Abstract
A conveyor belt scraper assembly includes an array of transversely extending, flexible scraper members engaging, in an operative position, a conveyor belt surface to be cleaned. The flexible scraper members are resiliently biased in frictional engagement with the curved surface of the conveyor belt by a tension spring. Each scraper member includes a flexible tension member, a plurality of scraper blades movably coupled to the tension member, and spacer springs yieldably separating the scraper blades. The scraper blades are differently sized relative to each other to impose different static deflections at separate points along the flexible tension member relative to the conveyor belt surface. According to this arrangement, the deflection forces are shifted to the scraper blades along the trailing end of the cable, thereby avoiding a concentration of forces on the leading scraper blade which could lead to premature wear and breakage of the tension member.
