Description

Technical Field

[0002] In agricultural production activities, crops need to be sprayed with pesticides to ensure their healthy growth. At present, various automated pesticide spraying devices have improved the efficiency of pesticide spraying and reduced the labor intensity of farmers. However, in some cases, small pesticide machines must be used to prevent and control crops. Although small pesticide machines are currently electric, they have reduced the labor intensity of farmers to a certain extent.

[0003] When optimizing existing pesticide spraying equipment, most of the optimization is reflected in the effect of the device on pesticide spraying. For example, the Chinese utility model patent with application number CN201911370129.0 discloses a "pesticide sprayer". This utility model patent has a double-sided spraying device, which improves the spraying efficiency and reduces the labor intensity. It avoids the poor prevention and control effect and seedling burning caused by uneven pesticide spraying, reduces the damage to crops and the amount of pesticides contaminated by users, is simple and safe to operate, and has good practicality.

[0004] Although the above method has certain advantages in improving the spraying effect, it still has certain disadvantages: the use of electric drive for spraying requires the equipment to be equipped with batteries and controllers, which increases the weight of the equipment, and the nozzle will only spray in one place, which will cause uneven spraying of pesticides and reduce crop yields.
