AbstractA primary conveyor belt cleaner includes an elongated support extending across but spaced from a conveyor belt of width W and includes a stiff guide extending for approximately the full length of the support; a scraper blade of resilient elastomer resin is mounted on the support and engages the conveyor belt surface. The scraper blade has a short base wall removably mounted on the support by a reinforcement that interfits with the guide; the blade has two longer curved side walls, an inner wall concave toward the belt and an outer wall convex away from the belt. The two side walls come together to form a scraping edge. The belt cleaner includes a torsion bias mechanism that resiliently maintains the belt scraping edge in continuous engagement with the belt. Two or more primary cleaners may be incorporated in one system. Flexure of the blade permits passage of a mechanical splice in the belt without appreciable damage to the blade or the splice.
