By understanding its composition, working principle, characteristics and advantages, as well as usage and maintenance recommendations, we can better play the role of the corn harvester and improve agricultural production efficiency and quality.

[0003] When harvesting corn, the existing corn harvester device needs to use the harvesting device at the front end of the harvester to aim at the low area of ​​the corn, and use the separator and harvesting knife on the harvesting device to divide and collect the corn berries on the corn stalks while the harvester moves forward. However, during the harvesting process, the broken leaves of the corn stalks often stick to the harvesting device, affecting the subsequent harvesting speed and the cleanliness of the device, which requires cleaning work. When cleaning the surface of the harvesting device, the clean water level in the water tank needs to be monitored to facilitate the staff to understand the water level of the water tank. Therefore, a harvesting device for corn harvesters that solves the above problems is needed. Summary of the Invention
