Abstract
Description
Technical Field
[0001] This invention relates to the field of coal crushing and processing technology, specifically providing a mobile conveyor belt coal cleaning device. Background Technology
[0002] In the field of bulk material transportation using belt conveyors, especially in the long-distance transfer of highly viscous and fragile materials such as coal and ore, large pieces of material frequently fall off the edge of the belt due to their own weight and belt vibration and accumulate under the frame, forming a difficult-to-resolve problem of loose coal.
[0003] Traditional solutions attempt to reduce material spillage by adding devices such as coal baffles and scrapers, but they cannot solve the problem of secondary processing of large coal pieces that have already fallen off. On the one hand, if the large coal pieces are not crushed and are directly manually backfilled into the running conveyor belt, they will repeatedly fall off in the undulating sections of the conveyor belt, the turning points of the drums, and the vibrating screening stage due to their excessive size, sharp edges, or poor surface adhesion, forming a vicious cycle of "falling off-backfilling-falling off again", which seriously reduces transportation efficiency and aggravates equipment wear.
[0004] On the other hand, fixed crushing plants require interrupting belt operation and centrally transferring large pieces of coal for processing, resulting in downtime losses and secondary pollution. Mobile crushing equipment is difficult to put into practical use due to problems such as inability to coordinate with belt conveyor cleaning operations, poor compatibility between crushing particle size and belt load (e.g., excessive powdering of hammer crusher output or uneven particle size of jaw crusher) and clogging of rotor by sticky and wet materials.
[0005] More importantly, crushing equipment is often separate from the cleaning system, which causes large pieces of coal to continue to spill during collection and transportation, and the crushed material cannot be seamlessly returned to the conveyor belt due to the lack of a precise backfilling mechanism.
[0006] There is an urgent need in this field for an innovative solution that can move and operate under a belt conveyor, crush large pieces of floating coal in real time, accurately control the output particle size, and achieve automatic closed-loop backfilling of crushed coal, so as to fundamentally solve the problem of large pieces of coal falling back down. Summary of the Invention

[0016] The embodiments of the present invention have the following advantages.
[0017] The first and second mobile platforms are connected by a connecting frame, allowing them to move simultaneously. The first and second mobile platforms reciprocate within the area below the conveyor belt. During the movement of the first mobile platform, the reciprocating gripping mechanism of the coal picking mechanism continuously operates. Coal blocks enter the gripping area of the reciprocating gripping mechanism, which picks up the coal blocks and pushes them towards the feed inlet of the first feeding mechanism. The first feeding mechanism extracts the coal blocks into the second feeding mechanism, and after passing through the second feeding mechanism, they enter the coal crushing mechanism installed on the second mobile platform. The coal crushing mechanism crushes the coal blocks, and then the second feeding mechanism lifts the crushed coal blocks and places them back onto the conveyor belt surface. The coal crushing mechanism then crushes any large, easily detached coal blocks, preventing them from falling off again when repeatedly placed on the conveyor belt surface.
[0018] It has enabled automated and continuous cleaning, crushing and backfilling of loose coal blocks (especially large coal blocks that are prone to repeated falling off) under the belt conveyor, which has significantly improved cleaning efficiency, ensured the continuous and stable operation of the belt conveyor system, and effectively reduced the safety risks and labor intensity of manual cleaning.
[0019] By coordinating the reciprocating gripping mechanism and the first feeding mechanism on the first mobile platform, loose coal can be directly grabbed and lifted on the ground, replacing the traditional inefficient and dangerous manual sweeping or simple mechanical collection.
[0020] Secondly, a coal crushing mechanism is integrated into the synchronously moving second moving platform, which can instantly crush the collected large coal pieces into particles suitable for conveying, thus improving the persistent problem of large coal pieces repeatedly falling off the conveyor belt due to their size or poor adhesion, causing repeated accumulation and cleaning.
[0021] Finally, the crushed coal is directly backfilled onto the upper part of the running conveyor belt through the second feeding mechanism, forming a closed-loop automated process of "collection-crushing-return". This not only shortens the cleaning cycle and avoids belt downtime caused by cleaning, but also reduces secondary spillage and dust pollution during material transfer. At the same time, the entire device can move flexibly along the conveyor belt, covering a wide range and with stronger adaptability, thus comprehensively achieving safe, efficient and low-consumption treatment of floating coal.

[0050] To make the objectives, solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Unless otherwise stated, the terms used herein have their ordinary meanings in the art. The same reference numerals in the drawings represent the same parts.
[0051] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0052] As described above, in the traditional process of cleaning loose coal under a conveyor belt, manual cleaning is required, and coal chunks often fall off the conveyor belt, posing a health hazard to personnel. Furthermore, large coal chunks that fall off and are repeatedly loaded onto the conveyor belt often result in repeated falls.
[0053] To at least partially solve one or more of the above-mentioned problems and other potential problems, an exemplary embodiment of the present invention provides a mobile conveyor belt coal cleaning device, which includes: a first mobile platform 100 and a second mobile platform 200 mounted on one side of the first mobile platform 100 via a connecting frame 300; it also includes: a coal picking mechanism 400 disposed on the first mobile platform 100 and a coal crushing mechanism 500 disposed on the second mobile platform 200; wherein: the coal picking mechanism 400 includes a reciprocating clamping mechanism 410 disposed near the ground, and a first feeding mechanism 420 whose inlet end is disposed within the clamping area of the reciprocating clamping mechanism 410, and the output end of the first feeding mechanism 420 is disposed near the inlet of the coal crushing mechanism 500; a second feeding mechanism 600 is disposed between the first mobile platform 100 and the second mobile platform 200, and a third feeding mechanism 700 is disposed at the output end of the coal crushing mechanism 500, the output end of the third feeding mechanism 700 being disposed facing the upper part of the conveyor belt.
[0054] In the above embodiment, the first mobile platform 100 and the second mobile platform 200 are connected by a connecting frame 300, allowing the first mobile platform 100 and the second mobile platform 200 to move simultaneously. The first mobile platform 100 and the second mobile platform 200 reciprocate in the area below the conveyor belt. During the movement of the first mobile platform 100, the reciprocating clamping mechanism 410 of the coal picking mechanism 400 continuously operates. Coal blocks enter the holding area of the reciprocating clamping mechanism 410, which clamps the coal blocks and pushes them towards the first mobile platform 100. At the inlet of the first feeding mechanism 420, the first feeding mechanism 420 extracts the coal block into the second feeding mechanism 600. After passing through the second feeding mechanism 600, the coal block enters the coal block crushing mechanism 500 installed on the second moving platform 200. The coal block is crushed by the coal block crushing mechanism 500. Then, the crushed coal block is lifted up and placed back on the surface of the conveyor belt by the third feeding mechanism 700. Then, the coal block crushing mechanism 500 crushes the large coal blocks that are easy to fall off, and they fall off again when they are repeatedly placed on the surface of the conveyor belt.
[0055] It has enabled automated and continuous cleaning, crushing and backfilling of loose coal blocks (especially large coal blocks that are prone to repeated falling off) under the belt conveyor, which has significantly improved cleaning efficiency, ensured the continuous and stable operation of the belt conveyor system, and effectively reduced the safety risks and labor intensity of manual cleaning.
[0056] The reciprocating gripping mechanism 410 on the first mobile platform 100 works in conjunction with the first feeding mechanism 420 to directly grab and lift loose coal on the ground, replacing the traditional inefficient and dangerous manual sweeping or simple mechanical collection.
[0057] Secondly, a coal crushing mechanism 500 is integrated on the synchronously moving second moving platform 200, which can instantly crush the collected large coal pieces into particle sizes suitable for conveying, thus improving the persistent problem of large coal pieces repeatedly falling off the conveyor belt due to their size or poor adhesion, causing repeated accumulation and cleaning.
[0058] Finally, the crushed coal is directly backfilled onto the upper part of the running conveyor belt through the third feeding mechanism 700, forming a closed-loop automated process of "collection-crushing-return". This not only shortens the cleaning cycle and avoids belt downtime caused by cleaning, but also reduces secondary spillage and dust pollution during material transfer. At the same time, the entire device can move flexibly along the conveyor belt, covering a wide range and with stronger adaptability, thus comprehensively realizing safe, efficient and low-consumption treatment of floating coal.
[0059] Please see Figures 1-6 In some embodiments, the first mobile platform 100 includes: a first base plate 110 disposed on one side of the second mobile platform 200; and a plurality of casters 120 evenly distributed on the bottom surface of the first base plate 110; a first housing 130 covering the upper part of the first base plate 110, and a first feeding mechanism 420 disposed inside the first housing 130; the second mobile platform 200 includes: a second base plate 210 disposed on one side of the first base plate 110; a track wheel mechanism 220 installed on the bottom surface of the second base plate 210; a second housing 230 covering the upper part of the second base plate 210, and a coal crushing mechanism 500 installed inside the second housing 230.
[0060] In the above embodiment, the first base plate 110 and the second base plate 210 are used to provide an installation platform for the first feeding mechanism 420 and the coal crushing mechanism 500. The first housing 130 and the second housing 230 are covered outside the first feeding mechanism 420 and the coal crushing mechanism 500. When the second moving platform 200 turns, the two sets of tracks of the track wheel mechanism 220 adjust the rotation direction. When the second moving platform 200 turns, the first moving platform 100 is driven to rotate around the second moving platform 200 through the connecting frame 300. When the first moving platform 100 rotates, each universal wheel 120 rotates in the direction of rotation on the bottom surface of the first base plate 110, thereby achieving the purpose of the first moving platform 100 and the second moving platform 200 turning at the same time. The track wheel mechanism 220 installed under the second moving platform 200 drives the first base plate 110 and the second base plate 210 to move continuously in the field under the belt conveyor at the same time.
[0061] Please see Figures 1-6In some embodiments, the reciprocating gripping mechanism 410 includes: a first motor 411, mounted on the inner wall of the first housing 130; and a crank mechanism 412, connected to the drive shaft of the first motor 411 by a belt, with both ends of the crank mechanism 412 rotatably connected to the inner wall of the first housing 130, and the middle section of the crank mechanism 412 being U-shaped; a first drive rod 413, one end of which is hinged to the U-shaped section of the crank mechanism 412; L-shaped grippers 414, symmetrically arranged on both sides of the first drive rod 413 along the axis of the first drive rod 413; and a sleeve 415, sleeved on the first... The drive rod 413 is located near the outer wall of the L-shaped gripper 414; the first connecting rod 416 is hinged at one end to the outer wall of the sleeve 415 and at the other end to one end of the L-shaped gripper 414; the vertical rod 417 is connected in the middle to the end wall of the first drive rod 413 near the L-shaped gripper 414, and the axis of the vertical rod 417 is perpendicular to the axis of the first drive rod 413; the second connecting rod 418 is hinged at one end to the vertical rod 417 and at the other end to the corner of the L-shaped gripper 414; wherein the sleeve 415 is installed inside the first housing 130.
[0062] In the above embodiment, when the reciprocating gripper mechanism is working, the output shaft of the first motor 411 rotates, driving one end of the crank mechanism 412 to rotate via a belt. This causes the crank mechanism 412 to rotate inside the first housing 130. When the U-shaped section of the first drive rod 413 rotates, it drives the first drive rod 413 to reciprocate within the sleeve 415. When the first drive rod 413 reciprocates, it drives the vertical rod 417 and the second connecting rod 418 to move closer to the sleeve 415. At this time, the U-shaped section of the crank mechanism 412 swings to its lowest point, pulling the end of the first drive rod 413 near the crank mechanism 412 downwards. The other end of the first drive rod 413... The lifting of the end causes the first drive rod 413 to lift the L-shaped gripper 414 upwards. At the same time, when the vertical rod 417 moves closer to the sleeve 415, the second connecting rod 418 drives the corner of the L-shaped gripper 414 to move towards the center, thereby achieving the purpose of gripping the coal block. Then, the coal block can be lifted and placed in the feed inlet of the first feeding mechanism 420. It is worth noting that the two sides of the sleeve 415 are hinged to the inner wall of the first box 130, so that the sleeve 415 rotates along its own length, thereby driving the L-shaped gripper 414 to swing around the length of the sleeve 415, thus achieving the effect of lifting the gripped coal block.
[0063] Please see Figures 1-6In some embodiments, the first feeding mechanism 420 includes: a first spiral feeding roller 421, vertically disposed between two L-shaped grippers 414; a first sleeve 422, covering the circumferential outer wall of the first spiral feeding roller 421; wherein: the lower end of the first spiral feeding roller 421 extends out of the bottom end wall of the first sleeve 422; a second motor 423, mounted on the first housing 130, the output shaft of the first motor 411 being drivenly connected to the top end of the first spiral feeding roller 421; a bucket 424 is also provided on the side of the first housing 130 near the L-shaped grippers 414, the surface of the bucket 424 is provided with a coal storage trough 425, and the bottom end of the first spiral feeding roller 421 is disposed in the coal storage trough 425.
[0064] In the above embodiment, the first feeding mechanism 420 works continuously while the reciprocating gripper mechanism is working. When the first feeding mechanism 420 is working, the output shaft of the second motor 423 rotates and drives the first spiral feeding roller 421 to rotate continuously inside the first sleeve 422 through the gear set. The bottom end of the first spiral feeding roller 421 rotates inside the coal storage trough 425. The bucket 424 scoops up coal blocks on its surface as it moves with the first bottom plate 110. The L-shaped gripper 414 clamps the coal blocks and places them at the bottom end of the first spiral feeding roller 421. The first spiral feeding roller 421 transfers the coal blocks to the top end of the first spiral feeding roller 421 through continuous rotation. The coal storage trough 425 is used to store small coal blocks that cannot be lifted along the first spiral feeding roller 421.
[0065] Please see Figures 1-6 In some embodiments, the top surface of the first housing 130 is also provided with a material guide channel 426; one end of the material guide channel 426 is located near the first spiral feeding roller 421, and the lower part of the other end is provided with a common jaw crusher 427; the common jaw crusher 427 is installed inside the first housing 130; the output end located at the lower part of the common jaw crusher 427 is located at the feed end of the second feeding mechanism 600; wherein: the drive shaft of the common jaw crusher 427 is connected to the output shaft belt of the first motor 411.
[0066] In the above embodiment, when the first spiral feeding roller 421 transports the coal block to the top, the coal block falls into the guide channel 426. After passing through the guide channel 426, it falls into the input end of the upper part of the jaw crusher 427. The jaw crusher 427 performs initial compression and crushing on the coal block. After crushing, the coal block falls from below the jaw crusher 427 into the feed end of the second feeding mechanism 600. The second feeding mechanism 600 lifts and transports the coal block to the coal crushing mechanism 500 in the second housing 230 for secondary crushing. The jaw crusher 427 is driven by the first motor 411.
[0067] Please see Figures 1-6 In some embodiments, the coal crushing mechanism 500 includes: a third motor 510, installed inside the second housing 230;
[0068] Hammer crusher 520 is installed inside the second housing 230, and the third motor 510 is connected to the crushing roller belt of hammer crusher 520.
[0069] The first screen 530 has a U-shaped cross-section and is located near the lower part of the crushing roller of the hammer crusher 520.
[0070] The second screen 540 is located below the first screen 530;
[0071] An eccentric rod 550 is installed on the edge of the second screen 540, and the end of the eccentric rod 550 away from the second screen 540 is connected to the output shaft belt of the third motor 510.
[0072] The horizontal conveying mechanism 560 is located below the second screen 540. The upper part of the horizontal conveying mechanism 560 is open, and the working part of the horizontal conveying mechanism 560 is connected to the output shaft belt of the third motor 510.
[0073] In the above embodiment, when the output shaft of the third motor 510 rotates, it drives the crushing roller of the hammer crusher 520 to rotate via a belt. The output end of the second feeding mechanism 600 is located above the hammer crusher 520. When the crushing roller rotates, it strikes the coal blocks discharged by the second feeding mechanism 600, achieving a secondary crushing effect. The crushed coal blocks fall into the second screen 540 after passing through the first screen 530. If the size of the coal blocks does not allow them to pass through the first screen 530 into the second screen 540, the large-sized coal blocks above the first screen 530 are continuously struck and crushed by the crushing roller until the coal blocks can pass through the first screen 530 into the second screen 540. Within 0, the eccentric rod 550 on one side of the second screen 540 is driven by the output shaft of the third motor 510 and works continuously. When the eccentric rod 550 swings, it causes the second screen 540 to vibrate continuously, preventing coal blocks from clogging the holes of the second screen 540. Furthermore, the end of the second screen 540 near the third feeding mechanism 700 is tilted downwards. Large pieces of coal falling on the surface of the second screen 540 are continuously vibrated by the second screen 540, allowing them to smoothly enter the feed inlet at the bottom of the third feeding mechanism 700. The third feeding mechanism 700 lifts these coal pieces and discharges them onto the belt conveyor from the discharge outlet at the top of the third feeding mechanism 700.
[0074] After passing through the second screen 540, the pulverized coal falls into the horizontal conveying mechanism 560. The horizontal conveying mechanism 560 transports the fallen coal pieces to the input end of the third feeding mechanism 700. After being fed by the third feeding mechanism 700, the coal is discharged onto the conveyor belt.
[0075] Please see Figures 1-6In some embodiments, the horizontal conveying mechanism 560 includes: a second spiral feeding roller 561, which is horizontally arranged along the length of the second screen 540; a plurality of deflectors 563, which are respectively arranged between the spiral blades 562 of the second spiral feeding roller 561; and a receiving plate 564, which is arranged on the lower outer wall of the second spiral feeding roller 561; wherein: the second spiral feeding roller 561 is connected to the output shaft belt of the third motor 510; and the end of the receiving plate 564 away from the third motor 510 is arranged close to the input end of the third feeding mechanism 700.
[0076] In the above embodiment, when the output shaft of the third motor 510 rotates, it drives the horizontally arranged second spiral feeding roller 561 to rotate around its own axis via a belt, thereby driving the spiral blades 562 arranged on its circumferential outer wall to rotate. The coal block is pushed from one end of the spiral blade 562 to the other end. When the spiral blade 562 rotates, it drives each deflector plate 563 to rotate around the axis of the second spiral feeding roller 561, thereby continuously pushing the coal block between the spiral blades 562 upward through the deflector plates 563.
[0077] Please see Figures 1-6 In some embodiments, the horizontal conveying mechanism 560 further includes: a first nozzle 565, which is annularly arranged on the upper part of the second spiral feeding roller 561; a water tank 566, which is pipe-connected to the first nozzle 565; and a honeycomb briquette forming mechanism 570, which is arranged at one end of the second spiral feeding roller 561 near the third feeding mechanism 700. The honeycomb briquette forming mechanism 570 includes: a support plate 571, which is arranged on the bottom surface of the second housing 230; an eccentric mechanism 572, which is driven and connected to the third motor 510; a toothed plate 573, which is connected to the working end of the eccentric mechanism 572 and slides vertically back and forth; and multiple perforating rods 574, which are evenly distributed on the bottom surface of the toothed plate 573. The eccentric mechanism 572 cooperates with the third motor 510 to drive the toothed plate 573 to slide vertically back and forth.
[0078] In the above embodiments, when the first nozzle 565, in conjunction with the water tank 566, is used for the horizontal conveying mechanism 560, it continuously sprays water above the second spiral feeding roller 561. After the dust generated by crushing is washed away, the slurry is guided through the receiving plate 564 and finally falls into the support plate 571. The support plate 571 collects the slurry. The surface of the support plate 571 is provided with permeable holes for slurry drainage. The surface of the support plate 571 is also provided with a tubular structure in which the slurry is stored. When the output shaft of the third motor 510 is working, it drives the eccentric mechanism 572 through the belt and guide wheel. When the eccentric mechanism 572 is working, it drives the toothed plate 573 to slide back and forth in the vertical direction, and drives the piercing rod 574 to continuously approach and move away from the support plate 571, squeezing and piercing the slurry after drainage to form honeycomb briquettes.
