ABSTRACT:
Disclosed herein is an invention having to do with a method and apparatus for supporting and tensioning cleaning blades that are in contact with a moving conveyor belt. The method and apparatus disclosed herein comprise locating an elongate support bar under the return side of a conveyor belt and positioning its length transverse to the direction of travel of the conveyor belt. The support bar has mounted spatially along its length several individual spring loaded piston-cylinder assemblies. Support plates are connected to the extensible end of each piston-cylinder assembly and cleaner blades are removably attached to the support plates. Each piston/cylinder assembly has an adjustable spring tensioning adjustment for the proper tensioning of each blade. The cleaner blades and piston-cylinder assemblies are arranged adjacently with one another along the length of the support bar, and the blade assemblies have side edges preferably with tongue and groove connections so that each adjacent cleaning blade has a sliding engagement with one another. On each end of the transverse support bar is located a pneumatic/hydraulic, extension/retraction mechanism that connects between the transverse support bar and a support bracket for firmly anchoring the scraper blade assembly to a foundation. The invention contemplates the method of locating the scraper blade assembly on a foundation so that the scraper blade edges are located approximately 1/4 to 1/2 inch below the return side of the conveyor belt.
