| 摘要: |
| 针对我国大蒜主产区种植特点研制的4DLB-2型半喂入自走式大蒜联合收获机,在国内同类机型中技术水平较为先进。为进一步掌握该机性能,在已有试验基础上对该机的田间收获性能进行测试,测试不同作业速度、种植模式下的生产率、损失率、含土率、伤蒜率、留梗长度等主要技术指标,考核该机的田间作业效果,并对测试数据进行了分析。结果表明:该机生产率为0.13~0.21 hm2/h,大蒜损失率1.1%~2.3%,含土率1.3%~1.5%,伤蒜率1.7%~2.2%,蒜头留梗长度31.9~43.6 mm,各项性能指标均达到设计要求。 |

| Abstract: |
| 4DLB-2 half-feed and self-propelled garlic combine harvester was developed according to the garlic cultivation characteristics of garlic main production area in China.The field test was taken for the performance verification.The machine' key performance indicators were tested in different operating speeds and cropping patterns including productivity,garlic loss rate,soil-content rate,garlic injury rate,garlic obvious rate,etc.The test analysis showed the productivity was 0.13-0.21 hm2/h,garlic loss rate was 1.1%-2.3%,soil content rate was 1.3%-1.5%,garlic injury rate was 1.7%-2.2%,and garlic stalk staying length was 31.9-43.6 mm.The data stated the combine harvester had reached the design requirements. |
