Abstract
A scraper-chain conveyor has a scraper-chain assembly composed of a pair of outboard chains with scapers therebetween. The assembly passes along upper and lower runs and the lower run is enclosed. Each scraper has an upstanding front face and a lower foot face perpendicular thereto. The foot face slides along a floor of the conveyor and a scraping edge between the front and lower faces transfers material in the upper run. To prevent fine material building up in the lower run, the scraper has a further scraping edge formed between the front face and an upper face generally parallel to the lower face. This further scraping edge slides along the base of the lower run.
