Abstract
The reel (4′) of the combine header of the invention comprises a rotatable central tube (10) with side members (15,16).
Claims20
A header for a combine harvester, comprising a cutter bar and a reel, wherein the reel comprises:
- a central tube rotatable about a central axis and supported by two lateral supports and an intermediate support;
- a first reel portion and a second reel portion, wherein the first and second reel portions are positioned on opposite sides of the intermediate support, and each reel portion of the first and second reel portions comprises:
- a plurality of transverse members mounted on the central tube;
- a plurality of tine bars;
- and
- a plurality of tines attached to the plurality of tine bars, wherein the plurality of tine bars are coupled to the plurality of transverse members at regular intervals along a circumference of the plurality of transverse members;
- wherein the reel has an upper half above the central axis and a lower half below the central axis;
- and
- wherein two slanted transverse members comprise a first slanted transverse member of the plurality of transverse members of the first reel portion and a second slanted transverse member of the plurality of transverse members of the second reel portion, the two slanted transverse members are positioned on opposite sides of the intermediate support, the two slanted transverse members are configured to be maintained in slanted positions with respect to the intermediate support during rotation of the reel, the slanted positions are such that the two slanted transverse members are closer together in the lower half of the reel than in the upper half of the reel, the plurality of tine bars of the first reel portion is pivotably connected to the first slanted transverse member so that rotation of the reel generates a first reciprocating motion of at least a portion of the plurality of tine bars of the first reel portion in an axial direction of the reel, and the plurality of tine bars of the second reel portion is pivotably connected to the second slanted transverse member so that the rotation of the reel generates a second reciprocating motion of at least a portion of the plurality of tine bars of the second reel portion.
