Definitions
- the invention relates to a mine clearing vehicle with a front attachment, which is operatively connected to the vehicle by means of hydraulically or pneumatically operating cylinder-piston arrangements and, if appropriate, by means of frame legs pivotably connected to the vehicle, and with one in the direction of travel forward and backward box at least partially open at the bottom with a preferably hydraulically rotationally driven Frästrom ⁇ mel, which is arranged essentially transversely to the direction of travel, rotates counter to the direction of travel, conveys the mine in front of the milling drum and there causes an explosion by pressure.
- Vehicles of the type in question designed in the sense of a bulldozer have been known from practice for some time and are generally used for soil cultivation. Due to their particularly robust construction, they can be used especially for heavy work in forestry. They are used to move or transport felled trees or to clear roads.
- Vehicles or bulldozers of the type in question are among others also used for the cultivation of soils.
- a milling drum arranged in a front attachment - in front of the actual tracked vehicle - is used for milling or combing through the upper layers of earth, whereby plants, trees, stones, etc. are crushed or broken up by the milling drum.
- the soil is circulated by the milling drum engaging in the upper layers of earth and the shattered wood, stones and the like are mixed with the soil.
- the claimed vehicle is now a mine clearing vehicle, with which preferably rifle mines and tank mines can be conveyed out and cleared from a depth of up to 30 cm below the ground surface.
- a mine clearing vehicle is particularly concerned with the removal of forgotten mines, for example in the area of old border installations on the so-called death strip of the former GDR.
- the present invention is therefore based on the object of designing and developing a mine clearing vehicle of the generic type in such a way that magnetic parts can be separated in virtually one work step with the clearing.
- the generic mine-clearing vehicle is designed such that a magnet or a magnet arrangement for receiving magnetic parts is arranged in the area in front of the milling drum.
- a device for demixing or separating magnetic parts can be assigned directly to the mine-clearing vehicle without impairing the actual function of the mine-clearing vehicle.
- a device can comprise a magnet or a magnet arrangement for holding magnetic parts.
- This magnet or this magnet arrangement is arranged in the area in front of the milling drum, so that the earth wall thrown against the direction of travel detects magnetic parts therein, in particular iron parts, and the iron parts by the magnet or by the magnet elements order can be pulled out.
- the magnet or the magnet arrangement is to be positioned in such a way that the milling drum ideally throws the soil containing the iron parts against the magnet or the magnet arrangement, so that the magnetic parts are actually securely adhered to the magnet.
- the magnet or the magnet arrangement has at least one cover directed downward.
- This cover could be designed as a magnetic plate, so that the effect of the magnet or the magnet arrangement takes place through the plate. It would also be conceivable to completely encapsulate the magnet or the magnet arrangement, the encapsulation being at least largely magnetic Material should exist. Here, too, an effect of the magnet through the capsule would be guaranteed.
- the magnet or the magnet arrangement it would be of particular advantage to arrange it in front of the box. It would also be conceivable for the magnet or the magnet arrangement to protrude from the outside into the box, namely until shortly before the milling drum. The entire arrangement could protrude diagonally forward from the box.
- the front attachment could preferably have hydraulically pivoting flaps on its front as a protective shield or for closing the box on the front. Accordingly, the magnet or the magnet arrangement could then be arranged under the flap, this flap being part of the above-mentioned collecting hood.
- the flap could be the back of the collecting hood.
- the flap or collecting hood could then be inclined obliquely forwards as a protective shield, preferably protruding upwards, whereby both an angular adjustment and a displacement of the collecting hood forwards or backwards into the box could be possible.
- the flap or collecting hood could be articulated within the box on two opposite side walls and the box could at least be largely closed by a downward pivoting movement.
- the box could be closed to detonate mines and could separate magnetic parts with the box open, i.e. take place with the catch hood swung out.
- the flap or collecting hood could be pivoted on the upper edge of the box and the box could be closed by a downward pivoting movement.
- the box for detonating mines could be closed and opened for the separation of magnetic parts, in which case the collecting hood has to be swung forward at an angle.
- the milling drum which extends into the soil and rotates counter to the direction of travel, passes the soil over the mine and would promote against the flap or the magnet or the magnet arrangement.
- the magnet or the magnet arrangement could be arranged at a height of 50 to 60 cm above the floor.
- the magnet With regard to a specific configuration of the magnet or the magnet arrangement, it is advantageous to design the magnet as an electromagnet. It would be advantageous if the magnet extends over the entire width of the milling drum and consists of at least two magnet groups, namely comprises two electrical coils. These coils would be fed via a generator, which is preferably assigned to the vehicle, and actuated from the driver's cabin. By variable loading of the coils, the effect or the magnetic fields and thus the attraction of the magnets can be changed, so that an optimal adaptation to the circumstances can also take place here.
- the box should be dimensioned such that it has at least the width of the bulldozer.
- the milling drum should therefore extend over the entire width of the box, so that the area in front of the tracked vehicle is plowed safely and the rifle mines and tank mines lying about 30 cm below the surface are definitely detected.
- the speed of rotation of the milling drum should be infinitely adjustable. In this respect, a very special adjustment can be made to the soil to be milled in each case.
- the direction of rotation of the milling drum could also be adjustable or reversible. This would have the very special advantage that when the milling drum rotates in the direction of travel, for example, mines or other non-destructible objects that cannot be exploded are conveyed out of the box or the area of the milling drum.
- the front attachment should have a preferably hydraulic flap serving as a protective shield on its front side.
- the flap could be oriented in the working position in such a way that it acts towards the driver of the mine clearing vehicle in the sense of a protective shield.
- the flap could also be used to close the front of the box, so that it is at least closed to the front during the mine search, so that explosions occurring inside or below the box are contained by the box.
- the flap in the case of a design of the flap as a protective shield, it could be inclined obliquely towards the front and be protruding upwards.
- the milling drum which engages in the soil and rotates counter to the direction of travel conveys the soil across the mine against the flap which is in the closed state. Since the milling drum preferably has cutting and / or breaking tools that are evenly spaced from one another on the circumferential surface, these can grasp the mine from below and explode in the earth conveyed in front of the milling drum due to the pressure exerted there on the mine by the milling drum. If it is not possible to destroy the mine extracted from the ground by explosion, the direction of rotation of the milling drum can be reversed, so that the mine that has not exploded is conveyed outside the box.
- the milling drum could be swiveled at least slightly in a horizontal plane, so that the soil can be conveyed out of the side of the box.
- the swivel direction and the swivel angle are adjustable.
- the box and possibly the flap are or are made of steel plates. These components are to be designed in such a way that they can withstand explosions such as those that occur in Panzer mines weighing up to 7.5 kg.
- FIG. 1 is a schematic side view of a mine clearing vehicle in the form of a specially designed bulldozer
- Fig. 2 shows the object of Fig. 1 in a front view
- FIG. 3 shows the object from FIG. 1 in the area of the front attachment in an enlarged illustration.
- FIG. 1 shows a mine clearing vehicle, which is more precisely a bulldozer.
- the vehicle shown here has a front attachment 1 which can be raised and lowered with the tracked vehicle by means of hydraulically operating cylinder-piston arrangements 2 and by means of frame legs 3 pivotably connected to the mine-clearing vehicle is connected.
- a box 4 open in the direction of travel forward and downward is provided with a hydraulically rotary driven milling drum 5 arranged transversely to the direction of travel. 1 and 2 together show that the box 4 has the width of the entire caterpillar.
- the milling drum 5 in turn extends over the entire width of the box 4.
- the milling depth can be adjusted by means of the box 4 or front attachment 1, pressing or lifting cylinder-piston arrangements 2.
- the front attachment 1 has a pivotable flap 7 serving as a protective shield on its front side.
- the flap 7 is inclined obliquely towards the front in the sense of a protective shield, namely, it projects upwards.
- the flap 7 could also serve to close the box 4 on the front side.
- the milling drum 5 has cutting and breaking tools 8 which are approximately uniformly spaced apart on the circumferential surface. 3 clearly shows that the mine 9, which is only indicated there, is gripped by the cutting and breaking tools 8 and caused to explode in the earth 10 conveyed in front of the milling drum 5 due to the pressure exerted there on the mine 9.
- the flap 7 is in a position forming a protective shield, the flap 7 could - if necessary - be closed during the explosion of the mine 9. This would effectively prevent scattering of splinters or the like.
- a magnet or a magnet arrangement 11 for receiving magnetic parts 12 is now arranged in the area in front of the milling drum 5.
- the magnet arrangement 11 has a downward-facing cover 13, which is designed as a magnetic plate.
- FIG. 1 and 3 show particularly clearly that the magnet arrangement 11 is arranged under the flap 7.
- This flap 7 is part of a collecting hood 14 which, as a protective shield, is inclined obliquely towards the front or can be fixed in a protruding manner upwards.
- the collecting hood 14 is inside the box 4 at two each other opposite side walls are pivoted so that the box 4 is at least largely closable by a downward pivoting movement.
- the magnet or the magnet arrangement 11 is designed as an electromagnet.
- the magnet arrangement 11 comprises two independent electrical coils 15, which are fed via a power unit 16 assigned to the vehicle.
- the electrical coils 15 or the magnet arrangement 11 can be actuated from the driver's cab, i.e. can be activated or deactivated.
