The shape and size of the seeding tray can be adjusted according to different seeds. The function of the seeding tray is to drop a certain number of seeds at fixed points according to a certain position and distance into the field. Traditional UAV seeding trays cannot screen seeds. In order to better sow multiple seeds, a seeding tray structure for an unmanned aerial vehicle is proposed.

Suction holes are penetrated through the circumferential surface of the seeding tray, and the suction holes are uniformly distributed along the circumferential direction of the seeding tray. A connecting shaft extends outward from the center of the fixed tray, and an air suction channel is arranged inside the connecting shaft;

[0004] Although it realizes the rotation of the tray body around the connecting shaft, since the seeds are fixed by the suction holes and only one seed can be transported through the same suction hole, the individual transportation of seeds is realized, and the accuracy in the UAV seeding process is improved;

[0005] However, it does not solve the problem that the existing seeding tray structure is not conducive to conveniently screening large-grained seeds and conveniently performing negative pressure adsorption seeding operations, is not conducive to scraping and inputting large-grained seeds and single-seed seeding of seeds, and affects the convenience of seed screening and input and the convenience of seeding.
