Description

Seed screening equipment for agricultural production Technical Field The utility model relates to the technical field of seed screening, in particular to seed screening equipment for agricultural production. Background Seed screening apparatuses used in agricultural production are various, and they select qualified and excellent seeds by utilizing differences in shape, size, specific gravity, surface characteristics, aerodynamic characteristics, and the like of seeds and impurities. CN222369312U, which provides a seed screening device, through setting up driving component, screening component and collecting component, the driving component cooperates with the screening component, the motor in the driving screening component drives to generate centrifugal force to throw out stones and bad seeds, the stones are thrown out downwards from the leak holes a of the cone a through centrifugal force, and bad seeds with lighter specific gravity are thrown out upwards from the leak holes b in the cone b with the rotation radius smaller than that of the cone a and larger than that of the cone b through water buoyancy, after screening, the screened stones are collected and cleaned timely through the collecting component.
