[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stone-cutting excavator in which a plurality of excavation holes are provided in a row on a stone stone, and the stone stone can be split by the excavation holes.

[0002]

2. Description of the Related Art Conventionally, a rock-cutting excavator drills a large number of drilling holes vertically in a row in a rock, and drives a stone rock along the drilling hole by driving a wedge or the like into the drilling holes. I try to divide it into sizes.

[0003] Such an excavator is mounted on a base or the like which can be installed on a stone bed. When installing on a stone bed, the base is placed on the stone bed and a drill of the excavator is drilled. Drilling holes are drilled on the stone bed by descending vertically while rotating.

[0004]

[Problems to be Solved by the Invention] However, the above-mentioned stone digging excavator has the following problems. That is, the surface of the rock is not necessarily formed horizontally, and therefore, when breaking a rock having an inclined surface, when the base having the excavator is placed, the base also tilts along the surface. The excavator was unable to perform vertical excavation.

[0005]

In the present invention, an excavator holding case is rotatably mounted on an excavator support frame in a front-rear direction, and a suspension frame is mounted on the excavator holding case in a lateral width direction. The present invention provides an excavator for rock splitting, wherein the excavator is rotatably mounted on the suspension frame so as to be rotatable in a horizontal direction.

Further, according to the present invention, a support rail is erected on an upper part of an excavator support frame which is capable of traveling.
Both ends of the rail are rotatably supported, the rail is rotatable around the axis, and an excavator holding case that moves along the rail is provided on the rail,
The suspension frames are suspended from the excavator holding case so as to be tiltable in the direction in which the rails extend, and are lined up at the lower end of the suspension frame in a row with a rotating part that rotates in the horizontal direction. A plurality of excavators are mounted, and the excavators are configured to be rotatable around the axis of the suspension frame.

[0007]

In the present invention, the excavator holding case is rotatably mounted on the excavator support frame in the front-rear direction, and the suspension frame is rotatably mounted on the excavator holding case in the left-right width direction. The excavator is attached to the suspension frame so that it can rotate freely in the horizontal direction, and the position of the excavator can be easily adjusted to form a substantially vertical excavation hole on the stone bed. is there.

[0008] Further, an excavator for quarrying is mounted on a stone bed,
When the stone bed is inclined, the excavator holding case is tilted by rotating the support rail around the axis, and the suspension frame is tilted in the direction of the support rail with respect to the excavator holding case, thereby suspending the excavator. Hold the frame as vertically as possible. Furthermore, the excavator is rotated around the axis of the suspension frame by the rotating part at the lower end of the suspension frame, and the positions of the plurality of excavators are adjusted along the inclined surface of the stone bed, and the stone bed is excavated in that state. Is what you do.

Therefore, a plurality of excavators mounted on the suspension frame are also located vertically regardless of the inclination of the upper surface of the stone bed, and a vertical excavation can be provided on the stone bed.
