Definitions

  • the invention relates to an impact crusher according to the preamble of patent claim 1.
  • Impact crushers are commonly known as crushers.
  • the feed material freed from the fine material by a sieve or grate passes between blow bars of a rotatingly driven rotor and baffle plates or so-called monoblocks and is crushed between them to a predetermined grain.
  • Known impact crushers or impact mills are normally designed for certain types of rock to be crushed, for example hard rock, medium-hard rock, etc. In addition, they are designed for certain degrees of comminution, which, however, are determined by Ver position of the monoblocks can be changed within limits. If the known impact mills are used in quarries, they will find a certain rock and can be set up accordingly. However, crushers are increasingly being used in recycling, for example of building materials such as rubble, road construction or the like. Such a material comes in very different grain sizes and hardness. It is not possible to provide the appropriate impact crusher for this. Impact mills are very complex devices that, if possible, must be used in continuous operation in order to work cost-effectively.
  • the object of the invention is to make a conventional impact mill convertible into a crusher for soft waste or the like by means of additional components and simple assembly steps.
  • the invention takes advantage of the fact that conventional impact crushers consist of two housing sections which can be pivoted away from one another.
  • the pivotability of a housing section serves to provide access to the rotor, in particular in the case of so-called stoppers. Without such a measure, it is hardly possible to loosen or remove a jammed rock.
  • an impact crusher can work even when the housing is in the opened state and care is taken that a lateral boundary is provided which prevents the material which has now been input from above from falling out laterally.
  • a conventional impact crusher into a shredding device for soft waste, essentially only three components are necessary, namely the side boundary plates and a modified mono block.
  • the monoblock mounted on it lies relatively far from the rotor, so that material thrown in from above would fall through the gap between the monoblock and the rotor without being crushed.
  • the lower monoblock in the opened state would form an excessively large gap with the rotor.
  • another monoblock is therefore installed, the lower end of which comes close to the motor.
  • the monoblock which has a suitable slope, which ensures that the material to be shredded automatically slides down, is preferably pivotably articulated in the upper region and is preferably connected in the lower region to an adjusting cylinder, via which the pivoting position of the monoblock can be changed.
  • the adjusting cylinder which is articulated to the further monoblock, can be connected to a vibration device with which the material to be shredded is set into more or less strong vibrations. These cause the soil and sand to be shaken off, which can otherwise lead to premature wear of the shredding tools.
  • the plate In order to prevent material to be shredded from escaping through the usual filling opening, it is expedient according to one embodiment of the invention to cover the open side of the first housing section facing the pivoted-down second housing section with a plate or the like.
  • This plate facilitates the sliding down of material to be shredded, which is inserted between the folded-down housing halves.
  • said plate can be designed as a press die which can be moved in the direction of the second housing section and away from it by means of at least one adjusting cylinder. With the help of such a press ram, the material to be shredded located between this and the monoblock can be compressed to a certain extent in order to facilitate slipping or to prevent jamming in the funnel above the rotor.
  • the cross section of the hopper can be increased considerably, so that relatively large objects, such as tree stumps, can be fed.
  • the motor of an impact crusher preferably an electric motor, is designed for a certain crusher output, the aim being to choose the size of the motor so that the operating conditions that usually occur are without damage can be mastered for the engine. If very large pieces to be broken are given up, for example of a consistency that is not as hard as tree stumps or the like, the motor may be required to perform quite well. This is particularly the case if knife tools are used instead of the usual blow bars, which will be discussed further below. There is a risk that the motor will be overloaded and damaged. Such pieces can therefore not be processed with the impact crusher.
  • the invention is therefore based on the further object of improving an impact mill of the type mentioned at the outset in such a way that overloading of the crusher motor due to components which are difficult to break is avoided and these components can nevertheless be broken.
  • At least one clamping element is adjustably mounted above the rotor.
  • the clamping element can be formed by the further monoblock or, according to another embodiment of the invention, by a press ram which is adjustably mounted on the other housing part with respect to the monoblock by means of an adjusting cylinder.
  • the adjusting device for the clamping element can adjust the clamping element above the rotor into a clamping position that reduces the feed cross section and into a retracted rest position.
  • a current measuring device which is connected to a control device, is assigned to the supply circuit for the drive motor of the rotor.
  • the control device outputs an actuating signal to the adjusting device for adjusting the clamping element from the rest position to the clamping position when the current exceeds a predetermined value. An adjustment in the opposite direction takes place when the current falls below a predetermined value again.
  • the invention is based on the knowledge that the supply current for the rotor is an indicator of the load on the motor. With the help of the current measuring device, the overload can thus be easily detected.
  • Overload measurement is generally known for electric motors. In the invention, however, is not the over load, but a current value that is below the value at which the motor is switched off in the event of overload protection.
  • the rotor should continue to rotate. The current measurement signal only serves to actuate the clamping element so that the piece to be broken is clamped in the funnel above the rotor and can therefore not slide further. The rotor continues to turn and can further process and shred the facing section of the piece to be broken. It gradually returns to normal speed, which is reflected in the reduction in the measured current.
  • the clamping element can be moved back into the rest position.
  • the usual breaking operation can therefore be continued.
  • the described process can be repeated several times.
  • the piece to be broken is not only held in place when the clamping element is moved into the clamping position, but is possibly pushed up a little by: using the assigned area of the monoblock as a ramp, is pushed along the monoblock.
  • the clamping position of the clamping element is not a fixed position, but depends on the size of the piece to be broken and clamped. It is only necessary that the adjusting device acts on the clamping element with a predetermined force.
  • blow bars which in combination with the monoblock cause the crushing effect.
  • Blow bars are not suitable for softer goods. Blow bars would only squeeze the goods and would not be able to shred them into individual pieces. Therefore, an embodiment of the invention provides that knife tools can optionally be attached to the rotor.
  • the knife tools are preferably designed so that they can be used on the rotor instead of the blow bars without special conversion measures.
  • bar-like knife holders can be provided, on which the knife tools can be releasably attached.
  • the cutter bars are attached to the rotor instead of the blow bars and in turn serve to attach individual cutter tools, which are preferably arranged at intervals from one another are.
  • This design of the knife tools also has the advantage that individual worn or destroyed knives can be replaced. Since, as mentioned, no continuous knife edge has to be provided, it is advantageous if the lower edge of the monoblock facing the rotor has recesses corresponding to the knife tools that pass through the knife tools when the rotor is rotating. The monoblock therefore extends further to the rotor between the knife tools. Knife tools and monoblock are therefore somewhat interlocked.
  • a pressing device can be provided according to one embodiment of the invention, which is assigned to the upper filling opening. It can be formed, for example, by a flap which is actuated by a force element, for example a hydraulic cylinder.
  • the pivot axis for the second housing section lies at a certain distance from the contact surface of the impact crusher.
  • the maximum opening width caused in this way is sufficient to eliminate stoppers. If, however, according to one embodiment of the invention, the pivot axis is immediately close to the footprint is arranged, a larger "mouth width" is achieved with the housing opened.
  • the impact crusher shown in FIG. 1 has a housing 10 with a first housing section 11 and a second housing section 12.
  • the first housing section 11 has a lying frame 14 with a contact surface 15, in which a rotor 16 is rotatably mounted, which is supported by a Electric motor, not shown, is driven.
  • the rotor carries blow bars 17 at a circumferential distance of 90 °, which are attached in suitable clamping devices 18.
  • the upright section 18a of the first housing section 11 has a feed mouth 19.
  • the second housing section 12 is mounted at 20 on the left upper end of the frame section 14 so as to be pivotable about a horizontal axis. 1 shows the housing section 12 in the opened position, as is normally assumed when access to the rotor 16 is required to remove the stopper.
  • the second housing section 12 supports, in a manner known per se, dashed monoblocks 21 and 22, which are pivotally mounted at upper pivot points (not specified in any more detail) and are articulated at a distance from them on adjusting rods of adjusting cylinders 23 and 24, respectively.
  • the monoblocks 21, 22 are in one set when the impact crusher shown is operated with the housing sections 11, 12 folded together in a conventional manner, the material to be shredded, for example rock material, being fed into the mouth 19 in the direction of arrow 25.
  • the monoblock 22 is removed, and a monoblock 26 (shown in solid lines) takes its place, which is pivotally mounted at 27 in the housing section 12 and on which the adjusting rod 28 is at 28 Adjusting cylinder 29 is articulated.
  • the monoblock 21 which is shown in two different positions in FIG. 1, can assume the most withdrawn position or can also be removed.
  • Correspondingly shaped sheets are inserted and fastened laterally between the housing sections 11, 12, one of which can be seen at 30.
  • the sheets 30 connect the housing sections 11, 12 to one another and hold them in the unfolded position. At the same time, they delimit a filling funnel which is open at the top and whose filling opening is labeled 31.
  • a sheet metal plate 32 is connected to the first housing section 11 on the side opposite the monoblock 26 and blocks the passage to the mouth 19.
  • the impact crusher is suitable for picking up more or less soft material to be shredded, the pieces of which can take up a relatively large volume.
  • blow bars 17 are attached to the rotor 16, as mentioned. They are not particularly suitable for shredding softer goods. It is therefore expedient to replace the blow bars 17 with knife tools.
  • 5 shows a knife bar 40 which has mounting projections 41 in its upper side for correspondingly shaped knives.
  • the cutter bar 40 is received by the clamping devices 18 instead of the blow bars 17.
  • a corresponding knife 42 is shown in FIG. 4. Viewed from the front, it has an arcuate contour, the arc being formed by a knife edge or knife edge 43, while the surface 44 located in between is recessed, as can be seen in dashed lines in the left-hand illustration of FIG. 4.
  • the plane in which the knife edge 43 lies is inclined obliquely forward radially outward.
  • the underside of the knife 42 is designed so that the knife 42 can be conveniently attached to the mounting projections 41, for example with the aid of a suitable screw connection.
  • Fig. 3 several such knives 42 are indicated schematically, as they are arranged along a knife bar.
  • the lower region of the monoblock 26 is also indicated in FIG. 3. It can be seen that the lower edge is shaped in accordance with the cutter bar 40 or the cutters 42, and thus has recesses 45 through which the cutters 42 pass when the rotor 16 rotates.
  • the adjusting cylinder 29 By actuating the adjusting cylinder 29, the distance between the monoblock 26 and the cutter bar or the rotor can be changed and the size of the material to be shredded can thus be determined.
  • the articulation point 27 of the monoblock 26 can also be connected to an externally attached adjusting cylinder in order to adjust the monoblock 26 as desired in one plane. In this case, however, the monoblock 21 must be removed.
  • Fig. 2 shows a similar representation as Fig. 1, so that the same parts are provided with the same reference numerals.
  • the monoblocks 21, 22, which are provided for the normal operation of the impact crusher, are preferably removed, in particular the monoblock 21, by a relatively long monoblock 50 space whose upper end extends close to the upper end of the opened housing section 12 and is pivotally mounted at 51 at a distance from it. Near the lower end, the adjusting rod of a hydraulic cylinder 52 articulates. It goes without saying that a hydraulic cylinder can also act on the pivot point 51.
  • the lower end of the monoblock 50 can, for example, be the same as that of the monoblock 26 according to FIG. 1 if the baffle strips 17 are replaced by knife tools shown in FIGS. 3 and 4.
  • the left open end of the upright section 18 of the first housing section 11 is covered by a plate-shaped press ram 55 which is suspended from the adjusting rods of two adjusting cylinders 56, 57.
  • the adjusting cylinders 56, 57 are held on a plate 58, which is shown schematically and is fastened in the first housing section 11 with the aid of suitable precautions.
  • the punch 55 can be adjusted in the direction of the double arrow 60 in order to exert a corresponding pressing pressure on the material to be shredded which is filled in from above.
  • the rotor 16 is driven by an electric motor 60, which is connected to an AC voltage source 62 via a line 61.
  • the line 61 is associated with a current transformer 63 which is connected to a control device 64.
  • the control device 64 controls the hydraulic cylinders 56, 57 for the press ram 55 via a corresponding line 65.
  • the control member 64 controls the cylinders 56, 57 so that the ram 55 in Move towards the monoblock 50.
  • a piece to be broken located above the rotor 16 is thereby clamped between the punch 55 and the monoblock 50. It can no longer slide and the rotor 16 or its blow bars 17 can gradually freeze, and the rotor can thus return to its normal speed.
