Scraper chain conveyor for underground workings

A scraper-chain conveyor comprises a series of pans joined end-to-end and a scraper-chain assembly circulated along the pans in upper and lower runs. Each of the pans is sub-divided into upper and lower sections of especially reinforced construction. The upper section of each pan is composed of shaped side pieces connected by a floor plate while the lower section is composed of smaller side pieces connected to a base plate. The side pieces of both the upper and lower sections combine to form sigma-shaped profiles with upper and lower flanges and inwardly-extending V-shaped intermediate portions. The lower section is built up vertically with side structures overlapping the side pieces of the upper section and bolted connections are established between the side structures and the upper section and with lateral accessories, such as barrier plates and guides. The side pieces of the upper and lower sections define lateral guide passages for the scraper-chain assembly and the guide passages for the lower run of the assembly are defined by both the side pieces of the upper and lower sections.

Chain flight conveyor

A scraper-chain conveyor has a scraper assembly and plurality of channel sections defining upper and lower runs for the scraper assembly. The scraper assembly passes round sprocket drums positioned at the ends of the conveyor, and is constituted by two drive chains and a plurality of scrapers connected thereto. The conveyor has first and second straight portions joined by a curved portion. The upper run of the curved conveyor portion is at a lower level than the upper run of the adjacent end of the first straight conveyor portion. The scraper assembly passes between the upper runs of said end of the first straight conveyor portion and the curved conveyor portion via upper and lower deflector rollers which direct the scraper assembly in a Z-shaped path. The upper deflector roller is provided with a drive, whereby the chain tension of the scraper assembly is negligible when the assembly passes round the curved portion.
