A pesticide spraying unmanned aerial vehicle with multiple spraying heads

Abstract

The invention discloses a pesticide spraying unmanned aerial vehicle with multiple spraying heads. The unmanned aerial vehicle comprises a pesticide storage box; the pesticide storage box is fixed onthe top surface of a mainframe box in a flat type covering and pressing manner; a plurality of anti-surge plates are vertically fixed to the inner top of the pesticide storage box side by side; a storage groove with a downward opening is formed in the bottom surface of a motor bracket; one end of a rotary pesticide spraying pipe is rotationally fixed in the storage groove through a rotary drivingdevice; the rotary pesticide spraying pipe is communicated with a rotary feeding device arranged in the mainframe box, a piston device used for separating the interior of the rotary pesticide sprayingpipe is arranged in the rotary pesticide spraying pipe, and a traction device used for pulling the piston device is arranged on the inner wall of the storage groove. According to the unmanned aerialvehicle, the arranged rotary pesticide spraying pipe can rotationally stretch out to spray pesticide; the pesticide spraying range of the rotary pesticide spraying pipe is automatically adjusted whilethe pesticide spraying angle of the rotary pesticide spraying pipe is adjusted; a control device does not need to be additionally arranged, the spraying head and the rotary pesticide spraying pipe are mutually matched for use, and the unmanned aerial vehicle pesticide spraying applicability and the pesticide spraying efficiency are greatly improved.

Description

technical field [0001] The invention relates to an agricultural spraying device, in particular to a pesticide spraying unmanned aerial vehicle with multiple spraying heads. Background technique [0002] Pesticide spraying drone is also called plant protection drone, also known as unmanned aerial vehicle. As the name implies, it is an unmanned aircraft used for agricultural and forestry plant protection operations. ), navigation flight control, and spraying mechanism. The spraying operation is realized through ground remote control or navigation flight control. It can spray chemicals, seeds, powder, etc. The pesticide spraying drone has low operating height, less drift, and can be suspended in the air. There is no need for a special take-off and landing airport, spraying operators avoid the danger of being exposed to pesticides, and improve the safety of spraying operations. 90% water consumption, which will greatly reduce resource costs. Compared with oil-powered drones, el...

Problems solved by technology

[0003] At present, the pesticide spraying drones on the market are generally equipped with different types of spraying drones according to the different crops to be sprayed. For some environments such as large-scale evenly planted rice fields, the downward spraying method is generally used. For some plant-like fruit trees, in order to ensure the spraying effect of a single fruit tree, it is generally sprayed in a single-point form with a nozzle that can extend into the branches of the fruit tree. This type of protruding nozzle may easily cause the main body of the drone to Decreased stability is not suitable for long-distance moving and uniform spraying of drones, so these two types of nozzles are generally installed separately on different types of drone bodies, and these nozzles with rotation or extended length can generally be used Adjust the angle, but the spraying range, length, and area are not easy to adjust. Some spray heads with spraying range adjustment need to add additional control devices, which will increase the overall quality of the drone, reduce the working time under the same battery capacity, and reduce the spraying efficiency. , and these nozzles with rotation and extension are not easy to store, and they are easy to affect the take-off and landing of the UAV, resulting in increased difficulty in the maneuverability of the UAV and reduced practicability. Therefore, in view of the above problems, we need a The stable and efficient spraying drone device
