Description
Technical field
The present invention relates to the impactor on a kind of mechanomotive force head more particularly to a kind of machine it is matching used enter rock drill bit
Structure.
Background technology
During pile foundation construction, need to use stake machine, stake machine drives bit by power plant, ground is carried out into
Stake drilling, such as encounters the harder rock stratum of ground, and the impactor on existing stake machine is with being inserted in rock drill bit structure rate of penetration
Slowly, working efficiency is low.
Invention content
The technical problems to be solved by the invention are：There is provided it is a kind of enter fast, the efficient stake machine of rock speed on impactor
It is matching used enter rock drill bit structure.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：Enter rock drill bit structure, including：Enter rock brill
Head and be arranged on the interior drill bit into rock drill bit internal, be provided with air flue in the middle part of the interior drill bit, the cone in interior drill bit lower end
Several insufflation channel holes being connected with the air flue lower end are evenly arranged in forming head portion, the insufflation channel hole is with entering rock
The internal cavities of drill bit are connected, and several interior drill bit alloy protectives are provided on the conical nose surface of the interior drill bit lower end
Tooth, it is described enter the inner wall of rock drill bit and lower end head on be both provided with it is several enter rock drill bit alloy protective tooth, it is described enter rock bore
Be evenly arranged with several anti-dregs notches on the lower end head of head, it is described enter rock drill bit on be provided with it is several with anti-dregs notch
The anti-dregs air flue being connected.
It is an advantage of the invention that：It is above-mentioned enter rock drill bit structure, it is simple in structure, harder rock stratum can be bored
Hole can rapidly smash rock, and the carg after smashing can easily be conveyed out exporting, and hold into rock stratum is opposite
Easily, working efficiency is high.

Specific embodiment
The particular content of the present invention is described in detail in the following with reference to the drawings and specific embodiments.
As shown in Figure 1, Figure 2, Figure 3 shows, enter rock drill bit structure, including：Enter rock drill bit 1 and be arranged on into inside rock drill bit 1
Interior drill bit 2 is provided with air flue 3 at the middle part of the interior drill bit 2, if being evenly arranged in the conical nose 4 of interior 2 lower end of drill bit
The dry insufflation channel hole 5 being connected with 3 lower end of air flue, the insufflation channel hole 5 and the internal cavities 6 for entering rock drill bit 1
Be connected, several interior drill bit alloy protective teeth 7 be provided on 4 surface of conical nose of interior 2 lower end of drill bit, it is described enter rock
Be both provided on the inner wall of drill bit 1 and lower end head it is several enter rock drill bit alloy protective tooth 8, it is described enter rock drill bit 1 lower end
Several anti-dregs notches 9 are evenly arranged in portion, it is described enter rock drill bit 1 on be provided with and several be connected with anti-dregs notch 9
Anti- dregs air flue 10.
As shown in figure 3, it is above-mentioned enter the installation of rock drill bit structure when, the upper end of interior drill bit 2 is fixed by drive joint 11 and drilling
Position circle 12 is connected with the lower end of impactor 13, and oversheath 14 is arranged on the outside of impactor 13, is uniformly arranged on oversheath 14
There is spiral conveying blade 15, in use, it is the piston 16 in the impactor 13 of power to enter rock drill bit 1 by upper part compressed air
Constantly move up and down impact.The rotation of drive joint 11 driven simultaneously by power head carries out rock stratum impact cutting, cuts
The rock 18 of cylinder is cut by the broken of the conical nose 4 of interior drill bit 2, quickly becomes dregs, compressed air passes through gas
Road 3, insufflation channel hole 5 are blown its inside dregs into internal cavities 6, the dregs after crushing by anti-dregs notch 9,
Anti- dregs air flue 10, aperture is conveyed out under the action of spiral conveying blade 15.
It is above-mentioned enter rock drill bit structure, it is simple in structure, rock stratum is utilized and is cut into breakable principle after single cylinder
Rock stratum drilling is carried out, working efficiency is high.
