CONVEYOR TROUGH FOR SCRAPER CHAIN CONVEYOR USED TOGETHER WITH COAL MINING MACHINE IN SHAFT

摘要

A conveyor trough (1) for use with a mining machine comprises a pair of side members (2) and a web (3) interconnecting the side members intermediate their edges. Inwardly projecting flanges are formed at the edges of each side member. Each side member is also formed with an outwardly opening preferably V- shaped recess (4), which extends to near the level of the inward flanges and an outwardly projecting ground engaging flange, which merges with that portion of the side member which bounds the lower part of recess (4). The ground engaging flange on the working side of the trough (1) forms a machine track, whilst that on the goaf side supports the rack of the mining machine. Each ground engaging flange is formed to support the lower inward flanges above the ground. A series of troughs can be connected by connecting means engaging in recesses (4). IMAGE
