Abstract
A portable sweep auger apparatus and method for controllably transferring predetermined continuous amounts of granular and powdered gypsum from a pile of gypsum to an irrigation ditch. The apparatus includes a base member, a driver member and an auger assembly member mechanically coupled to the driver member. The driver member and the auger assembly member are pivotally coupled to the base member to effect forward travel that depletes the gypsum pile. A first level of control is effected by a fixed auger design that coact with the driver member for regulating and delivering predetermined amounts of the gypsum material. A second level of control is effected by a slip clutch wheel coacting with the rotating auger shaft for controlling forward movement of the entire auger assembly towards and against the pile of gypsum material until the material has been depleted. A track that compensates for unleveled terrain is provided for guiding the slip clutch wheel.
