Description

  The present invention relates to a landmine disposer that forcibly blows up and processes a landmine 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 amount of the mine and the shredded wreckage, etc., which are large in volume, can be used to efficiently sort out debris such as landmines and shrubs, or can be used for operations such as leveling and digging.

  As shown in FIG. 22, a cutter bit 11 is implanted on the peripheral surface of a rotating drum 13 instead of a bucket at the tip of a undulating and bendable arm 2 of a heavy machinery vehicle 1 used in an excavator such as a backhoe. In addition, a rotary cutter 12 that can be cut to a depth of about 30 cm or more and can be discharged on the opposite side with respect to the traveling direction is attached (collectively referred to as a rotary cutter type landmine treatment device).

  Turning and rotating the rotary cutter 12 at the end of the undulating and bending arm 2, turning the boom arm, cutting and crushing bushes, grass, etc. growing in the wasteland, and at the same time, interpersonal buried under the ground surface Landmines can be blown up at once. In particular, the rotary cutter 12 that rotates at high speed excavates anti-personnel mines even if they are buried in the soil, and the hit anti-personnel mines are surely blown up when the cutter bit contacts the mines.

  There are many cutter bits, and anti-personnel mines are engulfed and blown up in the rotary cutter. The blown mines are discharged to the ground as remnants of cases, lids, and electric circuit boards.

  The rotary cutter-type landmine disposal device exclusively performs anti-personnel landmine disposal.For relatively large landmines such as anti-tank landmines, a rotary drum is provided with a chain, and the chain is struck against the ground by rotation. Methods for exploding buried landmines have been proposed in the following patent documents and the like (collectively referred to as chain-type landmine blasting devices).

JP 9-311000 A Japanese Patent Laid-Open No. 10-253298 Japanese Patent Laid-Open No. 11-316100

  For example, in Japanese Patent Application Laid-Open No. 9-311000, as shown in FIG. 23, these are a large number of chains as work machines for processing landmines on a traveling body 15 by a crawler traveling body configured similarly to a bulldozer, for example. A chain-type mine blasting device 17 having 16 and a rake recovery device 18 which is a mine collecting means for collecting mine that could not be blasted by the chain-type mine blasting device 17 are shown.

  The rake collection device 18 is provided with a receiving plate 20 having a plurality of rake blades 21 mounted at equal intervals in the width direction at the lower end of the rake body 19, and a grid-like (or net-like) window portion 22 is provided above the receiving plate 20. Was provided.

  The rake body 19 is pivotally attached to the distal ends of a pair of swing arms 24 that are pivotally attached to the track frame 23 of the traveling body 15, and between the upper rear portion of the rake body 19 and the intermediate portion of each swing arm 24. For this, a lifting cylinder 25 was pivotally attached.

  Further, on the back surface of the rake body 19, a rod of a rake cylinder 27 for swinging up and down is pivotally attached.

  The chain-type mine blasting device 17 is attached to the both sides of the rake body 19 so that the base end portions of the support arms 29 can swing freely, and the rotary shaft 30 with the chain 16 attached to the tip portions of these support arms 29 is rotatable. Is provided. Further, a swing 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.

  A plurality of chains 16 fixed at appropriate intervals in the axial direction and the circumferential direction of the rotary shaft 30 are fixed to the peripheral surface of the rotary shaft 30, and one of the support arms 29 has the rotary shaft 30. A hydraulic motor connected to one end was attached.

  In this way, a plurality of chains are rotated to hit the ground and blow up. In addition, those that cannot be blown up due to the deep location of landmines and unexploded landmines are dug up and collected by a rake collection device.

  Although the rotary cutter type landmine treatment device is suitable for the treatment of antipersonnel landmines, it is not suitable for the treatment of relatively large landmines such as antitank landmines. On the other hand, the chain-type landmine disposal device is suitable for the treatment of relatively large landmines such as anti-tank landmines, but is not suitable for the treatment of antipersonnel landmines. However, anti-personnel landmines are small, easy to move, and can not be completely destroyed by bruising the chain of a chain-type landmine disposal device, which may lead to oversight.

  In addition, using two kinds of heavy machinery vehicles, a rotary cutter type landmine disposal device and a chain type landmine disposal device, takes up space and is inferior in workability.

  The object of the present invention is to eliminate the above-described conventional example, and to provide both a rotary cutter type landmine treatment device and a chain type landmine treatment device in one heavy-duty vehicle, so that two types of treatment devices are adapted to the situation of the minefield. It is an object of the present invention to provide a landmine treatment device that can be used separately and can remove both small landmines and large landmines.

In order to achieve the above-mentioned object, the present invention as set forth in claim 1 is provided with a rotating drum instead of a shovel bucket at the tip of a undulating and bendable front arm provided on a turning body of a heavy machinery vehicle used in a shovel machine such as a backhoe. mounting a rotary cutter planted the cutter bit on the peripheral surface, the chain type mine blast device equipped tiltably behind the blast prevention plate provided in the rear portion of the swivel body of the heavy equipment vehicle, on one side of the rotary cutter Has a rake grapple, a magnet on the other side, and a chain-type mine blasting device is installed at the rear of a heavy vehicle with a blast prevention plate with a shock absorber interposed in the support arm, and the upper part of the blast prevention plate is and undulations freely canopy with a window hole for blast vent that provided with a closure plate for opening and closing by a spring, cockpit be summarized in that provided both for the front and for the rear It is intended.

  According to the first aspect of the present invention, by providing both a rotary cutter and a chain-type mine blasting device in one heavy machinery vehicle, the anti-personnel mine is removed by the rotary cutter, and the anti-tank is made by the chain-type mine blasting device. Can remove relatively large landmines such as landmines.

  That is, the antipersonnel landmine disposal operation is performed while the guide bottom surface of the rotary cutter is in contact with the ground surface so that the cutting edge of the cutter bit of the rotary cutter reaches 30 cm underground. Depending on the hardness of the land and unevenness of the ground, the turning speed is changed and sufficient depth is secured by two-step work.

  Antipersonnel mines are blown up by the high speed rotation of the rotary cutter, and fragments are released to the ground.

  Anti-tank landmines are handled with a chain-type mine blasting device, with the flare hammer level, rotating the crushing depth to about 10 cm to 20 cm, and moving the machine body at a constant speed while moving the chain hammer to the ground. Blast mine buried in the ground by slamming into the ground.

  In this way, the present invention has been devised to provide both a rotary cutter and a chain-type mine blasting device in one heavy machinery vehicle, and both the rotary cutter and the chain-type mine blasting device are respectively heavy machinery vehicles. By providing double fronts at the front and rear of the swivel body, it is possible to install a chain-type mine blasting device using the place where this counterweight is provided, eliminating the need for a counterweight that has been required in the past. It was.

You can continue working.

In addition, when it is possible to visually confirm unexploded bombs (UXO) on the ground surface, these unexploded bombs can be grabbed with rake grapples or sucked with a magnet and moved to a safe area from the work area. It can be processed by an appropriate method.

  In addition, metal pieces scattered on the ground surface after the completion of landmine removal with a rotary cutter and chain-type landmine blasting device can be collected by suction with a magnet.

  In addition, rotary cutters can cut shrubs in minefields, but bush cuttings can be removed by grabbing with rake grapples.

  The blast prevention plate prevents blasts and scattered objects from reaching the heavy machinery vehicle, but the top canopy has a window hole for blast blasting. A blast can be missed from here. In addition, a closing plate that is opened and closed by a spring provided in the window hole for removing the blast prevents the fragment from passing through the window hole and hitting the heavy equipment vehicle.

  The shock absorber absorbs the impact of the blast due to the explosion of the mine at the time of the blasting, so that the blast prevention plate and the chain type mine blasting device can avoid the impact.

  By providing both the front and rear cockpits, both the rotary cutter and the chain-type mine blasting device can be operated with their own cockpits.

  As described above, the landmine disposal device of the present invention is provided with both a rotary cutter type landmine disposal device and a chain type landmine disposal device in one heavy-duty vehicle, so that two types of treatment can be performed according to the situation of the landmine field. Equipment can be used properly, and both small and large landmines can be removed.

  Furthermore, when handling landmines that are buried in the ground by hitting a chain hammer against the ground as a treatment for large landmines, each part, including a telescopic mechanism such as a cylinder, is damaged by the explosion of the landmines. There is no fear of receiving.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a side view showing an embodiment of a landmine disposal apparatus according to the present invention, and FIG. 2 is a plan view of the same. As in FIG. 22 showing the conventional example, the landmine disposal apparatus of the present invention is most frequently used in the current market. A heavy machinery vehicle (base machine) 1 used for a shovel such as a backhoe is used.

  A cutter bit 11 is planted on the peripheral surface of the rotating drum 13 in place of the shovel bucket at the tip of the undulating and bendable arm 2 provided in front of the swivel body 7 of the heavy machinery vehicle 1 and cut to a depth of about 30 cm or more. A rotary cutter 12 that is possible and can be discharged on the opposite side of the traveling direction is attached.

  As shown in FIG. 3, the undulating and bendable arm 2 is composed of a boom 2a, an arm 2b, a boom cylinder 2c, an arm cylinder 2d, and a bucket cylinder 2e, and has a holding interval of the pin 6 on the attachment side at its tip. An attachment attachment / detachment device 5 incorporating a variable screw handle type slide mechanism 5b is provided. The attachment attaching / detaching device 5 can be reassembled without removing the attachment pins 6 and is called a quick hitch. The details of the attaching / detaching device 5 will be described with reference to FIG.

  The slide mechanism 5b includes a movable claw 5c, a lock bar 5d, and a set screw 5e. For attachment / detachment, with the attachment-side hydraulic hose removed, retract the movable claw 5c on the other side of the attachment to the attachment / detachment device 5 side, align it with the other pin, and turn the set screw 5e with a tool. To be moved and locked by the lock bar 5d.

  The rotary cutter 12 is directly connected to a hydraulic motor, and a drive motor is coupled to the rotation shaft of the rotary drum 13 on the left and right sides thereof.

  If the cutter bit 11 is arranged in a spiral shape, the screw effect is exerted during cutting, the bush or the like is not entangled, and when the rotary cutter 12 is used in reverse (reverse), the lateral direction is obtained. The soil can be removed.

  Further, a rake grapple 8 is provided on one side of the rotary cutter 12 so that a movable comb blade 8b that is moved by a cylinder with respect to the fixed comb blade 8a is provided so as to be sandwiched, and on the other side. Is provided with an electromagnetic magnet 14. The rake grapple 8 and the magnet 14 can be operated from the driver's seat described later.

  In the figure, 3 is a driver's seat of a heavy machine vehicle (base machine) 1 that is normally used for a shovel such as a backhoe. A special bulletproof glass made of a polycarbonate plate is used for the windshield and floor glass of the window glass. Adopted to give it about 200 times stronger than normal glass. Further, a guard made of a mesh steel net is provided on the front surface.

  The swivel body 7 of the heavy machinery vehicle 1 is provided with a blast prevention plate 32, which is a steel wall plate, facing the rear via a rotatable support arm 37, and further integrated with the blast prevention plate 32 in front of the blast prevention plate 32. Two arms 33 are projected in parallel.

  The support arm 37 for supporting the blast prevention plate 32 raises the support bracket 9 without attaching a counterweight to the rear portion of the revolving body 7 of the heavy machinery vehicle 1 and pivotally attaches one end to the lower portion of the support bracket 9. A link mechanism is formed by being supported by a cylinder 10 from above the support bracket 9.

  Then, as shown in FIGS. 10 and 11, a shock absorber 41 is interposed at the coupling portion between the cylinder 10 and the support arm 37. This shock absorber 41 uses a cylindrical body of urethane foam 41a for high deflection as a buffer, and this urethane foam 41a for high deflection is placed in a clamping device 41b with one end pivoted to close the clamping device 41b. Have a role as a stopper against trying.

  Further, the upper part of the blast prevention plate 32 is pivotally attached as an undulating arc-shaped canopy 40. As shown in FIGS. 4 and 5, the canopy 40 is provided with a number of rectangular window holes 42 for removing the blast. They are densely arranged as window holes. The window hole 42 is closed by a closing plate 43 that is opened and closed by a spring at the hinge portion. The closing plate 43 opens only behind the canopy 40 when receiving a strong blast due to the mine explosion (see FIG. 4), and normally closes the window hole 42. The canopy 40 is locked with a support bar 38 that can be extended and contracted on the arm 33.

  The arm 33 is arranged in a straight line on the support arm 37, and a chain mine blasting device 36 is configured by supporting a drum 35 provided with a chain hammer (frail hammer) 34 at its tip. In the figure, reference numeral 39 denotes a motor that rotates the drum 35 and is provided on the arm 33.

  As shown in FIGS. 6 to 8, the chain hammer 34 is provided with a weight 34b at the tip of the chain 34a. The chain hammer 34 is arranged in a radial manner in the axial cross-sectional direction of the drum 35 and in parallel with a gap in the length direction. In this manner, the drum 35 was attached in a radial shape. The connecting pieces 35a of the chain 34a on the peripheral surface of the drum 35 are also arranged in a staggered manner as shown in FIG. 9, and a spiral is drawn in the axial direction of the drum 35. This is to prevent entanglement.

  In addition to the driver's seat 3, a rear driver's seat 44 is formed in the revolving body 7 so as to be a double cab type. The driver seat 44 is provided with the same protective mechanism as the driver seat 3.

  Further, as shown in FIGS. 12 to 14, as a countermeasure against dust, the revolving body 7 has an engine 49 interposed between a suction duct 45 that opens to the front side on one side and a discharge duct 46 that opens to the front side on the other side. Position and communicate with each other.

  An electric fan 48 is installed in the suction duct 45 and the discharge duct 46, and the air sucked from the suction duct 45 is forcibly exhausted from the discharge duct 46, and the air for cooling the engine is taken in from the front side and discharged to the front side. Thereby, it is possible to prevent the engine 49 from covering the dust generated by the chain mine blasting device 36 at the rear as much as possible. In the figure, 47 is a pre-cleaner.

  Next, the usage will be described. First, in the minefield, the presence or absence of unexploded shells 50 on the ground surface is confirmed visually. (See Figure 15)

  If the unexploded shell 50 is present, it is removed. As shown in FIG. 16, the small unexploded shell 50 can be moved by being sandwiched between rake grapples 8 or attracted with a magnet 14. Large unexploded munitions are removed by human power and processed manually after moving from the work area to the safety zone.

  As shown in FIG. 17, the anti-tank mine has a chain-type mine blasting device 36 (Frail hammer) in a horizontal state, and the crushing depth is adjusted to about 10 cm to 20 cm while rotating the machine body at a constant speed. By knocking the chain hammer 34 against the ground by the rotation of the drum 35, the landmine buried in the ground is blown up.

  In this case, the driver moves from the driver's seat 3 to the driver's seat 44 that is one step higher, and operates while looking at the back. Further, as shown in the figure, the arm 2 provided with the rotary cutter 12 is folded so that the stability on the entire lance is maintained. (Instead of counterweight.)

  During the mine blasting, the shock absorber 41 absorbs the impact of the blast due to the mine explosion, so that the blast prevention plate 32 and the chain-type mine blasting device 36 can avoid the impact.

  If the determined distance has been processed, the next step is to remove the anti-personnel mine with the rotary cutter 12 as shown in FIGS. Again, the operator moves to the driver's seat 3 and operates the rotary cutter 12 with the arms 2 that can be raised and lowered while the heavy machinery vehicle 1 travels in the reverse direction. The rotary cutter 12 is turned while being in contact with the ground surface so that the cutting edge of the cutter bit 11 of the rotary cutter 12 reaches 30 cm underground. Depending on the hardness of the land and unevenness of the ground, the turning speed is changed and sufficient depth is secured by two-step work.

  Antipersonnel mines are exploded by high-speed rotation of the rotary cutter 12, and fragments are released to the ground.

  Further, as shown in FIG. 20, the processing of the rotary cutter 12 is effective for removing antipersonnel landmines such as slopes and waterways.

  When the rotary cutter 12 is operated, the chain-type mine blasting device 36 is not in use, but is suspended by the cylinder 10 to balance the whole, and the canopy 40 is also formed of a wire or the like. It is suspended and fixed to the support bracket 9.

  When the mine removal operation is completed by the chain-type mine blasting device 36 (Frail hammer) and the rotary cutter 12, the metal pieces scattered on the ground surface are collected by the magnet 14 attached to the rotary cutter 12.

  The rotary cutter 12 has the ability to remove shrubs in a minefield. It can handle up to 25-30cm diameter trees from the bush. Further, the rake grapple 8 provided can be cleaned up safely.

  In the operation in the shrub zone, with the main body stopped, first, bush cutting is performed as shown in FIG. 21, and then, the removal work with the rake grapple 8 is started. At this time, the use removal apparatus can be changed by rotating the upper part of the excavator by 180 degrees, and continuous work can be performed.
