Description
Technical field
The utility model is related to field of drill, more particularly to a kind of convenient disassembly inserted tooth hob drill bit.
Background technology
Lifting rig technological principle is the motor belt motor hydrodynamic pressure motor by rig, fluid motor-driven tap, and profit
Drilling system is delivered torque to hydraulic power, the hobboing cutter on drilling rod and bit, 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, is acted 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, hob teeth is produced impact, extruding and shear action, fractured rock to rock.Lift the cutter head of rig
It is fixed on by bearing on drill main body.
Number of patent application discloses a kind of anti-well drill bit of drilling machine, including knife for CN201520047492.X patent of invention
Disk, drilling rod and the conical cutter head for being inlaid with steel alloy, the drilling rod vertical welding is in the center of cutterhead, the conical cutter head
For six, the big ends of six conical cutter heads outwards, around drilling rod is radial is laid, 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, minimum distance of the small end away from drilling rod of a cutter head is 60mm, the central axis of cutter head and cutterhead
Angle is 30 °；Minimum distance of the small end away from drilling rod of No. three cutter heads and No. five cutter heads is 190mm, No. three cutter heads and No. five cutter heads
Central axis and the angle of cutterhead be 20 °；Minimum distance of the small end away from drilling rod of No. two cutter heads, No. four cutter heads and No. six cutter heads
For 320mm, the angle of No. two cutter heads, the central axis of No. four cutter heads and No. six cutter heads and cutterhead is 10 °.The drill bit passes through transformation
The angle between the discrepancy in elevation and each cutter head and cutterhead between cutterhead, cutter head, makes working face formation one of the drill bit on rock
Flared shape, so that the damage resistance power for the rock that each cutter head is contacted reduces, reduces cutter head unbalance stress
Phenomenon, the resistance of suffered rock during reduction cutter head work, 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, above-mentioned cutter head is when mounted as the cutter head of conventional bit
Complex operation, because cutter head is more, it is necessary to connect more bolt, service working time is longer, low production efficiency.In dismounting knife
During head, because cutter head is covered with drill main body junction by more landwaste, dismounting is more difficult, and bolt may be stuck and cause
Cutter head dismounting is not got off.
But, above-mentioned drill bit is extremely difficult when mounted.It is threadedly coupled between normal drill bit and drilling rod, if rotary drill bit
When drill bit is connected into drilling rod, drill bit is heavier, operating difficulties, also, the screw thread of drilling rod or drill bit is easily ground away, the pressure screwed
Power is not easily controlled.If connecting drill bit by way of rotating drilling rod, because drilling rod is longer whard to control.
