Non-rotating extensible variable sprayer

Abstract

The invention belongs to a key device in a water-saving irrigation sprinkling system, particularly relates to a non-rotating extensible variable sprayer and aims to solving the key technical problems that the energy consumption is high, the operation is unstable, and a single spray head can not spray arbitrary shapes of variables. The non-rotating extensible variable sprayer comprises an outer shell connecting seat, a spring, a spray body, a nozzle, a limiting ring, a cover plate and a rubber ring. Before the non-rotating extensible variable sprayer works, the limiting ring 5 is regulated according to the shapes of application land blocks to lead each nozzle 4 to reach a range needed by the land blocks. When the non-rotating extensible variable sprayer works, the spray body is rushed by water current to overcome resistance generated by the spring and the rubber ring, and the spray body is moved upwards to lead the nozzle to expose the outer shell connecting seat, thereby realizing the variable domain spray of arbitrary shapes, including a sector. The invention has the advantages of simple structure, low energy consumption and reliable operation and can realize domain spray in arbitrary shapes.

Description

technical field [0001] The invention belongs to key equipment in a water-saving irrigation sprinkler irrigation system, in particular to a non-rotating scalable variable-variable sprinkler. Background technique [0002] The 21st century will be an era of rapid social and economic development in our country, and an era of unprecedentedly sharp contradictions between supply and demand of water resources. Vigorously developing water-saving irrigation is the fundamental way to solve the shortage of agricultural water in our country. The sprinkler is the key equipment that affects the irrigation quality of the sprinkler irrigation system. With the development trend of sprinkler irrigation equipment towards low energy consumption and precise irrigation, variable spraying has become an important precise spraying method, which has a better water saving effect. One way of variable spraying is to realize that the spraying field is non-circular (such as square, triangular, etc.). In t...
