ABSTRACT:
A trailing arm scraper assembly for a conveyor belt having an arm extending generally in the direction or normal travel of the belt, and a scraper blade mounted at one end of said trailing arm in a home position having a scraping edge forcibly engaging said belt surface. A blade-mounting block at the end of the arm has a stud element releasably mounting said scraper blade for replacement, and affording pivotal movement of said blade about a blade axis substantially parallel to its scraping edge. The scraper blade has resilient abutments to engage the blade-mounting block to yieldingly resist pivotal movement of said blade away from its home position upon encountering an obstruction on the belt surface as it travels past the blade, and to return said blade to its home position upon travel of the obstruction beyond the blade. The abutments allow greater pivotal movement when obstructions are carried by the belt traveling in a direction reverse to its normal travel. The blade is designed to wear away to provide fresh scraping edges conforming to the contour of the belt. A blade is shown with a uniform width for a set distance from the original scraping edge, and narrowing width beyond the set distance, so that excessive wear is indicated by a narrowing of the swath scraped by the blade.
