Description

Technical Field

[0001] This invention belongs to the field of coal crushing technology, and particularly relates to a scraper conveyor with a crushing device in a fully mechanized longwall mining face. Background Technology

[0002] Scraper conveyors are used in coal mines to transport coal lumps, employing scraper chains for traction. During fully mechanized longwall mining, large coal lumps are easily generated. These lumps increase the transport resistance of the scraper chain, leading to increased motor load. Prolonged overload operation can cause chain fatigue or even breakage. Traditional scraper conveyors primarily function as transport systems, but large coal lumps can easily clog unloading points (such as the intersection of the conveyor head and the transfer conveyor), causing coal accumulation, equipment downtime, and even equipment damage or safety accidents.

[0003] Patent application number 202311703385.3 discloses a scraper conveyor with a pre-crushing device. This invention discloses a scraper conveyor with a pre-crushing device, including a conveyor body, a first pre-crushing device, and a second pre-crushing device. The conveyor body includes a horizontal base plate and an inclined base plate, with several scrapers driven by chains on the horizontal and inclined base plates. The first and second pre-crushing devices are positioned above the horizontal base plate. The first pre-crushing device includes a rotatable mounting base with a crushing column that cooperates with coal blocks on the horizontal base plate. The second pre-crushing device includes a vertically arranged crushing roller. The lowest point of the crushing roller is higher than the highest point of the scraper. However, this device only uses an impact hammer to crush large coal blocks one by one, making it impossible to control the size of the crushed coal blocks, resulting in excessively large differences in coal block size. This invention proposes a structure capable of uniformly crushing large coal blocks. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a scraper conveyor with a crushing device for fully mechanized mining faces, thus solving the aforementioned problems.

[0014] Beneficial effects

[0015] This invention provides a scraper conveyor with a crushing device for fully mechanized mining faces, which has the following advantages compared with the prior art:

[0016] 1. When the coal block is on plate B, plate A simultaneously moves towards plate B, contacting the coal block through its inserted tubes A and B, pressing the coal block onto the guide plate. During this process, plate A continues to slide towards the coal block, causing inserted tubes A and B to gradually penetrate into the coal block. After inserted tubes A and B have penetrated to a certain depth, two cams A simultaneously engage with cam B. Since the contact surfaces of cams B and A are both curved, as plate A continues to move towards plate B, the two cams A begin to slide to both sides under the action of cam B, meaning the distance between the two connecting plates gradually increases. This causes the inserted tubes B, which have penetrated the coal block, to begin to separate, thus applying a pushing force to the coal block internally, allowing it to evenly split into several smaller coal blocks on both sides. When the smaller coal blocks... When a coal block falls onto the guide plate, if the volume of the coal block is smaller than the distance between the two guide plates, it means that the coal block meets the crushing standard, allowing it to fall onto the scraper conveyor for continued transport. At this time, the coal block still on plate B continues to slide downwards until it comes into contact with the next set of insertion tubes A and B on plate A, thereby splitting the coal block into several smaller coal blocks, which then fall onto the scraper conveyor for transport. Since plate A is equipped with multiple sets of insertion tubes A and B, the coal block can be cyclically crushed and split into several coal blocks of similar size. At the same time, for coal blocks that still do not meet the size requirements, since plate A is inclined on plate B, they can be stuck in the corresponding position during the sliding process, so that when the larger coal blocks are crushed, they are simultaneously crushed a second time.

[0017] 2. When the coal block is on plate B, the user can start the motor, causing the gear fixedly connected to the motor output shaft to start rotating at a constant speed. This drives the gear ring meshed with the gear ring to start rotating synchronously. At this time, plate A, which is fixedly connected eccentrically between the two gear rings, begins to rotate. Simultaneously, since the other side of plate A is rotatably connected to plate B via a connecting rod, plate A begins to periodically move closer to plate B. Thus, when the coal block rolls along the inclined surface of plate B, plate A can limit its movement, preventing it from continuing to roll. It also applies a thrust to insertion tubes A and B, allowing them to be inserted. The coal block is crushed by plate A periodically moving towards plate B, thus achieving cyclical splitting of the coal block. Simultaneously, when the two connecting plates slide towards each other, they can drive the fixed connecting plates on them to slide synchronously, causing the two connecting plates to pull the spring fixed between them, putting the spring into a deformed state. When the two cams A disengage from cam B, the spring can pull the insertion tubes A and B back to the contact state, so that after the insertion tubes A and B disengage from the coal block, they can quickly reset, so as to repeat the splitting of the coal block.

[0018] 3. When large pieces of coal are transported on the scraper conveyor, and their volume meets the preset conditions of the identification probe, the cylinder is activated, pushing the two positioning discs closer together until both ends of the coal block are between positioning rod B and positioning rod A. This initially limits the movement of the coal block, preventing it from being further transported by the scraper conveyor. The user then starts motor B, causing the guide rod fixedly connected to its output shaft to rotate. This, in turn, causes the guide rod to rotate the guide gear connected to its other end, in a circular motion. The guide gear then rolls on gear ring A, adjusting the position of its corresponding positioning rod A. When motor B starts, pulley A, which is fixedly connected to its output shaft, rotates synchronously. In conjunction with the belt connected to its drive, pulley A begins to rotate synchronously with pulley B, causing the guide gear fixedly connected to it to roll on gear ring A. At this time, the two guide gears begin to move towards each other, causing the two positioning rods A to engage and contact the bottom of the coal block. The two plates A then support the coal block at the bottom, preventing it from falling when transferred to plate B. The user can then start motor A, allowing the coal block fixed between the two positioning plates to be transferred to plate B, thus beginning the splitting of the coal block.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0029] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0030] Please see Figure 1 as well as Figure 2According to one embodiment of the present invention, a scraper conveyor with a crushing device for a fully mechanized mining face includes a scraper conveyor 101, and further includes: plate B201, plate A202, and connecting plate 205. Plate B201 is obliquely and fixedly connected to the scraper conveyor 101. Plate A202 is obliquely disposed above plate B201, and there is a certain distance between plate A202 and plate B201. Plate A202 is provided with multiple sets of insert tubes A203 and insert tubes B204. Two adjacent insert tubes A203 and insert tubes B204 are joined together to form a cone. Insert tubes A203 and insert tubes B204 are respectively fixedly connected to the connecting plate 205. Multiple connecting plates 205 are slidably connected to plate A202. The connecting plate 205 is provided with a driving component for driving insert tubes A203 and insert tubes B204 to slide towards each other.

[0031] It also includes a screening assembly for causing the crushed coal blocks to fall onto the scraper conveyor 101; and a pressurizing assembly 3 for driving plate A202 to reciprocate toward plate B201.

[0032] Please see Figure 4 Specifically, the drive assembly includes cam A206 and cam B207. The two cams A206 are fixedly connected to two adjacent connecting plates 205 respectively. The cam B207 is located below the two cams A206. The multiple cams B207 are all fixedly connected to plate B201 at an inclination, and the inclination of the multiple cams B207 is the same as that of plate A202.

[0033] Please see Figure 8 Specifically, the screening component includes connecting rods 209, multiple connecting rods 209 are fixedly connected to the frame of plate B201, and two guide plates 208 are provided above each of the multiple connecting rods 209. The multiple guide plates 208 are fixedly connected to plate B201, and the spacing between the multiple guide plates 208 is the same.

[0034] In this embodiment of the invention, when the coal block is on plate B201, plate A202 simultaneously moves closer to plate B201 and contacts the coal block through the insertion tubes A203 and B204, pressing the coal block onto guide plate 208. During this process, plate A202 continues to slide towards the coal block, causing insertion tubes A203 and B204 to gradually penetrate into the coal block. After insertion tubes A203 and B204 penetrate to a certain depth, two cams A206 simultaneously engage with cam B207. Since the contact surfaces of cam B207 and cam A206 are both arc surfaces, as plate A202 continues to move closer to plate B201, the two cams A206 begin to slide to both sides under the action of cam B207, that is, the distance between the two connecting plates 205 gradually increases, causing the insertion tubes B204 inserted into the coal block to begin to separate, thereby applying a pushing force to the coal block from the inside, allowing it to be evenly split into several parts on both sides. Smaller coal blocks, when they fall onto guide plates 208, if their volume is less than the distance between the two guide plates 208, indicate that they meet the crushing standard and can fall onto scraper conveyor 101 for further transport. Coal blocks still on plate B201 continue to slide downwards until they come into contact with the next set of insertion tubes A203 and B204 on plate A202, thus splitting the coal block into several smaller coal blocks, which then fall onto scraper conveyor 101 for transport. Since plate A202 is equipped with multiple sets of insertion tubes A203 and B204, the coal block can be cyclically crushed and split into several coal blocks of similar size. At the same time, for coal blocks that still do not meet the size requirements, since plate A202 is inclined on plate B201, they can be stuck in the corresponding position during the sliding process, thus simultaneously crushing the larger coal blocks.

[0035] Please see Figure 3 as well as Figure 8 Specifically, the pressurizing assembly 3 includes a connecting rod 301, a shaft disk 302, and a gear ring 303. One end of each connecting rod 301 is hinged to a plate B201, and the other end of each connecting rod 301 is hinged to one side of a plate A202. The other side of the plate A202 is rotatably connected to the shaft disk 302, and the connection point between the plate A202 and the shaft disk 302 is located at the eccentric part of the shaft disk 302. Two shaft disks 302 are rotatably connected to the plate B201.

[0036] It also includes a transmission assembly for driving the shaft disk 302 to rotate cyclically.

[0037] Please see Figure 8 as well as Figure 3Specifically, the transmission assembly includes a gear ring 303, a gear 304, and a motor 305. The two gear rings 303 are respectively fixedly connected to the shaft disk 302. The gear 304 meshes with the gear ring 303 and is fixedly connected to the output shaft of the motor 305. The motor 305 is fixedly connected to the plate B201.

[0038] Please see Figure 4 Specifically, each of the two connecting plates 205 is fixedly connected to a connecting plate 306, and multiple connecting plates 306 are slidably connected to the guide rod 308. The two guide rods 308 are symmetrically fixedly connected to both sides of the plate A202. A spring 307 is fixedly connected between the connecting plates 306, and the spring 307 is sleeved on the guide rod 308.

[0039] In this embodiment of the invention, when the coal block is on plate B201, the user can start the motor 305, causing the gear 304 fixedly connected to the output shaft of the motor 305 to start rotating at a constant speed, and driving the gear ring 303 meshing with it to start rotating synchronously. At this time, the plate A202 fixedly connected at the eccentric point between the two gear rings 303 begins to rotate. At the same time, since the other side of plate A202 is rotatably connected to plate B201 through connecting rod 301, plate A202 begins to periodically abut against plate B201. Thus, when the coal block rolls along the inclined surface of plate B201, plate A202 can limit its movement, preventing it from continuing to roll, and can apply a thrust to the insertion tube A203 and insertion tube B204. This allows the plate to be inserted into the coal block for crushing. The plate A202 periodically moves against the plate B201, thus achieving the cyclical splitting of the coal block. Simultaneously, when the two connecting plates 205 slide towards each other, they can drive the connecting plate 306 fixedly connected to them to slide synchronously. This causes the two connecting plates 306 to start pulling the spring 307 fixed between them, putting the spring 307 into a deformed state. When the two cams A206 disengage from the cam B207, the spring 307 can pull the insertion tubes A203 and B204 back to the adhering state. Thus, after the insertion tubes A203 and B204 disengage from the coal block, they can quickly reset, so as to repeat the splitting of the coal block.

[0040] Please see Figure 6 as well as Figure 7Specifically, the transfer assembly 4 includes a positioning disk 401, a positioning rod A402, and a positioning rod B403. The two positioning disks 401 are symmetrically arranged on both sides of the scraper conveyor 101. The positioning rod A402 is fixedly connected to the positioning disk 401. The two positioning rods B403 are located below the positioning rod A402 and are slidably arranged in the arc-shaped groove of the positioning disk 401. The two positioning disks 401 are respectively fixedly connected to the piston rod of the cylinder 4005. The cylinder 4005 is fixedly connected to the bracket 4002.

[0041] And an adjustment component for adjusting the distance between the two positioning rods B403.

[0042] Please see Figure 6 as well as Figure 7 Specifically, the adjustment assembly includes guide gears 404 and gear rings A405. Two guide gears 404 are rotatably connected to their corresponding positioning rods B403, and both guide gears 404 are meshed with the gear rings A405. The gear rings A405 are fixedly connected to the positioning disk 401. A guide rod 406 is rotatably connected to each guide gear 404, and the other end of the guide rod 406 is fixedly connected to the output shaft of the motor B407. A pulley B4001 is fixedly connected to the guide gear 404, and a belt 409 is drivenly connected to the pulley B4001. The other end of the belt 409 is drivenly connected to the pulley A408. The pulley A408 is fixedly connected to the output shaft of the motor B407, and the motor B407 is fixedly connected to the center of the positioning disk 401. Identification probes 4004 are symmetrically fixedly connected to both sides of the scraper conveyor 101. The identification probes 4004 are electrically connected to the cylinder 4005.

[0043] In this embodiment of the invention, when a large piece of coal is transported on the scraper conveyor 101, and its volume meets the preset conditions of the identification probe 4004, the cylinder 4005 is activated, thereby pushing the two positioning discs 401 closer together until both ends of the coal block are between the positioning rods B403 and A402, thus initially limiting the coal block and preventing it from being transported by the scraper conveyor. Subsequently, the user starts the motor B407, which drives the guide rod 406 fixedly connected to its output shaft to start rotating. This causes the guide rod 406 to drive the guide gear 404, which is rotatably connected to its other end, to begin circular motion. At this time, the guide gear 404 begins to roll on the gear ring A405, thereby adjusting the corresponding positioning rod. At position A402, when motor B407 starts, pulley A408 fixedly connected to its output shaft rotates synchronously, and with the cooperation of belt 409 connected to it, it begins to rotate synchronously with pulley B4001, causing guide gear 404 fixedly connected to it to start rolling on gear ring A405. At this time, the two guide gears 404 begin to move towards each other, causing the two positioning rods A402 to cooperate and contact the bottom of the coal block. At this time, the two plates A202 support the coal block at the bottom, thus preventing the coal block from falling when it is transferred to plate B201. Then the user can start motor A4003, so that the coal block fixed between the two positioning plates 401 is transferred to plate B201, thus starting the splitting of the coal block.

[0044] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0045] The term "fixed connection" as used in this application refers to a connection in which parts or components are fixed without any relative movement. This includes both detachable and non-detachable connections.

[0046] (1) Detachable connection: The components are fixed together using screws, splines, wedges, etc. This type of connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of the bolts, keys, wedges) and properly tightened.

[0047] (2) Non-removable connections: These mainly refer to welding, riveting, and tenon joints. Since disassembly requires forging, sawing, or oxyacetylene cutting for repair or replacement, the parts generally cannot be reused. At the same time, attention should be paid to process quality, technical inspection, and remedial measures (such as correction, etc.) during connection.

[0048] The sliding connection referred to in this application means that the component can slide along a linear trajectory, and the hinge referred to in this application means that the component can rotate along an axial constraint.

[0049] In some cases, the sliding connection and hinge referred to in this application may also be damped, enabling the component to maintain in the desired position.
