Stone trap for a combine harvester

摘要

A combine harvester stone trap having its upwardly facing inlet generally in the proximity of the transition between the discharge end of the crop elevator and the forward end of the combine threshing concave. The stone trap includes a front wall in the form of a door which can be opened into a retracted position for emptying the stone trap and a rear wall which, in an operative position, effectively closes the gap between the forward end of the threshing concave and the forward end of the combine grain pan located below the concave in a conventional manner. The rear wall is movable into an inoperative position providing access to the gap between the forward ends of the threshing concave and the grain pan.
