Abstract
A rock door has its front end pivotally mounted on a combine near the crop inlet to the threshing cage and when closed has a pivoted lip structure at its rear end resting on the front end of the threshing concave. The lip structure is releasably held in its normal operating position by a latching mechanism employing a pair of oppositely acting spring biased roller detents engaging opposite sides of a detent finger carried by the lip structure. When a rock of substantial size is conveyed to the gap between the threshing rotor and the door, the force of the rock against the door causes the latch mechanism to release the door allowing the rock to be discharged.
