Problems solved by technology
[0006] The existing widely used rectangular labyrinth channel emitter has a channel unit length of 6 mm, a channel width of 1 mm, a depth of 1 mm, and a total length of 300 mm. It is composed of 50 channel units connected in series. The water volume is 2.0-2.9L / h. Based on this, there is a need for a flow channel structure that is difficult for the emitter to block even under the conditions of high sand content in the irrigation water, while ensuring its certain hydraulic performance and flow rate. Solve the problems of current emitters that are prone to scaling and clogging, and the pursuit of hydraulic performance and anti-clogging performance.

Abstract
The invention discloses a vortex cavity type drip irrigation emitter which comprises a water inlet, a labyrinth flow channel and a water outlet, wherein the labyrinth flow channel is composed of flow channel units formed by connecting a plurality of identical triangular channels and vortex cavities in series, the triangular channels communicate with one another, and each triangular channel is composed of a first straight channel and a second straight channel; the head end of each first straight channel communicates with the corresponding vortex cavity, and the tail end communicates with the head end of the corresponding second straight channel; the tail end of each second straight channel communicates with the vortex cavity in the corresponding flow channel unit; each vortex cavity is formed by communicating an inlet, an outlet and vortex teeth. On the basis of the hydraulic performance of an existing irrigation emitter, the flow channel width is increased by about 40%, the anti-blocking performance of the irrigation emitter is greatly improved, and the irrigation emitter is simple in structure and wide in application range.
Description
technical field [0001] The invention relates to a drip irrigation device for water conservancy irrigation, in particular to a vortex cavity type drip irrigation device for irrigation, and belongs to the technical field of water-saving irrigation. Background technique [0002] The development of science and technology in agricultural irrigation facilities, water-saving, fertilizer-saving, time-saving, labor-saving, energy-saving and other drip irrigation technologies are increasingly valued by people. Drip irrigation is a sophisticated irrigation facility and the most effective water-saving method in the world. Irrigation methods are the best and indispensable irrigation measures for the development of modern agriculture, high-efficiency and energy-saving agriculture. [0003] Existing labyrinth channel emitters and pressure compensation emitters are two commonly used emitters in drip irrigation systems, and have been widely used at home and abroad. Labyrinth channel emitters...
