Recovery for heavy machinery of recovery methods and surface sediments of the surface sediments

摘要

An object of the present invention is to as accurately capable of recovering the surface sediments with good efficiency. In the recovery process of the A surface sediments 15, in heavy machinery 1 with a convex elastic body 5 to the tip of the arm 2 drive mechanism 3 is provided, working the tip of the arm 2 by running the drive mechanism 3 target portion so close to the work and a pressing step of pressing the predetermined surface of the convex elastic member 5 to the surface of the deposit 15 in a subject position, is moved parallel to the ground surface 20 the end of the arm 2 remains in the pressing state, the convex the surface sediments 15 in pressed by Jo elastic body 5, to perform the transfer process to be moved to a predetermined location 8, which is a destination of the arm 2.FIELD 1
