GRAIN MIXTURE SEPARATOR Russian patent published in 2011 - IPC A01F12/44 B07B4/00 

FIELD: agriculture.

SUBSTANCE: invention refers to agricultural engineering industry. The grain mixture separator comprises a receiving-loading device, a screw and a separating channel. The upper end of the separating channel is connected to a chamber of light admixtures acceptance with a fan installed in its upper part. The injection nozzle of the fan is communicated to the lower part of the separating channel by means of an air supply channel. There is a throttling gate installed in the air supply channel. There is a device of cleaned grain discharge in the lower part of the separating channel. The screw is installed serially in the receiving-loading device, the separating channel and the device of coarse admixtures discharge. On the screw section, which is installed in the separating channel, there are rigidly fixed elements for grain mixture mixing. Under the screw in the separating channel there is a sieve installed coaxially. Below the sieve there is a deflector.
