PROBLEM TO BE SOLVED: To arrange an auxiliary fuel tank of a large capacity by utilizing a space in the periphery of a vertical auger, so that a work interruption for oil supply during operation may be reduced to enhance the efficiency of a harvesting work.SOLUTION: A fuel tank (15) is disposed at a portion of a left side of the right wall (9A) of a discharge straw processor(9) at a rear portion of an airframe frame (1). At a portion of the right side of the right wall (9A) of a discharge straw processor (9) in the rear portion of the airframe frame (1), there is disposed an auxiliary fuel tank (100) having a second oil supply port (22) for supplying a fuel from a fuel container. A first oil supply port(16) disposed in the right side face of the fuel tank (15) and an oil discharge port (24) disposed in the proximal of the auxiliary fuel tank (100) are made to communicate, and the auxiliary fuel tank (100) is disposed along a vertical auger (8A).SELECTED DRAWING: Figure 19COPYRIGHT: (C)2018,JPO&INPIT【課題】縦オーガの周辺の空間を利用して、容積の大きな補助燃料タンクを配置し、作業中における給油のための作業中断を少なくし、収穫作業の能率を高める。【解決手段】機体フレーム(1)の後部における排藁処理装置(9)の右壁(9A)よりも左側の部位に燃料タンク(15)を設け、機体フレーム(1)の後部における排藁処理装置(9)の右壁(9A)よりも右側の部位には、燃料容器から燃料を給油する第2給油口(22)を有した補助燃料タンク(100)を設け、燃料タンク(15)の右側面に有した第1給油口(16)と補助燃料タンク(100)の基部に有した排油口(24)を連通し、補助燃料タンク(100)を縦オーガ(8A)に沿わせて設ける。【選択図】 図19
