[0002] The blasting water bag is also called a water stemming bag, and its function is to prevent fire and reduce dust. At present, the common way to plug holes with water stemming in underground coal mines is to first plug part of the hole with water stemming, and then plug the remaining part with solid stemming such as clay. The blasting water bags are divided into two types. One is the blasting water bag made of PVC material, and the other is the nylon composite material. The PVC material is self-sealing, and the nylon composite material has both self-sealing and non-self-sealing types. The non-self-sealing type is filled and sealed through a filling and sealing integrated machine, and the self-sealing type is filled and sealed by a water injector using water pressure.

[0003] After the primer is used up, it is necessary to confirm the hole depth, select the number of water bags to be added, and then use a tamping rod to push the water bags into the blast holes in sequence. When this step is carried out, it is easy to apply too much force, resulting in the damage or leakage of the water bags. Pushing them in sequence is time-consuming and laborious, and also increases the risk of water bag damage. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Please refer to Figures 1-4 , the present utility model provides a technical solution: an assembled water bag plugging and dust reduction device for blasting, including an outer layer 1, an inner layer 2, a connection port 3, a sealing ring 4, a pressing ring 5, an airbag one 6, an air pipe 7, an airbag two 8, a mobile interface 9, a fixing plate 10, a conical port 11, a vertical rod 12, an air column 13, a support bar 14, and a docking port 15.

[0029] Embodiment 1

[0030] The assembled water bag plugging and dust reduction device for blasting is provided with an assembling structure, and can assemble a plurality of water bags by connecting through the connection port 3 and the docking port 15. Specifically:

[0031] The upper end of the outer layer 1 is provided with an opening, and further includes an inner layer 2. The inner layer 2 is installed inside the outer layer 1. An assembly structure is installed at the upper end of the outer layer 1. The assembly structure includes a connection port 3. The connection port 3 is fixedly installed at the upper end of the outer layer 1. A slot is provided on the outer surface of the connection port 3. A pressing ring 5 is slidably installed on the outer surface of the connection port 3. A sealing ring 4 is installed on the upper surface of the connection port 3. An airbag 6 is installed on the lower surface of the slider of the pressing ring 5. The short link of the airbag 6 is provided with an air tube 7. The other end of the air tube 7 is connected to an airbag 8. The airbag 8 is installed on the lower surface of the slider of the moving interface 9. The moving interface 9 is slidably installed on the inner wall surface of the connection port 3. A fixing plate 10 is installed at the lower end of the moving interface 9. The fixing plate 10 is fixedly connected with a vertical rod 12. The upper end of the vertical rod 12 is connected with a conical port 11. The lower surface of the outer layer 1 is provided with a docking port 15. The connection port 3, the pressing ring 5 and the groove of the docking port 15 correspond to each other;

[0032] When the assembled blasting water bag plugging and dust reduction device is used, as Figure 1 shown, multiple water bags are assembled according to requirements. First, the connection port 3 and the docking port 15 of the two water bags are rotationally threadedly connected, so that the docking port 15 presses down the pressing ring 5. As Figure 4 shown, the slider of the pressing ring 5 will squeeze the airbag 6, and then the air flow in the airbag 6 will make the air flow into the airbag 8 through the air tube 7. Since the airbag 8 is installed on the lower surface of the slider of the moving interface 9, the airbag 8 will be jacked up. At this time, the moving interface 9 will be located between the connection port 3 and the connection of the docking port 15. At the same time, the sealing ring 4 installed on the upper surface of the connection port 3 will also make the connection more sealed. At the same time, the fixing plate 10 fixedly installed at the lower end of the moving interface 9 will drive the vertical rod 12 to move upward, so that the upper end of the vertical rod 12 will stack with the lower end of the vertical rod 12 in another water bag. At this time, the docking assembly is completed. Then, water is filled into the water bag through the uppermost connection port 3, so that the inner layer 2 is filled with water. Then, the water bag is inserted into the blasting hole. When inserting, the corresponding vertical rod 12 is pushed to move the water bag, so as to avoid piercing the water bag due to excessive force when using a blasting rod to push.

[0033] Embodiment 2

[0034] The assembled blasting water bag plugging and dust reduction device is also provided with an anti-breaking structure, which can avoid the outer surface of the water bag from being damaged and leaking water. Specifically:

[0035] The outer layer 1 is also connected with an anti-breaking structure. The anti-breaking structure includes air columns 13. The air columns 13 are installed on the inner wall surface of the layer 1 in a circumferential and equidistant manner. A support strip 14 is installed on the outer surface of the air column 13. The other side of the support strip 14 is attached to the outer surface of the inner layer 2. The support strip 14 is set as an elastic rubber block. The outer surface of the connection port 3 is provided with threads;

[0036] When the water bag enters the muzzle, friction is likely to occur between the outer surface of the water bag and the inner wall of the gun hole, causing the water bag to be damaged and leak. Therefore, an outer layer 1 is provided on the outside of the inner layer 2. The air column 13 on the inner wall surface of the outer layer 1 can prevent the inner wall from cracking and at the same time reduce the impact of collision. The support strip 14 installed on the outer surface of the air column 13 can limit the tension when the inner layer 2 is filled with water, enabling the water filling amount to be just right and making the blasting effect better.

[0037] Working principle: When using the assembled blasting water bag plugging and dust reduction device, an assembly structure is provided, which can connect multiple water bags through the connection port 3 and the docking port 15. An anti-break structure is provided, which can protect the inner layer 2 through the air column 13 and the support strip 14, increasing the overall practicability.

[0038] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
