High-uniformity anti-blocking insect-preventing rotating nozzle

Abstract

The invention provides a high-uniformity anti-blocking insect-preventing rotating nozzle. The high-uniformity anti-blocking insect-preventing rotating nozzle comprises an insect-preventing shell, and components arranged in the insect-preventing shell, namely a nozzle working assembly and a filter device with a U-shaped section. The insect-preventing shell comprises a lower insect-preventing shell and an upper insect-preventing shell, the two of which are in threaded connection with each other; the nozzle working assembly comprises a pin, a nozzle top cover, a water inlet nozzle, a fixed assembly arranged in the upper insect-preventing shell and a water injection assembly arranged above the water inlet nozzle. The high-uniformity anti-blocking insect-preventing rotating nozzle has the following advantages: the rotating nozzle is provided with the filter and capable of preventing blocking, and water even poor in quality can be applied to irrigation; impurities such as mosquitoes, dust and grains of sand can be prevented from intrusion to block the nozzle, so that the maintenance cost can be greatly reduced and the service life of the nozzle can be increased; the effects of uniform irrigation, excellent wind resistance, corrosion resistance and better steadiness and reliability can be achieved; a double-flow channel water outlet is capable of guaranteeing smooth and perfect operation of the nozzle, and a water division step is arranged at one of two curved-surface flow channel water outlets so that the ranges of the two water outlets are different, and therefore, water distribution is evener.

Description

technical field [0001] The invention relates to the technical field of irrigation nozzles, in particular to a high-uniform anti-clogging and anti-insect rotary nozzle. Background technique [0002] At present, the working place of the sprinkler is basically located in farmland, green area, greenhouse and other places. When the sprinkler is not working, outdoor insects can easily crawl into the sprinkler, including ants, snails, ground centipedes, spiders and weevils; in addition, dust, External factors such as sand and weeds often block the nozzles, affecting the normal operation of the nozzles. When a large area of ​​the nozzles is invaded by insects, the normal nozzles cannot work normally, which seriously affects the irrigation needs of crops, and manual cleaning of the nozzles is very troublesome and requires a lot of The manual operation has greatly affected the normal irrigation operation. [0003] In the Chinese patent application number 201320683548.1: a sprinkler h...

AI Technical Summary

Problems solved by technology

However, high water pressure is required to have a certain range when the rocker sprinkler sprays, and high water pressure will cause the rocker sprinkler to continuously hit the rocker rotation when it is working, which makes the pole shake all the time, and water droplets continue to fall from the vertical. Splashes under pole, difficult to secure

Moreover, the higher starting pressure makes the pump lift more demanding, but the cost of the pump is high

In addition, the use of rocker nozzles cannot be installed on mobile sprinkler irrigation equipment; and because there is no reasonable water distribution device, the water distribution is uneven, resulting in uneven irrigation, and there are blind spots for irrigation, which eventually makes plants grow poorly due to uneven irrigation, so the same The irrigation area requires more rocker sprinklers, which increases the cost of irrigation
