WASHING ATTACHMENTS Russian patent published in 2024 - IPC E01H3/02 E01H1/00 

FIELD: machine building.

SUBSTANCE: invention relates to vehicles for cleaning roads and streets, in particular to design of washing attachments, which is used as part of a combined road machine for washing noise protection screens, tunnels, road conditions, road signs, information boards, etc. Wash attachment is made with possibility of detachable installation on road machine (20) and contains articulated main lever (3), middle lever (6) and end lever (10). At least one comb (14) with nozzles (16) is hinged on end lever (10). Wash attachment comprises attachment frame (1), which enables its installation on road machine (20). Main lever (3) is pivotally mounted on attachment frame (1) by means of rotary lever (2), which provides possibility of rotation of main lever (3) in vertical and horizontal planes by means of hydraulic cylinders (7, 12), which by one of their ends are pivotally mounted on rotary lever (2), and by the other ends—on main lever (3) and attachment frame (1), respectively. Middle lever (6) is connected to main lever (3) by means of hinged joint (5), which provides rotation of middle lever (3) in vertical plane by means of hydraulic cylinder (8), which by one end is pivotally connected to main lever (3), and by the second one—to hinged joint (5); end lever (10) is connected to middle lever (6) by means of hinged joint (9), which provides rotation of end lever in vertical plane by means of hydraulic cylinder (11), which by one end is pivotally connected to middle lever (3), and by the second—to hinged joint (9). At least one comb (14) is installed on end lever (10) by means of rotation drive (13).

EFFECT: providing a lightweight hinged structure of washing equipment, which can be used for operation on both sides of the vehicle and removed from it, as well as increasing its durability.
