に設けられたことを特徴とするアースドリル装置。A Kelly bar suspended by a wire through a sheave at the tip of the crane boom, a Kelly bar rotating mechanism that allows the Kelly bar to be vertically inserted so as to be vertically movable and to rotate it, and a lower end of the Kelly bar. It has a cylindrical packet that can be slid up and down, and a pair of double-opening sand discharge doors with drill blades are pivotally attached to the lower opening edge of the packet, and the tips are attached to the inside of these doors. Each base end of the hinged door opening/closing link is pivotally connected to the lower end of the Kelly bar, and when the Kelly bar is lowered relative to the packet, the door is opened and the earth and sand in the packet is released. An earth drill device characterized in that a crown member capable of removably holding the packet when performing the operation is provided at the lower part of the main body of the Kelly bar rotation mechanism.
