Description of drawings
The structural representation of a kind of drilling dust-proof that Fig. 1 provides for present embodiment;
Fig. 2 is the right side structural representation of drilling dust-proof among Fig. 1;
Fig. 3 is the use view of drilling dust-proof among Fig. 1.
The specific embodiment
The structural representation of a kind of drilling dust-proof 1 that Fig. 1 provides for present embodiment, Fig. 2 is the right side structural representation of drilling dust-proof 1 among Fig. 1, in conjunction with Figure 1 and Figure 2, the utility model provides a kind of drilling dust-proof 1, drilling dust-proof 1 is column structure, the axis direction of drilling dust-proof 1 is provided with to stretch into the through hole 2 of drilling rod, in use drilling rod is extend in the through hole 2 of drilling dust-proof 1.And the end of drilling dust-proof 1 is provided with the water inlet 3 that is connected for extraneous watering.The inwall of drilling dust-proof 1 and outer wall are provided with a plurality of spray orifices, the spray orifice that is arranged on outer wall 11 as shown in FIG. and be arranged on the spray orifice 12 of inwall, spray orifice 11,12 all with water inlet 3 conductings.Each concrete spray orifice 11,12 and the mode of water inlet 3 conductings can be for for example, each spray orifice 11,12 is connected by structures such as conduits with water inlet 3, perhaps be set to hollow structure between the inside and outside wall of drilling dust-proof 1, by pressurizeing at water inlet 3 places, current are flowed between the inside and outside wall of drilling dust-proof 1, thereby spray water by each spray orifice.In use this drilling dust-proof 1 is extend into boring, when drilling, the coal in holing or rock dust dirt particle are washed dedusting by spray orifice.
The drilling dust-proof 1 that present embodiment provides, by this drilling dust-proof 1 is set to column structure, be provided with to stretch into the through hole 2 of drilling rod at its axis direction, and the end is provided with the water inlet that is connected for extraneous watering, and wall and outer wall are provided with a plurality of spray orifices within it, spray orifice all with the water inlet conducting.Present embodiment adopts many group spray orifices, before coal or rock dust dirt particle do not enter the tunnel, carries out spraying firing dust in crag, and convenient operation personnel depositing dust in the process of drilling reduces dust to operating personnel's harm.
Preferred as technique scheme, spray orifice be evenly distribution.As shown in Fig. 1, Fig. 2, each spray orifice 11,12 is arranged on the axial direction of the inwall of drilling dust-proof 1 and outer wall uniformly, also is equally distributed on circumferential direction.Can more thoroughly remove coal or rock dust dirt particle in holing like this.
Preferred as technique scheme, spray orifice is atomization mechanism.Adopt atomized water to carry out adsorption removal to more tiny dust.
Preferred as technique scheme, drilling dust-proof 1 material is metal or plastics, concrete is large such as hardness such as steel, aluminium alloys, engineering plastics, the material of wear resistant corrosion resistant.Consider the vibration that is in of this drilling dust-proof 1, in the operating environment of coal or rock dust dirt abrasion of particles, need selection corrosion-resistant, anti abrasive material, the preferred steel of present embodiment is as the material of drilling dust-proof 1.
Preferred as technique scheme, drilling dust-proof 1 is cylinder.Considering with the shape of holing to be complementary, select cylindrical shape, can certainly be polygonal prism for the cross section, such as six prism structures, eight prism structures etc.
Preferred as technique scheme, when drilling dust-proof 1 was cylinder, it was 0.8 ~ 1m that the exterior contour of drilling dust-proof 1 is of a size of length, diameter is 0.15 ~ 0.25m.The length of drilling dust-proof 1 is too short should not carry out sufficient Adsorption to coal or the rock dust dirt particle in the boring, the long rigidity that reduces again drilling dust-proof 1 integral body, select suitable abundant removal to coal or rock dust dirt particle about 1m, guarantee simultaneously the rigidity of drilling dust-proof 1 integral body.The selection of diameter is complementary with the needs of usually punching, preferably 0.2m.
Fig. 3 is the use view of drilling dust-proof 1 among Fig. 1, as shown in Figure 3, during use, opens a hole in position to be drilled first, for example, and 1 meter of hole depth, 0.2 meter in aperture.Then, drilling dust-proof 1 is stretched in this hole, when drilling, drilling rod passes in the through hole 2 on the drilling dust-proof 1, when coal or rock dust dirt particle are gushed out to drilling dust-proof 1, open the water inlet 2 on the drilling dust-proof 1, after a plurality of spray orifices 11 on the drilling dust-proof 1,12 sprayings, coal or rock dust dirt particle are met water smoke absorption landing, water smoke accumulates current after carrying coal or the landing of rock dust dirt particle, last current carry coal or rock dust dirt particle flows out boring, thereby reach better dust-laying effect.
The drilling dust-proof 1 that present embodiment provides is without any need for power supply or press wind, does not have the quick-fried problem of losing; This device volume is little, and is lightweight, easy to use; This device adopts the inwall outer wall that many group spray orifices are set, before coal or rock dust dirt particle do not enter the tunnel, and the dirt that in advance in crag, goes out, thereby after having avoided coal or rock dust dirt particle to enter the tunnel, the go out difficulty of dirt work of increase.
It should be noted that at last: above each embodiment is not intended to limit only in order to the technical solution of the utility model to be described; Although with reference to aforementioned each embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment puts down in writing, and perhaps some or all of technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the scope of each embodiment technical scheme of the utility model.
