Background
At present, China vigorously pushes a water-fertilizer-pesticide integrated technology, and plays a key role in stably improving the agricultural yield. In the fruit tree planting in the hilly areas of China, a system for quantitatively applying pesticide and irrigating grape crops is not perfect enough, and particularly in the process of realizing water-fertilizer-pesticide integrated irrigation and pesticide application, the atomizing nozzle is not strong in pertinence and cannot be completely suitable for the actual growth condition of the leaves of the grape crops.
The spray head is a key component of the pesticide application technology and directly influences the pesticide application effect. At present, the atomization mode of the pesticide application spray head adopts hydraulic atomization and pneumatic atomization. The hydraulic atomization is characterized in that: the fog drops are sensitive to pressure change, the atomized particle size is large, the change of the particle size of the fog drops is obvious along with the change of the viscosity of the liquid, the range is short, and the like, so that waste and environmental pollution are easily caused. The conventional pneumatic atomization has the characteristics of good droplet penetrability, high gas-liquid ratio, high gas consumption rate and high energy consumption. Aiming at the problems, the invention adopts gas-liquid two-phase flow atomization, can generate fine and uniform fog drops and can improve the uniformity of pesticide application. Simple structure, low energy consumption, be adapted to hilly area grape crop blade spraying, have very important meaning in the aspect of the energy saving reduces environmental pollution.
