Abstract
The mechanism alters the position of a set of auger fingers positioned in front of a feederhouse opening relative to auger fingers on the outer ends of a transverse auger of a header of a combine harvester. A center finger auger shaft is positioned between two outer finger auger shafts. An outer shaft plate having a series of radially place holes may be adjusted to change the position of a center shaft plate. This changes the position of the center auger finger shaft affixed to the center shaft plate. This permits the auger fingers to be moved either towards or away from the header floor.
Claims17
A header of a combine harvester comprising:
- a. an auger;
- b. a reciprocating outer auger finger shaft positioned within the auger, said outer finger shaft having a series of outer fingers affixed thereon;
- c. a reciprocating center finger shaft positioned within the auger and attached to the outer auger shaft, said center finger shaft having a series of center fingers affixed thereon;
- and
- d. a means for adjusting the center finger shaft relative to the outer finger shaft.
In a header for an agricultural harvester, said header attached to a feederhouse, said feederhouse positioned near a midpoint of the header, said header having an frame supporting a pair of opposing sidewalls, a floor positioned between the sidewalls, a stripper and a sickle bar attached to the floor, an auger rotationally affixed between the side walls, an improvement comprising:
- a. a reciprocating outer finger shaft rotationally affixed to the side wall and co-axial to the auger;
- b. a reciprocating center finger shaft rotationally affixed to the outer finger shaft;
- c. a plurality of outer fingers affixed to the outer finger shaft, each outer finger having an outer finger tip;
- d. a plurality of center fingers affixed to the outer finger shaft, each center finger having a center finger tip;
- and
- e. a means for adjusting the plurality of the tips of the center fingers relative to the tips outer fingers and simultaneously relative to the floor.
