THRESHING FACILITY Russian patent published in 2010 - IPC A01F7/00 A01F7/06 A01F12/18 

FIELD: agriculture.

SUBSTANCE: invention refers to agricultural engineering. The threshing facility consists of a threshing chamber and loading and unloading devices. The threshing chamber is formed with funnel-like surfaces of external and perforated internal rotation bodies. The internal rotating body is equipped with bars and an oscillating mechanism of an unbalance type. A spiral of a supplying worm is arranged on the upper end of a vertical driven shaft. The external rotating body is installed on the frame by means of hinges of spring-loaded inclined bracings; also the hinges are connected with the lower part of the external rotating body and with the frame. A roller is arranged on the lower end of the spiral of the supplying worm; the roller contacts internal surface of a mouth of the external rotating body. Dimension from axis of internal rotating body to the utmost remote point of the roller exceeds half of internal diametre of the mouth of the external rotating body in the point of its contact with the roller. Each bracing is equipped with two springs of counter action. At operation axis of roller rotation moves along circumference relative to vertical axis of internal rotating body.

EFFECT: process of relative running-in surface of internal rotating body with surface of external rotating body increases through-put capacity of threshing facility.
