PROBLEM TO BE SOLVED: To provide a combine-harvester capable of softly changing the ratio, at which a re-selection is performed according to the kind of a crop or a harvest target.SOLUTION: A combine-harvester comprises: a threshing part for threshing the crop and a selecting part 24 for performing a selection treatment while transferring a processed product to be threshed. The selecting part 24 includes a first selecting part 61 for selecting the processed product coarsely, and a second selecting part 54 positioned below the first selecting part 61 for selecting the processed product finely. Further comprised are: a first recovery part 50 positioned below the second selecting part 54 for recovering to store the product selected a second recovery part 51 positioned on the downstream side of the first recovery part 50 in the transportation direction of the selecting part, for re-selecting the product to be selected a guide part 58 positioned below the second selecting part 54 and formed in a shape inclined down forward, for flowing down and guiding the selected processed part having passed through the second selecting part 54 toward the first recovery part 50 and an adjustment mechanism 100 capable of adjusting the size of a clearance S between the transportation terminal end of the second selecting part 54 and the rear upper end part of the guide part 58.SELECTED DRAWING: Figure 5COPYRIGHT: (C)2017,JPO&INPIT【課題】収穫対象となる作物の種類に応じて再選別を行う割合を柔軟に変更できるコンバインを提供する。【解決手段】作物を脱穀処理する脱穀部と、脱穀処理物を搬送しながら選別処理する選別部24と、が備えられ、選別部24に、脱穀処理物を粗選別する第一選別部61と、第一選別部61の下方に位置し、脱穀処理物を精選別する第二選別部54と、が備えられ、第二選別部54の下方に位置し、選別処理物を貯留のために回収する第一回収部50と、選別部の搬送方向において第一回収部50よりも下手側に位置し、選別処理物を再選別のために回収する第二回収部51と、第二選別部54の下方に位置するとともに前下がりの傾斜形状に形成され、第二選別部54を通過した選別処理物を第一回収部50に向けて流下案内するガイド部58と、第二選別部54の搬送終端部とガイド部58の後上端部との間の隙間Sの大きさを調整可能な調整機構100と、が備えられている。【選択図】図5
