Combine harvester

A combine harvester supported by a main chassis and comprising:

• a separating mechanism having a separating rotor cooperable with a separator housing including a separator concave and arranged spirally to convey crop material to at least one end thereof while submitting said crop material to a separating action;
• further crop treating means disposed below the separating mechanism for further handling separated grain;
• means defining together with the separator concave and open ended cavity having its open end facing to the further crop treating means for leading grain separated through said separator concave to said further crop treating means;
• an air inlet in the means defining the cavity at the upper portion thereof;
• the further crop treating means are formed by a grain cleaning mechanism;
• the means defining together with the separator concave said cavity comprise a deflector wall mounted at a distance from said concave;
• the separator concave and the deflector wall defining said cavity are both oriented generally in an upright direction;
• the open end of the cavity formed by the separator concave and the deflector wall is positioned at a short distance above the cleaning mechanism;
• and
• the top end of the cavity is formed by a shielding member of the chassis and wherein said air inlet is provided between said shielding member and said deflector wall.
