By arranging the liquid inlet pipe 7, under the action of the liquid inlet pipe 7, the flushing liquid extracted by the high-pressure pump can enter the inside of the liquid inlet pipe 7. The inside of the rotor disc 4 is respectively provided with a first sealing groove 8 and a second sealing groove 9. By arranging the first sealing groove 8 and the second sealing groove 9, it is convenient for the staff to place and disassemble the first sealing ring 10 and the second sealing ring 11.

[0026] The inside of the first sealing groove 8 and the second sealing groove 9 is respectively provided with the first sealing ring 10 and the second sealing ring 11. By arranging the first sealing ring 10 and the second sealing ring 11, under the action of the two sealing rings, the top of the rotor disc 4 and the bottom of the stator disc 5 can be connected tightly. The bottom of the rotor disc 4 is fixedly connected with a snap ring 12. By arranging the snap ring 12, under the action of the snap ring 12, the rotor disc 4 and the first flange disc 13 can be connected stably.

[0027] Referring to Figure 1 and Figure 2 , the bottom of the snap ring 12 is fixedly connected with the first flange disc 13. The outside of the drill rod 1 is provided with a second flange disc 14. The inside of the second flange disc 14 is provided with a positioning bolt. Under the action of the positioning bolt, the drill rod 1 and the rotor disc 4 can be connected stably, so that the drill rod 1 can drive the rotor disc 4 to rotate when rotating.

[0028] The outer side of the stator disc 5 is provided with a third flange plate 15.
