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.
Claims7
A threshing apparatus comprising:
- a conveyor for transferring harvested crop in a direction;
- at least one threshing rotor for receiving 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 rotatable about an axis at a right angle to the axis of rotation of the threshing rotor, the feed roll comprising a plurality of projections configured to feed the harvested crop from the conveyor to the at least one threshing rotor and 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 drive coupled to the at least one threshing rotor,
- a drive shaft parallel to the axis of rotation of the feed roll;
- and
- a mechanical connection between the drive shaft and the feed roll so that the feed roll is driven in synchronism with the rotation of the at least one threshing rotor.
