Influence of elliptical sieve movements on the functioning of the combine cleaning unit

Abstract: To increase the throughput of the cleaning unit in a combine harvester, an improvement of the separation process and thus an optimization of the mechanic and aerodynamic excitations is necessary. One opportunity to improve the functioning of the cleaning unit is to optimize the sieve movement. For this purpose, the cleaning unit test rig of the Institute of Agricultural Engineering was extended with a drive system that enables the investigation of linear, circular and elliptical sieve movements. The evaluation of the conducted investigations allows an assessment of the functioning of the cleaning unit. Parallel conducted Discrete-Element-simulations in combination with Computational-Fluid-Dynamics-simulations (DEM-CFD-simulations) allow the investigation of the particle movement of grain and material other than grain (MOG) and therefore a more detailed analysis of the processes. https://www.landtechnik-online.eu/landtechnik/article/view/47
