AI Technical Summary
The screening efficiency of existing seed screening devices is low, resulting in shriveled seeds mixed in with the final packaged seeds, which affects the sowing success rate.
The design of the inclined screen plate and the guide plate makes the seeds evenly distributed along the surface of the screen plate, extending the movement path of the seeds on the screen plate. The disturbance generated between the screen holes by the turbulence component, combined with the push end to drive the screen plate to shake up and down, forms mechanical vibration, which enhances the screening effect. At the same time, a double-layer screen hole structure is set for graded screening.
It improves the efficiency and accuracy of seed screening, prevents seed accumulation or jamming, extends the service life of the equipment, ensures the residence time of seeds on the sieve plate, and enhances screening smoothness and screening quality.
