Description

Technical Field

[0001] This utility model relates to the field of coarse crushing equipment technology, and in particular to a modular, easily disassembled support structure and coarse crushing equipment. Background Technology

[0002] In mining machinery crushing and screening production lines, coarse crushing, as the first stage of crushing, is responsible for the initial crushing of large pieces of ore and other raw materials. Coarse crushing equipment mainly includes a steel structure, feed hopper, feeder, crusher, multiple discharge hoppers, maintenance platform, and ladder components. Traditional coarse crushing equipment is typically an integral structure, often welded on-site. The connections between components are complex, requiring a professional installation team and a long installation time. It is difficult to manufacture, prone to deformation and poor quality, resulting in low installation efficiency and severely impacting the production line construction progress. During later maintenance, due to the high integration and interrelationship of components, replacing one part may require disassembling a large number of other parts, or even replacing the entire unit, leading to low maintenance efficiency and high costs. Furthermore, the welded integral structure of this coarse crushing equipment makes secondary transportation inconvenient, especially in remote mines or locations with complex terrain, resulting in high transportation costs and difficulties, and a cumbersome installation process. In addition, the sand and gravel raw materials transported from the raw material silo cause continuous and severe wear on the inner wall of the feed hopper, significantly shortening the overall service life of the coarse crushing equipment and resulting in high maintenance and replacement costs.

[0003] With the expansion of mining scale and the increasing demands for production efficiency, coarse crushing equipment needs to possess better flexibility, maintainability, adaptability, and service life. Therefore, there is an urgent need in this field for a new structure for coarse crushing equipment that is both easy to transport and quick to assemble and disassemble, and easy to maintain. Utility Model Content

[0004] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a modular and easy-to-disassemble support structure and coarse crushing equipment, so as to solve the problems of inconvenient quick disassembly and assembly and high maintenance costs of the existing coarse crushing equipment.

[0005] The objective of this utility model is achieved through the following technical solution: This utility model provides a modular and easily disassembled support structure, including a crusher support frame, a feeder support frame, a feed hopper, a crusher discharge hopper, and a feeder discharge hopper. The crusher support frame has a crusher mounting position for installing the crusher, and the feeder support frame has a feeder mounting position for installing the feeder. The crusher support frame and the feeder support frame are detachably connected. The feed hopper is detachably connected to the feeder support frame and located above the feeder mounting position. The crusher discharge hopper is connected to the crusher support frame and located below the crusher mounting position. The feeder discharge hopper is detachably connected to the feeder support frame and located below the feeder mounting position.

[0006] Furthermore, the height of the crusher support frame is lower than the height of the feeder support frame.

[0007] Furthermore, the feed hopper is an overall conical structure with a wide opening and narrow bottom.

[0008] Furthermore, the feed hopper is provided with a reinforcing crossbeam, which is connected between two opposing inner walls of the feed hopper.

[0009] Furthermore, the feeder hopper has one inlet and two outlets, both of which are connected to the inlet.

[0010] Furthermore, the feeder discharge hopper is equipped with a tilting baffle, an adjusting handle, and an adjusting track. The tilting baffle is rotatably connected inside the feeder discharge hopper and located at the intersection of the two discharge ports. One end of the adjusting handle is fixed to the rotating shaft of the tilting baffle, and the other end of the adjusting handle is slidably connected to the adjusting track.

[0011] Furthermore, the working surfaces of the feed hopper, the crusher discharge hopper, and the feeder discharge hopper are all equipped with detachable wear-resistant plates.

[0012] Furthermore, the support structure includes a maintenance platform and a ladder assembly. The maintenance platform is detachably connected to the crusher support frame and located above the crusher mounting position. The ladder assembly is detachably connected to the crusher support frame and the feeder support frame.

[0013] Furthermore, the support structure includes a magnetic separator support frame for mounting the magnetic separator, the magnetic separator support frame being detachably connected to the crusher support frame and located at the end of the crusher support frame away from the feeder support frame.

[0014] This application also provides a coarse crushing device, including a crusher, a feeder, and a support structure as described above. The crusher is detachably installed in the crusher mounting position of the crusher support frame, and the feeder is detachably installed in the feeder mounting position of the feeder support frame.

[0015] The beneficial effects of this utility model are as follows: By adopting a modular design for the main support body, it is divided into multiple modules such as the crusher support frame, feeder support frame, feed hopper, crusher discharge hopper, and feeder discharge hopper. The larger modules are detachably connected. Each module is prefabricated in the factory, with standardized interfaces and dimensions, high versatility, and can achieve mass production in the factory. This greatly improves the efficiency of manufacturing, transportation, and on-site assembly, and facilitates packaging, transportation, and on-site assembly. During on-site assembly, the various modules of the coarse crushing equipment can be quickly assembled together using bolts, pins, and other connecting parts, without the need for complicated welding and debugging processes. This ensures a firm connection and easy disassembly, making it suitable for project relocation. For secondary transport, it can be disassembled into smaller units, which is very convenient to disassemble and assemble, easy to operate, and has a lower overall cost. This solves the technical problems of existing integral welded coarse crushing steel structure main bodies, such as troublesome on-site welding and fabrication, difficult secondary transport, long construction period, and difficult maintenance.

Detailed Implementation

[0022] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the following detailed description, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation methods, structures, features, and effects of the modular, easily detachable support structure and coarse crushing equipment proposed according to this utility model: Figure 1 This is a three-dimensional structural diagram of the coarse crushing equipment in this utility model.

[0023] like Figures 1 to 5 As shown, the present invention provides a modular and easily detachable support structure, including a crusher support frame 10, a feeder support frame 20, a feed hopper 30, a crusher discharge hopper 40, and a feeder discharge hopper 50. The crusher support frame 10 has a crusher mounting position for installing a crusher 300, and the feeder support frame 20 has a feeder mounting position for installing a feeder 200. The crusher support frame 10 and the feeder support frame 20 are detachably connected. The feed hopper 30 is detachably connected to the feeder support frame 20 and is located above the feeder mounting position. The crusher discharge hopper 40 is connected to the crusher support frame 10 and is located below the crusher mounting position. The feeder discharge hopper 50 is detachably connected to the feeder support frame 20 and is located below the feeder mounting position. Optionally, some components of the crusher discharge hopper 40 are detachably connected to the crusher support frame 10, while other components are fixedly connected to the crusher support frame 10. For example, the left plate of the crusher discharge hopper 40 is detachably connected, while the front and rear plates of the crusher discharge hopper 40 are fixedly connected. The side wall of the crusher discharge hopper 40 is equipped with mounting holes, allowing for easy adjustment of the discharge opening size by adding baffles of different sizes. Simultaneously, the feeder discharge hopper 50 is designed with a detachable structure, facilitating the replacement of discharge hoppers with different outlet sizes. This allows for easy replacement of the discharge opening sizes of both the crusher discharge hopper 40 and the feeder discharge hopper 50, thus enabling both to be adapted to belt conveyors of different widths. The interface flange of the feeder discharge hopper 50 can be made circular, allowing for adjustment of the discharge direction by rotation.

[0024] The crusher support frame 10, the feeder support frame 20, the feed hopper 30, the crusher discharge hopper 40, and the feeder support frame 20 can all be quickly assembled together using bolts, pins, and other connecting parts, without the need for complex welding and debugging processes. This ensures a firm connection and easy disassembly. The crusher support frame 10 adopts an integral frame, with the columns, crossbeams, and longitudinal beams welded and painted in-house. This provides the stability of an integral welded structure, and its dimensions fully meet transportation requirements. It can then be quickly assembled with other components on-site using fastening connectors. Optionally, the crusher support frame 10 integrates the function of the crusher discharge hopper 40. The baffles on both sides of the crusher discharge hopper 40 are integrated with the crusher support frame 10 in-house, with only one side baffle of the crusher discharge hopper 40 requiring on-site assembly.

[0025] In this embodiment, the height of the crusher support frame 10 is lower than the height of the feeder support frame 20, so that there is a certain height difference between the feeder 200 and the crusher 300, which makes it easier for the material in the feeder 200 to fall into the crusher 300 for crushing by gravity.

[0026] Furthermore, the feed hopper 30 features a wide-mouth, narrow-bottom conical structure to ensure smooth flow of sand and gravel from the raw material silo into the feed hopper 30. A reinforcing crossbeam 31 is installed inside the feed hopper 30, connecting two opposing inner walls. Optionally, the reinforcing crossbeam 31 is positioned near the tail end (discharge position) of the feed hopper 30 to improve its stability. Pre-drilled bolt holes on the upper edge of the feed hopper 30 allow for the subsequent installation of a heightening baffle device to accommodate larger sand and gravel volumes.

[0027] In this embodiment, as Figure 5 As shown, the feeder discharge hopper 50 has one inlet 501 and two outlets 502. Both outlets 502 are connected to the inlet 501, forming a "one inlet, two outlets" structural design. Optionally, the feeder discharge hopper 50 is equipped with a tilting baffle 51, an adjusting handle 52, and an adjusting track 53. The tilting baffle 51 is rotatably connected inside the feeder discharge hopper 50 and located at the intersection of the two outlets 502. One end of the adjusting handle 52 is fixed to the rotating shaft of the tilting baffle 51, and the other end of the adjusting handle 52 is slidably connected to the adjusting track 53. The adjusting track 53 has an arc-shaped sliding hole, and the end of the adjusting handle 52 away from the rotating shaft of the tilting baffle 51 is bolted to the sliding hole. When the angle of the flip baffle 51 needs to be adjusted, the adjustment handle 52 is rotated and the flip baffle 51 is rotated. When it is rotated to the required angle, it is fixed to the adjustment track 53 by bolts. The flip baffle 51 remains stable under its own weight and the fixing of the bolts, realizing the diversion of sand and gravel of different particle sizes, and is then transported by belt conveyor to the designated position or the next module.

[0028] Furthermore, the working surfaces of the feed hopper 30, crusher discharge hopper 40, and feeder discharge hopper 50 are all equipped with detachable wear-resistant plates 90. This significantly extends the service life of the sand and gravel inflow area. The wear-resistant plates 90 are detachable, for example, installed on the working surfaces of the feed hopper 30, crusher discharge hopper 40, and feeder discharge hopper 50 with screws. Therefore, when the wear-resistant plates 90 are severely worn, only the plates themselves need to be replaced. The main steel structure is reusable, thus multiplying the overall service life of the feed hopper 30, crusher discharge hopper 40, and feeder discharge hopper 50. The wear-resistant plates 90 can be made of high-strength wear-resistant steel plates such as NM400 and Hardox450. Multiple wear-resistant plates 90 form wear-resistant component units, making maintenance and replacement quick and convenient.

[0029] In this embodiment, the support structure includes a maintenance platform 60 and a ladder assembly 70. The maintenance platform 60 is detachably connected to the crusher support frame 10 and is located above the crusher installation position. The support legs of the maintenance platform 60 are mounted on the crusher support frame 10, enabling safe daily maintenance of the area above the crusher 300. The ladder assembly 70 is detachably connected to the crusher support frame 10 and the feeder support frame 20. The ladder assembly 70 is provided at the step between the crusher support frame 10 and the ground, and also at the step between the crusher support frame 10 and the feeder support frame 20. The ladder assembly 70 has an appropriate angle, and the step panel is made of checkered plate for anti-slip purposes, making it easier for workers to climb onto the crusher support frame 10 and the feeder support frame 20.

[0030] In this embodiment, the support structure includes a magnetic separator support frame 80 for mounting the magnetic separator 400. The magnetic separator support frame 80 is detachably connected to the crusher support frame 10 and is located at the end of the crusher support frame 10 away from the feeder support frame 20. The magnetic separator support frame 80 adopts a "7-shaped" structural design, suspending the magnetic separator 400 (iron remover) below the crossbeam and vertically distributed with the conveyor belt (which runs from the crusher discharge hopper 40, passes under the magnetic separator 400, and extends to the next processing module). This design provides good iron removal and significantly improves space utilization. Optionally, the magnetic separator support frame 80 can be mounted on the right side of the crusher support frame 10 (…). Figure 2 The two support legs of the magnetic separator support frame 80 are integrated for easy disassembly and transportation. Alternatively, the magnetic separator support frame 80 can also be connected to the right side of the crusher support frame 10. Figure 2 The two support legs adopt a split assembly structure, and the magnetic separator support frame 80 is installed on top of the crusher support frame 10 by bolts.

[0031] This application also provides a coarse crushing device, including a crusher 300, a feeder 200, a magnetic separator 400, and a support structure as described above. The crusher 300 is detachably installed at the crusher mounting position of the crusher support frame 10, the feeder 200 is detachably installed at the feeder mounting position of the feeder support frame 20, the feed hopper 30 is installed above the feeder 200, and the magnetic separator 400 is suspended below the crossbeam of the magnetic separator support frame 80 and is vertically distributed with the conveyor belt (the conveyor belt passes under the magnetic separator 400 from the crusher discharge hopper 40 and extends to the next processing module). When the coarse crushing equipment is working, the sand and gravel in the raw material bin flow into the feed hopper 30. Large stones enter the crusher 300 for crushing under the vibration of the feeder 200, and then flow out from the crusher discharge hopper 40. Smaller stones enter the feeder discharge hopper 50 under the vibration of the feeder 200, and flow out from the two discharge ports of the feeder discharge hopper 50.

[0032] In summary, this application adopts a modular design for the main support structure, dividing it into multiple modules such as the crusher support frame 10, feeder support frame 20, feed hopper 30, crusher discharge hopper 40, feeder discharge hopper 50, maintenance platform 60, ladder assembly 70, and magnetic separator support frame 80. The larger modules are detachably connected. Each module is prefabricated in the factory, featuring standardized interfaces and dimensions, high versatility, and the ability to achieve mass production. This significantly improves the efficiency of manufacturing, transportation, and on-site assembly, facilitating packaging, transportation, and on-site assembly. During on-site assembly, the various modules of the coarse crushing equipment can be quickly assembled together using bolts, pins, and other connectors, eliminating the need for complex welding and debugging processes. This ensures a strong connection and easy disassembly, making it suitable for project relocation. Secondary transport can be achieved by disassembling it into smaller units, making assembly and disassembly very convenient and easy to operate. The overall cost is lower, solving the technical problems of existing integral welded coarse crushing steel structures, such as cumbersome on-site welding, difficult secondary transport, long construction periods, and difficult maintenance.
