Description

[0001] The present invention relates to a seeding device. More precisely, the present application relates to a seeding device as an attachment for a plow.

[0002] The present application aims to provide a seeding device, a plow with a seeding device, and a soil cultivation method with which simple sowing can be carried out directly during plowing. This objective is achieved by the attached independent claims.

[0003] According to one aspect of the present application, a seeding device for attachment to a plow comprises a finishing unit, a seeding unit, and fastenings. The seeding unit is at least partially mounted on the finishing unit, and the finishing unit is movably connected to the fastenings.

[0004] The finishing unit can comprise one or more tines, discs, wheels, and rollers. Finishing units typically follow the plowshares. Their function is, for example, to break up the plowed clods of earth and / or to reconsolidate the plowed soil. The seed drill can be used, for example, for sowing cover crops, as a precise seed pattern is not paramount in this case. The seed drill has the advantage that soil preparation can be completed in a single pass: plowing, finishing, and sowing. This protects the soil and reduces fuel consumption. The attachments can be adjustable, for example, in length.

[0005] According to one aspect of the present application, the seeding unit of a seeding device comprises at least one distributor which applies the seed to the area of ​​the follow-up unit. For example, the seed is applied after the plowshares and in the area of ​​the follow-up unit. Since the follow-up unit intervenes in the soil structure again, it is advantageous to apply the seed in this area, as at least a portion of the seed is incorporated into the soil by the follow-up unit.

[0006] According to one aspect of the present application, the seeding unit of the seed drill comprises distributors arranged on the finishing unit. These distributors can be directed seeders, such as seed horns, seed coulters, or seed tines. Alternatively, they can be non-directional distributors that distribute the seed in a 360° arc. This 360° distribution can be limited by deflector plates, so that the seed is distributed, for example, in the direction of plowshares and / or areas adjacent to the finishing unit (e.g., outside its working area) are not reached by the distribution. The distributors can be in contact with the soil or operate without soil contact. This is advantageous because it allows for improved and customized seeding pattern and incorporation into the soil.

[0007] According to one aspect of the present application, the seeding unit of a seeding device includes a data interface. This is advantageous because it allows the seeding unit to be remotely controlled, for example, by a tractor. It is also possible to control the seeding device using GPS-based data, such as the seeding rate.

[0008] According to one aspect of the present application, the seeding unit of a seeding device comprises a container which is arranged on the finishing unit or on at least one of the mountings. This is advantageous because it allows the seeding device to be designed compactly and, for example, eliminates the need for connections from the tractor to the seeding device.

[0009] According to one aspect of the present application, the post-cultivation unit of a seed drill comprises a raking unit. The raking unit has several tines extending from it. The raking unit is movably connected to the mountings. The tines allow the post-cultivation unit to modify the soil structure achieved by plowing (e.g., to break up clods). This is advantageous for the quality of soil cultivation and seed placement.

[0010] According to one aspect of the present application, at least one fastening is length-adjustable. This is advantageous because it allows the projection of the seeding device to be varied.

[0011] According to one aspect of the present application, a plow comprises a seeding device as described above.

[0012] According to one aspect of the present application, the post-cultivation unit of a plow is arranged behind the plowshares. This is advantageous for the quality of soil cultivation and seed placement.

[0013] According to one aspect of the present application, the post-cultivation unit of a plow is designed and suitable to pivot over the plowshares or together with the plow when the plow is turned. This is advantageous for reversible plows, as the seeding device can pivot over the plowshares without restricting the process or causing any additional effort, for example, for assembly or disassembly. It is also advantageous if the seeding device can pivot or rotate with the plow, as this allows the plow with the seeding device to be brought into, for example, a transport position and pivoted upwards when the plow is turned.

[0014] According to one aspect of the present application, a container is arranged on the plow frame of a plow. The plow frame refers to the elongated part of a plow to which the plowshares are attached (possibly with the interposition of further parts). The plow frame may include a swivel head to which the container may also be attached. This is advantageous because the weight of the container can be positioned favorably.

[0015] According to one aspect of the present application, the post-harvesting unit of a plow is aligned with the plowshares. This can be a parallel alignment with the plow frame, where "parallel" is to be understood in a broader sense, since it may be advantageous not to align the post-harvesting unit at a constant distance from the plowshares, but with a deviation.

[0016] According to one aspect of the present application, a soil cultivation method using a plow is disclosed, wherein in a single pass the soil is plowed, subsequently cultivated, and seed is sown into the soil in the area of ​​subsequent cultivation. This means that in one pass, e.g., with a tractor, the aforementioned steps are carried out, and thus, for example, a field only needs to be traversed once. This is advantageous because it protects the soil and the environment. For example, a cover crop can be sown.

[0017] According to one aspect of the present application, a soil cultivation method is disclosed, wherein the subsequent cultivation includes reconsolidation. This can have the advantage that the sown seed is at least partially incorporated into the soil.

[0018] According to one aspect of the present application, sowing can be carried out in an undirected manner via distributors located in the post-cultivation area. A seed supply can also be located in the post-cultivation area. This can have the advantage of making the process easy to implement and delivering good results.

[0019] To better understand the invention, it is explained in more detail with reference to the following figures. These show, in a highly simplified, schematic representation: Fig. 1 A top view of a plow with seeding device according to an exemplary embodiment. Fig. 2 a side view of the plow from Fig. 1.

[0020] It should be noted at the outset that identical parts in the differently described figures are designated with the same reference numerals or component designations, and that the disclosures contained in the entire description can be applied analogously to (functionally) identical parts with the same reference numerals or component designations. Furthermore, the positional designations chosen in the description, such as top, bottom, side, etc., refer to the directly described and illustrated figure or to a plow standing on a horizontal plane, and these positional designations are to be applied analogously to any change in position. Due to the purely schematic nature of the representation, no scales or ratios can be derived from this. The disclosed method is given in conjunction with the following device description.

[0021] Initially, reference is made to Fig. Figure 1 shows a plow 100 with a seeding device 10 in a schematic and highly simplified top view (the ground – not shown – would be parallel to the blade plane). The plow 100 includes a mounting 130 with which the plow 100 can be attached, for example, to a tractor (not shown) in a manner typical of the type (thus the working direction of the plow 100 is to the left). Fig. 1, parallel to the arrow shown on the recording 130). Furthermore, the plow 100 comprises a plow frame 120 to which plowshares 110 are attached. The plow frame 120 forms an acute angle to the above working direction. The plow 100 is a reversible plow. The seeding device 10 also includes a data interface 32.

[0022] Two mountings 40 are attached to the plow frame 120, to which the post-cultivation unit 20 is movably attached. In the example shown, this post-cultivation unit is a screening unit 21. The screening unit 21 is pivotally arranged between the mountings 40 about its longitudinal axis. This allows it to pivot, for example, when stones have been brought to the surface by the plowshares. Distributors 31 and a container 33 connected to them are arranged on the screening unit 21. The distributors 31 distribute seed randomly and all around the post-cultivation unit 20. The distribution can also be restricted, e.g.,by means of deflector plates, so that the seed is distributed in an undirected manner in the direction of the plowshares 110 and / or the seed is not distributed outside a working area in the working direction of the post-processing unit 20, so that seed accumulation does not occur or is reduced in parallel working passes in the edge areas.

[0023] In Fig. Figure 2 is a schematic side view of the plow 100 with seeding device 10. Fig. Figure 1 shows that the plow 100 is shown in comparison to the Fig. Figure 1 shows the plough frame 120 rotated by 90°, as is known for reversible ploughs. The tines 22 of the calculating unit 21 are also partially shown. Furthermore, the orientation of the finishing unit 20 in relation to the ploughshares 110 is visible in both figures. This orientation is essentially parallel to the plough frame 120, but not in a precise mathematical sense. The in Fig. The mounting 40 shown on the left is shorter than the mounting 40 shown on the right. However, the mountings 40 can be adjusted in length, for example to change the alignment of the finishing unit 20 to the plowshares 110 and / or to make the finishing unit 20 as compact and low-profile as possible for road transport (as, for example, in Fig. 2 shown). By means of a shorter front (in Fig.(2 left) The height is reduced by the container 33. The fixings 40 can be movably (e.g. pivotably) attached to the plow frame 120, or fixedly connected to it, as in the described embodiment.

[0024] When a field is plowed with the plow 100 described above, the plowshares 110 plow the soil in the usual way. This soil is then worked by the post-cultivation unit 20, and seed is applied to the soil in the area of ​​the post-cultivation unit 20 by the seeding device 10. All of this happens in a single pass of the plow 100, so only one pass is required.

[0025] The exemplary embodiment shows one possible embodiment, although it should be noted here that the invention is not limited to the specifically illustrated embodiment, but rather various combinations of the individually disclosed features are also possible. Not all features need to be present in every instance. This possibility of variation lies within the capabilities of a person skilled in this technical field, due to the teaching of technical action provided by the present invention.

[0026] The scope of protection is defined by the claims. However, the description and drawings must be consulted for the interpretation of the claims. Individual features or combinations of features from the different embodiments shown and described can, in themselves, represent independent inventive solutions. The problem underlying these independent inventive solutions can be found in the description.

[0027] Finally, for the sake of clarity, it should be noted that, for a better understanding of the structure, some elements have been shown not to scale and / or enlarged and / or reduced in size, and dimensions can only be derived where this is explicitly described.
