The output shaft of the stirring motor 203 rotates through the reducer 204 to drive the stirring shaft 205 to rotate in the inner cavity of the mixing tank 201. When the stirring shaft 205 rotates, it drives the stirring rod 206 to rotate, so that the grouting liquid can be mixed and stirred to make it mixed evenly.

[0038] When in use, the output shaft of the stirring motor 203 rotates through the reducer 204 to drive the stirring shaft 205 to rotate in the inner cavity of the mixing tank 201. When the stirring shaft 205 rotates, it drives the stirring rod 206 to rotate, so that the grouting liquid can be mixed and stirred to make it mixed evenly. The output shaft of the driving motor 401 rotates to drive the driving wheel 402 to rotate. When the driving wheel 402 rotates, it drives the driven wheel 403 to rotate through the belt. When the driven wheel 403 rotates, it drives the grouting pump body 301 to run, so that the suction force generated by the grouting pump body 301 draws the grouting liquid in the inner cavity of the mixing tank 201 through the connecting pipe 302 and passes through the delivery pipe 303 is transported to the drill pipe and injected into the well through the drill pipe and drill bit. The delivery pressure and flow of the grouting liquid are monitored in real time by the remote pressure gauge 502, the inlet flow probe 508 and the outlet flow probe 509. When the pressure is too high and the delivery flow is too low, it is judged that a blockage occurs in the well. The PLC control box 501 controls the outlet solenoid valve 507 to open and relieve the pressure. At the same time of pressure relief, the PLC control box 501 turns off the drive motor 401 and the outlet solenoid valve 507, so that the grouting delivery can be stopped in time. The buffer box 503 and the pulse damper 504 can buffer the pressure to prevent damage to the equipment caused by excessive pressure.
