Claims (1)

[Scope of Claim for Utility Model Registration] A drilling tower is set up on a skid, a rotating device is attached to the drilling tower so that it can move up and down, and the rotating device rotates and pushes down the drilling rod,
In an excavator that excavates while connecting drilling rods one after another, there is a swing shaft rotatably mounted on the skid, a holding arm attached to the swing shaft, and a swing shaft rotatably attached to the holding arm. an attached rotating shaft; a rod holding mechanism that is attached to the rotating shaft and removably holds a plurality of drilling rods spaced angularly about the rotating shaft; and the rod holding mechanism and the holding arm; a rotation mechanism that is connected to the rod holding mechanism and rotates the rod holding mechanism around the rotation axis; and a rotating mechanism that is connected to the holding arm and the skid and that drives one excavating rod held by the rod holding mechanism for excavation by the drive mechanism. An excavator comprising a rod driving position and a swinging mechanism for moving the rod to another position.
