摘  要：
起膜作业是残膜回收的重要环节,针对现有残膜回收机起膜装置存在可靠性低、起膜率低的问题,设计了一种滑刀式起膜装置。通过对起膜铲起膜机理进行分析,确定了导曲面参数方程和主要结构参数。以起膜铲间距、机具作业速度、入土角为试验因素,以起膜率为响应值,利用Design-Expert 8.0.2软件进行回归分析和响应面分析,得出各因素对起膜率的影响由大到小为:入土角、起膜铲间距、机具作业速度;建立了起膜率与入土角、起膜铲间距和机具作业速度的三元二次回归模型。采用非线性优化计算方法,对起膜铲的结构参数和工作参数进行优化计算。结果表明:当起膜铲间距为220 mm,作业速度为1.0 m/s,入土角为30°时,起膜率理论最大值为93.8%,验证试验表明该参数下的起膜率为91.3%,理论值与试验值误差为2.5%,验证了回归模型的正确性。

摘  要：
Plastic film cultivation technology,which was hailed as "the second revolution of agricultural production",had the effects of increasing temperature,conserving soil moisture,suppressing weed and boosting crop yield. However,the major ingredients of agricultural plastic mulching film are polyolefin compounds which are degradation-resistant. The mechanization of residual film recycling is an effective approach for solving pollution of residual films. The major operation procedures of residual film recycling include releasing film,collecting film and removing film,and unloading and releasing film operations are the crucial link of recycling residual films. Concerning existing releasing equipment of residual film collector had the problem of low reliability and film releasing rate,a runner-type film releasing equipment was designed. Through analysis on the film releasing mechanism of this equipment, its structural characteristics and dimension parameter were determined. Taking the space between film releasing shovels,forward speed and penetrating angle as influence factors and film releasing rate as response value,the influence of each factors on film releasing rate was calculated based on the regression analysis and response surface analysis with Design-Expert 8. 0. 2 software. The contribution of each factor to the influence on film releasing rate from big to small were penetrating angle,space between film releasing shovels and forward speed. Three-factor quadratic regression models between film releasing rate andpenetrating angle of film releasing shovels,forward speed and space between film releasing shovels were established. Optimizing calculation of structure and working parameters of film releasing shovels was conducted through calculation method of nonlinear optimization. The results showed that when the space between film releasing shovels was 220 mm,forward speed was 1. 0 m / s and penetrating angle was 30°,the theoretical maximal film releasing was 93. 8%. Proof test indicated that the film releasing rate with these parameters was 91. 3% and the error between theoretical value and trial value was 2. 5%,which verified the correctness of regression model.
