Description
Technical field
The present invention relates to roller cutter bit field, more particularly to a kind of rock drilling inserted tooth hob drill bit.
Background technology
Anti- well rig technological principle is by the motor belt motor hydrodynamic pressure motor of rig, fluid motor-driven tap, and profit
Drilling system is delivered torque to hydraulic power, drilling rod and bit, the hobboing cutter on guide hole drill bit or reaming bit is driven
In the presence of the pressure of the drill, pure rolling or micro sliding are done along bottom rock working face.The axial direction that main frame oil cylinder is produced simultaneously is drawn, pressure
Power, acts on guide hole drill bit or reaming bit also by unit head, drilling rod, the hobboing cutter of guide hole drill bit is rolled under the pressure of the drill effect
It is dynamic, impact load is produced, make hob teeth that impact, extruding and shear action, fractured rock are produced to rock.The cutter head of anti-well rig
It is fixed on drill main body by bearing.
Number of patent application discloses a kind of anti-well drill bit of drilling machine, including knife for the patent of invention of CN201520047492.X
Disk, drilling rod and be inlaid with the conical cutter head of steel alloy, the drilling rod vertical welding in the center of cutterhead, the conical cutter head
Be six, six big ends of conical cutter heads outwards, around the radial laying of drilling rod, and on the knife rest of cutterhead, in putting
Penetrate shape laying six conical cutter heads be followed successively by a cutter head, No. two cutter heads, No. three cutter heads, No. four cutter heads, No. five cutter heads and
No. six cutter heads, the minimum distance of the small end of a cutter head away from drilling rod is 60mm, a central axis for cutter head and cutterhead
Angle is 30 °；The minimum distance of No. three cutter heads and No. five small ends of cutter head away from drilling rod is 190mm, No. three cutter heads and No. five cutter heads
The angle of central axis and cutterhead be 20 °；The minimum distance of No. two cutter heads, No. four cutter heads and No. six small ends of cutter head away from drilling rod
It is 320mm, the central axis of No. two cutter heads, No. four cutter heads and No. six cutter heads and the angle of cutterhead are 10 °.The drill bit is by transformation
The discrepancy in elevation between cutterhead, cutter head and the angle between each cutter head and cutterhead, make working face of the drill bit on rock form one
Flared shape, so that the damage resistance power reduction of the rock that each cutter head is contacted, reduces cutter head unbalance stress
Phenomenon, the resistance of reduction cutter head rock suffered when working, and then reduce the moment of torsion of drilling rod and cutterhead, it is several that reduction drill bit is damaged
Rate, extends the service life of drill bit, improves operating efficiency.
But, the above-mentioned cutter head complex operation as the cutter head of conventional bit when mounted, because cutter head is more, it is necessary to even
More bolt is connect, service working time is more long, low production efficiency.When cutter head is dismantled, because cutter head is connected with drill main body
Place is covered by more landwaste, and dismounting is more difficult, and bolt may be stuck and cause cutter head to dismantle not get off.
The content of the invention
Instant invention overcomes the deficiencies in the prior art, there is provided a kind of easy disassembly rock drilling inserted tooth hob drill bit, solve existing
There is roller cutter bit to dismount complicated, service working time problem long.
