Abstract

The invention provides a variable-rate spraying plant protection unmanned aerial vehicle equipped with variable-concentration pesticide preparation and pesticide application modules. The variable-ratespraying plant protection unmanned aerial vehicle comprises an unmanned aerial vehicle module, a vehicle-mounted power supply module, a vehicle-mounted control module, the vehicle-mounted pesticide preparation module and the vehicle-mounted pesticide application module. Compared with the prior art, the variable-rate spraying plant protection unmanned aerial vehicle has the following advantages: (1) effectively coping with big differences in disease index in different areas of an operation land block, following the principle of ''mild pesticides for mild disease and severe pesticides for severe disease'' to achieve ''variable-concentration'' pesticide application, and making up for the technical deficiencies of a ''variable-rate'' pesticide application unmanned aerial vehicle; (2) achieving the ''real-time and on-demand'' preparation of pesticide solutions with different concentrations during the flight operation of the plant protection unmanned aerial vehicle by adopting the two-tankindependent control output design with a water tank and a pure pesticide tank, and achieving the recovery and recycling of the remaining water and pesticides after the operation; (3) adopting a noveldesign of using a single-chip microcomputer to control two different mediums to perform the preparation of the pesticide solutions with different concentrations, achieving the advantages of good system responsiveness, high concentration accuracy and the like, and facilitating the popularization and application.

Description

technical field

[0001] The invention relates to a variable spraying plant protection drone equipped with a variable concentration dispensing and application module. More specifically, the plant protection drone can synchronously change the spraying rate according to the severity of diseases, insect pests and weeds in the target operation area. It belongs to the technical field of plant protection UAV equipment to improve the utilization rate of pesticides and realize precise operations. Background technique

[0002] my country has 7% of the arable land on the earth, but its chemical fertilizer consumption accounts for 38% of the global total. 95% of human food comes from the soil, and the low utilization rate of pesticides not only causes a lot of waste of resources, but also produces environmental pollution, and even produces phytotoxicity and pesticide residues on crops, and excessive pesticides will seep into the land and eventually enter the human body. Pesticides in fo...
