A combine harvester includes a housing having a rear hood and defining an interior, a blower for generating an air stream in a substantially rearward direction, and a cleaning system separating residue from a crop material such that the residue is transported via the air stream rearwardly to be discharged from the housing. A chopper rotor assembly is disposed within the interior below the rear hood and includes a chopper rotor having a plurality of blades for chopping the residue as it is received via the air stream. A chopper housing is disposed within the interior and defines an inlet of the chopper rotor for receiving the residue and an outlet spaced rearward from the chopper rotor for discharge of the chopped residue from the interior of the housing. An air gap through which the air stream may exit the interior is defined between the rear hood and chopper rotor.

Cross vented residue disposal system for an enclosed combine body

An agricultural combine has a chassis that supports a feederhouse receiving cut crop material from an agricultural harvesting head. A rotor and concave arrangement receives the cut crop material to thresh the cut crop material and to separate the cut crop material into a flow of grain and a flow of straw. A cleaning shoe receives the flow of grain from the threshing and separating mechanism to clean the flow of grain and to provide a flow of clean grain and a flow of chaff. A residue management system receives the flow of straw and the flow of chaff. The residue management system has a straw chopper that rotates in a first direction in a windrowing mode to windrow the flow of straw and rotates in a second direction opposite the first direction in a chopping mode to chop the flow of straw.

A combine harvester has a straw chute with a straw conveyor which comprises a conveyor rotor which can be set into rotation and has dogs distributed helically around the conveyor rotor.

Combine harvester with a straw chute and a straw conveyor

A combine harvester includes a housing having a rear hood and defining an interior, a blower for generating an air stream in a substantially rearward direction, and a cleaning system separating residue from a crop material such that the residue is transported via the air stream rearwardly to be discharged from the housing. A chopper rotor assembly is disposed within the interior below the rear hood and includes a chopper rotor having a plurality of blades for chopping the residue as it is received via the air stream. A chopper housing is disposed within the interior and includes a roof structure located above the chopper rotor such that a minimal gap is defined therebetween. The air stream flows out of the interior via a flow path defined through the chopper rotor without being substantially redirected from flowing in the rearward direction by the plurality of blades of the chopper rotor.

Cleaning shoe venting through chopper rotor assembly

A combine () includes a cleaning system () and an air conduit (), which air conduit is arranged outside of a side wall () and through which the cleaning air is conducted downstream of the cleaning screens () to a suction blower () of the straw chopper (), which suction blower is driven by a drive shaft ().
