Abstract
The invention discloses a rock-entering drill bit structure manufactured by utilizing the principle that a rock stratum is easy to break after being cut into single cylinders. The rock-entering drill bit structure is high in rock stratum layer drilling speed and high in efficiency and is used in cooperation with a pile machine impactor. The rock-entering drill bit structure comprises a rock-entering drill bit and an inner drill bit arranged in the rocking-entering drill bit. An air channel is formed in the middle of the inner drill bit. A plurality of blowing channel holes communicated with the lower end of the air channel are formed in the conical head of the lower end of the inner drill bit uniformly. The blowing channel holes are communicated with an internal cavity of the rock-entering drill bit. A plurality of inner drill bit alloy protecting teeth are arranged on the surface of the conical head of the lower end of the inner drill bit. A plurality of rock-entering drill bit alloy protecting teeth are arranged on the inner wall and the lower end head of the rock-entering drill bit. A plurality of reverse muck notches are formed in the lower end head of the rock-entering drill bit uniformly. A plurality of reverse muck air channels communicated with the reverse muck notches are formed in the rock-entering drill bit.
Description
Technical field
The present invention relates to a kind of stake mechanomotive force head, particularly relate to impactor on a kind of machine matching used enter rock drill bit structure.
Background technology
During pile foundation construction, need to use a machine, stake machine drives bit by power set, pile boring is carried out to ground, as run into the harder rock stratum of ground, the impactor on existing stake machine supporting enter rock drill bit structure rate of penetration slow, inefficiency.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of enter impactor on rock speed is fast, efficiency is high stake machine matching used enter rock drill bit structure.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: enter rock drill bit structure, comprise: enter rock drill bit and be arranged on the interior drill bit into rock drill bit internal, the middle part of described interior drill bit is provided with air flue, the insufflation channel hole that some and described air flue lower end is connected evenly is provided with in the conical nose of interior drill bit lower end, described insufflation channel hole is connected with the internal cavities entering rock drill bit, some interior drill bit alloy protective teeth are provided with on the surface at the conical nose of described interior drill bit lower end, described enter the inwall of rock drill bit and lower end head are all provided with some enter rock drill bit alloy protective tooth, described enter rock drill bit lower end head on be evenly provided with some anti-dregs breach, at the described anti-dregs air flue entering rock drill bit is provided with some and anti-dregs breach and be connected.
Advantage of the present invention is: above-mentioned enter rock drill bit structure, structure is simple, can hole to harder rock stratum, rock can be smashed rapidly, carg after smashing can be transferred out outlet easily, and enter rock stratum relatively easy, operating efficiency is high.

Detailed description of the invention
Particular content of the present invention is described in detail below in conjunction with the drawings and specific embodiments.
As Fig. 1, Fig. 2, shown in Fig. 3, enter rock drill bit structure, comprise: the interior drill bit 2 entering rock drill bit 1 and be arranged on into rock drill bit 1 inside, the middle part of described interior drill bit 2 is provided with air flue 3, the insufflation channel hole 5 that some and described air flue 3 lower end is connected evenly is provided with in the conical nose 4 of interior drill bit 2 lower end, described insufflation channel hole 5 is connected with the internal cavities 6 entering rock drill bit 1, some interior drill bit alloy protective teeth 7 are provided with on the surface at the conical nose 4 of described interior drill bit 2 lower end, described enter the inwall of rock drill bit 1 and lower end head are all provided with some enter rock drill bit alloy protective tooth 8, described enter rock drill bit 1 lower end head on be evenly provided with some anti-dregs breach 9, at the described anti-dregs air flue 10 entering rock drill bit 1 is provided with some and anti-dregs breach 9 and be connected.
As shown in Figure 3, above-mentioned enter rock drill bit structure install time, the upper end of interior drill bit 2 is connected with the lower end of impactor 13 with boring centring ring 12 by drive joint 11, oversheath 14 is arranged on the outside of impactor 13, oversheath 14 is evenly provided with spiral conveying blade 15, during use, enter rock drill bit 1 be subject to piston 16 in impactor 13 that its top compression air is power constantly bob impact.Be subject to drive joint 11 that unit head drives to rotate and carry out rock stratum and impact cutting simultaneously, cut into the fragmentation that cylindrical rock 18 is subject to the conical nose 4 of interior drill bit 2, become dregs soon, compressed air enters internal cavities 6 by air flue 3, insufflation channel hole 5 and jets to its inside dregs, dregs after pulverizing, by anti-dregs breach 9, anti-dregs air flue 10, is transferred out aperture under the effect of spiral conveying blade 15.
Above-mentioned enter rock drill bit structure, structure is simple, make use of rock stratum be cut into single cylinder after breakable principle carry out rock stratum and creep into, operating efficiency is high.
