[0002] Drip irrigation pipe is often used in agricultural drip irrigation, and is favored by farmers due to obvious water-saving type. A general drip irrigation pipe is connected with a drip irrigation pipe through a branch pipe, so that the drip irrigation pipe extends into each drip irrigation area. An embedded drip irrigation pipe and a strip drip irrigation pipe are generally installed on the drip irrigation pipe. In order to prevent clogging, the existing technical solution filters sandstone through a dripper. However, no filter structure is added to the drip irrigation pipe, which undoubtedly increases the risk of dripper clogging.
