PROBLEM TO BE SOLVED: To solve a problem of a conventional discharge device that a discharge position of an unloader in a longitudinal direction cannot be adjusted, discharge work efficiency is low, and an unloader excessively lifted causes decrease in air velocity near an outlet of the unloader to result in jamming occurrence.SOLUTION: The combine includes: a threshing device 3 on an upper one side of a traveling device 2 and a grain tank 5 on an upper other side. A feed-out feeder 10 of the grain tank 5 storing grains threshed by the threshing device 3 is connected with an intermediate part of a discharge cylinder member 12 connected with a blower 13 on one end. The other end of the discharge cylinder member 12 is attached with: an unloader 17 vertically rotatable and expandable/contractable with respect to a vertical support cylinder 16 arranged on a machine body frame 1 and an expansion length detection part 35 detecting an expansion length of the unloader 17 for restriction control of expansion equal to or larger than a predetermined length of the unloader 17.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2016,JPO&INPIT【課題】従来の排出装置では、アンローダの長手方向の排出位置を調節できず、排出作業能率が低く、また、アンローダを過剰に上昇させると、アンローダ出口付近での風速が低下し、詰まり発生の原因となる課題がある。【解決手段】走行装置2の上方一側に脱穀装置3を、上方他側にグレンタンク5を夫々設け、脱穀装置3により脱穀した穀粒を貯留するグレンタンク5の繰出フィーダ10に、一端に送風機13を接続した排出用筒部材12の中間部を接続し、排出用筒部材12の他端には、機体フレーム1に設けた縦支持筒16に対して上下回動および伸縮自在のアンローダ17を取付け、アンローダ17の伸縮長さを検出する伸縮長検出部35を設け、アンローダ17の一定以上の伸長を規制制御するコンバイン。【選択図】図2
