[0002] Corn is an important food crop and feed crop, and also the crop with the highest total output in the world. Its planting area and total output are second only to rice and wheat. After corn matures, it needs to be collected by agricultural machinery. For example, the patent with patent announcement number CN213485776U records a harvester for green organic corn. The recorded solution can unify the corn stalks in front of the equipment through a guide rod, twist the corn stalks backward through a rotating disk, push the corn stalks backward through a movable plate, and provide backward and downward force to the corn stalks through a spiral rod, so that it can be pulled downward. The corn stalks can be broken into pieces by a high-speed rotating blade. The corn bundle is driven by the movable plate and slides out through a slide and falls into a storage box, thereby realizing automation. However, in this case, only one storage box is provided, and the single storage space is limited. At the same time, the corn stalks broken by the high-speed rotating blade fall on the surface of the land, which is not conducive to the absorption of nutrients after the straw is returned to the field.
