Vertical rocker arm type automatic nozzle

Abstract

The invention discloses a vertical rocker arm type automatic nozzle which comprises a nozzle seat, a bend and a flow stabilizing pipe seat. One end of the flow stabilizing pipe seat is connected to aflow stabilizing pipe, an upper reversing seat is mounted at one end of the flow stabilizing pipe in a sleeving manner, and one end of the upper reversing seat is connected to a driving arm and the other end of the upper reversing seat is connected to a driven arm. The invention relates to the field of nozzles. As a water flow impacts a flow guide plate, matched with a rocker arm, the nozzle rotates intermittently to irrigate and meanwhile, a spiral impeller under impact of the water flow rotates anticlockwise to disperse the water flow initially, and the rotating spiral impeller is to be in contact with the lower wall of a cross plate and the cross plate drives an adjusting plate to ascend upward so as to reduce the inner diameter of the nozzle, so that the speed of a fluid is increased effectively and therefore, the spray irrigation range is improved. A scattering plate driven by a motor is to rotate to scatter the water flow to spray the water flow in a waterfall manner, so that thespray irrigation area is increased greatly and therefore, convenience is brought to use.

Description

technical field [0001] The invention relates to the technical field of sprinklers, in particular to a vertical rocker-arm type automatic sprinkler. Background technique [0002] With the development of agricultural level, large-scale planting has become the mainstream trend of agricultural development, and irrigation is particularly important as a link that can directly affect the quality and yield of crops. On the capstan, the water turbine is driven to rotate by the sprinkler pressure water, and the capstan is driven to rotate through the speed change device, and the irrigation machine that pulls the sprinkler truck to move and spray automatically. [0003] Chinese patent CN2387973 discloses an improved vertical rocker nozzle, which consists of a nozzle seat, an elbow, a nozzle body, a rotating part, a reversing part and the like. Its main technical features are: the steady flow tube is stretched and formed by aluminum alloy. [0004] This type of nozzle can use the wate...

AI Technical Summary

Problems solved by technology

[0004] This type of nozzle can use the water body to impact the deflector so that the nozzle rotates intermittently, thereby realizing large-scale irrigation. However, the water flow of this type of nozzle is columnar, which consumes a lot of water, and the columnar water spraying area is small, resulting in a larger area of ​​spraying irrigation. low, inconvenient to use
