TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a land mine disposal device that can efficiently treat land mines and also secure agricultural land by improving farm land.
[0002]
[Prior art]
Conventionally, all landmines for human use have been manually processed. In detail, they first detect one by one using a mine detector, similar to a metal detector, usually fixed on a long rod. If you can detect it, water it, soften the soil and check the mine situation. The mines are set in a visible state by removing the soil with a brush or the like, and then explosives are set up to trigger the explosion. In this way, the conventional processing of land mines depends on the experience and perception of a person with specialized skills one by one. It goes without saying that you have to spend a lot of time and effort.

In particular, since the rotary cutter 9 that rotates at high speed can cut to a depth of about 30 cm, even if an antipersonnel mine is buried in the soil, it is dug out, and when the cutter bit 11 comes into contact with the mine, the antipersonnel mine is hit. Deformation destroys the internal explosive series and cuts the electric circuit.
[0010]
At the next tooth (cutter bit 11), the antipersonnel mine is caught in the rotary cutter 9, the case and the lid are separated, and the explosives are scattered.
[0011]
Therefore, the antipersonnel mine of the electric fuze does not explode at all, while the antipersonnel mine of the mechanical fuze only explodes only the fuze and does not explode the main body of the antipersonnel mine. Treated land mines are separated into cases, lids, and electric circuit boards, and are discharged to the ground.They are discharged on the opposite side to the direction of travel, so that mud does not cover and bury the anti-personnel land mines. .
