ABSTRACT:
A hand-held blast cleaning machine having a motor which serves as a handle. The machine includes a blast assembly for propelling abrasive material against a surface and a hopper for supplying abrasive material to the blast assembly. The blast assembly has a blast corridor, a rebound corridor, a blast opening, a blast wheel and a motor. The motor drives the rotation of the blast wheel and serves as a handle. The hopper has a return corridor, a collection area, a feed area and a vacuum conduit. The vacuum conduit is connected to a vacuum source to collect dust and debris from the blast cleaning operation. In one embodiment, an side-blast hopper, a down-blast hopper, an up-blast hopper and a side-feed hopper are all interchangeably attachable to the same blast assembly. A shut-off handle is attached to the blast assembly to provide automatic shut-off abrasive material to the blast wheel and to function as a second handle. In another embodiment, the motor serves as the only handle. A linear actuator connected to a feed valve in the hopper provides automatic shut-off of abrasive material to the blast wheel.
