Description

One can open and close type diamond compact bit
Technical field
The utility model relates to for exploiting drill bit field, colliery, and being specially one can open and close type diamond compact bit.
Background technology
In process of coal mining, the gas in colliery is needed to extract out, for the sleeve pipe of guard aperture under generally in boring, the treating method of present stage is after first getting into certain position with drill bit, drill bit is taken out, and then setting of casing, but destroy the steadiness of rock stratum in the process due to drill bit probing, easily cause the blocking boring that comes off of rock stratum, can not to say under sleeve pipe on preposition, cause methane gas to be extracted out, and in current existing drill bit use procedure, the wearing and tearing of drill bit become a difficult problem in progress of coal mining, the sharp-pointed wearing and tearing easily causing drill bit of drill bit, increase and change number of times, the smooth of drill bit easily causes the stability of drilling drill bit in recovery process, drill bit cannot be got into fixing position, cause methane gas to extract to go wrong.
Utility model content
The technical problem that the utility model solves is to provide one can open and close type diamond compact bit, solves the problem proposed in above-mentioned background technology.
One can open and close type diamond compact bit, comprise: drill body, cutting edge, running drill core, draw-in groove, around hinged end, through hole, hollow drill body mouth, chip area, cutting alloy sword face, alloy blade, described drill body upper end arranges four cutting edges, cutting edge side is cutting alloy sword face, is provided with hollow drill body mouth in the middle of drill body.
Described drill body upper end is provided with the rotatable running drill core of horizontal in-line, running drill core one end is connected with around hinged end and is fixed on drill body, the other end is placed in draw-in groove, and running drill core is provided with four alloy blades, and wherein two alloy blades and two other alloy blade arrange in the other direction.
Chip area is formed between rotational trajectory between described four cutting edges.
Through hole is provided with between described four cutting edges.
Described cutting edge side is cutting alloy sword face.
Described cutting alloy sword face is provided with the alloy blade of step arrangement.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, can open and close type diamond compact bit, drill body is provided with running drill core can, after drill bit completes boring, can by the axially extending bore of sleeve pipe through drill main body, sleeve pipe can back down running drill core and pass drill bit, thus realize at drill bit internal setting of casing, can when not withdrawing from drill bit setting of casing, and then can ensure under sleeve pipe to precalculated position, running drill core is provided with alloy blade, cutting alloy blade face is provided with the alloy blade of step arrangement, increase acuteness and the stability of drill bit, alloy blade is diamond material, add the abrasion resistance of drill bit, according to improving application life, add stock-removing efficiency, be easy to universal use.
Accompanying drawing explanation
Fig. 1 is front view schematic diagram of the present utility model.
Fig. 2 is top view schematic diagram of the present utility model.
Detailed description of the invention
In order to make actualizing technology means of the present utility model, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, set forth the utility model further.
As shown in Fig. 1 ~ 2, one can open and close type diamond compact bit, comprise: drill body 1, cutting edge 2, running drill core 3, draw-in groove 4, around hinged end 5, through hole 6, hollow drill body mouth 7, chip area 8, cutting alloy sword face 9, alloy blade 10, drill body 1 upper end arranges four cutting edges 2, cutting edge 2 side is cutting alloy sword face 9, cutting alloy blade face 9 is provided with the alloy blade 10 of echelon formation, hollow drill body mouth 7 is provided with in the middle of drill body 1, drill body 1 upper end is provided with the rotatable running drill core 3 of horizontal in-line, running drill core 3 one end is connected with around hinged end 5 and is fixed on drill body 1, the other end is placed in draw-in groove 4, running drill core 3 is provided with four alloy blades 10, wherein two alloy blades 10 arrange in the other direction with two other alloy blade 10, chip area 8 is formed between rotational trajectory between four cutting edges 2, through hole 6 is provided with between four cutting edges 2.
The utility model structure is that hollow screw can open and close type diamond compact bit, drill bit need not be taken out in recovery process, also sleeve pipe can be carried out in the borehole, at preposition under guarantee sleeve pipe, alloy blade adds acuteness and the stability of drill bit, prevents drill bit from skidding in recovery process, improve stock-removing efficiency, drill bit is diamond material, adds the abrasion resistance of drill bit, improves application life.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and manual just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.Claimed scope of the present utility model is defined by appending claims and equivalent thereof.
