A secondary belt cleaner system for cleaning the surface of the return side of an endless conveyor belt. The system includes a plurality of blade devices that are rotatably biased against the return side surface using a respective torsion spring therein. Each blade device includes a head portion formed by a blade support and a replaceable blade tip that is releasably secured to the blade support. The head portion is connected to one end of a blade arm and the other end of the blade arm is coupled to a rotatable shaft inside a housing that is fixedly secured to a support shaft having mounting brackets at each end for mounting the system transversely to the conveyor belt frame. Adjacent blade devices have different blade arm lengths in order to have the blade coverage overlap with no gaps in between. Because these blade arm lengths are different and to maintain each blade tip in contact with the return side surface, the respective torsion springs in adjacent blade devices are pretensioned to different angular amounts.

An apparatus/method for a conveyor belt lifter apparatus that can be manually-configured to accommodate differently-sized conveyor belts of conveyor systems. The apparatus includes a pair of lifts in between which a trough-shaped adjustable conveyor belt support arm is releasably-secured. An adjustable shaft coupler connects the lifts to allow simultaneous activation and movement of both lifts by an operator engaging only one lift. An adjustable base also allows the apparatus to be adjusted for the conveyor system size. These adjustable components comprise segments that can be releasably secured using quick-release pins. The height of the ends of the conveyor belt support arm can also be manually adjusted to eliminate any gap between the conveyor belt and the support arm before lift activation. Each lift comprises a manually-controlled screw jack with an extender formed thereon to allow the lifter apparatus to raise or lower the particular conveyor belt once the lifter apparatus is installed.

Manually-adjustable lifter apparatus for conveyor belts

An apparatus and method for an automatically pivoting return side idler trainer for returning a drifting conveyor belt back to a central position during operation. The trainer includes a non-collinear shaft having ends fixed to the conveyor structure while a non-collinear tube is pivotally mounted to the shaft. A tapered roller element is rotatably mounted to the tube on each side of the pivotal mounting. The shaft and tube include an offset angle that is determined by the taper angle of the tapered roller elements such that when the trainer is installed, the profile of the roller elements form a level surface along the trainer, parallel to the belt return side, regardless if the belt has a straight or cupped profile. A second embodiment uses a non-collinear shaft to which the tapered roller elements are rotatably mounted and whereby the shaft itself is pivotally mounted to an external conveyor structure.
