Foliage-processing device and harvesting machine comprising such a foliage-processing device

1. A foliage-processing device which can be moved across agricultural land in a direction of travel for foliage of tuberous plants growing in rows on agricultural land, the foliage-processing device comprising:

a foliage puller which is provided with at least two mutually oppositely rotating rollers between which foliage can be clamped and pulled off; and

guide baffles configured to guide foliage to a conveyor belt wherein the foliage pulled off by the foliage puller is removed next to a row or between the rows of tuberous plants growing on the agricultural land via the conveyor belt.

2. The foliage-processing device according to claim 1 , wherein the conveyor belt is arranged behind the foliage puller, at a distance therefrom.

3. The foliage-processing device according to claim 1 , wherein the foliage-processing device further includes a guide mechanism arranged near the rollers of the foliage puller, the guide mechanism assisting in moving the pulled-off foliage via the rollers back to the agricultural land for further processing by the foliage-processing device.

4. The foliage-processing device according to claim 3 , wherein the guide mechanism comprises a guide roller, the rotation axle of which extends along the width of the foliage-processing device.

5. The foliage-processing device according to claim 1 , wherein the rollers of the foliage puller are conical and partly elastic, each of the conical rollers has ends with varying diameters, wherein the ends of the conical rollers with a smallest diameter form the foremost part of the foliage-processing device.

6. The foliage-processing device according to claim 1 , wherein the rotation axles of the rollers extend substantially in the direction of travel, wherein the rotation axles of the rollers enclose an acute angle with the horizontal.

7. The foliage-processing device according to claim 1 further including a haulm topper with a rotation axle extending in the width direction of the foliage-processing device, the haulm topper extending virtually across the width of the foliage-processing device.

8. The foliage-processing device according to claim 1 , wherein the foliage-processing device comprises two oppositely rotatable transport rollers which are arranged above the rollers of the foliage puller, wherein each transport roller has the same direction of rotation as the roller of the foliage puller situated underneath.

9. The foliage-processing device according to claim 8 , wherein the foliage-processing device is provided with guide baffles which are situated at least partly around the transport rollers to remove the pulled-off foliage to a position next to a row or to a position between the rows of tuberous plants growing on the agricultural land.

10. The foliage-processing device according to claim 1 , wherein more than one row of the tuberous plants growing on the agricultural land can be treated simultaneously by means of the foliage-processing device.

11. A harvesting machine comprising a foliage-processing device according to claim 1 .

12. The harvesting machine according to claim 11 , wherein the harvesting machine is self-propelled.

13. A foliage-processing device that can be moved across agricultural land in a direction of travel for foliage of tuberous plants growing in rows on the agricultural land, the foliage-processing device comprising:

a foliage puller including at least two mutually oppositely rotating rollers between which foliage can be clamped and pulled off;

a foliage-processing mechanism configured to remove the pulled off foliage from the foliage puller, the foliage being removed next to a row or between the rows of tuberous plants growing on the agricultural land; and

a guide roller arranged near the oppositely rotating rollers of the foliage puller, the guide roller assisting in moving the pulled-off foliage via the oppositely rotating rollers back to the agricultural land for further processing by the foliage-processing device, a rotation axle of the guide roller extending along a width of the foliage-processing device.

14. The foliage-processing device according to claim 13 , wherein the rollers of the foliage puller are conical and partly elastic, each of the conical rollers has ends with varying diameters, wherein the ends of the conical rollers with a smallest diameter form the foremost part of the foliage-processing device.

15. The foliage-processing device according to claim 13 , wherein the rotation axles of the oppositely rotating rollers extend substantially in the direction of travel, the rotation axles of the rollers enclosing an acute angle with the horizontal.

16. The foliage-processing device according to claim 13 , wherein the foliage-processing mechanism further performs a mechanical foliage-destroying operation by using at least one blade.

17. A foliage-processing device that can be moved across agricultural land in a direction of travel for foliage of tuberous plants growing in rows on the agricultural land, the foliage-processing device comprising:

a foliage puller including at least two mutually oppositely rotating rollers between which foliage can be clamped and pulled off;

a foliage-processing mechanism configured to remove the pulled off foliage from the foliage puller, the foliage being removed next to a row or between the rows of tuberous plants growing on the agricultural land; and

a haulm topper with a rotation axle extending in a width direction of the foliage-processing device, the haulm topper extending virtually across the width direction of the foliage-processing device.
