Definitions

  • the invention relates to an adjusting device of the cutting unit on a mining device which can be moved on caterpillars in opencast mining, the cutting unit being formed from at least one crushing and conveying screw interacting with a guide element and being articulated horizontally in front of the mining device by means of a suspension, and the broken material being from the outside can be transported to the center of the screw and can be transferred to a downstream conveyor through an opening provided in the guide element.
  • the loading elements are designed as screw conveyors, which can be swiveled arm-like on both sides of the conveying device with a supporting frame.
  • the screw conveyors are at least partially equipped with crushing tools on their screw web, the guide elements serving as crushing abutments in this area.
  • the support frames can be swiveled independently of one another about their vertical axes in order to ensure that the entire machine can move around curves.
  • the actual extraction organ is arranged in front of the screw conveyors, so that there is a separation between the extraction and removal processes.
  • Tunneling machines of the type mentioned are well suited for underground mining, where there are only low removal heights.
  • the actual extraction organs are connected upstream of the loading organs, so that the loading organs themselves only have to take up the cut material falling to the ground and possibly have to shred them.
  • the cutting unit is formed from at least one crushing and conveying screw which interacts with a guide element, the broken material being transported from the outside to the center of the screw and being transferred there to a downstream conveying means through an opening provided in the guide element.
  • the cutting units of both company brochures have in common that a continuous cutting and conveying process of the extraction organ is achieved.
  • the disadvantages of the cutting units described in the company brochures are essentially due to the fact that, depending on the diameter of the cutting unit, only very small rock layer heights can be detected in one operation.
  • the company brochure of the Paurat company (Senkhelix) a possibility of lifting the entire device is already described, whereby the continuity of the extraction process is interrupted by the option shown, since the caterpillars can no longer be moved. The material broken off at the top falls on the floor and may lead to difficulties in loading when lowering the cutting unit.
  • US Pat. No. 3,861,475 shows an earthworking machine or moving machine which has a chassis including a tire chassis with a roller body arranged behind it.
  • a soil cultivation device consisting of at least one screw and held in a frame, the frame being liftable on the one hand by means of a hydraulic cylinder and on the other hand being pivotable about a horizontal axis.
  • This device is only for loosening soil, be it for agricultural purposes or for road construction can be used with subsequent compression. Extraction, ie the cutting of layers of rock, as is done, for example, in open-cast mining, with the transfer of material to a discharge conveyor is neither provided nor possible here. Since this device is not suitable for extracting crushed rock on the ground, the height adjustment option or the possibility of pivoting the frame relative to the device can only be applicable to differently inclined ground conditions, so that a corresponding subgrade can be generated using this device.
  • the invention has for its object to further develop an adjustment device of the cutting unit described in the generic part of the main patent claim that in addition to the continuous cutting and conveying process, the cutting unit should also be usable for the dismantling of higher-lying materials. Furthermore, it should be ensured in all dismantling situations that the goods to be removed do not fall onto the ground when they are handed over to a conveyor arranged after the cutting unit, and so that the extraction device has to be moved back to collect the failed pile again. Furthermore, the construction of the extraction device in connection with the cutting unit and its employment should be simplified.
  • the features according to the invention ensure that a continuous cutting and conveying process can be implemented with a relatively simple structural design in any height or inclination position of the cutting unit.
  • the suspension preferably consists of a cross member and associated legs.
  • the cutting unit is pivotable about the axis extending between the free ends of the legs.
  • the relatively short lever arms formed in this way allow, on the one hand, a compact design and, on the other hand, easier lifting of the cutting unit around the horizontal axis.
  • At least one hydraulic cylinder which is articulated on the one hand on the cross member and on the other hand on an upward extension of the guide element can be used.
  • the conveying means is formed from a conveyor belt, the deflection of which on the cutting unit side is arranged almost coaxially with the axis.
  • the compact design is further improved by this measure, since the otherwise required separate deflection roller can be dispensed with, especially since it can be formed directly by the horizontal axis itself.
  • the horizontal axis in the region of the fork legs is preferably displaced by means of slide bearings in order to be able to absorb any transverse movements of the cutting unit without damage.
  • a surface mining device 1 which essentially has the following components: a crawler track 2 with a substructure 3, a superstructure 4 arranged thereon, a combined extraction and loading element 5, a guide element 6, a drive 7 for the extraction and loading element 5 , a suspension 8 for the extraction and loading member 5 and a conveyor 9 designed as a conveyor .
  • the extraction and loading element 5 is designed as a screw conveyor (not shown) which conveys in the opposite direction and is preferably equipped with breaking elements in the form of chisels or the like in the region of its outer peripheral surface.
  • the extraction and loading member 5 works undershot, i.e.
  • the material obtained is conveyed to the center between the extraction and loading element 5 and the guide element 6 arranged behind it and passed through an opening 11 provided here to the conveyor belt 9 provided on the device.
  • the combined extraction and loading element 5 and the guide element 6 are rotatably mounted about a horizontal axis 12 in the area of the suspension 8 formed from a fork.
  • the suspension itself and thus also the extraction and loading element 5 can be pivoted in the transverse direction on the device side about an axis pin 13 which also runs horizontally but is arranged in a different plane than the horizontal axis 12.
  • the horizontal axis 12 is arranged between the end regions 14 of the fork legs.
  • Hydraulic cylinders 15, which are articulated on the fork 8 on the one hand and on the other hand on a vertical extension 16 of the guide element 6, serve to rotate the extraction and loading element 5 about the horizontal axis 12. During the actuation of the hydraulic cylinders 15, they pivot about the fork-side pivot point 17 while simultaneously lifting the extraction and loading element 5.
  • the deflection roller 18 of the conveyor belt 9 is also placed around the horizontal axis 12. Falling of the material obtained on the ground 20 is prevented by other organs, not shown.
  • the pivoting movement of the fork 8 about the axle journal 13, which preferably runs along the device center line, is generated by a lifting cylinder 21 extending between the superstructure 4 and the fork 8 outside the device center line.
  • FIG. 2 shows a partial section of the fork 8. It consists of a leg 24 arranged transversely in front of the device and a respective side leg 25.
  • the fork 8 can be pivoted on the device side about the already mentioned axle journal 13 (only indicated) and is supported in this area by sliding bearings 26.
  • plain bearings 27 are provided for receiving the horizontal axis.
  • a sliding element 31, 32 is provided in the outer regions 28, 29 of both the fork leg 24 and the corresponding end face 30 of the device 1.
