AI Technical Summary
Existing screening equipment for maize breeding can clog the screening screen when maize kernels contain dust and impurities, affecting subsequent screening work.
A screening device for maize breeding was designed, comprising a maize vibrating dust removal table, a dust removal net, a miniature cylinder, a pusher, a catapult ball, an electric telescopic rod, and a cleaning brush. The device removes dust through vibration and mechanical structure, removes dust from maize kernels using the dust removal net, and performs size screening using screening nets with different apertures.
It effectively removes dust and impurities from corn kernels, avoids clogging of the screening screen, and improves the quality and screening efficiency of corn kernels.
