A first rotatable shaft is secured to the second side of the attachment plate. A central axis of the first rotatable shaft extends in a first direction. A first motor is connected to the first rotatable shaft to cause the first rotatable shaft to rotate. An auger support member is connected to the first rotatable shaft so as to rotate with a rotation of the first rotatable shaft. A second rotatable shaft is secured to the auger support member, and a central axis of the second rotatable shaft extends in a second direction that is transverse to the first direction. A second motor is connected to the second rotatable shaft to cause the second rotatable shaft to rotate, thereby rotating an auger.

  • Patent number: 9132952
    Abstract: A mobile fiber dispenser that dispenses a variety of types and lengths of pre-cut fibers. The main body of the dispenser is a cylindrical hopper. The pre-cut fibers are loaded into the top of the hopper. Inside the body of the dispenser is a counter auger that keeps the fibers from bridging and clumping. As the fibers pass through the counter auger, they drop into a feed auger that pushes the fibers through an auger housing toward a declumping apparatus. The counter auger and feed auger rotate in the same direction. The declumping apparatus at the end of the auger housing and feed auger intercepts the fibers as the fibers exit the auger housing. The declumping apparatus provides an even distribution of the pre-cut fiber through a discharge chute that extends downward from the auger housing. The fibers are discharged into a field vehicle's mixing process or other collection apparatus.

A mixer container is supported by the extension such that the container is disposed between the chassis and the second end of the extension.

  • Patent number: 6203184
    Abstract: A blender for delivery of blend additives to a plastics extrusion device has a mixing chamber for reception of materials to be blended. Batches of blend materials are delivered to the mixing chamber from material supply bins via a weight hopper. Within the mixing chamber, a mixing screw circulates and mixes the blend materials prior to discharge through an outlet to an extrusion process line. As material is discharged, a material level sensor is uncovered and calls for a further batch of blend materials to be discharged from the weigh hopper into the mixing chamber. The screw has a pair of mixing blades of opposed pitch to direct material inwardly from outer ends of the screw towards a center of the screw located above the outlet. Excess material above process demand requirements is delivered to the outlet by the screw. This excess material is directed upwardly away from the outlet and recirculated towards outer ends of the screw and remixed without material within the mixing chamber.
