PROBLEM TO BE SOLVED: To quickly discharge grains which are high in water content, in a combine which discharges the grains in a grain tank by air transfer.SOLUTION: Grains are made to flow down to a payout device (13) in a lower part from a flow-down port (6a) of a grain tank (6) a transfer cylinder (15) is arranged at a lower part of the payout device (13) the grains paid out of the payout device (13) are made to flow down to the transfer cylinder (15), and blown to a starting end side of the transfer cylinder (15) via a blower cylinder (18) from a blower device (17) a starting end side of a flexible discharge cylinder (21) is connected to a terminal end side of the transfer cylinder (15) the grains in the grain tank (6) are discharged by a wind force from the blower device (17) and the grains in the vicinity of the flow-down port (6a) are loosened and scraped out to the flow-down port (6a) by a scrape-out fall-down device (23) arranged in the vicinity of an upper part of the flow-down port (6a) of the grain tank (6), and supplied to the payout device (13) in the lower part.COPYRIGHT: (C)2015,JPO&INPIT【課題】グレンタンクの穀粒を空気搬送により排出するコンバインにおいて、高水分の穀粒を迅速に排出する。【解決手段】グレンタンク(6)の流下口(6a)から下方の繰出装置(13)に穀粒を流下可能に構成し、該繰出装置(13)の下方に搬送筒(15)を配設し繰出装置(13)から繰り出した穀粒を搬送筒(15)に流下可能に構成し、送風装置(17)から送風筒(18)を経由して前記搬送筒(15)の始端側に送風し、前記搬送筒(15)の終端側に可撓性の排出筒(21)の始端側を接続し、送風装置(17)からの風力によりグレンタンク(6)の穀粒を風力で排出するように構成し、前記グレンタンク(6)の流下口(6a)の上方近傍に配設している掻出落下装置(23)により流下口(6a)近傍の穀粒をほぐしながら流下口(6a)に掻き出し下方の繰出装置(13)に供給する。【選択図】図4
