An agricultural ultrasonic atomization spraying device

Abstract

The invention relates to an agricultural ultrasonic atomization spraying device. The agricultural ultrasonic atomization spraying device comprises a sprayer barrel body for containing pesticide liquid and a closed device, wherein one or more ultrasonic atomizers capable of atomizing pesticide liquid are arranged in the closed device, a pesticide inlet, an air inlet and a mist outlet are formed in the closed device, the pesticide medicine inlet is connected with the barrel body, an air blower for blowing air in is connected to the air inlet through an air inlet pipe, the mist outlet is connected with a spraying pipe, and a sprayer nozzle for spraying vaporific pesticide liquid is arranged on an end opening of the spraying pipe. The surface of the liquid is swollen through ultrasonic directional pressure intensity, cavatition happens around the swollen liquid surface, the liquid is atomized into small molecule aerial fog, and therefore water molecules can directly act on the surfaces of crops through the aerial fog, spraying or fertilizer application or insect killing can be performed on the crops more effectively, water, pesticide, fertilizer and the like are saved, and the food safety problem caused by uneven pesticide spraying is prevented.

Description

[0001] 【Technical field】 [0002] The invention relates to a spraying device, in particular to an agricultural ultrasonic atomization spraying device. [0003] 【Background technique】 [0004] With the improvement of the level of science and technology, agricultural sprinklers have been widely used in agricultural planting, forestry maintenance and other fields to spray, fertilize or kill vegetables, fruits, crops and forest trees. It is generally called a human-driven sprinkler, and it is divided into hand-held, backpack, and shoulder-mounted according to the carrying method. [0005] Traditional agricultural sprinklers use Bernoulli's principle. Water flows from high pressure to low pressure. When passing through the trident pipe, the low-speed flowing water rushes to the high-speed flowing air, and the water is torn into small droplets by the high-speed air. These small water droplets pass through The nozzle sprays out. However, the commonly used agricultural sprinklers con...
