TRIPLE-CHAIN SCRAPER CONVEYOR Russian patent published in 2003 - IPC

FIELD: mechanical engineering; materials handling facilities. SUBSTANCE: invention relates to triple-chain conveyors with traction member and it can be used in mining and other industries on conveyors of increased length and capacity. Proposed triple-chain scraper conveyor contains endless traction member closed in vertical plane on end sprockets and resting on guides of panline flight, and three mechanically intercoupled parallel traction chains with fitted-on scrapers which are secured in turn by their on two outer traction chains. Alternating scrapers are freely fitted with clearances between outer traction chains and are secured on inner traction chain by their central part. Scrapers secured on outer traction chains are provided with cavity in middle part to located inner traction chain. Conveyor is furnished with length of round-like chains, some ends of which are coupled with scrapers secured on inner traction chain, and other ends are connected to outer traction chains either directly or through scrapers secured on outer traction chains.
