Process flow: Use corn harvester to pick ears when corn is growing (called standing stalk picking). Under the action of picking roller and picking plate, the ear handle is pulled off. Due to the height difference between the inner and outer picking rollers, the ears fall into the ear box. After the ears are full, the box is opened and piled.
