In this paper, based on the problem of poor operation of sweet potato harvester, the discrete element method and TRIZ theory are used to optimize the key mechanism. Based on the discrete element method, EDEM software was used to simulate the operation process of the potato soil conveying and separating mechanism, and the optimal combination of working parameters was obtained. The linear velocity of the rod lift was 2.3 m/s, the inclination angle was 18 degrees, and the amplitude was 8 mm. Field experiments were carried out to verify the results. Through the problems in simulation and field experiment, based on TRIZ theory, the improvement scheme is proposed by using physical contradiction, and the two-stage potato soil transport separation mechanism is obtained. The simulation results show that the operation effect is improved obviously. Finally, the optimization of potato soil transport and separation mechanism is completed by determining the optimal working parameters and improving the structure innovation.
