| 摘 要： | 针对夹持式棉花精密穴播轮作业引起的振动脱种问题，改进了取种器的结构，增设了护种装置。应用二次回归通用旋转组合试验方法，建立了穴播轮排种性能指标与取种器夹种口主要尺寸间的回归方程。分析了试验因素对穴播轮排种性能指标的影响规律，对于新陆早-26号棉种在单粒率最大、重播率和空穴率在一定范围内的条件下，优化得出夹种板长度为4.50mm、夹种口宽度为5.70mm、夹种口开度为7.50mm。试验表明，改进后的穴播轮减小了振动对精密取种的影响。 |

| Abstract: | Aiming at the seed-dropping problems of clamping cotton-seeds precision dibbler due to vibration in operating,the seeding devices of the dibbler were improved.A seed retaining equipment was designed and installed on the dibbler.Mathematical models that described relationship between the performance indexes and influence factors of the seeding devices were established by applying quadrate regression experiment with general rotary design method.The tendency and regularity of the performance indexes influenced... |
