Efficient grain drying and screening device

Abstract

The invention discloses an efficient grain drying and screening device which comprises a shell. Supporting legs are arranged at the bottom of the shell in a bilateral symmetry mode, and a feeing portis formed in the top of the shell; a flow guiding cone is arranged at the inner top end of the shell and is of a cone-shaped shell structure, and ventilating holes are uniformly formed in the side surface of the flow guiding cone; a draught fan is arranged on the right side of the top end of the shell and penetrates through the middle of the feeding port through an air pipe and communicates with the top end of the flow guiding cone; a machine cabin is arranged at the bottom end of the flow guiding cone, and a vertical rotary shaft vertically penetrates through the middle of the machine cabin;and the upper side and the lower side of the vertical rotary shaft are sleeved with fixing bearings arranged at the top and the bottom of the machine cabin. According to the efficient grain drying andscreening device provided by the invention, the structure is novel, structural arrangement is compact and reasonable, a drying mechanism is ingeniously arranged, grain heating is uniform, and the drying efficiency is high; and additionally, a screening mechanism is ingeniously arranged, secondary screening is achieved, and screening is more thorough.
