Rotary wing type unmanned aerial vehicle for spraying pesticides

Abstract

The invention relates to a rotary wing type unmanned aerial vehicle for spraying pesticides. The rotary wing type unmanned aerial vehicle comprises a vehicle body with a rotary wing component, wherein a plurality of pesticide boxes and a pesticide spraying device connected with the pesticide boxes are further mounted on the vehicle body; all the pesticide boxes are flatly arranged and the whole horizontal gravity center coincides with the horizontal gravity center of the vehicle body. According to the rotary wing type unmanned aerial vehicle for spraying pesticides disclosed by the invention, a large pesticide box is divided into a plurality of small pesticide boxes with the same size, so that the inertia of pesticide liquid inside a single pesticide box can be reduced, the horizontal center-of-gravity shift generated by the liquid inside each pesticide box is relatively small under the condition that the aerial vehicle suddenly stops, the overall horizontal center-of-gravity shift is greatly smaller than that under the condition that the single pesticide box is filled with the pesticide liquid, and thus the problem that flight control cannot correct out-of-control falling caused by too large horizontal center-of-gravity shift and too large dip angle of the vehicle body is avoided.

Description

technical field [0001] The invention relates to the application of a rotary-wing unmanned aerial vehicle, in particular to a rotary-wing unmanned aerial vehicle for spraying pesticides. Background technique [0002] In agricultural production, the control of pests and weeds has always been an important issue. For a long time, the control of rice pests and weeds has mainly relied on manual sprayers and knapsack motorized sprayers. Adapting to the requirements of rapid and effective control of major outbreaks of diseases, insect pests and weeds has also become the main technical bottleneck restricting the realization of the goal of rice mechanization. [0003] The use of drones to spray pesticides is an effective means to solve the special field operation conditions of rice fields, but the conventional fixed-wing aircraft spraying technology has a high operating height, a large drift distance of droplets, and the location and time of use are greatly restricted. Suitable for p...
