摘　　要：目的:验证针对平房仓仓底余粮而设计的清扫装置的传送部分和收集部分结构设计是否合理,并确定装置运行的关键参数,避免造成采购和制造方面的浪费。方法:基于离散元法采用EDEM仿真软件,对传送部分和收集部分的运行效果进行仿真,以洒落率为评价参数。结果:在保证传送部分和收集部分都能满足设计要求的情况下,波纹挡边带的最佳运行速度应控制在0.6~0.8 m/s。结论:该余粮清扫装置传送部分和收集部分的结构符合设计要求。Objective:To verify whether the structure design of the conveying part and the collecting part of the cleaning device designed for the surplus grain at the bottom of the cottage warehouse is reasonable,and to determine the key parameters of the device operation,so as to avoid the waste of procurement and manufacturing.Methods:Based on discrete element method,EDEM simulation software was used to simulate the operation effect of the transfer part and the collection part,and the drop rate was used as the evaluation parameter.Results:Through the observation and analysis of the simulation results,it was concluded that the optimal running speed of the corrugated flange belt should be controlled between 0.6 m/s and 0.8 m/s under the condition that the transmission and collection parts could meet the design requirements.Conclusion:The simulation study verifies that the structure of the transfer part and the collection part of the surplus grain cleaning device meets the design requirements,and can provide a reference for the design of the equipment for the transfer and collection of grain materials.
