Description
Technical field
The present invention relates to a kind of top-coal caving face coal separation hydraulic support, be especially a kind ofly applicable to the hydraulic support that mine comprehensive mechanized caving coal working face is mined and discharge refuse carries out simultaneously.
Technical background
For coal production, realizing underground coal, gangue sorting, make waste not discharged from mine, is realize Coal Clean production, 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, the research that gangue is administered and fully utilized, and achieve great success, but the research being engaged in underground coal, gangue sorting and backfill technology is little.Along with the raising day by day of mining mechanization degree and the exploitation to dirt band coal seam, the bulk spoil amount be mixed in coal increases gradually, reduces the percentage of shale content of raw coal, can improve raw coal quality in down-hole, reduces coal separation cost.For this reason, various countries' coal-mining technique all develops at the production mode reform towards pollution-free high-efficient low cost.Current screening installation is as used at underground coal mine, and major defect limits by underground coal mine conditions environmental, there is the problems such as coal separation efficiency is low, separating effect is poor, cost of investment is high, service life is short.Therefore, propose new applicable underground coal mine coal, gangue sorting method, developing safe and reliable, that sorting capability is large, service life is long screening installation is realize the key that Coal Clean is produced, green is produced.
Summary of the invention
Technical problem: the object of the invention is to overcome deficiency in prior art it, the top-coal caving face coal separation hydraulic support that a kind of structure is simple, safe and reliable, reduce 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 coal tail boom, put coal tail boom afterbody to be provided with and to put cash door, the side of putting cash door is provided with and controls to put that cash door opens and closes puts cash door oil cylinder, the bottom of putting coal tail boom is provided with by the vibrating screen panel of Electric Machine Control, the bottom of putting coal tail boom is provided with the elastic plate of diagonal brace, the below of elastic plate is provided with rear drag conveyor and fortune cash storehouse successively, is provided with dividing plate between drag conveyor and fortune cash storehouse.
Described front portion of putting cash door is provided with a curved baffle; The angle of inclination of the elastic plate of described diagonal brace is 30 ° ~ 45 °; The width of described elastic plate is slightly larger than the width putting coal tail boom.
Beneficial effect: owing to have employed technique scheme, utilizes the difference of the physical characteristic consistency and elasticity of coal and spoil, realizes down-hole raw coal and is separated.The choosing of Bian Fang limit, down-hole is achieved to mining coal mining, saves fortune coal cost, add coal mining efficiency, decrease the cost of coal separation, realize Coal Clean production, green production.Major advantage has:
1. combine taking and placing top board hydraulic support and can realize anterior coal cutting, coal is put at rear portion, and middle part back timber is longer, and the hinged caving shield in anterior hinged front-axle beam rear portion, resists the fragmentation of coal stubbornly in being conducive to, and better realizes the sorting of the broken coal cinder of afterbody.
2. putting coal plate lower elastic plate height will lower than putting coal plate, bastard coal secondary sorting can be realized, elastic plate adopts the good material of elasticity, making coal-gangue separation, is the physical property difference applying bastard coal owing to being sorting 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, to the not requirement of bastard coal size.

Detailed description of the invention:
Below in conjunction with accompanying drawing, one embodiment of the present of invention are further described:
As shown in Figure 1, top-coal caving face coal separation hydraulic support of the present invention, the front-axle beam 2 comprise back timber 3, being connected with back timber 3, front-axle beam 2 front end is 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, front column 11 and rear column 13 is provided with below back timber 3, front column 11 and rear column 13 symmetry are fixed on base plate 12, the rear portion of back timber 3 is connected with the caving shield 4 of diagonal brace, caving shield 4 bottom diagonal brace has the linkage 16 be fixed on base plate 12, can fix caving coal height by linkage 16 support shield beam 4.Described caving shield 4 rear end is provided with puts coal tail boom 6, cash mouth 8 place of putting of putting coal tail boom 6 afterbody is provided with and puts cash door 19, the front portion of putting cash door 19 is provided with a curved baffle 7, the side of putting cash door 19 is provided with and controls to put that cash door 19 opens and closes puts cash door oil cylinder 20, the bottom of putting coal tail boom 6 is provided with the vibrating screen panel 5 controlled by motor 18, as shown in Figure 2, vibrating screen panel 5 is driven to filter out spoil by motor 18, run-of-mine coal (ROM coal) is when fragmentation because its physical property hardness is different, and it is different with the diameter of spoil particle that fragmentation obtains 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 putting coal tail boom 6.The below of elastic plate 17 is provided with rear drag conveyor 14 and fortune cash storehouse 15 successively, rear drag conveyor 14 transports coal cinder, fortune cash storehouse 15 is putting below cash mouth 8, there is track can transport spoil to storage cash storehouse below, rear drag conveyor 14 and fortune cash storehouse 15 between one piece of dividing plate is housed, with stop launch coal cinder far away enter fortune cash storehouse.Because the physical property elasticity of bastard coal is different, different by the bounce-back distance of elastic plate, spoil elasticity is larger, clash into elastic plate when coal and spoil mixture are fallen by top and rebound, coal launch more closely fall into fortune coal after drag conveyor, spoil bounce-back far falls into waste bin, realizes coal and spoil secondary separation.
The course of work and principle: when just adopting, by coal-winning machine 9, adopted coal passage front scrapping plate conveyer 10 is transported, after top coal carries out fragmentation, also regulated by linkage 16 support shield beam 4 and be fixed to certain caving coal height, run-of-mine coal (ROM coal) is made to drop on vibrating screen panel by putting coal tail boom 6, opening motor 18 makes vibrating screen panel 5 shake, motor 18 shakes run-of-mine coal (ROM coal), coal cinder is fallen, spoil realizes bastard coal primary election by putting cash mouth 8 to fortune cash storehouse 15, because coal cinder is different with spoil hardness, after broken, coal cinder particle diameter is less, major part spoil particle diameter is larger, coal goes out from vibrating screen panel 5.Containing granule spoil in the coal body sieved by vibrating screen panel, different with spoil elasticity according to coal, coal and granule spoil fall elastic plate 17, because coal elasticity is less, fall to nearer rear drag conveyor 14 and transport, spoil elasticity is larger, be bound to and remotely transport cash storehouse 15, realize secondary coal separation.
