FIELD: coal mining industry. SUBSTANCE: invention relates to transportation members of coal complexes. Proposed scraper chain includes round-link chain, connecting strips made in form of yoke enclosing horizontal link in cross direction. Ends of yoke are fitted flush in scraper body. Chain is provided also with fasteners for fixing scraper on round-link chain by plain locks made on mated parts of scraper and connecting strip at two sides of round-link chain and closed through mating holes by means of connecting member. The latter is made in form of axle. Mating parts of scraper and connecting strip are made, accordingly, in form of fork grips or shackles. Invention makes it possible to create threadless lock joint and provide long service life, increased strength of scrapers and fasteners on pull chains, sufficient stability of scrapers, possibility of access to idle run of chain without lifting the flight, bringing the section in case of breakage of one of chains from idle lower run to carrying run. EFFECT: improved reliability of chain and convenience in operation. 4 cl, 7 dwg
