An energy-saving irrigation nozzle

Abstract

The invention belongs to the technical field of energy-saving irrigation, and specifically relates to an energy-saving irrigation nozzle, which includes a mounting ring, a connecting pipe, a mounting pipe, a cap, a protective cover and a spraying mechanism; the mounting ring is fixedly installed on a water pipe and communicated with the water pipe, The upper end of the installation ring is fixedly installed with a connecting pipe; the connecting pipe is made of ceramic silicon rubber material, the connecting pipe is set as a folded pipe, and the upper end of the connecting pipe is fixedly connected with a mounting pipe; The outer surface of the tube is initially sleeved with a protective cover; when it is necessary to expand the spraying area of ​​the adjusting head, the water pressure in the elastic tube can be increased only by increasing the transmission speed of the water flow, so that the elastic tube expands and pushes the adjusting head to move upward. Further expand the spraying range of the adjusting head, and the higher the water pressure, the wider the spraying range, that is, the water pressure can be used to adjust the spraying irrigation range without complicated adjustment mechanisms, which not only greatly reduces the cost, but also automatically adjusts the spraying range to avoid Cause water waste.

Description

technical field [0001] The invention belongs to the technical field of energy-saving irrigation, in particular to an energy-saving irrigation nozzle. Background technique [0002] Technical measures for replenishing the water needed by crops. In order to ensure the normal growth of crops and obtain high and stable yields, crops must be supplied with sufficient water. Under natural conditions, often due to insufficient precipitation or uneven distribution, the water requirements of crops cannot be met. Therefore, artificial irrigation must be carried out to make up for the deficiency of natural rainfall. Irrigation, i.e. irrigating the land with water. The principle of irrigation is that the amount of irrigation, the frequency of irrigation and the time should be determined according to the water demand characteristics of medicinal plants, growth stages, climate, and soil conditions, and should be timely, appropriate, and rational irrigation. The types mainly include pre-...

AI Technical Summary

Problems solved by technology

[0003] When irrigating farmland, due to the large amount of irrigation and labor-intensive labor, mechanical irrigation is now used in farmland, that is, multiple sprinklers are installed in the farmland to realize automatic irrigation. However, this method makes the sprinklers The installation position is fixed and cannot be moved. When the crop cultivation range of the next season is changed, it is difficult for the sprinklers to achieve full coverage irrigation. The solution at this time can only be to install more sprinklers or to use artificial irrigation in places where irrigation is missed. If erection Multiple nozzles will undoubtedly further increase the production cost. At the same time, the spraying range of the nozzles is fixed and difficult to adjust, which will cause a lot of waste of water resources. If artificial irrigation is adopted, it will undoubtedly consume a lot of manpower and material resources
