〔Effect of the invention〕

According to the present invention, it is possible to cut the stems and leaves, collect the film, and harvest the tuber crops in one process. At this time, the film processing mechanism that processes the film grips the film and sends it out backwards. Equipped with a rotatable upper and lower feed roller and a cutter that shreds the film sent out by the upper and lower feed rollers, this film processing mechanism ensures that the film collected in the upper part of the ridge is sequentially processed. It can be shredded into pieces.

Furthermore, the dividers on both sides that guide the film to the film processing mechanism have raised surfaces that push up the film and guiding surfaces that guide both sides of the film inward. In addition to being able to reliably push the film up from the ridges, the width of the film can be narrowed on the guiding surface and guided toward the film processing mechanism. It is possible to reliably prevent the parts from getting caught on members such as the machine frame.

Further, since a collecting body for collecting the film fragments is provided, the film fragments shredded by the film processing mechanism can be reliably collected by the collecting body without scattering them.

In addition, when the film is sequentially wound and collected by a take-up roller, the film may be torn in the middle, the collection of a certain length of film must be interrupted, and it is time-consuming to remove the film from the take-up roller. Never.

Therefore, it is possible to highly efficiently harvest tuber crops grown in multi-culture, and to easily collect the film, thereby providing a harvesting device with excellent workability.
