摘　　要：针对4YZ—3型玉米联合收获机液压传动系统油温偏高、粮箱下降速度偏慢等问题,对4YZ—3型玉米联合收获机液压系统的各个子系统功能及相互之间的运行关系进行研究,分析传统液压系统存在的缺点,并提出相应解决方案。该方案在4YZ—3型玉米收获机进行试验,试验结果:系统运行8h,油温低于80℃,粮箱下落时间小于1min。试验证明方案有效可行。According to the problems of high oil temperature and slow falling speed of grain tank of the 4YZ-3 corn combine hydraulic system, the function of each subsystem and the operational relationship between each other were studied and analyzed. The shortcomings of the traditional system were discovered and the appropriate solutions were proposed, which were then tested in 4YZ-3 corn combine. The oil temperature was below 80 degrees after working 8 hours and the falling time of grain tank was less than a minute, which proves the solutions are effective and feasible.
