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.
