Abstract
The sweep auger apparatus is radially mounted within a circular bin for storing granular free flowing material and is horizontally rotatable across the bin floor about a vertical axis located centrally of the bin to remove from the bin floor, during each horizontal rotation thereof, a uniform depth of material. The sweep auger is of a constant diameter and uniform pitch and is positioned within a housing structure of a generally right angle shape in transverse cross section that has an upright leg located adjacent the rear side of the auger and a generally horizontal leg arranged adjacent the top side of the auger and projected forwardly from the front side of the auger. The depth of material to be removed is dependent on the angle of repose or flow of the material relative to a horizontal plane. The front edge of the horizontal leg is vertically disposed and spaced forwardly of the auger front side such that the auger, during each horizontal rotation across the bin floor, is capable of removing all material flowing thereto from below the horizontal leg.
