  • Patent number: 5286161
    Abstract: A method of producing a silage removal channel. The method comprises the steps of disposing an inflatable tube within an empty silo, inflating the tube, filling the silo with feedstuff, deflating the tube and then withdrawing the same from the interior of the silo to create the silage removal channel within the feedstuff. The created channel is disposed from the uppermost surface of the feedstuff to a discharge port disposed in the exterior wall of the silo. When required feedstuff is introduced into the mouth of the channel, it gravitates through the channel to the discharge port where it may be removed from the silo.

  • Patent number: 4998855
    Abstract: An arrangement for storing and removing bulk material in a round pile, in which a truss is rotatable about a vertical axis on a substructure. The truss carries a material depositing belt and a bulk material receiver which is pivotable in a vertical direction. A counterweight on the truss balances weight. The substructure is hopper-shaped. The truss is mounted on the substructure by a bearing, and rollers carry the truss which runs on the substructure. The bulk material receiver is in the form of a drag that conveys to a hopper of the substructure. This hopper has a bottom with a conveying medium under which a conveyor belt runs. The bearing has a large diameter annular track that is elevated on posts on the substructure. A rotatable plough located at the bottom of the hopper is the single conveying element on the hopper bottom.

  • Patent number: 4828448
    Abstract: Previously belts, drag chains or screw feeders have been used to discharge a bulk material, such as wood pulp and the like, from a storage bin or hopper at the required rate. A problem with such feeders is obtaining uniform withdrawal of material from the full area of the bin, as typically some areas of the bin remain stagnant, and further there may be areas of consolidation and compaction of the bulk material against the walls of the bin. The present invention overcomes these problems by providing a discharge feeder in which an opening of selected width travels back and forth uniformly under the bin outlet. By a system of belts and pulleys, the surface of the feeder in contact with the bulk materials remains stationary with respect to the materials, while the opening itself traverses the length of the bin, allowing a uniform non-consolidating feed of the bulk materials.

  • Patent number: 4806058
    Abstract: The device is operative to discharge the triangular ridge of grain, which remains in the bottom of a cylindrical storage bin after the bulk of the bin contents has been discharged by gravity through a central outlet in the bin floor. The device comprises a vertical, rotatable, driven shaft mounted to extend upwardly from the outlet. A free-floating sweep arm is pivotally attached at its inner end to the base of the shaft, so that said arm can rise or fall in a vertical plane. The sweep arm extends outwardly to the wall of the bin. A plurality of parallel, spaced apart, sationary fins protrude downwardly from the undersurface of the sweep arm. The fins are arranged at a trailing angle of about 45.degree., relative to the longitudinal axis of the sweep arm. The forward end of each fin is located on a radius which is equal to or larger than the radius on which the rear end of the next outer fin is located. Thus grain moved inwardly by the outer fin is contacted by the inner fin.
