ABSTRACT:
A hopper device for mounting transversely across the material discharge end of a vehicle mounted dump bed adapted to contain particulate material to be spread over a roadway being travelled by the vehicle. This type of hopper includes fixed first and second spaced end walls, a fixed back wall between the end walls and an elongated auger extending between the end walls, and an arrangement for rotating the auger about an axis to move material through the hopper toward one end of the hopper. The hopper includes a cover member extending between the end walls and movable between a spreading position where the material can dump into the hopper and be spread from the hopper, a dumping position where the material can be dumped over the hopper and a cleaning position where access is possible to the auger for cleaning by a water hose. The cover member is mounted on links that coact with the end plates to hold the cover plate in each of the three independent positions without losing control of the movement of the cover member between these positions.
