Description
Technical field
The utility model is related to demolition set technical field, more particularly to a kind of Uncoincided charge explosive cartridge.
Background technology
Explosive diameter is less than blasthole diameter, and there are the charging means in gap not to couple dress referred to as between explosive and blasthole wall
Medicine.
The ratio of blasthole diameter and cartridge size is known as the not coefficient of coup.Its value size and medium, explosive characteristic etc. are related.
Since there are gaps for pack surrounding, the peak pressure of explosion is reduced, is made to reduce or avoid excessive crushed rock and detonation pressure
With when increase, improve blasting energy utilization rate.
However existing Uncoincided charge explosive cartridge, powder charge is difficult, and air-decking ratio is unreasonable, and demolition effect is bad.
Utility model content
The utility model provides a kind of Uncoincided charge explosive cartridge, can solve the above problem in the prior art.
The utility model provides a kind of Uncoincided charge explosive cartridge, including：Housing bucket, inner sleeve bucket, limiting slot and taper
Sleeve is blocked, housing bucket and inner sleeve bucket are column barrel, and limiting slot is coaxially fixed on the bottom of housing bucket, and the setting of inner sleeve bucket exists
In housing bucket, the bottom of inner sleeve bucket is arranged in limiting slot, is uniformly provided with multiple through-holes on inner sleeve bucket, under cone blocking sleeve
Portion is spirally connected by the upper end sealing of screw thread and sealing ring and housing bucket, and the top of cone blocking sleeve is equipped with blasthole, blasthole aperture
Less than the diameter of inner sleeve bucket, the diameter ratio of housing bucket and inner sleeve bucket is 7.4: 10.
Further, the bur that multiple outer ends carry crotch is also fixed on the lateral surface of the housing bucket.
Further, the housing bucket and inner sleeve bucket are PVC material.
Compared with prior art, the beneficial effects of the utility model are：
For the utility model by being packed into explosive in the inner sleeve bucket equipped with multiple through-holes, powder charge is simple and convenient, passes through limit
Slot makes housing bucket coaxially be fixed with inner sleeve bucket, make not coupled room be uniformly distributed around explosive, while housing bucket and inner sleeve
The diameter ratio of bucket is 7.4: 10 so that the ratio of housing atmosphere in the tub layer basically reaches 45%, and the coefficient of coup does not reach 1.81, quick-fried
Broken effect is good.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of Uncoincided charge explosive cartridge provided by the utility model.
Reference sign：
1- housing buckets, 2- inner sleeve buckets, 3- limiting slots, 4- cone blocking sleeves, 5- burs.
Specific implementation mode
Below in conjunction with the accompanying drawings, a specific implementation mode of the utility model is described in detail, it is to be understood that this
The protection domain of utility model is not restricted by specific implementation.
As shown in Figure 1, a kind of Uncoincided charge explosive cartridge that the utility model embodiment provides, including：It is housing bucket 1, interior
Bucket 2, limiting slot 3 and cone blocking sleeve 4 are covered, housing bucket 1 and inner sleeve bucket 2 are column barrel, and limiting slot 3 is coaxially fixed on outer
The bottom of bucket 1 is covered, inner sleeve bucket 2 is arranged in housing bucket 1, and the bottom of inner sleeve bucket 2 is arranged in limiting slot 3, on inner sleeve bucket 2 uniformly
Equipped with multiple through-holes, the lower part of cone blocking sleeve 4 is spirally connected by the upper end sealing of screw thread and sealing ring and housing bucket 1, taper
The top for blocking sleeve 4 is equipped with blasthole, and blasthole aperture is less than the diameter of inner sleeve bucket 2, and housing bucket 1 and the diameter ratio of inner sleeve bucket 2 are
7.4∶10。
The course of work and principle：Explosive will be filled in inner sleeve bucket 2, detonator is embedded in explosive, and inner sleeve bucket 2 is placed on housing
In the limiting slot 3 of 1 bottom of bucket, tamper being filled up in cone blocking sleeve 4, the detonator wire being connect with detonator is pierced by blasthole,
The upper end sealing of the cone blocking sleeve 4 for filling up tamper and housing bucket 1 is spirally connected, the tamper is soft clay.
When weakening force of explosion, can in the inner sleeve bucket 2 a small amount of explosive of filling, be located at the inner sleeve bucket 2 on explosive top with it is outer
Tamper is filled in set bucket 1.
The bottom that limiting slot 3 is coaxially fixed on housing bucket 1 makes inner sleeve bucket 2 and housing bucket 1 coaxial, while blasthole aperture is small
In the diameter of inner sleeve bucket 2, plasting damage effect and effect are improved.
The lower part of cone blocking sleeve 4 is spirally connected by the upper end sealing of screw thread and sealing ring and housing bucket 1, and powder charge is convenient,
It is easy to use.
By the filling explosive in the inner sleeve bucket 2 equipped with multiple through-holes, explosive is fixed, and and air insulated, outside
The diameter ratio for covering bucket 1 and inner sleeve bucket 2 is 7.4: 10 so that the ratio of air layer reaches 45% in housing bucket 1, and the coefficient of coup does not reach
To 1.81, demolition effect is best.
Further, as shown in Figure 1, being also fixed with multiple outer ends on the lateral surface of the housing bucket 1 carries crotch
Hangnail 5.
For multiple hangnails 5 convenient for the fixation of explosive cartridge and surrounding rock or soil layer, the outer end of multiple hangnails 5 carries crotch, more
A hangnail 5 is integrally formed with housing bucket 1, is avoided because of explosive cartridge outer smooth, and locating effect is bad, to influence explosion effect
Fruit.
Further, the housing bucket 1 and inner sleeve bucket 2 are PVC material.
PVC material reduces blasting cost.
For the utility model by being packed into explosive in the inner sleeve bucket equipped with multiple through-holes, powder charge is simple and convenient, passes through limit
Slot makes housing bucket coaxially be fixed with inner sleeve bucket, make not coupled room be uniformly distributed around explosive, while housing bucket and inner sleeve
The diameter ratio of bucket is 7.4: 10 so that the ratio of housing atmosphere in the tub layer basically reaches 45%, and the coefficient of coup does not reach 1.81, quick-fried
Broken effect is good.
Disclosed above is only several specific embodiments of the utility model, and still, the utility model embodiment is not office
It is limited to this, the changes that any person skilled in the art can think of should all fall into the scope of protection of the utility model.
