Spraying-width-adjustable spraying device for plant protection unmanned aerial vehicle

Abstract

The invention relates to a spraying-width-adjustable spraying device for a plant protection unmanned aerial vehicle. The spraying device comprises a pesticide box, and a shell is arranged above the pesticide box; the first pipe body is slidably arranged in the shell in the horizontal direction, and a plurality of spray heads are arranged at the bottom of the first pipe body; a fixed part of the linear displacement assembly is connected with the shell, and a movable part is connected with the first pipe body; the pump body is arranged in the shell, a water inlet pipe of the pump body extends into the pesticide box, and a water outlet pipe is connected with one end of the first pipe body through a telescopic pipe; the first water pipe is made to move by arranging the linear displacement assembly, the extending length of the first water pipe can be adjusted according to the boundary line of a planting area, the unmanned aerial vehicle runs linearly, pesticide can be evenly sprayed to plants, the driving mechanism is arranged on the back faces of teeth, the teeth are rotated to be flat, meshing with the gear is disconnected, and the pesticide can be sprayed to the plants evenly. The length of the first water pipe on one side can be adjusted, the other side sprays along a straight line, and when a next line is sprayed, the two sides keep spraying along the straight line, and spraying can be even.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery and equipment, in particular to a spray device with adjustable spray width for plant protection drones. Background technique [0002] Agricultural planting generally requires regular spraying of pesticides, etc. At present, pesticide spraying is basically carried out by manually operating the spraying head. Since the spraying device needs to continuously provide pesticides, it is generally relatively cumbersome, and when the planting area is large, manual use is more laborious. . [0003] In the prior art, when spraying pesticides on a large area of ​​​​planting, it is often sprayed by drones. However, the plant protection drone spraying device is usually provided with multiple nozzles, and the multiple nozzles are arranged in a circular arrangement or a straight line. The width of the spray cannot be adjusted according to the width of the planting area or the shape of the planting...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that when one edge of the spraying area is a curve, if the driving path of the existing drone is controlled to be a curve, some plants will be repeatedly sprayed, and some positions cannot be sprayed.
