Abstract
The utility model discloses a novel dustproof device for coal bed drilling, comprising a dustproof cover and a spray head, wherein, a perforated hole for the drilling rod of a driller is arranged on the dustproof cover; the wall of the dustproof cover is perforated by the jet opening of the spray head; two sewage outfalls are arranged oppositely on the wall of the dustproof cover and the jet opening of the spray head, and a retaining valve is arranged at each sewage outfall. When a soft coal bed is drilled, the dustproof cover is covered on the to-be-drilled part, the drilling rod of the driller is put through the perforated hole for the drilling rod of the driller and is matched in a movable way with the dustproof cover in the circumferential direction; the coal dust formed in the drilling course flies into the dustproof cover from the side of the drilling rod; a dust removing medium is jetted into the dustproof cover through the spray head and sprayed to the coal dust. The utility model has simple structure and convenience for assembly, not only preventing the coal dust from diffusing fast to the mining roadway, but also humidifying the dust coal.
Description
Technical field
The utility model relates to the colliery dust guard, particularly a kind of novel coal bed drilling dust guard.
Background technology
In the coal mining, need soft seam is carried out depth boring with the gas in the discharging coal seam, ensure job safety.During boring, press wind by the duct of establishing in the drilling rod to the depths, coal seam, the gas of depths, coal seam and coal dust are drained outside all side direction of drilling rod coal seam with wind-force, and coal dust is full of coal road and not only environment is caused severe contamination, and operating personnel's health in serious harm.The coal dust that prior art produces for boring generally sprays by shower is installed in the tunnel, and the defective of the method is: water consumption is huge, and spray equipment is installed inconvenience, and the coverage of spray is narrow, is prone to spray the dead angle.
The utility model content
In view of this, the utility model provides a kind of novel coal bed drilling dust guard, prevents that coal dust from carrying out humidifying to coal dust rapid diffusion the time and handling from boring, realizes uniting two into one of dustproof and the dirt that disappears, and is simultaneously simple in structure, easy for installation.
Novel coal bed drilling dust guard of the present utility model comprises dust cover and nozzle, described dust cover is provided with the borer drill rod through hole vertically, the ejiction opening of described nozzle runs through the dust cover wall, is relatively set with sewage draining exit with the nozzle ejiction opening on the dust cover wall, and described sewage draining exit is provided with one way valve.
Further, described one way valve comprises valve plate and compression spring, and described valve plate is along the sewage draining exit horizontally set, and an end and the dust cover of valve plate are hinged, and the other end is connected with the dust cover inwall by the compression spring, and described compression spring applies valve plate and draws pretightning force;
Further, described borer drill rod through hole is provided with axle sleeve, and borer drill rod is rotatably assorted at circumferencial direction by axle sleeve and dust cover.
The beneficial effects of the utility model: novel coal bed drilling dust guard of the present utility model comprises dust cover and nozzle, described dust cover is provided with the borer drill rod through hole vertically, the ejiction opening of described nozzle runs through the dust cover wall, be relatively set with sewage draining exit with the nozzle ejiction opening on the dust cover wall, described sewage draining exit is provided with one way valve, when soft seam is holed, dust cover covers in position to be holed, borer drill rod is penetrated by the borer drill rod through hole and is rotatably assorted at circumferencial direction with dust cover, the coal dust that boring produces enters in the dust cover from all sides of drilling rod, the dedusting medium enters in the cover body and to coal dust by nozzle and sprays, and the dirt mud that spray produces is discharged from sewage draining exit; This device not only can prevent coal dust rapid diffusion in the exploitation tunnel, also can carry out synchronously humidifying processing to coal dust, realizes uniting two into one of dustproof and the dirt that disappears, and is simultaneously simple in structure, easy for installation.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the utility model user mode figure;
Fig. 3 is the enlarged drawing of A portion among Fig. 1.
The specific embodiment
Fig. 1 is a structural representation of the present utility model; Fig. 2 is the utility model user mode figure; Fig. 3 is the enlarged drawing of A portion among Fig. 1.
As shown in the figure:
The novel coal bed drilling dust guard of present embodiment, comprise dust cover 1 and nozzle 2, described dust cover is provided with borer drill rod through hole 3 vertically, the ejiction opening of nozzle 2 runs through the dust cover wall, be relatively set with sewage draining exit 4 with the nozzle ejiction opening on the dust cover wall, sewage draining exit 4 is provided with one way valve, during use, dust cover is covered in the coal seam outer wall, borer drill rod passes dust cover by the cover top to a cover mouthful direction, the gas that boring produces and coal dust spread around the drilling rod and are enclosed in the dust cover startup dedusting media transport system, nozzle ejection dedusting medium, coal dust is promptly formed dirt mud by the absorption of dedusting medium, in the present embodiment, the dedusting medium can be water, also can be foam medium.
As to further improvement of this embodiment, described one way valve comprises valve plate 51 and compression spring 52, valve plate 51 is along the sewage draining exit horizontally set, one end of valve plate and dust cover are hinged by jointed shaft 7, the other end is connected with the dust cover inwall by compression spring 52, and the compression spring applies valve plate and draws pretightning force; When soft seam is holed, gas and coal dust enter dust cover, because of valve plate is closed, sewage draining exit is by shutoff, coal dust can't be escaped from dust cover, so can be by abundant humidifying under dedusting medium spray, along with the gas discharge capacity increases, the dust cover internal pressure increases and valve plate is opened, and gas discharges from sewage draining exit, simultaneously, dirt mud is discharged in the lump, and the dust cover internal pressure reduces, and valve plate is closed again under the compression spring action, under the situation that dustproof and dedusting are carried out synchronously, improve the utilization rate of efficiency of dust collection and dedusting medium.
As to further improvement of this embodiment, the borer drill rod through hole is provided with axle sleeve 6, and borer drill rod is rotatably assorted at circumferencial direction by axle sleeve 6 and dust cover, and axle sleeve structure can reduce beating of drilling rod, prevents drill rod abrasion.
Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
