Pesticide spraying device for unmanned aerial vehicle

Abstract

The invention discloses a pesticide spraying device for an unmanned aerial vehicle. The pesticide spraying device comprises a machine body, a conveying pump and liquid drug boxes, wherein a spraying pipe is connected with a liquid outlet of the conveying pump; two liquid drug boxes are arranged; the two liquid drug boxes are respectively fixedly welded in a left foot bracket and a right foot bracket of the machine body; a cross beam is arranged between the left foot bracket and the right foot bracket of the machine body; the conveying pump is mounted on the middle part of the cross beam; a first liquid pumping straight pipe is arranged on a first liquid drug box; a first hose leading to the bottom of the first liquid drug box is connected with the first liquid pumping straight pipe; a second liquid pumping straight pipe is arranged on a second liquid drug box; a second hose leading to the bottom of the second liquid drug box is connected with the second liquid pumping straight pipe; a liquid pumping pipe of the conveying pump is simultaneously connected with the first liquid pumping straight pipe and the second liquid pumping straight pipe through a tee-joint pipe. According to the invention, the volume of the space structure of the unmanned aerial vehicle is reduced and the unmanned flying loss is reduced; the operation of frequently repeatedly loading liquid drug is not required and the time is saved; the unmanned aerial vehicle has better balancing property during a flying process and can stably and reliably fly.

Description

technical field [0001] The invention relates to the technical field of modern agricultural equipment, in particular to a pesticide spraying device for an unmanned aerial vehicle. Background technique [0002] In modern agriculture, in order to suppress crop diseases, insects, and weed damage, it is necessary to spray pesticides on crops. For small crops, ordinary manual spraying equipment is more cost-effective, but for vast crops on the plains, it is often necessary to use drones to spray pesticides. When traditional UAVs spray pesticides, it is often necessary to install liquid medicine tanks, delivery pumps and spray pipes on the side walls of the UAV body. This structure has the following defects: [0003] 1. The space structure of the UAV is relatively large, which makes the UAV encounter greater air resistance during flight, which increases the loss of unmanned flight; [0004] 2. The liquid medicine tank can be loaded with less liquid medicine, which requires freque...

AI Technical Summary

Problems solved by technology

[0003] 1. The space structure of the UAV is relatively large, which makes the UAV encounter greater air resistance during flight, which increases the loss of unmanned flight;

[0004] 2. The liquid medicine tank can be loaded with less liquid medicine, which requires frequent repeated loading of liquid medicine, wasting too much time;

[0005] 3. The structure is scattered and the center of gravity deviates greatly, which makes the balance of the UAV poor when flying
