Definitions
- the invention relates to a mine clearing vehicle with a front attachment, which is hydraulically or pneumatically operated cylinder-piston assemblies and, if necessary, pivotally hinged to the vehicle frame legs operatively connected to the vehicle and an at least downwardly open or at least partially has an open box in which a preferably hydraulically rotationally driven first milling drum is arranged essentially transversely to the direction of travel.
- bulldozers vehicles of the type in question have been known in practice which, in terms of their basic structure, can be referred to as bulldozers 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 clear roads.
- Vehicles or bulldozers of the type in question are among others also used to cultivate 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 vehicle claimed here is now a mine-clearing vehicle with which, for example, mines, rifle mines and tank mines can be conveyed out and cleared from a depth of up to about 30 cm below the surface of the ground.
- mine-clearing vehicle When using such a mine-clearing vehicle, it is particularly a matter of removing "forgotten" mines, which, because of the danger potential, poses particularly significant problems.
- a mine clearing vehicle of the generic type has already been developed by the applicant. For this, reference is made to EP 0 618 423 A1. This well-known mine clearing vehicle is ideally suited for clearing hidden mines, with the milling drum rotating counter to the direction of travel.
- 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 the mines once captured by the milling drum are safely detonated in a protected or encapsulated area.
- the generic mine clearing vehicle is designed in such a way that in the area behind the first milling drum there is a second milling drum, which is arranged at a distance and with its axis of rotation essentially parallel to the first milling drum, preferably hydraulically driven.
- a second milling drum significantly increases the probability of a safe detonation of the mine in the front region of the front attachment.
- a second milling drum is provided, which is arranged at a distance from the first milling drum.
- the axes of rotation of the two milling drums are aligned essentially parallel to one another, so that lateral extraction of undetected mines is effectively avoided. Otherwise, the area between the two milling drums lies within the front attachment, so that it is not possible to convey them out laterally because of the side walls.
- the two milling drums are arranged at a distance from one another, so that the mines picked up by the first milling drum are conveyed into the front attachment or box and picked up there by the second milling drum while the clearing vehicle is moving and detonating due to the pressure which arises in the process to be brought. At the same time, any parts are shredded, so that this process also serves to recultivate the soil that has been milled through to this extent.
- the two milling drums are preferably driven hydraulically. It is particularly advantageous if the first - front - milling drum rotates more slowly than the second milling drum arranged behind the first milling drum. In this respect, the material or soil brought into the area of the front attachment by the first milling drum is further milled or crushed and distributed as quickly as possible.
- the first milling drum is advantageously at a rotational speed of up to approximately 100 rpm and the second Milling drum can be driven to a speed of up to about 500 rpm. The respective rotational speed is regulated continuously.
- the two milling drums rotate in opposite directions, the first milling drum rotating in the direction of travel and the second milling drum rotating in the opposite direction.
- the soil and parts, including mines are conveyed from the first milling drum into the area of the front attachment.
- the soil and the parts contained therein are grasped by the second milling drum rotating counter to the direction of travel, mines not yet detonated being detonated due to the pressure between the two milling drums - in the soil.
- each part is shredded again and a further step is carried out to recultivate the soil.
- the front attachment can have any devices and measures for separating metallic parts.
- magnetic parts can be separated by very special magnet arrangements, so that the achievable soil quality is favored due to the probing of certain materials.
- the two milling drums are at a predetermined distance from one another. This distance is advantageously about 100 mm. Furthermore, it is essential that the axes of rotation of both milling drums can lie essentially on a common horizontal. If the first - front - milling drum has a larger diameter than the second - rear - milling drum, the first milling drum is forced to reach deeper into the ground than the second milling drum. As a result, the second milling drum provides an additional effect of smoothing the floor after very substantial intervention by the first milling drum. In this respect, the recultivation achieved at the same time is favored.
- the first milling drum has a diameter of approximately 1000 mm and the second milling drum has a diameter of approximately 500 mm.
- the axes of rotation of both milling drums can then have a distance of approximately 850 mm from one another.
- Other dimensions are conceivable, with a coordination between the diameter of the milling drums and their spacing from one another.
- both milling drums it is a further advantage if they are arranged together in the box of the front attachment. This would encapsulate both milling drums.
- the second milling drum could be arranged in a rearward extension of the box in the front attachment, the second milling drum also protruding downward at least slightly from this area of the front attachment. An intervention in the ground is thus guaranteed.
- the second milling drum could be arranged completely outside the box in a housing part which extends backwards from the box and opens into the box, this housing part also being part of the front attachment.
- both milling drums it is essential for both milling drums that they protrude at least slightly downward from the respective housing or box, so that an intervention into the ground is possible within a predetermined engagement depth.
- a height adjustment of both milling drums - manually or pneumatically or hydraulically - is conceivable.
- the inside of the box, above and preferably in the area is at least slightly behind the axis of rotation first milling drum, a pivotably suspended pivoting flap which extends substantially parallel to the axis of rotation of the milling drum and extends transversely through the box in the sense of a deflector, scraper or the like. Soil conveyed upwards by the first milling drum is thrown against this flap and from there falls back into the area behind the first milling drum.
- This flap can also be spring-loaded or pressurized, in the direction of one lower position. In this respect, it would be ensured that soil thrown up or parts carried along would actually bounce off the flap and in the area behind the first milling drum could actually be grasped by the second milling drum.
- this flap has an upper and a lower stop and rests on the lower stop in the rest position - due to gravity or pressure or spring action. If coarse or large-area parts lock in the area between the first milling drum and the flap, the flap is pushed up and the soil and parts reach the first milling drum and can be grasped there again and shredded from below into the area of the front attachment. A renewed possibility of detonating mines has thus been created.
- the flap can be swiveled by only 90 ° between the lower stop and the upper stop is.
- the flap is in contact with the upper stop as a guide element, so that falling back into the area behind the milling drum is largely excluded.
- the flap could be positioned or mounted in such a way that it rests at an angle of max. 90 ° to a horizontal imagined by the axis of rotation of the first milling drum.
- the flap in its position at the lower stop serves to reject the area behind the first milling drum and after overcoming the gravity of the flap or the pressure acting on it by any pressure medium, it is used for conveying into the area in front of the first milling drum, in which case a repeated gripping of the soil is guaranteed by the first milling drum.
- a device for catching or rejecting parts is arranged in a further advantageous manner. This device serves to intercept or reject the parts conveyed upwards or backwards by the second milling drum, so that these parts do not get under the mine clearing vehicle in an uncontrolled manner. In the case of a rigid arrangement of the device, the parts return after bouncing off of this device into the immediate effective area of the milling drum and are again detected and conveyed into the ground.
- the device is designed in the form of swiveling strips or swords which are arranged next to one another and which hang vertically downward in the rest position.
- the ledges or swords are essentially backwards, i.e. against the direction of travel, swiveling.
- the pivoting movement of the bars or swords could take place against the pretensioning of a suitable pressure medium, so that a predeterminable force would have to be overcome.
- the device could also be sharp-edged swords against which the second milling drum works. In this respect, the soil or the extracted parts could be further shredded.
- the swords are arranged in a row at a distance of 50 to 200 mm, preferably at a distance of 100 mm from one another.
- the swords would literally form a kind of curtain or protective grille.
- the swords could be arranged relative to the second milling drum in such a way that in their rest position they reach between the cutting and breaking tools of the second milling drum.
- the grinding or chopping of the soil and entrained parts would be favored again, which in turn contributes to the quality of the recultivation of the soil and the quality of the shredding or shredding of the picked up parts.

- the front attachment 1 comprises a box 5 which is open at the bottom and in which a hydraulically driven first milling drum 6 is arranged transversely to the direction of travel 7.
- a hydraulically driven second milling drum 8 is provided in the area behind the first milling drum 6 at a distance and with its axis of rotation essentially parallel to the first milling drum 6.
- the axes of rotation of both milling drums 6, 8 run parallel to one another, the axes of rotation of both milling drums 6, 8 lying on a common horizontal 9.
- the two milling drums 6, 8 rotate in opposite directions, the first milling drum 6 rotating in the direction of travel 7 and the second milling drum 8 rotating in the opposite direction to the direction of travel 7.
- the figures further show that the second milling drum 8 has a smaller diameter than the first milling drum 6.
- FIG. 2 shows very particularly clearly that within the box 5, above and in the area slightly behind the axis of rotation of the first milling drum 6, a pivotable suspended, parallel to the axis of rotation of the first milling drum 6 extending transversely through the box 5 pivoting flap 11 in A deflector or wiper is provided.
- the flap 11 has an upper stop 12 and a lower stop 13. In the rest position, the flap 11 lies on the lower stop 13.
- the flap 11 can be pivoted by approximately 90 "between the lower stop 13 and the upper stop 12.
- the flap 11 is positioned or mounted in such a way that in its rest position, ie resting on the lower stop 13, it forms an angle of approximately 90 ° to a horizontal line 9 imagined by the axis of rotation of the first milling drum 6.
- a device 14 for collecting or rejecting soil or parts, including mines or the like, is arranged directly behind the second milling drum 8.
- This device 14 is arranged essentially parallel to the vertical plane imagined by the axis of rotation of the second milling drum 8 and is designed in the form of swiveling swords 15 which are arranged next to one another and hang vertically downward in the rest position.
- a spacing between the swords 15 reference is made to the general part of the description in order to avoid repetitions.
- FIG. 2 shows that the swords 15 engage between the cutting and breaking tools 16 of the second milling drum 8 in their rest position. To this extent, interaction between the second milling drum 8 and the swords 15 or the device 14 is ensured.
