ABSTRACT:
A conveyor belt scraping apparatus includes a pair of scraper blades connected to a pivoting mounting member. The upstream blade is oriented so as to engage the belt at substantially a 50.degree. angle while the downstream blade is oriented substantially perpendicular to the belt. The scraping pressure applied to each blade is controlled by a pair of actuator cylinders connected between a rigid frame and the pivotal blade mounting member. By extending or retracting piston rods of the cylinders, pressure on one blade is increased while pressure on the other blade is reduced. The blade scraping pressure is adjusted in this manner to provide the best scraping action. The apparatus also includes a mechanical back-up system to provide scraping pressure to the blades in the event the actuator cylinders fail. Further, the apparatus includes a switch that is connected to the conveyor controller. When the conveyor controller is operated to run the conveyor in reverse, the switch closes causing the scraper blades to be pivoted free of and fully disengaged from the conveyor belt. In this way damage to the blades from roll back is avoided.
