WASHING-POLISHING MACHINE Russian patent published in 1994 - IPC

FIELD: maintenance of roads and city areas. SUBSTANCE: washing-polishing machine has basic car 1 with tank 2 and water manifold 3 with injectors. The manifold is mounted at an angle in horizontal plane to longitudinal axis of the machine. Rubber lamellar reflectors are mounted ahead the water manifold 3 close to its fore end. Reflectors 12 are mounted onto arms 13 at an acute angle to water manifold 3 in horizontal plane; the reflectors form expansions of water shaft 11. Angle of mounting of the reflectors is directed to the side of back end of manifold 3, this angle is lesser than angle of mounting of the manifold in horizontal plane. Arms 13 of reflectors 12 are mounted on hinges onto the manifold for rotation in vertical plane and are spring-loaded in relation of manifold 3. Reflectors 12 are mounted with their lower end onto the surface of the road. EFFECT: improved efficiency of maintenance. 3 cl, 3 dwg
