Abstract

A merger, with a supporting frame having a longitudinal member and crossmembers, with a wheeled chassis, with a drawbar engaging the supporting frame and via which the merger couples to a tractor, with pickup members for picking up crop, wherein one pickup member is accommodated on a first side of the longitudinal member and another pickup member is accommodated on a second side of the longitudinal member, in each case on a crossmember, with belt conveyors for conveying picked-up crop in a transverse conveying direction running transversely with respect to a longitudinal direction, wherein at least one belt conveyor is accommodated on a first side of the longitudinal member and another belt conveyor is accommodated on a second side of the longitudinal member, on the respective crossmember, wherein the drawbar pivots relative to the supporting frame for transferring the merger between a working position to headland or transport position.

First claim

The invention claimed is:

1. A harvesting apparatus, namely merger or pickup swather,
with a supporting frame ( 11 ) having a longitudinal member ( 12 ) and crossmembers ( 13 , 14 ),
with a chassis ( 16 ) having wheels ( 17 ),
with a drawbar ( 15 ) which engages on the supporting frame ( 11 ) and via which the harvesting apparatus can be coupled to a tractor,
with pickup members ( 18 ) designed as a pickup for picking up harvested crop, wherein at least one pickup member ( 18 ) is accommodated on a first side of the longitudinal member ( 12 ) and at least one further pickup member ( 18 ) is accommodated on a second side of the longitudinal member ( 12 ), in each case on a crossmember ( 13 , 14 ),
with transverse conveyor devices ( 19 ) designed as belt conveyors for conveying the picked-up harvested crop in a transverse conveying direction running transversely with respect to a longitudinal direction, wherein at least one transverse conveyor device ( 19 ) is accommodated on a first side of the longitudinal member ( 12 ) and at least one further transverse conveyor device ( 19 ) is accommodated on a second side of the longitudinal member ( 12 ), on the respective crossmember ( 13 , 14 ),
characterized in that
the drawbar ( 15 ) and the chassis ( 16 ) are pivotable relative to the supporting frame ( 11 ) for transferring the harvesting apparatus between a working position and a headland position and/or a transport position; and
an actuator ( 28 ) for the pivoting movement of the chassis ( 16 ) relative to the supporting frame ( 11 ) engages in the region of a longitudinal center axis of the longitudinal member ( 12 ) of the supporting frame ( 11 ) at one end on the longitudinal member ( 12 ) of the supporting frame ( 11 ) and at the other end on the chassis ( 16 ).

2. The harvesting apparatus according to claim 1 , characterized in that the drawbar ( 15 ) engages at a first end ( 15 a ) via a joint ( 22 ) on the supporting frame ( 11 ), wherein the drawbar ( 15 ) is pivotable relative to the supporting frame ( 11 ) about the joint ( 22 ) when the harvesting apparatus is transferred between the working position and the headland position and/or transport position.

3. The harvesting apparatus according to claim 1 , characterized in that a pivot axis ( 23 ) of the drawbar ( 15 ) runs in an approximately horizontal direction perpendicularly to the longitudinal member ( 12 ) of the supporting frame ( 11 ).

4. The harvesting apparatus according to claim 1 , characterized in that at least one actuator ( 25 ) for the pivoting movement of the drawbar ( 15 ) relative to the supporting frame ( 11 ) engages at one end on the supporting frame ( 11 ) and at the other end on the drawbar ( 15 ).

5. The harvesting apparatus according to claim 4 , characterized in that a first actuator ( 25 ) adjacent to a first side of a longitudinal center axis of the longitudinal member ( 12 ) of the supporting frame ( 11 ) and a second actuator ( 25 ) adjacent to a second side of the longitudinal center axis of the longitudinal member ( 12 ) of the supporting frame ( 11 ) engages at one end on the longitudinal member ( 12 ) of the supporting frame ( 11 ) and at the other end on the drawbar ( 15 ).

6. The harvesting apparatus according to claim 1 , characterized in that the drawbar ( 15 ) can be coupled at a second end ( 15 b ) to the harvesting vehicle via a hitch device ( 24 ).

7. The harvesting apparatus according to claim 6 , characterized in that the hitch device ( 24 ) is a lower-link hitch device or a ball-type hitch device.

8. The harvesting apparatus according to claim 1 , characterized in that the chassis ( 16 ) is pivotable relative to the supporting frame ( 11 ) for transferring the harvesting apparatus between the working position and the headland position and/or transport position.

9. The harvesting apparatus according to claim 8 , characterized in that the chassis ( 16 ) engages on the supporting frame ( 22 ) via a joint ( 26 ), wherein the chassis ( 16 ) is pivotable relative to the supporting frame ( 22 ) about the joint ( 26 ) when the harvesting apparatus is transferred between the working position and the headland position and/or transport position.

10. The harvesting apparatus according to claim 8 , characterized in that a pivot axis ( 27 ) of the chassis ( 16 ) runs perpendicularly to the longitudinal member ( 12 ) of the supporting frame ( 11 ).

11. A harvesting apparatus, namely merger or pickup swather,
with a supporting frame ( 11 ) having a longitudinal member ( 12 ) and crossmembers ( 13 , 14 ),
with a chassis ( 16 ) having wheels ( 17 ),
with a drawbar ( 15 ) which engages on the supporting frame ( 11 ) and via which the harvesting apparatus can be coupled to a tractor,
with pickup members ( 18 ) designed as a pickup for picking up harvested crop, wherein at least one pickup member ( 18 ) is accommodated on a first side of the longitudinal member ( 12 ) and at least one further pickup member ( 18 ) is accommodated on a second side of the longitudinal member ( 12 ), in each case on a crossmember ( 13 , 14 ),
with transverse conveyor devices ( 19 ) designed as belt conveyors for conveying the picked-up harvested crop in a transverse conveying direction running transversely with respect to a longitudinal direction, wherein at least one transverse conveyor device ( 19 ) is accommodated on a first side of the longitudinal member ( 12 ) and at least one further transverse conveyor device ( 19 ) is accommodated on a second side of the longitudinal member ( 12 ) on the respective crossmember ( 13 , 14 ),
characterized in that
the drawbar ( 15 ) and the chassis ( 16 ) are pivotable relative to the supporting frame ( 11 ) for transferring the harvesting apparatus between a first position and a second position; and
an actuator ( 28 ) for the pivoting movement of the chassis ( 16 ) relative to the supporting frame ( 11 ) engages at one end on the supporting frame ( 11 ) and at the other end on the chassis ( 16 ).

12. The harvesting apparatus according to claim 11 , characterized in that the actuator ( 28 ) engages in the region of a longitudinal center axis of the longitudinal member ( 12 ) of the supporting frame ( 11 ) at one end on the longitudinal member ( 12 ) of the supporting frame ( 11 ) and at the other end on the chassis ( 16 ).
