Being integral type with drillstock, the installation so causing cutter head is cumbersome, or during cutter head erecting and welding, can affect drilling rod surface
Precision.
Utility model content
The technical problems to be solved in the utility model is, overcomes the defect of above prior art, it is provided that a kind of cutter head is easy for installation,
The drill bit of processing blind hole on rock that chip removal speed is fast and drilling efficiency is high.
Technical solution of the present utility model is to provide a kind of drill bit of processing blind hole on rock with following structure:
It includes that drillstock, drilling rod and cutter head, the lower surface of described drilling rod are provided with the circular indent of one and drilling rod coaxial line, described drilling rod
Lower section be provided with a tool tip, the top of described tool tip is provided with a cylindrical boss, and described cylindrical boss is fixedly connected on
In circular indent；The lower circumferential wall of described tool tip is provided with multiple cutter head groove, and described cutter head is fixedly connected in cutter head groove.
After using above structure, this utility model drill bit of processing blind hole on rock compared with prior art, has following excellent
Point: this is used on rock being provided with below the drilling rod of the drill bit of processing blind hole tool tip, and the top of tool tip is provided with cylindrical boss,
Described cylindrical boss is fixedly connected in the circular indent on drilling rod lower surface, so when cutter head is installed in processing, and only need to be
Carry out erecting and welding cutter head in tool tip, fix with drilling rod again after treating the cutter head welding of labyrinth and be connected, thus make cutter
The convenient welding of head, and during cutter head welded and installed, do not interfere with the surface accuracy of drilling rod.
As improvement, the circumferential wall of described drilling rod lower end is provided with multiple draw-in groove, and the bottom of draw-in groove is concordant with drilling rod lower surface；
The top of described tool tip is provided with multiple fixture block corresponding with draw-in groove position, drilling rod lower end, and described fixture block is all a tight fit in card
In groove.The fixture block at the top of tool tip is a tight fit in the draw-in groove of drilling rod lower end, and fixture block further limit with coordinating of draw-in groove
Circumferentially rotating of tool tip, so that the connection of tool tip is more firm.
As improvement, the lower surface of described tool tip is provided with multiple groove being distributed along its circumferencial direction, the company of fixing in each groove
Connect a lower cutter head.The setting of lower cutter head makes the drilling efficiency of this drill bit be greatly improved, and is suitable at highdensity concrete, rock
Hole on stone.
As preferably, the circumferential wall of described drilling rod is provided with a plurality of and drilling rod coaxial line chip area.
As improvement, on described drilling rod, the lower end of chip area is provided with a up big and down small taper seat.This taper seat also allows for boring
Time rock dust upwards discharge smoothly through chip area, packaging drill bit drilling efficiency.
