Embodiment Construction

[0019] Referring to Figure 1, the variable sprinkler combination sprinkler irrigation system consists of several main pipes, each main pipe is connected with several branch pipes, and each branch pipe is equipped with several variable nozzles. The flow rate of the variable nozzle is constantly changing in each spraying direction during the rotation process, that is, the flow rate of the nozzle is different under different rotation angles. Starting from the stability of system operation, it is required that the flow change should be as small as possible. When the variable nozzles are installed, the initial rotation angles of the variable nozzles on the branch pipes are staggered to make the flow changes offset each other, so that the flow rate changes on each branch pipe are minimized, and the flow stability of the variable nozzle combined sprinkler irrigation system is improved.

Abstract

The invention discloses a nozzle installation method for improving flux stability of spray irrigation system of variable-rate sprinkler. The combined spray irrigation system of variable-rate sprinkler is constituted by several dry tubes. Several branch tubes are set on each dry tube and several variable-rate sprinklers. Fluxes of variable-rate sprinkler on various spray directions are changed while the variable-rate sprinkler rotates, namely fluxes are different under different turning angle. For system running stability flux change can be reduced as far as possible. The invention provides a method that initial turning angles of variable-rate sprinklers are distributed in cross so that flux change can be counteracted with each other as far as possible and the range of flux change on each branch tube is the minimum so as to improve flux stability of spray combined irrigation system.

Description

technical field [0001] The invention belongs to the field of agricultural engineering, and relates to a method for installing a sprinkler device used in farmland, gardens and flower nurseries, and in particular to a method for installing a sprinkler to improve the flow stability of a variable sprinkler combination sprinkler irrigation system. Background technique [0002] The core technology of precision irrigation is to be able to develop equipment that needs to irrigate different amounts of water at different locations according to the shape of the crop or plot. In addition to equipment equipped with Global Positioning System (GPS) and Geographic Information System (GIS) on the irrigation machine, it mainly includes Variable water application irrigation sprinklers, controllers and variable flow pumps. Among them, the most critical equipment should be variable water application and precise irrigation sprinkler head. The variable sprinkler head can automatically adjust the f...
