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-assisted ultrasonic secondary atomization variable-particle-size atomizing sprayer which comprises a pesticide liquid spraying system, an ultrasonic atomizing system and a blast system. A liquid spraying port of the pesticide liquid spraying system is arranged at an air outlet of the blast system, and an ultrasonic output port of the ultrasonic atomizing system faces the liquid spraying port of the pesticide liquid spraying system to re-atomize atomized liquid sprayed from the liquid spraying port. By the pesticide liquid spraying system for atomizing spraying of pesticide liquid and the ultrasonic atomizing system for secondary oscillation atomization of the pesticide liquid atomized and sprayed from the pesticide liquid spraying system, the particle size of atomized liquid drops is smaller than the atomization particle size of a nozzle, and accordingly droplet distribution uniformity can be improved remarkably, excessive pesticide residues are effectively inhibited, and maximization in control of pest and disease damages is realized under conditions of minimal pesticide liquid spraying quantity and minimal environment pollution. Moreover, the atomizing sprayer is capable of meeting requirements of different spraying operation environments and spraying operation objects and has advantages of droplet particle size adjustability, saving of pesticide liquid 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...
