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.
