Problems solved by technology

If the droplet size of the spraying liquid is too small, and the ambient temperature is too high and the relative humidity is low, the droplets have evaporated in the air or deposited on the surface of the leaves as small droplets before falling on the leaves of the fruit trees, which will affect the quality of the fruit trees. The capillary pores on the surface of the leaves absorb the liquid medicine, so that the ideal pest control effect cannot be produced
[0004] In addition, when the sprayer is relatively far away from the fruit trees, if the droplet size is too small, the droplets will be evaporated before settling on the leaves of the fruit trees, thus losing the effect of pest control

Embodiment

[0028] refer to Figure 1 to Figure 3 , the present embodiment relates to a sprayer, including a liquid medicine spraying system 1, an ultrasonic atomization system 2 and an air supply system 3, and the liquid injection port of the liquid medicine spray system 1 is arranged at the air outlet of the air supply system 3 , the ultrasonic output port of the ultrasonic atomization system 2 is facing the liquid spray port of the chemical liquid spraying system 1 to re-atomize the atomized chemical liquid sprayed from the liquid spray port.

[0029] The liquid medicine spraying system 1 of this structure atomizes and sprays the medicine liquid, and at the same time uses an ultrasonic system to perform secondary oscillation and atomization on the medicine liquid atomized and sprayed from the medicine liquid spraying system 1, so that the atomized liquid The droplet size is smaller than the atomization particle size of the nozzle. When the liquid spraying system 1 adjusts the spraying...

Abstract

The invention discloses an air-driven ultrasonic secondary atomization variable particle size sprayer, which comprises a medicinal liquid spraying system, an ultrasonic atomization system and an air conveying system. At the air outlet of the system, the ultrasonic output port of the ultrasonic atomization system is facing the liquid injection port of the liquid spraying system to re-atomize the atomized liquid sprayed from the liquid spray port. The medicinal liquid spraying system of the present invention atomizes and sprays the medicinal liquid, and at the same time performs secondary oscillation and atomization on the medicinal liquid atomized and sprayed from the medicinal liquid spraying system by using an ultrasonic system, so that the atomized liquid droplets The particle size is smaller than the atomized particle size of the nozzle, which can significantly improve the uniformity of droplet distribution, effectively inhibit the pesticide residue from exceeding the standard, and realize the purpose of maximizing the control of diseases and insect pests with the smallest spraying amount of liquid medicine and the smallest environmental pollution. It can be applied to According to the requirements of different spraying operation environments and spraying operation objects, it has the beneficial effects of adjustable droplet size, saving liquid medicine and wide application range.

Description

technical field [0001] The invention relates to a sprayer, in particular to an air-driven ultrasonic secondary atomization variable particle diameter sprayer. Background technique [0002] Due to the different microstructures of different plant leaves, the degree of hydrophilicity of the leaf surface varies. For the surface of leaves with poor hydrophilicity, if the particle size of the sprayed liquid droplets is too large, the droplets will gather on the surface of the leaves to form larger droplets. When the droplets aggregate to a certain extent, the droplets will Detached from the leaves and lost to the soil, resulting in a waste of pesticides, and the wasted pesticides will grow at the rate of the cube of the droplet diameter. In addition, it will cause soil pollution. [0003] For systemic pesticides, in the liquid state, the particulate matter in the pesticide is more likely to be absorbed by the capillary pores on the surface of fruit tree leaves. The more the lea...
