The tail cutting blade 124 cuts the carrot tail at a position above the cutting tool drive shaft 125. The first tail cutting tool 120 and the second tail cutting tool 121 are 90 degrees out of phase with each other so that the first tail cutting tool 120 and the second tail cutting tool 121 do not cut simultaneously. Thus, the drive resistance of the cutting tool drive shaft 125 is prevented from locally increasing. A safety guard 127 in which a plurality of slits 127a extending in the front-rear direction are arranged on the left and right sides is provided at least on the outer peripheral portion of each of the first tail cutting tool 120 and the second tail cutting tool 121. The carrot tail enters the safety guard 127 through the slit 127 a and is cut by the first tail cutting tool 120 or the second tail cutting tool 121. The sorting guide 122 is configured in a sloped shape that becomes rearward as it goes to the right side so as to guide it from the conveyance center line of the drawing conveyance path R to the front of the second tail cutting tool 121. There is a sorting guide 123 at the position of the second tail cutting tool 121 side (right end, rear end) of the sorting guide 122 in plan view of the machine body. The sorting guide 123 is higher than the sorting guide 122 and is held between the left and right. The belt 18 is disposed at a high position (a position close to the conveyance locus) with respect to the conveyance locus that is inclined rearward. The sorting guide 123 and the sorting guide 122 are disposed below the left and right nipping and conveying belt 18.

  Therefore, the carrots that pass through the soil removal brushes 39 and 39 and are transported obliquely rearward and upward in the drawing transport path R are first sorted into long and short by the sorting guide 122. That is, the long carrot is conveyed while the lower part is in contact with the distribution guide 122, and is guided to the second tail cutting tool 121 side by the distribution guide 122. Short ginseng is conveyed while the lower part does not contact the distribution guide 122 or with very small contact force, so that it passes over the distribution guide 122 on the conveyance center line of the drawing conveyance path R and is conveyed to the rear side. And supplied to the first tail cutting tool 120. The carrots distributed left and right by the distribution guide 122 are reliably sorted by the sorting guide 123 and supplied to the first tail cutting tool 120 or the second tail cutting tool 121. The long ginseng is cut by the small-diameter second-tail cutting tool 121, and the short ginseng is cut by the large-diameter first tail-cutting tool 120. Therefore, the tail is cut at an appropriate position corresponding to the length of the carrot. Can be cut. In addition, the second tail cutting tool 121 is disposed below the line (see FIG. 6) passing through the upper end of the sorting guide 122 and parallel to the rearward rising slope of the left and right holding and conveying belt 18 in a side view of the machine body. The tail cutting blade 124 of the single tail cutting tool 120 is disposed at a position protruding above the line by the rotation of the first tail cutting tool 120. In addition, the long carrot which passed the 2nd tail part cutting tool 121 returns to the conveyance centerline of the drawing conveyance path | route R again before the branch body 128 mentioned later by conveyance of the right-and-left pinching conveyance belt 18. FIG. Therefore, since the short ginseng is transported on the transport center line of the pulling transport path R even at the position where the tail cutting device 43 acts, the transport trouble such as the short carrot falling off the left and right nipping transport belt 18 or the transport posture deteriorates. Can be conveyed accurately.

  The conventional tail cutting device has a configuration in which a single tail cutting tool is provided on the drawing conveyance path, and cuts the tail at a predetermined position regardless of the length of the carrot. It is conceivable that inconveniences arise such that the lower part is excised or the tail part cannot be cut properly with a short carrot. In addition, for example, when a short ginseng is supplied after a long ginseng, the conventional tail cutting device appropriately cuts the tail of the short ginseng because the cutting action force is taken away by the long ginseng. Difficult inconvenience can be considered.

  In the above description, the first tail cutting tool 120 and the second tail cutting tool 121 are configured to rotate, and the first tail cutting tool 120 has a large diameter and the second tail cutting tool 121 has a small diameter. 120 and the second tail cutting tool 121 are configured to be cut along a linear movement locus, and the first tail cutting tool 120 is located above the second tail cutting tool 121 with respect to the conveyance locus of the rearwardly inclined inclination of the left and right holding conveyance belt 18.

  Further, a spacer 48 thicker than the plate thickness of the first cutting blade 46o and the second cutting blade 46i is mounted below the second cutting blade 46i and below the drive shaft 28 of the first cutting blade 46o. The ginseng edible portion before cutting is elastically deformed by being contacted from the side, and the ginseng after cutting is orthogonal to the conveying direction of the foliage sandwiching and conveying devices 45i and 45o by elastic restoring force. A push-out disk 49 is attached to the remaining leaf processing conveyor 57, which will be described later, and dropped in a state where the shoulder portion of the carrot is directed to the inner side of the body where the remaining leaf processing roller 56 is disposed. The extrusion disk 49 is formed of an elastic body that is easily deformed and has strong elastic force, such as rubber, and is configured to rotate together with the first cutting blade 46o. The spacer 48 has an outer diameter that does not contact the largest diameter carrot.

Note that the spacer 48 may be a disk blade.
Further, if the extruded disk 49 has substantially the same diameter as the first cutting blade 46o or a slightly larger diameter than the first cutting blade 46o, the extruded disk 49 can easily come into contact with the ginseng shoulder, and the ginseng shoulder becomes the fuselage. It is possible to make the posture facing inward, and the remaining leaf processing conveyor 57 reliably processes the leaf and leaf portion remaining on the root portion, so that it is not necessary to remove this leaf and leaf portion in a subsequent process, and the work efficiency is improved.

  Further, as shown in FIG. 23, the extrusion disk 49 is eccentrically attached inside the outer circumference of the first rotary blade 46o, and is prevented from rotating in synchronization with the ginseng planting interval. To be distributed.

Further, as shown in FIG. 24, the outer periphery of the extrusion disk 49 is partially made uneven so that large and small carrots can be easily skipped.
Furthermore, the extrusion disk 49 may be formed in a dish shape with the outer peripheral edge facing downward, or may be softened by providing a slit on the outer peripheral edge.

The extrusion disk 49 can be removed as appropriate.
Since the average thickness of the first cutting blade 46o and the second cutting blade 46i is about 1 mm, the thickness of the spacer 48 is about 2 mm, so that the first cutting blade 46o and the second cutting blade 46i are formed on the extrusion disk 49. It becomes difficult to entrain.

  As shown in FIG. 18, the first rotary blade 46o and the second rotary blade 46i are attached to the drive shaft 28.

  In the illustrated example, by taking the latter configuration, when adjusting the cutting height of the first rotary blade 46o and the second rotary blade 46i, it is not necessary to release the rotation restricting means, and resistance to the rotation restricting means is reduced. Accordingly, the adjustment can be performed simply by rotating the adjustment knob 82 with respect to the drive shaft 28, and the adjustment operation can be performed very easily. Further, when the fixing of the first rotary blade 46o (second rotary blade 46i) to the mounting member 81 is released (screwing is removed in the illustrated example), the first rotary blade 46o and the second rotary blade 46i are moved to the rotation center side. The size of the hole and the size of the adjustment knob 82 are set so that the formed hole can pass through the adjustment knob 82. Accordingly, the first rotary blade 46o (second rotary blade 46i) can be removed without removing the adjustment knob 82, and the rotary blade can be easily replaced.

  FIG. 19 shows another example of the vertical movement fixing means for the first rotary blade 46o and the second rotary blade 46i. An attachment member 81 is inserted into a rotation preventing prismatic portion 28a formed at the lower portion of the drive shaft 28 so as to be movable only in the axial direction, and the first rotary blade 46o (second rotary blade 46i) is fixed to the attachment member 81.
