Automatic opening and closing type nozzle for fruit and vegetable sprinkling irrigation

Abstract

The invention discloses an automatic opening and closing type nozzle for fruit and vegetable sprinkling irrigation. The automatic opening and closing type nozzle for fruit and vegetable sprinkling irrigation comprises a nozzle body, installing pieces and a refraction cone. An inner thread is arranged on the nozzle body. The nozzle body is further provided with a water inlet hole and a nozzle hole. A first groove is formed in the water inlet hole of the nozzle body. The two sides of the installing pieces stretch into the first groove. The installing pieces are further provided with water passing holes. The refraction cone sequentially comprises a taper disc, a connecting section, an installing section and a positioning section. The installing section of the refraction cone penetrates the installing pieces. A tension spring is arranged on the installing section of the refraction cone, one end of the tension spring abuts against the connecting section of the refraction cone, and the other end of the tension spring abuts against the installing pieces. The scheme has the beneficial effects that under the acting force of the tension spring, when the nozzle does not work, the refraction cone automatically abuts against the nozzle hole, and when sprinkling irrigation is carried out, the refraction cone overcomes the acting force of the tension spring through the action of pressure water flow and is automatically separated from the nozzle hole, and therefore the nozzle in the scheme can be automatically opened and closed.

Description

technical field [0001] The invention relates to a sprinkler head, in particular to an automatic opening and closing type sprinkler head for fruit and vegetable sprinkling irrigation. Background technique [0002] Sprinkler irrigation is an irrigation method that uses special equipment such as sprinklers to spray pressurized water into the air to form water droplets and land on the surface of crops. Under natural conditions, insufficient precipitation or uneven distribution of precipitation often cannot meet the water needs of fruits and vegetables during the growth process, so sprinkler irrigation systems are widely used in fruit and vegetable planting. [0003] A complete sprinkler irrigation system generally consists of a sprinkler head, pipe network, head and water source. The sprinkler head is used to disperse water into droplets and spray it evenly on the planting area like rainfall. When the nozzle head in the traditional sprinkler irrigation system is not working, the...

Problems solved by technology

[0003] A complete sprinkler irrigation system generally consists of a sprinkler head, pipe network, head and water source. The sprinkler head is used to disperse water into droplets and spray it evenly on the planting area like rainfall. When the nozzle head in the traditional sprinkler irrigation system is not working, the nozzle hole There is no protective device at the place, so foreign substances can easily enter the spray hole, which can easily cause blockage of the spray hole and affect the normal operation of the sprinkler irrigation system.
