Description

TECHNICAL FIELD

[0001] The invention relates to a rock processing plant for comminuting and / or sorting particulate mineral material according to size, wherein the rock processing plant comprises as plant components:

[0002] - a material loading plant with a material buffer for loading raw material to be processed,

[0003] - at least one working unit, which working unit consists of

[0004] + at least one crushing plant and

[0005] + at least one screening plant,

[0006] - at least one conveying plant for conveying material between two plant components,

[0007] - at least one discharge conveying plant for conveying processed material from the rock processing plant to a discontinuously exploitable stockpile,

[0008] - a control plant for controlling the plant components of the rock processing plant,

[0009] - at least one stockpile sensor for detecting at least one stockpile parameter, which stockpile parameter represents a state or / and a change in spatial dimensions or / and a configuration of the stockpile over time, wherein the stockpile sensor is connected to the control plant in terms of signal transmission for transmitting a detection signal representing the at least one detected stockpile parameter,

[0010] - at least one output plant for outputting information, wherein the output plant is connected to the control plant in terms of signal transmission for transmitting information. BACKGROUND

[0011] From WO 2020 / 007846 A1 a method and a plant for managing bulk material of a mine pit are known in the prior art. This document focuses mainly on establishing a conveying device for a stockpile to be exploited. However, it is mandatory to install upstream of the conveying device a plant which comminutes the material in the mine pit into particulate bulk material, which is finally conveyed by the conveying device to the stockpile. The method and the plant known from WO 2020 / 007846 A1 are mainly used to record locally, when establishing the stockpile, areas of the bulk material deposited which have the same material parameters within one area, however different between the areas, like for example the mineral composition, so that a targeted excavation of the mineral composition can be achieved when exploiting the stockpile.

[0012] The invention relates in particular to mobile rock processing plants with a traveling mechanism which changes the installation site of the rock processing plant in an automated manner or / and travels between an installation site for a rock processing operation and a transport vehicle for transporting the rock processing plant in an automated manner. Due to the usually high weight of the mobile, in particular automated, rock processing plant, the traveling mechanism is usually a caterpillar traveling mechanism, although a wheel traveling mechanism should not be ruled out alternatively or in addition to the caterpillar traveling mechanism.

[0013] A rock processing plant with a screening plant and a crushing plant is known from US 4,281,800. The previously known rock processing plant is part of a rock processing facility with a stone mill downstream of the rock processing plant in the material flow. The rock processing plant is continuously loaded with material to be processed from a quarry by a conveyor belt.

[0014] A rock processing plant is known from US 4,909,449 which displays via a lighting facility, for example a traffic light facility, to a vehicle which discontinuously loads the rock processing plant, that it is currently ready for filling with newly conveyed rock.

[0015] It is required for an optimal technical and economic operation that the stockpile built up by the discharge conveyor plant is mined again in time before its very strong growth such that it grows at the expense of or affects the operation of the discharge conveyor plant. It is furthermore helpful for an optimal economic operation to mine the stockpile according to external circumstances, however strongly, in order not to endanger its stability. Especially in strong winds, material dumped onto a stockpile which is mined too strongly can be undesirably blown away due to the long fall duration, whereby material processed by the rock processing plant is lost. SUMMARY

[0016] It is therefore an object of the invention to improve a rock processing plant on the output side for outputting processed material for an as favorable as possible technical and economic operation.

[0017] The invention achieves these objects for the initially mentioned type of rock processing plant by the control device being configured to determine, in the operation with discontinuous mining of at least one stockpile, based on at least one detection signal, mining time information which represents the implementation time of future mining of the stockpile by extracting material from the stockpile, and the output device being configured to output the determined mining time information.

[0018] The detection signal of the pile sensor can represent a state of the pile, in particular a state of the size or / and the configuration of the pile. The size of the pile can be represented by its height above the ground on which it is carried or by a parameter value from which the height can be inferred. Thus, by detecting the state of the configuration of the pile, its size can likewise be inferred, for example in the case of a conical pile, by knowing the diameter of its base on the ground on which the pile is carried and the inclination or cone angle of its side surface relative to the ground.

[0019] Thus, the at least one pile sensor can detect a configuration size of the pile as at least one pile parameter. Possible configuration sizes are the parameters mentioned earlier: the pile height, the diameter of the pile base or in general a characteristic size or / and the area of the pile base, the inclination angle of the pile side surface extending from the pile base towards the pile top away from the pile base in the height direction. The control device then constitutes a means for determining the height position of the pile top on the basis of at least one detected configuration size.

[0020] The rock processing plant preferably comprises a time measuring device which is connected to the control device in terms of signal transmission, if necessary with an intermediate data memory. The time measuring device or the time measuring device can be integrated into at least one sensor or / and input device or / and control device. By means of the signal of the time measuring device, the control device can associate a detection event of at least one pile sensor or / and a detection time of at least one operating sensor for detecting at least one operating parameter of the rock processing plant or / and an input event of at least one input device with an event time. From the time interval of at least two event times for the same type of event, for example the detection of the same pile parameter or the same operating parameter, the control device can determine a change rate associated with the respective event. Thus, the control device can determine the change rate of a pile variable or / and a state of the pile configuration from two detections of the pile height or in general a pile variable or / and the state of the pile configuration and the known time interval between the detection events. This is an example for determining the change of the height position of the pile top of the pile over time as a growth parameter of the pile.

[0021] From the determined growth parameter and by detecting a known pile size or / and a state of the pile configuration, the control device can determine the next implementation time of the material extraction, if necessary taking into account a safety margin, which should ensure that the pile does not reach a predetermined location, for example by extrapolation. The predetermined location can be the dumping area of the unloading conveyor device on which the respective pile is built in order to prevent the pile from growing to the unloading conveyor device and colliding with or / and blocking the unloading conveyor device. The predetermined location can additionally or alternatively be a spatial region of an adjacent pile in order to prevent the material of the adjacent pile from mixing with the material of the currently dumped pile.

[0022] In addition to the state of the size or / and configuration of the pile, the filling level of the discharge conveyor device establishing the respective pile can be detected by the at least one operating sensor as an important operating parameter of the rock processing plant. The conveying power of the discharge conveyor device then has a direct influence on the pile growth. Thus, by detecting the filling level of the discharge conveyor device dumping the respective pile, the at least one derived pile parameter can be checked for plausibility or even corrected by the control device. The respective case applies to the detection of the conveying speed of the discharge conveyor device by which the respective pile is established by its conveying operation.

[0023] The product of the conveying speed and the filling level of the conveyor device gives a quantity representing the volume of material conveyed by the conveyor device or the conveying power of the conveyor device.

[0024] The conveyor device and the discharge conveyor device can each be a belt conveyor device or a trough conveyor device, wherein the latter is preferably conveyed as a vibrating conveyor according to the micro-throw principle. Just as the conveyor device for conveying between the material buffer and the crushing device is preferably a vibrating conveyor, preferably in the configuration of a trough conveyor device. The rock processing plant can also have a plurality of conveyor devices and usually as many, for example because not the same conveyor device can be used as a filling conveyor device away from the material buffer towards the working unit and as a discharge conveyor device away from the working unit from the rock processing plant onto the pile established thereby. In the case of a plurality of conveyor devices, the conveyor devices can utilize different conveying principles, like the micro-throw principle in vibrating conveyors already described above or / and like belt conveyor devices, wherein belt conveyor devices are often applied as discharge conveyor devices due to the smaller grain size and usually more uniform grain size distribution generated in the discharge.

[0025] The conveying speed of the conveying device can be determined in different ways and methods. The conveying speed can be determined independently of the type of the conveying device by detecting the movement in the conveying direction of the material located on the conveying device, for example by means of a grating, by means of ultrasound, by optical detection and image processing, etc. The conveying speed of a belt conveyor can be detected by detecting the rotational speed of a roller cooperating with the conveyor belt, such as a support roller or a drive roller, or by directly detecting the belt speed of the conveyor belt. In a vibrating conveyor, the vibration amplitude and the vibration frequency are values which represent the speed of the material lying on the vibrating conveyor, so that detecting the vibration amplitude and the vibration frequency is detecting a variable which represents the conveying speed. It also applies to all conveying devices that the conveying power thereof can be derived from the drive power of the motor driving the conveying device, so that the conveying power can be derived indirectly from the detection of the motor torque and the motor rotational speed. For some construction types of electric motors, the output motor torque can be determined from the absorbed motor current. For hydraulic motors, it applies that the output torque is proportional to the product of the pressure drop over the hydraulic motor and its displacement. Otherwise, for each motor, a family of torque characteristic curves can be determined in relation to its adjustment variable and stored in a data memory or in the data memory already mentioned above. The motor torque can then be determined from the detected adjustment variable by calling up the family of torque characteristic curves by the control device.

[0026] Since the detection signals, as described at the outset, represent at least one sensorically detected pile parameter, the control device can determine, on the basis of the at least one detection signal, the future demand of the rock processing device for the extraction or excavation of the processed material output to the at least one pile and, in turn, as extraction time information. The terms "extraction" and "excavation" are used synonymously in this application. By outputting the determined extraction time information, a third party, such as for example a mechanical operator of the extraction device, can be informed of the extraction time information and, in turn, plan the extraction of the at least one pile of material formed by the rock processing device in advance. Alternatively, the determined and output extraction time information can be processed automatically by a data processing device of the at least one extraction device, such as for example a control device, and its extraction operation is set up and implemented in such a way that, at the implementation time represented by the extraction time information, the extraction of the material of the at least one pile can actually be carried out.

[0027] In principle, the rock processing device can have more than one discharge conveyor device, wherein each discharge conveyor device builds up a pile during the regular operation of the rock processing device. The discharge conveyor device can also be arranged movably with respect to the machine frame of the rock processing device, so that the same discharge conveyor device can gradually build up more than one pile. This also applies to one of the plurality of discharge conveyor devices of the rock processing device.

[0028] The implementation time can be an implementation point in time or / and an implementation time range. The implementation time can specify the earliest possible future point in time at which material at the at least one pile can or should be mined or excavated. The implementation time can additionally or alternatively specify a future time period across which material at the at least one pile can or should be mined or excavated.

[0029] The mining time information can be relative mining time information in relation to a reference time, for example the actual current time. The mining time information can be output, for example, in the form of a waiting duration until the next mining of material. Alternatively, the mining time information can be absolute mining time information which specifies the implementation point in time or the start of the implementation time period as a time in the respectively relevant time zone. If desired, the end of the implementation time period can again be specified as absolute mining time information or as relative mining time information in relation to a reference point in time, preferably in relation to the start of the implementation time period. However, it is usually sufficient to specify the point in time from which material mining can be carried out in the future as the implementation point in time.

[0030] At the point in time at which the mining time information is output by the output device, the implementation time represented by the mining time information is in the future. Here, this not only takes into account the theoretical future based on the signal transmission duration in the range of microseconds or nanoseconds, but also a future which is at least in the range of seconds from the point in time at which the mining time information is output. Usually, the implementation time is in the future in the range of two or even three or four digits of seconds from the point in time at which the mining time information is output.

[0031] Preferably, the rock processing device is configured to, in the operation with discontinuous mining of the at least one pile, determine individual implementation times as mining time information for at least two, in particular preferably more than two, future material excavations following one another and to output these individually by means of the output device. Thus, a series of implementation times of material excavations following one another can be individually determined in relation to at least one pile parameter represented by the at least one detection signal and in relation to the operating situation of the rock processing device and the pile established by the associated discharge conveyor device which develops from the preceding material excavation and / or in relation to operating parameters detected in a sensor-based manner and output as mining time information.

[0032] The rock processing plant as at least one working unit can have only one or more screening devices. The rock processing plant is then a pure screening plant. Likewise, the rock processing plant as at least one working unit can have only one or more crushing devices. The rock processing plant is then a pure crushing plant. In a preferred configuration, the rock processing plant comprises not only at least one screening device but also at least one crushing device. The screening device can be a pre-screen upstream of the crushing device in the material flow, if necessary with a plurality of screen decks, or / and can be a post-screen downstream of the crushing device in the material flow in order to sort the result provided by the crushing device according to the grain size. The post-screen can also comprise at least one screen deck or a plurality of screen decks.

[0033] The crushing device can be any known crushing device, for example a vibrating crusher or a jaw crusher or a cone crusher or a roller crusher. If the rock processing plant has more than one crushing device, then these crushing devices can be crushing devices of the same type or crushing devices of different types. Each individual crushing device can be one of the aforementioned crusher types, i.e. a vibrating crusher, a jaw crusher, a cone crusher and a roller crusher.

[0034] In order to determine the mining time information, the control device can be configured to call up a lower height position threshold value for the heap from the data memory and to determine the mining time information for the earliest future mining of the heap on the basis of the growth parameters.

[0035] The lower height position threshold value or a further lower height position threshold value can be used by the control device to also determine a maximum mining quantity of material that can be excavated from the heap in order to ensure that a minimum size of the heap remains after the mining of the material.

[0036] In addition or alternatively, the control device can be configured to call up an upper height position threshold value for the heap from the data memory and to determine the mining time information for the latest future mining of the heap on the basis of the growth parameters.

[0037] The data memory is preferably the data memory already mentioned above. More generally, the rock processing plant preferably comprises a data memory which is connected to the control device and preferably also to the at least one heap sensor in terms of signal transmission.

[0038] Although it is possible in principle for the control device to determine the mining time information from the detection signals of the at least one pile sensor, if necessary under consideration of the detection signals of the at least one operating sensor for determining at least one operating parameter of the rock processing plant, it should not be excluded that the control device also takes into account information input by a machine operator or other personnel when determining the mining time information. For this purpose, according to one preferred refinement of the application it can be provided that the rock processing plant comprises an input device for inputting information, wherein the input device is connected in terms of signal transmission to the control device for transmitting the information, wherein the control device is designed to determine the mining time information on the basis of the at least one detection signal and the information input into the input device in the operation with discontinuous pile mining.

[0039] The input device can be any arbitrary input device, such as a keyboard, a touch screen, etc. The input device can also be connected in terms of signal transmission to the control device by means of a cable section or a wireless circuit section, so that the control device does not necessarily have to be physically present on the rock processing plant. The connection in terms of signal transmission of the input device or also of the at least one pile sensor or / and the at least one operating sensor to the control device also applies in the case of an intermediate provision of a data memory, the information input into the input device or / and the information output by the at least one pile sensor for detecting at least one pile parameter or / and by the at least one operating sensor are stored as data in the data memory and are called up as stored data by the control device. Likewise, the input device or / and the at least one pile sensor or / and the at least one operating sensor can be connected in terms of signal transmission directly to the data memory, so that the input device can likewise transmit the information input into it directly to the data memory for storage, as the at least one pile sensor or / and the at least one operating sensor store the results of the respective detection operation of the sensor.

[0040] In the data memory, data which do not change or can only be changed at great expense during the operating service life of the rock processing plant, for example with regard to the structural mechanical configuration of the rock processing plant and its components, can be saved permanently and, for example, by the manufacturer of the rock processing plant during the manufacture of the rock processing plant or before its delivery. Although the mechanical configuration should change, for example, during maintenance or repair, the operation in which the maintenance or repair is carried out can carry out a corresponding content change to the data memory.

[0041] The data memory can be connected to the control device in terms of signal transmission, physically via signal lines or / and non-physically, for example via a radio circuit section or via transmission of optical signals. In principle, the data memory can thus be arranged separately and with a distance to the rest of the rock processing plant. The "rest of the rock processing plant" is here represented by its machine body. The machine body comprises the machine frame and all components of the rock processing plant which are connected to said machine frame, even if said components are arranged movably relative to the machine frame.

[0042] The stack sensor can be arranged in different ways in relation to the rest of the rock processing plant. For example, according to one preferred embodiment, at least one stack sensor can be arranged at the rock processing plant as a plant-supported stack sensor. Since the stack detected by the stack sensor is unloaded by an unloading conveyor which is particularly close to the stack to be detected in a sensor- like manner in space, the unloading conveyor is a possible preferred location for arranging the stack sensor. Typically, the unloading conveyor is a belt conveyor which dumps the processed material such that a stack growing in height over time is formed below the dumping longitudinal end of the unloading conveyor taking into account the lateral spacing due to the trajectory of the dumped material in the form of a parabola. The longitudinal end region of the unloading conveyor which obtains the dumping longitudinal end is then a preferred arrangement location for the stack sensor. Preferably, the longitudinal end region comprises the last 20%, particularly preferably the last 10%, of the conveying length of the unloading conveyor containing the dumping longitudinal end.

[0043] Additionally or alternatively, at least one stack sensor can be arranged as a location-fixed ground-supported stack sensor spatially remote from the rock processing plant, however in terms of signal transmission connected to said rock processing plant fixed in the surroundings of the rock processing plant. For example, at least one stack sensor can be erected or anchored on the ground by means of its own frame or support such that said stack sensor can detect the stack to be monitored by it particularly well, however remains as undamaged as possible by spatial distance from dirt or loose material flying around.

[0044] Additionally or alternatively, the at least one pile sensor can be provided movably with respect to the rock processing device, however in signal transmission connection with the rock processing device, as a mobile pile sensor. The pile sensor can be provided at a further vehicle at a construction site, at which the rock processing device is used. Likewise, the pile sensor can be provided on a drone, which flies above and / or around the pile to be detected by the at least one pile sensor, in particular according to a predetermined pattern, so that information about the pile can be detected by the pile sensor, although at different times, however preferably from the same detection site, which increases the comparability of the information about the pile detected at different times. For this purpose, the control device of the rock processing device can preferably be configured to remotely control a drone carrying the at least one pile sensor to fly according to a predetermined program over a predetermined trajectory. The predetermined trajectory can be determined in advance by a Teach-In-Verfahren and stored in a data memory. Instead of a drone, the at least one pile sensor can be provided on a remote-controlled vehicle connected to the ground, which, however, is less preferred due to the higher risk of damage caused by rougher operating conditions on typical construction sites. The term "construction site" here very broadly encompasses all locations where material to be processed by the rock processing device is produced or provided, such as, for example, quarries, gravel pits, recycling plants, construction demolition sites, etc. The term "mineral material" therefore includes both natural and processed mineral materials. The latter likewise includes construction materials as well as returned oversize particles.

[0045] The at least one pile sensor can detect the at least one pile parameter on the basis of different physical action principles. For example, the at least one pile sensor can detect the at least one pile parameter acoustically, in particular by means of ultrasound. Thus, the distance of the pile, in particular the pile top, from the pile sensor can be determined from the transit time of ultrasound waves reflected by the pile, in particular the pile top. From the known setting position of the pile sensor with respect to the machine frame of the rock processing device and the known geometry of the machine frame, the position of the pile sensor with respect to the ground surrounding the rock processing device can be derived, and from the detection signal information about the height position of the pile top can be derived.

[0046] Alternatively or additionally, the pile sensor can detect the pile and in particular the pile top by means of electromagnetic radiation. Here, a transit time measurement of reflected electromagnetic radiation, similar to the above-described ultrasound-based detection, can again enable the determination of the distance of the irradiated pile area from the pile sensor and from this information, in consideration of the known setting position of the pile sensor, the known radiation direction and the known machine dimensions, information about the height position of the irradiated pile area can be determined.

[0047] The detection of at least one pile parameter by means of electromagnetic radiation also includes the use of passive electromagnetic radiation, i.e. for example light, which is reflected by the pile. By means of such optical detection of the pile, for example by means of a camera, by means of data processing of the image processing of the optical detection result, information about the height position of the pile top or / and configuration information about the cone angle of a typically dumped conical pile can be determined if the contrast of the pile to its background is sufficient.

[0048] Additionally or alternatively, the height information or / and the configuration information of the pile can be detected tactilely in that a tactile organ, which is known in its spatial setting relative to the pile sensor, is applied to the surface of the pile starting from the known setting location of the pile sensor. In the case of multiple applications of the tactile organ, points of the pile surface can be determined and the pile configuration extrapolated.

[0049] According to an advantageous refinement of the application, the output device can be designed to output information about the type or / and the composition or / and the location of the pile material in addition to the extraction time information.

[0050] The information about the type of the pile material can be input beforehand via the input device or can be transmitted to the rock processing plant by a further device on the construction site. Further, the information about the type of the pile material at the rock processing plant itself can be determined. The information about the type of the pile material contains information about the average grain size, the grain size distribution, the grain shape, the moisture content, the abrasion resistance, the breaking behavior or also the color of the material. Similar applies to the determination and provision of information about the composition of the material. The information can be determined, for example, at the construction site by separate devices or by corresponding sensors at the rock processing plant by irradiation of the material to be irradiated with a high-energy electromagnetic beam, for example an X-ray beam, from a characteristic curve family saved in a data memory from the irradiation reply of the irradiated material.

[0051] The location of the pile material can be determined and output from the known location of the rock processing plant, for example by means of a GPS receiver of the rock processing plant, and the known location of the pile by means of the at least one pile sensor relative to the rock processing plant. The output device can output the location of the pile to be extracted in GPS coordinates and / or in coordinates relative to a reference point of the rock processing plant or / and of the construction site. Thereby, the extraction device can obtain not only information about when and, if necessary, in what quantity the material should be extracted by the extraction device, but also information about where this should take place. This significantly simplifies the orientation and targeted extraction of the extraction device when multiple piles are dumped on the construction site.

[0052] In order to make the mining time information available to third parties, in particular to mechanical operators of the extraction plant, the output device can be designed to output the information in the form of an undirected output to a receiver independently of a space region at least partially surrounding or / and adjoining the rock processing plant. This preferably means that no receiving device is required in order to reproduce the mining time information output by the output device as text comprehensible to humans or to electronic data processing devices.

[0053] The output device can thus output the mining time information in a visually perceptible manner, for example by displaying a time which shows the earliest possible point in time for the next material extraction. Instead of an absolute time, the remaining waiting period until the next point in time for extraction can be displayed. This can be done numerically or analogously, graphically or in a digital representation. For example, the waiting period until the next point in time for extraction can be shown in a digital representation by means of a digital clock with a countdown in time units, for example in seconds or in seconds and minutes. The waiting period can likewise be shown in a graphical digital representation by means of an analog clock or by means of an analog pointer instrument, for example again by means of a corresponding continuous or stepwise pointer movement by means of a countdown in time units. A purely graphical display of the waiting period is also conceivable, for example as a waiting time graphic which is dimensioned in proportion to the remaining waiting period, such as for example a waiting time bar which is proportional in length to the remaining waiting period, as a sandglass which is proportional to the remaining waiting period, etc. To this end, the output device can have a display device which is visually perceptible from outside the rock processing plant, for example the aforementioned pointer instrument or a monitor with a freely configurable graphical display or a light bar with a variable light emission size, etc.

[0054] Alternatively or additionally, the rock processing plant can have a receiving device which is designed separately from the machine body of the rock processing plant, is movable relative to the machine body and is detachable from or detached from the machine body in order to ensure that the mining time information reaches the place where it is actually required. The output device then outputs the mining time information by transmitting it to the receiving device. The receiving device itself is in turn designed to output the received mining time information perceptibly to an operator or / and to process or / and use the mining time information in order to control the mechanical components.

[0055] In principle, the receiving device can be firmly installed into other devices. This is preferably an extraction device, particularly preferably a cab of an extraction device. In a preferred refinement of the application, the receiving device is a portable receiving device, such as, for example, a smartphone, a tablet computer or a laptop. The receiving device can then be carried by the mechanical operator of the extraction device, and in turn, the mechanical operator can also be kept informed of the extraction time information itself when the mechanical operator is not at his extraction device. Thus, if the extraction device is not directly ready for material extraction at the point in time at which the extraction time information is output, timely material extraction at the at least one pile can also be initiated.

[0056] Since the rock processing device cooperates with the extraction device in order to be able to ensure operation of the rock processing device at a favorable operating point, the application also relates to a mechanical combination consisting of a rock processing device together with a separate, detached or detachable receiving device and an extraction device which extracts the piles of the rock processing device discontinuously. Preferably, the receiving device is provided in the extraction device in order to provide the extraction time information where it is directly needed, so that timely extraction of the at least one pile can be ensured.

[0057] The extraction device can be a shovel or a wheel loader, depending on the design of the construction site at which the rock processing device or the mechanical combination is used.

[0058] The receiving device can output the extraction time information to the mechanical operator of the extraction device in a graphical or / and acoustic manner, for example also via a head-up display, so that after being informed of the extraction time information and, if necessary, of the location of the pile to be extracted, the mechanical operator can take the necessary action in order to initiate timely extraction of the pile. Additionally or alternatively, the receiving device can be coupled in terms of signal transmission to operating components of the extraction device which are associated with transport and can actuate them in accordance with the extraction time information. The operating components associated with transport can be, for example, at least one actuator at the extraction device which moves an extraction tool of the extraction device, such as, for example, a shovel or a bucket of a wheel loader, in order to fill it.

[0059] Thus, a partially automated operation of the mechanical operator of the extraction device or even a fully automated operation of the extraction device is supported by the receiving device, if necessary by at least one further control device on the side of the extraction device.

[0060] The at least one operating parameter of the rock processing device, in particular a material parameter, or / and a pile parameter, can be detected qualitatively or / and quantitatively. If more than one parameter is detected in a sensor-like manner, a part of the parameters can be detected qualitatively and another part can be detected quantitatively. Furthermore, it is also conceivable that at least one parameter is detected qualitatively and quantitatively.

[0061] To determine the amount of processed and / or extracted material, the rock processing plant can have a weighing device on the processing side, which constitutes a weighing of the processed material, or / and the extraction plant can have a weighing device on the extraction side, which constitutes a weighing of the extracted stock material.

[0062] The rock processing plant can be part of a rock processing facility, which comprises a plurality of rock processing plants. Preferably, the plurality of rock processing plants works in connection in a range, in which the rock processing plant upstream in the material flow supplies the material loading device of the rock processing plant downstream with its one or more final grain products. Such a rock processing facility is likewise to be understood as a rock processing plant in the sense of the present application, which has a plurality of rock processing sub-plants.

[0063] The type of material can be determined by one or more qualitative parameters or / and one or more quantitative parameters.

For example, the parameters can have qualitative contents such as "hard", "medium hard", "soft", "good crushability", "medium crushability", "poor crushability", "low moisture", "medium moisture", "high moisture", etc. The qualitative classification can have more than three levels.

[0065] The density can be determined quantitatively, for example, from an optical volume measurement, for example, while weighing by means of a scale integrated into the conveying device. The moisture of the material can be determined by means of a corresponding moisture sensor. The abrasiveness can be determined by means of an LCPC test.

[0072] In Figure 1 the construction site is generally designated by 10. The central working device of the construction site 10 is a rock processing plant 12, which has a vibrating crusher 14 as a crushing device and a pre-sieve 16 and a post-sieve 18 as screening devices. Here, the construction site is preferably a quarry, however, it can also be a recycling station or a demolition site of one or more buildings.

[0073] The material M to be processed by the rock processing plant 12, i.e. to be sorted according to size and crushed, is loaded discontinuously by a loader 20 as a loading device of the rock processing plant 12 into a material loading device 22 having a material buffer 24 in the form of a hopper.

[0074] A vibrating conveyor, which is configured as a trough conveyor 26, conveys the material M from the material loading device 22 to the pre-sieve 16, which has two pre-sieve plates 16a and 16b, of which the upper pre-sieve plate 16a has a larger mesh size and separates and conveys to the vibrating crusher 14 the particle size that needs to be crushed according to the respective regulations for the final granulate product to be achieved.

[0075] The particles falling through the upper pre-sieve plate 16a are further sorted by the lower pre-sieve plate 16b into a useful particle fraction 28, which corresponds to the technical specifications of the final granulate product to be achieved, and a too small particle fraction 30, which has a small particle size so that it cannot be used as useful particles.

[0076] ​​The number of piles or fractions shown in the embodiments is merely exemplary. It can be greater or less than the values given in the examples. Furthermore, the undersized particle fraction 30 explained as waste in the present example can also be a useful particle fraction, provided that the particle size range accumulated in the fraction 30 can be used for other applications.

[0077] The usable particle fraction 28 is increased with the crushed material output by the vibrating crusher 14 and is conveyed to the post screen 18 by a first conveying device 32 in the configuration of a belt conveyor. In the embodiment shown, the post screen 18 likewise has two screen decks or post screen decks 18a and 18b, of which the upper post screen deck 18a has a larger screen opening size. The upper post screen deck 18a enables the useful particles to fall through its screen openings and to be sorted out of an oversized particle fraction 34 having a particle size greater than the maximum desired particle size of the useful particles. The oversized particle fraction 34 is led back to the material input or pre-screen 16 of the vibrating crusher 14 by an oversized particle conveying device 36. In the embodiment shown, the oversized particle conveying device 36 is configured as a belt conveyor.

[0078] The usable particles of the usable particle fraction 28 thus include the oversized particles and the useful particles. In contrast to the view in the present embodiment, the oversized particle conveying device 36 can be pivoted outward, for example, from a machine frame 50 of the rock processing plant 12, so that the oversized particle fraction 34 is stored without being led back.

[0079] The useful particles falling through the screen openings of the upper post screen deck 18a are further separated by the lower post screen deck 18b into a fine particle fraction 38 having a smaller particle size and an intermediate particle fraction 40 having a larger particle size.

[0080] The fine particle fraction 38 is accumulated into a fine particle pile 44 by a fine particle discharge conveying device 42 in the configuration of a belt conveyor and is stored.

[0081] The intermediate particle fraction 40 is accumulated into an intermediate particle pile 48 in the configuration of a belt conveyor by an intermediate particle discharge conveying device 46 likewise in the configuration of a belt conveyor and is stored. Figure 1 The intermediate particle pile 48 is not shown in the Figure 2 and is only shown in a coarse schematic in the

[0082] As a central structure, the rock processing plant 12 has a machine frame 50 at which the mentioned device components are fixed or supported directly or indirectly. As a central power source, the rock processing plant 12 has a diesel internal combustion engine 52 supported at the machine frame 50, which generates all the energy consumed by the rock processing plant 12, provided that the energy is not stored in an energy store, such as, for example, a battery. Additionally, the rock processing plant 12, provided that it is present, can be connected to a construction site current on the construction site side.

[0083] The rock processing plant 12, which can be part of a rock processing plant having a plurality of rock processing plants arranged in a common material flow, is in the example shown a mobile, more precisely automatically traveling rock processing plant 12, which has a caterpillar traveling mechanism 54, which enables automatic site changes without an external traction machine via a hydraulic motor 56 as drive of the rock processing plant 12.

[0084] The extraction (abbau) of the heaps of useful particle 44 and 48 and of the oversize particle fraction 30 is discontinuously carried out by one or more wheel loaders 58 as exemplary extraction plants. The heap of the oversize particle fraction 30 must also be regularly extracted in order to ensure the operation of the rock processing plant 12 without interruption.

[0085] For an as favorable as possible operation control, the rock processing plant 12 has the following plant components, which are described below according to the Figure 2

[0086] The rock processing plant 12 comprises a control device 60, for example in the configuration of an electronic data processing facility with integrated circuits, which controls the operation of the plant components. For this purpose, the control device 60 can for example directly actuate the drives of the plant components or actuators, which in turn can move the components.

[0087] The control device 60 is connected in signal transmission with a data memory 62 for data exchange and with an input device 64 for inputting information. Via the input device 64, for example a touchscreen, tablet, keyboard, etc., information can be input onto the input device 64 and stored by the input device in the data memory 62.

[0088] Furthermore, the control device 60 is connected in signal transmission with an output device 66 in order to output information.

[0089] The rock processing plant 12 also has various sensors for information acquisition about its operating state, which are connected in signal transmission with the control device 60 and thus indirectly with the data memory 62 in the example shown. The sensors are only shown in Figure 2

[0090] A camera 70 is arranged at the carriage 68, which records an image of the material filling device 22 with the material buffer 24 and transmits it to the control device 60 for image processing. By means of the camera 70 and by image processing of the image recorded by the camera of the material buffer 24 and the material filling device 22, the filling degree of the local material buffer 24 is determined by the control device with the data relationships stored in the data memory 22.

[0091] ​​Further, the vibration amplitude and the vibration frequency of the trough conveyor 26 are detected by a not shown drive of the trough conveyor and transmitted to the control device 60, which from these information determines the conveying speed of the trough conveyor 26 and determines the conveying power of the trough conveyor 26 towards the vibrating crusher 14 taking into account the local filling level of the material buffer 24.

[0092] By predetermined data relations, which are generated or / and developed by means of artificial intelligence methods, the control device 60 can recognize from the image information of the camera 70 the grain size distribution and even the material type in the material M in the material buffer 24.

[0093] In the vibrating crusher 14, an upper vibration rocker 72 and a lower vibration rocker 74 are provided in a manner known per se, wherein the rotational position of the upper vibration rocker 72 is detected by a rotational position sensor 76 and the rotational position of the lower vibration rocker 74 is detected by a rotational position sensor 78 and transmitted to the control device 60. By means of the rotational position sensors 76 and 78, the control device 60 can also determine the crushing gap width of the upper crushing gap at the upper vibration rocker 72 and the crushing gap width of the lower crushing gap at the lower vibration rocker 74.

[0094] A rotational speed sensor 80 determines the rotational speed of the crushing rotor of the vibrating crusher 14 and transmits it to the control device 60.

[0095] At particularly wear-prone components, such as for example at the impact bars, the vibration rockers, the vibration plates and the vibration beams, wear sensors can be provided, which record the wear progression, usually in the form of a wear level, and communicate it to the control device 60. In the shown example, for better overview, only a wear sensor arrangement 82 is shown at the lower vibration rocker 74.

[0096] In the first conveying device 32, a first belt scale 84 is provided, which detects the weight or mass of the material, which is transported through it at the first conveying device 32, of the available particle fraction 28. Via a rotational speed sensor 86 in a deflection roller of the conveyor belt of the first conveying device 32, the control device 60 can determine the conveying speed of the first conveying device 32 and can determine the conveying power of the first conveying device 32 in combination with the detection signal of the first belt scale 84.

[0097] A second belt scale 88 is provided in the fine grain discharge conveyor device 42 and detects the mass or weight of the fine grain portion 38 passing it on the belt of the fine grain discharge conveyor device 42. The conveying speed of the fine grain discharge conveyor device 42 can also be determined by means of a rotational speed sensor 90 in the deflection roller of the conveyor belt of the fine grain discharge conveyor device 42 and the conveying power of the fine grain discharge conveyor device 42 is determined by the control device 60 in combination with the detection signal of the second belt scale 88.

[0098] A third belt scale 92 is provided in the oversize grain conveyor device 36 and determines the weight or mass of the oversize grain portion 34 passing it on the conveyor belt of the oversize grain conveyor device 36. A rotational speed sensor 94 of the deflection roller of the conveyor belt of the oversize grain conveyor device 36 determines the conveying speed of the oversize grain conveyor device 36 and transmits it to the control device 60, which can determine the conveying power of the oversize grain conveyor device in combination with the detection signal of the third belt scale 92.

[0099] A first pile sensor 96 is provided at the longitudinal end of the discharge side of the fine grain discharge conveyor device 42, which records an image of the fine grain pile 44 as a camera and transmits it as image information to the control device 60, which identifies the contour of the fine grain pile 48 by image processing and determines the configuration of the fine grain pile 48 on the basis of the identified contour on the basis of the known imaging data of the camera of the first pile sensor 96 and determines the volume of the fine grain pile therefrom. The control device 60 can here take as a starting point for the simplification of its information determination the ideal conical configuration of the fine grain pile 48 without significant errors and determine the volume of the ideal cone approximating the actual fine grain pile 48. Thus, when the pile sensor determines the diameter D of the base of the pile and the height h of the pile, as is shown in Figure 2 and 3 with the example of the pile 48, this can be sufficient.

[0100] A second pile sensor 98 is shown in Figure 1 which is used alternatively or additionally. The second pile sensor 98 comprises a flyable drone as a carrier, which can be remotely controlled in its movement by the control device 60. The second pile sensor 98 is also used to determine at least the height of the fine grain pile 48, preferably however to determine its configuration and thus its volume. The advantage in the use of a drone or a sensor mounted at an elevated location, for example at a high pole or support, is that the sensor can detect the height or / and the shape or / and the volume of more than one pile. Then, the number of sensors, which is less than the number of piles to be detected in total at the rock processing device 12, at the rock processing facility or at the construction site 10, can be sufficient to detect each pile to be detected. Then preferably, exactly one sensor is sufficient to practically detect all piles to be detected.

[0101] Each unloading conveyor that generates a pile preferably has at least one pile sensor or works in conjunction with a pile sensor.

[0102] The remaining unloading and conveying equipment, such as, for example, medium particle unloading and conveying equipment 46 and small particle unloading and conveying equipment 29, preferably also have belt scales and speed sensors for detecting the amount of material being transported on the respective conveying equipment, the conveying speed, and thus the conveying power.

[0103] The following is a detailed explanation of output device 66:

[0104] Output device 66 may, for example, have projection device 100 at support frame 68, so as to... Figure 2 The projection marks within the total filling area 102, which is the same as the output opening of the material buffer 24, are shown in the diagram. The total filling area 102 is selected such that particles falling along the direction of gravity reach the material filling device 22 instead of falling directly onto the pre-screen 16.

[0105] Output device 66 further includes a transmit / receive unit 104, which can transmit data via radio in a suitable data protocol to a receiving device configured to communicate with it, such as... Figure 4 and 5 The receiving device 106 in the middle and can be received by the receiving device.

[0106] Furthermore, the output device 66 has a first display device 108, for example, in a monitor configuration, for externally perceptible display of time information for the next material loading into the material loading device 22. Similarly, in the illustrated embodiment, the output device 66 may have a second display device 110, again for example, a monitor, for externally perceptible display of time and location information for the next pile mining operation. For this purpose, the display device 110 displays not only the time information of when the next pile mining operation should begin, but also the location information of which pile should be mined at the given time, and, if necessary, the quantity of the mentioned pile to be mined.

[0107] Furthermore, the excavator 20 includes a transmitting / receiving device 112 with a data storage device configured to communicate with the transmitting / receiving unit 104 of the rock processing equipment 12. Therefore, the transmitting / receiving device 112 can transmit important data about the excavator 20 to the transmitting / receiving unit 104, such as, for example, the capacity of its bucket 21 as its loading tool and / or its current GPS data.

[0108] Correspondingly, the wheel loader 58 comprises a transmitting / receiving device 114 with a data memory, which is set up for communication with the transmitting / receiving unit 104 of the rock processing plant 12. Thus, the transmitting / receiving device 112 can transmit important data about the wheel loader 58 to the transmitting / receiving unit, such as, for example, its capacity as its excavation tool, the bucket 59, or / and its current GPS data.

[0109] The data memory 62 contains, in the example shown, a plurality of data relationships which associate operating or / and material parameters with one another. These data relationships can be determined beforehand by test runs with targeted parameter variations and saved in the data memory 62. For more complex, multi-dimensional data relationships, in particular, the use of artificial intelligence methods helps to determine the functional relationships between the operating parameters or / and the material parameters. The data relationships thus determined can be continuously verified, refined or / and corrected in the continued operation of the rock processing plant 12, again preferably with the aid of artificial intelligence methods.

[0110] The discontinuous material filling of course results in a surging material filling, in which the filling material surges through the size limit of the bucket 21 of the excavator 20. The time interval between two discontinuous material fillings is unpredictable and fluctuates.

[0111] In order to avoid disturbances in the work progress of the rock processing plant 12, the control device 60 determines, from the detection signals of one or a plurality of the aforementioned sensors, time information which represents the implementation time in the future, in particular the next time, of the material filling into the material filling device 22.

[0112] To this end, the control device 60 preferably takes into account the determined locally differentiated filling level of the material buffer 24 and the conveying power of the trough conveyor 26 and, for example, the undersize particle conveying device 29 and the first conveying device 32. A bilanziell observation of the material flow of the trough conveyor 26 into the vibrating crusher 14 and of the material flow of the undersize particle conveying device 29 and the first conveying device 32 out of the vibrating crusher 14 shows whether the filling level of the vibrating crusher 14 changes over time, for example, rises or falls, in turn giving a measure of whether the conveying power of the trough conveyor 26 can be maintained or must be changed. The conveying power of the trough conveyor 26 is decisive, however, for how quickly the material buffer 24 should be emptied and reloaded with material. Alternatively or additionally, a sensor which directly detects the filling level of the vibrating crusher 14 can also be provided at the rock processing plant 12.

[0113] Likewise, the control device 60 takes into account the amount of oversize particles which are introduced back, since the oversize particle fraction 34 likewise contributes to the filling level of the material buffer 24.

[0114] The predefined data relationships stored in the data memory 62 can associate, as input variables, the detection signals of the camera 70, the first belt scale 84, the rotational speed sensor 86, the belt scale and the rotational speed sensor at the undersize particle discharge conveyor device and the belt scale 92 and the rotational speed sensor 94 of the oversize particle conveyor device 36 and, if necessary, taking into account the case that the excavator 20 is removed from the material loading device 22, the size of the dipper 21 of the excavator 20 with, as output variable, time information which states when the next material loading into the material loading device 22 should take place. The time information can be displayed perceptible for each person in the visual field of the rock processing plant 20 in a suitable manner, for example as a sandglass, a waiting time bar, a time countdown or an analog clock view, on the one hand at the first output device 108.

[0115] The time information can furthermore be transmitted by the transmitting / receiving unit 104 to a mobile receiving device 106 which is available to the machine operator of the excavator 20. The mobile receiving device 106 can be a portable mobile device, like a mobile phone, a tablet computer or the like or can be fixedly installed in the excavator 20 as part of its control device and left in the excavator 20.

[0116] In Figure 4 exemplarily shown in Fig. 6, the display of the time information at the receiving device 106 is shown not only in the upper half by the pointer display 107a in a graphical manner, but also in the lower half by the time countdown 107b in an alphanumeric manner. In the case shown, the next material loading is expected in 00 minutes and 45 seconds.

[0117] The control device 60 can thus control the discontinuous material loading step by step and ensure a material flow in the rock processing plant 12 which is as good as possible despite the discontinuous material loading.

[0118] By a local or partial resolution of the filling level in the material loading device 22 or in the material buffer 24, the control device 60 can furthermore, according to further data relationships stored in the data memory 62, control or give location information about a preferred material loading location within the total loading area 102 of the material buffer 24 or of the material loading device 22 not only in terms of time, but also in terms of location within the total loading area 102 for the next material loading.

[0119] It is thereby possible to promote, by the control device 60, a loading of the material buffer 24 which is as advantageous as possible across the total operating time of the rock processing plant 12 for the respective constructional manner of the material loading device 22 and the rock processing plant 12 which can be recognized in parameter form in the data memory 62 in a manner available to the control device 60.

[0120] Thus, local overfilling of the material buffer 24 and direct filling of material onto the prescreen 16 can be avoided. Furthermore, material can be filled in places where the degree of filling within the material buffer 24 locally decreases significantly in order to ensure a favorable material bed in the material filling device 22.

[0121] Thus, the control device 60 can output the location information for the mechanical operator of the excavator 20 as to where the next material filling should take place within the total filling area 102 in accordance with the predetermined data relationship.

[0122] The output device 66 can output the location information visibly for everyone by means of the projection device 100, which projects a marker within the total filling area 102 or within the material buffer 24 at the site where the next material filling should take place.

[0123] Additionally or alternatively, the location information can be output to the mechanical operator of the excavator 20 via the receiving device 106, as has been the case for the time information for the next material filling. Figure 5 An embodiment of the location information output is shown. The receiving device 106 shows a schematic depiction 197c of the material buffer 24 with the total filling area 102 and marks the desired filling location for the next material filling within the total filling area 102 by means of an appropriate marker 116. Additionally, the preferred unloading height or unloading height range to be adhered to can also be given quantitatively, for example in meters or / and centimeters, or qualitatively, for example by means of a qualitative unloading height parameter specification such as "low", "intermediate" and "high". The additional height information can be easily realized, in particular, when the location information is communicated to a partially automated excavator control device if necessary.

[0124] By means of the first or / and second pile sensors 96 or 98 at the respective unloading conveyor devices 29, 42 and 46, the control device 60 can detect the growth of the piles 30, 44 and 48 produced by the rock processing device 12 in terms of the bulk density, possibly in a derived manner, taking into account material parameters such as the type, grain size and grain size distribution of the material being filled, and, primarily, the change or growth rate of the respective pile, and, in the case of the application of the previously generated and stored data relationship, determine the extraction time information: when a particular pile should be extracted by the wheel loader 58. In this way, it can be avoided that a pile grows too much and blocks the unloading via the unloading conveyor device producing the respective pile.

[0125] Furthermore, the control device can use the data relationships determined therefor to determine further mining information, which specifies in which range mining should take place, taking into account material parameters, such as grain size and grain size distribution and density.

[0126] If the rock processing plant 12, as in the present case of application, produces a plurality of piles, the output device 66 also outputs further mining information, which identifies the pile to which the mining time information relates.

[0127] The control device 60 can display the mining time information and the further mining information perceptibly at a second display device 110 for each person in the field of vision of the rock processing plant 12. Additionally or alternatively, the output device 66 can transmit the information for the next pile mining to a receiving device 106 via the transmitting / receiving unit 104, where it is output to the mechanical operator of the wheel loader in a graphical manner or / and in an alphanumeric manner.

[0128] Finally, the control device 60 can control the operating parameters of the rock processing plant 12 in accordance with the detection signals of suitable sensors, so that in the illustrated embodiment a predetermined desired ratio of the amount of fine particles to the amount of medium particles is achieved. Likewise, the control device 60 can control the rock processing plant 12 on the basis of correspondingly prepared data relationships, so that the energy consumption of the rock processing plant 12 per unit amount of processed mineral material reaches at least one local minimum or is reduced. Additionally or alternatively, the control device 60 can control the rock processing plant 12 in the case of application of correspondingly prepared data relationships, so that an amount of oversized particles is introduced back which is advantageous for the respective crushing process, so that in one crushing gap or in a plurality of crushing gaps there is sufficient support of the oversized particles due to the pre-crushed oversized particles. In fact, an operation in which the goal is to minimize or eliminate oversized particles is not necessarily the most economical operation of the rock processing plant 12 due to the advantageous effect of the oversized particles in the crushing gap as support particles. That is, a very small amount of oversized particles usually means an oversized amount of over-crushed material, which is often undesirable. If the amount of material introduced back is reduced, the quality of the end product is also usually reduced, since it then contains less multiply crushed material.

[0129] Here, the control device 60 can also strive for an operation of the rock processing plant 12 on the basis of a target variable or a plurality of target variables with further pre-set boundary conditions, which it can use, which were determined beforehand by test runs with targeted parameter variations, so that, for example, the production of useful particles of different grain sizes with predetermined amount ratios is striven for with as little energy consumption as possible and with as advantageous an amount of oversized particles introduced back as possible.

[0130] The control device 60 can change the conveying speed of one or more conveying devices, can change the crushing gap width, in particular the crushing gap width of the upper crushing gap or / and of the lower crushing gap, can change the rotor rotational speed, can control the material filling into the material filling device 22 in terms of location and in terms of time, etc. in order to set the operation of the rock processing plant 12 in accordance with the output variable of at least one used data relationship.

[0131] The input variables for the operation optimization can be the size or / and height or / and growth of the stock of useful particles, here for example of the stocks 44 and 48, the size or / and height or / and growth of the stock of undersize particles 30, the amount of oversize particles introduced back, the grain size of the filling and the grain size distribution of the filling, the material parameters which can be determined beforehand via the input device 64. The input material parameters can include at least one of the material type, the moisture, the hardness, the density, the crushability, the abrasiveness, the share of impurities in the filling or / and in the processed material, etc. The list is not final. In the discharge conveying devices, the grain size and the grain size distribution, if necessary also the particle shape, can be determined by means of cameras together with image processing connected downstream. The grain size and the grain size distribution in the discharge conveying devices can additionally or alternatively be determined by means of the occupation of the screening devices upstream of the respective discharge conveying device in the material flow. Additionally or alternatively, the desired desired amount of the respective end product can be used as an input variable for the operation optimization.

[0132] By applying artificial intelligence methods, the control device 60, in the desired case with the participation of an efficient external data processing device, can continuously improve the target accuracy of the saved data relationships by its actual operation and the data and knowledge collected therefrom.

[0133] Thus, the rock processing plant 12 can not only optimize its own operation as such, but in principle gradually take over the organization of the entire construction site in the vicinity of the rock processing plant 12.
