Description

Technical Field

[0001] This invention relates to the field of automatic control technology, specifically to an automatic material stacking control system and device for bucket wheel excavators. Background Technology

[0002] A bucket wheel stacker-reclaimer is a high-efficiency loading and unloading machine used in large dry bulk cargo yards, capable of both stacking and reclaiming materials. It consists of a belt conveyor arm that can tilt and swing horizontally, along with bucket wheels at its front end, a frame, and a running mechanism. The belt can run in both directions. It utilizes the bucket wheels for continuous material reclaiming and the onboard belt conveyor for continuous material stacking. It is a specialized machine for bulk material storage yards, evolved from the bucket wheel excavator. It can be combined with unloading machines, belt conveyors, and loading machines to form a mechanized transportation system for storage yards. Its production capacity can reach over 10,000 tons per hour. Bucket wheel stacker-reclaimers operate with high regularity and are easily automated. They are commonly used equipment in the fuel systems of thermal power plants.

[0003] However, when existing bucket wheel reclaimers are used for material collection, sometimes the fuel pile is too high. After the bucket scoops up the fuel, because most buckets have open tops, the fuel spills and spills to both sides of the bucket during the scooping and rearward rotation process, causing trouble for subsequent cleaning. At the same time, the floating fuel causes a lot of dust, affecting the respiratory health of workers. In addition, when the fuel is reduced to a small amount, the highest point of the fuel is relatively low, and the collection work still requires manual control. The remaining fuel needs to be handled manually. Furthermore, the existing buckets are too large, taking up a lot of space and are inconvenient to use in small factory buildings. If the buckets are too small, it will lead to low transportation efficiency.

[0004] To address the aforementioned issues, there is an urgent need for innovative design based on the existing automatic stacking control system and devices for bucket wheel excavators. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic stacking control system and device for bucket wheel excavators, addressing the aforementioned technical problems. Existing automatic stacking control systems and devices for bucket wheel excavators, due to the open top of most buckets, cause fuel to spill and scatter to both sides of the bucket during the scooping and rearward rotation process, resulting in subsequent cleaning difficulties. Furthermore, when the fuel level is lowered, the highest point of the fuel is relatively flat, requiring manual control for material handling. Additionally, excessively large buckets occupy a lot of space, making them inconvenient for use in small workshops, while excessively small buckets lead to low transportation efficiency. This invention provides a significantly different solution from existing technologies.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An automatic stacking control system for a bucket wheel excavator includes a scanning module, which further includes an infrared detection unit for detecting fuel height. The scanning module is connected to a control module, which includes a control unit, an image generation unit, a position determination unit, and an angle determination unit. The control unit is used to calculate and control the opening and closing of the electrical system. The image generation unit transmits the image scanned by the infrared detection unit to the control unit for analysis and processing. The position determination unit determines the fuel position. The angle determination unit calculates the angle that the adjustment module needs to adjust based on the fuel height. The control module is connected to an adjustment module, which includes a drive motor unit for adjusting the bucket's opening angle.

[0018] Preferably, the adjusting assembly includes a sliding main rod, which is slidably disposed on the inner wall of one side of the fixed plate. A threaded rod is installed at the left end of the sliding main rod, and a pull rod is installed at the top of one end of the sliding main rod. A rotating disk is sleeved on the outer surface of the threaded rod, and a sliding block is installed on the inner wall of the rotating disk. A pulley set is sleeved on the outer surface of the rotating disk, and a helical gear set is installed at one end of the pulley set. A spur gear is installed on one side of the helical gear set. Movable plates are movably installed on both sides of one end of the sliding main rod, and a limit plate is movably installed at one end of the movable plate. The limit plate is installed at the front end of the bucket assembly, and a sliding insert rod is installed at the right end of the sliding main rod.

[0019] Preferably, the sliding block is threadedly engaged with the surface of the threaded rod, one end of the pull rod is embedded in the inner wall of the rotating disk and slidably connected to the inner wall of the rotating disk, and the rotating disk can rotate on the surface of the threaded rod under the pull of the pull rod. The sliding insert is set on the inner wall of the limiting track, the first arc track and the second arc track, and can slide in a limited manner on the inner wall of the limiting track, the first arc track and the second arc track. The sliding main rod is set at the front end of the disk.

[0020] Preferably, the bucket assembly includes a side bucket mounted on the back of a limiting plate. The side buckets are configured in two sets, with a middle bucket slidably and limitingly mounted between the two sets of side buckets. A roller is mounted on the bottom of one side of each side bucket, and a limiting sleeve is mounted on one side of the top of each side bucket. A side top cover is slidably and limitingly mounted on the inner wall of the limiting sleeve. The number of side top covers is configured in two sets, with a middle cover slidably and limitingly mounted between the two sets of side top covers. A rack is mounted on the bottom of the middle cover.

[0021] Preferably, one side of the side bucket is installed with the end of the telescopic rod, the rack is meshed with the top of the flat gear, one side of the side top cover is slidably connected to the inner wall of the limiting sleeve, and the rotation path part of the bucket assembly is located inside the dustproof box.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] This invention incorporates an adjustment component. Driven by the drive component, the adjustment component engages with the first and second arc-shaped rails on the disc mounting component. The side bucket, via a limiting sleeve, causes the side top cover to converge towards the center, reducing the distance between the side bucket and the middle bucket and thus minimizing the space of the bucket assembly. Simultaneously, a pull rod moves the rotating disk, and the sliding block on the inner side slides within the threads of the threaded rod, causing the rotating disk to rotate. This drives the flat gear to move the middle cover, which is meshed with it at the top, forward. The middle cover then moves the side top cover, which had just been retracted, forward synchronously within the limiting sleeve and on top of the side and middle buckets, covering the tops of the shrinking side and middle buckets. This creates a sealed space for the bucket assembly, preventing fuel leakage from both sides during transport and avoiding fuel spillage during delivery.

[0024] This invention uses a sliding rod to move the sliding main rod according to the curvature of the first arc-shaped rail, causing the movable plate to expand or retract to both sides. This expands or contracts the limiting plate and side buckets, allowing the space of the bucket assembly to expand or shrink. Simultaneously, the sliding main rod also drives the pull rod to move the rotating disk. During the rotation of the rotating disk, the inner sliding block slides on the inner thread of the threaded rod, causing the rotating disk to rotate. The rotating disk drives the flat gear to rotate, causing the rack and middle cover to move backward. The middle cover, in turn, causes the previously unfolded side top cover to move backward synchronously inside the limiting sleeve and on the tops of the side buckets and middle buckets. The bucket assembly opens by opening the side bucket and the middle bucket to form a bucket. When the bucket assembly contacts the top of the fuel and scoops up the fuel, it expands and enlarges, then shrinks and merges along the way to compress and gather the fuel, temporarily compressing it into blocks. The purpose is to save space and allow the bucket assembly to scoop up more fuel each time. When it reaches the dust box, the bucket assembly opens again, allowing the temporarily compressed fuel to fall slowly inside the dust box and onto the conveyor belt intact without falling and scattering. The compressed and gathered fuel can also save space in later use or transportation, making it convenient for use in small factories.

[0025] When the fuel stack is reduced to a small amount, the present invention uses an infrared scanner to scan in real time the height of the fuel stack after it has been moved. The control center then synchronously starts the drive motor to rotate, which drives the main shaft to rotate the mounting plate. This causes the entire disc mounting assembly to rotate, and the first and second arc-shaped rails to finely adjust their angles. When the angle of the first and second arc-shaped rails changes, the opening and closing positions of multiple bucket components also change accordingly. This allows the invention to adjust the scooping position of the fuel in real time according to the height of the fuel being removed, achieving a comprehensive effect applicable to the transportation of fuel at different heights.

[0026] This invention achieves the simultaneous enlargement and reduction of the space of multiple bucket components, as well as the opening and closing of the top cover, through the linkage of the automatic stacking equipment's shoveling of fuel. It requires no electricity, saving power resources, requires no manual operation, is fully automated, and is more intelligent. It improves fuel transportation efficiency, increases the cleanliness of the working environment, reduces dust generation, and protects the physical and mental health of other nearby workers.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Please see Figure 11 An automatic stacking control system for a bucket wheel excavator includes a scanning module, which further includes an infrared detection unit for detecting fuel height. The scanning module is connected to a control module, which includes a control unit, an image generation unit, a position determination unit, and an angle determination unit. The control unit is used to calculate and control the opening and closing of the electrical system. The image generation unit transmits the image scanned by the infrared detection unit to the control unit for analysis and processing. The position determination unit determines the fuel position. The angle determination unit calculates the angle that the adjustment module needs to adjust based on the fuel height. The control module is connected to an adjustment module, which includes a drive motor unit for adjusting the bucket's opening angle.

[0041] Please see Figure 1 - Figure 10 The system includes an automatic stacking device 1, which also includes a traveling vehicle 10. An infrared scanner 101 and a control center 102 are installed at the front end of the traveling vehicle 10. A mounting frame 11 is provided on one side of the traveling vehicle 10. A mounting plate 16 is installed on one end of the mounting frame 11. A main shaft 12 is sleeved on the inner wall of the mounting plate 16. A drive motor 13 is provided at the end of the mounting frame 11. A gear 14 is installed at the output end of the drive motor 13. A gear plate 15 is sleeved on the outer surface of the main shaft 12. The gear plate 15 meshes with the gear 14. A mounting rod 17 is installed on the outer surface of the mounting plate 16. The control center 102 controls the traveling vehicle 10 to move to the side of the fuel pile. Then, the infrared scanner 101 is activated to scan the fuel pile. The scanner transmits the image to the control center 102. Then, the control center 102 calculates the position and height of the fuel pile. At this time, the traveling vehicle 10 is finely adjusted to align the bucket assembly 5 with the position of the fuel pile.

[0042] A dustproof box 103 is installed on one side of the mounting frame 11, and a conveyor belt 18 is set at the bottom of the mounting frame 11. The dustproof box 103 is set directly above the conveyor belt 18. The dustproof box 103 is used to prevent dust from spreading everywhere. The internal space of the dustproof box 103 is narrow, and the bottom is almost touching the surface of the conveyor belt 18, so that the fuel that is compressed into blocks falls slowly inside the dustproof box 103 and falls completely onto the conveyor belt 18 without falling and scattering. The compressed and gathered fuel can also save space in the later storage or transportation.

[0043] Furthermore, such as Figure 4 - Figure 7 As shown, a disc mounting assembly 2 is installed at the end of the mounting rod 17. The disc mounting assembly 2 is used to install the drive assembly 3, the adjustment assembly 4, and to adjust the opening and closing cover of the bucket assembly 5. The disc mounting assembly 2 includes a disc 20, which is installed at the end of the mounting rod 17. A side rail 21 is provided on the outer surface of the disc 20. A limit rail 22 is installed at the front end of the disc 20. A first arc-shaped rail 23 is installed on the lower left side of the limit rail 22, and a second arc-shaped rail 24 is installed on the right side of the limit rail 22. A toothed ring 25 is installed on the back of the disc 20, and a second toothed ring 26 is movably installed on the back of the disc 20. A second drive motor 27 is provided on the back of the disc 20. Gear 28 is installed at the output end of 27. The disc 20 is sleeved on the surface of the mounting plate 16 through the mounting rod 17. The inner wall of the mounting plate 16 is fixedly installed on the outer surface of the main shaft 12. Gear ring 26 is rotatably connected to the back of the disc 20. Gear 28 is meshed with gear ring 26. The first arc-shaped rail 23 and the limiting rail 22 are interconnected with the second arc-shaped rail 24. In real-time use, when the angle position of the first arc-shaped rail 23 and the second arc-shaped rail 24 changes, the opening and closing position of the bucket assembly 5 will also change accordingly to achieve the height of descent when the fuel is taken away. The adjusting component 4 synchronously drives the bucket assembly 5 to make corresponding changes to adjust the position of the scooped fuel.

[0044] Furthermore, such as Figure 8As shown, the drive assembly 3 is installed on one side of the disc mounting assembly 2. The drive assembly 3 is used to drive the bucket assembly 5 when it scoops material. The drive assembly 3 includes a fixed plate 30, a rotating shaft 31 is movably sleeved on the inner wall of the fixed plate 30, a gear 32 is installed at the end of the rotating shaft 31, a gear 4 33 is sleeved on the outer surface of the middle part of the rotating shaft 31, a limiter 34 is installed at the right end of the fixed plate 30, a main wheel 35 is installed in the middle of the limiter 34, a secondary wheel 36 is installed on the inner side of the limiter 34, a side plate 37 is installed at the left end of the fixed plate 30, a telescopic rod 38 is installed on the inner side of the side plate 37, the fixed plate 30 is tumblingly connected to the side rail 21 through the main wheel 35 of the limiter 34, the secondary wheel 36 abuts against both sides of the edge of the disc 20, the gear 32 meshes with the gear ring 25, and the gear 4 32 meshes with the gear ring 25. 3 is engaged with gear ring 26, and shaft 31 is rotatably connected to the inner wall of fixed plate 30. Drive motor 27 drives gear 28 to rotate. Gear 28 drives gear ring 26 to rotate. Gear ring 26 rotates on disc 20 and drives gear 4 33 to rotate. When gear 4 33 rotates, it drives shaft 31 of drive assembly 3 to rotate on the inner wall of fixed plate 30. Gear 32 rotates synchronously on the surface of gear ring 25 to limit movement. Drive motor 27 causes drive assembly 3 to drive bucket assembly 5 to rotate on the back of disc 20. When bucket assembly 5 rotates, main wheel 35 of limiter 34 rolls in side rail 21, while auxiliary wheel 36 rolls on both sides of the edge of disc 20 to limit movement.

[0045] Furthermore, such as Figure 8 - Figure 9As shown, the adjusting component 4 is installed at the end of the drive component 3. The adjusting component 4 is used to adjust the switch cover of the bucket component 5 in conjunction with the drive component 3 when driving the bucket component 5 to rotate. The adjusting component 4 includes a sliding main rod 40, which is slidably disposed on the inner wall of one side of the fixed plate 30. A threaded rod 41 is installed at the left end of the sliding main rod 40, and a pull rod 410 is installed at the top of one end of the sliding main rod 40. A rotating disk 42 is sleeved on the outer surface of the threaded rod 41. A sliding block 43 is installed on the inner wall of the rotating disk 42. A pulley set 44 is sleeved on the outer surface of the rotating disk 42. One end of the pulley set 44 is installed with... The device includes a helical gear set 45, with a spur gear 46 mounted on one side. Movable plates 47 are movably mounted on both sides of one end of the sliding main rod 40, and a limit plate 48 is movably mounted on one end of each movable plate 47. The limit plate 48 is installed at the front end of the bucket assembly 5. A sliding insert rod 49 is installed on the right end of the sliding main rod 40. A sliding block 43 is threadedly engaged with the surface of the threaded rod 41. One end of a pull rod 410 is embedded in the inner wall of the rotating disk 42 and slidably connected to it. Under the pull of the pull rod 410, the rotating disk 42 can rotate on the surface of the threaded rod 41. The sliding insert rod 49 is positioned on the limit track. 22. The inner walls of the first arc-shaped rail 23 and the second arc-shaped rail 24 are limited and can slide within the inner walls of the limiting rail 22, the first arc-shaped rail 23 and the second arc-shaped rail 24. The sliding main rod 40 is set at the front end of the disc 20. The sliding main rod 40 of the adjusting component 4 is driven to rotate synchronously by the fixing plate 30 at the front end of the disc 20. At the same time, the sliding insert rod 49 at the right end of the sliding main rod 40 slides inside the limiting rail 22. When the sliding insert rod 49 passes through the upper half of the first arc-shaped rail 23, the sliding insert rod 49 will drive the sliding main rod 40 towards the bucket component 5 according to the curvature of the first arc-shaped rail 23. When the sliding main rod 40 is squeezed towards the bucket assembly 5, it will cause the movable plate 47 to expand to both sides. At this time, the movable plate 47 will push the limiting plate 48 and the side bucket 50 to both sides. At the same time, the side bucket 50 will also drive the side top cover 54 to expand to both sides through the limiting sleeve 53, forming a chamber with the middle bucket 51. At this time, the space of the bucket assembly 5 is expanded. Under the drive of the drive component 3 and in cooperation with the disc mounting component 2, the adjustment component 4 will increase the space of the bucket assembly 5 and squeeze and gather the fuel along the way. The bucket assembly 5 will be expanded and enlarged at the corresponding position to put down the fuel block.

[0046] Furthermore, such as Figure 10As shown, the bucket assembly 5 is installed at the end of the adjusting assembly 4. The bucket assembly 5 is used to scoop up and unload fuel onto the conveyor belt 18 for transmission. The bucket assembly 5 includes a side bucket 50, which is installed on the back of the limiting plate 48. There are two sets of side buckets 50. A middle bucket 51 is slidably and limitedly installed between the two sets of side buckets 50. A roller 52 is installed on the bottom of one side of the side bucket 50. A limiting sleeve 53 is installed on one side of the top of the side bucket 50. A side top cover 54 is slidably and limitedly installed on the inner wall of the limiting sleeve 53. There are two sets of side top covers 54. A middle cover 55 is slidably and limitedly installed between the two sets of side top covers 54. A rack 56 is installed at the bottom of the middle cover 55. One side of the side bucket 50 is installed at the end of the telescopic rod 38. The rack 56 is meshed with the top of the flat gear 46. One side of the side top cover 54 is slidably connected to the inner wall of the limiting sleeve 53. The rotation path of the bucket assembly 5 is located inside the dustproof box 103. When the sliding main rod 40 presses towards the bucket assembly 5, the sliding main rod 40 also drives the tie rod 410 to push the rotating disk 42 to move. During the movement of the rotating disk 42, the inner sliding block 43 slides on the inner side of the threaded rod 41, causing the rotating disk 42 to rotate. The adjusting component 4 drives the flat gear 46 to move the top of the middle cover 55, which is meshed with it, forward. The middle cover 55 drives the side top cover 54, which was just retracted, to move forward simultaneously inside the limiting sleeve 53 and on the top of the side bucket 50 and the middle bucket 51, covering the top of the shrinking side bucket 50 and the middle bucket 51, making the bucket assembly 5 a sealed space to prevent fuel from leaking from both sides during transportation and to avoid fuel spillage during transportation. Since fuel generally has adhesive properties, the fuel is temporarily squeezed into blocks to save space and allow the bucket assembly 5 to scoop up more fuel each time.

[0047] Working principle: First, the control center 102 controls the traveling vehicle 10 to move next to the fuel pile. Then, the infrared scanner 101 is activated to scan the fuel pile. The scanner transmits the image to the control center 102, which then calculates the position and height of the fuel pile. At this point, the traveling vehicle 10 is finely adjusted to align the bucket assembly 5 with the fuel pile. Finally, the drive motor 27 is activated to drive the gear 28 to rotate. The gear 28 drives the meshing gear ring 26 to rotate. The gear ring 26 rotates on the disc 20. The rotation is generated, which drives the gear 4 33 that meshes with it to rotate. When the gear 4 33 rotates, it drives the shaft 31 of the drive assembly 3 to rotate on the inner wall of the fixed plate 30. The gear 3 32 rotates synchronously on the surface of the meshing gear ring 1 25 for limiting. The drive motor 27 causes the drive assembly 3 to drive the bucket assembly 5 to rotate on the back of the disc 20. When the bucket assembly 5 rotates, the main wheel 35 of the limiter 34 rolls in the side rail 21, while the auxiliary wheel 36 rolls on both sides of the edge of the disc 20, which has a limiting effect.

[0048] At this time, the sliding main rod 40 of the adjusting component 4 is driven to rotate synchronously by the fixed plate 30 at the front end of the disc 20. At the same time, the sliding insert rod 49 at the right end of the sliding main rod 40 slides inside the limiting rail 22. When the sliding insert rod 49 passes the upper half of the first arc-shaped rail 23, it will push the sliding main rod 40 towards the bucket assembly 5 according to the curvature of the first arc-shaped rail 23. When the sliding main rod 40 pushes towards the bucket assembly 5, it will cause the movable plate 47 to expand to both sides. The side limit plate 48 and the side bucket 50 are pushed open to both sides. At the same time, the side bucket 50 drives the side top cover 54 to unfold to both sides through the limit sleeve 53, forming a cavity with the middle bucket 51. At this time, the space of the bucket assembly 5 is expanded. At the same time, when the sliding main rod 40 presses towards the bucket assembly 5, the sliding main rod 40 will also drive the tie rod 410 to push the rotating disk 42 to move. During the movement of the rotating disk 42, the inner sliding block 43 slides on the inner side of the threaded rod 41, causing the rotating disk 42 to rotate.

[0049] When the rotating disk 42 rotates, the pulley group 44 installed on the outer surface drives the helical gear group 45 on one side to rotate. The helical gear group 45 drives the spur gear 46 on one side to rotate. The spur gear 46 drives the middle cover 55, which is meshed with it at the top, to move backward. The middle cover 55 drives the side top cover 54, which was just unfolded, to move backward synchronously inside the limiting sleeve 53 and on the top of the side bucket 50 and the middle bucket 51, opening the bucket formed by the side bucket 50 and the middle bucket 51. Because the first arc-shaped rail 23 is set at the lower left of the disk 20, which is also directly opposite the fuel pile, the bucket assembly 5 is unfolded and enlarged at this position and scoops up the fuel. After the bucket assembly 5 scoops up the fuel, the drive assembly 3 also drives the adjustment assembly 4 to leave the position of the first arc-shaped rail 23. At this time, the sliding rod 49 in the adjustment assembly 4, which is used to adjust the opening degree of the bucket assembly 5, returns to the limiting rail 22 at the initial position. When passing through the middle of the first arc-shaped rail 23, the arc is at its maximum, and the space and opening of the bucket assembly 5 are also at their maximum.

[0050] After scooping up the fuel, when passing the lower half of the first arc-shaped rail 23, the sliding rod 49 will drive the sliding main rod 40 to move away from the bucket assembly 5 according to the curvature of the lower half of the first arc-shaped rail 23. When the sliding main rod 40 moves away from the bucket assembly 5, it will drive the movable plate 47 to merge towards the middle. At this time, the movable plate 47 pulls the limiting plate 48 and the side bucket 50 towards the middle and merges them. At the same time, the side bucket 50 drives the side top cover 54 to merge towards the middle through the limiting sleeve 53, reducing the space between the side bucket 50 and the middle bucket 51. At this time, the space of the bucket assembly 5 is reduced. At the same time, when the sliding main rod 40 moves away from the bucket assembly 5, the sliding main rod 40 will also drive the pull rod 410 to pull the rotating disk 42 to move. During the movement of the rotating disk 42, the inner sliding block 43 slides on the inner side of the threaded rod 41, causing the rotating disk 42 to rotate in the opposite direction to the previous movement.

[0051] When the rotating disk 42 rotates, the pulley group 44 installed on the outer surface drives the helical gear group 45 on one side to rotate. The helical gear group 45 drives the spur gear 46 on one side to rotate. The spur gear 46 drives the middle cover 55, which is meshed with it at the top, to move forward. The middle cover 55 drives the side top cover 54, which was just retracted, to move forward synchronously inside the limiting sleeve 53 and on the top of the side bucket 50 and the middle bucket 51, covering the top of the shrinking side bucket 50 and the middle bucket 51, making the bucket assembly 5 a sealed space to prevent fuel from leaking from both sides during transportation and to avoid fuel spillage during transportation. Since fuel generally has adhesive properties, the fuel is temporarily squeezed into blocks to save space and allow the bucket assembly 5 to scoop up more fuel each time.

[0052] Finally, when passing the right side of disc 20, it will pass the second arc-shaped rail 24. At this time, the adjusting component 4 will perform the same action as when passing the first arc-shaped rail 23, unfolding the side bucket 50, middle bucket 51, side top cover 54, and middle cover 55 of the bucket assembly 5, and opening the side top cover 54 and middle cover 55 backward. At this time, the fuel that has been temporarily compressed inside will fall from the air onto the conveyor belt 18 through the opening of the inverted bucket assembly 5. The fuel that was temporarily compressed into blocks by the bucket assembly 5 will fall onto the conveyor belt 18 and proceed to the next step of transmission. At this time, the dust box 103 is used to prevent dust from spreading everywhere, and the internal space of the dust box 103 is narrow. The bottom of the fuel is almost touching the surface of the conveyor belt 18, causing the fuel, which is compressed into blocks, to fall slowly inside the dust box 103 and land intact on the conveyor belt 18 without falling and scattering. This compressed and gathered fuel also saves space during later storage or transportation. (The bucket assembly 5 is initially in a shrunk state, which is convenient for use in small factories. It expands when scooping and lowering, instantly increasing the space. It also compresses and gathers the fuel during transport, turning it into blocks in a short time, making it easier to transport later. The dust box 103 can also be equipped with an external vacuum cleaner to minimize dust generation.)

[0053] When the infrared scanner 101 detects the fuel stack descending to its highest position after being transported, the control center 102 simultaneously starts the drive motor 13 to rotate, driving the gear 14 to rotate the meshing gear disk 15. The gear disk 15 drives the main shaft 12 to rotate, and the main shaft 12 drives the mounting disk 16 to rotate. At this time, the entire disc mounting assembly 2 begins to rotate, driving the first arc rail 23 and the second arc rail 24 to rotate. When the angle position of the first arc rail 23 and the second arc rail 24 changes, the opening and closing positions of the bucket assembly 5 will also change accordingly, so as to follow the descent height when the fuel is taken away. The adjustment component 4 synchronously drives the bucket assembly 5 to make corresponding changes to follow the scooping position of the fuel, so as to achieve the effect of being suitable for fuel at different heights. When the fuel is about to be scooped up and transported and is about to touch the bottom, the roller 52 on the bottom of one side of the side bucket 50 of the bucket assembly 5 will also contact the ground and roll, preventing the bucket assembly 5 from directly scooping the ground and causing damage, thus improving the stability of the bucket assembly 5.
