Similarly, the second reel chain driving wheel 143 on the right side of the left middle ear picking unit 140 drives the reel chain to move, and forms a reel assembly with the reel chain in the second left ear picking unit 150 for righting the lodging and skewing corn plants, the left ear picking roller pair in the second left ear picking unit 150 cooperates with the ear picking plate to pick the corn ears, the picked corn ears also fall into the small left elevator 110, the small left elevator 110 conveys the corn ears to the upper header auger 100, and the corn ears finally enter the next process of the corn harvester through the upper header auger 100.

Similarly, the right ear picking mechanism and the right small elevator 120 on the right side of the upper header 1 have the same working principle as the left ear picking mechanism on the left side of the upper header 1.

For the lower header 2, the swinging ring cutter is a main part for cutting straws at the foremost edge of the header, the swinging ring cutter is controlled to reciprocate through the swinging ring box to cut the straws, and the cut straws are sent to the throwing air feeder by the lower header auger 200 to be discharged into the next process.

The foregoing is illustrative of the best mode of the utility model and details not described herein are within the common general knowledge of a person of ordinary skill in the art. The scope of the present invention is defined by the appended claims, and any equivalent modifications based on the technical teaching of the present invention are also within the scope of the present invention.
