Abstract
An auger hopper for transferring cementious material or the like from a supply source such as a cement truck or dump truck to a conveyor belt. A hopper is provided together with a frame for permitting the hopper to straddle and attach to the conveyor. An auger is floatably mounted for rotation within and near the bottom of the hopper. The hopper and conveyor are movably mounted on wheels. Means for mounting at least one of the wheels is provided by which the attitude of at least one wheel mounting means may be varied in relation to the hopper and conveyor. The auger operates to drive cementious materials from the ends of the hopper toward the center and then to discharge the cementious material through a discharge opening at the bottom and onto the conveyor belt without plugging the hopper.
