Background

Agricultural irrigation mainly refers to irrigation operation performed on agricultural cultivation areas. Agricultural irrigation methods can be generally divided into traditional ground irrigation, general sprinkling irrigation and micro-irrigation. Wherein the common spray irrigation technology is a relatively common irrigation mode in Chinese agricultural production. The spray irrigation is an irrigation mode that water with certain pressure is sprayed into the air by means of a water pump and a pipeline system or by utilizing the fall of a natural water source to be dispersed into small water drops or form mist to fall onto plants and the ground. Most of the existing equipment for agricultural irrigation adopts a fixed-position spray head to perform spray irrigation operation, so that the spray head can only spray irrigation in a specific area during spray irrigation.
