Description

Technical Field

[0001] The utility model relates to the field of blasting, in particular to a water hole charging device for blasting in an open-pit mine. Background Art

[0002] At present, when there is water in the blasthole during the blasting process in open-pit mines, the general method is to put the air duct into the blasthole, use the air compressor to blow the water in the blasthole to the ground, and then charge and fill it. If there is a lot of water in the blasthole, it needs to be blown five or six times. On the one hand, if the rock structure is not good during the blowing process, the hole will be blocked, and improper handling will lead to a waste hole, leaving the foundation after blasting; on the other hand, if the rock structure of the blasthole is good, the water in the cracks of the explosive hole will be replenished after the water is blown, so that the explosives are soaked in water. When the water is deep and the waterproof performance of the explosives is not good, the explosives will sometimes fail and affect the blasting effect. Utility Model Content

[0003] The utility model aims to provide a charge charging device for blasting water holes in open-pit mines, so as to solve the above-mentioned technical deficiencies.

[0004] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: an open-pit mine blasting water hole charging device, comprising:

[0005] A drug-loading cartridge, wherein the bottom end of the drug-loading cartridge is in a closed state, and the top end of the drug-loading cartridge is in an open state;

[0006] The sinking part includes a PVC pipe and an iron block. The PVC pipe is fixedly connected to the bottom of the medicine cartridge, and the bottom of the PVC pipe is in a closed state. The side wall of the PVC pipe is provided with an inlet, and the iron block passes through the inlet and enters the internal cavity of the PVC pipe.

[0007] Preferably, the drug cartridge is made of PVC.

[0008] Preferably, the diameter of the cartridge case is 30 mm smaller than the diameter of the blast hole, and the length of the cartridge case is consistent with the depth of the blast hole.

[0009] Preferably, the iron block weighs 5 kg.

[0010] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0011] Loading explosives into a charge cartridge can avoid the influence of water on the performance of the explosives and ensure the blasting effect; inserting the charge cartridge into the blast hole can directly squeeze out the water in the blast hole, reducing the water blowing process, simplifying the construction process, avoiding the blockage and waste of holes in the existing water blowing process, and ensuring the construction quality.

[0017] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0018] The utility model provides Figure 1-2 The open-pit mine blasting water hole charging device shown is characterized by comprising:

[0019] A drug cartridge 1, wherein the bottom end of the drug cartridge 1 is in a closed state and the top end of the drug cartridge 1 is in an open state;

[0020] The sinking part 2 includes a PVC pipe 21 and an iron block 22. The PVC pipe 21 is fixedly connected to the bottom of the drug cartridge 1, and the bottom of the PVC pipe 21 is in a closed state. The side wall of the PVC pipe 21 is provided with an inlet 23, and the iron block 22 passes through the inlet 23 and enters the internal cavity of the PVC pipe 21.

[0021] Furthermore, the drug cartridge 1 is made of PVC.

[0022] Furthermore, the diameter of the cartridge case 1 is 30 mm smaller than the diameter of the blast hole, and the length of the cartridge case 1 is consistent with the depth of the blast hole.

[0023] Furthermore, the iron block 22 weighs 5 kg.

[0024] Through the above technical solution:

[0025] When in use, the iron block 22 is passed through the insertion port 23 and placed in the PVC pipe 21, and then the explosive is placed in the charge cartridge 1, and then the entire device is pushed into the interior of the blast hole. During this process, since the explosive is in the charge cartridge, the water in the blast hole can be prevented from affecting the performance of the explosive, thereby ensuring the subsequent blasting effect. After the device completely enters the blast hole, the blast hole is filled for subsequent blasting operations.

[0026] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
