Description

Corn harvesting station and corn combine harvester with the same

The present invention relates to an agricultural harvesting machine, and more particularly to a corn combine harvester.

At present, most of the picking and slab-type corn harvesting stations use the traditional chain-type transmission mechanism to feed the corn plants and transport the corn ears. This mechanism has a poor lateral effect on the corn plants and needs to be harvested. Otherwise, it is easy to push down or break the corn plant, causing loss of ear, and because the finger on the conveyor chain has a greater impact on the corn ear, it is easy to damage the grain on the corn ear. Some corn harvesters use the Hexingxing wheel to complete the feeding of corn plants and the transportation of corn ears. This kind of Hexingxing wheel uses the adjacent two rounds of the same direction of rotation, and dials the Wo The fingers can not be interlaced, the spacing between the dividers is large, and the horizontal spacing is poor. When the row spacing of the corn plant varies greatly, it is easy to push down the corn plants and cause ear loss. The lateral harvesting effects of the above two corn harvesting platforms are not ideal and are not suitable for the harvest of narrow-line corn. Especially in the latter type of corn harvesting station, the width of the divider is relatively large. In order to obtain a smaller angle of division, it is necessary to lengthen the length of the divider, the mass is larger, and the resistance of the divider is larger, which affects the division.
