Definitions

  • the present invention relates to the field of screening of elements of large particle size in riprap stations, and relates to vibrating bars for such stations.
  • known rip-rap stations are generally provided with parallel trapezoidal static bars, onto which is poured a quarry product of large grain size, which is screened to the dimensions required for its use.
  • Static bars of various shapes and sizes used to date have the drawback of not making it possible to avoid dowelling of large particle sizes and therefore the drawback of thus hindering the correct operation of the riprap stations.
  • the object of the present invention is to overcome this drawback.
  • bars for armourstone station characterized in that they are in the form of a box of large sheet metal pre sensing a trapezoidal longitudinal section, and are inclined relative to the horizontal from the long side to the short side, their cross section being in the shape of a roof, in that they are each provided with one, preferably two motorcycle groups -vibrators giving them a vibratory movement with vertical acceleration, and in that they are mounted on elastic elements.
  • the bar for riprap station is in the form of a box 1 of large sheet metal, which has a longitudinal trapezoidal section ( Figure 2).
  • a bar is inclined relative to the horizontal, from the long side to the short side, its cross section is in the shape of a roof, and it is provided with two motor-vibrator groups 2 which give it a vibratory movement with vertical acceleration. , which is made possible by mounting the box 1 on elastic elements 3.
  • the elastic elements 3 are advantageously rubber blocks mounted on pillars 4 for fixing to the structure of the riprap station and fixed inside the upper part of the box 1 by means of crosspieces 5.
  • the motor-vibrator groups 2 are mounted inside the box 1, advantageously forming a working angle with the roof 1 'of the latter of approximately 30 °, and are provided with unbalanced flywheels whose torque can be varied manually from 0% to 100%.
  • the motors fitted to groups 2 preferably have a power of between 3.2 Kw and 5 Kw, and have a natural frequency of 1000 rpm adjustable by means of a frequency converter between 500 rpm and 1 000 revolutions / minute, so as to obtain a variable unidirectional directed amplitude, preferably between 1.5 mm and 3 mm.
  • the large working angle of the motor-vibrator groups 2 relative to the casing 1 allows advance by vibration of the materials to be treated, the flow speed of which is a function of the slope of the bars and the vertical acceleration of each bar.
  • these vibrating bars are advantageously five in number, and the fact that they are mounted on rubber elements 3 allows the reception of large blocks and the absorption of impacts during dumping by dumpers, or analogues.
  • the opening between bars is widely divergent in order to avoid doweling of the materials, so that their passage between said bars is largely facilitated and that a relatively exact cut of materials is obtained.
