Abstract

A round baler is provided having a bale chamber that is partly covered by stationary side walls assuming the size and shape of the bale chamber and by a gate having a skirt which can be brought into an overlapping relationship with the side walls when the gate is closed.

Claims

1. A round baler having a bale chamber covered by at least partially laterally moveable side walls and a bale exit gate, when the gate is opened the side walls are disconnected from the gate, wherein the gate has side structures with a skirt, which follows a part of the circumference of the side walls and which is brought into an overlapping relationship with the side walls when the gate is closed.

2. A round baler according to claim 1, wherein the gate comprises a belt with one of a closed and substantially, closed surface, which extends over the full width of the bale chamber.

3. A round baler according to claim 2, wherein the belt is routed over rolls, the rolls having, a bearing area and wherein at least one bearing area of the rolls is provided with a slot which extends in the side structure radially outwardly.

4. A round baler according to claim 1, wherein at least one of the side walls is of the sheet type, is connected to the frame of the round baler and is moveable towards and away from the sides of the bale chamber.

5. A round baler according to claim 1, wherein a set of side structures are interconnected releasably by way of at least one of braces and the rolls.

6. A round baler according to claim 1 wherein the side structures have a width such that at least one of a retainer for a gate cylinder, a gate lock, a tensioning mechanism for the rolls and an idler can be assumed within the width.

7. A round baler according to claim 1, wherein a gate lock is provided on a freely moveable part of the gate and is formed to receive a counter lock on the frame of the round baler for a solid connection.

8. A round baler according to claim 1, wherein a guide is provided at a portion of the side structure which approaches the side walls of a bale chamber first when the gate moves to a closed position.

9. A round baler according to claim 2, wherein the side structures comprise a roll being located such that it acts on the lateral edge of the endless belt.

10. A round baler according to claim 2, wherein one of the rolls routing the belt is located such that the belt is deflected to the interior of the bale chamber.

11. A round baler according to claim 1, wherein the side structures are composed at least substantially of identical parts.

12. A round baler according to claim 1, wherein a side sheet is provided on the outer side of the side structure.

13. A round baler according to claim 2, wherein a shoulder type path is fastened to the side structure at one end and to the skirt at the other end to provide for an offset of the skirt to the inner surface of the side structure towards the interior of the bale chamber.

14. A round baler according to claim 13, wherein between the downstream end of the path and a subsequent roll a rotatable idler is provided for decreasing the pressure of the belt on the path.

15. A round baler according to claim 13, wherein a roll upstream of the path is driven faster than a roll downstream of the path.

16. A round baler according to claim 2, wherein one part of the bale chamber is covered circumferentially by the belt, whereas another part is covered by bale forming elements being moveable to provide for a bale chamber of varying size.

17. A round baler according to claim 1, wherein the gate in at least one roll bearing area serves also, as gate bearing and has a radially extending slot.
