Abstract
The utility model relates to environment-friendly equipment for a mine, particularly provides a dust-eliminating device used for controlling dust, and particularly relates to a guide dust-eliminating device for a drill hole. The device comprises a dustproof outer shell and a drill rod, wherein, the drill rod penetrates through the dustproof outer shell along the axial direction, a water sprayer is arranged in the dustproof outer shell, and the center of the dustproof outer shell is connected with the drill rod in a sliding and sleeved mode through a sliding sleeve. A plurality of layers of fan rings capable of freely rotating are arranged on the sliding sleeve through bearings, the lower portion of the dustproof outer shell is provided with a slurry outlet, and the front end face of the dustproof outer shell is in a funnel shape and is connected with the drill hole in a sealing manner. Therefore, the dustproof outer shell can slide along the drill rod, the front end of the dustproof outer shell can be inserted into the drill hole and fixed, and a guide function is achieved on the drill rod. The device is dual-purpose, has a dustproof function and the guide function for the drill rod, prevents drill rod slip damage caused by shaking and collision of the drill rod from occurring, reduces maintenance cost, and is beneficial for development of enterprises.
Description
Technical field
The utility model relates to mining environmental protection equipment, especially controls the dirt equipment that goes out of dust, and specifically a kind of drilling guide is to dust suppression device.
Background technology
Exist at present, when hole in the mining area, usually adopt wind-force to get rid of the interior dust of boring, cause the dust in boring directly to be discharged, cause severe contamination to bring serious harm to operating personnel's physical and mental health, also exist simultaneously larger potential safety hazard, the dirt that must go out, traditional dust collecting method that goes out normally arranges annular spraying together in the job location of drilling, and in the return side of distance job location lOm, large spraying is set, although receiving certain effect, still thoroughly dedusting aspect the dirt that goes out.Particularly for coal field, the development end that some atures of coal are crisp, hard, during the bit cutting rib, the pulverized coal particle that produces is thin, amount is large, and after draining into the wind outside the hole, major part swims in air, give the dust lane that goes out difficult, cause return side airborne coal powder content in job location to substantially exceed setting, seriously polluted environment, have larger potential safety hazard.Take hydraulic blow boring to arrange powder as bright, water is combined with powder and is very easily caused the bit freezing phenomenon, affects the drilling efficiency of drilling rod.
Summary of the invention
The purpose of this utility model is the problem that exists for solving prior art, and has designed a kind of drilling guide to dust suppression device, and is simple in structure easy to use, and good dedusting effect.
The technical solution of the utility model is: a kind of drilling guide comprises dustproof encloser and drilling rod to dust suppression device, and drilling rod runs through dustproof encloser vertically, and dustproof encloser inside is provided with fountain head, and the center of described dustproof encloser is slidably socketed by sliding sleeve and drilling rod; By bearing, multilayer fan circle free to rotate is installed on described sliding sleeve; The bottom of described dustproof encloser is provided with grout outlet, and the front end face of dustproof encloser is infundibulate and is connected with borehole sealing.Make dustproof encloser to slide along drilling rod, also fixing in the front end insertion boring with dustproof encloser, drilling rod is formed guide effect.
One end of described sliding sleeve is fixedly connected with the rear end face of dustproof encloser, and sliding sleeve and dustproof encloser are fixed together, and prevents that drilling rod from rocking.
Be provided with annular sleeve and can insert in boring with the boring junction on described dustproof encloser, the axle sleeve outside is provided with wiper of rubber, can guarantee further that the dust in the hole can enter in dustproof encloser, prevents that dust from leaking.
The support rotating bearing of described fan circle is fixed with each other, and each layer fan circle synchronously rotates, and makes the water of spray to be broken up to form vaporific, and forming between each layer links effectively mixes dust with water smoke.
The beneficial effects of the utility model can draw by such scheme: owing to adopting dustproof encloser directly to be connected with boring, can fully the dust that produces in the hole be led in dust arrester, and because drilling rod and dust cover link together by sliding sleeve, sliding sleeve can play the fixedly effect of drilling rod of guiding, is conducive to keep the stable of drilling rod.The utility model dual-use both can play dustproof effect, can also play guide effect to drilling rod, had avoided drill pipe slip to clash into because drilling rod rocks and had damaged, and had reduced maintenance cost, was conducive to the development of enterprise.
This shows, the utility model compared with prior art has substantive distinguishing features and progress, and the beneficial effect of its enforcement is also apparent.
Description of drawings:
Fig. 1 is structural representation of the present utility model;
Wherein, 1 is the drilling rod drive unit, and 2 is drilling rod, and 3 is the fan circle, and 4 is dustproof encloser, and 5 is ore bed, and 6 is sliding sleeve, and 7 is grout outlet, and 8 is fountain head, and 9 is axle sleeve.
The specific embodiment:
In order to understand better the utility model, explain in detail embodiment of the present utility model below in conjunction with accompanying drawing.
The specific embodiment: a kind of drilling guide comprises dustproof encloser 4 and drilling rod 2 to dust suppression device, and drilling rod 2 runs through dustproof encloser 4 vertically, and dustproof encloser 4 inside are provided with fountain head 8, and the center of described dustproof encloser 4 is slidably socketed by sliding sleeve 6 and drilling rod 2; By bearing, multilayer fan circle 3 free to rotate is installed on described sliding sleeve 6; The support rotating bearing of described fan circle 3 is fixed with each other, and each layer fan circle synchronously rotates.The bottom of dustproof encloser 4 is provided with grout outlet 7, and the front end face of dustproof encloser 4 is infundibulate and is connected with borehole sealing.One end of described sliding sleeve 6 is fixedly connected with the rear end face of dustproof encloser 4.Be provided with annular sleeve 9 and can insert in boring with the boring junction on dustproof encloser 4, axle sleeve 9 outsides are provided with wiper of rubber.During use, the dust in boring is directly collected in dustproof encloser 4 by holing, and dust fully is combined rear formation powder slurry by grout outlet 7 discharges with water smoke.When dustproof encloser 4 was fixed on drill hole, inner 6 pairs of drilling rods of sliding sleeve 2 formed alignment restrictions, play certain guide effect, prevent that drilling rod 2 from significantly rocking.
Above-mentioned explanation is not to be to restriction of the present utility model; the utility model also is not limited in above-mentioned giving an example; the variation that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement also should belong to protection domain of the present utility model.
