Abstract:
An improved sweep auger for removing grain from a circular bin, the auger including a shaft with a radial longitudinal axis and opposite inner and outer ends, flighting extending along the shaft, the flighting having a leading edge and a trailing edge, a backboard extending along the shaft behind the trailing edge of the flighting, a wheel at the outer end of the shaft to support the shaft and auger above the floor, and a drive train for rotating the shaft and auger in a horizontal plane about a vertical axis at the center of the bin, the improvement comprising:a rigid attachment adjustable mounted on the backboard and extending downwardly therefrom to a level below the flighting into close proximity to the bin floor to minimize the grain left behind the flighting; andthe attachment having a curved surface adjacent the floor to prevent catching of the attachment on obstacles on the floor.
