Feederhouse assembly having a rotational shaft with fluid passages
A feederhouse assembly for an agricultural harvester includes a feederhouse comprising an inlet end, a rotational shaft coupled to the feederhouse and defining a plurality of fluid passages therethrough, and a frame adjacent the inlet end and arranged to pivot about the rotational shaft relative to the feederhouse. The frame defines a crop opening therethrough and is configured to carry a harvesting header. An agricultural harvester includes a chassis, the feederhouse assembly mounted to the chassis, and a processing system carried by the chassis and structured to receive crop material from the feederhouse.
1. A feederhouse assembly for an agricultural harvester, the feederhouse assembly comprising:
a feederhouse comprising an inlet end;
a rotational shaft coupled to the feederhouse and defining a plurality of fluid passages therethrough, wherein the fluid passages are configured to be connected to a pressurized fluid source carried by the agricultural harvester; and
a frame adjacent the inlet end and arranged to pivot about the rotational shaft relative to the feederhouse, the frame defining a crop opening therethrough and configured to carry a harvesting header.
2. The feederhouse assembly of claim 1 , wherein the rotational shaft comprises a unitary body defining a cylindrical outer surface and an inner surface of each of the fluid passages.
3. A feederhouse assembly for an agricultural harvester, the feederhouse assembly comprising:
a feederhouse comprising an inlet end;
a rotational shaft coupled to the feederhouse and defining a plurality of fluid passages therethrough;
a frame adjacent the inlet end and arranged to pivot about the rotational shaft relative to the feederhouse, the frame defining a crop opening therethrough and configured to carry a harvesting header; and
a plurality of hoses carried by the frame and connected to the fluid passages.
4. The feederhouse assembly of claim 3 , wherein the plurality of hoses are disposed within the frame.
5. A feederhouse assembly for an agricultural harvester, the feederhouse assembly comprising:
a feederhouse comprising an inlet end;
a rotational shaft coupled to the feederhouse and defining a plurality of fluid passages therethrough;
a frame adjacent the inlet end and arranged to pivot about the rotational shaft relative to the feederhouse, the frame defining a crop opening therethrough and configured to carry a harvesting header; and
at least one hydraulic cylinder configured to move the frame with respect to the feederhouse, wherein the plurality of fluid passages are in fluid connection with the at least one hydraulic cylinder.
6. The feederhouse assembly of claim 5 , wherein the at least one hydraulic cylinder is configured to adjust a pitch of a face of the frame with respect to the feederhouse.
7. The feederhouse assembly of claim 5 , wherein the at least one hydraulic cylinder comprises at least two hydraulic cylinders.
8. The feederhouse assembly of claim 5 , wherein the at least one hydraulic cylinder comprises at least one double-acting hydraulic cylinder.
9. An agricultural harvester, comprising:
a chassis;
a feederhouse comprising an inlet end and carried by the chassis;
a rotational shaft coupled to the feederhouse and defining a plurality of fluid passages therethrough, wherein the fluid passages are configured to be connected to a pressurized fluid source carried by the agricultural harvester;
a frame adjacent the inlet end of the feederhouse and arranged to pivot about the rotational shaft relative to the feederhouse, the frame defining a crop opening therethrough and configured to carry a harvesting header; and
a processing system carried by the chassis and structured to receive crop material from the feederhouse.
10. The agricultural harvester of claim 9 , further comprising a harvesting header coupled to the frame.
11. The agricultural harvester of claim 9 , further comprising a grain bin carried by the chassis and structured to receive grain from the processing system.
