Abstract

The invention discloses a spray bar adjusting device of an unmanned aerial vehicle for plant protection and an adjusting method of the spray bar adjusting device. The spray bar adjusting device comprises a fixing plate and a spray bar, wherein the spray bar is provided with a spray nozzle, a positioning marker post is arranged on the fixing plate in a hung mode, the spray bar is horizontally arranged, and a width adjusting mechanism which is used for driving the spray bar to move to the left and right so as to realize adjustment of the width position of the spray nozzle is arranged on the spray bar; the width adjusting mechanism is mounted on a horizontal slide bar, and the fixing plate is fixedly provided with a telescopic mechanism which is used for making the horizontal slide bar to move up or down or incline so as to achieve adjustment of the height of the spray bar and the inclined angle of the spray bar; the telescopic mechanism comprises a first telescopic mechanism and a secondtelescopic mechanism which are arranged in an inverted V shape and can be independently controlled separately, and the spray bar adjusting device can be fixedly mounted on a landing rack of the unmanned aerial vehicle through the fixing plate. The adjusting method of the spray bar adjusting device includes a method for adjusting the height of the spray bar, a method for adjusting the width position of the spray nozzle and a method for adjusting inclination of the spray bar.

Description

technical field [0001] The invention relates to the technical field of agricultural and forestry aviation machinery, in particular to a spray boom adjustment device of an unmanned aircraft, in particular to a plant protection unmanned aircraft spray boom adjustment device and an adjustment method thereof. Background technique [0002] As an advanced spraying tool, the plant protection unmanned aerial vehicle has the advantages of high efficiency, fastness and adaptability to different terrains. When the current unmanned aircraft is spraying, the height of the spray boom, the position of the nozzle and the angle of the spray boom are generally fixed. [0003] When the plant protection unmanned aerial vehicle performs pesticide application, from the perspective of flight safety, the flight altitude should be kept at a more suitable altitude, and from the perspective of pesticide application effect, the flight altitude should be at a lower altitude. Regardless of whether the a...
