Description

Technical Field

[0001] The utility model relates to the technical field of nozzle arrangement, in particular to an adjustable sealed rocker arm nozzle. Background Art

[0002] The rocker arm sprinkler is a commonly used sprinkler irrigation equipment for open-air places and an important sprinkler in irrigation equipment. It is mounted on the rocker arm shaft above the nozzle, with a rocker arm having a deflector plate and a guide plate at the front end. When the pressure water is ejected from the nozzle of the nozzle, it impacts the guide plate through the deflector plate, causing the rocker arm to generate a tangential motion force to rotate around the cantilever at an angle, and then return and hit the nozzle under the action of the torsion spring, causing the nozzle to rotate at an angle. This is repeated, and the sprinkler head can rotate in a full circle. If a limit device and a reversing mechanism are added to the sprinkler head, the nozzle can be reversed after rotating a certain angle, and fan-shaped sprinkler irrigation can be carried out. It has the advantages of wide application range, good spraying effect and high efficiency.
