Embodiment Construction

[0026] Such as figure 1 and 2 Shown, the rotor type unmanned aerial vehicle that is used to spray pesticides of the present embodiment comprises: the fuselage 2 that has rotor assembly 1 and the medicine box 4 that is installed on the fuselage, the fuselage 2 includes the medicine box 4 that is used to install The support 3 and the spraying device 5 connected with the medicine box 4, the center of the support 3 is hollowed out to reduce the mass at the center of the fuselage.

[0027] There are multiple medicine boxes 4, and all the medicine boxes 4 are arranged in a tiled manner and the overall horizontal center of gravity coincides with that of the fuselage 2. The arrangement of a plurality of medicine boxes can be uneven, but for the convenience of installation, in the present embodiment, all medicine boxes 4 are evenly distributed along the circumference, and the horizontal center of gravity of all medicine boxes 4 whole falls on its geometric center. A plurality of medi...

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...
