초록 ▼

A straw and chaff chopping and discharge arrangement is attached to a rear discharge opening of a combine harvester. The discharge apparatus includes a horizontal hub member transverse to the combine and carrying upon it a plurality of blade members arranged in radial planes along the length of the hub member. Each blade member includes a support plate lying in a radial plane together with a transverse blade surface which is inclined so that it extends outwardly and forwardly to generate a high velocity of air rotating with the chopping assembly around the axis. A housing is shaped with a stripping edge at the discharge opening to cause the rotating air and chopped material to be expelled through the discharge opening upwardly and rearwardly from the housing. The material can be spread across the ground up to a width equal to the swath from which the crop has been cut to provide even spreading of the material across the ground. Alternatively the material can be discharged into a transportation wagon for collection.

A combine harvester comprising a combine harvester body, means for discharging separated straw from a rear discharge area of the combine harvester body, a chopper and discharge apparatus and means mounting the apparatus in the combine harvester body at a position adjacent the rear discharge area for receiving straw therefrom, the apparatus comprising a housing having a feed opening and a discharge opening, a chopping assembly mounted in the housing and comprising a hub member mounted for rotation about a longitudinal axis of the hub member and a plurality of blade members mounted on the hub member for rotation therewith about said axis, a plurality of stationary blades mounted in the housing in axially spaced positions therealong the stationary blades lying in parallel radial planes, each blade member projecting generally outwardly form the hub member in a radial plane of said axis, the blade members being arranged at spaced positions along the length of the hub member such that rotation of the hub member causes each of the blade members to pass between a respective two of the stationary blades in a cutting action, the feed opening being arranged longitudinally of the chopping assembly so as to deposit the material onto the chopping assembly in a direction generally inwardly toward the axis, the discharge opening being arranged longitudinally of the chopping assembly so as to allow discharge of the material generally radially outwardly from the chopping assembly, each of the blade members including a blade surface portion extending generally longitudinally of the axis and generally radial outwardly from the axis, the blade surface portion being inclined such that a radially outer part of the blade surface portion is arranged angularly forwardly of a radially inner part of the blade surface portion.
