[A] [B] When the wind generated due to the rotation of the handling cylinder is guided by the guide surface to the front end of the handling cylinder in the circumferential direction of the handling cylinder, the generated wind is caught in the working peripheral end side of the handling cylinder. Therefore, it is difficult to come out of the handling room to the front side, and it is difficult to flow into the cylindrical body. Therefore, when harvesting rice and wheat, the harvested culm is formed into a cylindrical body so that it does not easily enter or flow and clogging does not easily occur. Even if the cylindrical body has a large grain stalk receiving port and a large cross-sectional area, dust can easily flow in the cylindrical body, and even if the dust generated in the cylindrical body increases, Dust flows due to the wind generated in the room are less likely to occur, and the dust is less likely to leak out of the cylindrical body. [B] The guide of the generated wind is on the lower side in the feed direction of the processed material.
