[0054] When the corn harvesting round bale baler of the present embodiment is in use, the corn cobs are peeled on the multifunctional cutting platform 1 and collected into the cob box 4 via the elevator 3, the stalks are shredded on the multifunctional cutting platform 1 and transported to the grass receiving box 5 at the rear via the connecting pipe, and then enter the baler 6 for baling, thus realizing non-stop continuous operation.

[0055] In this embodiment, the vehicle body includes a cab 2, and the ear box 4 is located behind the cab 2, thereby improving the compactness of the structure and shortening the overall length.

[0056] There are many structures of the elevator 3, and those skilled in the art can choose according to their needs. In this embodiment, the elevator 3 includes a driving sprocket 63, a conveying chain 64, a scraper 65, an elevator housing 66, a driving shaft 67, and a driven shaft 68.
