Description

Technical Field

[0001] The utility model relates to the technical field of liquid medicine tank mixers, in particular to a liquid medicine tank mixer for a plant protection drone. Background Art

[0002] Plant protection drones, also known as unmanned aerial vehicles, are unmanned aircraft used for agricultural and forestry plant protection operations. This type of drone consists of three parts: a flight platform (fixed-wing, helicopter, multi-axis aircraft), a navigation flight control, and a spraying mechanism. Spraying operations are achieved through ground remote control or navigation flight control. It can spray pesticides, seeds, powders, etc. With the rapid development of drone technology, more widely used "agricultural drones" are gradually replacing "plant protection drones". Agricultural drones are not only used for spraying and applying pesticides, but also for spreading fertilizers, seeds, feed, and other tasks to meet the diverse needs of farmers and improve production efficiency. Many drone companies are actively exploring agricultural solutions based on drone technology to jointly promote the development, innovation, and progress of global agriculture.

[0003] However, it still has some disadvantages. For example, when mixing pesticides, workers usually rely on experience to add the liquid medicine into the liquid medicine tank and mix it with water for application. When too much liquid medicine is added, the concentration of the liquid medicine in the mixture will be high, causing pesticide damage to plants. When less liquid medicine is added, it will not be able to disinfect pests and diseases, thus affecting the harvest. In addition, when the liquid medicine is blended, workers need to stir it manually or use a motor to drive the stirrer for stirring. Manual work is relatively time-consuming and labor-intensive, and electric stirring has certain limitations.

[0004] In order to solve the above problems, this application proposes a pesticide tank mixer for a crop protection drone. Utility Model Content
