ABSTRACT:
A plaster spraying and concrete mixing machine comprised of a frame chassis, a rotatable top loading horizontally axis mounted drum type mixing tank with a center mounted rotatable mixing shaft and mixing paddles therein, and a gravity fed Moineau type progressive cavity pump mounted to the bottom of the mixing tank for pivoting therewith. A primary power source and driving mechanisms provide for turning of an air compressor, the mixing paddles, and the Moineau pump which enable the machine to mix and spray plasters and other cementitious materials. The embodiment of a selectively rotatable mixing tank provides that the machine can also mix and conveniently fully discharge batches of concrete or mortar. The pump is mounted directly to the bottom of the tank with the drive arrangement permitting the pump to pivot with the mixing tank between its mixing and dumping positions. One drive arrangement includes a drive member coaxial with the pivotal axis of the tank and another drive arrangement permits disconnecting of the pump to permit it to rotate with the tank.
