ABSTRACT:
The device is operative to discharge the triangular ridge of grain, which remains in the bottom of a cylindrical storage bin after the bulk of the bin contents has been discharged by gravity through a central outlet in the bin floor. The device comprises a vertical, rotatable, driven shaft mounted to extend upwardly from the outlet. A free-floating sweep arm is pivotally attached at its inner end to the base of the shaft, so that said arm can rise or fall in a vertical plane. The sweep arm extends outwardly to the wall of the bin. A plurality of parallel, spaced apart, sationary fins protrude downwardly from the undersurface of the sweep arm. The fins are arranged at a trailing angle of about 45.degree., relative to the longitudinal axis of the sweep arm. The forward end of each fin is located on a radius which is equal to or larger than the radius on which the rear end of the next outer fin is located. Thus grain moved inwardly by the outer fin is contacted by the inner fin. The fins progressively increase in depth from the outer end of the sweep arm to its inner end, so that each fin is adapted to move about the same volume of grain, even though each fin moves at a different velocity when the arm is sweeping.
In operation, the fins penetrate by gravity into the grain. The free-floating arm is adapted to constantly conform with the surface of the grain body. The fins thus consistently move a constant volume of the grain inwardly, for discharge through the central outlet.
