Self-locking pin mounting arrangement for conveyor belt cleaner scraper blades

Abstract

A mounting arrangement for removably mounting a conveyor belt cleaner scraping member to a support member. The mounting arrangement includes first and second mounting members adapted to be attached to the support member. Each mounting member includes one or more apertures. A base member is adapted to be attached to the scraping member. The base member includes one or more bores adapted to be aligned with a respective aperture in each mounting member. The bore includes inwardly projecting first and second annular ribs. A mounting pin having a shank is adapted to be inserted into the apertures of the first and second mounting members and into the bore of the base member to thereby connect the base member to the mounting members. The shank of the pin includes a first annular groove adapted to receive and interlock with the first rib of the base member and a second annular groove adapted to receive and interlock with the second annular rib of the base member. The interlocking of the ribs of the base member with the grooves of the mounting pin resists removal of the pin from the bore of the base member while allowing removal of the pin from the bore upon application of sufficient force to the pin.
