Combine harvester and discharge assembly of the same

A combine harvester comprising:

• a housing;
• a separating system mounted within the housing for separating a seed material from a straw material;
• a spreading system including an inlet and at least one outlet configured to disperse the straw material outside of the housing of the combine harvester;
• and
• an air discharge channel including an air inlet positioned above the inlet of the spreading system, and an air outlet,
• wherein the channel defines a path extending upward from the air inlet to inhibit the straw material from entering the air inlet and downward toward the air outlet between the air inlet and the air outlet.

A discharge assembly of a combine harvester, the discharge assembly comprising:

• a straw chopper located within a housing of the combine harvester and operable to chop a straw material;
• a spreading system positioned downstream of the straw chopper and configured to discharge the straw material through a first outlet;
• and
• an air discharge channel located between the straw chopper and the spreading system, the air discharge channel configured to discharge an airflow separate from the straw material through a second outlet when the spreading system is configured to discharge the straw material through the first outlet.
