[0033] The surface of the support tube 7 is sleeved with a torsion spring 12, which can be fixed with the fixing plate 13, so that the support tube 7 is rotated and twisted to reset the fixed gear 11. The top of the surface of the support tube 7 is fixedly connected with the fixing plate 13, one end of the torsion spring 12 is fixedly connected with the bottom of the fixing plate 13, and the other end of the torsion spring 12 is fixedly connected with the top of the stabilizing plate 8.

[0037] Specifically, the sealing ring 20 can continuously rub against the inner wall of the support tube 7, so that the spray tube 14 is not easy to move down after moving up, and can fix the humidification height of the atomizing nozzle 16 on the surface of the spray box 15 after being pulled up during use, so that it is not easy to move down; the support ring 21 can support the sealing ring 20, so that the sealing ring 20 can stably make frictional contact with the inner wall of the support tube 7 after being supported, and after the support ring 21 is limited by the limiting rod 22, it can effectively ensure that the spray tube 14 connected to the limiting rod 22 can follow the support tube 7 for rotation adjustment during rotation, and the reinforcement ring 23 can seal the movable gap between the spray tube 14 and the support tube 7, so that the water source is not easy to overflow from the gap between the support tube 7 and the spray tube 14.

[0038] Working principle: The water pump 6 extracts water from the inside of the water tank 2 and transports it into the inside of the support tube 7. The water source is transported into the inside of the spray box 15 through the connection between the support tube 7 and the spray pipe 14, and then sprayed from multiple atomizing nozzles 16, so that the multiple atomizing nozzles 16 atomize the water source and spray it to humidify the fruit trees in the greenhouse to adjust the humidity. After the stepper motor 9 drives the half gear 10 to rotate, the half gear 10 rotates the support tube 7 through the meshing with the fixed gear 11, so that the support tube 7 passes through the limit The rod 22 is limited by the support ring 21 on the surface of the spray pipe 14, so that the support pipe 7 is rotated by the fixed gear 11 to adjust the spray range of the spray pipe 14, the spray box 15 and the multiple atomizing nozzles 16, so that the atomizing nozzles 16 can adjust the humidity of different areas in the greenhouse after the rotation adjustment, thereby improving the efficiency of humidity adjustment in the greenhouse. In addition, after the rotation axis of the support pipe 7 rotates the fixed plate 13, the fixed plate 13 twists the torsion spring 12 fixed to the stabilizing plate 8, so that the support pipe 7 is subjected to rotation. The continuous torsion force of the torsion spring 12 can make the support tube 7 drive the spray tube 14, the spray box 15 and the atomizing nozzle 16 to rotate after the half gear 10 is separated from the surface of the fixed gear 11, so that the atomizing nozzle 16 can adjust the humidity of the fruit trees in the greenhouse in a fan shape, so that the spray box 15 and the atomizing nozzle 16 can swing back and forth in a fan shape during the continuous rotation of the stepping motor 19 to adjust the humidity of the fruit trees in the greenhouse over a large area, thereby achieving humidification of a large area of ​​different areas in the greenhouse during humidity regulation, thereby improving the humidity regulation efficiency of the fruit trees in the greenhouse, and when it is necessary to move the base 1 to move the humidification area in an unmanned environment, first start the stepping motor 2 17 to rotate the stabilizing gear 19, so that the stabilizing gear 19 drives the roller 3 and the wheel 4 to rotate through the meshing of the transmission gear 18, and move the base 1, so as to adjust the atomizing nozzle 16 to move in the greenhouse when the base 1 is pushed by nobody to adjust the humidification area, thereby achieving the convenience of moving and adjusting the humidification area in an unmanned environment.
