Description

TECHNICAL FIELD

[0001] The invention relates to a crushing device for crushing mineral material and the like, the crushing device having a crushing unit, the crushing unit having a crushing chamber, wherein a comminution device is accommodated in the crushing chamber, in particular movably, preferably rotatably or in a gyratory manner, wherein the comminution device carries or has at least one comminution tool, in particular a crushing tool, wherein the crushing chamber is delimited by at least one crushing chamber boundary, wherein the crushing chamber boundary has an inner surface facing the crushing chamber and an outer surface facing away from the crushing chamber, and wherein the crushing chamber boundary has an inspection opening.

[0002] For example, the crushing device according to the invention can be designed with a rotor as a comminution device, which is held rotatably in the crushing chamber. Thus, such a crushing device can be an impact crusher, a cone crusher or a gyratory crusher. Alternatively, it can also be a comminution device with a crushing body which is arranged rotatably in the crushing chamber. Such a crushing device can be, for example, a jaw crusher.

[0003] For example, the crushing tool can be a replaceable tool which is interchangeably connected to the comminution tool. In particular, the crushing tool can be an impact bar, an impact rocker, a crusher spindle, a crusher roll or a crushing jaw.

[0004] In the invention, the crushing tool does not necessarily have to be part of a movable component of the comminution tool, for example a rotor or a gyratory crushing body. Rather, in the invention, the crushing tool can be a component which is arranged at least partially in the crushing chamber, for example an impact rocker or a crushing chamber lining, in particular also part of the crushing chamber boundary. BACKGROUND

[0005] The crushing chamber of a general crushing device, in particular a rock crusher, is very difficult to access due to the nature of the system. The safety measures required to access the crushing chamber make accessibility even more difficult. Regularly checking the wear parts in the crushing chamber is therefore very time-consuming. For this reason, a sensor-based wear measurement offers great advantages in terms of operator safety and machine downtime in addition to purely wear measurement. In addition to purely wear measurement, this enables the operator to plan the adjustment of the crushing gap and the stocking and installation of the wear parts as wear progresses, such a system can detect damage in time and prevent major machine damage. Furthermore, a sensor-based wear measurement offers significant advantages in terms of measurement accuracy compared to the visual assessment by the machine operator which is common today.

[0006] A known solution from existing technology involves wearing parts of the crushing tool made of cast material. The measuring system of the detection device is directly built into the cast part. However, this is only feasible at a high cost. Furthermore, the detection device must be replaced when the wearing parts are replaced, requiring a large number of components.

[0007] Methods for using ultrasound to determine the layer thickness of worn parts are also known (see DE 2357 432 B2). Ultrasonic sensors used to determine coating thickness typically employ a sensor head directly attached to the worn part. Otherwise, sound waves would be reflected or refracted when the medium changes (e.g., from air to steel). Such a sensor arrangement is also impractical. Summary of the Invention

[0008] The present invention solves the problem of providing a crushing device of the type mentioned at the beginning, which makes safe and reliable wear detection possible.

[0009] The solution to this problem is to provide a detection device held by a mounting member for determining the wear condition of at least one worn component (particularly a crushing tool), the detection device being movable between a parking position and a detection position by means of an actuator through an inspection opening, wherein the detection device is at least partially arranged inside the crushing chamber in the detection position and outside the crushing chamber in the parking position.

[0010] Therefore, the detection device is no longer assigned to the wear component but can be used separately from it. In the operating position, the detection device is available inside the crushing chamber and can detect the condition of the wear component. Once the condition of the wear component is detected, the actuator moves the detection device through the inspection opening to a protected area behind the outer surface of the crushing chamber boundary. Preferably, the crushing device can be stopped briefly to determine the wear of the wear component, and then the detection device can be moved into the crushing chamber. This allows for efficient and safe detection of the wear component condition. It effectively eliminates the risk of damage to the detection device due to the effects of crushed material and / or dust.

[0011] Specifically, the detection device can be an optical measuring device, such as a measuring device with a laser scanner or camera, preferably a stereo camera (especially a 3D camera) or a 2D camera. It is also conceivable that the detection device has one or more laser distance sensors or TOF cameras. Electromagnetic distance measurement methods or capacitance measurement methods, such as radar sensors or eddy current sensors, are also conceivable.

[0012] According to the invention, the wear component can in particular be a crushing device or part of a crushing device. It is conceivable that the wear component according to the invention is a crushing tool or part of a crushing tool, such as a shredder. It is also conceivable that the wear component according to the invention is a crushing chamber liner or part of a crushing chamber liner. In the invention, the wear component can also be any other component that comes into contact with the material to be crushed or shredded in the crushing chamber.

[0013] According to a preferred design variation of the invention, the mounting element is specified to translate, in particular, linearly, between the detection position and the parking position. Due to this translation, and especially linear movement, the inspection opening can be designed to have a relatively small opening cross-section. Furthermore, this allows for a movement that can move the mounting element sufficiently far into the crushing chamber using a simple sequence of movements and with minimal space requirements.

[0014] Preferably, the direction of linear movement of the mounting component can be specified to be inclined relative to the inner or outer surface of the crushing chamber boundary within a range of 20° to 70°, preferably from 30° to 60°, and particularly preferably from 40° to 50°. In this way, a large optical detection area can be achieved for the detection device, which is simultaneously adjacent to the inner surface of the crushing chamber boundary.

[0015] If the first movement specifies the movement of the mounting component from its parking position to an intermediate position, wherein the first movement includes a rotational movement of the mounting component, and the second movement specifies the movement of the mounting component from the intermediate position to an inspection position, wherein the mounting component moves in a straight line through an inspection opening during the second movement, a particularly space-saving design can be achieved.

[0016] If the mounting component has or supports a housing, wherein the housing has the mounting component and the detection device is at least partially housed within the mounting component, the detection device can be effectively protected from mechanical impacts. Particularly preferably, the housing has an opening through which the detection device detects the wear condition of worn parts, particularly the wear condition of the crushing tool, in a detection position. Preferably, the opening points downwards in the detection position to prevent crushed material falling from inside the crushing chamber from damaging the detection device.

[0017] If the mounting is specified as part of the actuator's actuation unit, preferably wherein the actuator has a cylinder in which a piston is movably guided, and the mounting is specified to be connected to the piston or cylinder, a simple and robust design can be achieved. In this case, especially if the mounting is specified to be integrally connected to the piston or cylinder, a smaller number of parts can be achieved.

[0018] Possible variations of the invention may include a mounting component that carries or has a closed arrangement structure, and this closed arrangement structure seals the inspection opening in the parking position. Preferably, the closed arrangement structure is a wear member that is interchangeably connected to the mounting component. Therefore, during crushing operation, i.e., when the inspection device is in the parking position, the closed arrangement structure prevents crushed material from entering the area on the outer surface of the boundary wall. When the mounting component moves from the parking position to the inspection position, the closed arrangement structure can be separated from the crushing chamber boundary, for example, if it is part of the mounting component or a head component connected to the mounting component.

[0019] A possible variation of the invention could be as follows: a retaining device is arranged in the region of the outer surface of the crushing chamber boundary, the retaining device holding a bearing section spaced apart from the outer surface of the crushing chamber boundary, wherein the mounting member is rotatably connected to the bearing section by means of a guide member, such that the mounting member can be rotated from its resting position to an intermediate position, and the actuator can move the detection device from the intermediate position to the detection position.

[0020] A robust design can be achieved if the retaining device has two bearing sections arranged spaced apart from each other, a mounting member is held between the two bearing sections, and the mounting member is movably connected (preferably rotatably connected) to the two bearing sections.

[0021] A possible variation of the invention could be as follows: the bearing section has a connecting rod with a linear guide section that merges into a locking section, and the mounting member is movably guided in a translational manner on the linear guide section by means of a guide member. This means that the linear guide section can first move the mounting member to an intermediate position and there secure it in the locking section. The movable housing can then be translated to bring the detection device to the detection position. This makes the design particularly space-efficient. For example, the mounting member can then be held in a parking position immediately adjacent to the outer surface of the crushing chamber boundary.

[0022] Alternatively or additionally, the retaining device may be provided with a guide, and the actuating unit carrying the detection device may be adjustablely guided on the guide in a translational, particularly linear, manner via the guide member. For this purpose, the actuating unit can be used to move the detection device into the detection position.

[0023] The crushing device according to the invention may include a transmission mechanism for moving the detection device between a detection position and a parking position. This transmission mechanism may be designed to suit structural conditions to ensure an appropriate sequence of movement of the detection device within a confined space.

[0024] Specifically, the transmission device can accelerate or decelerate the adjusting motion of the actuator to move the detection device.

[0025] A particularly simple transmission device can be designed as a flat transmission device. Preferably, and particularly, the actuator can be coupled to one arm of the toggle lever, the other arm of which can be rotatably connected to the connector via a joint, and the connector can be directly or indirectly connected to the mounting component. Preferably, the toggle lever is fixed in a stationary position at the boundary of the crushing chamber. Attached Figure Description

[0038] Figure 12 Showing the location in the detection positionFigure 11 The expression . Detailed Implementation

[0039] Figure 1 The material handling equipment 1 shown is in the form of a crusher, which has a material handling unit in the form of a crusher unit 10. The material handling equipment 1 is designed as a mobile material handling equipment 1, and therefore has a traveling unit 1.5. However, it is also conceivable that the material handling equipment 1 is a stationary material handling equipment 1.

[0040] The material handling equipment 1 has a chassis 1.1 that carries machine components or at least a portion of them. At its rear end, the chassis 1.1 may preferably have a cantilever 1.2. A material feed area is formed in the region of the cantilever 1.2.

[0041] The material feeding area may include a feeding hopper 2 and a material feeding device 9.

[0042] The feed hopper 2 may be formed at least partially by a hopper wall 2.1 extending in the longitudinal direction of the material handling equipment 1 and a rear wall 2.2 extending transversely to the longitudinal direction. The feed hopper 2 leads to the material feeding device 9.

[0043] As shown in this exemplary embodiment, the material feeding device 9 may include a conveyor chute that can be driven by a vibration driver. The feed hopper 2 may be used, for example, to feed the material to be crushed into the material handling equipment 1 and onto the conveyor chute using a wheel loader.

[0044] As shown in the figure, preferably, the material to be crushed enters the area of ​​the screening unit 3 from the conveyor chute. This screening unit 3 can also be referred to as a pre-screening arrangement. At least one screen plate 3.1, 3.2 is disposed in the area of ​​the screening unit 3. In this exemplary embodiment, two screen plates 3.1, 3.2 are used. A system configuration without using a pre-screening arrangement is also conceivable.

[0045] A portion of the material to be crushed is screened out at the upper sieve plate 3.1. This portion of the material already has a sufficient particle size to no longer require further crushing in the material handling equipment 1. In this respect, the screened portion of the material can be guided through the bypass channel 3.5 through the crusher unit 10.

[0046] If a second screen plate 3.2 is used in screening unit 3, a finer particle fraction can be screened from the fraction accumulated below screen plate 3.1. This fine particle fraction can be guided to a side discharge conveyor 3.4 below screen plate 3.2. The fine particle fraction is then diverted from the side discharge conveyor 3.4 and conveyed to a rock pile 7.2 located on the side of the machine.

[0047] likeFigure 1 As shown, the screening unit 3 can be a vibrating screen with a screen drive 3.3. The screen drive 3.3 causes the screen plate 3.1 and / or screen plate 3.2 to vibrate. Due to the inclined arrangement of the screen plates 3.1 and 3.2 and their combination with the vibration motion, the material on the screen plates 3.1 and 3.2 is transported toward the crusher unit 10 or toward the bypass channel 3.5.

[0048] like Figure 1 As shown, the material to be crushed from the screen plate 3.1 is conveyed to the crusher unit 10.

[0049] The crushing unit 10 can be, for example, in the form of an impact crushing unit, particularly a rotary impact crushing unit, a jaw crushing unit, a cone crushing unit, or a slewing crushing unit. The crushing unit 10 has a pulverizing device 11.

[0050] If a rotary impact crusher unit is used, such as Figure 1 As shown, for example, it has an impact rotor for a crushing device 11, which is driven by an internal combustion engine 12. Figure 1 In the image, the rotation axis 17 of the impact rotor is horizontal in the direction of image depth. The impact rotor is housed in the crushing chamber 16.1.

[0051] If a jaw crusher unit is used, the crushing device 11 has two opposing jaws that surround a converging crushing shaft between them, thereby forming a crushing gap. At least one jaw can be driven, for example, by an internal combustion engine 12 to crush the material to be crushed filling the converging crushing gap.

[0052] For example, a crushing tool 11.2 may be fitted around the outer periphery of the impact rotor, which is designed as an impact rod in this case. For example, a wall element may be arranged opposite the impact rotor, preferably in the form of an impact rocker 20. When the impact rotor rotates, the impact rod throws the material to be crushed outwards. In doing so, the material impacts the impact rocker 20 and is crushed due to high kinetic energy. When the material to be crushed has a sufficient particle size to allow the material particles to pass through the crushing gap 15 between the impact rocker 20 and the radially outer end of the impact rod, the crushed material exits the crusher unit 10 through the crusher outlet 16.

[0053] It is conceivable that in the area of ​​crusher outlet 16, the crushed material conveyed from crusher unit 10 is combined with the material conveyed from bypass channel 3.5 and transferred to belt conveyor 1.3. Belt conveyor 1.3 can be used to transport the material out of the working area of ​​crusher unit 10.

[0054] As shown in the figure, the belt conveyor 1.3 may include an annular circulating conveyor belt having a slack side 1.6 and a tension side 1.7. The slack side 1.6 is used to capture and transport crushed material falling from the crusher outlet 16 of the crusher unit 10. At the belt end, deflector rollers 1.4 may be used to deflect the conveyor belt from the slack side 1.6 to the tension side 1.7 and vice versa. Guides, particularly support rollers, may be arranged in the area between the deflector rollers 1.4 to change the conveying direction of the conveyor belt in order to shape and / or support the conveyor belt in a certain way.

[0055] The belt conveyor 1.3 has a belt driver that can be used to drive the belt conveyor 1.3. The belt driver may preferably be located at the discharge end 1.9 of the belt conveyor 1.3 or in the area of ​​the discharge end 1.9.

[0056] The belt conveyor 1.3 can be connected to a control device via a control line, for example, by means of a belt driver.

[0057] One or more additional belt conveyors 6 and / or return conveyors 8 may be used, which in principle have the same design as belt conveyor 1.3. In this regard, reference may be made to the above description.

[0058] Magnet 1.8, particularly an electromagnet, can be positioned above the relaxation side 1.6 in the area between the feed end and the discharge end 1.9. Magnet 1.8 can be used to lift iron portions from the broken material and remove them from the conveying area of ​​the belt conveyor 1.3.

[0059] The re-screening device 5 can be located downstream of the belt conveyor 1.3. The crusher unit 5 has a screening housing 5.1 in which at least one screen plate 5.2 is installed. A housing base 5.3 is formed below the screen plate 5.2, which serves as a collection space for the material screened at the screen plate 5.2.

[0060] An opening in the lower housing portion 5.3 establishes a spatial connection to another belt conveyor 6. Here, the other belt conveyor 6 forms its feed area 6.1, in which the screened material in feed area 6.1 is guided onto the slack side of the other belt conveyor 6. The other belt conveyor 6 transports the screened material toward its discharge end 6.2. From there, the screened material is transferred to the rock pile 7.1.

[0061] Material not screened at screen plate 5.2 of the re-screening device 5 is conveyed from screen plate 5.2 to branch belt 5.4. Branch belt 5.4 can also be designed as a belt conveyor, i.e., refer to the explanation given above regarding belt conveyors 1.3. Figure 1 In the image, the transport direction of branch 5.4 extends in the direction of image depth.

[0062] At its discharge end, branch belt 5.4 transfers unscreened material (also known as oversized material) to the feed area 8.1 of return conveyor 8. Return conveyor 8 can be a belt conveyor that transports oversized material toward feed hopper 2. At its discharge end 8.2, return conveyor 8 transfers the oversized material back into the material stream, specifically to the material feed area. Thus, the oversized material can be returned to crusher unit 10 and crushed to the desired particle size.

[0063] Figure 2 A crushing device 11 with its crushing tools 11.2 is shown. These crushing tools are interchangeably held on the rotor of the crushing device 11. As shown in the diagram, the crushing device 11 is arranged in a crushing chamber 30. The crushing chamber 30 is at least partially enclosed and isolated from the surrounding environment by a crushing chamber boundary 31.

[0064] Figure 2 Only a portion of the crushing chamber boundary 31 is shown as an example. As shown in this representation, the crushing chamber boundary 31 may be part of a wall having an inner surface 31.2 facing the crushing chamber 30 and an outer surface 31.1 facing away from the crushing chamber 30. The crushing chamber boundary 31 has an inspection opening 32. The inspection opening 32 may be formed by a hole that is either excluded from or recessed into the crushing chamber boundary 31.

[0065] In this exemplary embodiment, the inspection opening 32 has the form of a rectangular hole, which is defined by opposing horizontal edge segments and opposing vertical edge segments.

[0066] As shown in the figure, a monitoring device with a detection device 50 is arranged in the area of ​​the boundary 31 of the crushing chamber. Figure 2 The detection device 50 is shown in the detection position. In this detection position, the detection device 50 is at least partially arranged in the crushing chamber 30. The detection device 50 can then detect the wear condition of at least one crushing tool 11.2 or any other wear component in the crushing chamber 30.

[0067] Figure 3 The detection device 50 is shown in a parking position. In this parking position, the detection device 50 is removed from the crushing chamber 30 and remains in the area behind the outer surface 31.1 of the crushing chamber boundary 31.

[0068] The detection device 50 can move between the parking position and the detection position, and in particular, it can move translationally, preferably linearly.

[0069] Figure 3Another design variation of the invention is shown. As shown in this embodiment, the inspection opening 32 may be formed by a hole in the crushing chamber boundary 31, which is preferably cut out of the crushing chamber boundary 31 with a circular cross-section. A guide element 33 may be arranged in the region of the inspection opening 32 for guiding the adjustment movement of the detection device 50 between the parking position and the detection position. Preferably, the guide element 33 is arranged around the inspection opening 32 and has, for example, at least one guide neck 33.1.

[0070] Figure 4 and Figure 5 The structure of the monitoring device is shown in more detail. As shown in these figures, the monitoring device has a mounting member 40 that carries the detection device 50. For this purpose, the mounting member 40 may have a housing 41 on or within which an actuation unit 44 is movably actuated. The actuation unit 44 may be located in... Figure 4 The parking locations shown are Figure 5 The movement occurs between the detection positions shown.

[0071] As shown in the figure, the adjustment movement of the actuation unit 44 is linear. Preferably, the angle between the movement direction of the actuation unit 44 and the plane formed by the crushing chamber boundary 31 is less than or equal to 90°. In this exemplary embodiment, the angle between the movement direction of the actuation unit 44 and the plane formed by the crushing chamber boundary 31 is selected in the range of 20° to 70°, preferably in the range of 40° to 60°. Figure 4 and Figure 5 In the specific exemplary embodiment shown, the angle is 45°.

[0072] The actuation unit 44 preferably moves from the parking position to the detection position in the upward actuation direction (i.e., against the direction of gravity).

[0073] The actuation unit 44 may have a head 45, which has a mounting member 47. A detection device 50 is housed in this mounting member 47. The detection device 50 may be an optical detection device, such as a camera. The mounting member 47 has an opening 47.1 that opens downwards against gravity, such as... Figure 5 As shown in the image.

[0074] Cable conduit 48 is incorporated into head 45 and serves to house the cable. This cable 48 can be used to electrically connect the detection device 50 to an evaluation circuit (not shown). Cable conduit 48 is arranged such that the cable can be protected in accordance with… Figure 5 The detection position is guided to the area behind the outer surface 31.1 of the crushing chamber boundary 31.

[0075] Figure 4 and Figure 5The guide neck 33.1 of the guide element 33 interacts with the anti-rotation lock 46 of the actuation unit 44. Specifically, the anti-rotation lock 46 may be designed as a groove that engages with the actuation unit 44 and extends in the actuation direction of the actuation unit 44. The guide neck 33.1 engages with this groove to prevent rotation of the actuation unit 44.

[0076] Preferably, housing 41 is part of actuator 80 (i.e., piston-cylinder unit). Housing 41 may form cylinder 82. Actuation medium (particularly hydraulic fluid) is held in chamber 42 of housing 41.

[0077] Preferably, the actuation unit 44 may be part of the actuator 80, and may specifically form the piston of the piston-cylinder unit.

[0078] If from Figure 4 Starting from the parking position shown, chamber 42 is pressurized with an actuating medium, causing actuation unit 44 to move through cylinder opening 43, so that detection device 50 is linearly guided through inspection opening 32 into crushing chamber 30. If the actuating medium is discharged from chamber 42, actuation unit 44 returns to chamber 42, which may also be supported by, for example, a spring (not shown).

[0079] Preferably, as shown, the actuation unit 44 includes or carries a closed arrangement structure 41.1. In this exemplary embodiment, the closed arrangement structure 41.1 is designed as a separate component interchangeably connected to the head 45 of the actuation unit 44. The locking arrangement structure 44.1 can be integrally designed with the head 45. Figure 4 In the parking position shown, the actuation unit 44.1 at least partially closes the inspection opening 32. In particular, the enclosed arrangement structure 41.1 may have a flat outer surface facing the crushing chamber 30, which is preferably aligned with the inner surface 31.2 of the crushing chamber boundary 31 in the parking position.

[0080] In the detection position, the enclosed arrangement structure 41.1 can be adjusted by the actuation unit 44. Preferably, the enclosed arrangement structure 44.1 is then held at a distance from the inner surface 31.2 of the crushing chamber boundary 31, such as... Figure 5 As shown in the image.

[0081] Figures 6 to 9 The figure illustrates another embodiment of the invention. The figure shows a retaining device 60 holding a monitoring device on the outer surface 31.1 of the crushing chamber boundary 31. The retaining device 60 has two bearing sections 62, which are preferably formed of plate-shaped support portions. Fastening sections 61 can be used to connect these plate-shaped support portions to the outer surface 31.1 of the crushing chamber boundary 31.

[0082] Preferably, the bearing segments 62 are arranged spaced apart from each other. An arrangement is maintained between two bearing segments 62 that is substantially equal to... Figures 3 to 5 The layout structure is as explained above. Therefore, the differences will be discussed below.

[0083] As shown in the figure, the actuation unit 44 has guide members 66 at opposite ends. These guide members 66 are linearly guided in the guides 63 of the holding device 60.

[0084] The retaining device 60 may also have at least one link 64 on which the mounting member 40 is movably guided. In this exemplary embodiment, the link 64 is disposed on each of the two bearing sections 62. The link 64 has a region forming a linear guide 64.1. The linear guide 64.1 is engaged in a locking section 64.2 facing away from the outer surface 31.1 of the crushing chamber boundary 31. Figure 6 As clearly shown, the locking section 64.2 can be designed as a lateral extension of the linear guide 64.1. The guide member 65 is used to guide the mounting member 40 in the two links 64.

[0085] In order to move the detection device 50 from Figure 6 The parking position shown has been moved to Figure 7 The detection position shown is first achieved by moving the mounting member 40 within the connecting rod 64 via the guide member 65 until the guide member 65 rests in the locking section 64.2. Simultaneously, the guide element 66 in the guide member 63 also moves slightly, causing the mounting member 40 to perform a rotational movement and enter the intermediate position. At the end of this adjustment movement, the head 45 of the actuation unit 44 is opposite the inspection opening 32, but remains within the area of ​​the outer surface 31.1 of the crushing chamber boundary 31.

[0086] Then, the actuation unit 44 can move linearly, causing the detection device 50 to move into the crushing chamber 30 through the inspection opening 32. The movement of the actuation unit 44 is linearly guided in the guide member 63 by the guide member 66.

[0087] Once the wear condition of the crushing tool 11.2 is determined, the actuation unit 44 can be linearly moved to the intermediate position through the inspection opening 32, and then the mounting part 40 can be moved to... Figure 6 The parking location is shown in the image.

[0088] It is conceivable that a closed arrangement structure 41.1 is also provided for closing the inspection opening 32. The closed arrangement structure 41.1 may have a closing portion that is displaceable and / or rotatable connected to the crushing chamber boundary 31.

[0089] Figure 8 and Figure 9Show Figure 6 and Figure 7 Cross-sectional views of various operating positions. As shown in these figures, the mounting 40 can again be formed as a housing 41 in the form of a cylinder 81 of the actuator 80. The actuating unit 44 can again be a piston rod 82, as... Figures 3 to 5 As shown in the image.

[0090] Figures 10 to 12 Another exemplary embodiment of the present invention is shown. Figure 10 The figure shows an actuator 80 provided in the form of a cylinder-piston unit. It has a cylinder 81. The piston is movably guided in the cylinder 81. The piston is coupled to a piston rod 82.

[0091] Actuator 80 can move mounting member 40 via transmission device 70. Mounting member 40 then carries detection device 50, for example... Figure 11 As shown in the image.

[0092] The transmission device 70 can preferably be designed as a flat transmission device. The transmission device 70 can have a toggle lever with two lever arms 73, 75 angled relative to each other. The toggle lever is mounted in place, preferably attached to the outer surface 31.1 of the crushing chamber boundary 31 via a retaining device 60. The retaining device 60 can have two bearing sections 62 arranged spaced apart from each other. The toggle lever is rotatably mounted between the two bearing sections 62. For this purpose, the toggle lever is rotatably connected to the retaining device 60 via a support bearing 74. Preferably, the actuator 80 is rotatably connected to the first lever arm 73 via a joint 76 via a piston rod 82. The second lever arm 63 is rotatably connected to the coupling 71 via the joint 72. The coupling 71 carries the mounting member 40 at its end opposite the joint 72. Preferably, the mounting member has a connecting mounting member 49 with a connecting joint 49.1 to which the coupling 71 is connected.

[0093] Figure 11 The figure shows that the connector mounting part 49 can be designed as a recess in the mounting part 40.

[0094] Mounting member 40 can be redesigned to form mounting member 47 on head 45. As in the exemplary embodiment described above, mounting member 45 can again have opening 47.1 through which detection device 50 can detect the wear condition of at least one crushing tool 11.2 in the detection position. Head 45 of actuation unit 44 again forms a closed arrangement structure 41.1, as shown, which can be integrally designed with head 45.

[0095] The actuation unit 44 is linearly movable within the linear guide 77, allowing it to move within the linear guide 77. Figure 11 The parking locations shown are Figure 12The detection positions shown move in a straight line. Preferably, the linear guide 77 is designed as a sleeve that protrudes in the region of the outer surface 31.1 of the crushing chamber boundary 31, and the mounting member 40 is accommodated in the sleeve.

[0096] If from Figure 11 Starting from the parking position shown, actuator 80 (whose cylinder 81 is fixed in a position opposite to the crushing chamber boundary 31) is actuated, and piston rod 82 extends from cylinder 81 and rotates the toggle lever. As a result of this rotational movement, coupling 71 also moves. As a result of this movement, actuator unit 44 shifts in linear guide 77 to move detection device 50 into crushing chamber 30. Once wear of at least one crushing tool 11.2 is detected, mounting member 40 returns in the opposite direction until detection device 50 rests in the... Figure 11 In the parking position shown. At the same time, the enclosed arrangement structure 41.1 of the actuation unit 44 also closes the inspection opening 32 (see...). Figure 11 ).

[0097] In the above explanation, the operating mode of the present invention is described with reference to the detection of wear condition of the crushing tool 11.2. However, the present invention is not limited thereto. Instead, the wear condition of any other wearing parts in the crushing chamber can be additionally or alternatively detected by the detection device 50.
