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 include some flat cutting blades and some twisted blade members which have a planar base portion attached to the lug, an outer planar blade portion and an intermediate twisted portion twisted about a center line so that the blade portion lies at an angle to the base portion. Where the angle is less than 90 degrees, the blade portion defines a leading edge and a trailing edge lying in two different axially spaced planes and the blade portion tends to generate air flow in an axial direction. Two such blades arranged with opposite angles can be carried on the same lug. Where the blades are arranged adjacent an end of the hub, the blades can be arranged with the angle tending to direct the air toward the same end thus assisting in moving the chopped material outwardly to one side of the combine.
