UNIVERSAL SWEEPING MACHINE Russian patent published in 2017 - IPC E01H1/08 E01H5/10 

FIELD: transportation.

SUBSTANCE: universal sweeping machine comprises a gas flow generator, a suction vortex chamber made in the form of concentrically disposed shells, a hopper for collecting moisture and sweepings, the cavity of which communicates by the channel with the vortex chamber, and a channel disposed between the walls of the housing and the hopper, having a butt slot directed onto the surface and intended for feeding water, all of them being placed in the housing on chassis. The machine also includes an annular gas manifold installed around the housing and enveloping the hopper, and a means for gas flow supply, directed under the hopper bottom onto the surface to be treated at an angle thereto and toward its center. The inner vortex chamber shell is made in the form of a truncated cone, the base of which is directed toward the surface to be treated. The gas manifold is divided by a mesh into the upper and the lower cavities, and the means for gas flow supply to the surface to be treated is made in the form of radially arranged nozzles installed in the lower manifold cavity, whose axes are displaced relative to the center of the surface to be treated on 12°-14°. An additional annular channel with a butt slot directed toward the surface to be treated and perpendicular to the latter is made between the walls of the housing and the annular manifold. The machine is equipped with infrared radiators placed in the additional annular channel, the front and the rear movable flaps enveloping the gas manifold and mounted parallel to the surface to be treated, with the possibility to move towards the latter, as well as the vortex flow reflector made in the form of an inverted cup mounted between the vortex chamber and the hopper and forming an annular slot with the vortex chamber.

EFFECT: increased productivity and cleaning quality.
