Agricultural irrigation methods can generally be divided into traditional surface irrigation, ordinary sprinkler irrigation, and micro-irrigation. In ancient China, agricultural irrigation relied on rainfall and rivers, and farming was mainly concentrated in areas with abundant rainfall and well-developed river networks; farmers in these areas often carried out agricultural production according to the solar terms.

[0003] A search revealed an existing patent (publication number: CN222108803U) that discloses a water-saving irrigation device for farmland, including a mounting plate and connecting shells fixed at two locations on one side. It also includes a threaded rod rotating within the connecting shell's inner cavity, with a sleeve threadedly connected to the inner wall of the connecting shell. This invention, through the cooperation of a stepper motor and the threaded rod, allows the device to move freely during use, improving its effectiveness when irrigating lower areas. Furthermore, the transmission mechanism enhances the device's stability without increasing energy consumption. Simultaneously, the control mechanism allows for individual control of each nozzle, enabling the device to adapt to different ground sizes and effectively improving water-saving performance. This solves the problem of current devices being inconvenient for irrigating lower areas and having poor water-saving effects. However, this device cannot measure the amount of water sprayed; excessive water spraying on one side may lead to high soil moisture, affecting plant roots and causing root rot. Utility Model Content

Then open the second solenoid valve 305 to allow water inside the connecting pipe 304 to enter the U-shaped pipe 306, and then guide the water into the guide pipe 3 through the U-shaped pipe 306. Inside the 07 pipe, water is then introduced into the nozzle 308 through the water guide pipe 307, and sprayed out through the nozzle 308. When only one side of the pipe is needed, the second solenoid valve 305 on one side is closed, so that the water inside the outlet pipe 301 enters the U-shaped pipe 306 on the other side through the connecting pipe 304, and then the water is introduced into the water guide pipe 307 on the same side through the U-shaped pipe 306 on the other side. The water is then introduced into the nozzle 308 on that side through the water guide pipe 307 on that side, and sprayed out through the nozzle 308 on that side. The flow rate is monitored by the flow meter 303.
