The seed screening barrel is provided with a screening filter plate, a screening hole, a connecting hanging plate, a connecting fixed block and a fixed block groove. The impact screening device includes a driving motor. This new type has the effect of cleaning the dust raised by the screened seeds at the same time; among them, the shortcomings are as follows:

[0004] After research and analysis, it was found that the device uses an eccentric wheel to rotate and impact the screening filter plate to screen the seeds on the screening filter plate. The on-site working noise is loud and affects the staff. At the same time, there is no structure that automatically classifies the screened seeds and imports them into the corresponding separate compartments for storage. This means that even if the seeds are classified and screened, they cannot be conveniently classified and stored. For this reason, we propose an automatic screening and classification device for breeding of good varieties. Utility Model Content
