[0002] Before planting seeds in agriculture, the seeds need to be separated according to their powder properties such as particle size, specific gravity, charge and magnetism. Seed materials of different particle sizes should be separated into various particle size grades using a perforated sieve surface.
[0003] In the existing seed screening device, the seeds are poured into the storage hopper of the screening device, and then the seeds fall onto the screen by gravity. There are several screens in the screening device for screening seeds of different specifications. The seeds are vibrated to different screens by the action of the vibration motor. However, since the size of some seeds is similar to the size of the screen holes in the screen, they will be stuck in the screen holes in the screen. After a long time of screening, a large number of screen holes will be blocked, reducing the screening effect. At the same time, the screens in the screening device are basically fixed on the screening device, and can only screen agricultural seeds of specified sizes and specifications, and the scope of use is relatively narrow.
