Stirring device and method for pesticide spraying of plant protection unmanned aerial vehicle

The invention discloses a stirring device and method for pesticide spraying of a plant protection unmanned aerial vehicle, and belongs to the technical field of spraying of plant protection machines. According to the pesticide mixing and stirring device, the first twisted blades and the second twisted blades are arranged in a mirror image mode and are opposite in direction, in the rotating process, the first twisted blades guide water flow of pesticide in an upward vortex mode, the second twisted blades guide water flow of the pesticide in a downward vortex mode, then a convection state is formed, and finally the pesticide mixing and stirring efficiency is effectively improved; the multiple charging barrels surround the outer side of the storage battery, pesticide in the charging barrels has low temperature, the low temperature of the pesticide acts on the storage battery, then heat dissipation of the storage battery is achieved, meanwhile, the pesticide is stirred through the stirring assembly, and in the st
