摘要
液压技术在采棉机上的应用实现了采棉机的自动化,采棉机的机械自动化可以提高采棉效率,节约成本.本文设计完成了采棉机液压系统,包括采棉头升降液压系统、棉箱翻转液压系统和采棉头液压驱动系统.利用AMESim软件建立采棉机液压系统模型,并进行了仿真分析,得到了采棉机液压系统的执行元件的仿真曲线.结果表明,采棉头液压马达负载偏差不宜太大,以保证采棉头正常高效作业.液压缸和液压马达运行平稳,输出参数稳定,设计的液压系统能够满足采棉作业使用要求.
The application of hydraulic technology on the cotton picker realizes the automation of the cotton picker. The mechanical automation of the cotton picker can improve the efficiency of cotton picking and save costs. This paper designed the hydraulic system of the cotton picker, including the cotton picking head lifting hydraulic system, the cotton box turning hydraulic system and the cotton picking head hydraulic drive system.The hydraulic system model of the cotton picker was established by AMESim software, and the simulation analysis was carried out. The simulation curve of the actuator of the hydraulic system of the cotton picker was obtained.The results show that the load deviation of the hydraulic motor of the cotton picking head should not be too large to ensure the normal and efficient operation of the cotton picking head. The hydraulic cylinder and hydraulic motor run smoothly, the output parameters are stable, and the designed hydraulic system can meet the requirements of cotton picking operation.
