Reel for a harvester
View Patent ↗A reel for a harvester, such as for a combine harvester. The reel includes a reel supporting pipe and star-shaped supports at the ends of the reel, the star arms being connected to each other by means of tine rods which run parallel to the supporting pipe, wherein the star-shaped supports are specifically at least partially reinforced as a result of which at least one of the tensile and compression forces acting on the supporting pipe can be absorbed by one or more tine rods.
1. A reel for a harvester, the reel comprising:
a reel supporting pipe; and
star-shaped supports, each star-shaped support comprising:
a hub comprising a cylindrical portion having:
an interior surface forming an opening,
an exterior surface, and
a plurality of star arms extending from the exterior surface;
wherein the opening is co-axially disposed over an end portion of the reel supporting pipe such that the interior surface of the cylindrical portion of the hub extends over an exterior surface of the end portion of the reel supporting pipe;
wherein each start arm comprises at least two triangular shaped plates, each plate having:
a shortest side positioned on the exterior surface of the cylindrical portion of the hub and extending along a length of the hub, and
a side running outwardly in a radial direction from the hub; and
wherein the star-shaped supports are connected by tine rods that run parallel to the reel supporting pipe.
2. The reel of claim 1 wherein adjacent arms of the plurality of star arms for each star-shaped support are connected to each other by a reinforced plate.
3. The reel of claim 1 wherein at least one of the tine rods is composed of several rod segments.
4. The reel of claim 3 wherein the rod segments are connectable to each other by an interlocking connection.
5. The reel of claim 3 wherein the rod segments are connectable to each other near a tip of an arm for a star-shaped support that is positioned intermediate of the reel supporting pipe.
6. The reel of claim 1 wherein bracings comprising cables are fixed at their ends to the reel supporting pipe and the cables are stretchable in a direction of a longitudinal axis of the supporting pipe.
7. The reel of claim 1 wherein at least one of tine rods is provided with at least one spring tine having a coil that is at least partially embedded in the at least one tine rod.
8. The reel of claim 1 wherein at least one spring tine is fixed to at least one of the tine rods by a bracket.
