ABSTRACT:
A conveyor belt fluid nozzle system includes apparatus for directing pressurized fluid such as air across the width of the conveyor belt to remove debris from the belt surface or from objects on the belt. The source of pressurized fluid such as an air compressor is attached to a plenum member. At least one elongated nozzle extends along the length of the plenum member substantially across the width of the conveyor belt. Auxiliary nozzles may be positioned on each side of the belt. The orifice of the nozzle member has a pair of resiliently biased blades that are adjustable to control the flow of the pressurized fluid.
