Summary of the invention
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provides a kind of and can be close to coal face, the coal mine drilling dust trapping device effectively preventing dust to be blown when holing.
The utility model solves the technical scheme that its technical problem adopts: this coal mine drilling dust trapping device, it is characterized in that: comprise the rigidity cover, dust gathering arrester and the control of dust funnel that are fixedly connected sequentially from top to bottom, the rear end face of rigidity cover is provided with gap shielding unit.
Preferably, described rigidity cover is that left and right, a upper three side sealing closes, the uncovered cuboid shape of rear end face and lower surface, the front end face of rigidity cover has a circular hole boring mouth and can stretch into, have a fixed handle the arranged on left and right sides of the upper/lower terminal of rigidity cover rear end face is projecting respectively, described gap shielding unit is vertically fixed on rear end face border; In rigidity cover, the soffit of upper surface is fixed with one or more connecting pin, and sprayer unit is fixed by connecting pin after the side of rigidity cover penetrates rigidity cover inside.
Preferably, described gap shielding unit is the hairbrush being arranged on rigidity cover rear end face border.
Preferably, described sprayer unit is positioned at the top of described circular hole.
Preferably, described sprayer unit comprises water pipe, high atomization shower nozzle, connector and filter pipe, water pipe open at one end one end is closed, and uncovered one end connects external water source by connector, filter pipe, and the bottom of water pipe is connected with the downward high atomization shower nozzle of one or more injection direction.
Compared with prior art, the beneficial effect that the utility model has is:
1, the rear end face of coal mine drilling dust trapping device rigidity cover of the present utility model is provided with hairbrush, after coal mine drilling dust trapping device is fixedly completed, gap between coal mine drilling dust trapping device and rib can be blocked by hairbrush, coal face can be close to, the coal mine drilling dust trapping device effectively preventing dust to be blown when holing.
2, by arranging sprayer unit, when holing, ejection water smoke, prevents the generation of dust raising phenomenon further.
3, dust gathering arrester is made by the waste and old air duct fabric in down-hole or old canvas and is formed, and achieves the recycling of waste product.
4, first external water source is entering water pipe through filter pipe, after the filtration of filter pipe, decreases impurity content, avoids the blocking of high atomization shower nozzle.

Wherein: 1, connecting pin 2, rigidity cover 3, circular hole 4, fixed handle 5, sprayer unit 6, dust gathering arrester 7, control of dust funnel 8, hairbrush 9, water pipe 10, high atomization shower nozzle 11, connector 12, filter pipe 13, anchor net 14, rib.
Detailed description of the invention
Fig. 1 ~ 4 are most preferred embodiments of the present utility model, are described further below in conjunction with accompanying drawing 1 ~ 4 pair of the utility model.
As shown in Figure 1, coal mine drilling dust trapping device, comprises the rigidity cover 2 of the cuboid shape be fixedly connected sequentially, dust gathering arrester 6 and control of dust funnel 7 from top to bottom, and sprayer unit 5 penetrates rigidity cover 2 from the side of rigidity cover 2 inner, is positioned at the top of rigidity cover 2.
With reference to Fig. 1,2, the rigidity cover 2 be made up of anti-flammability rigid material (as metal sheet) is that left and right, a upper three side sealing closes, the uncovered cuboid shape of rear end face and lower surface.The front end face of rigidity cover 2 has a circular hole 3 boring mouth and can stretch into.There is a fixed handle 4 the arranged on left and right sides of the upper/lower terminal of rigidity cover 2 rear end face is projecting respectively; The border of rigidity cover 2 rear end face is fixed with a circle hairbrush 8 vertical with rear end face.In rigidity cover 2, the soffit arranged on left and right sides of upper surface is respectively fixed with a connecting pin 1, above-mentioned sprayer unit 5 is fixed by connecting pin 1 after the side of rigidity cover 2 penetrates rigidity cover 2 inside, and sprayer unit 5 is positioned at the top of above-mentioned circular hole 3 after fixedly completing.
Dust gathering arrester 6 is soft straight-tube shape, and the air duct fabric waste and old by down-hole or old canvas are made and formed, and achieve the recycling of waste product.The border of the border, upper end of dust gathering arrester 6 and the lower surface of rigidity cover 2 opening is connected and fixed.The border, lower end of dust gathering arrester 6 is fixedly connected with above-mentioned control of dust funnel 7.
As shown in Figure 3, sprayer unit 5 comprises water pipe 9, high atomization shower nozzle 10, connector 11 and filter pipe 12.Water pipe 9 open at one end one end is closed, and uncovered one end is connected with one end of filter pipe 12 by connector 11, and the other end of filter pipe 12 connects external water source.Be connected with one or more high atomization shower nozzle 10 in the bottom of water pipe 9, the injection direction of high atomization shower nozzle 10 is downward.Under mine, external water source to adopt in underworkings static pressure water in supply channel usually, and external water source, through the filtration of filter pipe 12, decreases impurity content, avoids the blocking of high atomization shower nozzle 10.
Specific works process and operating principle as follows: first, boring position of opening is chosen in tunnel, then coal mine drilling dust trapping device is fixed on the anchor net 13 before rib 14 by fixed handle 4, after coal mine drilling dust trapping device fixedly completes, be fixed on the hairbrush 8 of its rigidity cover 2 rear end face border through anchor net 13, and contact with rib 14 surface, the space between coal mine drilling dust trapping device and rib 14 is blocked.
Then connect external water source by filter pipe 12, external water source filter through chimney filter 12, enter water pipe 9 after to be made water fogging ejection by high atomization shower nozzle, and formed in rigidity cover 2 and catch dirt water curtain.Now drill bit starts to hole to rib 14 through after circular hole 3.The airborne dust produced in boring procedure to fall in dust gathering arrester 6 and eventually through control of dust funnel 7 in the effect of catching dirt water curtain, can prevent container from carrying out the collection of dust in the lower end of control of dust funnel 7, because the space between coal mine drilling dust trapping device and rib 14 is blocked by hairbrush 8, dust cannot blow out by the air-flow therefore in tunnel, avoid airborne dust, the liquefaction being more conducive to dust is collected.
The above, it is only preferred embodiment of the present utility model, be not restriction the utility model being made to other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the Equivalent embodiments of equivalent variations.But everyly do not depart from technical solutions of the utility model content, any simple modification, equivalent variations and the remodeling done above embodiment according to technical spirit of the present utility model, still belong to the protection domain of technical solutions of the utility model.
