FIELD: railway-transport. SUBSTANCE: invention relates to design of hopper-batcher for metered delivery of ballast at construction, repair and maintenance of tracks and it can be used in cars for carrying loose loads. Proposed hopper-batcher contains frame 1 resting on bogie and hopper 2 with discharge hatches closed by covers and ballast batcher 3, consisting of side, cross and overrail beams, installed in lower part of frame for changing the height by drive. Screens 4 are secured inside hopper whose location relative to opening of discharge hatch regulates getting ballast out of discharge hatch. Width of screen precludes direct pressure of ballast column onto cover. Width of screen is either greater than or equal to width of discharge hatch opening. Screens are made in section in form of angle plates with vertices pointing upwards. Covers are aligned with overrail beams of batcher. EFFECT: improved reliability, simplified design. 4 cl, 6 dwg
