THRESHING APPARATUS Russian patent published in 2006 - IPC A01F7/00 A01F7/06 A01F12/18 

FIELD: agricultural engineering, in particular, cereal crop threshing equipment.

SUBSTANCE: threshing apparatus has charging and discharge devices, and threshing chamber defined by two axially aligned funnel-shaped surfaces of bodies of revolution. Both funnel-shaped surfaces of bodies of revolution are oriented downward with their larger diameters. One of funnel-shaped surfaces is positioned for performing angular vibrations around single axis by means of vibratory mechanism, is made perforated and is equipped with whips. Other funnel-shaped surface is spring-loaded and positioned for moving along their single axis.

EFFECT: provision for reliable contacting of cereal mass to be threshed with working surfaces of threshing chamber to thereby reduce consumption of power for threshing process.
