Abstract
The utility model discloses roof-bolter drilling tail baffle device for water, it includes cylindric sheath, outer diameter of the internal diameter and drilling tail of sheath one end close to drilling rod one end matches, and is bolted with ring baffle in the inside of the sheath other end, the axis of ring baffle and the axis of sheath are on same straight line.The utility model has the advantage of：After the utility model is installed in drilling tail end, so that the water leaked out, which is dissipated to splash from four, to be become spraying from the centre bore of ring baffle, the clothes for spattering staff with water is avoided, work comfort is improved；Tubaeform deflector is equipped with inside sheath, leak can be moved along deflector to be sprayed from the centre bore of ring baffle, and avoiding directly impact ring baffle causes ring baffle to be worn；It is movably equipped with resistance to mill tube in sheath, prevents jacket inner wall from being worn for a long time by leak splash, extends the service life of sheath, resistance to mill tube is replaceable, easy to use.
Description
Technical field：
The utility model relates to jumbolters, and in particular to a kind of roof-bolter drilling tail baffle device for water.
Background technique：
Roof-bolter is connect by drilling tail with drilling rod, in boring procedure, needs to supply water into drilling tail, and water is reached by drilling rod
Drill bit guarantees the working performance of drill bit.Existing handheld pneumatic roof-bolter into drilling tail after filling the water, due to drilling rod and drilling tail
There is certain gap in junction, and water supply has certain hydraulic pressure, and the water splashes of leakage drench the clothes of staff
It is wet, reduce comfort.
Utility model content：
The purpose of this utility model is to provide a kind of leak splashes that can be avoided drilling rod and drilling tail junction
Roof-bolter drilling tail baffle device for water.
The utility model is implemented by following technical solution：Roof-bolter drilling tail baffle device for water comprising cylindric sheath, institute
It states the outer diameter of the internal diameter and drilling tail of sheath one end close to drilling rod one end to match, is bolted with ring in the inside of the sheath other end
The axis of shape baffle, the axis of the ring baffle and the sheath is on same straight line.
Further, tubaeform deflector, the necking end of the deflector and the ring are equipped with inside the sheath
The inner annular edge of shape baffle is fixedly connected, and the flared end of the deflector is contacted with the inner wall of the sheath.
Further, it is equipped with resistance to mill tube in the sheath internal activity, the outer wall of the resistance to mill tube is interior with the sheath
Wall fitting.
The advantages of the utility model：1, it after the utility model is installed in drilling tail end, splashes so that the water leaked out is dissipated by four
Become spraying from the centre bore of ring baffle, avoids the clothes for spattering staff with water, improve work comfort；2, in sheath
Inside is equipped with tubaeform deflector, and leak can be moved along deflector to be sprayed from the centre bore of ring baffle, avoids directly
Impact ring baffle causes ring baffle to be worn；3, it is movably equipped with resistance to mill tube in sheath, prevents jacket inner wall from being leaked for a long time
Water projection abrasion, extends the service life of sheath, resistance to mill tube is replaceable, easy to use.
Detailed description of the invention：
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 uses schematic diagram for the utility model.
Sheath 1, ring baffle 2, deflector 3, resistance to mill tube 4, drilling tail 5.
Specific embodiment：
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Embodiment 1：
As shown in Figs. 1-2, roof-bolter drilling tail baffle device for water comprising cylindric sheath 1, the internal diameter of 1 one end of sheath with
Outer diameter of the drilling tail 5 close to drilling rod one end matches, and is bolted with ring baffle 2 in the inside of 1 other end of sheath, ring baffle 2
The axis of axis and sheath 1 is on same straight line；Tubaeform deflector 3, the necking of deflector 3 are equipped with inside sheath 1
End is fixedly connected with the inner annular edge of ring baffle 2, and the flared end of deflector 3 is contacted with the inner wall of sheath 1；Inside sheath 1
It is also movably equipped with resistance to mill tube 4, the outer wall of resistance to mill tube 4 is bonded with the inner wall of sheath 1.
Working principle：
One end outer wall by one end inner wall of sheath 1 and drilling tail 5 close to drilling rod welds, and after filling the water in drilling tail 5, water is from drilling tail
5 leak out with the junction of drilling rod, and leak splashes on resistance to mill tube 4, avoids leak and directly contact with 1 inner wall of sheath in sheath 1
Wall causes to wear, and extends the service life of sheath 1；Resistance to mill tube 4 can unload ring baffle 2 after damaging from sheath 1, will damage
Bad resistance to mill tube 4 is taken out from sheath 1, the resistance to mill tube 4 more renewed, then ring baffle 2 is screwed onto sheath 1, and replacement is convenient.
Leak is moved along resistance to mill tube 4 to deflector 3 after leak is splashed on resistance to mill tube 4, and avoiding directly impact ring baffle 2 leads to ring
Shape baffle 2 is worn, and leak is finally flowed out from the centre bore of ring baffle 2, avoids the clothing that splashes spatter staff with water
Clothes, improve the work comfort of staff.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
