[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work 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 arch breaking system, which includes a crushing station 10, a mounting frame 20, an intercepting portion 30, a limiting portion 40, a cutting portion 50 and an arch breaking portion 60. The crushing station 10 has a crushing cavity 101 for crushing materials and a material transfer area 102 for transferring materials into the crushing cavity 101. The mounting frame 20 is arranged across the material transfer area 102 and the crushing cavity 101. The intercepting portion 30, the limiting portion 40 and the cutting portion 50 are all located above the material transfer area 102 near the crushing cavity 101. The intercepting portion 30 includes an intercepting component 31 and a lifting component 32. The lifting component 33 2 is hinged to the mounting frame 20, and the two ends of the interception component 31 are respectively connected to the mounting frame 20 and the material transfer area 102 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 arranged on the mounting frame 20, and the cutting part 50 includes at least a cutting hob 51 extending into the clamping area, and the position and placement angle of the cutting hob 51 in the clamping area are adjustable; the arch breaking part 60 is movably arranged on the mounting frame 20 and has an arch breaking component 61 extending into the crushing chamber 101.

[0040] By adopting this solution, the large pieces of materials can be intercepted by the mesh area of ​​the interception component 31, and the large pieces of materials can be lifted to a certain height by the rotation of the lifting component 32, so as to separate the large pieces of materials from the material flow. Furthermore, the large pieces of materials can be fixed by the rotation of the limiter 40, and the fixed large pieces of materials can be crushed by adjusting the position and placement angle of the cutting hob 51, thereby ensuring the reliability of the crushing process of the large pieces of materials. On the other hand, when the coal material transported from the material transfer area 102 to the crushing chamber 101 is piled up into an arch, the arch breaking operation of the coal pile piled up into an arch can be achieved by the arch breaking part 60. This solution can greatly improve the operating efficiency of the open-pit mine crushing station, reduce the labor intensity of workers, and improve the economic benefits of the coal mine.

[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 arranged 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 and spaced apart in pairs, and the first claws 324 are arc-shaped structures protruding toward the material transfer area 102.

[0042] In this way, the first rotating frame 323 is driven by the first driving member 321, and then the first claws 324 are driven to rotate, so as to pick up large pieces of materials. The picking method is simple and the structure is reliable. On the other hand, the arc design of the first claws 324 is conducive to improving the stability of picking up large pieces of materials.

[0043] like Figure 4 As shown, there are three first claws 324, and the interception component 31 includes a long chain 311 and a short chain 312. The ends of the two first claws 324 located on both sides are respectively connected to a short chain 312, and the other end of the short chain 312 is connected to the side wall of the material transfer area 102 on its side. The end of the first claw 324 located in the middle is connected to the two long chains 311, and the other ends of the two long chains 311 are respectively connected to the side walls of the material transfer area 102. In the material transfer direction, the connection position between the long chain 311 and the side wall of the material transfer area 102 is located behind the connection position between the short chain 312 and the side wall of the material transfer area 102. The ends of the three first claws 324 facing 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 is also conducive to ensuring the lifting of its end, thereby ensuring the shaping effect of the mesh area and the interception effect of the mesh area on bulk materials. 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, by limiting the number of the first claws 324, it is conducive to ensuring its support and lifting effect on bulk materials. In this way, a mesh area for intercepting bulk materials is formed by multiple chains, which is conducive to adaptively adjusting the connection conditions and quantity of the chains according to actual conditions, thereby achieving the adjustment of the mesh area. At the same time, the use of chains for interception can slow down the impact of bulk materials forward to a certain extent, which is conducive to extending the service life of the interception component 31.

[0045] like Figure 1 and Figure 3 As shown, the limiting portion 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 arranged 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 in pairs. 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, and the two second claws 44 and the three first claws 324 are alternately arranged to ensure the limiting effect on the bulk material. Similarly, the arc-shaped design of the second claws 44 is conducive to improving the stability of the bulk material fixation. On the other hand, 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 to avoid the mutual interference between the two during the rotation process.

[0047] It should be noted that, two of the three first claws 324 in this embodiment 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 can be understood that the present embodiment is mainly used for picking up and crushing large pieces of material whose radial dimensions are larger than the gap between two adjacent first claws 324. After being intercepted, such large pieces of material are lifted onto at least two first claws 324 by at least one second claw 44. Thereafter, 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 large pieces of material clamped in the clamping area are cut by the cutting roller 51 to cut the large pieces of material into multiple small pieces of material whose radial dimensions are smaller than the gap between two adjacent first claws 324. The cut small pieces of material fall back from the gap between two adjacent first claws 324 to the material transfer area 102 and are transported to the crushing chamber 101.

[0048] On the other hand, due to the setting method of the mesh area, 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 medium-sized materials that cannot directly pass through the mesh area but cannot be picked up in the mesh area, the lifting component 32 can be controlled to always swing at a certain frequency and a certain angle to repeatedly adjust the mesh area and promptly shovel away the small material piles formed, thereby ensuring the normal transportation of medium-sized materials. When it is detected that large pieces of materials are blocked, a series of operations such as lifting, lifting, 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 cross beams 3232, a first reinforcing rib plate 3233 and a second reinforcing rib plate 3234. The two first cross beams 3232 are vertically arranged at both ends of the first rotating shaft 3231 and are both hinged on the mounting frame 20. A plurality of first claws 324 are arranged on the first rotating shaft 3231 at intervals. A first reinforcing rib plate 3233 is arranged between any first cross beam 3232 and the first rotating shaft 3231 and the first claws 324. Any two adjacent first claws 324 are connected to each other. A second reinforcing rib plate 3234 is arranged between the claws 324 on the side away from the first rotating shaft 3231; the second rotating frame 43 includes a second rotating shaft 431, two second cross beams 432 and a third reinforcing rib plate 433, the two second cross beams 432 are vertically arranged at both ends of the second rotating shaft 431 and are both hinged on the mounting frame 20, a plurality of second claws 44 are arranged at intervals on the second rotating shaft 431, and a third reinforcing rib plate 433 is arranged between any second cross beam 432 and the second rotating shaft 431 and the second claws 44. Such an arrangement is conducive to ensuring the structural strength of the first rotating frame 323 and the second rotating frame 43 themselves and the connection strength between the two and the mounting frame 20, and ensuring the reliability and stability of the intercepting portion 30 and the limiting portion 40.

[0050] like Figure 1 and Figure 5 As shown, the top of the mounting frame 20 has a first slide rail 201 extending in a direction across the material transfer area 102, and the cutting portion 50 also includes an adjusting arm 52, one end of the adjusting arm 52 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] With this arrangement, the position of the cutting roller 51 in a direction across the material transfer area 102 can be adjusted 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, and the cutting part 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 arranged at one end of the first long arm 522 and is slidably arranged on the first slide rail 201 through the first driving device 53. One end of the second long arm 523 is slidably arranged on one side of the first long arm 522 along the extension direction of the first long arm 522 through the second driving device 54. One end of the swing arm 521 is swingably arranged at the other end of the second long arm 523 through the third driving device 55. The cutting roller 51 is rotatably arranged at the other end of the swing arm 521 through the fourth driving device 56. In this way, the cutting roller 51 can not only move in the direction across the material transfer area 102, but also move in the extension direction of the first long arm 522 and swing up and down, so as to realize the multi-degree-of-freedom adjustment of the cutting roller 51, and further improve the applicability of the cutting roller 51.

[0053] There are two cutting rollers 51, 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 portion 60 also includes a third beam 62, a second base 65, and a guide device 63 and a fifth drive device 64 arranged below the third beam 62, the guide device 63 is slidably arranged on the second slide rail 202 through the second base 65, the fifth drive device 64 is arranged on one side of the guide device 63 and is drivingly connected to the third beam 62 to drive the third beam 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 beam 62, one end of the longitudinal chain 611 connected to the transverse chain 612 extends into the crushing chamber 101, and both ends of the transverse chain 612 are fixedly arranged 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 provided in two groups and are arranged below the two ends of the third crossbeam 62. The third crossbeam 62 is arranged on the top of the guide device 63 so as to be liftable. The lifting and lowering drive of the third crossbeam 62 can be realized by the fifth drive device 64. In combination with the sliding of the arch breaking part 60 along the second slide rail 202, the longitudinal chain 611 and the transverse chain 612 are shaken, thereby realizing the arch breaking operation of the coal pile accumulated into an arch in the crushing chamber 101. Among them, the number of longitudinal chains 611 is 4 and is divided into two groups. The two groups of longitudinal chains 611 are arranged on both sides of the middle area below the third crossbeam 62. The number of transverse chains 612 is 2. The two transverse chains 612 are respectively arranged below the two groups of longitudinal chains 611. Both ends of the transverse chain 612 are fixedly arranged in the crushing chamber 101. Specifically, due to the fixation of the end of the transverse chain 612, when the third crossbeam 62 is adjusted to move back and forth, the longitudinal chain 611 and the transverse chain 612 will swing back and forth around the installation position of the transverse chain 612, and the transverse chain 612 will be stretched back and forth at the same time, so as to achieve the arch breaking of the material pile in the crushing chamber 101; further, when the third crossbeam 62 is adjusted to rise and fall, the longitudinal chain 611 will be lifted and lowered as a whole and the transverse chain 612 will be stretched back and forth, and the reciprocating movement of the third crossbeam 62 will be adjusted to achieve the shaking of the longitudinal chain 611 and the transverse chain 612, which is beneficial to improve 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, which includes a mounting seat 71 arranged on the mounting frame 20 and a camera 72 arranged on the mounting seat 71, and the camera 72 is directed toward the clamping area and the camera direction is adjustable. In this way, the clamping area is monitored by the camera 72, which is convenient for the operator to observe and make adjustments in time. In this embodiment, there are two monitoring modules 70, and the two monitoring modules 70 are respectively arranged on both sides of the mounting frame 20 across the material transfer area 102.

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

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

[0059] S2: It is detected that a large piece of material is intercepted in the mesh area, and the limiting part 40 is started to push the intercepted large piece of material to the lifting component 32;

[0060] S3: Control the movement of the lifting component 32 to lift the intercepted bulk material;

[0061] S4: Start the cutting unit 50 to cut the intercepted bulk material by the cutting roller 51;

[0062] S5: When the coal pile height is too high and forms an arch, the arch breaking unit 60 is started to break the arch of the material in the crushing chamber 101;

[0063] In which, when no large pieces of material are intercepted in the mesh area, the lifting component 32 of the lifting component 32 always swings at a certain frequency and a certain angle to break up and / or avoid the material pile intercepted and accumulated in the mesh area of ​​the interception component 31.

[0064] Specifically, in the present embodiment, when the monitoring module 70 detects a large piece of material (a material whose radial dimension is 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 the 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 deliver 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 by a certain angle; the interception and lifting operation of the large block material is completed; 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 the large block material; in this process, the coal material is likely to accumulate into an arch, and at this time, the arch breaking part 60 is correspondingly started to control the third crossbeam 62 to rise and fall 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 block material is detected, in order to avoid the accumulation of medium block materials (i.e., materials that will be intercepted by the mesh area but have a radial size smaller than the gap between the two adjacent first claws 324 and cannot be lifted) in the mesh area, the lifting component 32 can be controlled to always swing at a certain frequency and a certain angle to repeatedly adjust the mesh area and timely shovel the small material piles formed.
