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. ^ 2 cl, 2 dwg |
