Described face surface is located at the upper surface on position surface;Described inclined plane is located at the external margin on face surface;Described Drill bit be arranged in inclined plane;Described protection ball and aperture blowing are arranged on the surface of face;Described big landwaste groove and little landwaste Groove insertion position surface connects with bit body and with aperture blowing;Described protection ball include first raised and second raised, described the The one raised bottom being located at the second projection.
It is raised that the radius of curvature of the second described projection is more than first(81)Radius of curvature, enter on the surface of the first projection One step forms a relatively more sharp arcwall face, is conducive to building two-layer cambered surface protective layer, travels across in described bit body Cheng Zhong, the pressure of borings and frictional force are spread to surrounding, eventually pass through big landwaste groove and little landwaste groove is discharged.
Described big landwaste groove and little landwaste groove interval setting;Described big landwaste groove and little landwaste groove are all using 4 simultaneously 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.

Specific embodiment
With accompanying drawing, the present invention is described further with reference to embodiments:
Embodiment:
As shown in Figures 1 and 2
The present invention provides a kind of excavating bur scientific and reasonable for structure, including connecting shaft 1, bit body 2, and position surface 3, face surface 4, Inclined plane 5, big landwaste groove 6, little landwaste groove 7, protect ball 8, drill bit 9 and aperture blowing 10, described bit body 2 is arranged on connecting shaft 1 One end and on surface installation position surface 3;Described face surface 4 is located at the upper surface on position surface 3;Described inclined plane 5 is located at The external margin on face surface 4;Described drill bit 9 is arranged in inclined plane 5;Described protection ball 8 and aperture blowing 10 are arranged on face table On face 4;Described big landwaste groove 6 connects with bit body 2 and with aperture blowing 10 with little landwaste groove 7 insertion position surface 3;Described protection Ball 8 includes the first raised 81 and second projection 82, and the first described projection 81 is located at the bottom of the second projection 82.
