Description

Technical Field

[0001] This invention relates to the field of buffer bed technology, specifically to a multi-segment elastic buffer device for mining belt conveyors. Background Technology

[0002] In belt conveyors, idlers are conventional components that support the conveyor belt and the materials it carries. Their initial design purpose is mainly to meet the load-bearing requirements of the horizontal material conveying stage, ensuring the smooth operation of the conveyor belt to complete the horizontal material transfer task. However, in actual working conditions, belt conveyor systems often have material transfer links where materials such as ores fall directly onto the conveyor belt from a height. The instantaneous impact force generated at this time far exceeds the load-bearing capacity limit of ordinary idlers. This not only easily causes the idlers to deform and be damaged, but also forms a strong impact on the conveyor belt itself, leading to problems such as conveyor belt tearing and accelerated wear, seriously affecting the operational stability and service life of the conveyor system. Therefore, buffer devices are used to replace idlers. Existing buffer devices are generally buffer beds, which are composed of multiple buffer strips. The buffer strips mainly use high-quality rubber layers to fully and effectively absorb the impact force when the material falls, greatly reducing the impact on the conveyor belt when the material falls, and truly improving the stress condition at the drop point.

[0003] However, existing technologies have the following problems: 1. During ore mining, the buffer bed is generally installed directly below the loading point at the tail end of the belt conveyor. This area needs to continuously withstand the continuous impact force generated by the ore falling from a height. Not only is the impact intensity extremely high, but the impact frequency is also high. Existing buffer beds generally absorb the main impact force through buffer bars or install springs under the buffer bed to further absorb the impact force. However, in actual use, it is difficult to maintain a long-term and stable buffering effect under high-intensity impact conditions, requiring frequent shutdowns for replacement, which seriously affects the continuity of production and the overall efficiency of the equipment.

[0004] 2. When used in coal mines or sulfur mines, the falling ore will generate high concentrations of coal dust or sulfur dust. Coal dust or sulfur dust is highly explosive. Since the buffer bed and the belt are in close contact, there is an inevitable gap between them. In actual use, high concentrations of coal dust or sulfur dust will continuously seep into this gap and accumulate. The accumulated dust will cause severe friction between the belt and the buffer bed when the belt is running at high speed, generating a large amount of heat. When the heat reaches the critical temperature for dust explosion, it is very easy to cause a dust explosion accident. At the same time, the dust will replace the lubricating medium on the contact surface, greatly increasing the friction coefficient between the belt and the buffer bed, causing the belt running resistance to soar. This will not only aggravate the wear on the belt surface, but also shorten the belt's service life. Summary of the Invention

[0005] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a multi-segment elastic buffer device for mining belt conveyors, which has the advantages of multi-segment synergistic buffering and dust blocking, and solves the problems of rapid attenuation of the buffering effect of existing buffer beds, easy accumulation of dust causing safety risks, severe equipment wear and frequent maintenance.

[0006] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: a multi-segment elastic buffer device for a mining belt conveyor, comprising multiple supports arranged in parallel, two support plates symmetrically arranged at the upper end of each support, multiple first buffer members arranged sequentially from top to bottom on the side of each support plate away from the support, a second buffer member arranged in the middle of each support, a set of base plates connected to the upper ends of every three supports, and the lower end of each set of base plates detachably connected to the first and second buffer members at the upper end of the support and support plates, a dust removal component detachably connected to one end of each set of base plates, and the dust removal direction of the dust removal component facing the longitudinal direction of the base plate to clean the surface of the base plate, and a first rubber layer snapped into the upper end of each set of base plates; The dust removal assembly includes a positioning box bolted to one end of a substrate.

The upper end of the support plate is provided with a rectangular array of second damping rods, and a helical spring is provided in the middle of the upper end of the support plate. The upper ends of the second damping rods and the helical spring are connected to a pressure plate. Positioning rods are symmetrically arranged on the left and right sides of the pressure plate. The other end of each positioning rod is slidably connected to the inner wall of one of the limiting rods. Multiple energy-absorbing blocks are uniformly arranged on the upper end of the pressure plate. The upper ends of the multiple energy-absorbing blocks are connected to a connecting plate. The upper end of the connecting plate is detachably connected to the lower end of the base plate.

[0011] Preferably, a positioning groove is provided on one side of the bracket, and a positioning block is fixedly connected to the other side of the bracket.

[0015] (III) Beneficial Effects Compared with the prior art, the present invention provides a multi-stage elastic buffer device for mining belt conveyors, which has the following beneficial effects: 1. This multi-stage elastic buffer device for mining belt conveyors, through the coordinated arrangement of the first and second buffer components, provides stronger buffering capacity when the belt conveyor carries large, high-density ore. It absorbs the continuous impact force generated by ore falling from a height, effectively reducing the instantaneous contact stress of the ore on the belt. This allows the belt conveyor to maintain a long-term, stable buffering effect under high-intensity impact conditions. Simultaneously, the bracket, support plate, first buffer component, and second buffer component form an independent support buffer, while the overall buffer bed is composed of several independent support buffer components. Therefore, during use, each independent support buffer component is lightweight and can be manually handled and installed without the need for large hoisting equipment. Furthermore, after prolonged use, damaged sections can be replaced during maintenance without disassembling the entire device. The multi-segment buffer bed significantly reduces downtime. It can also be customized with stronger first and second buffer components for material drop points with higher impact forces at the top of the buffer bed, while other areas use standard first and second buffer components. This targeted design, based on the different impact forces experienced at different locations on the top of the buffer bed, achieves on-demand buffering, avoiding overall over- or under-buffering. Compared to the single elastic buffer of an integrated buffer bed, the multi-segment design can more accurately match the impact characteristics of falling materials, improving the protection effect on the conveyor belt. Furthermore, even if the independent support buffer components suffer partial damage due to large ore impacts or material abrasion, the remaining independent support buffer components can still bear the load normally, preventing the entire buffer bed from failing. This greatly improves the fault tolerance and operational reliability of the buffer bed.

[0016] 2. This multi-stage elastic buffer device for mining belt conveyors, through the installation of a dust removal component, can perform dual cleaning of the substrate surface using both air jetting and atomization. This effectively removes high-concentration mining dust and other debris generated during operation, reducing dust accumulation in the gap between the belt and the buffer bed from the source, significantly lowering the risk of dust explosions, and effectively alleviating belt wear problems. During actual operation, the air pump inside the dust removal component continuously provides high-pressure gas, which is delivered to each jet nozzle through the air inlet pipe, forming a high-speed airflow that powerfully sweeps the substrate surface, quickly blowing away mining dust, loose debris, and some dust that has seeped into the gaps. This prevents dust from continuously accumulating at the contact surface between the belt and the buffer bed. Simultaneously, a high-pressure water source provided by a water pump is delivered to the atomizing nozzle through the water inlet pipe, forming a uniform atomized water film to clean the attached... The process wets and settles firmly attached dust particles, making them easier for the airflow to carry away. This achieves synergistic cleaning through jetting and atomization, significantly improving cleaning efficiency. The high-pressure gas and atomized water work together during spraying to moderately wet the upper surface of the substrate, forming a thin water film. This film not only effectively suppresses dust dispersion but also cools the belt during operation, reducing heat generated by friction between the belt and the substrate. This further reduces the possibility of dust reaching its explosive critical temperature, significantly improving equipment safety. Simultaneously, the wetted substrate surface effectively reduces the coefficient of friction between the belt and the buffer bed, decreasing running resistance and preventing increased friction caused by dust replacing the lubricating medium. This effectively alleviates belt wear and extends belt life. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1, please refer to Figures 1 to 13This invention provides a technical solution: a multi-segment elastic buffer device for a mining belt conveyor, comprising multiple parallel supports 1, each support 1 having two symmetrically arranged support plates 2 at its upper end, each support plate 2 having multiple first buffer elements 3 arranged sequentially from top to bottom on the side opposite to the support 1, each support 1 having a second buffer element 4 arranged in the middle, and each set of base plates 5 being connected to the upper ends of every three supports 1, with the lower end of each set of base plates 5 being detachably connected to the first buffer elements 3 and second buffer elements 4 at the upper ends of the support 1 and support plates 2. One end of each set of substrates 5 is detachably connected to a dust removal component 6, and the dust removal direction of the dust removal component 6 is towards the longitudinal direction of the substrate 5 to clean the surface of the substrate 5. The upper end of each set of substrates 5 is snapped with a first rubber layer 7. A positioning groove 8 is opened on one side of the bracket 1, and a positioning block 9 is fixedly connected to the other side of the bracket 1. The positioning block 9 is adapted to the positioning groove 8, and the positioning block 9 can be embedded in the positioning groove 8 of the adjacent bracket 1 to form a positioning fit, so as to realize the mutual positioning and connection of multiple brackets 1. Multiple threaded posts 10 are inserted sequentially along the transverse direction at the upper end of the bracket 1. The positioning groove 8 is located on one side of the support 1 and is used to cooperate with the positioning block 9 of the adjacent support 1 to achieve rapid positioning and connection of multiple supports 1. The positioning groove 8 ensures the alignment accuracy between the supports 1, making the installation of the entire buffer bed more accurate and efficient. At the same time, the positioning block 9 can be embedded in the positioning groove 8 of the adjacent support 1 to ensure the connection strength and stability between the supports 1. The positioning block 9 can also prevent the supports 1 from relative displacement under force, improving the overall structural integrity of the buffer bed. The threaded post 10 can fix the support 1 to the ground to ensure the firmness of the support 1 installation. At the same time, the threaded post 10 is detachable, which facilitates the maintenance and replacement of the support 1. The support 1, as the basic load-bearing component of the entire buffer bed, is used to bear the material. The support plate 1 receives the impact load and static load from the base plate 5 and all the buffer components. At the same time, the support plate 1 provides the mounting reference for the support plate 2, the second buffer component 4, the base plate 5, etc., so that the entire structure can be accurately assembled according to the design position. The support plate 2 can provide a stable mounting platform for the first buffer component 3. The function of the support plate 2 is to concentrate the dispersed load transmitted from the first buffer component 3 and then transmit it to the support plate 1, so as to avoid excessive local stress on the support plate 1 and also to limit the first buffer component 3. The base plate 5 set at the upper end of the support plate 1 first receives the impact force of the ore. The first rubber layer 7 at the upper end of the base plate 5 absorbs the impact force initially and then transmits the impact force evenly to the first buffer component 3 and the second buffer component 4. At the same time, it also provides the mounting base for the first rubber layer 7.

[0021] Please see Figure 1 , Figure 2 , Figure 7 and Figure 8The dust removal component 6 includes a positioning box 601 bolted to one end of the substrate 5. Multiple jet nozzles 602 are sequentially arranged laterally on the side of the positioning box 601 near the substrate 5, and an atomizing nozzle 603 is arranged between every two jet nozzles 602 on one side of the positioning box 601. The input ends of the jet nozzles 602 and atomizing nozzles 603 extend longitudinally into the interior of the positioning box 601. Each jet nozzle 602 has a detachable air inlet pipe 604 connected to its input end. A first main pipe 605 is located at the other end of the air inlet pipe 604, and an air pump 606 is located at the other end of the first main pipe 605. Each atomizing nozzle 603 has a detachable water inlet pipe 607 connected to its input end. A second main pipe 608 is located at the other end of the water inlet pipe 607, and a water pump 609 is located at the other end of the second main pipe 608. The jet nozzles 602 and atomizing nozzles 603... The outer surfaces are all in contact with the upper surface of the first rubber layer 7. The upper surface of the first rubber layer 7 has a first through hole corresponding to the output port position of the jet head 602 and the atomizing nozzle 603. A second rubber layer 610 is provided on the side of the jet head 602 and the atomizing nozzle 603 away from the first rubber layer 7. The second rubber layer 610 has a second through hole corresponding to the output port position of the jet head 602 and the atomizing nozzle 603. The first rubber layer 7 and the second rubber layer 610 together wrap the main body of the jet head 602 and the atomizing nozzle 603. The first through hole and the second through hole keep the output port of the jet head 602 and the atomizing nozzle 603 exposed to ensure that the jetting and atomizing functions are not affected. An arc-shaped baffle 611 is provided on the side of the positioning box 601 away from the jet head 602 and the atomizing nozzle 603. Two positioning plates 612 are symmetrically provided on the side of the positioning box 601 near the arc-shaped baffle 611. In the above technical solution, the positioning box 601 can fix the jet head 602, atomizing nozzle 603, air inlet pipe 604, and water inlet pipe 607, ensuring that each jet component maintains accurate jet angle and positional stability under high-speed belt operation and ore impact conditions. The first main pipe 605 can supply air to multiple air inlet pipes 604, collect the gas from multiple air inlet pipes 604, and connect them to the air pump 606, making the gas supply more stable and efficient. The centralized air supply structure can reduce pipeline pressure loss and ensure that each jet... Each nozzle 602 receives sufficient jet pressure to ensure effective purging. The second main pipe 608 connects multiple water inlets 607 to a unified water pump 609 for centralized water supply. This centralized supply effectively avoids pressure differences between the atomizing nozzles 603, resulting in more stable and uniform atomization. During actual water supply, the water pump 609 can be directly connected to an external water source to ensure continuous and reliable water supply. Furthermore, during installation, the outer surfaces of the jet nozzles 602 and atomizing nozzles 603 are protected. Both layers are attached to the upper surface of the first rubber layer 7, which protects the lower surfaces of the jet nozzle 602 and the atomizing nozzle 603. The second rubber layer 610, in conjunction with the first rubber layer 7, encloses the main body of the jet nozzle 602 and the atomizing nozzle 603, providing protection, dust prevention, and impact resistance. The second rubber layer 610 also improves the structural sealing, preventing dust from entering the positioning box 601. In practical applications, the first rubber layer 7 and the second rubber layer 610 can absorb the impact of ore from the upper end of the conveyor belt. The impact force is absorbed to prevent the impact force generated by the ore from directly contacting the jet head 602 and atomizing nozzle 603 through the belt on the surface of the buffer bed, thus avoiding damage. This improves the impact resistance and overall durability of the dust removal component 6. The first and second through holes inside the first rubber layer 7 and the second rubber layer 610 allow the output ports of the jet head 602 and atomizing nozzle 603 to remain exposed, ensuring that the spray channel is unobstructed and that high-pressure gas and atomized water can be sprayed out smoothly, thereby ensuring that the dust removal, cooling and dust suppression functions are not affected. Furthermore, it is worth noting that when the dust removal component 6 is installed at the connection point of the two substrates 5, the positioning plates 612 symmetrically arranged on both sides of the positioning box 601 can play a dual role of precise positioning and reserving a dust discharge channel. During the process of the worker installing the dust removal component 6 onto one end of the substrate 5, the positioning box 601 connects to one end of one substrate 5, while the side of the positioning plate 612 facing away from the positioning box 601 abuts against one end of the other substrate 5, creating a stable gap between the positioning box 601 and the end of the substrate 5, preventing them from sticking together and causing dust accumulation and blockage. When the dust removal component 6 is activated to perform jet and atomized cleaning on the upper part of the substrate 5, the dust blown down by the high-pressure airflow will be cleaned along the surface of the substrate 5. The dust is pushed to the other end of the substrate 5, and the gap reserved in the positioning plate 612 forms a dedicated dust discharge channel, so that the cleaned mineral dust can be discharged smoothly and will not accumulate at the connection between the positioning box 601 and the substrate 5. This ensures the installation stability of the dust removal component 6 and ensures that the cleaned mineral dust can be discharged in time, avoiding cleaning failure or equipment failure caused by secondary accumulation, and further improving the working reliability of the dust removal component 6. At the same time, when the mineral dust is pushed to the other end of the substrate 5, the arc-shaped baffle 611 set on the side of the positioning box 601 near the positioning plate 612 can guide the mineral dust into the reserved gap, preventing dust and water mist during cleaning from splashing outwards and onto the surface of another substrate 5.

[0022] Please see Figure 2 and Figure 3 Each first buffer 3 includes a force rod 301 inserted into the support plate 2. The upper end of the force rod 301 is provided with a first damping rod 302. The outer surface of the first damping rod 302 is sleeved with a reset spring 303, and the upper end of the first damping rod 302 is detachably connected to the lower end of the base plate 5. Among them, the multiple first buffers 3 on the upper end of the support plate 2 can effectively absorb the impact load generated by the ore falling on the left and right sides of the upper end of the support 1 base plate 5, providing uniform and reliable elastic support for the base plate 5. The first damping rod 302 inside the first buffer 3 can provide damping force and absorb impact energy. Especially when the belt is impacted by large pieces of material, it can effectively attenuate the impact and vibration, and avoid resonance. At the same time, the setting of the first damping rod 302 can enable the base plate 5 to quickly return to a stable state after being subjected to instantaneous strong impact, avoiding continuous oscillation, effectively improving the running stability of the belt on the upper end of the base plate 5 under impact conditions, and reducing the risk of fatigue damage and belt deviation caused by vibration. After the return spring 303 completes the impact absorption, it can push the first damping rod 302 to quickly return to its original position through its own elastic restoring force, so that the first buffer 3 always maintains a good working state and ensures that the buffer bed can still operate stably under continuous impact conditions. It is worth noting that Since the buffer bed is composed of multiple independent supports 1, in actual use, the supports 1 and the first damping rod 302 at the corresponding position at the lower end of the base plate 5 can be flexibly replaced according to the impact intensity difference at different drop points. For example, they can be replaced with the first damping rod 302 with a larger damping force to adapt to the impact characteristics of different areas. Through the replaceable structure, the buffer bed can be customized according to the on-site working conditions to further improve its adaptability and buffering effect, ensuring that the best energy absorption and vibration reduction performance can be achieved at different drop positions. The force rod 301 can serve as the force transmission component of the first buffer 3, directly bearing the pressure of the first buffer 3 and directly applying the pressure of the first buffer 3 to the support 1, ensuring that the force transmission path is clear and does not deviate. The unabsorbed force is transmitted to the ground through the support 1. At the same time, the force rod 301 also plays a guiding role, ensuring that the first buffer 3 moves in the vertical direction during compression and reset, avoiding skewing or jamming.

[0023] Please see Figure 2 , Figure 4 and Figure 5Each second buffer 4 includes two limiting rods 401 symmetrically arranged on the upper end of the support 1 and a support plate 402 bolted to the upper end of the support 1. The upper end of the support plate 402 is provided with a rectangular array of second damping rods 403. A helical spring 404 is provided in the middle of the upper end of the support plate 402. The upper ends of the second damping rods 403 and the helical spring 404 are connected to a pressure plate 405. Positioning rods 406 are symmetrically arranged on the left and right sides of the pressure plate 405. The other end of each positioning rod 406 is slidably connected to the inner wall of a limiting rod 401. Multiple energy-absorbing blocks 407 are evenly arranged on the upper end of the pressure plate 405. The upper ends of the multiple energy-absorbing blocks 407 are connected to a connecting plate 408. The upper end of the connecting plate 408 is detachably connected to the lower end of the base plate 5. The energy-absorbing blocks 407 are polyurethane elastic blocks or metal honeycomb blocks, and the multiple energy-absorbing blocks 407 are evenly distributed in a matrix between the pressure plate 405 and the connecting plate 408. In the above technical solution, the second buffer 4 can directly absorb the impact force borne by the middle base plate 5 at the upper end of the support 1. The internal support plate 402 of the second buffer 4 is installed at the upper end of the support 1 to provide a mounting base for the second damping rod 403, the coil spring 404 and the bearing plate 405. The support plate 402 evenly transmits the load of the second buffer 4 to the support 1, and then to the ground through the support 1. At the same time, the support plate 402 can also ensure the accurate installation position of the second damping rod 403 and the coil spring 404, ensuring the force transmission path. The second damping rod 403 and the coil spring 404 can absorb the impact energy generated by the displacement of the middle base plate 5. Moreover, due to its high stiffness, the coil spring 404 can quickly compress and absorb energy when impacted, and quickly reset after the impact disappears. The cooperation between the coil spring 404 and the second damping rod 403 gives the second buffer 4 both elastic and damping characteristics, improving the buffering effect. In addition, the damping force of the second damping rod 403 is usually greater than that of the first damping rod 302 to cope with the greater impact force on the middle of the base plate 5. Under heavy loads and more severe impact conditions, the positioning rods 406 on both sides of the pressure plate 405 cooperate with the limiting rods 401 to further restrict the movement direction of the pressure plate 405, ensuring that the pressure plate 405 can only move in the vertical direction. The limiting rods 401 can prevent the pressure plate 405 from tilting or shifting when under force, ensuring that the second damping rod 403 and the helical spring 404 can work normally and avoid damage caused by uneven force, thereby improving the stability and service life of the second buffer 4. The connecting plate 408 is used to enhance the connection strength between the second buffer 4 and the base plate 5, ensuring that the impact borne by the middle base plate 5 can be reliably and evenly transmitted to the second buffer 4. When the connecting plate 408 is impacted by the base plate 5, the multiple energy-absorbing blocks 407 set at its lower end can further absorb high-frequency vibration and impact energy. The energy-absorbing blocks 407 are made of polyurethane elastic blocks or metal honeycomb blocks. These materials have excellent energy absorption performance and structural stability, which can effectively attenuate high-frequency vibration and further improve the overall energy absorption capacity and operational stability of the buffer bed. Furthermore, the second damping rod 403 inside the second buffer 4 is the same as the first damping rod 302 inside the first buffer 3. According to the difference in impact intensity at different drop points, the support 1 and the second damping rod 403 at the corresponding position at the lower end of the substrate 5 can be flexibly replaced. For example, it can be replaced with a second damping rod 403 with greater damping force to adapt to the impact characteristics of different areas. This ensures that the buffer bed can also achieve the optimal energy absorption and vibration reduction effect in the central core bearing area, further improving the adaptability of the buffer bed to complex working conditions.

[0024] Please see Figure 1 , Figure 6 , Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13Each set of substrates 5 includes a positive substrate 501 detachably connected to the upper end of the support 1 and inclined substrates 502 located on the left and right sides of the support 1. Inclined baffles 503 for positioning are symmetrically arranged on both sides of the positive substrate 501. A reinforcing plate 504 is fixedly connected to one side of the inner wall of the inclined baffle 503, and the other side of the reinforcing plate 504 is fixedly connected to one side of the positive substrate 501. An intercepting plate 505 is fixedly connected to the side of each inclined substrate 502 closest to the positive substrate 501, and the inner wall of the intercepting plate 505... The inclined baffle 503 is slidably connected to the side of the corresponding positive substrate 501. The inner wall of the inclined baffle 503 is in contact with the outer surface of the inclined substrate 502 to realize the sliding guidance and positioning of the inclined substrate 502 relative to the positive substrate 501. The inner wall of the interceptor plate 505 is provided with a plurality of discharge holes 506 in the longitudinal direction. Each inclined substrate 502 is provided with a plurality of temperature sensors 507 in the longitudinal direction on the side near the interceptor plate 505. One end of each of the multiple temperature sensors 507 extends out of one side of the inclined substrate 502 in the transverse direction. The base plate 5, mounted on the upper end of the support 1 and the first buffer 3 and the second buffer 4, is the main load-bearing component of the buffer bed. The base plate 5 distributes the load of the buffer bed evenly to the first buffer 3 and the second buffer 4, and provides a mounting base for the first rubber layer 7. The inclined baffles 503 on both sides of the positive base plate 501 guide and position the inclined base plate 502, ensuring it slides along a set direction. The inclined baffles 503 also prevent the inclined base plate 502 from shifting under load, improving structural stability. Meanwhile, the reinforcing plate 504 enhances structural strength, preventing deformation of the inclined baffles 503 during long-term use. The reinforcing plate 504 also improves the connection stiffness between the positive base plate 501 and the inclined baffles 503, making the entire base plate 5 structure more stable. The intercepting plate 505 is installed on... The inclined substrate 502 is positioned on one side to facilitate its installation on the side of the positive substrate 501. After the positive substrate 501 or the inclined substrate 502 is subjected to impact, it can ensure that the shaking amplitude at the connection between the inclined substrate 502 and the positive substrate 501 is reduced, avoiding excessive shaking amplitude that could damage the belt on the surface of the buffer bed. At the same time, multiple discharge holes 506 can also discharge the mineral dust that enters the interceptor plate 505, preventing material accumulation from affecting the operation of the structure. The interceptor plate 505 can also limit the sliding of the inclined substrate 502, ensuring the positional accuracy of the inclined substrate 502. In addition, multiple temperature sensors 507 can monitor the temperature of the substrate 5, promptly detecting abnormal friction or overheating of the belt on the surface of the buffer bed, further improving the safety of the buffer bed and preventing belt damage or safety accidents caused by friction overheating.

[0025] In summary, this multi-segment elastic buffer device for mining belt conveyors, during use, involves placing multiple supports 1 in parallel. Positioning blocks 9 on one side of each support 1 are embedded into the positioning slots 8 of adjacent supports 1, enabling rapid positioning and connection of the supports 1 and ensuring alignment accuracy and structural integrity. Threaded posts 10 are sequentially inserted into pre-drilled holes at the upper end of each support 1 in the transverse direction, and the supports 1 are fixed to the ground foundation. Multiple first buffer components 3 are installed on the surfaces of the two support plates 2 at the upper end of each support 1, and second buffer components 4 are installed in the middle of each support 1. A positive base plate 501 is installed on the upper end of the three supports 1 and connected to the second buffer components. 4. Connect the components, then slide the inclined substrate 502 onto both sides of the upright substrate 501 via the inclined baffle 503 and the interceptor plate 505. Next, connect the back of the inclined substrate 502 to the first buffer 3. Then, snap the first rubber layer 7 onto the upper end of the substrate 5, covering the entire surface of the substrate 5. Install the dust removal component 6 onto one end of the substrate 5 with bolts, creating a pre-reserved gap between the positioning box 601 and the end of the substrate 5 via the positioning plate 612. Simultaneously, attach the jet nozzle 602 and the atomizing nozzle 603 to the first rubber layer 7 and the second rubber layer 610, ensuring the spray nozzles are exposed. Connect the air inlet pipe 604 to the jet nozzle 602, and... After being collected into the first main pipe 605, it connects to the air pump 606. The water inlet pipe 607 is connected to the atomizing nozzle 603, and after being collected into the second main pipe 608, it connects to the water pump 609. When the ore falls from a height onto the conveyor belt, the impact force is first transmitted by the belt to the first rubber layer 7, where it undergoes initial buffering. The impact force after being buffered by the first rubber layer 7 is then transmitted to the base plate 5. The upright base plate 501 transmits the impact force to the second buffer 4 for absorption, while the inclined base plate 502 transmits it to the first buffer 3 for absorption. When the belt is running, the air pump 606 is started, and high-pressure gas flows through the first main pipe 605 and the air inlet pipe 608. 4. The air is delivered to each jet nozzle 602, forming a high-speed airflow that powerfully sweeps the surface of the substrate 5, blowing away floating dust and loose debris. Then, the water pump 609 is started, and high-pressure water is delivered to the atomizing nozzle 603 through the second main pipe 608 and the water inlet pipe 607, forming a uniform atomized water film. This film wets and settles the firmly attached dust. The high-speed airflow and atomized water work together to quickly blow the wetted dust off the surface of the substrate 5, improving cleaning efficiency. The swept dust moves along the surface of the substrate 5 to the end and is discharged through the gap reserved in the positioning plate 612. The arc-shaped baffle 611 guides the dust to prevent it from splashing onto other substrate 5 surfaces.
