Japanese Patent No. 3678718

  As shown in FIG. 24, Patent Document 1 discloses a rotary cutter 9 that is detachably attached to the tip of an undulating and bendable arm 2 of a heavy machinery vehicle (base machine) 1 used in a shovel such as a backhoe. A rake grapple 26 is provided on the side of the rotary cutter 9 and provided with a movable comb blade that can be moved by a cylinder or the like with respect to the fixed comb blade. And a magnet 7 for supplying power to the heavy machinery vehicle with an operation switch is provided.

  A magnet 7 is provided on the side opposite to the rotary cutter 9. The magnet 7 is an electric type, and supplies power to a heavy machine vehicle (base machine) 1 used for a shovel such as a backhoe by an operation switch.

The magnet 7 is connected to a battery 16 serving as a power source for the heavy machinery vehicle (base machine) 1 via a control panel 17, and an operation switch 18 provided in the driver's seat (cabin) 3 is connected to the control panel 17, The switch 18 performs ON / OFF control of the magnet 7.

  In the figure, reference numeral 25 denotes a cable extending from the magnet 7 to the control panel 17. The cable is connected to the rotary cutter 9, which is an attachment, so that it can be attached and detached with a cord connector 19. The vehicle (base machine) 1 is entered.

  The magnet 7 has a cylindrical shape as shown in the figure, and a blade-like bracket 20 is projected in parallel with a gap, while a bracket-like holder 21 is provided on the side of the hood 24 of the rotary cutter 9. The bracket 20 is detachably coupled to the holder 21 with pins 22.

  The actual soil, cutting, chipping, weeding trees, shrubs, and bushes often contain metal pieces, metal parts, metal balls, etc., and if this reacts to the sensor, In many cases, expeditious landmine exploration is not possible. In addition, after destroying antipersonnel landmines, metal parts such as springs will be scattered, and this may react to the sensor part and hinder the exploration. The work can be done easily and quickly, and by removing unnecessary metal pieces and metal blocks that you do not want to react to the sensor unit or a separate detector, appropriate landmine exploration can be performed, and efficient landmine disposal It becomes possible.

  First, the vegetation is cut with the rotary cutter 9, the rake grapple 26 is used, and after this is removed, the direct current (24 v) of the battery 16 is energized to the magnet 7, and a strong magnetic field generated in the magnet 7 portion is used. Adsorbs iron, scrap, chips, etc. This is done by tilting the rotary cutter 9 and bringing the magnet 7 closer to the ground.

  Iron, scrap, chips, etc. adsorbed on these magnets 7 are transported to a predetermined position and demagnetized when they are demagnetized.

  Next, landmine exploration is carried out with a landmine exploration device, and clearing is performed with a rotary cutter 9 to process antipersonnel landmines. Antipersonnel mines are destroyed without exploding by the high-speed rotation of the rotary cutter 9, and fragments are released to the ground. Depending on the type, only the fuze may burst, but there is no effect on the device.

  As a confirmation after the processing work, for the safety confirmation by the above work, it is checked by a detector whether there are any remaining landmines or the like over the entire treated area. As a result, it is confirmed that the processing in this area has been performed reliably. Iron, scrap, chips and the like may be adsorbed by the magnet 7 before the check by this detector. As a result, it is possible to recover the springs of destroyed antipersonnel mines, and to remove obstacles to the check operation by the detector for remaining mines.

  As described above, the landmine treatment is performed in a step-by-step manner such as “weeding-detection-processing-confirmation” so that there is no remaining landmine by a reliable treatment work.

  As described above, Patent Document 1 uses an electromagnet for the magnet 7, and it is necessary to supply power to the heavy-duty vehicle with an operation switch or to secure power from a battery.

  Therefore, the magnetic force of the magnet 7 is naturally limited, and may be provided on the side of the rotary cutter 9, so that only a relatively small one can be provided.

The object of the present invention is to eliminate the inconvenience of the conventional example, and attach the magnet device to the tip of the undulating and refracting arm of a heavy machine vehicle that is used in an excavator machine such as a backhoe as an attachment alone without being combined with a rotary cutter or the like. Therefore, it can be configured as a relatively large apparatus, and a permanent magnet can be used as the magnet used for the apparatus. Moreover, although the permanent magnet is used, ON / OFF control for applying a magnetic force is performed on the excavator. An object of the present invention is to provide a magnet device for processing metal parts, metal balls , and metal pieces that can be operated from a seat.

In order to achieve the above object, the present invention according to claim 1 is a magnet device attached as an attachment to the tip of a undulating and bendable arm of a heavy machine vehicle used in an excavator, and is a bottom plate formed as a leveling plate. A cylinder that can be operated from the driver's seat of a heavy machinery vehicle is provided in the box-shaped hollow housing with the vertical direction, and a permanent magnet placed on the bottom plate of the housing is attached to this cylinder, and magnetic force is generated from the position where it contacts the bottom plate. It is possible to move up and down to a position that is spaced apart from the bottom plate, and the scale bar is raised from the permanent magnet and protrudes out of the box-shaped hollow housing. essential that the operation pinching provided movable comb to more movable cylinder over respect rake or fixed comb is provided with a rake grapple possible It is an.

  According to the first aspect of the present invention, the magnet device is not an accessory, but can be attached to the tip of a undulating and refracting arm of a heavy machinery vehicle used in an excavator as a single main attachment. Can be configured. Moreover, a big and powerful magnet can be provided by using a permanent magnet.

  At the position where the permanent magnet is in contact with the bottom plate, the magnetic force extends outside the bottom plate, and is attached to the cylinder and separated upward from the position where it contacts the bottom plate to reduce the magnetic force outside the bottom plate. ON-OFF is possible.

  Moreover, the position of the permanent magnet inside the box-shaped hollow housing can be visually observed from the driver's seat by the scale rod.

Further, the bottom plate of the box-shaped hollow housing can be moved so as to level the ground by bringing the bottom plate close to about 50 to 100 mm on the ground surface to adsorb iron, scrap, chips and the like.

In addition, shrubs felled by rake grapples can be removed, and unexploded shells that have been discovered can be transported and eliminated.

As described above, the metal device for processing metal parts, metal balls , and metal pieces of the present invention is a single attachment that can be attached to the tip of a undulating and refracting arm of a heavy machinery vehicle used in a shovel machine such as a backhoe. Because it is independent, it can be configured as a relatively large device, and the magnet used for it can be a permanent magnet, so that it can obtain a strong magnetic force without using electricity from a battery or generator, and it can be used permanently. Although it is a magnet, ON / OFF control for applying a magnetic force can be operated from the driver's seat of the shovel machine.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a side view of a heavy machine vehicle (base machine) 1 to which a metal device, a metal ball , and a metal piece processing device of the present invention are attached as an attachment, and FIG. 2 is a partial plan view of the heavy machine vehicle (base machine). 1 is used, but the heavy machinery vehicle 1 is provided with an arm 2 that can be bent and bent freely. 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 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 the tip thereof is shown in FIG. 11 as an attachment that can be attached and detached with a pin 6 at the tip of the link mechanism 5a. Thus, the rotary cutter 9 can also be attached.

The rotary cutter 9 is provided with a cutter holder welded to the peripheral surface of the rotary drum, and a cutter bit made of carbon steel is planted at an appropriate interval through the cutter holder. Is coupled to the rotating shaft of the rotating drum, and a part of the lower side protrudes from the inside of the hood. As an example, the outer diameter of the excavation is φ900 mm to φ800 mm, the rotational speed is 500 to 650 rpm, the torque MAX is 128 kg · m, the cutting speed (tip) is MAX85 km / h to MAX 110 km / h, blade tip excavation force 284 kg to 319 kg, rated pressure 280 kg / cm ² , rated flow rate 165 to 210 liters / min, rated output 107 kw, cutter 1400 kg to 2000 kg, depth of about 30 cm or more, up to about 50 cm It shall be cut.

Similarly to the rotary cutter 9, the magnet device for processing metal parts, metal balls , and metal pieces according to the present invention is attached to the tip of the undulating and bendable arm 2 of the heavy machinery vehicle 1 via a link mechanism 5a as an attachment. A permanent magnet (magnet) 13 is provided in a box-shaped hollow housing 12 having a bottom plate 11 so as to be movable up and down.

  The box-shaped hollow housing 12 is a substantially rectangular steel box, on which a flange 15 provided with two engagement holes 14 for attaching and detaching the pin 6 is juxtaposed, and the side surface in the front-rear direction is doubled as a hollow side wall 27. Form on the side wall. This improves the protection.

  Further, the bottom plate 11 was formed in a bowl shape for leveling by flipping up the front and rear edges. The bottom plate 11 is formed of a thick steel plate, and a similar thick steel plate is also disposed as a protective plate 28 on the lateral side.

  The inside of the box-shaped hollow housing 12 is a flat quadrangular space, and the permanent magnet (magnet) 13 disposed here is also a flat flat quadrangular shape.

  A cylinder 30 that can be operated from a driver's seat (cabin) 3 is provided on the top plate 29 of the box-shaped hollow housing 12 in the vertical direction, and the rod 30a of the cylinder 30 is positioned in the housing 12, and the above-mentioned cylinder 30 is disposed at the tip thereof. The center of the upper surface of the permanent magnet (magnet) 13 was hingedly coupled by pin coupling. In this way, the permanent magnet 13 placed on the bottom plate 11 of the housing 12 can move up and down from a position where it abuts against the bottom plate 11 by the cylinder 30 to an upper spaced position where the magnetic force is reduced outside the bottom plate 11.

  Further, before and after the permanent magnet 13, a touch stopper 31 that slides inside the hollow side wall 27 is raised, and a suspension fixing bar 32 is raised at an inner position thereof. The contact stopper 31 and the suspension fixing bar 32 are permanent magnets. When 13 is in the ascending position, it comes out on the top plate 29 through a hole formed in the top plate 29.

  The contact stopper 31 is provided with a circular tube 33 in two vertical stages on a vertical plate and makes point contact with this peripheral surface to reduce frictional resistance.

  The suspension fixing bar 32 is provided with a pin hole at the tip thereof, which is matched with the pin hole of the latching flange 34 raised on the top plate 29 and can be fixed by the insertion pin.

  Further, the scale bar 35 was raised from the permanent magnet 13 and penetrated through the top plate 29 so as to protrude out of the box-shaped hollow housing 12. The vertical position of the permanent magnet 13 in the box-shaped hollow housing 12 can be confirmed by observing the protruding length of the scale bar 35 from the driver's seat (cabin) 3.

  On the rear side of the box-shaped hollow housing 12, a movable comb blade 26b that can be moved by a cylinder or the like with respect to the fixed comb blade 26a is provided to project a rake grapple 26 that can be sandwiched.

Next, how to use the magnet device for processing metal parts, metal balls , and metal pieces of the present invention will be described. When using landmine disposal equipment (system) in a place where landmines are expected to be based on the results of preliminary surveys of various information, advance work preparation is necessary for the efficiency of the overall work.

  First, after confirming the work position and setting the work section, the heavy-duty vehicle 1 moves forward and backward with the crawler belt 4 and the wheels, and turns. An operator rides on the driver's seat 3, and trees, shrubs, bushes, and grass that cover the ground surface with the rotary cutter 9 by the undulating and refracting arm 2 interfere with detection work and processing work such as landmines, and these are removed in advance.

Next, the attachment of the tip of the arm 2 is replaced from the rotary cutter 9 to the magnet device for processing metal parts, metal balls , and metal pieces of the present invention, and the cylinder 30 is extended to lower the permanent magnet (magnet) 13 and move onto the bottom plate 11. Put on.

  In this way, the magnetic force of the permanent magnet (magnet) 13 can be exerted outside the bottom plate 11, and iron, scrap, chips and the like are adsorbed by the generated strong magnetic field. This is done by bringing the bottom plate 11 of the box-shaped hollow housing 12 closer to the ground. The permanent magnet 13 has a magnetic force of 1,500 G and can adsorb two 30 kg pins simultaneously.

  Iron, scrap, chips, etc. adsorbed on the bottom plate 11 are transported to a predetermined position and, for example, as shown in FIG. 9, the arm 2 is swung to the position of a tray 36 provided on the heavy machinery vehicle 1 or shown in FIG. If the cylinder 30 is reduced as described above, the permanent magnet (magnet) 13 reduces the magnetic force outside the bottom plate 11 from the position where it abuts the bottom plate 11 and hardly exerts it. As a result, the magnetic force outside the bottom plate 11 is demagnetized, and iron, scrap, chips, etc. adsorbed on the bottom plate 11 fall on the tray 36.

  The rake grapple 26 is used, for example, when the trees, shrubs, bushes, and grass that cover the ground surface that obstruct landmine detection and processing operations are removed with the rotary cutter 9, the cut vegetation is 10 cm or less on the ground. Accumulated in height, or removed when shrubs are highly collapsed, or if unexploded shells are found, they are scooped up safely by the rake grapple 26 and removed to the rear of the machine body. Transported and processed.

  FIGS. 11 to 14 show a second embodiment of the present invention. The cylinder 30 provided in the vertical direction as operable from the driver's seat (cabin) 3 is provided in the box-shaped hollow housing 12. And provided on the outside left and right respectively.

  By providing the cylinders 30 on the left and right in this way, the permanent magnet 13 can be supported from the left and right to move up and down in a horizontal state, the touch stop 31 is not required, and no fixing by the suspension fixing bar 32 is required.

  Moreover, in this 2nd Embodiment, the baseplate 11 was made into the box shape instead of the hook shape by making the front and rear edges into a right angle.

  FIG. 23 shows a heavy machinery vehicle (base machine) 1 to which the second embodiment is attached.

  FIGS. 15 to 18 show a third embodiment of the present invention. As a modification of the second embodiment, a rake 37 is provided on the front side of the box-shaped hollow housing 12 instead of the rake grapple 26. This rake 37 is used for excavation and tilling.

  19 to 22 show a fourth embodiment of the present invention. As a modification of the third embodiment, a cylinder 30 provided in the vertical direction as operable from the driver's seat (cabin) 3 is shown as follows. Instead of providing them on the left and right sides of the box-shaped hollow housing 12, one is provided inside as in the first embodiment.

  The touch stopper 31 and the suspension fixing bar 32 described in the first embodiment are eliminated and a slide flute is adopted.

  The above embodiment has been described for the case of processing metal parts, metal balls, and metal pieces that are obstacles to landmine exploration in landmine processing scenes, etc., but the present invention is a general scrap processing, metal parts, It can also be applied to the case of effectively transporting or removing metal or the like.
