Description

Technical Field

[0001] The utility model relates to the technical field of scraper conveyors, in particular to a scraper conveyor debris removal device and a scraper conveyor. Background Art

[0002] Currently, conveyors that use scraper chains to move bulk materials within a trough are called scraper conveyors, also known as scraper transporters. In today's coal mining face, scraper conveyors not only transport coal and materials but also serve as the operating track for the shearer, making them an indispensable piece of equipment in modern coal mining. Continuous operation of the scraper conveyor ensures normal production. Otherwise, the entire coal mining face would be shut down, disrupting operations.

[0003] The fully mechanized mining machine cuts the coal seam into pieces, and the broken coal falls into the scraper conveyor, which transports the coal to the rear. When today's fully mechanized mining machines are cutting coal, the anchor rods, anchor net fragments and other debris left in the coal seam will fall into the scraper conveyor, and sometimes get stuck under the scraper and chain. Once it is caught in the head of the scraper conveyor, there is a risk of causing shutdown and injury. Therefore, it is necessary to remove the stuck anchor rods, anchor net fragments and other debris from the scraper conveyor in time.

[0004] However, the conventional method in the prior art is to remove the debris by dragging it with a manual hoist. This method requires manual installation of the manual hoist and dragging, which is time-consuming and labor-intensive and inconvenient to use. Utility Model Content

[0057] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0058] like Figures 1 to 8As shown, one embodiment of the present invention provides a debris removal device for a scraper conveyor, the debris removal device for a scraper conveyor comprising: a support base 10, a clamping drive unit 20, a first clamping arm 31, a second clamping arm 32, a first cutter head 41, and a second cutter head 42. The support base 10 is used to connect to the main body of the scraper conveyor. The clamping drive unit 20 is driven and connected to the first clamping arm 31 and the second clamping arm 32. The first clamping arm 31 includes a first connecting portion 311 and a first clamping portion 312 connected to each other. The second clamping arm 32 includes a second connecting portion 321 and a second clamping portion 322 connected to each other. An end of the first connecting portion 311 away from the first clamping portion 312 and an end of the second connecting portion 321 away from the second clamping portion 322 are both rotatably disposed on the support base 10. The first clamping portion 312 and the second clamping portion 322 are disposed relative to each other for clamping. The first cutting head 41 is adjustably positioned on a side of the first clamping arm 31 near the second clamping arm 32. The first cutting head 41 has a first avoidance position located on the first connecting portion 311 and a first cutting position located on the first clamping portion 312. The second cutting head 42 is adjustably positioned on a side of the second clamping arm 32 near the first clamping arm 31. The second cutting head 42 has a second avoidance position located on the second connecting portion 321 and a second cutting position located on the second clamping portion 322. When the first cutting head 41 is in the first cutting position and the second cutting head 42 is in the second cutting position, the blade of the first cutting head 41 and the blade of the second cutting head 42 are opposite each other.

[0059] With the scraper conveyor debris removal device provided in this embodiment, when it is necessary to clamp debris, the first cutter head 41 is placed in the first avoidance position and the second cutter head 42 is placed in the second avoidance position; when it is necessary to cut debris, the first cutter head 41 is placed in the first cutting position and the second cutter head 42 is placed in the second cutting position, so that the cutting of the debris is achieved by the blade portion of the first cutter head 41 and the blade portion of the second cutter head 42. At the same time, through the driving action of the clamping drive part 20, the first clamping arm 31 and the second clamping arm 32 can be moved close to each other for clamping or moved away from each other for opening. The above structure can facilitate the flexible removal of debris and is easy to operate. Therefore, the scraper conveyor debris removal device and scraper conveyor provided in this embodiment can solve the technical problem in the prior art of being inconvenient to remove debris stuck on the scraper conveyor.

[0060] Specifically, the clamping driving part 20 may be a hydraulic cylinder.

[0061] Specifically, the first cutting head 41 is rotatably disposed on the first clamping arm 31 to facilitate switching of the position of the first cutting head 41 .

[0062] Specifically, the second cutting head 42 is rotatably disposed on the second clamping arm 32 to facilitate switching of the position of the second cutting head 42 .

[0063] In this embodiment, a first slot 3121 is provided on one side of the first clamping portion 312 near the second clamping portion 322, which is compatible with at least a portion of the first blade head 41. When the first blade head 41 is in the first cutting position, at least a portion of the first blade head 41 is installed in the first slot 3121, and the blade portion of the first blade head 41 extends out of the first slot 3121. A second slot is provided on one side of the second clamping portion 322 near the first clamping portion 312, which is compatible with at least a portion of the second blade head 42. When the second blade head 42 is in the second cutting position, at least a portion of the second blade head 42 is installed in the second slot, and the blade portion of the second blade head 42 extends out of the second slot. This structural arrangement facilitates the smooth cutting of debris by the blade portions of the first blade head 41 and the blade portions of the second blade head 42, thereby improving cutting stability.

[0064] Specifically, the first clamping arm 31 further includes a first magnetic attraction member disposed at the bottom of the first clamping slot 3121, and the first cutting head 41 is made of a magnetic material. This can improve the stability of the first cutting head 41 in the first cutting position and prevent the first cutting head 41 from shaking during cutting.

[0065] Specifically, the width of the first clamping groove 3121 is larger than the diameter of the anchor rod and smaller than the maximum diameter of the nut on the anchor rod, so as to facilitate clamping of the anchor rod.

[0066] Specifically, the second clamping arm 32 further includes a second magnetic attraction member disposed at the bottom of the second clamping slot, and the second cutting head 42 is made of a magnetic material. This can improve the stability of the second cutting head 42 in the second cutting position and prevent the second cutting head 42 from shaking during cutting.

[0067] Specifically, the width of the second clamping groove is larger than the diameter of the anchor rod and smaller than the maximum diameter of the nut on the anchor rod, so as to facilitate clamping of the anchor rod.

[0068] In this embodiment, the first clamping arm 31 further includes a first stopper 313 disposed on the first connecting portion 311 and having a first engaging groove. When the first cutting head 41 is in the first avoidance position, the first cutting head 41 is retained within the first engaging groove, with the blade of the first cutting head 41 facing the bottom of the first engaging groove. This allows the first cutting head 41 to stably avoid the first clamping portion 312 when cutting is not required, remaining stably disposed on the first connecting portion 311 and preventing the blade of the first cutting head 41 from facing outward and potentially damaging other components.

[0069] In this embodiment, the second clamping arm 32 further includes a second stopper 323 disposed on the second connecting portion 321 and having a second engaging groove. When the second cutting head 42 is in the second avoidance position, the second cutting head 42 is retained within the second engaging groove, with the blade of the second cutting head 42 facing the bottom of the second engaging groove. This allows the second cutting head 42 to stably avoid the second clamping portion 322 when cutting is not required, remaining stably disposed on the second connecting portion 321 and preventing the blade of the second cutting head 42 from facing outward and potentially damaging other components.

[0070] Specifically, a first anti-slip groove 3122 and a first anti-slip groove 3123 are provided on one side of the first clamping portion 312 near the second clamping portion 322. The first anti-slip groove 3123 is located on the side of the first anti-slip groove 3122 near the first connecting portion 311. The first anti-slip groove 3123 is adapted to at least a portion of the object to be clamped, so that at least a portion of the object to be clamped is snapped into the first anti-slip groove 3123. This effectively improves the clamping stability of the object to prevent the object from loosening during the clamping process, and also improves the anti-slip capability of the clamping mechanism, making it less likely for the object to fall out between the two clamping arms during the clamping and dragging process.

[0071] Specifically, the diameter of the first anti-slip groove 3123 is larger than the maximum diameter of the anchor nut, so as to effectively clamp the anchor.

[0072] Specifically, a second anti-slip groove and a second anti-slip groove are provided on the side of the second clamping portion 322 near the first clamping portion 312. The second anti-slip groove is located on the side of the second anti-slip groove near the second connecting portion 321. The second anti-slip groove is adapted to at least a portion of the object to be clamped, so that at least a portion of the object to be clamped is snapped into the second anti-slip groove. This can help to better improve the clamping stability of the debris and prevent the debris from loosening during the clamping process.

[0073] In this embodiment, the clamping drive unit 20 is disposed between the first connecting portion 311 and the second connecting portion 321, and the driving end of the clamping drive unit 20 is arranged to be raised and lowered. The scraper conveyor debris removal device also includes a first linkage rod 51 and a second linkage rod 52. The first linkage rod 51 has two ends hingedly connected to the driving end of the clamping drive unit 20 and the first connecting portion 311, respectively. The second linkage rod 52 has two ends hingedly connected to the driving end of the clamping drive unit 20 and the second connecting portion 321, respectively. In this way, the lifting and lowering driving end of the clamping drive unit 20 can synchronously drive the first linkage rod 51 and the second linkage rod 52 to move, thereby synchronously driving the first clamping arm 31 and the second clamping arm 32 to clamp or release debris.

[0074] Specifically, the scraper conveyor debris removal device also includes a rotating frame 60 and a driving member 70. The support base 10 is rotatably disposed on the rotating frame 60 along a first rotation direction, and the rotating frame 60 is used to connect to the main body of the scraper conveyor. The main body of the driving member 70 is hinged to the rotating frame 60, and the driving end of the driving member 70 is hinged to the support base 10, and the driving end of the driving member 70 is retractably disposed. In this way, the support base 10 can be rotated in the first rotation direction to increase the range of motion of the first clamping arm 31 and the second clamping arm 32, facilitate adjustment of the clamping and dragging direction of the device, reduce resistance when debris is pulled out, make it easier to pull out debris, and also facilitate adjustment of the deflection angle in the first rotation direction.

[0075] Specifically, the driving member 70 may be a hydraulic cylinder.

[0076] In this embodiment, the scraper conveyor debris removal device also includes: a hanger 80 and a drive worm 90, which are fixedly connected to the main body of the scraper conveyor, and the rotating frame 60 is rotatably arranged on the hanger 80 along the second rotation direction, and the rotating frame 60 is provided with a vortex 61; the drive worm 90 is rotatably arranged on the hanger 80, and the drive worm 90 cooperates with the vortex 61 (specifically meshes) so that the drive worm 90 drives the rotating frame 60 to rotate through the vortex 61. In this way, the structure is simple and the rotation is stable. In addition, the range of motion of the first clamping arm 31 and the second clamping arm 32 is also improved, which facilitates the adjustment of the deflection angle in the second rotation direction. When the worm has an arc greater than half of the circumference, the rotating frame 60 can be laid flat, and the device can be folded at the top of the bracket, which can effectively avoid the comprehensive mining machine and passing personnel.

[0077] Specifically, the driving worm 90 is driven by the hydraulic motor 100 .

[0078] Specifically, the first rotation direction may be a front-to-back rotation, and the second rotation direction may be a left-to-right rotation. The rotation axis corresponding to the first rotation direction is perpendicular to the rotation axis corresponding to the second rotation direction.

[0079] The scraper conveyor debris removal device of this embodiment further includes a telescopic drive structure 110, which is disposed between the rotating frame 60 and the support base 10. The telescopic drive structure 110 may also be a hydraulic cylinder. The telescopic drive structure 110 is extended or retracted to move debris closer to or further away from the scraper conveyor, or to move debris onto the scraper conveyor or remove the debris from the scraper conveyor.

[0080] When the scraper conveyor debris removal device provided by this embodiment is used, when encountering debris that needs to be cut (mainly referring to long and heavy stick-shaped or plate-shaped objects), the limit of the first blade head 41 and the second blade head 42 is released, and the first blade head 41 and the second blade head 42 are rotated so that the first blade head 41 is in the first cutting position and the second blade head 42 is in the second cutting position. When the clamping drive part 20 is shortened, the opening of the first clamping arm 31 and the second clamping arm 32 is narrowed, and the debris is clamped, the first blade head 41 and the second blade head 42 located in the clamping part contact the debris before the clamping part, and then cut off the debris. Then, the first blade head 41 and the second blade head 42 are flipped up and connected and fixed in the first avoidance position and the second avoidance position respectively. After the large debris is cut off, the small debris is light in weight, more suitable for transportation, and more convenient to clean. After that, the device can be used normally.

[0081] By setting up a hoisting-mounted rotating frame 60, a driving member 70, a hanger 80, a hydraulic motor 100, and a telescopic driving structure 110, debris stuck on the scraper conveyor can be removed, making it more convenient and labor-saving to use. By setting up a rotatable first cutter head 41 and a rotatable second cutter head 42, the device can be used as a shearing tool, which is convenient for cutting large debris and facilitating transportation.

[0082] When the scraper conveyor transports debris to a position not directly below the hanger 80, the debris is at a certain distance from the device, and the insertion direction of the debris (mainly stick-shaped anchor rods and the like) is aligned with the clamping mechanism. The bottom ends of the first clamping arm 31 and the second clamping arm 32 are bent to point in the direction of the debris, and then the debris is removed so that the debris can be removed in the opposite direction along the insertion direction of the stuck part, thereby making it easier for the debris to be removed from the scraper conveyor, with less resistance and less likely to break when the debris is taken out.

[0083] By providing the hanger 80 and the rotating frame 60 , the device can cover a larger range, facilitate adjustment of the clamping and dragging direction of the device, reduce the resistance when the debris is pulled out, and make it easier to pull the debris out.

[0084] When encountering a long and heavy stick or plate-like object that needs to be cut, the first clamping arm 31 and the second clamping arm 32 are opened, the limit of the first blade head 41 and the second blade head 42 is released, and the first blade head 41 and the second blade head 42 are rotated so that they are respectively in the first cutting position and the second cutting position and are attracted by the magnetic adsorption member (which can be a magnetic block), so that the first blade head 41 and the second blade head 42 are fixed, and the blade portion of the first blade head 41 is higher than the top of the first slot 3121 by a certain height. When the clamping drive part 20 is shortened, the opening of the two first clamping arms 31 and the second clamping arms 32 is reduced, and the first blade head 41 and the second blade head 42 contact the debris before the first clamping arm 31 and the second clamping arm 32, and then cut the debris. Then, the first blade head 41 and the second blade head 42 are flipped up and respectively connected and fixed to the first limit member 313 and the second limit member 323. After the large debris is cut off, the small debris is light in weight, more suitable for transportation, and more convenient to clean. After that, the device can be used normally.

[0085] Another embodiment of the present invention provides a scraper conveyor, which includes a main body and the above-mentioned scraper conveyor debris removal device, wherein the scraper conveyor debris removal device is arranged on the main body.

[0086] From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: it can remove debris stuck on the scraper conveyor, and it is more convenient and labor-saving to use. By installing a rotatable cutter head on the clamping frame, the device can be used as a shearing tool, which is convenient for cutting large debris and facilitating transportation.
