Description

f The invention relates to a device for hopper-dispensers for dosed filling of ballast on a railway track during its construction, repairs and can also be used in the construction of wagons intended for the transportation of bulk cargoes. A known hopper containing a frame supported by running bogies, a hopper mounted on the frame with unloading hatches having covers and a ballast dispenser with lateral, transverse and nadral beams to which ballast dividers are fixed (RU 2171755 C1 7 B 61 D 7/02, E 01 B 27/02). A known hopper containing a frame supported by running trolleys, a hopper mounted on the frame with internal and external discharge hatches and a mounted dispenser with longitudinal screens in the form of streamlined planes located above the rails to protect them from ballast during unloading (ed. St. USSR No. 99961, class E 02 В 27/02, 1951) In these hopper cars, devices for opening and closing the covers of unloading hatches have a large number of rods and levers and require a lot of time to maintain the car and bring it to Tranfer position. 3105665 200 O .... „.

The technical result of the invention is to facilitate the installation and maintenance of the car and reduce the time for putting it into the transport position, simplifying the design of the dispensing and dosing mechanism and the car as a whole.

To achieve a technical result, in a hopper dispenser comprising a frame supported by a trolley, to the lower part of which is attached a hopper with unloading hatches located along the axis of the car and a ballast dispenser with the possibility of height adjustment by a drive consisting of side and transverse beams, covers are installed, covering the unloading hatch and serving at the same time as over-rail shields, providing protection of the rails against ballast. Moreover, the covers are attached to the dispenser and are over-rails of the dispenser. The design of the car, thus significantly simplified, since the roofs, perform with their main function - overlapping unloading hatches, the function of protecting the rails from falling asleep with ballast. The number of unloading hatches 2 and they are located above the rails.

In FIG. 1 shows a diagram of the dispensing and dispensing mechanism of the hopper dispenser with the covers of the unloading hatches closed (transport position).

In Fig.2 the same with the open covers of the unloading hatches (working position).

A hopper-dispenser, comprising a frame 1 supported by a trolley, on which a hopper 2 with unloading hatches is mounted, each of which can discharge ballast on both sides of the longitudinal axis of the rail, ballast dispenser 3 mounted in the lower part of the frame with the possibility of height-adjustable drive and fixing it in a certain position with

simultaneous opening or closing of the hopper discharge hatches.

The dispenser 3 consists of two side beams, interconnected by two end (transverse) beams, to which their ends are attached a cover 4, made in the form of a nadrels a protective screen that prevents the ballast from getting on the rails during unloading and located below the opening of the unloading hatch of the hopper 2. Cover 4 is a gable angle, the apex of which is directed upward. In the transport position, the dispenser 3 is raised and is located below the hopper so that the discharge cover 4 partially enters the lower part of the hopper, blocking with its planes the opening of the discharge hatch. When lowering the dispenser 3 into the transport position, the unloading cover 4 together with the dispenser goes down, opens the opening of the unloading hatch and at the same time closes the rails from falling asleep with ballast. Ballast from the hopper falls on the slopes of the cover 4 and then laid on the track grid. To stop the process of unloading the ballast, it is necessary to raise the dispenser 3 into the transport position, the wing 4 will block the opening of the unloading hatch of the hopper 2 and the unloading process will stop.

In the transport position, cover 4 completely covers the opening of the discharge hatch (closed position of the cover).

Thus, the combination of the cover with the overhang beam of the dispenser makes it possible to significantly simplify the design of the car and the loading and dispensing mechanism of the hopper dispenser, and to increase the reliability of its operation.
