[0002] Farmland water-saving irrigation is to obtain greater irrigation benefits for farmland with a lower limit of water consumption, thereby greatly increasing the irrigation water volume per unit area of ​​farmland, so that the yield and output value of crops can be improved. Through farmland water-saving irrigation measures, the problem of water shortage can be alleviated, the pressure on the environment can be reduced, and the improvement of the ecological environment can be promoted. The existing public technology number CN211793415U proposes an intelligent agricultural irrigation automatic adjustment nozzle. When the water flow is sprayed from the outlet of the nozzle, the device will drive the baffle to rotate, and make the top of the baffle collide with the rubber head, so that the baffle rotates in the opposite direction, so that when the baffle rotates When the water flow sprayed by the nozzle is blocked, the radius of the nozzle spray will be changed, thereby achieving the purpose of automatically adjusting the nozzle spray range. In view of the above-mentioned related technologies, the utility model inventor believes that there are still the following defects: the self-adjusting nozzle in the comparative literature realizes automatic adjustment through the collision of the sprayed water flow with the baffle, and the irrigation range of the water flow is distributed in a fan-shaped structure along the spray direction. The irrigation range of the farmland is limited and the purpose of circular irrigation cannot be achieved. Moreover, the irrigation range of each time cannot be effectively adjusted automatically. At the same time, there is no manual adjustment method, and the adjustment is not flexible enough. In view of this, we propose a self-adjusting nozzle device for water-saving irrigation of farmland.
