Abstract
The invention relates to the field of engineering machinery, in particular to a flushing drill bit. The flushing drill bit comprises a drill rod, one end of the drill rod is a drill rod drilling end, and the other end of the drill rod is a drill rod connecting end. Rigid protruding blocks are evenly arranged on the end face of the drill rod drilling end, spiral blades are fixed to the side face of the drill rod, a center water guide chute is formed in the axis of the drill rod connecting end, a water outlet channel is formed in the drill rod, and the water outlet channel is communicated with the center water guide chute and the outside of the drill rod. The flushing drill bit has the advantages that in the drilling process of the drill bit, soil and rock which are being drilled can be flushed with water through the center water guide chute and the water outlet channel, and therefore the humidity of the soil and rock which are being drilled can be improved, and the hardness of the soil and rock which are being drilled can be reduced; moreover, the drill bit can be cooled with water, damage to the drill bit caused by high temperature is reduced, the damage rate of the drill bit is reduced, and drilling efficiency is improved.
Description
Technical field
The present invention relates to engineering machinery field, relate in particular to a kind of flushing drill bit.
Background technology
Bored pile is the pile foundation type more widely of application at present, when single pile bearing requirement is larger, much all requires pile foundation to enter the hard rocks such as middle weathering or gentle breeze.At present, the normal rotary drilling rig hole forming method using is in being used the process of drill bit, due to soil or rock too dry, the soil or the formation hardness that are are too high, drill bit in the process of using with the fierceness friction of soil or rock, temperature of diamond bit raises, the long-term at high temperature boring of drill bit there will be serious damage, affects the application life of drill bit, can affect the progress of engineering in engineering due to the damage of drill bit, the efficiency that has reduced boring, even can produce security incident.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of flushing drill bit, can improve the efficiency of boring, reduces the infringement of drill bit, improves the application life of drill bit.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of flushing drill bit, comprise drilling rod, one end of described drilling rod is drilling rod drill end, the other end is drilling rod link, on the end face of described drilling rod drill end, be evenly provided with rigidity projection, on the side of described drilling rod, be fixed with flight, the axle center of described drilling rod link is provided with central guiding tank, in described drilling rod, be provided with exhalant canal, described exhalant canal is communicated with central guiding tank and drilling rod is outside.
On the basis of technique scheme, the present invention can also do following improvement.
Further, described flight is welded on described drilling rod.
Further, the exit of described central guiding tank on drilling rod link is provided with the mouth that is threaded.
Further, the mouth that is threaded described in locates to be provided with sealing mat.
Further, the side of described screw rod link is provided with screw thread.
The invention has the beneficial effects as follows: in the process of bit bore, can to the Soil and Rock of holing, carry out water flushing by central guiding tank and exhalant canal, improve the humidity of the Soil and Rock of holing, thereby reduce the hardness of the Soil and Rock of holing, and drill bit is carried out to water for cooling, reduce the infringement of high temperature to drill bit, reduced the damage probability of drill bit, improved the efficiency of boring.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is external structure of the present invention.
In accompanying drawing, the list of parts of each label representative is as follows:
1, drilling rod, 2, rigidity projection, 3, flight, 4, central guiding tank, 5, exhalant canal, 6, the mouth that is threaded, 7, sealing mat, 8, screw thread, 9, drilling rod drill end, 10, drilling rod link.
The specific embodiment
Below in conjunction with accompanying drawing, principle of the present invention and feature are described, example, only for explaining the present invention, is not intended to limit scope of the present invention.
As shown in Figure 1 and Figure 2, the present invention includes drilling rod 1, one end of described drilling rod 1 is drilling rod drill end 9, the other end is drilling rod link 10, on the end face of described drilling rod drill end 9, be evenly provided with rigidity projection 2, be fixed with flight 3 on the side of described drilling rod 1, the axle center of described drilling rod link 10 is provided with central guiding tank 4, in described drilling rod 1, be provided with exhalant canal 5, described exhalant canal 5 is communicated with the outside of central guiding tank 4 and drilling rod 1.Described flight 3 is welded on described drilling rod 1, and the exit of described central guiding tank 4 on drilling rod link 10 is provided with and is threaded mouthfuls 6, described in mouthful 6 places that are threaded be provided with sealing mat 7, the side of described screw rod link 10 is provided with screw thread 8.
Operating principle: drilling rod 1 is fixed on auger by the screw thread 8 on drilling rod link 10, the mouth 6 that is threaded is threaded connection water pipe, water pipe connects water pump, open auger, thereby auger drives drill bit to rotate and holes on soil or rock, open water pump, hydraulic pressure is entered to central guiding tank 4, from exhalant canal 5, flowing out and entering in the hole of boring, moistening hole soil or rock around, thereby reduce the hardness of soil or rock, improve the efficiency of boring, and reduce the temperature of drill bit, avoid temperature of diamond bit too high and rub by force and cause damaging, improve the application life of drill bit.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
