[0046] According to the instruction manual Figure 6 It can be seen that when the surrounding environment is not suitable for machine well operation, by setting more guide pipe heads 51 on the rotating ring sleeve 55, the water supply pipe is connected to the external water station, and then the guide pipe head 51 is used to network with the pipeline, and the external water station is used to supply water to the sprinkler equipment.
