Abstract: Apparatus and method that allows a conveyor belt operator to manually adjust a moving conveyor belt pitch around a curve in a confined space such as a tunnel, while also automatically adjusting skew to restore conveyor belt drift. The apparatus includes a rail pair between which a set of trough rollers, and a lower elevated return roller set, are adjustably mounted. The trough roller set is releasably and adjustably secured to brackets that can slide along a respective rail while the return rollers are also releasably coupled to respective sliding brackets on respective rails. Couplings are used to adjustably secure the trough roller set, and return roller set, to respective brackets by either selecting different bracket elevation attachment points and/or by changing couplings' length. A second set of trough rollers can also be slidably/adjustably mounted on the rails with the return rollers being located between the two trough roller sets.

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 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.

Abstract: An impact bed for supporting a conveyor belt in a troughing configuration. 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.

Abstract: Pulley lagging may comprise: a resilient base and a plurality of ceramic tiles embedded therein. Each ceramic tile includes a tile body having a thickness that is less than the thickness of the resilient base and having a plurality of side surfaces extending between first and second broad surfaces thereof and tapering inwardly towards the second broad surface; wherein the first broad surface is larger than the second broad surface. The ceramic tile preferably has intersecting grooves on the first broad surface and a plurality of raised nubs on the second broad surface. Substantially all of the tile body is preferably embedded in the resilient base, whereby the raised nubs extend from the resilient base.

Abstract: A cushion for a scraper blade may comprise: a support plate having one or more members for engaging a support; a mounting plate opposite the support plate having a first end to which a scraper blade is mountable and having a second end remote from the first end; and a resilient cushioning material between and adhering to the support plate and the mounting plate. The cushion may further include one or more springs extending between the support plate and the mounting plate, or the resilient cushioning material surrounding the one or more springs, or the mounting plate having holes filled by the resilient cushioning material, or the second end of the mounting plate being formed to extend towards the support plate, or a combination thereof.

Abstract: A scraper blade for a conveyor may comprise: a blade body having a scraping edge and a base for mounting the scraper blade on a blade mount of a conveyor, wherein the blade body has a plurality of elongated recessed features extending across the rearward side thereof, wherein the elongated recessed features are spaced apart and are generally parallel to the scraping edge. Additionally, the base of the blade body may be affixed to a scraper blade mount having a shape of a “flattened W” defining a groove that has beveled edges to provide clearance for a fillet weld of a scraper blade support bar to which the scraper blade is mountable.
