Variable-spraying plant protection vehicle capable of automatically changing concentration of sprayed pesticides

Abstract

The invention provides a variable-spraying plant protection vehicle capable of automatically changing the concentration of sprayed pesticides. The variable-spraying plant protection vehicle comprisesa plant protection vehicle chassis module, a vehicle-mounted power module, a vehicle-mounted control module, a vehicle-mounted blending module and a vehicle-mounted spraying module. Compared with theprior art, the variable-spraying plant protection vehicle has the advantages that 'concentration-variable' spraying can be automatically realized during operation according to large disease index differences among different regions of an operation field and based on the principle of 'applying different pesticides according to different disease degrees'; due to the independent output control of 'awater tank plus a pure pesticide tank', the pesticides with different concentrations are blended 'in real time and according to needs' during operation of the variable-spraying plant protection vehicle, and residual water and pesticides can be recycled after operation; a single chip microcomputer is used for controlling two different media to be blended into the pesticides with the different concentrations, and the plant protection vehicle has the advantages of quick system response, high concentration accuracy and the like and is convenient to promote and apply.

Description

technical field [0001] The invention relates to a variable spraying plant protection vehicle with independently variable spraying concentration. More particularly, the plant protection vehicle can automatically change the concentration of the sprayed liquid according to the severity of diseases, insects and weeds in the target operation area. , so as to improve the utilization rate of pesticides and realize precise operations, belonging to the technical field of ground plant protection equipment. 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. Pestic...

AI Technical Summary

Problems solved by technology

[0004] However, the existing variable-variable spraying plant protection vehicle is a kind of "variable flow" pesticide application equipment after all. If the incidence index of different areas of the work 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-mentioned problems existing in the existing ground plant protection equipment
