Plant protection unmanned aerial vehicle capable of spraying uniformly and using method thereof

Abstract

The invention belongs to the field of unmanned aerial vehicles, and particularly relates to a plant protection unmanned aerial vehicle capable of spraying uniformly. The plant protection unmanned aerial vehicle comprises a rack, wherein wings are symmetrically arranged on the rack; the rack is fixedly connected with a pesticide box; a liquid discharging pipe is arranged at one end, far away from the wings, of the pesticide box; the liquid discharging pipe is detachably connected with a plurality of groups of nozzles; an adjusting piece is arranged above the liquid discharging pipe and directlyfaces the nozzles in a matching manner; a plurality of groups of movable grooves are formed in the liquid discharging pipe and matched with the adjusting piece; the movable grooves are connected withpressing blocks in a sliding manner; and the pressing blocks are connected with the adjusting piece through piezoelectric patches in a matching manner. According to the plant protection unmanned aerial vehicle capable of automatically adjusting the pesticide spraying amount, the uniformity of the unmanned aerial vehicle in the pesticide spraying process is effectively improved, particularly in the process that the unmanned aerial vehicle inclines or turns, the phenomenon that the pesticide exceeds the standard due to the fact that the pesticide spraying is too concentrated can be avoided, andthe pesticide spraying effect of the unmanned aerial vehicle is improved.

Description

technical field [0001] The invention belongs to the field of unmanned aerial vehicles, and in particular relates to a uniform spraying plant protection unmanned aerial vehicle and a method for using the same. 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. This type of unmanned aircraft consists of three parts: a flying platform, a navigation flight control and a spraying mechanism. Control, to achieve spraying operations, you can spray chemicals, seeds, powder and so on. The UAV has low height, less drift, can hover in the air, and does not need a special take-off and landing airport. The downward airflow generated by the rotor helps to increase the penetration of the fog to the crops, and the control effect is high. Remote control operation, spraying Operators avoid the danger of exposure to pesticides, improve the safety ...

AI Technical Summary

Problems solved by technology

The UAV has low height, less drift, can hover in the air, and does not need a special take-off and landing airport. The downward airflow generated by the rotor helps to increase the penetration of the fog to the crops, and the control effect is high. Remote control operation, spraying Operators avoid the danger of exposure to pesticides, improve the safety of spraying operations and many other advantages, and are widely used in the field of agricultural spraying. However, with the rapid development of agricultural construction, the shortcomings of drones in actual use are also urgently needed. to be perfect

[0003] In the prior art, the plant protection UAV mainly conducts the flight operation of the UAV manually in the process of spraying the medicine, but there is inevitably the problem of uneven spraying of the medicine during the manual operation, especially in the During the turning process of the UAV, due to the uneven spraying density of the UAV, a large amount of drugs are concentrated in local areas, which in turn causes the phenomenon of excessive pesticides, which easily causes the withering and death of crops and reduces the growth effect of crops.
