Description
Technical field
The present invention relates to a kind of Xiyanping injection equipment more particularly to a kind of more millings for the multiple-grooved cutting drilling rod that coal is boring
Knife process equipment.Belong to drilling equipment technical field.
Background technique
Mine gas improvement is the precondition of Safety of Coal Mine Production, and arrangement mash gas pumping drilling is mine gas prevention and control
Common measure.Currently, the domestic drilling rod generallyd use has following three kinds: one is the smooth surface drilling rod by wind-force or hydraulic slag discharging,
One is the auger stems for leaning on machine power deslagging, and one is by loose saturating and wind power slag-discharging the Three-edged drill stem of vortex.Above-mentioned three classes
Drilling rod has defect in weak seam drilling process: for smooth surface drilling rod in weak seam drilling process, deslagging ability is weak,
It is easy to happen drilling blocking；Auger stem is in weak seam drilling process, at the region that collapse hole or hole wall are obviously shunk, is easy
There is bit freezing, fall to bore phenomenon；Although Three-edged drill stem causes vortex flow under high-speed rotation, slagging channel is formed, due to this
Drilling rod is vortexed that the slagging channel to be formed is small, and deslagging ability is weak, when the collapse hole that drills, is easy to appear bit freezing phenomenon.
The cutting that a kind of deslagging ability is strong, pore-forming effect is good, drilling efficiency is high, drilling depth is deep has been researched and developed thus to bore
Bar.Cutting drilling rod when rotation, will form slagging channel (vortex in coal body drills in the vortex groove on the external cylindrical surface of drilling rod
Area), be conducive to hole drilling deslagging.Meanwhile the thread groove of drilling rod body surface layout has the effect of disintegrating slag and auxiliary deslagging cooling.
Air-flow or water flow enter from the intracorporal beam channel of drilling rod, carry slagging channel row of the cinder between drilling rod body and coal wall wall
Out, when collapse hole occurs in drilling, on the one hand the vortex groove of the external side of drilling rod has the function of loose cinder thoroughly, on the other hand forms vortex
Slagging channel, the active force between drilling rod and cinder are released, in conjunction with the disintegrating slag and auxiliary of the external side spiral groove of drilling rod
The deslagging ability of the effect of deslagging, drilling rod improves, and is less prone to bit freezing phenomenon, is conducive to improve drilling efficiency and drilling depth.
Cutting drilling rod traditional diamond-making technique is with lathe turning processing or one milling tool to be processed, in processing double flute or
Just need to repeat to process two when three traverse drill bars to three times, and one when milling cutter is processed since milling cutter tends on one side, to entire bar
Body has lateral force, causes milling depth when long range milling that can change, thus leverages the production efficiency of drilling rod
And quality.
