A conveyor belt cleaner is provided having a removable cleaner assembly that may be easily connected and disconnected from an elongate support member. The cleaner assembly includes one or more scraper blades mounted to an angle bar, an interface between the blades and the angle bar, and an interface between the blades and the support member. The blades have bodies that cover or surround the interfaces and reduce the likelihood of debris entering the interfaces and binding the blades to the angle bar and/or the support member. The cleaner further includes a securing mechanism with a pair of clamps for clamping the angle bar against seats of the elongate support. The clamps cause the angle bar to hold a base portion of the blades against the support member which permits the blade base portions to transmit loading from the conveyor belt directly to the support member.
