A kind of impingement jet bit
Technical field
The invention belongs to the technical equipment fields such as oil-gas drilling engineering, mining, geological drilling, construction work, construction of tunnel, shield structure and no-dig technique, be specifically related to a kind of Spiral digging machine impingement jet bit and fall.
Background technology
Existing Spiral digging machine is when rock drilling is constructed, drill bit pick alloy is when rock drilling, because high temperature can not fully cool, alloy is easy to wear or fracture in the event of high temperatures, time serious, drill bit can be out of shape, and steel part easily melts stuck in rock, and Rock penetrating difficulty is large, Spiral digging machine rate of penetration is slow, the problems such as fuel consumption is large.In order to fully be cooled when drill bit carries out brill rock, researcher is had to pass through to arrange water nozzle on drill bit, water nozzle can jet water course, boring the effect played cleaning, wash away and cool in the process of rock, but this kind of drill bit type of cooling in use, still there are some problems, as: when boring rock, solid granule easily enters in drill bit by water nozzle, causes water nozzle to block, cleaning cannot be played, the effect cooling and wash away; Drill bit output is comparatively large, is unfavorable for using water wisely; Chip not easily returns out.
Summary of the invention
For the above-mentioned technical problem that prior art exists, the invention provides a kind of impingement jet bit, by arranging air or water or mud compression bag at drill bit internal, ejected the jet-loop of certain pressure by compression bag, play the washing away of drill bit, to cool and chip returns out effect.
In order to solve the problems of the technologies described above, the technical scheme that the present invention takes, specific as follows:
A kind of impingement jet bit, it is characterized in that: comprise filtering slurry cover, link, mud compression bag, one way valve, vibrating disk, slide bar base and piston valve, wherein mud compression bag is set in link, filtering slurry cover is connected with the top board of mud compression bag, mud chamber is set in filtering slurry cover, mud chamber is connected with mud compression bag by one way valve, mud compression bag base plate is provided with into water mud mouth, described vibrating disk is provided with isocon, water inlet mud mouth connects the isocon of vibrating disk, isocon connects one end of piston valve, the other end of piston valve is fixed on slide bar base.
Described slide bar base arranges edge alloy and bottom alloy.
Described slide bar base is provided with jet buffer groove in piston valve exit.
Described piston valve quantity is more than 2.
The cross section of mud compression bag is the one in circle, ellipse, regular polygon.
The filler of mud compression bag is the mixture of one or more in water, air and mud.
Above-described drill bit circulating jet method, after mud is filtered by filtering slurry cover, enter mud chamber, mud chamber flows into mud compression bag by one way valve, air or water or mud are moved down by drilling rod and apply pressure to mud compression bag, and when after air or water or pressure slurry to preset value, piston valve holds up vibrating disk, air or water or mud discharge pressure release from cylinder body, and air or water or mud form high-pressure spray and sprays bottom drill bit.
Beneficial effect of the present invention
1, drill bit of the present invention applies pressure by drilling rod to compression bag, high-pressure slurry or air or water jet is ejected in the middle part of slide bar base, rock debris also returns out by auxiliary drill bit cutting rock, cool drill bit alloy simultaneously and extend drilling life of bit, improve the efficiency of boring and reduce the use cost of oil consumption and drill bit.
When 2, boring rock, water jet ejection high-pressure spray, solid granule not easily passs through water nozzle and enters in drill bit, and water nozzle not easily blocks, and drill bit is not easy to be subject to high temperature failure, bores rock efficiency and greatly improves.
3, the high-pressure spray that drill bit ejects can not only play cleaning, cools and washes away the effect of drill bit alloy, can also assist drill bit cutting rock.
4, drill bit spray mud or water reusable edible, save new water consumption.High-pressure spray also plays the effect that auxiliary drill rock chip returns out.

Detailed description of the invention
Impingement jet bit, comprise filtering slurry cover 1, link 2, mud compression bag 3, one way valve 4, vibrating disk 7, slide bar base 8 and piston valve 12, wherein in link 2, mud compression bag 3 is set, filtering slurry cover 1 is connected with the top board of mud compression bag 3, mud chamber 6 is set in filtering slurry cover 1, mud chamber is connected with mud compression bag 3 by one way valve 4, and mud compression bag 3 base plate is provided with mud inlet 5, and described vibrating disk 7 is provided with isocon 11; Cement paste import 5 connects the isocon 11 of vibrating disk 7, and isocon 11 connects one end of piston valve 12, and the other end of piston valve 12 is fixed on slide bar base 8.
Air or water or mud will be filled it up with in mud compression bag 3 before using, drill rod sleeve people drill bit is placed on the center that need hole and spuds in.While drilling rod rotates, pressurizeed by drilling rod in top, the large I of pressurization is determined according to the hardness of rock and soil layer, alloy on bur slide base 8 is while be under pressure the circumgyration incision soil body and rock mass down creep into, mud compression bag 3 is being subject to upper pressure, high-pressure slurry promotion piston valve 12 holds up vibrating disk 7 and moves up, when after pressure slurry to preset value, the vibrating disk 7 that piston valve 12 holds up, discharges through piston valve 12 cylinder body and ejects the auxiliary cutting of pressure-air or water or slurry jet.And vibrating disc 7 produces the effect that impact and fractured rock quickening rate of penetration are played in vibrations when rock drilling.Up need carry when mud compression bag 3 is compressed completely and sprayed mud after brill allows mud compression bag 3 be filled air or water or mud and down creeping into again, during use, repeat above action.The operating principle of mud compression bag 3; Air or water or mud are by filtering slurry cover 1 inspiration mud chamber 6, (be air or water or mud or only mud is by filtering slurry cover 1 inspiration mud chamber 6) enters mud compression bag 3 by one way valve 4, then ejects high-pressure slurry jet by upper pressure through isocon 11, piston valve 12.
Application Example
At the constructing tunnel in building site, Guangxi, the granite in tunnel is harder, with normal drill bit pick alloy when rock drilling, temperature reaches 300 DEG C, does not add water cooling, alloy works in the event of high temperatures and namely weares and teares or rupture for 3-4 days, rear use impingement jet bit of the present invention, owing to adding cold water cooling, the temperature of drill bit rock drilling only 150 DEG C, application life is 25 days, bores rock efficiency and greatly improves.
