PROBLEM TO BE SOLVED: To address such a problem in which, when removing relatively large misplaced materials such as waste straws from objects to be processed by a sheave, the misplaced materials such as the waste straws are entangled in a sorting net and attached thereto and inhibit fall of the misplaced materials to the lower-side sheave to lower sorting efficiency and accuracy.SOLUTION: The combine harvester includes: a swinging selection rack 25 for sorting kernels in processing objects, on a lower side of a threshing chamber 15 including a threshing cylinder 20 journaled thereto a primary conveyor 35 for collecting primary products out of the processing objects fallen from the swinging selection rack 25, on the lower side of the swinging selection rack 25 a sheave 27 for sorting the kernels and waste straws in the processing objects at a site on an upper side of the first conveyer 35 in the swinging selection rack 25 and a sorting net 40 for receiving fallen objects fallen from the threshing chamber 15, on an upper side of the sheave 27 at a prescribed interval T apart from the sheave 27 in the vertical direction.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2018,JPO&INPIT【課題】シーブが処理する被処理物の中から比較的大きい藁屑等の夾雑物を除去する場合、選別網に藁屑等の夾雑物が絡まって付着し、下方のシーブへの被処理物の落下を阻害し、選別効率および精度が低下するという課題がある。【解決手段】扱胴20を軸装した扱室15の下側に、被処理物中の穀粒を選別する揺動選別棚25を設け、該揺動選別棚25の下側に、該揺動選別棚25から落下した被処理物のうちの一番物を回収する一番コンベア35を設け、前記揺動選別棚25における、前記一番コンベア35の上方の部位に被処理物中の穀粒と藁屑とを選別するシーブ27を設け、該シーブ27の上方に該シーブ27と上下に所定間隔Tをあけて前記扱室15からの落下物を受け止める選別網40を設けたコンバイン。【選択図】図2
