The transfer belts 42c of the tapping transfer devices 34 and the transfer belts 43c from the middle thereof are also taken over by the transfer belts 42c, and are transported while being pinched by both. Also, from the rear side of the leaf cutting device 12 that is trailing, the leaf cutting device 1
In this configuration, the cut leaves cut in Step 2 are pinched and transferred, and dropped and discharged into the field from the transfer end portions of both.

As shown in FIGS. 7 and 9, the leaf cutting device 12 is provided on both the left and right sides below each of the tapping transfer devices 34 at the rear side of each of the head alignment transfer devices 33. Each rotatable rotation shaft 46 is provided so as to protrude downward from each transmission mechanism 38b provided in each upper transmission case 38a of each upper transmission device 38, and a lower end of each rotation shaft 46 is provided with a support metal 45. The left and right disk-shaped cutting blades 44, 44 are bolted to the upper surface of each support metal 45.
And a nut.

The outer diameters of the left and right cutting blades 44, 44 are vertically overlapped by a predetermined dimension, and the gap between the upper and lower sides is configured to be close to the minimum gap of zero. Then, each tapping transfer device 34 and each leaf transfer device 35
And the upper part of the root of the ginseng (a) to be nipped and transported is cut off from the upper part of the root by a predetermined size.
The carrots (A) whose leaves have been cut are the lower first conveyor 1
3 and is transferred by the first transfer conveyor 13 and the second transfer conveyor 14 to be supplied into the storage box 15 mounted on the box mounting table 15a and temporarily stored. .

The ginseng lower part cutting device 47 includes a digging device 5
The ginseng lower part cutting device 47 is provided with a plurality of guide rods 48a having a mountain shape at two upper and lower portions at predetermined intervals on the left and right sides. Within the shape, each rotating tool 48c having a plurality of cutting blades 48b mounted on the outer periphery of the rotation is rotatably and pivotally supported at predetermined intervals vertically.

The ginseng undercutting device 47 is sandwiched between the transfer belts 28a of the transfer devices 28, and the top of the root portion of the short ginseng (a) having a short chevron during transfer to the upper portion has a lower chevron shape. It enters between the guide rods 48a, 48a, and the lower cutting blade 48b cuts a predetermined position of the tip of the root of the ginseng (a). Ginseng with a long length during transfer to the top (a)
Passes through the lower chevron guide rod 48a, and between the upper chevron guide rods 48a, 48a, the tip of the root of the ginseng (a) enters. It is cut by the blade 48b. A predetermined position at the tip of the root of the ginseng (a) is cut by the total length of the root of the ginseng (a).
