Description

 The invention relates to devices for the construction and repair of railway tracks and can be used for transporting ballast and ballasting of the railway track.

 A known hopper dispenser comprising a frame supported by running trolleys, a hopper mounted on the frame with internal and external discharge hatches having covers, a ballast dispenser made with over-rails and mounted in the lower part of the frame with the possibility of height adjustment by a drive, and a restriction screen ballast filling, installed in the lower middle part of the dispenser with the possibility of fixing in the upper position (RU 2105834 C1, E 01 B 27/02, 02.27.98).

 Known hopper dispenser comprising a frame supported by a trolley, a hopper mounted on the frame with internal and external discharge hatches having covers, a ballast dispenser installed in the lower part of the frame with the possibility of height-adjustable drive (RU 2049840 C1, E 01 B 27/02 , 12/10/95).

 In well-known hopper batchers, interruption of ballast unloading from the hopper batcher is not provided during its operation; the covers of their discharge hatches can only be closed with the hopper batcher completely unloaded.

 The technical result of the invention is the provision of interruption of unloading of ballast from a hopper dispenser at any necessary moment of its operation and resumption of unloading of ballast from it also at any necessary moment of operation of a hopper dispenser.

 To achieve this technical result, in a hopper dispenser containing a frame supported by a trolley, a hopper mounted on the frame with internal and external discharge hatches with covers, a ballast dispenser mounted in the lower part of the frame with a height-adjustable drive, the covers are single-jawed and fixed on shafts connected to the pneumatic cylinders using levers and located along the hopper dispenser inside the hopper, and the covers are fixed with the possibility of rotation by the said shafts across the hopper doses atora.

 In addition, the shafts are mounted on the front and rear walls of the hopper using spherical bearings, and the covers of the unloading hatches are mounted on the shafts with dowels, and each cover of the unloading hatch is single-jawed and consists of a shell in the form of a part of the angular sector of the cylinder directed convex surface downward, and two cheeks attached to both ends of the concave surface of the shell, and in the upper part of each cheek there is a sleeve with a cylindrical hole and keyways for connecting to the corresponding shaft.

 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 covers of the unloading hatches open (working position). In FIG. 3 is a section AA in FIG. 1. In FIG. 4 - unloading hatch cover. In FIG. 5 is a section BB in FIG. 1.

 The hopper dispenser contains a frame 1, which is supported by running trolleys. In the lower part of the frame 1, the dispenser 2 is installed with the possibility of shifting in height by a predetermined amount by the drive. In the middle lower part of the dispenser 2 there is a screen 4 for restricting filling the middle of the track with ballast with a gable longitudinal beam. The hopper 3 is mounted on the frame 1 and is made with external and internal discharge hatches, respectively having covers 5 and 6, mounted on the shafts 7, which are connected by levers 9 to the pneumatic cylinders 8. The shafts 7 are located along the hopper batcher inside the hopper 3 and are attached to its front and the rear walls using two self-aligning (spherical) bearings 11. The free end (protruding from the hopper 3 end) of each shaft 7 is fixed in the lower part of the frame 1 on the transverse beam using a third self-aligning (spherical) bearing Ika 11, and this end of the shaft 7 is connected to the corresponding lever 9, pivotally connected to the pneumatic cylinder 8, which is mounted on the beam of the body 10. The part of the shaft 7 located inside the hopper 3 is protected from the influence of the load (crushed stone, ballast) by a casing, for example, this part of the shaft 7 is placed in the pipe.

 On each shaft 7, by means of dowels 12, a cover 5 or 6 of the unloading hatch is fixed with the possibility of rotation with the corresponding shaft 7 across the hopper dispenser.

 The covers of the external 5 and internal 6 unloading hatches are single-jawed and are in section a corner sector of the circle that rotates relative to the center. Each cover of unloading hatches consists of a shell 13 in the form of a part of the angular sector of the cylinder, a convex surface of the sector directed downwards, and two cheeks 14 attached to both ends of the concave surface of the shell 13, for example, by bolted joints. In the upper part of each cheek 14, a sleeve 15 is installed with a cylindrical hole and keyways for connecting to the shaft 7. The axis of the hole of the sleeve 15 is parallel to the generatrix of the shell 13 of the cylinder segment and is the center of the radius of the shell 13.

 When unloading ballast from a hopper batcher, the rod of the pneumatic cylinder 8 leaves the cylinder body and rotates the lever 9 with the shaft 7 and the cover 5 or 6 at a certain angle, opening the opening of the discharge hatch. To stop the process of unloading ballast from the hopper metering rod of the pneumatic cylinder 8 enters the cylinder body and rotates the lever 9 with the shaft 7 and the cover 5 or 6 to its original position. The lid 5 or 6, dissecting the edge of the shell 13 of the ballast flow, blocks the opening of the discharge hatch.

 Installing on the discharge hatch of the hopper 3 of a single-jaw lid 5 or 6, opening across the hopper dispenser and mounted on a rotary shaft 7 located along the hopper dispenser, allows intermittent ballast unloading from the hopper dispenser.
