FIELD: mining industry, namely, drilling and loading mining machines, used when driving preparatory mines in mining industry, primarily in coal industry.

SUBSTANCE: loading-transporting tool consists of loading, linear and unloading sections, interconnected jointly. In aforementioned sections, running rollers are mounted, axes of which are perpendicular to planes of aforementioned sections. Two L-shaped scraping conveyors with L-shaped scrapers are closed in circular manner around rollers. Scrapers are connected by vertical section to the chain. Working branches of scraper conveyors are mated with running rollers by sides of chains, provided with horizontal sections of scrapers. Running rollers of idle branches are mounted in supports, which are positioned above scrapers, have height, not exceeding height of scraper, and are in contact with scrapers in zone of vertical parts of the latter. Generating line of running rollers of working branches are positioned at a distance from front edge of loading section, not exceeding 2,5 l, where l - length of horizontal section of scraper.

EFFECT: increased efficiency of transportation of large pieces of rock along the loading/transporting tool.
