Abstract
A finger roller for agricultural machines is provided. At least one finger disk is disposed on a shaft of the finger roller and has a hub, over the periphery of which are distributed and project a plurality of fingers. The fingers are at least slightly elastically deformable, and a side of each finger that faces in the direction of rotation of the finger roller is markedly roughened, for example by being provided with fine ribs, studs or knobs.
Claims7
A finger roller for agricultural machines, comprising:
- a shaft;
- at least one finger disk that is disposed on said shaft and has a hub;
- and
- a plurality of fingers distributed over and projecting from a periphery of said hub, said fingers and said hub forming an integrally formed injection molded unit, wherein said fingers are at least slightly elastically deformable, wherein a side of each of said fingers that faces in a direction of rotation of said finger roller is markedly roughened, wherein said fingers are deflectable counter to a direction of rotation of said finger roller, and wherein said roughened side of said fingers is produced by fine ribs, studs, or knobs.

A finger roller for agricultural machines, comprising:
- a shaft;
- and
- at least one finger disk having a hub and a plurality of fingers, said fingers and said hub forming an integrally formed injection molded unit comprising an elastomeric material which extends in a continuous manner to and between said hub and said fingers, said hub having a central opening for receiving said shaft therethrough such that said at least one finger disk is disposed on said shaft with said shaft and said hub being co-axial with one another;
- and
- said plurality of fingers being distributed over and projecting from a periphery of said hub, said fingers being at least slightly elastically deformable and including a plurality of projections on a side of each of said fingers that faces in a direction of rotation of said finger roller, the projections on each respective finger projecting outwardly in the direction of rotation relative to the balance of the side of the respective finger such that the projections are the forwardmost surfaces of the side of the respective finger as viewed in the direction of rotation, and said fingers being resiliently deflectable counter to the direction of rotation of said finger roller and, due to the continuously extending elastomeric material extending to and between said fingers and said hub, said hub being resiliently deformable upon deflection of said fingers beyond a threshold degree of deflection.
