Abstract

The invention provides a backflow anti-blocking drip irrigation system and an anti-blocking drip irrigation capillary. The system comprises a drip irrigation tape, wherein the drip irrigation tape is composed of multiple anti-blocking drip irrigation capillaries, the tail ends of the multiple anti-blocking drip irrigation capillaries communicate with a backflow pipe, and the backflow pipe communicates with a water storage tank to form a closed-loop drip irrigation system. The anti-blocking drip irrigation capillary comprises a capillary main body; water outlet drip holes are formed in the capillary main body; an energy-dissipation baffle is installed at a position on the inner wall of the capillary main body where the water outlet drip holes are located; a water inlet hole formed in the energy-dissipation baffle, and a semi-closed inclined baffle is disposed on the water inlet hole. Through increase of a water flowing rate in the capillaries of the annular drip irrigation system, sand transportation and discharge potential of the capillaries are improved and the quantity of mud and sand deposited in the capillaries is reduced. Water in the capillary main body is made to flow backwards from the water inlet hole into the energy-dissipation baffle, the quantity of mud and sand particles in a mainstream area inside the capillary and sedimentation particles on the capillary bottom entering a drip head is reduced, and the anti-blocking performance of the drip irrigation system is improved.

Description

technical field [0001] The invention belongs to the field of drip irrigation and relates to the blockage of a drip irrigation device, in particular to a backflow anti-blockage drip irrigation system and an anti-blockage drip irrigation capillary. Background technique [0002] Water resources are relatively short in the inland areas of Northwest my country, and water for agricultural irrigation is in short supply. Traditional agricultural irrigation methods are seriously wasting water resources. Drip irrigation, as a new type of irrigation method that has emerged in recent years, has the advantages of water saving, energy saving and high efficiency compared with traditional irrigation methods. Although the drip irrigation system has many of the above advantages, the drip irrigation system also has the disadvantage of being easy to block due to the small structure size of the dripper and the complex water movement law in the drip irrigation system, which seriously restricts th...
