The divider 33 and the weeding frame 34 are fitted and connected so as to be extendable and contractible, and the amount of protrusion can be freely adjusted by operating the set bolt 36.

[0010] The main function of the harvesting operation is as follows. The ginseng in the ground is pulled out by holding the leaves with the strong pinching force of the belt front end portion 11a and lifting it upward and backward, and then the belt intermediate portion 11b. The ginseng is transferred rearward and upward by the conveying force of the aligning and conveying device 4 by the belt rear half 11c and the guide mechanism 12. However, since the inclination of the guide mechanism 12 is gentle, the upper surface of the ginseng body gradually becomes smaller. After approaching the roller 14, the rear portion of the guide mechanism 12 is brought into a contact conveyance state in which the upper surface of the ginseng body contacts the roller 14. Thereafter, due to the weak pinching force of the belt rear half portion 11b, the rearward conveying force is allowed to pass through to the ginseng and move downward through the leaves, so that the end of the conveying belt 11 has Always comes into contact and transport. Then, by slightly holding the upper portion of the base of the leaf portion by the re-holding and conveying device, the leaf cutting portion of the leaf cutting device 3 can be set to be at a position just below the base. The cut leaves are discharged to the rear of the fuselage by the chute 27, and the ginseng body is transported to the container 24 by the guide plate 25.
