MACHINE FOR DISTRIBUTION OF RAIL TRACK BALLAST Russian patent published in 2010 - IPC E01B27/02 E01B27/00 

FIELD: construction, road engineering.

SUBSTANCE: invention relates to devices for construction and repair of rail track, in particular to devices for distribution of rail track ballast. Machine for distribution of rail stock ballast comprises frame that rests on carrier. Frame comprises the following components mounted on it - power device, operator's cabin, ballast pickup, tunnel-shaped plates for protection of rails, shields for distribution of ballast between rails installed with the possibility of lifting and lowering by means of hydraulic cylinders, side ploughshares installed with the possibility of rotation by means of hydraulic cylinders, wings, additional frame connected to machine frame by means of traction rods and lifting hydraulic cylinders. In lower part of tunnel-shaped plates there are rollers fixed with flanges for installation of additional frame onto rails of track. Box-like beams are installed on central beam of additional frame with the help of vertical axis. Shields for distribution of ballast between rails are installed on box-like beams. On each box-like beam there is a bracket fixed, where a boom is installed made of two parts. Beam, where side ploughshare is fixed, is connected to boom.

EFFECT: invention provides for accurate profiling of ballast prisms and provision of various profiles of ballast prisms for all classes of rail roads as machine moves in both directions, including curved sections of small radius path.
