Embodiment Construction

[0013] The elevation angle automatic adjustment variable sprinkler nozzle is composed of four parts: the nozzle assembly, the rotating connector, the elevation angle adjustment mechanism, and the flow channel mechanism. The key parts of the present invention are the spray head assembly, the rotary connection piece and the elevation angle adjustment mechanism. The present invention realizes variable spraying by changing the elevation angle of the spray head and further changing the range of the spray head.

[0014] The working process is as follows: the elevation angle is automatically adjusted and the variable sprinkler head is powered by the reaction force of the water flow. The rotating shaft 16 and the shaft sleeve 15 form a rotating pair, so that the spray body 2 and the nozzle 1 can rotate on a vertical plane with the adapter 17 and the rotating shaft 16 as axes. The guide rail 26 is welded on the chassis 26, and is fixed on the swivel connection seat 5 by the bolt 3, an...

Abstract

The invention discloses an elevation angle automatic regulation variable spray nozzle, which belongs to nozzle equipment for spraying, spray irrigation, landscape fountains and the like. The nozzle comprises a nozzle component, a rotary connecting piece, an elevation angle regulation mechanism and a flow channel, wherein the key parts are the nozzle component and the elevation angle regulation mechanism. The nozzle is driven to rotate by the recoil force of water flow. In a rotation process of the nozzle, an adjusting rod 19 drives a guide rod 17 to do synchronous circular movement with the rotation of the nozzle along a guide rail 26; a roller 24 slides along the guide rail 26 all the time; and because the height of each place of the periphery of the guide rail 26 is different, the guiderod 18 moves along the vertical direction while doing circular movement to drive a spraying body 2 and a nozzle 1 to rotate around a spraying body 17, and then an elevation angle of the nozzle and the spraying range of the nozzle are changed. Compared with the traditional variable spray nozzle, the elevation angle automatic regulation variable spray nozzle has the advantages of stable and reliable running, uniform spraying and simple adjustment.

Description

technical field [0001] The invention belongs to sprinkler equipment used for sprinkling, sprinkling irrigation, landscape fountains, etc., and particularly refers to a spraying nozzle with automatic adjustment of variable elevation angle. Background technique [0002] The sprinkler is the key equipment that affects the irrigation quality of the sprinkler irrigation system, and its performance directly affects the quality of sprinkler irrigation. Traditional circular sprinkler nozzles are not conducive to combined sprinkler irrigation and irrigation of special terrain. In combined sprinkler irrigation, in order to obtain higher spraying uniformity, it is necessary to reduce the combined spacing of sprinklers and increase the overlapping rate of sprinkled area, but this requires increasing the density of sprinkler heads and pipeline layout, which will lead to increased sprinkler irrigation intensity, waste of water resources and engineering investment increase. In some speci...
