Abstract
Anchor rig target drill of a kind of end, comprise the cylindrical drill bit body that top is in-line major cutting edge, symmetrically on inclined-plane, in-line major cutting edge both sides have clear water spray orifice and end is the chip area of auxiliary-blade, the sewage routeway communicated with chip area is had in the middle part of bit body, the periphery of sewage routeway has the water-dilution channel communicated with clear water spray orifice, the bottom inner hole wall of bit body is offered the screwed hole that end anchor rig matches.The present invention not only can carry out the boring of friendship effect to mine floor, can also realize creeping into, clear up, blowdown carries out simultaneously, solve traditional bore mode easily causes plug-hole problem at construction of bottom plates, save and move back the very loaded down with trivial details working programme such as brill, clear hole in drilling process, its structure is simple, strong adaptability, easily operates, and blocking-proof result is good.
Description
Technical field
The present invention relates to a kind of drill bit, particularly a kind of end anchor rig target drill being applicable to the anti-blocking rapid cleaning construction of coal mine down-hole drilling.
Background technology
Along with the fast development of China's economic construction, energy demand is very big, and coal resources are difficult to change as the main source of China's energy supply in the future for a long period of time, causes coal industry constantly towards mechanization, automation direction development.The most colliery of China is due to reasons such as coal petrography character, buried depth, geostatic stress, and Floor Heave in Roadway destroys serious, have impact on tunnel use safety, constrains the safety in production of mine, and therefore jacking of floor management task is arduous.
Present stage, China is bolt support for the main means of mine floor Reinforcement.At present, the domestic anchoring device development specially for baseboard of coal mine roadway is little.And the wet method bore mode that typical anchoring device uses now is the hollow drill pipe water under high pressure having fixing water source to provide directly being injected rotation, the mud mixture formed is squeezed out by the gap of drilling rod and coal (rock) layer.There are some technical problems when mine floor carries out operation in this kind of wet method bore mode: first, the mud mixture squeezed out can not be collected with drilling rod splashes, have impact on normal transport and workman's walking in tunnel, floor rocks inundated intenerating exacerbates pucking problem simultaneously; Secondly, traditional bore mode easily causes plug-hole at construction of bottom plates, moves back brill, the work of clear hole is very loaded down with trivial details, had a strong impact on the efficiency of construction of base plate anchoring in drilling process; 3rd, in boring, coal (rock) powder enters tunnel, exacerbates the difficulty of tunnel treating flour dust, and harm workman is healthy.Therefore, develop a kind of realize safe and simple install, rapid cleaning construction base plate boring target drill for present stage coal production, there is important use value.
Summary of the invention
The object of the invention is for problems of the prior art, provide that a kind of structure is simple, small investment, integrate the mine floor anchoring target drill of boring, clearly hole, dirt eliminating function.
The end of the present invention anchor rig target drill, comprise cylindrical drill bit body, bit body comprises clear water spray orifice and chip area, the bottom inner hole wall of bit body is offered the screwed hole matched with end anchor drilling rod, sewage routeway is had in the middle part of bit body, the periphery of sewage routeway has the water-dilution channel communicated with clear water spray orifice, and sewage routeway communicates with chip area; Described bit body comprises the major cutting edge that top is in-line, and described chip area is opened in along columnar shaft to symmetry on the cylinder of in-line major cutting edge both sides, and chip area end is auxiliary-blade, and described clear water spray orifice symmetry is opened on inclined-plane, in-line major cutting edge both sides.
The clear water spray orifice that described symmetry is offered is 2-8; The cross section of described chip area is arc or right angle type.
Beneficial effect: the present invention not only can carry out efficient drilling to mine floor, can also realize creeping into, clear up, blowdown carries out simultaneously.Cleaning is washed away by the coal/rock dust of pressurization clear water to boring tip position, and by intermediate waste passage, termination sewage is extracted out, arc line shaped auxiliary-blade energy scraped finish borehole wall, ensure that boring is better shaped, effectively ensure that the blocking-proof result that mine floor anchoring is holed, solve traditional bore mode easily causes plug-hole problem at construction of bottom plates, save and move back the very loaded down with trivial details working programme such as brill, clear hole in drilling process, greatly improve the efficiency of construction of base plate anchoring.Its structure is simple, and strong adaptability, easily operates, and has practicality widely.

Detailed description of the invention
Below in conjunction with accompanying drawing, one embodiment of the present of invention are further described:
The end of the present invention anchor rig target drill, comprise cylindrical drill bit body, bit body comprises clear water spray orifice 2 and chip area 3, the bottom inner hole wall of bit body is offered the screwed hole 7 matched with end anchor drilling rod, sewage routeway 5 is had in the middle part of bit body, the periphery of sewage routeway 5 has the water-dilution channel 6 communicated with clear water spray orifice 2, and sewage routeway 5 communicates with chip area 3; Described bit body comprises the major cutting edge 1 that top is in-line, described chip area 3 is opened on the cylinder of in-line major cutting edge 1 both sides along columnar shaft to symmetry, chip area 3 end is auxiliary-blade 4, and described clear water spray orifice 2 symmetry is opened on inclined-plane, in-line major cutting edge 1 both sides.
The course of work: after drill bit is connected by drill bit bottom interior wall screwed hole 7 with supporting drilling rod, rig drives drill bit rotational by drilling rod, carries out boring work.Clear water is by water-dilution channel 6, spray from clear water spray orifice 2, do not stop cleaning drill bit major cutting edge 1, reduce temperature of diamond bit, the rock dust got out and aqueous mixtures enter sewage routeway 5 from chip area 3, and sewage is extracted out by the soil pipe of supporting drilling rod, while major cutting edge 1 holes cutting, auxiliary-blade 4 scraped finish hole wall, thus ensure that boring is better shaped.Efficiently solve the problem easily causing plug-hole in conventional borehole mode at construction of bottom plates, save and move back the very loaded down with trivial details working programme such as brill, clear hole in drilling process, achieve and creep into, clear up, carry out while blowdown operation.
