[0002] Water conservancy drip irrigation is one of the most effective water-saving irrigation methods in arid and water-scarce areas. It uses a pipeline system to transport irrigation water to the vicinity of the crop roots, and slowly drips the water into the root zone soil layer through drip heads, achieving the optimal moisture state for crop growth with the least amount of water.

[0003] Currently, during the process of water conservancy drip irrigation, rivers are usually used as the water source for drip irrigation. The river water is diverted into the pipeline system and the crops are irrigated through drip heads. However, the river water is likely to contain solid impurities, organic substances, microorganisms, etc. These substances may cause blockage inside the water-dropping openings of the drip heads. Once blockage occurs, it is difficult to clean, and the drip heads need to be replaced, increasing the operation and management costs, which needs to be improved. Content of the Utility Model:
