A conveyor belt support mechanism comprising a plurality of slider bars, each having multiple low friction wear surfaces with one wear surface in sliding engagement with the conveyor belt and an adjustment mechanism to compensate for wear to said wear surface by moving the slide bar closer to the conveyor belt as the wear surface wears, and a vertical support system for positioning said slider bars. When loads such as impact loads are placed on the conveyor belt, the slider bars support the conveyor belt and prevent the belt from sagging and stretching. As one wear surface of a slider bar becomes worn past an acceptable limit, the slider bar may be removed and repositioned so that a new wear surface engages the conveyor belt.

Conveyor belt support mechanism

A tensioning arrangement is provided to position belt cleaner blades relative to conveyor belt, which arrangement includes an inflatable bladder which acts to move a pivotally mounted crank, which, in turn, moves a support shaft, which carries the cleaner blades. Pressurization of the bladder causes it to expand thereby engaging the arm which moves the support shaft to a position at which the cleaner blades engage the belt to be cleaned.

Pneumatically actuated tensioning arrangement for conveyor belt cleaner

A conveyor belt cleaner mounted on a transverse support member including an arm extending from a mounting bracket and a belt cleaner blade secured on the arm. A positioning arrangement is provided between the arm and the cleaner blade to allow the blade to rotate about the central axis of the arm within predetermined limits in either direction so as to allow the scraping edge of the cleaner blade to align with the surface of the conveyor belt being cleaned. A nut and a resilient washer are provided to secure the blade against a collar. An alternative securement includes a pin-and-slot connection which allows the same rotative action of the blade relative to the arm and having multiple seals against the entrance of dirt into the connection.
