The invention relates to the construction engineering, in particular to drum roller cleaning devices, and may be applied in pavement leveling and compacting machines.The drum (1) roller cleaning device comprises a toothed track (2) made on the inner end surface of the drum (1) ferrule. On a hood (3) are fixed two telescopic hydraulic/pneumatic cylinders (4), (5). At the free end of the hydraulic/pneumatic cylinder (4) on a rotating axle with a pulley is fixed a gearwheel (6). On a rotating axle with a pulley (7) is installed a single-arm lever (8), connected to the free end of the hydraulic/pneumatic cylinder (5). At the free end of the lever (8) is installed a rotating axle with a pulley (9), on which is mounted a cylindrical brush (10). The pulleys are connected by endless flexible members (11), for example a chain.The technical result consists in the possibility of adjusting the gap between the brush and the roller, actuating the device only when needed, which increases its service life. |
