Harvester tine having a front-to-rear parting line in its strap and finger portion and one or more depressions on its finger portion
A tine for use with a harvester. The tine is preferably an injection molded polymer pickup reel tine, which uses a front-to-rear mold parting line direction. The tine preferably has a snap ring or strap portion which is configured to engage a bat tube, as well as a finger portion which is configured to engage the crop during harvesting. Preferably, the front-to-rear parting line is along both portions. The front-to-rear parting line allows for the ability to provide a deep front-to-rear cross section for rigidity at the high stress area of the tine. Two front-to-rear material saving features can be utilized to minimize material usage and allow for relative consistent wall thickness, which results in a rigid cross section that maintains deflection stability in the normal direction of deflection. The preferred form of the tine cross section includes three deep oval sections or projections, connected by two oval depressions, but other variations are entirely possible while still resulting in effectively the same benefits.
1. A tine configured to engage a bat tube of a pick-up reel of a harvester, wherein the tine comprises a strap portion configured to engage and wrap around the bat tube and a finger portion which extends longitudinally from the strap portion to an opposite end of the tine, wherein the finger portion comprises a front and a back, wherein the finger portion comprises a plurality of depressions and a plurality of projections both on the front of the finger portion and the back of the finger portion, wherein the plurality of projections and the plurality of depressions run parallel to each other along the front and back of the finger portion of the tine, and wherein the plurality of projections and the plurality of depressions run longitudinally in a direction from the strap portion of the tine to the opposite end of the tine, along the front and back of the finger portion of the tine.
2. A tine as recited in claim 1 , wherein the tine is injection molded and formed of a polymer.
3. A tine as recited in claim 1 , said tine comprising a front-to-rear parting line which runs along the finger portion of the tine and which is located on sides of the finger portion of the tine as opposed to being located on the front and back of the finger portion of the tine.
4. A tine as recited in claim 1 , wherein each of the plurality of projections is oval.
5. A tine as recited in claim 1 , wherein the tine is a single piece.
6. A tine as recited in claim 1 , wherein the plurality of projections and the plurality of depressions start in the strap portion of the tine.
