Abstract:
1. A self-unloading material dispensing device for use in selectively depositing material in a selectively variable target area away from the device, the dispensing device comprising: a container having a front end wall defining an opening, a rear end wall, elongate opposing side walls extending angularly inward toward a longitudinal axis defined by the front and rear walls and a bottom; a rotatable circular auger positioned in the container along the longitudinal axis in substantial alignment with a path of travel of the device for selected movement of material in the container along the longitudinal axis from the container through the opening in the front end wall; a bi-directional continuous loop linear conveyer positioned outside of the container transverse to the longitudinal axis adjacent the opening in the front end wall, the conveyer receiving material passed through the front end wall opening for selected projection of the material in a direction away from a selected one of the side walls of the container to a targeted area for deposit of the material; and a first variable speed power source to drive the auger and a second independent variable speed power source to drive the conveyer for the selected projection of the material to the selectively variable target area.
