[0041] Working principle: During installation, two plug connectors 602 are connected to the water guide hose and the fertilizer guide hose respectively, and multiple guide rails 105 are connected and laid in sequence along the top of the large screen;

[0042] When traveling, the traveling motor 103 is started, and the traveling motor 103 drives the traveling wheel 104 to roll along the surface of the guide rail 105 to achieve traveling, and the lateral position adjustment of the device can be achieved by driving the hanging plate 201 through the linear motor 101;

When winding, the protective shell 301 rises, and when unwinding, the protective shell 301 falls, so that the camera 306 and the threaded head 708 are lifted and lowered to the designated position for watering, fertilizing and close-range detection;

[0044] When fertilizing or sprinkling water, firstly, the alignment electromagnet 604 is energized, and then the winding motor 208 is started to raise the protective shell 301. When the protective shell 301 rises to the vicinity of the alignment electromagnet 604, the alignment electromagnet 604 attracts the alignment iron rod 505 to gradually align. As the protective shell 301 rises, the plug connector 602 is inserted into the feeding guide seat 501. At the same time, the alignment electromagnet 604 attracts and fixes the alignment iron rod 505, and then opens the electromagnetic valve 603 to add water or fertilizer, so that water or fertilizer liquid is stored in the water tank 401 until the springtails in the water tank 401 reach a certain position, close the electromagnetic valve 603, and then close the electromagnetic valve 603. Close the positioning electromagnet 604, start the winding motor 208 to lower the protective shell 301, when watering, lower the threaded head 708 to the top of the plant to spray the plant leaves, when fertilizing, lower the threaded head 708 to the top of the plant root system to spray the root system to prevent the plant leaves from being burned, when spraying, start the air pump 706, the air pump 706 continuously sprays air, and the air flow is ejected downward at a high speed from the jet pipe 705. When spraying, the high-speed airflow generates a negative pressure area, so that the liquid inside the cover tube 701 passes through the guide hole 704 into the guide pipe 703, and then mixes with the gas and is ejected from the guide nozzle 709, thereby achieving spraying.
