Description

[0001] The invention relates to a crushing device for crushing mineral material or the like, with a crushing unit having a crushing chamber, wherein a crushing device, in particular movable, preferably rotatable or pivotable, is received in the crushing chamber, wherein the crushing device carries or has at least one crushing tool, in particular a crushing tool, wherein the crushing chamber is limited by means of at least one crushing chamber boundary, wherein the crushing chamber boundary has an inner side facing the crushing chamber and an outer side facing away from the crushing chamber, and wherein the crushing chamber boundary has an inspection opening.

[0002] Crushing devices according to the invention can, for example, be designed such that they have a rotor as the crushing unit, which is rotatably mounted in the crushing chamber. Such a crushing device can therefore be, in particular, an impact crusher, a cone crusher, or a roller crusher. Alternatively, it can also be a crushing device in which the crushing unit has a crushing element pivotably arranged in the crushing chamber. Such crushing devices can, for example, be jaw crushers.

[0003] The crushing tool can be an interchangeable tool, for example, one that is connected to the shredding tool in an interchangeable manner. In particular, the crushing tool can be a striking bar, an impact arm, a crushing cone, a crushing roller, or a crushing jaw.

[0004] Within the scope of the invention, the crushing tool need not necessarily be part of the movable part (for example, the rotor or the pivoting crushing body) of the crushing tool. Rather, within the scope of the invention, the crushing tool can be a part that is arranged at least partially within the crushing chamber, for example, an impact arm or a crushing chamber lining, and in particular also a part of the crushing chamber boundary.

[0005] The crushing chamber of crushing equipment of this type, especially rock crushers, is inherently very difficult to access. The necessary safety measures for accessing the crushing chamber further complicate matters. The regularly required inspection of wear parts in the crushing chamber is therefore very time-consuming. Sensor-based wear measurements offer a significant advantage here, both in terms of operator safety and machine downtime. Beyond simply measuring wear, which allows the operator to adjust the crushing gap as wear progresses and to plan the inventory and installation of replacement parts, such a system enables the early detection of damage and the prevention of major machine failures.Furthermore, sensor-based wear measurement offers significant advantages in terms of measurement accuracy compared to the visual assessment by the machine operator that is common today.

[0006] Solutions are known in the prior art where wear parts of a comminution tool are made of a cast material. The measuring system of the detection device is integrated directly into the casting. This is only feasible with considerable effort when working with cast parts. Replacing the wear part also necessitates replacing the detection device, resulting in a high number of parts.

[0007] Methods that determine the layer thickness of wear parts using ultrasound are also known (see DE 2357432 B2). Ultrasonic sensors used for layer thickness determination typically employ a sensor head that is attached directly to the wear part. Otherwise, the sound waves would be reflected or refracted when the medium changes (e.g., from air to steel). Such a sensor arrangement is also impractical.

[0008] The object of the invention is to provide a breaking device of the type mentioned above, which enables reliable and safe wear detection.

[0009] This problem is solved by providing a detection device held by a carrier for determining the wear state of at least one wear part, in particular the crushing tool, and by making the detection device adjustable through the inspection opening by means of an actuator between a park position and a detection position, wherein the detection device is arranged at least partially in the crushing chamber in the detection position and is arranged outside the crushing chamber in the park position.

[0010] The detection device is therefore no longer physically attached to the wear part, but can be used separately. In its operating position, the detection device is available in the crushing chamber and can detect the condition of the wear part. Once the detection of the wear part's condition is complete, the actuator moves the detection device through the inspection opening into the protected area behind the outer edge of the crushing chamber. Preferably, to determine the wear of the wear part, the crushing unit can be briefly stopped and then the detection device retracted into the crushing chamber. This enables effective and safe detection of the wear part's condition. The risk of damage to the detection device from the crushed material and / or dust is virtually eliminated.

[0011] The detection device can be, in particular, an optical measuring device, for example, a measuring device comprising a laser scanner or a camera, preferably a stereo camera (especially a 3D camera) or a 2D camera. It is also conceivable that the detection device comprises one or more laser distance sensors or time-of-flight (TOF) cameras. Electromagnetic distance measurement methods, such as radar or eddy current sensors, or capacitive measurement methods are also conceivable.

[0012] According to the invention, the wear part can be, in particular, the comminution device or a part thereof. It is conceivable that, according to the invention, the wear part is a comminution tool or a part thereof, for example, the crushing tool. It is also conceivable that, according to the invention, the wear part is the crushing chamber lining or a part thereof. Within the scope of the invention, a wear part can also be any other component that comes into contact with the material to be comminuted or the comminutioned material in the crushing chamber.

[0013] According to a preferred embodiment of the invention, the carrier is adjustable, at least partially, translationally, and in particular linearly, between the detection position and the parking position. Due to this translational, and especially linear, movement, the inspection opening can be designed with a comparatively small cross-sectional area. Furthermore, this allows a movement to be generated with which the carrier can be moved sufficiently far into the crushing chamber with minimal space requirements and a simple movement sequence.

[0014] It is preferably provided that the direction of movement of the linear motion of the carrier is inclined relative to the planar inner or outer surface of the crushing chamber boundary in the range of 20° to 70°, preferably between 30° and 60°, and particularly preferably between 40° and 50°. In this way, a large optical detection area for the detection device can be created in close spatial proximity to the inner surface of the crushing chamber boundary.

[0015] A particularly space-saving design can be achieved if it is provided that the carrier is moved from its parked position to an intermediate position in a first movement, whereby this first movement includes a pivoting movement of the carrier, and that the carrier is moved from the intermediate position to the detection position in a second movement, whereby during the second movement the carrier is moved in a straight line through the inspection opening.

[0016] If the carrier is provided to have or carry a housing, wherein the housing has a receptacle in which the detection device is at least partially received, then the detection device can be effectively protected from mechanical influences. It is particularly preferred that the housing has an opening through which the detection device detects the wear condition of the wear part, especially the crushing tool, in the detection position. Preferably, the opening is directed downwards in the detection position to prevent damage to the detection device from material falling into the crushing chamber.

[0017] A simple and robust design is achieved when the carrier is part of an actuator element, preferably comprising a cylinder in which a piston is adjustable, and the carrier is coupled to the piston or cylinder. This results in a reduced number of parts, particularly if the carrier is integrally coupled to the piston or cylinder.

[0018] One possible embodiment of the invention is such that the carrier carries or has a locking mechanism, and that the locking mechanism closes the inspection opening in the parked position. Preferably, the locking mechanism is a wear part that is replaceably connected to the carrier. The locking mechanism thus prevents material being crushed from entering the area of ​​the outer boundary wall during crushing operation, i.e., when the detection device is in the parked position. The locking mechanism may be detached from the crushing chamber boundary when the carrier is moved from the parked position to the detection position, for example, if it is part of the carrier or connected to an end piece of the carrier.

[0019] One possible variant of the invention is such that a holding device is arranged in the area of ​​the outside of the crushing chamber boundary, which holds a bearing section at a distance from the outside of the crushing chamber boundary, wherein the carrier is pivotably coupled to the bearing section by means of a guide member, such that the carrier can be pivoted from its parked position to an intermediate position, and that the detection device can be adjusted from the intermediate position to the detection position by means of the actuator.

[0020] A robust design can be achieved if the holding device has two bearing sections spaced apart from each other, between which the support is held, and if the support is adjustable, preferably pivotably, connected to both bearing sections.

[0021] One possible embodiment of the invention is such that the bearing section or sections have a cam with a linear guide section that transitions into a locking section, and that the carrier is guided translationally along the linear guide section by means of a guide element. Thus, the carrier can first be moved into an intermediate position by means of the linear guide section and fixed there in the locking section. The housing can then be moved translationally to bring the detection device into the detection position. This allows for a particularly space-saving design. For example, the carrier can then be held in the parked position in close proximity to the outer edge of the crushing chamber boundary.

[0022] Additionally or alternatively, the holding device may also have a guide, and the actuator(s) supporting the detection device may be guided on the guide in a translationally, and in particular linearly, adjustable manner by means of a guide element. The actuator may then be used to move the detection device into the detection position.

[0023] A breaking device according to the invention can be configured such that a gearbox is provided by means of which the detection device can be adjusted between the detection position and the parked position. The gearbox can be designed to suit the structural conditions in order to ensure a suitable movement sequence of the detection device even in confined spaces.

[0024] In particular, the gearbox may increase or decrease the actuator's positioning movement in order to adjust the detection device.

[0025] A particularly simple gearbox can be designed as a planar gearbox. Preferably, the actuator can be coupled to a lever arm of a toggle lever, a further lever arm of the toggle lever can be pivotally connected to a coupling by means of a joint, and the coupling can be connected directly or indirectly to the support. Preferably, the toggle lever is fixed in position to the boundary of the crushing chamber.

[0026] The invention will be explained in more detail below with reference to exemplary embodiments illustrated in the drawings. The drawings show: Figure 1 shows a schematic representation and a side view of a material processing plant with a crushing unit; Figure 2 shows a schematic representation of a part of the crushing unit of the material processing plant according to Figure 1 In perspective view from the left, Figure 3 shows a schematic representation of a crushing chamber boundary of the crushing unit with a detection device, Figure 4 shows the arrangement according to Figure 3 in side view and in section, Figure 5 the representation according to Figure 4 in a modified operating position, Figure 6; another embodiment of a detection device for a crushing unit in a parked position, Figure 7; the arrangement according to Figure 6 in a capture position, Figure 8 the arrangement according to Figure 6 in vertical section, Figure 9 the arrangement according to Figure 7 in vertical section, Figure 10 another embodiment of a detection device in perspective view, Figure 11 the arrangement according to Figure 10in vertical section and in a park position and Figure 12 the representation according to Figure 11 in a recording position.

[0027] Figure 1 Figure 1 shows a material processing plant 1 in the form of a crushing plant with a material processing unit in the form of a crushing unit 10. The material processing plant 1 is designed as a mobile material processing plant 1 and therefore has chassis 1.5. However, it is also conceivable that the material processing plant 1 is a stationary material processing plant 1.

[0028] The material processing system 1 has a chassis 1.1 which supports the machine components or at least some of the machine components. At its rear end, the chassis 1.1 preferably has a boom 1.2. A material feed area is formed in the region of the boom 1.2.

[0029] The material feed area can include a feed hopper 2 and a material feed device 9.

[0030] The feed hopper 2 can be formed, at least partially, by hopper walls 2.1 extending in the direction of the longitudinal extent of the material processing plant 1 and a rear wall 2.2 extending transversely to the longitudinal extent. The feed hopper 2 leads to the material feeding device 9.

[0031] The material feeding device 9 can, as shown in the present embodiment, have a conveying trough that can be driven by a vibratory drive. Material to be crushed can be fed into the material processing plant 1 via the feed hopper 2, for example by means of a wheel loader, and fed onto the conveying trough.

[0032] As the drawing shows, the material to be shredded preferably enters the area of ​​a screening unit 3 from the conveying trough. This screening unit 3 can also be referred to as a pre-screening arrangement. At least one screen deck 3.1, 3.2 is arranged in the area of ​​the screening unit 3. In the present embodiment, two screen decks 3.1, 3.2 are used. A system configuration without a pre-screening arrangement is also conceivable.

[0033] At the upper screen deck 3.1, a sub-fraction is screened out of the material to be crushed. This sub-fraction already has a sufficient particle size that no longer needs to be crushed in the material processing plant 1. Therefore, this screened sub-fraction can be routed past the crushing unit 10 in a bypass channel 3.5.

[0034] If a second screen deck 3.2 is used in the screening unit 3, a further fine particle fraction can be screened from the sub-fraction that accumulates below screen deck 3.1. This fine particle fraction can be conveyed below screen deck 3.2 to a side discharge conveyor 3.4. From the side discharge conveyor 3.4, the fine particle fraction is discharged and conveyed to a stockpile 7.2 located to the side of the machine.

[0035] How Figure 1 As illustrated, the screening unit 3 can be a vibrating screen with a screen drive 3.3. The screen drive 3.3 sets the screen deck 3.1 and / or the screen deck 3.2 into vibratory motion. Due to the inclined arrangement of the screen decks 3.1, 3.2, and in conjunction with the vibratory motion, material is transported on the screen decks 3.1, 3.2 towards the crushing unit 10 or the bypass channel 3.5.

[0036] The material to be crushed, coming from screen deck 3.1, is fed to the crushing unit 10, as shown here. Figure 1 This can be seen.

[0037] The crushing unit 10 can be designed, for example, as an impact crusher, in particular as a rotary impact crusher, a jaw crusher, a cone crusher, or a roller crusher. The crushing unit 10 includes a comminution device 11.

[0038] It's like in Figure 1 If a rotary impact crushing unit is used, it has, for example, a crushing device 11 that includes an impact rotor driven by an internal combustion engine 12. Figure 1 The rotation axis 17 of the impact rotor runs horizontally in the direction of the image depth. The impact rotor is housed in a crushing chamber 16.1.

[0039] If a jaw crusher is used, the crushing device 11 has two opposing crushing jaws that enclose a converging crushing chute between them, leading to a crushing gap. At least one of the crushing jaws can be driven, for example by the combustion engine 12, to crush the material being crushed in the converging crushing gap.

[0040] The impact rotor can, for example, be equipped on its outer circumference with crushing tools 11.2, which in this case are designed as impact bars. Opposite the impact rotor, wall elements, preferably in the form of impact wings 20, can be arranged. When the impact rotor rotates, the material to be crushed is thrown outwards by the impact bars. This material then strikes the impact wings 20 and is crushed due to the high kinetic energy. If the material to be crushed has a sufficient particle size to allow the material particles to pass through a crushing gap 15 between the impact wings 20 and the radially outer ends of the impact bars, the crushed material leaves the crushing unit 10 via the crusher outlet 16.

[0041] It is conceivable that in the area of ​​the crusher outlet 16, the crushed material coming from the crushing unit 10 is combined with the material coming from the bypass channel 3.5 and conveyed onto a belt conveyor 1.3. The belt conveyor 1.3 can then be used to remove the material from the working area of ​​the crushing unit 10.

[0042] As the drawings show, the belt conveyor 1.3 can have an endlessly circulating conveyor belt with a loaded side 1.6 and an unloaded side 1.7. The loaded side 1.6 serves to collect and transport the crushed material that falls from the crusher outlet 16 of the crushing unit 10. At the belt ends, the conveyor belt can be deflected between the loaded side 1.6 and the unloaded side 1.7 by means of deflection rollers 1.4. In the area between the deflection rollers 1.4, guides, in particular support rollers, can be provided to change the conveying direction of the conveyor belt, to give the conveyor belt a specific shape, and / or to support the conveyor belt.

[0043] The belt conveyor 1.3 has a belt drive by means of which the belt conveyor 1.3 can be driven. The belt drive can preferably be arranged at the discharge end 1.9 or in the area of ​​the discharge end 1.9 of the belt conveyor 1.3.

[0044] The belt conveyor 1.3 can be connected to a control unit via a control line, for example by means of the belt drive.

[0045] One or more additional belt conveyors 6 and / or a return conveyor 8 may be used, which in principle have the same design as the belt conveyor 1.3. In this respect, reference can be made to the above explanations.

[0046] In the area between the feed end and the discharge end 1.9, a magnet 1.8, in particular an electromagnet, can be arranged above the load section 1.6. The magnet 1.8 can be used to lift iron parts from the broken material and move them out of the conveying area of ​​the belt conveyor 1.3.

[0047] In the transport direction after the belt conveyor 1.3, a secondary screening device 5 can be arranged. The secondary screening device 5 has a screen housing 5.1 in which at least one screen deck 5.2 is housed. Below the screen deck 5.2, a lower housing part 5.3 is formed, which serves as a collection chamber for the material screened out at the screen deck 5.2.

[0048] The lower housing section 5.3 creates a spatial connection to another belt conveyor 6 via an opening. Here, the second belt conveyor 6 forms its feed section 6.1, whereby the screened material in feed section 6.1 is directed onto the load side of the second belt conveyor 6. The second belt conveyor 6 conveys the screened material to its discharge end 6.2. From there, the screened material reaches a stockpile 7.1.

[0049] The material not screened at the screen deck 5.2 of the secondary screen 5 is conveyed from the screen deck 5.2 onto a conveyor belt 5.4. The conveyor belt 5.4 can also be designed as a belt conveyor, so reference can be made to the explanations given above regarding the belt conveyor 1.3. The conveyance direction of the conveyor belt 5.4 is in Figure 1 in the direction of the image depth.

[0050] At its discharge end, the conveyor belt 5.4 transfers the unscreened material, also known as oversize, to a feed area 8.1 of the return conveyor 8. The return conveyor 8, which can be designed as a belt conveyor, conveys the oversize towards the feed hopper 2. At its discharge end 8.2, the return conveyor 8 transfers the oversize back into the material flow, specifically into the material feed area. The oversize can then be fed back to the crushing unit 10 and crushed there to the desired particle size.

[0051] Figure 2 Figure 1 shows the shredding device 11 with its shredding tools 11.2. These are interchangeably mounted on the rotor of the shredding device 11. As the illustration shows, the shredding device 11 is arranged in the crushing chamber 30. The crushing chamber 30 is at least partially closed off from the surroundings by means of a crushing chamber boundary 31.

[0052] In Figure 2 Only an example of a crushing chamber boundary 31 is shown. As this illustration demonstrates, the crushing chamber boundary 31 can 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 can be formed by a cutout or recess in the crushing chamber boundary 31.

[0053] In the present embodiment, the inspection opening 32 is designed in the form of a rectangular opening, which is bounded by opposing horizontal and opposing vertical edge sections.

[0054] As the illustrations show, a monitoring device with a detection device 50 is arranged in the area of ​​the crushing chamber boundary 31. Figure 2 The detection device 50 is shown in a detection position. In this detection position, the detection device 50 is at least partially located in the crushing chamber 30. The detection device 50 can then detect the wear condition of at least one of the crushing tools 11.2 or of any other wear part in the crushing chamber 30.

[0055] In Figure 3The detection device 50 is shown in a parked position. In this parked position, the detection device 50 is moved out of the crushing chamber 30 and held in the area behind the outer surface 31 of the crushing chamber boundary 31.

[0056] The detection device 50 can be adjusted between the parking position and the detection position, in particular translationally, and especially preferably linearly.

[0057] Figure 3Figure 1 shows a further embodiment of the invention. As this illustration demonstrates, the inspection opening 32 can be formed by a breakthrough in the crushing chamber boundary 31, which is preferably a circular cutout from the crushing chamber boundary 31. A guide element 33 can be arranged in the area of ​​the inspection opening 32, which is used to guide the adjustment movement of the detection device 50 between the parked position and the detection position. Preferably, the guide element 33 is arranged around the inspection opening 32 and, for example, has at least one guide projection 33.1.

[0058] In the Figures 4 and 5The structure of the monitoring device is detailed below. As these illustrations show, the monitoring device has a carrier 40 that supports the detection device 50. For this purpose, the carrier 40 can have a housing 41 on or in which an actuator 44 is adjustable. The actuator 44 can be moved between the position shown in the diagram. Figure 4 shown parking position and the one in Figure 5 The shown detection position can be adjusted.

[0059] As the illustrations show, the adjustment movement of the actuator 44 is linear. Preferably, the angle of the direction of movement of the actuator 44 to the plane formed by the crushing chamber boundary 31 is less than or equal to 90°. In the present embodiment, the angle between the direction of movement of the actuator 44 and the plane formed by the crushing chamber boundary 31 is selected in the range between 20° and 70°, preferably in the range between 40° and 60°. In the Figures 4 and 5 In the specific embodiment shown, the angle is 45°.

[0060] The adjustment of the actuator 44 from the park position to the detection position preferably takes place in an upward direction, i.e. against the direction of gravity.

[0061] The actuator 44 may have a head 45 with a receptacle 47. The sensing device 50 is accommodated in this receptacle 47. The sensing device 50 may be an optical sensing device, for example, a camera. The receptacle 47 has an opening 47.1 that opens downwards against the direction of gravity. Figure 5 shows.

[0062] A cable channel 48 is integrated into the head 45, which serves to accommodate a cable. This cable 48 allows the detection device 50 to be electrically connected to an evaluation circuit (not shown). The cable channel 48 is arranged such that the cable is positioned according to the detection position. Figure 5 protected into the area behind the outer surface 31.1 of the crushing chamber boundary 31.

[0063] The Figures 4 and 5This shows that the guide element 33, with its guide projection 33.1, cooperates with an anti-rotation device 46 of the actuator 44. In particular, the anti-rotation device 46 may be designed as a groove machined into the actuator 44 and extending in the actuating direction of the actuator 44. The guide projection 33.1 engages in this groove to prevent rotation of the actuator 44.

[0064] Preferably, the housing 41 is part of an actuator 80, namely a piston-cylinder unit. The housing 41 may form a cylinder 82. A control medium, in particular a hydraulic fluid, is held in the chamber 42 of the housing 41.

[0065] Preferably, the actuating element 44 can be part of the actuator 80, and in particular form the piston of the piston-cylinder unit.

[0066] Starting from the in Figure 4When the chamber 42 is pressurized with the actuating medium in the parking position shown, the actuator 44 is moved through the cylinder opening 43 so that the detection device 50 is guided linearly through the inspection opening 32 into the crushing chamber 30. When the actuating medium is drained from the chamber 42, the actuator 44 retracts back into the chamber 42, which can also be assisted, for example, by a spring (not shown).

[0067] Preferably, as illustrated in the drawings, the actuator 44 has or carries a locking arrangement 41.1. In the present embodiment, the locking arrangement 41.1 is designed as a separate component that is interchangeably connected to the head 45 of the actuator 44. Alternatively, the locking arrangement 41.1 may be formed integrally with the head 45. In the Figure 4In the parking position shown, the actuator 44.1 at least partially closes the inspection opening 32. In particular, the closing arrangement 41.1 may have a flat outer surface facing the crushing chamber 30, which preferably aligns with the inner surface 31.2 of the crushing chamber boundary 31 in the parking position.

[0068] It is possible that in the detection position the locking arrangement 41.1 is adjusted by the actuator 44. Preferably, the locking arrangement 44.1 is then held at a distance from the inner side 31.2 of the crushing chamber boundary 31, as Figure 5 illustrated.

[0069] The Figures 6-9The figures illustrate a further embodiment of the invention. The illustrations show that the monitoring device is held on the outer surface 31.1 of the crushing chamber boundary 31 by means of a holding device 60. The holding device 60 has two bearing sections 62, which are preferably each formed by a plate-shaped support element. This plate-shaped support element can be connected to the outer surface 31.1 of the crushing chamber boundary 31 by means of a fastening section 61.

[0070] Preferably, the bearing sections 62 are arranged at a distance from each other. An arrangement is held between the two bearing sections 62, which corresponds to the arrangement shown in the Figures 3-5 This is essentially the same, so reference can be made to the preceding statements. Therefore, the differences will be discussed below.

[0071] As the illustrations show, the actuator 44 has guide elements 66 on opposite sides. These guide elements 66 are linearly guided in guides 63 of the holding device 60.

[0072] It is also possible that the holding device 60 has at least one cam 64 on which the support 40 is adjustably guided. In the present embodiment, a cam 64 is provided on each of the two bearing sections 62. The cam 64 has a section that forms a linear guide 64.1. This linear guide 64.1 transitions into a locking section 64.2 facing away from the outer side 31.1 of the crushing chamber boundary 31. How this Figure 6 As can be clearly seen, the locking section 64.2 can be designed as a lateral extension of the linear guide 64.1. The carrier 40 is guided in the two guideways 64 by guide elements 65.

[0073] For an adjustment of the recording device 50 from the in Figure 6shown parking position in the Figure 7 In the depicted detection position, the carrier 40 is first adjusted in the guide link 64 by means of the guide links 65 until the guide links 65 come to rest in the locking sections 64.2. Simultaneously, the guide links 66 also adjust slightly in the guides 63, causing the carrier 40 to pivot and enter an intermediate position. At the end of this adjustment movement, the head 45 of the actuator 44 is opposite the inspection opening 32, but is still located within the area of ​​the outer surface 31.1 of the crushing chamber boundary 31.

[0074] The actuator 44 can now be adjusted linearly so that the detection device 50 enters the crushing chamber 30 through the inspection opening 32. The actuator 44 is guided linearly in its movement by means of the guide elements 66 in the guides 63.

[0075] Once the wear condition of the shredding tools 11.2 has been determined, the actuator 44 can be moved linearly through the inspection opening 32 back into the intermediate position and then the carrier 40 can be moved into the Figure 6 The parking position shown will be brought into position.

[0076] It is conceivable that an additional locking arrangement 41.1 is provided, by means of which the inspection opening 32 is closed. This locking arrangement 41.1 can have a locking element that is slidably and / or pivotably connected to the crushing chamber boundary 31.

[0077] In the Figures 8 and 9 are the individual operating positions according to the Figures 6 and 7 shown in section. As these illustrations demonstrate, the carrier 40 can again form a housing 41 in the form of a cylinder 81 of an actuator 80. The actuating element 44 can again, as in the Figures 3-5 shown to be a piston rod 82.

[0078] The Figures 10-12show a further embodiment of the invention. Figure 10 Figure 80 illustrates that an actuator 80 is provided in the form of a cylinder-piston unit. This unit has a cylinder 81. A piston is adjustable within the cylinder 81. The piston is coupled to a piston rod 82.

[0079] The actuator 80 allows the carrier 40 to be adjusted via a gearbox 70. The carrier 40 in turn supports the detection device 50, as is the case, for example, Figure 11 shows.

[0080] The transmission 70 can preferably be designed as a planar transmission. It can be configured such that the transmission 70 has a toggle lever with two lever arms 73, 75 arranged at an angle to each other. The toggle lever is fixedly mounted, preferably by means of a holding device 60 on the outside 31.1 of the crushing chamber boundary 31. The holding device 60 can have two bearing sections 62, which are spaced apart from each other. The toggle lever is pivotably mounted between the two bearing sections 62. For this purpose, the toggle lever is pivotably connected to the holding device 60 by means of a support bearing 74. The actuator 80 is pivotably coupled to the first lever arm 73 via a joint 76, preferably by means of the piston rod 82. The second lever arm 63 is pivotably connected to a coupling 71 via a joint 72. The coupling 71 carries the support 40 at its end facing away from the joint 72.Preferably, the carrier has a coupling receptacle 49 with a coupling joint 49.1 to which the coupling 71 is connected.

[0081] Figure 11 illustrates that the coupling receptacle 49 can be designed as a recess in the carrier 40.

[0082] The carrier 40 can again be designed to form a receptacle 47 on a head 45. The receptacle 45 can again, as in the preceding embodiments, have an opening 47.1 through which the detection device 50, in the detection position, can detect the wear state of at least one shredding tool 11.2. The head 45 of the actuator 44 again forms a closing arrangement 41.1, which, as the figures show, can be formed integrally with the head 45.

[0083] The actuator 44 is guided in a linear guide 77 so that it can move linearly between the in Figure 11 shown parking position and the one in Figure 12 The detection position shown can be adjusted. Preferably, the linear guide 77 is designed as a sleeve that projects in the area of ​​the outer side 31.1 of the crushing chamber boundary 31 and in which the carrier 40 is received.

[0084] If, starting from the in Figure 11 When the actuator 80, which is fixed in position with its cylinder 81 relative to the crushing chamber boundary 31, is actuated in the parking position shown, the piston rod 82 extends from the cylinder 81 and pivots the toggle lever. As a result of this pivoting movement, the coupling 71 is also adjusted. This adjustment causes the actuating element 44 to move in the linear guide 77, so that the detection device 50 is moved into the crushing chamber 30. After the detection of the wear condition of the at least one crushing tool 11.2 is complete, the carrier 40 is returned in the opposite direction until the detection device 50 is in the position shown. Figure 11The vehicle comes to rest in the parking position shown. At the same time, the actuator 44 with its closing mechanism 41.1 closes the inspection opening 32 (see Figure 11 ).

[0085] In the preceding explanations, the functioning of the invention was described using the detection of the wear condition of the crushing tool 11.2 as an example. However, the invention is not limited to this; rather, it is possible that the detection device 50 can additionally or alternatively detect the wear condition of another wear part in the crushing chamber.
