Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mine belt conveyor, in particular to a mine belt conveyor capable of reducing slag residue and a use method thereof. BACKGROUND

[0002] The mine belt conveyor is widely used in long-distance transfer operation of coal, ore and other bulk materials. The core working component is the conveying belt. The conveying belt surface is prone to stick to slag particles due to the influence of the harsh working conditions of high wear, high humidity, flammability and static electricity in the mine.

[0003] A conveying belt surface cleaning device is disclosed in a patent with the title of "a conveying belt surface cleaning device" (patent application number: CN202323511315.6). The trigger lever on the support frame acts on the cleaning plate. One end of the cleaning plate overcomes the elastic force of the elastic return device and rotates upward. The other end is in contact with the surface of the conveying belt. Then the residual aggregate on the surface of the conveying belt is scraped off. In the actual cleaning process, the same position of the cleaning plate is in contact with the conveying belt continuously. The residual particles stick to the contact area of the cleaning plate and the conveying belt to form secondary slag accumulation. Not only does it reduce the cleanliness of single cleaning, but also causes scratches on the surface of the conveying belt due to repeated extrusion of the slag accumulation, which affects the use efficiency of the mine belt conveyor.

[0004] Therefore, it is necessary to provide a mine belt conveyor capable of reducing slag residue and a use method thereof to solve the above problems. SUMMARY

[0005] The present application aims to provide a mine belt conveyor capable of reducing slag residue and a use method thereof to solve the problem that the same position of the cleaning plate is in contact with the conveying belt continuously in the actual cleaning process. The residual particles stick to the contact area of the cleaning plate and the conveying belt to form secondary slag accumulation. Not only does it reduce the cleanliness of single cleaning, but also causes scratches on the surface of the conveying belt due to repeated extrusion of the slag accumulation, which affects the use efficiency of the mine belt conveyor.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical scheme: a mine belt conveyor capable of reducing slag residue, comprising: A conveying belt is arranged on a conveying frame and used for conveying mine materials. A cleaning mechanism is arranged below the conveying belt and comprises a synchronous cylinder, a plurality of contact strips and a plurality of cylinder grooves arranged on the ring wall of the synchronous cylinder. The contact strips are elastically hinged at the corresponding cylinder grooves and adaptively swing and adhere to the conveying belt to scrape off the materials when entering the cleaning area by being extruded by the conveying belt. The contact strips shake off the attached slag by elastic return when leaving the cleaning area. An interception net is arranged in the cylinder groove and used for matching the suction action of the synchronous cylinder and the cylinder groove to intercept coal slag particles and allow dust to pass through. The arc plate, located in the lower half of the synchronous cylinder, is used to concentrate the suction force on the cleaning area of ​​the upper half of the synchronous cylinder, while blocking the suction in the lower half of the synchronous cylinder to help the intercepted coal slag particles fall off.

[0007] Preferably, a transmission mechanism is provided between the contact strip and the intercepting net. The transmission mechanism includes a through plate, an arc-shaped slide, and a plate rod. It is used to drive the intercepting net to swing after the contact strip swings to a preset angle during the process of tilting and retracting the contact strip into the cylinder groove, and to drive the intercepting net to shake when the contact strip elastically resets.

[0008] Preferably, the cleaning mechanism operates synchronously with the conveyor belt via a synchronization component, which includes a shaft, a first pulley, a second pulley, and a timing belt.

[0009] Preferably, the elastic hinge between the contact strip and the cylinder groove is achieved by a torsion spring.

[0010] Preferably, an elastic sheet is provided between the intercepting net and the cylindrical groove, the elastic sheet being used to provide elastic force for the swinging and resetting of the intercepting net.

[0011] Preferably, rollers are rotatably provided at both ends of the arc plate, and the rollers are attached to the inner wall of the synchronizing cylinder.

[0012] Preferably, both ends of the arc plate have a pushing component that drives the interception net to shake rapidly. The pushing component includes multiple evenly distributed arc strips, and there is a gap between each adjacent arc strip.

[0013] Preferably, the length of the contact strip is greater than the width of the conveyor belt.

[0014] Preferably, the arc plate is fixed to the transport frame by a shaft tube and a connecting rod, and the shaft tube connects the synchronization cylinder to the factory's negative pressure suction pipeline.

[0015] This invention also discloses a method for using a mining belt conveyor that reduces slag residue. Applied to the aforementioned mining belt conveyor with reduced slag residue, the method further includes the following operational steps: S1: Start conveying and synchronous cleaning. Start the conveyor to transport the ore and drive the cleaning mechanism to run synchronously. After the scraping part of the cleaning mechanism enters the cleaning area, it scrapes off the slag by adhering to the conveying surface. S2: Slag interception and dust extraction. The slag is intercepted by the interception component and the dust is extracted. The suction force is concentrated on the cleaning area. S3: Reset and Shaking and Continuous Operation. After the scraper leaves the cleaning area, it generates a shaking motion through elastic reset, which in turn drives the interceptor to shake, shaking off the slag particles attached to itself and the interceptor to carry out continuous operation.

[0016] The technical effects and advantages of this invention are as follows: 1. This invention, by setting up a cleaning mechanism, a synchronization component and other structures, utilizes the power of the conveyor to automatically complete the switching of the contact strip and shake off residual slag, preventing secondary adhesion. At the same time, relying on the elastic linkage design, it adaptively swings bidirectionally with the force direction of the conveyor belt in both forward and reverse directions to complete the cleaning, thereby improving the efficiency of the mining belt conveyor. 2. The side plate and contact strip are adaptively tilted by the squeezing and limiting effect of the conveyor belt, which does not affect the continuous rotation of the synchronous drum, and the contact strip in the cleaning state remains attached to the conveyor belt to ensure the force of pushing and scraping cleaning. 3. By setting up structures such as arc plates, the suction force is applied to the dust generation location, ensuring timely capture of the raised dust, while ensuring that the suction force is more concentrated and efficient. In addition, the blocking effect of the arc plates allows the coal slag particles on the corresponding interception net to fall off naturally. 4. By setting up structures such as elastic plates and transmission mechanisms, the side plates swing with the force of the conveyor belt as the driving source, which drives the interception net to produce a shaking effect, causing the residual slag to loosen and fall off. 5. The elastic sheet and the torsion spring form a reset elastic system to ensure that the contact bar resets quickly, thereby generating a strong shaking effect, which causes the residual coal slag on the contact bar to fall off quickly. 6. When the interception net swings with the transmission mechanism, the orientation of its surface micropores is dynamically adjusted synchronously, breaking the suction range limitation of the fixed interception net, thereby expanding the suction coverage area and improving the dust capture rate. 7. A transmission mechanism is set up to form a "sliding first, then contact and driving" action sequence, so that the interception net will not swing excessively and ensure stable use; 8. By setting up structures such as the pushing component, the interception net has two modes of vibration: the transmission mechanism linkage vibration and the pushing component contact vibration. The dual vibrations complement each other, greatly improving the slag removal efficiency. 9. When half of the trough is exposed, the shaking causes the dust to be sucked away in time. When the trough is completely covered by the arc plate, the suction negative pressure disappears, and the shaking causes the coal slag particles to fall quickly under the action of gravity without dust.

Detailed Implementation

[0028] This invention provides, for example Figures 1-10 The mining belt conveyor shown includes a conveyor frame 1 fixed on the ground. Two rollers 22 are rotatably mounted at both ends of the conveyor frame 1, and a conveyor belt 2 is fitted between the two rollers 22. The conveyor belt 2 consists of a core skeleton and a cover rubber layer, meeting the requirements for flame retardancy, antistatic properties, wear resistance, and tear resistance in underground mining operations. The core skeleton uses high-carbon steel wire rope, which has extremely high tensile strength and tear resistance, excellent impact resistance, and a long service life. The cover rubber layer uses neoprene rubber with added flame retardants, possessing both wear resistance and flame retardant properties, effectively coping with high-wear and flammable working environments, and can be adjusted according to specific usage conditions.

[0029] The transport frame 1 is equipped with a drive device 25 that drives the transport belt 2. The drive device 25 includes a drive motor, a drive pulley, a driven pulley, and a belt. The driven pulley is fixedly mounted on one of the rollers 22, the drive motor is fixedly mounted on the transport frame 1, and the drive pulley is fixedly mounted on the drive shaft of the drive motor. The drive pulley and the driven pulley are connected by belt drive. When the drive motor is running, the corresponding roller 22 is driven to rotate through the drive pulley, the driven pulley, and the belt. With the cooperation of the other roller 22, the transport belt 2 runs, thereby transporting the ore.

[0030] Considering that some residual slag usually adheres to the conveyor belt 2 when transporting ore, if it is not cleaned in time, it will affect the conveying efficiency of the conveyor. At the same time, the conveyor belt 2 may reverse due to temporary relocation, etc. In order to achieve efficient cleaning of residual slag, a cleaning mechanism is set below the conveyor belt 2. The cleaning mechanism includes a synchronous cylinder 3. The axial direction of the synchronous cylinder 3 is consistent with the width direction of the conveyor belt 2, and one of the rollers 22 drives the synchronous cylinder 3 to rotate through the synchronous assembly.

[0031] The annular wall of the synchronization cylinder 3 is provided with a groove 4, which penetrates the inner and outer surfaces of the synchronization cylinder 3 and is connected to the inner cavity of the synchronization cylinder 3. Multiple grooves 4 are provided and are evenly distributed around the annular wall of the synchronization cylinder 3. The groove 4 includes an outer groove section 401 and an inner groove section 402. The outer groove section 401 is close to the outer surface of the synchronization cylinder 3. The length and width of the outer groove section 401 are larger than the length and width of the inner groove section 402, respectively. Side rods 7 are fixedly installed at both ends of the outer groove section 401. The side rods 7 are located in the middle of the inner wall of the end of the outer groove section 401. The ends of the two side rods 7 that are close to each other are rotatably connected to side plates 8. A contact strip 10 is fixedly installed between the two side plates 8. The length of the contact strip 10 is slightly larger than the width of the conveyor belt 2 to ensure the cleaning range.

[0032] A torsion spring 9 is fitted on the side rod 7. One end of the torsion spring 9 is fixedly connected to the side rod 7, and the other end of the torsion spring 9 is fixedly connected to the side plate 8. The elastic support force of the torsion spring 9 is calibrated and set to provide a stable preload force, ensuring that the side plate 8 and the contact strip 10 maintain a preset posture when there is no external force, and will not swing randomly due to the vibration of the conveyor belt or the bumps of the equipment operation.

[0033] When no external force is applied, under the elastic support force of the torsion spring 9, the end of the side plate 8 away from the side rod 7 extends out of the outer groove section 401 and is in a vertical distribution state with the bottom of the outer groove section 401 (refer to...). Figure 8Meanwhile, since the side rod 7 is located in the middle of the outer trough section 401, it can adaptively swing to both sides of the outer trough section 401 according to the force direction of the forward and reverse rotation of the conveyor belt 2. No matter which side it swings to, it can tilt and retract towards the inside of the outer trough section 401. Furthermore, since the length and width dimensions of the outer trough section 401 are larger than those of the inner trough section 402, the side plate 8, contact strip 10, etc. only contact the inner wall of the outer trough section 401 and do not collide or interfere with the inner trough section 402 and its internal structure.

[0034] The contact strip 10 is made of highly elastic and wear-resistant polyurethane material, which combines excellent resilience, wear resistance and tear resistance. It can not only adhere tightly to the surface of the conveyor belt 2 through its own elasticity to efficiently scrape off the sticky slag residue, but also withstand the repeated friction and impact of slag particles, greatly extending the service life of the contact strip 10. At the same time, the polyurethane material has good antistatic properties, which can prevent the static electricity generated by friction from adsorbing slag dust, preventing dust from accumulating on the surface of the contact strip 10 and affecting the cleaning effect, and can be regularly inspected and maintained by operators. Moreover, the shape of the contact strip 10 can be adjusted according to specific use, such as a triangular prism shape. The edges of the triangular prism contact strip 10 can enhance the scraping force on stubborn slag.

[0035] In specific configuration, the synchronization assembly includes a shaft 14, a first pulley 21, a second pulley 23, and a timing belt 24. The shaft 14 is rotatably mounted on the transport frame 1, and the timing cylinder 3 is fixedly connected to the shaft 14. The timing cylinder 3 and the shaft 14 are concentrically arranged. The first pulley 21 is fixedly mounted on the shaft 14, and the second pulley 23 is fixedly mounted on one of the rollers 22. The first pulley 21 and the second pulley 23 are connected by the timing belt 24. When the transport belt 2 is running, the roller 22 rotates, and drives the shaft 14 to rotate through the second pulley 23, the first pulley 21, and the timing belt 24, thereby causing the timing cylinder 3 to rotate synchronously. That is, the cleaning mechanism and the transport machine operate synchronously, ensuring convenient operation and synchronous cleaning.

[0036] The synchronization component is equipped with a protective cover (not shown in the figure) to ensure safety during use and prevent it from being affected by dust and other factors.

[0037] In practice: Operating Condition 1: Synchronous drum 3 rotates clockwise, and the bottom end of conveyor belt 2 moves from right to left (refer to...). Figure 8When the contact strip 10 is not in contact with the conveyor belt 2, under the elastic support force of the torsion spring 9, the side plate 8 extends out of the outer groove section 401 and is vertically distributed with the bottom of the outer groove section 401. The contact strip 10 is also located outside the outer groove section 401. As the synchronous drum 3 rotates, the contact strip 10, which is located in the upper left position, begins to contact the conveyor belt 2 and pushes and scrapes the lower surface of the bottom end of the conveyor belt 2. The elastic support force of the torsion spring 9 keeps the contact strip 10 tightly attached to the conveyor belt 2, ensuring the force of the pushing and scraping cleaning. At the same time, under the squeezing and limiting action of the conveyor belt 2, the side plate 8 and the contact strip 10 swing counterclockwise and move towards the corresponding outer groove section 401. The internal tilting and recovery process continues to push and scrape the lower surface of the conveyor belt 2 during the tilting process. When the belt rotates to the upper right position, the return force of the torsion spring 9 causes the side plate 8 and the contact strip 10 to gradually return to their original positions. At the moment when the contact strip 10 disengages from the conveyor belt 2, the side plate 8 and the contact strip 10 quickly return to their original positions and vibrate, causing the residual slag on the contact strip 10 to fall off, preventing the residual slag from contacting the conveyor belt 2 again during subsequent cleaning, ensuring the cleaning effect and reducing wear. Then, the next contact strip 10 contacts the conveyor belt 2 and, in coordination with the movement of the conveyor belt 2, repeats the above steps to complete the continuous and sustained cleaning of the conveyor belt 2.

[0038] Operating Condition 2: Synchronous drum 3 rotates counterclockwise, and the bottom end of conveyor belt 2 moves from left to right (refer to...). Figure 8 , Figure 9 When the contact strip 10 is not in contact with the conveyor belt 2, under the elastic support force of the torsion spring 9, the side plate 8 extends out of the outer groove section 401 and is vertically distributed with the bottom of the outer groove section 401, and the contact strip 10 is also located outside the outer groove section 401; as the synchronous drum 3 rotates, the contact strip 10, which is now in the upper right position, begins to contact the conveyor belt 2 and pushes and scrapes the lower surface of the bottom end of the conveyor belt 2, and the elastic support force of the torsion spring 9 keeps the contact strip 10 tightly attached to the conveyor belt 2, ensuring the force of pushing and scraping cleaning; at the same time, under the squeezing and limiting action of the conveyor belt 2, the side plate 8 and the contact strip 10 swing clockwise and tilt towards the inside of the corresponding outer groove section 401. The conveyor belt 2 is tilted and scraped at its bottom surface during the tilting process. When it rotates to the upper left position, the return force of the torsion spring 9 causes the side plate 8 and the contact strip 10 to gradually return to their original positions. At the moment when the contact strip 10 disengages from the conveyor belt 2, the side plate 8 and the contact strip 10 quickly return to their original positions and vibrate, causing the residual slag on the contact strip 10 to fall off, preventing the residual slag from contacting the conveyor belt 2 again during subsequent cleaning, thus ensuring the cleaning effect and reducing wear. Then, the next contact strip 10 contacts the conveyor belt 2 and continues cleaning in coordination with the movement of the conveyor belt 2. The above steps are repeated to complete the continuous cleaning of the conveyor belt 2.

[0039] In summary, this invention, by setting up a cleaning mechanism and synchronization components, utilizes the power of the conveyor to automatically switch the contact strip 10 and shake off residual slag, preventing secondary adhesion. At the same time, relying on the elastic linkage design, it adaptively swings bidirectionally with the force direction of the conveyor belt 2 in both forward and reverse directions to complete the cleaning, thereby improving the utilization efficiency of the mining belt conveyor.

[0040] In addition, the side plate 8 and the contact strip 10 are adaptively tilted by the squeezing and limiting effect of the conveyor belt 2, which does not affect the continuous rotation of the synchronous cylinder 3, and the contact strip 10 in the cleaning state remains attached to the conveyor belt 2 to ensure the force of pushing and scraping cleaning.

[0041] Considering the significant dust generated during the cleaning process, a through hole 301 is provided at the end of the synchronous cylinder 3 furthest from the shaft 14 to facilitate dust control. The through hole 301 is concentrically distributed with the synchronous cylinder 3, and a shaft tube 15 is rotatably installed inside the through hole 301. The shaft tube 15 is fixed on the conveyor frame 1, maintaining a fixed position, and is connected to the inner cavity of the synchronous cylinder 3 and the factory's negative pressure suction pipe. Simultaneously, an intercepting net 6 is installed inside the inner groove section 402. The intercepting net 6 has several micro-holes with suitable inner diameters to intercept coal slag particles, while dust can pass through the micro-holes. When the contact strip 10 contacts the conveyor belt 2 and pushes and scrapes the lower surface of the bottom end of the conveyor belt 2, the dust generated by the pushing and scraping is sucked up by the shaft tube 15, the inner cavity of the synchronous cylinder 3, and the cylinder groove 4, while the coal slag particles are intercepted by the intercepting net 6.

[0042] A rubber sealing ring and other structures are provided between the shaft tube 15 and the through hole 301 to reduce wear and ensure sealing.

[0043] Furthermore, considering that the area near the synchronous cylinder 3 and the conveyor belt 2 is the cleaning zone, and the dust is mainly concentrated in the cleaning zone, i.e., the upper half of the synchronous cylinder 3, an arc plate 16 is provided in the lower half of the synchronous cylinder 3 to achieve timely and concentrated suction. A connecting rod 17 is fixedly connected to the arc plate 16, and the top end of the connecting rod 17 is fixedly connected to the shaft tube 15. The shaft tube 15 and the connecting rod 17 are both made of high-strength materials such as stainless steel to ensure that the position of the arc plate 16 is fixed. Rollers 19 are rotatably provided at both ends of the arc plate 16. The rollers 19 are attached to the inner wall of the synchronous cylinder 3 and rotate adaptively when the synchronous cylinder 3 rotates. At the same time, a protective gap 20 is formed between the outer arc surface of the arc plate 16 and the inner wall of the synchronous cylinder 3. The rollers 19 contact the inner wall of the synchronous cylinder 3 and form a protective gap 20 to reduce wear and ensure that the protective gap 20 is not affected by suction.

[0044] Specifically, since the arc plate 16 is located in the lower half of the synchronous cylinder 3, the suction force mainly acts on the upper half of the synchronous cylinder 3, i.e. the cleaning zone, to avoid the suction airflow being dispersed and lost in the lower half of the synchronous cylinder 3, ensuring timely capture of the raised dust, and at the same time, the suction force is more concentrated and efficient.

[0045] When the trough 4 rotates to the upper half of the synchronous drum 3, it is close to the conveyor belt 2 and can suck up dust. The intercepting net 6 intercepts the coal slag particles, which adhere to the intercepting net 6 due to suction. As the trough 4 continues to rotate, when it reaches the lower half of the synchronous drum 3, it aligns with the arc plate 16. Due to the obstruction of the arc plate 16, there is no suction at the trough 4, causing the coal slag particles on the intercepting net 6 to fall off naturally. A collection box is placed under the conveyor frame 1 to collect the fallen coal slag particles for later use.

[0046] The roller 19 is made of high-density wear-resistant nylon material and is fitted with a wear-resistant and anti-static rubber sleeve. This not only enhances the fit and sealing with the inner wall of the synchronization cylinder 3, but also prevents dust from accumulating on the surface of the roller 19 due to static electricity through its own anti-static properties. The roller 19 is regularly inspected and maintained by the operator.

[0047] In summary, by setting up structures such as the arc plate 16, the suction force is applied to the dust generation location, ensuring timely capture of the raised dust, while ensuring that the suction force is more concentrated and efficient. Furthermore, the blocking effect of the arc plate 16 allows the coal slag particles on the corresponding interception net 6 to fall off naturally.

[0048] In actual production, the end of the synchronous cylinder 3 near the shaft tube 15 is set as a detachable cover plate structure. The cover plate and the cylinder are sealed and connected by flange bolts, which facilitates the assembly of the arc plate 16, etc. Afterwards, the operators only need to remove the detachable end cover plate to inspect and maintain the roller 19, etc.

[0049] Considering that relying solely on the natural fall of coal slag particles would leave residue inside the micropores of the interception net 6, to reduce this residue, elastic sheets 5 are fixedly connected to both sides of the interception net 6. The elastic sheets 5 are made of rubber and have a certain degree of elasticity. The elastic sheets 5 are distributed along the axial direction of the synchronous cylinder 3 and are fixedly connected to the inner wall of the inner groove section 402. Meanwhile, the interception net 6 has a rigid sheet structure and sufficient strength for use. Due to the presence of the elastic sheets 5, the interception net 6 can swing when subjected to external forces.

[0050] A transmission mechanism is provided between the interceptor net 6 and the corresponding elastic sheet 5. The transmission mechanism includes a through plate 11, an arc-shaped slide 12, and a plate rod 13. The through plate 11 is fixedly connected to the interceptor net 6 and penetrates the upper and lower surfaces of the interceptor net 6. At the same time, the joint between the through plate 11 and the interceptor net 6 is reinforced to ensure its strength. The arc-shaped slide 12 is opened on one end of the through plate 11 near the outer groove section 401. The arc length of the arc-shaped slide 12 is appropriate. The plate rod 13 is slidably disposed inside the arc-shaped slide 12 and is fixedly connected to the side plate 8. The plate rod 13 is located on the side of the side rod 7 facing away from the corresponding contact strip 10 (refer to...). Figure 9 ).

[0051] When the side plate 8 and the contact strip 10 swing due to the squeezing and limiting effect of the conveyor belt 2, they will cause the plate rod 13 to swing. When the plate rod 13 slides to its end inside the arc-shaped slide 12, it will cause the through plate 11 to swing. With the cooperation of the elastic sheet 5, the intercepting net 6 swings synchronously. After the side plate 8 and the contact strip 10 are reset, the intercepting net 6 is reset synchronously, thereby producing a shaking effect, which makes the residual coal slag particles loose.

[0052] By setting up structures such as the elastic sheet 5 and the transmission mechanism, the side plate 8 swings with the force of the conveyor belt 2 as the driving source, which drives the interception net 6 to produce a shaking effect, causing the residual slag to loosen and fall off.

[0053] Furthermore, the elastic sheet 5 and the torsion spring 9 form a reset elastic system to ensure that the contact bar 10 is quickly reset, thereby generating a strong shaking effect, causing the residual coal slag on the contact bar 10 to fall off quickly.

[0054] Furthermore, as the intercepting net 6 swings with the transmission mechanism, the orientation of its surface micropores is dynamically adjusted synchronously, breaking the suction range limitation of the fixed intercepting net 6, thereby expanding the suction coverage area and improving the dust capture rate.

[0055] When the side plate 8 and the contact strip 10 swing and tilt inwards and retract into the outer groove section 401, the swing angle of the side plate 8 is close to 90°, and the corresponding swing angle of the plate rod 13 is the same. In the initial swing of the plate rod 13, the plate rod 13 only slides inside the arc-shaped slide 12 and does not drive the through plate 11 to swing. Only after the plate rod 13 swings to a certain angle will it abut against the end of the arc-shaped slide 12 and drive the through plate 11 to swing, forming a "sliding first, then abutting and driving" action sequence, so that the interception net 6 will not swing excessively and ensure stable use.

[0056] Furthermore, at both ends of the arc plate 16, near the rollers 19, a pushing assembly is provided. The pushing assembly includes multiple arc strips 18, which are fixedly connected to the outer arc surface of the arc plate 16. The multiple arc strips 18 are evenly distributed, and there is a certain gap between each adjacent arc strip 18. When the inner end of the through plate 11 (the end near the axis of the synchronous cylinder 3) contacts the arc strip 18, the through plate 11 will swing, and the intercepting net 6 will swing synchronously. When the inner end of the transport frame 1 is located in the gap between two arc strips 18, the through plate 11 will reset, and the intercepting net 6 will reset synchronously. This process is repeated multiple times, and the intercepting net 6 shakes rapidly, which facilitates the falling of residual coal slag particles.

[0057] Specifically, since the pushing component is close to the roller 19, when the cylinder trough 4 rotates to the roller 19, the inner end of the corresponding through plate 11 can cooperate with the pushing component. At this time, half of the cylinder trough 4 is not blocked by the arc plate 16 and is still in the area that can be suctioned. At this time, the dust raised by the rapid shaking of the interception net 6 can be quickly sucked away from the cylinder trough 4. Then, the cylinder trough 4 is completely blocked by the arc plate 16 and loses its suction effect. The coal slag particles fall quickly under the action of gravity without raising dust.

[0058] Furthermore, a pushing component can also be set at the bottom of the outer arc surface of the arc plate 16 to ensure the frequency of the interception net 6 shaking.

[0059] Furthermore, the contact area between the through plate 11 and the arc strip 18 is equipped with a ball bearing structure to reduce wear.

[0060] By incorporating structures such as the pushing component, the interceptor net 6 combines two modes: vibration via the transmission mechanism and vibration via the pushing component. These two vibration modes complement each other, significantly improving the slag removal efficiency.

[0061] When half of the trough 4 is exposed, the shaking causes the dust to be sucked away in time. When the trough 4 is completely blocked by the arc plate 16, the suction negative pressure disappears, and the shaking causes the coal slag particles to fall quickly under the action of gravity without dust.

[0062] The drive unit 25 and other structures are connected to a mine-specific explosion-proof power supply and are integrated with a PLC programmable controller. The PLC system is linked with the limit switches, speed sensors and overload protection modules of the conveyor, which can realize the forward and reverse switching, speed adjustment and start and stop control of the conveyor belt 2. The site is equipped with a mine explosion-proof control box, which supports manual / automatic mode switching, which makes it easy for operators to flexibly adjust the operating parameters according to the amount of ore conveyed, and meet the control needs of different working conditions such as temporary transfer, maintenance and repair. At the same time, it will automatically stop and issue a warning when the equipment has faults such as speed mismatch or overload.

[0063] This invention also discloses a method for using a mining belt conveyor that reduces slag residue. Applied to the aforementioned mining belt conveyor with reduced slag residue, the method further includes the following operational steps: S1: Start conveying and synchronous cleaning. Start the conveyor to transport the ore and drive the cleaning mechanism to run synchronously. After the scraping part of the cleaning mechanism enters the cleaning area, it scrapes off the slag by adhering to the conveying surface. S2: Slag interception and dust extraction. The slag is intercepted by the interception component and the dust is extracted. The suction force is concentrated on the cleaning area. S3: Reset and Shaking and Continuous Operation. After the scraper leaves the cleaning area, it generates a shaking motion through elastic reset, which in turn drives the interceptor to shake, shaking off the slag particles attached to itself and the interceptor to carry out continuous operation.
