Technical Field

[0001] The utility model relates to the technical field of agricultural equipment, in particular to a corn harvester cleaning screen. Background Art

[0002] Corn harvester cleaning screen is an important component of the corn harvester. It is mainly used to clean and screen corn during the harvesting process to remove impurities such as weeds, soil, stones, etc., so as to improve the harvest rate and quality of corn. Through vibration or wind power, weeds, soil, stones and other impurities mixed in the corn are separated to ensure the purity of the harvested corn.

[0003] When corn is screened by vibration, the corn will continuously collide with the surface of the cleaning screen. When the corn particles collide with the surface of the cleaning screen for a long time, the surface of the cleaning screen will be damaged. The cleaning screen is welded to the frame, making it difficult to disassemble, maintain and replace the cleaning screen during maintenance.

[0004] For this reason, a corn harvester cleaning screen is proposed. Utility Model Content
