Description

Technical Field

[0001] This invention relates to the field of conveying device technology, and specifically to a continuous coal mine tilting conveyor. Background Technology

[0002] Coal mines are important energy resources, widely used in power, metallurgy, chemical and other fields. After mining, coal needs to undergo a series of processing steps before it can be put into use, and transportation is an indispensable link in this process. To achieve efficient coal transportation, various transportation devices have emerged. Among them, conveyor belt-based transportation equipment is widely used in coal mine transportation scenarios due to its characteristics of large conveying capacity, high efficiency and stable operation. Conveyor belt devices are mainly composed of a frame, conveyor belt body, drive mechanism and idlers. Its working principle is that the drive mechanism drives the conveyor belt to circulate. Coal is put onto the conveyor belt by the feeding device. With the help of the friction between the conveyor belt and the coal, it moves with the conveyor belt, thereby realizing continuous transportation from one location to another. It plays a key role in coal mining, processing and transportation. However, the existing technology has the following problems: In the process of coal transportation, when dealing with damp coal, some processes require the addition of drying measures along the transportation path. However, when coal is transported on the conveyor belt, the upper layer of coal covers the lower layer, making it difficult for the lower layer of coal to fully contact the drying medium. This results in a slow drying process and uneven drying effect. At the same time, because the humidity of the lower layer of coal is not effectively reduced, it is easy for it to adhere to the surface of the conveyor belt, which not only affects the smoothness of transportation but may also increase the cleaning burden of the conveyor belt, thus adversely affecting the overall transportation efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a continuous coal mine turning conveyor to solve the above-mentioned problems.

[0009] Preferably, the averaging component further includes two first guide plates, two second guide plates, and a third guide plate.

The third guide plate is located in the middle of the slide plate, the two second guide plates are located on both sides of the third guide plate, and the two first guide plates are located on the side of the two second guide plates away from the third guide plate.

[0013] The beneficial effects are: 1. This coal mine turning continuous conveyor device, through the setting of the turning component, enables the first roller, the second roller, and the pressure plate to cooperate to form a concave area on the conveyor belt. With the counterclockwise rotation of the fork plate, the coal in the concave area is lifted and turned to the left. At the same time, the rotation of the lever can push the coal on the fork bar toward the slide plate, preventing the coal from piling up after turning. It achieves the technical effect of automatic turning of the coal on the conveying path and ensuring smooth conveying. After turning, the coal that was originally located in the lower layer is turned into the upper layer, thereby accelerating the drying efficiency and avoiding the problem of uneven drying and residual moisture in the lower layer coal sticking to the conveyor belt due to the covering of the upper layer.

[0014] 2. This coal mine turning and continuous conveying device, through the setting of the equalization component, allows the coal turned by the fork plate to be first pushed to the slide plate by the pusher plate, and under the converging action of the two first guide plates, it enters four feed ports with the same cross-sectional area. The four discharge ports can divide the previously gathered coal into four parts and put them onto the conveyor belt, so that the coal can be more evenly distributed on the conveyor belt. By the sliding rod moving the four pin shafts, the two first movable plates and the two second movable plates swing back and forth, promoting the even falling of coal in the channel, achieving the technical effect of uniform coal distribution, avoiding the problem of local coal accumulation affecting the balance of the conveyor belt and the problem of coal spillage.

[0015] 3. This coal mine tilting continuous conveyor device, through the setting of the crushing component, allows the cam and the lever to work together to make the orifice plate continuously tilt upward and then drop downward. When multiple cone rods drop, they chisel the coal clumps in front of the concave area of ​​the conveyor belt. At the same time, the cone rods achieve rotational crushing through the cooperation of the sliding shaft and the sliding tongue, achieving the technical effect of automatic dispersion of coal clumps and avoiding the problem of large coal clumps getting stuck in the concave area of ​​the conveyor belt and causing material blockage.

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0020] 1. Example 1 Since some processes require additional drying measures along the conveying path when transporting wet coal, and the bottom layer of coal above the conveyor belt dries slowly due to being covered, and is prone to sticking to the conveyor belt due to its high humidity, this embodiment was invented to solve the above problems.

[0021] Please see Figure 1 - Figure 6A coal mine turning and continuous conveying device includes a frame 1 and a conveyor belt 2 installed on top of it. Two mounting frames 3 are fixedly installed on the frame 1, and a turning assembly 4 is arranged between the two mounting frames 3. The turning assembly 4 includes a first roller 41, a second roller 42, and a first rotating shaft 44. Two pressure plates 45 are fixedly connected to the first rotating shaft 44. The two pressure plates 45, through cooperation with the first roller 41 and the second roller 42, can press a recessed area into the conveyor belt 2. Multiple forks 46 are connected to the outer wall of the first rotating shaft 44. The multiple forks 46 are used to turn the coal passing through the recessed area of ​​the conveyor belt 2. The frame 1 and the conveyor belt 2 are both existing technologies. A drive mechanism is set inside the frame 1 to drive the conveyor belt 2 to run. Its specific structure and working principle will not be described in detail below. Figure 1 As a directional reference, conveyor belt 2 transports the coal from right to left as it moves.

[0022] Furthermore, please refer to Figure 3 - Figure 6 The first roller 41 and the second roller 42 are both rotatably mounted on the frame 1. A motor 43 is mounted on the frame 1, and the output end of the motor 43 is connected to the first roller 41. A first shaft 44 is rotatably mounted on two mounting brackets 3. A first gear 47 is fixedly connected to the first roller 41, and a second gear 48 is rotatably mounted on the mounting bracket 3 away from the motor 43. A third gear 49 is fixedly connected to the first shaft 44. The second gear 48 meshes with the first gear 47, and the third gear 49 meshes with the second gear 48. After the motor 43 starts, it drives the first roller 41 to rotate counterclockwise. The rotational speed of the first roller 41 matches the running speed of the conveyor belt 2. The motor 43 provides assistance. When the conveyor belt 2 runs, it drives the second roller 42 to rotate counterclockwise. When the first roller 41 rotates, it drives the second gear 48 to rotate through the first gear 47. The second gear 48 then drives the first shaft 44 to rotate counterclockwise through the third gear 49 (e.g., ...). Figure 4 As shown, the conveyor belt 2 is divided into a carrying section and a return section. The carrying section is where the conveyor belt 2 carries and transports materials, while the return section is where the conveyor belt 2 returns empty after the materials are unloaded. The first roller 41 and the second roller 42 are in contact with the bottom surface of the carrying section, and the two pressure plates 45 are in contact with the top surface of the carrying section. Multiple forks 46 are arranged in a circular array with the first rotating shaft 44 as the center. When the forks 46 move, they pass through the concave area of ​​the conveyor belt 2. When the first rotating shaft 44 rotates, it drives the two pressure plates 45 and the multiple forks 46 to rotate counterclockwise. When the two pressure plates 45 rotate, they also always apply pressure to the carrying section of the conveyor belt 2 to maintain the shape of the concave area. The coal conveyed by the conveyor belt 2 from right to left continuously enters the concave area. When the multiple forks 46 rotate counterclockwise, they can continuously pick up the coal in the concave area and then flip it to the left side of the forks 46 by rotation, thereby achieving the technical effect of flipping the coal.

[0023] In addition, please see Figure 2 - Figure 6A spreading component 5 is installed on the frame 1. The spreading component 5 is used to evenly spread the overturned coal ore on the conveyor belt 2. The spreading component 5 includes a slide plate 51, which is fixedly installed on two mounting frames 3. Multiple forks 52 are fixedly connected to the slide plate 51. Multiple slots are provided on the fork plate 46. The multiple forks 52 are respectively located on the movement trajectory of the multiple slots of the fork plate 46. There is a gap between the slide plate 51 and the conveyor belt 2. The slide plate 51 is inclined, with the end of the slide plate 51 closer to the forks 52 higher than the end farther away from the forks 52. When the fork plate 46 passes through the multiple forks 52, the multiple forks 52... 2. The coal passes through multiple gaps in the fork plate 46, thereby picking up the coal on the fork plate 46 and allowing it to slide along the multiple forks 52 onto the slide plate 51, and then onto the conveyor belt 2. During the coal transport, there are fine coal slags, which refer to coal slag powder and fine coal particles. The fine coal slags will pass through the multiple gaps in the fork plate 46, thus preventing them from being picked up by the fork plate 46. This allows the fine coal slags to continue moving to the left with the conveyor belt 2, and during the leftward movement, they pass under the fork plate 46 and forks 52, as well as the gap between the slide plate 51 and the conveyor belt 2, so that the slide plate 51 does not obstruct the passage of the fine coal slags.

[0024] In addition, please see Figure 2 , Figure 7 - Figure 8 The flipping assembly 4 also includes a second rotating shaft 410, which is rotatably mounted on two mounting brackets 3. A fourth gear 411 is fixedly connected to the second rotating shaft 410, and the fourth gear 411 meshes with the first gear 47. Multiple paddles 412 are fixedly connected to the second rotating shaft 410, and the multiple paddles 412 are all located above the connection between the slide plate 51 and the multiple forks 52. When the first gear 47 rotates counterclockwise, it drives the second rotating shaft 410 to rotate clockwise through the fourth gear 411. The second rotating shaft 410 drives the multiple paddles 412 to rotate clockwise. When the paddles 412 rotate, they can continuously push the coal on the multiple forks 52 toward the slide plate 51, promote the movement of the coal, and prevent the coal from accumulating at the slide plate 51.

[0025] 2. Example 2 Based on Example 1, when coal is fed onto conveyor belt 2 by the feeding device, uneven distribution of coal may occur in some areas. Even after the coal is flipped back onto conveyor belt 2, it will still be unevenly distributed, affecting the balance of conveyor belt 2. This can cause shaking during the conveying process, and uneven distribution of coal can also lead to local accumulation. The accumulated coal is prone to spillage during the conveying process, resulting in waste. This embodiment is invented to solve the above problems.

[0026] Please see Figure 2 , Figure 7 - Figure 9The equalization component 5 also includes two first guide plates 53, two second guide plates 54, and a third guide plate 55. All three are fixedly mounted on the slide rail 51. The third guide plate 55 is located in the middle of the slide rail 51, and the two second guide plates 54 are located on either side of the third guide plate 55. The two first guide plates 53 are located on the side of the two second guide plates 54 furthest from the third guide plate 55. The two first guide plates 53 are inclined, forming four feed inlets between them. The inlet sections of the four feed inlets are... With the same area, two first guide plates 53 are respectively hinged with first movable plates 56, and two second guide plates 54 are respectively hinged with second movable plates 57. Four discharge ports are formed between the two first movable plates 56, the two second movable plates 57, and the third guide plate 55. The cross-sectional area of ​​the discharge ports is larger than that of the inlets. The four inlets and four discharge ports are connected to form four channels. The two inclined first guide plates 53 act as a converging point. Coal ore, propelled to the left by multiple levers 412, enters the slide plate 51. The coal ore is concentrated into the four inlets by the converging effect of the two first guide plates 53 (e.g., ...). Figure 9 As shown in the diagram, after the coal is collected, it can fill the four feed inlets and continue to slide to the left in this state. The coal entering the four feed inlets enters the four channels respectively, and the cross-sectional area of ​​the four channels gradually increases. Therefore, when the coal is discharged from the four discharge outlets, the four discharge outlets can divide the previously collected coal into four parts and put them onto the conveyor belt 2 in a relatively even manner, thereby achieving the technical effect of evenly distributing the coal and making the coal more evenly distributed on the conveyor belt 2.

[0027] It is worth noting that, please refer to Figure 9 , Figure 10 A slide rod 58 is slidably connected to the slide plate 51. A slanted wheel 512 is fixedly connected to the outer wall of the second rotating shaft 410 away from the fourth gear 411. A connecting rod 510 is fixedly connected to the end of the slide rod 58 near the slanted wheel 512. Two rollers 511 are installed on the connecting rod 510. When the slanted wheel 512 moves, it contacts the two rollers 511. Pins 59 are fixedly connected to the two first movable plates 56 and the two second movable plates 57 respectively. The slide rod 58 is provided with four sliding grooves. The four pins 59 are slidably connected to the four sliding grooves of the slide rod 58 respectively. When the second rotating shaft 410 rotates, it drives the slanted wheel 512 to rotate. When the slanted wheel 512 rotates, it alternately drives the connecting rod 510 to move back and forth through the two rollers 511. The connecting rod 510 drives the slide rod 58 to move back and forth. When the slide rod 58 moves back and forth, it can use the four sliding grooves to move the four pins 59 back and forth (e.g., ...). Figure 9As shown), the four pins 59 drive the two first movable plates 56 and the two second movable plates 57 to swing back and forth. The back and forth swing of the two first movable plates 56 and the two second movable plates 57 can promote the falling of coal in the four channels, and the back and forth swinging motion makes the coal slide down more evenly.

[0028] 3. Example 3 Based on Example 1, since some coal mines have agglomeration, resulting in large coal mine agglomerates, when the coal mine agglomerates are so large that their center of gravity cannot move onto the movement trajectory of the fork plate 46, the coal mine agglomerates will get stuck outside the concave area of ​​the conveyor belt 2, making it impossible for the fork plate 46 to pick up the large coal mine agglomerates. As a result, the coal mine agglomerates cannot be flipped in time and get stuck on the conveyor belt 2, causing material blockage. This example is invented to solve the above problems.

[0029] Please see Figure 2 , Figure 11 - Figure 14 A crushing assembly 6 is installed on the frame 1 to crush the lumpy coal on the conveyor belt 2. The crushing assembly 6 includes a third rotating shaft 61, which is rotatably mounted on two mounting brackets 3. A lever 62 is fixedly connected to the third rotating shaft 61. A cam 63 is fixedly connected to the second rotating shaft 410. The lever 62 is located on the movement trajectory of the cam 63. Two cranks 64 are fixedly connected to the third rotating shaft 61. A perforated plate 65 is fixedly connected to the two cranks 64. Multiple cone rods 66 are rotatably connected to the perforated plate 65. When the second rotating shaft 410 rotates clockwise, it drives the cam 63 to rotate clockwise. During one revolution, the cam 63 contacts the lever 62 and drives the lever 62 to swing downward until the cam 63 disengages from the lever 62. When the lever 62 swings downward, it drives the third rotating shaft 61 to rotate counterclockwise. At the same time, the third rotating shaft 61 drives the perforated plate 65 to swing upward through the two cranks 64 (e.g., ...). Figure 11 As shown in the diagram, when the cam 63 disengages from the lever 62, the orifice plate 65 and the two cranks 64 fall back to their original positions under their own weight. The third rotating shaft 61 and the lever 62 also return to their original positions simultaneously. When the orifice plate 65 falls, it drives multiple cone rods 66 to fall. The cone rods 66 are located at the position where the conveyor belt 2 is about to move from right to left into the recessed area. Coal clumps that the fork plate 46 cannot pick up stay at this position. When multiple cone rods 66 fall, they can break up the coal clumps, disperse the coal, and then the fork plate 46 flips it over, achieving the technical effect of automatically breaking up coal clumps. The bottom of the cone rods 66 is rounded to prevent damage to the conveyor belt 2.

[0030] It is worth noting that, please refer to Figure 13 - Figure 14Multiple tapered rods 66 are respectively fixedly connected to the top of sliding shafts 67. Multiple springs 69 are fixedly connected to the top of the orifice plate 65. A pressure block 68 is fixedly connected to the end of each spring 69 away from the orifice plate 65. Multiple round holes are provided on the pressure block 68. Multiple sliding shafts 67 pass through the multiple round holes of the pressure block 68. An annular groove 610 is opened on the sliding shaft 67. A sliding tongue 611 is fixedly installed in the round hole of the pressure block 68. Multiple sliding tongues 611 are slidably connected to multiple annular grooves 610. When the sliding tongues 611 move up and down, they can drive the sliding shafts 67 to rotate through the annular grooves 610 (e.g., Figure 14 As shown, when the orifice plate 65 falls, the orifice plate 65 drives the pressure block 68 to fall synchronously through multiple springs 69. At this time, there is a gap between the pressure block 68 and the orifice plate 65, and the multiple springs 69 are in a slightly compressed state. When the multiple cone rods 66 and the orifice plate 65 move into place, the pressure block 68 continues to fall due to its own gravity and inertia, causing the pressure block 68 to drive multiple sliding shafts 67 to rotate through multiple sliding tongues 611. The multiple sliding shafts 67 drive multiple cone rods 66 to rotate respectively. Subsequently, the pressure block 68 rebounds and resets due to the elastic force of multiple springs 69. The multiple sliding tongues 611 again drive multiple cone rods 66 to rotate through multiple sliding shafts 67, so that the cone rods 66 inserted into the coal clumps can further promote the splitting of the coal clumps and optimize the crushing effect through rotation.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
