Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: An apparatus and method for adjusting the trough angle of a conveyor belt transport mechanism and for automatically correcting for conveyor belt creep along the conveyor belt sides during belt operation. The apparatus and method are directed to an idler assembly that pivots through a high point over a base frame. The idler assembly includes a horizontal base strut and angled wing struts on each side of the base strut. Rotatably mounted on the horizontal base strut are a pair of parallel centered rollers that surround a centrally-located pivot point. Rotatably mounted on each angled wing strut is a respective conical-shaped wing roller wherein a lower end of the wing roller remains at a fixed distance from the wing element whereas the distance between the upper end and the angled wing strut is adjustable via a threaded rod using jam nuts to releasably secure the angled wing rollers at a desired angle.

Abstract: A side wall and cover system for conveyor assemblies for containing particulates during conveyor operation. The invention utilizes rollers that are centrally positioned on corresponding support members which support a pair of angled wings the roller sides. These angled wings support impact bars that are aligned in the direction of conveyor movement and support a troughed conveyor belt. Side walls are secured to the angled wings and include an upper surface to which a cover is releasably secured. Seals and gaskets are positioned between confronting surfaces of these components to prevent dust particulates from emanating between the surfaces. The side walls permit additional conveying volume at the sides of the conveyor and a roller hanger is also provided to facilitate the servicing of such rollers without the need to lift the conveyor belt. Plural side wall/cover systems can be releasably secured together using side wall-projecting flanges and interlocking tabs.

Abstract: A V-plow belt cleaner has a cleaning element providing first and second opposing cleaning edges which can be flipped over so that the second cleaning edge is adjacent the conveyor belt; and reconnecting the V-plow belt cleaner to its mount. The flip-able V-plow belt cleaner may comprise: left and right arms defining an apex and providing a mounting interface for cleaning media; a front arm holder attached proximate the apex; a rear support bar attached proximate rearward ends of the arms for maintaining a spacing; one or more rear arm holders attached to the rear support bar; and two or more power arms for connecting to a V-plow mount, each power arm being pivotably connected to a front or rear arm holder and being mountable to positions both above and below the V-plow cleaner.

The impact bed has a plurality of resilient impact bars running lengthwise in a travel direction of the conveyor belt. The plurality of resilient impact bars includes at least a first resilient impact bar having a planar orientation, a second resilient impact bar having a troughing angled orientation and a third resilient impact bar between the first resilient impact bar and second resilient impact bar. The third resilient impact bar has an intermediate angled orientation that is greater than the planar orientation of the first resilient impact bar and less than the troughing angled orientation of the second resilient impact bar. The third resilient impact bar is removable from the impact bed without removing the first resilient impact bar or second resilient impact bar from the impact bed.
