PROBLEM TO BE SOLVED: To bring grain flow to be smooth to give no damage of grains, in a grain-conveying apparatus in which a transversely conveying screw conveyor and a vertically conveying screw conveyor are linked through a shaft supporting part inside of a transferring cylindrical body, by reducing a protrusion of the shaft supporting part toward the inside of the transferring cylindrical body to which the conveyed grains strike much as possible.SOLUTION: A final end part of a transverse shaft (10a) which is the rotary shaft of a transversely conveying screw conveyor (10) and a start end part of a vertical shaft (13a) of a vertically conveying screw conveyor (13) are respectively inserted through a transverse hole (12b) opening at a lateral side end part of a transferring cylindrical body (12) and a vertical hole (12c) opening at an upper side end part to pivotally support a shaft supporting part (12a) formed inside of the transferring cylindrical body (12), and a communication passages (B) leading to the transverse hole (12b) and the vertical hole (12c) are formed at a site on both right and left sides of the shaft supporting part (12a) in the inside of the transferring cylindrical body (12).COPYRIGHT: (C)2013,JPO&INPIT【課題】横送りスクリューコンベアと縦送りスクリューコンベアとが引継筒体内部の軸支部で連動された穀粒搬送装置において、搬送穀粒が当たる軸支部の引継筒体内部への突出部を出来るだけ小さくして穀粒の流れをスムースにして穀粒の損傷を無くす。【解決手段】横送りスクリューコンベア(10)の回転軸である横軸(10a)の終端部と、縦送りスクリューコンベア(13)の回転軸である縦軸(13a)の始端部との夫々を、引継筒体(12)の横側端部に開口した横孔(12b)と上側端部に開口した縦孔(12c)から挿入して引継筒体(12)の内部に形成した軸支部(12a)に軸支し、引継筒体(12)の内部における軸支部(12a)の左右両側の部位に、横孔(12b)と縦孔(12c)に通じる連通路(B)を形成する。【選択図】図5
