Elastic inner cavity type anti-vibration pesticide box for plant protection unmanned aerial vehicle

Abstract

The invention relates to an elastic inner cavity type anti-vibration pesticide box for a plant protection unmanned aerial vehicle. The elastic inner cavity type anti-vibration pesticide box is characterized in that a check valve is fixed into a water injection opening, a ball valve is arranged at a water outlet, and a liquid storage bag is arranged between the check valve and the ball valve in a connected manner. The elastic inner cavity type anti-vibration pesticide box has the advantages that the liquid storage bag is elastic and anticorrosion, gaps between the liquid storage bag and a pesticide box are filled with elastic materials, the elastic materials can be compressed when the liquid storage bag is filled with pesticide liquid and is expanded, and can be expanded when the pesticide liquid in the liquid storage bag is reduced and the liquid storage bag is contracted, the gaps between the pesticide box and the liquid storage bag are always filled with the elastic materials, the inner wall of the liquid storage bag always clings to the pesticide liquid, and accordingly the liquid storage bag assuredly always keeps being fixedly positioned in the pesticide box when the plant protection unmanned aerial vehicle shakes; the integral gravity center of anti-vibration pesticide box only can longitudinally change without transverse changing along with reduction of the pesticide liquid in pesticide application procedures of the plant protection unmanned aerial vehicle, accordingly, the integral stability of the pesticide box can be greatly enhanced, and the problem of deterioration of the flight stability of an existing plant protection unmanned aerial vehicle in pesticide application procedures due to vibration of pesticide liquid in an existing pesticide box can be fundamentally solved.

Description

technical field [0001] The invention belongs to the technical field of agricultural aviation plant protection machinery and equipment, and in particular relates to an anti-vibration medicine box of an elastic inner cavity type plant protection drone. Background technique [0002] Ensuring national food security is a long-term basic national policy of China. Crop pests and diseases have long been one of the main factors affecting grain yield and grain quality, and chemical control is currently the most convenient and effective way to control pests and diseases. The plant protection machinery currently used in China is mainly manual and small mechanical (electric) sprayers. Plant protection operations are labor-intensive, costly, and poorly adaptable to the environment. It is difficult to guarantee the effect of pest control. At the same time, the waste of pesticides and water resources is serious. The problem is becoming more and more prominent. Agricultural aviation plant ...

AI Technical Summary

Problems solved by technology

During the operation of the plant protection drone, due to the unavoidable influence of human or external factors, the flight attitude, flight speed and flight altitude will change. At this time, if the liquid medicine in the medicine box loaded by the drone is not reasonably restricted Vibration will occur, the offset of the center of gravity of the medicine liquid in the medicine box and the impact on the wall of the medicine box will reduce the flight stability of the plant protection drone, making it more difficult to control the flight, and serious cases will lead to a crash

This undoubtedly has an adverse effect on the safety and quality of spraying operations.

During the spraying process of the plant protection drone, the amount of liquid medicine gradually decreases, which leads to the change of the load of the drone. The change of the center of gravity of the medicine box will affect the overall stability of the plant protection drone, and the lateral change of the center of gravity of the medicine box is particularly serious.

Most of the existing medicine boxes for plant protection drones use heterosexual structures or internal partitions to reduce the vibration of the liquid medicine, which does not solve the problem from the root cause, and the actual application effect is not ideal
