Balance control device of spray boom of high ground clearance boom sprayer and control method of balance control device

Abstract

The invention discloses a balance control device of the spray boom of a high ground clearance boom sprayer and a control method of the balance control device. The balance control device comprises a balance control system, wherein the balance control system comprises components such as a controller, an electromagnetic damper and sensation equipment. When the controller judges that the spray boom moves downwards according to detection signals of the sensation equipment, the electromagnetic damper is controlled to generate damping force for obstructing the rotor of the spray boom to rotate, and according to movement states of the spray boom, the damping force of the electromagnetic damper is adjusted in a soft stopping mode, so that vibration of the spray boom tends to be stable; and when thecontroller judges that the spray boom moves upwards, power supply current of the electromagnetic damper is cut off, and then the electromagnetic damper does not generate the damping force till the speed that the spray boom moves upwards is turned into zero. By adopting the device and the control method of the device disclosed by the invention, the balance stability of the spray boom of the high ground clearance boom sprayer in operation can be effectively improved, and the device is precise in control, reasonable in structure planning, easy to manufacture, implement and maintain and applicable to popularization and application.

Description

technical field [0001] The invention relates to the technical field of agricultural plant protection machinery, and relates to a spray boom arm balance control device and method, in particular to a spray boom arm balance control device and a control method for a high clearance spray boom sprayer. Background technique [0002] As a mainstream plant protection equipment, the high clearance boom sprayer has the advantages of high efficiency, quickness and adaptability to different fields. As the main working part of the high ground clearance boom sprayer, the boom arm has the characteristics of long arm span and great flexibility. However, when the high-ground-clearance boom sprayer is working, the boom arm has a long arm span and poor stability, and is easily affected by the swing of the body and terrain changes, resulting in Roll motion and vibration in the vertical direction. A small vibration amplitude may cause the end of the boom arm to vibrate greatly, affecting the bal...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the following problems in the prior art, that is, when the current high-ground-clearance boom sprayer is working, the length of the boom arm is fixed due to the fixed length of the cable, which causes an emergency stop when the vibration is reset, resulting in greater secondary vibration, which seriously affects The effect of pesticide application

The invention provides a balance control device and control method for the boom arm of a high ground clearance boom sprayer that can solve or improve the above problems
