Lead to outside the junction of bit body and connecting shaft, be conducive to multi-angle, many chip discharged in time, it is to avoid chip amasss
It is pressed in face surface, it is worn and torn.
Described aperture blowing is arranged on face surface top and is connected with big landwaste groove and little landwaste groove;Described aperture blowing is in face table
Face is evenly arranged, and is conducive to, during bit body advances, assisting the discharge of landwaste using pneumatics pressure, making chip removal effect more
Good.
The gradient of described inclined plane is between 30 ° to 45 °;Described drill bit is vertically mounted in inclined plane, favorably
In providing more preferably bore angle, improve drilling rate.
The diameter with diameter greater than connecting shaft of described bit body, is conducive to that bit body is remaining in mining process to be gone out to supply landwaste
The space discharged.
Described drill bit outer surface is covered with one layer of these diamond layers having diamond sintering, is conducive to protecting drill bit, extends
Service life.
The present invention has the advantages that:Excavating bur a kind of scientific and reasonable for structure due to the present invention is extensively applied
In drilling equipment technical field.Meanwhile, beneficial effects of the present invention specifically can be described as:
1. the present invention first is raised and being equipped with of the second projection, and is conducive to the chip producing boring, internal pressure to carry out
Arc buffering simultaneously guides to big landwaste groove and little landwaste groove, drains into outside, reduces internal pressure and reduces friction, beneficial to carrying
The service life of high bit body.
2. the setting of aperture blowing of the present invention, is conducive to helping the discharge of landwaste using air pressure inside.
3. the setting of inclined plane of the present invention, is conducive to mitigating drill pressure, improves drilling life of bit.
