  • Patent number: 9284126
    Abstract: A chain tensioning apparatus for tensioning a chain of an agricultural barn cleaner. The barn cleaner chain is moved by a motor-driven drive sprocket mounted in a drive tower after contacting a first idler rotatably mounted to the drive tower. A second idler is mounted to the frame and positioned further away from the drive tower than the first idler such that, as the chain moves toward the drive tower, the chain contacts the second idler before contacting the first idler. A chain tensioning idler contacts the chain between the first idler and the second idler and is capable of movement in a direction transverse to the movement of the chain. A biasing member biases the chain tensioning idler toward a take-up position and away from a chain-taut position.

  • Publication number: 20160016132
    Abstract: A feed mixer with a vertical screw and one or more paddles that enhance mixing efficiency. Each of the paddles has a guide portion that extends below the flighting on the screw, and an attachment portion by which the paddle is connected to the screw. During rotation of the screw, the paddle both draws new material inward onto the flighting and helps retain material on the flighting.

  • Publication number: 20140036619
    Abstract: A material processing machine having a rotating element formed of a core rotatable about a generally vertical axis, and a top cap having a pair of facets which abut together at a join line. The join line extends downward from perpendicular to the generally vertical axis at an angle. The core has a continuous outer wall that is substantially vertical, and the facets extend inward from the outer wall to the join line at a non-perpendicular angle. Each of the facets extends inward from the outer wall to the join line at an angle that is different from angle of the other facet.

  • Patent number: 7281843
    Abstract: A vertical agricultural mixer employs a pair of vertical mixing augers in combination with a pair of asymmetrical, half pyramid-shaped transfer protrusions adjacently disposed along each opposed sidewall between the augers in a mixing tub. The transfer protrusions are differently shaped with tips which are vertically spaced from each other along a vertical line on each sidewall. The transfer protrusions create a pressure gradient to allow material mixed in the tub to transfer to an adjacent mixing auger more efficiently so that mixing action is optimized and dead mixing spots are prevented.
