PURPOSE: A combine is provided to rotate a grain storage unit including a return container repetitively rotating up-and-down in the circumference of the axis in a front and a rear of a body without interfering with a return container. CONSTITUTION: A combine includes a threshing apparatus(18) installed in one side of left and right sides of a body frame including a traveling apparatus(20)； a grain storage unit(1) and a grain discharge return container(6) installed in the left and right sides of a body frame； a maintenance unit installing the return container to be repetitively rotating up-and-down in a first axial circumference in the front and the rear directions of the body to support； a return screw formed between a front wall and a rear wall of the grain storage unit while opening a check unit in a upper wall of the grain storage unit； and a first container member front side unit fixed to the lower part of the rear wall of the storage unit.本發明提供一種聯合收割機，使具備繞機體前後方向的軸心起伏轉動的搬送筒的穀粒存積裝置不與搬送筒發生干擾地向機體外側方向轉動，從而提高維護的效率。在穀粒存積裝置(1)的前壁(1f)和後壁(28)之間具備搬送螺旋(8)，在穀粒存積裝置(1)的後壁(28)的下部固定第一筒部件(2)的前側部，第一筒部件(2)的後側部和固定於機體框架(3)側的第二筒部件(4)的前側部利用與第二軸心(Z)同軸心的第一縱軸(5)以能夠自如接合和分離的方式軸連接，第二筒部件(4)的後側部與在搬送筒(6)的基部具備的第三筒部件(7)的前側部以能夠繞與第一軸心(Y)同軸心的搬送螺旋(8)的軸心自如地相對轉動的方式接合。
