FIELD: machine building.
SUBSTANCE: scraper conveyor comprises closed endless draw actuator to rest on guides of fluted conveyor pan (1) consisting of three parallel draw chains, two outer chains (2, 3) and one inner chain (4). Scrapers (5) are secured in turns to outer chains while scrapers (6) alternating with the former are arranged with clearance between outer chains and secured at inner chains. Spacing between scrapers secured to outer chain and spacers at inner chain secured there ahead in direction of load-carrying flight is taken to be two times larger than that between inner chain scarpers and those at outer chains located there ahead.
EFFECT: higher efficiency of conveyor.
