Abstract

The invention provides a Submerged Scraped Conveyor (SSC) arrangement which only makes use of a mining chain 48 attached to a single hinge line on the flight plate assembly 44, and the introduction of a chain guard 46 to guide material in the flight. The flight assembly 44 has a flight bar 60, single in line hinge position over the length 62 of the flight with possibly one wide or multiple narrow hinges over the width 64 of the flight, to ensure stability over the width. The flight assembly 44 has a flight plate 70, side walls 72, a return support pad 74 and water drain holes 76. The flight can freely rotate 68 around this hinge point. The sides of the scraper conveyor are fitted with chain guards 46 to guide material 88 on the flight plates 102 between the two side wall plates 108. These guards 46 further protect 104 the idlers and chain from large particle ingress and assist the main material body being conveyed to remain on the moving deck assembly.
