8. A planting method of a soybean planting device, characterized in that: The steps include: S1. Preparation: pour the soybean seeds to be planted into the hopper (308), then rotate the screw rod (317) to move the slider (314) to the desired position in the receiving groove (306), loosen the bolt (212), adjust the stopper (208) to a suitable position, and then tighten the bolt (212) to fix it; S2, positioning and unloading: Grab the handle 1 (405) and lift the rear end of the mounting plate (101) so that the supporting leg (105) leaves the ground, and then push the device forward. When the device moves forward, the wheel (104) rotates, driving the rotating shaft 1 (103) connected thereto to rotate. The rotating shaft 1 (103) drives the rotating shaft 2 (202) to rotate through the belt transmission component 1 (203). The rotating shaft 2 (202) causes the rack 1 (205) to slide on the L-shaped plate (206) through the gear 1 (204). When the rack 1 (205) moves to the stopper (208), it is blocked, so that the device cannot continue to move forward. During this process, the rack gear 2 (313) fixedly connected to the rack gear 1 (205) moves synchronously and drives the gear gear 2 (312) meshing therewith to rotate at a certain angle. The rotating shaft 3 (310) fixedly connected to the gear gear 2 (312) drives the rotating sleeve (304) to rotate at a certain angle through the belt transmission component 2 (309). The rotating sleeve (304) drives the rotating disk (305) fixedly connected thereto to rotate, so that the soybean seeds in the receiving groove (306) at the lower end opening of the circular ring (302) enter the square tube (401) through the transport tube. S3, drilling holes, sowing and unlocking: Grab the handle 1 (405) and place the support leg (105) on the ground, then press down the handle 1 (405) to insert the soil-moving plate (406) gathered at the lower end of the square tube (401) into the ground to a certain depth, then keep the handle 1 (405) still, pinch the handle 2 (410) upwards, the handle 2 (410) drives the connecting block (408) to move upwards through the connecting rod (409), the connecting block (408) drives the soil-moving plate (406) to open through the connecting rod 2 (407) to remove the soil and make the soybean seeds in the square tube (401) fall into the hole, then release the handle 1 (405) and the handle 2 (410) to automatically reset; When the square tube (401) moves downward, the rotating rod (503) is rotated through the connecting rod 3 (505), and the rotating rod (503) rotates to drive the push rod (502) abutting against it to move upward, and the push rod (502) drives the L-shaped plate (206) fixedly connected to it to move upward, so that the rack 1 (205) and the gear 1 (204) are separated. After separation, the rack 1 (205) is automatically reset under the action of the reset spring 1 (207). When the square tube (401) is reset, the L-shaped plate (206) and the rack 1 (205) are reset at the same time, and the device can continue to move forward.
