  • Patent number: 6321901
    Abstract: A conveyor belt cleaner and tensioner assembly including a conveyor belt cleaner and a conveyor belt cleaner tensioner. The conveyor belt cleaner includes a scraper blade assembly having a mounting member and a scraper blade. The mounting member includes a base member adapted to be attached to a cross shaft and first and second flanges extending outwardly from the base member forming a first slot therebetween. The scraper blade includes a mounting base having a bore through which the mounting member extends, second and third slots adapted to receive the first and second flanges of the mounting member, and a third flange adapted to be inserted in the first slot of the mounting member such that the scraper blade is rotatably attached to the mounting member. The tensioner includes a support arm rotatably attached to a rotatable tensioning rod and a pivot arm pivotally attached to the support arm which receives the cross shaft. A biasing member extends between the support arm and the pivot arm.
