In such a case, the pair of first guide bars 47 described above contact the root portion Ca of the carrot C so that the root portion Ca of the carrot can be housed within the width of the two rotating disks 8a and 8b. It has a function to correct the posture.

Similarly, in FIGS. 5 and 13, in a side view, a state in which the pair of first guide bars 47 and the two rotating disks 8a and 8b intersect is inclined obliquely upwardly from the intersection. Thus, a pair of second guide bars 48 are arranged above the two rotating disks 8a, 8b with a predetermined interval. The width of the pair of second guide bars 48 is slightly narrower than the root Ca of the carrot C, and from the portion on the front side from immediately above the rotation center S ₂ of the _two rotary disks 8a and 8b, Up to the portion immediately above, it has a function of sliding the boundary portion between the root portion Ca and the leaf portion Cb of the carrot C in the course of rotary conveyance to erect the root portion Ca of the carrot C in a posture tilted backward. That is, since the distance between the peripheral portions of the two rotating disks 8a and 8b and the pair of second guide bars 48 increases as the disks 8a and 8b rotate, the pair of second guide bars 48 is formed. The root portion Ca of the carrot C sliding on the upper surface of the carrot C is pulled by the rotation of the disks 8a and 8b toward the peripheral edge thereof, so that the root portion Ca is gradually erected and corrected to an inverted posture. It

FIG. 17 is also a partial side view, FIG. 17 is a rear view of the driving force transmission mechanism T of the portion of the self-propelled carriage device A, and FIG. 18 is an eccentric shaft for driving the lower link 34 of the soil loosening device J. It is a figure which shows 33. The power of the output shaft 53 of the engine E mounted on the carriage 1 is transmitted to the counter shaft 54 arranged in the front-rear direction inside the carriage 1 by belt transmission. The power transmitted to the counter shaft 54 is also transmitted to the input shaft 56 of the traveling mission 55 and the first shaft by the belt transmission.
It is transmitted to the input shaft 58 of the bevel gear transmission 57. The power transmitted to the traveling mission 55 is output from the first and second output shafts 59 and 61. First
The drive shaft 62 of each rubber crawler 2 is directly connected to the output shaft 59, and the drive sprocket 5 is driven and rotated. The power transmitted to the second output shaft 61 is transmitted to the rotary shaft 63 supported inside the hollow shaft 11a by belt transmission. Since the rotating shaft 63 and the input shaft 12a of the first worm speed reduction mission 12 are connected via the coupling 64, the second output shaft 6 of the traveling mission 55 is connected.
Power is transmitted from 1 to each drive unit of the harvesting machine B. Further, the power of the first output shaft 65 of the first bevel gear transmission 57 is transmitted to the eccentric shaft 33 for driving the lower link 34 of the soil loosening device J by belt transmission, and

Since the driving force transmission mechanism T drives both the self-propelled carriage device A and the harvesting work machine B by the power of the engine E, the traveling of the self-propelled carriage device A and the harvesting work machine B are performed. The rotations of the two rotating disks 8a and 8b that are formed are synchronized with each other. Therefore, the traveling speed V ₁ of the self-propelled carriage device A and the two rotary disks 8a, 8 of the harvesting work machine B are set.
The ratio of b to the rotation speed V ₂ is always constant. Further, each of the driving force transmission mechanisms T on the side of the self-propelled carriage device A is housed under the base plate 7 of the carriage 1, and the upper surface of the base plate 7 holds the container 76 containing the harvested carrot C. It is a container mounting surface 77 for mounting.

The portion Cb is raised (see FIG. 20), and the leaf portion Cb is inserted between the pair of guide plates G that follow in this raised posture, so that the raised posture is maintained (FIG. 21). Also,
A vibrating blade 38 is arranged at a position corresponding to the front end portions of the pair of guide plates G, and the vibrating blade 38 enters a portion deeper than the root portion Ca of the carrot C in the soil, and the ginger carrot is vibrated by the vibrating action of the vibrating blade 38. The soil around the root Ca of the plant is softened (Fig. 2
1).

Since the harvesting machine B is moving forward, the leaf portion Cb of the carrot C kept in the raised state by the pair of guide plates G has two rotating discs 8a,
As shown in FIG. 22, the relative position of the carrot C with respect to the rotating disks 8a and 8b sequentially moves to the lowermost part of the rotating disks 8a and 8b as the harvesting machine B advances. As shown, the leaf part C of the carrot C
b is clamped by the elastic clamping members 18 on the outer peripheral edges of the two rotary disks 8a and 8b.
Since the a and 8b proceed while rotating further, the carrot C is pulled out from the soil. In this way, the carrot C extracted from the soil has two rotating disks 8a and 8b.
