Technical Field
[0001] The utility model relates to the technical field of seeders, in particular to a soil covering device for a dryland corn seeder. Background Art
[0002] A seeder is a planting machine that uses crop seeds as the seeding object. After a corn seeder opens a furrow and sows seeds, a soil covering device is required to perform a soil covering operation on the sowing furrow to bury the seeds inside the sowing furrow.
[0003] The existing soil covering device has a simple structure, including two symmetrically arranged soil covering disc components, and only has the function of covering soil. It can only gather the soil on both sides of the surface layer of the sowing furrow inward through the soil covering discs, but cannot gather the soil on both sides of the bottom of the sowing furrow, and cannot cause the sowing furrow to close due to extrusion. As a result, there is still a narrow strip-shaped gap at the bottom of the sowing furrow, causing the crop roots to preferentially grow horizontally along the strip-shaped gap, affecting the growth of crops. Although the compaction device can compact the soil, considering that the soil cannot be over-compacted, when the sowing depth is relatively deep, the gap at the bottom of the sowing furrow still cannot be effectively filled with soil.

[0035] Embodiment: Refer to Figures 1-7 A soil covering device for a dryland corn seeder shown in the figure, which includes two symmetrically arranged soil covering discs 1. One side of the soil covering disc 1 is fixed with an adjustment cavity 2. One side of the adjustment cavity 2 is provided with an end cover 5. A side deep pressure application assembly 10 is fixed at the bottom inside the adjustment cavity 2;
[0036] The side deep pressure application assembly 10 includes a circular plate 101 fixed to the inner wall of the adjustment cavity 2. A plurality of square cylinders 102 are fixed to the circumferential side surface of the circular plate 101. A pressure application plate 103 is slidably fitted in the square cylinder 102. A relief groove 104 is formed on one side of the square cylinder 102. A cylinder 105 is fixed to one side of the pressure application plate 103. The cylinder 105 is slidably fitted inside the relief groove 104. One end of the pressure application plate 103 slidably penetrates through the adjustment cavity 2;
[0037] One side of the side deep pressure application assembly 10 is rotatably connected to a drive assembly 9 for synchronously driving the sliding of a plurality of cylinders 105. A rotating shaft 6 is fixed to one side of the drive assembly 9. The rotating shaft 6 penetrates through the end cover 5 and is rotatably connected to the end cover 5. A locking assembly 8 for restricting the rotation of the rotating shaft 6 is provided on one side of the end cover 5;
[0038] As Figure 1 shown, the bottom of the soil covering disc 1 inclines inwards. A bracket 3 is provided between the two soil covering discs 1. A mounting plate 4 is fixed to the top of the bracket 3. The soil covering disc 1 is rotatably connected to one side of the bottom end of the bracket 3.
[0039] The device is fixed to the seeder through the mounting plate 4. During the soil covering operation, the two soil covering discs 1 will rotate forward at a certain speed. The two soil covering discs 1 will gather and cover the soil on both sides of the surface layer of the sowing furrow. The drive assembly 9 can drive a plurality of cylinders 105 to slide out synchronously inside the relief groove 104. The sliding of the cylinder 105 will drive the pressure application plate 103 to slide inside the square cylinder 102. The pressure application plate 103 can be slid out to a specific length as required. After locking the rotating shaft 6 through the locking assembly 8, the drive assembly 9 and the cylinder 105 will be locked together, and the pressure application plate 103 cannot slide freely. During the soil covering process, the end of the pressure application plate 103 will incline downwards and extend into the soil interior. The pressure application plates 103 on the two soil covering discs 1 squeeze the soil from both sides towards the bottom of the sowing furrow at the same time, so that the gap at the bottom of the sowing furrow is closed under the extrusion force, improving the soil covering effect, being easy to adjust, being able to adapt to the soil covering needs of sowing furrows with different depths, and being more beneficial to the growth of crop roots.
[0040] In order to enable the drive assembly 9 to drive the cylinder 105 to slide inside the relief groove 104, in this embodiment, the drive assembly 9 includes a rotating plate 91 rotatably connected to one side of the circular plate 101. A plurality of arc-shaped pressing plates 92 are fixed to the circumferential side surface of the rotating plate 91. An arc-shaped pressing groove 93 is formed on one side of the arc-shaped pressing plate 92. The cylinder 105 is located inside the arc-shaped pressing groove 93 and is slidably fitted with the arc-shaped pressing groove 93. The rotating shaft 6 is fixed to one side of the rotating plate 91. The number of arc-shaped pressing plates 92 is the same as the number of pressure application plates 103. When the rotating shaft 6 is rotated, the rotating plate 91 will rotate synchronously with the rotating shaft 6. The arc-shaped pressing plates 92 rotate with the rotating plate 91. The cylinder 105 inside the arc-shaped pressing groove 93 will be squeezed and slide to one side, thereby driving the cylinder 105 to slide inside the relief groove 104.
[0041] In order to improve the soil-breaking ability of the pressing plate 103, in this embodiment, one end of the pressing plate 103 is provided with a blade, and a set of springs 106 are fixed between the other end of the pressing plate 103 and the inner bottom wall of the square cylinder 102. The arrangement of the springs 106 can make the pressing plate 103 receive a certain resistance during the sliding process. This resistance makes the rotating shaft 6 not easy to rotate, reduces the flexibility when the driving assembly 9 rotates, and helps the operator to finely adjust the rotation angle of the driving assembly 9.
[0042] In order to enable the locking assembly 8 to lock the rotating shaft 6, in this embodiment, the locking assembly 8 includes two side plates 81 and two symmetrically arranged locking plates 82. One end of the side plate 81 is fixed to one side of the end cover 5, and the two side plates 81 are located on both sides of the rotating shaft 6. A fastening screw 83 is fixed to the outside of the locking plate 82. The fastening screw 83 slidably penetrates through the side plate 81, and the two locking plates 82 are fixedly connected by the fastening screw 83. The sliding fit between the side plate 81 and the fastening screw 83 enables the locking plate 82 to be fixed to one side of the end cover 5. The two locking plates 82 are symmetrically arranged with respect to the rotating shaft 6, and an arc-shaped plate for wrapping the rotating shaft 6 is provided on the locking plate 82. One end of the rotating shaft 6 is fixed with an adjusting plate 7, and the arrangement of the adjusting plate 7 facilitates the operator to control the rotation of the rotating shaft 6. By tightening the fastening screw 83, the arc-shaped plates of the two locking plates 82 can tightly clamp and fix the outside of the rotating shaft 6, and the rotating shaft 6 is locked by the clamping force to prevent it from rotating.
