| Abstract: |
| In order to determine the cutting speed ratio, press roller circumferential speed and reel speed ratio of mountain mower conditioner three key design parameters, an experiment was conducted in the right of requirements for pasture harvesting technology, with the low working stubble height, few recutting times, high flattening ratio and small broken grass loss rate as evaluating indicators. Through the orthogonal experiments, application comprehensive balance method to obtain the optimal combination working parameters: the cutting ration was 2.5, the press roller circumferential speed was 4.2 m·s-1, the reel speed ratio was 2.5. Measured with the optimal combination of o
perational parameters, the results showed that, the working stubble was 42 mm, the recutting rate was 0.73%, the flattening ratio was 46.5% and the crushed grass loss rate was 2.3%, which could meet the demand of forage harvest operation. |
