摘　　要：为了提高大豆调质塔下料器的工作效率和下料平稳性,结合离散元方法模拟大豆在下料器内的运动过程,分析转子叶片数量、淌料板角度、进出料口夹角对下料器工作效率和下料平稳性的影响。结果表明:当下料器转速为12 r/min时,转子叶片数量对下料器的工作效率和下料平稳性呈显著的负相关关系。淌料板角度对下料器的工作效率及平稳性影响不明显,但会导致物料在进料口处残留。进出料口夹角值越大,下料器的工作效率越低,但下料平稳性越好。研究表明,当转子叶片数量为6个,淌料板角度为40°,进-出料口夹角为180°时,下料器的工作效率及平稳性综合达到最优。To improve the work efficiency and stability of discharger in soybean conditioner,this paper combined the discrete element method to simulate the motion process of soybeans in the discharger,and analyzed the effects of rotor blade number,feeding plate angle,and angle between inlet and outlet of the discharger.The results showed that when the velocity of discharger was 12 r/min,the number of rotor blades had a significant negative correlation with the discharger's work efficiency and stability.The feeding plate angle had no significant on the work efficiency and stability,but it would cause material residue at the inlet of discharger.The larger the angle between the inlet and outlet led to the lower the work efficiency of discharger,but the work stability was better.The above research showed that when the number of the rotor blades was 6,the feeding plate angle was 40°.The angle between inlet and outlet was 180°,and the work efficiency and stability of discharger reached optimal levels.
