Field of the Invention The present invention comprises a processing chamber having a front end connected to a rear end of a handling chamber in which a handling drum is provided, through a dust passage. The present invention relates to a combine threshing apparatus in which a processing cylinder is provided in a processing chamber in parallel with a handling cylinder. 2. Description of the Related Art Conventionally, Japanese Unexamined Utility Model Publication No. 61-152237 discloses a technique for inserting and removing a processing cylinder behind a processing chamber. In the prior art, the processing cylinder is inserted into and removed from the rear of the processing chamber together with the processing cylinder shaft and the rear end of the processing chamber. Since it is extended to the front end and is supported by the front wall of the handling room, the processing cylinder shaft becomes almost the same length as the front and rear length of the threshing section, making it very difficult to insert and remove the processing cylinder. The required strength increases corresponding to the length of the
There was a problem that the vibration of the processing cylinder also became severe.
