Abstract
A harvester reel for an agricultural harvester header includes a central rotatable shaft; a plurality of reel tine bars and a cam assembly for guiding rotation of the plurality of reel tine bars. The reel tine bars extend widthwise across the reel and are connected to the central rotatable shaft for rotation therewith. Each of the plurality of reel tine bars include a tine. The cam assembly includes a cam and a diverter adjacent the cam. The diverter is movable between a disengaged position, in which the cam does not guide rotation of the tine bars, and an engaged position, in which the cam does guide rotation of the tine bars. The diverter is biased toward the engaged position.
Claims20
A harvester reel of an agricultural harvester header comprising:
- a central rotatable shaft;
- a plurality of reel tine bars extending widthwise across the harvester reel and connected to the central rotatable shaft for rotation therewith, each of the plurality of reel tine bars comprising a cam follower and a tine;
- and
- a cam assembly selectively guiding rotation of the plurality of reel tine bars;
- wherein the cam assembly comprises a primary cam associated with a primary tine bar guiding mechanism and a secondary cam associated with a secondary tine bar guiding mechanism and a diverter operably attached to the secondary cam;
- wherein the diverter is selectively movable between a disengaged position, in which the secondary cam does not guide rotation of the tine bars, and an engaged position, in which the secondary cam does guide rotation of the tine bars;
- and
- wherein the diverter is biased toward the engaged position and operates in conjunction with the secondary cam in pivoting the cam follower that enables retraction of the tine along a central longitudinal axis into a cammed state with the retracted tine being positioned at an acute angle to the perimeter of the harvester reel, resulting in an enlarged opening between the plurality of reel tine bars, the tine, and a cutterbar that does not enable contact between the cutterbar and the tine.
