Description

Technical Field

[0001] This invention relates to the field of material conveying equipment technology, specifically a slag belt conveyor. Background Technology

[0002] In industrial sectors such as mining and metallurgy, slag is a common industrial solid waste. Its efficient transportation and subsequent treatment are crucial for ensuring the continuity of production processes. Belt conveyors, due to their advantages of large conveying capacity, long conveying distance, and stable operation, have become core equipment in slag transportation operations. Existing slag belt conveyors typically consist of a drive unit, a load-bearing conveyor belt, idler rollers, a frame, and a feeding mechanism. Their working principle involves the drive unit driving the conveyor belt in a cyclical motion, utilizing the friction between the conveyor belt and the slag to achieve continuous slag transportation.

[0003] To adapt to the needs of slag conveying, some existing equipment has installed ordinary idler roller groups under the conveyor belt to improve the load-bearing stability of the conveyor belt, and a simple hopper structure at the discharge end to guide the slag collection. To further improve the applicability of the conveying process, some targeted improvement solutions have emerged in existing technologies. For example, some belt conveyors use V-shaped idlers instead of traditional parallel idlers, using the V-shaped structure to provide initial guidance for the slag and attempt to reduce material deviation during conveying. Other equipment has added a fixed screen plate structure at the feed end to achieve preliminary screening of the slag before it enters the conveyor belt, removing some oversized impurities. However, in actual slag conveying operations, the uneven particle size, hard texture, and fluctuating moisture content of the slag material present challenges. Existing belt conveyors still face numerous technical challenges: Firstly, existing equipment using V-shaped idlers often has a fixed V-angle, making it impossible to adaptively adjust to changes in pressure or belt misalignment during slag transport. When slag feed is uneven or belt tension is unbalanced, slag tends to shift to either side of the belt, leading to spillage and accumulation on the sides of the frame. This not only wastes materials but also requires additional manpower for cleaning, severely impacting the production environment and conveying efficiency. Secondly, existing belt conveyors equipped with screening structures often have fixed screens or only perform a single screening function, lacking coordinated design with the feeding mechanism. When screened slag is discharged from the hopper, the complex particle size distribution of the slag can easily cause blockage at the discharge port.

[0004] Therefore, those skilled in the art have proposed a slag belt conveyor to solve the above problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a slag belt conveyor, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a slag belt conveyor, comprising:

[0007] The frame serves as the supporting structure for the entire device;

[0008] A feed hopper, installed on one side of the frame, is used for introducing slag;

[0009] A mounting bracket is installed on the side of the frame away from the feed hopper;

[0010] A conveying assembly, mounted on the frame, is used to achieve continuous conveying of slag;

[0011] An automatic correction component is disposed inside the conveying component to keep the slag in the center of the conveying component.

[0012] A grading and buffering assembly is installed on the inner side of the fixed frame and is used for buffering and grading the slag.

[0013] A lubrication supply component, integrated on the automatic correction component, is used to provide lubrication to the moving parts of the automatic correction component;

[0014] An anti-clogging component, installed on the fixed frame and linked with the grading buffer component, is used to prevent slag discharge from clogging.

[0015] Preferably, the automatic correction assembly includes multiple mounting seats installed inside the frame. A correction roller is hinged to the inner side of each mounting seat. A U-shaped seat is fixedly installed inside the middle of each mounting seat. Two movable seats are slidably connected to the inner side of the U-shaped seat. A bearing roller is rotatably installed between the two movable seats. A bearing roller is fixedly connected to the end of each movable seat away from the bearing roller. A movable groove is formed on the outer surface of the bearing roller. A hinge rod is slidably connected inside the movable groove. The end of the hinge rod away from the movable seat is fixedly connected to the end of the correction roller. When the bearing roller moves downward under the pressure of slag, it can drive the movable seat and the connecting plate to move downward synchronously, causing the hinge rod to slide along the inner wall of the movable groove, thereby driving the correction roller to deflect and reducing the angle formed between the correction roller and the bearing roller.

[0016] Preferably, the lubrication supply assembly includes a temporary storage box, two mounting cylinders, a drive rod, a rubber piston, a first connecting pipe, and a second connecting pipe. The temporary storage box is detachably connected to the inner side of the U-shaped seat and is used to store lubricating oil. The two mounting cylinders are symmetrically fixed to the inner side of the U-shaped seat, and each has a cavity inside for accommodating the rubber piston. The rubber piston is slidably connected to the cavity of the mounting cylinder. One end of the drive rod is fixedly connected to the rubber piston, and the other end is fixedly connected to the movable seat. One end of the first connecting pipe communicates with the inside of the temporary storage box, and the other end communicates with the cavity of the mounting cylinder. One end of the second connecting pipe communicates with the cavity of the mounting cylinder, and the other end extends above the alignment roller and the support roller. When the movable seat moves down, it can drive the rubber piston to slide along the inner wall of the mounting cylinder, changing the air pressure in the cavity, so that the lubricating oil in the temporary storage box is sprayed onto the outer surface of the alignment roller and the support roller through the second connecting pipe.

[0017] Preferably, multiple nozzles are installed at intervals along the length of the outer surface of the second connecting pipe to achieve uniform spraying of lubricating oil, and the end of the first connecting pipe away from the mounting cylinder is connected to the interior of the temporary storage box.

[0018] Preferably, both the first connecting pipe and the second connecting pipe are equipped with one-way valves, and the two one-way valves have opposite conduction directions. The bottom end of the connecting plate is fixedly connected to two spring telescopic rods, and the bottom end of the spring telescopic rods is fixedly connected to the inner side of the U-shaped seat for elastic reset of the bearing roller.

[0019] Preferably, the conveying assembly includes a driven roller, a drive roller, a conveyor belt, and a second drive motor; the driven roller and the drive roller are both movably connected to the inner side of the frame via bearings and are spaced apart along the length of the frame; the conveyor belt is sleeved on the outside of the driven roller and the drive roller to form a closed-loop conveying surface; the second drive motor is installed on the top side of the frame, and a second synchronous pulley is fixedly connected to its drive end; a first synchronous pulley is fixedly connected to one end of the drive roller; the first synchronous pulley and the second synchronous pulley are connected by a belt drive, and when the second drive motor is working, it can drive the drive roller to rotate through the transmission of the second synchronous pulley, the belt, and the first synchronous pulley, thereby driving the conveyor belt to run.

[0020] Preferably, the grading buffer assembly includes two elastic buffer arms, a limiting seat, a comb-tooth screen plate, a drive disk, a movable rod, and a connecting rod; the two elastic buffer arms are symmetrically fixed inside the fixed frame; the limiting seat is fixedly connected to the top of the elastic buffer arms, and its inner side is provided with a sliding groove adapted to the comb-tooth screen plate; the comb-tooth screen plate is slidably installed in the sliding groove of the limiting seat for grading and screening slag; a synchronous wheel is fixedly connected to the outer side of the drive disk and one end of the drive roller, and the two synchronous wheels are connected by belt drive; one end of the connecting rod is eccentrically rotatably connected to the outer side of the drive disk, and the other end is hinged to one end of the movable rod; the other end of the movable rod is fixedly connected to the comb-tooth screen plate; when the drive disk rotates, the comb-tooth screen plate is driven to slide back and forth along the limiting seat through the crank-connecting rod mechanism formed by the connecting rod and the movable rod; the elastic buffer arms are used to sense the force change of the comb-tooth screen plate and transmit a linkage signal to the anti-clogging assembly.

[0021] Preferably, the anti-clogging component includes a fixed cylinder fixedly connected to the inner side of the fixed frame, a drive motor fixedly connected to the outer side of the fixed cylinder, a connecting shaft fixedly connected to the output end of the drive motor, and multiple rotating plates fixedly connected to the outer side of the connecting shaft. Two connecting grooves are formed on the outer surface of the fixed cylinder. The speed of the output end of the drive motor is controlled by a signal transmitted through an elastic buffer arm. The drive motor drives the connecting shaft to rotate, which in turn drives the rotating plates to rotate, thus orderly feeding the slag that enters the fixed cylinder from the connecting grooves.

[0022] Preferably, the system further includes a liquid supply assembly, which includes an inner liquid tank fixedly connected to the frame. A pump body is installed on the top of the liquid tank. An installation pipe is fixedly connected to the output end of the pump body, and an installation pipe is fixedly connected to the input end of the pump body. The end of the installation pipe away from the pump body is connected to the interior of the liquid tank. The outer surface of the installation pipe is connected to the interior of a temporary storage tank through multiple diversion pipes. A control valve is installed on the outside of the diversion pipes. A flow sensor is installed inside the temporary storage tank. When the lubricating oil level in the temporary storage tank is lower than a preset threshold, the flow sensor triggers the pump body to start, and the lubricating oil in the liquid tank is transported to the temporary storage tank through the installation pipe.

[0023] Preferably, the grading buffer assembly further includes two guide plates, which are symmetrically fixed to the inner side of the fixing frame and located below the comb screen plate, for guiding the graded slag to fall accurately onto the conveying assembly.

[0024] This invention provides a slag belt conveyor. It has the following beneficial effects:

[0025] 1. This invention constructs a mechanical linkage structure between the carrying roller and the straightening roller. When the carrying roller moves downward under the pressure of slag, the hinge rod can slide along the movable groove through the movable seat and connecting plate, thereby driving the straightening roller to deflect to reduce the V-shaped angle formed between it and the carrying roller. With the guiding effect of the V-shaped structure, automatic centering is achieved during the slag conveying process, effectively avoiding the problems of spillage or accumulation caused by slag deviation.

[0026] 2. This invention utilizes a mechanical linkage design between the movable seat and the lubrication structure. The movable seat drives a rubber piston to slide along the inner wall of the mounting cylinder. Pressure changes within the mounting cylinder cavity drive the lubricating oil in the storage tank to be precisely sprayed through connecting pipe two onto the outer surfaces of the correction roller and the bearing roller, achieving adaptive lubrication supply to the linkage components. Simultaneously, relying on the flow sensor within the storage tank and the coordinated operation of the storage tank and pump, an automatic grease replenishment action is triggered when the lubricating oil level in the storage tank is insufficient. The lubricating oil in the storage tank is promptly replenished through mounting pipe one, ensuring a continuous and sufficient supply of lubricating medium. This effectively reduces wear caused by friction in the linkage components, lowers the equipment failure rate and reduces the intensity of manual maintenance, thereby improving the operational stability and service life of the equipment under slag conveying conditions.

[0027] 3. This invention drives the comb-tooth screen plate to slide back and forth along the limiting seat through a crank-connecting rod mechanism. In conjunction with the elastic buffer support arm, it senses the force change of the comb-tooth screen plate and transmits a linkage signal to the anti-clogging component. This enables the coordinated operation of slag grading and screening and material discharge anti-clogging, effectively avoiding slag accumulation that affects conveying efficiency.

Detailed Implementation

[0038] The technical solutions in 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.

[0039] Please refer to Appendix 1 - Appendix Figure 9 This invention provides a slag belt conveyor, comprising:

[0040] Frame 1 serves as the supporting carrier for the entire device;

[0041] Feed hopper 2, installed on one side of frame 1, is used for introducing slag;

[0042] The fixing frame 3 is installed on the side of the frame 1 away from the feed hopper 2;

[0043] A conveying assembly, mounted on frame 1, is used to achieve continuous conveying of slag;

[0044] The conveying assembly includes a driven roller 302, a drive roller 303, a conveyor belt 301, and a second drive motor 14. The driven roller 302 and the drive roller 303 are movably connected to the inner side of the frame 1 through bearings and are arranged at intervals along the length of the frame 1. The conveyor belt 301 is sleeved on the outer side of the driven roller 302 and the drive roller 303 to form a closed-loop conveying surface. The second drive motor 14 is installed on the top side of the frame 1, and its drive end is fixedly connected to a second synchronous pulley 13. One end of the drive roller 303 is fixedly connected to a first synchronous pulley 12. The first synchronous pulley 12 and the second synchronous pulley 13 are connected by belt drive. When the second drive motor 14 is working, it can drive the drive roller 303 to rotate through the transmission of the second synchronous pulley 13, the belt, and the first synchronous pulley 12, thereby driving the conveyor belt 301 to run.

[0045] Specifically, the core operating principle of the conveying assembly is to achieve stable closed-loop motion of the conveyor belt 301 through power transmission and roller shaft cooperation, thereby completing the continuous conveying of slag: After the drive motor 14 starts, it outputs rotational power, and the synchronous pulley 13 at its drive end drives the synchronous pulley 12 at one end of the drive roller 303 to rotate synchronously through the friction of the belt, transmitting power to the drive roller 303; when the drive roller 303 rotates under the support of the bearing, it drives the conveyor belt 301 to move by means of the friction between it and the conveyor belt 301, while the driven roller 302 rotates synchronously under the traction of the conveyor belt 301, playing the role of supporting the conveyor belt 301 and maintaining the closed-loop conveying surface shape, so that the conveyor belt 301 forms a uniform speed circulating conveying trajectory, providing a stable bearing and transfer carrier for the slag.

[0046] An automatic alignment component, located inside the conveying assembly, is used to keep the slag in the center position of the conveying assembly. The automatic alignment component includes multiple mounting seats 401 mounted inside the frame 1. Alignment rollers 403 are hinged to the inner side of each mounting seat 401. A U-shaped seat 402 is fixedly mounted inside the center of each mounting seat 401. Two movable seats 405 are slidably connected to the inner side of the U-shaped seat 402. A bearing roller 404 is rotatably mounted between the two movable seats 405. A fixed connection is made to the end of each movable seat 405 away from the bearing roller 404. The bearing roller 404 has a movable groove 407 on its outer surface. A hinge rod 408 is slidably connected inside the movable groove 407. The end of the hinge rod 408 away from the movable seat 405 is fixedly connected to one end of the correction roller 403. When the bearing roller 404 moves downward under the pressure of slag, it can drive the movable seat 405 and the connecting plate 406 to move downward synchronously, so that the hinge rod 408 slides along the inner wall of the movable groove 407, thereby driving the correction roller 403 to deflect and reducing the angle formed between the correction roller 403 and the bearing roller 404.

[0047] Specifically, mechanical linkage is triggered by slag pressure, and automatic slag centering is achieved by dynamically adjusting the roller angle: When the slag is conveyed on the conveyor belt 301, its weight will exert pressure on the bearing roller 404 below. When the slag is unevenly distributed or too heavy, the bearing roller 404 will move downward under pressure; this movement drives the movable seat 405 and the connecting plate 406 to move downward synchronously, thereby pulling the hinge rod 408 to slide along the inner wall of the movable groove 407 of the bearing roller 404. The transmission force of the hinge rod 408 drives the correction. Roller 403 deflects around the hinge point of mounting base 401, reducing the V-shaped angle formed by the correction roller 403 and the carrying roller 404. With the lateral guiding constraint force generated by the reduced V-shaped structure, the offset slag is gradually pushed back to the center position of the conveyor belt 301. At the same time, the spring telescopic rod 11 at the bottom of the connecting plate 406 will move down with the carrying roller 404 to compress and store energy. When the slag pressure decreases, the elastic potential energy is released, driving the components to reset, ensuring continuous adaptation to the pressure changes during the slag conveying process and maintaining the slag centering state stably.

[0048] The grading and buffering assembly is installed on the inside of the fixing frame 3 and is used for buffering and grading the slag.

[0049] The grading buffer assembly includes two elastic buffer arms 603, a limiting seat 604, a comb-tooth screen plate 601, a drive disc 605, a movable rod 606, and a connecting rod 607. The two elastic buffer arms 603 are symmetrically fixed inside the fixing frame 3. The limiting seat 604 is fixedly connected to the top of the elastic buffer arms 603, and its inner side has a sliding groove adapted to the comb-tooth screen plate 601. The comb-tooth screen plate 601 is slidably installed in the sliding groove of the limiting seat 604 for grading and screening slag. The outer side of the drive disc 605 is fixedly connected to one end of the drive roller 303. Synchronous pulley 12, two synchronous pulleys 12 are connected by belt drive; one end of connecting rod 607 is eccentrically rotatably connected to the outside of drive disc 605, and the other end is hinged to one end of movable rod 606; the other end of movable rod 606 is fixedly connected to comb-tooth screen plate 601; when drive disc 605 rotates, the comb-tooth screen plate 601 is driven to reciprocate along limit seat 604 through crank-connecting rod mechanism formed by connecting rod 607 and movable rod 606; elastic buffer support arm 603 is used to sense the force change of comb-tooth screen plate 601 and transmit linkage signal to anti-blocking component.

[0050] Specifically, slag grading is achieved by driving the screen plate to reciprocate through power transmission, and linkage with the anti-clogging component is realized through force sensing: when the drive roller 303 rotates, the drive disc 605 rotates synchronously through the transmission of the synchronous pulley 12 and the belt. The drive disc 605 serves as the power input end of the crank-connecting rod mechanism, and its eccentrically connected connecting rod 607 swings in a circular motion at one end, which in turn pulls the movable rod 606 to perform linear reciprocating motion through the hinge point, ultimately driving the comb-tooth screen plate 601 to slide back and forth along the sliding groove of the limiting seat 604. The comb structure of the comb-tooth screen plate 601 can grade the slag, separating slag of different particle sizes and avoiding clogging of subsequent feeding. It achieves graded feeding, and the reciprocating sliding motion can prevent slag from accumulating on the screen plate surface, improving screening efficiency. The elastic buffer arm 603 serves as a force sensing component, with its top supporting the limiting seat 604 and the comb-tooth screen plate 601. When the amount of slag feed increases or large pieces of slag are retained, causing an increase in the force on the comb-tooth screen plate 601, the elastic buffer arm 603 will deform accordingly. Through mechanical signal feedback, it transmits a linkage command to the anti-clogging component, providing a basis for subsequent adjustment of the feeding speed and prevention of clogging. When the amount of slag decreases and the force on the screen plate decreases, the elastic buffer arm 603 returns to its initial state, ensuring that the screening process is stably adapted to the slag conveying conditions.

[0051] A lubrication supply component, integrated into the automatic alignment component, is used to provide lubrication to the moving parts of the automatic alignment component. The lubrication supply component includes a storage box 16, two mounting cylinders 801, a drive rod 802, a rubber piston 803, a first connecting pipe 804, and a second connecting pipe 805. The storage box 16 is detachably connected to the inside of the U-shaped seat 402 and is used to store lubricating oil. The two mounting cylinders 801 are symmetrically fixed to the inside of the U-shaped seat 402, and each has a cavity inside to accommodate the rubber piston 803. The rubber piston 803 is slidably connected within the cavity of the mounting cylinder 801. The drive rod 802... One end of the connecting pipe 804 is fixedly connected to the rubber piston 803, and the other end is fixedly connected to the movable seat 405. One end of the connecting pipe 804 is connected to the inside of the temporary storage box 16, and the other end is connected to the cavity of the mounting cylinder 801. One end of the connecting pipe 805 is connected to the cavity of the mounting cylinder 801, and the other end extends above the straightening roller 403 and the bearing roller 404. When the movable seat 405 moves down, it can drive the rubber piston 803 to slide along the inner wall of the mounting cylinder 801, changing the air pressure in the cavity, so that the lubricating oil in the temporary storage box 16 is sprayed onto the outer surface of the straightening roller 403 and the bearing roller 404 through the connecting pipe 805. Multiple nozzles are installed at intervals along the length of the outer surface of the connecting pipe 805 to achieve uniform spraying of lubricating oil. The end of the connecting pipe 804 away from the mounting cylinder 801 is connected to the inside of the temporary storage box 16.

[0052] Specifically, adaptive lubrication supply is achieved through the mechanical movement of the automatic correction assembly, ensuring that the linkage parts are continuously lubricated. The power source is the downward movement of the movable seat 405 within the automatic correction assembly. When the movable seat 405 moves, it drives the drive rod 802 to move synchronously, which in turn pulls the rubber piston 803 to slide along the inner wall of the cavity of the mounting cylinder 801. The rubber piston 803, as a key power conversion component, creates a pressure difference driving force by changing the air pressure within the cavity of the mounting cylinder 801. Under this driving force, the lubricating oil stored in the temporary storage box 16 enters the cavity of the mounting cylinder 801 through connecting pipe one 804, and is then transported to the moving parts of the automatic correction assembly through connecting pipe two 805. Multiple nozzles spaced apart on the outer surface of connecting pipe two 805 are the core component for uniform lubrication, dispersing the lubricating oil into a fine mist that is evenly sprayed onto the outer surfaces of the correction roller 403 and the support roller 404, preventing insufficient or excessive lubrication in certain areas. The entire process requires no additional power source, achieving synchronous linkage between the correction action and lubrication replenishment. This ensures that the greater the slag pressure and the more frequent the movement of the components, the more timely the lubrication supply, effectively reducing mechanical wear and ensuring the smooth operation of the automatic correction components.

[0053] Both connecting pipe 1 (804) and connecting pipe 2 (805) are equipped with one-way valves. The two one-way valves have opposite conduction directions. The bottom end of the connecting plate 406 is fixedly connected to two spring telescopic rods 11. The bottom end of the spring telescopic rods 11 is fixedly connected to the inner side of the U-shaped seat 402 for elastic reset of the bearing roller 404.

[0054] The anti-clogging component is installed on the fixed frame 3 and is linked with the grading buffer component to prevent slag discharge blockage.

[0055] The anti-clogging component includes a fixed cylinder 701 fixedly connected to the inner side of the fixed frame 3, a drive motor 702 fixedly connected to the outer side of the fixed cylinder 701, a connecting shaft 704 fixedly connected to the output end of the drive motor 702, and multiple rotating plates 703 fixedly connected to the outer side of the connecting shaft 704. Two connecting grooves 705 are opened on the outer surface of the fixed cylinder 701. The speed of the output end of the drive motor 702 is controlled by the transmission of signals through the elastic buffer support arm 603. The drive motor 702 will drive the connecting shaft 704 to rotate, which in turn drives the rotating plates 703 to rotate, so as to orderly feed the slag that enters the fixed cylinder 701 from the connecting grooves 705.

[0056] Specifically, the elastic buffer arm 603, as a key linkage signal transmission component, senses the force changes of the comb-shaped screen plate 601 in real time. When the slag feed rate increases or large slag pieces are retained, causing increased force on the screen plate, the elastic buffer arm 603 converts the mechanical signal into a control command and transmits it to the drive motor 702, adjusting its output speed. After the drive motor 702 starts, it drives the connecting shaft 704 to rotate, which in turn drives multiple rotating plates 703 on the outside of the connecting shaft 704 to rotate synchronously. The rotating plates 703 are the core execution components for anti-clogging and material feeding. During their rotation, they can generate a stirring and pushing force on the slag entering the fixed cylinder 701, breaking the adhesion and accumulation between slag particles. After the slag enters the cylinder through the connecting groove 705 on the outer surface of the fixed cylinder 701, under the continuous action of the rotating plates 703, it falls evenly and orderly from the bottom connecting groove 705 onto the conveying assembly, effectively avoiding clogging problems caused by complex slag particle size distribution and uneven feeding rate.

[0057] It also includes a liquid supply assembly, which includes a liquid storage tank 15 fixedly connected to the frame 1. A pump body 5 is installed on the top of the liquid storage tank 15. An installation pipe 9 is fixedly connected to the output end of the pump body 5, and an installation pipe 10 is fixedly connected to the input end of the pump body 5. The end of the installation pipe 10 away from the pump body 5 is connected to the inside of the liquid storage tank 15. The outer surface of the installation pipe 9 is connected to the inside of the temporary storage tank 16 through multiple diversion pipes. A control valve is installed on the outside of the diversion pipes. A flow sensor is installed inside the temporary storage tank 16. When the lubricating oil level in the temporary storage tank 16 is lower than a preset threshold, the flow sensor triggers the pump body 5 to start, and the lubricating oil in the liquid storage tank 15 is transported to the temporary storage tank 16 through the installation pipe 9.

[0058] Specifically, the flow sensor inside the temporary storage tank 16 is the core monitoring component. It continuously senses the remaining amount of lubricating oil in the tank. When the remaining amount is lower than a preset threshold, the flow sensor triggers a control signal to start the pump body 5. After the pump body 5 starts, it generates suction power and draws lubricating oil from the liquid storage tank 15 through the second installation pipe 10. The lubricating oil is then transported to the temporary storage tank 16 through the first installation pipe 9 and multiple external diversion pipes. The control valves outside the diversion pipes can precisely adjust the grease replenishment flow rate to prevent excessive lubricating oil overflow and ensure that the temporary storage tank 16 always maintains a sufficient amount of lubricating oil.

[0059] The grading buffer assembly also includes two guide plates 602, which are symmetrically fixed to the inside of the fixing frame 3 and located below the comb screen plate 601, for guiding the graded slag to fall accurately onto the conveying assembly.

[0060] Specifically, a guiding structure ensures precise collection and stable discharge of slag, guaranteeing stable operation of the conveying components. The symmetrically fixed arrangement of the guide plates 602 forms a converging guiding channel. After being screened by the comb-tooth screen plate 601, the graded slag, regardless of particle size, falls onto the surface of the guide plates 602 under gravity. The tilt angle and surface morphology of the guide plates 602 are adaptively designed to guide the slag along a preset trajectory, preventing it from spreading or splashing to either side during its descent, while also slowing its falling speed and reducing the impact on the conveying equipment below. Through this directional guiding effect, the slag falls precisely to the center of the conveyor belt 301, complementing the centering effect of the automatic correction components and preventing spillage or localized wear of the conveyor belt 301 caused by slag deviation, ensuring the continuity and stability of slag conveying.

[0061] Working principle: When the drive motor 14 is started, its drive end drives the synchronous pulley 13 to rotate. The synchronous pulley 13, through belt transmission, drives the synchronous pulley 12 at one end of the drive roller 303 to rotate synchronously, thereby driving the drive roller 303 to rotate. With the cooperation of the drive roller 303 and the driven roller 302, the conveyor belt 301, which is sleeved on the outside of both, forms a closed-loop circulation motion, providing the basic operating carrier for slag conveying. Simultaneously, when the drive roller 303 rotates, through the transmission of another set of synchronous pulleys 12 and the belt, it drives the drive disc 605 in the grading buffer assembly to rotate synchronously, providing power for subsequent slag screening.

[0062] After being fed into the feed hopper 2, the slag first falls onto the comb-tooth screen plate 601 inside the fixed frame 3. When the drive disc 605 rotates, the connecting rod 607 eccentrically connected to its outer side swings at one end, and drives the movable rod 606 to move back and forth through the traction force. This drives the comb-tooth screen plate 601 to slide back and forth along the sliding groove of the limiting seat 604. The comb structure is used to classify and screen the slag. Slag with a particle size smaller than the gap between the comb teeth passes through the screen plate, while slag with a larger particle size moves along the edge of the screen plate, thus achieving the initial classification of the slag. After grading, the slag falls onto the guide plate 602 below and is guided by the guide plate 602 to accurately enter the connecting groove 705 at the top of the fixed cylinder 701, and finally enters the interior of the fixed cylinder 701. During this process, the elastic buffer support arm 603 on the inner side of the fixed frame 3 senses the force change of the comb screen plate 601 in real time. When the slag accumulates, the force increases and transmits a linkage signal to the drive motor 702 of the anti-clogging component. By adjusting the output speed of the drive motor 702, the connecting shaft 704 and the outer rotating plate 703 are driven to rotate synchronously, which stirs and pushes the slag in the fixed cylinder 701, ensuring that the slag falls orderly onto the conveyor belt 301 through the bottom connecting groove 705, and avoiding blockage of the discharge port.

[0063] When the conveyor belt 301 is running, the bearing roller 404 below it carries the conveyor belt 301 and the slag. The bearing roller 404 and the correction rollers 403 on both sides initially form a V-shaped structure to provide initial guidance for the slag. When the weight of slag on the conveyor belt 301 is uneven or the feed amount is too large, the pressure of the slag will squeeze the conveyor belt 301 downward, thereby pushing the bearing roller 404 to move downward synchronously. The movable seats 405 at both ends of the bearing roller 404 move downward synchronously along the inner sliding groove of the U-shaped seat 402, driving the connecting plate 406 to move downward together. At the same time, the hinge rod 408 fixed on the movable seat 405 slides along the inner wall of the movable groove 407 on the outer surface of the bearing roller 404, thereby driving the hinged correction roller 403 to deflect around the hinge point of the mounting seat 401, so that the V-shaped angle formed by the correction roller 403 and the bearing roller 404 is reduced. The guiding constraint force of the V-shaped structure pushes the deviated slag back to the center position of the conveyor belt 301, realizing automatic correction. When the slag pressure decreases, the spring telescopic rod 11 at the bottom of the connecting plate 406 releases elastic potential energy, pushing the bearing roller 404 and the movable seat 405 to reset, and the correction roller 403 also returns to its initial angle.

[0064] As the movable seat 405 moves downward, the drive rod 802 fixed on its outer side synchronously drives the rubber piston 803 inside the mounting cylinder 801 to slide along the inner wall of the cavity, causing a change in the air pressure inside the cavity of the mounting cylinder 801. Under the action of the air pressure difference, the lubricating oil in the temporary storage box 16 enters the cavity of the mounting cylinder 801 through the connecting pipe 1 804, and then is evenly sprayed onto the outer surface of the correction roller 403 and the bearing roller 404 through the connecting pipe 2 805 and multiple nozzles on the outer surface, so as to achieve adaptive lubrication of the linkage. The greater the slag pressure and the greater the downward movement of the movable seat 405, the more sufficient the lubricating agent. The one-way valves inside connecting pipe 1 (804) and connecting pipe 2 (805) ensure unidirectional flow of lubricating oil and prevent backflow. When the lubricating oil level in the temporary storage tank 16 is lower than the preset threshold, the flow sensor inside triggers the pump body 5 to start. The pump body 5 draws lubricating oil from the storage tank 15 through the installation pipe 2 (10) and delivers it to the temporary storage tank 16 through the installation pipe 1 (9) and the diversion pipe, thus completing the automatic replenishment of lubricating oil and ensuring continuous and stable lubrication.

[0065] When the slag conveying is completed or the feed amount is reduced, each component gradually resets under the action of the elastic structure spring telescopic rod 11 and the elastic buffer support arm 603. The conveyor belt 301 maintains a uniform speed and waits for the next round of slag to be introduced, forming a continuous and stable conveying cycle.
