Abstract
The utility model discloses a drilling dust removing device, comprising a drilling machine, a wet-type drill pipe and a drill bit. A water ejection guide head enabling water flow in the wet-type drill pipe to be ejected reversely is disposed between the wet-type drill pipe and the drill bit; the inside of the water ejection guide head is provided with a flow concentrating groove communicated with a water guide duct and a plurality of water distributing ducts communicated with the flow concentrating groove; the water distributing ducts are shaped as parabolas; and water outlets of the water distributing ducts are distributed on an outer edge of one end of the water ejection guide head uniformly. Through the water ejection guide head, the drilling dust removing device enables water flow to be ejected along the direction opposite to the direction of the water flow in the wet-type drill pipe, prevents blockage of the water outlets effectively, guarantees smooth progress of drilling work, and prolongs the service lifetime of the drill pipe.
Description
Technical field
The utility model relates to a kind of dust arrester of drilling that is used for mine, building, rock etc.
Background technology
At present, known burrowing device generally has two kinds, and a kind of is the dry type burrowing device, and another kind is the wet type burrowing device.The dust collection method of dry type burrowing device is outside through the dedusting of artificial water spray in boring mostly, and the dust that the method produces is many and dust removing effects is relatively poor; The wet type burrowing device generally is in the middle of drilling rod, to leave water guide duct (being called the wet type drilling rod); And set out the mouth of a river, and though being converted into mud with dust, the method flows out, drilling rod regular meeting damages because of stressed the concentrating in delivery port place; And the delivery port place is very easily stopped up by mud, influences dust removing effects.
The utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of dust arrester of drilling.
Its technical solution is:
A kind of dust arrester of drilling; Comprise rig, wet type drilling rod and drill bit; Between wet type drilling rod and drill bit, be provided with and make the fountain head of leading that current oppositely spray in the wet type drilling rod; The said set inside of leading fountain head have with the wet type drilling rod in the conflux groove that is connected of water guide duct and a plurality of tapping holes road that is connected with the conflux groove, the tapping hole road is parabola shaped, and the delivery port in tapping hole road evenly distributes at an end outer rim place that leads fountain head.
Further, the above-mentioned dust arrester of drilling also comprises high-pressure water, and high-pressure water is connected with the water inlet of rig through aqueduct.
The useful technique effect of the utility model is:
The utility model is led fountain head through setting up one, makes the direction ejection that current are opposite in current edge and the wet type drilling rod, prevents that effectively delivery port from stopping up and guarantee carrying out smoothly of boring work, prolongs the application life of drilling rod simultaneously.The utility model can also effectively reduce airborne dust concentration; Improve the environment on coalface quality, improve workman's condition of work; The generation of prevention pneumoconiosis, and the working method of carrying out synchronously with dedusting of drilling also practiced thrift cost of production, improved operating efficiency greatly.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described further:
Fig. 1 is the syndeton sketch map of the utility model;
Fig. 2 is the structural representation of leading fountain head;
Fig. 3 is the sectional view of Fig. 2;
Fig. 4 is the structural representation of wet type drilling rod;
Fig. 5 is the sectional view of Fig. 4.
The specific embodiment
In conjunction with accompanying drawing, a kind of dust arrester of drilling comprises rig 1, and the water inlet of rig 1 is connected with high-pressure water 3 through aqueduct 2, and the delivery port of rig 1 connects the water guide duct 401 in the wet type drilling rod 4, the other end of wet type drilling rod 4 with lead fountain head 5 and be fixedly connected.In the set inside of leading fountain head 5 conflux groove 501 that is connected with water guide duct 401 and a plurality of tapping holes road 502 that is connected with conflux groove 501 are arranged; Tapping hole road 502 is parabola shaped; And axial symmetry distributes, and the delivery port 503 in tapping hole road 502 evenly distributes in the outer rim of leading fountain head cross section projection.The other end of leading fountain head 5 is fixedly connected with drill bit 6.
Like this when rig is worked; Plus high-pressure water source 3 and aqueduct 2, rig 1, wet type drilling rod 4, lead between the fountain head 5 and form water-flowing path; And when the water guide duct 401 of current through wet type drilling rod 4 flow to when leading fountain head 5, under the effect of conflux groove 501, current are keeping turning to tapping hole road 502 under the constant basically situation of original flow velocity; Be converted into the mud outflow at last through delivery port 503 edges and the opposite direction ejection of water guide duct 401 interior current, and with mix dust.
Further; Link at wet type drilling rod 4 is provided with lug boss 7, in the corresponding end of leading fountain head 5 connecting portion 8 is set, and on lug boss 7 and connecting portion 8, is provided with pin hole 9; During connection; Earlier lug boss 7 is inserted in the connecting portion 8, it is fastening in pin hole 9, to insert pin then, can realize wet type drilling rod 4 and lead being fixedly connected of fountain head 5.
Need to prove that under the instruction of this manual, any equivalents that those skilled in the art have done, or obvious variant all should be within the protection domains of the utility model.
Claims (2)
1. dust arrester of drilling; Comprise rig, wet type drilling rod and drill bit; It is characterized in that: between wet type drilling rod and drill bit, be provided with and make the fountain head of leading that current oppositely spray in the wet type drilling rod; The said set inside of leading fountain head have with the wet type drilling rod in the conflux groove that is connected of water guide duct and a plurality of tapping holes road that is connected with the conflux groove, the tapping hole road is parabola shaped, and the delivery port in tapping hole road evenly distributes at an end outer rim place that leads fountain head.
2. a kind of dust arrester of drilling according to claim 1 is characterized in that: also comprise high-pressure water, high-pressure water is connected with the water inlet of rig through aqueduct.
