Automatic adjusting device and method for boom balance

Abstract

The invention discloses an automatic adjusting device and method for boom balance. The mechanical portion of the device consists of a running chassis, a sprayer main rack, a boom, rollers, a lifting hydraulic cylinder and a balance adjustment hydraulic cylinder; the control portion of the device consists of an attitude sensor, a data acquisition device, a controller, a power amplification module and a reversing solenoid valve. Before operation of a boom sprayer performs operation, the boom can be adjusted to proper operating height through the lifting hydraulic cylinder. In the operation of the boom sprayer, the controller predicts the adjustment amount needed by the hydraulic cylinder for leveling the boom according to the lateral inclination angle and lateral inclination angle acceleration of the running chassis measured by the attitude sensor installed on the running chassis and sends out a control signal to adjust the balance of the boom in advance. The distribution uniformity of spray drops and the adhering performance of the spray drops are improved, the pesticide is saved and the environmental pollution is reduced. The automatic adjusting device and method for boom balance can be applied to boom sprayers.

Description

Technical field [0001] The invention belongs to the field of plant protection machinery, and particularly relates to an automatic adjustment device and method for spray rod balance. Background technique [0002] When the boom sprayer is in operation, the irregular movement of the boom in the vertical direction will greatly reduce the uniformity of spray distribution. This non-uniformity will cause the pesticide residues of the crops in the overspray area to exceed the standard, and the crops at the missed spray area will suffer disease. Disasters such as caterpillar fungus. In order to ensure the normal growth of crops, the method of increasing the amount of pesticides is often used to make up for this deficiency, which not only causes waste of pesticides, but also causes environmental pollution. At the same time, irregular movement of the spray rod in the vertical direction may also cause the end of the spray rod to touch the ground and cause damage to the sprayer. Therefore, ...

AI Technical Summary

Problems solved by technology

However, the above-mentioned spray boom balance automatic adjustment device directly adjusts the balance of the spray boom by detecting the attitude of the spray boom, and the adjustment speed is relatively slow.

[0004] However, the irregular movement of the boom of the boom sprayer in the vertical direction is often caused by the change of the posture of the driving chassis.
