[0019] Example 1, see appendix Figures 1-3 An external-mounted auxiliary cleaning device for a corn planter includes a frame 1 and two cleaning wheels 2 symmetrically arranged in front of the frame. Two longitudinal rods 11 are hinged side-by-side at the top of the frame 1. A vertical support 13 is fixedly connected between the outer ends of the two upper support rods. The longitudinal rods 11 and the vertical support 13 form an L-shaped frame structure. A transverse rod 14 is provided at the bottom of the vertical support 13, with both ends of the transverse rod 14 extending out from the two sides of the vertical support 13. Both ends of the transverse rod 14 are connected to inclined wheel frame rods 15. The cleaning wheels 2 include an inner wheel disc 21, an outer wheel disc 22, and a wheel rim 23. The inner wheel disc 21 and the outer wheel disc 22 are arranged concentrically side-by-side. The two are fixedly connected as one unit by a support ring. The wheel rim 23 is concentrically fitted on the outer side of the two wheel discs. Several rake teeth 24 are evenly distributed on the wheel rim 23. The inner end of the rake teeth 24 is fixedly connected between the two wheel discs, and the outer end extends out of the circumferential side of the wheel rim 23. A seated bearing 25 is provided in the middle of the outer wheel disc 22. A wheel axle is installed in the seated bearing 25. The wheel axle extends outward from the seated bearing 25 by a certain length. The wheel axle is connected to the bushing at the end of the wheel frame rod 15. The two cleaning wheels 2 are arranged at an angle towards each other. The lower part of the inner end of the two cleaning wheels 2 is close to each other and is located on the corn planting route. Therefore, it can clean up the larger corn stalks on the planting route.

[0020] The rake tooth 24 is V-shaped. The inner end of the rake tooth 24 is fixedly connected between the inner wheel 21 and the outer wheel 22, and the outer end is inclined in the opposite direction of the rolling of the cleaning wheel 2. The rake tooth 24 has a certain degree of flexibility, so it can generate elasticity to pull the corn stalks away a certain distance and keep them away from the corn planting path.

[0021] The longitudinal rod 11 is hinged to the top of the bracket 1. A reinforcing rod 12 is provided between the ends of the two longitudinal rods 11. The bottom of the bracket 1 is provided with a seat plate 16. A telescopic push rod 17 is hinged between the seat plate 16 and the reinforcing rod 12. The telescopic push rod 17 is a hydraulic cylinder or an electric push rod. The longitudinal rod 11 is raised or lowered by the telescopic push rod 17 to adjust the overall height of the device. After sowing, it can be raised and walked on the road without having to be disassembled and transported separately.

[0022] In this embodiment, the cleaning device is used with the frame 1 attached to the front of the corn planter. As the planter moves forward and sows, the rake teeth 24 on the two symmetrically arranged cleaning wheels 2 contact the ground surface, continuously pushing the corn stalks to both sides. The corn stalks along the sowing path are cleared, preventing them from obstructing the planter's seeding process and effectively improving the quality of corn sowing.

[0023] Example 2, see appendix Figures 2-4 This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that: the end of the horizontal bar 14 is provided with a hinge seat 36, and the wheel frame bar 15 is hinged in the hinge seat 36. This hinge structure allows the cleaning wheel 2 to swing up and down to adapt to the undulations of the ground and ensure that it is in full contact with the ground. An auxiliary horizontal bar 31 is provided on the upper part of the inner side of the vertical support 13. The end of the auxiliary horizontal bar 31 is connected to a limit bar 38. A vertical bar 32 is provided between the limit bar and the horizontal bar 14. The lower end of the vertical bar 32 is hinged to the wheel frame bar 15, and the upper end slides through the limit bar 38. An annular baffle 33 is provided in the middle of the vertical bar 32. A spring 34 is sleeved on the vertical bar 32 between the annular baffle and the limit bar. A handwheel 35 is threadedly connected to the protruding part of the vertical bar 32. The spring 34 provides downward pressure to the vertical rod 32, which slides down along the limiting rod 38, transmitting the elastic pressure to the frame rod below, and then applying the elastic pressure to the cleaning wheel 2. During the walking and cleaning process, the cleaning wheel 2 is always pressed firmly to the ground to prevent it from bouncing and missing some corn stalks, ensuring that the corn stalks on the planting route are cleared and cleaned.

[0024] Furthermore, the sliding stroke of the vertical rod 32 can be adjusted by the handwheel 35, and the elastic support force of the spring 34 can be changed to adjust the elastic pressure on the cleaning wheel 2. When the density of corn stalks on the ground is high, the elastic pressure of the cleaning wheel 2 is increased, and when the density of corn stalks on the ground is low, the elastic pressure of the cleaning wheel 2 is decreased, thereby changing the gripping force of the rake teeth 24 to achieve the best cleaning effect.

[0025] The hinge seat 36 has several holes 37 evenly arranged along its length. The wheel frame rod 15 is connected to one of the holes 37 by a pin. By connecting the wheel frame rod 15 to different holes 37, the overall height of the wheel frame rod 15 can be adjusted, thereby adjusting the height of the cleaning wheel 2. If the corn stalk density is high, it can be adjusted to be lower, and if the density is low, it can be adjusted to be higher.

[0026] Example 3, see appendix Figures 2-4This embodiment is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that: the end of the limiting rod 38 is provided with a square tube sleeve 41, which slides onto the auxiliary crossbar 31. The square tube sleeve 41 is provided with a set screw 42. The limiting rods 38 on both sides slide along the limiting rods 38 through the square tube sleeve 41 to adjust the distance between the two limiting rods 38. After adjustment, the square tube sleeve 41 is locked with the set screw 42 to realize the adjustment and locking of the limiting rods 38; the end of the wheel frame rod 15 is provided with a square tube sleeve 43, which slides along the limiting rod 38 through the square tube sleeve 41 to adjust the distance between the two limiting rods 38. The square sleeve B43 is slidably mounted on the transverse rod 14. The square sleeve B43 is equipped with a set screw B44. The wheel frame rods 15 on both sides slide along the transverse rod 14 through the square sleeve B43 to adjust the distance between the two wheel frame rods 15. After adjustment, the square sleeve B43 is locked with the set screw B44 to achieve the adjustment and locking of the wheel frame rods 15. The distance between the two cleaning wheels 2 is adjusted by adjusting the distance between the wheel frame rods 15 and the limiting rod 38, so that it can be adaptively adjusted according to the coverage density of corn stalks on the land, which has the advantages of flexible use and operation.
