Thus, the number of parts can be reduced and the weight can be reduced by a simple transmission configuration.

  The remaining leaf processing device 4 arranged on the outer side reliably moves the discharged crop to the guide shooter side by projecting the entraining roller 12 beyond the side edge of the takeover transport mechanism 11 and projecting upward from the sorting transport device 5. Since it can be discharged to a position away from the take-up and transport mechanism 11, 11, it can be prevented that the crops collide with each other and get damaged, and the product value is prevented from being lowered. Since the discharged crops are transferred from the side edges of the takeover transport mechanisms 11 and 11 to the sorting and transporting device 5, the crops are prevented from colliding with each other and being damaged and the commercial value is prevented from being lowered.

The partition member pivotally supports the start end portion on the discharge-side shaft end portion of the winding roller 12 at the outer position, and at least the inner and outer positions of the winding rollers 12 and 12 at the inner and outer positions along the conveying direction of the sorting and conveying device 5. The partition member is arranged on the inner side from the discharge-side shaft end position of the winding roller 12 at the outer position by forming the terminal member at the same length as the interval distance and allowing the terminal end side to be rotated above the sorting and conveying device 5. Since the transport lane is partitioned for the sorting transport process up to the shaft end position of the winding roller 12, the contact due to the merging of crops can be prevented, so that the product value is prevented from being lowered due to contact scratches or the like.
Further, by rotating the end of the partition member above the sorting and conveying device 5, it is possible to prevent the partition member from interfering with the conveyance of the crop when the number of crops is small or the size of the crop is large.

  A protrusion 14 b is provided on the lower edge of the partition member 14, and irregularities that can be intermittently contacted with the protrusion 14 b are formed along the conveying direction of the conveying surface of the sorting and conveying apparatus 5. Is activated, the irregularities formed along the conveying direction of the conveying surface move and act on the protrusion 14b on the lower edge of the partition member 14 to swing the partition member 14 up and down. Even if it touches, since conveyance movement is promoted without adhering, the stagnation of the crop during conveyance is prevented and work efficiency improves.
