The walking wheels will pass through the normal area where sowing is required and crush it to form a rut area. The depth of the rut area is deeper than the normal area. If the sowing depth is based on the normal area during sowing, the soil above the seeds sown in the rut area will be shallow or even exposed to the surface, resulting in seed leakage, which seriously affects the sowing quality.

DETAILED DESCRIPTION

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0019] The X direction in the accompanying drawings is the forward direction of the tractor.

[0020] Specific embodiments, such as Figure 1-3 As shown, the utility model provides a rutting device for a seed drill, which is fixed to the front end of the seed drill, and the rutting device includes a floating frame and a suspension beam 1, and the floating frame is connected to the sowing beam 2 by means of the suspension beam 1, and the rutting device also includes a rutting plate 3 and a profiling structure, and the profiling structure is connected between the floating frame and the suspension beam 1, and the rutting plate 3 is an arched structure with a protruding middle part, and the arched ends of the rutting plate 3 are fixed ends and are fixedly connected to the floating frame, and the protruding part of the rutting plate 3 is a bulldozer end, and the bulldozer end is hinged to the floating frame by means of a support rod 4, and the rutting plate 3 has the freedom to float up and down by means of the profiling structure and fits into the ground, and the rutting plate 3 moves forward with the tractor and pushes soil to both sides of the covering plate into the rutting to form a covering action.

[0021] The ruts left by the tractor are deep and the walking wheels 15 of the large-scale seeding machine are wide. The walking wheels 15 will pass through the normal area where sowing is required and crush to form a rut area. The depth of the rut area is deeper than the normal area. If the sowing depth is based on the normal area during sowing, the soil above the seeds sown in the rut area is shallow or even exposed to the surface, which will cause seed leakage and seriously affect the sowing quality.

[0022] Therefore, the utility model is provided with a rutting device between the tractor and the seeder, and the rutting plate 3 is used to push the soil forward, and the pushing end of the rutting plate 3 is used to guide the soil to the rutting on both sides to fill the depression of the rutting, complete the soil covering, make the soil surface flat, avoid the seeds being exposed to the ground, keep the seed sowing depth uniform, and improve the sowing quality.

[0023] At the same time, since the soil layer has an uneven topography, in order to allow the rutting to better adapt to the terrain and to fluctuate with the changes in the soil layer topography so as to always adhere to the soil layer and act on the ground, the rutting device in the present invention is also provided with a profiling structure. The profiling structure can enable the rutting plate 3 to have the freedom to elastically float up and down, thereby preventing the rutting plate 3 from separating from the ground surface, causing the pushed soil to be lost along the gap between the rutting plate 3 and the ground surface, and resulting in a lack of soil to fill the subsequent rutting.

[0024] The track plate 3 is arched in a V-shape, with its tip facing the direction of travel. The bifurcated ends of the track plate 3 serve as its fixed ends, fixedly connected to the floating frame. The tip of the track plate 3 serves as its pusher end, hingedly connected to the support rod 4. The V-shaped track plate 3 guides soil. As more soil is pushed and the track plate 3 continues to advance, soil at the pusher end of the track plate 3, guided by the plates on both sides, gradually flows toward the fixed end of the track plate 3, ultimately flowing into the pit formed by the rut.

[0025] The contouring structure includes a first and second parallel connecting rods 5 and 6, as well as a fixed arm 7 and a floating arm 8. The first and second connecting rods 5, 6, fixed arm 7, and floating arm 8 are hingedly connected to form a parallelogram structure. The fixed arm 7 and floating arm 8 are respectively arranged in a vertical direction. The fixed arm 7 is fixedly connected to the suspension beam 1, and the floating arm 8 is hingedly connected to the fixed arm 7 via the first and second connecting rods 5 and 6. The floating frame is located between the floating arms 8 on both sides. The fixed arm 7 is fixed, while the floating arm 8 is always in translation due to the contouring structure. That is, the floating arm 8 is always in a vertical state. Therefore, the track plate 3 does not produce angular deflection during the up and down floating process, ensuring that the track plate 3 always conforms to the ground surface.

[0026] The top of the floating arm 8 is also provided with an elastic regulator, which includes a limit rod 9 and a first compression spring 10 and a second compression spring 11 sleeved on the limit rod 9. The suspension beam 1 is provided with a limit groove 12 for the limit rod 9 to pass through. The limit groove 12 is in the shape of an oblong hole. The suspension beam 1 avoids the limit rod 9 during the up and down floating process with the help of the limit groove 12. The first compression spring 10 and the second compression spring 11 are respectively located on the upper and lower sides of the suspension beam 1. The first compression spring 1 0 and the fixed end of the second compression spring 11 are fixedly connected to the limit pull rod 9 respectively, the telescopic end of the first compression spring 10 and the telescopic end of the second compression spring 11 are respectively directed toward the suspension beam 1 and abut against the suspension beam 1, and the floating arm 8 has the freedom to float up and down with the help of the elastic adjuster. When the track plate 3 passes through a bumpy soil section, the elastic adjuster can filter out the bumps of the track plate 3, so that the track plate 3 always fits the ground surface.

[0027] The floating frame comprises a support beam 13 and a connecting beam 14 arranged parallel to each other. The ends of the support beam 13 and the connecting beam 14 are fixedly connected to the floating arms 8 on either side. The support beam 13 is located above the connecting beam 14, and the fixed end of the track plate 3 is fixedly connected to the connecting beam 14. The support rod 4 is arranged at an angle along the forward direction, and its ends are hinged to the support beam 13 and the bulldozing end of the track plate 3. In this embodiment, the support rod 4 is a turnbuckle, and the initial height of the track plate 3 can be adjusted by adjusting the extension and contraction of the turnbuckle.

[0028] The bottom surface of the connecting beam 14 is located at the same horizontal plane as the bottom surface of the rutting plate 3. The width of the connecting beam 14 is greater than the width of the rutting plate 3. The connecting beam 14 moves forward with the tractor and passes through and flattens the rutting covered with soil to form a soil leveling action. In addition to playing the role of fixed support, the connecting beam 14 also has the function of leveling the soil, which can be used to scrape the soil covered in the rutting to make the soil surface flat.
