Pesticide spraying plant protection unmanned aerial vehicle

Abstract

The invention relates to a pesticide spraying plant protection unmanned aerial vehicle. The pesticide spraying plant protection unmanned aerial vehicle comprises an outer frame, a water inlet controldevice, swinging devices and an opening and closing cover, the water inlet control device is installed inside the outer frame, the swinging devices are uniformly arranged on the outer wall of the outer frame, and the swinging devices are connected with the water inlet control device; the opening and closing cover is arranged at the upper end of the outer frame, and an unmanned aerial vehicle bodyis connected with the water inlet control device in a threaded mode. According to the pesticide spraying plant protection unmanned aerial vehicle, the difficult problems that during pesticide sprayingof existing unmanned aerial vehicles, nozzles are usually arranged fixedly, thus the spraying range is limited, part of agriculture and forestry plants may not be sprayed, and spraying cannot be controlled according to the actual situation can be solved, the water inlet control device adopts an injection-type piston principle to control water sources of first nozzles and second nozzles, thus theconcentration of pesticide spraying during operating is controlled, and the first nozzles and the second nozzles in the swinging devices swing synchronously through a four-bar mechanism principle, andconduct reciprocating swinging under driving of reciprocating air cylinders, so that the spraying range is expanded.

Description

technical field [0001] The invention relates to the field of drone spraying, in particular to a pesticide spraying plant protection drone. Background technique [0002] Plant protection UAV, also known as unmanned aerial vehicle, as the name implies, is an unmanned aircraft used for agricultural and forestry plant protection operations. Composed of three parts, the spraying operation is realized through ground remote control or navigation flight control, which can spray chemicals, seeds, powders, etc. Among them, the water replenishment of agricultural and forestry plants is usually sprayed with aerial pesticides by means of plant protection drones. However, now Some pesticide spraying devices often have the following problems: when spraying pesticides, the nozzles are usually fixed, which limits the spraying range, and some agricultural and forestry plants may not be sprayed, and the amount of pesticide spraying cannot be controlled according to the actual situation during ...

AI Technical Summary

Problems solved by technology

[0004] The present invention can solve the problem that the nozzles are usually fixed when the pesticide is sprayed by the existing UAV, which limits the spraying range, and some agricultural and forestry plants may not be sprayed, and the amount of pesticide spraying cannot be controlled according to the actual situation during operation, thus affecting the spraying of pesticides quality and other problems
