Background technology
Now, mining market is largely exploited by the way of mining explosive explosion, the big gun during exploitation
The diameter in hole progressively uses major diameter powder charge mining type with the progress of production technique, and the mining explosive selected was also from former
Powdery shape explosive to gluey emulsion transition.
But, the substantial amounts of blast hole charging means and equipment that current mining is used are to be adopted as powder type explosive to set
The compressed air hydraulic reclamation mode powder charge of meter and its equipment, above-mentioned charging means and equipment are applicable when powder type explosive is loaded, and right
Then no longer it is applicable for the filling of new gluey emulsion, loads gluey emulsion when using above-mentioned type of feed
During in major diameter blasthole, the phenomenon that gluey emulsion slides out from blasthole (uphole), influence filling often occurs
Speed, causes hidden danger.
The content of the invention
The purpose of this utility model is exactly to solve the above problems, there is provided a kind of powder charge holdback, its simple structure, is made
With convenient, it is seated in blasthole beneficial to by gluey emulsion, improves packing speed, improves the security of dynamite charge.
It is of the present utility model for gluey emulsion to be blocked in blasthole to realize above-mentioned purpose of the present utility model
Powder charge holdback include：Its front end is used for the lead segment of the gluey emulsion end being against in blasthole；Its front end with
Lead segment end connection for preventing gluey emulsion from skidding off the anti-slip section of blasthole；Wherein, the anti-slip section is conical shell,
And the big bottom of conical shell is located at its end.
Wherein, the lead segment is in cylinder.
Wherein, the front-end surface of the lead segment is plane.
Or, the front-end surface of the lead segment is the arcwall face of indent.
Wherein, the anti-slip section includes multiple expansion pawls, and multiple expansion pawls are along the circumferential equal of the lead segment end surface
Even distribution.
Wherein, the internal diameter with diameter greater than the blasthole of circumference where the multiple expansion pawl end.
Wherein, the center of the lead segment opens up the through hole passed through for the fuse for the gluey emulsion.
Wherein, the lead segment and the anti-slip section are integrally formed.
Preferably, the lead segment and the anti-slip section are molded by thermoplastic one-time-concreting.
Particularly, the lead segment and the anti-slip section are molded by polythene material or elastomeric material one-time-concreting.
Compared with prior art, powder charge holdback of the present utility model has the advantages that：
The powder charge holdback of the present embodiment, simple structure, manufacture, it is easy to use, gluey emulsion is being seated in big gun
After in hole, then powder charge holdback is packed in the end of gluey emulsion, gluey emulsion can be blocked in blasthole
It is interior, so as to solve the phenomenon that gluey emulsion is easy to be slid from blasthole because powder stick adventitia is smooth, improve dynamite charge speed
Degree and security.In addition, the powder charge holdback of the present embodiment is disposable consumption articles for use, with gluey emulsion after use
Explode and decompose, will not be polluted to environment.
The utility model is described in detail below in conjunction with the accompanying drawings.
Brief description of the drawings
Fig. 1 is the front view of the utility model embodiment powder charge holdback；
Fig. 2 is the right side view of powder charge holdback shown in Fig. 1.
Specific embodiment
As shown in Figure 1 and Figure 2, respectively the utility model embodiment for gluey emulsion to be blocked in blasthole
Powder charge holdback front view and right side view, as seen from Figure 1, Figure 2, the powder charge holdback of the present embodiment includes：Its front end
The lead segment 1 of the gluey emulsion end for being against in blasthole；Its front end be connected with the end of lead segment 1 for preventing
Only gluey emulsion skids off the anti-slip section 2 of blasthole；Wherein, anti-slip section 2 is conical shell, and the big bottom of conical shell is located at its end
End.
Specifically, as shown in Figure 1 and Figure 2, the lead segment 1 of the present embodiment powder charge holdback is in cylinder, before lead segment 1
End surfaces can use plane (not shown), it would however also be possible to employ in the arcwall face 4 (as shown in Figure 2) of indent, when in
During concave arc surface, the end of the gluey emulsion in blasthole should be using the spirogyrate table being adapted with concave curved surface
Face.
Wherein, the anti-slip section 2 of the present embodiment includes multiple expansion pawls 3, and multiple expansion pawl 3 is along the end surface of lead segment 1
Circumferentially it is uniformly distributed, and band apertured housing (the referred to as taper of taper is formed around the end surface of cylindrical lead segment 1
Shell).The front ends of multiple expansion pawls 3 are connected after can linking together with the end surface of lead segment 1, it is also possible to directly and lead segment
1 end surface is connected.
In order to gluey emulsion is blocked in into big gun after gluey emulsion is seated in uphole, using expanding pawl
In hole, during design, the internal diameter with diameter greater than blasthole of circumference where multiple expansion pawl 3 ends should be made, i.e. the big bottom position of conical shell
In the end of conical shell.
Wherein, in order to after gluey emulsion is seated in blasthole, be easy to ignite gluey emulsion, this implementation
Example opens up the through hole 5 passed through for the fuse for gluey emulsion at the center of lead segment 1.
During manufacture, the lead segment 1 and anti-slip section 2 of the present embodiment are formed using integrally formed mode, it is preferred that this implementation
The lead segment 1 and anti-slip section 2 of example are molded by thermoplastic one-time-concreting, particularly, the lead segment 1 and anti-slip section of the present embodiment
2 can be molded by polythene material one-time-concreting, or, it is molded using elastomeric material one-time-concreting, so that expansion pawl
End somewhat resilient, so that after by the present embodiment powder charge holdback plug in blasthole, the end for expanding pawl can expand outwardly,
And tight against on blasthole inwall, effectively preventing gluey emulsion from being skidded off from blasthole.
In sum, the powder charge backstop of the present embodiment is simple, manufacture, easy to use, by gluey emulsion
After being seated in blasthole, then powder charge holdback is packed in the end of gluey emulsion, gluey emulsion can be blocked up
Plug, so as to solve the phenomenon that gluey emulsion is easy to be slid from blasthole because powder stick adventitia is smooth, is improved fried in blasthole
Medicine packing speed and security.In addition, the powder charge holdback of the present embodiment is disposable consumption articles for use, with gluey breast after use
Change the blast of explosive and decompose, will not be polluted to environment.
Although being explained in detail to the utility model above, the utility model not limited to this, the skill of the art
Art personnel can modify according to principle of the present utility model, therefore, it is all according to principle of the present utility model carry out it is various
Modification all should be understood to fall into protection domain of the present utility model.
