Definitions

  • the invention relates to a carrier vehicle, preferably a tracked vehicle, and a paddle wheel Existing extraction device with cutting edges for the blasting-free extraction of mining materials, such as Overburden, coal and.
  • the carrier vehicle with a working hydraulics is provided, the at least one Has hydraulic pump and several hydraulic cylinders, wherein the paddle wheel by several arranged side by side Cutting wheels can be formed, and wherein Provide the extraction device with a restraint is the too large clods detached from the paddle wheel - Lumps of soil or stone - prevents or holds back.
  • a combined shredding and clearing device (FR 2 607 350 A1), are used to determine the Cutting depth of the knife on one side of the Device a bottom roller and on the other side a leveling plate is provided.
  • the altitude the bottom roller which can be swiveled around an axis, in steps to be changed.
  • one with several Drilled backdrop provided. Through one of the Drilling becomes through the swivel arm of the bottom roller penetrating bolt inserted, the altitude the bottom roller by choosing the hole in the backdrop is determined in which you insert the bolt.
  • the floor roller is not designed to do that - and not suitable for this either - detached from the knives Retain soil material.
  • the invention has for its object a mining device to create where the restraint, the too large one picked up by the paddle wheel Holds back clods, is so formed that formation larger plaice is not possible or at least that damage to the extraction device from larger ones Plaice is prevented.
  • the body is expediently of great weight formed by at least one roller.
  • a roller can the particular soil conditions particularly well to adjust.
  • the surface of the roller can also be profiled his.
  • they are the body of large weight forming rollers so displaceable stored that they can make a bank.
  • the adaptability of the rollers to the Surface of the soil to be mined increased significantly.
  • Compliance with the removal of the body from large Weight above the soil to be dismantled can be with usual technical means are effected, for example by means of a placed under the body of great weight Landing gear, whose wheels against the body of great weight in the vertical direction accordingly survive.
  • To ensure compliance with the removal of the body of great weight above the soil to be excavated is particularly easy to ensure is in Development of the invention on the boom corresponding sensor arranged.
  • At least one cylinder and / or at least one Spindle provided for adjusting the distance between the body of great weight and the blades of the paddle wheel.
  • Such adjustment devices are particularly easy.
  • the swinging boom As The distance between becomes part of a four-bar frame the body of great weight and the cutting of the Paddle wheel almost constant at every cutting height held.
  • the method according to the invention enables the body of great weight for the purpose of moving and after the change of location the body of great weight again.
  • the inventive method is trouble-free Control of the restraint guaranteed.
  • the hydraulic cylinder is under pressure via its pressure relief valve. Thereby becomes an overload of the paddle wheel drive and entire steel structure of the extraction device prevented.
  • Opening the hydraulic circuit turns a rapid evasion of the body from great weight allows the cutting area of the paddle wheel, so that blocking the paddle wheel before reaching the maximum drive torque is prevented. This will achieved that even when hitting the paddle wheel an indestructible chunk of rock, the extraction device is not damaged.
  • the extraction device 1 shown in FIGS. 1 and 2 consists of a carrier vehicle 2 and attached to it Paddle wheels 3, which are provided with cutting edges 4.
  • the extraction device 1 is with a restraint device 5 provided that received by the paddle wheels 3 Boulders or rocks at least partially holds back.
  • the restraint device 5 has at least one - in the exemplary embodiment as rollers trained - body 6 of great weight on the directly on the surface of the soil to be mined rests and in front of the cutting edges 4 of the paddle wheels 3 - Based on the direction of movement B of the extraction device 1 - is arranged.
  • the one formed by rolling Body 6 is on a swinging boom 7 on the Carrier vehicle 2 attached, the body 6 on one End of the boom 7 is attached, the other end is articulated on the carrier vehicle 2.
  • On the boom 7 is also one of the ends of two hydraulic cylinders 8 articulated with the working hydraulics of the carrier vehicle 2 are connected and their respective other end is attached to the carrier vehicle 2.
  • the restraint device 5 has at least one body 6 ' of great weight on the short distance E is arranged above the ground to be dismantled. Also at In this embodiment, the body 6 'is large Weight at adjustable distance A in front of the cutting edges 4 of the paddle wheel 3 - based on the direction of movement B of the extraction device 1 - arranged.
  • the body 6 ' is of great weight a swinging boom 7 on the carrier vehicle 2 attached
  • the body 6 'of great weight on the one end of the boom 7 is attached during the Boom 7 with its other end on the carrier vehicle 2 is articulated, and is on the swinging boom 7th one end each articulated by two hydraulic cylinders 8, with the working hydraulics of the carrier vehicle 2 are connected and their respective other ends the carrier vehicle 2 is attached.
  • the distance E of the body 6 'of great weight the soil to be removed is a corresponding one on the boom 7 Sensor 16 arranged.
  • Figs. 3 and 4 are the Body 6 of heavy weight rollers so displaceable stored that they make a bank can.
  • each individual roller can move through an angle W be pivoted.
  • FIG. 5 are shown in the performance example for setting the distance A between the body 6 of great weight and the cutting edges 4 of the Paddle wheels 3 cylinder 9 provided.
  • the body 6 formed by rolling is large Weight attached. The movement that the body 6 under the influence of the rocker arm 10 can run through an arrow 11 indicated.
  • a extraction device in which the swinging boom 7 part of a four-bar frame is.
  • the hinge points P1 and P3 establish a connection with the carrier vehicle 2, while the hinge points P2 and P4 connect to produce a lever 14.
  • At the bottom of the Lever 14 is attached to the body 6 of great weight. The movement that the body 6 in this case - by means of the four-bar frame - can indicated by an arrow 15.
  • Fig. 8 From the circuit diagram shown in Fig. 8 is the Control of the extraction device can be seen from which the For the sake of clarity, only the two hydraulic cylinders 8 are shown for better understanding the controller are designated 8L and 8R.
  • Each Hydraulic cylinder 8L is a control unit SL and each Hydraulic cylinder 8R assigned a control unit SR. Since the two control units SL and SR each other the explanation below applies only on the control unit SL.
  • the controls of Control unit SR are also not with reference numerals Mistake.
  • the reference symbol is merely an example entered for the pressure relief valve S13R. In the the drawing shown with dashed lines Lines represent the lines for the return of the Hydraulic oil or the leak oil.
  • the control unit SL has a line L1, which from a hydraulic oil tank S1 to one with the one below the piston of the hydraulic cylinder 8 located cylinder space connected line L2 leads. Above the hydraulic oil tank S1 is in the line L1 a hydraulic pump that can be driven by an electric motor S2 S3 provided. There is a line L2 Directional control valve S4, which has a spring-loaded check valve S5 is connected downstream. In one from line L1 to Hydraulic oil reservoir S1 is return line L3 a pressure relief valve S6 is provided.
  • Another line L4 leads from the hydraulic oil tank S1 via a line L5 in the above the Piston of the hydraulic cylinder 8 located cylinder space.
  • Directional valve S7 is provided in line L4, which is followed by a throttle check valve S8.
  • a pressure switch S9 is connected to line L4.
  • a connecting line runs between lines L2 and L4 L6 with a directional valve S10 and one One-way flow control valve S11 and another connecting line L7, in which a pressure relief valve S12 is provided.
  • a pressure relief valve S13 for example a so-called cartridge valve is provided.
