Drive mechanism for augers of an agricultural harvester header
View Patent ↗A header of an agricultural harvester for the transport of a flow of crop from a header to a combine feeder house. The header includes a frame having a floor, a conveyor assembly, and a drive mechanism. The conveyor assembly is mounted above the floor to urge a flow of crop material during harvesting operations, and the drive mechanism operatively connects to the conveyor assembly to drive movement of the conveyor assembly. The drive mechanism includes a drive motor mounted to the frame beneath the floor about a medial section of the header.
1. A header for an agricultural harvester comprising:
a frame having a floor;
a conveyor assembly mounted above the floor to urge a flow of crop material during harvesting operations, the conveyor assembly comprising a first rotatable auger, a second rotatable auger and a feeder assembly between the first and second rotatable augers;
a drive mechanism operatively connected to the conveyor assembly to drive movement of the conveyor assembly, the drive mechanism comprising a drive motor mounted to the frame beneath the floor about a medial section of the header; and
a rotary connection connecting the drive mechanism to the conveyor assembly, the rotary connection disposed between inner ends of the first rotatable auger and the second rotatable auger.
2. The header of claim 1 , wherein the first rotatable auger and the second rotatable auger extend in a widthwise direction of the header.
3. The header of claim 1 , wherein the feeder assembly has extension members rotatable about a central rotational axis of the feeder assembly.
4. The header of claim 1 , further comprising a mount supporting the conveyor assembly on the frame at the medial section of the header.
5. The header of claim 4 , wherein the drive mechanism further comprises an endless belt operatively connected between the conveyor assembly and the drive motor, and wherein the mount encapsulates the endless belt between the conveyor assembly and the floor.
6. The header of claim 1 , wherein the feeder assembly is coaxial with the first and second augers.
7. The header of claim 1 , wherein the first and second augers are coaxial.
8. The header of claim 1 , wherein the feeder assembly comprises:
a central rotational axis;
an axis extending across the feeder assembly and offset from the central rotational axis; and
an extension member extending from and pivotably connected to the axis.
9. The header of claim 8 , wherein the feeder assembly further comprises an adjustment mechanism operatively connected to the axis for adjusting the offset of the axis from the central rotational axis of the feeder assembly.
10. The header of claim 9 , wherein the feeder assembly includes a plurality of extension members extending from the axis.
11. The header of claim 9 , wherein the feeder assembly includes a housing for housing the axis and the extension member.
12. The header of claim 9 , wherein the feeder assembly includes a housing that includes a slot, and wherein the extension member extends through the slot.
13. The header of claim 1 , wherein the first rotatable auger is spaced from the second rotatable auger, and the feeder assembly is disposed adjacent an inner end of the first rotatable auger and the second rotatable auger.
