[0027] When in use, place one end of the suction pipe 8 in the mud, and then start the permanent magnet motor 1 to drive the connecting shaft 3 on the surface of the fixed plate 2 to rotate, so that the sliding block 4 in the sliding frame 5 moves forward and backward, thereby causing the piston 14 in the piston tube 6 to move, driving the diaphragm 15 at one end of the piston tube 6 to expand and contract. When the diaphragm 15 expands and contracts into the tube, the rotating plate 16 at one end of the suction pipe 8 will open, allowing the mud to enter the transfer pipe 7. When the diaphragm 15 bulges outward, the rotating plate 16 in the discharge pipe 9 will open, thereby discharging the mud. The entire device has a compact structure, and the overall rectangular structure of the device is convenient for placement. The fixed handle 17 located on the surface of the protective outer frame 10 is convenient for carrying and transporting, avoiding the problem of the mud pump being inconvenient to carry due to its large size.

[0028] Example 2: Based on Example 1, in order to make the mud pump run better, a permanent magnet motor 1 is provided. The permanent magnet motor 1 is fixedly connected to the inner wall of the protective outer frame 10. A fixed handle 17 is provided on the surface of the protective outer frame 10. A transmission block is provided at one end of the permanent magnet motor 1.

[0029] A circular groove is provided on the surface of the fixing plate 2, a hole is provided on the surface of the circular groove, a fixing screw is provided in the hole, a transmission block is clamped in the circular groove, a threaded hole is provided on the surface of the transmission block, a fixing screw is screwed into the threaded hole, and a connecting rod 11 is provided on the surface of the fixing plate 2;

[0030] A circular hole is opened on the surface of the connecting shaft 3, and a fixed bearing 12 is set in the hole. A circular plate is fixedly connected to the inner ring surface of the fixed bearing 12, and a connecting rod 11 is fixedly connected to the center of the circular plate surface;

[0031] Slide blocks 18 are provided on both sides of the sliding block 4. A clamping block is provided at one end of the sliding block 4. A circular hole is provided on the surface of the clamping block. A rotating shaft 13 is provided in the circular hole. The rotating shaft 13 passes through one end of the connecting shaft 3. The connecting shaft 3 can rotate freely on the surface of the rotating shaft 13. A piston rod is provided at the other end of the sliding block 4, and a piston 14 is provided at one end of the piston rod.

[0032] A slide groove is provided on the inner wall of the sliding frame 5, and the slide groove is connected to the slider 18. A hole is provided at one end of the sliding frame 5, and a piston rod is provided in the hole. A piston tube 6 is provided at one end of the sliding frame 5, and a piston 14 is provided in the piston tube 6. A diaphragm 15 is provided at one end of the piston tube 6.

The fixing frame is installed on the inner wall of the piston tube 6, and the guide rod can move freely in the fixing frame.

[0033] In order to ensure better operation of the device, after the operator starts the permanent magnet motor 1 again, since a connecting rod 11 is provided at one end of the fixed plate 2, and one end of the connecting shaft 3 is fixed to one end of the connecting rod 11, the fixed plate 2 rotates to drive the movement of one end of the connecting shaft 3, and a sliding block 4 is provided at the other end of the connecting shaft 3. Due to the movement of the connecting shaft 3, the sliding block 4 is driven to move back and forth in the sliding frame 5, so that the piston 14 connected to the sliding block 4 through the piston rod reciprocates in the piston tube 6, causing the diaphragm 15 at one end of the piston tube 6 to bulge and contract. When the diaphragm 15 contracts, the suction force will open the rotating plate 16 at one end of the suction pipe 8 and close the rotating plate 16 at one end of the discharge pipe 9, thereby transporting the mud to the transfer pipe 7. When the diaphragm 15 bulges, the rotating plate 16 at one end of the discharge pipe 9 opens, and the rotating plate 16 at one end of the suction pipe 8 closes to prevent the mud from flowing back, thereby discharging the mud in the transfer pipe 7, so that the device can better achieve the expected effect.

[0035] In order to prevent larger objects from entering the device and damaging the equipment, a filter plate is provided at one end of the suction pipe 8 to isolate larger objects from the outside.

[0036] During actual use, one end of the suction pipe 8 is placed in the mud, and then the permanent magnet motor 1 is started to drive the connecting shaft 3 on the surface of the fixed plate 2 to rotate, so that the sliding block 4 in the sliding frame 5 is displaced forward and backward, thereby displacing the piston 14 in the piston tube 6, driving the diaphragm 15 at one end of the piston tube 6 to expand and contract. When the diaphragm 15 expands and contracts into the tube, the rotating plate 16 at one end of the suction pipe 8 will open, allowing the mud to enter the transfer pipe 7. When the diaphragm 15 bulges outward, the rotating plate 16 in the discharge pipe 9 will open, thereby discharging the mud. The entire device has a compact structure, and the overall device is a rectangular structure for easy placement. The fixed handle 17 located on the surface of the protective outer frame 10 is easy to carry and transport, avoiding the problem of the mud pump being inconvenient to carry due to its large size.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
