An improved feeder device for combine-harvesters of the type having a header and a straw-elevator for harvesting and conveying the harvested crops to crop handling components such as threshing and separating devices. A guide plate is provided between the discharge end of the straw-elevator and the intake portion of the threshing equipment for guiding the crop material from the straw-elevator to the threshing equipment; said guide plate being hinged to a fixed portion of the machine and supported by supporting means, which themselves are kinematically interconnected, so that, on the entrance of a stone or other foreign object towards the threshing equipment, said supporting means are automatically and simultaneously displaced by the stone or other foreign object beating on said plate so as to enable the guide plate to hinge to a position whereby a stone retarder or stone trap is formed.
