1. A grain cleaning machine comprising a frame, sieve pans movably mounted inside the frame at an angle to the horizon, brush frames with a device for pressing the brushes against the sieves, movably mounted on the guides of the sieve pans, a crank mechanism imparting plane-parallel oscillations to the sieve pans, brush frames which are movably connected by means of rods to one of the ends of double-arm levers having a length up to their axes the axles of which are mounted on the frame of the grain cleaning machine, and the second ends of these double-arm levers are movably connected by means of rods with the sieve frame, having a length up to their axle in this case, the movement of the brush frames in relation to the sieve stands during one cycle of their movement is equal to
2. characterized in that the brushes within the brush frames are installed with a pitch equal to or less than the radius R of the crank of the crank mechanism of the grain cleaning machine, which ensures an increase in productivity due to multiple, repeated cleaning of the sieves during one cycle of movement of the sieve stands by each brush.
