Description

Anti-blocking structure of drip irrigation belt Technical Field The utility model relates to the technical field of drip irrigation belts, in particular to an anti-blocking structure of a drip irrigation belt. Background The conventional drip irrigation pipe is usually perforated on a smooth PE pipe (the pipe wall is usually thicker, such as 0.6mm-2.0 mm), and then independent drippers are arranged on the holes at certain intervals (such as 30cm,50cm,75cm,100cm and the like), and the drippers can be of a pressure compensation type or a non-pressure compensation type, so that the conventional pressure compensation type or the non-pressure compensation type is easy to be blocked by sediment, algae or scale due to narrow flow passages, uneven irrigation and even system failure are caused, and salt crystals (especially hard water quality areas) are easy to form at the drip holes due to continuous dripping water, so that the blocking is accelerated. Therefore, there is a need to provide a new anti-clogging structure for drip irrigation tape to solve the above technical problems. Disclosure of utility model In order to solve the technical problems, the utility model provides an anti-blocking structure of a drip irrigation belt.
