Method of adjusting plant protection spraying system of single-rotor agricultural unmanned aerial vehicle

Abstract

The invention discloses a method of adjusting a plant protection spraying system of a single-rotor agricultural unmanned aerial vehicle and belongs to the technical field of plant protection by agricultural unmanned aerial vehicles. The method includes the steps of under certain temperature and humidity conditions, determining maximum spray height H1, 3m to 5m, according to evaporation parameter and a test to obtain effective spraying swath X while a nozzle is horizontal; comparing operational temperature and humidity to the temperature and humidity under the measurement conditions in the step A, and adjusting spraying height H2 and nozzle inclination angle Delta when operation is determined. During adjusting, the higher the temperature, the less the spraying height H2 corresponding to the operation; the higher the humidity, the greater the spraying height H2 corresponding to the operation. The method has the advantages that operating efficiency is improved, spraying quality and spraying effect are guaranteed, pesticide residue safety can also be guaranteed for crops and the method is suitable for popularization and application for higher efficiency of unmanned aerial vehicle based plant protection.

Description

technical field [0001] The invention relates to a spraying system adjustment method, in particular to a single-rotor agricultural unmanned aerial vehicle plant protection spraying system adjustment method, which belongs to the technical field of agricultural unmanned aerial vehicle plant protection. Background technique [0002] Agricultural drone plant protection technology has been widely used in the field of agricultural plant protection due to its advantages of simple operation, high work efficiency, and good spraying effect. When agricultural drone spraying operations, in order to achieve good technical results, it is required to spray pesticides It can reach the surface of the crops to the greatest extent, and it is not allowed to drift halfway. If this happens, it will lead to poor plant protection effect, waste of pesticides, and pollution of the fuselage and the environment due to the spraying operation. When working under different climatic conditions, generally ch...

[0002] Agricultural drone plant protection technology has been widely used in the field of agricultural plant protection due to its advantages of simple operation, high work efficiency, and good spraying effect. When agricultural drone spraying operations, in order to achieve good technical results, it is required to spray pesticides It can reach the surface of the crops to the greatest extent, and it is not allowed to drift halfway. If this happens, it will lead to poor plant protection effect, waste of pesticides, and pollution of the fuselage and the environment due to the spraying operation. When working under different climatic conditions, generally choose windless weather to work, but the temperature and humidity of the air vary greatly during each operation. Under a certain spraying height, the temperature and humidity will affect whether the pesticide can reach the crop surface smoothly and normally. The optimal time for the spray to reach the crop surface should be different under different temperature and humidity. This time is mainly related to the distance from the nozzle to the crop surface. The larger the distance,
