摘　　要：针对甘薯两段式联合收获机作业过程中二级输送分离装置伤薯严重、土薯分离效果差等问题,设计了一种高低间隔式二级输送分离装置。通过结构参数及运动学分析,得出了影响二级输送分离装置作业效果的关键因素,同时确定了各影响因素的取值范围。基于二次正交旋转组合试验,得出了试验指标最佳的因素取值。田间收获试验表明:线速度为0.6 m/s、振动幅度为26.2 mm、振动频率为6.6 Hz时,伤薯率为0.797%、去土率为74.839%。研究结果可为甘薯两段式联合收获机的结构参数优化提供参考。For sweet potato two-stage combine harvester operation,the secondary conveyor separator device injures potato seriously,and the effect of soil and sweet potato separation is poor.A high and low interval secondary conveyor separator device was designed.By means of structural parameters and kinematic analysis,the key factors of the operational effect of the secondary conveyor separator were derived.At the same time,the value range of each influencing factor was determined.Based on a quadratic orthogonal rotation combination test,the value of the best factors for the test index was drawn.The field harvest test shows that the potato injury rate is 0.797%,and the soil removal rate is 74.839%,in the case of the speed of high and low interval secondary conveyor separator device is 0.6 m/s,the vibration amplitude is 26.2 mm,and the vibration frequency is 6.6 Hz.The results of the study can provide a reference for the structure improvement and operation parameters optimization of the two-stage sweet potato combine harvester.
