The invention discloses an obstacle removing barrel of an abrasion drill. The obstacle removing barrel comprises a cylindrical barrel body (1) with one end opened; a wire rope I (2) and a wire rope II (3) extended towards the inner part of the cylindrical barrel body (1) are arranged on the side wall of an opening end of the cylindrical barrel body (1) at intervals along the peripheral direction; the wire rope I (2) is deviated from the center of a circle, and length of the wire rope I (2) is bigger than outside radius of the cylindrical barrel body (1); adjacent wire ropes I (2) are intersected towards the extending end of the inner part of the cylindrical barrel body (1), and the wire rope II (3) points to the center of the circle; a steel pipe (4) is welded on the end face of the other end of the cylindrical barrel body (1), and an obstacle taking hole (6) is arranged on the end face of the cylindrical barrel body (1); a flange disk (5) is arranged on the steel pipe (4), and the flange disk (5) is connected with a drill stem of the abrasion drill. The obstacle removing barrel of the abrasion drill is convenient to operate, and solves the problem that the abrasion drill cannot drill in a miscellaneous fill layer having big rubbles, concrete blocks and brick blocks.
