<p>A grain storage bin has a floor with a central discharge opening, an elongated sweep auger extending radially from the discharge opening toward the wall of the bin, and an elongated shield extending alongside the auger. The sweep auger and shield travel as a unit around the interior of the bin to channel grain toward the discharge opening as the auger is being rotated about its axis. An elongated torque arm attached alongside the shield provides torsional reinforcing for the shield and longitudinal reinforcing for preventing the auger and shield from sagging mid-span.</p> |
