PROBLEM TO BE SOLVED: To provide a combine which forcibly discharges grains remaining in a grain tank and which has high grain collection performance.SOLUTION: A grain tank 6 is formed by a tank part 60 located in an upper part and having a shape of a general rectangular parallel-pipe and a funnel part 61 located in a lower part and having a shape of a general inverted rectangular pyramid. A lifting-grain device 55 transferring grains from a lower part of a threshing device 4 to a feed port 60E of the tank part 60 is arranged. Right/left front nozzles 63A, 63B injecting pressure-fed air toward right/left front connection parts 62A, 62B are arranged on an upper side of the right/left connection parts 62A, 62B of a front wall 61A of the funnel part 61 and right/left walls 61C, 61D arranged in the right/left of the front wall 61A. Right/left rear nozzles 63C, 63D injecting pressure-fed air toward right/left rear connection parts 62C, 62D are arranged on an upper side of the right/left rear connection parts 62C, 62D of a rear wall 61B of the funnel part 61 and right/left walls 61C, 61D arranged in the right/left of the rear wall 61B. Thereby, the problem is solved.SELECTED DRAWING: Figure 13COPYRIGHT: (C)2017,JPO&INPIT【課題】グレンタンクに滞留する穀粒を強制的に排出して、穀粒の回収能力が高いコンバインを提供する。【解決手段】グレンタンク(6)を、上部の略長方体形状のタンク部(60)と下部の略逆四角錐形状の漏斗部(61)で形成し、脱穀装置(4)の下部からタンク部(60)の供給口(60E)へ穀粒を移送する揚穀装置(55)を設け、漏斗部(61)の前壁(61A)と前壁(61A)の左右に設けられた左右壁(61C,61D)の左右前連結部(62A,62B)の上側に、左右前連結部(62A,62B)に向けて圧送空気を噴射する左右前ノズル(63A,63B)を設け、漏斗部(61)の後壁(61B)と後壁(61B)の左右に設けられた左右壁(61C,61D)の左右後連結部(62C,62D)の上側に、左右後連結部(62C,62D)に向けて圧送空気を噴射する左右後ノズル(63C,63D)を設けることにより解決される。【選択図】図13
