中文摘要:针对现有残膜回收机起膜铲起膜率低、膜土分离难和工作可靠性低等问题,提出一种旋转式起膜装置,通过对该装置起膜过程中残膜和土壤混合物受力及运动分析,确定了膜土能够被抛离的条件以及残膜可被弹齿“接”住的条件。通过对起膜机理的分析,将起膜刀轴转速、起膜刀轴与输膜弹齿之间的水平距离、垂直距离作为试验因素,以起膜率、回收率和含土率作为评价指标,运用Design-Expert软件中的Box-Benhnken Design方法设计三因素三水平试验,分析各因素对作业质量的影响。试验结果表明,对起膜率影响顺序依次为:起膜刀轴转速、垂直距离、水平距离;对回收率影响顺序依次为:起膜刀轴转速、水平距离、垂直距离;对含土率影响顺序依次为:起膜刀轴转速、垂直距离、水平距离。利用Matlab 2016a软件中绘制上述3个因素的四维切片图,分析各因素对响应指标的综合影响效应。分析结果表明,起膜刀轴转速越高,起膜率越高,反之起膜率越低,而水平距离和垂直距离对起膜率影响比较小;起膜刀轴转速越高、水平距离越小、垂直距离越小,回收率越高,含土率越高,反之,回收率越低,含土率越低。对影响因素进行综合优化后得到最优的工作参数组合,起膜刀轴转速为680r/min,起膜刀轴与输膜弹齿之间水平距离为250mm,起膜刀轴与输膜弹齿之间垂直距离为320mm。对上述组合进行田间试验验证,起膜率为90.1%,回收率89.5%,含土率11.8%,结果表明该装置优化方案可行。

Abstract:A rotary film-lifting device was proposed in view of the problems of low filming rate, difficult separation of membrane soil and low work reliability. Through the force and movement analysis of membrane mixture in the membrane process of the device, the conditions for the membrane and soil to be thrown away and the conditions for the residual membrane to be “stucked” by the spring teeth were determined. Through the analysis of the mechanism of filming, the horizontal distance and vertical distance between the rotating speed of knife shaft, the knife cutting axis and film spring were taken as experimental factors, and the filming rate, recovery rate and soil fraction were taken as the response indicators. The three-factor and three-level tests were designed by using the Box-Benhnken Design method in Design-Expert software, and the influence of various factors on the quality of the work was analyzed. The test results showed that the descending order of influence of filming rate was filming-cutter shaft speed, vertical distance and horizontal distance;the descending order of recovery rate was filming-cutter shaft speed, horizontal distance and vertical distance;the descending order of soil rate was film cutter shaft speed, vertical distance and horizontal distance. The four-dimensional slice diagram of the above three factors was plotted in Matlab 2016a software to analyze the comprehensive effect of each factor on the response indicators. The analysis results showed that with the increase of rotating speed of the knife shaft, the filming rate was increased. The higher the rotating speed of the knife shaft was , the more the horizontal distance was. After comprehensive optimization of the influencing factors, the optimal working parameter combination was obtained. The speed of the film-cutting shaft was 680r/min, and the horizontal distance between the film-cutting shaft and the transporting elastic teeth was 250mm. The vertical distance between the teeth was 320mm. The above combination was tested in the field, the filming rate was 90.1%, the recovery rate was 89.5%, and the soil rate was 11.8%. The results showed that the optimization scheme of the device was feasible.

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.
