Description

Technical Field

[0001] This utility model relates to the field of mining equipment technology, and in particular to an automated mining conveying equipment. Background Technology

[0002] As a key continuous transportation equipment in mining, the stability and reliability of belt conveyors directly affect the efficiency of the entire production process. During the transportation of bulk materials such as ore and coal, due to the moisture content, viscosity, and surface characteristics of the materials, some materials will inevitably adhere to the working surface of the conveyor belt.

[0003] When the conveyor belt finishes unloading and begins its return journey, if the remaining material is not effectively removed, it will be carried onto the return rollers, drums, and other components as the conveyor belt continues to run. The continuous accumulation of material on these components gradually forms an irregular layer, causing uneven diameters of the rollers or drums. This results in tension imbalance on both sides of the conveyor belt, which is one of the main causes of conveyor belt misalignment.

[0004] If a conveyor belt deviates from its designated path, its edges will rub violently against supports and other components. This can lead to rapid wear on the conveyor belt edges, or even serious equipment accidents such as belt tearing, resulting in significant economic losses and production interruptions. Simultaneously, residual material continuously falls during the return journey, wasting valuable resources and causing dust or mud pollution along the conveyor line, which does not meet the requirements of modern green mining production. Existing simple cleaning devices are often simplistic in structure and limited in function, offering poor cleaning results and difficulty in effectively recovering the swept material. They still require significant manual labor for auxiliary cleaning, have low automation levels, and fail to fundamentally solve the problem.

[0005] Therefore, this utility model proposes an automated mining conveying equipment to address the shortcomings of the existing technology. Utility Model Content

[0023] Example 1, referring to Figures 1 to 4 This utility model provides an automated mining conveying equipment, which aims to solve the problems of conveyor belt misalignment and wear caused by material residue in existing mining conveying equipment, and the complicated maintenance and replacement process of key components such as rollers.

[0024] like Figure 1 As shown, the automated mining conveying equipment includes a support frame 1 as the overall supporting foundation, and an intermediate frame 2 mounted on the support frame 1. The intermediate frame 2 is used to support the conveyor belt 3, which is used to transport materials. The conveying equipment also includes a roller 4 that provides driving force to the conveyor belt 3, and a support 5 for rotatably supporting the roller 4. The outer periphery of the conveyor belt 3 is wrapped around the intermediate frame 2 and the roller 4. To solve the aforementioned technical problems, the automated mining conveying equipment innovatively integrates a cleaning mechanism 6 located below the support frame 1 and a quick-release mechanism 7 for connecting the support 5 and the support frame 1. The cleaning mechanism 6 is used to automatically clean and recycle residual materials on the surface of the return section of the conveyor belt 3, and the quick-release mechanism 7 is used to realize the quick disassembly and maintenance of the roller 4. Specifically, refer to Figure 1 and Figure 2The cleaning mechanism 6 includes a cleaning component 63 for directly cleaning the surface of the conveyor belt 3, and a recovery component 66 located below the cleaning component 63 for recovering the cleaned material. The cleaning component 63 is fixed to the bracket 1 by a fixing seat 61. The cleaning component 63 also includes a support rod 62 that provides installation space for the internal device. The return section of the conveyor belt 3 passes through the cleaning component 63. The cleaning component 63 contains a cleaning cylinder 632 and a pressure roller 633. Both the cleaning cylinder 632 and the pressure roller 633 are rotatably connected to the support rod 62. The return section of the conveyor belt 3 is located between the cleaning cylinder 632 and the pressure roller 633. The pressure roller 633 presses the conveyor belt 3 and makes its surface adhere to the outer periphery of the cleaning cylinder 632. The cleaning component 63 also includes a motor 631. The output end of the motor 631 is connected to the cleaning cylinder 632 for driving the cleaning cylinder 632 to rotate, thereby cleaning the surface of the adhered conveyor belt 3. The recovery component 66... Located directly below the cleaning component 63, the recycling component 66 is used to collect materials falling from the cleaning cylinder 632. The recycling component 66 includes a support plate 64 and a base plate 65, with the base plate 65 fixedly connected to the bottom of the support plate 64. The recycling component 66 also includes a transmission recycling device for collecting materials. This device includes a second motor 661, a rotating shaft 662, a gear 663, a chain 664, and a scraper 665. Both the second motor 661 and the rotating shaft 662 are mounted on the support plate 64. The output end of the second motor 661 is connected to the rotating shaft 662 for transmission. The gear 663 is fixed on the rotating shaft 662, the chain 664 is wound around the gear 663, and the scraper 665 is fixedly connected to the outside of the chain 664 and close to the surface of the base plate 65. When the second motor 661 starts, the scraper 665 is driven by the gear 663 and the chain 664 to reciprocate on the surface of the base plate 65, thereby scraping the material received on the base plate 65 to the designated position for unified recycling.

[0025] Reference Figure 1 , Figure 3 and Figure 4The quick-release mechanism 7 includes a first fixing plate 71, a second fixing plate 78, and a central shaft 72 for detachably locking the two together. The first fixing plate 71 is fixedly connected to the outer wall of the support 5, and the second fixing plate 78 is fixedly connected to the bracket 1 at a position corresponding to the first fixing plate 71. In the installed state, the central shaft 72 passes through the first fixing plate 71 and the second fixing plate 78 in sequence. One end of the central shaft 72 is fixedly connected to a knob 73 for manual operation by a worker, and the other end is fixedly connected to a latch 77 for locking. In the assembled state, knob 73 is located outside of fixing plate 71, while buckle 77 passes through fixing plate 78 and is located inside it. To achieve locking and unlocking, fixing plate 78 has a through hole matching the shape of buckle 77. When the central shaft 72 rotates to the locked position, the long axis of the buckle 77's cross-section intersects the long axis of the through hole at a 90-degree angle. Buckle 77 is blocked by the inner wall of fixing plate 78 and is difficult to pull out, thus locking the support 5 and bracket 1. When the operator presses and rotates knob 73 to the preset unlock position... When locked, the latch 77 rotates synchronously with the central shaft 72, aligning the long axis of the latch 77 with the long axis of the through hole. At this point, the latch 77 can smoothly pass through the through hole, allowing the central shaft 72 to be pulled out of the second fixing plate 78, thus achieving rapid separation of the support 5 and the bracket 1. To provide operating force feedback and ensure locking reliability, the quick-release mechanism 7 also includes a spring 74. The spring 74 is sleeved on the central shaft 72, positioned between the knob 73 and the first fixing plate 71. Both ends of the spring 74 elastically abut against the knob. The inner side of button 73 and the outer side of fixing plate 71 provide preload for the locked state. To prevent the central shaft 72 from accidentally falling off after unlocking, the quick-release mechanism 7 is also provided with a limiting ring 75 and a limiting plate 76. The limiting ring 75 is fixed on the central shaft 72 and located between fixing plate 71 and fixing plate 78. The limiting plate 76 is fixed on the inner side of fixing plate 71. When the central shaft 72 is pulled outward, the limiting ring 75 will abut against the limiting plate 76, thereby limiting the pull-out stroke of the central shaft 72 and preventing it from completely falling off.

[0026] As a preferred implementation method, to achieve efficient and thorough cleaning, please refer to... Figure 1 and Figure 2 The cleaning component 63 is specifically constructed as follows: it includes a support rod 62, a motor 631, a cleaning cylinder 632, and a pressure roller 633. The cleaning cylinder 632 and the pressure roller 633 are rotatably connected to the support rod 62. During the return journey of the conveyor belt 3, the pressure roller 633 presses the belt tightly and completely adheres to the outer circumference of the cleaning cylinder 632. The output end of the motor 631 is connected to the cleaning cylinder 632 to drive the cleaning cylinder 632 to rotate at high speed to scrape and clean the surface of the conveyor belt 3.

[0027] As another preferred implementation method, in order to achieve automated collection of the cleaned materials, please refer to... Figure 1The specific structure of the recycling component 66 is as follows: it includes a support plate 64, a second motor 661, a rotating shaft 662, a gear 663, and a chain 664. The base plate 65 is fixedly connected to the bottom of the support plate 64. The second motor 661 drives the rotating shaft 662 and the gear 663 fixed thereon to rotate. The chain 664 is wound around the gear 663. The scraper 665 fixed on the chain 664 moves in a cycle, thereby pushing the material on the base plate 65 to the recycling port.

[0028] As a preferred overall equipment layout, in order to ensure the stability and symmetry of the roller 4 installation, there are two supports 5, which are rotatably supported at both ends of the roller 4. Each support 5 is detachably connected to the bracket 1 through an independent quick-release mechanism 7, realizing synchronous and quick assembly and disassembly on both sides.

[0029] As a further optimization of the quick-release mechanism 7, in order to provide a reset force and ensure the reliability of locking, the quick-release mechanism 7 also includes a spring 74 sleeved on the central shaft 72, with the two ends of the spring 74 elastically abutting against the inner side of the knob 73 and the outer side of the fixing plate 71, respectively.

[0030] To further enhance the safety of the quick-release mechanism 7, in order to prevent the central shaft 72 from accidentally coming out, the quick-release mechanism 7 also includes a limiting ring 75 fixed on the central shaft 72 and located between the first fixing plate 71 and the second fixing plate 78, and a limiting plate 76 fixed inside the first fixing plate 71. The cooperation between the limiting plate 76 and the limiting ring 75 limits the maximum pull-out distance of the central shaft 72.

[0031] As a further improvement to the ease of operation of the quick-release mechanism 7, please refer to Figure 3 and Figure 4 The knob 73 is provided with a radially extending handle, and the fixing plate 78 is provided with a limiting groove that cooperates with the handle. The limiting groove is used to precisely limit the rotation angle of the knob 73, ensuring that it can be easily switched between the locked and unlocked positions.

[0032] The working principle is as follows: During equipment operation, the conveyor belt 3 circulates under the drive of the roller 4 to transport materials. When the return section of the conveyor belt 3 passes the cleaning mechanism 6, the residual material on its surface is automatically removed and recycled. Specifically, the return section of the conveyor belt 3 first enters the cleaning component 63, where its surface is tightly pressed against the outer peripheral wall of the cleaning cylinder 632 under the action of the pressure roller 633. At this time, the motor 631 is started, driving the cleaning cylinder 632 to rotate, thereby scraping and cleaning the surface of the conveyor belt 3. The cleaned material falls off due to gravity. The material falls onto the base plate 65 of the recycling component 66 below. Then, the second motor 661 is started. The second motor 661 drives the rotating shaft 662, gear 663 and chain 664 to drive the scraper 665 fixed on the chain 664 to perform a cyclic scraping motion along the surface of the base plate 65, thereby collecting the fallen material into a designated location. Through this synergistic effect of the cleaning component 63 and the recycling component 66, this utility model effectively solves the problems of conveyor belt deviation, wear and tear, material waste and environmental pollution caused by material residue in the prior art.

[0033] When the worn roller 4 needs to be replaced or repaired, the operator can quickly disassemble or assemble it using the quick-release mechanism 7 without the need for complicated tools. Specifically, during disassembly, the operator first presses the knob 73, which compresses the spring 74 between the knob 73 and the fixing plate 71. While pressing, the operator rotates the knob 73 ninety degrees. The rotation of the knob 73 will synchronously drive the buckle 77 at the other end to rotate through the central shaft 72 until the outline of the buckle 77 is aligned with the direction of the through hole on the fixing plate 78 that matches the shape of the buckle 77. At this point... With the buckle 77 no longer obstructed by the inner wall of the fixing plate 78, the operator can pull the central shaft 72 out of the fixing plate 78 until the limiting ring 75 on the central shaft 72 is blocked by the limiting plate 76, thereby achieving quick separation of the support 5 and the bracket 1, and thus easily removing the roller 4; during installation, the opposite steps are performed. Through the synergistic effect of the quick-release mechanism 7's ingenious pressing, rotating and locking, the maintenance process of the roller 4 is greatly simplified, the downtime is significantly shortened, and the problem of time-consuming and laborious maintenance and replacement of the roller 4 in the existing technology is solved.
