Abstract
A scraper device for a belt conveyor has an elongate scraper blade for extending the width of the belt conveyor and carried by a support unit mounted on a supporting framework. The support unit includes an elongate bar engaged at each end in a ring rotatably supported in a slide block resiliently slidable in a U-bracket of the supporting framework. An axial shear pin traverses the slide block and ring to resist relative rotation therebetween until excessive torque is applied to the blade.
