Abstract

A combine harvester with an axial flow crop processor with a rotor mounted for rotation inside a rotor housing arranged longitudinally with respect to the harvester. A feed beater is mounted for rotation on a substantially transverse axis and serves to tangentially impel crop material into the crop processor. A drive system drives the rotor and feed beater, wherein the drive system includes a rotor drive device for transmitting torque from a drive stage to the rotor, and a drive connection between the rotor drive device and the beater.

First claim

The invention claimed is:

1. A combine harvester comprising:
an axial flow crop processor with a rotor mounted for rotation inside a rotor housing and arranged substantially longitudinally with respect to the harvester;
a feed beater mounted for rotation on a substantially transverse axis and serving to tangentially impel crop material into the crop processor; and,
a drive system for driving the rotor and feed beater;
wherein the drive system includes:
a rotor drive device which is connected to a rear end of the rotor and is configured to transmit torque from a drive stage to the rotor; and,
a drive connection between the rotor drive device and the beater.

2. A combine harvester according to claim 1 , wherein the rotor drive device comprises a transverse driveshaft driven by the drive stage and a gearbox arranged to transfer motion from the transverse driveshaft to the rotor.

3. A combine harvester according to claim 2 , wherein the drive connection comprises a coupling to the gearbox.

4. A combine harvester according to claim 3 , wherein the coupling comprises a universal joint.

5. A combine harvester according to claim 1 , wherein the drive connection comprises a belt drive system having a driving pulley connected to the rotor drive device and a driven pulley connected to the feed beater.

6. A combine harvester according to claim 5 , wherein the belt drive system comprises a first belt drivingly connecting the driving pulley to an intermediate transfer pulley, and a second belt drivingly connecting the transfer pulley to the driven pulley.

7. A combine harvester according to claim 1 , wherein the drive stage is an intermediate drive stage driven by an internal combustion engine.

8. A combine harvester according to claim 7 , wherein the intermediate drive stage comprises a drive pulley drivingly connected to the engine via a belt drive, and wherein the drive pulley is drivingly coupled to the rotor drive device via a multi-ratio gearbox.

9. A combine harvester according to claim 7 , wherein the intermediate drive stage is driven by the engine via a stepless variable transmission.

10. A combine harvester according to claim 9 , wherein the stepless variable transmission comprises a variator belt drive.

11. A combine harvester according to claim 1 , wherein the drive connection comprises a stepless variable transmission.

12. A combine harvester according to claim 11 , wherein the stepless variable transmission comprises a variator belt drive.

13. A combine harvester according to claim 1 , wherein the drive stage is positioned on one machine side, and wherein the drive connection is arranged on an opposite machine side.
