中文摘要:为准确获取纵轴流脱粒分离装置在水稻脱粒中的功耗特性,借助扭矩传感器、信号采集卡及工控机测控系统在纵轴流滚筒转速为850r/min、钉齿间距为100mm、脱粒间隙为25mm、草谷比为2.6、喂入量为7kg/s条件下,于室内台架上进行了水稻脱粒功耗测定试验。通过对水稻脱粒过程中功耗特性的分析,提取水稻脱粒的瞬间功耗,得知钉齿纵轴流滚筒的空载功耗为10.93kW、脱粒功耗为36.94kW、机械效率为69.62%。采用单因素试验对影响钉齿纵轴流滚筒总功耗及籽粒损失率(夹带损失率和未脱净损失率)的齿间距、脱离间隙、滚筒转速、草谷比及喂入量进行室内台架试验研究,分析了单个因素对钉齿纵轴流滚筒总功耗和籽粒损失率的影响情况。

Abstract:In order to accurately obtain power characteristics of longitudinal axial-threshing unit test-bed, rotary torque sensors, signal acquisition card and industrial computer control system were used to measure the power of rice threshing with the drum rotate speed of 850r/min, inter-tooth space of 100mm, threshing clearance of 25mm, straw-grain ratio of 2.6, feeding capacity of 7kg/s. Instantaneous power was obtained by analyzing the power of rice threshing process characteristics. The results showed that the idle power of spike tooth longitudinal axial-threshing drums was 10.93kW; the threshing power was 36.94kW; mechanical efficiency was 69.62%.The experiment of power influencing factors, such as feeding capacity, inter-tooth space, straw-grain ratio, drum rotate speed and threshing clearance, was conducted on the longitudinal axial-threshing unit test-bed to analysis the threshing power characteristics and threshing performance.

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.
