The invention relates to contribute to the economy of Railways, in particular to the means of mechanization of cleaning ballast from contaminants directly in the path.

Known machines cleaning contaminated ballast with the laying of cleaned ballast in the path where the applied centrifugal method proposed by A. I. Dragacevo-C^), which proved to be a high performance technique that allows you to withdraw up to 200 workers at an estimated annual volume of work (C. A. Solomon. Machines and mechanisms for track facilities. M.: Transport, 1984, S. 223).

Long-standing practice of using the techniques revealed the following deficiencies. Low quality of treatment, i.e., purified these machines ballast not completely liberated from the pollutants, and the head of the expensive element of the cleaning mechanism - mesh tape due to high speed of its movement along a complex trajectory and the significant abrasiveness ballast quickly fails.

Cause defective cleaning of the ballast is the following circumstance. Cut the layer of contaminated ballast thickness of the order of 400 mm is fed to the endless mesh belt, accelerates to a speed of 12-14 m/s and on a curved trajectory in a split second under the action of centrifugal force must be free from contaminants and those grains that are smaller than the cell size of the mesh tape. A significant portion of the pollutant is "sandwiched" in the thickness of the ballast using the same centrifugal force, which results to get the desired quality clear tatou tape. However, in this case several times decreases the performance of the machine, which leads to the need to increase several times the duration of the "window" (the closing time of driving).

Closest to the technical nature of the proposed technical solution is subpotential machine SOM-Cy(C. A. Solomon. Machines and mechanisms for track facilities. M.: Transport, 1984, S. 254), consisting of a welded frame, supported by two self-propelled trucks, pit device, webpotential.com mechanism, the hopper valve, two conveyors for removal of pollutants from webpotential.com mechanism, dosing and motor-generators. SOM-Cyadopted as a prototype, compared with other machines of the same purpose and principle of operation has the following advantages - samohodnoy and the ability to clean contaminated ballast without lifting limit of the lattice, which is achieved by equipping this machine pit device, which can be omitted at the ends of the rails or bars, make the horizontal part of the pit chains under directional grid and produce their cut of contaminated ballast with feeding it on a mesh tape, the trajectory of the cost in a single pass of the machine to clean the prism ballast to the desired depth, about 400 mm, and obtain the desired quality of cleaning is not possible for reasons which are common to all SOM operating on a centrifugal method, when a significant portion of the pollutants do not have time to penetrate through the thickness of the ballast layer on the mesh tape to the surface. Another disadvantage is the rapid wear expensive tape.

The invention is directed to the solution of the technical problem to obtain self-propelled webpagetitle machine, which in a single pass cut would be contaminated ballast to any desired depth, were completely removed contaminants and could develop working speed only depending on the traction machine traction wheels with the rails.

The problem is solved as follows.

In webpagetitle machine containing welded frame, supported by two self-propelled trucks, pit device, a conveyor for the removal of pollutants beyond the path, a hopper dispenser and dispenser cleaned ballast, the mechanism of purification of polluted ballast made in the form of batteries installed in series to each other and interconnected chain gears with different gear ratios conveyors with Saether installed pendulum rink, consisting of frame, one end of which is articulated to the frame of the machine, and the other lattice equipped with drive roller at a peripheral speed higher speed net tape of the corresponding conveyor. Under the carrying each branch conveyor in contact with slatted roller, installed thrust rollers, and the length of each lattice roller and thrust vibracall the same and equal to the active width of the corresponding mesh tape. In addition, the machine is equipped with gear conveyor, a receiving portion which is opened in the pit device, and an outstanding part is installed on the receiving end of the first conveyor battery.

This embodiment of the machine guarantees the required quality of purification of polluted ballast allows you to assign the working speed of the machine based on the traction ability of the machine, only the traction wheels with the rail and can significantly increase the service life of the expensive mesh tape, which in this embodiment operates in a much more easy mode.

In Fig. 1 shows a side view of the machine; Fig. 2 - section a-a in Fig. 1; Fig. 3 - section b-B in Fig.2.

The machine has a welded frame 1, supported by two self-propelled truck 2, and napolnennyy in the form of a battery installed in series and connected to each other by a chain transmission 5 of the conveyor 6 with mesh tape 7, working from a common drive (not shown), and the first conveyor her foster-end brought under outstanding end of the conveyor 4, and permitting the end of the last conveyor 6 is displayed in the hopper dispenser 8; pendulum rollers 9 mounted above the conveyors 6, each of which represents a frame 10, one end of which is pivotally mounted on frame 1, and the other (free) feature driven lattice roller 11, the receiving rotation by means of a chain 12 from the actuator 13 mounted on the frame 1; the persistent compaction rollers 14, mounted on the frame 1 beneath the work each branch conveyor 6 at the site of contact lattice roller 11 with the tape 7; pick the conveyor 15, is installed under the battery conveyors 6; transverse conveyor conveyor 16 mounted under the outstanding end of the conveyor 15; and a dispenser 17.

Subpotential machine operates as follows.

The position of the pit device 3 is introduced into the prism ballast are included in the work transfer conveyor 4, the battery of the conveyors 6, pick conveyor 15, conveyor conveyor 16 and the oscillating rollers 9, then the car starts to move.

Cut the layer of ballast using pit oestrogenes the process of cleaning the ballast, which looks like this. Since the speed of movement of the mesh belt of the first conveyor 6 more speed conveyor belt 4, the cross-sectional area of the ballast on the conveyor belt 6, in comparison with the cross-sectional area of the ballast on the conveyor 4, there will be less by an amount directly proportional to the difference of their velocities. The same phenomenon will take place when considering the transfer of ballast from the first conveyor 6 on the second and so on until the last pair of conveyors in the battery, since the belt speed of each conveyor is greater than the speed of the previous one, which is achieved when the total drive battery (not shown) due to the different gear ratio chain transmission 5. It is envisaged that the net tape, past the carousel at the battery must have the same speed at which the cross-sectional area of the layer of ballast on it will be equal or close to the value F=B, cm2where In the active width of the conveyor belt; - the maximum size of a grain structure for this section of the route, approximately 6 cm (Reference road and brigade road. M.: Transport, 1986, S. 132, so 3.34). Under such conditions, pollutants, practically, nothing prevents to pass netted flax is m plot batteries fosters the pendulum rollers 9, "Ted" passing underneath the layer of ballast, and their work together with persistent webacademy 14 razmarivaet lumps of cemented particles of ballast that can be transferred to the conveyors of the battery. In addition, there is more mixing of ballast dropping it from one conveyor to another. The cleaned ballast from the last conveyor 6 is discharged into the hopper of the distributor 8 and later in the path, where they engaged in the dispenser 17. Contaminants and fines sifted through mesh tape 7 of the conveyor 6, get to pick the conveyor 15 and served them on the transverse conveyor conveyor 16, with which the screenings are removed outside the path.
