Description
Technical field
The present invention relates to a kind of top-coal caving face coal separation hydraulic support, especially a kind of hydraulic support that is applicable to that comprehensive mechanization top-coal caving face in mine is mined and discharge refuse carries out simultaneously.
Technical background
For coal production, realize down-hole coal, gangue sorting, make spoil not go out well, be to realize the clean production of coal, green production only way.From the sixties in 20th century, ground coal, gangue sorting technology and equipment are explored always by each coal producer of the world, and gangue is administered and the research of comprehensive utilization, and has obtained great success, but the research of being engaged in down-hole coal, gangue sorting and backfill technology seldom.Along with the mining mechanization degree improve day by day and to the exploitation in dirt band coal seam, the bulk spoil amount of sneaking in the coal increases gradually, reduces the percentage of shale content of raw coal in the down-hole, can improve raw coal quality, reduces the coal separation cost.For this reason, various countries' coal-mining technique all towards pollution-free high-efficient cheaply producer to development.Present screening installation is as using under coal mine, and major defect is to receive that conditions environmental limits under the coal mine, exists problems such as coal separation efficient is low, separating effect is poor, cost of investment is high, service life is short.Therefore, propose coal, gangue sorting method under the new suitable coal mine, developing screening installation safe and reliable, that sorting capability is big, service life is long is the key that realizes the clean production of coal, green production.
Summary of the invention
Technical problem: the objective of the invention is to overcome in the prior art deficiency it, a kind of simple in structure, safe and reliable, top-coal caving face coal separation hydraulic support of reducing the underground hauling of coal cost is provided.
Technical scheme: top-coal caving face coal separation hydraulic support of the present invention; Comprise face guard, front-axle beam, back timber, column, linkage, caving shield; Described caving shield rear end is provided with puts the coal tail boom, puts coal tail boom afterbody and is provided with and puts the cash door, and a side of putting the cash door is provided with that control puts that the cash door opens and closes puts cash door oil cylinder; The bottom of putting the coal tail boom is provided with the vibrating screen panel by Electric Machine Control; The bottom of putting the coal tail boom is provided with the elastic plate of diagonal brace, and the below of elastic plate is provided with back drag conveyor and fortune cash storehouse successively, is provided with dividing plate between drag conveyor and the fortune cash storehouse.
Said front portion of putting the cash door is provided with a curved baffle; The angle of inclination of the elastic plate of said diagonal brace is 30 °～45 °; The width of said elastic plate is slightly larger than the width of putting the coal tail boom.
Beneficial effect: owing to adopted technique scheme, utilize the difference of the physical characteristic consistency and elasticity of coal and spoil, realize that the down-hole raw coal separates.Mining mined realized that the down-hole select while putting, saved fortune coal cost, increased coal mining efficient, reduced the cost of coal separation, realize the clean production of coal, green production.Major advantage has:
1. combine taking and placing top board hydraulic support and can realize anterior coal cutting, coal is put at the rear portion, and the middle part back timber is longer, and the hinged caving shield in anterior hinged front-axle beam rear portion is resisted the fragmentation of coal stubbornly in helping, better realize the sorting of the broken coal cinder of afterbody.
2. put coal plate lower leaf height and will be lower than and put the coal plate, can realize the sorting of bastard coal secondary, elastic plate adopts elasticity material preferably; Bastard coal is separated, owing to be that the sorting bastard coal is a physical property difference of using bastard coal, so sorting does not need consumed energy; More environmental protection and energy conservation; Adopt this device efficiency of separation faster, better effects if does not require the bastard coal size.

The specific embodiment:
Below in conjunction with accompanying drawing one embodiment of the present of invention are done further to describe:
As shown in Figure 1; Top-coal caving face coal separation hydraulic support of the present invention comprises back timber 3, the front-axle beam 2 that links to each other with back timber 3, and front-axle beam 2 front ends are connected with face guard 1; The bottom of front-axle beam 2 is provided with coal-winning machine 9 and front scrapping plate conveyer 10; Back timber 3 belows are provided with front column 11 and rear column 13, and front column 11 is fixed on the base plate 12 with rear column 13 symmetries, and the rear portion of back timber 3 is connected with the caving shield 4 of diagonal brace; Caving shield 4 bottom diagonal braces have the linkage 16 that is fixed on the base plate 12, through the fixing caving coal height of linkage 16 support shield beams 4.Described caving shield 4 rear ends are provided with puts coal tail boom 6; Cash mouth 8 places of putting of putting coal tail boom 6 afterbodys are provided with and put cash door 19; The front portion of putting cash door 19 is provided with a curved baffle 7, and a side of putting cash door 19 is provided with that control puts that cash door 19 opens and closes puts cash door oil cylinder 20, and the bottom of putting coal tail boom 6 is provided with the vibrating screen panel 5 by motor 18 controls; As shown in Figure 2; Drive vibrating screen panel 5 through motor 18 and filter out spoil, because its physical property hardness is different, it is different with the diameter of spoil particle that fragmentation obtains coal when fragmentation for run-of-mine coal (ROM coal).The bottom of putting coal tail boom 6 is provided with the elastic plate 17 of diagonal brace, and the angle of inclination of the elastic plate 17 of diagonal brace is 30 °～45 °; The width of elastic plate 17 is slightly larger than the width of putting coal tail boom 6.The below of elastic plate 17 is provided with back drag conveyor 14 and fortune cash storehouse 15 successively; Back drag conveyor 14 transportation coal cinders; Fortune cash storehouse 15 is below putting cash mouth 8; There is track can transport spoil below, between back drag conveyor 14 and the fortune cash storehouse 15 dividing plate is housed, launch coal cinder far away with prevention and get into fortune cash storehouse to storage cash storehouse.Because the physical property elasticity of bastard coal is different; Bounce-back through elastic plate is apart from difference; Spoil elasticity is bigger, and bump elastic plate and rebounding when coal and spoil mixture are fallen by top, coal launch the nearer drag conveyor behind the fortune coal that falls into; The spoil bounce-back far falls into waste bin, realizes coal and spoil secondary separation.
The course of work and principle: when just adopting, the coal of being adopted is transported through portion's front scrapping plate conveyer 10, after the top coal carries out fragmentation by coal-winning machine 9; Be fixed to certain caving coal height by linkage 16 support shield beams 4 and adjusting, run-of-mine coal (ROM coal) dropped on the vibrating screen panel, open motor 18 and make vibrating screen panel 5 vibrations through putting coal tail boom 6; Motor 18 vibrations run-of-mine coal (ROM coal)s fall coal cinder, and spoil is realized bastard coal primary election through putting cash mouth 8 to fortune cash storehouse 15; Because coal cinder is different with spoil hardness; Broken back coal cinder particle diameter is less, and most of spoil particle diameter is bigger, and coal goes out from vibrating screen panel 5.Contain the granule spoil in the coal body by the screening of vibrating screen panel place, different with spoil elasticity according to coal, coal and granule spoil are fallen elastic plate 17; Because coal elasticity is less, bullet is fallen nearer back drag conveyor 14 and is transported, and spoil elasticity is bigger; Be bound to and transport cash storehouse 15 at a distance, realize the secondary coal separation.
