摘要 为设计便携式谷物联合收获机清选系统,利用双扬谷器旋风分离清选系统试验台,在无物料状态下通过研究两级扬谷器之间和二级扬谷器与风机之间输送管道内气流状态,确定了物料顺利输送的一、二级扬谷器和风机转速的选取范围,物料试验以小麦为试验对象,以一级扬谷器、二级扬谷器和吸杂风机转速作为试验因素,以清洁率为试验指标,进行了正交试验和回归试验,优化确定了最佳参数值。当一级扬谷器、二级扬谷器、风机转速分别为300、764、3255r/min时,籽粒清洁率达99%以上。 To solve the cleaning problems of portable reaper, the cleaning system test bench was designed and the wheat was chosen as the experimental object. Air flow test without material was done and analyzed the static pressure in the two stages of pipelines. The relation among the speed of first and second level winnower and the fan can be found. The test can provide the selection scope of motion parameters for the material test. In material test, the fan speed and the first and second winnower speed were selected for test factors, and the cleaning rate for test indicator. Through orthogonal test and quadratic general rotation test, the motion parameters of wheat were found out when its cleaning rate was best and the impact of individual factor on the indicator was researched by regression equation. The best motion parameters can be found through the test: when the speed of first and second level winnower and the fan was 300 r/min,764 r/min,3 255 r/min , the cleaning rate would be best. This combination of parameters will apply to portable reaper cleaning systems, and provide the system the reliable movement parameters.
