Energy-saving irrigation spray head

Abstract

The invention belongs to the technical field of energy-saving irrigation, and specifically relates to an energy-saving irrigation spray head. The spray head comprises a mounting ring, a connecting pipe, a mounting pipe, a cap, a protective cover and a spraying mechanism; the mounting ring is fixedly mounted on a water pipe and communicates with the water pipe; the connecting pipe is fixedly mounted at the upper end of the mounting ring; the connecting pipe is made of a ceramic silicone rubber material, and is set as a folding pipe; the upper end of the connecting pipe is fixedly connected with the mounting pipe; the cap is arranged above the mounting pipe; and the outer surface of the mounting pipe is initially sleeved with the protective cover. When a spraying area of an adjusting head needs to be enlarged, the water pressure in an elastic pipe can be increased only by increasing the transmission speed of water flow, so that the elastic pipe expands to push the adjusting head to move upwards, and the spraying range of the adjusting head is enlarged; the larger the water pressure is, the wider the spraying range is, that is, the spraying irrigation range is adjusted through the water pressure, and a complex adjusting mechanism is not needed, so that not only is the cost greatly reduced, but also the spraying range can be automatically adjusted, and water source waste is avoided.

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
