中文摘要:为了解决小型联合收获机清选装置谷糠分离不彻底和损失率较高的问题,利用高速摄影装置研究了吸杂风机转速、扬谷器风机转速和通气孔直径对清选性能的影响机理,以小麦籽粒、颖糠、茎秆混合物料为对象,利用研制的旋风分离系统试验台,选取气孔排布方式、通气孔直径、吸杂风机转速和扬谷器风机转速为试验因素,清洁率和损失率为试验指标,进行了单因素和多因素清选性能试验。单因素试验结果表明,气孔排布方式为螺旋形时,清选效果较好,随着吸杂风机转速、扬谷器风机转速和通气孔直径的增加,清洁率先上升后降低,损失率则逐渐增加,最大损失率不超过2%;正交试验表明:吸杂风机转速为1900r/min、扬谷器风机转速为1100r/min、通气孔直径为8mm时,清洁率平均值大于93%,损失率平均值低于1.5%,损失率比优化前降低了25%。

Abstract:In order to solve the problems of halfway separating and high losing rate of the cyclone separation system, material movement analysis was done by using of high speed photography. The wheat and mixture of stalk were chosen as the experiment objects, statistical experiment was carried out when diameter of air pores, rotating speed of the fan and rotating speed of the winnower were chosen as the experiment factors and cleaning rate and losing rate were chosen as the experiment indicators. Single factor experiment result showed that the arrangement of the air pores had effect on the cleaning ability. When the arrangement of the pores was spiral, the system performed better. The cleaning rate was increased first and went down later with the increasing of the rotating speed of the fan, winnower and the diameter of the air pores. The losing rate was increased with the increasing of the rotating speed of the fan, winnower and the diameter of the air pores, the value of losing rate was no more than 2%. Multi factor experiment result showed that when the rotating speed of the fan was 1900r/min, the rotating speed of the winnower was 1100r/min and the diameter of the air pores was 8mm, the cleaning system worked better, the average value of losing rate was less than 1.5%, which was reduced by 25% compared with the former.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
