Steering shovel excavator
For a steering shovel excavator, a bucket arm of an existing excavator is divided into an upper bucket arm and a lower bucket arm, the two ends of a connecting shaft are fixed in the middles of the upper bucket arm and the lower bucket arm respectively, and the upper bucket arm and the lower bucket arm are connected into an integral bucket arm. The upper bucket arm is provided with a driving device and a locking device, the upper bucket arm does not rotate, but the upper bucket arm can drive the lower bucket arm to rotate to a proper angle and be locked. According to the steering shovel excavator, the orientation of an opening of a shovel can be changed, excavating can be conducted forwards or towards other directions, and the construction is more convenient. When a bucket is replaced by a breaking hammer to impact on a concrete pavement or a stone, the direction of prying pieces through a drill rod can be changed, prying can be conducted forwards or towards other directions, and especially for working in streets of a city, the excavator can quite conveniently utilize the limited space while avoiding the stream of traffic. When the breaking hammer drill rod impacts on the cement pavement, the excavator can walk on a flat pavement but not on the pieces which are broken by impacting, and it is not necessary to utilize the drill rod to push the pieces for paving. By means of the steering shovel excavator, the work efficiency can be improved, and the construction time can be shortened.
