The disassembling machine 2 is provided with presser tool hydraulic cylinders 16 on both sides of the frame 3, and the presser tool 5 is attached to the tip end of the presser tool hydraulic cylinder 16 respectively. Can be reciprocated individually. Therefore, a stable pressing operation is possible even when the pressing portions on both sides of the object to be disassembled 15 are not flat, which is effective for pressing and fixing the object to be disassembled 15 at the time of tearing work or cutting.

In FIG. 5, as in FIG. 4, (a) shows a state in which the presser foot hydraulic cylinder 16 is contracted, and (b) shows an extended state. In the figure, the presser foot 5 is V-shaped, and its center is pivotally attached to the frame 3 and its rear end is pivotally attached to the tip of the presser foot hydraulic cylinder 16. Therefore, when the hydraulic cylinder 16 for the presser tool is expanded and contracted, the tip portion 5a of the presser tool 5 is rotated to press the object to be disassembled.

As described above, in the disassembling apparatus according to the above-described embodiment, the disassembling machine 2 pivotally attached to the tip end portion 1a of the rotating arm 1 is provided with the reciprocating or rotatable holding member 5. Therefore, even if the cutting or tearing point is changed, it is not necessary to frequently move the work vehicle itself unlike the conventional device in which the lower traveling body is provided with a rotation-preventing presser, and the rotation arm is not required. Since it is only necessary to move the dismantling machine 2 by operating 1, it is possible to improve the workability of the dismantling work and reduce the burden on the operator.

Further, since the above-mentioned pressing tool 5 is integrally attached to the dismantling machine 2 attached to the tip portion 1a of the rotating arm 1, the pressing tool is attached to the lower traveling body of the work vehicle as in the conventional case. There is no need to use a specially equipped vehicle with equipment. Therefore, a general-purpose work vehicle can be used and the utilization efficiency of the work vehicle can be improved by merely replacing the dismantling machine 2 having the retainer 5.
