Problems solved by technology

In recent years, some areas have begun to use new technologies such as sprinkler irrigation and infiltration irrigation. At present, rocker-arm sprinkler heads are used more for sprinkler irrigation. Uneven, easy to produce accumulated water under the sprinkler head bracket
In addition, in the existing sprinkler irrigation technology, the flow rates of multiple nozzles are different. The nozzles closer to the water source have high water pressure and flow rate, while the nozzles farther away from the water source have low water pressure and flow rate, resulting in uneven sprinkling of the entire land. result in inefficient water use

Abstract

The invention discloses a spray head used for water-conservancy irrigation. The spray head used for water-conservancy irrigation comprises a connecting pipe, a rotating assembly arranged on the connecting pipe, an automatic flow regulation assembly arranged in the rotating assembly, and a spray irrigation assembly connected with the rotating assembly. The turbo-type rotating spray head is simple in structure, capable of realizing automatic rotating and spraying, large in spraying area and uniformity and wide in application range; and the automatic flow regulation assembly can automatically regulate the flow rate according to the water pressure to make the flow rates of the spray head under a high water pressure and a low water pressure basically consistent, so that the water using efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of water conservancy irrigation, in particular to a sprinkler head for water conservancy irrigation. Background technique [0002] Due to the continuous decline of the groundwater level, flood irrigation can no longer be used for agricultural irrigation, and it is imperative and urgent to increase agricultural investment to implement water-saving irrigation. In recent years, some areas have begun to use new technologies such as sprinkler irrigation and infiltration irrigation. At present, rocker-arm sprinkler heads are used more for sprinkler irrigation. Uneven, easy to produce accumulated water under the sprinkler head bracket. In addition, in the existing sprinkler irrigation technology, the flow rates of multiple nozzles are different. The nozzles closer to the water source have high water pressure and flow rate, while the nozzles farther away from the water source have low water pressure and flow rate, ...
