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.

Japanese Patent Laid-Open No. 11-183095 (Japanese Patent No. 3177737) JP 2000-130996 A (Patent No. 3016018) JP 2001-74398 A (Patent No. 3096847)

  As shown in FIG. 26, the cutter bit 11 is implanted on the peripheral surface of the rotary drum 13 instead of the bucket at the tip of the undulating and bendable arm 2 of the heavy-duty vehicle 1 used in the 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 is exclusively used for anti-personnel landmine disposal.For relatively large landmines such as anti-tank landmines, a rotating drum is provided with a chain, and the chain is struck against the ground by rotation. A method of detonating landmines buried in the ground has been proposed in the following patent documents (collectively referred to as chain-type landmine blasting devices).

JP-A-9-311000 JP-A-10-253298 JP 11-316100 A

  For example, in Japanese Patent Application Laid-Open No. 10-253298, as shown in FIG. 25, these are, for example, the undulating and refracting arms 21 provided on the revolving body 17 of the traveling body 15 by the crawler traveling body configured similarly to the backhoe. As a working machine for treating landmines at the tip, a machine equipped with a chain-type mine blasting device 24 having a flail hammer 28 configured by attaching a swing weight 26 to the tip of a chain 27 is shown.

  The chain-type mine blasting device 24 is a chain of a plurality of flail hammers 28 fixed to the circumferential surface of a rotating shaft 23 mounted laterally with respect to the arm 21 at appropriate intervals in the axial direction and the circumferential direction of the rotating shaft 23. 27 is fixed, and the flare hammer 28 is rotated in the front-rear direction of the arm 21 to hit the ground and blow it up.

  However, when a relatively large land mine such as an anti-tank land mine explodes, a large amount of smoke generated by the explosion floats around. Furthermore, when the ground around the land mine is dry, the surrounding dry soil is rolled up in the air along with the explosion, and a large amount of dust is also scattered around.

  Moreover, since the flare hammer 28 rotates in the front-rear direction of the arm 21, smoke and dust block the view from the cab 18 of the traveling body 15 to the vicinity of the tip of the arm 21 that is the work place until the view is restored. Landmine disposal work must be temporarily suspended.

  On the other hand, the following patent document shows a configuration in which the upper side of a work machine for treating landmines is covered with a cover to prevent debris scattering and smoke diffusion associated with landmine explosions. Also assumes relatively small landmines, such as antipersonnel landmines, and does not assume the handling of large landmines.

JP 2003-042698 A JP 2002-340499 A

  For example, in Japanese Patent Application Laid-Open No. 2003-042698, a cover that covers an upper portion of a work machine for processing landmines is provided with a through hole that allows a blast to escape.

  However, if the through-hole is large, explosive smoke and dust will leak out from the through-hole, and the view will be blocked. On the other hand, if the through-hole is small, the blast cannot be sufficiently released, and the cover will receive the momentum of the blast and the possibility of breakage increases.

  The object of the present invention is to eliminate the above-mentioned conventional example, and in a landmine disposal device provided with a chain-type landmine blasting device that treats relatively large landmines such as anti-tank landmines, the work efficiency is high and the safety of the work is also high. It is to provide a landmine disposal device.

  In order to achieve the above object, the present invention as claimed in claim 1 supports a drum provided with a flare hammer at the tip of a undulating and bendable arm provided on a swinging body of a heavy machinery vehicle used in a shovel machine such as a backhoe. The gist of the present invention is that the chain-type mine blasting device is attached so that the rotation direction of the flare hammer is perpendicular to the longitudinal direction of the arm.

Furthermore, the chain-type mine blasting device is detachably fixed to the tip of the undulating and refracting arm via a quick hitch attachment attaching / detaching device, and a guard plate is provided on the side of the chain-type mine blasting device. This is the gist.

The guard plate is tiltably provided on a support frame formed on the side of the chain-type mine blasting device, and the back surface of the guard plate is supported by a cylinder with a damper pivotally attached to the support frame. It is a summary.

  According to the first aspect of the present invention, a chain-type land mine targeting a relatively large land mine such as an anti-tank land mine with a pivot shaft attached parallel to the longitudinal direction of the arm provided on the revolving structure. Since the flare hammer of the blasting device rotates in the transverse direction perpendicular to the longitudinal direction of the arm, the smoke and dust generated by the explosion of the land mine is swept laterally along the direction of the flare hammer operation. The field of view from the room to the vicinity of the arm tip, which is the work place, is not obstructed by smoke or dust, and the field of view can be secured even during landmine disposal work, thus improving work efficiency.

  In addition, the fact that the rotation direction of the flail hammer is in the lateral direction in this manner is that the scattered objects are also flowed in that direction, so that the flail hammer does not go to the cab side and is highly safe.

In addition, the chain-type mine blasting device can be attached to the tip of a undulating and refracting arm via a quick hitch attachment attaching / detaching device, so that it can be attached to another attachment, for example, a rotary cutter type landmine treatment. Replacement with a device can be performed easily and quickly, and can be widely used. In addition, since the guard plate, which is a steel wall plate, is provided, it is possible to prevent debris and pebbles scattered by the mine explosion at the tip of the arm, and the work safety is high.

In addition , a cylinder with a built-in damper provided between the guard plate and the support frame formed on the side of the chain-type mine blasting device acts as a shock absorber, and a relatively large mine explosion such as an anti-tank mine. Since the shock absorber absorbs the momentum applied to the guard plate at this time, the guard plate can be protected from the blast, and the moment does not reach the arm and the arm is not damaged.

  The gist of the present invention described in claim 2 is that the revolving unit is provided with a blower for blowing air in front of the arm.

  According to the second aspect of the present invention, air is blown forward of the arm by the blower provided in front of the revolving structure, and the explosive smoke and dust generated near the tip of the arm, which is the work place, are removed by the flow of air. Therefore, even if a relatively large mine such as an anti-tank mine is exploded, the view from the cab of the heavy machinery vehicle to the vicinity of the arm tip, which is the work place, is not obstructed by smoke or dust, Visibility can be secured even during landmine disposal work, and work efficiency is good.

  The gist of the present invention described in claim 3 is that the upper part of the chain-type mine blasting device is covered with a cover frame, and the chain shank hanging below the cover frame surrounds the lower half of the chain-type mine blasting device. is there.

  According to the third aspect of the present invention, the chain blind hanging below the cover frame allows the blast to escape from the eyes of the chain and can prevent scattering of debris and pebbles caused by the mine explosion, so that the work safety is ensured. Is expensive.

  In addition, only the upper end of the chain that constitutes the chain blind is fixed, and the lower end is a free end, so when the blast pressure is high, the blast can escape from below the chain blind, It will not be damaged by the impact of the blast.

  In this way, a large blast escapes from the bottom of the chain blind, so the blast crawls near the surface and does not wind up dust.

  The gist of the present invention described in claim 4 is to provide a rake toward a lower side of a support frame formed on a side portion of the chain-type mine blasting device.

  According to the fourth aspect of the present invention, since the rake is provided behind the chain-type mine blasting device, the blasting blasting is caused by the deep mine burial position in addition to the large debris generated by the mine explosion and the tree branches scattered around. What can not be done and unexploded landmines can be dug up and collected by rake, eliminating the need to replace the equipment every time the mine blasting and recovery processes are performed, thus improving work efficiency.

  The gist of the present invention described in claim 5 is that a magnet is provided to be movable up and down behind the chain-type landmine blasting device, and the shock absorber is provided between the blast prevention cover main body and the magnet. .

  According to the fifth aspect of the present invention, since the magnet is provided at the rear of the chain-type mine blasting device, it is possible to collect the mine fragments that have been shattered by the explosion with the magnet. Work efficiency when processing is good.

  Also, if the magnet is raised except when it is in use, it will not interfere with other operations such as mine blasting and rake operations.

  As described above, the landmine disposal device of the present invention is a landmine disposal device equipped with a chain-type landmine blasting device that treats relatively large landmines such as anti-tank landmines. Since the flail hammer of the target chain-type mine blasting device rotates in the transverse direction perpendicular to the longitudinal direction of the arm, the smoke and dust generated by the mine explosion flow laterally along the rotation direction of the flail hammer. From the driver's cab of the heavy machinery vehicle to the vicinity of the arm tip, which is the work place, is not obstructed by smoke and dust, ensuring visibility during landmine disposal work, and improving the efficiency of the work. Since it is swept away, there is little going to the driver's cab side and it is highly safe.

  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. Like FIG. 22 showing the conventional example, the landmine disposal apparatus according to the present invention is also a shovel such as a backhoe that is most frequently used in the market. A heavy machine vehicle (base machine) 1 to be used is used, and this heavy machine vehicle 1 is provided with a undulating and bendable arm 2 and a soil discharge plate 10.

  Reference numeral 3 denotes a driver's seat (cabin), and reference numeral 4 denotes a crawler belt for traveling. However, in addition to such a crawler type, a wheel type having wheels instead of the crawler belt may be used. The crawler belt 4 demonstrates its power on steep slopes, etc., but in the case of the wheel type, the forward (rear) advance on the flat ground increases. The earth discharging plate 10 is an explosion-proof blade and has a blade cylinder 10a.

  As shown in FIG. 2, 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 at its tip, as shown in FIGS.

  In the quick hitch, the slide mechanism 5b includes a movable claw 5c of an S-arm, a lock bar 5d, and a set screw 5e. For attachment / detachment, with the hydraulic hose on the attachment side removed, the movable claw 5c on the other side of the attachment detaching device 5 is contracted to the attachment detaching device 5 side. It is moved by a tool and moved by a lock bar 5d (mechanical type).

  As shown in FIGS. 21 and 22, the quick hitch may incorporate a hydraulic cylinder 5f instead of the set screw 5e so that the S-arm of the movable claw 5c operates hydraulically. In FIG. 22, 5g is a valve of the hydraulic cylinder 5f, and 5h is a pin lock.

  The chain-type mine blasting device 36 is configured as an attachment that detachably fixes a side to the tip of the undulating and refracting arm 2 via the attachment attaching / detaching device 5, and is also shown in FIGS. As described above, the flare hammer 34 that is a flare hammer rotating around the drum 35 is provided on the peripheral surface of the drum 35.

  As shown in FIG. 9, the flail hammer 34 has a weight 34b provided at the end of a chain 34a via a shackle 34c. Although the weight 34b is not shown in the drawing, the striking surface has a warped curvature surface. It can also be. Another example of the flare hammer 34 is shown in FIGS. The weight 34 was bound to the chain 34a by a bolt shaft 34d. The weight 34b has a protrusion 34e formed on the outer periphery of the lower end.

  The drum 35 is provided with a drive motor 39 at its end, and is supported on the left and right by a support plate 46 suspended from an arm 33 that supports a chain-type landmine blasting device 36. The arm 33 and the side guard 45a constitute a cover frame 45 that covers the chain mine blasting device 36.

  The cover frame 45 is formed into a bowl shape by incorporating a small beam 46a and a string material 46b in addition to the arm 33 and the side guard 45a, and the front surface of the rotation area of the flail hammer 34 of the chain-type mine blasting device 36, Cover the rear and upper side.

  Further, around the lower end of the cover frame 45, only the upper end of the chain is fixed and attached in a comb shape to form a chain blind 49 that hangs downward, and the chain half 49 is the lower half of the chain-type landmine blasting device 36. Surrounded the surroundings.

  The length of the chain blind 49 is set such that the lower end of the chain blind 49 reaches the ground when the chain type mine blasting device 36 is used.

  It should be noted that the drum 35 and the arm 33 which are the rotation shafts of the flare hammer 34 are parallel to the front and rear direction of the undulating and bendable arm 2, and the support plate 46 is located in front of and behind the arm 33 and the drum 35. The rear support plate 46 is coupled to a support frame 44 formed on a side portion of the chain-type mine blasting device 36.

  A guard plate 32, which is a steel wall plate, is pivotally attached to the support frame 44 and is provided so as to be tiltable. A cylinder 41 with a built-in damper 41 a is attached to the back surface of the guard plate 32. It was supported like a slanted holding bar.

  The cylinder 41 has an inner tube 41b and an outer tube 41c fitted and slid, and an end portion is pivotally attached by a pin. The damper 41a is made of foamed urethane for high deflection and used as a buffer for foamed urethane for high deflection. The action absorbs the displacement of the inner tube 41b and the outer tube 41c.

  In addition, a coil spring or the like can be used as the damper 41a in addition to the foamed urethane for high deflection.

  In addition, in order to protect the rake 9 and the magnet 47 from debris and pebbles scattered by the explosion, it is preferable to attach a chain blind to the lower side of the guard plate 32 as well.

  In FIG. 1, 9 is a rake provided downwardly on the support frame 44. As is well known, the rake has a hook-like shape, and has a hook blade 9b provided with a rake blade 9a at the tip with a space in the width direction. The gap between the lower portions of the scissors blade 9b was configured as a lattice 9c by a horizontal rail.

  As shown in FIG. 6, a magnet lifting device 48 having a magnet 47 at the lower end is attached and fixed to the front side of the rake 9 body. The magnet elevating device 48 is a hydraulic cylinder, and moves the magnet 47 at the lower end up and down by extending and contracting.

  The magnet 47 is an electromagnet as shown in FIG. 7, and supplies power to a heavy machine vehicle (base machine) 1 used in a shovel such as a backhoe by an operation switch.

  The magnet 47 is connected to a battery 53 serving as a power source for the heavy-duty vehicle (base machine) 1 via a control panel 54, and an operation switch 55 provided in the driver's seat (cabin) 3 is connected to the control panel 54. The ON / OFF control of the magnet 47 is performed by the switch 55.

  A cable from the magnet 47 to the control panel 54 enters the heavy machinery vehicle (base machine) 1 along the arm 2 that is undulating and bendable.

  Further, as shown in FIG. 1, an air blower 51 that rotates and blows air by using an electric motor that drives a rotating shaft of a blower fan by a hydraulic power generator 51 a is attached to the upper front of the traveling body 15. In addition, the attachment angle of the air blower 51 is set so that the air blowing direction of the air blower 51 is in front of the undulating and bendable arm 2.

  Next, the usage will be described. When the landmine disposal apparatus (system) according to the present invention is used in a place where it is expected that there are landmines or the like based on the preliminary survey results of various kinds of information, it is necessary to prepare in advance for the efficiency of the entire work.

  First, the work position is confirmed. Place the reference pile at the starting point of the work and plot the position of the pile from a clear survey point. This is important for work records, reporting, and mine disposal mapping. Next, a work section is set. In order to minimize the movement distance of the machine body and increase the work efficiency, the work section is planned in consideration of appropriate replacement with the rotary cutter as an attachment according to the terrain and vegetation.

  Although illustration of the rotary cutter is omitted, Japanese Patent Application Laid-Open No. 11-183095 (Patent No. 3177737) of Patent Document 1, Japanese Patent Application Laid-Open No. 2000-130996 (Patent No. 3016018) of Patent Document 2, and Patent Document 3 are disclosed. JP-A-2001-74398 (Patent No. 3096847) and the like.

  The heavy machinery vehicle 1 moves forward and backward by the crawler belt 4 and the wheels, and turns. An operator rides on the driver's seat 3 and operates the rotary cutter by the undulating and refracting arm 2, but trees, shrubs, bushes and grass covering the ground surface interfere with detection and processing operations such as landmines. In this case, it can be easily processed by moving the rotary cutter while turning from the side.

  However, if it is expected that there will be unexploded shells hidden inside the vegetation and it is difficult to see before work, safety will be ensured at the work stage. In the first stage, the vegetation is cut at a height of 30 to 40 cm above the ground so as not to touch unexploded shells. In the second stage, the vegetation is cut to 10 cm or less so that the subsequent detection work can be easily performed.

  Anti-personnel mines are processed by clearing all areas with a rotary cutter, focusing on the positions of anti-personnel mines revealed by detection work. In the processing operation, the rotary cutter is rotated 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.

  Anti-personnel mines are destroyed without exploding by high-speed rotation of the rotary cutter, and fragments are released to the ground. Depending on the type, only the fuze may burst, but there is no effect on the device.

  The anti-tank mine and unexploded bombs exchange the rotary cutter, and the chain-type mine blasting device 36 blows the flare hammer 34 against the ground by rotating the drum 35, thereby blasting the mine buried in the ground.

  At this time, the drum 35 is parallel to the undulating and refracting arm 2 in the front-rear direction, and the rotation direction of the flail hammer 34 is lateral to the undulating and refracting arm 2. The generated smoke and dust are caused to flow laterally along the rotation direction of the flare hammer 34, and the view from the driver's seat 3 of the heavy machinery vehicle 1 to the vicinity of the tip of the arm 2b, which is the work place, is not obstructed by the smoke or dust. .

  Under the cover frame 45, there is a chain blind 49 whose lower end is a free end, so that the chain blind 49 can prevent mine fragments and pebbles from scattering due to the momentum of the mine explosion, and chain the blast. It escapes mainly from the bottom of the blind 49 and prevents smoke and dust from flying up.

  Also, when a plurality of landmines are concentrated in a narrow place, or when the ground or air is extremely dry and the amount of smoke or dust rising due to an explosion is significant, the blower 51 is driven and the arm 2b By blowing air forward and blowing off smoke and dust forcibly, the field of view from the driver's seat 3 of the heavy equipment vehicle 1 to the vicinity of the tip of the arm 2b, which is a work place, is secured.

  The undulating and bendable arm 2 not only can move the chain-type mine blasting device 36 in the front-rear direction by refraction as shown in FIG. 14, but also can turn the swivel body 17 as shown in FIG. Therefore, the chain mine blasting device 36 can be efficiently moved without moving the heavy machinery vehicle 1 itself.

  As shown in FIGS. 16, 17 and 18, the rake 9 excavates mines in advance, collects unexplored mines, or excavates mines that cannot be removed by the flail hammer 34 to a depth of 50 cm. Can do.

  Landmine fragments crushed by the explosion are collected by a magnet 47 as shown in FIGS. At this time, as shown in the drawing, the cylinder of the magnet lifting device 48 is extended to lower the magnet 47 so that the magnet 47 can be easily brought close to the ground.

  As confirmation after mine disposal work, a detector is used to check if there are any remaining landmines, etc. throughout the treated area for safety confirmation. As a result, it is confirmed that the processing in this area has been performed reliably.

  During the mine blasting, the damper 41a absorbs the impact of the blast due to the explosion of the mine, so that the guard plate 32 and the chain-type mine blasting device 36 can avoid the impact, and the rake 9, magnet 47 and magnet behind it can be avoided. The lifting device 48 can also avoid the impact. In particular, the damper 41a cushions the shock plate 32 from being tilted by the blast as a shock absorber.
