[0003] The pesticide spraying device is usually composed of a pesticide tank, a pump body, a nozzle, a control system and other key components. Its working principle is to generate pressure through the pump body to pressurize the pesticide liquid in the pesticide tank and deliver it to the nozzle to form a mist sprayed on the surface of the crops. The operation process is simple and convenient. The user only needs to set the spraying parameters according to the crop type and pest situation, and start the device to complete the spraying operation. The device exhibits advantages such as high efficiency, energy saving and environmental protection in practical application. Its precise spraying technology can reduce pesticide waste, reduce environmental pollution, and ensure crop safety.
