Description

Technical Field

[0001] This invention belongs to the field of coal conveyor belt cleaning and recycling technology, and specifically relates to a coal conveyor belt cleaning and recycling device. Background Technology

[0002] In recent years, industries such as thermal power generation and coal transportation have continuously increased their requirements for the cleanliness and environmental protection of coal conveying systems. As a core piece of equipment to ensure belt cleanliness and reduce material loss, coal conveyor belt cleaning devices have been widely used.

[0003] Currently, the space in the corner of the recycling unit of the cleaning device is narrow, making it difficult for the main scraper to reach. Long-term operation can easily cause coal dust to accumulate and clump. The residual coal dust in the corner is easy to scatter and pollute the environment, and will also increase the risk of equipment jamming and wear, reducing the cleaning and recycling efficiency and the service life of the equipment. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the technical problems in the related art.

[0005] To achieve the above objectives, the present invention provides a coal conveyor belt cleaning and recycling device, comprising:

Each of the two strip grooves is provided with a strip push plate. The sides of the two strip push plates facing away from each other are abutted by a plurality of first abutting plates. Each of the plurality of first abutting plates is provided with a forward rotation component and a transmission component. The forward rotation component and the transmission component are used to make the first abutting plates push the strip push plates to flip and push out and clean the accumulated material in the corner. The energy storage mechanism includes a plurality of second abutments disposed on the side of a plurality of first abutments facing away from the strip pusher plate. The plurality of second abutments are drivenly connected to a reverse rotation component, which is used to drive the second abutments to quickly contact the first abutments and quickly push the first abutments to flip. The secondary cleaning mechanism includes a scraper disposed on the side of the strip pusher facing the transmission assembly. The scraper is provided with a reciprocating assembly, which is used to push the scraper to perform secondary cleaning of the material that was not cleaned by the first abutment plate.

[0007] This invention utilizes the synergistic action of a corner cleaning mechanism and an energy storage mechanism to enable the strip pusher plate to push material at a uniform speed and perform rapid knocking and vibration, effectively cleaning up coal dust accumulation in corners that the main scraper cannot reach. This solves the problem of material accumulation and clumping in corners, which can easily cause equipment wear and tear. Furthermore, through the coordinated cleaning of the secondary cleaning mechanism, the cleaning and recycling efficiency and equipment lifespan are significantly improved.

The horizontal push plate is fixedly connected to the telescopic rod.

[0010] Furthermore, a tension spring is provided between the side of the push plate away from the telescopic rod and the inner side of the protective box, and the tension spring is arranged perpendicular to the push plate.

[0011] Furthermore, the reverse rotation assembly includes an inner rotating groove formed in the inner cavity of the outer sleeve on the side away from the telescopic rod, an inner sleeve is rotatably disposed in the inner cavity of the inner rotating groove, and a second oblique arc groove is provided on the inner wall of the inner sleeve, the second oblique arc groove being opposite in direction to the first oblique arc groove; A second guide rod is slidably connected inside the second inclined arc groove. The other end of the second guide rod is fixedly connected to the transmission rod, and the transmission rod passes through the inner sleeve.

[0013] Furthermore, a torsion spring is provided on the outer ring surface of the inner sleeve at the end away from the annular groove. One end of the torsion spring is fixedly connected to the outer wall of the inner sleeve, and the other end of the torsion spring is fixedly connected to the outer sleeve.

[0014] Furthermore, the reverse rotation assembly also includes a retractable rod that is slidably disposed in the inner cavity of the through groove. One end of the retractable rod is fixedly connected to the outer annular surface of the inner sleeve, and the other end of the retractable rod is sleeved outside the second abutment plate.

Detailed Implementation

[0022] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0023] Reference Figure 1 - Figure 10 This is the first embodiment of the present invention. This embodiment provides a coal conveyor belt cleaning and recycling device, which achieves the effect of cleaning the corner material that the main scraper of the scraper cleaning device 10 cannot reach. It includes a corner cleaning mechanism, which includes a scraper cleaning device 10. The scraper cleaning device 10 has strip grooves 11 on both sides of the corner of the recycling unit. Each of the two strip grooves 11 is provided with a strip pusher plate 12. The back of each of the two strip pusher plates 12 is abutted by a plurality of first abutment plates 13. Each of the plurality of first abutment plates 13 is provided with a forward rotation component 14 and a transmission component 15. The forward rotation component 14 and the transmission component 15 are used to make the first abutment plates 13 push the strip pusher plates 12 to flip and push out the accumulated material in the corner for cleaning. The energy storage mechanism includes several second plates 20 disposed on the back of several first plates 13. Each of the several second plates 20 is provided with a reverse rotation component 21. The reverse rotation component 21 is used to drive the second plates 20 to quickly contact the first plates 13 and quickly push the first plates 13 to flip. The secondary cleaning mechanism includes a scraper 30 disposed on the back of the strip pusher 12, and a reciprocating component 31 disposed on the scraper 30. The reciprocating component 31 is used to push the scraper 30 to perform secondary cleaning of the material that was not cleaned by the first abutment 13.

[0024] Specifically, the strip pusher 12 is flipped on the opposite side of the strip groove 11 by an arc-shaped rod (e.g., Figure 3 As shown in the figure, since it is existing technology, its structural principle will not be described in detail here. However, through the cooperation of the forward rotating component 14 and the transmission component 15, the front section of the strip pusher 12 can maintain a constant speed to push out the accumulated material at the inside corner of the scraper cleaning device 10 that could not be carried away by the main scraper. During this process, the reverse rotating component 21 drives the second abutment 20 to rotate in the opposite direction to store energy. Then, when the first abutment 13 has rotated halfway, the energy storage is released, and then it rotates in the opposite direction quickly, so that the second abutment 20 can quickly strike the strip pusher 12, so that the strip pusher 12 can be rotated quickly. At the same time, it can also cause vibration to the strip pusher 12, so that it can shake off some of the attached dust. If the strip pusher 12 fails to carry away all the accumulated material when it rotates, the scraper 30 can push out the remaining accumulated material under the push of the reciprocating component 31.

[0025] Furthermore, the forward rotation assembly 14 includes an outer sleeve 141 fixedly disposed on the back of the first abutment plate 13. The inner cavity of the outer sleeve 141 is provided with a first oblique arc groove 142. A first guide rod 143 is slidably disposed in the inner cavity of the first oblique arc groove 142. A transmission rod 144 is fixedly disposed on the back of the first guide rod 143. The transmission rod 144 is movably disposed through the outer sleeve 141. A telescopic rod 145 is movably disposed through one end of the transmission rod 144. The telescopic rod 145 and the transmission rod 144 mutually limit each other, thereby preventing the transmission rod 144 from rotating when the telescopic rod 145 pushes the transmission rod 144 to move.

[0026] The transmission assembly 15 includes a protective box 151 fixedly installed at the external opening of the strip groove 11. The protective box 151 has a through transverse groove 152 at the upper part of one end of the telescopic rod 145. A T-shaped slide rod 153 is slidably installed in the inner cavity of the through transverse groove 152. A toothed plate 154 is fixedly installed on the upper part of the T-shaped slide rod 153. A half gear 155 is meshed on the upper part of the toothed plate 154. The half gear 155 is fixedly connected to the chain drive shaft in the scraping and cleaning device 10. A horizontal push plate 156 is fixedly installed at the lower part of the toothed plate 154 away from the half gear 155. A tension spring 157 is elastically connected between the horizontal push plate 156 and the side wall of the protective box 151 for resetting.

[0027] The half gear 155 is fixedly connected to the chain drive shaft of the scraping and cleaning device 10, allowing the half gear 155 to rotate along with the chain drive shaft of the scraping and cleaning device 10. This drives the toothed plate 154 to move laterally, which in turn drives the telescopic rod 145 to move. The telescopic rod 145 then drives the transmission rod 144 to move. Fixing plates are provided on both sides of the outer sleeve 141 to secure it (e.g., ...). Figure 4 , 5 As shown), this allows the outer sleeve 141 to be stably positioned within the inner cavity of the strip groove 11.

[0028] In operation, the scraper cleaning device 10 first cleans the material carried on the return path of the coal conveyor belt, and then collects the fallen material through the recovery unit at the bottom of the scraper cleaning device 10 and cleans it through the main scraper. The main scraper (such as...) Figure 1 As shown, the transmission is achieved through a chain and sprockets. Since the half gear 155 is fixedly connected to the sprocket drive shaft in the chain, the half gear 155 will rotate together with the chain drive shaft. When the half gear 155 rotates to the state of meshing with the toothed plate 154, it will drive the toothed plate 154 to move laterally along the through transverse groove 152 in the protective box 151. At this time, the horizontal push plate 156 fixed at the bottom of the toothed plate 154 moves synchronously and stretches the tension spring 157 connected between it and the side wall of the protective box 151, storing elastic potential energy for subsequent reset. Meanwhile, the T-shaped slide bar 153 at the bottom of the toothed plate 154 slides in the cavity of the through transverse groove 152 to ensure the stability of the lateral movement of the toothed plate 154.

[0029] During the movement of the toothed plate 154, it pushes the telescopic rod 145 inside the protective box 151 to move horizontally. Because the telescopic rod 145 and the transmission rod 144 are mutually restrained, the transmission rod 144 is prevented from rotating during movement, allowing the telescopic rod 145 to stably push the transmission rod 144 towards the outer sleeve 141. When the first guide rod 143 at the front end of the transmission rod 144 moves, it slides along the first inclined arc groove 142 inside the outer sleeve 141. Using the inclined trajectory of the first inclined arc groove 142, the lateral thrust of the transmission rod 144 is converted into the rotational force of the outer sleeve 141, thereby causing the first abutment plate 13, which is fixedly connected to the outer sleeve 141, to flip. When the first abutment plate 13 flips, it pushes against the strip-shaped push plate 12, causing the strip-shaped push plate 12 to flip synchronously within the strip groove 11 via the arc rod, pushing out the accumulated material at the inside corner of the scraper cleaning device 10 recovery unit that was not carried away by the main scraper plate at a constant speed.

[0030] As the first abutment plate 13 slowly rotates, the reverse rotation component 21 on the second abutment plate 20 drives the second abutment plate 20 to rotate in the opposite direction to store energy. When the first abutment plate 13 has rotated more than halfway, the reverse rotation component 21 releases the stored energy and drives the second abutment plate 20 to rotate rapidly in the opposite direction, causing it to strike the back of the strip pusher plate 12 quickly. This striking action provides auxiliary thrust for the subsequent rotation of the strip pusher plate 12 and also shakes off dust and fine particles adhering to the surface of the strip pusher plate 12 through vibration, preventing material residue.

[0031] If some material remains uncollected after the strip pusher plate 12 flips over, the scraper plate 30, driven by the reciprocating assembly 31, slides back and forth along the inner side of the strip groove 11 to completely push out the remaining material that the strip pusher plate 12 did not carry away, achieving thorough cleaning of corner materials. When the half gear 155 rotates to the non-meshing tooth section, the horizontal pusher plate 156, under the elastic restoring force of the tension spring 157, drives the toothed plate 154 to move in the opposite direction. The telescopic rod 145, the transmission rod 144, and the first abutment plate 13 are reset in sequence, and the strip pusher plate 12 returns to its original position synchronously, preparing for the next cleaning cycle.

[0032] Example 2 Reference Figure 7 - Figure 10This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides an energy storage mechanism for the coal conveyor belt cleaning and recovery device, which solves the problem of the short pushing distance of the strip pusher 12 at a constant speed. It includes a reverse rotation component 21, which includes an inner rotating groove 211 opened in the inner cavity of the outer sleeve 141 on the side away from the telescopic rod 145. An inner sleeve 212 is rotatably arranged in the inner cavity of the inner rotating groove 211. A second oblique arc groove 213 is provided on the inner wall of the inner sleeve 212. The second oblique arc groove 213 is opposite in direction to the first oblique arc groove 142. A reversing release groove is provided at the end of the second oblique arc groove 213 away from the first oblique arc groove 142. The reversing release groove includes a transverse sliding groove 214 provided at the end of the second oblique arc groove 213 away from the first oblique arc groove 142. The transverse sliding groove 214 is located at the end of the second oblique arc groove 213 away from the second oblique arc groove 213. An annular groove 215 is provided, and the second oblique arc groove 213, the transverse groove 214, and the inner cavity of the annular groove 215 are interconnected. A second guide rod 216 is slidably connected to each of the second oblique arc groove 213, the transverse groove 214, and the inner cavity of the annular groove 215. The back of the second guide rod 216 is fixedly connected to the transmission rod 144. A torsion spring 217 is provided on the outer ring surface of the end of the inner sleeve 212 away from the annular groove 215. The torsion spring 217 is used to store energy and reset the inner sleeve 212. The reverse rotation assembly 21 also includes a through groove 218 formed between the second oblique arc groove 213 and the first oblique arc groove 142. A retraction rod 219 is slidably provided in the inner cavity of the through groove 218. The back of the retraction rod 219 is fixedly connected to the outer ring surface of the inner sleeve 212, and the retraction rod 219 is sleeved outside the second abutment plate 20. A return spring is provided between the second abutment plate 20 and the inner bottom wall of the retraction rod 219.

[0033] Specifically, the length of the through groove 218 penetrating the outer sleeve 141 is two-thirds of the circle. This ensures that the retractable rod 219 can rotate without splitting the outer sleeve 141 in half, thus affecting its stability. The retractable rod 219 is connected to the second abutment 20 by a spring. Under normal conditions, the second abutment 20 retracts into 219 under the action of the spring. At the same time, a notch is opened on the back of the first abutment 13 at the position of the through groove 218 (e.g., Figure 10 As shown), the depth of the notch is greater than the length of the second abutment 20 exposed from the retracting rod 219, but less than the length of the second abutment 20 fully extended from the retracting rod 219. Thus, when the inner sleeve 212 rapidly reverses under the action of the torsion spring 217, the centrifugal force causes the second abutment 20 to be thrown out from the retracting rod 219, and the thrown second abutment 20 can hit the back of the first abutment 13.

[0034] In use, firstly, after the scraping and cleaning device 10 is started, the chain drive shaft drives the half gear 155 to rotate, driving the toothed plate 154 to move laterally along the through transverse groove 152 of the protective box 151. The T-shaped slide bar 153 slides synchronously to ensure stability. The horizontal push plate 156 stretches the tension spring 157 to store energy. The toothed plate 154 pushes the telescopic rod 145 to drive the transmission rod 144 to move towards the outer sleeve 141.

[0035] When the transmission rod 144 moves, its front end first guide rod 143 slides along the first oblique arc groove 142 inside the outer sleeve 141, converting the lateral thrust into the rotational force of the outer sleeve 141, causing the first abutment 13 to flip. At the same time, the second guide rod 216 fixed to the back of the transmission rod 144 slides synchronously along the second oblique arc groove 213 on the inner wall of the inner sleeve 212. Since the second oblique arc groove 213 is in the opposite direction to the first oblique arc groove 142, the sliding of the second guide rod 216 will drive the inner sleeve 212 to rotate in the opposite direction in the inner rotating groove 211, and the torsion spring 217 on the outer ring surface of one end of the inner sleeve 212 will be torsionally stored. When the second guide rod 216 slides to the end of the second oblique arc groove 213, it will enter the transverse sliding groove 214 and finally slide into the annular sliding groove 215. At this time, the first guide rod 143 has completed the stroke in the first oblique arc groove 142, the first abutment plate 13 has flipped more than halfway, and the inner sleeve 212 has stored enough elastic potential energy under the torsion action of the torsion spring 217.

[0036] When the second guide rod 216 is fully inserted into the annular groove 215, its limiting effect on the second inclined arc groove 213 is released, and the torsion spring 217 quickly releases its stored energy, driving the inner sleeve 212 to rotate rapidly in the opposite direction. The centrifugal force generated by the rapid reversal of the inner sleeve 212 throws the second abutment 20 inside the retracting rod 219 outward. It should be noted that the return spring between the retracting rod 219 and the second abutment 20 is stretched at this time. Because the back of the first abutment 13 has a notch of a specific depth corresponding to the position of the through groove 218, the thrown second abutment 20 strikes the back of the first abutment 13. This striking action provides a rapid thrust to the first abutment 13, pushing it to rapidly rotate to a larger angle. At this time, the first oblique arc groove 142 will rotate rapidly, thereby pushing the transmission rod 144 to move rapidly. Due to the extensibility between the telescopic rod 145 and the transmission rod 144, this process is not affected. It should be noted that when the transmission rod 144 moves forward rapidly, it will drive the second guide rod 216 to move rapidly as well. This moving distance is less than the width of the annular groove 215 (e.g., Figure 10 As shown), this avoids the annular chute 215 from blocking it, and the rapid flipping of the first abutment plate 13 will increase the pushing distance, while the generated vibration force can shake off the dust attached to the surface of the strip push plate 12, avoiding material residue.

[0037] It should be further explained that the stroke length of the telescopic rod 145 is greater than or equal to the stroke length of the toothed plate 154 minus the total horizontal displacement of the second guide rod 216; and when the tension spring 157 is not stretched, the stroke length of the telescopic rod 145 retracting into one end of the telescopic rod 145 is less than or equal to the stroke length of the telescopic rod 145. This ensures that there is sufficient telescopic stroke between the telescopic rod 145 and the transmission rod 144, allowing the second abutment plate 20 to drive the outer sleeve 141 to rotate through the first abutment plate 13, ultimately pushing the transmission rod 144 to move quickly; and it also ensures that the telescopic rod 145 can normally push the transmission rod 144 to the second guide rod 216 into the annular groove 215 under the drive of the horizontal push plate 156.

[0038] Under the rapid push of the first abutment plate 13, the strip pusher 12 pushes the accumulated material at the inside corner of the scraping and cleaning device 10 to the area that the main scraper can scrape. If there is still residual material due to falling during the flipping, the scraper 30 slides back and forth along the inner side of the strip groove 11 under the drive of the reciprocating assembly 31 to complete the secondary cleaning. When the half gear 155 rotates to the non-meshing tooth section, the horizontal pusher 156 drives the tooth plate 154 to move in the opposite direction under the reset force of the tension spring 157. The telescopic rod 145 and the transmission rod 144 are reset in sequence, and the second guide rod 216 slides in the opposite direction along the annular slide groove 215, the horizontal slide groove 214, and the second oblique arc groove 213. It should be noted here that... At this time, the torsion spring 217 will drive the inner sleeve 212 to reset, and the opening of the transverse slide groove 214 can be aligned with the movement of the second guide rod 216 to prevent it from failing to enter the transverse slide groove 214. During this return process, the inner sleeve 212 rotates in the opposite direction under the drive of the second guide rod 216, and the torsion spring 217 recharges. At this time, the second abutment plate 20 retracts inward under the action of the spring, so that it can smoothly pass through the notch on the first abutment plate 13 to reset. At this time, the first abutment plate 13 and the strip push plate 12 return to their positions synchronously, and then prepare for the next long-distance pushing cycle.

[0039] Example 3 Reference Figure 6 - Figure 7 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a secondary cleaning mechanism for the coal conveyor belt cleaning and recycling device, which solves the problem of incomplete cleaning caused by the accumulation of material falling when the front section of the strip pusher plate 12 is flipped. It includes a reciprocating assembly 31, including a fixed seat 311 fixedly installed on the bottom surface of the inner cavity of the protective box 151. A horizontal push rod 312 fixedly connected to the scraper plate 30 is movably installed through the middle of the fixed seat 311. Pull ropes 313 are provided on both sides of the upper part of the horizontal push rod 312 away from the fixed seat 311. The other end of the pull rope 313 is fixedly connected to the back of the first abutment plate 13. A compression spring 314 is elastically connected between the horizontal push rod 312 and the fixed seat 311. The compression spring 314 is used to reset the horizontal push rod 312 and the scraper plate 30.

[0040] Specifically, the height of the scraper 30 is less than the distance between the lowest point of the outer sleeve 141 and the bottom surface of the inner cavity of the protective box 151, so that the outer sleeve 141 does not affect the pushing out of the scraper 30, and the length of the scraper 30 is the same as the length of the first abutment plate 13.

[0041] In use, firstly, after the scraping and cleaning device 10 is started, the chain drive shaft drives the half gear 155 to rotate, driving the toothed plate 154 to move laterally along the through transverse groove 152 of the protective box 151. The T-shaped slide bar 153 ensures the stability of the movement. The horizontal push plate 156 stretches the tension spring 157 to store energy. The toothed plate 154 pushes the telescopic rod 145 to drive the transmission rod 144 to move towards the outer sleeve 141. During the movement of the transmission rod 144, the first guide rod 143 at the front end moves along the first guide rod of the outer sleeve 141. The inclined arc groove 142 slides, causing the first abutment plate 13 to flip. When the first abutment plate 13 flips, the two pull ropes 313 fixed on its back are pulled synchronously. The pull ropes 313 pull the horizontal push rod 312 to move along the fixed seat 311 towards the strip groove 11. The compression spring 314 between the horizontal push rod 312 and the fixed seat 311 is compressed and stored. The end of the horizontal push rod 312 away from the pull rope 313 is fixedly connected to the scraper 30. Therefore, the scraper 30 extends into the strip groove 11 synchronously with the horizontal push rod 312.

[0042] Since the length of the scraper 30 is the same as that of the first abutment plate 13 and its height is less than the distance between the lowest point of the outer sleeve 141 and the bottom surface of the inner cavity of the protective box 151, the outer sleeve 141 will not interfere with the movement of the scraper 30. At the same time, when the second abutment plate 20 causes the first abutment plate 13 to flip quickly, the rapid flipping of the first abutment plate 13 will quickly push the scraper 30 out through the pull rope 313 and the horizontal push rod 312, thereby quickly pushing the falling material. This allows the scraper 30 to completely push the accumulated material falling from the strip push plate 12 and the residual material that has not been completely pushed out into the range of action of the main scraper of the recycling unit. When the half gear 155 rotates to the non-meshing tooth section, the horizontal push plate 156, under the restoring force of the tension spring 157, drives the tooth plate 154, the telescopic rod 145, and the transmission rod 144 to return to their original positions in reverse order. The first abutment plate 13 then flips back to its original position, and the tension of the pull rope 313 is gradually released. At this time, the compression spring 314 releases its stored energy, pushing the horizontal push rod 312 to move quickly in the opposite direction. The scraper 30 is simultaneously retracted to its initial position, completing the cleaning.
