between frame head of reloading machine and transfer conveyor tail, angle between elevating conveyor fuselage and horizontal plane is 5 °-15 °, it is provided with the disintegrating machine 3 of broken coal cinder in the front portion of transfer conveyor tail, is provided with elevating conveyor drive mechanism 1 at frame head of reloading machine place.Described conveyer fuselage includes intermediate channel, open slot, pin rail assembly, cable trough assembly, curb pins board component, 1.75 meters of intermediate channel and 1.75 meters of open slots.Intermediate channel and open slot can levels and bending right and left, the pushing and sliding meeting whole drag conveyor are tried to stop people from fighting each other and the irregular requirement of work surface, open slot is uniformly distributed, can check and overhaul bottom scraper chain, cable trough is the cable apparatus for placing of whole drag conveyor, upper strata is the walking cable of coal-winning machine, and the line constructions such as motor cable, hydraulic pressure water pipe and data cable can be placed in understructure space.Curb pins board component plays the device connecting intermediate channel and open slot, has certain fit clearance to meet the level of cell body and the requirement that bends right and left.The scraper chain assembly of described drag conveyor, adjustment chain component and the drive mechanism that resistance chain device is whole drag conveyor, drive the operating even of whole scraper plate through chain wheel assembly structure after power exports, reached movement requirement.Regulate chain component and resistance chain device is the structure prepared to adjust the length of chain and tensioning；Drag conveyor also includes the feed system for the lubrication of whole drag conveyor and hydraulic pressure such as protective cover hydraulic system 10, water system, lubricating system and elevating conveyor hydraulic system, meets sprocket wheel, bearing, sealing member, the isostructural instructions for use of telescopic oil cylinder.Described conveyer telescopic tail is mainly made up of horizontal drive mechanism II, fixing bracket body, movable machine frame, telescopic oil cylinder, chain wheel assembly, hyoplastron assembly, derailleur and tail cylinder shield etc., described movable machine frame is mainly
