ABSTRACT:
Apparatus for unloading from the bottom of a silo having a conventional horizontal floor with a central opening characterized by apparatus extending from the pit radially outwardly for removal of the material and at least one radial sweep auger having its interior end within the pit with its outer adapted for powered rotational movement, the auger having a tapered central shaft that is larger adjacent its exterior end than adjacent its interior end such that the flights of auger blade may be uniformly spaced and pick up material along its full length, since each will handle progressively greater quantities of material near the center, for uniform withdrawal from storage. Also disclosed are the details of specific drive means, track clearing means and other equipment in a preferred embodiment.
