中文摘要:为了解决燕麦清选装置清选性能低的问题,根据燕麦的物理特性对单风机三圆筒筛清选装置进行了结构改进,设计了一种燕麦弧形栅格筛复清选式圆筒筛清选装置。在大圆筒筛上安装了能使物料跳起、充分分离的跳跃板结构,并且设计和加装了弧形栅格式挡板筛及复清选部件,对大圆筒筛的跳跃板及弧形栅格式挡板筛的清选原理及受力进行了理论分析。以离心风机转速、大圆筒筛转速、弧形栅格式挡板筛倾角为试验因素,燕麦籽粒含杂率和损失率为试验指标,进行了室内三元二次正交旋转组合试验。室内试验结果表明:当离心风机转速为1500r/min、大圆筒筛转速为110r/min、弧形栅格式挡板筛倾角为41°时,本装置清选效果最好,含杂率为1.96%,损失率为2.64%。田间验证试验结果表明,在最优参数下,含杂率为1.97%,损失率为2.68%。

Abstract:In order to reduce the problem of low cleaning performance of oats cleaning device, the structure of single fan three cylinder screen cleaning device was improved according to the physical characteristics of oats, and a cylinder screen oats cleaning device with arc grid screen re-cleaning was designed. A skip plate structure was installed on the large cylinder screen, which can make the material jump up and fully separate. The arc grid baffle screen and re-cleaning parts was designed and installed to reduce the impurity content and the entrainment loss. Based on the performance parameters of traditional single fan three cylinder screen cleaning device, the cleaning principle and function of skip plate of large cylinder screen and arc grid baffle screen was analyzed theoretically. Taking the rotating speed of centrifugal fan, the rotating speed of large cylinder screen and the angle of arc grid baffle screen as the experimental factors, and the impurity content and loss rate of oat grain as the experimental indexes, the indoor ternary quadratic orthogonal rotation combined test was carried out. The results showed that when the rotating speed of centrifugal fan was 1500r/min, the rotating speed of large cylinder screen was 110r/min, and the angle of the arc grid baffle screen was 41°, the cleaning effect of the device was the best, the impurity content rate was 1.96%, and the loss rate was 2.64%. A field test was carried out. Under the optimum parameters, the impurity content rate was 1.97%, and the loss rate was 2.68%, which provided a reference for the optimization of the structure of the oat cleaning device and the improvement of the whole structure of oat combine harvester.

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.
