Definitions

  • the invention relates to a screening machine with a plurality of parallel cross-members arranged in parallel and at intervals, between which flexible screen linings are fastened and of which every second cross-member moves relative to the other intermediate second cross-members in order to alternately stretch and compress the screen linings, all of which Cross beams are moved in a circle by an imbalance.
  • the object of the invention is to improve a screening machine of the type mentioned in such a way that it is structurally simple and achieves high screening performance.
  • the structurally very simple unbalance drive takes over the movement of the second crossbeams in between, so that a movable bearing is only required for the directly driven crossbeams.
  • the other cross members can be fastened to machine parts, in particular to the screen box, which is moved by the eccentric.
  • Construction and drive are particularly simplified if the imbalance is attached to a shaft that drives the first crossbeam with at least one eccentric. It is preferably proposed that the shaft be mounted in the machine parts, in particular the screen box, to which the second cross members are attached.
  • the screening machine has a screen box with two side cheeks 1, 2, which run perpendicular and parallel to one another and between which the cross members 3, 4 are at right angles. While the first cross members 3 are rotatably mounted on the side cheeks, the second cross members 4 located therebetween are immovably fixed on the side cheeks 1, 2. The first and second cross members 3, 4 alternate with each other, so that when the first cross member 3 swings back and forth, the flexible screen mats 5 located above the cross members 3, 4 are alternately stretched and compressed.
  • the drive axis of the first cross member 3 are inserted through both side cheeks 1, 2 and fastened there to rocker arms 6 which are essentially vertical and are fastened with their upper sides to a coupling rod 7.
  • the coupling rod is in turn connected via a joint rod to a ring element 9 which is fastened on an eccentric 10 .
  • the eccentric 10 sits on a shaft 11 which is driven by an electric motor 13 via a gear 12.
  • the electric motor 13 thus generates a regular swiveling back and forth of the cross members 3 about their longitudinal axes via the aforementioned members.
  • the shaft 11 with the two end-side eccentrics 10 is approximately in the center of gravity the machine arranged parallel to the cross beams, so that on both sides of the shaft 11 and the eccentric 10 joint rods 8 and coupling rods 7 are arranged, with a coupling rod 7 one half of the cross beams 3 and the other opposite horizontal coupling rod 7 the other half of the cross beams 3 drives via rocker arm 6.
  • Sector-shaped unbalance elements 14 are fastened on the shaft 11, which is rotatably mounted in the side cheeks 1, 2, on both outer sides of the side cheeks 1, 2, which are rotationally adjustable with respect to the shaft and thus also the eccentrics 10.
  • these unbalance elements 14, both of which are set at the same angle and thus parallel to one another, the entire screen box is set in vibration.
  • the underside of the screen box or the undersides of both side cheeks 1, 2 are placed on elastic bearings 15, in particular spring elements.
  • the cross members 4 are placed in circular vibrations exactly or approximated, which also superimpose the oscillating movements of the cross members 3, since these cross members 3 are also exposed to the circular vibrations. This not only improves the screening performance and transport of the material to be screened, it also increases self-cleaning.
  • the supports 4 located in between can also be driven in a tilting manner by a second tilting drive.
  • eccentrics can be attached to the shaft of the second tilt drive.
  • FIGS. 3 and 4 differs from that according to FIGS. 1 and 2 in that the cross members 3 are connected to one another by lateral bars 16 are connected, which move parallel to the longitudinal direction of the screening machine with respect to the side walls.
  • the spars 16 rest on vertical links 17.
  • these reciprocating links 17 can also be inclined relative to the spars in order to additionally support the transport of the material to be screened.
  • the screening machine is also possible to design the screening machine as a double deck, i.e. Arrange and drive two screen surfaces with the first and second cross members in parallel one above the other.
  • a second screen deck can also be fastened over the driven screen deck according to FIG. 1 or FIG. 3, the cross member of which is driven only via the unbalance and which serves as a protective deck with larger opening widths.
