ABSTRACT:
A nozzleless belt-cleaning sprocket support shaft for cleaning endless conveyor belts has a first end, a second end, a central portion of generally square transverse cross section with a plurality of elongate narrow slits in each of the side walls in longitudinally spaced apart relation along its length, and a plurality of sprockets mounted thereon. Cleaning fluid is simultaneously discharged through the slits in a fan spray pattern onto the inside surface of the conveyor, through crevasses, joints, hinges, interfaces and openings in the belt to effect cleaning of the belt, and between the exterior surfaces of the shaft and interior surfaces of the bores of the sprockets and the bearings that support the shaft to effect cleaning of the overlapping surfaces, during rotation of the belt. The cleaning shaft may be used with various types of conveyor belts and the ends may be mounted in conventional bearings.
