Description

Technical Field

[0001] The present invention relates to the technical field of drone pesticide spraying, and more particularly to a drone pesticide spraying device for agriculture. Background Art

[0002] Agricultural drones are able to adapt to various complex terrains and perform precise operations in agricultural production. When spraying pesticides on large areas of farmland, drones can achieve precise operations by flying at low altitudes, thereby reducing costs and improving efficiency. In summary, the inventors have found that the existing drone pesticide spraying device mainly has the following defects: since the current drone pesticide spraying device performs flight operations by adding a medicine box and a spray pipe at the low end, the medicine box is continuously in a suspended state, and at the same time, a large amount of liquid medicine is carried inside. As a result, the liquid medicine generated by inertia will shake in the medicine box during flight. Therefore, the shaking of the liquid medicine inside the medicine box will affect the stable flight of the drone, and the stability of the normal operation of the drone will be reduced under the influence of the continuous shaking factor.
