Description

[0001] The present invention relates to a turning roller for a mobile turner for turning bulk material, in particular for turning a compost heap, comprising a roller body and at least one tool arrangement arranged on the roller body, wherein the tool arrangement includes a tool holder and a turning tool arranged on the tool holder. Furthermore, the present invention relates to a mobile turner for turning bulk material, in particular a compost heap, comprising a vehicle chassis and a turning roller of the aforementioned type, rotatable about a rotational axis, in particular a rotor central longitudinal axis, and mounted on the vehicle chassis.

[0002] Compost turners and mobile turners are used to turn mostly triangular compost heaps, also known as triangular windrows. The triangular shape of the compost heap refers specifically to its cross-section. Ultimately, a mobile turner can turn an elongated pile of compost heaps with a triangular cross-section. However, these turners are not limited to triangular compost heaps and can be used to turn compost heaps of any cross-section.

[0003] Turning the compost heap with a mobile turner accelerates the composting process of the bulk material, particularly because the mobile turner and the turning of the material allow air and oxygen to be introduced, thus speeding up the composting process. In this respect, turning the compost heap promotes and accelerates its decomposition, which is generally desirable to achieve the highest possible throughput of compost material and ultimately an economically viable composting operation.

[0004] Mobile compost turners are known from the prior art, for example from DE 202 07 485 U1. DE 202 07 485 U1 relates to a vehicle for turning compost windrows, wherein the vehicle has a running gear and a chassis supported by the running gear, as well as a compost processing roller mounted on the chassis and rotatably driven. The compost processing roller is equipped with appropriate tools for picking up and throwing up material from the triangular windrows. The chassis spans the composting roller in a bridge-like fashion, and the composting roller is rotatably mounted on the chassis about a horizontal transverse axis. The composting roller has throwing tools for throwing up the bulk material. To achieve a triangular deposit of the compost windrow, the composting roller is also equipped with inwardly extending augers.In addition, there is a passage channel between the composting roller and the underside of the vehicle chassis, through which the thrown compost can be flung before it piles up again in a triangular shape behind the roller.

[0005] The mobile compost turner known from DE 202 07 485 U1 does accelerate the decomposition of the compost heap. However, this acceleration is insufficient, as higher acceleration rates and more efficient composting processes are desired in practice. Consequently, the composting efficiency is inadequate, and numerous turning cycles are usually necessary, resulting in high personnel and operational costs. Furthermore, the mobile compost turner known from DE 202 07 485 U1 has proven inadequate or in need of improvement with regard to minimizing the shredding effect of contaminants in the material, such as films, plastics, paper, or similar materials, and to ensuring gentle handling of the compost material. Improvements are also needed concerning reduced wear and tear and the associated reduction in maintenance requirements.

[0006] The object of the present invention is therefore to provide a transfer roller and a mobile transfer unit for transferring bulk material, by which the aforementioned disadvantages are to be overcome or at least substantially reduced.

[0007] In particular, the object of the present invention is to provide a turning roller and a mobile turner of the type mentioned above, thereby enabling an efficient and simultaneously economically and technically sustainable composting process. In this respect, the invention aims to cover or fulfill the broadest possible range of applications within the composting process.

[0008] According to the invention, the problem of a transfer roller of the type mentioned above is solved by the fact that a central transverse axis of the transfer tool, which runs through a front side of the transfer tool facing away from the tool holder, includes an angle of rotation between 1° and 30°, preferably between 3° and 20° and in particular between 12° ± 3°, to a rotor central longitudinal axis of the roller body.

[0009] In connection with the development of the invention, it has been recognized that the alignment of the turning tools in the defined rotation angle ranges relative to the rotor's central longitudinal axis leads to a reduction in wear and consumption costs and overall to an efficient composting process.

[0010] During the implementation process, the transfer tools aligned according to the invention engage with the bulk material under reduced material resistance, whereby the bulk material striking the front side interacts gently with the transfer tool and is simultaneously subjected to an intensive transfer or circulating movement.

[0011] The orientation of the transfer tools or the orientation of their rotation angle relative to the rotor's central longitudinal axis is particularly preferred such that, in conjunction with the transfer tools, the bulk material is transported or conveyed towards the center of the roller body due to the rotation of the transfer roller. In this respect, the circulation of the bulk material by the transfer tools is preferably superimposed or combined with a simultaneous transport or conveying movement towards the center of the transfer roller, which enables or promotes the formation of a triangular pile.

[0012] As a result of the orientation of the transfer tools, the rotor speed of the roller body or transfer roller can be reduced by up to 30% during operation of the mobile transfer unit. This is correspondingly accompanied by a reduction in fuel and operating resource consumption of up to 25%, especially compared to an orientation of the front of the tool parallel to the rotor's central longitudinal axis. Furthermore, the solution according to the invention enables low-wear and maintenance-friendly operation, while simultaneously allowing for gentle handling of the material being transferred and a reduced comminution effect on contaminants in the material, such as film, plastic, paper, or glass.

[0013] The selected angle ranges of 1° to 30° were determined during practical testing in the development of the present invention, revealing an optimized balance of reduced resource consumption, decreased wear, and gentle material handling. Further improvements are achieved in the angle range between 3° and 20°. Particularly efficient composting is achieved at rotation angles of 12° to 15°.

[0014] According to the invention, a central transverse axis is understood to be a line or straight line running through the front face of the transfer tool, which runs obliquely or skew to the rotor's central longitudinal axis. The central transverse axis and the rotor's central longitudinal axis can run in two mutually parallel planes, between which a tangential plane adjacent to the outer surface of the roller body can lie, which also runs parallel to the plane of the central transverse axis on the one hand and the plane of the rotor's central transverse axis on the other. In this respect, the central transverse axis preferably has no radial component with respect to the roller body.

[0015] According to a further, preferred embodiment of the invention, which, however, also has independent significance, it is provided that a central longitudinal axis of the transfer tool, running away from the tool holder on the front side of the transfer tool, includes a tilting angle of at least 5°, preferably between 5° and 55°, more preferably between 10° and 50°, and in particular between 30° and 40°, with a tangent to an outer surface of the roller body, which intersects the central longitudinal axis at an intersection point on the outer surface of the roller body.

[0016] This embodiment can alternatively or additionally be realized by enclosing a first plane, facing away from the tool holder, with a tilt plane angle of at least 5°, preferably between 5° and 50°, more preferably between 10° and 40°, particularly between 30° and 35°, to one, in particular to all, tangential plane(s) on an outer surface of the roller body, which intersects the first plane in a section line on the outer surface of the roller body.

[0017] Accordingly, the present invention also proposes a tilting of the transfer tool or its front side towards the outer surface of the roller body.

[0018] By tilting the material within defined tilting angle ranges, intensive homogenization of the bulk material and ultimately efficient composting are achieved. This is particularly important because, even after the mobile turner has passed over the compost heap, a new compost heap, especially a triangular one, can be formed. In this respect, this aspect of the invention contributes to better mixing and aeration of the compost heap, and / or to complete homogenization of the bulk material. This also contributes to improved decomposition and composting, drastically reducing the decomposition time until the compost heap is completely decomposed, preferably by at least 30%, especially compared to turner rollers not equipped with the tilting turning tools according to the invention.

[0019] According to the invention, a central longitudinal axis is understood to be, in particular, the longitudinal axis and / or central axis of the transfer tool. Preferably, the central longitudinal axis runs through the center of gravity or at least substantially through the center of gravity of the transfer tool. Accordingly, the central longitudinal axis runs, in particular, centrally through the transfer tool and / or along its longitudinal extent, where the longitudinal extent indicates that the transfer tool may have a greater length than width. However, this is not mandatory. The transfer tool may also have substantially the same length and width or a shorter length than width. The central longitudinal axis may, in particular, run at least substantially parallel to the longitudinal edges of the transfer tool. The central longitudinal axis can therefore also be understood as a longitudinal and / or symmetry axis of the transfer tool.Ultimately, the central longitudinal axis runs in the direction of the greatest extent of the transfer tool and / or at least partially radially to the transfer roller, whereas the central transverse axis runs transversely to this axis or in the direction of a reduced extent of the transfer tool and / or at least partially radially to the transfer roller. It should be noted that the above aspect of the invention with regard to tilting can, in principle, also be realized without the aforementioned rotation of the central transverse axis relative to the rotor's central longitudinal axis, and this therefore constitutes an independent aspect of the invention.

[0020] However, it is also possible, and indeed preferred, to combine the aforementioned tilting with the rotation of the turning tool. In this context, it has been found within the scope of the present invention that a combined measure of rotation and tilting results in a particularly resource-saving and simultaneously efficient turning or composting process, leading to improved homogenization and accelerated decomposition while simultaneously reducing operating costs and wear and maintenance requirements. In this respect, these two aspects of the invention complement each other in a mutually reinforcing or synergistic manner, resulting in a particularly efficient and sustainable turning process.

[0021] Accordingly, the combination of alignment within the defined rotation and tilt angle range enables fuel consumption to be reduced by up to 40% compared to previously known mobile converters. Conversion performance can be significantly improved, in particular by up to 150% compared to previously known conversion performance, while simultaneously achieving a corresponding reduction in annual operating hours and costs. Furthermore, the reduction in fuel consumption and operating hours also leads to a reduction in greenhouse gas emissions, such as reduced carbon dioxide emissions.

[0022] From a design perspective, the special feature of the transfer roller according to the invention lies particularly in the fact that the orientation of the transfer tool within the specified rotation and tilt angle range is determined by the tool holder itself. Accordingly, the tool holder is designed to fix or hold the transfer tool both within the defined rotation angle range relative to the rotor's central longitudinal axis and within the defined tilt angle range with respect to the outside of the transfer roller or the tangent. Therefore, modifications or deformations to the transfer tool itself, for example in the form of bends, folds, and / or protrusions, are not necessary to achieve the desired orientation within the rotation and tilt angle range. This is accomplished by the design and orientation of the tool holder itself.

[0023] Preferably, the tilting plane angle and / or the tilting angle is / are larger than the rotation angle, in particular by at least 20%, preferably between 30% and 500%, more preferably between 70% and 300%.

[0024] It has proven advantageous to select a smaller rotation angle than the tilting angle or tilting plane angle. For example, a comparatively small rotation angle is sufficient or even optimal for achieving energy-efficient and low-wear mixing in the longitudinal direction. Conversely, a larger tilting angle or tilting plane angle is advantageous for mixing the bulk material radially or for homogenizing it over a wide radial range. In combination with the defined rotation and tilting angles, an optimized compromise can thus be achieved with regard to optimized mixing or composting, while simultaneously optimizing energy consumption and reducing wear.

[0025] Furthermore, it is stipulated that the transfer tool is designed as a plate-like and / or one-piece and / or as a sheet metal or undeformed semi-finished product. In other words, it is specifically stipulated that the entire front surface of the plate-like transfer tool is planar, i.e., undistorted and / or undeformed, meaning free of twisting or protrusion.

[0026] The use of plate-like or plate-shaped transfer tools, preferably as planar or undeformed semi-finished products, saves costs and resources. Replacement is also straightforward, enabling maintenance-friendly and efficient operation. The planar or plate-shaped design is made possible primarily by the tool holder, which implements the orientation in the direction of rotation or tilting. Therefore, no geometric modifications to the transfer tool itself are necessary.

[0027] In particular, it is intended that the longitudinal alignment and / or the tilting towards the transfer roller do not have to be implemented by geometric deformations of the transfer tool, but are specified by the alignment or design of the tool holder.

[0028] The transfer tool has a shape that is at least essentially trapezoidal or rectangular, in particular a rhomboid shape, when viewed from above or from the front.

[0029] The diamond-shaped design has proven advantageous in promoting or enhancing the effect of gentle and low-wear composting.

[0030] The transfer tool is aligned such that its upper surface is offset from its lower surface towards the center of the roller body. In this respect, the upper corner edges of the transfer tool are offset from their corresponding lower corner edges towards the center of the transfer roller. This alignment further promotes wear on the transfer tool.

[0031] The transfer tool can be attached to the tool holder by force-fit and / or form-fit, in particular by at least one screw connection, preferably by at least two screw connections. This allows for efficient maintenance or easy replacement of the transfer tools.

[0032] The tool holder is preferably firmly connected to the roller body, in particular by a material bond, preferably welded.

[0033] As regards the tool holder, it preferably has a lower base section attached to the roller body and an upper fastening section adjoining the base section for the, in particular detachable, fastening of at least one transfer tool.

[0034] It has proven advantageous if the mounting section is tilted relative to the base section in the direction of the outer surface of the roller body. The base section preferably projects radially, or without tilting, from the roller body. This arrangement allows loads or torques acting on the mounting section to be transferred gently into the roller body via the base section, particularly due to the base section's straight, radial orientation and the resulting reduced leverage. Consequently, the mechanical stress in the connection area between the base section and the roller body is reduced, enabling reliable operation and lower maintenance requirements.

[0035] In this context, it is particularly preferred that a mounting surface of the mounting section which is tilted towards the outer surface of the roller body forms an angle between 140° and 179°, preferably between 150° and 175°, with an end face of the base section which adjoins the mounting surface downwards.

[0036] Accordingly, the tilt angle or tilt plane angle is determined by the orientation of the mounting surface or mounting section relative to the base section.

[0037] Furthermore, reinforcing ribs may be provided that project laterally from the mounting surface of the mounting section and / or side ribs project laterally from the end face of the base section, in particular wherein the reinforcing ribs and the side ribs are firmly connected to each other, preferably welded. This enables a mechanically robust and torsionally rigid connection between the base section and the mounting section.

[0038] In particular, it is provided that the tool holder, preferably the base section and / or mounting section, is / are designed as a profile open on one side, especially a U-profile, and / or has / have a U-shaped profile at least in part. This allows for a simple and weight-saving design while maintaining sufficient stability.

[0039] Preferably, the minimum distance between the top edge of the transfer tool and the outer surface of the roller body is at least 280 mm, more preferably between 280 mm and 320 mm, and further preferably between 290 mm and 310 mm. Particularly due to the connection via the tool holder, comparatively large distances between the top edge of the transfer tool and the outer surface of the white body can be achieved, allowing the transfer tools to penetrate deeply into the bulk material and thus efficiently homogenize or convert the material.

[0040] Preferably, the transfer tools are aligned along at least one spiral line extending at least substantially spirally around the roller body. Alternatively or additionally, adjacent transfer tools along a spiral line are arranged at least substantially equal intervals, in particular wherein transfer tools are arranged circumferentially between 5 and 15, preferably between 6 and 14, and more preferably between 8 and 12, on each complete turn of the spiral line.

[0041] The arrangement of the turning tools along a spiral line enables thorough mixing of the bulk material and simultaneously a triangular structure of the compost pile after turning. Thus, the spiral arrangement offers significant advantages for the implementation according to the invention.

[0042] Preferably, the roller body has a repositioning area with opposing spiral lines and repositioning tools arranged along these lines on its axial outer sides or on its axially outer regions, with a central area containing throwing tools provided between the repositioning areas. In particular, the throwing tools are arranged in several rows.

[0043] In this context, it is understood that, in addition to the transfer areas and the central area, further areas may be provided on the roller body. In any case, the transfer tools are provided in the transfer areas. It is particularly preferred that only or exclusively transfer tools of the type according to the invention are arranged in a transfer area. It may also be provided that the central area is free of transfer tools of the type according to the invention.

[0044] However, the throwing tools can also be considered additional turning tools, as they also contribute to the turning of the compost heap. For the purposes of the present invention, however, "turning tools" refers to a specific embodiment of the tool, and thus this term applies to this particular embodiment of the invention. Further embodiments of the additional tools are designated accordingly.

[0045] Preferably, end areas are provided between the respective end face of the roller body and the respective conversion area, with engagement tools being arranged in the end area.

[0046] It is preferably provided that the engagement tools have a first section, in particular a plate-shaped section, and a second section, in particular a plate-like section, angled relative to the first section along an engagement bending edge.

[0047] The engagement tools can also be functionally considered transfer tools, but they do not constitute the transfer tools according to the invention. Therefore, the present invention distinguishes between engagement tools and transfer tools, with transfer tools always referring to the first or the second alternative according to the invention. The engagement tools of an end region can be arranged along a further spiral line extending at least substantially spirally around the roller body. This further spiral line can transition at least substantially directly into the spiral line of the transfer regions, so that the transfer tools in the transfer region are arranged in the same spiral line as the engagement tools in the end region. The roller body can have two end faces that form the respective longitudinal ends of the roller body. Thus, the roller body can be structured longitudinally as follows: End area - conversion area - middle area - conversion area - end area

[0048] In this context, it is understood that the end region and / or the central region is / are free of the conversion tools according to the invention. However, conversion tools according to the invention can also be used, at least partially, either in the central region or in the end region.

[0049] In a further preferred embodiment, the engagement tools are arranged along at least one helix projecting from the roller body like a web. The helix can, in particular, at least substantially coincide with the helix line for the engagement tools and / or be aligned along this helix line. Thus, the helix can be provided at least in the end regions.

[0050] The helix is ​​particularly preferably composed of helical segments that are at least substantially straight and arranged in a series. The helical segments can have different configurations relative to each other. Preferably, a second helical segment, running at an angle to the first adjacent helical segments, is provided between two initial helical segments on which the engagement tools are arranged. This results in a helix that is at least substantially spiral in shape and can be composed of individual straight segments.

[0051] The second helix section preferably has a circular arc-shaped recess at its upper edge. This recess serves to improve material transfer. The helix also allows the engagement tools to be positioned away from the outer surface of the roller body. This arrangement on the helix enables a distance from the outer surface of the roller body.

[0052] The first helical section can preferably be at least substantially cuboid in shape. However, other embodiments of the first helical sections are also conceivable.

[0053] The two helixes in the opposite end area are preferably arranged in opposite directions.

[0054] In a further, particularly preferred embodiment, the engagement tools project beyond or extend beyond the helix. In a further preferred embodiment, the engagement tools, in particular with their upper edge, project from the helix by preferably at least 5 mm to 100 mm, preferably between 5 mm and 40 mm.

[0055] The throwing tools can preferably be arranged in several rows. Preferably, at least two, and more preferably between 3 and 20, throwing tools are arranged in each row. The throwing tools can, in particular, have a plate-like lower base section and a throwing section projecting outwards from the base section. The throwing section can also be curved relative to the base section. The rows of tools themselves can also be curved.

[0056] The previously described preferred embodiment of the arrangement of the throwing tools enables an optimized upward throwing of the bulk material, which is fed to the throwing tools via the transfer tools.

[0057] Preferably, the throwing tools of a series are arranged such that at least two adjacent throwing tools form an obtuse angle with each other, preferably between 140° and 175°. It is particularly preferred that, with respect to a central throwing tool, two adjacent throwing tools each form an obtuse angle with the central throwing tool, preferably of the same shape. This arrangement allows for a substantially curved design of the series, even if the throwing tools themselves are straight and not curved.

[0058] The engagement tools preferably have a first section, particularly plate-like, and a second section, particularly plate-like, which is angled relative to the first section along an engagement bending edge. The engagement bending edge is particularly preferably at least substantially parallel to the upper edge of the second section and / or parallel to the lower edge of the first section.

[0059] Furthermore, in both the first and the second alternative according to the invention, engagement tools and / or throwing tools can be used or provided which preferably do not have a bend or, in particular, are not bent.

[0060] According to the invention, rotor speeds for the turning roller between 100 and 200 rpm, and in particular between 120 and 160 rpm, can be ensured. Rotor speeds of the aforementioned type enable, in particular, gentle material handling as well as process optimization in terms of compost heap formation, oxygen input, and decomposition time.

[0061] The outer diameter of the transfer roller in the area of ​​the transfer tools can be between 1200 mm and 2000 mm, preferably between 1300 mm and 1700 mm, and particularly between 1400 mm and 1500 mm. Accordingly, the outer radius of the transfer roller in the area of ​​the transfer tools can be between 700 mm and 750 mm.

[0062] The outer radius of the roller body is particularly preferably between 200 mm and 900 mm, and more preferably between 300 mm and 600 mm.

[0063] The roller body preferably has a length or axial extent between 3000 mm and 6000 mm, preferably between 4000 mm and 5000 mm.

[0064] Furthermore, the present invention relates to a mobile transfer unit for transferring bulk material, in particular a compost heap, comprising a vehicle chassis and a transfer roller rotatable about a rotary axis and mounted on the vehicle chassis according to one of the embodiments described above.

[0065] In this context, it is understood that preferred embodiments and advantages of the transfer roller also apply in the same way to the transfer unit and / or vice versa - without this requiring any further explicit explanation.

[0066] Preferably, the converter is designed to be self-propelled. Alternatively or additionally, it can also be provided that the converter can be operated by an operator, who can, for example, sit in a driver's cab mounted on the vehicle chassis.

[0067] Preferably, the vehicle chassis has a running gear and / or is supported by a running gear. Various types of running gear are possible; for example, wheels or tracks can be used for propulsion. This must be adapted to the specific usage situation.

[0068] In particular, the vehicle chassis spans the turning roller in a bridge-like fashion, specifically in such a way that a channel for the bulk material to pass through is formed between the vehicle chassis and the turning roller. Thus, the turner enables the turning of the compost heap and, in particular, the re-piling or re-piling of the compost heap, with the bulk material passing through the channel of the vehicle chassis. Accordingly, the turner can be adapted to the shape of the compost heap, preferably a triangular heap.

[0069] Furthermore, the present invention also relates to the use of a preferably plate- and / or diamond-shaped transfer tool for a transfer roller for a mobile turner for turning bulk material, in particular a compost heap, wherein the transfer tool is arranged on a roller body of the transfer roller via a tool holder in such a way that a central transverse axis of the transfer tool running through a front side of the transfer tool facing away from a tool holder to a rotor central longitudinal axis of the roller body includes an angle of rotation between 1° and 30°, more preferably between 3° and 20° and in particular 12° + / - 3°.

[0070] According to a preferred application, the transfer tool is held on the roller body in such a way that the central longitudinal axis of the transfer tool, which runs through the front of the transfer tool, forms a tilting angle of at least 5°, preferably between 5° and 55°, more preferably between 10° and 50°, and in particular between 30° and 40°, with a tangent to an outer surface of the roller body which intersects the central longitudinal axis at an intersection point on the outer surface of the roller body.

[0071] Accordingly, the transfer tool, which is particularly plate- and / or diamond-shaped, can be used in a transfer roller according to the first and / or second alternative of the invention described above. In this way, corresponding advantages can be realized.

[0072] In this context, it is understood that reference may be made to the preceding descriptions regarding the advantages and preferred embodiments of the transfer tool, which can apply equally to the aforementioned use according to the invention. The descriptions relating to the use according to the invention can also be applied equally to the transfer roller.

[0073] It is expressly pointed out that all the aforementioned and subsequent intervals include all intermediate intervals and individual values ​​contained therein, and that these intermediate intervals and individual values ​​are to be regarded as essential to the invention, even if these intermediate intervals or individual values ​​are not specifically specified in detail.

[0074] Further features, advantages, and applications of the present invention will become apparent from the following description of exemplary embodiments with reference to the drawing and the drawing itself. All features described and / or illustrated, individually or in any combination, constitute the subject matter of the present invention, irrespective of their compilation in the claims or their cross-reference.

[0076] The Fig. 1 and Fig. Figures 2 each show a transfer roller 1 according to the invention for a mobile transfer unit 2 for transferring bulk material. Mobile transfer units 2 are, for example, in the embodiments according to the Fig. 4 and Fig. 5 shown.

[0077] Mobile turners 2 are preferably movable, particularly for turning bulk material. Preferably, the mobile turner 2 is intended for turning a compost heap 3. In the Fig. In the embodiment shown in Figure 5, a triangular compost heap 3 is provided, which can also be referred to as a triangular heap. This triangular compost heap 3 is first mixed and then rebuilt or stacked, which, within the meaning of the present invention, is understood as "turning". The rebuilding or stacking of the compost heap results in a triangular shape of the compost heap 3 even after the turning process.

[0078] It should be noted, however, that the turning roller 1 or the mobile turner 2 according to the invention can also be used for compost heaps of other shapes other than triangular. Ultimately, the turning roller 1 according to the invention is suitable for turning any bulk material or free-flowing material that is mixed and / or homogenized for the purpose of turning.

[0079] The transfer or recirculation takes place via the transfer roller 1 as the central component or processing component of the mobile transfer unit 2.

[0080] The transfer roller 1 has different functional sections in the axial direction in order to carry out the transfer of the bulk material in a functional and coordinated manner.

[0081] Generally, the transfer roller 1 is rotated when transferring bulk material, specifically in the position shown in Fig. 2. Rotation direction R shown, here counterclockwise.

[0082] As demonstrated in particular by Fig. As can be seen in Figure 1, the transfer roller 1 has a roller body 4 with two transfer areas 26. The transfer of the bulk material takes place in the transfer areas 26, for which a plurality of transfer tools 7 are provided in each of the transfer areas 26.

[0083] A central area 27 with throwing tools 28 is provided between the transfer areas 26. The throwing tools 28 are arranged in several rows 29 and enable or support the homogenization and circulation of the bulk material during the transfer process.

[0084] Between each end face of the roller body 4 and the respective transfer area 26, an end region 30 is provided, wherein engagement tools 31 are arranged in the end region 30. The engagement tools 31 serve in particular to engage or transport the engaged bulk material towards the center or axially inwards along the transfer roller 1 or the roller body 4, starting from the respective end face of the roller body 4.

[0085] The present invention is primarily aimed at modifications or improvements in the conversion area 26 or in the design and alignment of the conversion tools 7 in the conversion area 26.

[0086] Accordingly, the following discussion will primarily focus on the conversion area 26 and the conversion tools 7.

[0087] Therefore, in Fig. 6 a roller body 4 only with conversion areas 26 or with omitted central areas and end areas illustrated in order to clarify the arrangement and design of the conversion area 26 accordingly.

[0088] The transfer tools 7 are part of a tool arrangement 5. This tool arrangement 5 has, in addition to the transfer tool 7, a tool holder 6, wherein an associated transfer tool 7 is received or held on each tool holder 6.

[0089] The conversion tools 7 are arranged or held in a specific orientation relative to the roller body 4 or to its rotor central longitudinal axis 17, as shown below first by reference to Fig. 15 is explained.

[0090] According to the invention, a central transverse axis 16 of the transfer tool 7, which runs through the tool holder 6 away from the tool holder 6, encloses a rotation angle γ between 1° and 30°, more preferably between 3° and 15° and in particular 12 ± 3°, to a rotor central axis 17 of the roller body 4.

[0091] In the illustrated and preferred embodiment, the angle of rotation γ is between 12° and 15°.

[0092] The bulk material is transferred via the transfer tools 7 by adjusting the rotation angle γ relative to the rotor's central longitudinal axis 17. This transfer preferably occurs simultaneously towards the center of the roller body 4, or from the end regions 30 towards the center or the central region 27 of the roller body 4. This process ensures low-wear and gentle handling, thus enabling efficient and sustainable operation of the mobile transfer unit 2 using the transfer unit 1 according to the invention.

[0093] Also in Fig. Figure 15 shows the angles γ and γ2, which are illustrated at one end section of the tool holder 6 or the transfer tool 7 facing the center of the roller body 4 and correspond in value to the rotation angle γ.

[0094] Ultimately, the central transverse axis 16 of the transfer tool 7 is skew to the rotor central longitudinal axis 17 of the roller body 4.

[0095] According to another aspect of the present invention, which is preferably implemented in addition to or as an alternative to the above aspect, the transfer tools 7 are also tilted in the direction of the roller body 4 or its outer surface 11, cf. Fig. 13A or 13B.

[0096] Specifically, it is provided that the front side 8 of the transfer tool 7, facing away from the tool holder 5, includes a tilting angle α of at least 5°, preferably between 5° and 55°, more preferably between 10° and 50°, and in particular between 30° and 40°, to a tangent 14 on the outer surface 11 of the roller body 4, which intersects a central longitudinal axis 13 of the transfer tool 7 at an intersection point 15 on the outer surface 11 of the roller body 4.

[0097] The central longitudinal axis 13 can, in particular, define the central axis and / or pass through the center of gravity, as shown in the Fig. 11 and Fig. Figure 12 illustrates this. The central longitudinal axis 13 can also be an axis of symmetry or an approximate axis of symmetry of the transfer tool 7. In this context, it is understood that the central longitudinal axis 13 does not have to form the exact axis of symmetry, since the transfer tool 7 is not necessarily symmetrical. However, the central longitudinal axis 13 can form an approximate axis of symmetry in the direction of its greatest longitudinal extent. Furthermore, the transfer tool 7 can be elongated, so that the central longitudinal axis 13 is ultimately, in particular, the longitudinal axis of the transfer tool 7 or defines its longitudinal extent. Alternatively, the transfer tool 7 can also have essentially the same longitudinal and lateral extent or a greater lateral extent.

[0098] In the Fig. In the preferred embodiment shown in Figure 11, the central longitudinal axis 13 is designed to run at least substantially parallel to the two side edges or longitudinal edges of the transfer tool 7. The term longitudinal edge can be used synonymously with side edge or longitudinal side. Accordingly, it is preferably designed that the central transverse axis 16 is designed to run at least substantially parallel to the two transverse edges of the transfer tool 7.

[0099] Alternatively or additionally, the tilting in question can also be implemented by a tilting with respect to a tangential plane 10 on the outer surface 11 of the roller body 4, as shown by Fig. 14 is evident.

[0100] The front side 8 of the transfer tool 7, facing away from the tool holder 6, includes a first plane 9 which forms a tilt plane angle β of at least 5°, preferably between 5° and 50°, more preferably between 10° and 40°, and in particular between 30° and 35°, with respect to the tangent plane 10 on the outer surface 11 of the roller body 4, which intersects the first plane 9 in a section line 12 on the outer surface 11 of the roller body 4.

[0101] In the illustrated and preferred embodiment, the rotation angle γ is 12° ± 3° and the tilt angle α or the tilt plane angle β is approximately 30°. Therefore, the tilt angle α and / or the tilt plane angle β are preferably larger than the rotation angle γ.

[0102] The following will be based on the Fig. Sections 7 to 9, as well as 10A and 10B, discuss the design of the tool holder 6 in more detail.

[0103] The tool holder 6 has a lower base section 19 attached to the roller body 4 and an upper mounting section 20 adjoining the base section 19 for the detachable attachment of the transfer tool 7. In the illustrated preferred embodiment, the transfer tool 7 is attached to the mounting section 20 by means of screw connections 18. The nut of the screw connection 18 is located on a side of the mounting section 20 facing away from the front, with a corresponding screw head on the front 8. The screw head is preferably rounded in order to only minimally affect the planar design of the transfer tool 7.

[0104] Based on the Fig. 10A and Fig. Figure 10B, in which the tool holder 6 is shown without the transfer tools 7, also shows that a mounting surface 21 of the mounting section 20 forms an angle between 140° and 179°, preferably between 150° and 175°, with an end face 22 of the base section 19 adjoining the mounting surface 21 downwards. This causes the transfer tool 7 to tilt towards the outer surface 11 of the roller body 4.

[0105] In addition, the tool holder 6 or the fastening section 20 has reinforcing ribs 23 projecting laterally from the fastening surface 21.

[0106] Alternatively or additionally, side webs 24 are provided projecting laterally from the front face 22 of the base section 19.

[0107] In particular, the reinforcing webs 23 and the side webs 24 are firmly connected to each other, preferably welded.

[0108] Preferably, the reinforcing webs 23 are offset from one another such that the mounting surface 21 is offset from the rotor's central longitudinal axis 17. This adjusts or fixes the rotation angle γ accordingly.

[0109] In the preferred embodiment shown, the reinforcing webs 23 taper to a point opposite the mounting surface 21.

[0110] In general, the base section 19 and the fastening section 20 can first be manufactured or provided separately and then joined together, preferably welded.

[0111] Preferably, the base section 19 and / or the fastening section 20 are each designed as profiles open on one side, in particular U-profiles.

[0112] A minimum distance 25 between the upper edge of the transfer tool 7 and the outer surface of the roller body 4 is at least 280 mm, preferably between 280 mm and 320 mm, more preferably between 290 mm and 310 mm, cf. Fig. 1.

[0113] Regarding the design of the transfer tool 7 in general, it is preferably plate-shaped and / or planar. In particular, the transfer tool 7 has a planar or protrusion-free front surface 8, cf. Fig. 11.

[0114] The transfer tool 7 is preferably rectangular or trapezoidal, in particular diamond-shaped.

[0115] Especially in the case of the diamond-shaped design, the upper side of the transfer tool 7 is offset axially inwards towards the center of the transfer roller 1 or the roller body 4 compared to the lower side, as shown in Fig. 6 is shown.

[0116] In general, the transfer tool 7 has a height in the range of 160-200 mm, preferably 170-190 mm, and in particular approximately 180 mm.

[0117] Furthermore, the transfer tool 7 has a width in the range of 180-210 mm, preferably 185-195 mm, in particular approximately 190 mm.

[0118] The thickness of the transfer tool 7 is preferably between 10-20 mm, preferably between 10-15 mm.

[0119] In the corner regions of the transfer tool 7, obtuse and acute angles are preferably formed alternately. The obtuse angles are in the range of 100–110°, preferably in the range of 100–105°. The acute angles are preferably in the range of 70–80°, in particular in the range of 75–80°.

[0120] As especially from Fig. As can be seen from Figure 6, the transfer tools 7 extend along a spiral line that runs at least substantially spirally around the roller body 2. It is possible that several spiral lines are provided for the transfer roller 1 to arrange the transfer tools 7, as is particularly evident from Figure 6. Fig. 6 emerges.

[0121] Furthermore, the Fig. 2, that adjacent transfer tools 7 along a spiral line are arranged at a distance from each other that is at least substantially equal. The distance refers in particular to the center point or center of gravity of the transfer tools 7.

[0122] Preferably, conversion tools 7 are arranged around each turn on the spiral line between 5 and 15, more preferably between 6 and 14, and more preferably between 7 and 12.

[0123] Furthermore, the Fig. 2, that the roller body 4 has on its outer side a repositioning area 26 with repositioning tools 7 arranged in opposing spiral lines, wherein the central area 27 is provided between the repositioning areas 26. In the central area 27, throwing tools 28, in particular designed as throwing vanes, can be arranged.

[0124] In this context, the Fig. 2 further, that the transfer tools 7 are arranged in particular only in the transfer areas 26. The arrangement in the transfer areas 26 can be made in particular along spiral lines. These spiral lines do not then have to extend over the entire length of the transfer roller 1, but in particular only over the length of the transfer areas 26. In particular, the spiral lines of the transfer areas 26 are oriented in opposite directions to each other, preferably symmetrically.

[0125] The height of the throwing tools 28 and / or the engagement tools 31 can in particular be the height of the repositioning tool 7 or less.

[0126] The throwing tools 28 are according to the in the Fig. 1 and Fig. In the preferred embodiment shown in Figure 2, the throwing tools 28 are arranged circumferentially in several rows 29. Preferably, at least two, and preferably three, throwing tools 28 are arranged in each row 29. Due to the orientation of the throwing tools 28, the row 29 can have a shape that is at least substantially curved or angled.

[0127] For example, two outer throwing tools 28 can be arranged relative to a central throwing tool 28 such that the outer throwing tools 28 form an angle of between 120° and 175°, preferably between 140° and 170°, with the central throwing tool 28. The throwing tools 28 can have a lower edge that is at least substantially straight, so that a curved or angled shape of the series 29 results, particularly due to the oblique orientation of adjacent throwing tools 28 relative to each other.

[0128] Furthermore, it is shown that the throwing tools 28 can essentially also be configured as engagement tools 31 and / or be identical to one another. In particular, in this embodiment, a plurality of engagement tools 31 can be arranged in a row 29, preferably between 5 and 30. The throwing tools 28 or the engagement tools 31 can be bent.

[0129] In the Fig. 5 is a mobile transfer unit 2 for transferring bulk material, in particular a compost heap 3, with a vehicle chassis 34 and a transfer roller 1 mounted on the vehicle chassis 34 which is rotatable about an axis of rotation, in particular the rotor central longitudinal axis 17, according to one of the embodiments described above.

[0130] Furthermore, the Fig. 5, that the vehicle chassis 34 has a running gear 36 or is supported by a running gear 36. The running gear 36 can in particular be designed as a tracked running gear or have a track.

[0131] Furthermore, it is shown that the vehicle chassis 34 spans the transfer roller 1 in a bridge-like manner. In particular, the vehicle chassis 34 spans the transfer roller 1 in such a way that a channel 35 for the passage of the bulk material is formed between the vehicle chassis 34 and the transfer roller 1. Such a passage is particularly evident in the Fig. 4 shown in more detail.

[0132] The Fig. Figure 16 illustrates that the throwing tool 28 and / or the engagement tool 31 has a first section 32, which is in particular plate-shaped, and a second section 33, which is in particular plate-like, and angled relative to the first section along an engagement bending edge. The engagement bending edge can be arranged at least parallel to the upper edge of the second section 33 and / or parallel to the lower edge of the first section 32. Preferably, no inclined engagement bending edge is provided.

[0133] The second section 33 can be bent at an angle relative to the first section 32. The angle is particularly between 140° and 170°, preferably between 150° and 160°.

[0134] The throwing tool 28 or the engagement tool 31 is preferably elongated and / or has a length in the range of 280 mm to 300 mm, preferably 280 mm to 190 mm.

[0135] The throwing tool 28 or the engagement tool 31 is preferably designed symmetrically in the longitudinal direction with two opposing second sections 38.

[0136] The second section 33 or the engagement tool 31 preferably has a length in the range of 30-50 mm, preferably from 35 mm to 40 mm.
