[0002] The key to normal crop growth and high and stable yields lies in adequate water supply. However, under natural conditions, since precipitation often cannot meet the water needs of crops, people need artificial irrigation to supplement the lack of natural rainfall.

[0003] In current irrigation practices, natural water bodies such as river water, lake water and pond water are often used as irrigation water sources. However, these water bodies usually contain a large amount of impurities, which can cause wear and blockage on the pipes and nozzles of irrigation equipment, reducing irrigation efficiency. In order to address this problem, some existing irrigation equipment is equipped with filters for filtering impurities. These filters can intercept impurities in the water to a certain extent and protect the irrigation equipment from damage.
