SCRAPER CONVEYOR Russian patent published in 1994 - IPC

FIELD: coal conveyance equipment. SUBSTANCE: scraper conveyor has linear sections 2 with bottoms 3 and sides 4, insertion chute 5 with sides 6 and intermediate sheets 7. Spacer 8 with horizontal strip 9 is disposed at sheet junctions. Working run 10 is extending above and below spacer 8, which has vertical strip 11 extending along longitudinal axis of horizontal strip (on it). Slots 12 made in lower surfaces of sheet junction areas are adapted to receive horizontal strips 9 of spacer 8, with ends of horizontal strips being disposed between sides 6 of linear sections 2 and insertion chute 5. During operation of conveyor spacer 8 mounted between two adjacent linear sections 2 provides guiding of working run 10 movable above and below spacer 8. When adjacent linear sections 2 bend one relative to the other, working run 10 is rubbed against spacer 8 with its bend areas to prevent wear of linear section ends and insertion chute 5. EFFECT: simplified maintenance and increased service life of conveyor. 3 dwg
