Description

[0001] The invention relates to a soil cultivation machine, in particular for agricultural use.

[0002] Soil cultivation machines can be used to loosen arable soil. For this purpose, so-called tines with attached shares can be used. Traditionally, all tines of a soil loosening device are identical.

[0003] DE 92 10 389 U1 relates to a cultivator or soil cultivation implement with tines, concave disc levelers, and a roller. The cultivator is designed as a single-beam, multi-row short cultivator with three front and three rear tines. The front and rear tines are identical. The front tines are each rigidly connected to a frame support plate that projects forward from a frame crossbeam. The rear tines are each rigidly connected to a frame support plate that projects rearward from the frame crossbeam.

[0004] DE 10 2005 005 939 A1 discloses an agricultural implement with a frame on which tillage tools are arranged in several spaced-apart and successive transverse rows on crossbeams, spaced apart from each other and offset from each other. The crossbeams are cranked. The tillage tools are arranged at the apex of the crank.

[0005] DE 10 2021 108 227 A1 already discloses a soil cultivation machine that is improved in comparison.

[0006] The invention is based on the objective of creating a soil cultivation machine that is an alternative to, in particular, DE 10 2021 108 227 A1, preferably more compact and / or structurally simpler.

[0007] The problem is solved by the features of the independent claim. Advantageous further developments are specified in the dependent claims and the description.

[0008] The invention relates to an agricultural soil cultivation machine according to claim 1.

[0009] The soil cultivation machine comprises a frame, wherein the frame includes a first crossbeam and a second crossbeam, which may be connected to each other, for example, by at least one longitudinal beam.

[0010] The first crossbeam is advantageously positioned in front of the second crossbeam with respect to the direction of work. The first crossbeam can therefore be, for example, a front crossbeam, and the second crossbeam can be, for example, a rear crossbeam.

[0011] For example, the first crossbeam and the second crossbeam can be connected laterally on the outside via a longitudinal beam (preferably extending substantially parallel or obliquely to the working direction), whereby it is alternatively or additionally possible that, for example, a longitudinal beam connects the first crossbeam and the second crossbeam centrally.

[0012] The soil cultivation machine comprises a soil loosening device with several first tine assemblies and several second tine assemblies. The frame preferably forms the supporting frame of the soil loosening device.

[0013] According to the invention, several of the first tine devices and several of the second tine devices are attached to the first crossbeam, preferably pivotably.

[0014] The first tine devices and the second tine devices can (preferably in the longitudinal direction of the first cross member) be arranged alternately next to each other on the first cross member.

[0015] Several of the first tine devices and / or several of the second tine devices are attached to the second crossbeam, preferably pivotably.

[0016] The first tine devices and the second tine devices can (preferably in the longitudinal direction of the second cross member) be arranged alternately next to each other on the second cross member.

[0017] The first set of tines is advantageously longer than the second set of tines with respect to the working direction. Thus, the first set of tines can advantageously project further rearward on the first crossbeam and / or the second crossbeam than the second set of tines (advantageously with respect to the working direction).

[0018] The tillage machine, in particular the soil loosening device, has a maximum working width of 6m, 5m, 4m or 3m or less. Furthermore, the tillage machine has a 3-point hitch for attaching (e.g., coupling) to a towing vehicle (e.g., a tractor, etc.).

[0019] The soil cultivation machine can therefore preferably be designed as a three-point linkage machine.

[0020] The invention makes it possible in particular for the first crossbeam and the second crossbeam to form a (e.g. two-beam) soil loosening device with expediently two (preferably formed by the first crossbeam and the second crossbeam) rows of crossbeams, but with at least three or at least four (preferably formed by means of the first tine devices and the second tine devices) transverse rows of tines.

[0021] Thus, the soil loosening device and / or the frame can preferably comprise, for example, only the first crossbeam and the second crossbeam as a crossbeam structure for supporting the first tine devices and the second tine devices, but advantageously at least three or at least four tine cross rows.

[0022] Advantageously, the soil loosening device can therefore include more, e.g. at least twice as many, tine cross rows as crossbeams to support the first and second tine assemblies.

[0023] The soil loosening device can, for example, include the frame with the first crossbeam and the second crossbeam, and the first tine devices and the second tine devices.

[0024] It is possible that at least two rows of tines assigned to the second (and thus expediently rear) crossbeam are formed behind the second crossbeam in the working direction.

[0025] It is possible that the first tine devices and second tine devices attached to the first crossbeam are arranged in front of the second crossbeam in the working direction.

[0026] It is possible that, in the direction of work, the soil cultivation machine does not include another crossbeam with a tine device behind the second crossbeam.

[0027] It is possible that the soil loosening device and / or the frame, as crossbeam structures (in particular for supporting the first tine assemblies and the second tine assemblies), comprises only two crossbeams, namely in particular the first crossbeam and the second crossbeam, and / or only two rows of crossbeams, but preferably comprises at least three or at least four tine crossbeams, e.g. at least twice as many tine crossbeams as crossbeams.

[0028] The soil cultivation machine can be designed, for example, without a support wheel and / or without a chassis wheel, and thus in particular without a support wheel and / or without a chassis wheel to support the soil cultivation machine.

[0029] The soil loosening device can be designed, in particular, by means of the first tine devices and the second tine devices, to produce a (preferably essentially uniform) tine spacing of less than or equal to 30cm, 29cm, 28cm, 27cm, 26cm or 25cm.

[0030] The soil loosening device can, for example, create a row spacing (e.g. 30cm) by means of the first tine devices and the second tine devices, wherein the first tine devices and the second tine devices can be spaced apart from each other on the first cross member and / or on the second cross member by, for example, (preferably essentially) at least twice the row spacing (e.g. 60cm), at most three times and / or at most four times the row spacing.

[0031] It is possible that the first tine assemblies and the second tine assemblies are arranged symmetrically or asymmetrically on the first crossbeam (especially relative to the longitudinal axis of the tillage machine). Alternatively or additionally, the sum of the first tine assemblies and the second tine assemblies on the first crossbeam can be an odd or even number.

[0032] It is possible that the first and second tine assemblies are arranged symmetrically or asymmetrically on the second crossbeam (especially relative to the longitudinal axis of the tillage machine). Alternatively or additionally, the sum of the first and second tine assemblies on the second crossbeam can be an odd or even number.

[0033] It is possible that, for example, exactly three first tine assemblies and, for example, exactly three second tine assemblies are attached to the first crossbeam, with, preferably, exactly four first tine assemblies and, expediently, exactly three second tine assemblies being attached to the second crossbeam.

[0034] It is possible that, for example, exactly two first tine assemblies and, for example, exactly three second tine assemblies are attached to the first crossbeam, with preferably, for example, exactly three first tine assemblies and expediently exactly three second tine assemblies being attached to the second crossbeam.

[0035] The first crossbeam can extend, for example, from one (preferably outermost) side of the frame and / or the soil loosening device to the other (preferably outermost) side of the frame and / or the soil loosening device, preferably continuously (e.g., in a straight line), ideally in such a way that it can form a continuous support structure over its entire longitudinal extent. The first crossbeam can, for example, span the longitudinal axis of the soil cultivation machine.

[0036] The second crossbeam can extend, for example, from one (preferably outermost) side of the frame and / or the soil loosening device to the other (preferably outermost) side of the frame and / or the soil loosening device, preferably continuously (e.g., in a straight line), ideally in such a way that it can form a continuous support structure over its entire longitudinal extent. The second crossbeam can, for example, span the longitudinal axis of the soil cultivation machine.

[0037] The first crossbeam and the second crossbeam preferably extend parallel to each other.

[0038] The frame can, for example, form a frame closed in its circumferential direction, e.g., in order to be able to form a circumferentially closed supporting structure.

[0039] It is possible that the first crossbeam has a sum of first and second tine devices attached (e.g. 6 or 5) and the second crossbeam has a sum of first and second tine devices attached (e.g. 7 or 6), and the sum on the first crossbeam is smaller than the sum on the second crossbeam.

[0040] The first crossbeam can be positioned, for example, in front of the second crossbeam with respect to the direction of work.

[0041] The first crossbeam and the second crossbeam can be expediently spaced apart with respect to the working direction, the distance being greater than, for example, 500mm, 550mm, 600mm, 650mm, 700mm, 750mm or 800mm.

[0042] The soil cultivation machine, e.g. the soil loosening device, can have a maximum working width of, for example, less than or equal to 6m, 5m, 4m or 3m.

[0043] It is possible that several third tine assemblies, preferably pivotable, are mounted on the first crossbeam and / or the second crossbeam, and preferably the several third tine assemblies are longer in the working direction than the several first tine assemblies. It is also possible that several fourth tine assemblies, preferably pivotable, are mounted on the first crossbeam and / or the second crossbeam, and preferably the several fourth tine assemblies are longer in the working direction than the several third tine assemblies, etc.

[0044] The third, fourth and / or fifth, etc., tine assemblies may be expediently designed in the same way as the first tine assemblies, with the exception of their length.

[0045] The first tine devices and / or the second tine devices can be designed, for example, as disclosed in DE 10 2021 108 227 A1.

[0046] For example, the first tine assemblies may each have: a fastening area for attachment, particularly detachable attachment, to the first crossbeam and / or the second crossbeam, wherein the fastening area has a contact section for contact with the first crossbeam and / or the second crossbeam (e.g., direct contact with the first and / or second crossbeam or direct contact with a shear restraint of the frame); a tine shank, preferably hook-shaped and / or rod-shaped (e.g., polygonal rod, preferably square rod); and / or a share for engaging the soil, which is arranged at a soil-side end of the tine shank. For example, it is possible that...It is possible that the length of the first tine assembly, measured with respect to the working direction from a rearmost end of the contact section to a rearmost end of the tine shank, is greater than or (expediently essentially) equal to the height of the first tine assembly, measured with respect to a vertical axis of the first tine assembly from a bottommost end of the contact section to a bottommost end of the share.

[0047] Preferably, the term "prong assembly" used herein refers to a prong assembly that may, for example, be designed to be detachable or removable from the frame without damage. On the other hand, the term "frame" preferably refers to the frame in the narrower sense (i.e., longitudinal beams and crossbeams) and additionally to elements that are, for example, integrally connected or formed as a single piece with the frame in the narrower sense, such as a welded-on sheet metal plate or a welded-on shear protection device.

[0048] Preferably, the fastening area can be designed to allow the tine assembly to be attached, preferably detachably, to a support, preferably a crossbeam, of the frame of the soil cultivation machine.

[0049] Preferably, the mounting area and the tine shank can be designed separately from each other or as separately provided components. Alternatively, the mounting area and the tine shank can be integrally formed or connected as a single piece.

[0050] For example, the tine shank and the share can be integrally formed as a single piece. Alternatively, the share can be detachably attached to the tine shank, e.g., by means of a screw connection.

[0051] In one embodiment, the length is less than or equal to twice the height.

[0052] In another embodiment, the length is greater than or substantially equal to 700 mm, 800 mm, 900 mm, or 1000 mm. Alternatively or additionally, the length can be less than 1300 mm, 1200 mm, or 1100 mm. Alternatively or additionally, the height can be greater than or substantially equal to 600 mm, 700 mm, 800 mm, or 850 mm. Alternatively or additionally, the height can be less than 1100 mm, 1000 mm, or 900 mm.

[0053] In another embodiment, the overall length of the first tine assembly, in the working direction, is greater than or substantially equal to the overall height of the first tine assembly. Alternatively or additionally, the overall length of the tine shank, in the working direction, can be greater than or substantially equal to the overall height of the tine shank.

[0054] In another embodiment, the tine stem is pivotably connected to the mounting area (e.g. by means of a pivot axis, a swivel bolt or a pivot pin).

[0055] In a further embodiment, the tine shank is at least two-part, with a preferably essentially straight shank section, which is preferably pivotably connected to the mounting area (e.g., by means of a pivot axis, a swivel bolt, or a pivot pin), and a hook-shaped shank section, which preferably has the bottom end. This allows, for example, a comparatively long tine shank and thus a comparatively long first tine assembly to be achieved in a structurally simple manner. Likewise, this enables a component-sharing strategy, whereby the hook-shaped shank section can be used both in the suitably long first tine assembly and in a suitably short second tine assembly.

[0056] For example, the essentially straight handle part and the hook-shaped handle part can be attached directly to each other and / or to each other by means of the at least one swivel arm and / or by means of the at least one stiffening element.

[0057] In one embodiment, the first tine assembly has a pre-tensioning device (e.g., separate from the tine shank) that elastically pre-tensions the tine shank in one direction relative to the ground. Preferably, a front end of the share can be positioned behind a rear end of the pre-tensioning device with respect to the working direction, or at substantially the same position or height as a rear end of the pre-tensioning device with respect to the working direction. Alternatively or additionally, the length of the first tine assembly can be at least 25%, at least 50%, or at least 100% greater than the total length of the pre-tensioning device with respect to the working direction.

[0058] Preferably, the total length of the tine shank can be at least 25%, at least 50% or at least 100% greater than the total length of the pretensioning device with respect to the working direction.

[0059] Preferably, the preloading device can be arranged above the tine shank. For example, the preloading device can comprise a fluid cylinder or a spring, preferably a coil spring. For example, the preloading device can be pivotably mounted at the mounting point (e.g., by means of a pivot bolt or a pivot pin). Optionally, the preloading device can be pivotably connected to the tine shank (e.g., by means of a pivot bolt or a pivot pin and / or at least one pivot arm and / or by means of a joint).

[0060] A longitudinal axis of the prestressing device can, for example, be aligned horizontally, vertically, or at an angle to the horizontal and vertical.

[0061] In a further embodiment, the first tine assembly also comprises at least one pivot arm, which is pivotably connected to the mounting area and / or pivotably to the pretensioning device, and is attached to the tine shank, wherein the tine shank is preferably clamped between two pivot arms. The pivot arm can preferably stabilize the assembly and enable a longer service life.

[0062] For example, at least one swivel arm can be a cast part or a forged part.

[0063] It is possible that no swivel arm is included. The tine shank can be pivotally connected to the mounting area, e.g., with a pivot pin or a swivel bolt.

[0064] It is also possible that the first tine assembly further comprises at least one stiffening element, preferably a stiffening plate, wherein the at least one stiffening element stiffens the tine shank (and, for example, the at least one pivot arm), preferably in a section of the tine shank adjacent to the mounting area and, for example, below the pre-tensioning device. The stiffening element can preferably stabilize the assembly and enable a longer service life.

[0065] In one embodiment, the length of the first tine assembly is adjustable with respect to the working direction, preferably by means of a perforated plate connection (e.g., between the at least one swivel arm and the tine shank). This allows the first tine assembly to be adapted for different applications and arrangements, e.g., as a short, advantageously second tine assembly or as a long, advantageously first tine assembly.

[0066] It is possible that the prestressing device is selected from a group of different and / or differently long prestressing devices, depending on the length.

[0067] In a further embodiment, the mounting area is designed to detachably attach the first prong assembly to a shear restraint of the frame, in particular to the first cross member and / or second cross member. Alternatively, the mounting area can be designed, for example, as a bracket, preferably a multi-part one, which is designed for clamping and / or screwing (e.g., on all four sides) to the frame, in particular to the first cross member and / or second cross member.

[0068] It goes without saying that the first prong devices can each be appropriately designed as previously discussed.

[0069] As already mentioned, the first tine assemblies are expediently longer in terms of the working direction than the second tine assemblies, e.g. by at least 20%, 30%, 50%, 80% or 100%.

[0070] For example, the second tine assembly can each be designed as follows. Preferably, the second tine assembly can have a mounting area for detachably attaching the second tine assembly to the frame (e.g., the first cross member and / or the second cross member), wherein the mounting area has a contact section for contacting the frame (e.g., the first cross member and / or the second cross member) (e.g., direct contact with the first cross member and / or the second cross member or direct contact with a shear restraint of the frame (e.g., the first cross member and / or the second cross member)). The second tine assembly can, for example, have a tine shank, preferably hook-shaped and / or rod-shaped (e.g., a polygonal rod, preferably a square rod). The second tine assembly can preferably have a share for engaging the soil, which is arranged at a soil-side end of the tine shank.Preferably, the length of the second tine assembly, measured with respect to the working direction from a rearmost end of the contact section of the mounting area of ​​the second tine assembly to a rearmost end of the tine shank of the second tine assembly, can be greater, lesser or substantially equal to the height of the second tine assembly, measured with respect to a vertical axis of the second tine assembly from a lowermost end of the contact section of the mounting area of ​​the second tine assembly to a lowermost end of the share of the second tine assembly.

[0071] The longer design of the first tine assemblies compared to the second tine assemblies can be achieved, for example, through various design measures that can be combined with one another.

[0072] In one embodiment, the multiple first tine assemblies and the multiple second tine assemblies each have a tine shank, wherein the multiple tine shanks of the multiple first tine assemblies can each be longer with respect to the working direction than the multiple tine shanks of the multiple second tine assemblies, preferably by at least 20%, 30%, 50%, 80% or 100%.

[0073] In one embodiment, the multiple first tine assemblies and the multiple second tine assemblies each have at least one pivot arm, and the multiple pivot arms of the multiple first tine assemblies are each longer with respect to the working direction than the multiple pivot arms of the second tine assemblies, preferably by at least 20%, 30%, 50%, 80% or 100%.

[0074] In one embodiment, the multiple first tine assemblies and the multiple second tine assemblies each have a mounting area (e.g. designed as a holder) which is preferably detachably (e.g. removable) attached to the frame, in particular the first and / or second cross member, and the multiple mounting areas of the multiple first tine assemblies are each longer with respect to the working direction than the multiple mounting areas of the second tine assemblies, preferably by at least 20%, 30%, 50%, 80% or 100%.

[0075] The first set of tines on the second crossbeam can be the last set of tines of the soil loosening device and / or the soil cultivation machine with respect to the working direction of the soil cultivation machine.

[0076] The first tine assemblies can be arranged in at least two consecutive transverse rows of tines. Alternatively or additionally, the second tine assemblies can be arranged in at least two consecutive transverse rows of tines. In one embodiment, the multiple second tine assemblies and the multiple first tine assemblies have at least one identical component, preferably a (preferably hook-shaped) stem part of the respective tine stem, a share, a mounting area designed as a holder for detachably attaching the respective tine assembly to the frame, in particular to the first and / or second cross member, a pretensioning device, and / or a hinge (e.g., for the pretensioning device).

[0077] The first crossbeam can be, for example, the foremost crossbeam of the frame and / or the soil loosening device.

[0078] The second crossbeam can be, for example, the rearmost crossbeam of the frame and / or the soil loosening device.

[0079] The second crossbeam can, for example, form a rear crossbeam of the frame and / or the soil loosening device, while alternatively or additionally, the first crossbeam can, for example, form a front crossbeam of the frame and / or the soil loosening device.

[0080] It is possible that the multiple first tine assemblies and / or the multiple second tine assemblies are arranged behind the first and / or second crossbeam with respect to a working direction of the tillage machine.

[0081] In another embodiment, the multiple first tine assemblies and the multiple second tine assemblies are the only tine assemblies of the soil loosening device and / or the tillage machine. Alternatively or additionally, the soil loosening device can be the only soil loosening device of the tillage machine.

[0082] It is also possible that the soil loosening device has additional tools for loosening the soil, e.g. discs and / or knife rollers, etc., whereby the additional tools may be positioned upstream or downstream of the first and / or second tine devices with respect to the direction of work.

[0083] In one embodiment, the soil cultivation machine further comprises a soil leveling device for leveling the soil loosened by the soil loosening device, wherein the soil leveling device may be arranged, in particular, behind the soil loosening device with respect to the direction of work.

[0084] In another embodiment, the multiple first tine assemblies are arranged closer to the soil leveling device than the multiple second tine assemblies, opposite to the working direction. This advantageously achieves a particularly favorable soil flow during loosening, resulting in improved leveling than would be possible, for example, with larger distances between the tine assemblies and the soil leveling device.

[0085] In one embodiment, the distance between the multiple first tine assemblies and the ground leveling device with respect to the working direction is less than or substantially equal to 2000 mm, 1500 mm, 1000 mm, 500 mm, 400 mm or 350 mm.

[0086] For example, the soil leveling device may have several rotatable discs (e.g. concave discs), several levelers, several harrows and / or other tine devices arranged and designed for leveling the soil.

[0087] In one embodiment, the soil cultivation machine further comprises a (e.g., single) soil reconsolidation device, preferably comprising a packer roller, for reconsolidating the soil leveled by the soil leveling device. The soil reconsolidation device can be arranged, for example, behind the soil leveling device with respect to the working direction.

[0088] It is possible that the working depth of the first and second tine units can be adjusted by adjusting the height of the soil reconsolidation device.

[0089] The soil leveling device and / or the soil reconsolidation device may, in particular, have a maximum working width of, for example, less than or equal to 6m, 5m, 4m or 3m.

[0090] It should be noted that the first crossbeam and / or the second crossbeam, or expediently more generally the soil loosening device, may have a plurality of first tine arrangements and / or second tine arrangements as disclosed herein.

[0091] In a preferred embodiment, the soil loosening device has at least four transverse rows of tines, but advantageously only two suitably assigned crossbeams, namely the first crossbeam and the second crossbeam. The at least four transverse rows of tines can, for example, each have both first tine assemblies and second tine assemblies.

[0092] The preferred embodiments and features of the invention described above can be combined in any way desired. Further details and advantages of the invention are described below with reference to the accompanying drawings. These show: Figure 1 is a perspective view of a soil cultivation machine according to an embodiment of the present disclosure; Figure 2 is a front view of the exemplary soil cultivation machine of Figure 1Figure 3 shows one side of the exemplary soil cultivation machine from Figure 1; Figure 4 shows the other side of the exemplary soil cultivation machine from Figure 1.

[0093] The embodiments shown in the figures are at least partially identical, so that similar or identical parts are provided with the same reference numerals and, to avoid repetition, reference is also made to the description of the other embodiments or figures for their explanation.

[0094] The Figures 1 to 7 Figures 1 and 2 show different views of an agricultural tillage machine 10 for cultivating agricultural land (arable soil). The tillage machine 10 is preferably a trailed tillage machine. For example, the tillage machine 10 can be pulled by a towing vehicle, such as a tractor. The tillage machine 10 can be moved across the arable land in a working direction A1. The working direction A1 runs, in particular, parallel to a longitudinal axis L1 of the tillage machine 10 and, for example, perpendicular to a vertical axis H1 of the tillage machine 10.

[0095] The soil cultivation machine 10 has a frame 18, wherein the frame 18 comprises a first crossbeam 32A and a second crossbeam 32B and optionally at least one longitudinal beam. The frame 18 forms a frame closed in its circumferential direction, wherein the first crossbeam 32A is arranged in front of the second crossbeam 32B with respect to the working direction A1.

[0096] The soil cultivation machine 10 has a soil loosening device 12 comprising several first tine assemblies 24 and several second tine assemblies 22, the frame 18 preferably forming the support frame of the soil loosening device 12. The first and second tine assemblies 24, 22 have a working direction A2 which expediently corresponds to the working direction A1 of the soil cultivation machine 10.

[0097] The soil cultivation machine 10 may also optionally have a soil leveling device 14 and / or a soil recompaction device or soil reconsolidation device 16.

[0098] The soil loosening device 12 is designed to loosen the arable soil. The soil loosening device 12 can be arranged, preferably directly in front of the soil leveling device 14 with respect to the working direction A1.

[0099] Several first tine assemblies 24 and several second tine assemblies 22 are attached to the first crossbeam 32A, preferably pivotably (e.g., detachably or permanently). The first tine assemblies 24 and the second tine assemblies 22 are arranged (advantageously in the longitudinal direction of the first crossbeam 32A), e.g., alternately side by side on the first crossbeam 32A.

[0100] Several first tine assemblies 24 and several second tine assemblies 22 are also attached to the second crossbeam 32B, preferably pivotably (e.g., detachably or permanently). The first tine assemblies 24 and the second tine assemblies 24 are arranged (advantageously in the longitudinal direction of the second crossbeam 32B), e.g., alternately side by side on the second crossbeam 32B.

[0101] The first tine assemblies 24 are expediently longer with respect to the working direction A1 than the several second tine assemblies 22, so that preferably on both the first cross member 32A and the second cross member 32B the first tine assemblies 24 (expediently with respect to the working direction A1) extend further to the rear than the second tine assemblies 22.

[0102] The first crossbeam 32A and the second crossbeam 32B together with the first tine devices 24 and the second tine devices 22 preferably form a, for example, two-beam soil loosening device 12 with two rows of crossbeams formed by means of the first crossbeam 32A and the second crossbeam 32B and, in particular, four transverse rows of tines formed by means of the first tine devices 24 and the second tine devices 22.

[0103] The soil cultivation machine 10 can in particular include a 3-point hitch 30 for attachment to a towing vehicle, wherein the 3-point hitch 30 can be expediently attached, for example, to the frame 18 and / or the first cross member 32A. Alternatively or additionally, the soil cultivation machine 10, preferably the soil loosening device 12, can have a maximum working width of less than or equal to 6 m, 5 m, 4 m or 3 m.

[0104] The soil loosening device 12 is designed by means of the first tine devices 24 and by means of the second tine devices 22 such that it produces a tine spacing S of less than or equal to 30cm, 29cm, 28cm, 27cm, 26cm or 25cm (e.g. Figure 2 ).

[0105] The soil loosening device 12 can, for example, generate a tine spacing S (e.g. 28cm) by means of the first tine devices 24 and the second tine devices 22, wherein the first tine devices 24 and the second tine devices 22 can be spaced apart from each other on the first crossbeam 32A and on the second crossbeam 32B by, for example, substantially twice the tine spacing S (e.g. 56cm) or even more than twice the tine spacing S.

[0106] The first crossbeam 32A extends continuously and expediently in a straight line from one outer side of the frame 18 and / or the soil loosening device 12 to the other outer side of the frame 18 and / or the soil loosening device 12, preferably in such a way that it can form a continuous support structure over its entire longitudinal extent. The first crossbeam 32A can, for example, span a longitudinal axis L1 of the soil cultivation machine 10.

[0107] The second crossbeam 32B also extends continuously and expediently in a straight line from one outer side of the frame 18 and / or the soil loosening device 12 to the other outer side of the frame 18 and / or the soil loosening device 12, preferably in such a way that it can form a continuous support structure over its entire longitudinal extent. The second crossbeam 32B can, for example, span the longitudinal axis L1 of the soil cultivation machine 10.

[0108] On the first crossbeam 32A, a sum of first and second tine devices 24, 22 is attached, namely six, and on the second crossbeam 32B, a sum of first and second tine devices 24, 22 is attached, namely seven, so that the sum on the first crossbeam 32A is smaller than the sum on the second crossbeam 32B.

[0109] The Figures 1 to 7 Figure 3 shows an embodiment in which exactly three first tine assemblies 24 and exactly three second tine assemblies 22 are attached to the first crossbeam 32A, and exactly four first tine assemblies 24 and exactly three second tine assemblies 22 are attached to the second crossbeam 32B. The first tine assemblies 24 and the second tine assemblies 22 are arranged asymmetrically on the first crossbeam 32A, whereas the first tine assemblies 24 and the second tine assemblies 22 are arranged symmetrically on the second crossbeam 32B.

[0110] Preferably, the soil loosening device 12 can be designed for non-inversion tillage, loosening and crumbling the soil, and / or for weed control and incorporating crop residues into the soil. The soil loosening device 12 can preferably be designed with four rows and thus preferably have four transverse rows of tines.

[0111] It is possible that the soil loosening device 12 has several further soil loosening tools, such as discs and / or knife rollers, etc. The several further soil loosening tools can be positioned upstream or downstream of the second tine assemblies 22 and / or the first tine assemblies 24 with respect to the working direction A1, for example.

[0112] An exemplary embodiment for the first tine devices 24 is described with reference to the Figures 15 to 18An exemplary embodiment for the second tine devices 22 is described with reference to the Figures 19 and 20 described.

[0113] The multiple tine assemblies 22, 24 are designed for loosening the soil. For this purpose, the tine assemblies 22, 24 can furrow the soil. The penetration depth of the tine assemblies 22, 24 into the soil can vary depending on the specific application and can be adjusted, for example, by means of the soil reconsolidation device 16.

[0114] The multiple tine devices 22, 24 are preferably designed or usable to penetrate the soil to a maximum working depth of 250 mm to 350 mm.

[0115] The preload of the first tine assembly 24 and the preload of the second tine assembly 22 can be different. The tine assemblies 22 and 24 can each have pivotally mounted tine shanks.

[0116] The first tine assemblies 24 can be arranged closer to the ground leveling device 14 than the second tine assemblies 22, opposite to the working direction A1 or with respect to the longitudinal axis L1. Preferably, the distance with respect to the longitudinal axis L1 between the first tine assemblies 24 and the ground leveling device 14 can be less than or substantially equal to 2000 mm, 1000 mm, 500 mm, 400 mm or 350 mm.

[0117] The first tine assemblies 24 are longer with respect to the longitudinal axis L1 than the second tine assemblies 22. Preferably, the first tine assemblies 24 are at least 20%, 30%, 50%, 80% or 100% longer than the second tine assemblies 22.

[0118] For example, the tine shanks of the first tine assemblies 24 can be longer with respect to the longitudinal axis L1 than the tine shanks of the second tine assemblies 22. Preferably, the tine shanks of the first tine assemblies 24 can be at least 20%, 30%, 50%, 80%, or 100% longer than the tine shanks of the second tine assemblies 22.

[0119] However, it is also possible that additionally or alternatively, other elements of the first tine assembly 24 are longer with respect to the longitudinal axis L1 than corresponding elements of the second tine assembly 22. For example, a bracket or a fastening area for detachably attaching (e.g., clamping) the first tine assembly 24 to the frame 18 can be longer with respect to the longitudinal axis L1 or the working direction A1 than a bracket or a fastening area for detachably attaching (e.g., clamping) the second tine assembly 22 to the frame 18, e.g., by at least 20%, 30%, 50%, 80%, or 100%. For example, a swivel arm for pivotally mounting a tine shank of the first tine assembly 24 with respect to the longitudinal axis L1 or the working direction A1 can be longer than a swivel arm for pivotally mounting a tine shank of the second tine assembly 22. B. by at least 20%, 30%, 50%, 80% or 100%.

[0120] For example, the tine devices 22, 24 can be arranged spaced apart from each other in several tine rows (in particular tine transverse rows) along the longitudinal axis L1, preferably in four tine rows.

[0121] Preferably the first tine devices 24 and / or the second tine devices 22 are arranged apart from each other with respect to a transverse axis Q1 of the soil cultivation machine 10.

[0122] In a preferred embodiment (see e.g. Figures 1 to 7 and Figures 8 to 14 ) the soil loosening device 12 has four transverse rows of tines, but only two suitably assigned crossbeams, namely the first crossbeam 32A and the second crossbeam 32B, wherein the four transverse rows of tines each have both first tine devices 24 and second tine devices 22.

[0123] The soil loosening device 12 can, for example, be supported on the frame 18. As already mentioned, the tine assemblies 22, 24 are preferably attached to the crossbeams 32A and 32B of the frame 18, for example, detachably. Preferably, the tine assemblies 22, 24 are clamped to the crossbeams 32A and 32B of the frame 18 in a positive-locking and force-locking manner. The crossbeams 32A and 32B can, for example, be designed as tubes or beams and / or have a square profile. The crossbeams 32A and 32B can, for example, be connected to each other via several longitudinal beams of the frame 18.

[0124] The soil leveling device 14 can be configured to level the soil loosened by the soil loosening device 12. The soil leveling device 14 is arranged downstream of the soil loosening device 12 with respect to the working direction A1. The soil leveling device 14 can also be arranged upstream of the soil reconsolidation device 16 with respect to the working direction A1.

[0125] The soil leveling device 14 can be designed in different ways. For example, the soil leveling device 14 can have a plurality of leveling elements. Preferably, the leveling elements can have rotatable (for example, hollow) discs 26. The discs 26 can each have an axis of rotation that is inclined to the longitudinal axis L1 and inclined to the transverse axis Q1. The rotating discs 26 can be arranged side by side in a row with respect to the transverse axis Q1. The rotating discs 26 can be arranged in a transverse row perpendicular to the longitudinal axis L1 or the working direction A1. The rotating discs 26 can level the trenches or furrows produced by the soil loosening device 12.

[0126] Alternatively or additionally to the discs 26, the soil leveling device 14 can, for example, include harrows, several additional tine assemblies, and / or levelers as leveling elements. The additional tine assemblies would accordingly be designed and arranged, in contrast to the tine assemblies 22 and 24, to level the already loosened soil. For example, the additional tine assemblies may penetrate the soil less deeply than the tine assemblies 22 and 24. Alternatively or additionally, the additional tine assemblies may, for example, carry different shares than the tine assemblies 22 and 24, with these different shares being designed for leveling.

[0127] The soil leveling device 14 can be supported on the frame 18. For example, the discs 26, the harrows or the other tine devices can be attached to one or more crossbeams of the frame 18.

[0128] The soil reconsolidation device 16 can be configured to reconsolidate the soil loosened by the soil loosening device 12 and leveled by the soil leveling device 14. The soil reconsolidation device 16 can be arranged behind the soil loosening device 12 and behind the soil leveling device 14 with respect to the working direction A1. For example, the soil reconsolidation device 16 can have one or more (identical or different) rotatable packer rollers 28. The packer roller 28 can be configured in different ways depending on the application. The soil reconsolidation device 16 or the packer roller 28 can be supported on the frame 18, preferably on the second cross member 32B of the frame 18, preferably in a height-adjustable manner.

[0129] The frame 18 is preferably formed from several longitudinal beams and crossbeams 32A, 32B. The longitudinal beams and / or the crossbeams 32A, 32B can have any profile or cross-sectional shape, e.g., round or polygonal. Preferably, the longitudinal beams and / or the crossbeams are designed as square tubes or square beams.

[0130] The frame 18 can support the soil loosening device 12 and, if applicable, the soil leveling device 14 and / or the soil reconsolidation device 16.

[0131] The frame 18 or, more generally, the soil cultivation machine 10 preferably does not include a support wheel and preferably also no chassis wheel for supporting the soil cultivation machine 10.

[0132] In a working position, the soil cultivation machine 10 can preferably be supported exclusively by means of, for example, the soil reconsolidation device 16 and the 3-point linkage device 30.

[0133] Preferably, the working depth of the tine devices 22, 24 can be adjusted by adjusting the height of the soil reconsolidation device 16.

[0134] The Figures 8 to 14 show different views of an agricultural soil cultivation machine 10 according to another embodiment of the invention.

[0135] A special feature of the soil cultivation machine 10 is, for example, that exactly two first tine devices 24 and exactly three second tine devices 22 are attached to the first crossbeam 32A, while exactly three first tine devices 24 and exactly three second tine devices 22 are attached to the second crossbeam 32B.

[0136] On the first crossbeam 32A, the first tine devices 24 and the second tine devices 22 are arranged symmetrically, while on the second crossbeam 32B, the first tine devices 24 and the second tine devices 22 are arranged asymmetrically.

[0137] On the first crossbeam 32A, a sum of first and second tine assemblies 24, 22 is attached, and on the second crossbeam 32B, a sum of first and second tine assemblies 24, 22 is attached, wherein the sum on the first crossbeam 32A is preferably smaller than the sum on the second crossbeam 32B. In the exemplary embodiment of the Figures 1 to 7 The sum at the first crossbeam 32A is, for example, six, and at the second crossbeam 32B, for example, seven, whereby in the exemplary embodiment the Figures 8 to 14 The sum at the first crossbeam 32A is, for example, five, and at the second crossbeam 32B is, for example, six.

[0138] Both in the exemplary embodiment of the Figures 1 to 7as well as in the exemplary embodiment of the Figures 8 to 14 The first crossbeam 32A and the second crossbeam 32B, together with the first tine assemblies 24 and the second tine assemblies 22, form a two-beam, in particular two-crossbeam, soil loosening device 12 with preferably exactly four transverse rows of tines. The soil loosening device 12 and / or the frame 18 preferably comprises only the first crossbeam 32A and the second crossbeam 32B as a crossbeam structure for supporting the first tine assemblies 24 and the second tine assemblies 22, but advantageously at least four transverse rows of tines.

[0139] The Figures 15 to 18 Figures 24 show different views of a preferred embodiment for the first tine assembly 24, in particular for the first tine assemblies 24, each advantageously designed according to the Figures 15 to 18 can be trained.

[0140] The first tine assembly 24 can loosen the soil in a working direction A2 corresponding to the working direction A1 of the tillage machine 10. The first tine assembly 24 can have a longitudinal axis L2 that is parallel to the longitudinal axis L1 of the tillage machine 10. The first tine assembly 24 can have a vertical axis H2 that is parallel to the vertical axis H1 of the tillage machine 10.

[0141] The first tine assembly 24 has a mounting area 36, ​​a tine shank 38, a pretensioning device 40, and a share 42. The first tine assembly 24 may optionally also have at least one pivot arm 44 and / or at least one stiffening element 46.

[0142] The mounting area 36 is preferably designed as a bracket, as shown. The bracket is designed to attach the first tine assembly 24 to the frame 18 of the soil cultivation machine 10, and in particular to the first crossbeam 32A or the second crossbeam 32Ban (e.g., by clamping, preferably by positive and non-positive locking).

[0143] For example, the bracket can have two bracket bodies 48, 50. The bracket bodies 48, 50 can form a receptacle, preferably a through-hole, between them for a support of the frame 18. The receptacle can, for example, have a polygonal cross-section or profile, e.g., rectangular as shown. The receptacle can, for example, be formed by two opposing, recessed sections of the bracket bodies 48, 50. To attach the first prong assembly 24 to the frame 18 (in particular to the first cross member 32A or the second cross member 32B), a support of the frame 18 can be received in the receptacle and the bracket bodies 48, 50 can be fastened to one another, e.g., by means of several screw connections. The support can be clamped in the receptacle by the bracket bodies 48, 50 in a force-fit and form-fit manner.

[0144] Alternatively, the fastening area 36 can, for example, be designed to be detachably attached to a so-called shear restraint of the frame 18 (in particular of the first cross member 32A or the second cross member 32B) (not shown in the figures). For example, such a fastening area can be plate-shaped and have at least one through-hole. For instance, such a fastening area can be integrally formed in one piece with the prong shank 38.

[0145] The mounting area 36 has a contact section or contact surface 51 which, when mounted on the frame 18 (in particular on the first cross member 32A or on the second cross member 32B), bears against the frame 18 (in particular on the first cross member 32A or on the second cross member 32B). The contact section 51 can be formed, for example, by inner surfaces of the bracket, preferably the bracket bodies 48, 50.

[0146] The tine shank 38 can preferably be pivotably mounted on the mounting area 36, ​​e.g. by means of a pivot bolt or pivot pin. A pivot axis can preferably be perpendicular to the vertical axis H2 and perpendicular to the working direction A2 or the longitudinal axis L2. Preferably, the tine shank 38 can be arranged behind the mounting area 36 with respect to the working direction A2.

[0147] The tine shank 38 supports the share 42 at a bottom end of the tine shank 38, preferably detachably. For example, the share 42 can be connected to the tine shank 38 by means of several screw connections. Alternatively, the share 42 can be formed integrally with the tine shank 38, for example.

[0148] The prong stem 38 is preferably rod-shaped. For example, the prong stem 38 can be designed as a polygonal rod, preferably a square rod.

[0149] The prong handle 38 can be one-piece or multi-piece. For example, the prong handle 38 can have a first handle part 52 and a second handle part 54.

[0150] The first handle section 52 can be positioned behind the second handle section 54 with respect to the working direction A2. The first handle section 52 can be hook-shaped. The first handle section 52 can have the bottom end of the tine handle 38. The share 42 can be attached to the first handle section 52. Alternatively, the share 42 can, for example, be formed integrally with the first handle section 52.

[0151] The second stem section 54 can be straight. The second stem section 54 can be connected directly and / or pivotally to the mounting area 36 by means of the pivot arms 44. The pivotable bearing can be parallel to a pivotable bearing of the pretensioning device 40 on the mounting area 36. The second stem section 54 can share a pivot bolt or pivot pin with at least one pivot arm 44 for pivotal mounting on the mounting area 36.

[0152] The handle sections 52, 54 can be attached directly to one another and / or to one another by means of the swivel arms 44, e.g., by means of screw connections. The handle sections 52, 54 can each have one or more holes, preferably through holes, for the screw connections. The holes can be spaced apart from one another with respect to the longitudinal axis L2 or the working direction A2. The handle sections 52, 54 can be designed as flat profiles.

[0153] It is also possible, for example, that the second stem part 54 is omitted or that the stem parts 52 and 54 are integrally formed as one piece.

[0154] The pre-tensioning device 40 is designed to elastically pre-tension the tine shank 38 and the share 42 against the ground. The pre-tensioning force can be predetermined or adjustable by a design feature of the pre-tensioning device 40. Preferably, the pre-tensioning device 40 can be a pressurized fluid cylinder, e.g., a hydraulic cylinder, as shown in the figures. Alternatively or additionally, the pre-tensioning device 40 can, for example, include a spring, preferably a coil spring.

[0155] The pre-tensioning device 40 can be arranged above the tine shank 38, preferably the second shank section 54. The pre-tensioning device 40 can be arranged behind the fastening area 36 with respect to the working direction A2.

[0156] The pre-tensioning device 40 is preferably pivotably connected to the mounting area 36, ​​e.g. by means of a pivot pin or a pivot bolt. The pivot axis is preferably perpendicular to the vertical axis H1, perpendicular to the working direction A2 or longitudinal axis L2 and / or parallel to the pivotable bearing of the pivot arms 44 and / or the tine shank 38 on the mounting area 36.

[0157] Preferably, the pre-tensioning device 40 is pivotably connected to the tine shank 38, e.g., directly or indirectly. The pivotable connection can be provided, for example, by means of a joint 56 and the pivot arms 44. The joint 56 can, for example, be pivotably connected to sections or projections of the pivot arms 44 that extend upwards along the vertical axis H2. The joint 56 can, for example, have a pivot pin and / or a ball joint section.

[0158] The pivotable connection of the pretensioning device 40 with the holder 38 can preferably be arranged in front of the pivotable connection of the pretensioning device 40 with the swivel arms 44 or the prong shank 38 with respect to the working direction A2.

[0159] The share 42 is designed to engage and loosen the soil. The share 42 can be detachably attached to the tine shank 38, for example, by means of screw connections, or it can be integrally formed as a single piece with the tine shank 38. Depending on the application, the design of the share 42 can vary, for example, depending on the desired penetration depth and the soil conditions. The share 42 may have additional parts beyond those shown, for example, parts on the left and right sides of the tine shank 38 in a front view of the tine shank 38 (not shown).

[0160] The pivot arms 44 are designed to pivotally connect the tine shank 38 to the mounting area 36, ​​e.g. by means of a pivot bolt or a pivot pin and / or parallel to a pivotable bearing of the pretensioning device 40 on the mounting area 36. The pivot arms 44 are preferably pivotally connected to the pretensioning device 40 by means of the joint 56.

[0161] The pivot arms 44 can extend parallel to the second stem section 54. The pivot arms 44 are preferably elongated. The pivot arms 44 can be designed as flat profiles.

[0162] The swivel arms 44 can be arranged directly below the pre-tensioning device 40. With respect to the working direction A1, the swivel arms 44 can be arranged behind the mounting area 36. The swivel arms 44 can rest against the tine shank 38.

[0163] The swivel arms 44 can have several holes, preferably through holes, for screw connections to the tine shank 38, preferably to the shank sections 52, 54. The holes can be spaced apart from each other with respect to the longitudinal axis L2 or the working direction A2. The tine shank 38 can be clamped between the swivel arms 44.

[0164] The depicted swivel arms 44 are provided in pairs. However, it is also possible that, for example, only one swivel arm 44 is included. Alternatively, for example, no swivel arm may be included and the tine shank 38 may only be pivotably mounted directly on the mounting area 36.

[0165] It is possible for the overall length of the tine shank 38 and / or the first tine assembly 24 to be adjustable with respect to the working direction A2 or the longitudinal axis L2. For example, a desired overall length can be achieved by selecting the aligned holes of the tine shank 38 and the swivel arms 44. This technique allows for discrete adjustment of the overall length and can be based on a perforated plate connection.

[0166] The stiffening elements 46 are designed to stiffen the pivot arms 44 and the tine shank 38. The stiffening elements 46 can abut the pivot arms 44. The stiffening elements 46 can be arranged directly below the pre-tensioning device 44. Preferably, the stiffening acts particularly in a section of the tine shank 38 and the pivot arms 44 directly below the pre-tensioning device 40 and adjacent to the mounting area 36.

[0167] The stiffening elements 46 are preferably designed as elongated stiffening plates. The stiffening elements 46 can be designed as flat profiles. The stiffening elements 46 can have several holes, preferably through holes, for the screw connections to the tine shank 38, preferably the shank sections 52, 54, and the swivel arms 44. The holes can be spaced apart from each other with respect to the longitudinal axis L2 or the working direction A2. The tine shank 38 and the swivel arms 44 can be clamped between the stiffening elements 46.

[0168] Preferably the holes in the stiffening elements 46, the swivel arms 44 and the prong handle 38 (the handle parts 52, 54) are aligned with each other.

[0169] The stiffening elements 46 shown are provided in pairs. However, it is also possible that, for example, only one stiffening element 46 is included. Alternatively, for example, no stiffening element may be included at all.

[0170] The first tine assembly 24 is comparatively long or longer than conventionally designed with respect to the longitudinal axis L2, in particular longer than the second tine assembly 22.

[0171] The comparatively large overall length of the first tine assembly 24 can be achieved by various measures that can be combined with one another, e.g. by extending the tine shank 38, extending the design of the at least one swivel arm 44 and / or extending the design of the fastening area 36 with respect to the working direction A2 or the longitudinal axis L2.

[0172] The large overall length of the first tine assembly 24 can be characterized by different geometric ratios of the first tine assembly 24, which can occur individually or in any combination with each other.

[0173] For example, the total length of the first tine assembly 24 with respect to the working direction A2 or the longitudinal axis L2 can be at least as large as the total height of the first tine assembly 24 with respect to the vertical axis H2.

[0174] For example, the overall length of the tine shank 38 with respect to the working direction A2 can be greater than or substantially equal to the overall height of the tine shank 38. For example, the share 42 and / or the bottom end of the tine shank 38 can be located behind the mounting area 36 and behind the pretensioning device 40 with respect to the working direction A2 or the longitudinal axis L2.

[0175] For example, the length I of the first tine assembly 24, with respect to the working direction A2, can be measured from a rearmost end of the contact section 51 to a rearmost end of the tine shank 38. The height h of the first tine assembly 24, with respect to a vertical axis H2 of the first tine assembly 24, can be measured from a lowest end of the contact section 51 to a lowest end of the share 42. The length I can be greater than or substantially equal to the height H (see Figure 11 Preferably, the length I can be less than or equal to twice the height h.

[0176] For example, the length I of the first tine assembly 24 can be greater than or substantially equal to 700 mm, 800 mm, 900 mm, or 1000 mm, and / or the length I of the first tine assembly 24 can be less than 1300 mm, 1200 mm, or 1100 mm. The height h of the first tine assembly 24 can be greater than or substantially equal to 600 mm, 700 mm, 800 mm, or 850 mm, and / or the height h of the first tine assembly 24 can be less than 1100 mm, 1000 mm, or 900 mm.

[0177] For example, the total length of the tine shank 38 can be at least 25%, at least 50%, preferably at least 100% greater than the total length of the pretensioning device 40 with respect to the working direction A2 or the longitudinal axis L2.

[0178] The Figures 19 and 20 Figures 22 show different views of a preferred embodiment for the second tine assembly 22, in particular for the second tine assemblies 22, each advantageously designed according to the Figures 19 and 20can be trained.

[0179] The second tine assembly 22 is designed similarly to the first tine assembly 24. However, the second tine assembly 22 is preferably significantly shorter than the first tine assembly 24 with respect to the longitudinal axis L2 or the working direction A2.

[0180] For example, the overall length of the second tine assembly 22 with respect to the working direction A2 or the longitudinal axis L2 can be less than the overall height of the second tine assembly 22 with respect to the vertical axis H2. For example, the overall length of the tine shank 38' with respect to the working direction A2 or the longitudinal axis L2 can be less than the overall height of the tine shank 38' with respect to the vertical axis. For example, the share 42 and / or the bottom end of the tine shank 38' with respect to the working direction or the longitudinal axis L2 can be located behind the mounting area 36 and / or directly below the pretensioning device 40.

[0181] Again Figure 20 As can be seen, a length I of the second tine assembly 22 measured with respect to the working direction A2 starting from a rearmost end of the contact section 51 to a rearmost end of the tine shank 38 can be less than a height h of the second tine assembly 22 measured with respect to a vertical axis H2 of the second tine assembly 22 starting from a bottommost end of the contact section 51 to a bottommost end of the share 42.

[0182] For example, the length I of the second tine assembly 22 can be greater than or substantially equal to 200 mm, 300 mm, 400 mm, or 500 mm, and / or the length I of the second tine assembly 22 can be less than 800 mm, 700 mm, or 600 mm. The height h of the second tine assembly 22 can be greater than or substantially equal to 600 mm, 700 mm, 800 mm, or 850 mm, and / or the height h of the second tine assembly 22 can be less than 1100 mm, 1000 mm, or 900 mm.

[0183] For example, the total length of the tine shank 38' can essentially correspond to the total length of the pretensioning device 40 with respect to the working direction A2 or the longitudinal axis L2, or be only slightly larger or even smaller.

[0184] For example, a comparison of the Figure 16 and 20 As a result, a tine shank 38' of the second tine assembly 22 can be shorter with respect to the longitudinal axis L2 or the working direction A2 than the tine shank 38 of the first tine assembly 24. For example, the tine shank 38' can be formed only by the shank part 52. The tine shank 38 can be formed by the shank parts 52 and 54. Preferably, the tine shank 38 of the first tine assembly 24 can be at least 20%, 30%, 50%, 80%, or 100% longer than the tine shank 38' of the second tine assembly 22.

[0185] For example, a comparison of the Figure 16 and 20This results in the at least one pivot arm 44' of the second tine assembly 22 being shorter with respect to the longitudinal axis L2 or the working direction A2 than the at least one pivot arm 44 of the first tine assembly 24. Preferably, the pivot arm 44 of the first tine assembly 24 can be at least 20%, 30%, 50%, 80% or 100% longer than the pivot arm 44' of the second tine assembly 22.

[0186] Although not explicitly shown in the figures, it is also possible that the mounting areas 36 of the tine assemblies 22, 24 can be of different lengths with respect to the working direction A2 or the longitudinal axis L2. Preferably, the mounting area 36 of the first tine assembly 24 can be at least 20%, 30%, 50%, 80% or 100% longer than the mounting area 36 of the second tine assembly 22 (not shown in the figures).

[0187] Preferably, the tine assemblies 22 and 24 share several identical parts. For example, the stem parts 52, the pretensioning devices 40, the mounting area 36 designed as a bracket, the bracket bodies 48, 50 and / or the joints 56 can be designed as identical parts.

[0188] It is understood that the soil cultivation machine 10, in particular the first and / or second crossbeam 32A, 32B, may preferably have a plurality of first zinc devices 24 as disclosed herein (e.g. Figures 15 to 18 ) and / or may have a plurality of second zinc devices 22 as disclosed herein (e.g. Figures 19 and 20 ).

[0189] In an embodiment not shown, several third tine assemblies, preferably pivotable, can be attached to the first crossbeam 32A and / or the second crossbeam 32B, wherein, for example, the several third tine assemblies can be longer with respect to the working direction A1 than the several first tine assemblies 24. Otherwise, the third tine assemblies can be designed, for example, like the first tine assemblies 24 disclosed herein. Reference symbol list
