Abstract
A threshing apparatus for an agricultural harvester has an axial threshing rotor driven by a power unit from its rearward end. The axial threshing rotor is connected at its forward end to a dynamic feed roll through a drive train including a drive connected to the axial threshing rotor and having an output shaft extending to a side of the dynamic feed roll where it is connected by either a gear set or a pulley drive.
Claims11
A threshing apparatus comprising:
- a conveyor that transfers harvested crop in a direction;
- at least one threshing rotor that receives harvested crop from the conveyor for separating grain material, the at least one threshing rotor driven for rotation about an axis;
- a feed roll interposed between the conveyor and the at least one threshing rotor, the feed roll rotates about an axis at a right angle to the axis of rotation of the threshing rotor, the feed roll comprising a plurality of projections that feed the harvested crop from the conveyor to the at least one threshing rotor and, wherein the projections of the feed roll move at a higher speed than the harvested crop to knock out stones from the harvested crop;
- and
- a drive train connected to and driven by the threshing rotor, the drive train comprising:
- a first drive shaft coupled to the at least one threshing rotor that is rotated by the threshing rotor,
- a second drive shaft parallel to the axis of rotation of the feed roll and coupled to the feed roll for rotating the feed roll;
- and
- a mechanical connection between the first drive shaft and the second drive shaft so that the feed roll is driven in synchronism with the rotation of the at least one threshing rotor.
