Technical field
It the utility model is related to broken screw thread deslagging bottom plate efficient drilling drill bit device in being bored outside one kind.
Background technology
With the increase of the mining depths such as colliery, metallic ore, the increase of drift section, the strong bottom caused by bottom plate non-support
Bottom distension increasingly shows.Its Mechanism of Deformation And Failure must be studied by strengthening the improvement of pucking, and developing roadway floor efficient drilling equipment is
The basis of correlative study.Drilled different from pushing up, helping, boring mud can realize simple deslagging by deadweight, and bottom plate drilling drilling cuttings discharge is stranded
Difficulty, particularly deep hole, superdeep holes drilling.
At present, roadway floor drilling drilling mode is mainly：Crept into using top plate rig, pass through the side of the pneumatic aperture blowing of high pressure
Formula carries out deslagging；Drilled using electric coal drill and its supporting twist drill rods, arranged simply by the spiral of twist drill rods
Slag；Drilled using all-hydraulic tunnel drilling rig by high propulsive force.The shortcomings that first two mode is effectively to be arranged
Slag, cause rate of penetration slow and drill shallow；The equipment that the third method uses is heavy, operating difficulties, and speed is slow, efficiency
It is low.Meanwhile when nowadays the drilling of in the market majority bottom plate is crept into, traditional drilling tool still relies upon rubbing between single drill bit and rock
Wipe to realize drilling, so that drilling efficiency and depth are very limited, when rock is softer, easy collapse hole bit freezing is higher when running into
During intensity rock, the speed of drilling is lower, therefore high there is an urgent need to design a kind of drilling efficiency, and the big bottom plate of drilling depth is efficient
Drilling equipment.
Utility model content
It is overcome the deficiencies in the prior art for the above situation, the utility model discloses broken screw thread row in being bored outside one kind
Slag bottom plate efficient drilling drill bit device, its purpose is to effectively solve many of coal mine underground space engineering bottom plate drilling drilling
Problem, smoothly realize that bottom plate drilling high-efficiency is crept into.
To realize object above, the technical scheme that the utility model solves is：One section of hollow cylindrical attachment means is anterior
Connector is connected with coring bit afterbody connector, and attachment means inner ring is connected through a screw thread with crushing drill bit afterbody, connection dress
Put centre and be provided with breach as slagging channel, crushing drill bit medium design has hole for water spraying, crushes drill bit afterbody connector and drilling rod
The connection of anterior connector, drilling rod is auger stem, double ingenious combinations of drill bit, realizes broken in outer brill, is carried out with reference to auger stem
Deslagging.
The beneficial effects of the utility model are cleverly to combine double drill bits in roadway floor drills drilling process, realize and bore
Broken integration in machine precession rock break-off process China and foreign countries brill, apparatus structure is simple, easy to operate, and reply deep well drilling effect is good, significantly
The drilling efficiency of bottom plate drilling is improved, is the innovation on roadway floor efficient drilling device, there is significant economic and society
Benefit.

Embodiment
To make the purpose, technical scheme and advantage of the utility model embodiment clearer, with reference to the utility model
Accompanying drawing in embodiment, clear, complete description is carried out to the technical scheme in the embodiment of the utility model, it is clear that described
Embodiment be a kind of embodiment in the utility model, rather than whole embodiment.Based on the implementation in the utility model
Example, the every other embodiment that those of ordinary skill in the art are obtained on the premise of creative work is not made, all belongs to
In the scope of the utility model protection.It should be noted that accompanying drawing using very simplified form and using it is non-accurately
Ratio, only with facilitate clearly aid in illustrating the utility model embodiment purpose.
Specific embodiment of the present utility model is elaborated below in conjunction with accompanying drawing.
Broken screw thread deslagging bottom plate efficient drilling drill bit device in a kind of outer brill, it is characterised in that one section of hollow cylindrical connects
2 anterior connector of connection device is connected with the afterbody connector of coring bit 1, and attachment means inner ring 6 passes through spiral shell with crushing the afterbody of drill bit 4
Line 3 is connected, and breach 15 is provided among attachment means 2 and is used as slagging channel, and crushing the medium design of drill bit 4 has hole for water spraying 8, crushes and bores
First 4 afterbody connector is connected with 7 anterior connector of drilling rod, and drilling rod 7 is auger stem, double ingenious combinations of drill bit, realizes outer brill
It is interior broken, carry out deslagging with reference to auger stem.
In order to ensure using effect, described hollow cylindrical attachment means 2 are anterior to pass through screw thread with the afterbody of coring bit 1
3 connections, attachment means inner ring 6 are threadedly connected with crushing the afterbody of drill bit 4, the jagged work of the medium design of attachment means 2
For slagging channel 15, the described afterbody of crushing drill bit 4 is round table-like in convex, there is external screw thread 12 thereon, before coupled drilling rod 7
Portion is concave round table-like, there is internal thread 14 thereon, crushes the afterbody of drill bit 4 and puts into coupled drilling rod by the rotation of external screw thread 12
In 7, crushing has hole for water spraying 8 and buffer mouth 11 among drill bit 4, and the indoor design of drilling rod 7 has water injection pipe 10, and the aperture of hole for water spraying 8 is omited
Less than the caliber of water injection pipe 10.
Service condition of the present utility model is, when drilling machine digs drilling, rig slewing equipment drives drilling rod and drill bit to return
Turn, the rotation of coring bit 1 promotes broken rock coring, and as drill bit 1 is crept into forward, ore elapses backward, and rearmounted crushing drill bit 4 contacts
To ore and crushed, that is, realized broken in the outer brill of drilling drilling process.At the same time, water under high pressure is through in auger stem 7
Water injection pipe is delivered to foot of hole, rinses double drill bits and drilling, prevents bit freezing, and plays cooling effect, and the boring mud of crushing passes through
Slag-drip opening 15 is smoothly arranged to auger stem 7 in double drill bit connecting devices, carries out deslagging with reference to auger stem, device is past with this principle
Deslagging is crept into again.When drill bit, which destroys, needs to change dismounting, turn on the crushing afterbody of drill bit 4 by special wrench set and drilling rod 7 is anterior
Part is threadedly coupled, coring bit 1 is then turned on and crushes threaded joints of the attachment means inner ring of drill bit 4 with crushing drill bit
Divide, finally turn on the threaded connection part of coring bit 1 and attachment means 2, it is possible to more bit change or device as requested, more
With this principle device for screwing up coupling part after changing, the disassembly and installation of the device is just completed.
