Then, the tractor pulls the horizontal plate 1 to the sowing land. Then, the first rocker wheel 10 and the second rocker wheel 13 are rotated to adjust the height of the covering plate 7 and the turning shovel 8 respectively. The first rocker wheel 10 drives the first lead screw 9 to rotate. The first lead screw 9 moves relative to the first screw hole under the action of the thread.

The rear end of the rotating shaft 16 is fixedly connected to the first bevel gear 18. The first bevel gear 18 meshes with the adjacent second bevel gear 20. The third bevel gear 24 is close to the bottom of the second transmission rod 22. The third bevel gear 24 meshes with the adjacent second bevel gear 20. The fourth bevel gear 25 is set at a height lower than the bottom of the horizontal plate 1.

[0026] The top end of the second drive rod 22 is fixedly fitted with a first grooved wheel 26. The inner cavity of the cylinder 3 is provided with a first driven rod 30. The top end of the first driven rod 30 is fixedly fitted with a second grooved wheel 27. A belt 28 is provided between the first grooved wheel 26 and the second grooved wheel 27. The first grooved wheel 26 and the second grooved wheel 27 are connected by transmission through the belt 28. The top of the cylinder 3 is fixedly connected with a mounting plate 29. The first driven rod 30 is rotatably connected to the mounting plate 29. Several stirring blades 31 are fixedly connected to the outer edge of the first driven rod 30. The operation of the above embodiment is as follows: when seeds and pesticides are placed together inside the cylinder 3, and the cross plate 1 is pulled by a tractor, the roller 17 rolls on the ground. The roller 17 drives the first bevel gear 18 to rotate through the shaft 16. The first bevel gear 18 drives the first transmission rod 19 to rotate through the second bevel gear 20. The first transmission rod 19 drives the second transmission rod 22 to rotate through the second bevel gear 20 and the third bevel gear 24. The second transmission rod 22 drives the fourth bevel gear 25 and the first grooved wheel 26 to rotate. The first grooved wheel 26 drives the first driven rod 30 to rotate through the belt 28 and the second grooved wheel 27. The first driven rod 30 mixes and stirs the seeds and pesticides through the stirring blade 31.

[0027] When the roller 17 of the device is rolling, its power can be transmitted to the stirring blade 31, and the seeds and pesticides are mixed and stirred by the stirring blade 31, which saves the use of driving equipment and makes it easier to mix seeds and pesticides.

[0028] Example 3: Please see Figure 9-13A cylindrical shell 32 is fixedly connected to the bottom of the cylinder 3. A discharge pipe 33 is fixedly inserted into the bottom of the cylindrical shell 32. A disc 34 is provided in the inner cavity of the cylindrical shell 32. A through hole 35 is opened on the disc 34. A second driven rod 36 is fixedly connected to both the front and rear sides of the disc 34. A fifth bevel gear 37 is fixedly sleeved on the rear second driven rod 36. The fourth bevel gear 25 and the fifth bevel gear 37 mesh with each other. The second driven rod 36 is rotatably connected to the cylindrical shell 32. The length of the rear second driven rod 36 is greater than that of the front second driven rod 36.

[0029] The operation of the above embodiment is as follows: When the fourth bevel gear 25 rotates, it drives the second driven rod 36 to rotate through the fifth bevel gear 37. The second driven rod 36 drives the disc 34 to rotate. When the disc 34 rotates, it drives the perforation 35 to correspond with the cylinder 3 and the discharge pipe 33 respectively. The seeds inside the cylinder 3 pass through the perforation 35 and are discharged from the discharge pipe 33. That is, the rotating disc 34 can discharge seeds intermittently. After the soil turning shovel 8 turns the soil, the seeds are scattered on the turned soil. The covering plate 7 then covers the soil, thereby covering the seeds.

[0030] When the roller 17 of the device is rolling, its power can be transmitted to the disc 34. The rotating disc 34 can intermittently release seeds. After the soil is turned over by the turning shovel 8, the seeds are scattered on the turned soil. The covering plate 7 then covers the soil, thereby covering the seeds and greatly improving work efficiency.

[0031] When seeds and pesticides are placed together inside cylinder 3, and the cross plate 1 is pulled by a tractor, roller 17 rolls on the ground. Roller 17 drives the first bevel gear 18 to rotate via shaft 16. The first bevel gear 18 drives the first transmission rod 19 to rotate via the second bevel gear 20. The first transmission rod 19 drives the second transmission rod 22 to rotate via the second bevel gear 20 and the third bevel gear 24. The second transmission rod 22 drives the fourth bevel gear 25 and the first grooved wheel 26 to rotate. The first grooved wheel 26 drives the first driven rod 30 to rotate via belt 28 and the second grooved wheel 27. The first driven rod 30 mixes and stirs the seeds and pesticides via stirring blade 31.

[0032] When the roller 17 of the device is rolling, its power can be transmitted to the stirring blade 31, and the seeds and pesticides are mixed and stirred by the stirring blade 31, which saves the use of driving equipment and makes it easier to mix seeds and pesticides.

[0033] When the fourth bevel gear 25 rotates, it drives the second driven rod 36 to rotate via the fifth bevel gear 37. The second driven rod 36 drives the disc 34 to rotate. When the disc 34 rotates, it drives the perforation 35 to correspond with the cylinder 3 and the discharge pipe 33 respectively. Seeds inside the cylinder 3 pass through the perforation 35 and are discharged from the discharge pipe 33. That is, the rotating disc 34 can discharge seeds intermittently. After the soil turning shovel 8 turns the soil, the seeds are scattered on the turned soil. The covering plate 7 then covers the soil, thereby covering the seeds.

[0034] When the roller 17 of the device is rolling, its power can be transmitted to the disc 34. The rotating disc 34 can intermittently release seeds. After the soil is turned over by the turning shovel 8, the seeds are scattered on the turned soil. The covering plate 7 then covers the soil, thereby covering the seeds and greatly improving work efficiency.

[0035] In this invention, an elastic scraper 38 is fixedly connected to the top of the inner cavity of the circular shell 32. The bottom of the elastic scraper 38 is tightly fitted to the top of the circular disc 34, and the length of the elastic scraper 38 is adapted to the radius of the circular disc 34. The elastic scraper 38 is made of silicone material. In this invention, the elastic scraper cleans the seeds remaining on the surface of the circular disc in real time, avoiding the accumulation of seeds outside the perforations that leads to inaccurate seeding, thus solving the problem of decreased seeding accuracy caused by seed residue in traditional circular disc seeding.

[0036] In this invention, the bottom of the soil covering plate 7 is provided with an arc-shaped groove 39. A plurality of elastic protrusions 40 are evenly distributed within the inner cavity of the arc-shaped groove 39. The cross-section of each elastic protrusion 40 is semi-circular, and the elastic protrusions 40 and the soil covering plate 7 are integrally formed. In this invention, the arc-shaped groove reduces soil resistance during soil covering, and the elastic protrusions can perform secondary sorting of the soil, making the covered soil more uniform and loose, thus avoiding the soil clumping phenomenon that easily occurs with traditional flat soil covering plates.

[0037] In this invention, a plurality of inclined guide plates 41 are fixedly connected to the inner cavity sidewall of the cylinder 3. The inclination direction of the guide plates 41 is adapted to the rotation direction of the stirring blades 31, and a plurality of through holes 42 are formed on the surface of the guide plates 41. In this invention, the guide plates and the stirring blades work together to guide the seeds to flow to the bottom of the cylinder and to achieve layered mixing of seeds and pesticides through the through holes, thereby improving the mixing uniformity and solving the problem of insufficient mixing in traditional single stirring blades.

Step D: Start the traction device. Roller 17 rolls, driving shaft 16 and first bevel gear 18 to rotate. Power is transmitted to second transmission rod 22 via second bevel gear 20, first transmission rod 19, and third bevel gear 24. Second transmission rod 22 drives first grooved wheel 26 and fourth bevel gear 25. First grooved wheel 26 drives first driven rod 30 to rotate via belt 28. Stirring blade 31 and guide plate 41 work together to mix materials. After mixing, the mixture falls through through hole 42. Fourth bevel gear 25 drives disc 34 to rotate via fifth bevel gear 37. Perforation 35 intermittently aligns cylinder outlet and discharge pipe 33 to achieve quantitative seed discharge. Elastic scraper 38 cleans residue from disc surface.
