Description
Technical field
Broken screw thread deslagging base plate efficient drilling drill bit device in the present invention relates to be 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 base plate non-support
Distension increasingly manifests.Strengthening the improvement of pucking must study its Mechanism of Deformation And Failure, and it is phase to develop roadway floor efficient drilling equipment
Close the basis of research.Different from top, side drilling, boring mud can realize simple deslagging by deadweight, and base plate drilling drilling cuttings discharge is difficult,
Particularly deep hole, superdeep holes creep into.
At present, roadway floor drilling drilling mode is mainly：Crept into using top board rig, by the side of the pneumatic aperture blowing of high pressure
Formula carries out deslagging；Drilled with its supporting twist drill rods using electric coal drill, arranged simply by the spiral of twist drill rods
Slag；Drilled by propulsive force high using all-hydraulic tunnel drilling rig.The shortcoming of first two mode is effectively to be arranged
Slag, causes rate of penetration slow and drills shallow；The equipment that the third method is used is heavy, operating difficulties, and speed is slow, efficiency
It is low.Nowadays during in the market majority base plate drilling drilling, the friction that traditional drilling tool is still relied upon between single drill bit and rock comes
Drilling is realized, so that drilling efficiency and depth are very limited, when rock is softer, easy collapse hole bit freezing, when running into higher-strength
During rock, the speed of drilling is low, therefore high in the urgent need to designing a kind of drilling efficiency, the big base plate efficient drilling dress of drilling depth
Put.
The content of the invention
For above-mentioned situation, to overcome the deficiencies in the prior art, the invention discloses broken screw thread deslagging bottom in being bored outside one kind
Plate efficient drilling drill bit device, many asking its purpose is to effectively solve coal mine underground space engineering base plate drilling drilling
Topic, smoothly realizes that base plate drilling high-efficiency creeps into.
To realize object above, the technical scheme that the present invention is solved is：One section of anterior connection of hollow cylindrical attachment means
Body is connected with coring bit afterbody connector, and attachment means inner ring is connected through a screw thread with drill bit afterbody is crushed, in attachment means
Between be provided with breach as slagging channel, crushing drill bit medium design has apopore, crushes drill bit afterbody connector anterior with drilling rod
Connector is connected, and drilling rod is auger stem, double ingenious combinations of drill bit, realizes broken in outer brill, and deslagging is carried out with reference to auger stem.
Double drill bits are cleverly combined the beneficial effects of the invention are as follows in roadway floor drilling drilling process, realizes that rig revolves
Enter rock break-off process China and foreign countries and bore interior broken integration, apparatus structure is simple, easy to operate, and reply deep well drilling effect is good, greatly improves
The drilling efficiency of base plate drilling, is the innovation on roadway floor efficient drilling device, with significant economic and social benefit.

Specific embodiment
To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, with reference in the embodiment of the present invention
Accompanying drawing, clear, complete description is carried out to the technical scheme in the embodiment of the present invention, it is clear that described embodiment is this
A kind of embodiment in invention, rather than whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art
The every other embodiment obtained on the premise of creative work is not made, belongs to the scope of protection of the invention.Need
It is noted that accompanying drawing using very simplify in the form of and use non-accurately ratio, only with facilitate clearly auxiliary say
The purpose of the bright embodiment of the present invention.
Specific embodiment of the invention is elaborated below in conjunction with accompanying drawing.
Broken screw thread deslagging base plate efficient drilling drill bit device in a kind of outer brill, it is characterised in that one section of hollow cylindrical connects
The anterior connector of connection device 2 is connected with the afterbody connector of coring bit 1, and attachment means inner ring 6 passes through spiral shell with the afterbody of drill bit 4 is crushed
Line 3 is connected, and breach 15 is provided with the middle of attachment means 2 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 the anterior connector of drilling rod 7, and drilling rod 7 is auger stem, and double ingenious combinations of drill bit realize 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 is threadedly connected with the afterbody of drill bit 4 is crushed, the jagged work of the medium design of attachment means 2
It is slagging channel 15, the described afterbody of crushing drill bit 4 is round table-like in convex, has 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 rotates the coupled drilling rod of threading by external screw thread 12
In 7, crushing has hole for water spraying 8 and buffer mouth 11 in the middle of drill bit 4, and the aperture that the indoor design of drilling rod 7 has water injection pipe 10, hole for water spraying 8 is omited
Less than the caliber of water injection pipe 10.
Service condition of the invention is, when drilling machine digs drilling, rig slewing equipment drives drilling rod and drill bit revolution, takes
The rotation propulsion broken rock coring of core drill bit 1, as drill bit 1 creeps into forward, ore is elapsed backward, and rearmounted crushing drill bit 4 touches ore deposit
Stone is simultaneously crushed, that is, realize broken in the outer brill of drilling drilling process.At the same time, water under high pressure is through water filling in auger stem 7
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 is by double brills
Slagging channel 15 is smoothly arranged to auger stem 7 in head attachment means, and deslagging is carried out with reference to auger stem, and device is reciprocal with this principle
Drilling deslagging.When drill bit destruction needs to change dismounting, the crushing afterbody of drill bit 4 and the anterior spiral shell of drilling rod 7 are turned on by special wrench set
Line coupling part, then turns on coring bit 1 and crushes the attachment means inner ring and the threaded joints for crushing drill bit 4 of drill bit 4
Point, 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
Change after finishing with this principle device for screwing up coupling part, just complete the dismounting and installation of the device.
