SWEEPER Russian patent published in 1995 - IPC

FIELD: machines for cleaning motor roads and side-walks from snow. SUBSTANCE: machine has base chassis 1, brush 6 mounted on frame 3 square to longitudinal axis of base chassis and brush hair deflectors 9 mounted on frame 3 at angle β in horizontal plane relative to axis of rotation of brush 6. Ends of deflectors 9 are arranged inside hair rotation circumference and are mounted on frame 3 by means of levers 10 which are connected with lower ends of frame bracket 12 by cylindrical joints 11. Upper ends of brackets 12 are connected with frame 3 by joints 13 and are spring- loaded relative to frame 3. Change of angle a of deflectors 9 in vertical plane provides phase shift of moment of loss of contact between hair and deflectors 9 according to turning angle of brush 6 and change in direction of throwing away of snow relative to machine longitudinal axis. EFFECT: enlarged operating capabilities, enhanced quality of road cleaning. 2 cl, 4 dwg
