PURPOSE: A scraper in a conveyor belt cleaner is provided to prevent a belt from damaged caused by bending of the scrapper while the conveyer belt moves backward. CONSTITUTION: A cleaner(3) is mounted on a lower side of a head pulley of a belt conveyor. A scraper(4) of the cleaner cleaning a surface of the belt comprises polyurethane material. A lower body is composed as thick to be inserted to a support groove(3b) of a support lever(3a) by forming a support protrusion. A middle body having middle thickness of a curved shape to bend forward and backward by the belt while maintaining elastic strength through forming recessed unit on both lumbar portions. An upper body is thin to scrap dust attached on the surface of the belt by establishing a cemented tip on an upper portion. The scraper composed of cupper removes dust attached on the surface of the belt in operating the conveyor belt. Moreover, the scraper is safely used without damaging the belt by elastic bending of the scraper while the conveyer belt moves backward.
