Problems solved by technology

[0005] In some applications, such as micro-spraying projects in tea gardens, spray irrigation is required in summer and autumn, and spray defrosting is often required in winter. The existing micro-sprinklers can basically only achieve a single function, and there is no such thing as both large-flow irrigation and spraying. functional micro-sprinkler

Abstract

The invention discloses a micro sprinkler with sprinkling modes variable. The micro sprinkler comprises an atomizing nozzle, a rectifying nozzle, a connecting sleeve and a main pipeline. The connecting sleeve is connected with the main pipeline through threads. The rectifying nozzle is assembled on the inner side of the connecting sleeve through threaded connection. The atomizing nozzle is assembled on the outer side of the connecting sleeve through threaded connection. The rectifying nozzle and the atomizing nozzle are concentrically installed. The rectifying nozzle is located in the atomizing nozzle. The amplification segment of the rectifying nozzle is a gradually-shrunk conical pipe made of elastic materials. The diameter of an outlet of the rectifying nozzle changes together with working pressure. By adjusting the outlet modes of the micro sprinkler through the working pressure, switching operation between a spraying state and a far-distance large-flow sprinkling state can be achieved.

Description

technical field [0001] The invention relates to the field of fluid machinery, in particular to a micro-spray head with variable spray form. Background technique [0002] Micro-sprinkler irrigation is an advanced irrigation method. Compared with sprinkler irrigation, micro-sprinkler irrigation has the advantages of low working pressure, strong adaptability to terrain and soil, easy management, labor saving, uniform irrigation, and significant yield increase effect. Compared with drip irrigation, micro-sprinkler irrigation does not have strict water quality requirements, is not easy to block, and saves labor. The micro-sprinkler is the key equipment of the micro-sprinkler irrigation system, and the refraction type and the rotary type are the main structural forms of the micro-sprinkler. [0003] The refracting micro-sprinkler is also known as the atomizing micro-sprinkler. Usually, the water flow is sprayed from the nozzle, and when it encounters the refraction device, it is...
