    Finally, the invention relates to a method for securing a inventively reached, invention breaker device against overload.
    STATE OF THE ART
    Crushing machines, so-called crushers or mills are used to comminute lumpy feed material. Typical feed materials are soft rock, e.g. Sandstone or limestone, hard rock, e.g. Granite or dolomite: steel-poor concrete demolition, bricks, A * sphait, etc. Nowadays, such crushers are increasingly compact and mobile, so that the crushers can easily reach the location - ·· * # ··· ** · **. can be brought to cer HUi.Dereitung or their position

    The crushing element is driven by a drive motor d tvpischerv Iron as a diesel engine is listed. In doing so, the transmission of power between the drive motor and the cheeky learner usually takes place via a drive belt, in particular a V-belt, owing to the small loss of power.

Finally, the said clutches anyway need a not negligible space in the drive room, especially in mobile. Crushers are difficult to provide. Due to the constantly stricter exhaust gas regulations for the drive motors, this clutch installation space for the necessary engine technology, such as catalysts, exhaust gas recirculation,
    Fuel injection, larger radiator, etc., urgently needed.
    OBJECT OF THE INVENTION
    It is therefore an object of the present invention, the above-mentioned. To avoid disadvantages. In particular, space should be created in the Anrriebsraum and created a way to detect a clogging or overloading of the crusher in good time and be able to initiate countermeasures.
    PRESENTATION OF THE INVENTION
    To gain space in the drive space is dispensed according to the invention to a clutch in the drive compartment. Accordingly, also eliminates necessary maintenance of the clutch. That a drive pulley is rigidly connected to a drive motor. A drive belt connects the
    Drive pulley with a driven pulley, which in turn is connected to a crushing element or drives this.
    According to the invention, an axle coupling is realized by varying the tension of the drive belt by means of a tensioning device. Uncoupling is thus achieved by completely releasing the tension, so that durchrntscht the belt or the drive pulley. By means of .4 «+
    Increasing the voltage is engaged and a positive connection between the drive pulley, drive belt and driven pulley produced. As a result, transmissions of the drive belt, the power of the drive motor via the drive pulley on the driven pulley and thus on the refractive element. Accordingly, it is in a crusher device according to the invention, preferably cone crusher, jaw crusher or impact mill, with a drive pulley driving a driven pulley and driven by a drive motor drive pulley and a Ar.triebsriemenscheibe and driven pulley interconnecting, endless peripheral drive belt, provided that the drive pulley rigid and direct is connected to the drive motor and a clamping device is provided to vary the voltage of the drive belt at least during operation of the drive motor.
    To minimize friction losses, the tensioner is designed as a rotatable tension pulley, not as a rigid guide through which the belt slips. The clamping disc is pressed by means of a mechanism, preferably hydraulically, with a feed movement against the drive belt to increase the voltage. To lower the tension of the drive belt, the tension pulley is moved away from the drive belt. Therefore, in a preferred embodiment, the crusher device of the present invention provides that the chucking device is nanaelt by: a chucking pulley moving over a preferably hydraulically caused advancing movement.
    Kittels a hydraulic cylinder, the delivery movement exporting mechanism can be realized very efficient and space-saving. The hydraulic cylinder can in this case in turn be operated with the drive motor or via a hydraulic unit driven by the drive motor. Thus, in a particularly preferred embodiment, it is the * ^ * * *. *. *. * #. *. *. * Φ β A ι ♦ * * * * * * *. The breaker device according to the invention is provided, as a result of which the hydraulically effected feed movement was effected by means of a hydraulic cylinder.
    In order to be able to adjust the tension of the drive belt in a targeted manner, the hydraulic cylinder is actuated via an S 'control device. In this case, the control device may have different parameters such as the Hari-e of the / lUzgabematenaj_s in the choice of the drive belt tension berac.csj.ch ^. In addition, the controller applies a scrolling function by constantly monitoring the rotational speeds of the drive pulley and the driven pulley which are measured by means of speed sensors. This is w_chzia in order to be able to counteract countermeasures when the crusher becomes clogged. Therefore, it is provided in a preferred A.usf ührur.gsvariante the breaker device according to the invention that a control device driving the tensioning device is provided, which controls the feed movement of the tensioning disk via the hydraulic cylinder and thus the tension of the
    Drive belt sets.
    The course of the drive belt between the
    Drive pulley and the driven pulley has a horizontal component. Accordingly, there are air. Drive belts one upper and one lower strand. A particularly space-saving embodiment of the clamping device is realized by the clamping disk engages the lower run of the drive belt. Therefore, in a particularly preferred embodiment, it is provided that the tensioning disc engages the lower run of the drive belt. It is understood, however, that variants are also conceivable, where the tensioning disc engages the upper run of the drive belt.
    The drive belt in the relaxed state, which is a disengaged position of the seat, can not be easily detached from the belt. * · «» »€ * * * 4 * · · · · · · ·
    Drive pulley or the driven pulley falls down, guide plates are provided on which the relaxed drive belt at least partially rests. These guide plates can be arranged at lying positions: under the upper run of the drive belt; under the lower run of the drive belt; outside the drive belt, at least partially surrounding the drive pulley; and outside the drive belt, the output pulley at least partially surrounding. Accordingly, it is provided in a preferred embodiment of the breaker device according to the invention that guide plates are provided below the upper run of the drive belt and / or below the lower run of the drive belt and / or outside of the drive belt, the
    Drive pulley at least partially surrounding and / or outside of the drive belt, the driven pulley are arranged at least partially surrounding.
    Since at the lower run the tension disc engages to tension the drive belt, not the entire lower run of the drive belt can be surrounded by a continuous guide plate. But there may be several, typically two, guide plates under the lower run of the drive belt, between which he attacked the tension pulley on the drive belt. can. In this case, the guide plates, which are below the lower run of the drive belt a.ngeordn.et pass into those guide plates or be integral with those guide plates, which are arranged outside the drive belt, the drive pulley or the driven pulley at least partially surrounding. Therefore, it is provided in a particularly preferred A.usführungsform the breaker device according to the invention that a guide plate, which is arranged under the lower run of the drive belt, merges into that guide plate, which outside the Μ / # φ M "··. , , «·. *. , ·· ♦ • t * * *· * * * * * * I I · 1 «* * *« * * * * * ♦ * * * * * * *

Respectively, it is provided in a further particularly preferred embodiment of the breaker device according to the invention that eir. Guide plate, which is arranged under the lower run of the drive belt, merges into that Führungsb_ech, which is arranged outside the drive belt, the driven pulley at least partially surrounding.
    As already mentioned, a Einfczw. Disengaging achieved by increasing or decreasing the tension of the drive belt. To start the Brechervorrichcung, the tension of the drive belt from a state where no force is transmitted from the drive pulley to the driven pulley enough to move the driven pulley and thus the crushing element, is transferred to a state in which the drive belt from a coupling during engagement sufficiently large force is transmitted from the drive pulley to the driven pulley to move the Aotriebsriemenscheibe and thus the refractive element. The tension of the drive belt is increased accordingly. Accordingly, it is in a method for starting a crusher device according to the invention with a driven pulley driving a driven pulley and driven by a drive motor. Drive pulley and a drive pulley and driven pulley connecting, endless rotating drive belt according to the invention provided that the drive pulley is driven by the Antriebsmctor directly without the interposition of a clutch and the tension of the drive belt during startup of a voltage with which, the .Abtriebsriemenscheibe moving force is transmitted from the .Antriebsriemenscheibe on the driven pulley, is increased to a voltage with which the ".......... Λ ** ·· · · ·; l «. > - ......! : ..... * * «« * «· ·· * · · * * • 4 f» ·· ·· · * **
    Output pulley is driven by the drive pulley by means of the drive belt.
    As already mentioned, the increase in the voltage rr.itte_s of a hydraulic cylinder, which is controlled by a control device, which in turn continuously controls the rotational speeds of the drive pulley and the driven pulley by means of speed sensors. In this way, the control unit determines whether, after a certain, predeterminable time, a likewise specifiable speed ratio exists between the drive belt pulley and the driven pulley. In this way, on the one hand be gently engaged. If the predetermined speed ratio is not reached after the predetermined period of time, this is detected as a fault condition, whereupon, for example, automatically disengaged or the drive motor can be turned off. On the other hand, the predetermined speed ratio does not have to correspond to the gear ratio of the driven pulley to the drive pulley, ie. it can be given a certain amount of slip deliberately, which at the same speed of the drive pulley different speeds of the driven pulley can be adjusted. In addition, by providing some slip, engine stalling, e.g. in case of sudden constipation, sometimes avoided. Therefore, it is provided in a preferred embodiment of the method according to the invention that in the started state of the breaker device, the ratio of the speed of the driven pulley to the speed of the drive pulley the gear ratio of the pulleys or a proportion of this ratio between 90% and 100%, preferably between 97% and 100 %, corresponds.
    A successful engagement or starting operation is when the speed ratio of the pulleys makes up at least 90% of the transmission ratio of the pulleys. I ············································ »
    Such a speed ratio of the pulleys defines the angefahrer.en state. It is important that the approached state is actually reached even after a certain period of time of typically 5 to 20 seconds, the concrete time depends on the size of the refractive element, for example, the diameter of a baffle rotor of an impact mill. If you engage too quickly or start up, there is a risk of stalling the Moror; if the coupling is too slow or start up, there is a lot of wear heat or wear; if it is determined that the started condition has not been reached within the stated period of time, the soution device shuts off the drive motor in order to prevent damage, in particular to the drive belt.
    Thus, in a particularly preferred embodiment of the method according to the invention, it is provided that the ratio of the output pulley speed to the drive pulley speed during startup is monitored by speed sensors connected to a control device and not reaching 0, S times the transmission ratio of the pulleys After a period of 5 to 20 seconds, the controller turns off the Ar.triebsmotor.
    If the predetermined speed ratio of the driven pulley to the driven pulley decreases after start-up, overloading may occur due to an excessive amount of material being fed. Instead of stopping the engine, it may therefore be useful to throttle the material supply to allow the processing of the excessive amount of Marerial, which should again set the predetermined Drehzahlverhit. For this purpose, the control device continuously evaluates the rotational speeds of the driven pulley and the drive pulley measured by means of the rotational speed sensors and, if necessary, controls the supply of material corresponding to or 1 Ί. • »· * * * * *****! »» 4 »* f * * · · *. , «*« · * * * «♦ causes a throttling. Of course, if the preset speed ratio returns after the excessive amount of material has been processed, the controller can again cause a gradual increase in the supply of material. In practice, it has been shown that throttling the material supply makes sense if, when approached, the speed ratio of the driven pulley to the drive pulley drops below 70%, preferably below 8%, of the transmission ratio of the pulleys. Therefore, it is provided according to the invention in a method for hedging an invention according to invention, breaker device against overload according to the invention that the ratio of the speed of the driven pulley to the speed of the drive pulley is monitored after starting by the speed sensors connected to the control device and falls below the 0.7- times, preferably 0.8 times, the transmission ratio of the pulleys cie control device reduces the supply of material or stops completely.
    Alternatively, the reduction or stop of the supply of material can be carried out only after a Nachspannzeit in which the tension of the drive belt is increased. If it is possible in this Nachspannzeit by the higher belt tension and thus by the better power transmission, the speed ratio of the pulleys about 0.7 times, preferably 0.8 times, to lift the gear ratio of the pulleys, so is omitted after the post-tensioning a reduction or stop the supply of material. If, on the other hand, after the post-tensioning time, the speed ratio of the pulleys is still smaller than 0.7 times, preferably 0.8 times, the transmission ratio of the pulleys, the material supply is reduced or stopped. Accordingly, it is provided in a particularly preferred embodiment of the method according to the invention that before reducing or stopping the supply of material for a period of Nachspar.nzeit causes an increase in the tension of the drive belt and the material supply only reduces or stops when after the Nachspannzeit the speed ratio of the pulleys after more than 0.7 times, preferably 3.8 times, the transmission ratio of the pulleys below.
    In practice, it has been shown that the post-tensioning time should be short, a maximum of 5 seconds, preferably a maximum of 3 seconds. Therefore, a particularly preferred embodiment of the method according to the invention provides that the post-tensioning time is a maximum of 5 seconds, more preferably a maximum of 3 seconds.

    WAYS TO. EMBODIMENT OF THE INVENTION
    Fig. 1 shows a side view of a crusher according to the invention for comminuting feed material, such as e.g. Rock, concrete demolition, asphalt, etc. The feed material is typically fed into a hopper and fed via a material supply 10, which is designed for example as a vibratory conveyor, a baffle rotor (not shown). That in the illustrated embodiment is to be assumed by a Rrall mill as a breaker device. Of course, the invention is not limited to impact mills, but can in other. Breaking devices, for example, jaw crushers, cone crushers or other special crushers are also realized.
    The baffle rotor has blow bars for crushing the feed material and has a mass of typically 3 to 7 tons. The impact rotor is rotatably mounted around an impact rotor rotational axis 17 (cf., Fig. 2 or Fig. 4) and rigidly connected to an output pulley 3.
    The driven pulley 3 is connected via a drive belt 1 with a drive pulley 2. The drive pulley 2 is rigidly connected - without a clutch - to a drive motor 11 and is rotated by the latter about its drive motor rotation axis 9. The drive motor 11 includes a radiator and at least one hydraulic unit to operate hydraulic elements, wherein the radiator and hydraulic unit in Fig. 1, however, are not visible.
    In order to produce a frictional connection between the drive belt pulley 2, the drive belt 1 and the driven pulley 3, a tensioning device 12 is provided (cf., FIG. 2 or 4), which comprises a tension pulley 4.
    The clamping disk 4 is pressed against the cylinder by means of a hydraulic cylinder 5 which is mounted on the frame of the breaker device. * * ·· · t · a% * «* * * * * *
    Drive belt 1 is pressed, whereby it is tensioned and slippage of the drive belt 1 and the drive pulley 2 is avoided or reduced, which in turn has a rotation of the driven pulley 3 and the drive of the impact rotor for Forge.
    The speed of the Antriebsriemenscr.eibe 2 is detected by a first speed sensor 6, the speed of
    Output pulley 3 from a second speed sensor. 7
    The measured values of the rotational speed sensors 6, 7 are fed to a control device 8.
    Based on the measured rotational speeds, the control device 8 determines the ratio of the rotational speed of the driven pulley 3 to the rotational speed of the drive pulley 2. With complete frictional connection, this ratio corresponds to the transmission ratio vcn output pulley 3 to drive pulley 2. U.a. Depending on the feed material to be crushed, however, a certain amount of slippage of the drive belt 1 may be permissible or even desired, so that a speed ratio deviating from the transfer ratio is accepted. In addition, some slippage can prevent a sudden stalling of the drive motor 11 when the breaker device obstructs me.
    In practice, of course, only speed ratios make sense, which make up a relatively high proportion of the transmission ratio of the pulleys 2, 3, such as at least 90%, preferably at least 97% of the transmission ratio of the pulleys 2, 3. This
    Drehzahiverhälunis can be specified and defines the crazy state. The control unit 3 controls the hydraulic cylinder 5 so that the measured speed ratio corresponds to the predetermined speed ratio. 1*.
    In particular, the starting of the breaker device is controlled in this way via the control device 8. Fig. 4 shows a detailed view of the dashed line in Fig. 1 area C, the tension pulley 4, although the drive belt 1 touched but not pressed against the drive belt 1 so that it is not tensioned. Scattdessen the drive belt 1 is on guide plates 15 which surround the pulleys 2, 3 partially in a region outside the drive belt 1. Likewise, an upper run 19 of the drive belt rests on a guide plate 13. This becomes particularly clear in the section through the drive belt 1 and the guide plate 18 along the line B-B in FIG. 4, shown in FIG. 5, the arrows indicating the viewing direction.
    The state shown in Fig. 4 corresponds to a disengaged state, In this state, for example, maintenance work can be carried out easily, in which the drive motor 11 has to run. If in this case the impact rotor must be locked, the impact rotor can be blocked by means of a known and not shown detent.
    Between the pulleys 2, 3 of the drive belt 1 is substantially rectilinear, with a strong horizontal component in the illustrated embodiment.
    Accordingly, the drive belt 1 has an upper 19 and a lower strand 13. In the region of the upper run 19 of the drive belt 1 is guided by a straight guide plate 18 and _iegt the drive belt 1 in the relaxed state on the guide plate 18, see. Fig. 5. In the region of the lower run 13, the clamping plate 4 can attack and press against the drive belt 1 to tension this. l · *.
    Fig. 2 shows the same section C as Fig. 4, but never the drive belt 1 in the tensioned state. Accordingly, the clamping plate 4 has been moved by means of the hydraulic cylinder 5 on the drive belt i to and pushes against it. As a result, the drive belt 1 is tensioned and lifts off the Führungsbxechen 15, 18 from. Fig. 3 illustrates the lifting of the tensioned drive belt 1 from the guide plate 18 with reference to the section along the line A-A in Fig. 2, wherein the arrows indicate the viewing direction. This corresponds to a coupled

    When Hinkuppeln or when. Starting the crusher device verifies the control unit 8, whether after a certain, pre-commandable start-up time tA, the speeds of the antress pulley 2 and driven pulley 3 are actually in a predetermined ratio. If the desired speed ratio is not reached after the startup time tA, then the control device 8 switches off the drive motor 11 in order to avoid damage to the drive belt 1.
    In addition, the material supply 10 can be controlled via the control unit 3. In the event of an overload, where too much feed material has been supplied to the impact rotor and the speed ratio of the belt slides 2, 3 has dropped significantly below the state defining the approached state, the control unit 8 can throttle or completely stop the material supply 10, so that after processing the too large amount of feed material again the desired speed ratio of the pulleys 2, 3 einstelier. can. Of course, it is also conceivable in this case that the control unit 8, the drive motor 11 switches off when the desired speed ratio of the pulleys 2, 3 has not adjusted despite throttling or stop the material supply 10 after a certain time again.

    The minced feed material becomes, as in Fic. 1 is recognizable, discharged via a Materialaustrageband 16. In addition, a crawler 14 is shown in Fig. 1, by means of which the crusher is movable or can change its position by itself.
