Manned plant protection aircraft realizing variable pesticide application concentration in working process

Abstract

The invention provides a manned plant protection aircraft realizing variable pesticide application concentration in a working process. The manned plant protection aircraft comprises a manned aircraftmodule, an airborne power supply module, an airborne control module, an airborne pesticide dispensing module and an airborne pesticide application module. Compared with the prior art, the manned plantprotection aircraft has advantages as follows: (1), the manned plant protection aircraft capable of effectively dealing with larger disease index difference of different areas of a working land parcel, conforming to the principle of lower pesticide application for mild diseases and heavier pesticide application for severe diseases and realizing variable-concentration pesticide application in theoperation process is provided, and defects of the manned plant protection aircraft realizing variable-flow pesticide application are overcome; (2), with adoption of water tank and pure pesticide tankdouble-tank independent control output design, real-time and on-demand blending of pesticide liquids of different concentrations in the flight operation process of the manned plant protection aircraftis realized; (3), the novel design of adopting a single chip microcomputer to control two different media for blending the pesticide liquids with different concentrations has the advantages of good system responsiveness, high concentration accuracy and the like and is convenient to popularize and apply.

Description

technical field [0001] The invention relates to a manned plant protection aircraft with variable application concentration during operation. More particularly, the manned plant protection aircraft can synchronously change the pesticides to be sprayed according to the severity of diseases, insect pests and weeds in the target operation area. It belongs to the technical field of manned plant protection aircraft 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. Pestici...

Problems solved by technology

[0004] However, the existing variable-variable spraying plant protection machinery is a kind of "variable flow" pesticide application equipment after all. If the disease index in different areas of the operation plot is very different, the pesticide application equipment will have "excessive control of minor diseases and prevention of major diseases." Insufficient" problem, it is urgent to follow the principle of "light medicine for mild disease, heavy medicine for severe disease" to develop a "variable concentration" pesticide application equipment to solve the above problems existing in the existing technical equipment

In recent years, manned plant protection aircraft has been favored by the industry for its high operating efficiency and wide operating coverage, but the accuracy and quality of operations need to be improved
