Description
Technical field
This utility model relates to a kind of building pile foundation hole-forming device parts, particularly to a kind of long-spiral drilling machine
Hard rock drill bit.
Background technology
Long-spiral drilling machine pore-forming, building pile foundation construction technology are more ripe, and this technique suitability the most more comes
The strongest；But, the suitability to geology of the long-spiral drilling machine construction method, affected relatively big by geology soft or hard degree,
To harder rock stratum, long-spiral drilling machine is many not to be adapted to, and reason is that the cutting ability of drill bit is not enough；Cause
This, it is necessary to a kind of long-spiral drilling machine hard rock drill bit, it has stronger cutting ability, is applicable to harder
Rock stratum.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of long-spiral drilling machine hard rock drill bit, and it has
Stronger cutting ability, is applicable to relatively hard formation.
Long-spiral drilling machine hard rock drill bit of the present utility model, including drill body, described drill body connects
There is the topping machanism for cutting rock stratum；Described topping machanism includes cutting roller and for driving cutting roller
Driving motor.
Further, axial one end of described drill body is provided with the drilling rod connecting portion for being connected, axle with drilling rod
It is provided with the roller connecting portion for installing cutting roller to the other end.
Further, described drill body includes center-pole and is fixed on the helical-blade of described center-pole external cylindrical surface
Sheet, described roller connecting portion is located on helical blade.
Further, described center-pole is at least uniformly provided with three helical blades, the end of each helical blade
It is connected with at least two cutting roller.
Further, described driving motor by connect cable be connected with power supply, be provided with in described center-pole for
Lay the wire casing connecting cable.
Further, rotating shaft being radially arranged along center-pole of described cutting roller.
Further, the outer edge of described cutting roller is provided with alloy and bores tooth.
Further, described drilling rod connecting portion is for coordinating fixing jack structure with latch.
The beneficial effects of the utility model: long-spiral drilling machine hard rock drill bit of the present utility model has stronger cutting
Cut performance, simple in construction, easy to use, when long screw auger machine operation, can be replaced by as required in good time
This drill bit, during cutting hard rock, first starts cutting roller, and rear rotary drill rod rotates, down-cutting rock stratum, bores
When entering, cutting roller cutting rock stratum, drilling rod rotates to be taken out of boring mud in boring；This utility model is used to expand
The adaptability of big long-spiral drilling machine matter over the ground, makes long-spiral drilling machine both adapt to soft stratum, is also applicable to
Hard rock stratum.
Accompanying drawing explanation
With embodiment, this utility model is further described below in conjunction with the accompanying drawings:
Fig. 1 is the structural representation of the axial one end of drill body of the present utility model；
Fig. 2 is the structural representation of the axial other end of drill body of the present utility model.
Detailed description of the invention
As depicted in figs. 1 and 2: the long-spiral drilling machine hard rock drill bit of the present embodiment, including drill body, institute
State to connect on drill body and have the topping machanism for cutting rock stratum；Described topping machanism include cutting roller and
For driving the driving motor (not shown) of cutting roller 1；Cutting roller 1 and drive motor accordingly
Structure same as the prior art, do not repeat them here；Cutting roller 1 can design with driving motor integral,
Thus form electrodynamic type cutting roller；Cutting roller 1 has preferably cutting effect to hard rock, is integrated in brill
Its cutting ability can be effectively improved on head body；This drill bit has a stronger cutting ability, simple in construction,
Easy to use, when long screw auger machine operation, this drill bit can be replaced by as required in good time, during cutting hard rock,
First starting cutting roller 1, rear rotary drill rod rotates, and down-cutting rock stratum, when creeping into, cutting roller 1 cuts
Rock stratum, drilling rod rotates to be taken out of boring mud in boring；Use this utility model can expand long-spiral drilling machine to geology
Adaptability, make long-spiral drilling machine both adapt to soft stratum, also be applicable to hard rock stratum.
In the present embodiment, axial one end of described drill body is provided with the drilling rod connecting portion for being connected with drilling rod
4, the axial other end is provided with the roller connecting portion (not shown) for installing cutting roller 1；Roller is even
As long as the effect of fixing cutting roller 1 can play in the portion of connecing, such as, can be that seat design is installed；Described
Drill body includes center-pole 2 and is fixed on the helical blade 3 of described center-pole 2 external cylindrical surface, described roller
Connecting portion is located on helical blade 3, is i.e. located at the front end of helical blade 3；Cutting roller 1 is arranged on drill bit
Axial one end of body, and the rotating shaft of described cutting roller 1 being radially arranged along center-pole 2, it is possible to becoming
The effect first cut is played, to disintegrate hard rock during hole；And be at least uniformly provided with on described center-pole 2
Three helical blades 3, the end of each helical blade 3 is connected with at least two cutting roller 1, in order to brill
Basal bed, hole is cut comprehensively；The outer edge of described cutting roller 1 can be set up alloy and bore tooth 5, improves further
Its cutting ability；Described driving motor is connected with power supply by connecting cable, is provided with use in described center-pole 2
In laying the wire casing connecting cable, to realize power supply；Additionally, described drilling rod connecting portion 4 be preferably used for
Latch coordinates fixing jack structure, and during assembling, drilling rod is axially stretched into center-pole 2 and is fixed by latch
, it is simple to assembling.
Finally illustrate, above example only in order to the technical solution of the utility model to be described and unrestricted,
Although being described in detail this utility model with reference to preferred embodiment, those of ordinary skill in the art should
