Abstract

A transport device for an agricultural utility machine is provided, having a first pipe section in which a first conveyor auger is rotatably situated and a second pipe section in which a second conveyor auger is rotatably situated, and a joint and/or plug device to connect the first pipe section to the second pipe section. A friction clutch is provided between the first and the second conveyor auger to transfer torque from the first conveyor auger to the second conveyor auger. An agricultural utility machine having such a transport device is also provided.

Claims (13)

1. A transport device for an agricultural utility machine, comprising a first pipe section in which a first conveyor auger is rotatably situated and a second pipe section in which a second conveyor auger is rotatably situated, and at least one of a joint or plug device that connects the first pipe section to the second pipe section, and a friction clutch is provided between the first and second conveyor augers to transfer torque from the first conveyor auger to the second conveyor auger.

2. The transport device according to claim 1 , wherein the friction clutch is provided in an area of the at least one of the joint or plug device.

3. An agricultural utility machine comprising a storage container for bulk goods, and a transport device according to claim 1 connected to the storage container.

4. The agricultural utility machine of claim 3 , wherein the agricultural utility machine comprises a combine harvester.

5. A transport device for an agricultural utility machine, comprising a first pipe section in which a first conveyor auger is rotatably situated and a second pipe section in which a second conveyor auger is rotatably situated, and at least one of a joint or plug device that connects the first pipe section to the second pipe section, and a friction clutch is provided between the first and second conveyor augers to transfer torque from the first conveyor auger to the second conveyor auger, wherein an opposing pressure plate of the friction clutch is connected to the first conveyor auger in a rotationally fixed connection, and a pressure plate of the friction clutch that is limitedly movable in axial direction is connected to the second conveyor auger in a rotationally fixed connection.

6. The transport device according to claim 5 , wherein a plurality of coupling elements are provided between the pressure plate and the second conveyor auger, the coupling elements are distributed in a circumferential direction and provide for limited movement in an axial direction and for rotationally fixed connection of the pressure plate to the second conveyor auger.

7. The transport device according to claim 6 , wherein the coupling elements are bolts or leaf springs.

8. The transport device according to claim 6 , wherein at least one of the opposing pressure plate or the pressure plate have in a radially outer area thereof a housing section, which forms a clutch plate housing to receive a clutch plate when the first pipe section is connected to the second pipe section.

9. The transport device according to claim 8 , wherein the clutch plate of the friction clutch is connected to the first conveyor auger or to the second conveyor auger in a rotationally fixed connection.

10. A transport device for an agricultural utility machine, comprising a first pipe section in which a first conveyor auger is rotatably situated and a second pipe section in which a second conveyor auger is rotatably situated, and at least one of a joint or plug device that connects the first pipe section to the second pipe section, a friction clutch is provided between the first and second conveyor augers to transfer torque from the first conveyor auger to the second conveyor auger, wherein a single- or multiple-part clutch cover of the friction clutch is connected to at least one of the first or the second conveyor auger in a rotationally fixed connection.

11. The transport device according to claim 10 , wherein an energy storage device is provided in an axial direction between the clutch cover and a pressure plate of the friction clutch.

12. The transport device according to claim 11 , wherein the energy storage device comprises a diaphragm spring or leaf spring.

13. The transport device according to claim 11 , wherein the energy storage device is pre-tensioned when the first pipe section is connected to the second pipe section, and to shift the pressure plate in the axial direction to clamp a clutch plate frictionally between the pressure plate and an opposing pressure plate.
