It reduces the probability of seeds being eaten, thereby improving the sowing effect.
[0014] 2. This utility model achieves the effect of stirring inside the storage box by setting a stirring shaft, stirring blades and stirring motor, so as to solve the problem that the seed movement rate of the existing storage box is relatively low and the seeds are easy to squeeze to the top of the feeding pipe, causing the feeding pipe to be blocked.

Pneumatic rotary cylinders 19 are installed on both sides of the extrusion tube 5. A rotating seat 20 is installed on the output shaft of the pneumatic rotary cylinder 19. The rotating seat 20 is connected to the top of the insert plate 18 through the pull rod 16, so that the insert plate 18 can be rotated by the pneumatic rotary cylinder 19. An air suction branch pipe 8 is installed on one side of the air suction seeding tray 6. An air suction pump 2 is installed on the top of the mobile host 1. The input end of the air suction pump 2 is connected to the air suction branch pipe 8 through the air suction pipe 9. A mobile frame 7 is installed on the outer surface of the extrusion tube 5.

[0026] The working principle of a precision seeder based on Embodiment 1 is as follows: After the present invention is installed, the moving host 1 drives the storage box 4 to move, and at the same time, the air pump 2 and the air suction seed dispensing disc 6 drive the seeds inside the storage box 4 to move downwards. The seeds are then transported to the extrusion pipe 5 through the discharge pipe 12. Simultaneously, the extrusion motor 21 is started, which drives the cam 22 to rotate. The cam 22 drives the slide rod 13 to move downwards, which in turn drives the extrusion pipe 5 to move downwards. The extrusion pipe 5 then drives the insertion plate 18 to move downwards, thereby planting the seeds in the tilled land. After completion, the pneumatic rotary cylinder 19 is started, which drives the rotating seat 20 to rotate, thereby driving the pull rod 16 to rotate, which in turn drives the insertion plate 18 to rotate, thereby dispensing the seeds into the holes and planting the seeds. Thus, the working process of the equipment is completed.
