Description

Technical Field

[0001] The utility model relates to the field of blasting charge hole sealing, in particular to a blasting charge hole sealing device. Background Art

[0002] The implementation process of charging includes opening charging holes, charging and sealing holes. The sealing process generally uses yellow mud to seal holes. For blastholes no larger than three meters, the sealing length is required to be greater than half a meter. This sealing process is generally completed manually with tubular tools. The sealing process has the disadvantages of loose sealing and complicated construction procedures. Specifically, the tubular tools go deep into the blastholes, and the construction process is extremely slow due to the lack of exhaust holes during the filling process. It is also easy to cause loose sealing. Multiple wooden strips need to be installed later, and there is still a problem of loose sealing. There is currently a lack of corresponding solutions to the above problems. Utility Model Content

[0003] The utility model aims to overcome the shortcomings of the prior art and provide a blasthole sealing device which has a simple structure, is suitable for a short-distance artificial blasthole sealing process and is easy to use.

[0004] The device comprises a filling tube, and the filling tube is used to fill the sealing medium;

[0005] A filling pipe is arranged at the front of the filling pipe, and the filling pipe is in the form of a round pipe as a whole, and is bent inward at the bottom of the filling pipe to form an exhaust groove outside the round pipe;

[0006] A piston system is arranged in the filling tube.

[0007] Further, the filling pipe is threadedly arranged at the front end of the filling pipe, and comprises a threaded interface portion and a pipe portion;

[0008] The pipeline part is provided with various specifications.

[0009] The effect achieved by this is that the sealing medium is filled in the filling tube, and after the filling tube is connected, the filling tube is inserted into the blasthole. The filling tube is selected so that its outer wall fits the blasthole. The medium is pushed into the blasthole by the piston system, and the filling tube is slowly retracted during the injection process. The filling medium refluxes through the exhaust groove due to the compressed air; the density of the blasthole filled at this time is greatly better than the general tool filling in the prior art. After the filling is completed, a small amount of wood strips may be inserted into the blasthole to further improve the density of the blasthole sealing.

[0010] The beneficial effects of the utility model are as follows: the utility model is different from the conventional tool sealing in the prior art, and uses a filling tube that fits the blasthole for sealing, and in particular, an exhaust groove is provided on the outer wall of the filling tube, so that the hole can be sealed smoothly, and during the sealing process, the reflux medium passes through the exhaust groove, which can further improve the sealing solidity. The equipment has a simple structure, low manufacturing and maintenance costs, and has greater safety promotion value. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The realization of the purpose, functional features and advantages of the utility model will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0019] Reference Figure 1 , Figure 2 The utility model discloses a charge hole sealing device, comprising a filling tube 3, wherein the filling tube 3 is used for filling the sealing medium;

[0020] A filling pipe is provided at the front of the filling pipe 3. The filling pipe is in the form of a round tube as a whole. The bottom of the filling pipe is bent inwards to form an exhaust groove 21 outside the round tube.

[0021] A piston system is arranged in the filling tube 3 .

[0022] Furthermore, the filling pipe 2 is threadedly arranged at the front end of the filling pipe 3, and includes a threaded interface portion and a pipe portion;

[0023] The pipeline part is provided with various specifications.

[0024] Furthermore, an elastic sealing ring 1 is fixedly provided at the front of the filling tube 2 .

[0025] Furthermore, the exhaust groove 21 protrudes forward from the filling tube 2. That is, the bending section plate protrudes forward from the filling tube 2.

[0026] Preferably, the exhaust groove 21 is an inverted U-shaped groove, and the gap between the two sides of the groove is no more than 2MM.

[0027] Furthermore, a piston plate 31 is slidably disposed inside the loading tube 3;

[0028] A slide groove is relatively opened in the filling tube 3, and the piston plate 31 includes a circular plate that fits the inner wall of the filling tube 3, and a slider connecting part that is integrally connected to the circular plate and slidably arranged in the slide groove.

[0029] Furthermore, the inner wall of the rear part of the filling tube 3 is an internal thread structure, a piston core rod 4 is threadedly provided on the filling tube 3, and a push piece is rotatably provided at the front end of the piston core rod 4.

[0030] The effect achieved by this is that by twisting the piston core rod 4, the front end push piece thereof pushes the piston plate 31 forward, thereby pushing the medium in the filling tube 3 into the filling tube 2.

[0031] Furthermore, a mounting hole is provided at the rear end of the piston core rod 4, a twisting rod 5 is passed through the mounting hole, and ball head limiters are provided at both ends of the twisting rod 5.

[0032] This prevents the twist rod 5 from being separated from the piston core rod 4.

[0033] When the utility model is used, the filling tube 3 is filled with the sealing medium, and the filling tube 2 is connected. The filling tube 2 is inserted into the blasthole, and the filling tube 2 is selected so that its outer wall fits the blasthole; the medium is pushed into the blasthole by the piston system, and the filling tube 2 is slowly withdrawn during the injection process, and the filling medium refluxes through the exhaust groove 21 due to the compressed air; the blasthole filling density completed at this time is greatly better than the general tool filling in the prior art. After the filling is completed, a small amount of wood strips may be inserted into the blasthole to further improve the blasthole sealing density.
