1. Adopting a composite cutting platform, both ear picking and straw harvesting are completed simultaneously (the upper cutting platform consists of a cutting blade for ear picking, a supporting mechanism, and a strong feeding structure; the lower cutting platform consists of a reciprocating cutting blade and a chain rake conveying system). The upper and lower cutting platforms can adjust the harvesting height separately according to the crop situation in different harvesting areas
