[0002] Road greening is an indispensable part of modern urban planning. It not only improves the beauty of the city, but also plays an important role in environmental protection and improving the quality of life of residents. Through scientific and reasonable road greening design, it can effectively reduce the occurrence of traffic accidents, improve driving safety, and provide pedestrians with a comfortable walking space. In order to ensure the growth of roadside plants, regular watering and irrigation are required. The water tanker moves along the road and is manually controlled for sprinkler irrigation.

The thread on the surface of the threaded control rod A102 drives the connecting pipe 1012 to slide upward through the lifting frame 104, and the irrigation and watering mechanism 4 is controlled to adjust the height, which is convenient for irrigation of greening at different heights. In the process of the connecting pipe 1012 sliding upward, the gear on the surface of the inner rotating rod 304 contacts the rack plate A303, and the inner rotating rod 304 is forced to rotate. The inner rotating rod 304 controls the threaded control rod C306 to rotate through the bevel gear assembly 305.

Then, the threaded control rod B207 is controlled to rotate. The thread on the surface of the threaded control rod B207 controls the sliding block 205 to slide through the driving plate 206. The irrigation and watering mechanism 4 slides to one side as a whole, so that the nozzle 403 slides to the top of the grass and trees, and the top of the grass and trees is evenly irrigated. The nozzle 403 on the other side can irrigate the sides and roots of the shrubs. The insert 503 slides and is inserted into the socket on one side of the fixed connecting plate 204. The rubber sealing ring 504 can provide a seal for the connection. When the water delivery rack 402 contacts the tree and is blocked, the water delivery rack 402 will rotate, and the connected rotating support rod 401 will rotate. The gear on the surface of the connected rotating support rod 401 controls the rotation of the rotating rod B507 through the drive chain 505. The top of the rotating rod B507 is fixedly connected to the pull rope 508. The pull rope 508 is pulled to pull the pull plate 510 to slide, and the auxiliary rod 509 spring contracts. When the water delivery rack 402 is separated from the tree, the water delivery rack 402 rotates to its original position for spraying.
