The invention provides a threshing equipment (4) for evenly and fluently providing a treatment object to a sway sorting unit (32) and out-dust port (26) to prevent separation grade from reducing. In the said threshing equipment (4), in order to convey the treatment object from the out-dust port (26) of a roller chamber (17) to one side of the said convey chain (20) a revolving drum (36) with helical blade rotating along the axes (P2) perpendicular to the treatment object conveyig direction is mounted. A guide parts (121) with open end is installed above the revolving drum (36) or a screening parts (122) is mounted on the sway sorting unit (32) and extends fron sway sorting unit to the inferior of the revolving drum (36).
