目前国内外研制和生产的半喂入联合收割机基本上都装有副滚筒,主要是处理来自主滚筒的断穗,以及进一步从杂余中将籽粒分离出来。在收获麦类作物时,由于茎秆较脆,茎秆与穗的连接力小,很容易产生断穗,因此加装副滚筒进行复脱处理尤为必要。现半喂入联合收割机采用的副滚筒型 At present, semi-feed combine harvesters developed and manufactured at home and abroad are basically equipped with auxiliary rollers, mainly for processing the cuttings from the main drum and for further separating the grains from the impurities. When harvested wheat crops, stems more brittle, stems and spike connection is small, it is easy to produce cuttings, so the installation of secondary roller complex removal treatment is particularly necessary. Now half-fed combine harvester used deputy roller type
