FIELD: railway operation, in particular, equipment for controlling of grass weedage and elimination of brush from road-bed and permanent way.
SUBSTANCE: base platform is mounted by means of vehicle on permanent way portion intended for treatment with herbicides. Before treatment operation, hose sections are moved to working position, i.e., in parallel with surface to be treated. Movable members of housing are set in horizontal position. Water feeding is provided through pipeline from reservoir and preparation is fed through pipeline from tank into mixer. Simultaneously, pump is switched on and flow velocity regulator is moved to position for returning of working fluid through return pipeline into mixer. Converging tube is positioned with its flare portion oriented in direction of treatment. After switching-on pump, spraying apparatus advances along permanent way portion to be treated. Air flow velocity sensor generates signal delivered to flow velocity regulator drive to provide change-over of feeding of working fluid from return pipeline into pressure pipeline, through which working fluid is delivered to sprayers for applying working fluid onto road-way of permanent railway. Increase in the velocity of sprayer results in increase of flow velocity and, correspondingly, increase in an amount of working fluid fed to sprayers. Simultaneously, signal from sensor is delivered to movable member drives providing rotation thereof in vertical plane and defining housing restricting entrainment of drops with vortex air flows. Air is delivered through air duct to openings, from which it is discharged to the outside to thereby facilitate deposition of small droplets created during spraying of working fluid from sprayers. On increase of velocity of spraying apparatus, intensity of deposition of droplets is increased.
