The traditional agricultural tools have the characteristics of local material, light and handy, multi-purpose and wide applicability. The common agricultural tools include seed selection and screening devices.

[0003] China Patent Network has published an agricultural seed selection and screening device for agricultural technology popularization with publication number CN216163231U. The device aims to solve the technical problem of ineffective removal of impurities in seeds, which affects the screening quality of seeds and the screening efficiency of the device. The device includes a fixed plate, a waste collection assembly fixedly installed on the outside of the fixed plate, a feeding assembly provided at the upper end of the fixed plate, a screening assembly fixedly installed on the outside of the waste collection assembly, and a seed collection assembly fixedly installed at the bottom end of the screening assembly. The device only needs to drop the seeds onto the top of the screening assembly under the action of gravity. The seeds roll down along the screening assembly. The unqualified seeds fall into the guide plate, and the qualified seeds roll into the interior of the seed collection assembly, achieving effective screening of the seeds.
