Description

Technical Field

[0001] This utility model relates to the technical field of mining conveying equipment, specifically a large-angle corrugated sidewall conveying device for coal mines. Background Technology

[0002] As my country's main energy source, the efficiency and reliability of coal mining and transportation are of paramount importance. In underground and surface production systems of coal mines, belt conveyors are key equipment for coal transfer, especially in situations where space is limited or steep-angle lifting is required, which places higher demands on the performance of conveying equipment.

[0003] Currently, conveyor belts with corrugated sidewalls and diaphragms are gradually being used in the coal mining industry to achieve steep-angle conveying. However, these existing devices still have significant drawbacks in practical applications. First, due to the uneven size of the conveyed coal (large, medium, and small pieces), existing corrugated sidewall conveyor belts typically use a single conveying chamber structure. During operation, especially under vibration and impact, small pieces and broken coal are easily spilled from the gaps between the top of the sidewall and the diaphragm, causing not only material loss and cleaning burden but also safety hazards. Second, the existing sidewall structure lacks a targeted layered guidance design, making it difficult to effectively collect and gather the spilled small pieces of coal, leading to accumulated problems. In addition, during the conveying process, especially at the material drop point, a large amount of dust is generated, and the sealing and dust prevention measures of existing devices are often inadequate, making it difficult to effectively suppress the spread of coal dust, seriously polluting the working environment and endangering personnel health.

[0004] Therefore, there is an urgent need for a large-angle corrugated sidewall conveyor optimized for the harsh working conditions of coal mines. It can effectively solve the problem of small material spillage and splashing, and effectively control dust, thereby improving the reliability, environmental protection and overall efficiency of the conveying process. Utility Model Content

[0005] The purpose of this invention is to provide a large-angle corrugated sidewall conveyor for coal mines, which has the advantages of good sealing, anti-spillage, high dust suppression efficiency and stable operation, and solves the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A large-angle corrugated sidewall conveyor for coal mines includes a frame, a conveyor fixed to the frame, a collection box fixed to the frame, a discharge cylinder fixed to the lower end of the collection box, a material blocking mechanism set at the upper end of the frame, a material pushing mechanism fixed at the upper end of the frame, a material feeding mechanism set at the upper end of the frame, and an auxiliary feeding mechanism set in the discharge cylinder.

[0008] The pushing mechanism is used to push small pieces of coal that have fallen onto the feeding mechanism into the conveyor belt and collection mechanism of the conveyor.

[0009] Dustproof mechanisms are installed on both sides of the feeding mechanism.

[0010] Preferably, the material blocking mechanism includes two first support blocks fixed to the upper end of the frame, a bearing seat fixed to the upper end of each first support block, a first rotating rod rotatably mounted on the inner wall of the two bearing seats, and two baffles fixed to the side wall of the first rotating rod.

[0011] It is worth noting that this material blocking mechanism, through the rotational cooperation between the bearing seat and the first rotating rod, can prevent excessively high coal ore on the conveyor belt from being leveled off, and the two baffles can improve the stability of the first rotating rod.

[0012] Preferably, the pushing mechanism includes a vertical block fixed to the upper end of the frame, a first cylinder fixed to the vertical block, a first push block fixed to the output shaft of the first cylinder, two upper connecting rods fixed to the upper part of the first push block away from the vertical block, a first push plate fixed to the upper connecting rod away from the vertical block, two lower connecting rods fixed to the lower part of the first push block away from the vertical block, and a second push plate fixed to the lower connecting rod away from the vertical block.

[0013] It is worth noting that this pushing mechanism uses a first cylinder to drive the first pushing block. Through the connecting rods and pushing plate arranged in upper and lower layers, it can push small pieces of coal at different positions on the feeding mechanism in layers, which can avoid material accumulation. The pushing stroke is precisely controlled by the cylinder to adapt to the pushing needs of different material amounts. The pushing plate has a large contact area with the material, resulting in a good pushing effect, reducing material residue, and improving the continuity of feeding.

[0014] Preferably, the feeding mechanism includes a second support block fixed to both sides of the frame, an inclined plate fixed to the upper end of the second support block, a support plate fixed to the upper end of the inclined plate, a support base fixed to the upper end of the support plate, a fixed frame fixed to the upper end of the two supports, a feed hopper fixed to the upper end of the fixed frame, two guide plates fixed to the lower end of the fixed frame, a plurality of first grooves opened through the lower end of the guide plates, two fixed blocks fixed to the upper end of the frame, a conveying frame fixed to the upper end of the fixed blocks, and a groove opened at the upper end of the fixed blocks. The upper end of the conveying frame passes through a corrugated baffle and extends into the groove. The lower end of the conveying frame extends above the collecting mechanism. The support plate is inverted U-shaped. The lower end of the feed hopper is open. The groove is set opposite to the first push plate. The concave surface of the lower half of the corrugated baffle is set opposite to the second push plate.

[0015] It is worth noting that this feeding mechanism uses inclined plates to initially guide the material, and the inverted U-shaped support plate ensures the structural support strength without obstructing the material passage. The first groove on the guide plate can evenly distribute the material to avoid blockage caused by concentrated feeding. The cooperation between the conveying frame and the groove allows the material to fall accurately into the collection mechanism, and the design of the lower end of the feed hopper opening ensures smooth feeding.

[0016] Preferably, the collection mechanism includes a temporary storage box fixed to the upper end of the second support block, a second cylinder fixed to one side of the temporary storage box, and a second push block fixed to the output shaft of the second cylinder. The lower end of the second push block is in contact with the bottom surface of the inner wall of the temporary storage box, and the lower end of the material conveying frame is located above the temporary storage box.

[0017] It is worth noting that this collection mechanism uses a temporary storage box to temporarily store small pieces of coal, avoiding direct accumulation of materials that could affect the operation of the conveyor. The lower end of the second pusher block fits against the bottom of the temporary storage box, ensuring thorough material pushing without residue. The second cylinder drives the pusher block to move precisely, adjusting the pushing frequency in accordance with the conveyor's rhythm. The lower end of the material conveying frame aligns with the temporary storage box to ensure accurate material dropping. The overall structure achieves centralized collection and orderly pushing of materials, improving collection efficiency.

[0018] Preferably, a feeding trough is provided through the lower end of the collection box, and the auxiliary feeding mechanism includes support blocks fixed to the upper and lower parts of the inner wall of the discharge cylinder, a second rotating rod rotatably installed on the inner wall of the two support blocks, and an auger fixed to the side wall of the second rotating rod.

[0019] It is worth noting that this auxiliary feeding mechanism provides stable support for the second rotating rod through support blocks. The auger structure is adapted to the conveying characteristics of coal and mineral materials, which can effectively avoid blockage caused by the accumulation of materials due to gravity in the discharge cylinder. The chute and auger work together to achieve continuous discharge, especially at the discharge end of the large-angle conveying, which can ensure the continuity of material conveying and reduce jamming.

[0020] Preferably, the dustproof mechanism includes dustproof blocks fixed to both sides of the fixed frame and dustproof sponge fixed to one end of the dustproof blocks near the center of the fixed frame.

[0021] It is worth noting that this dustproof mechanism uses dustproof blocks to fix the dustproof sponge. The dustproof sponge fits into the material passage area on both sides of the fixed frame, which can effectively block the dust generated during the feeding process from escaping and reduce dust pollution in the working environment. The dustproof sponge is made of soft and breathable material, which does not affect the normal passage of materials, and also has a certain degree of wear resistance.

[0022] Preferably, the dustproof mechanism includes multiple baffles fixed to the bottom surface of the inner wall of the fixed frame and multiple curtains fixed to both sides of the fixed frame, the curtains and baffles forming a closed structure.

[0023] It is worth noting that this dust control mechanism forms a closed structure with baffles and curtains, which can effectively contain the feeding area and greatly reduce dust diffusion. The baffles can support the curtain to prevent it from deforming due to material impact. The curtain is made of flexible material, which does not affect the smoothness of material feeding. The overall structure is stable, the dust control effect is significant, it is suitable for the high dust working conditions in coal mines, and it is easy to maintain.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0025] 1. By combining a rotatable baffle mechanism with a feeding mechanism that has a graded flow guiding function, the problem of small pieces of material spilling is effectively solved. The baffle plate of the baffle mechanism rotates adaptively with the operation of the conveyor belt, which can block excessively high coal pieces on the conveyor belt and smooth them out, ensuring the stability of material conveying. At the same time, the two baffle plates improve the stability of the first rotating rod. The guide plate of the feeding mechanism has a first trough to realize automatic material grading. Large pieces of material directly enter the conveyor belt, while small pieces of material fall into the conveying frame through the trough. At the same time, the pushing mechanism actively cleans up the stagnant material by driving the push plate with a cylinder, and accurately pushes the small pieces of coal pieces to the conveyor belt or the collection mechanism, realizing the diversion and secondary collection of materials, fundamentally eliminating the hidden danger of materials spilling from the gaps of the baffle.

[0026] 2. The multi-layered dustproof design significantly improves the dust suppression effect. The feeding mechanism adopts a fixed frame and a guide plate to form a relatively closed material drop channel, which suppresses dust generation from the source. The dustproof mechanism is equipped with a combination of dustproof sponge or curtain baffle column on both sides of the feeding point to form a flexible sealing barrier, which effectively blocks the dust diffusion path. This three-dimensional dustproof system greatly reduces the dust emission at the material drop point, improves the working environment, and protects the health and safety of operators.

[0027] 3. The coordinated operation of the collection mechanism and the auxiliary feeding mechanism ensures the continuous stability of the system. The temporary storage box of the collection mechanism, together with the cylinder pusher, realizes the temporary storage and timed discharge of spilled materials. The auger of the auxiliary feeding mechanism rotates and conveys materials in the discharge cylinder to prevent material blockage at the discharge chute of the collection box. The coordinated cooperation of various actuators forms a complete closed-loop system for material collection, temporary storage and output, which significantly improves the reliability and conveying efficiency of the equipment under harsh working conditions.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] To address the problems in existing technologies, such as the easy spillage of small pieces and broken coal from the gaps between the retaining walls and transverse partitions, the lack of a stratified collection structure for spilled materials, and severe dust dispersion at the material drop point, the following technical solution is proposed. Please refer to [link / reference needed]. Figures 1-8 ;

[0039] A large-angle corrugated sidewall conveyor for coal mines includes a frame 1, a conveyor 2 fixed to the frame 1, a collection box 3 fixed to the frame 1, a discharge cylinder 4 fixed to the lower end of the collection box 3, a material blocking mechanism set at the upper end of the frame 1, a material pushing mechanism fixed at the upper end of the frame 1, a material feeding mechanism set at the upper end of the frame 1, and an auxiliary feeding mechanism set in the discharge cylinder 4.

[0040] The pushing mechanism is used to push small pieces of coal that have fallen onto the feeding mechanism into the conveyor belt and collection mechanism of the conveyor 2;

[0041] Dustproof mechanisms are installed on both sides of the feeding mechanism.

[0042] When in use, the coal is poured into the feeding mechanism. The pushing mechanism can push the small pieces of coal that fall on the feeding mechanism into the conveyor belt and collection mechanism of the conveyor 2. The collection mechanism can push the coal into the collection box 3. The small pieces of coal can be output downward through the auxiliary feeding mechanism.

[0043] In this embodiment, specifically: the material blocking mechanism includes two first support blocks 201 fixed to the upper end of the frame 1, a bearing seat 202 fixed to the upper end of each first support block 201, a first rotating rod 203 rotatably mounted on the inner wall of the two bearing seats 202, and two baffles 204 fixed to the side wall of the first rotating rod 203.

[0044] In this embodiment, specifically: the pushing mechanism includes a vertical block 5 fixed to the upper end of the frame 1, a first cylinder 6 fixed to the vertical block 5, a first push block 7 fixed to the output shaft of the first cylinder 6, two upper connecting rods 8 fixed to the upper part of the first push block 7 away from the vertical block 5, a first push plate 9 fixed to the upper connecting rod 8 away from the vertical block 5, two lower connecting rods 10 fixed to the lower part of the first push block 7 away from the vertical block 5, and a second push plate 11 fixed to the lower connecting rod 10 away from the vertical block 5.

[0045] In this embodiment, specifically: the feeding mechanism includes second support blocks 12 fixed to both sides of the frame 1, an inclined plate 13 fixed to the upper end of the second support blocks 12, a support plate 14 fixed to the upper end of the inclined plate 13, a support base 15 fixed to the upper end of the support plate 14, a fixed frame 16 fixed to the upper end of the two supports 15, a feed hopper 17 fixed to the upper end of the fixed frame 16, two guide plates 18 fixed to the lower end of the fixed frame 16, and a plurality of first grooves 1 through the lower end of the guide plates 18. 9. Two fixed blocks 20 fixed to the upper end of the frame 1, a conveying frame 21 fixed to the upper end of the fixed block 20, and a groove 23 opened on the upper end of the fixed block 20. The upper end of the conveying frame 21 passes through the corrugated baffle 22 and extends into the groove 23. The lower end of the conveying frame 21 extends to the top of the collecting mechanism. The support plate 14 is inverted U-shaped. The lower end of the feed hopper 17 is open. The groove 23 is set opposite to the first push plate 9. The concave surface of the lower half of the corrugated baffle 22 is set opposite to the second push plate 11.

[0046] In this embodiment, specifically: the collection mechanism includes a temporary storage box 24 fixed to the upper end of the second support block 12, a second cylinder 25 fixed to one side of the temporary storage box 24, and a second push block 26 fixed to the output shaft of the second cylinder 25. The lower end of the second push block 26 is in contact with the bottom surface of the inner wall of the temporary storage box 24, and the lower end of the material conveying frame 21 is located above the temporary storage box 24.

[0047] In this embodiment, specifically: a feeding trough 27 is provided through the lower end of the collection box 3, and the auxiliary feeding mechanism includes support blocks 28 fixed to the upper and lower parts of the inner wall of the discharge cylinder 4, a second rotating rod 29 rotatably installed on the inner wall of the two support blocks 28, and an auger 30 fixed to the side wall of the second rotating rod 29.

[0048] Example 1: In this example, the dustproof mechanism includes dustproof blocks 31 fixed to both sides of the fixed frame 16 and dustproof sponge 32 fixed to one end of the dustproof blocks 31 near the center of the fixed frame 16. The dustproof blocks 31 on both sides of the fixed frame 16 provide a stable installation support for the dustproof sponge 32, ensuring that the dustproof structure is not easy to loosen or shift. The dustproof sponge 32 is soft and has good sealing properties, which can accurately fit the gaps on both sides of the feeding area, effectively blocking the coal dust generated during coal mine feeding, reducing dust pollution to the surrounding environment, and preventing operators from inhaling dust and harming their health.

[0049] Example 2: In this example, specifically: the dust prevention mechanism includes multiple baffles 33 fixed to the bottom surface of the inner wall of the fixed frame 16 and multiple curtains 34 fixed to both sides of the fixed frame 16. The curtains 34 and the baffles 33 form a closed structure. The multiple baffles 33 on the bottom surface of the inner wall of the fixed frame 16 can slow down the falling speed of the coal and prevent the coal from violently impacting the inner wall of the feeding mechanism, thus reducing dust generation from the source. The multiple curtains 34 on both sides of the fixed frame 16 and the baffles 33 form a fully enclosed structure, which can block the dust diffusion path in all directions, with a wider dust prevention coverage and a more thorough sealing effect. The curtains 34 have flexible characteristics and can naturally avoid the falling coal, which does not affect the feeding efficiency and can continuously block the dust from overflowing, adapting to the feeding needs of coal with different particle sizes.

[0050] Working principle: When in use, first start the conveyor 2 and put the coal and mineral materials to be conveyed into the feed hopper 17. The material falls onto the guide plate 18 in the fixed frame 16. Large pieces of material are guided by the guide plate 18 and slide directly into the corrugated sidewall conveyor belt bearing surface of the conveyor 2, while small pieces and broken coal fall into the conveying frame 21 below through the multiple first troughs 19 opened on the guide plate 18.

[0051] At this time, the first cylinder 6 fixed to the vertical block 5 is activated. The output shaft of the first cylinder 6 drives the first push block 7 and its upper connecting rod 8 fixed to the upper part and the first push plate 9, and the lower connecting rod 10 fixed to the lower part and the second push plate 11 to move synchronously. The first push plate 9 and the second push plate 11 act on the upper surface of the guide plate 18 and the inlet area of ​​the conveying frame 21 respectively, pushing the small pieces of coal that are stuck into the conveyor belt of the conveyor 2 or into the temporary storage box 24 through the conveying frame 21.

[0052] The first rotating rod 203, which is rotatably installed in the bearing seat 202 fixed to the upper end of the first support block 201, and the two baffles 204 fixed to its side wall can rotate around the axis of the first rotating rod 203. When coal and mineral materials that are piled up too high pass through the conveyor belt of the conveyor 2, the baffles 204 are pushed by the material and rotate, blocking and smoothing the excessively high material, preventing it from piling up too high and causing spillage or jamming. At the same time, the setting of the two baffles 204 enhances the structural stability of the first rotating rod 203 when under force.

[0053] Small pieces of material falling into the temporary storage box 24 are pushed into the collection box 3 by the second pusher block 26 driven by the second cylinder 25 fixed to one side of the temporary storage box 24.

[0054] The material in the collection box 3 enters the discharge cylinder 4 through the discharge chute 27 that is opened through its lower end. The second rotating rod 29, which is fixed to the support block 28 on the inner wall of the discharge cylinder 4, drives the auger 30 to rotate, so as to achieve the forced and smooth discharge of the material.

[0055] Throughout the feeding and conveying process, the dustproof blocks 31 and dustproof sponges 32 fixed to both sides of the fixed frame 16, or the closed structure consisting of multiple baffles 33 fixed to the bottom of the inner wall of the fixed frame 16 and multiple curtains 34 fixed to both sides of the fixed frame 16, can effectively suppress the spread of coal dust and ensure a clean working environment.
