【Abstract】 In order to meet the requirements of harvesting both corn and stalk for a corn combine harvester, a vertical-roll corn picker with a stalk chopper was developed. A three-segment corn snapping roll was employed in the corn picker. The length calculation formula for each part of the corn snapping roll was developed and the selection gist and application limits of the main parameters were determined experimentally. The experiments and application of the combine harvester proved a good structure.更多还原
