Abstract
A combine harvester including a frame, threshing apparatus, a grain cleaning system, and, a feederhouse pivotally mounted to the frame on a transverse lift axis. The feederhouse includes a conveyor for conveying cut crop material from a fore opening to an aft opening. The feederhouse is configured to support a cutting header at its forward end. The grain cleaning system includes a transverse cross-flow fan having a debris screen protecting an air inlet channel. The debris screen includes a plurality of elongate transverse screen elements each being mounted to the frame so as to provide a degree of vertical movement freedom with respect to the frame. At least one elastic member is connected between the underside of the feederhouse and the frame and connects the plurality of screen elements. At least one elastic member is stretched as the feederhouse is raised and the vertical spacing between the plurality of screen elements increases.
