A frame is adapted to be supported on the inside surface of a peripheral wall of the silo and to be lowered in said silo when silage has been removed. A unit is carried by said frame and mounted for rotation on a vertical axis at the center of said frame and comprises a radially extending cutting and feeding screw provided at its periphery with cutting and tearing elements. The unit also comprises an ejecting blower disposed radially inwardly of said screw and comprising an impeller and an inake opening which faces said screw and is at least as large in diameter as said screw and exposed throughout its periphery. The unit further comprises drive means for driving said screw and blower. The drive means comprise a hollow shaft which carries said impeller and is operable to rotate the same, and a drive shaft which extends through said hollow shaft and is operatively connected to said screw.
