Removable cartridge cleaner
A removable cartridge cleaner assembly is provided that allows for faster and easier removal of the belt cleaner blades out from under a conveyor belt. In one aspect the assembly includes a biasing surface of one of an elongate support assembly and a channel member configured to be engaged by a securing member and urge distal ends of legs of the channel member into tight engagement with the elongate support assembly and minimize debris accumulation therebetween. In another aspect, the elongate base member and rail member each include lateral portions configured to slidably engage corresponding wedge portions to urge the rail member toward the base member. A method of installing a belt cleaner assembly is also provided which includes camming a rail member downwardly toward the support member upper surface.
