Description

Technical Field

[0001] This invention relates to the field of material crushing technology, and more specifically, to a crushing and arch-breaking system and method. Background Technology

[0002] As an indispensable piece of equipment in open-pit coal mining systems, crushing stations play a crucial role in the coal production process and are one of the core pieces of equipment in coal mine production systems.

[0003] Due to the unique environment of coal mines, crushing stations are susceptible to problems such as large pieces of material obstructing the flow or coal accumulating into arches, leading to crusher blockage or idling. Currently, these situations mostly require manual intervention, severely impacting crusher efficiency and increasing worker workload and safety risks. While existing open-pit mine crushing station systems meet certain coal crushing requirements, they lack auxiliary crushing stages for large coal and rock, further affecting production efficiency. Summary of the Invention

[0004] This invention provides a crushing and arch-breaking system and method to solve the problem that existing crushing and arch-breaking systems lack a large coal and rock auxiliary crushing and arch-breaking step.

[0005] To address the aforementioned problems, according to one aspect of the present invention, a crushing and arch-breaking system is provided. The system includes a crushing station, a mounting frame, an intercepting part, a limiting part, a cutting part, and an arch-breaking part. The crushing station has a crushing chamber for crushing materials and a material transfer area for transferring materials into the crushing chamber. The mounting frame spans the material transfer area and the crushing chamber. The intercepting part, the limiting part, and the cutting part are all located above the material transfer area near the crushing chamber. The intercepting part includes an intercepting component and a lifting component. One end of the lifting component is hinged to the mounting frame, and both ends of the intercepting component are connected to the mounting frame and the material transfer area, respectively, forming a mesh area for intercepting large pieces of material. The limiting part is hinged to the mounting frame to form a clamping area with adjustable volume and position for clamping large pieces of material. The cutting part is mounted on the mounting frame and includes at least one cutting roller extending into the clamping area. The position and placement angle of the cutting roller within the clamping area are adjustable. The arch-breaking part is movably mounted on the mounting frame and has an arch-breaking component extending into the crushing chamber.

[0006] Furthermore, the lifting component includes a first drive unit, a first bearing assembly, a first rotating frame, and multiple first claws fixedly mounted on the first rotating frame. The first rotating frame spans the material transfer area and is rotatably mounted on the mounting frame via the first drive unit and the first bearing assembly. The multiple first claws are parallel to each other and spaced apart. The first claws are arc-shaped structures that protrude towards the material transfer area.

[0007] Furthermore, there are three first claws. The interception assembly includes long chains and short chains. The ends of the two first claws on both sides are each connected to a short chain, and the other end of the short chain is connected to the side wall of the material transfer area on the same side. The end of the first claw in the middle is connected to two long chains, and the other ends of the two long chains are connected to the side walls of the material transfer area on both sides respectively. In the material transfer direction, the connection position of the long chain to the side wall of the material transfer area is behind the connection position of the short chain to the side wall of the material transfer area. The ends of the three first claws on the side away from the mounting frame float above the material transfer area, so that the two long chains and the two short chains form a mesh area.

[0008] Furthermore, the limiting part includes a second driving member, a second bearing assembly, a second rotating frame, and a plurality of second claws fixedly mounted on the second rotating frame. The second rotating frame spans the material transfer area and is rotatably mounted on the mounting frame through the second driving member and the second bearing assembly. The plurality of second claws are parallel to each other and spaced apart. The second claws are arc-shaped structures protruding in the direction away from the material transfer area. The extension directions of the plurality of first claws and the plurality of second claws are parallel and alternately arranged. The connection position between the first rotating frame and the mounting frame is located below the connection position between the second rotating frame and the mounting frame.

[0009] Furthermore, the first rotating frame includes a first rotating shaft, two first crossbeams, a first reinforcing rib plate, and a second reinforcing rib plate. The two first crossbeams are vertically arranged at both ends of the first rotating shaft and are hinged to the mounting frame. Multiple first claws are spaced apart on the first rotating shaft. A first reinforcing rib plate is provided between any one of the first crossbeams and the first rotating shaft and the first claw. A second reinforcing rib plate is provided between the sides of any two adjacent first claws facing away from the first rotating shaft. The second rotating frame includes a second rotating shaft, two second crossbeams, and a third reinforcing rib plate. The two second crossbeams are vertically arranged at both ends of the second rotating shaft and are hinged to the mounting frame. Multiple second claws are spaced apart on the second rotating shaft. A third reinforcing rib plate is provided between any one of the second crossbeams and the second rotating shaft and the second claw.

[0010] Furthermore, the top of the mounting frame has a first slide rail extending in the direction across the material transfer area, and the cutting part also includes an adjusting arm, one end of which is movably disposed within the first slide rail, and the cutting roller is rotatably disposed at the other end of the adjusting arm.

[0011] Furthermore, the adjusting arm includes a swing arm, a first long arm, a second long arm, and a first base. The cutting part also includes a first driving device, a second driving device, a third driving device, and a fourth driving device. The first base is disposed at one end of the first long arm and is slidably disposed on a first slide rail via the first driving device. One end of the second long arm is slidably disposed on one side of the first long arm along the extension direction of the first long arm via the second driving device. One end of the swing arm is oscillatingly disposed at the other end of the second long arm via the third driving device. The cutting roller is rotatably disposed at the other end of the swing arm via the fourth driving device.

[0012] Furthermore, the mounting frame has a second slide rail spanning the material transfer zone and the crushing chamber. The arch-breaking part also includes a third crossbeam, a second base, a guide device and a fifth drive device disposed below the third crossbeam. The guide device is slidably mounted on the second slide rail via the second base. The fifth drive device is disposed on one side of the guide device and drivenly connected to the third crossbeam to drive the third crossbeam to rise and fall relative to the guide device. The arch-breaking assembly includes longitudinal chains and transverse chains connected to each other. The longitudinal chains are connected to the third crossbeam. One end of the longitudinal chain connected to the transverse chain extends into the crushing chamber. Both ends of the transverse chain are fixedly disposed in the crushing chamber.

[0013] Furthermore, the crushing and arch-breaking system also includes a monitoring module, which includes a mounting base set on the mounting frame and a camera set on the mounting base. The camera's viewing direction is facing the clamping area and the viewing direction is adjustable.

[0014] According to another aspect of the present invention, a method for breaking up arches is provided, which is applied to the above-mentioned method for breaking up arches, and the method includes:

[0015] S1: Activate the lifting components to support the mesh area, which is used to intercept large pieces of material;

[0016] S2: The mesh area was detected to be blocking large pieces of material. The limit switch was activated to move the blocked large pieces of material to the lifting component.

[0017] S3: Controls the movement of the lifting component and lifts up the large pieces of material that have been intercepted;

[0018] S4: Start the cutting unit and cut the large pieces of material that have been intercepted using the cutting rollers;

[0019] S5: When the coal pile is too high and forms an arch, activate the arch-breaking section to break the arch in the crushing chamber.

[0020] In the absence of detection that the mesh area intercepted large pieces of material, the lifting component of the lifting component always swings at a certain frequency and angle to disperse and / or avoid the pile of material that was intercepted and accumulated in the mesh area of ​​the interception component.

[0021] The present invention provides a crushing and arch-breaking system, comprising a crushing station, a mounting frame, an intercepting part, a limiting part, a cutting part, and an arch-breaking part. The crushing station has a crushing chamber for crushing materials and a material transfer area for transferring materials to the crushing chamber. The mounting frame spans the material transfer area and the crushing chamber. The intercepting part, the limiting part, and the cutting part are all located above the material transfer area near the crushing chamber. The intercepting part includes an intercepting component and a lifting component. One end of the lifting component is hinged to the mounting frame, and both ends of the intercepting component are connected to the mounting frame and the material transfer area, respectively, forming a mesh area for intercepting large pieces of material. The limiting part is hinged to the mounting frame to form a clamping area with adjustable volume and position for clamping large pieces of material. The cutting part is mounted on the mounting frame and includes at least one cutting roller that extends into the clamping area. The position and placement angle of the cutting roller in the clamping area are adjustable. The arch-breaking part is movably mounted on the mounting frame and has an arch-breaking component extending into the crushing chamber.

[0022] This solution utilizes the mesh area of ​​the interception component to intercept large pieces of material, and the rotation of the lifting component to lift these large pieces to a certain height, separating them from the material flow. Furthermore, the rotation of the limiting part secures the large pieces, and adjusting the position and angle of the cutting rollers allows for the crushing of these fixed large pieces, ensuring reliable crushing processing. On the other hand, when coal transported from the conveyor zone to the crushing chamber accumulates in an arch, the arch-breaking part can break up the arched coal pile. This solution significantly improves the operational efficiency of open-pit mine crushing stations, reduces the labor intensity of workers, and enhances the economic benefits of coal mines.

[0038] 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. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0039] like Figures 1 to 6 As shown, an embodiment of the present invention provides a crushing and arch-breaking system, which includes a crushing station 10, a mounting frame 20, an interception part 30, a limiting part 40, a cutting part 50, and an arch-breaking part 60. The crushing station 10 has a crushing chamber 101 for crushing materials and a material transfer area 102 for transferring materials to the crushing chamber 101. The mounting frame 20 is arranged across the material transfer area 102 and the crushing chamber 101. The interception part 30, the limiting part 40, and the cutting part 50 are all located above the side of the material transfer area 102 near the crushing chamber 101. The interception part 30 includes an interception component 31 and a lifting component 32. One end of component 2 is hinged to the mounting frame 20. Both ends of the intercepting component 31 are connected to the mounting frame 20 and the material transfer area 102 respectively to form a mesh area for intercepting large pieces of material. The limiting part 40 is hinged to the mounting frame 20 to form a clamping area with adjustable volume and position for clamping large pieces of material with the lifting component 32. The cutting part 50 is disposed on the mounting frame 20. The cutting part 50 includes at least a cutting roller 51 that extends into the clamping area. The position and placement angle of the cutting roller 51 in the clamping area are adjustable. The arch breaking part 60 is movably disposed on the mounting frame 20 and has an arch breaking component 61 that extends into the crushing chamber 101.

[0040] This solution utilizes the mesh area of ​​the interception component 31 to intercept large pieces of material, and the rotation of the lifting component 32 to lift the large pieces to a certain height, thus separating them from the material flow. Furthermore, the rotation of the limiting part 40 secures the large pieces, and adjusting the position and angle of the cutting roller 51 allows for the crushing of the secured large pieces, ensuring reliable crushing processing. On the other hand, when coal transported from the conveying area 102 to the crushing chamber 101 accumulates into an arch, the arch-breaking part 60 can break up the arched coal pile. This solution significantly improves the operational efficiency of open-pit mine crushing stations, reduces the labor intensity of workers, and enhances the economic benefits of coal mines.

[0041] like Figure 1 and Figure 4 As shown, the lifting component 32 includes a first driving member 321, a first bearing assembly 322, a first rotating frame 323, and a plurality of first claws 324 fixedly mounted on the first rotating frame 323. The first rotating frame 323 spans the material transfer area 102 and is rotatably mounted on the mounting frame 20 through the first driving member 321 and the first bearing assembly 322. The plurality of first claws 324 are parallel to each other and spaced apart. The first claws 324 are arc-shaped structures that protrude toward the material transfer area 102.

[0042] This configuration allows the first driving component 321 to drive the first rotating frame 323, which in turn drives the rotation of multiple first claws 324 to lift large pieces of material. The lifting method is simple and the structure is reliable. On the other hand, the arc-shaped design of the first claws 324 helps to improve their stability when lifting large pieces of material.

[0043] like Figure 4 As shown, there are three first claws 324. The interception component 31 includes a long chain 311 and a short chain 312. The ends of the two first claws 324 on both sides are connected to a short chain 312. The other end of the short chain 312 is connected to the side wall of the material transfer area 102 on the same side. The end of the first claw 324 in the middle is connected to two long chains 311. The other ends of the two long chains 311 are connected to the side walls of the material transfer area 102 on both sides respectively. In the material transfer direction, the connection position of the long chain 311 to the side wall of the material transfer area 102 is behind the connection position of the short chain 312 to the side wall of the material transfer area 102. The ends of the three first claws 324 on the side away from the mounting frame 20 float above the material transfer area 102, so that the two long chains 311 and the two short chains 312 form a mesh area.

[0044] In this embodiment, the arc-shaped design of the first claw 324 helps to ensure the lifting of its end, thereby ensuring the forming effect of the mesh area and its interception effect on large pieces of material. It can be understood that the interception height of the mesh area can be adjusted by rotating the lifting component 32. On the other hand, limiting the number of first claws 324 helps to ensure their support and lifting effect on large pieces of material. This arrangement, with multiple chains forming a mesh area for intercepting large pieces of material, allows for adaptive adjustment of the chain connections and number according to actual conditions, thereby adjusting the mesh area. Simultaneously, using chains for interception can, to some extent, reduce the forward impact of large pieces of material, thus extending the service life of the interception component 31.

[0045] like Figure 1 and Figure 3 As shown, the limiting part 40 includes a second driving member 41, a second bearing assembly 42, a second rotating frame 43, and a plurality of second claws 44 fixedly mounted on the second rotating frame 43. The second rotating frame 43 spans the material transfer area 102 and is rotatably mounted on the mounting frame 20 through the second driving member 41 and the second bearing assembly 42. The plurality of second claws 44 are parallel and spaced apart. The second claws 44 are arc-shaped structures that protrude in the direction away from the material transfer area 102. The extension directions of the plurality of first claws 324 and the plurality of second claws 44 are parallel and alternately arranged. The connection position of the first rotating frame 323 and the mounting frame 20 is located below the connection position of the second rotating frame 43 and the mounting frame 20.

[0046] In this embodiment, there are two second claws 44, which are alternately arranged with three first claws 324 to ensure the restraint effect on large pieces of material. Similarly, the arc-shaped design of the second claws 44 helps improve their stability in fixing large pieces of material. Furthermore, the connection point between the first rotating frame 323 and the mounting frame 20 is located below the connection point between the second rotating frame 43 and the mounting frame 20 to avoid interference between them during rotation.

[0047] It should be noted that in this embodiment, two of the three first claws 324 are close to the two side walls of the material transfer area 102, the third first claw 324 is located in the middle area of ​​the material transfer area 102, the gap between any two first claws 324 is approximately equal to 1 / 2 of the material transfer area 102, and the two second claws 44 are respectively arranged in the middle area of ​​the two gaps formed by the three first claws 324. It is understood that this embodiment is mainly used to pick up large pieces of material whose radial dimension is larger than the gap between two adjacent first claws 324. After such large pieces of material are intercepted, they are lifted onto at least two first claws 324 by at least one second claw 44. Then, the two second claws 44 continue to perform the material-picking action and reduce the volume of the clamping area between them and the first claws 324 until the large pieces of material are clamped in the clamping area. Then, the cutting roller 51 cuts the large pieces of material clamped in the clamping area into multiple pieces of material whose radial dimension is smaller than the gap between two adjacent first claws 324. The cut pieces of material fall back into the material transfer area 102 from the gap between two adjacent first claws 324 and are transported to the crushing chamber 101.

[0048] On the other hand, due to the way the mesh area is set, it will also intercept some medium-sized materials whose radial dimensions are smaller than the gap between two adjacent first claws 324. In order to avoid the accumulation of such medium-sized materials that cannot pass directly through the mesh area but cannot be lifted, the lifting component 32 can be controlled to swing at a certain frequency and angle to repeatedly adjust the mesh area and promptly shovel away the small material piles formed, so as to ensure the normal conveying of medium-sized materials. When a large piece of material is detected to be blocked, a series of operations such as lifting, raising, and crushing can be performed.

[0049] like Figure 3 and Figure 4As shown, the first rotating frame 323 includes a first rotating shaft 3231, two first crossbeams 3232, a first reinforcing rib plate 3233, and a second reinforcing rib plate 3234. The two first crossbeams 3232 are vertically arranged at both ends of the first rotating shaft 3231 and are hinged to the mounting frame 20. Multiple first claws 324 are spaced apart on the first rotating shaft 3231. A first reinforcing rib plate 3233 is provided between any first crossbeam 3232 and the first rotating shaft 3231 and the first claw 324. Any two adjacent first claws... A second reinforcing rib 3234 is provided between the claw 324 and the side facing away from the first rotating shaft 3231; the second rotating frame 43 includes a second rotating shaft 431, two second crossbeams 432 and a third reinforcing rib 433. The two second crossbeams 432 are vertically arranged at both ends of the second rotating shaft 431 and are hinged to the mounting frame 20. Multiple second claws 44 are spaced apart on the second rotating shaft 431. A third reinforcing rib 433 is provided between any second crossbeam 432 and the second rotating shaft 431 and the second claw 44. This arrangement helps to ensure the structural strength of the first rotating frame 323 and the second rotating frame 43 themselves, as well as the connection strength between the two and the mounting frame 20, and ensures the reliability and stability of the intercepting part 30 and the limiting part 40.

[0050] like Figure 1 and Figure 5 As shown, the top of the mounting bracket 20 has a first slide rail 201 extending in the direction across the material transfer area 102, and the cutting part 50 also includes an adjusting arm 52, one end of which is movably disposed in the first slide rail 201, and the cutting roller 51 is rotatably disposed at the other end of the adjusting arm 52.

[0051] This configuration allows for adjustment of the position of the cutting roller 51 in the direction spanning the material transfer zone 102 by moving the adjusting arm 52 on the first slide rail 201, thereby improving the applicability of the cutting roller 51.

[0052] like Figure 5As shown, the adjusting arm 52 includes a swing arm 521, a first long arm 522, a second long arm 523, and a first base 524. The cutting section 50 also includes a first driving device 53, a second driving device 54, a third driving device 55, and a fourth driving device 56. The first base 524 is disposed at one end of the first long arm 522 and slidably mounted on the first slide rail 201 via the first driving device 53. One end of the second long arm 523 is slidably disposed on one side of the first long arm 522 along its extension direction via the second driving device 54. One end of the swing arm 521 is oscillatingly disposed at the other end of the second long arm 523 via the third driving device 55. The cutting roller 51 is rotatably disposed at the other end of the swing arm 521 via the fourth driving device 56. This configuration allows the cutting roller 51 to move not only along the direction spanning the material transfer area 102 but also along the extension direction of the first long arm 522 and oscillate up and down, thereby achieving multi-degree-of-freedom adjustment of the cutting roller 51 and further improving its applicability.

[0053] The cutting rollers 51 consist of two units, which are coaxially arranged to improve the crushing effect.

[0054] like Figure 1 and Figure 6 As shown, the mounting frame 20 has a second slide rail 202 spanning the material transfer area 102 and the crushing chamber 101. The arch-breaking part 60 also includes a third crossbeam 62, a second base 65, and a guide device 63 and a fifth drive device 64 disposed below the third crossbeam 62. The guide device 63 is slidably disposed on the second slide rail 202 via the second base 65. The fifth drive device 64 is disposed on one side of the guide device 63 and is drivenly connected to the third crossbeam 62 to drive the third crossbeam 62 to rise and fall relative to the guide device 63. The arch-breaking assembly 61 includes a longitudinal chain 611 and a transverse chain 612 connected to each other. The longitudinal chain 611 is connected to the third crossbeam 62. One end of the longitudinal chain 611 connected to the transverse chain 612 extends into the crushing chamber 101. Both ends of the transverse chain 612 are fixedly disposed in the crushing chamber 101.

[0055] In this embodiment, the second base 65, the fifth drive device 64, and the guide device 63 are integrally arranged in two sets and positioned below both ends of the third crossbeam 62. The third crossbeam 62 is vertically and flexibly positioned on top of the guide device 63. The fifth drive device 64 enables the lifting and lowering of the third crossbeam 62. Combined with the sliding of the arch-breaking part 60 along the second slide rail 202, the longitudinal chain 611 and the transverse chain 612 vibrate, thereby achieving the arch-breaking operation of the coal pile that has formed an arch in the crushing chamber 101. There are four longitudinal chains 611, divided into two groups, with the two groups of longitudinal chains 611 positioned on both sides of the middle area below the third crossbeam 62. There are two transverse chains 612, each positioned below the two groups of longitudinal chains 611. Both ends of the transverse chains 612 are fixedly positioned within the crushing chamber 101. Specifically, due to the fixed end of the horizontal chain 612, when the third crossbeam 62 is reciprocated, the longitudinal chain 611 and the horizontal chain 612 will swing back and forth around the installation position of the horizontal chain 612, and the horizontal chain 612 will be reciprocated and stretched, thereby breaking the arch of the material pile in the crushing chamber 101. Furthermore, when the third crossbeam 62 is raised and lowered, the longitudinal chain 611 will be raised and lowered as a whole and the horizontal chain 612 will be reciprocated and stretched. Combined with the reciprocating movement adjustment of the third crossbeam 62, the longitudinal chain 611 and the horizontal chain 612 will vibrate, which is beneficial to improving the arch breaking effect of the material pile in the crushing chamber 101.

[0056] like Figure 1 and Figure 6 As shown, the crushing and arch-breaking system also includes a monitoring module 70. The monitoring module 70 includes a mounting base 71 mounted on the mounting frame 20 and a camera 72 mounted on the mounting base 71. The camera 72's viewing direction is towards the clamping area and is adjustable. This configuration allows for monitoring of the clamping area via the camera 72, facilitating observation and timely adjustments by the operator. In this embodiment, two monitoring modules 70 are used, respectively positioned on either side of the mounting frame 20 spanning the material transfer area 102.

[0057] Another embodiment of the present invention provides a method for breaking up and arching systems, which is applied to the above-mentioned system. The method includes:

[0058] S1: Activate the lifting component 32 to support the mesh area, which is used to intercept large pieces of material;

[0059] S2: The mesh area was detected to have intercepted a large piece of material. The limit unit 40 was activated to transfer the intercepted large piece of material to the lifting component 32.

[0060] S3: Control the movement of the lifting component 32 and lift the large pieces of material that have been intercepted;

[0061] S4: Start the cutting unit 50 and cut the large pieces of material that have been intercepted by the cutting roller 51;

[0062] S5: When the coal pile is too high and forms an arch, start the arch-breaking section 60 to break the arch of the material in the crushing chamber 101.

[0063] In the absence of detection that the mesh area has intercepted large pieces of material, the lifting component 32 always swings at a certain frequency and angle to disperse and / or avoid the pile of material that has been intercepted and accumulated in the mesh area of ​​the interception component 31.

[0064] Specifically, in this embodiment, when the monitoring module 70 detects a large piece of material (material with a radial dimension larger than the gap between two adjacent first claws 324), the large piece of material is first intercepted by the mesh area formed by the long chain 311 and short chain 312 of the interception part 30; then, the second driving member 41 of the limiting part 40 is controlled to rotate the second rotating frame 43 and the second claw 44 clockwise by a certain angle to transfer the large piece of material to the interception part 30; the first driving member 321 of the interception part 30 is controlled to rotate the first rotating frame... 323 and the first claw 324 rotate clockwise at a certain angle to complete the interception and lifting of large pieces of material. Then, the position of the cutting roller 51 is adjusted according to the actual situation, and the cutting roller 51 is controlled to rotate and cut large pieces of material. During this process, coal may accumulate into an arch. At this time, the arch-breaking part 60 is activated, and the third crossbeam 62 is controlled to move up and down and / or slide back and forth along the second slide rail 202 to shake the longitudinal chain 611 and the transverse chain 612 and realize the arch-breaking operation of the coal pile entering the crushing chamber 101. On the other hand, when no large pieces of material are detected, in order to avoid the accumulation of medium-sized materials (i.e., materials that will be intercepted by the mesh area but whose radial dimension is smaller than the gap between two adjacent first claws 324 and cannot be lifted) in the mesh area, the lifting component 32 can be controlled to swing at a certain frequency and angle to repeatedly adjust the mesh area and promptly shovel away the small material piles formed.
