Leakage-proof high-strength hydraulic slurry pump

The utility model relates to the technical field of slurry pumps, and discloses a leakproof high-strength hydraulic slurry pump which comprises a pump body, an input connecting pipe and an output connecting pipe, the top of the outer wall of the input connecting pipe is fixedly connected with a machine shell, and the left side and the right side of the outer wall of the machine shell are both fixedly connected with air pumps. The output end of the air pump is fixedly connected with an air injection pipe, the other end of the air injection pipe is fixedly connected to an air inlet of an air bag, and the air bag is arranged on the outer wall of the input connecting pipe. According to the utility model, under the action of the air pump, air is injected into the air bag through the air injection pipe, so that the air bag expands in the external connecting pipe, thereby playing a sealing role, and the gear is driven by the motor to rotate and is matched with the transmission of the gear ring to enable the driving
