A scraping device for scraping material from a surface to be cleaned, for example the surface (32) of a conveyor (34) includes a support member (24) and a retainer member (56) attached to the support member. The retainer member includes a cavity adapted to receive a pad (120) of resilient elastomeric material having a retarded resilience. A mounting member (100) is located within the cavity of the retainer member. A scraper blade (23) extends through an opening in the retainer member and is attached to the mounting member. The pad enables the mounting member and the scraper blade to pivot about a first edge (106) of the mounting member between a first position and a second position, and to pivot about a second edge (108) of the mounting member between the first position and a third position. The pad (120) biases the scraper blade with retarded resilience to pivot from the second position toward the first position, and from the third position toward the first position. <IMAGE> |
