A control device 6 is housed. An optical system is provided between the operation room 2 and the operator's cab 7 as a guide means having a laser beam irradiating section 8 at the tip and guiding laser light from the laser oscillator 3 to a mine detection position. An extendable guide body 9 is provided.

The laser oscillator 3 is, for example, a YAG laser device, and has a laser wavelength of about 1.6 μm and a maximum output of about 4500 W (pulse).

The guide body 9 connects the base end of the first arm 12 to the upper end of a support pillar 10 erected on the bed portion of the vehicle A via a first universal joint 11, and connects the first arm 1
2 at the tip of the second arm 1 via the second universal joint 13
4 are connected to each other, and a laser beam irradiation unit 8 is provided at the distal end of the second arm 14. The first and second arms 14 have a so-called telescopic structure in which a plurality of cylinders are slidably combined, for example.

The position of the irradiation unit 8 can be adjusted in the range of 0 degrees, and such an operation can be performed by the control device 6 in the operation room 2. Further, the guide body 9 can be operated by an operation lever 15 provided outside the vehicle A.

Further, the land mine disposal device has a protective tube 16 provided between the irradiation part 8 and the land mine detection position and through which the laser light L passes. The material of the protective cylinder 16 is not particularly limited, and may be longer than that shown in FIG. However, the protective cylinder 16
The length is such that if a strong structure is used and the upper end is too close to the irradiating section 8, there is a risk that the detonation of land mines may adversely affect the irradiating section 8. It is desirable to use a simple device that can be destroyed by detonation.

The mine disposal apparatus having the above-described configuration is provided with a vehicle A as a moving means, a laser oscillator 3, a coolant circulating device 4, a guide body 9 provided with an irradiation section 8, a generator 5,
Since the control device 6 is mounted, the entire device can be operated in the vehicle A, and the mine disposal vehicle A
Can act alone, and is highly mobile. In addition, since it can be repeatedly used, the processing cost can be reduced as compared with a case where consumables such as a mine field explosion device are used for a large number of mines.

The processing operation is safely performed at the position where the land mine M is located, and it is possible to process the land mine M irrespective of the type. Further, since the guide member 9 which can be operated by the control device 6 in the operation room 2 is used as the guide means, the safety at the time of processing is further improved with the automation of the guide means, and the protective cylinder 16 is used. This prevents a situation in which an operator looks directly at the intense reflected light of the laser light L emitted from the irradiation unit 8 toward the ground, and secures the safety of the reflected light L in the surroundings.
