Anti-blocking back-washing adjustable micro spray nozzle

Abstract

The invention discloses an anti-blocking back-washing adjustable micro spray nozzle. The anti-blocking back-washing adjustable micro spray nozzle comprises a micro spray nozzle top cover, a water distribution piece, a micro spray nozzle base and an overhead kick joint; a cylindrical containing cavity is formed in the micro spray nozzle top cover, a water inlet hole is formed in the bottom of the containing cavity, the water distribution piece is placed into the containing cavity, a pair of water passing grooves penetrating the water distribution piece are formed in the water distribution piece, and an inward concave type water leading groove communicated with the water passing grooves is formed in the end face of the water distribution piece; an adjusting groove hole penetrating the base is formed in the micro spray nozzle base, a water spraying hole way is arranged in the overhead kick joint, a semispherical adjusting joint block is arranged at the end of the overhead kick joint, and the adjusting joint block is placed in the adjusting groove hole. Inclined-angle water spraying of the overhead kick joint in the micro spray nozzle base is achieved, the watering area of the spray nozzle is increased, the watering efficiency is improved, due to the reasonable watering design, the growth rate of plants is greatly improved, and internal blockage of the joint can be prevented. Due to the adoption of the structure of the water distribution piece, the continuous micro water draining can be achieved, and a large number of water resources are saved.

Description

technical field [0001] The invention relates to a large-scale planting irrigation equipment, in particular to an adjustable micro sprinkler head for anti-clogging and backwashing. Background technique [0002] At present, in the production of modern planting industry, the most important link is the irrigation of plants. In irrigation, it is necessary to use microporous water nozzles. The water in the water nozzles is not limited to simple irrigation water. Moreover, a large amount of nutrient solution is mixed into the irrigation water, and the added nutrient solution has a pair of solubility, so as to ensure the good growth of plant products. [0003] But the traditional water nozzle has the following defects: first, the water spray angle of the water nozzle cannot be adjusted during use, and after the water nozzle is fixed, it can only spray water in one direction, so that the water spray angle of the water nozzle is fixed. Thereby a narrower watering area is defined, so ...

Problems solved by technology

[0003] But the traditional water nozzle has the following defects: first, the water spray angle of the water nozzle cannot be adjusted during use, and after the water nozzle is fixed, it can only spray water in one direction, so that the water spray angle of the water nozzle is fixed. Thereby limiting a narrower watering area, so that there is a watering blind area when watering, which affects the growth of plants

Second, when the traditional water nozzle is watering, because the water is mixed with nutrient solution, and the nozzle hole of the water nozzle is small, the problem of nozzle blockage often occurs, which affects the efficiency of watering and reduces the water consumption. plant growth rate
