中文摘要:为了研究切流与纵轴流组合式脱粒分离装置的作业性能,在纵轴流脱粒分离清选试验台上,对钉齿滚筒、矩形齿滚筒和钉齿-短纹杆板齿组合式滚筒进行了台架试验,比较其夹带损失率、未脱净率、脱出物轴向分布规律、含杂率和功耗。试验结果表明,3种复脱滚筒在脱粒小麦时夹带损失率小,脱净率高;相对钉齿滚筒及矩形齿滚筒而言,钉齿-短纹杆板齿组合式滚筒脱出物轴向分布均匀,含杂率和功耗较低。

Abstract: In order to analyze the working performance of the rethreshing separation unit combined with a tangential-threshing and an axial threshing, including losing rate, distribution of the mixture along the axial of cylinder, the rate of impurity and power consumption, three threshing drums, i.e., the spike tooth, the rectangular tooth or the spike-short-rasp-bar tooth, were developed and test on the rig of the axial-threshing separation performance with axial feeding. The results show that three drums have low losing rate. Compared with the spike tooth and the rectangular tooth, the drum with spike tooth and short-rasp-bar tooth has uniformal distribution of the mixture along the axial of cylinder, less impurity contents and lower power consumption while threshing wheat.

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.
