Abstract:
A variably positionable chaff pan for attachment to an oscillating element of cleaning apparatus of an agricultural combine for oscillation therewith for conveying chaff from the oscillating element to a non-oscillating chopper or spreader mounted to a fixed frame of the combine, comprising:a pan having a surface for receiving the chaff positionable adjacent to the oscillating element of the cleaning apparatus for receiving the chaff therefrom; a pivoting element for connecting the can to the oscillating element for pivotal movement relative thereto about a generally horizontal axis through a range of positions angularly related to the oscillating element including positions oriented relative thereto for receiving the chaff therefrom; and a linkage arrangement connecting the pan to the fixed frame for supporting the pan in selected ones of the positions within the range of positions while allowing the pan to oscillate with the oscillating element relative to the linkage arrangement, the linkage arrangement including a locking variable length element lockable a lengths within a range of lengths for holding the pan in the positions for receiving the chaff from the oscillating element, respectively, and unlockable such that the length can be varied to allow pivotal movement of the pan to other of the positions within the range of positions, wherein the locking variable length element supports a lever arm pivotally connected to the fixed frame and to the pan.
