Description

Technical Field

[0001] This invention generally relates to a screen attachment system. In particular, but not exclusively, this invention relates to a screen attachment system for mobile mineral material processing equipment. Background Technology

[0002] This section provides useful background information, but does not acknowledge that any technology described herein represents existing technology.

[0003] Different types of sieves are supplied for use in various mobile mineral processing equipment. Specific installation work may be required to attach a given sieve model to a given mineral processing equipment. Therefore, attaching a desired sieve model to a currently used mineral processing equipment model can be time-consuming and labor-intensive.

[0004] US 2003 / 0146315 A1 discloses a sieve assembly, and WO 2006 / 051165 A1 discloses a frame and multi-purpose fastening device for a movable processing apparatus for mineral materials. Summary of the Invention

[0005] The aim is to facilitate the equipping of mineral material processing equipment with different screens.

[0006] The appended claims define the scope of protection. Any examples and technical descriptions of devices, products, and / or methods not covered by the claims in the specification and / or drawings are not presented as embodiments of the invention, but as background art or examples to aid in understanding the invention.

[0007] According to a first exemplary aspect, a system is provided for equipping a mobile mineral material processing device with a screening module, comprising:

[0008] An elongated connecting base having a first end and a second end in the longitudinal direction, the connecting base comprising:

[0009] The first adapter, located at the first end, is detachably attached to the screen module and is configured to detachably attach the connecting base to the mineral processing equipment via a pivot attachment in the mounting orientation.

[0010] a second adapter spaced apart from the first end, removably attachable to the screen module, and configured to removably attach to the coupling base and form an actuator attachment to the mineral material processing plant for lifting the screen module to a use orientation about the pivotal attachment; and

[0011] a second conveyor base following the first conveyor base in the longitudinal direction for supporting a second outlet conveyor;

[0012] wherein the first conveyor base and the second conveyor base define planes that differ by a vertical angle;

[0013] wherein the first adapter comprises a first connector for coupling with a first connector counterpart of the mineral material processing plant;

[0014] wherein the first connector is configured to allow coupling of the screen module with the mineral material processing plant by laterally moving the mineral material processing plant to engage the first connector with the first connector counterpart.

[0015] Allowing the screen module to be connected with the mineral material processing plant by laterally moving the mineral material processing plant to engage with the screen module can simplify attachment of the screen module with the mineral material processing plant.

[0016] The system can comprise different or adaptable first adapters for two or more different screen modules having different sizes or shapes. The first adapters can be configured to attach to standard beams of the frame of the screen modules by shape locking and / or friction locking.

[0017] The system can comprise different or adaptable second adapters for two or more different screen modules having different sizes or shapes. The second adapters can be configured to attach to standard beams of the frame of the screen modules by shape locking and / or friction locking.

[0018] With the different or adaptable first adapters and / or second adapters, the system can facilitate attachment of different models of screen modules to the mineral material processing plant.

[0019] By the shape locking and / or friction locking of the first adapters and / or second adapters, the screen modules can be attached to the frame of the screen modules of different manufacturers without compromising the strength of the frame (e.g. by welding or drilling).

[0020] The second adapter can comprise a second connector. The frame of the mobile mineral material processing plant can comprise a second counterpart. The second connector can be configured to allow a locking coupling when the second counterpart is engaged with the second connector. The second connector can be configured to automatically lock the coupling when the second counterpart is engaged with the second connector.

[0021] The locking can secure the coupling to avoid accidental or malicious detachment of the screen module from the mineral material processing plant. By automatically locking the coupling, the locking can be made more reliable and / or manual operations can be reduced.

[0022] The screen module can comprise a first end. The first adapter can be configured to support the first end. The second adapter can be configured to allow lifting of a second end of the screen module. The second end of the screen module can be located opposite the first end of the screen module.

[0023] The first adapter can comprise a first connector configured to couple with a first counterpart of a frame of the mineral material processing plant. The first connector can be configured to enable a guided coupling. The first connector itself can comprise a guide connector. The guide connector can comprise a slide-in connector. The slide-in connector can comprise an outwardly opening guide configured to receive a connector receptacle. Alternatively, the slide-in connector can comprise a connector receptacle for entering an outwardly opening guide. The outwardly opening guide can open in a vertical direction. Alternatively or additionally, the outwardly opening guide can open in a horizontal direction.

[0024] The outwardly opening guide can facilitate alignment of the guide and the receptacle, thereby facilitating equipping the mineral material processing plant with the screen module.

[0025] The system can further comprise a screen module ground support. The screen module ground support can allow placing the screen module freely on the ground without the need to prepare a platform for the screen module.

[0026] The screen module ground support can be configured to be attached to the frame of the screen module.

[0027] The screen module ground support can be configured to align the first connector with the first counterpart in the mineral material processing plant. In this case, the screen module can be coupled by moving the mineral material processing plant. Due to the alignment, the first connector can then be coupled with the first counterpart while the screen module is placed on the ground by the screen module ground support. The need for jacking or lifting equipment, or the use of one or more ramps or other temporary structures can be avoided. The coupling can be done by one person.

[0028] By simplifying the coupling of the screen module to the mobile mineral material processing plant, switching of the screen module can also become practical, such that, for example, the screen can be more effectively adapted to changes in input mineral material or desired screened product.

[0029] The frame of the screen module can include a first sub-frame configured to support the screen, and a second sub-frame configured to support a second conveyor below the screen. The frame of the screen module can include one or more links configured to detachably couple the first sub-frame and the second sub-frame. The one or more links can include an actuator holder configured to attach to the first sub-frame and the second sub-frame. The link alone can prevent the first sub-frame and the second sub-frame from separating.

[0030] The screen module ground support can include a link member attached to the first sub-frame or the second sub-frame. The screen module ground support can include a separable component detachably attached to the link member. The link member can be formed of a tubular component.

[0031] The separable component can include one or more first rest members for resting the first section of the screen module against the ground. The first rest member can include a first body configured to support the frame to the ground. The first body can include a tubular member, such as a tube. The first section can be closer to a first end of the screen module than to a second end of the screen module.

[0032] The separable component can include one or more second rest members for resting the second section of the screen module against the ground. The second rest member can include a second body configured to support the frame to the ground. The second body can include a tubular member, such as a tube. The second section can be closer to a second end of the screen module than to a first end of the screen module.

[0033] The first rest member and the second rest member can be releasably attachable to the coupling base. The releasable attachability to the coupling base can enable the first rest member and the second member to be releasably attached to screen modules having different sizes at different spacings. The first rest member and the second rest member can be configured to define a footprint about a center of mass of the screen module, so as to stabilize the screen module ground support when not coupled to the mineral material processing plant.

[0034] The separable component can comprise a ground plate configured to abut the ground. The ground plate can be integrally formed with, or assembled as a permanent component of, the first and second placement members. The ground plate can be equipped with a slot-in member configured to connect with the first or second body.

[0035] The slot-in member can enable the ground plate to be quickly and simply attached to the screen module ground support. The system can comprise a transport carriage comprising a slot-in member configured to fit into the first and second bodies. The transport carriage can be configured to act as a loading track for loading the screen onto a transport platform. The transport platform can be on a truck or a trailer.

[0036] According to a second example aspect, there is provided a mobile mineral material processing plant comprising the system of the first example aspect for equipping the mobile mineral material processing plant with a screen module.

[0037] According to a third example aspect, there is provided a coupling system comprising:

[0038] an elongate coupling base comprising a first adapter and a second adapter configured to detachably attach the screen module, the one or more outlet conveyors together, and to detachably attach the screen module and the one or more outlet conveyors to the mobile mineral material processing plant;

[0039] wherein the first adapter is configured to be pivotably coupled to the mineral material processing plant when the mineral material processing plant is moved laterally to engage with the first connector of the first adapter; and

[0040] the second adapter is configured to allow the actuator to lift the screen module with the coupling base such that the screen module is pivoted about the pivotable coupling from the ground to an inclined operating configuration.

[0041] The coupling base can be angled to horizontally align the tailings conveyor in the inclined operating configuration.

[0057] In the following description, like reference characters designate like elements or steps.

[0058] Various embodiments have been presented. It should be understood that the words comprises, comprises, and comprises, as used in this document, are used as open-ended terms that mean "including but not limited to."

[0059] The foregoing description has provided by way of non-limiting examples of particular implementations and embodiments a full and informative description of the best mode contemplated by the inventors of carrying out the present application. It is however clear to a person skilled in the art that the present application is not limited to embodiments as herein described but can be carried out in other embodiments using equivalent means, or in different combinations of the described features, without departing from the scope of the application.

[0060] Furthermore, some of the features of the previously disclosed exemplary embodiments can be used to advantage without the corresponding use of other features. As such, the foregoing description should be considered as merely illustrative of the principles of the present application, and not in limitation thereof. Hence, the scope of the present application is by no means limited to the foregoing descriptions but is only limited by the appended patent claims.

[0061] Figure 1 A system is shown comprising a mobile mineral material processing plant 100, a screen module 110, and a coupling base 120 for supporting the screen module and coupling the screen module with the mobile mineral material processing plant, and for supporting and coupling an outlet conveyor (e.g. a first outlet conveyor 130 and a second outlet conveyor 132).

[0062] The mobile mineral material processing plant 100 comprises a frame 102, a track 104 for self-propelling, a body arm 106 formed by the frame, a first connector counterpart 108, and a second connector counterpart 109. The first connector counterpart 108 is e.g. a shaft attached to the frame 102. The second connector counterpart 109 is e.g. a recess or vertical groove formed on a top surface of the body arm 106. The body arm 106 can be configured to suspend the screen module 110 at a lateral distance from the first connector counterpart 108 by means of the second connector counterpart 109.

[0063] The screen module 110 comprises a plurality of screens 112.

[0064] The coupling base 120 comprises a first conveyor base 121 extending a first length from a first end for supporting the first outlet conveyor 130, and a second conveyor base 122 following the first conveyor base 121 in a longitudinal direction for supporting the second outlet conveyor 132. The coupling base 120 further comprises a first adapter 124, and in the first adapter 124 comprises a first connector 125 for coupling with the first connector counterpart 108. The first adapter 124 is detachably attached to the first conveyor base 121. In an alternative embodiment, the first adapter partly or entirely forms the first conveyor base 121.

[0065] The coupling base 120 also includes a second adapter 127 having a second connector 128 for coupling with the second connector counterpart 109. In an embodiment, the coupling base 120 also includes a plurality of legs 129 for free-standing the screen module 110 on the ground at the first section SI closer to the first end of the screen module 110 and at the second section S2 through the coupling base 120.

[0066] In Figure 1 embodiments, there can be only one screen deck formed of one or more screens, or there can be more screen decks.

[0067] Figure 2 a more detailed view of a portion of Figure 1 Figure 3 a more detailed view of a portion of Figure 1 Figure 2 and Figure 3 how the first connector 125 and the first connector counterpart 108 engage with each other when the mobile mineral material processing plant 100 and the screen module 110 are coupled together using the coupling base 120. Figure 2 and Figure 3 It is also shown that the first connector 125 has a conical mouth that opens outward to facilitate coupling. It will be appreciated that the implementation of the coupling is freely modifiable: for example, one of the two coupling components can have a spherical or barrel surface. Likewise, the guiding shape for facilitating the coupling can be made up of either or both sides of the coupling. Furthermore, although two or more first connectors 125 and first connector counterparts 108 can be provided, in an embodiment, there is only one first connector and first connector counterpart 108, such that the screen module can be suspended from three points.

[0068] Figure 4 a side view of the mobile mineral material processing plant and the screen module when coupled together. In this configuration, the first connector counterpart 108 is coupled with the first connector 125 through a pivotal attachment, such that the screen module 110 can be lifted upward by pivoting about the first connector 125.

[0069] Figure 4 ​​The system further comprises an actuator 410 having a first end 412 for coupling with the second adapter 127 and a second end 414 for coupling with the frame 102, or more precisely with the body arm 106, of the mobile mineral material processing plant 100. The actuator 410 is for example a hydraulic actuator. The actuator 410 can receive its power from the screen module 110 or from the mobile mineral material processing plant 100. In an embodiment, the actuator remains pivotably connected with one of the mineral material processing plant 100 and the screen module 110 from which the actuator 410 receives power. The screen module 110 can be flexibly supported on the coupling base 120 by for example springs (not shown) so that the screen of the screen module 110 can vibrate without excessive use of energy to vibrate and (cause) structural fatigue of the second outlet conveyor 132. The coupling base 120, the first adapter 124 and the second adapter 127 together form a suspension that suspends the screen module 110 on the mobile mineral material processing plant 100. Figure 4 Also shown is a first outlet conveyor 130 comprised by the screen module 110. In Figure 4 The first outlet conveyor 130 is in this embodiment supported by the coupling base 120 between the screen module 110 and the mobile mineral material processing plant 100.

[0070] In an embodiment, the mineral material processing plant 100 and the screen module 110 are configured to be attached in an installation orientation. Advantageously, the legs 129, the first and second connectors 125, 128 and the connector pairs 108, 109 are positioned so that the installation orientation is created when the screen module 110 is placed on a horizontal ground surface by the coupling base 120. In an embodiment, the first connector pair 108 is configured to allow coupling of the screen module 110 with the mineral material processing plant 100 by driving or towing the mobile mineral material processing plant 100 to engage with the first connector 125 of the screen module 110.

[0071] Figure 5 The mobile mineral material processing plant 100 is shown with the screen module 110 in a use orientation, wherein the screen module 110 has been coupled with the mobile mineral material processing plant 100 using the coupling base, pivoted upwards around the first connector 125 using the actuator 410 and locked in place by the second connector 128.

[0072] The first and second conveyor bases 121, 122 define planes that differ by a vertical angle a. The vertical angle a can be such that the first conveyor base 121 is horizontal when seen from the longitudinal direction of the coupling base 120 when the mineral material processing plant 100 is processing mineral material with the screen module 110.

[0073] Figure 6 a more detailed view of a part of Figure 5 The second end of the actuator 410 is configured to engage with a receiver 610 arranged in the frame 102 or body arm 106 of the mineral material processing plant 100. A coupling pin or bushing 620 is inserted through the ring in the second end 414 of the actuator 410 to form an actuating attachment with the receiver 610. This attachment allows the screen module 110 to be lifted by means of the actuator 410 about the pivotal attachment through the coupling base to a use position as shown in Figure 5

[0074] In Figure 6 there are separate and spaced apart components for attaching the actuator 410 and for coupling the screen module 110 with the second connector 128. In another embodiment, however, these functions are combined wholly or partially. For example, Figure 6 The receiver 610 of

[0075] In an embodiment, the second connector 128 is configured to allow a locking coupling. For this, for example, a locking pin or padlock can be used. In case the receiver 610 is also used as the second connector counterpart 109, the locking can be implemented by forming a self-locking form that prevents falling back. In this case, the locking can be released so that by operating the actuator again, the second connector 128 is moved upwards away from the receiver 610 and the automatic mechanism bypasses the locking or the locking is bypassed manually. For example, the receiver can be blocked by a bypass object of suitable shape that guides the connector past the receiver. Such a bypass object can be hingedly or slidingly connected to the screen module to avoid losing the bypass object and to improve safety. The bypass object can be operated by actuation of the actuator 410 or manually. The locking is configured to secure the coupling to avoid the screen module 110, or more precisely the coupling base 120 carrying the screen module 110, from unintentionally or maliciously detaching from the mineral material processing plant 100. By automatically locking the coupling, the locking can be made more reliable and / or manual operation can be reduced.

[0076] Figure 7 a part of the coupling base 120 and the second outlet conveyor 132 of Figure 1 The coupling base 120 comprises two pairs of connection members 710 attached, for example by welding or bolting, therein. The connection members 710 are made, for example, of relatively short tubes or rings. The connection members 710 are configured to receive​Figure 9 The transport carriage (platform) 900 or Figure 13 The separately formed slotted members 920 of the leg 129 are also shown. The connecting members also form, in whole or in part, the first conveyor base 121.

[0077] Figure 8 A partial screen module assembly of an example embodiment is shown, along with the coupling base 120 including the first adapter 124 and the first connector 125 with winching or tow ring 810. Figure 8 How the second adapter 127 facilitates attachment of the screen module 110 and the coupling base 120 together and support of the actuator 410 is shown. Figure 8 How the second adapter 127 functions as an actuator holder is also shown. In an embodiment, the actuator holder has a slot between two plates forming the body of the second adapter 127. The slot can be formed with a hole that aligns with a ring located at one end of the actuator 410.

[0078] Figure 9 A transport carriage 900 of an example embodiment is shown, as mentioned in connection with Figure 7 the description. In addition to the previously mentioned slotted members 920, the transport carriage includes a transport beam 910 to enable sliding of the supported screen module onto the transport platform and back using a winch pulled from the winching or tow ring 810. The ring 810 can also be used to tow the screen module in the field, with the transport beam 910 serving as a sledage. The transport carriage also includes a cross structure for supporting the beam into place, here formed by two cross bars 930. The transport carriage 900 can be attached to the connecting members 710 simply by lifting and then lowering the screen module, so that the connecting members 710 align and connect with the slotted members 920. In some embodiments, such lifting can be facilitated using the actuator 410 (preferably at least one on each side). If space is too small, a small sand or soil pile can be facilitated (formed) by driving or towing the mineral material handling equipment thereon, in order to gain more space underneath. The transport carriage 900 can be locked into place to the screen module, for example using a pin slotted through the aligned holes of the connecting members 710 and the slotted members 920.

[0079] Figure 10 A partial screen module assembly of Figure 9 is shown when combined with the transport carriage for transport of Figure 8 .

[0080] Figure 11A first adapter 124, 124' is shown for two different exemplary embodiments for adapting different screen modules and mobile mineral material processing plant together. By forming a suitable vertical and horizontal offset for the first connector 125 (as shown), a desired alignment can be provided for the first end of the screen module. Figure 8

[0081] Figure 12 A second adapter 127, 127' is shown for two different exemplary embodiments. Similar to the first adapter 124 and 124', different screen modules and mobile mineral material processing plant can be adapted by properly aligning the first end of the screen module, the second adapter 127, 127' is capable of properly aligning the second end by supporting the screen module 110 at a desired height relative to the second outlet conveyor 132.
