It extends to the lower part of the rear part of the trunk 21 and is horizontally provided in the left-right direction. The branch-branch processing cylinder 69 is housed in a cylinder 75. An opening is provided at the right rear part in the traveling direction of the cylinder 75 so as to communicate with the transport body 65. An opening 75a having substantially the same lateral width is provided and the upper part is opened, and a severance that overflows from the end side plate 59 of the handling cylinder 21 is received from the opening 75a. It is made to discharge on the swing sorting device 27.

  In such a configuration, the branch-branch processing drum 69 is driven to rotate in the clockwise direction when viewed from the left side in the aircraft advancing direction. When discharged from the discharge portion 75 b opened below the front portion of the cylindrical body 75, the flow is caused to flow forward by the flow of the wind due to the rotation of the branch raft processing drum 69, and is discharged to the front of the swing sorting device 27. The Therefore, it is possible to secure a sufficient distance for moving the oscillating sorting device 27, to diffuse the processed material to prevent the deviation, and to improve the sorting performance.
