PROBLEM TO BE SOLVED: To improve a grain transfer efficiency from a vertical auger to a horizontal auger while stabilizing a rotary action of the horizontal auger to the vertical auger.SOLUTION: In a state in which an inlet of a horizontal auger tube is joined to an outlet of the vertical auger, the horizontal auger cylinder is connected to the vertical auger cylinder rotatably around the center of outlet, and a vertical conveying shaft is equipped with a release blade at a point lower than the center of the outlet and in a manner that at least a part of the release blade faces the outlet. A transmission shaft having one end part operably connected to a vertical shaft body and the other end extended to the outside of the horizontal auger cylinder from the opposite side of the vertical auger cylinder is arranged coaxially with the outlet and the inlet. The horizontal auger cylinder is equipped with a transmission unit for operably connecting the other end part of the transmission shaft to the base end part of a horizontal shaft body, and the transmission shaft is equipped with a pushing blade at least partially overlapping a horizontal conveying shaft with respect to a shaft line direction position.COPYRIGHT: (C)2013,JPO&INPIT【課題】横オーガの縦オーガに対する回動動作の安定化を図りつつ縦オーガから横オーガへの穀粒移送効率の向上を図る。【解決手段】横オーガ筒の受入口が縦オーガ筒の放出口に接合された状態で横オーガ筒が縦オーガ筒に放出口の中心回り回動可能に連結され、縦搬送軸には放出口の中心より下方で且つ少なくとも一部が放出口に臨むように放出羽根が設けられている。一端部が縦軸体に作動連結され且つ他端部が横オーガ筒の縦オーガ筒とは反対側から外方へ延在された伝動軸が放出口及び受入口と同心上に配置されている。伝動軸の他端部を横軸体の基端部に作動連結する伝動ユニットが横オーガ筒に設けられており、伝動軸には軸線方向位置に関し横搬送軸と少なくとも部分的にオーバーラップする押し込み羽根が設けられている。【選択図】図8
