Description

Technical Field

[0001] The utility model relates to the technical field of drip irrigation, and more specifically to agricultural drip irrigation equipment. Background Art

[0002] Agricultural drip irrigation equipment is an efficient water-saving irrigation technology that delivers water directly and slowly to the soil near the roots of crops, thereby reducing evaporation losses and improving irrigation efficiency. Drip irrigation technology is particularly suitable for drought and water-stressed areas, as well as high-value crops with high requirements for water management, such as vegetables, fruits, flowers and economic trees. It can not only significantly save water resources, but also reduce soil erosion and the occurrence of pests and diseases, and improve crop quality and yield.

[0003] Existing drip irrigation equipment usually transports water to the entire irrigation system through a water pump, connects the water source and various irrigation areas through a main pipe and branch pipes, and the branch pipes further distribute the water to smaller irrigation units. The drip irrigation pipe is laid directly between the crop rows or near the roots of the plants. The drip irrigation pipe is embedded with drippers or drip holes to release water at a very slow rate to ensure that each plant can get the right amount of water.

[0004] In actual use of the prior art, drip irrigation equipment distributes water to various irrigation areas through main pipes and branch pipes. When operators pull the branch pipes to move to the irrigation site, the joints of the pipes will be pulled, resulting in looseness and leakage. Therefore, an agricultural drip irrigation equipment is proposed. Utility Model Content
