US 5,988,360 A · Replacement slider bar adapter assembly

Abstract

A load zone area of a conveyor system which includes a continuous belt which carries bulk materials such as stone, ore, grain, etc. to a discharge point where the material leaves the belt as the belt wraps around a head pulley and returns along the under side of the conveyor system to a tail pulley which brings the belt back to a point which it can be loaded again. The load zone area typically has multiple support rollers closely spaced together to minimize the effect of the material impacting the belt which deflects the belt downward, thus creating a gap between the belt and the skirt seal causing leakage. The existing rollers normally have three rollers which form a "U" shape trough for the belt the two "wing" rollers are removed from the existing troughing roller assembly and replaced by a steel adapter to which a low friction rail may be attached longitudinally to the direction the belt moves, thus reducing the downward deflection of the belt where the material being loaded on to the belt is impacting the belt, and avoiding the gaps between the belt and the skirt seals.

Dependent claims

A slider bar and support for a troughing conveyor system having a continuous belt trained about head and tail pulleys having parallel turning axes, and a series of transverse cross members, said transverse cross members having a length extending across and below the width of said belt, and having an end length underlying each of the marginal edges of said belt,

said support having a base engagingly mating with said transverse cross members, a base connection mounting said base on one of said end lengths, a support plate extending upright from said base, a mounting element for said slider bar, and a mounting connection for mounting said mounting element on said support plate,
said slider bar being adapted to be mounted on said mounting element along the length of the marginal edges of said conveyor belt, said slider bar having a T-slot extending throughout its entire length, and confronting said mounting element, and including a clamping bolt having a head, a shank, and a fastener, said head and shank engaging said T-slot, and said fastener clamping said bar to said mounting element,
at least one of said base connection and said mounting connection being adjustable to afford displacement of said mounting element and said slider bar toward and away from said marginal edges of the belt.
