Description

 BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an apparatus for removing land mines and miscellaneous trees,

The present invention relates to a land mine removing apparatus, and more particularly, to a tree removing and mine removing apparatus which is mounted on a boom of an excavator and is capable of removing buried land mines by floating, .

In order to remove explosives such as mines buried in the ground, a person enters the landmine directly and uses a detector, or digs a buried landmine while inserting the probe into the ground, and performs a demolition of the landmine.

In this method, people enter the landmine buried directly, which can cause personal injury due to landmine explosion, etc., and it takes much time to remove landmines. Also, there is a problem that it is very difficult to detect because the plastic mine is not detected by the detector.

As a removal device considering this, a plurality of fork-type ground excavators are mounted on the front of a bulldozer or a tank (tank) so as to be inclined. When the ground excavator is advanced to the depth where the land mine is buried, And the pressure or the pressure to be applied to the liquid. Also, the land mines exposed to the ground by hanging on the fork of the excavator are removed by blasting or removing them, or by blowing them into the crusher so that they enter into the crusher mounted separately on the excavator.

Although the above equipment and method can economically, safely and quickly remove land mines, in Korea's terrain where the height of the ground is high, land mines buried lower than the surrounding ground can be removed without removing them. It is difficult to increase the reliability of the operation.

Especially, when the trees and bushes including the bushes are thick, they are obstacles to the landmine removal work and it is practically impossible to carry out the landmine work.

Korean Patent Publication No. 2002-0020460 discloses a method of removing land mines and a device therefor. The posted land mine removing device has a land mine removing device capable of removing trees in landfill areas and exploding land mines buried in the ground, and a shaft and a towing device installed in the land mine removing device.

Korean Patent Publication No. 2012-019092 discloses a frame type mine and vegetation removal device using an excavator, and Korean Patent Publication No. 2012-012623 discloses a device for removing a magnetic mine using an excavator.

As described above, the land mine removing device has a structure for removing the land mine by pressing or using magnetic force. Therefore, when the land mine is relatively deeply buried or obstructed by obstacles, the reliability of the land mine removing is not relatively high .

Japanese Patent Application No. 1998-072433 discloses a robot for removing land mines. The published robot has a pressure body that applies pressure to the primer of a land mine. When the primer protrudes to the ground because the contact area of the pressure body with the ground is not specified, the pressure body is controlled by the force applied to the primer, However, there is a disadvantage that if a primer is buried underground, it can not be properly demolished and removed.

Korean Patent Publication No. 10-2012-0019093 discloses a rotary type vegetation removing apparatus using an excavator.

The disclosed planting apparatus has a configuration in which a plant removing means is mounted on a conventional excavator equipped with a multi-joint link and has a link connection portion at a bucket mounting portion of the end of the multi-joint link.

The hydraulic motor may be located inside the cutting drum 95 while being supported by the lawn mower body 91 so as not to protrude to the outside.

Hereinafter, the operation of the land mine removing apparatus according to the present invention will be described.

In order to remove the land mines in the landfill area, the boom 110 of the excavator 100 and the bracket 11 of the land mine removal device are connected. In this state, after the landing area of the land mine is moved, the opening side of the bucket 30 is directed in the forward direction, that is, toward the front, and the cover arm 70 is moved to the hydraulic cylinder .

Then, the bucket 30 is inserted into the landmine buried area as shown in FIG. The insertion of the bucket 30 is completed and the actuator of the vibration generating unit 50, that is, the hydraulic motor, is driven to vibrate the vibration generating unit 50. This allows the bucket 30 to vibrate at a high speed to soften the ground in the area where the bucket 30 is inserted.

At this time, the vibration of the bucket 30, that is, the vibration generated from the vibration generating unit 50, can be prevented from being transmitted to the boom 110 of the rotating unit 20 and the excavator 100.

More specifically, the vibration generated from the vibration generating unit 50 is applied to the vibration damping unit 60, that is, the application and registration of the present invention, and the high load applied between the bucket 30 and the rotary unit 20 Absorbed by the vibration dampener. When the bucket 30 is oscillated, the first and second brackets rotate relative to each other while rotating the rotary shaft. The elastic members installed between the first and second brackets are stretched and contracted, Is absorbed.

This operation and configuration are described in detail in Korean Patent Registration No. 101424110, and will not be described again.

When the excavator advances in the above process, the land mine buried in the ground is floated. When the buried land mine is blasted in the process of separating the land mine, the bucket 30 and the cover arm 70, The fragments can be prevented from scattering.

The movement of land mines contained in the bucket 30 in a state where the land mine is lifted and separated as described above can be safely carried by blocking the opening portion by rotating the cover arm 70 with respect to the bucket 30 .

6 and 7, in order to cut the trees in the landfill area, the bucket 30 is rotated by the rotation unit 20 and the direction in which the cover arm 70 is opened with respect to the bucket 30 .

 In this state, the tree 300 to be cut is positioned between the bucket 30 and the cover arm 70, and then the first drive unit 72 operates the hydraulic motor to cover the bucket 30, The arm 70 is rotated in the closing direction to grasp the tree.

When the tree is gripped as described above, the hydraulic cylinder, which is the second driving unit 85, is operated to rotate the cutting blade 81 to cut it as shown in FIG. As shown in FIG. 8, the cover arm 70 and the cutting blade 81 can also cut the tree 300 having a relatively small diameter.

  In the case of a vertically erected tree or a tree cut with a period, the cutting operation of the tree can be performed as described above while rotating the bucket 30 by the turning means 20. [

9, the cutting drum 92 rotatably installed on the lawn mower body 91 of the lawn mower unit 90 is directed downward, and the third driving unit (not shown) 99). ≪ / RTI > In this manner, while the cutting drum 92 is being rotated, the work is performed by the lawn mower blade 95 provided on the outer circumferential surface of the cutting drum 92.

The grass cut and separated into the grass mower unit (90) can be collected in the bucket (30) and recovered.

The tree removal and mine removal device as described above can remove the anti-personnel mines manufactured by the plastic which is not detected by the mine detector, and can perform the mine work while removing the trees, Therefore, the reliability of the removal of land mines can be improved.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art.

Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.

The deforestation and land mine removing apparatus according to the present invention can be widely applied not only to mine landmine removal, but also to removal of gravel and stones buried in soil, various civil and industrial facilities, and logging operations.
