A grain cleaning system in a combine harvester including a frame, a chaffer sieve, and a lower sieve. A clean grain chute is located under the lower sieve to catch grain falling therefrom and is inclined to direct the caught grain to a clean grain trough. A tailings return chute is disposed under the clean grain chute and is configured to direct tailings to a tailings collection trough. A multi-configurable plate is mounted to the frame and positioned under a rear portion of the chaffer sieve. The plate is moveable between different operating positions. In a first operating position the plate is configured to guide material incident thereon to the tailings return chute. In a second operating position the plate is configured to guide material incident thereon to the clean grain chute.

Grain cleaning system in a combine harvester

A combine harvester including threshing and separating apparatus which are arranged to process a cut crop stream and each having a grate arrangement through which material separated from the crop stream falls under gravity. Grain conveyance means arranged below the threshing and separating apparatus catch the falling grain and material other than grain (MOG). A stratification pan is located below a front region of the threshing and separating apparatus and a return conveyor is located below a rear region of the threshing and separating apparatus, both conveyors being driven in a oscillating manner. The return conveyor conveys said grain and MOG in a forward direction to a front edge thereof which is located above the stratification pan. The stratification pan conveys collected material rearwardly to a rear edge from where the collected material falls under gravity into a cleaning unit. An accelerator roller is provided and is rotatably driven on a transverse axis in front of the front edge of the return conveyor. Material caught by the return conveyor is incident upon the accelerator roller and paddles provided on the accelerator roller serve to accelerate the material from the return conveyor forwardly.
