Abstract
A material transport and self-unloading vehicle having an open top hopper for accommodating bulk material, as animal feeds. A first material conveying auger is located along the bottom of the hopper for moving material toward a side discharge opening in the hopper. A second paddle auger is located above the first auger for moving material rearwardly in the hopper. A side unloading conveyor mounted on the side of the hopper adjacent the side discharge opening operates to receive material moved through the discharge opening by the first auger and move the material laterally of the hopper to a discharge or feeding location. A drive assembly drivably connects a power take-off drive shaft to the first and second augers and unloading conveyor for concurrent operation of the augers and unloading conveyor. The bottom wall of the hopper has a curved section extended contiguously around the leading section of the flights of the first auger and a linear bend or break line located adjacent the leading side of the first auger in a horizontal plane that generally intersects the axis of rotation of the first auger.
