US 7,987,917 B1 · Multistage crop roller

Abstract

The multi-stage crop termination system includes a main frame assembly connected to first and second roller frames. A first roller is installed in the first roller frame and a second roller is installed in the second roller frame. A compression frame extends between the main frame and the second roller frame so that a downwardly compression force is applied to the second roller. In the preferred embodiment, the first roller is a smooth drum and the second roller is a central cylindrical drum with a plurality of crimping bars extending outwardly from the drum. In operation, crops are flattened by the first roller and then crimped by the second roller. A pivot joint between the first roller frame and the second roller frame ensures that the second roller is able to maintain contact with the ground as the system traverses uneven terrain.

Dependent claims

A multi-stage crop roller system, the system comprising:

a main frame assembly;
a first crop roller frame connected to the main frame assembly;
a first crop roller connected to the first roller frame;
a second crop roller frame connected to the first crop roller frame;
a second crop roller connected to the second crop roller frame, the second crop roller comprising a plurality of crimping bars, and;
a compression frame extending between the main frame assembly and the second crop roller frame, the compression frame exerting a downwardly force on the second crop roller via the second crop roller frame;
wherein as a motive means urges the system forward, the first and the second crop rollers roll over and crimp crops and thereby effectively terminate the crops.
