GRAIN MIXTURE SEPARATOR Russian patent published in 2019 - IPC B07B4/02 

FIELD: agriculture.

SUBSTANCE: invention relates to devices for cleaning grain. Grain mixture separator contains receiving-loading device connected through a window with a separating channel. Upper part of the separation channel is connected to the camera receiving light impurities with a fan. There is a device of cleaned grain discharge and multiple belt auger in the lower part of the separating channel. Working surface of the multiple belt auger is made with framed bristle elements of elastic material for contact with the inner surface of the sieve, coaxially placed under the section of the multiple belt ribbon auger. Cross-sectional area of the lower part of the separation channel is larger than the cross-sectional area of its upper part. Multiple belt auger is sequentially located in the separating channel and the output device of large impurities. Shaft-turners are radially fixed on the shaft of a multiple belt auger. Part of the tape auger, located in the output device of large impurities, is placed in a cylindrical sieve. Cylindrical sieve rests on rollers, one of which is connected with a mechanical drive. Cleaning device is fixed at the inner surface of the device for the removal of large impurities with the possibility of contact with a cylindrical sieve.

EFFECT: separator provides for increased efficiency of grain mixture cleaning.
