Abstract

The stone trap for a combine harvester 10 includes an elevator to the cylinder 26, a beater assembly 40 rotatably mounted in the elevator and an opening 72 in the floor 38 of the elevator below the opening 72. A box 78 is mounted under the floor 38 to receive material that passes through the opening. Spring steel fingers 94 are bolted to the floor 38 at the forward edge 74 of the opening 72. The free ends of the fingers extend across the opening 72. The upper portion 104 of the rear wall 82 is a support to limit vertical movement of the free ends of the spring steel fingers 94. In operation, the free ends of the spring steel fingers 94 move to the side for the passage of stones driven into the box 78 by the beater assembly 40 and then spring back to hold stones in the box 78.
