Abstract

The invention relates to a device for cleaning a railroad ballast composition. The purpose of the invention is to increase efficiency by uniformly loading the cleaning screen. The rubble, initially cleaned by the cleaning grid 9, flows onto the upper side of the inclined shield 3, rolls over it, enters the holes 4 and is poured back through them to the free part of the grid 9. Opening of the holes 4 is achieved by moving the plate 5 by the drive 10 along the guides 6. Thus, on the grid 9, the initially cleaned crushed stone is re-cleaned. By adjusting the position of the plate, better cleaning of heavily soiled or wet rubble is achieved, il hp f-ly, 2 ill. with s

The invention relates to devices for cleaning the track jiacTa ball track composition, I The purpose of the invention is to improve efficiency by uniformly loading the cleaning screen.

Fig, 1 shows the device, a general view; FIG. 2 is a view A of FIG. 1,

The device for cleaning rubble of the railway track consists of frame 1, cutting knife 2, inclined shield 3 with holes 4, plate 5, guides 6, deflecting rollers 7, brackets 8, cleaning grid 9, drive 10, driving stars P and strips 12,

The guides 6 are two L-shaped profiles, the vertical shelves of which are rigidly fixed to the Lower side of the inclined shield 3 and Oriented to the inclined search 3 Longitudinally perpendicular to the movement of the cleaning grid 9, the Plate 5 Nirno ball in the upper part is connected to the actuator 10, rigidly fixed on the top of the non-working side on the jcrioHHoro xit 3 over the guides 6, in the upper part of the plate 5 along its edges in the zone of its inlet into the guides 6 there are bars 12 that serve as a limiter for lowering the plate 5 by the drive 10 and The role of safety elements in case of failure of the drive 10, i.e., prevent the penetration of the plate 5 onto the cleaning screen 9 yr and its separation from the drive 10. The size of the holes in the inclined shield is made larger than the size of the normal fraction of crushed stone freely passed through the holes 4.

placed stepwise, the height Y, the placement of the holes 4 at the zone of weeds removal is the most crushed stone itself, in the last stage of placement of the holes 4 the height U is the smallest, and the distance from the holes 4 is increased

It goes from b to b 1 from the weed ejection zone. The placement of the holes 4 is thus necessary, since in the outermost part of the cleaning grid 9 the layer of initially cleaned crushed stone is the smallest (the ordinate of the holes 4 is the smallest), and as the cleaning grid 9 moves along the knife, the layer of initially cleaned increases

rubble, so in the lifting zone of the cleaning grid 9 (in the zone of weeds emission) the ordinate of the holes 4 is the greatest, and the distance between the holes is the greatest flow of cleaned Peterbn from the cleaning grid 9 to the inclined shield 3 near the weedy emission zone, therefore it is in this the zone should have the largest number of holes 4,

The device works as follows.

The contaminated ballast is cut by the knife 2 and enters the cleaning grid 9, in the lifting zone its weeds are removed from the rubble, and it rises up and in the bend zone of the cleaning grid 9 is dumped onto the inclined shield 3, Part of the weeds falls on the cleaning grid 9, where together with the rubble being cleaned, they are further purified. Purified rubble, rolled from the sloping seeker 3, is on its way back

When working on heavily clogged areas or when wet rubble is driven by i O along the guides 6, the plate 5 moves to the upper position. At the same time, the openings 4 are opened and the initially cleaned crushed stone falls onto the cleaning grid 9 in its distant part and is additionally cleaned,

Claims (2)

Invention Formula 1, A device for cleaning rubble of a railroad track, comprising a frame on which a cutting knife is placed, a cleaning grid and an inclined shield located therein with openings, characterized in that, in order to increase efficiency by uniformly loading the cleaning grid, it is equipped with a blocking device sloping shield holes, consisting of a drive-connected plate mounted for movement in directions, which are fixed on the non-working side of the said shield. 2. A device according to claim 1, characterized in that said apertures of the inclined shield are spaced apart with an increase in the distance between them in the horizontal direction and with a decrease in the level in the direction opposite to the discharge zone from the specified weed grid.
