Abstract
A foldable chaff pan for attachment to an oscillating element of a cleaning apparatus or system 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. The chaff pan is also sidewardly tiltable with the cleaning apparatus or system, if so capable.

A foldable 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 in a first position adjacent to the oscillating element of the cleaning apparatus for receiving the chaff therefrom;
- a pivoting element for connecting the pan to the oscillating element for oscillation therewith and pivotal movement relative thereto about a generally horizontal axis between the first position and a second position angularly related to and beneath the first position;
- and
- a linkage arrangement for connecting the pan to the fixed frame for supporting the pan in the first position, the linkage arrangement including a shaker arm connected to the pan and locatable in a support position for supporting the pan in the first position while allowing the pan to oscillate with the oscillating element relative to the linkage arrangement, and the linkage arrangement including a releasable spring element for holding the shaker arm in the support position and releasable to allow the shaker arm to move from the support position to another position to allow the pan to be folded to the second position.
A foldable chaff pan connected to cleaning apparatus mounted for oscillating movement relative to a frame of an agricultural combine for receiving chaff from the cleaning apparatus, the foldable chaff pan comprising:
- a pivot joint connecting the pan to the cleaning apparatus for oscillating movement with the cleaning apparatus, the pivot joint allowing pivotal movement of the pan relative to the cleaning apparatus about a generally horizontal pivotal axis;
- a shaker arm connected to the pan for supporting the pan in a first pivotal position relative to the cleaning apparatus for receiving the chaff therefrom;
- a lever arm pivotally mounted to the frame at a lever arm pivot and having a free end engageable with the shaker arm for holding the shaker arm in a position for supporting the pan in the first pivotal position;
- and
- a biasing element connected between the frame and the lever arm and in a position for releasably holding the lever arm in a position in engagement with the shaker arm for holding the shaker arm in the position for supporting the pan in the first pivotal position.

- and
- a linkage arrangement for connecting the pan to the fixed frame for supporting the pan in the first position, the linkage arrangement including a shaker arm having a first end connected to the pan and an opposite second end, the shaker arm being locatable in a support position for supporting the pan in the first position while allowing the pan to oscillate with the oscillating element relative to the shaker arm, a lever arm pivotally connected by a lever arm pivot to the fixed frame and releasably engageable with the second end of the shaker arm for supporting the shaker arm in the support position, and a biasing member disposed between the fixed frame and the lever arm biasing the lever arm into engagement with the shaker arm for supporting the pan in the first position.
