PROBLEM TO BE SOLVED: To provide a combine harvester efficiently performing harvesting operations, taking out grains from a grain tank, and facilitated in high-speed running.SOLUTION: A traveling machine body travels by itself with travelling wheels 1, 2. A threshing device 10 includes: a threshing chamber in which reaped culm is put from its cut portion to its ear tip and a threshing cylinder driven so as to rotate around the shaft core of the threshing cylinder in the longitudinal direction of the traveling machine body. The grain tank 20 is provided with: a side tank part 21 located at the side of the threshing device 10 and an upper tank part 22 located at the upper side of the threshing device 10. On the grain tank 20, a discharge screw 60 is installed while driven to rotate around the screw shaft core in the longitudinal direction of the traveling machine body, and a carrying-out auger 63 carrying out the grains from the discharge screw 60 is installed.COPYRIGHT: (C)2014,JPO&INPIT【課題】収穫作業を能率よく行うことができ、穀粒タンクからの穀粒取り出しを行ない易いコンバインを高速走行し易い状態で得る。【解決手段】走行機体は、走行車輪1,2で自走する。脱穀装置10は、刈取り穀稈を切断箇所から穂先まで投入する扱室、走行機体前後向きの扱胴軸芯まわりに回転駆動される扱胴を備えている。穀粒タンク20は、脱穀装置10に対して側方に位置する側方タンク部21と、脱穀装置10の上方に位置する上方タンク部22とを備えて構成してある。穀粒タンク20に排出スクリュー60を走行機体前後向きのスクリュー軸芯まわりに回転駆動される状態で設け、排出スクリュー60からの穀粒を搬出する搬出オーガ63を設けてある。【選択図】図1
