Abstract: In order to reclaim corn stalk, a structure unit combining vertical-roller corn picker with hob stalk shredder was put forward, and a harvesting technology combining corn picking, stalk shredding and stubble chopping was designed. This technology was applied to the 4YQZ-3 self-propelled corn combine harvester. Experiments and analyses showed it conformed to China national standard. Thus a technological scheme and an applied case were provided for solving the key problem of corn and stalk harvesting at the same time.
