Description

Technical Field

[0001] This application relates to the technical field of scraper conveyor equipment for mining, and in particular to a highly adaptable scraper conveyor trough and scraper conveyor. Background Technology

[0002] The scraper conveyor connects to the hydraulic support's pusher cylinder via a pusher lug positioned in the middle of the baffle side of the central trough, enabling the overall propulsion of the scraper conveyor. The pusher lug bears the pushing and lifting forces of the pusher cylinder. The central trough is integrally cast and welded. However, if the width of the hydraulic support is inconsistent with the length of the central trough, the position of the hydraulic support's pusher cylinder and the pusher lug of the central trough will be mismatched, failing to meet the pushing requirements of the working surface.

[0003] Therefore, there is an urgent need for a highly adaptable scraper conveyor trough that can accommodate hydraulic supports of various widths, thereby improving the adaptability and reusability of the scraper conveyor trough. Utility Model Content

[0004] In view of this, it is necessary to provide a highly adaptable scraper conveyor trough and scraper conveyor to solve the problems of insufficient adaptability and low reusability caused by the scraper conveyor trough not being able to meet the requirements of hydraulic supports of various widths in the prior art.

[0005] A highly adaptable scraper conveyor center trough includes:

[0006] The components include a shovel groove 1, a middle plate 2, a bottom plate 3, and a baffle groove 4; the baffle groove 4 is evenly provided with multiple mounting seats 5.

[0007] A sliding lug 6 is detachably and fixedly connected to the mounting base 5 at the target position according to the width of the hydraulic support;

[0008] The mounting base 5 is provided with first stiffening plates 51 on the upper and lower sides, and the sliding ear 6 is detachably and fixedly installed in the first stiffening plate 51.

[0009] Preferably, the mounting base 5 is provided with a positioning hole 52, and the sliding ear 6 is provided with a mounting hole 61; the mounting base 5 and the sliding ear 6 are detachably and fixedly installed in the first stiffening plate 51 by bolts through the positioning hole 52 and the mounting hole 61.

[0010] Preferably, the mounting base 5 is concave and the sliding ear 6 is convex;

[0011] The mounting base 5 has positioning holes 52 on both sides of its protruding portion; the sliding ear 6 has mounting holes 61 on its central protruding portion.

[0012] Preferably, the mounting base 5 located in the middle of the baffle groove 4 has a second rib 53 at both the upper and lower ends of the first rib 51.

[0013] Preferably, the inner wall of the mounting base 5 and the contact area with the sliding ear 6 are provided with a wear-resistant material.

[0014] Preferably, the baffle groove 4 is provided with 5 mounting seats 5.

[0015] Preferably, the mounting base 5 and the baffle groove 4 are integrally formed by casting and welding.

[0016] A scraper conveyor includes a highly adaptable scraper conveyor central trough as described above.

[0017] Compared with the prior art, the beneficial effects of this application are as follows: the aforementioned highly adaptable scraper conveyor center trough can be fixedly connected to the sliding lug on the mounting seat at the target position according to the width of the hydraulic support, greatly improving the applicability and reusability of the center trough. In addition, since the scraper trough side and its mounting seat are integrally cast and welded, the center trough provided by this application can avoid the need for casting and welding multiple sets of center troughs, thus reducing costs.

[0024] To more clearly illustrate the technical solutions of the embodiments of this application, the drawings used in the embodiments will be briefly introduced below. Obviously, the drawings described below are some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0025] like Figure 1 As shown, scraper conveyors are commonly used conveying equipment in industries such as coal mines. The central trough, as a key component, bears the responsibility of transporting the scraper chain and materials. In existing designs, the length of the central trough matches the width of the hydraulic support; the pusher lugs are often designed in the middle of the baffle trough side, subjected to the enormous pushing and lifting forces from the hydraulic support. Traditional central trough designs often only have a single set of pusher lugs. However, if the width of the hydraulic support is inconsistent with the length of the central trough, the position of the pusher cylinder of the hydraulic support and the pusher lug of the central trough will not match, failing to meet the pushing requirements of the working face. If the central trough is to be additionally cast and welded or the hydraulic support replaced, it will increase costs and be time-consuming and labor-intensive.

[0026] To address the aforementioned issues, this application provides a highly adaptable scraper conveyor center trough. Please refer to [link / reference]. Figures 2 to 5 , Figure 2 This is a schematic diagram of the overall structure of the middle trough of the scraper conveyor provided in the embodiment of this application; Figure 3 This is a schematic diagram of the disassembled state of the middle trough pusher lug of the scraper conveyor provided in the embodiment of this application; Figure 4 This is a schematic diagram of the installation state of the middle trough push lug of the scraper conveyor provided in the embodiment of this application; Figure 5 This is a schematic diagram of the overall structure of the middle trough of a scraper conveyor provided in another embodiment of this application.

[0027] The highly adaptable scraper conveyor's central trough includes: a scraper trough side 1, a middle plate 2, a bottom plate 3, and a baffle trough side 4; the baffle trough side 4 is evenly provided with multiple mounting seats 5; a pusher ear 6 is detachably and fixedly connected to the mounting seat 5 at the target position according to the width of the hydraulic support; the upper and lower sides of the mounting seat 5 are provided with first stiffening plates 51, and the pusher ear 6 is detachably and fixedly installed in the first stiffening plates 51.

[0028] The baffle groove and mounting base are integrally cast and welded. The multiple mounting bases not only serve to install the sliding lugs but also act as reinforcing ribs on the surface of the baffle groove, greatly enhancing its structural strength. The first stiffening plates 51 on the upper and lower sides of the mounting base 5 not only fix and support the sliding lugs after installation, enhancing the overall strength and durability of the mounting base and the central groove, but also act as limiting elements during the installation of the sliding lugs 6, improving the efficiency of installation and other preparatory work.

[0029] Multiple mounting seats 5 are evenly arranged on the baffle groove. The specific number can be adjusted according to actual needs, but must be determined before casting and welding. For example, there are 5 mounting seats on each baffle groove to ensure sufficient fixing points to accommodate different hydraulic support widths. Furthermore, since the baffle groove and mounting seats are integrally cast and welded, for example, the baffle groove and baffle groove are cast using ZG30SiMn. Too dense a number of mounting seats will increase the casting difficulty and the overall weight of the baffle groove, hindering production activities. Too sparse a number of mounting seats will not be able to accommodate hydraulic supports of various widths. Therefore, in this embodiment, the preferred number of mounting seats is 5.

[0030] Furthermore, in some embodiments, the mounting base is concave, and the sliding ear is convex. Positioning holes 52 are provided on the protruding portions on both sides of the mounting base, and mounting holes 61 are provided on the protruding portions of the sliding ear. The mounting base 5 and the sliding ear 6 are detachably and securely connected by bolts through the positioning holes 52 and the mounting holes 61. The positioning holes on the mounting base match the mounting holes on the sliding ear, ensuring the accuracy and stability of the connection. Bolts pass through these two holes to firmly join the two together, forming a reliable connection.

[0031] The concave-convex structure of the mounting base and the sliding lug not only enhances the stability of the mechanical interface but also makes the installation and disassembly process simpler and faster. The protruding parts on both sides of the mounting base are provided with positioning holes, and the protruding part in the middle of the sliding lug is provided with corresponding mounting holes, ensuring that the sliding lug can be accurately embedded into the mounting base and firmly fixed together with bolts.

[0032] In addition, the detachable fixed connection is achieved by fasteners such as bolts passing through these two holes, which not only ensures the accuracy, stability and ease of maintenance of the connection, but also allows for quick removal of the push lug when not in use, which can reduce the overall weight of the central slot without affecting the basic function of the central slot.

[0033] Furthermore, such as Figure 5 As shown, second stiffeners 53 are provided at both the upper and lower ends of the first stiffener 51 of the mounting seat 5 located in the middle of the baffle groove 4. Since the mounting seat 5 located in the middle of the baffle groove 4 is the most commonly used mounting seat 5, second stiffeners 53 are provided at both the upper and lower ends of the first stiffener of this mounting seat to enhance its structural strength and durability. The second stiffeners 53 effectively enhance the strength, stability, and durability of the mounting seat during operation. Furthermore, the mounting seat 5 located in the middle of the baffle groove 4 can be thickened to further enhance its strength.

[0034] Additionally, it should be noted that in this embodiment, the second rib is only provided on the mounting seat located in the middle of the baffle groove. This is to avoid increasing the overall weight of the middle groove by providing too many second ribs. In practice, second ribs can be provided on mounting seats at suitable locations as needed.

[0035] Furthermore, in some embodiments, the inner wall of the mounting base 5, especially at the contact point with the sliding lug 6, is provided with a wear-resistant material. The wear-resistant material at the contact point between the inner wall of the mounting base and the sliding lug can be a high-performance material such as a polymer or ceramic coating. These materials are not only wear-resistant but also have good self-lubricating properties, reducing friction and maintenance frequency. This can effectively reduce the high costs and time wasted due to wear on the central groove (mounting base) or replacement of the hydraulic support.

[0036] Meanwhile, if the push-pull ear 6 is worn, only the push-pull ear needs to be replaced, which reduces costs and shortens the repair and replacement time.

[0037] Based on the same inventive concept, this application also provides a scraper conveyor, which includes the aforementioned highly adaptable scraper conveyor central trough. For a detailed explanation of the principle, please refer to the description of the highly adaptable scraper conveyor central trough above; it will not be repeated in this embodiment.

[0038] In summary, the highly adaptable scraper conveyor center trough provided in this application allows users to flexibly adjust the position and number of the sliding ears according to specific site conditions, ensuring the center trough perfectly adapts to hydraulic supports of various widths, thus improving the overall applicability and working efficiency of the equipment. Simultaneously, the multiple mounting seats themselves can also serve as reinforcing ribs to enhance the structural strength of the baffle trough sides. Based on the adjustable design of the mounting seats and sliding ears, frequent replacement of the center trough or hydraulic supports is no longer necessary, reducing material consumption and labor input, and lowering operating costs. The detachable design makes installation and disassembly simple and quick, significantly shortening preparation time.
