The seed motion characteristics were investigated using DEM-CFD coupling approach. Airflow field of seed feeding device was simulated. The optimum structure of seed feeding device was obtained through gas-solid flow simulation. The proper airflow inlet velocity was achieved through comparison seed motion behavior in seed feeding device.
