Description

[0001] MOBILE SHREDDING DEVICE AND METHOD FOR

[0002] OPERATING A SHREDDING PLANT

[0003] TECHNICAL AREA

[0004] The invention relates to a mobile shredding device.

[0005] STATE OF THE ART

[0006] Construction sites, in particular, generate a lot of rubble and other waste. Not only is the separation of these materials important, but also the optimal utilization of available containers, which are then transported for disposal or further processing. It is therefore advisable to shred the material to be removed on-site before transport. There are shredding devices that are installed on-site so that waste containers can be placed underneath them. However, such permanent installations are only suitable where material requiring shredding is constantly being generated. This is less suitable for construction sites, for example, because once the site is closed, there is no longer any material to shred.

[0007] Accordingly, there is a definite need for mobile shredding devices, with shredders already known to be designed as vehicles or vehicle trailers. However, in order to fill a suitable container with the shredded material on site, these devices are also more or less complex to install or operate and require a significant amount of space.

[0008] THE INVENTION

[0009] The object of the present invention is to provide a mobile shredding device which minimizes the required space and in particular enables short-term on-site use and can be installed relatively quickly.

[0010] This problem is solved by a mobile comminution device with features of claim 1 and a method according to claim 9. Advantageous embodiments are found in the respective dependent claims.

[0011] The present invention is based on the finding that the mobile shredding device does not require a complex substructure for inserting receiving devices, such as containers. This is achieved by allowing the mobile shredding device to be installed on the rim of a container to be loaded with material to be shredded. The container itself thus provides the necessary substructure. In this way, the mobile shredding device can be installed in a space-saving manner. This also offers advantages during transport, as the mobile shredding device according to the present invention can be kept relatively compact and thus transported using conventional transport equipment.

[0012] The mobile shredding device according to the invention for shredding material comprises a shredding unit with a feed area for introducing material to be shredded and a shredding tool, preferably driven by a drive, as well as a support structure, preferably designed as a support frame, on which the shredding tool, and preferably the drive, is mounted. Furthermore, the shredding device has booms connected or connectable to the support structure. Each boom has at least one bearing section for resting on the edge of a receiving device.

[0013] The booms can preferably be moved from a transport position to a working position. This can be done by pivoting, sliding, or attaching them. In this way, the mobile shredding device can be designed to be very compact for transport and can be positioned for use on the edge of a receiving device, such as a container or the like, using the booms and the support sections provided on them.

[0014] The support sections can be simple surfaces on the boom; however, in a preferred embodiment, at least one of the support sections has at least one roller. The rollers have the advantage that the mobile shredding device can be moved along the edge of the receiving unit after installation. This allows, particularly with larger receiving units, shredded material dropped into the receiving unit to be distributed over the entire base area of ​​the receiving unit.

[0015] The outriggers or support sections can have locking devices that allow them to be fixed to the wall of the receiving device, preventing the installed mobile shredding unit from slipping on the edge of the receiving device. This ensures operational safety. Corresponding projections can be arranged at the outer end of the outriggers, engaging behind the outer surface of the walls of the receiving device, thus preventing the mobile shredding unit, which preferably has multiple outriggers, in particular at least four outriggers, from rotating on the receiving device, for example, about a vertical axis.

[0016] In a preferred embodiment, at least one boom is pivotably mounted on the support structure about a pivot axis. This embodiment is particularly advantageous because, for installation, only the booms need to be swung from the transport position into the operating position. A bolt or other fixing can then be used to secure them, thus preventing unintentional pivoting of the booms in the operating position.

[0017] A preferred embodiment may include an embodiment in which at least one boom can be fixed in at least two different swivel angle positions relative to the supporting structure. This allows for different operating positions, which, depending on the width of the receiving device (i.e., the distance between two opposing side walls), require different boom spans.

[0018] Preferably, at least one of the support sections is pivotally mounted on the associated boom. Alternatively or additionally, it may also be provided that at least one of the booms is displaceable or relocatable relative to the supporting structure. In addition to pivoting movements, translational movements of the booms relative to the supporting structure are also conceivable, either alternatively or additionally.

[0019] According to a further preferred embodiment of the mobile shredding device according to the invention, at least one of the support sections along the associated boom can be fixed in different positions. This also offers the possibility of arranging the support section at different points along the boom, thereby enabling the device to accommodate different widths of receiving devices. It is also possible for a boom to have multiple support sections, so that the boom, in just a single operating position, allows the material to be placed on receiving devices of different widths.

[0020] Finally, the mobile shredding device can have at least one transport section for engaging a lifting device of a transport vehicle. In this way, for example, the mobile shredding device according to the invention can be moved using a conventional lifting device of container vehicles, dump trucks, wheel loaders, forklifts, etc., and in particular, placed on the edge of a receiving device in the operating position and removed from it again.

[0021] The invention also relates to a method for operating a comminution plant for treating material:

[0022] This method comprises the following steps: a. Providing a receiving device for receiving shredded material at an installation site, wherein the receiving device has at least two opposing walls, each with an upper edge, and a space for receiving shredded material is formed between the walls; b. Providing a mobile shredding device at the installation site; c. Placing the mobile shredding device on the receiving device such that the mobile shredding device rests on the walls. This method significantly simplifies the installation and removal of a shredding plant, particularly when using the mobile shredding device described above.Above all, it offers the possibility of transporting the mobile shredding device to the construction site, for example in a container, setting down the container there and then using the same lifting device to move the mobile shredding device from the container into the operating position on the container.

[0023] According to a preferred embodiment of the method according to the invention, it can be provided that after step c, the following step is carried out: d. Comminution of material using the mobile comminution device such that the comminutioned material enters the room.

[0024] Once the comminution process is complete and the corresponding receiving device is ready to depart, according to the invention, the mobile comminution device can be released from the support on the receiving device after step d. and the comminutioned material in the room can be removed together with the receiving device or separately from it.

[0025] As mentioned above, the mobile shredding device can be transported to the installation site in a receiving unit. Any suitable receiving unit can be used to store material to be shredded. For example, the receiving unit could be a container, particularly a skip container, a roll-off container, a roll-off compactor container, or a bunker. The receiving unit itself can therefore be transportable or permanently installed at the installation site of the mobile shredding device.

[0026] Especially with larger receiving devices, the relatively compact mobile shredding unit can only be placed on a portion of the receiving device. The discharge area of ​​the shredded material is therefore often limited to a section of the receiving device's base. According to a preferred embodiment of the inventive method, the mobile shredding unit can therefore be moved along the walls during or after a shredding process. This variant is particularly feasible if rollers or similar components are provided on the outriggers.

[0043] BEST WAY TO IMPLEMENT THE INVENTION

[0044] A first embodiment of the mobile comminution device 1 according to the invention is shown in Figure 1.

[0045] This has a support structure 5, which is preferably designed – as shown in the figures – in the form of a support frame, and on which the shredding unit with a shredding tool 3 and a – here funnel-shaped – feed area 2 is mounted. The walls of the feed area 2 can, for example, form part of the support structure.

[0046] 5 or separate components. According to the invention, outriggers 6 are provided; in the present case, there are preferably four outriggers 6 extending outwards in the transverse direction Y from the support structure 5. X denotes the longitudinal direction, Z denotes the vertical direction. In the example shown, the outriggers 6 are pivotably mounted on the support structure 5 about an axis A. They can be pivoted from a (folded) transport position to an unfolded operating position shown here and back again (see arrows PI). In the operating position, the outriggers 6 can preferably be locked in a corresponding position. In the example shown – as can also be seen in particular from the example according to Figure 2 – struts 61 with a series of holes 62 are provided for this purpose, wherein the struts 61 are hinged to the support structure 5. On the outrigger

[0047] Holes are also provided in Figure 6 into which a corresponding bolt 63 can be inserted to fix the strut 61 to the boom 6. In the example shown, at least two holes are provided on the boom 6 through which the bolt 63 can be guided. This allows different pivot positions to be fixed. At least one support section 7 is arranged on the boom 6 (in the example of Figure 2, there are two support sections 7), which in the example shown can preferably be designed as a roller. Other support sections 7 are also conceivable. Furthermore, in the example shown, the support section 7 is arranged on a bearing 72. The bearing 72 can in turn be pivotally arranged on the boom 6, for example via a bolt 71. Here, too, several holes 65 can be provided to allow the bolt 71, and thus the bearing 72, to be positioned at different locations on the boom 6.This allows the distances between the support sections 7 of opposing booms 6 to be varied, so that the mobile shredding device 1 can be supported on receiving devices of different widths. The bearing 72 can also be pivotally attached to the boom 6, ensuring that the support sections 7 lie as flat as possible on the edge of a receiving device. However, this is not strictly necessary.

[0048] D denotes the axis of rotation of the shredding tool 3, which is shown here as a shredding roller. Shredded material, which is placed in the feed area 2, is thrown into the discharge chute 13 below the shredding tool 3 after shredding by the shredding tool 3.

[0049] In the example shown, transport sections are marked with 21, which are provided here in the form of pins or the like and serve to enable the mobile shredding device 1 to be lifted, for example by means of a lifting device.

[0050] The embodiment according to Figure 3 is fundamentally similar to the previous embodiments. A drive 4 mounted on the support structure 5 can be seen, which can rotate the shredding tool 3 about the axis D. Unlike in the previous embodiments, the booms 6 in this case can pivot about a vertical axis B, see arrows P. The descriptions of the above embodiments regarding the support sections 7 also apply here accordingly.

[0051] The mobile shredding device of the present invention is suitable for use with a whole range of receiving devices, for example, a skip container as shown in Figure 4. This container has an interior or chamber 82, which is bounded by side walls 81, 83, having upper edges 81a and 83a, respectively. Naturally, there is also a rear wall and a front wall. 84 denotes transport sections to which, for example, a lifting device of a dump truck or the like can be coupled.

[0052] The embodiment shown in Figure 5 is a bunker in which the side walls 81, 83 and also the rear wall can be composed of L-shaped blocks, for example.

[0053] Roll containers, such as those shown in Figure 6, can also be used in connection with the mobile shredding device according to the invention; here, a rear wall is designated 85. This has a bracket 87 to which, for example, a hook on the lifting device of a suitable transport vehicle can be attached.

[0054] Since the mobile shredding device 1 is relatively compact, it does not extend over the entire discharge opening of some receiving devices, such as roll containers, but only ever covers a partial area of ​​the interior 82 of a receiving device 8.

[0055] Figure 7 therefore illustrates how the operation of the mobile shredding device 1 according to the invention can proceed in such a case. It is first placed with its outriggers on the edge (here 81a) and the (not shown here) edge of the opposite side wall. The shredding then takes place, and the shredded material 9 enters the interior 82 and is deposited on the floor 86 of the receiving device. As shown in Figure 7, only a portion of the floor 86 (see arrows) is covered with shredded material 9. To completely fill the remaining portion of the floor 86 and thus the interior via the discharge 13, the mobile shredding device 1 (see arrows P2) can be moved along the edge 81a of the receiving device 8, particularly if the support sections are equipped with rollers.

[0056] Figures 8-10 show a possible transport variant of the comminution device 1 according to the invention.

[0057] As can be seen in Figures 8 and 9, the shredding device 1 can be housed in the transport position inside the interior 82 of the receiving device 8 – here designed as a drop-off container – and transported to or from the installation site. As can be seen particularly in Figure 9, the booms 6 of the mobile shredding device are folded up in the transport position, and the support sections 7 rest upright on the edge 81a or 83a of the side walls 81 or 83. The mobile shredding device is thus suspended in the receiving device 8. Using the transport sections 84 located on the receiving device 8, a lifting device 10 of a transport vehicle – which is coupled to the transport sections 84 via chains or traction elements 11 – can load the receiving device 8 onto the transport vehicle or lower it from the vehicle to the installation site, as shown in Figure 10.Simultaneously, the lifting device 10 can also be used to raise the mobile shredding device 1 from the illustrated transport position to the operating position. For this purpose, the traction elements are coupled, for example, to the transport sections 21 (see Figure 1) of the mobile shredding device 1. Once the mobile shredding device 1 is raised via the lifting device 10, the booms can be moved into the operating position and the mobile shredding device can then be placed on the upper edges of the receiving device 8. After the shredding process, the same procedure can be carried out in reverse order. With the variant shown in Figures 8-10, it is also possible to transport the shredded material 9 together with the mobile shredding device 1 in the same container after the shredding process.

[0058] It is also conceivable to transport the mobile shredding device 1 without a container. For this purpose, a base frame 12 can be attached to the support structure 5, as can be seen in Figures 11-13. This base frame 12 serves to place the mobile shredding device 1 on the transport surface of a transport vehicle by means of supports 12a located on the base frame 12 – for example, in the form of feet or skids. As shown in Figure 13, the transport sections 21 can again be used on the mobile shredding device 1 to couple it to the lifting device 10, for example, via a traction element 11.

[0059] Figures 14-16 show exemplary embodiments of the mobile shredding device 1 in a receiving device 8, for example, a roll container. The underframe described above with reference to Figures 11-13 can be placed on the base 86 of the receiving device 8, for example, using a wheel loader or forklift. The mobile shredding device 1 is then lifted with the wheel loader, forklift, or any other lifting device, and the booms are moved into the operating position. The mobile shredding device is then placed on the edge of the receiving device.

[0060] A similar approach can be taken in the case of Figure 15. Here, the mobile shredding device 1 is simply placed on the ground 86 with its support structure 5. Lifting can then be carried out using any lifting device, whether on the transport vehicle or a separate lifting device such as a wheel loader or forklift.

[0061] Finally, Figure 16 shows another embodiment of the mobile shredding device according to the invention in the receiving device 8. Here, the mobile shredding device with a base frame 12 with wheels can be pushed directly to the installation site and then subsequently, as already described above with reference to Figures 14 and 15, moved into the operating position.
