Claim:
A conveyor belt cleaning device comprising: (a) an elongate housing having a hollow interior and an elongated slot in the upper surface thereof communicating with said hollow interior; (b) a T-shaped element movable in relation to said housing and comprising a base element contained within said hollow interior of said housing which is wider than said elongated slot and a scraper blade mounting element secured to said base element and extending through said slot; (c) an elongate scraper element removably attachable to said scraper blade mounting element of said T-shaped element and having an elongated scraping edge adapted to make scraping contact with a surface of a conveyor belt to be cleaned; (d) an elongate flexible pressurized element mounted within said housing on the opposite side of said base element of said T-shaped element from said elongated slot for adjustably applying pressure to said base element of said T-shaped element; wherein said slot, said hollow interior and said T-shaped element are configured to allow said T-shaped element to pivot between the longitudinal edges of said slot to thereby allow said elongated scraping edge to move in a direction both perpendicular to and tangential to the surface of the conveyor belt, wherein said elongate flexible pressurized element comprises an air bladder folded in half and connected at its ends to a manifold which connects to an air intake valve.
