Description

A kind ofly to cut a hole into anti-blocking drill bit fast, simple to operate
Technical field
The utility model belongs to drilling tool field, specifically refers to a kind of cutter into anti-blocking drill bit fast, simple to operate.
Background technology
Bit of air drill is also known as bore bit, and its kind has yi word pattern, post flute profile, cross, horseshoe type.Bit of air drill is mainly applicable to mining engineering, excavation work and broken rock engineering, and in being applicable to, hard and solid rock carries out dry type and wet drilling.Existing Bit of air drill operationally, discharge mainly through the mud hole on Bit of air drill surface by the gravel particle of generation and mud, usually can blockage phenomenon, and normally carrying out into work is cut a hole in impact.
In addition, existing Bit of air drill is generally smooth plane foremost, very unfavorable for the lifting of cutting a hole into speed.
Utility model content
The purpose of this utility model is: overcome the above-mentioned defect of prior art, provides a kind of and cuts a hole into anti-blocking drill bit fast, simple to operate, and to reduce the generation of clogging, the cutter improving drill bit enters speed, and then promotes the operating efficiency of drill bit.
The utility model is achieved through the following technical solutions:
Cut a hole into an anti-blocking drill bit fast, simple to operate, comprise joint and bit body, the end of described bit body is connected with joint; The front end of described bit body is made up of three bit face, three bit face totally one ellipsoid, and three bit face form three fusiform structures; Be provided with deslagging inclined-plane between described bit face, described deslagging inclined-plane is provided with deslagging helicla flute, and described deslagging spiral fluted end is provided with mud hole.
Due to three bit face totally one ellipsoid, therefore during bit operation, chisel edge will form ellipsoid due to High Rotation Speed, compared with being smooth plane foremost with existing drill bit, the cutter that this kind of structure can promote drill bit enters speed, increases work efficiency, and simple to operate.
In addition, deslagging inclined-plane is provided with between bit face, deslagging inclined-plane is provided with deslagging helicla flute, the gravel particle that drill bit produces in the course of the work and mud are by the effect of deslagging spiral fluted, larger kinetic energy will be had, when mud hole is about to blocking occurs, gravel particle and mud will impact mud hole, avoid the generation blocked.
As the preferred mode of one, described bit body and joint one-body molded.Arranged by this kind, the stability that bit body is connected with joint can be strengthened, and be convenient to casting.
As the preferred mode of one, described bit face is provided with wear-resistant alloy layer, and described wear-resistant alloy layer is higher than the height of bit face.Arranged by this kind, effectively can promote the anti-wear performance of drill bit, extend the application life of drill bit.
As the preferred mode of one, described wear-resistant alloy layer is mottled.Arranged by this kind, the use of wear resistant alloy material can be reduced, reduce costs.
As the preferred mode of one, described wear-resistant alloy layer distributes symmetrically in three bit face.Arranged by this kind, can ensure that each position anti-wear performance of bit face is homogeneous, avoid subregion excessive wear to affect the follow-up work of drill bit.
The utility model compared with prior art, has the following advantages and beneficial effect:
(1) cutter that the utility model can promote drill bit enters speed, increases work efficiency, and simple to operate, effectively can reduce the generation of mud hole clogging;
(2) the utility model is provided with mottled wear-resistant alloy layer by bit face, effectively can not only promote the anti-wear performance of drill bit, extends the application life of drill bit, can also reduce the use of wear resistant alloy material, reduce costs;
(3) the utility model is distributed in three bit face symmetrically by wear-resistant alloy layer, can ensure that each position anti-wear performance of bit face is homogeneous, avoid subregion excessive wear to affect the follow-up work of drill bit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1-bit face, 2-bit body, 3-joint, 4-wear-resistant alloy layer, 5-deslagging inclined-plane, 6-deslagging helicla flute, 7-mud hole.
Detailed description of the invention
Below in conjunction with embodiment, the utility model is described in further detail, but embodiment of the present utility model is not limited thereto.
Embodiment 1:
See Fig. 1, a kind ofly to cut a hole into anti-blocking drill bit fast, simple to operate, comprise joint 3 and bit body 2, the end of described bit body 2 is connected with joint 3; The front end of described bit body 2 is made up of three bit face 1, three bit face 1 totally one ellipsoid, and three bit face 1 form three fusiform structures; Be provided with deslagging inclined-plane 5 between described bit face 1, described deslagging inclined-plane 5 is provided with deslagging helicla flute 6, and the end of described deslagging helicla flute 6 is provided with mud hole 7.
Due to three bit face 1 totally one ellipsoid, therefore during bit operation, chisel edge will form ellipsoid due to High Rotation Speed, compared with being smooth plane foremost with existing drill bit, the cutter that this kind of structure can promote drill bit enters speed, increases work efficiency, and simple to operate.
In addition, deslagging inclined-plane 5 is provided with between bit face 1, deslagging inclined-plane 5 is provided with deslagging helicla flute 6, the gravel particle that drill bit produces in the course of the work and mud are by the effect of deslagging helicla flute 6, larger kinetic energy will be had, when mud hole 7 is about to blocking occurs, gravel particle and mud will impact mud hole 7, avoid the generation blocked.
As the preferred mode of one, described bit body 2 is one-body molded with joint 3.Arranged by this kind, the stability that bit body 2 is connected with joint 3 can be strengthened, and be convenient to casting.
