Description

Technical Field

[0001] The invention relates to the technical field of coal block crushing and processing, and in particular provides a coal block cleaning device under a mobile belt conveyor. Background Art

[0002] In the field of bulk material transportation on belt conveyors, especially in the long-distance transportation of highly viscous and brittle materials such as coal and ore, large pieces of material frequently fall off the edge of the belt due to their own gravity and belt vibration and accumulate under the frame, forming a floating coal problem that is difficult to solve.

[0003] While traditional solutions attempt to reduce material scattering by adding devices like coal baffles and scrapers, they fail to address the secondary processing challenge of already detached large lumps of coal. Firstly, if the detached large lumps of coal are manually backfilled onto the running belt without being crushed, they can repeatedly fall off at belt undulations, drum turning points, and vibrating screening stages due to oversize, sharp edges, or poor surface adhesion. This creates a vicious cycle of "falling off, backfilling, and falling off again," severely reducing transport efficiency and increasing equipment wear. On the other hand, fixed crushing stations need to interrupt the belt operation and transfer large pieces of coal for centralized processing, resulting in downtime losses and secondary pollution. Mobile crushing equipment is difficult to put into practical use due to problems such as the inability to coordinate with the belt conveyor cleaning operation, poor compatibility between the crushed particle size and the belt load (such as excessive powder discharge from the hammer crusher or uneven particle size of the jaw crusher), and sticky and wet materials clogging the rotor.

[0004] More importantly, the crushing equipment is often independent of the cleaning system, resulting in large pieces of coal continuing to be spilled during the collection and transportation process, and the crushed materials cannot be seamlessly returned to the belt flow due to the lack of a precise backfilling mechanism.

[0005] This field urgently needs an innovative solution that can move and operate under the belt conveyor, crush large floating coal in real time, accurately control the output particle size and realize automatic closed-loop backfilling of crushed coal, so as to fundamentally solve the stubborn problem of large coal falling again.

DETAILED DESCRIPTION

[0030] In order to make the purpose, scheme and advantages of the technical solution of the present invention more clear, the technical solution of the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings of specific embodiments of the present invention. Unless otherwise specified, the terms used herein have the common meanings in the art. The same reference numerals in the drawings represent the same components.

[0031] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0032] As described above, in the traditional cleaning of floating coal under the belt conveyor, since manpower is required for cleaning, the belt conveyor often drops coal blocks, causing physical harm to personnel, and the problem of repeated falling of large-volume coal blocks often occurs when they are repeatedly loaded on the belt conveyor.

[0033] In order 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 coal block cleaning device under a mobile belt conveyor, which includes: a first mobile platform 100 and a second mobile platform 200 installed on one side of the first mobile platform 100 through a connecting frame 300; and also includes: a coal picking mechanism 400 arranged on the first mobile platform 100 and a coal block crushing mechanism 500 arranged on the second mobile platform 200; wherein: the coal picking mechanism 400 includes a reciprocating clamping mechanism 410 arranged close to the ground, and a first feeding mechanism 420 whose feeding end is arranged in the clamping area of ​​the reciprocating clamping mechanism 410, and the output end of the first feeding mechanism 420 is arranged close to the feeding port of the coal block crushing mechanism 500; a second feeding mechanism 600 is provided between the first mobile platform 100 and the second mobile platform 200, and a third feeding mechanism 700 is provided at the output end of the coal block crushing mechanism 500, and the output end of the third feeding mechanism 700 is arranged toward the upper part of the belt conveyor.

[0034] In the above embodiment, the first mobile platform 100 is connected to the second mobile platform 200 by a connecting frame 300, so that the first mobile platform 100 and the second mobile platform 200 move at the same time, and the first mobile platform 100 and the second mobile platform 200 move back and forth in the field below the belt conveyor. During the movement of the first mobile platform 100, the reciprocating clamping mechanism 410 of the coal picking mechanism 400 is driven to work continuously, and the coal blocks enter the holding area of ​​the reciprocating clamping mechanism 410, and the reciprocating clamping mechanism 410 clamps the coal blocks and pushes them to the second mobile platform 100. At the feeding port of a feeding mechanism 420, the first feeding mechanism 420 extracts the coal blocks into the second feeding mechanism 600. After passing through the second feeding mechanism 600, the coal blocks enter the coal block crushing mechanism 500 installed on the second mobile platform 200. The coal blocks are crushed by the coal block crushing mechanism 500, and then the crushed coal blocks are lifted up by the third feeding mechanism 700 and placed again on the conveyor belt surface. The large coal blocks that are easy to fall off are then crushed by the coal block crushing mechanism 500, and are placed repeatedly on the conveyor belt surface to prevent them from falling off again.

[0035] It realizes the automatic continuous cleaning, crushing and backfilling of scattered coal blocks under the belt conveyor (especially large coal blocks that are prone to repeated falling off), significantly improving the cleaning efficiency, ensuring the continuous and stable operation of the belt conveyor system, and effectively reducing the safety risks and labor intensity of manual cleaning.

[0036] The reciprocating clamping mechanism 410 on the first mobile platform 100 cooperates with the first loading mechanism 420 to directly grab and lift the loose coal on the ground, replacing the traditional inefficient and dangerous manual raking or simple mechanical collection.

[0037] Secondly, a coal crushing mechanism 500 is integrated on the synchronously moving second mobile platform 200, which can instantly crush the collected large coal into a particle size suitable for transportation, improving the problem of large coal repeatedly falling off the belt due to size or poor adhesion, causing repeated accumulation and cleaning.

[0038] Finally, the crushed coal is directly backfilled onto the upper part of the running belt conveyor through the third loading mechanism 700, forming a closed-loop automated process of "collection-crushing-return". This not only shortens the cleaning cycle and avoids belt shutdown caused by cleaning, but also reduces secondary spillage and dust pollution during material transfer. At the same time, the entire device can be flexibly moved along the belt conveyor, with a wide coverage range and stronger adaptability, thus comprehensively realizing safe, efficient and low-consumption floating coal control.

[0039] See also Figures 1-6In some embodiments, the first mobile platform 100 includes: a first base plate 110, which is arranged on one side of the second mobile platform 200; and a plurality of universal wheels 120, which are evenly distributed on the bottom surface of the first base plate 110; a first box body 130, which is covered on the upper part of the first base plate 110, and the first loading mechanism 420 is arranged in the first box body 130; the second mobile platform 200 includes: a second base plate 210, which is arranged on one side of the first base plate 110; a crawler wheel mechanism 220, which is installed on the bottom surface of the second base plate 210; a second box body 230, which is covered on the upper part of the second base plate 210, and the coal block crushing mechanism 500 is installed in the second box body 230.

[0040] 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, and the first box body 130 and the second box body 230 are covered on the outside of the first feeding mechanism 420 and the coal crushing mechanism 500. When the second mobile platform 200 turns, the two sets of tracks of the track wheel mechanism 220 adjust the rotation direction. When the second mobile platform 200 turns, the first mobile platform 100 is driven to rotate around the second mobile platform 200 through the connecting frame 300. When the first mobile platform 100 rotates, each universal wheel 120 rotates in the direction of the bottom surface of the first base plate 110, thereby achieving the purpose of simultaneous steering of the first mobile platform 100 and the second mobile platform 200. The track wheel mechanism 220 installed under the second mobile 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.

[0041] See also Figures 1-6 In some embodiments, the reciprocating clamping mechanism 410 includes: a first motor 411, mounted on the inner wall of the first box body 130; and a crank mechanism 412, connected to the drive shaft belt of the first motor 411, with both ends of the crank mechanism 412 rotatably connected to the inner wall of the first box body 130, and the middle section of the crank mechanism 412 is U-shaped; a first driving rod 413, one end of which is hinged to the U-shaped section of the crank mechanism 412; L-shaped clamping claws 414, symmetrically arranged on both sides of the first driving rod 413 along the axis of the first driving rod 413; a sleeve 415, sleeved on the first The driving rod 413 is close to the circumferential outer wall of one end of the L-shaped clamp 414; the first connecting rod 416, one end of which is hinged to the circumferential outer wall of the sleeve 415, and the other end is hinged to one end of the L-shaped clamp 414; the vertical rod 417, the middle section of which is connected to the end wall of the first driving rod 413 close to the L-shaped clamp 414, and the axis of the vertical rod 417 is perpendicular to the axis of the first driving rod 413; the second connecting rod 418, one end of which is hinged to one end of the vertical rod 417, and the other end is hinged to the corner of the L-shaped clamp 414; wherein: the sleeve 415 is installed in the first box body 130.

[0042] In the above embodiment, when the reciprocating clamping mechanism is driven to work, the output shaft of the first motor 411 rotates, and one end of the toggle mechanism 412 is driven to rotate through the belt, so that the toggle mechanism 412 rotates on the inner wall of the first box body 130. When the U-shaped section of the first driving rod 413 rotates, it drives the first driving rod 413 to move back and forth in the sleeve 415. When the first driving rod 413 moves back and forth, it drives the vertical rod 417 and the second connecting rod 418 to move in the direction close to the sleeve 415. At this time, the U-shaped section of the toggle mechanism 412 swings to the lowest point, pulling the end of the first driving rod 413 close to the toggle mechanism 412 to swing downward, and the other end of the first driving rod 413 The end is tilted, so that the first driving rod 413 drives the L-shaped clamping claw 414 to lift upward. At the same time, when the vertical rod 417 moves toward the direction of the sleeve 415, the second connecting rod 418 drives the corner of the L-shaped clamping claw 414 to move closer to the center, so as to achieve the purpose of clamping the coal block. Then, the coal block can be clamped and lifted and placed in the feeding port of the first feeding mechanism 420. It is worth mentioning that the two sides of the sleeve 415 are hinged to the inner wall of the first box body 130, so that the sleeve 415 can rotate in its own length direction, thereby driving the L-shaped clamping claw 414 to swing around the length direction of the sleeve 415, thereby achieving the effect of lifting the clamped coal block.

[0043] See also Figures 1-6 In some embodiments, the first feeding mechanism 420 includes: a first spiral feeding roller 421, which is vertically arranged between the two L-shaped clamps 414; a first sleeve 422, which is covered on 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, which is installed on the first box body 130, and the output shaft of the first motor 411 is drive-connected to the top end of the first spiral feeding roller 421; a bucket 424 is also provided on the side of the first box body 130 close to the L-shaped clamp 414, and a coal storage tank 425 is provided on the surface of the bucket 424, and the bottom end of the first spiral feeding roller 421 is arranged in the coal storage tank 425.

[0044] In the above embodiment, the first feeding mechanism 420 works continuously when the reciprocating clamping mechanism works. When the first feeding mechanism 420 works, the output shaft of the second motor 423 rotates through the gear set to drive the first spiral feeding roller 421 to rotate continuously in the first sleeve 422. The bottom end of the first spiral feeding roller 421 rotates in the coal storage trough 425. The bucket 424 shovels the coal blocks on its surface as the first base plate 110 moves. The L-shaped clamping jaws 414 clamp the coal blocks and place 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 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.

[0045] See also Figures 1-6In some embodiments, a material guide channel 426 is further provided on the top surface of the first box body 130; one end of the material guide channel 426 is arranged close to the first spiral feeding roller 421, and a common jaw crusher 427 is provided at the lower part of the other end; the common jaw crusher 427 is installed in the first box body 130; the output end located at the lower part of the common jaw crusher 427 is arranged at the feeding end of the second feeding mechanism 600; wherein: the driving shaft of the common jaw crusher 427 is connected to the output shaft belt of the first motor 411.

[0046] 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, and after passing through the guide channel 426, falls into the upper input end of the common jaw crusher 427. The coal block is initially squeezed and crushed by the common jaw crusher 427. The crushed coal block falls from the bottom of the common jaw crusher 427 into the feed end of the second feeding mechanism 600, and is lifted and transported by the second feeding mechanism 600 to the coal block crushing mechanism 500 in the second box body 230 for secondary crushing. The common jaw crusher 427 is driven by the first motor 411.

[0047] See also Figures 1-6 ,In some embodiments, the coal crushing mechanism 500 includes: a third motor 510, installed in the second box 230; The hammer crusher 520 is installed in the second housing 230 , and the third motor 510 is connected to the crushing roller belt of the hammer crusher 520 ; A first screen 530 , which has a U-shaped cross section and is disposed near the lower portion of the crushing rod of the hammer crusher 520 ; The second screen 540 is provided below the first screen 530; The 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 of the third motor 510 by a belt; The horizontal conveying mechanism 560 is provided at the lower portion of the second screen 540 , the upper portion of the horizontal conveying mechanism 560 is open, and the working portion of the horizontal conveying mechanism 560 is connected to the output shaft belt of the third motor 510 .

[0048] In the above embodiment, when the output shaft of the third motor 510 rotates, the crushing rods of the hammer crusher 520 are driven to rotate through the belt. The output end of the second feeding mechanism 600 is set above the hammer crusher 520. When the crushing rods rotate, the coal blocks discharged by the second feeding mechanism 600 are knocked to achieve the effect of secondary crushing. The crushed coal blocks pass through the first screen 530 and fall into the second screen 540. If the size of the coal blocks does not allow them to pass through the first screen 530 and enter the second screen 540, the large-sized coal blocks above the first screen 530 are continuously knocked and crushed by the crushing rods until the coal blocks are of a size that can pass through the first screen 530 and enter the second screen 540. 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 drives the second screen 540 to vibrate continuously to prevent the coal blocks from clogging the holes of the second screen 540. Furthermore, the second screen 540 is tilted downward at one end close to the third feeding mechanism 700, and the large pieces of coal falling on the surface of the second screen 540 are continuously vibrated by the second screen 540, so that the large pieces of coal can smoothly enter the feeding port at the bottom end of the third feeding mechanism 700, and these coal blocks are lifted by the third feeding mechanism 700 and discharged to the belt conveyor from the discharging port at the top end of the third feeding mechanism 700.

[0049] The pulverized coal after passing through the second screen 540 falls into the horizontal conveying mechanism 560, and the horizontal conveying mechanism 560 transports the fallen coal blocks to the input end of the third feeding mechanism 700. After being fed by the third feeding mechanism 700, the coal blocks are discharged onto the conveyor belt.

[0050] See also Figures 1-6 In some embodiments, the horizontal conveying mechanism 560 includes: a second spiral loading roller 561, which is horizontally arranged along the length direction of the second screen 540; a plurality of dial plates 563, which are respectively arranged between the spiral blades 562 of the second spiral loading roller 561; a receiving plate 564, which is arranged on the lower outer wall of the second spiral loading roller 561; wherein: the second spiral loading roller 561 is connected to the output shaft belt of the third motor 510; the receiving plate 564 is arranged at an end away from the third motor 510 and close to the input end of the third loading mechanism 700.

[0051] In the above embodiment, when the output shaft of the third motor 510 rotates, the horizontally arranged second spiral feeding roller 561 is driven by a belt to rotate around its own axis, thereby driving the spiral blades 562 arranged on its circumferential outer wall to rotate, and the coal blocks are pushed from one end of the spiral blades 562 to the other end.
