ABSTRACT:
A bulk material handling accessory such as a conveyor belt cleaner for use in connection with a bulk material handling system. The bulk material handling accessory includes a main frame, a scraping member including an arm and a scraper blade pivotally attached to the main frame, and a damper mechanism coupled at one end to the main frame and at another end to the scraping member. A mounting mechanism is attached to the main frame for providing linear and rotational movement of the main frame and the associated scraping member and damper mechanism. The damper mechanism includes a damper having a piston and a housing having a fluid chamber. The viscosity of the fluid within the fluid chamber is selectively changeable to change the damping characteristics of the damper mechanism to accommodate changes in operating conditions.
