[0040]
The plurality of guide rods 48a of the carrot lower cutting device 47 are fixed to the upper and lower support rods 49a and 49b on both upper and lower sides at a predetermined interval as shown in FIGS. Reference numerals 49a and 49b are mounted on the receiving plate 19a so as to be movable up and down, and are configured so that the cutting position of the tip of the root of carrot (A) can be adjusted.
The protrusion 49c provided on the cutting blade 48b and shaving off a predetermined position of the tip of the carrot (A) root is provided between the guide rods 48a and 48a.
[0041]
Thereby, by being able to adjust the cutting position of the tip part of the root of the carrot (I), it is possible to set the cutting position according to the shape of the carrot (I), so that it is possible to prevent deep cutting, and in the middle part By providing, the cutting | disconnection performance of a front-end | tip part can be improved.
As shown in FIG. 4, an auxiliary receiving frame 50 on which a spare storage box 15 is placed is provided at the rear right side of the chassis 7 of the traveling vehicle 2 in plan view.
