Description

Technical Field

[0001] This invention relates to the field of belt conveyors, and in particular to a dustproof belt conveyor for mining. Background Technology

[0002] In mining and material transfer processes, belt conveyors, as core equipment for continuous transportation, are widely used in underground roadways, open-pit mines, and surface screening and transfer systems. During the transport of bulk materials such as coal and ore, material transfer, impact during material drop, and belt operation easily generate large amounts of dust. This not only causes material loss but also severely deteriorates the underground and on-site working environment, endangering the health of operators. Furthermore, it poses safety hazards such as dust explosions, equipment wear and tear due to dust accumulation, and environmental pollution.

[0003] Existing dust control measures for mine belt conveyors mostly employ traditional methods such as simple dust covers, spray dust suppression, and manual cleaning. These methods generally suffer from poor dust control effectiveness, unreasonable sealing structures, easy dust leakage and re-emergence, and inconvenient maintenance. Traditional dust control devices often use dustproof felt for dust prevention. The dustproof felt is usually fixed inside the dust cover and comes into direct contact with dust, requiring regular cleaning. However, the dust cover has a certain length, and the fixed dustproof felt inside makes cleaning inconvenient. Cleaning equipment needs to reach inside the dust cover for cleaning, which is quite troublesome. Summary of the Invention

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figure 1 As shown in the figure, an embodiment of the present invention provides a dustproof belt conveyor for mining, including a conveying mechanism 100. A feeding mechanism 200 is provided at one end of the conveying mechanism 100. The ore enters the conveying mechanism 100 through the feeding mechanism 200. A winding mechanism 300 is provided at the other end of the conveying mechanism 100. The winding mechanism 300 is used for laying and winding flame-retardant dustproof felt. The winding mechanism 300 is used to lay flame-retardant dustproof felt on the top and side shells inside the conveying mechanism 100. The flame-retardant dustproof felt is laid in a U-shape inside the conveying mechanism 100.

[0020] like Figure 2 As shown, the conveying mechanism 100 includes a bottom support 101, a conveyor belt 102 is mounted on the bottom support 101, and a first dust cover 103 is also mounted on the bottom support 101. The conveyor belt 102 is located inside the first dust cover 103. The feeding mechanism 200 includes a second dust cover 201, and a feeding funnel 202 is fixedly mounted on the second dust cover 201. The first dust cover 103 and the second dust cover 201 are spliced ​​together to form a complete dust cover. When the ore enters the conveyor belt 102 through the feeding funnel 202, the ore will fall under the action of gravity, generating fine dust. During the conveying process, the smaller dust particles will be suspended in the air. At this time, the first dust cover 103 and the second dust cover 201 play a dustproof role, confining the dust inside the dust cover, effectively playing a dustproof role.

[0021] During mining transportation, fine dust from materials is repeatedly stirred up by belt movement, vibration, and airflow disturbance. The smooth, hard surface of metal dust covers makes it easy for dust to adhere, harden, and become difficult to clean. Therefore, flame-retardant dustproof felt is needed inside the dust cover. Laying this felt on the inner wall of the conveyor belt sealing cover serves two purposes: firstly, it absorbs fine dust generated during transport, suppresses secondary dust generation, and prevents dust from directly adhering to and hardening on the inner wall of the metal cover, facilitating later cleaning and maintenance; secondly, the flame-retardant dustproof felt possesses flame-retardant and anti-static properties, eliminating static electricity buildup and reducing the risk of sparks, meeting the safety requirements of flammable and explosive dust environments in underground mines. It also buffers airflow, reduces noise, protects the sealing cover itself, and extends the equipment's service life.

[0022] Flame-retardant dustproof felt is usually pre-laid inside the dust cover and is fixedly bonded to the dust cover. Since the flame-retardant dustproof felt comes into direct contact with dust during use, it needs to be cleaned regularly. Because the dust cover has a certain length, the fixed bonding of the flame-retardant dustproof felt inside the dust cover makes it inconvenient to clean. Cleaning equipment needs to be inserted into the inside of the dust cover for cleaning, which is quite troublesome.

[0023] Therefore, this embodiment proposes a rollable flame-retardant dustproof felt, which is laid on the top and sides of the inside of the dust cover. When too many impurities accumulate on the flame-retardant dustproof felt, the flame-retardant dustproof felt laid inside the dust cover can be rolled up to the outside of the equipment. During the rolling process, it can be cleaned with cleaning equipment. When the flame-retardant dustproof felt is used to its limit, it can also be replaced and re-laid.

[0024] like Figure 2 and Figure 3 As shown, the rollable flame-retardant dustproof felt includes a top laying mechanism and two sets of side laying mechanisms. The top laying mechanism includes a first take-up roller 306, and the side laying mechanism includes second take-up rollers 303 located at both ends of the first take-up roller 306, as shown. Figure 4 As shown, a first flame-retardant dustproof felt 307 is wound onto the first take-up roller 306 and is laid on the top inner surface of the first dust cover 103. A second flame-retardant dustproof felt 308 is wound onto the second take-up roller 303 and is laid on both sides of the inner surface of the first dust cover 103. Figure 5 As shown, the first dust cover 103 has a sliding groove 329 inside, and a clamping assembly is slidably mounted on the sliding groove 329. The clamping assembly includes a horizontal clamping plate 327 and two vertical clamping plates 328. The two vertical clamping plates 328 are located at both ends of the horizontal clamping plate 327 and are fixedly connected to it. The horizontal clamping plate 327 is slidably engaged with the top sliding groove 329 inside the first dust cover 103, and the two vertical clamping plates 328 are slidably engaged with the side sliding grooves 329 inside the first dust cover 103. The horizontal clamping plate 327 is used to clamp the initial end of the first flame-retardant dustproof felt 307, and the two vertical clamping plates 328 are used to clamp the initial end of the first flame-retardant dustproof felt 307. 8 are used to clamp the initial ends of the two second flame-retardant dustproof felts 308 respectively. When in use, the clamping components can be moved laterally to pull a set of first flame-retardant dustproof felts 307 and second flame-retardant dustproof felts 308 laterally and lay them inside the first dust cover 103. In this embodiment, the clamping components are U-shaped structures. When clamping the initial ends of the first flame-retardant dustproof felts 307 and second flame-retardant dustproof felts 308, it is necessary to ensure that there is almost no gap at the splice between the two sets of second flame-retardant dustproof felts 308 and the first flame-retardant dustproof felts 307, so as to avoid large gaps at the splice, which can easily cause dust accumulation.

[0025] like Figure 5As shown, this embodiment provides a method for moving a clamping component. However, in implementing this technical solution, other conventional technical means known to those skilled in the art are also included. Specifically, the top of the inner part of the first dust cover 103 is provided with a threaded groove, and a first threaded rod 326 is rotatably provided in the threaded groove. The first threaded rod 326 is threadedly engaged with the transverse clamping plate 327 of the clamping component. The first threaded rod 326 is driven by a first motor 325. In use, when the first motor 325 drives the first threaded rod 326 to rotate, the transverse clamping plate 327 can be moved laterally, which further realizes the transverse movement of the clamping component. The transverse movement of the clamping component realizes the pulling of the initial ends of the first flame-retardant dustproof felt 307 and the second flame-retardant dustproof felt 308, thereby realizing the laying of the flame-retardant dustproof felt.

[0026] like Figure 2 As shown, in this embodiment, both the first take-up roller 306 and the second take-up roller 303 can be detachably installed on the take-up mechanism 300. After installation, they can rotate on the take-up mechanism 300 to achieve the take-up function. Specifically, the structures of the second take-up rollers 303 on both sides are the same. Taking one of the second take-up rollers 303 as an example, the take-up mechanism 300 also includes a first fixed seat 301, which is fixedly connected to the first dust cover 103. A first mounting seat 302 is rotatably provided on the first fixed seat 301. The device is equipped with a first connecting member 309, and a coil spring is provided between the first connecting member 309 and the first mounting base 302. A second take-up roller 303 is detachably connected to the first connecting member 309. When the clamping assembly drives the initial end of the second flame-retardant dustproof felt 308 to move laterally for laying, the coil spring between the first connecting member 309 and the first mounting base 302 will be pulled. When the clamping assembly drives the second flame-retardant dustproof felt 308 to move back, the coil spring begins to recover its deformation, causing the second take-up roller 303 to rotate in the opposite direction, thereby achieving the take-up of the second flame-retardant dustproof felt 308.

[0027] like Figure 2 As shown, for the first take-up roller 306 at the inner top of the first dust cover 103, the take-up mechanism 300 also includes second fixed seats 304 fixed on both sides of the top of the first dust cover 103. Second connecting pieces 305 are rotatably provided on both sides of the second fixed seats 304. A coil spring is also provided between the second fixed seats 304 and the second connecting pieces 305. The first take-up roller 306 is installed between the two second connecting pieces 305. When the clamping assembly drives the initial end of the first flame-retardant dustproof felt 307 to move laterally for laying, the coil spring between the second fixed seats 304 and the second connecting pieces 305 will be pulled. When the clamping assembly drives the first flame-retardant dustproof felt 307 to move back, the coil spring begins to recover its deformation, causing the first take-up roller 306 to rotate in the opposite direction, thereby achieving the take-up of the first flame-retardant dustproof felt 307. The first flame-retardant dustproof felt 307 and the second flame-retardant dustproof felt 308 can be synchronously taken up under the action of the clamping assembly and the coil spring.

[0028] In this embodiment, the second take-up rollers 303 on both sides are vertically mounted on the first connector 309. They can be directly inserted into the mating holes on the first connector 309 for installation. During operation, the second take-up rollers 303 rotate on their own to take up and unwind the second flame-retardant dustproof felt 308. However, since the first take-up roller 306 is arranged horizontally, if it is directly inserted horizontally between the second connectors 305, it may fall off due to its own gravity when the first take-up roller 306 rotates to rewind. Therefore, it is necessary to limit the first take-up roller 306 between the second connectors 305. Thus, the second connector 305 in this embodiment also includes a limiting component for the first take-up roller 306.

[0029] like Figure 6 As shown, the second connector 305 includes a connecting plate 30501, a first mounting plate 30502 fixedly mounted on the connecting plate 30501, and a second mounting plate 30503 fixedly mounted on the first mounting plate 30502. The second mounting plate 30503 has an L-shaped structure, and the first mounting plate 30502 and the second mounting plate 30503 form a U-shaped area. Both ends of the first take-up roller 306 are fixedly provided with connecting ends 330. In use, the connecting ends 330 at both ends of the first take-up roller 306 can be placed directly in the U-shaped area formed by the first mounting plate 30502 and the second mounting plate 30503, and then limited by the limiting component.

[0030] like Figure 6 and Figure 7 As shown, the limiting component includes a limiting rod 30506, with an insertion hole 30507 inside the limiting rod 30506. A protruding end 30508 is fixedly provided at the bottom of the limiting rod 30506, and a recessed area 30509 is provided between the protruding end 30508 and the limiting rod 30506. An extension rod 30510 is provided at the bottom of the protruding end 30508, and a first mating plate 30511 is fixedly provided at the bottom of the extension rod 30510. Rotating buckles 30512 are rotatably provided on both sides of the extension rod 30510. A first spring 30513 is provided between the rotating buckles 30512 on both sides and the protruding end 30508. When the two rotating buckles 30512 are pinched, the first spring 30513 may be compressed. At this time, the distance between the two rotating buckles 30512 becomes smaller, and the rotating buckles 30512 move and hide into the recessed area 30509.

[0031] like Figure 6As shown, the second mounting plate 30503 and the first mounting plate 30502 are respectively provided with a first limiting hole 30504 and a second limiting hole 30505, wherein the diameter of the first limiting hole 30504 is larger than that of the second limiting hole 30505, and the connecting end 330 is provided with a third limiting hole (not marked in the figure). In use, the limiting component is directly inserted into the first limiting hole 30504, the third limiting hole and the second limiting hole 30505 to limit the first winding roller 306. In this embodiment, the size of the first mating plate 30511 is smaller than the size of the first limiting hole 30504, the third limiting hole and the second limiting hole 30505, which facilitates the insertion of the limiting component.

[0032] The insertion of the limiting component in this embodiment is relatively convenient. It can be inserted directly along the first limiting hole 30504, the third limiting hole, and the second limiting hole 30505. However, when the first winding roller 306 needs to be removed, the limiting component needs to be removed in advance. The removal methods include directly pinching the rotating buckle 30512 and manually removing the limiting component. However, manual removal is more troublesome, and the removed limiting component is in an independent state and needs to be properly placed or carried, which is inconvenient. Therefore, this embodiment also proposes a limiting component removal mechanism to assist in the removal of the limiting component.

[0033] Figure 8 and Figure 9 As shown, a base plate 30517 is also fixedly provided at the bottom of the connecting plate 30501. A third spring 30518 is fixedly provided on the base plate 30517. A second mating plate 30519 is fixedly provided at the top of the third spring 30518. When the limiting component moves downward, the first mating plate 30511 on it will gradually contact the second mating plate 30519 and compress the third spring 30518. When the limiting component reaches below the second limiting hole 30505, the two rotating buckles 30512 open to achieve the limiting.

[0034] like Figure 6As shown, the limiting component removal mechanism includes two pressure plates 30515 slidably disposed on both sides of the two rotating buckles 30512. A moving groove 30514 is provided on the side of the first mounting plate 30502. The two pressure plates 30515 are slidably disposed within the moving groove 30514. A second spring 30516 is fixedly connected between the two pressure plates 30515. When the limiting component needs to be removed, the two pressure plates 30515 are directly pinched together, and the pressure plates 30515 press against the two rotating buckles 30512 respectively. At this time, the two rotating buckles 30512... 2. With the reduced spacing, the plate 30515 can pass through the first limiting hole 30504, the third limiting hole, and the second limiting hole 30505. After releasing, the pressure plate 30515 returns to its initial position under the action of the second spring 30516, and the third spring 30518 begins to recover its deformation, starting to push the limiting component upwards, making it easier to remove the limiting component. In this embodiment, after the third spring 30518 recovers its deformation, the highest position of the second mating plate 30519 is not higher than the first mounting plate 30502, avoiding any impact on the winding and unwinding of the first take-up roller 306. In this embodiment, the rotating buckle 30512 on the limiting component is relatively smooth, preventing the limiting component from being unable to separate due to excessive frictional resistance during removal.

[0035] like Figure 2 As shown, a third mounting plate 315 is fixedly provided on the top of the first dust cover 103. A moving rod 318 is slidably provided on the third mounting plate 315. A connecting rod 319 is fixedly provided at both ends of the moving rod 318. An insert rod 321 is fixedly provided at the bottom of the connecting rod 319. An electromagnet 320 is also fixedly provided at the connection between the insert rod 321 and the connecting rod 319. This embodiment provides a sliding method for the moving rod 318. However, when implementing this technical solution, other conventional technical means known to those skilled in the art are also included. Specifically, a second threaded rod 317 is rotatably provided on the third mounting plate 315, and several sliding rods 316 are fixedly provided. The moving rod 318 is threadedly engaged with the second threaded rod 317 and slidably engaged with the several sliding rods 316. The second threaded rod 317 is driven by a second motor.

[0036] like Figure 2As shown, the bottom ends of the two connecting rods 319 are also fixed with vertical rods 322. The first dust cover 103 is provided with a through groove 324. The vertical rod 322 is slidably engaged with the through groove 324. The end of the vertical rod 322 is fixed with a cylindrical pressure rod 323. The first dust cover 103 is provided with an arc-shaped groove (not shown in the figure). A waist-shaped rod 311 is slidably mounted on the arc-shaped groove. The side of the first dust cover 103 is also fixed with a fourth mounting plate 313. A fourth spring 314 is connected between the fourth mounting plate 313 and the waist-shaped rod 311. The first fixed seat 301 and the first mounting seat 302 are rotatably connected by a rotating shaft. The rotating shaft is fixedly connected to the first mounting seat 302. The end of the rotating shaft is coaxial and fixed with a first gear 310. One end of the waist-shaped rod 311 is fixed with a second gear 312. The first gear 310 and the second gear 312 mesh and drive each other. Figure 10 As shown, when the waist-shaped rod 311 moves along the arc-shaped groove, the second gear 312 on the waist-shaped rod 311 will rotate around the center of the second gear 312. During the rotation process, it meshes with the first gear 310 to drive the rotation, and finally realizes the rotation of the first mounting base 302. At this time, the second take-up roller 303 on the first mounting base 302 rotates outward synchronously, which makes it easy to remove or replace the second flame-retardant dustproof felt 308 on the second take-up roller 303.

[0037] like Figure 10 As shown, in the initial state, as Figure 10 As shown in part a, the limiting component engages with the insert rod 321 via its insertion hole 30507, fixing it onto the insert rod 321. At this point, the placement of the first take-up roller 306 allows for the replacement or removal of the first flame-retardant dustproof felt 307. Subsequently, the insert rod 321 is lowered, inserting the limiting component to the designated position to limit the first take-up roller 306. Figure 10 As shown in Figure b, the vertical rod 322 descends synchronously with the insertion rod 321. The cylindrical pressure rod 323 on the vertical rod 322 gradually contacts the waist-shaped rod 311 and presses it downward. The waist-shaped rod 311 rotates, and the second gear 312 on it meshes with the first gear 310 to achieve the rotation and release of the second take-up roller 303. At this time, the second flame-retardant dustproof felt 308 on the second take-up roller 303 can be removed or replaced. After the first flame-retardant dustproof felt 307 and the second flame-retardant dustproof felt 308 have been removed or replaced, the insertion rod 321 is controlled to rise. The limiting component has achieved the limiting lock and will not rise with the insertion rod 321. The cylindrical pressure rod 323 rises synchronously, and the waist-shaped rod 311 returns to the initial position under the action of the fourth spring 314, and drives the second take-up roller 303 to reset. With the movement of the clamping component, the first flame-retardant dustproof felt 307 and the second flame-retardant dustproof felt 308 are laid.

[0038] When the limiting component needs to be removed, the insertion rod 321 should be lowered to a position above the limiting component. At this time, the insertion rod 321 is not in contact with the limiting component, and the cylindrical pressure rod 323 is not in contact with the waist-shaped rod 311. At this time, the two pressure plates 30515 are pinched together, and the pressure plates 30515 squeeze the two rotating buckles 30512 respectively. The distance between the two rotating buckles 30512 becomes smaller, and they can pass through the first limiting hole 30504, the third limiting hole and the second limiting hole 30505. The third spring 30518 begins to recover its deformation and begins to push the limiting component upward, so that the insertion rod 321 engages with the insertion hole 30507 on the limiting component. At this time, under the attraction of the electromagnet 320, the limiting component moves upward better until the limiting rod 30506 is attached to the electromagnet 320 and adsorbs. The top of the limiting rod 30506 is provided with a ferromagnetic material, which can attract the limiting rods 30506 to each other, and finally the limiting component can be removed and stored.

[0039] Both sides are rotatably provided. In the description of this invention, it should be understood that the terms "upper," "lower," "left," and "right," etc., indicating orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, not indicating or implying that the device or element referred to must have a specific orientation, or a specific orientational structure and operation. Therefore, they should not be construed as limitations on the invention.
