Abstract

The invention provides a double-channel micro-spray head with different structures, the nozzle and the fixed nozzle are connected to the water supply hose through the joint, the water supply hose is connected to the water delivery main pipe, and the pressurized water flow enters the fixed nozzle from the water delivery main pipe through the water supply hose , at the same time, the pressurized water flow enters the nozzle from the water supply main pipe through the water supply hose; the water flow passes through the refraction of the first arc-shaped diversion groove and the second arc-shaped diversion groove, generating a backward thrust, pushing the rotating body to rotate around the axis at high speed, The refracted water flow is ejected and crushed at a certain angle along the tangential direction of the rotation of the rotating body, and sprayed within the effective range; compared with the second arc-shaped diversion groove, the straight line from the beginning to the end of the first arc-shaped diversion groove The distance is relatively large, and the spraying angle at the end of the first arc-shaped diversion groove is relatively large, so the effective range of the water sprayed along the end is small, and the first water outlet hole of the fixed nozzle is small in size, so the water output is small; The combination of aspects helps to maintain the uniformity of spraying in different ranges from near to far.

Description

technical field [0001] The invention belongs to the technical field of micro-sprinkler irrigation for agricultural irrigation equipment, and in particular relates to a dual-channel micro-sprinkler head with different structures. Background technique [0002] The lifeblood of man lies in the fields, and the lifeblood of fields lies in water. Although the proportion of agricultural water consumption in the total water consumption of the whole society has dropped from 63% in 2000 to 55% at present, agriculture is still the largest water user. The effective utilization coefficient of farmland irrigation water nationwide is 0.532, which means that Only 0.532 cubic meters of 1 cubic meter of water is absorbed and utilized by crops, which is far from the utilization coefficient of 0.7 to 0.8 in developed countries. With the adjustment of my country's agricultural planting structure and the improvement of farmers' economic conditions, the planting area of ​​cash crops and greenhous...
