The short root ginseng A is carried from the endless rolling body 12 to the upper traveling portion 14a of the conveyor belt 14 of the alignment conveyor 16 and is also conveyed by the conveyor belt 14 toward the foliage drawing roller 15. It Then, the short root ginseng A is blocked at the position of the foliage drawing roller 15 by the foliage drawing roller 15 to prevent the conveyor belt 14 from being conveyed in the traveling direction, that is, backward.

At this time, the short root ginseng A is thicker than the distance between the conveyor belt 14 and the foliage drawing roller 15, so that the conveyor belt
Although it is not drawn between 14 and the foliage-drawing roller 15, the residual foliage C of this ginseng A is caused by the backward movement of the upper conveyor path 14a of the conveyor belt 14 and the rotation of the foliage-drawing roller 15. The conveyor belt 14 is drawn between the traveling upper part 14a and the foliage drawing roller 15.

Then, in a state where the residual stem leaf C of the short root ginseng A is pulled by the traveling upper part 14a of the conveyor belt 14 and the leaf drawing roller 15, the short root ginseng A is put into the leaf drawing roller 15
The root ginseng A is transferred to the end of the root and leaf pull-in roller 15 on the side where the root vegetables are carried out, so that the residual stem leaves C of the root ginseng A are transferred from the root to the cutter 22. Be disconnected.

The residual stem leaves C cut from the root part
Is transported to the rear by the conveyor belt 14 and is discharged, and the short root ginseng A from which the residual foliage C has been removed is discharged in the direction of the inclination of the foliage drawing roller 15 and is stored in the container 25.

Therefore, the harvesting work for harvesting the short root ginseng A of the ridge D multi-cultivated with the film F and the peeling of the film F coated on the surface of the ridge D to reach the ridge groove on one side of the ridge D. It is possible to simultaneously perform the elimination work of eliminating by a single work process.

In the above-mentioned embodiment, the case of harvesting the short root ginseng A of the multi-cultivated furrow D was explained, but the present invention is not limited to this. It may be one that harvests other crops such as carrots having foliage B that grows on the film F.
