| Abstract: |
| In order to examine and optimize the working performances of independently developed 1MLQS-40/70 combined machine with ridge forming and paving plastic mulch, taken the degree of mechanical damage on lighting surface，the qualified rate of soil covered width at film side, the qualified rate of soil covered thickness at film side and the degree of miss covered soil on film for the operation index, adopted the orthogonal test as three-factors and three-levels. Through the range and variance analysis, has obtained the significant effect of longitudinal space beween soil elevator front axle and the furrowing shovel installation axle. Through the comprehensive balance method to carry out the optimal analysis for the experimental data, has obtained the maximal parameter combination as: The longitudinal space between soil elevator front axle and the furrowing shovel installation axle was 30 mm，the ratio of soil lifting elevator speed and working speed of the machine was 2.5, the angle of furrowing shovel was 25°. The validation test showed that degree of mechanical damage on lighting surface was less than1%, the qualified rate of soil covered width at film side was more than 95%, the qualified rate of soil covered thickness at film side was more than 95% and the degree of miss covered soil on film was less than 1%. |
