Definitions

  • the present invention relates in particular to one in the WO 2020/007846 A1 undisclosed mobile rock processing device with a chassis which allows the rock processing device to change the installation location in a self-propelled manner and/or to move in a self-propelled manner between a location for a rock processing operation and a means of transport for transporting the rock processing device.
  • the chassis Due to the generally high weight of the mobile, especially self-propelled, rock processing device, the chassis is usually a crawler chassis, although a wheeled chassis as an alternative or in addition to a crawler chassis should not be ruled out.
  • a rock processing device with both a screening device and a crushing device is from the US 4,281,800 known.
  • This previously known rock processing device is part of a rock processing plant with a rock mill downstream of the rock processing device in the material flow.
  • the rock processing device is continuously loaded with material to be processed from a quarry by a conveyor belt.
  • a rock processing device which, via a light system, such as a type of traffic light system, indicates to vehicles that load the rock processing device discontinuously that they are currently ready for new rock to be supplied.
  • a light system such as a type of traffic light system
  • the object of the present invention is therefore to improve the rock processing device on the output side for dispensing processed material for the most advantageous technical and economical operation possible.
  • control device is designed to determine, in an operation with discontinuous mining of the at least one stockpile, mining time information based on the at least one detection signal, which determines an execution time of a future mining of the Stockpile represented by material removal from the stockpile, the output device being designed to output the determined degradation time information.
  • the detection signal of the stockpile sensor can represent a state of the stockpile, in particular a state of the size and/or shape of the stockpile.
  • the size of the heap can be represented by its height above the ground supporting it or by parameter values from which this height can be deduced.
  • the size of the heap can also be determined by detecting the state of the shape of the heap, for example in the case of a cone-shaped heap by knowing the diameter of its base resting on the base that supports it and the inclination of its lateral surface relative to the base or the cone angle.
  • the at least one heap sensor can thus detect at least one shape dimension of the heap as the at least one heap parameter.
  • Possible design dimensions are the previously mentioned parameters: heap height, diameter or generally a characteristic dimension of the heap base and/or area of the heap Heap base, angle of inclination of the heap surface extending from the heap base to a heap head that is distant from the heap base in the height direction.
  • the control device is then designed to determine a height of a heap head based on the at least one recorded shape dimension.
  • the rock processing device preferably comprises a time measuring device, which is connected to the control device in terms of signal transmission, optionally with the interposition of a data memory.
  • the or a time measuring device can be integrated into the at least one sensor and/or into the input device and/or into the control device.
  • the control device can assign an event time to detection events of the at least one stockpile sensor and/or detection events of at least one operating sensor for detecting at least one operating parameter of the rock processing device and/or input events of at least one input device. From the time interval of at least two event times for a similar event, such as the detection of one and the same stockpile parameter or one and the same operating parameter, the control device can determine a rate of change assigned to the respective events.
  • the control device can thus determine a rate of change in the heap size and/or the heap shape from two detections of the heap height or generally of a state of the heap size and/or the heap shape and the known time interval between these detection events. This is an example of determining a temporal change in the height of the heap head of the heap as a growth parameter of the heap.
  • the control device can, for example by extrapolation, determine a next execution time for material degradation, if necessary taking into account a safety margin, which is intended to ensure that the heap does not reach a predetermined location.
  • the predetermined location can be a discharge area of the discharge conveyor device building the respective heap in order to prevent the heap from reaching the discharge conveyor device grows and collides with it and/or blocks it.
  • the predetermined location can additionally or alternatively be the spatial area of a neighboring heap in order to prevent mixing of its material with the material of the currently dumped heap.
  • a degree of filling of the discharge conveyor device forming the respective stockpile can be detected as a relevant operating parameter of the rock processing device by at least one operating sensor.
  • the delivery capacity of the discharge conveyor has a direct influence on the growth of the stockpile.
  • the at least one determined heap parameter can be checked for plausibility or even corrected by the control device. The same applies to the detection of a conveying speed of the discharge conveyor, which builds up the respective stockpile through its conveying operation.
  • the product of the filling level and the conveying speed of a conveyor device provides a measure of the volume of material conveyed by the conveyor device or for the conveying capacity of the conveyor device.
  • the conveyor device and the discharge conveyor device can each be a belt conveyor device or a trough conveyor device, the latter preferably conveying as a vibration conveyor according to the micro-throw principle.
  • a vibration conveyor preferably in the form of a trough conveyor, is particularly preferred as a conveying device for conveying between material buffers and a crushing device.
  • the rock processing device can also have a plurality of conveying devices and will generally have such a plurality, for example because the same conveying device cannot convey as a feed conveying device from the material buffer away to a work unit and as a discharge conveying device from a work unit away from the rock processing device out to a stockpile constructed thereby .
  • these can use different conveying principles, such as the micro-throwing principle already described above for vibration conveyors and/or as a Belt conveyor, whereby the belt conveyor is generally used as a discharge conveyor due to the smaller grain size that occurs in the discharge and a usually more homogeneous grain size distribution.
  • a conveying speed of a conveying device can be determined in different ways.
  • the conveying speed can be determined independently of the type of conveying device by detecting a movement in the conveying direction of a material lying on the conveying device, for example using a light barrier, ultrasound, optical detection and image processing and the like.
  • a conveying speed of a belt conveyor can be detected by detecting the speed of a roller cooperating with the conveyor belt, be it a support roller or a drive roller, or by detecting directly the path speed of the conveyor belt.
  • the vibration amplitude and the vibration frequency can be a measure of the speed of material resting on a vibration conveyor, so that a detection of the vibration amplitude and the vibration frequency is a detection of variables representing the conveying speed.
  • conveying capacity can be derived from the drive power of a motor driving them, so that the conveying capacity can be derived indirectly from the detection of an engine torque and an engine speed.
  • the delivered motor torque can be determined from the drawn motor current.
  • the delivered torque is proportional to the product of the pressure drop across the hydraulic motor and its displacement.
  • a torque map can be determined for each motor depending on its manipulated variables and stored in a data memory or in the data memory already mentioned above. The engine torque can then be determined from the recorded manipulated variables by retrieving the torque map from the control device.
  • the control device can determine a future requirement of the rock processing device for mining or removal of material onto the at least one stockpile based on the at least one detection signal determined processed material issued and thus forecast as dismantling time information.
  • degradation and “removal” are used synonymously in the present application.
  • third parties such as a machine operator of a mining device, can take note of the mining time information and consequently plan their material mining in advance at the at least one heap formed by the rock processing device.
  • the determined and output dismantling time information can be processed automatically by a data processing device, such as a control device, at least one dismantling device, and its dismantling operation can be set up and executed taking the dismantling time information into account, so that material is actually dismantled at the execution time represented by the dismantling time information on which at least one dump can be carried out.
  • a data processing device such as a control device, at least one dismantling device, and its dismantling operation can be set up and executed taking the dismantling time information into account, so that material is actually dismantled at the execution time represented by the dismantling time information on which at least one dump can be carried out.
  • the rock processing device can have more than one discharge conveyor device, each of which creates a stockpile during the intended operation of the rock processing device.
  • a discharge conveyor device can also be arranged to be movable relative to a machine frame of the rock processing device, so that one and the same discharge conveyor device can successively build up more than one stockpile. This also applies to a discharge conveyor device from a plurality of discharge conveyor devices of the rock processing device.
  • the execution time can be an execution time and/or an execution time range.
  • the execution time can indicate the earliest possible future point in time at which material can or should be mined or removed from the at least one heap.
  • the execution time can additionally or alternatively indicate a future period of time over which material can or should be mined or removed from the at least one heap.
  • the dismantling time information can be relative dismantling time information based on a reference time, such as the current actual time.
  • the dismantling time information can be output in the form of a waiting period until the next material dismantling.
  • the dismantling time information can be absolute dismantling time information which represents an execution time or a start of an execution period as a time in the relevant time zone. If necessary, an end of the execution period can again be as absolute dismantling time information or as relative dismantling time information related to a reference point in time, preferably to the beginning of the execution period. As a rule, however, it will be sufficient to specify the point in time as the execution time from which material removal can take place in the future.
  • the execution time represented by the dismantling time information is in the future. This is not just about a theoretical future based on signal transmission times in the micro- or nanosecond range, but about a future that is at least a single-digit second range away from the time at which the degradation time information is issued.
  • the execution time will often be in the two or even three or four digit seconds range from the time when the dismantling time information is issued in the future.
  • the rock processing device is preferably designed to determine an individual execution time as mining time information for at least two, particularly preferably for more than two, successive future material removals in the operation with discontinuous mining of the at least one stockpile and to output it using the output device.
  • the execution times of a series of successive material removals can be individually for the operating situation of the heap that has been mined and further built up by its assigned discharge conveyor, which is evolving as a result of the previous material removal, and/or by a sensor-detected one Operating parameters of the rock processing device are determined appropriately and output as mining time information.
  • the rock processing device can have only one or more screening devices as the at least one working unit.
  • the rock processing device is then purely a screening system.
  • the rock processing device can as the at least one work unit have only one or more breaking devices.
  • the rock processing device is then purely a crushing plant.
  • the rock processing device includes both at least one screening device and at least one crushing device.
  • the screening device can be a pre-screen upstream of the crushing device in the material flow, optionally with several screen decks, and/or can be a secondary screen downstream of the crushing device in the material flow in order to sort the result delivered by the crushing device according to grain sizes.
  • the secondary screen can also include at least one screen deck or several screen decks.
  • the crushing device may be any known crushing device, such as an impact crusher or a jaw crusher or a cone crusher or a roll crusher. Then, if the rock processing plant has more than one crushing device, these crushing devices may be similar crushing devices or different types of crushing devices. Each individual crushing device can be one of the above crusher types of impact crusher, jaw crusher, cone crusher and roller crusher.
  • control device can be designed to retrieve a lower altitude threshold of the heap from a data memory and, based on the growth parameter, to determine dismantling time information for the earliest future dismantling of the heap.
  • the lower altitude threshold or a further lower altitude threshold can also be used by the control device to determine a maximum amount of material that can be removed from the stockpile in order to ensure that a minimum size of the stockpile remains after material has been mined.
  • control device can be designed to retrieve an upper altitude threshold of the stockpile from a data memory and, based on the growth parameter, to determine dismantling time information for a latest future dismantling of the stockpile.
  • the data storage is preferably the data storage already mentioned above.
  • the rock processing device preferably comprises a data memory, which is connected to the control device and preferably also to the at least one stockpile sensor in terms of signal transmission.
  • the control device determines the mining time information exclusively from detection signals from the at least one stockpile sensor, possibly taking into account detection signals from at least one operating sensor for determining at least one operating parameter of the rock processing device, it should not be ruled out that the control device is involved in the determination
  • the dismantling time information also takes into account information input by a machine operator or another person.
  • the rock processing device comprises an input device for inputting information, the input device for transmitting information being connected to the control device in terms of signal transmission, the control device being designed to operate in the operation with discontinuous heap mining to determine the degradation time information based on the at least one detection signal and information entered into the input device.
  • the input device can be any input device, such as a keyboard, a touch screen, and the like.
  • the input device can also be connected to the control device for signal transmission via a cable route or a radio link, so that it does not necessarily have to be physically present on the rock processing device.
  • a signal transmission connection between the input device or the at least one heap sensor and/or the at least one operating sensor with the control device is also a connection with the intermediate arrangement of the data memory, in which information entered into the input device and/or from the at least one heap sensor for detecting the at least one heap parameter or/and information output by the at least one operating sensor as Data is stored and retrieved as stored data by the control device.
  • the input device and/or the at least one stockpile sensor and/or the at least one operating sensor can be connected directly to the data memory in terms of signal transmission, so that the input device can transmit information entered into it just as directly into the data memory for storage as the at least one stockpile sensor and/or the at least one operating sensor provides results of the respective detection operation of the sensor.
  • Data that does not change over the operating life of the rock processing device or can only be changed with great effort can be permanently stored in the data memory and, for example, by the manufacturer of the rock processing device during the production of the same or . must be deposited before delivery.
  • the machine configuration changes for example during maintenance or repairs
  • the company carrying out the maintenance or repairs can make corresponding changes to the contents of the data memory.
  • the data memory can be physically connected to the control device via a signal line and/or incorporeally in terms of signal transmission, for example via a radio link or via a transmission of optical signals.
  • the data storage can therefore be provided separately and at a distance from the rest of the rock processing device.
  • the “remaining rock processing device” is represented by its machine body.
  • the machine body includes the machine frame and all components of the rock processing device connected thereto, even if these are arranged to be movable relative to the machine frame.
  • the stockpile sensor can be arranged in various ways in relation to the rest of the rock processing device.
  • the at least one heap sensor can be arranged as a device-supported heap sensor on the rock processing device.
  • the discharge conveyor device which accumulates the heap detected by the heap sensor, is spatially particularly close to the heap to be detected by sensors, the discharge conveyor device is a possible preferred location for arranging the heap sensor.
  • the discharge conveyor device is often a belt conveyor device which throws off processed material, so that, taking into account a lateral distance due to the trajectory of the thrown material in the form of a throwing parabola, a heap grows upwards over time under the discharge longitudinal end of the discharge conveyor device.
  • a longitudinal end region of the discharge conveyor device containing the discharge longitudinal end is a preferred location for the stockpile sensor.
  • the longitudinal end region preferably contains the last 20%, particularly preferably the last 10%, of the conveying length of the discharge conveyor including the discharge longitudinal end.
  • the at least one heap sensor can be fixed as a stationary, ground-based heap sensor spatially distant from the rock processing device, but connected to it in terms of signal transmission, in the surroundings of the rock processing device.
  • the at least one stockpile sensor can be set up or anchored on the ground with its own frame or scaffolding, so that it can detect the stockpile it is monitoring particularly well, but remains largely unaffected by a spatial distance from dirt or flying bulk material.
  • the at least one stockpile sensor can be provided as a mobile stockpile sensor that is movable relative to the rock processing device, but connected to it in terms of signal transmission.
  • the stockpile sensor can be arranged on another vehicle on the construction site on which the rock processing device is used.
  • the stockpile sensor can be arranged on a flying drone, which flies over and/or around the stockpile to be detected by the at least one stockpile sensor, in particular over and/or flies around it according to a predetermined pattern, so that information about the stockpile from the stockpile sensor at different times, however can preferably be recorded from the same recording locations, which increases the comparability of information about the stockpile recorded at different times.
  • the control device can do this
  • the rock processing device can preferably be designed to allow a flying drone carrying at least one stockpile sensor to fly remotely along a predetermined trajectory in accordance with a predetermined program.
  • the predetermined trajectory can be previously determined using a teach-in process and stored in the data memory.
  • at least one stockpile sensor can be located on a ground-based remote-controlled vehicle, although this is less preferred due to the higher risk of damage due to the harsh operating conditions on a typical construction site.
  • construction site generally includes all sites where material to be processed by the rock processing device is produced or provided, such as quarries, gravel pits, recycling centers, building demolition sites and the like.
  • the term “mineral material” therefore includes both natural and processed mineral material. The latter includes building materials as well as recycled oversize.
  • the at least one stockpile sensor can detect the at least one stockpile parameter based on different physical operating principles.
  • the at least one stockpile sensor can acoustically detect the at least one stockpile parameter, in particular using ultrasound.
  • a distance between the heap, in particular the heap head, and the heap sensor can be determined from the transit time of ultrasound reflected from the heap, in particular from the heap head. From the known arrangement position of the heap sensor relative to the machine frame of the rock processing device and the known geometry of the machine frame, the position of the heap sensor relative to the ground surrounding the rock processing device and thus information about the height of the heap head can be obtained from the detection signal.
  • the heap sensor can detect the heap and in particular the heap head using electromagnetic radiation.
  • transit time measurements of reflected electromagnetic rays can in turn be used analogously to the ultrasound-based detection described above to determine a distance of the irradiated heap area to the heap sensor and from this information, taking into account the known arrangement position of the heap sensor, a known one Radiation direction and known machine dimensions enable the determination of information about the altitude of the irradiated heap area.
  • Detecting the at least one stockpile parameter with electromagnetic radiation also includes the use of passive electromagnetic radiation, for example light that is reflected by the stockpile.
  • passive electromagnetic radiation for example light that is reflected by the stockpile.
  • height information and/or shape information of the stockpile can be detected tactilely by bringing a tactile element, known in its spatial arrangement relative to the stockpile sensor, into contact with a surface of the stockpile, starting from a known location of the stockpile sensor. If the sensing element is applied multiple times, points on the heap surface can be determined and extrapolated to a heap shape.
  • the output device can be designed to output information about the type and/or the composition and/or the location of the stockpile material in addition to the mining time information.
  • Information about the type of stockpile material may have been previously entered via the input device or may have been transmitted to the rock processing device from another device on the site. Furthermore, information about the type of stockpile material may have been determined at the rock processing device itself. Information about the type of stockpile material includes information about the average grain size, the grain size distribution, the grain shape, the moisture content, the abrasiveness, the breaking behavior of the material or even the color of the material. The same applies to the determination and provision of information about the composition of the material.
  • This can, for example be determined at the construction site by a separate device or by appropriate sensors on the rock processing device by irradiation with high-energy electromagnetic rays, such as X-rays, from the irradiation response of the irradiated material based on characteristics stored in the data memory.
  • high-energy electromagnetic rays such as X-rays
  • the location of the stockpile material can be determined and output from the location of the rock processing device known, for example by the GPS receiver of the rock processing device, and the location of the stockpile known by the at least one stockpile sensor relative to the rock processing device.
  • the output device can output the location of the heap to be mined in GPS coordinates and/or in coordinates relative to a reference point of the rock processing device and/or the construction site. In this way, a mining device can not only receive information about when it should break down material and, if necessary, how much, but also where this should take place. When several heaps are piled up on a construction site, this makes the orientation of the mining device and targeted mining much easier.
  • the output device can be designed to output information in a type of non-directional output, independent of the receiver, into a spatial area that at least partially surrounds the rock processing device and/or is adjacent to the rock processing device. This preferably means that no receiving device is necessary to reproduce the dismantling time information output by the output device in a version that can be understood by humans or by electronic data processing devices.
  • the output device can thus output the dismantling time information in a visually perceptible manner, for example by displaying a time that shows the calculated earliest possible dismantling time for the next material dismantling. Instead of an absolute time, a remaining waiting time until the next dismantling time can be displayed. This can be done digitally or analogue, graphically or numerically.
  • the waiting time until the next dismantling time can be represented numerically by a digital clock with a time unit countdown, for example in seconds or in seconds and minutes.
  • the waiting time can also be represented graphically and numerically by an analog clock or by an analog pointer instrument, for example again with a time unit countdown by means of a corresponding continuous or stepwise pointer movement.
