<p>The invention relates to a hydraulic percussion hammer for binding dust spreading during breaking work from the material to be broken to the surroundings. According to the invention, the hydraulic percussion hammer (1, 11) comprises at least one conduit (5, 15) for dust-binding agent connected to the hammer in such a way that in order to spray the dust-binding agent onto the target (4, 14) to be broken, the conduit (5, 15) for dust-binding agent is connected from one end to a tank (6, 18) for dust-binding agent, comprising an associated pumping means (7, 16) for supplying the dust-binding agent with high pressure to the conduit (5, 15) for dust-binding agent. Furthermore, at least one nozzle (8, 23) is attached to the opposite end of the conduit (5, 15) for dust-binding agent in order to direct the spray of dust-binding agent at least partly at the target (4, 14) to be broken around the tool (9, 21) of the hydraulic percussion hammer.</p> |
