Definitions
- the invention relates to a device for the rescue of explosive objects located in the ground, such as mines, grenades or bombs, with a mobile device on which a digging device is arranged.
- Explosive objects are not only found in mined areas in war zones, but also everywhere where, for example, unexploded bombs from the Second World War have so far remained undetected. But also at earlier military sites there are sections of land that cannot be used without clearing mines or the like. To do this, it is necessary to dig the soil to a predetermined depth and to sort out the explosive objects.
- Trench cutters are already known with which excavation in the form of a trench can be carried out.
- the trencher is pivoted at the rear end of a vehicle about the axis of the chain drive wheel, so that the trencher can be moved from a rest position into a working position and vice versa.
- the trencher engages in the ground in an inclined position, the guide wheel being pivoted away from the vehicle.
- the chain milling machine is thus inclined in the working position against the direction of travel. Swiveling the idler wheel towards the vehicle is generally not possible.
- the trencher To move to the rest position, the trencher is simply swiveled upwards about the swivel axis until the idler wheel is above the surface of the earth.
- the tools are designed so that the soil is thrown out of the trench, which sometimes requires additional equipment.
- a tiller for agricultural soil improvement in which several juxtaposed, endless round horizontal deflection axes chains are provided, which are equipped with digging tools, one of the deflection axes being lowered into the ground in a vertical plane.
- This tiller is also located behind the vehicle and only serves to loosen the soil.
- Such soil or trench cutters are not suitable for the recovery of explosive objects because the extracted soil is either thrown off immediately behind the trench cutter or is heaped up next to the trench. There is therefore no possibility to search the extracted soil for any objects.
- a milling drum likewise arranged behind the vehicle, is known from G 94 06 207.2, which is driven counter to the direction of pull of the vehicle.
- the soil conveyed by the milling drum is fed to an adjustable screening device which is arranged behind the milling drum, so that the screened material falls back onto the milling track. With this device there is a risk that the vehicle will explode a mine or the like before the milling drum can dig out the object.
- the milling drum is arranged in front of the vehicle, but the milling drum with the associated stem is designed to cause the mines to explode anyway.
- the digging device is a chain cutter arranged on the front of the mobile device or a conveyor beam, the digging device being inclined towards the mobile device, and in that the digging device is arranged on the mobile device sorting system for separating the explosive objects and of the soil.
- Attaching the digging device in front of the mobile device offers the advantage that the trench can be dug in front of the mobile device in the direction of travel and, if necessary, filled in again behind the vehicle with the cleaned soil. Continuous combing of the soil is thus possible without the need for intermediate storage.
- the transport and the separation device are integrated, which continuously free and collect the earth excavated from the digging device from the explosive objects.
- the mobile device Since great propulsive forces are required when breaking up the ground, it is advantageous if the mobile device is a crawler vehicle. A wheel undercarriage can also be used if the ground conditions allow it.
- the digging device preferably extends at least partially over the mobile device.
- the angle of inclination of the digging device is preferably adjustable, as a result of which the trench depth can be set.
- the digging device should extend so far over the mobile device that the conveyed material can be thrown off in such a way that it can be fed to the sorting system without additional devices.
- the chain milling machine's digging tools are preferably hook-shaped cutting tools.
- the drives for driving and chain speed are preferably infinitely variable and hydrostatically adjustable. It is thus possible to determine the processing intensity and thus the fineness of the soil in the soil heaped up in front of the chain milling machine by coordinating the driving speed and chain speed. This has the further advantage that sensitive bomblets or mines usually detonate in this heaped-up area in the state surrounded by the soil, which generally does not cause any or only minor consequential damage.
- the conveying capacity can also be adjusted by coordinating the driving and chain speeds.
- the digging device comprises a conveyor beam that executes a rotational movement. At its lower end, with which it penetrates into the soil to be extracted, it has at least one cutting edge.
- a conveyor staircase is provided on its top, on which the extracted soil moves from stage to stage to the end of the conveyor beam due to the rotational movement.
- the sorting system comprises, inter alia, a transport device arranged downstream of the digging device, which is preferably run at a higher speed than the digging device, so that the extracted soil is pulled apart and thus better distributed on the transport device.
- the earth and material layer on the transport device is thus thinner than the material layer on the digging device. This ensures that the explosive objects to be sorted out are largely exposed and are not covered by the ground.
- the explosive objects usually have a ferromagnetic metal housing, they can be removed from the ground by means of a magnetic animal device. This requires that the components of the transport device consist of non-magnetic materials.
- the transport device is arranged so that it begins in the discharge area of the digging device and extends over the rear end of the mobile device. Since the sorting device is preferably arranged in the area of this transport device or is a component of the transport device, the cleaned soil, which has been freed from the explosive objects, can be thrown behind the mobile device.
- the transport device can have at least one elastic conveyor belt with two deflection rollers.
- An elastic conveyor belt is therefore necessary so that the soil thrown away by the digging device, in which the explosive objects are located, is cushioned when it hits the transport device. This can significantly reduce the risk of explosion of the explosive objects.
- the rear deflection roller of the conveyor belt is preferably a magnetic deflection roller.
- metallic components of the ground and thus also the explosive objects are fixed on the conveyor belt until the remaining non-magnetic material has already been dropped.
- the magnetic components of the soil are held on the conveyor belt up to the underside of the transport device and only separated from the conveyor belt in the area in which the conveyor belt is increasingly moving away from the magnetic deflection roller due to the weakening magnetic effect. They then fall from the conveyor belt into one arranged under the transport device Collecting device, which can consist of a container or another conveyor belt arranged transversely to the transport device.
- a sorting rake can also be arranged in the discharge area of the conveyor belt of the transport device, with which larger objects, such as e.g. Bombs, non-ferromagnetic parts or the like, can be sorted out, for which the force of the magnetic deflection roller may not be sufficient to fix these objects on the conveyor belt until the area of the collecting device is reached.
- a collecting device for collecting the sorted objects is also assigned to this so-called rake.
- the container can also be omitted so that the parts separated by the sorting rake fall directly onto the surface of the floor and can be collected from there if necessary. Without the sorting rake and container, only the ferromagnetic parts are discarded.
- the screened earth can also be deposited on a conveyor belt equipped with a reversing circuit, either on the right or left of the lane.
- a sorting roller is arranged above the conveyor belt in the area of the rear deflecting roller and rotates essentially at the same speed as the conveyor belt.
- This sorting roller can be magnetized in sections, only a circular sector of the sorting roller located above the conveyor belt being magnetized.
- the magnetic components in the ground are picked up and first fixed to the sorting roller. Due to the rotation of the fixing roller, the metallic components get into a non-magnetized area of the sorting roller and then fall off from it.
- An appropriately arranged collecting container holds the sorted out metallic objects. Any soil on the sorting roller is transported back onto the conveyor belt.
- an anti-ferritic transport bar can also be provided, which preferably has a conveyor staircase made of elastic material on the upper side.
- the magnetic sorting device is arranged above this transport bar and has at least one sorting disk which can be rotated about an axis arranged perpendicular to the transport bar and which can also be magnetized in regions.
- This disc is arranged so that most of the disc is above the transport bar and a smaller area of the disc next to the transport bar. Accordingly, the area of the sorting disc located above the transport bar can be magnetized and the area located next to the conveyor belt cannot be magnetized.
- the rotation of the disc takes up the metallic material and throws it into a corresponding collecting device next to the conveyor bar.
- a discharge plow can be provided over the conveying side of the digging device, with which large objects can be deflected laterally and dropped next to the device. This can be advantageous for very large bombs, tree stumps and stones, for example, because these could possibly block the entire device in the area of the sorting system.
- At least one suction proboscis is arranged in front of the undercarriage and is connected to a mass spectrometer located on the mobile device. It is therefore possible to detect any toxic substances in the ground so that appropriate countermeasures can be initiated.
- a proboscis can preferably also be arranged in the discharge area of the digging device, because the soil is already so finely distributed in this area that toxic substances are more easily accessible and detectable. Since the recovery of explosive objects is associated with a certain danger, the entire device can be controlled remotely.
- the sorting system can be removed from the mobile device and can be used as a stationary system.
- the sorting system is preferably equipped with a conveyor table which has an oscillating and tilting device.
- An excavator is used to load the feeding table and thus the sorting system.
- a vibrating or drum sieve can also be installed upstream of the conveyor table.
- the sorting system can be housed as an independent unit, for example in a commercially available container that has its own chassis.

- FIG. 7 a side view of a sorting plant as a stationary plant
- FIG. 8 shows a sorting system according to a further embodiment
- Figure 12 shows a sorting system in rear view.
- the mobile device 51 has a tracked vehicle 1 with a hydrostatically driven crawler loader or bulldozer.
- a vehicle frame 2 On the chassis 1, a vehicle frame 2 is attached, which carries a digging device 52 and a sorting system 53, which includes various additional devices. These include the remote control 12 and the vehicle orientation system 13.
- the digging device 52 is a chain cutter 54 which has a turas 11 with a hydrostatic drive 10 at the upper end and an adjustable stator 9 at the lower end.
- the hydrostatic drive 10 and the stator 9 are connected to one another via a frame 55, which in turn is articulated to the vehicle frame 2 via a support frame 56.
- the chain milling machine 54 is pivotally mounted about the upper pivot point 3, the angle of inclination being set by extending and retracting the hydraulic cylinder 35, which engages the support frame 56 at the lower pivot point 4. This means that different soil formations can be taken into account.
- the chain milling machine 54 has a revolving chain 57 with the chain links 5, which are explained in more detail in connection with FIG. 3.
- the chain 57 also runs over rollers 8 and support rollers 7.
- the chain milling machine 54 has a length such that it extends over the mobile device 51, so that the extracted soil can be dropped over the mobile device 51.
- the inclination and direction of rotation of the chain cutter 54 are selected such that the ground material, which is comminuted, on the top 58 of the chain cutter is transported upward.
- the fineness of the soil picked up is adjusted by coordinating the tool shape, the driving speed and the chain speed.
- the sorting system 53 has a transport device 15 with the deflection rollers 19, 20 and a conveyor belt 59.
- the transport device 15 is arranged below the discharge area of the chain milling machine 54, so that it can receive the soil conveyed by the chain milling machine 54.
- the belt speed of the transport device 15 is higher than the chain speed of the chain milling machine, so that the conveyed material is pulled apart and the layer thickness on the conveyor belt 59 is reduced to such an extent that the metallic components 17, 25 are largely exposed.
- the conveyor belt is made of elastic material, so that the explosive objects 17, 25 are cushioned.
- the rear deflection roller 19 is designed as a magnetic roller so that the smaller ferromagnetic components 17 can be held in place during the deflection and separated from the rest of the earth.
- the metallic components 17 only fall off the conveyor belt 59 when the conveyor belt 59 has moved a certain distance from the deflection roller 19.
- the metallic components 17 are collected by a collecting container 21.
- the soil, together with the large components 25, which can be stones, bomblets, splinters and the like, is thrown behind the mobile device 51 and hits a sorting rake 22 there, which sorts out the coarse components.
- the screened earth 18 falls back into the trench and the sorted out coarse constituents pass into another container 26, where they are collected.
- the sorting rake 22 and the container 26 are attached to a rocker 24, the sorting rake 22 being moved by an eccentric drive 23 so that it performs a rotational movement.
- conveyor belts (not shown) arranged transversely to the longitudinal axis of the device can also be provided, so that the explosive objects can also be deposited to the side of the trench.
- a further transversely arranged conveyor belt can also be provided in the discharge area of the transport device 15, so that the cleaned soil can be deposited laterally next to the trench. This makes it possible to detect the exposed, deeper surface in a second operation. So that no conversion measures are necessary when the device processes the connection track underneath during the return journey, the transversely arranged conveyor belts project so far from the chassis 1 that a lateral storage is possible on both the right and the left side of the device. This also requires a reversing circuit to change the direction of rotation.
- a suction nozzle 16a is furthermore arranged between the chain milling machine 54 and the undercarriage 1 near the ground, with which air is sucked in.
- the pollutants contained in the air are fed via the suction nozzle 16 to a mass spectrometer 14 arranged on the mobile device 1, where an analysis of the components is carried out immediately.
- An additional suction nozzle 16b can be arranged in the discharge area of the chain milling machine 54.
- FIG. 2 which differs from the device shown in FIG. 1 in that the attachment of the chain cutter 54 to the vehicle frame 2 is carried out differently. While the pivot point 3 according to FIG. 1 lies outside the chain milling machine, the pivot point in the embodiment shown here is identical to the pivot point of the Turas 11.
- the chain milling machine 54 has on its upper side 58, at a distance from the digging tools 60, a throwing plow 47 with which large objects 25 such as stones, larger explosive objects or the like can be deflected to the side and thrown off next to the trench.
- a sorting roller 43 is provided, the speed of rotation of which is adapted to that of the transport device 15.
- the area 44 above the transport device 15 can be magnetized so that the ferromagnetic components 17 can be removed from the ground.
- the sorting roller 43 is pivotably mounted about the axis 61 so that it opens the soil layer located on the conveyor belt 59 rests.
- An armored housing 40 is provided above the transport device 15, in which the drive motor 33, the hydraulic system 34, the hydrostatic 36, the hydraulic control 37, the electrical control 38, the remote control 41 and one or more television cameras 42 are accommodated.
- FIG. 3 shows a digging tool 60 which acts over the entire working width and which is screwed onto a chain link 5.
- the base plate 6, which is part of the chain 57, has a shoulder 62 on which a Cutting tool 50 is welded.
- the extension 62 and the cutting tool 50 together form the hook-shaped digging tool 60.
- FIG. 4 shows a further embodiment which has a conveyor bar 63 instead of a chain milling machine 54.
- This has a cutting edge 64 at the lower end, with which the conveyor bar 63 digs into the ground.
- the upper side 58 of the conveyor bar 63 is provided with a conveyor staircase 65, on which the soil continuously moves upwards due to the rotational movement of the conveyor bar 63 until it reaches the discharge area of the conveyor bar.
- the rotational movement is effected via an eccentric mechanism 66 fastened to the conveyor bar 63, which acts on the underside of the conveyor bar 63 and is fastened to a support bar 76.
- the rotational movement takes place in the direction of the arrow.
- the transport device 15 also has a transport bar 67 with a conveyor staircase 68.
- the transport bar 67 receives the material thrown off the conveyor bar 63 and also transports it due to a rotational movement in the direction of the arrow to the rear end of the device, where the cleaned soil is thrown off.
- the rotational movement of the transport bar 67 is stronger than that of the conveyor bar 63, so that the soil on the transport bar 67 is pulled apart and distributed.
- the sorting device with two rotating sorting disks 69 is arranged above the transport bar 67.
- the sorting disks 69 can be rotated about the vertical axes 70 and have magnetic rings 71 on the underside, which faces the transport device 15.
- the ferromagnetic components are removed from the soil lying on the transport bar 67 by means of the magnetic rings 71.
- the transport bar 67 consists of non-magnetizable material. 14
- the arrangement of the sorting disks 69a, b is shown in FIG. 5.
- the sorting disk 69b with the magnetic ring 71b is arranged above the left half of the transport bar 67.
- a further sorting disk 69a with a magnetic ring 71a is provided above the right half.
- the two sorting disks 69a, b are arranged such that they protrude laterally relative to the transport bar 67.
- the magnetic rings 71a, b are demagnetized, so that the components hanging on the magnetic ring can be thrown into the corresponding collecting containers 73, 74.
- the separation takes place with the aid of two conveyor belts 80, 81.
- the first conveyor belt 80 is responsible for the separation of the iron parts.
- the upper deflection roller is designed as a magnetic roller 19.
- the conveyor belt 80 runs much faster than the chain milling machine 54, which is why there is only a few cm thick layer of earth when transporting the soil.
- the extremely strongly dimensioned magnetic roller 19 is thereby able to attract all iron parts located in the floor and to pull them against the belt during the deflection. The further the iron parts move away from the magnetic roller 19 after the deflection, the smaller the holding force.
- This arrangement is particularly suitable for earth, stones, wood residues, bomblets and ammunition made of non-ferrous metals, mines made of plastic, etc., which generally makes the separation very difficult.
- the separation of these very different parts and materials takes place in the first phase with the aid of an optical or inductive detection device 85, 84, the signals of which are forwarded to approximately four pneumatically operated flaps 82 which, after being folded over, open the earth current together with the ammunition contained therein guide the cross conveyor belt 86, which in turn releases this laterally into a collection box.
- optical detection device or signal generation which is primarily responsible for all non-metallic bodies, a wide variety of geometric parameters are entered and stored in an evaluation system coupled to a television camera.
- the inductive detection device 84 is responsible for all metallic bodies and also controls the corresponding pneumatically operated flap 82 in the direction of the cross conveyor belt 86 when corresponding bodies enter the effective area.
- Conveying earth during the separation has disadvantages in terms of the separated volume, but also the advantage that the earth has a dampening effect on the impact of the bomblets.
- a separation between contaminated and non-contaminated material can also be carried out with a mass spectrometer in the event of chemical contamination.
- the device can also be used as a stationary system. For this purpose, the entire device is set into the ground and sunk for separation material poured into the funnel-shaped trough. The soil freed from ammunition can then be removed and distributed conventionally.
- a conveyor table 92 with an oscillating and tilting device is installed in the front area of the sorting system.
- an excavator 88 is used for the loading under these conditions.
- the latter is able to transport the complete sorting system and, after carefully digging it out with its backhoe 89, can tip the earth together with the ammunition onto the conveyor table 92, which is surrounded by protective plates 93.
- the conveyor table 92 which is open at the top, has an oscillating and tilting device, by means of which inclination and vibrations enable a uniform feed to the conveyor belt 80.
- the earth layer thickness on the conveyor belt 80 is then in turn determined via the belt speed.
- the separated parts can be removed laterally according to FIG. 7 with conveyor belts or according to FIG. 8 with containers.
- fenders 94, 97 are fitted on the right and left and on the front side, so that here too there is an opening only in the event of a detonation.
- the complete system can be monitored and controlled by a camera 42.
- the backhoe that goes forward works open and has an additional protective shield 90, prevents splinters from escaping towards the driver's cabin in the event of detonations.
- a protective screen 91 made of bulletproof glass is fastened in front of the cab with the aid of a holding frame.
- the system can also be monitored and controlled remotely by television 42.
- the sorting system 53 shown in FIGS. 9 to 12 is installed in a removable container with a container frame 101 and is loaded on a 2-axle trailer 102.
- the sorting system 53 can be operated standing on the trailer as well as on the ground.
- the excavator 88 moves into such a position that it reaches the loaded area on the one hand, and the vibrating sieve 103 with its bucket 104 on the other hand, in the form of a funnel.
- the vibration of the screen 103 is achieved via an eccentric drive 108 on the one hand and the rocker arm 107 on the other.
- a hinge 123 is provided as a link between the slides 122 and 124, so that the slide 124 can be folded out.
- the excavator can distribute it again.
- the material to be sorted slides to conveyor belt 110, which in turn has a magnetic roller 111 and sorts out the iron parts and feeds it to cross conveyor belt 115, which is responsible for the lateral removal according to FIG. 13.
- the rest of the material falls on the belt 112, which is also equipped with a magnetic roller, which has the task of safely sorting out the remaining iron parts or projectiles, etc.
- the conveyor belts 113, 114 oriented to the side ensure separate removal from the side.
- the system can be switched off via an emergency shutdown on the basis of optical detection using a television camera 42. Separation according to FIG. 6 is also possible.
- Another advantage is that, in the event of a detonation in the container which is open at the top, the hanging mats fold down to the outside to a limited extent and thus a greater build-up of pressure is largely avoided.
- the same protective measures are provided on the trailer frame with corresponding rubber mats 125 and holding strips 126.
- the eccentric drive 108 is displaceable to change the inclination of the vibrating screen 103.
- the system has its own power supply 116, controller 117 and power distribution 118 and can be remotely controlled in terms of belt speeds, vibrating screen frequency and start and stop.
- the system according to FIG. 10 is basically the same as that of FIG. 9.
- a second conveyor belt is dispensed with if there is knowledge that only iron-containing ammunition is buried in the ground to be worked or because other explosive objects are observed by watching the conveyor belt 130 by means of a television camera 42 can be located.
- a separating plate 120 is provided for separating Fe parts and the other constituents.
- the separation is carried out with the aid of a non-magnetizable, for example rotating plastic drum 132 and a sector-specific magnet 133.
- the same effect occurs as with the magnetic roller of a conveyor belt.
- a raised, extended, closed bottom 134 is necessary.
- two such drums could also be provided one behind the other.
- Cross conveyor belts 130, 131 are also provided here.
