Claims

[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 and retrieves the drilling rods one after another after the excavation is completed, the connection between the rotating device and the drilling rod and the connection between the drilling rods are each made by screw connection, and the above-mentioned excavation position A rod clamp capable of gripping and fixing a drilling rod is attached to the skit, and a chuck is provided between the rod clamp and the rotating device, and this chuck is capable of gripping a drilling rod connected to the rotating device. An excavator comprising a gripping mechanism that can rotate around the clamp rod, and a rotation mechanism that can rotate the gripping mechanism.
