[Effect] The invention works as follows.

In the present application, the roots of the carrot 18 are pulled out while holding the stems and leaves 18A with a belt, and the stems and leaves are transferred to the rear, and the stems and leaves are cut and removed at a predetermined position with a rotary blade.

In this case, a gauge wheel at the front of the machine determines where to pinch the leaves, but before doing so, a chisel is used to cut into the soil between the furrows to soften the soil around the roots and reduce pulling resistance.

As a result, the foliage is held between the front pulleys 3 and 4, and at the same time, the roots are easily pulled out, and the foliage is held between the V-belts and conveyed rearward.

During this rearward conveyance, the rotary blade cuts off the foliage at the upper surface of the lower V-belts 8, 10, and the remaining lower foliage is moved rearward while being held between the lower V-belts 8, 10. Become.

In this case, in the second invention, the lower V belts 8, 10
Since a stronger tension is applied to the upper V-belts 7 and 9 than to the upper V-belts 7 and 9, when the carrot comes near the rotary blade, the back of the carrot is drawn to the lower surface of the lower V-belts 8 and 10 and comes into contact with it.

Therefore, the extraction work can be carried out efficiently and quickly without having to work in an unnatural posture as in the past.

B After pulling it out, when conveying it to the rear, the rotary blade cuts off the stems and leaves at the upper surface of the lower V-belts 8 and 10, and the remaining lower stems and leaves are carried backward while being held between the lower V-belts 8 and 10. It can be moved.

This eliminates the need to pick up each vine one by one and cut out the foliage with a knife, as in the past, and the foliage can be separated from the upper V-belt, and the remaining lower foliage can be separated by the lower belt. Since they are transported, it is easy to separate them.

C. In addition, in the second invention, strong and weak tensions are added as described above, so that the following effects occur.

That is, since a stronger tension is applied to the upper V-belts 7 and 9 than to the lower V-belts 8 and 10, when the carrot comes near the rotating blade,
The shoulder portion of the carrot is drawn to and comes into contact with the lower surface of the lower V-belts 8, 10.

As a result, the cutting parts of the stems and leaves are always aligned, and since the tension of the lower V-belts 8, 10 is strengthened after cutting, the leaves are further conveyed rearward while being held.

In this way, the device of the present application can pull out the roots of carrots while holding them between the belts, transfer them to the rear, and then cut and remove the stems and leaves at a specified position with a rotary blade, which eliminates the conventional work described above. Compared to,
This allows for even more labor-saving work, reducing worker fatigue and shortening harvest time.
