Abstract (en)

[origin: WO2005102026A1] A combine harvester with a straw separating system and a sieve assembly below the straw separation system with a rear edge over which the chaff is discharged in the air flow has a housing with a rear hood behind the straw separating system and behind the rear edge of the sieve assembly with a bottom opening in the hood for discharge of the straw and the lighter materials. A straw chopper is mounted at the rear hood for receiving the straw and lighter materials and has a rotor for chopping the straw and for generating a stream of air and chopped straw for spreading the chopped straw. At least one vent opening with upwardly and outwardly inclined louvers is provided at the rear hood, either in the hood itself or in the side walls of the chopper housing, arranged to cause air from the sieve assembly to move rearwardly from the rear edge into the rear hood and to discharge from the rear hood through the at least one opening or allow air to be drawn in to satisfy the chopper requirements if the sieve airflow is lower. A fan can be provided to draw air from the opening and to supplement the air stream from the chopper
