Design and Simulation of the Picking Roll of the Corn Harvester

The header is the most important part of the corn harvest, and the structure of the stripping roller determines the results of stripping and stalk pulling. In order to improve the efficiency and integrity of harvesting, a new type of harvesting roller was designed. Based on the working principle of the snapping roll, the spiral round steel and the snapping claw are welded on the body of the snapping roll in the way of straw feeding and entering the snapping roll under the action of the grain divider. In order to verify the rationality, the snapping roll was simulated to verify the rationality of the structure design.
