Abstract

The invention discloses a self-pressurization type spraying device for a plant protection unmanned aerial vehicle. The device comprises an unmanned aerial vehicle body and a mounting box arranged below the unmanned aerial vehicle body, a water tank is connected into the mounting box through a reinforcing rod, a stirring mechanism is arranged on the mounting box, and a pressurization mechanism connected with the stirring mechanism is arranged in the water tank; a hollow rod communicating with the pressurization mechanism is rotatably arranged at the bottom of the pressurization mechanism, the end, penetrating to the bottom of the mounting box, of the hollow rod is connected with an annular spraying pipe communicating with the hollow rod, and a driving mechanism for driving the hollow rod torotate is arranged in the mounting box; through the arrangement of the stirring mechanism and the pressurization mechanism, the stirring mechanism enables liquid medicine and water to be sufficientlymixed, the pressurization mechanism is used for pressurizing, so that the liquid medicine is sprayed out from a lower nozzle of the annular spraying pipe, the influence of wind power on the liquid medicine in the spraying process is reduced, the spraying effect is improved, a pressurizing element does not need to be additionally arranged, and the production cost is reduced; and by arranging the driving mechanism, the annular spraying pipe continuously rotates in one direction, and therefore the spraying range of the spraying device is enlarged.

Description

technical field [0001] The invention relates to the technical field of drones, in particular to a self-pressurized spraying device for plant protection drones. Background technique [0002] UAVs can be divided into military and civilian use according to the application field. In terms of civilian use, the application of UAV industry is the real just-needed plant protection UAV of UAV, and it is the application of civilian UAV in agricultural and forestry plant protection operations. The main working mode is to fly with the medicine box and spray the medicine liquid downward to ensure the plant protection operation in a specific area. [0003] When the existing spraying device for plant protection drones sprays agricultural and forestry plants, the sprayed liquid medicine is often affected by the wind force, which makes it impossible to spray the designated area, resulting in poor spraying effect and waste of liquid medicine. To solve the problem, a self-pressurized spraying...
