Abstract
A spout of an agricultural ejector is mounted on the ejector housing for angular displacement about an axis. An planetary gear transmission is interposed between the spout and the housing and has one bevel gear stationarily connected to the housing and another bevel gear connected to the spout for rotation therewith. A bevel pinion is mounted on a sleeve for rotation about its own axis and for orbiting about the axis of the spout in meshing engagement with the bevel gears. A cylinder and piston unit is pivotably connected to the housing and to the sleeve and rotates the sleeve so that the planetary gear transmission causes the spout to rotate at twice the angular speed of the sleeve. In this manner, the direction in which the spout ejects can be rapidly changed.
