A conveyor belt cleaner mounted on a transverse support member including an arm extending from a mounting bracket and a belt cleaner blade secured on the arm. A positioning arrangement is provided between the arm and the cleaner blade to allow the blade to rotate about the central axis of the arm within predetermined limits in either direction so as to allow the scraping edge of the cleaner blade to align with the surface of the conveyor belt being cleaned. A nut and a resilient washer are provided to secure the blade against a collar. An alternative securement includes a pin-and-slot connection which allows the same rotative action of the blade relative to the arm and having multiple seals against the entrance of dirt into the connection.
A conveyor belt cleaner including an arm having a first end adapted to be connected to a support mounted transverse to the direction of conveyor belt travel and a second end adapted to support a belt cleaner blade;
