At this time, the camera 708 can monitor the spraying direction of the nozzle 701. Further, the controller 101 controls the nozzle commutation main motor 704 and the nozzle commutation sub-motor 706 to work in cooperation, so as to drive the connecting plate 705 to rotate, and at the same time drive the nozzle positioning plate 703 to rotate, so as to drive the nozzle 701 to rotate in all directions, so that the spraying direction of the nozzle 701 can be changed, so as to realize omnidirectional spraying, so as to ensure the humidity of the soil inside the greenhouse 2.
