ABSTRACT:
A highly portable sand bag hopper has the shape of a cabinet with the front open. The flat, solid top of the cabinet has a loading opening for loading sand into a lower cone. A horizontal sliding door located near the lower, smaller tapered end of the cone opens and closes the lower discharge opening by pulling a spring-loaded lever arm. The upper part of the cone is loaded with sand at a predetermined level to discharge discreet amounts of sand. A seal may be located around the lower opening to sweep sand or debris from the top of the discharge door.
