Abstract: An apparatus which gathers earthen cores dug out by a boring machine operates with a main conveyor belt and auxiliary conveyor belt which are partially forced in contact with each other so as to sandwich earthen cores inbetween and transfer the cords to a collecting box. The main conveyor belt is driven by a single drive roller that has axially inclined projecting strips on the end portions so as to prevent the main conveyor belt from shifting in position.
