PROBLEM TO BE SOLVED: To provide a combine which can easily discharge grains.SOLUTION: A combine 1 includes: a grain tank 7 arranged on a machine body frame 2 and storing grains a first conveyance cylinder 20 arranged on a rear side of the machine body frame 2 and having one end part connected with the grain tank 7 a second conveyance cylinder 30 arranged on an upper part of the machine body frame 2, having one end part inserted into and connected with the other end part of the first conveyance cylinder 20, and being freely telescopic in an axial direction a telescopic drive device 40 arranged on the one end part of the second conveyance cylinder 30 or the other end part of the first conveyance cylinder 20 and allowing the second conveyance cylinder 30 to perform a telescopic motion and a blowing device 60 for conveying the grains stored in the grain tank 7 via the first conveyance cylinder 20 and second conveyance cylinder 30. The second conveyance cylinder 30 has a double cylinder structure allowing an inner side cylinder 32 to freely advance/retreat with respect to an outer side cylinder 31. The telescopic drive device 40 allows the outer side cylinder 31 to advance/retreat with respect to the inner side cylinder 32, causing the second conveyance cylinder 30 to perform the telescopic motion.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】穀粒をより容易に排出可能なコンバインを提供すること。【解決手段】コンバイン1は、機体フレーム2上に配設され、穀粒を貯留するグレンタンク7と、機体フレーム2の後方に配設され、一端部がグレンタンク7に接続された第1搬送筒20と、機体フレーム2上の上部に配設され、一端部が第1搬送筒20の他端部に挿入されて接続され、軸方向に伸縮自在な第2搬送筒30と、第2搬送筒30の一端部、または、第1搬送筒20の他端部に配設され、第2搬送筒30を伸縮させる伸縮駆動装置40と、グレンタンク7に貯留された穀粒を、第1搬送筒20と第2搬送筒30とを介して搬送するための送風装置60とを備える。第2搬送筒30は、外側筒31に内側筒32が進退自在に挿入された二重筒構造であり、伸縮駆動装置40は、内側筒32に対して外側筒31を進退させて、第2搬送筒30を伸縮させる。【選択図】図1
