ABSTRACT:
A scraper blade assembly for a conveyor belt cleaner mounted on a conveyor belt system having an endless belt trained about a drum and a rigid support for mounting the belt cleaner. The scraper blade assembly includes a bracket assembly having a pair of parallelly opposed upright plates. A generally L-shaped wiper arm having an arcuate mid-portion is pivotally suspended between the legs. A wiper blade is mounted at one end of the arm and a tension spring is connected between the other end of the arm and the bracket to pivotally urge the arm into scraping contact with the belt. The assembly may also include a stop member at said other end of the arm for limiting the pivotal movement of the arm in one direction to protect the assembly as the blade wears.
