Abstract
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.
