APPARATUS FOR CHOPPING AND DISCHARGING STRAW FROM A COMBINE HARVESTER

摘要

A chopper and discharge apparatus includes a stationary housing (10) for attachment to the rear discharge of a combine harvester so that straw is fed from the combine into an inlet (15) of the housing and is discharged from an outlet (16) of the housing (10). Within the housing is mounted a hub (17) for rotation about the horizontal axis (18) with the hub carrying a plurality of lugs (21) at angularly and axially spaced positions therearound, each lug carrying a pair of pivotal blade members (19) which are rotated with the hub in the form of flails. Each lug is associated with a stationary blade (20) on the inside of the housing so that the pair of blades (19) carried on each lug sweep past the stationary blade (20) each on a respective side of the stationary blade. The blade members include some flat cutting blades in a center section and only fan blades (34) in end fan sections.
