Controllable variable spray gun

Abstract

The invention discloses a controllable variable spray gun comprising a gun body, a booster pump and a gun connecting pipe. A water inlet of the booster pump is communicated with a sprayer pipe of a central-pivot sprinkler. A water outlet of the booster pump is connected with a water inlet of the gun body through the gun connecting pipe. The front of the gun body is provided with a nozzle. The tail of the gun body is mounted at the tail end of a straddle member of the central-pivot sprinkler, through a gun horizontal-rotation mechanism. The controllable variable spray gun has the advantages that spraying angle of the gun body can be automatically adjusted through a preset program, four corners of a square plot missed by the sprinkler can be evenly irrigated, utilization rate of land is increased, and the landform around the square plot is never affected.

Description

technical field [0001] The invention relates to a spray gun for irrigation, in particular to a controllable variable spray gun for a central pivot type sprinkler irrigation machine. Background technique [0002] At present, the central pivot sprinkler has been widely used in many countries and regions. Compared with other sprinklers, this equipment has a high degree of automation, a large control area, strong adaptability to crops and terrain, good spraying uniformity, and water saving. , energy saving and other advantages, but also has obvious defects, that is, the four corners of the square plot cannot be irrigated, resulting in low land utilization. There are various drawbacks in the existing solutions to the corner leakage irrigation problem, and the problem of corner leakage irrigation of the central pivot type sprinkler irrigation machine cannot be well solved. Contents of the invention [0003] The technical problem to be solved by the present invention is to provi...
