Cutting and feed arrangement for harvester has coaxial feed discs positioned above cutting disc for rotation about vertical axis

摘要

The invention relates to clearing elements for the cutting and transport devices of a maize cutting system that operates independently of the rows of maize. The aim of the invention is to provide clearing elements, which have no negative effects on either the structural configuration or the function of other components in the cutting system, require a minimum amount of space, are light and can be produced at low cost. To achieve this, a continuous belt drive (27) that rotates on an essentially horizontal plane is located solely in the vicinity of the delivery point (4) of the cutting and transport device (2). One end of said continuous belt drive (27) is guided around an interior deflection pulley (29), whose surface (35) lies within and in close proximity to the rotational circle (36) of the transport discs (11; 11') and the other end of the continuous belt drive (27) is guided around an exterior deflection pulley (28), whose surface (38) lies outside said rotational circle (36). The followers (30) that are juxtaposed on the continuous belt drive (27) are provided for clearing adjacent transport pockets (13; 13') in the transport discs (11; 11').
