Abstract

The utility model provides a binding impact hammer with rotating device, which binds small-diameter impact hammer into large-diameter impact hammer. The utility model comprises a central impact hammer inside the hammer casing along the axis and at least 5 small vertical impact hammers uniformly arranged in a circumference of the outer layer of the hammer casing. The rotating device comprises a rotating body with connecting flanges at both ends, a rotating arm and a fixing sleeve which are arranged in a square casing, and the square casing is provided with a pair of cylinders for driving the rotating arm. The binding impact hammer of the utility model changes impact point continually, and the rotation of the impact hammer is not started by a power head, thus avoiding power head motor damage resulting from frequent starting. The impact hammer breaks rock at a rate of 10-12 cm/min, while the cost is just one tenth of oversea cost, and the utility model can directly impact the slightly-weathered and non-weathered rock above 100Mpa.
