Description

  The present invention relates to a chain-type landmine blasting device as a landmine disposal device that forcibly blows up and processes landmines buried in the ground.

  Currently, large-scale conflicts often occur in various places on the earth, and landmines are used as one of the fighting means. And in order to ensure safe traffic after the ceasefire, it is necessary to process landmines buried in the ground. Conventionally, when handling landmines buried in the ground, an operator generally supports a mine detector, manually operates the mine detector while walking, confirms the location of the mine, and then blows up the mine. We dig up and collect.

  On the other hand, the inventor can process or detect a wide area in a safe manner, and can extend a long reach to a steep slope or a narrow place where machines cannot enter. It is possible to excavate and cut and destroy even land mines for people with earth and sand buried, and in addition to this, a wide range of work by cutting and crushing grass, bushes, land mines, shrubs, stubs, high cocoons, etc. The company applied for and obtained a patent for a large amount that could be used for efficient sorting of debris such as landmines and shrubs after pulverization, or for operations such as leveling and digging.

  This can be cut to a depth of about 30 cm or more by embedding a cutter bit on the peripheral surface of the rotating drum instead of the bucket at the tip of the undulating and refracting arm of heavy equipment vehicles used in excavators such as backhoes. A rotary cutter capable of earth removal is attached to the opposite side to the traveling direction (collectively referred to as a rotary cutter type landmine treatment device).

  Rotating and rotating the rotary cutter at the tip of the undulating and bending arm, operating the boom arm, cutting and crushing bushes, grass etc. growing in the wasteland, and at the same time, anti-personnel mines buried under the ground surface Can be blown up at once. In particular, rotary cutters that rotate at high speeds excavate anti-personnel mines even if they are buried in the soil, and if the cutter bits come into contact with mines, the hit anti-personnel mines are surely blown up.

The rotary cutter type landmine treatment device is effective for small landmines such as anti-personnel landmines, but on the other hand, as a treatment for relatively large landmines such as anti-tank landmines, a chain is provided on a rotating drum and the chain is rotated. A method for exploding landmines that are struck against the ground and buried in the ground is proposed in Patent Document 1 below.
JP-A-9-311000

  In this patent document 1, as shown in FIG. 28, these are a chain provided with a number of chains 16 as a working machine for processing landmines on a traveling body 15 by a crawler traveling body configured similarly to a bulldozer, for example. The thing provided with the rake collection | recovery apparatus 18 which is a mine collection | recovery means for collect | recovering the landmine which could not be blasted by the type landmine blasting device 17 and the chain type landmine blasting device 17 is shown.

  The rake recovery device 18 has a rake body 19 having a receiving plate 20 with a plurality of rake blades 21 attached at equal intervals in the width direction at the lower end, so that landmines can be reliably recovered. A grid-like (or net-like) window portion 22 is provided on the upper portion of the receiving plate 20 so that the tip of the rake recovery device 18 can be viewed from the cab.

  The lower portion of the rake body 19 is pivotally attached to the distal end portions of a pair of swing arms 24 whose base end side is pivotally attached to the track frame 23 of the traveling body 15. A raising / lowering cylinder 25 is pivotally attached to the intermediate portion of the moving arm 24, and the raising / lowering cylinder 25 is operated, whereby the rake body 19 can be raised / lowered around the tip of the swinging arm 24.

  A rod of a rake cylinder 27 that swings the rake body 19 in the vertical direction is pivotally attached to the rear surface of the rake body 19, and an upper end portion of a mounting bracket 28 having a triangular shape provided on the traveling body 15 on the cylinder head side. The rake body 19 can be moved up and down by extending and contracting the rod. The rake body 19 can be tilted in the left-right direction of the traveling body 15 like a normal bulldozer so that a so-called tilt operation can be performed.

  The mine blasting device 17 is attached to the rake body 19. That is, the base end portions of the support arms 29 are swingably attached to both side portions of the rake main body 19, and the rotary shaft 30 to which the chain 16 is attached is rotatably provided at the tip ends of these support arms 29. Further, an oscillating cylinder 31 is pivotally mounted between the upper part of each support arm 29 and the upper part of the support arm 29 of the rake body 19, and the rotary shaft 30 can be moved up and down via the support arm 29. .

  A plurality of chains 16 fixed at appropriate intervals in the axial direction and the circumferential direction of the rotating shaft 30 are fixed to the peripheral surface of the rotating shaft 30. Then, a hydraulic motor connected to one end of the rotary shaft 30 is attached to one end of the support arm 29 and the chain 16 is swung around the rotary shaft 30 by rotationally driving the hydraulic motor. You can hit the ground and give an impact.

  In this way, multiple chains are rotated to hit the ground and blow it up, so there is no need for the operator to process directly on the ground, avoiding the operator's danger, and quick processing. Is possible. And since the mine buried position is deep, those that cannot be blown up and unexploded landmines can be dug up and collected by the rake collection device, so that landmine disposal can be performed safely and reliably.

  However, in the landmine disposal device as in Patent Document 1, there is a possibility that a plurality of chains are tangled with each other. In particular, in an area where shrubs and the like are thick, this tendency is remarkable when the chain is cut and shredded by rotating the chain.

  The object of the present invention is to eliminate the inconvenience of the above-mentioned conventional example, in a chain-type mine blasting device provided on a peripheral surface of a drum as a rotating shaft, a frail hammer provided with a hammer at the tip of a chain, It is an object of the present invention to provide a chain-type mine blasting device that increases the striking force by shortening the chain and makes it easy to escape the blast when encountering a large mine.
