CUTTING UNIT HAVING A BELT CONVEYOR DEVICE AND AIR OUTLET OPENINGS

摘要

The invention relates to a cutting unit (2) for attaching to a combine harvester, comprising a frame (4), a blade bar (6), belt conveyor devices (14) for conveying the cut stalk material away, and drive devices for driving the blade bar (6) and the belt conveyor devices (14). The problem addressed by the invention is that of reducing the loss of harvested material in the region of the step between the blade bar and the top side of the belt conveyor device. This problem is solved by a cutting unit having a belt conveyor device, wherein a sliding surface (11) inclined in the conveying direction of the harvested material is formed in the region of a height step between the blade bar (6) and the front edge of the top side of the belt conveyor devices (14), at the lower end of which sliding surface air outlet openings (12) are formed, each of which allows the associated exiting air flow to exit in a direction pointing upward or with which conducting elements (26) are associated, each of which conducts the associated exiting air flow in a direction pointing upward by means of the shape and arrangement of the conducting element.
