Description

[0001] The invention relates to a carrier device for carrying a soil cultivation tool for an agricultural soil cultivation implement according to the preamble of claim 1, a pre-skimming device for an agricultural soil cultivation implement according to the preamble of claim 13, and a soil cultivation unit for an agricultural soil cultivation implement according to the preamble of claim 16.

[0002] Agricultural tillage equipment typically comprises tillage tools that, during the cultivation of agricultural land, work the soil by disturbing it. Agricultural plows are equipped for soil cultivation, in particular with plow bodies and skimmers. The skimmers break up the soil immediately in front of the plow bodies, remove the top layer of soil along with crop residues, and throw or deposit them to the side in the furrows drawn into the soil by the plow bodies.

[0003] Changing environmental conditions, such as varying vegetation cover, soil composition, or changes in the plow's working or driving speed, can affect the skimmers' operating parameters, particularly the throwing distance and angle of the removed soil and crop residues. This can lead to unintended changes in the operating parameters and a corresponding reduction in the plow's working quality. Therefore, it is necessary to be able to adjust the skimmers' throwing angle to adapt to changing environmental conditions, ensuring that the soil and crop residues removed by the skimmers are always delivered into the furrow with the intended throwing angle and distance.

[0004] It has already been recognized in the prior art that an adjustable throwing angle of the skimmers is practical. For example, German patent application DE 43 39 254 B4 discloses a skimmer adjustment mechanism which pivots all skimmers of a plow together by means of an adjusting device via a connecting rod linked to the skimmer brackets by means of lever arms.

[0005] From the publication EP 2 314 139 B1 it is also known to adjust the throwing angle of the skimmers of a plow by means of pluggable wedges in an adjusting device of the skimmers between the guide and the shank of the skimmers.

[0006] However, the throwing angle adjustments for skimmers known from the prior art have disadvantages and are in need of improvement in practice. An adjusting device that adjusts the skimmers via a connecting rod and several lever arms connected to the skimmer brackets involves considerable technical complexity due to the large number of moving components. This increases the susceptibility to errors and failures, particularly due to wear and contamination of the mechanical components of the adjusting device, such as joints, as well as manufacturing and maintenance costs. Even when adjusting the throwing angle using a wedge, additional adjusting elements are used to achieve the angle adjustment. These additional components drive up costs and increase the susceptibility to errors.When adjusting the angle using a wedge, it is essential to ensure that the wedge remains in its position during soil cultivation by means of an additional fixing, for example with clamps or bolts.

[0007] The object underlying the invention is therefore to implement an angle adjustment for a soil cultivation tool on a soil cultivation machine, which can be done without additional components, thus reducing the effort, the susceptibility to errors and the costs of the angle adjustment.

[0008] The problem is solved with a support device of the type mentioned above, wherein the first support body and the second support body have a first longitudinal rotation angle relationship to each other in the first assembly position and a second longitudinal rotation angle relationship to each other in the second assembly position.

[0009] By implementing the throwing angle adjustment via two different longitudinal rotation angle relationships in two different mounting positions of the first and second support bodies, additional components such as wedges or complex adjusting devices like connecting rods and lever arms can be omitted. This significantly simplifies the throwing angle adjustment mechanism, thereby simplifying the manufacturing of the components, the assembly of the throwing angle adjustment mechanism, and the assembly of the entire pre-skimmer assembly. Furthermore, the reduced number of components required for manufacturing and assembly lowers production and assembly costs. Maintenance work on the pre-skimmer assembly is also simplified.A lower complexity of the throwing angle adjustment also results in a lower susceptibility to errors in the throwing angle adjustment and ensures reliable operation without the throwing angle unintentionally changing during soil cultivation.

[0010] The support device is preferably designed as a pre-squeegee support. The support bodies are preferably elongated. The support bodies are preferably designed as square stems. The support bodies preferably have a substantially rectangular cross-section. The support bodies are preferably made of a metallic material, for example, steel or aluminum. The support bodies can also be made of a plastic. The support bodies are preferably mounted directly to one another without an intermediate piece, for example, without a wedge. The longitudinal rotation angles between the first and the second support body are preferably different in the first longitudinal rotation angle relationship and in the second longitudinal rotation angle relationship, so that a longitudinal rotation angle difference results between the first and second mounting positions. A longitudinal rotation angle is the rotation angle of the support bodies relative to each other about the longitudinal axis of the support bodies.Preferably, the second support body comprises several recesses arranged side-by-side and spaced apart along its longitudinal axis, by means of which a skimmer can be mounted to the second support body. These recesses allow for adjustment of the skimmer's working depth on the second support body. The recesses are preferably designed as bores. An adjustable working depth of the skimmer ensures that its working depth can be adapted to the working depth of a plow body. Preferably, the skimmer is mounted at the desired working depth using a skimmer bracket and repositionable bolts in the bores in the second support body.

[0011] In a preferred embodiment of the support device according to the invention, the first support body and the second support body are designed such that, in the first mounting position, the second support body is arranged on a first side of the first support body, and in the second mounting position, on a second side of the first support body, wherein the first side and the second side of the first support body are preferably arranged opposite each other. Preferably, the second support body also comprises a first side and a second side that are opposite each other. To change from the first to the second mounting position of the support device, the second support body can preferably be moved from the first side of the first support body to the second side of the first support body and from the second side to the first side of the first support body and / or fastened there.Preferably, when changing the mounting position, the first and / or second support body does not rotate substantially 180° around its longitudinal axis.

[0012] In another preferred embodiment of the support device according to the invention, the first support body and the second support body each comprise a mounting area with a first and a second contact surface, wherein the first and the second support bodies are preferably designed such that, in the first mounting position, the first contact surface of the first support body and the first contact surface of the second support body are in contact and preferably mounted together over a flat surface, and in the second mounting position, the second contact surface of the first support body and the second contact surface of the second support body are in contact and preferably mounted together over a flat surface. The first contact surface is preferably located on the first side of each respective support body. The second contact surface is preferably located on the second side of each respective support body.In the assembled state, the mounting areas of the first and second support bodies preferably overlap. The mounting areas are preferably located at the end of the longitudinal path of each support body. In the assembled state, the first and second support bodies are preferably aligned with each other such that their respective longitudinal axes are parallel.

[0013] In a further preferred embodiment of the support device according to the invention, the first contact surface and the second contact surface of the first support body are spaced apart from each other, and / or the first contact surface and the second contact surface of the second support body are spaced apart from each other. The contact surfaces of the first support body preferably have a first contact surface spacing. The contact surfaces of the second support body preferably have a second contact surface spacing. Preferably, the first contact surface spacing corresponds to the material thickness of the first support body, and the second contact surface spacing corresponds to the material thickness of the second support body. In particular, the respective contact surface spacing corresponds to the material thickness of the respective support body in its respective mounting area. Preferably, when changing the mounting position, the support bodies are displaced exclusively in the transverse direction.

[0014] In a further development of the carrier device according to the invention, in the first assembly position, the second contact surface of the first carrier body and the second contact surface of the second carrier body are aligned without contact and facing away from each other, and in the second assembly position, the first contact surface of the first carrier body and the first contact surface of the second carrier body are aligned without contact and facing away from each other. The alignment of the contact surfaces relative to each other is preferably adjusted by implementing a rotational movement of the first and / or the second carrier body.

[0015] A carrier device according to the invention is preferred in which the first and second contact surfaces of the first carrier body are arranged parallel to each other and / or the first and second contact surfaces of the second carrier body are arranged inclined to each other. Preferably, the contact surfaces of the second carrier body are inclined about the longitudinal axis of the second carrier body. In the first assembly position, the second contact surface of the second carrier body is preferably arranged inclined to the first contact surface of the second carrier body and to the first and second contact surfaces of the first carrier body. In the second assembly position, the first contact surface of the second carrier body is preferably arranged inclined to the second contact surface of the second carrier body and to the first and second contact surfaces of the first carrier body.In the first assembly position, the first and second contact surfaces of the first support body and the first contact surface of the second support body are preferably arranged parallel to each other. In the second assembly position, the first and second contact surfaces of the first support body and the second contact surface of the second support body are preferably arranged parallel to each other.

[0016] Furthermore, a support device according to the invention is advantageous in which the first support body and the second support body each have at least two mounting recesses, wherein a first mounting recess of the first support body and a first mounting recess of the second support body form a first pair of recesses, and a second mounting recess of the first support body and a second mounting recess of the second support body form a second pair of recesses. Preferably, the first support body and the second support body can be mounted to one another in the first mounting position via the first pair of recesses and in the second mounting position via the second pair of recesses. The mounting recesses are preferably drilled holes. Preferably, the mounting recesses extend over the entire material thickness of the first and / or the second support body.It is preferable to use different drill holes for different mounting positions, so that mounting is only possible in the two specified mounting positions and the drill holes cannot be mixed up.

[0017] In a further development of the support device according to the invention, the mounting recesses of the first pair of recesses are fully covered in the first mounting position and preferably partially covered in the second mounting position. The mounting recesses of the second pair of recesses are fully covered in the second mounting position and preferably partially covered in the first mounting position. Preferably, the mounting recesses of the first pair of recesses are offset from each other in the second mounting position. Preferably, the mounting recesses of the second pair of recesses are also offset from each other in the first mounting position. If the respective mounting recesses are offset from each other, the mounting recesses have different longitudinal directions and / or the lines of symmetry of the mounting recesses are not collinear with each other.When mounting recesses are partially covered, the usable borehole cross-section is smaller than the borehole diameter of the individual holes in the respective recess pair. Due to the full and / or partial coverage of the mounting recesses, the support bodies can only be connected to each other in two unambiguous mounting positions. This prevents confusion between the two mounting positions.

[0018] In another preferred embodiment of the support device according to the invention, the mounting recesses are arranged in the mounting areas of the first and second support bodies. Preferably, the mounting recesses extend between the contact surfaces of the mounting areas. The mounting recesses are preferably designed such that screw heads and / or nuts have a flat bearing surface on the contact surfaces, in particular by means of recess enlargements that match the screw heads and / or nuts, for example, countersinks of drilled holes.

[0019] In a further preferred embodiment of the support device according to the invention, the second support body has a trapezoidal cross-section in its mounting area. The second support body preferably has a constant cross-section in the longitudinal direction in its mounting area. Preferably, the material thickness of the second support body decreases or increases in a transverse direction in the mounting area. Thus, in the mounting area of ​​the second support body, the material thickness decreases or increases in a wedge shape in the transverse direction of the second support body.

[0020] In a further development of the support device according to the invention, the pre-scooper can be mounted on the second support body such that the position of the pre-scooper is adjustable transversely to the longitudinal axis of the second support body. Preferably, one or more intermediate layers, for example, sheets, can be positioned and / or mounted between a pre-scooper bracket, by means of which the pre-scooper can be mounted on the second support body, and the second support body. The intermediate layers preferably allow the position of the pre-scooper bracket and simultaneously of the pre-scooper arranged on the pre-scooper bracket to be varied in the transverse direction of the second support body. Preferably, the distance of the pre-scooper to the second support body in the transverse direction can be increased by means of the intermediate layers. Preferably, the pre-scooper is positioned substantially parallel to the ground.An intermediate layer can be, for example, between 1 mm and 10 mm thick, particularly 5 mm. The offset of the skimmer by the intermediate layers adjusts the so-called overcut, ensuring that crop residues are reliably conveyed into the furrow. Furthermore, a larger overcut can compensate for wear on the skimmers.

[0021] Furthermore, a support device according to the invention is advantageous, comprising a third support body which is configured to be attached to the first support body opposite the second support body and to carry a further pre-skimmer, wherein the third support body and the first support body can be mounted directly to one another in two mounting positions, and the first support body and the third support body have a first longitudinal rotational angular relationship to each other in the first mounting position and a second longitudinal rotational angular relationship to each other in the second mounting position. The third support body can be configured like the second support body. The first support body preferably comprises a second mounting area at its opposite end, which can be configured like the first mounting area of ​​the first support body. The third support body is preferably mounted in the second mounting area of ​​the first support body.Using the third support body, a second skimmer can be mounted at the end opposite the first support body in the longitudinal direction. On a so-called reversible plow, for example, two skimmers are mounted opposite each other, one at the top and one at the bottom. On such a reversible plow, each pair of skimmers is mounted symmetrically to the frame.

[0022] The problem underlying the invention is further solved by a pre-scooperating device of the type mentioned at the outset, wherein the support device is designed according to one of the preceding embodiments. Regarding the advantages and modifications of the pre-scooperating device according to the invention, reference is made to the advantages and modifications of the support device according to the invention. Preferably, the pre-scooperating device also comprises a third support body, so that a second pre-scooper can be mounted opposite the first pre-scooper.

[0023] In a preferred embodiment of the skimming device according to the invention, the skimmer is rigidly attached to the second support body such that, in the first mounting position of the support device, a first mounting angle is established on the skimmer, and in the second mounting position of the support device, a second mounting angle is established on the skimmer. Preferably, the different mounting positions of the support device during soil cultivation on agricultural land result in different soil throw angles and distances due to the different mounting angles of the skimmer, since the soil penetration of the skimmer changes with the different mounting angles. Preferably, the mounting angle of the skimmer can be changed by an angle between 1 degree and 20 degrees, preferably by 10 degrees, by adjusting the second mounting position.Preferably, the skimmer is attached to the second support body by means of one or more interchangeable bolts and / or one or more screws via recesses arranged side by side and spaced apart along the longitudinal direction of the second support body, wherein the skimmer can be selectively mounted in one or more of the recesses. Mounting the skimmer in one or more of the recesses using interchangeable bolts and / or screws allows for depth adjustment of the skimmer on the second support body.

[0024] In a further development of the skimmer device according to the invention, the position of a skimmer tip of the skimmer with respect to a reference point on the first support body of the skimmer carrier is essentially the same in the first and second mounting positions of the skimmer carrier. Preferably, the distance of the skimmer tip to the plow body is the same in both mounting positions of the support device. Preferably, the tip of the skimmer remains in the same position in each mounting position.

[0025] The problem underlying the invention is further solved by a soil cultivation unit of the type mentioned above, wherein the carrier device is designed according to one of the preceding embodiments and / or the pre-skimming device is designed according to one of the preceding embodiments.

[0026] Preferred embodiments of the invention are explained and described in more detail below with reference to the accompanying drawings. These show: Fig. 1A a support device according to the invention in a first assembly position in a side view; Fig. 1B a support device according to the invention in a second assembly position in a side view; Fig. 2A a peeler device according to the invention with peelers mounted in a first mounting position in a side view; Fig. 2B a peeler device according to the invention with peelers mounted in a second mounting position in a side view; Fig. 3 a mounting area of ​​a first support body of a support device according to the invention in a second mounting position with a skimmer mounted on a second support body in a detailed view from the front; Fig. 4 a mounting area of ​​the second support body which is in the Fig. 3 illustrated support device in a first assembly position in a detailed view from the front; Fig. 5 a support device according to the invention in the first assembly position with non-inclined pre-skimmer in a sectional view; Fig. 6 who are in the Fig. 5.

[0027] The Fig. Figures 1A and B show a carrier device 10 in two different mounting positions.

[0028] The support device 10 comprises a first support body 12, which can be attached to a frame 302 of an agricultural tillage implement 300 by means of screws 33 and nuts 35. Alternatively, in an embodiment not shown, it is also conceivable that the support body 12 can be attached directly to a hydraulic stone protection device or a plow body support. The support body 12 is designed as an elongated square shaft. The support body 12 comprises a mounting area 22a in each of its upper and lower end regions, in which four mounting recesses 28, spaced evenly apart from one another, are arranged. The mounting recesses 28 of the first support body 12 are designed as bores that extend across the entire material thickness in the transverse direction of the support body 12.By means of the mounting recesses 28 in the support body 12, a second support body 14 can be attached to the first support body 12 in the upper mounting area 22a by means of screws 32 and nuts 34, and a third support body 16 can be attached to the first support body 12 in the lower mounting area 22a. The first support body 12 comprises, in its mounting areas 22a, first contact surfaces 24a on its first side 18a and second contact surfaces 26a on its second side 20a.

[0029] The second support body 14 and the third support body 16 each comprise a mounting area 22b in which four mounting recesses 28 are arranged at equal intervals along the longitudinal direction of the support bodies 14, 16. The mounting recesses 28 of the support bodies 14, 16 are designed as bores that extend across the entire material thickness in the transverse direction of the respective support body 14, 16. The mounting recesses 28 in the mounting areas 22b of the second and third support bodies 14, 16 correspond to the mounting recesses 28 in the mounting areas 22a of the first support body 12. The second support body 14 and the third support body 16 each comprise a first contact surface 24b on their respective first side 18b, 18c in their mounting areas 22b and a second contact surface 26b on their respective side 20b, 20c. The contact surfaces 24a, 24b, 26a, 26b are planar. The support device 10 is mirror-symmetrical.

[0030] In Fig. Figure 1A shows the support device 10 in a first assembly position. In this first assembly position, the second support body 14 and the third support body 16 are each attached to the first support body 12 at their first contact surfaces 24b in their mounting areas 22b, forming a flat and contact surface 24a within the mounting areas 22a of the first support body 12. The support bodies 12, 14, and 16 are screwed to each other in the first assembly position by means of mounting recesses 28 on the second support body 14 and the third support body 16, respectively, to two mounting recesses 28 on the first support body 12 provided for the first assembly position. The two mounting recesses 28 on each of the support bodies 14 and 16 correspond to two mounting recesses 28 in each mounting area 22a of the first support body.In the first assembly position, the mounting recesses 28, which are associated with each other, each form a recess pair 30a. The mounting recesses 28 forming each recess pair 30a are positioned relative to each other such that they are fully overlapped, i.e., their bore axes are aligned with each other. In the first assembly position, the remaining, unused mounting recesses 28, intended for the second assembly position, are partially overlapped, so that their bore axes are not aligned with each other and may be arranged at an angle to each other and / or offset. In the first assembly position, the first support body 12 is screwed to the second support body 14 and the third support body 16 such that the contact surfaces 24a, 26a of the first support body 12 are aligned parallel to the surfaces of the second and third support bodies 14, 16, outside the mounting areas 22b of the second and third support bodies 14, 16.

[0031] In Fig. Figure 1B shows the support device 10 in a second assembly position. In this second assembly position, the second support body 14 and the third support body 16 are each attached to the first support body 12 at their second contact surfaces 26b in their assembly areas 22b, forming a flat and contact surface 26a in the assembly areas 22a of the first support body 12. The support bodies 12, 14, and 16 are screwed to the first support body 12 by means of two mounting recesses 28 each in the second support body 14 and the third support body 16, which are provided for the second assembly position. The two mounting recesses 28 of the support bodies 14 and 16 each correspond to two mounting recesses 28 in each assembly area 22a of the first support body.In the second assembly position, the mounting recesses 28, which are associated with each other, each form a recess pair 30b. The mounting recesses 28 forming each recess pair 30b are positioned relative to each other such that they are fully overlapping – their bore axes are therefore in line with each other and form a common axis. In the second assembly position, the remaining, unused mounting recesses 28, intended for the first assembly position, are partially overlapping; their bore axes are thus offset and / or arranged at an angle to each other. In the second assembly position, the first support body 12 is screwed to the second support body 14 and the third support body 16 such that the surfaces of the second and third support bodies 14, 16, located outside the mounting areas 22b of the second and third support bodies 14, 16, are inclined towards the contact surfaces 24a, 26a of the first support body 12.

[0032] Partially covering the mounting recesses 28 not intended for the respective mounting position ensures that the support device 10 can only be mounted in one of the two mounting positions using the screws 32 and nuts 34 provided for mounting. This prevents incorrect assembly and resulting damage to the support device. To prevent tilting and / or twisting of the bolted support bodies 12, 14, 16 relative to each other, one mounting recess 28 is omitted between each of the two mounting recesses 28 used for mounting the support device 10, in order to increase the distance between the mounting recesses 28 used in the longitudinal direction of the support device 10.

[0033] The Fig. Figures 2A and 2B show a pre-peeling device 100 in two different mounting positions. The pre-peeling device 100 comprises the support device 10 made of the Fig. 1A, B. Furthermore, the skimming device 100 comprises two skimmers 102, one skimmer 102 being mounted on the second support body 14 of the support device 10 and the other skimmer opposite it on the third support body 16 of the support device 10. The skimmers 102 are mounted on the second support body 14 and the third support body 16, respectively, by means of a skimmer bracket 104, such that the skimmer tip 108 of the skimmers 102 is oriented away from the support device 10. The skimming device 100 is designed to be mirror-symmetrical.

[0034] The one in Fig. The pre-scooperating device 100 shown in 2A comprises the one shown in the Fig. 1A shows the support device 10 in its first assembly position. The one shown in the Fig. The pre-scooperating device 100 shown in 2B comprises the one described in the Fig. Figure 1B shows the support device 10 in its second mounting position. Because the support device 10 can be mounted in two different positions, the angle of the skimmers 102 mounted on the support device 10 relative to the working direction can be changed. Changing the angle of the skimmers 102 alters the soil throw angle and / or the soil throw distance when the skimmers 102 are used to disturb the soil during tillage on agricultural land. The position of the skimmer tip 108 remains the same when the mounting position of the support device 10 is changed.

[0035] The Fig. Figure 3 shows a detailed view of the mounting area 22a of the first support body 12 with the mounted second support body 14 and a skimmer 102 attached to the second support body 14 by means of a skimmer bracket 104. The first support body 12 and the second support body 14 are mounted together in the second mounting position. In the second mounting position, the mounting recesses 28 of the recess pair 30a are partially overlapped, so that mounting in the second mounting position using the screws 32 is not possible through the recess pair 30a. In the second mounting position, mounting the first support body 12 and the second support body 14 using the screws 32 is only possible through the recess pair 30b.To prevent the first support body 12 from tilting and / or twisting relative to the second support body 14 in the assembly area 22a, two pairs of recesses 30b are used in the second assembly position for screwing the support bodies 12, 14 together, with one pair of recesses 30a being omitted between the pairs of recesses 30b.

[0036] The skimmer 102 is attached to the second support body 14 by means of the skimmer bracket 104. To attach the skimmer bracket to the second support body 14, the second support body comprises several recesses 36 arranged side by side and spaced apart along its length. The skimmer bracket is attached to the second support body by means of one of the recesses 36 and a reversible bolt 106, whereby one of the recesses 36 can be selected for attachment in order to vary the working depth of the skimmer 102 for soil cultivation.By means of an intermediate layer 110, which is arranged between the skimmer console 104 and the second support body 14, the position of the skimmer can be varied transversely to the longitudinal axis of the support device 10 in the extension direction of the recesses 36 in order to change the relative position of the skimmer 102 to a plow body 204 and in this way to adjust the overcut.

[0037] The Fig. Figure 4 shows a detailed view of the mounting area 22b of the second support body 14, which is attached to the first support body 12. The first support body 12 and the second support body 14 are mounted together in the first assembly position. In the first assembly position, the mounting recesses 28 of the recess pair 30b are partially overlapped, so that mounting with the screws 32 through the recess pair 30b is not possible in the first assembly position. In the first assembly position, mounting the first support body 12 and the second support body 14 with the screws 32 is only possible through the recess pair 30a. To prevent the first support body 12 from tilting and / or twisting relative to the second support body 14 in the assembly area 22a, two pairs of recesses 30a are used in the first assembly position for screwing the support bodies 12, 14 together, with one pair of recesses 30b being omitted between the pairs of recesses 30a.

[0038] In Fig. Figure 5 shows a sectional view of the support device 10 assembled in the first assembly position. In the first assembly position, the first contact surface 24a of the first support body 12 and the first contact surface 24b of the second support body 14 are connected to each other by means of the screws 32 and the nuts 34 via the fully overlapping recess pairs 30a. The second contact surface 26a of the first support body 12 and the second contact surface 26b of the second support body 14 are oriented away from each other in the first assembly position. The first contact surface 24a and the second contact surface 26a of the first support body 12 are spaced apart by the material thickness of the first support body 12 and are aligned parallel to each other.The first contact surface 24b and the second contact surface 26b of the second support body 14 are spaced apart by the material thickness of the second support body 12 and are inclined relative to each other. The material thickness of the second support body 14 is reduced trapezoidally in its mounting area 22b in its transverse direction, resulting in the inclined contact surface 26b. Since, in the first mounting position, the non-inclined contact surface 24b of the second support body is attached to the first support body 12 with full contact, a non-inclined mounting angle M1 of 0 degrees is established between the first support body 12 and the pre-skimming bracket 104 and the pre-skimming bracket 102.

[0039] In Fig. Figure 6 shows a sectional view of the support device 10 mounted in the second assembly position. In the second assembly position, the second contact surface 26a of the first support body 12 and the second contact surface 26b of the second support body 14 are connected to each other by means of the screws 32 and the nuts 34 via the fully overlapping recess pairs 30b. The first contact surface 24a of the first support body 12 and the first contact surface 24b of the second support body 14 are oriented away from each other in the first assembly position. Since the inclined contact surface 26b of the second support body is attached to the first support body 12 in the second assembly position, an angle change occurs at the pre-skimming bracket 104 and the pre-skimming bracket 102 relative to the working direction with the mounting angle M2 between the first support body 12 and the pre-skimming bracket 104.Rotating the skimmer 102 around the mounting bracket M2 results in a change in the soil throw angle and distance during soil cultivation. The second mounting position of the support device 10 with the mounting bracket M2 of the skimmer 102 is used, for example, when a different working speed is required when cultivating agricultural land. In the second mounting position, the skimmer tip 108 of the skimmer 102 remains in the same position as in the first mounting position, without any tilting of the skimmer 102.

[0040] The Fig. Figure 7 shows a tillage unit 200, which is designed for use on a reversible plow. The tillage unit 200 comprises two plow bodies 202, which are arranged opposite each other on a plow body carrier 204. The tillage unit 200 also includes a skimmer device 100 according to Fig. 2A with a carrier device 10 and two skimmers 102, which are arranged opposite each other at the upper and lower ends of the carrier device 10 on the support bodies 14, 16 and adjacent to the plow bodies 202. The skimmer device 100 is attached to the plow body carrier 204 by means of screws 35 via the first support body 12 of the carrier device 10. The soil cultivation unit 200 is essentially mirror-symmetrical.

[0041] The Fig. Figure 8 shows an agricultural tillage implement 300 designed as a reversible plow. The tillage implement comprises several tillage units 200 according to Fig.7. The soil cultivation units 200 are arranged at regular intervals in a row on a frame 302 of the soil cultivation implement 300. During cultivation on agricultural land, the soil cultivation implement 300 is pulled by a towing vehicle, for example, a tractor. The skimmers 102 and the plow bodies 202 engage the soil of the field during cultivation. The plow bodies 202 cut furrows into the soil. The skimmers 102 break up the soil immediately in front of the plow bodies 202 and convey soil material from the topsoil layer, including crop residues, into the furrows. By changing the mounting position of the support devices 10 and thus the mounting angle of the skimmers 102, the throwing angle and the throwing distance of the soil material can be adjusted to the ambient conditions or to the working speed of the soil cultivation implement 300.

[0042] In a soil cultivation implement 300 designed as a reversible plow, the frame 302 can be rotated 180 degrees around its longitudinal axis when the direction of travel is changed, so that the plow bodies 202 and skimmers 102 arranged at the top engage in the soil and the plow bodies 202 and skimmers 102 previously arranged at the bottom are moved into the upper position.
