Profile variable sprayer and profile control method based on crown phenotype characteristics

Abstract

The invention discloses a profiling variable sprayer and a profiling control method based on tree crown phenotype characteristics. The profiling variable sprayer includes a profiling mechanism module A, a profiling mechanism module B, a lifting and sliding module, a profiling bracket module, a The hydraulic system, electrical box and detection module; on the basis of the function and mechanism division of the profiling variable sprayer, the modular and lightweight design is adopted. The whole machine has the characteristics of compact structure, lightness and flexibility, easy manufacture and easy maintenance. . The adaptive profiling control method of the profiling variable sprayer automatically collects the ultrasonic echo signal and processes it to obtain the phenotype characteristic information of the tree canopy, and then calculates the spray volume according to the phenotype characteristic parameters of the canopy volume and canopy leaf area density; through The profiling control amount calculated by the ultrasonic ranging information drives the profiling mechanism to profil the canopy contour automatically, with high profiling accuracy, precise and efficient spraying, less medicine and environmental protection, and easy operation.

Description

technical field [0001] The invention belongs to the field of sprayer intelligent equipment, and in particular relates to a profiling variable sprayer and a profiling control method based on tree crown phenotype characteristics. Background technique [0002] In recent years, my country's forestry industry has developed rapidly, and the planting area and production volume of various forest trees have increased year by year, such as fruit trees, street trees, landscape trees and other forest trees. In order to deal with the problem of forest pests and diseases, sampling and precise spraying technology is used to apply pesticides to trees, which can not only prevent pests and diseases, but also reduce pesticide residues and environmental pollution. [0003] At present, there are three mainstream spraying methods for sprayers. The boom sprayer is mainly used for the prevention and control of plant diseases and insect pests in field crops; the inverted U-shaped sprayer is mainly u...

Problems solved by technology

[0009] The technical problem to be solved by the present invention is aimed at the existing profiling sprayer. In terms of profiling mechanism, there are problems such as large and heavy mechanism, poor flexibility, high manufacturing difficulty and high production cost; in profiling control, manual control is generally used Profiling, there are problems such as poor profiling accuracy, difficult operation, and low efficiency. A profiling variable sprayer and profiling control method based on the phenotype characteristics of the crown is provided, wherein the profiling variable sprayer controls the profiling sprayer Based on the division of functions and mechanisms, the modular and lightweight design is adopted, and the whole machine has the characteristics of compact structure, lightness and flexibility, easy manufacture, easy maintenance and low production cost; among them, the profiling control method of the profiling variable sprayer is automatic Collect ultrasonic echo signals and process the tree canopy phenotype characteristic information, calculate the profiling control amount, drive the profiling mechanism to profiling, and realize the automatic profiling of the canopy contour, with high profiling accuracy, precise and efficient spraying, saving medicine and environmental protection , easy to operate
