Description
Technical field
The utility model relates to a kind of the middle pan of scraper conveyor, specifically a kind of for box two plate the middle pan of scraper conveyor for the drag conveyor gangue refill coal winning technology of down-hole combined mining working rear portion, colliery.
Background technology
The gangue processing produced under coal mine is backfilling into down-hole after processing, and directly is filled in goaf, has both prevented that gangue from going out occupation of land and environment pollution that well brings, eliminated again the goaf geological disaster; Simultaneously, displacing coal resources, solved under the water body, under building, under railway and technical barrier that on karst aquifer, " three next upper " exploit, is to achieve many things at one stroke.
Along with the continuous increase of gangue refill fully-mechanized mining working, for gangue refill, by the reliability of the middle pan of scraper conveyor, also have higher requirement.
At present, in use there are the following problems by the middle pan of scraper conveyor for the gangue refill of the type:
(1) the gangue refill fully-mechanized mining working is owing to being that the loose coal spoil freely is scattered from top to bottom, and dust is larger, and the underground work environment is poor, and Dust Concentration is excessive very easily causes an explosion accident.After adopting support at present, the tail boom position arranges atomizing de-dusting apparatus, and because distance gangue setting point distance is larger, dust-laying effect is not obvious.
(2) gangue refill is distributed in symmetrical position, intermediate channel two ends with the middle pan of scraper conveyor suspension arrangement
Put, leak near the cash mouth factor impacts such as leak cash vibration, closure plate folding impact, quality are laid particular stress on, scraper chain operational shock owing to being subject to, intermediate channel suspension less stable.
(3) gangue refill can't back cover due to functional requirement by the middle pan of scraper conveyor, plate among adding
Open Lou cash mouth, the intermediate channel integral rigidity is poor, yielding.
(4) gangue refill is arranged in intermediate channel along transporting direction by the middle pan of scraper conveyor push cylinder
The left and right sides, fragile near goaf one side cylinder hydralic hose, cylinder piston rod exposes the scratch of easily colliding with, and causes oil cylinder to use, and this goaf, position is deathtrap, and maintenance repair is dangerous.
(5) gangue refill is lamina with the middle pan of scraper conveyor leakage cash mouth closure plate, and intensity is low, the life-span
Short, be out of shape and can't pull open or close up after use a period of time.
Summary of the invention
For above deficiency, the purpose of this utility model is to provide a kind of drag conveyor box two middle plate gangue refill intermediate channel, compared with prior art, it can realize that atomizing de-dusting, intermediate channel hang operation stability, intermediate channel rigidity, push cylinder and sebific duct MP maintenance prevention, closure plate strength problem.
