DEVICE FOR HUSKING GRAIN OF CHAFFY CROPS Russian patent published in 2017 - IPC B02B3/00 

FIELD: agriculture.

SUBSTANCE: device for husking grain contains a feeding hopper with a loading branch, a fan with blades, a husking chamber having exchangeable helical vertical working surfaces made of elastic material, a centrifugal precipitator. A mesh truncated cone is installed in the outlet branch pipe of the fan, the lateral surface of which is made of a metal mesh with holes, the diameter of which is smaller than the diameter of the grains of the processed products. The size of the upper base of the truncated cone is three quarters of the size of the lower base. The height of the truncated cone is equal to two diameters of the base. The upper base of the truncated cone is compressed to 5 mm. At the outlet of the discharge branch with the possibility of changing the distance relative to the side walls of the discharge branch and above the vertical helical surface a freely rotating cylinder of abrasive material is installed.

EFFECT: improved quality of grain husking.
