Irrigation spray head for agricultural machinery

Abstract

The invention discloses an irrigation spray head for agricultural machinery. The irrigation spray head comprises a mounting cylinder, wherein a first connecting pipe is connected to the bottom end ofthe mounting cylinder; an inner pipe is arranged at the bottom end of the first connecting pipe, and the inner pipe is movably connected into a second connecting pipe in an inserted mode; threads areformed in the inner wall of the second connecting pipe, and a mounting sleeve is arranged at the bottom end of the second connecting pipe; the top of the mounting sleeve is hermetically connected to the bottom of the second connecting pipe in a sleeving mode, and the mounting sleeve is provided with a groove; the bottom of the mounting sleeve is hermetically connected to a water delivery pipe in asleeving mode, and the mounting cylinder is connected with a spray head; a metal hose is arranged at the top end of the mounting cylinder, and a mounting block is fixedly arranged at the top end of the metal hose. According to the irrigation spray head, the spray head with a hemispherical structure is provided with a plurality of spray holes, and the aperture of the spray holes is smaller as theaperture is higher and the spray distance is further as the aperture is smaller, so that the coverage of sprayed water mist is wider and the spray efficiency is higher.

Description

technical field [0001] The invention relates to the field of modern agricultural machinery industry, in particular to an irrigation nozzle for agricultural machinery. Background technique [0002] Agricultural irrigation methods can generally be divided into ground irrigation, ordinary irrigation and micro-pipes. In rural areas, water pipelines connected to wells are usually set up, and multiple farmlands are distributed on both sides of the water pipelines. Each farmland is fed with water hydrants through farmland irrigation. It is connected with the water pipeline. In the process of irrigating the farmland, it is necessary to use the sprinkler to spray water. However, the coverage of the water mist sprayed by the existing sprinkler is small, the spraying efficiency is low, and it cannot be adjusted according to the actual height of the crops. The height of the nozzle is adjusted, and the flexibility is poor, so it cannot meet the requirements. Contents of the invention ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide an irrigation sprinkler head for agricultural machinery, to solve the problem that the existing sprinkler nozzles have a relatively small coverage of water mist, low water spray efficiency, and the height of the sprinkler head cannot be adjusted according to the actual height of the crops. The problem of poor flexibility
