AI Technical Summary

Technical Problem

During flight, existing agricultural drones experience instability due to fluctuations in the pesticide solution inside the tank, affecting flight stability and potentially causing the drone to crash or collide with obstacles.

Method used

It adopts a medicine tank structure with a medicine storage section, a drive section and a pump body. The pump body pumps the medicine into the telescopic tube. The telescopic tube and the pressure plate work together to keep the medicine full and avoid fluctuations. Combined with elastic components and flow control, it ensures a stable supply of medicine.

Benefits of technology

It achieves a stable supply of liquid medicine during drone flight, improves flight stability, avoids the impact of liquid medicine fluctuations on the center of gravity, and has a simple structure without increasing the weight of the drone.

Abstract

This invention relates to the field of unmanned aerial vehicle (UAV) technology and discloses a pesticide spraying UAV, including a frame with a rotor assembly, a pesticide tank and a spraying assembly connected to the pesticide tank mounted on the frame, the pesticide tank including a storage section, a drive section, and a pump body, a pressure plate slidably connected inside the storage section, the drive section including a connecting plate mounted on the frame, a telescopic tube detachably connected to the connecting plate, the lower end of the telescopic tube detachably connected to the pressure plate, an elastic component between the pressure plate and the connecting plate, the pump body being connected to the bottom of the storage section via a water inlet pipe, and the pump body being connected to the telescopic tube via a water outlet pipe, the water outlet pipe having a water outlet valve, and a spraying pipe being located at the upper end of the telescopic tube, the spraying pipe being connected to the spraying assembly, the spraying pipe having a spraying valve. This invention has the following advantages and effects: the pesticide solution is always full in the storage section, and the pesticide solution in the telescopic tube is also always full, therefore, the pesticide solution will not fluctuate within the storage section and the telescopic tube, ensuring the stability of the UAV operation.
