Description

technical field

[0001] The invention relates to an irrigation sprinkler head, in particular to a hanging irrigation sprinkler head. Background technique

[0002] The commonly used hanging irrigation method is to set a water supply pipe on the top of the crops, and then set a number of water spray holes at different positions on the outer surface of the water supply pipe, and then install nozzles on each water spray hole, and feed the water supply pipe with high pressure when in use. Water is sprayed in different directions by each nozzle.

[0003] For example, on May 26, 2010, an invention patent with the patent number ZL200920182410.7 and the name "suspended liquid spray pipe with nozzle" was disclosed, which includes a suspended liquid spray pipe, and the pipe wall of the liquid spray pipe is provided with a There are liquid spray holes, and nozzles are arranged on part of the liquid spray holes or all the liquid spray holes. Due to the density and spacing of the distrib...
