Description

Technical Field

[0001] The embodiments disclosed herein belong to the technical field of feeding devices, specifically relating to a thermal automated production feeding device. Background Technology

[0002] The application of thermal automation technology in coal mine production processes is becoming increasingly widespread. In the vertical conveying of coal materials, the bucket elevator, as a key thermal automation feeding device, directly affects the stable operation of the entire production system. The equipment transports coal to the bottom hopper of the bucket elevator, and through the surface-circulating feeding buckets, the coal can be transported to a higher position for feeding.

[0003] During operation, coal conveying is guided to the bottom hopper of the bucket elevator by an external conveying mechanism, and then the bucket is automatically loaded with coal. During the lifting process, the equipment is subjected to vibration and impact, which can easily cause some materials (especially coal powder) to be shaken off and spilled. This not only causes material waste and material accumulation at the bottom of the machine, but also seriously deteriorates the underground environment due to secondary dust. Furthermore, it requires operators to clean up the accumulated material at the bottom after the conveying stops.

[0004] Therefore, how to solve the above-mentioned technical problems has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0015] Optionally, the dust scraping component further includes a tapping assembly, which includes a series plate fixedly connected to the scraper, a groove formed in the inner wall of the cover plate, and a tapping plate slidably connected to the groove.

[0022] like Figure 1-8 As shown, a thermal automation production feeding device includes: an elevator 10 and a feeding hopper 11 fixedly connected to the surface of its conveyor belt. It also includes: The covering component includes several cover plates 12 that are slidably connected to both sides of the elevator 10 and can move synchronously with the feed hopper 11, for covering the top of the feed hopper 11 during the lifting process.

[0023] In some embodiments, the covering component further includes a guide assembly 14, which is disposed between the covering plate 12 and the elevator 10, for guiding the covering plate 12 to move along a predetermined path.

[0024] The guide assembly 14 includes guide grooves 141 formed on both sides of the hoist 10, and a slider 142 slidably connected to the guide grooves 141 and rotatably connected to the cover plate 12 via a connecting block 143.

[0025] In some embodiments, a switching component is also included, comprising a drive assembly 21 disposed between the guide assembly 14 and the rotating shaft 20, the rotating shaft 20 being fixedly connected to the cover plate 12. When the feed hopper 11 moves the cover plate 12 to the unloading station, the drive assembly 21 drives the cover plate 12 to rotate, switching it from a covered state to an inclined guiding state.

[0026] In some embodiments, the drive assembly 21 includes a gear 211 fixedly connected to the connecting block 143 and toothed plates 212 fixedly connected to both sides of the hoist 10, the meshing grooves of the toothed plates 212 being adapted to the gear 211. The drive assembly 21 also includes a torsion spring 213 sleeved on the rotating shaft 20, the two ends of the torsion spring 213 being fixedly connected to the connecting block 143.

[0027] In some embodiments, the switching component further includes a limiting assembly 22, which includes: limiting blocks 221 slidably connected to both sides of the elevator 10, a guide rod 222 fixed to the elevator 10, the limiting blocks 221 being slidably connected to the guide rod 222, and a first spring 223 sleeved on the guide rod 222 for providing a restoring elastic force to the limiting blocks 221. The limiting blocks 221 are used to temporarily support the slider 142 at the unloading station to maintain the guiding state of the cover plate 12.

[0028] In some embodiments, the switching component further includes a steering assembly 23, which includes a rectangular groove 231 formed inside the guide groove 141 and a guide plate 232 fixedly connected to the surface of the elevator 10. The rectangular groove 231 and the guide plate 232 work together to guide the cover plate 12, after unloading, to rotate and return to its initial position.

[0029] In some embodiments, a slide plate 13 is slidably connected to the inner wall of the cover plate 12. The slide plate 13 slides down when the cover plate 12 is in the material guiding state, and its inclined surface is used to abut against the outer collection frame.

[0030] In some embodiments, the device further includes a dust scraping component, the dust scraping component comprising a scraper 30 slidably connected to the surface of the cover plate 12.

[0031] A power assembly 31 is disposed between the scraper 30 and the elevator 10, and is used to drive the scraper 30 to scrape off the dust accumulated on the surface of the cover plate 12.

[0032] In some embodiments, the power assembly 31 includes a round rod 311 fixed to the elevator 10, a sliding frame 312 slidably connected to the round rod 311, a second spring 313 sleeved on the round rod 311, the second spring 313 being used to reset the sliding frame 312, and a docking rod 314 slidably connected to the sliding frame 312, the docking rod 314 having a limit groove 315 on the side near the feed hopper 11.

[0033] When the feeding hopper 11 moves, it can be engaged in the limiting groove 315 and drive the sliding frame 312 to move, so as to push the scraper 30 to move through the push plate 316 and the rotating plate 317.

[0034] In some embodiments, the dust scraping component further includes a tapping assembly 32, which includes a series plate 321 fixedly connected to the scraper 30, a groove 322 formed in the inner wall of the cover plate 12, and a tapping plate 323 slidably connected to the groove 322.

[0035] When the scraper 30 moves, it drives the striking plate 323 to move within the groove 322 via the connecting plate 321, and periodically strikes the inner wall of the cover plate 12.

[0036] Example 1 Reference Figures 1-4 This is the first embodiment of the present invention. This embodiment provides a thermal automated production feeding device, which achieves the effect of covering the upper side of the feeding hopper 11 to prevent leakage and falling during the upward movement of the feeding hopper 11. It includes a covering component, including a hoist 10. The surface of the conveyor belt of the hoist 10 is fixedly connected to the feeding hopper 11 for conveying coal. Both sides of the hoist 10 are slidably connected to a plurality of covering plates 12 for surface sealing and blocking as the feeding hopper 11 moves. The inner walls of the plurality of covering plates 12 are slidably connected to sliding plates 13. A guide component 14 is provided between the plurality of covering plates 12 and the hoist 10.

[0037] Specifically, when the elevator 10 moves the feeding bucket 11, it can move to the underside of the cover plate 12. Then the feeding bucket 11 abuts against the cover plate 12 and pushes the cover plate 12 to move synchronously. This can prevent the coal blocks inside the feeding bucket 11 from falling to the ground due to the vibration generated by the operation of the elevator 10, and at the same time, the coal ash inside the feeding bucket 11 will not scatter to the outside.

[0038] Furthermore, the guide assembly 14 includes guide grooves 141 formed on both sides of the hoist 10, a slider 142 is slidably connected to the inner wall of the guide groove 141, a connecting block 143 is fixedly connected to the outer surface of the slider 142, and one side of the cover plate 12 is rotatably connected to the connecting block 143.

[0039] The feeding hopper 11 moves, causing the cover plate 12 to move along the guide groove 141, and the slider 142 moves along the guide groove 141. The slider 142 has rounded corners on all four sides. The different structures presented by the guide groove 141 can change the display state of the cover plate 12.

[0040] In normal operation, the slider 142 is located at the bottom of the guide groove 141, and the guide groove 141 limits the slider 142, allowing the slider 142 to work with the connecting block 143 to limit the position of the cover plate 12. When the feeding hopper 11 is filled with coal from the lower hopper of the elevator 10, it will move upward with the conveyor belt on the surface of the elevator 10. Then, the upper side of the feeding hopper 11 will abut against the lower side of the cover plate 12. At this time, the feeding hopper 11 drives the cover plate 12 to move synchronously. The cover plate 12 is located above the feeding hopper 11 and has a covering effect. If there is too much coal inside, it will not fall outside due to the operation of the elevator 10, ensuring the quality of the working environment around the elevator 10 for the operators and thus improving the health of the operators.

[0041] In summary, by moving the feed hopper 11 upwards, the upper side of the feed hopper 11 is shielded during the conveying process, preventing the coal and coal ash inside the feed hopper 11 from leaking out, thereby improving the working environment for operators around the hoist 10.

[0042] Example 2 Reference Figures 1-7This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a switching component for a thermal automated production feeding device, which solves the problem that coal ore conveyed by the feeding hopper 11 will fall downwards into the collection frame. The switching component includes a rotating shaft 20 rotatably connected to one side of the cover plate 12. A drive component 21 is provided between the rotating shaft 20 and the guide component 14. A limit component 22 is provided between the guide component 14 and the elevator 10. A steering component 23 is provided between the guide component 14 and the elevator 10. The drive component 21 includes a gear 211 rotatably connected to the side of the connecting block 143 away from the cover plate 12. The rotating shaft 20 passes through the connecting block 143 and is fixedly connected to the gear 211. Two toothed plates 212 are fixedly connected to both sides of the elevator 10. The meshing grooves on the inner side of the toothed plates 212 are adapted to the meshing teeth of the gear 211. A torsion spring 213 is sleeved on the surface of the rotating shaft 20. Both ends of the torsion spring 213 are fixedly connected to the inner side of the connecting block 143. The limiting assembly 22 includes limiting blocks 221 slidably connected to both sides of the hoist 10. Guide rods 222 are fixedly connected to both sides of the hoist 10. The limiting blocks 221 are slidably connected to the guide rods 222. A first spring 223 is sleeved on the surface of the guide rods 222. The two ends of the first spring 223 are fixedly connected to the hoist 10 and the limiting blocks 221, respectively. The steering assembly 23 includes a rectangular groove 231 formed inside the guide groove 141. A guide plate 232 is fixedly connected to the surface of the hoist 10.

[0043] Specifically, when it moves to the left toothed plate 212 position, it can help the cover plate 12 flip upward, thereby helping the cover plate 12 to be parallel to the side of the elevator 10. At the same time, the cover plate 12 and the side of the elevator 10 abut against each other, and will not be reset by the effect of the torsion spring 213. Further, the slider falls to the upper side of the limit block 221. At this time, the cover plate 12 is in an inclined state, the feed hopper 11 arrives at the side of the collection frame in advance, and the slide plate 13 slides outward. Its inclined surface abuts against the surface of the collection frame, which can guide the coal discharged inside the feed hopper 11 to fall into the collection frame, while preventing the coal from falling to the ground from the gap between the elevator 10 and the collection frame.

[0044] Furthermore, the upper dimension of the guide groove 141 is larger than the dimension of the slider 142, and the upper side of the guide groove 141 is inclined from top to bottom. The upward-facing side of the limiting block 221 is inclined, and the upper gap of the limiting block 221 is larger than the dimension of the slider 142.

[0045] The guide groove 141 can limit the position of the slider 142, so that the slider 142 can only move along the guide groove 141. The structure of the guide groove 141 presents different states at different positions. The upper side of the guide block is inclined and larger than the slider 142, which can help the slider 142 drive the cover plate 12 to the gap position between the elevator 10 and the collection frame in advance. It can guide the coal falling inside when the collection frame is vertical. When the slider 142 moves to the upper side of the limit block 221, it is limited by the limit block 221 and cannot continue to slide down when there is no force, which can support the slider 142. Later, when the feeding hopper 11 abuts against the surface of the cover plate 12, it can provide power to make the slider 142 push the limit block 221 to slide along the guide rod 222 until a gap larger than the size of the slider 142 is released, so that the slider 142 can continue to slide along the guide groove 141.

[0046] In use, the upward movement of the feeding hopper 11 synchronously drives the cover plate 12 to move upward through the guide groove 141. When the gear 211 moves with the connecting block 143 to the position of the toothed plate 212, it can mesh with the toothed plate 212. Furthermore, the effect of the toothed plate 212 can drive the rotating shaft 20 to rotate, causing the rotating shaft 20 to synchronously drive the cover plate 12 to rotate outward. When the gear 211 moves to the tail end of the toothed plate 212, the slider 142 is at the top of the inclined groove on the upper side of the guide groove 141, and at the same time, the cover plate 12 and the side of the elevator 10 are... In a parallel fit, the slider 142 slides down the inclined groove until it reaches the upper gap position of the limiting block 221. At this point, the limiting block 221 supports and limits the slider 142, preventing it from sliding further down. Simultaneously, the cover plate 12 disengages from its abutment against the side of the elevator 10. Under the effect of the torsion spring 213, the cover plate 12 rotates towards the center of the elevator 10 until it reaches a horizontal position. Furthermore, because the cover plate 12 is tilted downwards, the slide plate 13 on the inner wall of the cover plate 12 can slide down, causing its inclined surface to abut against... The external equipment collection frame is located on the side, while the feeding hopper 11 is positioned above it via the elevator 10. When the feeding hopper 11 is in a vertical state, the coal inside the feeding hopper 11 will fall downwards. At this time, the coal can fall onto the surface of the cover plate 12 and the sliding plate 13. Guided by the cover plate 12 and the sliding plate 13, the coal that does not directly roll into the collection frame will be guided by the slope and gradually fall into the collection frame. Then the feeding hopper 11 continues to move. When the feeding hopper 11 moves to the upper side of the cover plate 12, it is in contact with the cover plate 12. At the same time, a pushing force is applied to the cover plate 12, and the slider 142 can press against the upper inclined surface of the limiting block 221, so that the limiting block 221 can slide and retract inward along the guide rod 222. When the limiting block 221 is fully retracted, its front end gap is greater than the size of the slider 142. At this time, the slider 142 will continue to slide down and enter the guide groove 141, and slide down along the guide groove 141. After the slider 142 leaves, the limiting block 221 can be reset by the effect of the first spring 223, and limit the next slider 142 to come to the position.

[0047] Subsequently, gear 211 can further contact gear plate 212. At this time, the meshing groove of gear plate 212 drives gear 211 to rotate outward, which can separate cover plate 12 from feed hopper 11 again. At the same time, cover plate 12 and slider 142 will continue to slide down under gravity. Meanwhile, cover plate 12 is limited by the side of elevator 10 and is in a parallel state of contact with the side of elevator 10. Then, when slider 142 moves to the position of rectangular groove 231, the lower side of cover plate 12 abuts against guide plate 232. At this time, guide plate 232... The surface of 32 forms a guide rail, which can drive the cover plate 12 to tilt and rotate to the left side of the elevator 10. The rectangular groove 231 is larger than the guide groove 141, and the slider 142 can rotate smoothly until the cover plate 12 rotates to the left side of the elevator 10. At the same time, the slider 142 is at the bottom of the guide groove 141, and the cover plate 12 is between the two feed hoppers 11. Then, it is reset by the effect of the torsion spring 213 and can continue to be in a horizontal state, and further cover when the next feed hopper 11 moves up.

[0048] In summary, when the feeding hopper 11 moves the cover plate 12 to different positions, with the assistance of the guide groove 141, the feeding hopper 11 and the cover plate 12 can be separated. Furthermore, the cover plate 12 is tilted and located in the gap between the elevator 10 and the collection frame, which can guide the coal blocks falling from the feeding hopper 11 and prevent the coal blocks from falling, thereby improving the conveying effect of the coal blocks.

[0049] Example 3 Reference Figures 1-8This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a dust scraping component for a thermal automated production feeding device. This solves the problem that coal ash accumulated on the surface of the cover plate 12 after covering and guiding the coal blocks will scatter and pollute the external air during the movement of the cover plate 12. The component includes a dust scraping component comprising a scraper 30 slidably connected to the surface of the cover plate 12. A power assembly 31 is provided between the scraper 30 and the elevator 10, and a striking assembly 32 is provided between the scraper 30 and the cover plate 12. The power assembly 31 includes round rods 311 fixedly connected to both sides of the elevator 10. A sliding frame 312 is slidably connected to the surface of the round rods 311, and a second spring 313 is sleeved on the surface of the round rods 311. The two ends of the second spring 313 are fixedly connected to the elevator 10 and the sliding frame 312, respectively. A connecting rod 314 is slidably connected to the inner wall of the sliding frame 312. A limiting groove 315 is opened on the side of the connecting rod 314 near the feeding hopper 11. A push plate 316 is fixedly connected to the arc surface of the sliding frame 312. A rotating plate 317 is rotatably connected to the side of the push plate 316 away from the sliding frame 312. The side of the rotating plate 317 away from the push plate 316 has a protrusion smaller than the thickness of the rotating plate 317. A connecting groove 318 is opened on the surface of the scraper 30. The side of the connecting groove 318 near the feeding hopper 11 is inclined. The size of the connecting groove 318 is larger than the thickness of the feeding hopper 11. The size of the protrusion of the rotating plate 317 is smaller than the size of the connecting groove 318. A drive groove 319 is opened on the surface of the elevator 10. The drive groove 319 is in the shape of an "L" with the short side inclined. The lower protrusion of the connecting rod 314 is located on the inner wall of the drive groove 319. The striking assembly 32 includes a series plate 321 fixedly connected to the outside of the scraper 30. The inner wall of the cover plate 12 is provided with a groove 322. The groove 322 is in the shape of an "L" with the short side inclined. A striking plate 323 is slidably connected to the inner wall of the groove 322. A roller 324 is rotatably connected to the surface of the striking plate 323. A number of grooves 325 are provided on the inner wall of the groove 322.

[0050] Specifically, when the feeding hopper 11 moves to the appropriate position, it can contact the limiting groove 315 on the surface of the docking rod 314. Then, the feeding hopper 11 can drive the docking rod 314 to move synchronously. The docking rod 314, together with the sliding frame 312, slides down along the round rod 311, so that the push plate 316 drives the protrusion of the rotating plate 317 to be inside the docking groove 318. Then, while the push plate 316 moves with the sliding frame 312, it can push the rotating plate 317 to drive the scraper 30 to slide outward. The scraper 30 will drive the connecting plate 321, and synchronously drive the striking plate 323 inside the chute 322 to strike the cover plate 12 up and down. By scraping dust and striking, the cleaning effect of coal ash on the upper side of the cover plate 12 is increased.

[0051] Furthermore, a through hole is provided on the surface of the elevator 10 at the tail end of the push plate 316, and the size of the through hole is larger than the size of the push plate 316.

[0052] The through hole can limit the push plate 316, and the through hole is larger than the size of the push plate 316, so that the push plate 316 can make self-adaptive adjustment when it drives the rotating plate 317 to push the scraper 30, which prevents the support from being damaged due to the inability of the parts to adjust, thereby improving the service life of the parts.

[0053] In use, when the slider 142 and the cover plate 12 move to the upper inclined surface of the guide groove 141, the cover plate 12 can separate from the feeding hopper 11. As the cover plate 12 is limited by the limiting block 221 and is in the gap between the elevator 10 and the collection frame, the side of the feeding hopper 11 is driven by the elevator 10 to move to the limiting groove 315 position. At this time, the feeding hopper 11 is connected to the docking rod 314. Subsequently, when the feeding hopper 11 moves, it will push the docking rod 314 and the sliding frame 312 to slide down along the round rod 311. At this time, the protrusion of the rotating plate 317 is aligned with the docking groove 318 on the back of the scraper 30, and at the same time, the lower part of the docking rod 314... The side protrusion is located inside the drive groove 319. The connecting rod 314 slides down the drive groove 319 synchronously with the sliding frame 312. As the sliding frame 312 moves down, it pushes the push plate 316 and the rotating plate 317, thereby driving the scraper 30 to slide along the surface of the cover plate 12. Through its inclined surface, it can guide the coal ash on the surface of the cover plate 12 to the direction of the collection frame. When the connecting rod 314 moves to the end of the drive groove 319, since the end is inclined outward, it can guide the connecting rod 314 to slide outward. At this time, in conjunction with the inclined surface of the limiting groove 315, it can help the feeding hopper 11 to disengage from the limiting groove 315 and achieve separation. At this time, the sliding frame 312 will drive the connecting rod 314 to slide outward. 14 is reset by the effect of the second spring 313, facilitating the guidance of the scraper 30 again. Simultaneously, as the scraper 30 slides towards the collection frame, the connecting plate 321 connected to the side of the scraper 30 drives the striking plate 323 to move synchronously, allowing the striking plate 323 to slide out from the inclined short side of the groove 322. This, combined with the roller 324, allows for smooth sliding within the groove 322. When the scraper 30 slides along the surface of the cover plate 12, the striking plate 323 inside the groove 322, guided by the groove 325, repeatedly strikes the inner wall of the cover plate 12, causing it to vibrate and aiding in scraping away debris. The coal ash and the coal ash on the upper side of the slide plate 13 fall into the collection box, thereby improving the cleaning effect of coal ash. Subsequently, when the cover plate 12 is driven away from the position of the limit block 221 by the feed hopper 11, the lower inclined surface of the slide plate 13 can help it slide back to the inner wall of the cover plate 12. Furthermore, when the cover plate 12 is driven to rotate by the toothed plate 212, it achieves complete reset. At the same time, the scraper 30 can also be reset synchronously because the cover plate 12 is vertical. This allows the striking plate 323 to be in the short side inclined position of the slide groove 322. When it is not driven, it will not move to the outside by itself, thereby reducing the long-term collision of parts and reducing their service life.

[0054] In summary, when the cover plate 12 is positioned between the hoist 10 and the external collection frame to guide the falling coal, the coal dust falling from the mine will be guided by the scraper 30 and pushed into the collection frame, preventing it from scattering outside and affecting the working environment, while also improving the utilization rate of the coal mine.

[0055] In this application, 1. By using the provided covering component, the slider 142 can drive the cover plate 12 to move along the guide groove 141. At this time, the cover plate 12 is located on the upper side of the feeding hopper 11 and moves synchronously with the feeding hopper 11, thereby achieving the effect of covering the coal inside the feeding hopper 11, while preventing coal blocks from falling and coal ash from scattering, thus optimizing the working environment.

[0056] 2. By using the switching components, the drive assembly 21, the limit assembly 22, and the steering assembly 23, the cover plate 12 can be positioned in different states at different locations. Then, before the feed hopper 11 discharges material, the cover plate 12 is positioned between the elevator 10 and the collection frame, thus guiding the coal mine to feed. Coal and coal ash will not fall to the ground from the gap between the elevator 10 and the collection frame, eliminating the need for additional cleaning steps by operators.

[0057] 3. By using the dust scraping component, the movement of the feeding hopper 11 drives the power component 31, so that after the feeding hopper 11 finishes feeding, the scraper 30 achieves the effect of cleaning the coal ash on the surface of the cover plate 12, so that the coal ash enters the collection frame and will not fall to the ground during subsequent movement, further ensuring the air quality of the working environment.

[0058] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of this disclosure, and this disclosure is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and substance of this disclosure, and these modifications and improvements are also considered to be within the scope of protection of this disclosure.
