ABSTRACT:
Apparatus is described for bottom unloading of storage structures (e.g., farm silos and the like). The apparatus includes a pivotable sweep arm which may include either a rotatable auger or an endless chain. Unique ratchet advancement mechanism at the inner end of the sweep arm pivots the sweep arm. A planetary gear mechanism is adapted to transmit rotational energy provided by the power source to the sweep arm. An improved tooth is described for penetrating and dislodging bulk material in a storage structure.
