ABSTRACT:
A mounting and support arrangement for conveyor belt cleaners which provides for selective incremental rotation of a cross-shaft on which is carried a plurality of belt cleaner blades suspended from mounting arms. A radial ratchet and pawl arrangement is provided exterior to the housing of the conveyor belt to be cleaned which provides for rotation of the shaft to bias the cleaner blades against the belt until the desired blade pressure is attained. A locking pawl secures the shaft against counter-rotation.
