| Research Abstract |
For improving cleaning efficiency of combines, the grain flow model was devised, and the return rates from 2ndauger and grain losses were measured by experiments. As a result, the return rates were converged to the steady value with increasing flow on the cleaning shoe, and the rates of grain losses were decreased. On the other hand, in order to clarify the behavior of grains on the cleaning shoe, the DEM model by coupling spheres were devised, and it was verified by repose angles. Taking these results,it was obtained that 7 particles coupling element was appropriate.
