Abstract
An apparatus and method are provided for effectively moving and stirring grain in a storage bin. The apparatus comprises a sweep arm, including an auger support shaft and an independently rotatable drive member, that extends between and is supported on a track along the bin sidewall and a pivotal support at the bin center. As the drive member is rotated, a drive wheel thereon moves over the bin track, causing the sweep arm to travel around the bin. The support shaft is rotatable independently of the drive member and extends from the central frame to a location adjacent the bin track. A plurality of spaced stirring augers depend from the laterally extending support shaft, and all except the outermost one are adapted for movement therealong. Rotation of the support shaft in either direction will cause corresponding movement of the movable stirring augers along the sweep arm. The outer auger remains near the outer wall of the bin. Movement of the stirring augers along the sweep arm, and of the sweep arm around the bin will result in an effective grain stirring path.
