Combine having cleaning venting by a suction blower driven by the straw chopper shaft

A combine (10) comprises:

• a supporting structure (12), on the front side of which an inclined conveyor (20) is mounted;
• a threshing and separating device mounted inside the supporting structure (12) and comprising a crop residue outlet through which crop residues can be fed to a straw chopper (68);
• a cleaning system (28) to which grain separated by the threshing and separating device can be supplied and which is equipped with a cleaning blower (46) for generating an air flow, and at least one cleaning screen (48, 50, 66), to which the air flow can be applied and which can be set into an oscillating motion to separate grain and chaff;
• and
• an air conduit (80) that extends between an inlet (82), arranged downstream of the at least one cleaning screen (48, 50, 66) in relation to the air flow, and a suction blower (86), characterized in that the air conduit (80) is situated on the outer side of a side wall (78) of the cleaning system (28) and in that the suction blower (86) is arranged coaxially with a drive shaft (96) of the straw chopper (68) and is drivingly connected thereto.
