Corn harvester with ear plucking roller having winding-prevention device

The invention relates to the technical field of agricultural machinery, specifically to a corn harvester with an ear plucking roller having a winding-prevention device. The corn harvester comprises a frame, and the ear plucking roller is installed on the frame. The corn harvester is characterized in that a protection plate is installed on the frame under the ear plucking roller, the outer edge of the protection plate is parallel to the shaft core of the ear plucking roller, and the outer edge of the protection plate is close to the ear plucking roller and has a cutting edge portion. The corn harvester can prevent corn straws from winding on the ear plucking roller and realizes smooth harvesting. The outer edge of the protection plate has a cutting edge portion which can cut off winding corn straws. The use effect is better.
