At the same time, the water flow impacts the water wheel blades 12 to drive the movable rod frame 11 and the shunt pipe 8 to rotate, and the rotating spray head 9 is used for rotary irrigation to increase the irrigation range; Step 2: When the irrigation is about to end, start the air pump 601 to pump air into the airbag member 607 through the connecting pipe 602. The airbag member 607 expands and pushes the movable cylinder member 604 to slide outwards. The limiting rod 606 compresses the second spring 608 and closely adheres to the outer wall of the limiting ring 605. As the limiting ring 605 rotates, until the limiting hole aligns with the limiting rod 606, the second spring 608 elastically resumes and pushes the sliding piece 609 to slide, so that the limiting rod 606 is inserted into the limiting hole, stopping the rotation of the limiting ring 605 and the shunt pipe 8, limiting the shunt pipe 8, and making the spray head 9 face fixed; Step 3: After the irrigation is over, start the driving motor 503 to rotate the driving gear 504. Through the meshing of the driving gear 504 and the first rack 501, drive the sliding frame 502 and the arc-shaped frame 505 to move to the designated position. Start the general motor 507 to rotate the winding wheel 508 to relax the winding rope 509. The sliding table 512 slides under the action of gravity to the lower part of the spray head 9. Start the servo motor 520 to rotate the toothless gear 521. Through the meshing of the toothless gear 521 and the second rack 518, drive the sliding rod 516 and the connecting rod 517 to slide, drive the cleaning member 519 to insert into the spraying hole of the spray head 9 to clean the accumulated water scale. When the toothless gear 521 disengages from the second rack 518, the second spring 608 elastically resumes and pushes the sliding member 514 to drive the sliding rod 516 to reset, and reciprocate to enable the cleaning member 519 to quickly clean the spray head 9 and ensure the smoothness of the spraying hole of the spray head 9.
