Abstract

The invention discloses a spray bar balance active prediction adjustment system and method, and relates to the field of plant protection machinery. A mechanical part comprises a driving chassis, an atomizing machine main frame, a spray bar, a rolling column, branchers, a spray bar lifting hydraulic cylinder, a left side balance hydraulic cylinder, a right side balance hydraulic cylinder, a left transverse folding hydraulic cylinder and a right transverse folding hydraulic cylinder; a control part includes a chassis attitude sensor, multi-dimensional force sensors, a data acquisition module, aspray bar balance controller, a data output module and a solenoid valve; an atomizing spray bar is provided with a plurality of branchers, each of the branchers is provided with the multi-dimensionalforce sensors to detect random branch resistance, and the chassis attitude sensor is mounted on the driving chassis to detect the posture change and the trend. During the actual field operation of anatomizing machine, the spray bar balance controller predicts the change amount of spray bar postures according to the random branch resistance of each brancher and the posture change and trend of thedriving chassis, and the balance hydraulic cylinders on both sides are controlled to conduct servo-predictive control on the spray bar.

Description

technical field [0001] The invention belongs to the field of plant protection machinery, and in particular relates to a system and method for actively predicting and adjusting spray boom balance. Background technique [0002] During the field operation of the boom sprayer, the boom not only has to bear the ground bumps transmitted by the driving chassis, but also bears the random branch resistance of each branch due to the existence of the branch, which is very prone to boom deflection and The shaking of the spray boom not only affects the uniformity of spraying, but may even cause serious accidents such as scratching crops, touching the spray boom to the ground, and breaking the spray boom. Therefore, it is of great practical significance to develop an automatic adjustment system for spray boom balance. [0003] Patent application number 201510079249.0 discloses a spray boom balance automatic adjustment device and method. During operation, the controller predicts the hydra...
