| 摘要: |
| 针对现有的秸秆粉碎还田机工作幅宽小及作业质量不高的问题,研究开发了一种宽幅秸秆粉碎还田机,对影响秸秆切碎长度和留茬高度的各因素进行了正交试验。结果表明:机具前进速度对秸秆切碎长度影响极显著,甩刀轴转速和离地间隙对秸秆切碎长度影响显著;机具前进速度、甩刀轴转速和离地间隙对留茬高度影响都极显著,其中甩刀轴转速对留茬高度影响最大。鉴定试验结果表明:机具的作业速度为6.9 km/h,棉秆粉碎长度126.8 mm,残茬高度76.3 mm,主要技术指标达到了标准要求。 |

| Abstract: |
| According to the problems,such as small working width and unstable working quality,of the existing straw choppers,a new wide straw chopper was developed.The orthogonal test was designed for the evaluation of the factors that influence the chopped straw length and stubble height.The results showed that the machine forward speed,the flail knife shaft speed and ground clearance were very significant to the length of the straw chopped,and they were also very significant to the stubble height.Of the three flail knife shaft speed had the greatest impact on stubble height.Official evaluation testing indicated that the forward speed of the machines could be 6.9 km/h,cotton stalk crushing length was 126.8 mm and stubble height was 76.3 mm,which could meet the standard requirements. |
