Mooring type agricultural unmanned aerial vehicle rubber tree floating-reducing pesticide applying system and pesticide applying method

Abstract

The invention discloses a mooring type agricultural unmanned aerial vehicle rubber tree floating-reducing pesticide applying system and method. The system comprises an unmanned aerial vehicle and an unmanned vehicle, and a spraying device is hung at the lower part of the unmanned aerial vehicle; a mooring cable for conveying electric energy to the unmanned aerial vehicle and conveying liquid pesticide to the spraying device is arranged between the unmanned vehicle and the unmanned aerial vehicle; the spraying device comprises an annular air curtain auxiliary pesticide applicator, the annular air curtain auxiliary pesticide applicator is composed of a pesticide spraying inner circular ring and an air spraying outer circular ring, and the pesticide spraying inner circular ring is fixedly connected with the air spraying outer circular ring; a plurality of aviation nozzles for spraying liquid pesticide are arranged on the pesticide spraying inner circular ring; the air spraying outer circular ring is communicated with an air blowing device, a plurality of air spraying holes distributed in the circumferential direction are formed in the air spraying outer circular ring, and the air outlet direction of the air spraying holes is the same as the axis direction of the air spraying outer circular ring. The system and method can continuously and effectively perform accurate spraying operation on a rubber forest with high and straight tree bodies, and can reduce drifting of fog drops.

Description

technical field [0001] The invention relates to an unmanned aerial vehicle pesticide application system and a pesticide application method, in particular to a tethered agricultural drone rubber tree drift reduction pesticide application system and a pesticide application method. Background technique [0002] Rubber is widely used in various fields such as industry, national defense, transportation, medicine and health because of its good insulation, elasticity and plasticity, and has the advantages of water-proof, gas-proof, wear-resistant and tensile-resistant. important resource. With the development of the economy, the social demand for rubber products is also expanding. There are 112 kinds of diseases and 182 kinds of insects recorded on rubber trees in my country. The diseases and insect pests that cause serious impact mainly include powdery mildew, anthracnose, red root disease, brown root disease and other diseases, as well as insect pests such as E. . The annual lo...

Problems solved by technology

Because the canopy is too high, it is difficult to use ground machinery or manual spraying to prevent and control pests and diseases

If a small UAV is used for aerial spraying operations, there will be a problem of high density of trees, which will limit the flying operation space of the aircraft. At the same time, due to the limited battery power of the UAV, the small amount of drug loading and the high requirements for the intensive spraying of rubber tree crowns, There is also the problem of low efficiency of drone rubber tree pesticide application

In addition, drones generally fly on the upper part of the canopy, and the nozzles are installed horizontally on the belly of the drone. Spraying rubber trees with such a nozzle arrangement usually results in the lower part of the rubber tree canopy and The drug application effect on the back of the leaf is poor, which in turn affects the control effect
