<p>PURPOSE:To facilitate analysis a lithology data by way of saving labour of formation of the lithology data by providing a detection means to detect each actuation of a machine drill and a rod changer of a drilling device and a drilling data recording device to automatically record a detected data as a data for lithology discrimination at the time when the machine drill is in a drilling state in accordance with the detected data of the detection means. CONSTITUTION:A boom 4 free to lift by a boom lift cylinder 5 is pivotally supported on a front part of a carriage 1 of a crazier drill C. A guide shell 3 with the machine drill 2 mounted on it is pivotally supported on a head end part of the boom 4 free to tilt and swing. A feed motor and a rod changer 7 are provided on the guide shell 3, and extension and collection of a rod 6 of the machine drill 2 is carried out. A stroking pressure detector 21 and a rotational pressure detector 22 are provided on a hydraulic pressure control part 10 on a carriage 1, stroking pressure and rotational pressure are detected, and feed pressure of the feed motor is detected by a feed pressure detector 23. A feed length detector 24 provided on the guide shell 3, feed length of the machine drill 2 is detected, and the rod extension number is detected by providing a rod number detector 25 on the rod changer 7. Additionally, a drilling data recording device 40 is set on an electric control part 11 on the carriage 1.</p> |
