PROBLEM TO BE SOLVED: To solve a problem that fixing operation of a discharge cylinder is troublesome conventionally due to such configuration that an intermediate part of a rubber band is placed on an upper face of the discharge cylinder and both ends are fitted on right/left both sides of a lower part of the discharge cylinder.SOLUTION: A threshing device 5 and a grain tank 7 are arranged on one side and the other side of an upper part of a travel device 3 respectively. A blowing cylinder 61 communicates with a bottom part of the grain tank 7 storing grains threshed by the threshing device 5. An inlet side of a first conveyance cylinder 20 is connected with an outlet side of the blowing cylinder 61, an inlet side of a second conveyance cylinder 30 is connected with an outlet side of the first conveyance cylinder 20, and thereby a discharge cylinder 10 is configured. The second conveyance cylinder 30 is configured to extend/contract in a length direction by means of an extending/contracting drive device 40. A discharge cylinder receiver 11 placing the discharge cylinder 10 thereon is configured at a predetermined position on a machine body by a receiver 14 including right/left arms 12 and having a U-shape in a front face view and a support rod 15 attached in a lower part of the receiver 14. A rubber band 16 is arranged in the discharge cylinder receiver 11, the rubber band wound over a casing 44 of the discharge cylinder 10 and the receiver 14 to be fixed.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2017,JPO&INPIT【課題】従来、ゴムバンドの中間部を排出筒の上面に当てがって両端を排出筒の下方の左右両側に係止する構成のため、排出筒の固定操作が面倒であるという課題がある。【解決手段】走行装置3の上方一側に脱穀装置5を、上方他側にグレンタンク7を夫々設け、脱穀装置5により脱穀した穀粒を貯留するグレンタンク7の底部に送風筒61を連通し、前記送風筒61の出口側に第1搬送筒20の入口側を接続し、該第1搬送筒20の出口側に第2搬送筒30の入口側を接続して排出筒10を構成し、前記第2搬送筒30は伸縮駆動装置40によって長さ方向に伸縮自在に構成し、機体上の所定部位には、排出筒10を載置する排出筒受け11を、左右の腕部12を有した正面視U字形状の受部14と該受部14の下部に取付けた支持杆15により構成し、前記排出筒受け11には排出筒10のケーシング44と前記受部14とを取り巻いて固定するゴムバンド16を設けたコンバイン。【選択図】図1
