Marking mechanism of large unmanned aerial vehicle for forest farm nursery stock inspection

Abstract

The invention relates to the technical field of unmanned aerial vehicle marking, and in particular, relates to a marking mechanism of a large unmanned aerial vehicle for forest farm nursery stock inspection, wherein the marking mechanism comprises an unmanned aerial vehicle body; a driving mechanism is mounted on the unmanned aerial vehicle body, and a protection mechanism for protecting propellers is mounted on the driving mechanism; and a pesticide spraying mechanism for treating plant diseases and insect pests is mounted on the protection mechanism, two limiting mechanisms are oppositely arranged on the pesticide spraying mechanism, two reinforcing mechanisms are oppositely arranged on the pesticide spraying mechanism, the protection mechanism abuts against the reinforcing mechanisms, and a marking mechanism for positioning and marking the positions of the plant diseases and insect pests is mounted on the unmanned aerial vehicle body. The driving mechanism is mounted on the unmanned aerial vehicle body, when the unmanned aerial vehicle lands, the driving mechanism controls the protection mechanism to be opened without protecting the propellers, at the moment, the protection mechanism makes contact with the ground, the stability of the landing state of the unmanned aerial vehicle is improved, and when the unmanned aerial vehicle body inspects nursery stocks, the driving mechanism controls the protection mechanism to protect the propellers.

Description

technical field [0001] The invention relates to the technical field of UAV marking, in particular to a marking mechanism of a large UAV for seedling inspection in forest farms. Background technique [0002] Unmanned aircraft, referred to as "unmanned aerial vehicle", is an unmanned aircraft controlled by radio remote control equipment and its own program control device, or is completely or intermittently operated autonomously by the on-board computer. When you need to use a marking mechanism for large-scale unmanned aerial vehicles for forest seedling inspections, for example, the patent number is: 201610763089.6 patent, and the abstract part of the specification records: the GPS positioning module is used to obtain the GPS positioning information of the unmanned aerial vehicle. The GPS positioning information of the drone is transmitted to the data processing module; the GPS differential unit is used to differentially process the GPS positioning information of the drone to ...

AI Technical Summary

Problems solved by technology

[0003] However, if the current large-scale UAVs for seedling inspections in forest farms find that the seedlings have diseases and insect pests during the inspection, they can only mark the coordinates of the seedlings with diseases and insect pests through the marking mechanism. No spraying equipment is installed on the inspection UAV. After all the positions are out, it is necessary to replace the drone with spraying medicine for spraying. It is difficult to control the pests and diseases in time, which is not conducive to the growth of seedlings; and if the inspection drone inspects the seedlings with floating catkins, There is no protective mechanism at the propeller of the UAV. During the flight, the floating fluff easily enters the rotating part of the propeller, causing jamming and affecting the rotation of the propeller. The marking mechanism can be quickly taken out only when the UAV is placed at an angle, which is inconvenient to operate and affects the replacement and maintenance of the marking mechanism
