Description

[0001] The invention relates to a mobile shredding device.

[0002] 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 hauling it away. 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 dismantled, there is no longer any material to shred.

[0003] Accordingly, there is a definite need for mobile shredding equipment, with shredders already available in the form of vehicles or trailers. However, in order to load 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.

[0004] 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.

[0005] 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.

[0006] 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.

[0007] 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 frame, on which the shredding tool, and preferably the drive, is mounted. Furthermore, the shredding device has arms connected or connectable to the support structure. Each arm has at least one bearing section for resting on the edge of a receiving device.

[0008] The booms can be easily moved from a transport position to a working position. This can be achieved by swiveling, sliding, or attaching them. In this way, the mobile shredding device can be designed to be very compact for transport and, with the booms and their integrated support sections, can be positioned on the edge of a receiving device, such as a container or similar.

[0009] 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, the shredded material ejected into the receiving unit to be distributed over the entire base of the receiving unit.

[0010] 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.

[0011] 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 their transport position into their operating position. A bolt or other fixing device can then be used to secure them, thus preventing unintentional pivoting of the booms in the operating position.

[0012] 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.

[0013] 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.

[0014] 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 it to accommodate different widths of receiving devices. It is also possible for a boom to have multiple support sections, so that the boom, in a single operating position, allows for placement on receiving devices of different widths.

[0015] 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 also 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 and removed from it again in the operating position.

[0016] The invention also relates to a method for operating a comminution plant for treating material:

[0017] This includes 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 wherein 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.

[0018] This method significantly simplifies the installation and dismantling of a shredding system, particularly when using the mobile shredding device described above. Specifically, it allows the mobile shredding device to be transported to the construction site, for example in a container, the container to be set down, and then the same lifting device used to move the mobile shredding device from the container to its operating position on top of the container.

[0019] 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 in such a way that the comminutioned material enters the room.

[0020] 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 and the comminutioned material in the room can be removed together with the receiving device or separately from it.

[0021] As already indicated above, it may be planned that the mobile shredding device is transported to the installation site in the receiving device.

[0022] Any suitable facility capable of holding material to be shredded can serve as a receiving unit. 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 portable or permanently installed at the site of the mobile shredding equipment.

[0023] 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 arms.

[0024] The invention is described below with reference to the Figures 1-16 and explained in more detail in the examples contained therein. Figure 1 shows a perspective view of a mobile shredding device according to the invention in a first embodiment; Figure 2 shows a partial view of a mobile shredding device according to the invention similar to the first embodiment in a front view; Figure 3 shows a perspective view of a second embodiment of the mobile shredding device according to the invention; Figure 4 shows a perspective view of a receiving device in the form of a skip container; Figure 5 shows a perspective view of a receiving device in the form of a bunker; Figure 6 shows a perspective view of a receiving device in the form of a roll-off container; Figure 7 shows a side view of a mobile shredding device according to the invention in a position of use on a receiving device.Figure 8 shows a side view of a mobile shredding device according to the invention in a transport position within a receiving device; Figure 9 shows the [unclear text].

Figure 15 shows a perspective view of a receiving device with a shredding device placed therein, in the embodiment of Figures 11-13. Figures 1-3 and 7 before being moved into the operating position, Figure 16 shows a perspective view of a receiving device with a shredding device placed therein in an embodiment with a mobile underframe.

[0025] A first embodiment of the mobile comminution device 1 according to the invention is in Figure 1 depicted.

[0026] This has a support structure 5, which is preferably designed – as shown in the figures – in the form of a support frame, 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, be part of the support structure 5 or separate components. According to the invention, outriggers 6 are provided; in the present case, there are preferably four outriggers 6, which extend 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 P1). 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 the example according to . Figure 2 As can be seen from the diagram, struts 61 with a series of holes 62 are provided for this purpose, the struts 61 being hinged to the support structure 5. Holes are also provided on the boom 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 shown). Figure 2(Two support sections 7 are provided in each case), 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 mounted 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 mounted on the boom 6 to ensure that the support sections 7 can rest as flat as possible on the edge of a receiving device. However, this is not mandatory.

[0027] D denotes the axis of rotation of the shredding tool 3, which is shown here as a shredding roller. Shredded material, which is fed into the feed area 2, is thrown into the discharge chute 13 below the shredding tool 3 after shredding by the shredding tool 3.

[0028] 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.

[0029] The embodiment according to Figure 3The design is essentially similar to the previous embodiments. A drive 4 mounted on the support structure 5 is visible, which can rotate the shredding tool 3 about the axis D. Unlike in the previous embodiments, the booms 6 in this case can be pivoted about a vertical axis B, see arrows P. The explanations regarding the support sections 7 in the above embodiments also apply here.

[0030] The mobile shredding device of the present invention is suitable for use with a whole range of receiving devices, for example a skip container according to Figure 4This has an interior or space 82, which is bounded by side walls 81, 83, the upper edges of which are 81a and 83a, respectively. Naturally, there is also a rear wall and a front wall. 84 designates transport sections to which, for example, a lifting device of a dump truck or the like can be attached.

[0031] When executed according to Figure 5 A bunker can be seen where the side walls 81, 83 and also the rear wall can be composed of L-shaped blocks, for example.

[0032] Roll containers, such as those in Figure 6 The components shown are usable in the context of the mobile shredding device according to the invention; here, a rear wall is designated 85. This wall has a bracket 87 to which, for example, a hook on the lifting device of a corresponding transport vehicle can be attached.

[0033] 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. Figure 7 It is therefore indicated how the operation of the mobile shredding device 1 according to the invention can take place in such a case: First, the device is placed with its outriggers on the edge (here 81a) and the (not shown here) edge of the opposite side wall. Then the shredding 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 the Figure 7As shown, only a part of the base 86 (see arrows) is covered with shredded material 9. In order to completely fill the remaining part of the base 86 and thus the interior space via the discharge 13, the mobile shredding device 1 (see arrows P2) can be moved on the edge 81a of the receiving device 8, especially if the support sections are equipped with rollers.

[0034] The Figures 8-10 show a possible transport variant of the comminution device according to the invention 1.

[0035] As in Figures 8 and 9 As can be seen, the shredding device 1 can be housed in the transport position inside the interior 82 of the receiving device 8 – designed here as a drop-off container – and transported to or from the installation site within it. As can be seen particularly in the Figure 9As can be seen, the outriggers 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. The transport sections 84 located on the receiving device 8 can be used – as shown in Figure 10 As shown, a lifting device 10 of a transport vehicle, which is coupled here to the transport sections 84 via chains or traction elements 11, loads the receiving device 8 onto the transport vehicle or sets it down from it at the installation site. Simultaneously, the lifting device 10 can also be used to lift the mobile shredding device 1 from the transport position shown to the operating position. For this purpose, the traction elements are attached, for example, to the transport sections 21 (see figure). Figure 1) the mobile shredding device 1 is coupled. When the mobile shredding device 1 is then lifted via the lifting means 10, the booms can be moved into the operating position and the mobile shredding device can subsequently 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 in the Figures 8-10 In the variant shown, 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.

[0036] It is also conceivable to transport the mobile shredding device 1 without a container. For this purpose, a substructure 12 can be attached to the support structure 5, as shown in the Figures 11-13This 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 in Figure 13 As shown, the transport sections 21 can again be used on the mobile shredding device 1 to couple it with the lifting means 10, for example via traction means 11.

[0037] In the Figures 14-16 Examples of different embodiments of the mobile shredding device 1 in a receiving device 8, for example a roll container, are shown. The previously mentioned [reference to the] Figures 11-13The described underframe can, for example, be lowered onto the base 86 of the receiving device 8 using a wheel loader or forklift. The mobile shredding device 1 is then lifted using the wheel loader, forklift, or any other lifting device, and the booms are moved into the operating position. The mobile shredding device is then lowered onto the edge of the receiving device.

[0038] Similarly, this can be the case with the Figure 15 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, be it on the transport vehicle or a separate lifting device such as a wheel loader or forklift.

[0039] In Figure 16Finally, a further embodiment of the mobile shredding device according to the invention is shown 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 the Figures 14 and 15 described, to be transferred into the operating position.
