ABSTRACT:
A grain cleaning attachment is disclosed for a grain auger. The attachment includes a cylindrical vibrating portion to surround the auger flighting after removal of a portion of the auger tube. The vibrating member is sized to provide a clearance between the walls of the member and the auger flighting to permit vibratory displacement of the member. Rubber sleeves connect the vibrating member ends to free ends of the auger tube. A vibration motor is carried by the vibrating member to affect vibration of the member. A tube support member is provided comprising a pair of rigid sleeves rigidly connected to the auger tube on both a downstream and upstream side of the vibrating member. Rigid braces connect the sleeves in axial alignment. A downstream sleeve has an opening to find therethrough in communication with an interior of the tube with a blower carried on the sleeve having an intake in communication with the opening. A bottom portion of the vibrating member is a sieve which separates out small foreign material from grain as grain is carried by the auger through the vibrating member. The foreign material which is too light to be properly separated migrates to a top surface of the grain as the vibrating member vibrates. This material is drawn off through the blower as the grain proceeds its transporation through the auger. Air current through the grain draws the light material out of the grain and through the blower.
