Self-adjusting object deflector for an agricultural harvester feeder
View Patent ↗A feeder assembly for an agricultural harvester, including a first shaft, a second shaft opposite the first shaft, a chain extending around the first shaft and the second shaft, wherein the chain is configured to convey agricultural through the agricultural harvester, and a self-adjusting object deflector assembly positioned between the first shaft and the second shaft, wherein the self-adjusting object deflector assembly comprises a deflector biased against the chain and configured to block the agricultural material from interfering with a connection between the chain and the first shaft.
1. A feeder assembly for an agricultural harvester, comprising:
a frame;
a first shaft connected to the frame including a sprocket;
a second shaft opposite the first shaft;
a chain extending around the first shaft and the second shaft establishing an upper run and a lower run, and engaging the sprocket defining a connection therebetween;
a self-adjusting object deflector assembly that self-adjusts and is attached to a support member of the frame and positioned between the first shaft and the second shaft, in front of the first shaft, and adjacent to the first shaft and the connection, wherein the self-adjusting object deflector assembly comprises a deflector positioned entirely above a section of a lower run of the chain and a biasing member, and
the biasing member connected to the deflector to bias a skid thereof against the lower run of the chain to prevent agricultural material from entering an interface between the chain and the first shaft, wherein at least a portion of the skid extends under at least a portion of the sprocket.
2. The feeder assembly of claim 1 , wherein the connection between the chain and the first shaft is formed by teeth of the sprocket engaging the chain.
3. The feeder assembly of claim 1 , wherein the first shaft is connected to a drive, and the drive induces the first shaft to rotate.
4. The feeder assembly of claim 1 , comprising a second chain extending around the first shaft and the second shaft.
5. The feeder assembly of claim 4 , comprising at least one slat extending between the chains.
6. The feeder assembly of claim 1 , wherein the deflector includes a deflector arm.
7. The feeder assembly of claim 6 , wherein the skid is connected to the deflector arm.
8. The feeder assembly of claim 7 , wherein the skid is removable from the deflector arm.
9. The feeder assembly of claim 6 , wherein the biasing member comprises a torsion member connected to the deflector arm, and configured to rotationally bias the deflector arm toward the chain.
