Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a corn harvester's field-returning mechanism. Background Technology

[0002] A corn harvester separates corn ears and stalks using a header. The separated stems and leaves fall directly from the header to the ground. The stalks that fall to the ground are currently mainly returned to the field. The corn harvester's stalk return machine is an agricultural machine used to effectively return stalks and residues to the field after corn harvesting. The main function of this equipment is to crush, evenly spread, and bury the corn stalks left after harvesting into the soil to improve soil quality, promote the increase of soil organic matter, and provide a good growing environment for subsequent crops.

[0003] In the existing technology, when the corn harvester's stalk-returning mechanism is working, the working height of the stalk-returning mechanism is adjusted by the harvester itself and cannot be adjusted according to the actual ground conditions. This results in insufficient crushing of the corn stalks, and the rollers of the stalk-returning mechanism may not be able to handle uneven ground during operation, leading to uneven soil after stalk return and reducing the stalk return effect. Therefore, a corn harvester's stalk-returning mechanism is proposed to solve the above problems. Utility Model Content
