摘  要:针对丘陵山区三七收获劳动强度大、效率低及成本高等问题,开展自走式三七联合收获机液压系统研究。首先,对整机关键工作部件的液压系统进行理论分析、计算与设计,完成了液压元件选型。然后,利用AMESim软件建立液压系统仿真模型,开展各液压元件工作状态仿真分析,验证了液压系统设计方案的可行性。最后,制造样机并开展田间试验,完成了对整机液压系统工作性能的测试。试验结果显示:驱动一级升运链、振动轮、二级升运链与提升装置的液压马达的平均转速偏差分别为1.15%,2.05%,5.10%,4.09%;升降、倾角调节与倾卸液压缸的平均收回同步偏差率分别为0.63%,1.16%,0.62%,平均收回锁止偏差率分别为0.34%,0.66%,0.33%;倾卸液压缸的平均伸出同步偏差率与平均伸出锁止偏差率分别为0.56%,0.30%。结果表明,所设计的液压系统满足自走式三七联合收获机的作业要求,可为丘陵山区根茎类联合收获机液压系统的设计提供理论基础与参考。Aiming at the problems of high labor intensity,low efficiency and high cost of Panax notoginseng harvesting in hilly and mountainous areas,the hydraulic system of the self-propelled Panax notoginseng combine harvester was studied.Firstly,the hydraulic system of the key working components of the whole machine was theoretically analyzed,calculated and designed,and the selection for hydraulic components was completed.Then,the hydraulic system simulation model was established by AMESim software,and the simulation analysis for the working state of each hydraulic component was carried out to verify the feasibility of the hydraulic system design scheme.Finally,a prototype was manufactured and the field test was carried out to test the working performance of the hydraulic system of the whole machine.The test results showed that the average speed deviations of the hydraulic motors driving the first-stage lifting chain,the vibrating wheel,the second-stage lifting chain and the lifting device were 1.15%,2.05%,5.10%and 4.09%,respectively.The average retraction synchronization deviation rates of lifting,inclination adjustment and dumping hydraulic cylinders were 0.63%,1.16%and 0.62%,respectively,and the average retraction locking deviation rates were 0.34%,0.66%and 0.33%,respectively.The average extension synchronization deviation rate and the average extension locking deviation rate of dumping hydraulic cylinder were 0.56%and 0.30%,respectively.The results indicate that the designed hydraulic system can meet the operation requirements of self-propelled Panax notoginseng combine harvester,which can provide theoretical basis and reference for the design of the hydraulic system of rhizome combine harvesters in hilly and mountainous areas.
