  • Patent number: 6443194
    Abstract: A screw anchor adjustable density control device is provided for use with a bagging machine for bagging material into bags having a closed end and an open mouth. The bagging machine comprises a wheeled frame having a tunnel thereon which includes an intake end for receiving the material to be bagged and an output end adapted to receive the open mouth of the bag. A selectively rotatable screw anchor is secured to the wheeled frame within the tunnel and extends rearwardly therefrom into the material being packed within the bag. The rotational rate of the screw anchor is selectively varied for varying the density of the material within the bag. Preferably, the screw anchor is selectively movable between retracted and extended positions.

  • Patent number: 5799472
    Abstract: A bag pan is provided for an agricultural feed bagging machine wherein the bag pan is supported by a pair of bag pan support arms which are vertically movably mounted in guide track support housings having guide tracks therein. The upper ends of the bag pan support arms have rollers thereon which engage track members in the guide track housings. The upper ends of the support arms are individually connected to a hydraulic cylinder by means of a flexible cable. The individual connection of the bag pan support arms with the hydraulic cylinder enables the bag pan on the support arms to conform to uneven ground conditions beneath the bag pan.

  • Patent number: 5775069
    Abstract: A density control cable is provided on an agricultural bagging machine for engagement with the material being bagged as the material is forced past the density control means into the bag being filled with agricultural material. A beveled press plate is provided on the bagging machine frame rearwardly of the rotor on the bagging machine for forcing the agricultural material upwardly, rearwardly and outwardly as the material passes thereby. A hydraulic cylinder is operatively connected to the density control cable to enable the width of the loop of the cable to be selectively varied.

  • Patent number: 5452562
    Abstract: A compost bagging machine is described including a wheeled frame having a tunnel mounted thereon which is adapted to receive the opened mouth of a clear and transparent bag. The inside surface of the tunnel is provided with a plurality of spaced-apart flutes which create air channels in the material within the bag. An elongated perforated pipe is also positioned within the material in the bag and the bagging machine moves relative to the bag during the bagging operation. The presence of air in the channels created by the flutes and the air present in the perforated pipe ensures that sufficient air will be present in the mass to achieve complete decomposition of the material. The method of composting material within the clear and transparent bag is also disclosed.
