中文摘要:设计了谷物联合收获机脱粒滚筒液压无级变速系统,对该系统中封闭液压油的压力进行测量,用该油压力表示喂入量。通过台架试验,得出喂入量与油压力之间的关系方程,并与脱粒滚筒转速表示喂入量的方法进行了对比。结果表明:在联合收获机稳定工作,物料物理特性一致时,油压力随喂入量的增加呈线性上升,而此时脱粒滚筒转速可以视为常量,所以油压力能够准确地反映喂入量。

Abstract:Feed rate of combine harvester was affected by many factors and difficult to be detected directly. A hydraulic stepless transmission system of threshing cylinder was designed, and the oil pressure was monitored. The oil pressure was used to represent the feed rate. By the engine bench tests, the relation equation between feed rate and oil pressure was obtained, and the distinguished method of oil pressure and threshing cylinder rotate speed which indicated feed rate was compared. Experiment results showed that the oil pressure could indicate feed rate timely and accurately, oil pressure was linear with the feed rate when the combine harvester was in the stable operation and crop properties were in the same. The threshing cylinder rotate speed could be considered as a constant.

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.
