The invention comprises a grain cleaning apparatus having a frame with a plurality of augers mounted beside one another in parallel relation. Screens surround the augers except at the ends of the augers to allow grain to enter and leave at the ends of the augers. A box like frame encloses the rearward ends of the augers with an open top to allow grain to be be cleaned to be dumped into the open rear ends of the augers. A motor is provided with drive means to rotate the augers simultaneously whereby the augers will auger the grain from the box along the augers within the screens to the forward end of the frame, a chute is provided at the forward end for the grain to leave the frame after traveling along the augers. The mesh of the screens is smaller than the grain so as to retain the grain within the screens as it travels along. The mesh allows foreign particles and chaff smaller than the size of the openings to pass through the openings and drop downward from the screens. A bin is provided beneath the screened augers to collect the smaller particles and another auger is provided in the bin to auger the particles out of the bin.
