Abstract

A round baler is provided having a frame, a baling chamber formed on the frame to form a round bale, a discharge region formed between the baling chamber and a base surface, and at least one handling element which is arranged in the discharge region and which extends parallel to the rotation axis of the round bale and serves to support the round bale during the discharge process. To reduce the mechanical load of the round bale, the handling element has an elastic layer which is elastically deformable under the effect of the round bale during the discharge process.

First claim

The invention claimed is:

1. A round baler comprising a frame, a baling chamber adapted to form a round bale having a rotation axis extending traverse to a direction of travel of the baler, the baling chamber being formed on the frame, a discharge ramp between the baling chamber and a ground surface, first and second elongate handling elements arranged on the discharge ramp and extending parallel to the rotation axis of the round bale and being located in a path taken by a falling bale once discharged from the baling chamber so as to be engaged by the falling bale during a discharge process, the first elongate handling element including a rigid profile carrier having an exterior provided with an elastic layer of material which deforms elastically, upon being engaged by the bale, an amount for absorbing sufficient kinetic energy of the discharged bale so as to prevent damage to the bale during the discharge process, the profile carrier shaped so as to define a flat profile on which the elastic layer is formed, the elastic layer covered at least partially by a cover mounted so as to move together with the elastic layer under the influence of a discharged bale engaging the first elongate handling element, the second elongate handling element positioned between the first elongate handling element and an end of the discharge ramp, and the second elongate handling element moving independently of the first elongate handling element.

2. The round baler according to claim 1 , wherein the elastic layer is substantially covered by the cover.

3. The round baler according to claim 1 , wherein the elastic layer is formed from at least one of a foam, an elastomer and another elastic material.

4. The round baler according to claim 1 , wherein the first handling element is positioned in front of the rotation axis of the round bale when the round bale is received.

5. A round baler comprising:
a discharge ramp sloping downward from a position near the baling chamber towards a ground surface, the discharge ramp configured to receive a round bale from the baling chamber and deposit the round bale on the ground surface;
a first handling element positioned on the discharge ramp and extending parallel to the rotation axis of the round bale, first handling element shaped so as to define a flat profile having an elastic layer on an exterior surface contacted by the round bale, the elastic layer surrounded by a protective cover; and
a second handling element positioned on the discharge ramp and extending parallel to the first handling element, the second handling element positioned nearer the ground surface than the first handling element, the second handling element positioned between the first handling element and a discharge end of the discharge ramp, and the second handling element moving independently of the first handling element.

6. The round baler of claim 5 , wherein the first handling element is positioned in front of the rotation axis of the round bale when the round bale is received.

7. The round baler of claim 5 , wherein the first handling element is a flat plate and the second handling element is a roller.

8. The round baler of claim 5 , wherein the first handling element has a rectangular profile and the second handling element is a roller.

9. The round baler of claim 5 , wherein the protective cover is plastic.

10. The round baler of claim 5 , wherein the elastic layer is a foam material.

11. The round baler of claim 5 , wherein the elastic layer is rubber.

12. The round baler of claim 5 , wherein the elastic layer is an elastomer.

13. The round baler of claim 5 , further comprising:
a third handling element positioned on the discharge ramp and extending parallel to the first handling element, the third handling element positioned closer to the ground surface than the second handling element, the third handling element moving independently of the first and second handling elements.
