摘要
梳穗收获是将谷粒直接从田间站立的作物上梳脱下来。田间和室内试验测定结果表明:籽粒和穗头占梳脱混合物的76.7%和73.9%,断穗和籽粒在长秆和短秆中的含量为3.0%和4.6%。梳穗收获使进入复脱滚筒的非谷物量减少,功率消耗大大降低。为此,对梳穗收获机的预分离装置、复脱滚筒进行了设计和试验,简化了收获机的结构,简化了脱粒后谷粒的破碎率。
Stripper harvesting is to strip grains directly from crops in the field. Field and indoor experiments show that seeds and short lever account for 76.70% and 73.90% of the picked respectively while broken fringes and seeds account for 3.00% and 4.60% of a long lever. Stripper harvesting can reduce the quantity of non-grain materials in the re-threshing roller and greatly cut down consumption of energy. This paper describes the devising and testing of pre-separating and re-threshing device, aiming at simplifying the structure of the harvesting stripper and decreasing the rate of seeds being smashed during threshing.
