In this way, by providing the guide plate 81, the straw waste can be discharged to the outside of the machine without being mixed into the carrier 50 and the swing sorting device 27.
- the installation of the guide plate 81 is optional and may function as a combine without the installation.
- a processing cylinder is arranged at the rear of the handling cylinder of the threshing apparatus, grains and dust after processing are arranged below the processing cylinder by a transport body, and a branch stalk processing apparatus is arranged in front of the processing cylinder.
- a branch stalk processing apparatus is arranged in front of the processing cylinder.
