OPTICAL-ELECTRONIC DEVICE FOR SORTING CROP SEEDS Russian patent published in 2023 - IPC B07B13/00 B07C5/342 

FIELD: sorting equipment.

SUBSTANCE: proposed invention relates to devices for sorting by parameters or properties of sorted products or materials, for example, sorting performed using devices that perceive or measure these parameters or properties, in particular to devices that provide sorting of seeds according to quality characteristics. An optical-electronic device for sorting seeds of agricultural crops contains a sequentially interconnected electric drive for a sectional vibrating feeder, above which there is a grain hopper, a sectional vibrating conveyor with electrodes, a control unit and a drive, an electromagnetic feeding conveyor with electrodes, a control unit and a drive, an electromagnetic feeding drum with electrodes and a control unit located along its inner circumference, light sources and optical units installed above an electromagnetic feeding conveyor and an electromagnetic feeding drum, bins for conditioned, rejected and processed grain. The device contains an additional conveyor installed under a hopper with conditioned grain, above which there is an ozonizer and a nozzle for liquid fertilizer, and a hopper for processed grain. The cells for moving grain on the drum are made of movable arc-shaped elements installed parallel to each other with a gap.

EFFECT: improving the quality of selected quality seeds.
