中文摘要:分析了玉米根茬破碎还田装置中直刀、旋耕刀、月牙刀的破茬原理,试验验证了月牙刀滑切破茬具有土壤扰动小、功耗低、破碎能力强的特点。以刀辊转速、机器前进速度、切刀入土深度为试验因素,以功耗、破茬合格率为试验指标,分别建立了表征月牙刀破茬性能的数学模型,确定最佳参数为:切刀入土深度48 mm,机器前进速度0.77 m/s,刀辊转速266 r/min。在试验范围内,切刀入土深度对功耗的影响最大;刀辊转速和机器前进速度对破茬合格率影响最大。

Abstract: This paper analyzed the smashing theory of straight blades, crescent blades and bent blades respectively. With the velocity of roller, the machine speed and the depth in the dust as the test factors, and the percent of pass and the power consumption as the test indexes, the experiments were carried out subsequently. The advantages of crescent blades, such as small disturbance, low power consumption and high pass percent were validated by experiment. Finally, the regressive mathematic model of crescent blades smashing performance was established and the optimum parameters were obtained by regressive analysis.  

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.
