Abstract
A chopper and discharge apparatus includes a stationary housing for attachment to the rear discharge of a combine harvester so that straw is fed from the combine into an inlet of the housing and is discharged from an outlet of the housing. Within the housing is mounted a hub for rotation about the horizontal axis with the hub carrying a plurality of lugs at angularly and axially spaced positions therearound, each lug carrying a pair of pivotal blade members which are rotated with the hub in the form of flails. Each lug is associated with a stationary blade on the inside of the housing so that the pair of blades carried on each lug sweep past the stationary blade each on a respective side of the stationary blade. The blade members includes some flat cutting blades and some fan blade members which have a flap portion at a trailing edge of the blade which is bent outwardly at right angles and is also inclined outwardly and forwardly to generate a fan action in the air carried by the blade. There are more flat blades adjacent a center of the hub than adjacent the ends of the hub to increase fan action at the ends of the hub for increased discharge velocity.
The fan blades include a connection which is offset to locate the center of gravity directly radially outwardly from the mounting on the lug.
