Abstract

An agricultural harvesting machine includes a working assembly for processing a crop flow and a discharge accelerator for the processed crop that is designed as a unit to be installed in its entirety into an operating position (P B ) downstream of the working assembly in the flow path of the crop stream. The discharge accelerator unit is readily deinstalled from the operating position (P B ).

First claim

What is claimed is:

1. An agricultural harvesting machine, comprising:
at least one working assembly ( 2 , 3 ) for processing a crop stream;
a discharge accelerator ( 4 ) for the processed crop configured to be installed in entirety in an operating position (P B ) downstream of the at least one working assembly ( 2 , 3 ) in a flow path of the crop stream and, to be removable from the operating position (P B );
a conveyor chute ( 12 ); and
means for moving the discharge accelerator ( 4 ) out of the operating position (P B ) into an access position (P Z ) within a maintenance space ( 5 ) of the harvesting machine ( 1 );
wherein the means for moving comprises a pivotable support of the discharge accelerator ( 4 ) with respect to a machine frame ( 9 ) in a form of a cab carrier ( 10 ) of the harvesting machine ( 1 );
wherein the discharge accelerator ( 4 ) comprises at least one accelerating mechanism ( 20 ) and an enclosing housing ( 21 ), wherein the accelerating mechanism ( 20 ) is rotatably supported by a shaft ( 8 ) extending in parallel to a front axis of the agricultural harvesting machine; and
wherein the conveyor chute ( 12 ) adjoins the discharge accelerator ( 4 ).

2. The agricultural harvesting machine according to claim 1 , wherein the discharge accelerator ( 4 ) is supported with respect to the machine frame ( 9 ) in a manner rotatable about a pivot axis ( 11 ), in order to be swivellable out of the operating position (P B ) into the access position (P Z ).

3. The agricultural harvesting machine according to claim 2 , wherein a frame-mounted conveyor chute ( 12 ) of the harvesting machine ( 1 ), which is fixedly mounted to the machine frame ( 9 ), adjoins the discharge accelerator ( 4 ) at the top.

4. The agricultural harvesting machine according to claim 1 , wherein at least one rotatable drive wheel ( 14 ), driven wheel ( 15 ) or both is assigned to the discharge accelerator ( 4 ), which, in the operating position (P B ) of the discharge accelerator ( 4 ), is operatively connected to a main drive belt ( 7 ), and wherein the operable connection to the main drive belt ( 7 ) is interrupted in an access position (P Z ) of the discharge accelerator ( 4 ).

5. The agricultural harvesting machine according to claim 4 , wherein the at least one drive wheel ( 14 ) is supported on a shaft ( 8 ) parallel to a pivot axis ( 11 ) of the discharge accelerator ( 4 ) and wherein the shaft is disposed at a distance from the pivot axis ( 11 ).

6. The agricultural harvesting machine according to claim 4 , wherein in the operating position (P B ), the drive wheel ( 14 ) of the discharge accelerator ( 4 ) has a drive connection to the main drive belt ( 7 ) of the harvesting machine ( 1 ), in order to be driven thereby.

7. The agricultural harvesting machine according to claim 4 , wherein in the operating position (P B ), the driven wheel ( 15 ) of the discharge accelerator ( 4 ) has a drive connection to an auxiliary drive belt of the harvesting machine ( 1 ), in order to thereby drive at least one further working assembly ( 3 ).

8. The agricultural harvesting machine according to claim 1 , further comprising a transport device ( 13 ), wherein the transport device ( 13 ) is brought into the maintenance space ( 5 ) in order to lift the discharge accelerator ( 4 ), which has been moved into the access position (P Z ).

9. The agricultural harvesting machine according to claim 1 , wherein the means for moving the discharge accelerator ( 4 ) moves the discharge accelerator ( 4 ) out of the access position (P Z ) into a maintenance position (P W ) outside of the maintenance space ( 5 ) of the harvesting machine ( 1 ).

10. The agricultural harvesting machine according to claim 1 , configured as a self-propelled forage harvester ( 1 ).

11. An agricultural machine embodying a field chopper, the field chopper comprising:
at least one working assembly ( 2 , 3 ) for processing a crop stream;
a discharge accelerator ( 4 ) for the processed crop configured to be installed in entirety in an operating position (P B ) downstream of the at least one working assembly ( 2 , 3 ) in a flow path of the crop stream and, to be removable from the operating position (P B );
a conveyor chute ( 12 ); and
means for moving the discharge accelerator ( 4 ) out of the operating position (P B ) into an access position (P Z ) within a maintenance space ( 5 ) of the field chopper;
wherein the means for moving comprises a pivotable support of the discharge accelerator ( 4 ) with respect to a machine frame ( 9 ) in a form of a cab carrier ( 10 ) of the field chopper;
wherein the discharge accelerator ( 4 ) comprises at least one accelerating mechanism ( 20 ) and an enclosing housing ( 21 ), wherein the accelerating mechanism ( 20 ) is rotatably supported by a shaft ( 8 ) extending in parallel to a front axis of the field chopper; and
wherein the conveyor chute ( 12 ) adjoins the discharge accelerator ( 4 ).
