  • Patent number: 7473168
    Abstract: A new and improved conveyor feeder house chain slat having a unique shape and structure that provides sufficient structural rigidity to improve crop throughput while reducing clogging of crop material. The unique slat also provides additional support to the chain. Because the chain rides on the rear of the elongated section of the slat, the slat contacts the feed house, rather than the chain, reducing chain wear, overheating and lubricant evacuation. Because of the new slat configuration, the slats can be secured to the chain with removable securing means, enabling easier replacement of an individual slat if necessary.

  • Patent number: 6979261
    Abstract: An agricultural combine for harvesting, threshing and separating an agricultural crop includes a processing assembly. A conveying mechanism moves harvested crop material to the crop processing assembly. A rotating member feeds crop material from the conveying mechanism to the processing assembly. An airflow diverter is transversely positioned adjacent the rotating member to divert a potion of the airflow from the conveying mechanism into the crop processing assembly independent of the crop flow path.
