CONSTRUCTION APPARATUS FOR PROJECTION TRAFFIC SIGNAL ON ROAD

摘要

PURPOSE: A construction machine for projecting a lane mark is provided to improve workability by constructing a lane projecting on a road with a bonding method and to efficiently prevent foreign substances from being dropped by shielding a discharge hole after discharging the paints. CONSTITUTION: A construction machine(100) for projecting lane mark comprises a hopper(110), a paints supply unit(120), an uneven part generation unit(130), a shield device(140), and a bead spray unit(150). An upper part of the hopper is opened in order to draw paints. The inside of the paints supply unit is connected to each other in order to draw the paints and the paints drawn to the inside is transferred for supply. The uneven part generation unit is connected to one side of the paints supply unit and includes a plurality of discharge holes. The shield device reciprocates from side to side in the lower side of the uneven part generation unit and blocks the exposure of the discharge holes to the road after discharging a predetermined amount of paints through the discharge hole. The bead spray unit is fixed on one side of the paints supply unit and coats the glass beads by spraying the glass beads towards the uneven parts generated on the road.
