Description
Technical field
The utility model relates to a kind of airspace devices for deep hole blasting powder charge, belong to blasting engineering auxiliary device
Technical field.
Background technique
Drillhole blasting is the common technology of rock excavation, is widely used in the fields such as water conservancy and hydropower, mine, traffic.Tradition
Continuous cylindrical charge that there are unit consumption is big, detonation first pressing is excessively high, the overground disadvantage of rock so that the energy efficient benefit of explosive
It is low with rate, and it is also easy to produce bulk and foundation, bring the problems such as blasting vibration harm.Air-decking technique can reduce
Explosive makes blast pressure in hole axially be distributed more evenly along blasthole, to drop the initial peak pressure of blasthole surrounding rock
Excessive crushing that is low or avoiding blasthole near region country rock expands rupture zone range, improves the effective rate of utilization of explosive blasting energy,
To reduce blasting cost, controled blasting harm.Airspace device i.e. air column and explosive, air column and stemming it
Between the spacer that is arranged to bear the weight of explosive and stemming.Currently used air-spacer is air bag, unit price height,
It is cumbersome, loading rate is reduced, blasting cost is increased.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of low in cost, easy to operate quick-fried for deep hole
The airspace device of broken powder charge, to improve loading rate, reduce blasting cost.
To solve above-mentioned technical problem the technical scheme adopted by the utility model is being used for the air of deep hole blasting powder charge
Escapement, the column casing including hopper and hollow structure, column casing top is standard-sized sheet mouth structure, and column casing side wall is circumferentially spaced
It is provided with multiple groups sliding slot, every group of sliding slot as starting point and is parallel to the axis direction of column casing and be arranged using column casing top, different groups
Between sliding slot stroke it is different；Hopper is sheathed in column casing, the corresponding hopper of one group of sliding slot, is provided at least two on the outside of hopper
Part hook, hook shape specification are adapted with sliding slot, and hopper is slided along sliding slot to sliding slot end and passes through hook
It hang on the side wall of column casing.
Further, hook is symmetrically arranged two pieces；One group of sliding slot is symmetrically arranged two pieces.
Further, feed hopper bottom is provided with circular hole compatible with detonator.
Further, hopper and column casing are PVC material.
The beneficial effects of the utility model are: column casing outer diameter is slightly less than blasthole diameter, and sliding slot stroke is according to air when implementing
Spaced loading position is determining, the good column casing of pre-production and hopper.When powder charge, first column casing is put into blasthole, then by a hopper
Along the longest sliding slot decentralization of stroke, then then powder charge refills then further along drain hopper under the long sliding slot of stroke second
Medicine, until being packed into choke material after decentralization one hopper of top layer, entire powder charge process is completed.The utility model is low in cost,
It is easy to operate, loading rate can be improved.
Detailed description of the invention

Fig. 2 is the structural schematic diagram of hopper in the utility model；
Fig. 3 is overall structure diagram when implementing in the utility model.
Marked in the figure: 1- column casing, 2- sliding slot, 3- hopper, 4- hook, 5- detonator, 6- blasthole, 7- powder charge section, 8- air
Section, 9- block section, 10- detonator.
Specific embodiment
For ease of understanding with implementation the utility model, the preferred embodiment combination attached drawing work of anthology utility model is furtherly
It is bright.
As shown in Figure 1 to Figure 3, the utility model includes the column casing 1 of hopper 3 and hollow structure, is open at the top of column casing 1
Structure, 1 side wall of column casing is circumferentially spaced to be provided with multiple groups sliding slot 2, and every group of sliding slot 2 as starting point and is put down using 1 top of column casing
Row is arranged in the axis direction of column casing 1, and 2 stroke of sliding slot between different groups is different；Hopper 3 is sheathed in column casing 1, one group of sliding slot
A 2 corresponding hoppers 3, the outside of hopper 3 are provided at least two pieces hook 4, and 4 shape specification of hook is adapted with sliding slot 2, so that
Hopper 3 can be slided to 2 end of sliding slot along sliding slot 2 and be hung on the side wall of column casing 1 by hook 4.Wherein sliding slot 2 can
It, can also be for set on the U-type groove structure of 1 inner wall of column casing for through the hatch frame of 1 side wall of column casing.
Simple and reliable for structure to make, hook 4 is symmetrically arranged two pieces；One group of sliding slot 2 is symmetrically arranged two pieces.Material
PVC material can be used in bucket 3 and column casing 1.
It is passed through from hopper for convenience of detonator 5,3 bottom of hopper is provided with circular hole compatible with detonator 5.
When implementation, 1 outer diameter of column casing is slightly less than 6 diameter of blasthole, and 2 stroke of sliding slot is determined according to underground borehole blasting position, in advance
First make column casing 1 and hopper 3.When powder charge, first column casing 1 is put into blasthole 6, it is then that a hopper 3 is longest along stroke
Sliding slot 2 is transferred, then powder charge, then further along the lower drain hopper 3 of the long sliding slot 2 of stroke second, then powder charge again, until decentralization is most
After the hopper 3 of one, upper layer, it is packed into choke material, entire powder charge process is completed.
