Embodiment
Below by embodiment, the technical solution of the utility model is described in further detail.
Embodiment 1
As shown in Figure 1, Figure 2 and Figure 3, the self-closing efficient drilling rod of a kind of spiral, including hollow drilling rod body 1, before drilling rod body 1
End is provided with pin end 2, and the rear end of drilling rod body 2 corresponds to pin end 2 and is provided with female joint 3, pin end 2 and the phase interworking of female joint 3
Close, for the docking of two drilling rods, the said equipment is the equipment being readily available for a person skilled in the art, it is not necessary to
Pay creative work.
In order to avoid during drilling rod is installed additional, the water irrigated flows back, the rear end intracavitary of drilling rod body 1 is provided with
Check valve 4, check valve 4 specifically include valve seat 41, valve element 42, spring 43 and sealing gasket 44, and the outer surface of valve seat 41 is provided with outer spiral shell
Line, the inner surface of the rear end of drilling rod body 1 correspond to the external screw thread and are provided with internal thread, and valve seat 41 passes through the external screw thread and described interior
It is threadably mounted in drilling rod body 1, convenient disassembly；Valve element 42 is set in valve seat 41, and valve element 42 can be along the axis side of valve seat 41
To slip, spring 43 is set in the rear end of valve element 42, and the rear end that the rear end of valve element 42 corresponds to spring 43 is provided with convex edge, spring 43
Top is located between the roof of valve seat 41 and the convex edge, and sealing gasket 44 is set in the front end of valve element 42；When after end pressure be more than before
During end pressure, spring 43 is compressed, and sealing gasket 44 is opened away from valve seat 41, check valve 4, when after end pressure be less than forefront pressure
When, spring 43 is stretched, and sealing gasket 44 contacts with valve seat 41, realizes sealing, and check valve 4 is closed.
In order that drilling rod is more convenient in splicing, when two drilling rods are linked together by pin end 2 and female joint 3,
Pin end 2 is pressed on the rear end of valve element 42, make thereafter end pressure be more than forefront pressure, and then check valve 4 is opened by the top of pin end 2；
After installing, except the check valve 4 of final section drilling rod is to close, the check valve 4 being above docking together is to beat
Open, can effectively anti-backflow, and can opens check valve 4 above while drilling rod is installed, installs very convenient.
It is not difficult to find out, the concrete form of check valve 4 there can be many kinds, as long as can be pushed up open by pin end 2, equal energy
Reach identical effect, the structure of check valve 4 that the present embodiment uses is more simple, and manufacturing cost is lower.
When specifically used, with deepening continuously, it is necessary to constantly access new drilling rod in the rear end of prosthomere drilling rod for drilling；
During installation, only water source need to be first disconnected, the check valve 4 in prosthomere drilling rod is closed, and effectively prevents water from flowing back, then, by new drilling rod
The female joint 3 of pin end 2 and prosthomere drilling rod is plugged in together, and the check valve 4 in prosthomere drilling rod is opened by top simultaneously, now, only
The check valve 4 of new drilling rod is closure, before drilling rod inner passage it is unimpeded, finally, water source is accessed to new drilling rod again, completes peace
Dress.
In order to facilitate row's powder, the surface of drilling rod body 1 offers twin-feed spiral groove 5；Equivalent to one powder of twin-feed spiral groove 5
The passage of discharge, while drilling rod punches downwards, caused powder can discharge out of twin-feed spiral groove 5, in addition, in drilling rod
In rotary course, the groove wall top of twin-feed spiral groove 5 serves shear action to the wall of a borehole, makes the wall of a borehole more smooth.
Installed in order to facilitate drilling rod and clamper, drilling rod body 1 is shaped as cylinder；In the prior art, cylinder bur
Bar inherently has the characteristics of easily being installed with clamper.
Preferably, the pitch of twin-feed spiral groove 5 is arranged to 50mm, the channel-section of twin-feed spiral groove 5 is arranged to radius
10mm circular arc；Now row's powder effect of twin-feed spiral groove 5 and cutting effect are relatively good.
Embodiment 2
As shown in Fig. 3, Fig. 4 and Fig. 5, the present embodiment and the difference of embodiment 1 are, the cross section of drilling rod body 1 is runway
Shape, two cambered surfaces of track type are located on same circle, and cylindrical similar with embodiment 1, it with clamper when installing
Easily；Meanwhile what is opened up on the surface of drilling rod body 1 is single thread groove 6, the pitch of single thread groove 6 is arranged to 100mm, single
The channel-section of head helicla flute 6 is arranged to radius 10mm circular arc, single thread groove 6 can effectively with the track type of drilling rod body 1
Shape cooperate, arrange powder effect and cutting effect be also fine, drilling efficiency is high.
Finally it should be noted that:Above example is only illustrating the technical solution of the utility model rather than it is limited
System；Although the utility model is described in detail with reference to preferred embodiment, those of ordinary skill in the art should
