PROBLEM TO BE SOLVED: To reduce the occurrences of grain damages and grain clogging.SOLUTION: The combine harvester is equipped with a threshing machine 3 located above the running apparatus 2 of the combine harvester, a grain tank 20 at the side of the threshing machine 3, and an unloading apparatus 21 in the grain tank 20. The end of the unloading apparatus 21 is connected to the horizontal cylindrical part 26 of a connecting member 22 and the lower part of an unloading vertical grain lifting apparatus 25 is connected to the vertical cylindrical part 27 of the connecting member 22. The shaft center of the vertical cylindrical part 27 is removed from the upper part of the shaft center of the horizontal cylindrical part 26, arranged at one side and made to communicate with the horizontal cylindrical part 26 by a communicating hole 30. An input pulley 41 is arranged at one end of a rotary input shaft 40, that is to be pivotally mounted on the horizontal cylindrical part 26； a bevel gear 42 is installed behind the communicating hole 30 of the rotary input shaft 26； and the bevel gear 42 is engaged with a bevel gear 43 fixed to a vertical shaft 44. An endless chain 48 is hung between a transmission sprocket 45 at the lower part of the vertical shaft 44 and the transmission sprocket 47 of the grain lifting shaft 46 of the unloading vertical grain lifting apparatus 25.COPYRIGHT: (C)2008,JPO&INPIT【課題】穀粒の損傷、穀粒の詰まり発生。【解決手段】コンバインの走行装置２の上方に脱穀装置３を、脱穀装置３の側方にグレンタンク２０を、グレンタンク２０内に排出装置２１を設ける。排出装置２１の終端は接続部材２２の横筒部２６に接続し、接続部材２２の縦筒部２７には排出用縦揚穀装置２５の下部を接続し、縦筒部２７はその軸芯を前記横筒部２６の軸芯上方から外した一側に配置して連通口３０により前記横筒部２６と連通させる。横筒部２６に軸装する回転入力軸４０の一端に入力プーリ４１を設け、回転入力軸４０の連通口３０の後側に傘歯車４２を設け、傘歯車４２には縦軸４４に固定の傘歯車４３を噛み合わせる。縦軸４４の下部の伝動スプロケット４５と、排出用縦揚穀装置２５の揚穀軸４６の伝動スプロケット４７との間に無端チエン４８を掛け回す。【選択図】図４
