon application of a downward force, for example, by the clamping mechanism 19, the respective positioning parts 37, 38 press against the tool-holding element 5 and position it relative to the groove 6.

[0108] Further preferably, the clamping element 18 has a slot 32 in the region of the positioning section 36, which is open at least on one side. The slot 32 is intended to accommodate a threaded element 31 onto which the clamping mechanism 19 can be mounted, for example, screwed.

[0109] Particularly preferably, the clamping mechanism 19 is a toggle lever element 40 or an eccentric lever 40, by means of which force can be transmitted to the clamping element 18 by actuation and accordingly the tool-holding element 5 can be clamped relative to the support frame 3.

[0110] Such a fastening device 10 enables a detachable and tool-free fastening of the tool-holding element 5 to the support frame 3. Once the fastening is established, a displacement of the tool-holding element 5 relative to the support frame 3 is not possible. Once the fastening is released, the tool-holding element 5 can be displaced relative to the support frame 3, in particular displaced in the width direction B. In particular, it can be provided that the displacement of the tool-holding element 5 relative to the support frame 3 is guided by the groove 6.

[0111] Preferably, the threaded element 31 is detachably connected to the support frame 3, in this case the cross member 14. If the threaded element 31 were rigidly and non-detachably connected to the support frame 3, there would be no possibility of replacing the threaded element 31 in the event of damage.

[0112] The fastening of the threaded element 31 is carried out using the Fig. 4 explained. The Fig. 4 is a section of a perspective view from below.

[0113] The support frame 3, in particular the cross member 14, has a through-opening 46 through which the threaded element 31 extends in a top-down direction. A first screw nut element 44 is provided on the threaded element 31. The threaded element 31 with the first screw nut element 44 can be formed by a screw.

[0114] To prevent the threaded element 31 from falling out of the through-hole 46 on its own, for example, when the clamping mechanism 19 is unscrewed, a second screw-nut element 45 and an additional element 41 are provided. The second screw-nut element 45 and the first screw-nut element 44 are arranged such that, in the vertical direction H, the first screw-nut element 44 is arranged below and the second screw-nut element 45 is arranged above the additional element 41. The screw-nut elements 44, 45 are preferably counter-locked against one another.

[0115] In order for the additional element 41 to remain in its position and not to move unnecessarily, a first mounting opening 42 is provided in one of the longitudinal members 11, 12 and a second mounting opening 43 is provided in the cross member 14, into which the additional element 41 can be inserted.

[0116] According to the Fig. 5 shows an example of a soil tillage device 2 with several tools 4, wherein each tool 4 is inserted and / or introduced into a groove 6 by means of corresponding tool-holding elements 5.

[0117] Exceptions may be tools 4 that are positioned at the very front and / or the very back in the longitudinal direction L. Although a groove is visible on the foremost tool 4, this is formed from a recess, so that easier insertion is also possible here. This recess is also shown for the foremost tool in the Fig. 3B. Such a configuration may be preferred because the depth control adjustment 27 is arranged directly above the tool-holding element 5 of this tool 4. The rearmost tool 4 is optional and is mounted on a reinforcement frame 47 of the support frame 3, which is preferably located between the longitudinal beams 11, 12 and is non-removable as part of the support frame 3.

[0118] According to the Fig. 6, the fastening devices 10 are also provided, as described in Fig. 5. Preferably, each tongue and groove connection is assigned a fastening device 10.

[0119] In the Fig. 7 and Fig. 8 shows various tools 4, which can be arranged on a support frame 3 by means of tool-holding elements 5. It is also conceivable for multiple tools 4 to be arranged on a tool-holding element 5. The tools 4 are purely exemplary and not exhaustive or exclusive: a goosefoot 48, a row guard plate 49, and a half-side goosefoot 50, which can also function as a guard plate. Finger hoes, harrow elements, rotary harrows, or the like would also be conceivable.

[0120] In the Fig. 9 and Fig. 10 shows the support frame 3 in more detail, whereby the tool 4 and other elements have been omitted.

[0121] According to the Fig. 9 is a perspective view from above and in the Fig. 10 shows a top view.

[0122] It can be seen that the cross member 13 can have through-openings 51. Preferably, a through-opening 51 can be arranged in the cross member 13 such that the through-opening 51 is at least partially located in the region of the groove or grooves 6. This can mean that there can be only partial contact, rather than full-surface contact, between the cross member 13 and the groove 6. Preferably, the tool 4 can rest at least partially on a web element 52 of the cross member 13.

[0123] Further preferably, the through opening 46 and the first mounting opening 42 can be formed in the respective web element 52.

[0124] All features disclosed in the application documents are claimed as essential to the invention, provided that they are new, individually or in combination, compared to the prior art.
