PROBLEM TO BE SOLVED: To heighten operability of a conveying cylinder in grain discharge work.SOLUTION: A conveying cylinder (6) and a third cylindrical member (7) provided below the conveying cylinder (6) are supported to freely hinge on a first shaft center (Y) in a longitudinal direction, and a lock plate (12) turned in a body with the third cylindrical member (7) is provided with a lock pin (13). A plurality of holes (14) are formed in a support member (11) fixed to a machine body frame (3) side, and a recessed part (15) is formed on a rear side face of the third cylindrical member (7). A hinged turning position of the conveying cylinder (6) is controlled gradually by engaging the lock pin (13) with the recessed part (15) through the holes (14).COPYRIGHT: (C)2014,JPO&INPIT【課題】穀粒排出作業における搬送筒の操作性を高める。【解決手段】搬送筒(6)及び該搬送筒(6)の下部に備える第3筒部材(7)を前後方向の第1軸心(Y)回りに起伏回動自在に支持し、第3筒部材(7)と一体で回動するロックプレート(12)にロックピン(13)を備え、機体フレーム(3)側に固定した支持部材(11)には複数の孔(14)を形成し、第3筒部材(7)の後側面には凹部(15)を形成し、ロックピン(13)が孔(14)を貫通して凹部(15)に係合することで、搬送筒(6)の起伏回動位置が段階的に調節される構成とすることにより解決される。【選択図】図2
