Feeding mechanism of a header for a combine harvester
View Patent ↗A header for a combine harvester capable of improving the flow of grain from the header to a feeder house and reducing grain buildup about a void proximate an aft section of the header is disclosed. The header includes a chassis and a cross auger extending in a widthwise direction of the chassis. The header also includes a feed mechanism mounted on the chassis proximate a posterior end of the cross auger and within the void of the header.
1. A header for a combine harvester comprising:
a chassis having:
a forward portion,
a rearward portion opposite the forward portion, and
an outlet at an aft of the rearward portion;
a cross auger extending in a widthwise direction of the chassis for conveying a flow of grain rearwardly thereof, wherein the cross auger is positioned about the rearward portion adjacent a void proximate the outlet; and
a feeding mechanism comprising a pair of feed rollers mounted on the chassis within the void and proximate a posterior end of the cross auger for receiving the flow of grain from the cross auger and actively conveying the flow of grain rearwardly thereof so as to preclude the flow of grain from being hindered downstream of the cross auger.
2. The header of claim 1 , wherein the feeding mechanism is positioned below the cross auger.
3. The header of claim 1 , further comprising an auger trough in side to side relation with the cross auger,
wherein the outlet is in fluid communication with the auger trough for receiving a flow of grain from the auger trough, and
wherein the feeding mechanism receives a flow of grain from the auger trough for feeding the flow of grain towards the outlet.
4. The header of claim 1 , wherein the pair of feed rollers are a pair of counter rotating feed rollers.
5. The header of claim 1 , wherein the feeding mechanism floats between at least first and second positions.
6. The header of claim 1 , wherein the feeding mechanism receives a flow of grain from the cross auger and is adjustably positioned based upon the flow of grain.
7. A combine harvester comprising:
a feeder house having an inlet for receiving a flow of grain and a feeder drum adjacent the inlet; and
a header attachable to the combine harvester adjacent the feeder house, the header including:
a chassis defining a void adjacent an outlet of the header,
a cross auger extending in a widthwise direction of the chassis for conveying a flow of grain towards the feeder house, and
a feeding mechanism comprising a pair of counter rotating feed rollers mounted on the chassis within the void and situated between the cross auger and the feeder drum for receiving the flow of grain from the cross auger and actively conveying the grain to the feeder house so as to preclude the flow of grain from being hindered as it travels to the feeder house, wherein the feeding mechanism floats between a first position and a second position.
8. The combine harvester of claim 7 , wherein the feed mechanism is mounted on the chassis proximate a posterior end of the cross auger.
9. The combine harvester of claim 7 , wherein the header further comprises an auger trough in side to side relation with the cross auger,
wherein the outlet is in fluid communication with the auger trough for receiving a flow of grain from the auger trough, and
wherein the feeding mechanism receives a flow of grain from the auger trough for feeding the flow of grain towards the outlet.
10. The combine harvester of claim 9 , wherein the feeding mechanism is positioned between the cross auger and the outlet.
11. The combine harvester of claim 7 , wherein the feeding mechanism is positioned below a central longitudinal axis of the cross auger and a central longitudinal axis of the feeder drum.
12. The combine harvester of claim 7 , wherein the feeding mechanism receives a flow of grain from the cross auger and is adjustably positioned based upon the flow of grain.
13. A combine harvester comprising:
a feeder house having an inlet and a feeder drum adjacent the inlet; and
a header attachable to the combine harvester adjacent the feeder house, the header including:
a frame defining a void adjacent an outlet of the header,
a conveyor extending in a widthwise direction of the frame for feeding a flow of grain towards the inlet of the feeder house, and
a feeding mechanism mounted on the frame within the void and positioned between the conveyor and the feeder drum for receiving the flow of grain from the conveyor and actively conveying the grain to the feeder house so as to preclude the flow of grain from being hindered as it travels to the feeder house, the feeding mechanism including a first feed roller and a second feed roller spaced from the first feed roller defining a receiving gap for the flow of grain therebetween.
14. The combine harvester of claim 13 , wherein the outlet is in communication with the inlet of the feeder house; and the header further comprises a second conveyor for conveying grain towards the outlet, wherein the conveyor conveys grain towards a center of the frame, and the feeding mechanism is positioned between the second conveyor and the outlet.
