Abstract

Airflow field play an important role on the cleaning performance of the air-and-screen cleaning device of the plot harvester, and an unreasonable airflow field can lead to poor cleaning quality. In order to understand the cleaning chamber airflow distribution and improve the cleaning quality of the cleaning device, the orthogonal experiment method is used for the numerical simulation on the plot harvester. The workbench is utilized to extract geometric model flow and mesh division on condition that the original shape and size of the fisheye sieve are kept. By means of CFD software FLUENT, the plot harvester airflow field is simulated and analyzed by changing the cross flow fan angle, the clear inclination of sieve and the cross flow fan speed . Test results show that the effective separation parameter is: the cross flow fan speed is 12m/s, the cross flow fan angle is 20°, and cleaning sieve angle is 6°.
