Description

Corn harvesting platform and corn combine harvester with the corn harvesting platform

technical field

The utility model relates to an agricultural machine, in particular to a corn combine harvester.

Background technique

At present, most corn harvesting platforms use the traditional chain transmission mechanism to complete the feeding of corn plants and the transportation of corn ears. The finger has a greater impact on the ear of corn, and it is easy to damage the kernels on the ear of corn. Some corn harvesters use the reeling star wheel to complete the feeding of corn plants and the transportation of corn ears. This kind of reeling star wheel uses two adjacent wheels to rotate in the same direction. It means that they cannot be installed staggered with each other, the distance between the grain dividers is large, and the horizontal reeling effect is poor. When the row spacing of corn planting changes greatly, it is easy to push down the corn plants and cause ear loss. The horizontal reeling effects of the above two corn harvesting platforms are not ideal, and are not suitable for harvesting corn with narrow row spacing. Especially for the latter corn harvesting platform, the width of the grain divider is relatively large. In order to obtain a smaller grain division angle, the length of the grain divider needs to be lengthened, the mass is larger, and the grain division resistance is greater, which affects the grain division.
