中文摘要:以螺旋叶片、板齿组合式轴流脱粒与分离装置为研究对象,借助高速摄像技术对稻谷的脱粒过程和脱粒后籽粒的运动方式进行了观察,通过观察分析可知,籽粒在脱粒部件梳刷、冲击 、碰撞及物料之间相互搓擦的作用下,从枝梗上分离下来,期间稻穗呈环扣状,籽粒以环扣为中心向四周散射。稻谷进入脱粒空间后迅速形成薄层,并在脱粒部件和导向叶片的联合作用下,旋转向前涌动。当稻谷层受到冲击和梳刷作用时,瞬间被压缩,随之被抛离,呈蓬松状态,使被脱下的籽粒有机会穿过蓬松茎秆层分离出去。

Abstract:

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.
