[0002] ‌Coal mining is an activity in which humans extract coal resources in coal-rich mining areas.‌ It is mainly divided into two mining methods: underground coal mines and open-pit coal mines.‌ Underground coal mines are suitable for the situation where the coal seam is far from the surface.‌ By digging tunnels underground to extract coal, when working in the mine, it is necessary to carry out grouting consolidation and mine support work, etc. Usually, a mine pneumatic liquid injection pump is used to assist the operation;

[0003] For the existing mine pneumatic liquid injection pump, compressed air enters the cylinder,‌ pushing the cylinder piston to reciprocate.‌ Since the cylinder pull rod is connected to the slurry cylinder pull rod,‌ the reciprocating motion of the cylinder piston also drives the slurry cylinder piston to reciprocate,‌ thereby completing the suction and discharge slurry actions and completing the liquid pressurized pumping;

[0004] The slurry cylinders of the existing mine pneumatic liquid injection pumps are all connected to the conveying pipeline through fastening screws and flange plates. When cleaning, maintaining or replacing the slurry cylinder, the disassembly process is cumbersome, which takes a lot of time and affects the work efficiency. For this reason, we propose a mine pneumatic liquid injection pump. Content of the Utility Model

[0008] Further, a cylinder is fixedly connected inside the housing. A piston is slidably connected inside the T-shaped slurry cylinder. The rear end of the piston rod of the cylinder is fixedly connected to the front end of the piston to provide power for pumping liquid.

[0009] Further, spherical one-way valves are fixedly connected to the ends of the clamping pipes away from the T-shaped slurry cylinder. The left end of the spherical one-way valve on the left is fixedly connected to an infusion pipe to control the liquid to enter the T-shaped slurry cylinder.

[0010] Further, a liquid storage tank is fixedly connected to the upper side inside the housing. The infusion pipe is communicated with the lower surface of the liquid storage tank to store the slurry.

[0011] Further, a liquid inlet is fixedly connected to the upper surface of the housing. A spherical valve is fixedly connected inside the liquid inlet. The lower end of the liquid inlet is communicated with the liquid storage tank to enable the slurry to enter the pump body.

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

[0021] Please refer to Figures 1-3 , this embodiment provides a technical solution: a mine pneumatic liquid injection pump, including a housing 1, symmetrically distributed handles 4 are fixedly connected to the upper surface of the housing 1, a T-shaped slurry cylinder 11 is fixedly connected to the lower surface inside the housing 1 by bolts, uniformly distributed support rods 2 are fixedly connected to the lower surface of the housing 1, a support block 3 is fixedly connected to the lower surface of each of two longitudinally adjacent support rods 2, and further includes a pipeline connection mechanism 8;

[0022] Pipeline connection mechanism 8: It includes an elastic snap ring 81, a clamping pipe 82 and a rubber gasket 83. The elastic snap ring 81 is slidably connected to the left and right ends inside the T-shaped pulp cylinder 11. The inner surface of the elastic snap ring 81 is provided with uniformly distributed inclined tooth grooves. Rubber gaskets 83 are fixedly connected to the left and right ends inside the T-shaped pulp cylinder 11. Clamping pipes 82 are clamped to the left and right ends inside the T-shaped pulp cylinder 11. When maintaining the mine pneumatic liquid injection pump, press the elastic snap ring 81 towards the middle of the T-shaped pulp cylinder 11. The elastic snap ring 81 moves towards the inside of the T-shaped pulp cylinder 11. At this time, pull out the clamping pipe 82 in the direction away from the T-shaped pulp cylinder 11 to complete the disassembly of the T-shaped pulp cylinder 11. After cleaning and maintaining its interior, insert the clamping pipe 82 into the T-shaped pulp cylinder 11. At this time, pull the elastic snap ring 81 in the direction away from the inside of the T-shaped pulp cylinder 11 to make the elastic snap ring 81 clamped between the T-shaped pulp cylinder 11 and the clamping pipe 82 to complete the installation of the clamping pipe 82. A cylinder 9 is fixedly connected inside the housing 1. A piston 10 is slidably connected inside the T-shaped pulp cylinder 11. The rear end of the piston rod of the cylinder 9 is fixedly connected to the front end of the piston 10. Spherical one-way valves 14 are fixedly connected to the ends of the clamping pipe 82 away from the T-shaped pulp cylinder 11. The left end of the left spherical one-way valve 14 is fixedly connected to an infusion pipe 13. A liquid storage tank 12 is fixedly connected to the upper side inside the housing 1. The infusion pipe 13 is communicated with the lower surface of the liquid storage tank 12. A liquid inlet 7 is fixedly connected to the upper surface of the housing 1. A spherical valve 6 is fixedly connected inside the liquid inlet 7. The lower end of the liquid inlet 7 is communicated with the liquid storage tank 12. A liquid outlet 5 is fixedly connected to the right surface of the housing 1. A spherical valve 6 is also fixedly connected inside the liquid outlet 5. The liquid outlet 5 is communicated with the right end of the right spherical one-way valve 14. When using this mine pneumatic liquid injection pump for liquid injection, install an external infusion pipe on the liquid inlet 7 and install an external liquid outlet pipe on the liquid outlet 5. At this time, control the external cylinder to start the cylinder 9 to make the piston rod of the cylinder 9 reciprocate back and forth, and open the two spherical valves 6. The external liquid enters the liquid storage tank 12 through the liquid inlet, flows through the infusion pipe 13, and enters the T-shaped pulp cylinder 11 through the left spherical one-way valve 14. The piston rod of the cylinder 9 reciprocates back and forth to drive the piston 10 inside the T-shaped pulp cylinder 11 to move back and forth. When the piston 10 moves forward, the pressure inside the T-shaped pulp cylinder 11 increases, and the liquid pressure inside the T-shaped pulp cylinder 11 increases. At this time, the left spherical one-way valve 14 closes, and the right spherical one-way valve 14 opens. The pressurized liquid flows out from the right side of the T-shaped pulp cylinder and is discharged through the liquid outlet 5. When the piston 10 moves backward, the pressure inside the T-shaped pipe 11 decreases, the right spherical one-way valve 14 closes, and the left spherical one-way valve 14 opens to allow the liquid to flow into the T-shaped pulp cylinder 11. In this way, it circulates repeatedly to pressurize and pump the liquid.

[0023] The working principle of a mine pneumatic liquid injection pump provided by the present utility model is as follows: When using this mine pneumatic liquid injection pump for liquid injection, an external liquid delivery pipe is installed on the liquid inlet 7, and an external liquid outlet pipe is installed on the liquid outlet 5. At this time, control the external cylinder and start the cylinder 9 to make the piston rod of the cylinder 9 reciprocate back and forth, opening the two spherical valves 6. The external liquid enters the liquid storage tank 12 through the liquid inlet, flows through the liquid delivery pipe 13, and enters the T-shaped slurry cylinder 11 through the spherical one-way valve 14 on the left. The piston rod of the cylinder 9 reciprocates back and forth to drive the piston 10 inside the T-shaped slurry cylinder 11 to move back and forth. When the piston 10 moves forward, the pressure inside the T-shaped slurry cylinder 11 increases, and the liquid pressure inside the T-shaped slurry cylinder 11 increases. At this time, the spherical one-way valve 14 on the left closes, and the spherical one-way valve 14 on the right opens. The pressurized liquid flows out from the right side of the T-shaped slurry cylinder and is discharged through the liquid outlet 5. When the piston 10 moves backward, the pressure inside the T-shaped pipe 11 decreases, the spherical one-way valve 14 on the right closes, and the spherical one-way valve 14 on the left opens, allowing the liquid to flow into the T-shaped slurry cylinder 11. This cycle repeats to pressurize and pump the liquid. When maintaining the mine pneumatic liquid injection pump, press the elastic snap ring 81 towards the middle of the T-shaped slurry cylinder 11. The elastic snap ring 81 moves towards the inside of the T-shaped slurry cylinder 11. At this time, pull out the clamping pipe 82 away from the T-shaped slurry cylinder 11 to complete the disassembly of the T-shaped slurry cylinder 11. After cleaning and maintaining its interior, insert the clamping pipe 82 into the T-shaped slurry cylinder 11. At this time, pull the elastic snap ring 81 away from the inside of the T-shaped slurry cylinder 11 to make the elastic snap ring 81 snap between the T-shaped slurry cylinder 11 and the clamping pipe 82 to complete the installation of the clamping pipe 82.

[0024] It should be noted that in the above embodiments, the spherical valve 6 disclosed is a Q11F-16P two-piece ball valve, and the spherical one-way valve 14 is an HQ44X spherical one-way check valve.

[0025] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made using the description and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall equally be included within the patent protection scope of the present utility model.
