Abstract

The utility model relates to a blasting cartridge for stones, which belongs to a blasting tool for mining ore especially mining the stones of granite, etc., for ornamentation. The blasting cartridge for stone comprises a tubular form outer shell which is provided with explosive powder in the interior; at least one end of the outer shell is provided with a detonating cord exposed to the outer shell; one part of the detonating cord is positioned in the outer shell and is contacted with the explosive powder; cartridge mouths at the both ends of the outer shell are sealed by damp-proof plugs. Using the utility model to mine ore has the characteristics of high work efficiency and mining quality guarantee.

Description

Blasting cartridge for stone

The utility model is a kind of stone material explosion pipe, belongs to a kind of exploitated ore, particularly exploits the blasting-tool of decorative stones such as granite.

Present decorative stones such as exploitation granite generally adopts expanding cement or directly explosive is put into the method that the stone eye accomplished fluently carries out explosion.The operating efficiency of preceding a kind of way is very low, reaches the purpose that rock is split because it need utilize cement self to expand slowly.Then a kind of method is generally scraped stone material when explosive charge, has not only caused waste, and is difficult to obtain high-quality stone material.

The purpose of this utility model is: design a kind of stone material explosion pipe that can improve exploitation rate and guarantee the exploitation quality.

The utility model comprises that inside is equipped with the tubular shell of blast medicine, and at least one end of shell has the primacord that exposes shell, and the part of primacord is positioned at shell and contacts with the medicine that explodes, and the mouth of pipe at shell two ends is sealed by Dampproof stopper.In use with this product with the novel stone eye of having accomplished fluently of putting into, when the stone eye is dark, can adopt two ends all to have the utility model of primacord, and two adjacent primacords contact, so that ignite mutually.Through the stone material of the utility model explosion, split along the direction of stone eye, thereby guaranteed its integrality.For the way of using expanding cement, it has also improved exploitation rate greatly.Be preferably in the shell of the present utility model outside and be with at least one bumper ring.The utility model of putting into the stone eye like this can be positioned at the central authorities of stone eye under the effect of bumper ring, stressed evenly to guarantee the explosion time all directions, thereby further guarantees the complete of gained stone material, cuts the waste as far as possible.Each individuality of the present utility model all can directly adopt a primacord, and it enters from an end of shell, through its inside, is passed by the other end.At least one end of shell is with tube connector, and the internal diameter of tube connector and the external diameter of shell adapt.Tube connector is used for two even a plurality of the utility model are linked together, and to adapt to darker stone eye, it is erected in the stone eye, and with two adjacent primacords overlap joints.When not using, should on exposing the termination of shell, primacord cover moistureproof cap.

Below in conjunction with accompanying drawing the utility model is elaborated.

Fig. 1 is a phantom of the present utility model;

The of the present utility model phantom of Fig. 2 for joining by tube connector;

Wherein, the moistureproof cap of 1-, 2-primacord, 3-Dampproof stopper, the 4-medicine that explodes, 5-shell, 6-bumper ring, 7-tube connector.

As Fig. 1, the utility model is made up of shell 5, primacord 2, blast medicine 4 and bumper ring 6.Wherein, shell 5 is a long tube, and is preferably a pipe.Primacord 2 axially passes its inside along shell 5, and shell 5 is exposed at two ends.Primacord 2 exposes on the termination of shell 5 moistureproof cap 1 is housed, and in use it is taken off.Blast medicine 4 is filled between primacord 2 and shell 5 inwalls, and the mouth of pipe at the two ends of shell 5 is by Dampproof stopper 3 sealings.Be with one or several bumper ring 6 in the outside of shell 5, they are for having certain thickness annulus, and the external diameter of the internal diameter of bumper ring 6 and shell 5 adapts.In addition, as shown in Figure 2, shell 5 at least one ends of the present utility model are with and the shape of shell 5, the tube connector 7 that size matches, and it is used to connect two adjacent the utility model, will note during operation two adjacent primacord overlap joints.

Use the utility model exploitation to decorate and have high efficiency with ore, guarantee the exploitation quality, reduce the characteristics of pit wood waste.
