Description

Technical Field

[0001] This invention relates to the field of belt conveyor technology, and in particular to a belt conveyor with anti-dropping function and its usage method. Background Technology

[0002] A belt conveyor is short for a belt conveyor. Belt conveyors use the continuous or intermittent movement of a conveyor belt to transport various items of different weights. They can transport various bulk materials as well as various cartons, vegetables, coal and other lightly weighted items, and have a wide range of applications.

[0003] In the process of transporting coal blocks, an external coal mining mechanism extracts a fixed amount of coal each time and places it on a conveyor belt. The conveyor belt then transports the coal to a certain height into the transport vehicle. The conveyor belt consists of a horizontal section and an inclined ascending section. Because the coal blocks are of different sizes, they tend to pile up into small hills when placed. During the later movement of the coal blocks, the coal blocks at the top of the small hills tend to slide down significantly. Furthermore, as the coal blocks rise with the inclined conveyor belt, the fixed amount of coal piled on the belt will tilt and slide downwards under the influence of gravity. This causes disorder in the extracted coal, which is not conducive to unloading the coal blocks and subsequent loading, and may affect the weight of each coal block. On the other hand, the sliding coal blocks tend to roll irregularly to the edge of the conveyor belt, thus squeezing the side wall of the conveyor belt. Coal blocks located at the edge of the conveyor belt tend to have a large discharge range during transmission and unloading, making it inconvenient to concentrate and process them. Therefore, we propose a conveyor belt with anti-falling function and its usage method. Summary of the Invention

[0004] The present invention aims to overcome the shortcomings of the prior art and provide a belt conveyor with anti-dropping function and its usage method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a belt conveyor with anti-dropping function, comprising a mounting frame, two mounting plates symmetrically fixed to the inner wall of the mounting frame, three rollers rotatably connected between the two mounting plates, a belt connected to the surface of the three rollers, and the belt consisting of a horizontal transmission section and an inclined upward transmission section, a motor fixed to the outer wall of the mounting plates and driving the nearest roller to rotate, a limiting mechanism between the belt and the two mounting plates for limiting the transmission trajectory of the belt, a number of partition plates equidistantly fixed to the outer surface of the belt, and a flattening mechanism on the top of the two mounting plates for flattening the coal blocks placed on the top of the belt;

[0006] Each of the two mounting plates has a first guide rail on its side wall. Each partition plate has a mounting groove symmetrically provided on its side wall. A first rotating shaft is rotatably connected to the top surface of the mounting groove. A diversion plate is fixedly connected to the surface of the first rotating shaft. Each first rotating shaft is provided with a flipping mechanism between it and the adjacent first guide rail. This mechanism is used to flip the diversion plate when the partition plate moves upward at an angle. A telescopic scraping mechanism is provided between the mounting groove and the adjacent diversion plate. This mechanism is used to scrape the side wall of the mounting plate during the flipping process of the diversion plate.

[0007] Specifically, the limiting mechanism includes two slides and two sets of first sliding pins. The two slides are respectively opened on the side walls of the two mounting plates on opposite sides. The slides are composed of horizontal slide sections and inclined slide sections. The two sets of first sliding pins are symmetrically fixedly connected to both sides of the belt, and the ends of each set of first sliding pins are slidably inserted into the interior of the adjacent slides.

[0008] Specifically, the leveling mechanism includes a U-shaped plate, with both ends of the U-shaped plate fixedly connected to the top of two mounting plates respectively. Gas springs are symmetrically fixedly connected to the top surface of the inner wall of the U-shaped plate. Fixed plates are fixedly connected to the ends of the extension sections of the two gas springs. A toggle block is fixedly connected between the two fixed plates. A pushing mechanism is provided between the two fixed plates and all the partition plates to drive the two fixed plates to move upward.

[0009] Specifically, the pushing mechanism includes two second sliding pins and multiple pairs of connecting plates. The two second sliding pins are respectively fixedly connected to the side walls of the two fixed plates on opposite sides. The multiple pairs of connecting plates are respectively symmetrically fixedly connected to the top of multiple partition plates. Push plates are fixedly connected to the ends of all connecting plates. Second guide rails are provided on the opposite sides of the two push plates at the top of each partition plate. The second guide rails are composed of a first horizontal groove and a first inclined groove that are interconnected.

[0010] Specifically, the first guide rail is composed of a first guide groove, a second inclined groove, a second guide groove, a third inclined groove, and a third guide groove that are interconnected.

[0011] Specifically, a first rectangular plate and a second rectangular plate are fixedly connected to the inner wall of the second guide groove. Multiple sets of first protrusions are sequentially provided on the side wall of the first rectangular plate. The first protrusion is composed of a trapezoidal block and a first plane. Multiple sets of second protrusions are provided on one side of the side wall of the second rectangular plate. The second protrusion is composed of a trapezoidal groove and a second plane, and the trapezoidal block and the trapezoidal groove are adapted to each other.

[0012] Specifically, a first shielding plate is fixedly connected to the upper side wall of the partition, and a second shielding plate is fixedly connected to both ends of the first shielding plate.

[0013] Specifically, the flipping mechanism includes a second rotating shaft and a first rack. The second rotating shaft is rotatably connected to the top of the partition plate. The lower end of the second rotating shaft passes through the partition plate and extends into the mounting groove, where it is fixedly connected to the end of the first rotating shaft. A first gear is fixedly connected to the top of the second rotating shaft. The first rack is slidably connected to the top of the partition plate and meshes with the first gear. A pull pin is fixedly connected to the end of the first rack, and the end of the pull pin is slidably inserted into the interior of the first guide rail.

[0014] Specifically, the telescopic scraping mechanism includes an insertion slot located at the end of the diversion plate. A scraping plate is slidably inserted into the inner wall of the insertion slot. A second rack is fixedly embedded in the side wall of the scraping plate. An opening is provided in the inner wall of the insertion slot, penetrating the side wall of the diversion plate. A third rack is slidably connected to the inner wall of the opening. A third rotating shaft is rotatably connected between the inner walls of the opening. A second gear is fixedly connected to the third rotating shaft, and the two sides of the second gear mesh with the second rack and the third rack, respectively. A rotating plate is rotatably connected to the end of the third rack facing away from the second gear and away from the second rotating shaft. The end of the rotating plate facing away from the third rack is rotatably connected to the inner wall of the mounting slot.

[0015] A method for using a belt conveyor with anti-drop-material function, the method specifically includes the following steps:

[0016] Step 1, Stable transport of coal blocks: The motor drives the roller to rotate, thereby driving the belt for transport. The transport trajectory of the belt is limited by the limiting mechanism. Then, the weighed coal blocks are placed between the two partition plates of the horizontal transport section of the belt. The leveling mechanism flattens the coal blocks piled on top of the belt, reducing the height of the coal block pile. The coal blocks are transported as the belt is conveyed.

[0017] Step 2, pushing the coal block: As the separator plate moves upward at an angle, the diversion plate is flipped by the flipping mechanism. The two rotating diversion plates on one side of the separator plate push the coal block towards the middle of the conveyor belt.

[0018] Step 3: Scraping the coal blocks: As the partition plate rotates, the linkage telescopic scraping mechanism moves to scrape the coal blocks adhering to the side wall of the mounting plate.

[0019] The beneficial effects of this invention are:

[0020] 1. By setting a limit mechanism, the transmission trajectory of the belt can be limited, thereby maintaining the stability of belt transmission;

[0021] 2. By setting up a leveling mechanism, the coal blocks piled on top of the conveyor belt can be leveled, reducing the height of the coal blocks and preventing them from piling up too high and sliding over the partition plate when being conveyed at an angle upward.

[0022] 3. By setting up partition plates, it is convenient to block the flattened coal blocks when they are being transported at an angle upward, so as to prevent the coal blocks from sliding directly down the surface of the conveyor belt, thus affecting the transport of the coal blocks;

[0023] 4. By setting the first guide rail, the diversion plate, the flipping mechanism, and the telescopic scraping mechanism, the coal blocks on the belt can be pushed towards the middle, so that the coal blocks slide along the surface of the diversion plate towards the middle of the belt. This helps to reduce the pressure on the side wall of the mounting plate when the coal blocks slide down during the upward oblique transmission. At the same time, the coal blocks pushed to the middle facilitate the centralized unloading of the coal blocks later, and can also scrape the coal blocks adhering to the side wall of the mounting plate.

[0024] 5. By setting up a first baffle plate, a second baffle plate, and a diversion plate, the two diversion plates and the first and second baffle plates together form a protective cover, which helps to block the coal blocks in the middle of the belt. During the process of the partition plate moving obliquely upward, it prevents the coal blocks diverted to the middle of the belt by the diversion plate from accumulating and rolling down from the top of the partition plate, thus affecting the quantitative transmission of coal blocks between each partition plate.

[0025] 6. By setting a second guide groove, a first protruding member, a second protruding member, and a pulling pin, the pulling pin will cause the diversion plate to slightly rotate back and forth as it passes between the first rectangular plate and the second rectangular plate. During the back and forth rotation and shaking of the diversion plate, it is beneficial to shake the coal blocks on one side of the diversion plate, so that the coal blocks are completely unloaded from the end of the belt, avoiding the coal blocks from adhering to the side wall of the diversion plate. This helps to ensure that the amount of coal blocks unloaded from each partition plate does not change, making it convenient for workers to perform quantitative packaging.

[0049] The following will describe in detail, with reference to the accompanying drawings, embodiments of the present invention. Detailed Implementation

[0050] The present invention will be further described below with reference to embodiments:

[0051] like Figures 1-16 As shown, a belt conveyor with anti-dropping function includes a mounting frame 1. Two mounting plates 2 are symmetrically fixed to the inner wall of the mounting frame 1. Three rollers 3 are rotatably connected between the two mounting plates 2. A belt 4 is connected to the surface of the three rollers 3. The belt 4 consists of a horizontal transmission section and an inclined upward transmission section. A motor 5 is fixed to the outer wall of the mounting plate 2 and drives the nearest roller 3 to rotate. The output shaft end of the motor 5 passes through the nearest mounting plate 2 and extends out to be fixedly connected to the end of the nearest roller 3. The motor 5 is started by an external controller. The output shaft of the motor 5 drives the roller 3 fixedly connected to it to rotate. The rotating roller 3 transmits the belt 4 connected to the surface of the three rollers 3.

[0052] A limiting mechanism is provided between the belt 4 and the two mounting plates 2 to limit the transmission trajectory of the belt 4. The limiting mechanism includes two slide grooves 11 and two sets of first sliding pins 12. The two slide grooves 11 are respectively opened on the side walls of the two mounting plates 2 on opposite sides. The slide grooves 11 are composed of horizontal slide sections and inclined slide sections. The two sets of first sliding pins 12 are symmetrically fixedly connected to both sides of the belt 4, and the ends of each set of first sliding pins 12 are slidably inserted into the interior of the adjacent slide grooves 11. The first sliding pins 12 slide along the slide grooves 11. When the belt 4 is transmitting, the transmission trajectory of the belt 4 can be limited, thereby maintaining the stability of the belt 4 during transmission. During operation, the interior of the slide grooves 11 can facilitate the insertion of the first sliding pins 12. With the help of the trajectory limitation of the slide grooves 11, it is beneficial to limit the transmission trajectory of the belt 4 and limit the belt 4 to the surface of the three rollers 3. This is beneficial to maintain the horizontal and inclined transmission of the belt 4, thereby facilitating the transmission of coal blocks and reducing the workload.

[0053] Several partition plates 6 are fixed at equal intervals on the outer surface of the belt 4 to block the coal blocks when they are being transported at an angle upwards, thus preventing the coal blocks from sliding directly down the surface of the belt and affecting the transport of the coal blocks.

[0054] The tops of the two mounting plates 2 are equipped with a leveling mechanism to flatten the coal blocks placed on top of the conveyor belt 4. The leveling mechanism includes a U-shaped plate 31, with both ends of the U-shaped plate 31 fixedly connected to the tops of the two mounting plates 2. Gas springs 32 are symmetrically fixedly connected to the top surface of the inner wall of the U-shaped plate 31. Fixed plates 33 are fixedly connected to the ends of the extension sections of the two gas springs 32. A moving block 34 is fixedly connected between the two fixed plates 33. A pushing mechanism is provided between the two fixed plates 33 and all the partition plates 6 to drive the two fixed plates 33 to move upward. During operation, when the external coal blocks are placed between the two partition plates 6 on the conveyor belt 4, due to the different sizes of the coal blocks, they tend to pile up into a small hill. During the later process of the coal blocks moving obliquely upward, the coal blocks at the top of the small hill will be flattened. Coal blocks are prone to sliding down steeply, and if the slope is too steep, they may flip over the partition plate 6. This technical solution can solve the above problems. The specific implementation method is as follows: In the initial state, under the support of the gas spring 32 on the two fixed plates 33, the agitator 34 is supported and installed above the belt between the two mounting plates 2. When the belt 4 drives the coal blocks to be transported, the agitator 34 will agitate the top slope of the piled coal blocks, flatten the coal, facilitate the transport of the coal, and prevent the coal blocks from piling up too high and sliding down and flipping over the partition plate 6 during the upward transport, thus affecting the weight of each coal block. As the partition plate 6 on the belt 4 moves toward the agitator 34, the fixed plate 33 connected to the agitator 34 moves upward through the linkage of the pushing mechanism, thus facilitating the partition plate 6 to pass under the agitator 34.

[0055] The leveling mechanism can shorten the height of the coal block stack, preventing the coal blocks from sliding down and overturning over the partition plate 6 when the coal blocks are transported obliquely upwards by the belt 4. The partition plate 6 is designed to block the leveled coal blocks when they are transported obliquely upwards, preventing the coal blocks from sliding down directly along the surface of the belt 4, thus affecting the transport of the coal blocks.

[0056] The pushing mechanism includes two second sliding pins 35 and multiple pairs of connecting plates 36. The two second sliding pins 35 are respectively fixedly connected to the side walls of the opposite sides of the two fixed plates 33. The multiple pairs of connecting plates 36 are respectively symmetrically fixedly connected to the top of multiple partition plates 6. Pushing plates 37 are fixedly connected to the ends of all connecting plates 36. Second guide rails 38 are provided on the opposite sides of the two pushing plates 37 at the top of each partition plate 6. The second guide rails 38 are composed of a first horizontal groove 3801 and a first inclined groove 3802 that are interconnected. When the belt 4 is transmitting, the second sliding pins 35 slide along the second guide rails 38. During operation, the connecting plates 36 can support and install the pushing plates 37. During the process of the partition plate 6 moving towards the actuating block 34, the inner wall of the first inclined groove 3802 on the pushing plate 37 will touch the second sliding pins 35 in advance, so that the second sliding pins 35 slide along the trajectory of the first inclined groove 3802 and move with the partition plate. As the partition plate 6 continues to move, the inner wall of the first inclined groove 3802 pushes the second sliding pin 35, thereby pushing the second sliding pin 35 to drive the fixed plate 33 to compress the air spring 32 upward, so that the second sliding pin 35 drives the actuating block 34 to move upward, thus making way for the movement of the partition plate 6. Then the second sliding pin 35 slides along the first inclined groove 3802 to the inside of the first horizontal groove 3801. During the contact between the surface of the first horizontal groove 3801 and the second sliding pin 35, the fixed plate 33 is kept in the state of compressing the air spring 32 upward, so that the partition plate 6 can pass under the actuating block 34. After the partition plate 6 moves past the bottom of the actuating block 34, the second sliding pin 35 slides away along the inside of the first inclined groove 3802. Then the compressed air spring 32 pushes the fixed plate 33 connected to the actuating block 34 to move downward and reset, so that the actuating block 34 can continue to flatten the subsequent coal blocks after resetting.

[0057] The two mounting plates 2 are respectively provided with first guide rails 9 on their side walls. The first guide rails 9 are composed of a first guide groove 901, a second inclined groove 902, a second guide groove 903, a third inclined groove 904, and a third guide groove 905 that are interconnected. During operation, the first guide rails 9 facilitate the linkage of the diversion plate 10 to perform diversion work. When the partition plate 6 moves upward at an angle, it simultaneously drives the diversion plate 10, which is set on the side wall of the partition plate 6, to move upward at an angle. Thus, under the push of the second inclined groove 902, the diversion plate 10 is triggered to perform diversion work, which is beneficial to divert the coal blocks conveyed on the belt 4 to the middle of the belt 4. After the coal blocks on the belt 4 are unloaded, the diversion plate 10 is reset with the help of the third inclined groove 904.

[0058] Each partition plate 6 has a symmetrically arranged mounting groove 7 on its side wall. A first rotating shaft 8 is rotatably connected to the top surface inside the mounting groove 7. A flow guide plate 10 is fixedly connected to the surface of the first rotating shaft 8. Each first rotating shaft 8 is provided with a flipping mechanism between it and the adjacent first guide rail 9. The flipping mechanism is used to drive the flow guide plate 10 to flip when the partition plate 6 moves upward at an angle. The flipping mechanism includes a second rotating shaft 13 and a first rack 15. The second rotating shaft 13 is rotatably connected to the top of the partition plate 6. The lower end of the second rotating shaft 13 passes through the partition plate 6 and extends into the mounting groove 7 and is fixedly connected to the end of the first rotating shaft 8. A first gear 14 is fixedly connected to the top of the second rotating shaft 13. The first rack 15 is slidably connected to the top of the partition plate 6 and meshes with the first gear 14. A pull pin 16 is fixedly connected to the end of the first rack 15. The end of the pull pin 16 is slidably inserted into the inside of the first guide rail 9.

[0059] During operation, in the initial state, the diversion plate 10 is housed inside the mounting slot 7, facilitating the movement of the partition plate 6 and the initial placement of coal blocks, preventing interference with the placement of external coal blocks onto the conveyor belt 4. As the conveyor belt 4 transmits, it drives the partition plate 6 to move obliquely upwards. The pull pin 16 connected to the side wall of the first rack 15 moves from the first guide slot 901 into the second oblique slot 902. Under the push of the inner wall of the second oblique slot 902, the pull pin 16 drives the first rack 15 to move. Since the first rack 15 meshes with the first gear 14 connected to the end of the second rotating shaft 13, the movement of the first rack 15 drives the first gear 14 to rotate, thereby causing the first rotating shaft 8 connected to the diversion plate 10 to rotate, thus allowing the diversion plate 10 to be retracted. The guide plate 10 inside the mounting groove 7 flips outward, and the flipped-out guide plate 10 pushes the coal blocks that are being transported obliquely upward toward the middle of the belt 4, preventing the coal blocks from sliding down the slope and causing accumulation and compression on the side wall of the mounting plate 2. When the pull pin 16 slides along the inside of the second guide groove 903, it helps to maintain the state of the guide plate 10 after it has flipped out of the mounting groove 7. During the process of the coal blocks being transported obliquely upward, the guide plate 10 after flipping maintains the state of guiding the sliding coal blocks. When the pull pin 16 slides along the inside of the third oblique groove 904, the pull pin 16 drives the first rack 15 to reset under the push of the inner wall of the third oblique groove 904, and at the same time drives the first gear 14 connected to the surface of the second rotating shaft 13 to rotate, flipping the guide plate 10 back into the mounting groove 7.

[0060] A first baffle plate 17 is fixedly connected to the upper side wall of the partition plate 6, and a second baffle plate 18 is fixedly connected to both ends of the first baffle plate 17. During operation, as the partition plate 6 moves along the inclined section of the belt 4, guided by the second inclined groove 902, the two diversion plates 10 on one side of the partition plate 6 flip to form a figure-eight shape. At this time, the tops of the two diversion plates 10 contact the side walls of the two second baffle plates 18, thereby forming a protective cover together with the two diversion plates 10, the first baffle plate 17, and the second baffle plate 18. This helps to block the coal blocks in the middle of the belt 4. During the upward movement of the partition plate 6, the coal blocks that are diverted to the middle of the belt 4 by the diversion plates 10 are prevented from accumulating and rolling down from the top of the partition plate 6, thus affecting the quantitative transfer of coal blocks between each partition plate 6.

[0061] A first rectangular plate 27 and a second rectangular plate 28 are fixedly connected to the inner wall of the second guide groove 903. Multiple sets of first protrusions 29 are sequentially arranged on the side wall of the first rectangular plate 27. Each first protrusion 29 is composed of a trapezoidal block 2901 and a first plane 2902. Multiple sets of second protrusions 30 are arranged on one side of the side wall of the second rectangular plate 28. Each second protrusion 30 is composed of a trapezoidal groove 3001 and a second plane 3002, and the trapezoidal block 2901 is adapted to the trapezoidal groove 3001. During operation, as the pull pin 16 moves along the inner wall of the second guide groove 903, it passes between the trapezoidal block 2901 and the trapezoidal groove 3001. Under the push of the inclined surface of the trapezoidal block 2901 against the pull pin 16, the pull pin 16 drives the first rack 15 to move along the top of the partition plate 6. Then, under the push of the inclined groove wall of the trapezoidal groove 3001, the pull pin 16 is moved towards the first... One side of the plane 2902 is pushed to reset, thereby driving the first rack 15 to reset. As the pulling pin 16 passes between the first rectangular plate 27 and the second rectangular plate 28, under the combined pushing of multiple sets of first protrusions 29 and second protrusions 30, the pulling pin 16 connected to the first rack 15 is pushed to move back and forth along the top of the partition plate 6. During the process of the first rack 15 sliding back and forth along the top of the partition plate 6, it will drive the first gear 14 connected to the second rotating shaft 13 to rotate back and forth, thereby driving the diversion plate 10 to rotate slightly back and forth. During the back and forth rotation and shaking of the diversion plate 10, it is beneficial to shake the coal blocks on one side of the diversion plate 10, so that the coal blocks are completely unloaded from the end of the belt 4, avoiding the coal blocks from adhering to the side wall of the diversion plate 10. This helps to ensure that the amount of coal blocks unloaded from each partition plate 6 does not change, which is convenient for the staff to carry out quantitative packaging.

[0062] A telescopic scraping mechanism is provided between the mounting slot 7 and the adjacent diversion plate 10 to scrape the side wall of the mounting plate 2 during the flipping of the diversion plate 10. The telescopic scraping mechanism includes an insertion slot 19, which is opened at the end of the diversion plate 10. A scraping plate 20 is slidably inserted into the inner wall of the insertion slot 19. A second rack 21 is fixedly embedded in the side wall of the scraping plate 20. An opening 22 is opened in the inner wall of the insertion slot 19, which penetrates the side wall of the diversion plate 10. A third rack 23 is slidably connected to the inner wall of 2, and a third shaft 24 is rotatably connected between the inner walls of the through 22. A second gear 25 is fixedly connected to the third shaft 24, and the two sides of the second gear 25 mesh with the second rack 21 and the third rack 23 respectively. A rotating plate 26 is rotatably connected to the end of the third rack 23 away from the second shaft 13 on the side facing away from the second gear 25. The end of the rotating plate 26 facing away from the third rack 23 is rotatably connected to the inner wall of the mounting groove 7.

[0063] During operation, as the diversion plate 10 rotates outward from inside the mounting groove 7, one end of the rotating plate 26 is rotatably connected to the inner wall of the mounting groove 7. Therefore, when the diversion plate 10 rotates around the axis of the first rotating shaft 8, the pulling force of the rotating plate 26 pulls the third rack 23 to slide along the inner wall of the opening 22. Since the second gear 25 meshes with both the second rack 21 and the third rack 23 simultaneously, during the movement of the third rack 23, the rotating second gear 25 drives the second rack 21, which is connected to the side wall of the scraper plate 20, to move outward along the inner wall of the insertion groove 19. One end of the scraper 20 extends out of the insertion slot 19. The extended end of the scraper 20 contacts the side wall of the mounting plate 2. On the one hand, this helps the guide plate 10 push the coal blocks on the belt 4 towards the middle of the belt 4, making it easier to unload the coal blocks in a concentrated manner. This avoids the coal blocks sliding downwards and accumulating on the side wall of the mounting plate 2 during the upward oblique transmission. On the other hand, it helps to scrape the coal blocks on the side wall of the mounting plate 2 during the transmission process, preventing the coal blocks from sticking to the side wall of the mounting plate 2 and being difficult to unload, thus affecting the amount of coal after unloading.

[0064] A method for using a belt conveyor with anti-drop-material function, the method specifically includes the following steps:

[0065] Step 1, Stable transport of coal blocks: The motor 5 drives the roller 3 to rotate, thereby driving the belt 4 to transport the coal blocks. The transport trajectory of the belt 4 is limited by the limiting mechanism. Then, the weighed coal blocks are placed between the two partition plates 6 in the horizontal transport section of the belt 4. The coal blocks piled on top of the belt 4 are flattened by the leveling mechanism to shorten the height of the coal block pile. The coal blocks are transported with the belt 4.

[0066] Step 2, pushing the coal block: As the partition plate 6 moves upward at an angle, the diversion plate 10 is flipped by the flipping mechanism. The two rotating diversion plates 10 on one side of the partition plate 6 push the coal block towards the middle of the belt 4.

[0067] Step 3: Scraping the coal blocks: As the partition plate 6 rotates, the linkage telescopic scraping mechanism moves to scrape the coal blocks adhering to the side wall of the mounting plate 2.

[0068] Working principle of this invention:

[0069] The motor 5 is started by the controller of the external device. The output shaft of the motor 5 will drive the roller 3 fixedly connected to it to rotate. The rotating roller 3 transmits the belt 4 which is connected to the surface of the three roller 3. The transmission trajectory of the belt 4 is limited by the limiting mechanism, thereby maintaining the stability of the belt 4 during transmission.

[0070] When a certain quantity of coal blocks needs to be transported to a certain height, the weighed coal blocks are placed between two partition plates 6 on the horizontal transmission section of the belt 4 with the help of external feeding equipment. As the belt 4 is transported, the coal blocks piled on top of the belt 4 are flattened by a leveling mechanism, which shortens the height of the coal block pile and prevents the coal blocks from sliding down and overturning over the partition plates 6 when the coal blocks are transported obliquely upwards. The partition plates 6 are designed to block the flattened coal blocks when the coal blocks are transported obliquely upwards, preventing the coal blocks from sliding down directly along the surface of the belt 4, thus affecting the transport of the coal blocks.

[0071] During the upward oblique transport process of the partition plate 6, the first guide rail 9 and the flipping mechanism drive the first rotating shaft 8 connected to the diversion plate 10 to rotate, thereby causing the diversion plate 10 to flip outward from the mounting groove 7. With the assistance of the diversion plates 10 that symmetrically flip and extend from the side wall of the partition plate 6 and the telescopic scraping mechanism, the coal blocks on the belt 4 are pushed towards the middle, so that the coal blocks slide along the surface of the diversion plate 10 towards the middle of the belt 4. This helps to reduce the pressure on the side wall of the mounting plate 2 caused by the coal blocks sliding down during the upward oblique transport process. At the same time, pushing the coal blocks to the middle facilitates the centralized unloading of the coal blocks later.
