Then, the leaf portion Wb is nipped by the left and right conveyor belt front side portions 11a with a strong nipping force and lifted rearward and upward, so that the root vegetables W are pulled up from the field, and subsequently, the belt intermediate portion 11b in the nipping and lifting conveyance device 9 The sheet is further conveyed rearward and upward by the belt rear half portion 11c and the alignment device 12.

At this time, since the distance between the nipping / pulling-up transporting device 9 and the positioning device 12 is gradually increased toward the lower side of the transporting, the root vegetable main body Wa that is suspended and transported gradually approaches the lower surface of the positioning device 12. Then, the upper surface of the root vegetable main body Wa is brought into contact with the roller 14 as the ascending position regulating guide section. After that, the rearward conveying force is transmitted to the root vegetables W while the rear conveying force is transmitted to the root vegetables W due to the weak gripping force of the belt rear half portion 11b in the gripping pulling and transporting device 9.
Is allowed to move downward relative to
At the end of the conveyor belt 11, the root vegetable body Wa is
And the heights are aligned. Then, the leaf portion Wb is nipped by the leaf nipping nipping and conveying device 22 and supplied to the leaf nipping device 3 as it is.

The root vegetables W supplied to the leaf cutting device 3 are left and right in a state where the leaf portion Wb is securely pinched without moving by the leaf cutting and holding device 22 at a position away from the root vegetable main body Wa. It is cut by the cutters 20, 21.

The cut and separated leaf portion Wb is discharged from the end of the leaf cutting and holding device 21 onto a discharge chute 27 as a leaf portion discharge device, and is dropped and discharged from a predetermined position at the rear of the machine toward a field. In addition, the root vegetable body Wa
Is transported downward by the guide plate 25 in the lateral direction opposite to the side where the root vegetable processing section A is disposed, and is sent to the last container 24a in the collection section D.

Here, a mounting portion for arranging a plurality of containers 24 in front and rear is provided in front of the container 24a for receiving the transferred root vegetable main body Wa. Or an empty container can be arranged on the front mounting portion and replaced with a full container.

In the claims, reference numerals are provided for convenience of comparison with the drawings, but the present invention is not limited to the configuration of the attached drawings by the entry.
