| Abstract: | By further studying the basic physical characteristics of grain seeds,the relation between path and stress of grain seeds in horizontal airflow was analyzed.After the boxed-pneumatic cleaning mechanism had been designed,the conservation equations of the cleaning flow field were determined.By means of Fluent software,the gas-solid multiphase flow eulerian model was established,and the cleaning course was simulated.In virtue of the analytic data acquired,the possibility of the pneumatic cleaning mechanism used for mini-combine harvester was demonstrated. |
