Then, the turntable 19 makes one rotation around the output shaft portion 18 and reciprocates the cutting blade support arm 21 via the crank arm 25 so that the cutting blade 5 is being conveyed by the screw auger 2 from the side of the screw auger 2. The rhizome part 1b is cut from the head part 1a of the cabbage 1. In this embodiment, the time lag from when the contact terminal 7 detects the rhizome 1b until the cutting blade 5 cuts the rhizome 1b is one pitch of the conveying position of the screw auger 2.
[0021]
When the cutting blade drive unit 6 is in the operating state, the cam arm 20 is pressed by the pressing cam by the rotation of the rotating disk 19, and the shaft 12 of the linkage lever 12a is pushed up as shown in FIG. The one-turn clutch starting lever 17 is separated and the linkage state is released, and the one-turn clutch starting lever 17 does not activate the cutting blade driving unit 6. Then, in a state where the linkage between the contact terminal 7 and the cutting blade drive unit 6 is released, the contact terminal 7 is moved by the first biasing spring 13 at a stage where the rhizome part 1 b is conveyed to a position where it does not contact the contact terminal 7. At the same time, the linkage lever 12a is returned to the position where it can be linked with the one-rotation clutch starting lever 17 by the second biasing spring 14, and the contact terminal 7 and the cutting blade drive unit 6 can be linked. Return to.
[0022]
On the other hand, the top portion of the head portion 1a of the cabbage 1 conveyed by the screw auger 2 is in contact with the pressing belt 26 and moves the pressing belt 26 up and down, and this vertical movement is caused by the cutting blade through the linkage link 28 and the link rod 29. The vertical height of the cutting blade 5 which is transmitted to the support arm 21 and reciprocates by the power from the cutting blade drive unit 6 from the side of the screw auger 2 is adjusted. Therefore, the cutting blade 5 reciprocates the cutting blade support arm 21 by the cutting blade drive unit 6 in synchronization with the contact terminal 7 detecting the rhizome portion 1 b, and is conveyed by the screw auger 2 from the side of the screw auger 2. When cutting the rhizome part 1b from the head part 1a of the cabbage 1 in the inside, the vertical height of the cutting blade 5 is automatically adjusted according to the height of the head part 1a, and the root part 1b is brought into an appropriate state from the head part 1a. Disconnect. In addition, when the nipping and conveying belt 30 that nipped and conveys the head portion 1a conveyed by the screw auger 2 from both left and right sides is provided, the rhizome portion 1b can be more stably cut.

When the head portion 1a is conveyed in the forwardly tilted state by the screw auger 2 as shown in (b), the center position C of the cutting blade 5 is biased to the front side of the head portion 1a, and the rhizome portion is formed in the latter half of the cutting blade 5 Although 1b is cut | disconnected, since the cutting blade 5 is circular shaped, the rhizome part 1b is cut | disconnected without trouble. When the head part 1 a is conveyed in a backward-tilted state by the screw auger 2 as shown in (c), the center position C of the cutting blade 5 is biased to the rear side of the head part 1 a, and the rhizome is formed in the first half part of the cutting blade 5. Although the part 1b is cut | disconnected, since the cutting blade 5 is circular shape, the rhizome part 1b is cut | disconnected without trouble.
[0024]
The second embodiment of the present invention shown in FIG. 5 is obtained by changing the support structure of the cutting blade 5 compared to the first embodiment. The cutting blade support arm 21 and the vertical axis 22 of the first embodiment are shown in FIG. Instead of the horizontal shaft 23, it comprises a lower support link 31 and an upper support link 32 that bend and stretch in the front-rear direction. A cutting blade 5 is attached to the upper end of the upper support link 32, and the tip of the crank arm 25 is located behind the cutting blade 5 The front end portion of the link rod 29 a is pivotally supported on the side portion of the lower support link 31.
[0025]
