Abstract

RockyDEM is used to simulate the conveying and soil-removing device to determine its optimal structural parameters in order to solve the problem of low soil removal rate and high straw loss rate of the conveying and soil-removing device of the corn straw picking and pelletizing machinery.Single-factor and multi-factor simulation tests were conducted with soil removal rate and straw loss rate as evaluation indexes, and blade to shell clearance, sieve aperture and pitch as influencing factors.The results from the experimental the soil removal rate and the straw loss rate and simulation data from the model showed good agreement. Therefore, the procedures of this study can be used for the design and optimisation of conveying and soil-removing device.

为解决玉米秸秆捡拾造粒机械的输送除土装置除土率低、秸秆损失率高的问题,采用RockyDEM对输送除土装置进行模拟,确定其最佳结构参数。 以土壤去除率和秸秆损失率为评价指标,以叶片与壳体的间隙、筛孔和间距为影响因素,进行了单因素和多因素的模拟试验,土壤去除率和秸秆损失率的试验结果与模型的模拟数据显示出良好的一致性。因此,本研究的程序可用于输送和除土装置的设计和优化。
