Abstract

In a rotational sphere press for agricultural grain stem products, the wrapping area of which is limited by rotating conveyor rollers, and which has a pre-chamber, a first conveyor mechanism is provided for tranporting the harvested product into the pre-chamber and a second conveyor mechanism is provided for transporting the harvested product from the pre-chamber through a feed hold between two neighboring conveyor rollers into the wrapping area. The second conveyor mechanism has a conveyor drum which is axially parallel to the conveyor rollers and which can be moved perpendicular to an opposite-positioned counterbearing by overcoming the reset force of a reset element within a pre-given motional path. The conveyor drum has driving plate pins which are in the rear area facing the feed hole and neighboring the exteral surface of the drum. They project outwardly, perpendicular to the external surface of the drum in the front and lower area. The driving plate pins are designed for blocking off the harvested product flow into the feed hole.
