The invention relates to railway transport, namely to track machines for processing ballast without removing the track grid.

The purpose of the invention is to improve the efficiency of the machine by improving the quality of cleaning rubble.

On the FLG, 1 shows a machine, a general view; figure 2 is a section aa in FIG.

On frame 1, a scoring knife 2 is mounted, feeding crushed stone cut out from under the elevator by means of mechanism 3 for raising the rail-sleeper grid onto an endless transporting belt A, and then onto a mesh belt Z.Trans-sporting belt 4p is positioned transversely to the longitudinal axis of the machine and passes above the cutting knife 2, moving in its guides, and has an I drive 6 located in the upper part of the frame t.

 In the center of the frame along the longitudinal I axis of the machine there is an infinite I mesh: tape 5, missed inside; When transporting the belt 4, it moves in the curved guides I and is driven by the electric drive I 7.

I B the result of the mutually perpendicular arrangement of the transport 4 and the net 5 belts grow; the reliability of the entire cleaning device, the possibility of selecting contaminants is ensured, the quality of cleaning is improved due to the full use of the width of the mesh tape 5, d— To receive contaminants from the purification device on the frame 1 — I set the conveyor 8, a –– for loading their rolling stock - turning conveyor 9.

In the bend zone of the mesh tape 5, the cleaned crushed stone enters the bunker 10, which distributes it on the way or on the conveyor 11 to the bunker-drive 12 in case of over-lifting of the path.

In order to evenly distribute on the cleaning mesh belt 5, cut out rubble is installed on the frame 1 an inclined switchboard 13 which is adjustable at different angles.

The machine works as follows. zom.

When the machine is moving, the cutting knife 2, mounted on frame 1, recessed into the ballast prism, while raised with the help of mechanism 3, lifts the rail and tie bars, is cut off

a layer of contaminated rubble. Moving along the scoring knife 2, the rubble enters the horizontal section of the conveyor belt 4 and under the action of centrifugal force moves up the belt upwards, where in the bend zone it is detached from the belt and under the influence of inertia forces falls into a switchboard 13 for uniform

the distribution of rubble across the width of the mesh tape 5 installed along the longitudinal axis of the machine. Under the action of centrifugal force, the crushed stone is cleared of dirt and when the curved section passes through the curved section, the crushed stone is dumped into the bunker 10, distributed into the path, and with an excess of it (in the case of over-lifting the path) it is directed to the conveyor 11 and further to the bunker-accumulator 12.

Weeds separated from rubble are thrown out by centrifugal force through the mesh of the mesh belt 5 onto the conveyor 8 and further onto the turntable.

conveyor 9 for loading into rolling stock.
