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 13 |
