A dual-support rotary micro-spray head

Abstract

The invention discloses a double-part support rotary micro-sprinkler. The double-part support rotary micro-sprinkler comprises a support, a rotary body and a nozzle, wherein the support is a double-part support, a positioning hole is formed in the upper end of the support, and a sleeve is arranged at the lower end of the support; the rotary body comprises a water inlet hole, a water diversion baffle, runners and a rotary shaft which are designed in sequence from bottom to top; and the runners include the first runner and the second runner, the elevation of the first runner is larger than that of the second runner, the first runner and the second runner each have an deflection angle, and the deflection angle of the first runner is smaller than that of the second runner. The double-part support rotary micro-sprinkler has the advantages that the sprinkling radius is large, sprinkling is uniform, and the effect that in a certain pressure range, support deformation caused by high pressure does not occur, and rotation of the rotary body is not affected is achieved; the micro-sprinkler is convenient and fast to mount and dismount; due to large sprinkling width, the number of sprinklers adopted per mu on average is small, and first-time investment cost of micro-irrigation projects is reduced; and sprinkling is uniform in the sprinkling width direction, so that moisture and nutrients obtained by crops are uniform, the growing vigor is uniform, and high-yield and high-quality agricultural products can be easily achieved.

Description

technical field [0001] The invention relates to water-saving irrigation equipment, in particular to a double-support rotating micro-spray head. Background technique [0002] The distribution of water resources in my country is uneven, the efficiency of agricultural water use is low, and the average irrigation water utilization coefficient is far lower than that of developed countries. Therefore, it is very necessary to implement high-efficiency agricultural water-saving strategies and improve the level of modern agricultural irrigation technology; with the structure of agricultural planting in my country With the adjustment and improvement of farmers' economic income, the planting area of ​​economical crops and greenhouses has grown rapidly, and the requirements for water-saving irrigation are also increasing. Micro-sprinkler irrigation technology is an advanced irrigation technology that can effectively regulate crop moisture. Micro-sprinkler irrigation uses pipelines. Water ...

Problems solved by technology

[0004] In recent years, micro-sprinkler irrigation technology has been promoted on a large scale, but the spraying diameter of the existing sprinklers is not large enough and most of the spraying is uneven. In order to solve this problem, the installation distance of the sprinklers is often reduced, which makes the amount per mu more expensive. Increase

At present, driven by the wave of water-saving irrigation, Israel is currently an advanced country with water-saving equipment. my country has also conducted a large number of researches in the past ten or twenty years, forming a batch of advanced water-saving irrigation products. In research, it is an important research direction to pursue large spraying width and uniform spraying. There are also some micro sprinklers in China, but not many of them are really good in these two aspects.
