Abstract
A release mechanism for a combine stone trap latch is disclosed wherein the detection of a stone in the crop feed path by either electronic or mechanical detection mechanisms can trigger the release of the latch from a trap door to permit the stone to be ejected from the feed path. The mechanical detection mechamism includes a pinch roller rotatably mounted on a bearing plate above the trap door for movement to selectively vary the distance between the pinch roller and the trap door. A trip link operatively associated with the electronic detection mechanism is pivotally mounted on the bearing plate to maintain a fixed positional relationship between the trip link and a cam member affixed to the pinch roller whenever the pinch roller is positionally adjusted. The release mechanism operatively cooperates with the trip link when the electronic detection mechanism senses a stone in the feed path to unlatch the trap door without the need for adjustment when the bearing plate is moved to adjust the position of the pinch roller relative to the trap door.
