Abstract
A sweep auger apparatus is radially disposed within a circular bin for moving a free-flowing granular material across the floor of the bin towards the center of the bin. A motor is connected to the radial inner end of the auger shaft to rotate the auger flighting about its horizontal axis. A drive wheel is connected to the radial outer end of the auger shaft for supporting the outer end of the auger shaft and for revolving the auger around the central vertical axis of the bin. The improved sweep auger includes panels or a tube connected to the backboard of the auger so as to reside beneath the auger flighting, and thereby minimize the amount of granular material left on the floor as the sweep auger revolves around the bin floor. The panels are adjustably mounted to accommodate variations in the level of the bin floor.
