Abstract

A root crop conveyor is provided for cleaning and/or separating root crops, including at least two adjacent roller groups, each of which have at least two rollers, which each rotate about an axis of rotation and of which the axes of rotation form a roller group plane. An adjusting device is provided with at least one adjusting means. At least the rollers of at least one roller group are mounted, on one side, in at least one side part which interacts with the adjusting means, such that actuation of the adjusting means can give rise to movement of the at least one roller group plane relative to a frame in which the root crop conveyor can be arranged. wherein the adjusting device pivots the roller group plane. The rollers of a roller group are connected to one another via a scissors mechanism.

Claims (20)

1. A root crop conveyor for cleaning and/or separating root crops, the conveyor comprising:

at least two adjacent roller groups, each of which have at least two rollers, which each rotate about a respective axis of rotation and of which the axes of rotation form a roller group plane,

an adjusting device, which is provided with at least one adjusting means,

wherein at least the rollers of at least one roller group are mounted, on one side, in at least one side part which interacts with the at least one adjusting means, such that actuation of the adjusting means can give rise to movement of the roller group plane relative to a frame in which the root crop conveyor can be arranged,

wherein the adjusting device pivots the roller group plane,

wherein the rollers of each of the at least two adjacent roller groups are connected to one another via a scissors mechanism.

2. The root crop conveyor as claimed in claim 1 , wherein the adjusting means pivots at least one of the roller group planes.

3. The root crop conveyor as claimed in claim 2 , wherein the adjusting device has at least two adjusting means which are provided for one side of the root crop conveyor, wherein a first of the adjusting means, which is provided for pivoting purposes, can be actuated independently of a second of the adjusting means.

4. The root crop conveyor as claimed in claim 3 , wherein the at least two adjusting means are articulated on a common link, which connects two roller groups.

5. The root crop conveyor as claimed in claim 3 , further including third adjusting means, which can adjust an inclination of the root crop conveyor as a whole.

6. The root crop conveyor as claimed in claim 1 , wherein the two adjacent roller groups are coupled to one another by a joint in the form of at least a four bar linkage, and by way of the adjusting means, which is provided for pivoting purposes, at least one bearing point of a roller group can be height adjusted in relation to an adjacent bearing point, as seen in a side view.

7. The root crop conveyor as claimed in claim 6 , wherein two adjacent roller groups are connected to one another in the manner of a parallelogram.

8. The root crop conveyor as claimed in claim 1 , wherein the side parts of the scissors mechanism are mounted, on both sides of the rollers, in respectively two coupling rods each with slots.

9. The root crop conveyor as claimed in claim 1 , wherein all the rollers of a roller group are mounted, on one side, in just one side part.

10. The root crop conveyor as claimed in claim 1 , further including an eccentric suspension arrangement at least for one roller group.

11. A piece of agricultural equipment used for storage purposes, characterized by a root crop conveyor as claimed in claim 1 .

12. The root crop conveyor as claimed in claim 1 , wherein the adjusting device pivots the roller group plane in relation to an axis of rotation of a roller of an adjacent roller group.

13. The root crop conveyor as claimed in claim 4 , wherein the adjusting means are not secured on the frame.

14. The root crop conveyor as claimed in claim 6 , wherein the adjusting means, which is provided for pivoting purposes, acts on a connecting link, which connects two roller groups.

15. The root crop conveyor as claimed in claim 10 , wherein the adjusting means is in drive connection with a disk of the eccentric suspension arrangement.
