A conveyor belt cleaning device which can handle conveyor belts with damaged areas, mechanical joints, and/or head pulleys with profile spaces causing the conveyor belt to run unevenly, is provided. The scraper blade is attached to a T-shaped element which has pressure applied by an air bladder held within a housing. The T-shaped element moves freely within the housing to permit movement of the scraper blade in a direction tangential to as well as perpendicular to the conveyor belt.
