Description

Technical Field

[0001] The utility model relates to the technical field of irrigation equipment, in particular to an underground lifting sprinkler head. Background Art

[0002] Buried sprinklers are directly buried underground, remaining hidden beneath the surface during non-irrigation periods. They are primarily used for green space irrigation and some cash crops, boasting a long service life and minimal impact on field operations. The sprinklers are completely buried underground. During irrigation, water pressure pushes them out of the ground or above the crop surface to apply the spray. Once irrigation is complete, gravity retracts them below the surface due to the lack of water pressure, effectively concealing the irrigation equipment.

[0003] Existing buried sprinklers can be lifted up to spray water during irrigation, but sometimes the lifted pipes tilt under the influence of water flow, and irrigation work cannot be carried out stably after the sprinklers tilt. In addition, many sprinklers require additional driving and lifting structures to push the sprinklers up and down, which results in high overall costs. Utility Model Content
