半喂入联合收割机指作物仅穗头进入脱粒滚筒脱粒而茎秆留在机外的联合收割机。其特点是有较长的夹持输送链和夹持脱粒链,脱粒时,只将作物穗部送入滚筒,因而保持了茎秆的完整性,因为茎秆不进入滚筒,机器上的分离装置可大大简化或省去,耗用的功率也大为减少,采用的都是弓齿轴流式滚筒,在收获水稻方面具有显著的优势。为保证脱净,半喂入联合收割机夹持脱粒的茎秆层不能太厚。
Semi-fed combine harvester refers to the crop only spit head threshing barrel threshing and stalks stay outside the combine harvester. It is characterized by a long holding conveyor chain and holding the threshing chain, threshing, only the crop spike into the drum, thus maintaining the integrity of the stem, because the stem does not enter the drum, the separation device on the machine Can be greatly simplified or omitted, the power consumption is also greatly reduced, using bow-axis axial drum, rice has a significant advantage in the harvest. In order to ensure the net, semi-fed combine harvester threshing stalk layer can not be too thick.
