SOLUTION: This mine removing device is provided with a plurality of front wheels, each of which is equipped with a main shaft on a supporting arm attached to a vehicle, such as the power shovel, etc., and a spur gear type vertically movable pressing section in front of the main shaft; a plurality of rear wheels which can be moved upward and downward similarly to the front wheels so that the wheels may be positioned between the front wheels in the rear of the main shafts; and vertically movable rollers which are provided on auxiliary shafts provided on the supporting arms for making final checking.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mine eliminator for bombing (removing) a lot of land mines buried underground (ground surface) at a time.

[0002]

2. Description of the Related Art As a conventional technique, an operator has a metal detector and searches for a mine while tracing the ground. In addition, the mines that have been found are either blown up on the spot or brought to the disposal site for collective disposal (blasting).

[0003] In the above method, manual work is mainly performed.
It is dangerous, it takes a lot of time and huge removal cost,
It has various problems in practical use.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above problems, and has as its object to solve the problems of the conventional technology and equipment, and to quickly massapse a large number of land mines on a humanitarian road. It is intended to provide a demining device that can be removed (blasted) reliably and safely.

[0005]

As a means for solving the problems, a front wheel provided with a main shaft on a support arm attached to a vehicle such as a power shovel and a pressing portion of a spur gear type movable up and down in front of the main shaft is provided. A plurality of rear wheels that can move up and down like the front wheel are provided to be located in the gap between the front wheel and the front wheel behind the main shaft, and the auxiliary shaft provided on the support arm can be moved up and down to make a final check Roller. The rear wheel pressing portion presses a position other than the position pressed by the front wheel pressing portion. Further, a hanger for suspending the support arm when changing the course is provided. Further, a metal detector is provided in front of the front wheel.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A mine eliminator 1 includes a vertical excavator 4 which is sandwiched between mounting plates 4a, 4a in front of a main shaft 3 provided at a distal end between support arms 2, 2 mounted on both sides of a vehicle such as a power shovel. A plurality of (five in this embodiment) front wheels 4 having a movable spur gear type and formed with a pressing portion 4b are provided, and the front wheels 4 are located adjacent to the rear of the main shaft 3 and are positioned between the front wheels 4.
A plurality of rear wheels 5 (four in this embodiment) that can move up and down like the front wheels 4 are provided, and an auxiliary shaft 8 provided at a rear portion between the support arms 2 is moved up and down by a support plate 6b. The roller 6 is formed of three cylindrical small rollers 6a, each of which is provided at a position corresponding to a gap between the adjacent rear wheel 5 and the rear shaft 5. In addition, front wheel 4
In order to press the portion (position) other than the position pressed by the pressing portion 4b of the rear wheel 5 with the pressing portion 5b of the rear wheel 5, it is configured (for example, interlocked with a chain or the like). Further, when the course is changed, the support arm 2 is attached to the arm of the power shovel, and a lifting device 7 is provided by a chain for lifting.

Next, an example of use of the demining apparatus 1 will be described. The excavator P (with the excavator removed) is fixed to both sides of the caterpillar K with fixing screws B, B, and the hanging member 7 is attached to the tip of the arm A. In this state, the power shovel P is operated to travel (forward) in the mine buried area, so that the mine G1 is first blown up by the pressing portion 4b of the front wheel 4--. At this time, the blast can be prevented between the pressing portions 4b, and does not affect the operator (driver). In addition, mine G2 that could not be blasted with the front wheels 4 ----
Is blown up by the pressing portion 5b of the rear wheel 5. Up to this point, most land mines have been exploded, but the land roller G3 can be exploded by the rearmost roller 6 just in case. Next, when the place (direction) is changed, the support arm 2.2 is lifted by the lifting tool 7 by raising the arm A of the excavator P, and the front wheel 4 ---- the rear wheel 5
−−− and the roller 6 are separated from the ground M, the direction of the power shovel P is changed, the arm A is lowered, and the front wheel 4 -−− is used.
-Land the rear wheel 5 and the roller 6 on the ground M, and perform the same operation as above.

In the above embodiment, the vehicle to be used is not limited to a power shovel, but may be a bulltozer or the like. The size and number of the front and rear wheels, the pitch of the pressing portions, and the like may be set as necessary. The same applies to the small roller, and the roller may be one large roller. Further, the material is not particularly limited as long as it can withstand blasting, and the hanging tool is not limited to a chain as long as it has a similar function. Furthermore, a metal detector may be provided in front of the front wheels.

[0009]

According to the present invention, the combination of a front wheel, a rear wheel, and a roller makes it possible to reliably remove (blast) a mine. 2) In particular, by providing a plurality of front wheels and rear wheels,
It can also respond to undulations on the ground. 3) The worker (driver) can work safely. 4) The course can be easily changed. 5) By attaching a metal detector, work can be performed more effectively.
