Self-adjustment spraying frame for agricultural unmanned aerial vehicle

Abstract

The invention discloses a self-adjustment spraying frame for an agricultural unmanned aerial vehicle. The self-adjustment spraying frame involves an unmanned aerial vehicle body and further comprisesa water tank and rotor wings, and the water tank and the rotor wings are arranged on the unmanned aerial vehicle body. At least one transverse pipe in horizontal arrangement is fixedly connected to the bottom end of the unmanned aerial vehicle body and communicated with the water tank through a connection pipe, and a valve is mounted on each connection pipe. Sleeves in hollow structures are vertically arranged at lower ends of the rotor wings. By modification of a traditional fixed spraying frame into an initiative structure, dynamically-adjustable spraying can be performed on low-altitude trees and minimum-altitude vegetations under the action of wind, and as for tall trees, vertical height difference can be formed among multiple nozzles, and droplets are sprayed deep among leaf layers under the action of gravity or wind; when relatively low and close-to-ground vegetations are sprayed, the multiple nozzles are on a same horizontal plane approximately to realize a maximal spraying range. In addition, electric power is avoided in adjustment, so that endurance of the agricultural unmanned aerial vehicle is improved indirectly, and energy saving and environmental friendliness are realized.

Description

technical field [0001] The invention relates to the technical field of agricultural drones, in particular to an agricultural drone self-adjusting spraying frame. Background technique [0002] When the agricultural drone sprays the liquid medicine, it is affected by the height and the wind. The higher the altitude, the more likely the drift will occur. The sprayed liquid medicine will drift. When the drifting liquid medicine flies over the field pond, it may harm aquatic organisms. , if a large amount of chemicals fall into the water source, it may also cause safety accidents. In the traditional technology, the nozzles of agricultural drones are usually centrifugal nozzles and pressure nozzles, which are installed on the bottom bracket of agricultural drones. Since the bracket adopts a fixed type Therefore, the spraying height and angle cannot be adjusted, so that it cannot be dynamically adjusted for crops of different heights, so it is urgently needed to change.
