Definitions

  • the invention relates to a screening machine with a large number of cross members (2, 4) arranged transversely to the direction of the material to be conveyed, on or between which a flexible screen covering (13) is fastened, the cross members moving relative to one another by at least two movement systems (I, II) are driven that mutually adjacent cross beams alternately approach and move away from one another, the cross beams (2, 4) being in separate, mutually parallel planes (14) in which the cross beams each have a movement system.
  • the object of the invention is to improve a screening machine of the type mentioned in such a way that the strokes of the movement systems are largely independent of their masses.
  • each movement system is movably attached to a base frame arranged below it.
  • the first inner movement system 1 has two cheeks 1 made of U-shaped profiles, between which cross members 2 are fastened parallel to one another at regular intervals. Outside of the cheeks 1 are cheeks 3 of a second external movement system II parallel to the inner cheeks 1 and cantilever cross members 4, which are arranged centrally between the cross members 2 at the same height.
  • the cross members 2, 4 thus alternate with one another and carry on their upper side a screen covering 13 which is fastened in a line to the cross members.
  • the inner cheeks 1 are movably supported by at least four pairs of link springs 7 or articulated supports on the machine base frame 20, which stands on the floor via spring elements 19.
  • the outer cheeks 3 are movably mounted on the base frame via separate springs 7, all the springs being parallel to one another.
  • Outside of the cheek 1 can protrude tube support 8, which serve as a bearing for the springs 7.
  • the rods or springs 7 are arranged obliquely, in particular at an angle ⁇ of 45 degrees, to the sieve plane or to the planes in which the cross members lie.
  • a drive shaft actuated by an electric motor 22 le 9 mounted with at least two eccentrics 10a, 10b, the eccentric pushing rods 11a, 11b, the ends of which are opposite the eccentrics and are attached to the cheeks 1, 3 via projecting arms 12.
  • the push rods 11a, 11b are at right angles to the rods or springs 7. A particularly uniform drive is achieved when both side cheeks 1, 3 are driven by a push rod in both systems.
