Abstract

The utility model discloses a primary waste rock is broken system in pit, unload hole, scraper conveyor, vibrating feeder, jaw breaker and waste bin including bottom discharge mine car, the end, the bottom discharge mine car with the hole is unloaded through track swing joint in the end, the end is unloaded and is installed scraper conveyor in the hole, scraper conveyor's discharge end extends to the waste bin top, scraper conveyor with the vibrating feeder overlap joint, vibrating feeder's discharge gate with jaw breaker's feed inlet overlap joint, jaw breaker's discharge gate with the waste bin overlap joint. The utility model discloses can realize the broken of primary waste rock in the pit, reduce and transport and promote the link, reduce the mine production cost, optimize waste rock grain diameter class and join in marriage, reduce the dynamic porosity, improve the motion of control overlying rock and slow down the ground subsidence effect, the system is simple, and the practicality is strong.

Description

A kind of primary gangue underground crushing system
Technical field
This utility model relates to coal mine machinery technical field, particularly relates to a kind of primary gangue underground crushing system.
Background technology
Gangue is the garbage produced in coal production and washing process, and every annual emissions is equivalent to the 10%~15% of coal production.The whole nation total burden of gangue has reached 4,500,000,000 t at present, forms hillock more than 1700, takes up an area ha more than 30,000, and just with the speed increment of annual 100000000 t.Gangue is stored up for a long time, takies a large amount of soil, generates H after polluted source, and spontaneous combustion2S、SO2Etc. harmful gas, ecological environment is constituted significant damage.
Waste filling is that primary for down-hole spoil or earth's surface hillock spoil are transported to underground goaf, with filling goaf by gangue, reaches to control movement, slows down the purpose of surface subsidence.Primary immediate stowing of refuse goaf, down-hole can realize gangue not gug, reduces cost of transportation.But existing downhole gangue filling is all to goaf by primary immediate stowing of refuse, primary spoil size grading is unreasonable, and voidage is big, and decrement is big, controls movement, slows down surface subsidence effect poor.
Summary of the invention
For solving above-mentioned problems of the prior art, the utility model proposes a kind of primary gangue underground crushing system, this system can realize the downhole crushed of primary spoil, reduces transhipment and hoist links, reduces mine production costs;Optimize spoil size grading, reduce voidage, improve and control movement and slow down surface subsidence effect;System is simple, practical.
This utility model adopts the following technical scheme that
A kind of primary gangue underground crushing system, hole, drag conveyor, oscillating feeder, jaw crusher and waste bin is unloaded including drop-bottom car, the end, described drop-bottom car is unloaded hole and is flexibly connected by track with the described end, the described end, is provided with drag conveyor in unloading hole, the discharge end of described drag conveyor extends to waste bin top, described drag conveyor overlaps with described oscillating feeder, the discharging opening of described oscillating feeder overlaps with the charging aperture of described jaw crusher, and the discharging opening of described jaw crusher overlaps with described waste bin.
Further, described waste bin top is provided with the anti-drop net preventing personnel from falling.
Further, described waste bin discharging opening is provided with discharging lock, it is simple in controlling storehouse, broken spoil goes out cash amount.
Further, described waste bin is concrete side walls, to reduce the lower slip resistance of broken spoil, it is simple to broken spoil flows out from waste bin.
The Advantageous Effects using as above technical scheme to obtain is:
The down-hole that can realize primary spoil crushes on the spot, the spoil after broken is used for bashing, it is achieved that spoil not gug, decreases transhipment and the hoist links of spoil, reduces mine production costs;Optimize spoil size grading, reduce voidage, improve and control movement and slow down surface subsidence effect;System is simple, practical.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in describing below is only embodiments more of the present utility model, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is a kind of primary gangue underground crushing system schematic diagram.
Description of reference numerals: 1, drop-bottom car, 2, the end unload hole, 3, drag conveyor, 4, oscillating feeder, 5, jaw crusher, 6, waste bin, 7, discharging lock.
Detailed description of the invention
In conjunction with accompanying drawing 1, detailed description of the invention of the present utility model is described further:
A kind of primary gangue underground crushing system, hole 2, drag conveyor 3, oscillating feeder 4, jaw crusher 5 and waste bin 6 is unloaded including drop-bottom car 1, the end, drop-bottom car 1 is unloaded hole 2 and is flexibly connected by track the end of with, the end, is provided with drag conveyor 3 in unloading hole 2, the discharge end of drag conveyor 3 extends to waste bin 6 top, drag conveyor 3 overlaps with oscillating feeder 4, the discharging opening of oscillating feeder 4 overlaps with the charging aperture of jaw crusher 5, and the discharging opening of jaw crusher 5 overlaps with waste bin 6.Waste bin 6 top is provided with the anti-drop net preventing personnel from falling.Waste bin 6 discharging opening is provided with discharging lock 7, it is simple in controlling storehouse, broken spoil goes out cash amount.Waste bin 6 is concrete side walls, to reduce the lower slip resistance of broken spoil, it is simple to broken spoil flows out from waste bin 6.
The shattering process of the primary spoil in down-hole is: the primary spoil in down-hole is transported to the end through drop-bottom car 1 and unloads hole 2, then it is transported to oscillating feeder 4 through drag conveyor 3, primary spoil uniformly continuous is sent into jaw crusher 5 by oscillating feeder 4, primary spoil is stored in waste bin 6 after jaw crusher 5 is broken, the broken spoil being stored in waste bin 6 flows out to mine car through waste bin discharging lock 7, is finally transported to goaf through mine car.
Certainly; only preferred embodiment of the present utility model described above; this utility model is not limited to enumerate above-described embodiment; should be noted that; any those of ordinary skill in the art are under the guidance of this specification; the all equivalents made substitute, obvious variant, within all falling within the essential scope of this specification, and ought to be by protection of the present utility model.
