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. Each flexible scraper is resiliently biased in frictional engagement with the curved surface of the conveyor belt by a tension spring. The scraper members are supported in the operative position by upper and lower crossbar support members. In the preferred embodiment, the upper crossbar support member is articulated or segmented. The separate crossbar portions are independently rotatable from a nominal resting position in which the associated scraper member is held in helical engagement with the conveyor belt. The segmented crossbar portions are pivotally mounted onto an axle and are rotatable through an arc of approximately 90.degree., thereby permitting each segmented crossbar portion to move outwardly away from the surface of the conveyor belt to allow passage of a lump, bulge or protrusion, thus avoiding damaging contact between the protruding conveyor belt and the crossbar during a reversing condition.
