Description

Technical Field

[0001] This invention belongs to the field of transmission equipment, and in particular to a transmission frame and a transmission machine. Background Technology

[0002] Conveyors are used for conveying and transferring various materials. They typically consist of a frame, on which are mounted drive rollers, reversing rollers, and multiple idler rollers. The conveyor belt is supported by these rollers. The drive rollers, reversing rollers, and idler rollers provide stable support for the conveyor belt, ensuring its stable operation. The frame is usually fixed to the ground, supporting the conveyor belt and other conveying mechanisms. In some special applications, such as open-pit sand mining or ore mining, the ground is often compacted soil rather than hardened ground. When conveying heavy materials such as sand and ore, the frame is prone to settling, and uneven settling is common. When settling is uneven, the frame deforms, and the positional relationship of the drive rollers, reversing rollers, and idler rollers changes. In areas where the conveyor belt has sunk, the support below the belt decreases, potentially increasing the sag of that section and reducing effective tension. In relatively elevated areas, the conveyor belt may be overstretched, leading to rapid wear.

[0003] Patent application CN202411034655.0 discloses a rapid compensation structure for settlement in long-distance belt conveyors. This structure uses adjustable clamping grooves on support columns. When settlement occurs, the height of the lifting sleeve is adjusted, thereby adjusting the height of the connecting frame, and indirectly adjusting the height of each roller on the connecting frame to compensate for the settlement. However, this method cannot monitor the settlement amount in real time, cannot detect settlement promptly, and cannot quickly obtain the adjustment amount. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a conveyor frame and a conveyor that can detect uneven settlement more promptly, determine the adjustment amount quickly, and protect the conveyor belt more effectively.

[0005] To solve the above problems, the technical solution adopted by the present invention is as follows: a conveyor frame, including multiple support frames and multiple pairs of support beams, each pair of support beams is provided with a roller mounting frame, and both ends of the support beams are installed on the support frames through a height adjustment mechanism;

[0006] Reference frames are provided on both sides of the support frame, and a detection housing is provided on the top of the reference frames. A pressure sensor is provided inside the detection housing, and a detection column is provided above the pressure sensor. The lower end of the detection column is connected to the pressure sensor through a first spring. The detection column and the detection housing slide in the vertical direction. The upper end of the detection column extends out of the detection housing and is connected to a horizontal transmission rod. The transmission rod is fixedly connected to the support frame. The pressure sensor is connected to a processor.

[0007] Furthermore, a fixed seat is provided at the top of the support frame, a vertical guide column is provided on the upper surface of the fixed seat, a lifting seat is provided above the fixed seat, the guide column and the lifting seat are slidably engaged, and the height adjustment mechanism is installed between the lifting seat and the fixed seat; the support beam is installed on the lifting seat.

[0008] Furthermore, the support frame includes a horizontal base plate and two vertical threaded columns. The lower end of the threaded column passes through the base plate and is clearance-fitted with the base plate. A limit nut is provided on the threaded column above the base plate. The two threaded columns are connected by an inclined reinforcing rod.

[0009] Furthermore, the lifting seat is provided with a mounting block, and the two ends of the mounting block are provided with rotating shafts, which are tractably mounted on the lifting seat; the side wall of the mounting block is provided with a first mounting hole and a second mounting hole, which are coaxial; the end of the support beam is provided with a cylindrical connector, which is inserted into the first mounting hole or the second mounting hole, and the connector is connected to the mounting block by a connecting screw.

[0010] Furthermore, there are at least two guide columns, each guide column including a threaded section and a smooth shaft section. The threaded section is fixedly connected to the fixed seat, and the outer wall of the threaded section is provided with a support sleeve that is threadedly engaged with the threaded section. The smooth shaft section is slidably engaged with the lifting seat, and the upper end of the support sleeve supports the lower surface of the lifting seat. The height adjustment mechanism is a detachable jack.

[0011] Furthermore, an elastic pad is provided between the support sleeve and the lifting seat. A rectangular through hole is provided horizontally through the fixed seat. A lifting block is provided in the rectangular through hole and slides with the rectangular through hole. At least two lower hanging rings are provided on the upper surface of the lifting block. Multiple hanging ring holes extending to the upper surface of the fixed seat are provided on the top wall of the rectangular through hole. Each lower hanging ring passes through a hanging ring hole. Multiple threaded holes extending to the upper surface of the fixed seat are provided on the top wall of the rectangular through hole. An adjusting screw is provided in each threaded hole and presses the lifting block. An upper hanging ring is provided on the lower surface of the lifting seat above the lower hanging rings. A second spring is connected between the upper and lower hanging rings.

[0012] Furthermore, the detection column includes a lower section and an upper section. A vertical sliding sleeve is fixedly installed inside the detection housing. A vertical sliding groove is provided on the inner wall of the sliding sleeve. A vertical limiting protrusion is provided on the outer wall of the lower section. The lower section passes through the sliding sleeve, and the limiting protrusion slides in cooperation with the sliding groove. The upper end of the lower section is connected to the upper section through a torque sensor, and the torque sensor is connected to the processor.

[0013] A conveyor includes the aforementioned conveyor frame, wherein drive rollers and guide rollers are respectively mounted on roller mounting frames at both ends of the conveyor frame, and a support roller is mounted on the roller mounting frame between the drive rollers and the guide rollers, and a conveyor belt is mounted on the drive rollers and the guide rollers.

[0014] Furthermore, a cleaning mechanism is provided on one side of both the drive roller and the steering roller. The cleaning mechanism includes a cleaning housing, within which a vertical shot peening plate is installed. A shot peening channel runs vertically through the shot peening plate and is tangent to either the drive roller or the steering roller. A mixing chamber is connected to the lower end of the shot peening channel, and an air supply mechanism is connected to the bottom of the mixing chamber. A shot collection trough is provided on one side of the top of the shot peening plate, containing elastic shot. The bottom of the shot collection trough is connected to the mixing chamber via a discharge port. A discharge shaft is installed in the discharge port, connected to a discharge motor. A storage trough is provided on the outer wall of the discharge shaft. An exhaust and dust removal mechanism is connected to the cleaning housing above the shot collection trough.

[0015] The beneficial effects of this invention are as follows: Currently, there are various monitoring devices capable of automatically detecting frame settlement, such as hydrostatic levels, tilt sensors, laser rangefinders, three-dimensional scanning devices, and settlement deformation strain sensors. However, due to the harsh environment of open-pit sand mining and other mining sites, with a large amount of dust at the transportation site and the influence of various weather conditions such as rain and sunlight, these traditional monitoring devices are difficult to operate effectively for extended periods and require frequent maintenance. Furthermore, during the operation of the conveyor belt, static electricity is generated due to friction between the conveyor belt and the rollers, and between the conveyor belt and the dust. If the monitoring device is directly installed on the frame, electrostatic discharge may interfere with or even damage sensitive components.

[0016] In this invention, the reference frame does not bear external loads, so it essentially does not settle; that is, the reference frame remains fixed even when the support frame settles. When the support frame settles, the transmission rod settles synchronously with the support frame, which in turn drives the detection column downwards. The first spring is compressed, increasing its elastic force. The pressure sensor detects the change in elastic force and calculates the spring compression based on this change, thus obtaining the settlement amount. When the settlement amount exceeds a set value, the processor can promptly issue an alarm message to facilitate timely handling of the settlement.

[0017] This invention employs a pressure sensor combined with a processor to monitor the settlement of each support frame. This allows for real-time monitoring of settlement, timely detection, and prompt adjustments. The pressure sensor and processor are fundamental components, small in size, and low in cost. Installing the pressure sensor and processor inside the detection housing protects them from harsh external environments and static electricity, ensuring long-term effective operation of the detection components without requiring frequent maintenance.

Detailed Implementation

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] The transmission rack of the present invention, such as Figures 1 to 5As shown, it includes multiple support frames 1 and multiple pairs of support beams 2. Each pair of support beams 2 is equipped with a roller mounting frame 3. Both ends of the support beams 2 are mounted on the support frames 1 through a height adjustment mechanism 5.

[0029] Reference frames 4 are provided on both sides of the support frame 1. A detection housing 41 is provided on the top of the reference frame 4. A pressure sensor 42 is provided inside the detection housing 41. A detection column 43 is provided above the pressure sensor 42. The lower end of the detection column 43 is connected to the pressure sensor 42 through a first spring 44. The detection column 43 and the detection housing 41 slide in the vertical direction. The upper end of the detection column 43 extends out of the detection housing 41 and is connected to a horizontal transmission rod 47. The transmission rod 47 is fixedly connected to the support frame 1. The pressure sensor 42 is connected to a processor 48.

[0030] The reference frame 4 is set on the ground nearby. Specifically, the reference frame 4 can be a vertical column with its lower end driven into the soil at least 50cm to ensure its stability. To prevent the reference frame 4 from changing position when the support frame 1 settles, the reference frame 4 can be set at a position far from the support frame 1, and a crossbeam can be set on the top of the support frame 1. The detection housing 41 is installed on the crossbeam to avoid an excessive distance between the detection housing 41 and the support frame 1. The reference frame 4 does not bear external loads, so it will basically not settle. The position of the reference frame 4 can be considered fixed. As long as the distance that the support frame 1 moves downward relative to the reference frame 4 is detected, the settlement of the support frame 1 can be obtained.

[0031] The detection housing 41 can be circular or square, and is entirely enclosed. It has an openable and closable access door on its side wall. During normal operation, the detection housing 41 is in a relatively sealed state to prevent external dust from entering. A through-hole is provided at the top of the detection housing 41, and the detection post 43 is located in and slides within the through-hole. The first spring 44 is in a slightly compressed state, exhibiting elasticity. The pressure sensor 42 can detect this elasticity and transmit the detection signal to the processor 48. The transmission rod 47 is made of a high-rigidity rod, such as angle steel.

[0032] The transmission rod 47, the support frame 1, and the detection column 43 are integrated. When the support frame 1 sinks, it will drive the transmission rod 47 to move downward, which in turn drives the detection column 43 to move downward. The detection column 43 further compresses the first spring 44, increasing the elastic force of the first spring 44. The pressure sensor 42 can detect the change in the elastic force of the first spring 44, and the processor 48 calculates the compression of the first spring 44 based on the change in the elastic force and the elastic modulus. The compression of the first spring 44 is equal to the sinking of the support frame 1.

[0033] By setting the reference frame 4 and detection structure on both sides of each support frame 1, the settlement on both sides of each support frame 1 can be monitored in real time. When the settlement exceeds the set threshold, the processor 48 issues a notification or alarm. At the same time, the adjustment amount at both ends of each support beam 2 is determined based on the settlement of each support frame 1. Then, the management personnel adjust the height of both ends of each support beam 2 through the height adjustment mechanism 5 to overcome the deformation caused by uneven settlement of the support beam 2 and ensure that each support beam 2 is in a straight line, thereby providing stable support for the conveyor belt. Specifically, in areas with large settlement, the height adjustment mechanism 5 drives the end of the support beam 2 to move upward; in areas with small settlement, the height adjustment mechanism 5 drives the end of the support beam 2 to move downward appropriately to reduce the adjustment amount.

[0034] To facilitate stable adjustment of the height at both ends of the support beam 2, a fixed seat 15 is provided on the top of the support frame 1. The fixed seat 15 is fixed to the top of the support frame 1, and a vertical guide column 17 is provided on the upper surface of the fixed seat 15. A lifting seat 16 is provided above the fixed seat 15. The guide column 17 and the lifting seat 16 slide in the vertical direction. The height adjustment mechanism 5 is installed between the lifting seat 16 and the fixed seat 15. The support beam 2 is installed on the lifting seat 16, and the ends of two adjacent support beams 2 are installed on the same lifting seat 16. Therefore, the height of the ends of two adjacent support beams 2 can be adjusted simultaneously by adjusting the height of the lifting seat 16. The guide column 17 serves as a guide and auxiliary positioning to ensure that the lifting seat 16 can be raised and lowered stably.

[0035] In many cases, conveyor belts need to be tilted to transport materials from a low position to a high position. In order to facilitate the adjustment of the tilt angle of the conveyor belt to adapt to more application scenarios, the support frame 1 of the present invention includes a horizontal base plate 11 and two vertical threaded columns 12. The lower end of the threaded column 12 passes through the base plate 11 and is clearance-fitted with the base plate 11. A limit nut 13 is provided on the threaded column 12 above the base plate 11. The two threaded columns 12 are connected by an inclined reinforcing rod 14.

[0036] During installation, first level and compact the ground, then lay the base plate 11 flat on the ground. The lower end of the threaded post 12 can be set as a pointed end. After passing through the base plate 11, the threaded post 12 is driven into the soil to a depth greater than 1m to ensure stability. Then, rotate the limiting nut 13 to press the limiting nut 13 tightly against the base plate 11. Next, a reinforcing rod 14 is installed between the two threaded posts 12. The reinforcing rod 14 can be bolted to the threaded post 12. Specifically, an adjusting sleeve that is threaded to the threaded post 12 can be fitted onto the threaded post 12. The two ends of the reinforcing rod 14 are bolted to the outer wall of the adjusting sleeve, allowing for flexible adjustment of the height of the reinforcing rod 14. When it is necessary to adjust the tilt angle of the conveyor belt, simply replace the threaded post 12 with one of different lengths.

[0037] The end of the support beam 2 can be installed on the lifting seat 16 by bolts, etc. When the tilt angle of the conveyor belt is adjusted, the tilt angle of the support beam 2 also changes. However, the lifting seat 16 can only move up and down, but cannot rotate to adapt to the change in the tilt angle of the support beam 2. If the support beam 2 is directly hinged to the lifting seat 16, it cannot be guaranteed that two adjacent support beams 2 will be in a straight line after installation.

[0038] In this invention, a mounting block 18 is provided on the lifting seat 16, and a rotating shaft 19 is provided at both ends of the mounting block 18. The rotating shaft 19 is tractably mounted on the lifting seat 16. A first mounting hole and a second mounting hole are provided on the side wall of the mounting block 18. The first mounting hole and the second mounting hole are coaxial. A cylindrical connector 110 is provided at the end of the support beam 2. The connector 110 is inserted into the first mounting hole or the second mounting hole, and the connector 110 is connected to the mounting block 18 by a connecting screw.

[0039] When adjusting the tilt angle of the support beam 2, rotate the mounting block 18 until the angle between the first mounting hole and the second mounting hole and the horizontal plane is the same as the tilt angle of the support beam 2. After installing the support beam 2, since the first mounting hole and the second mounting hole are coaxial, the coaxiality of the two adjacent connectors 110 is ensured, thus ensuring that the two adjacent support beams 2 are on the same straight line. To facilitate the insertion of the connector 110 into the first mounting hole and the second mounting hole, the mounting block 18 can be divided into a detachable first mounting block and a second mounting block. Each of the first mounting block and the second mounting block contains half of the first mounting hole and the second mounting hole. After the first mounting block and the second mounting block are assembled, they form a complete first mounting hole and a second mounting hole. After the first mounting block and the second mounting block are separated, the first mounting hole and the second mounting hole become a groove with a semi-circular cross-section, allowing the connector 110 to be quickly inserted into the groove, and then the first mounting block and the second mounting block are connected as one unit.

[0040] There are various commonly used height adjustment mechanisms, such as automatically operating hydraulic cylinders and motor-driven screw mechanisms. When the transmission machine is long, a large number of height adjustment mechanisms are required, resulting in high equipment costs and energy consumption during operation, further increasing costs. In harsh working environments, the wiring and equipment are easily damaged. To save equipment costs and achieve height adjustment of the lifting seat 16 with minimal effort, this invention uses at least two guide columns 17. Each guide column 17 includes a threaded section and a smooth shaft section. The threaded section is fixedly connected to the fixed seat 15, and the outer wall of the threaded section is provided with a support sleeve 111 that is threadedly engaged with the threaded section. The smooth shaft section is slidably engaged with the lifting seat 16, and the upper end of the support sleeve 111 supports the lower surface of the lifting seat 16. The height adjustment mechanism 5 is a detachable jack.

[0041] When the conveyor is operating normally, the support sleeve 111 supports the lifting seat 16, eliminating the need for jacks and numerous height adjustment mechanisms 5. To adjust the height of the lifting seat 16, move the jack to the fixed seat 15 and hold the lifting seat 16 in place. To increase the height of the lifting seat 16, use the jack to lift it upwards, then rotate the support sleeve 111 until it moves upwards and makes tight contact with the lifting seat 16. Then retract the jack and remove it. To decrease the height of the lifting seat 16, simply rotate the support sleeve 111 downwards by the required adjustment distance, then retract the jack, lower the lifting seat 16 to the support sleeve 111, and remove the jack.

[0042] When the lifting seat 16 is supported solely by the support sleeve 111, the lifting seat 16 is prone to vibration and jumping. To improve the stability of the lifting seat 16 and reduce vibration to extend the service life of components such as the support sleeve 111, this invention provides an elastic pad 112 between the support sleeve 111 and the lifting seat 16. The elastic pad 112 can be made of common materials such as nitrile rubber, which can absorb loads and has a certain vibration damping capacity. A rectangular through hole is provided horizontally through the fixed seat 15. A lifting block 113 is provided in the rectangular through hole and slides in accordance with the rectangular through hole. The lifting block 113 can slide both horizontally and vertically. At least two lower hanging rings 114 are provided on the upper surface of the lifting block 113. The top wall of the rectangular through hole is provided with multiple hanging ring holes extending to the upper surface of the fixed seat 15, and each lower hanging ring 114 passes through a hanging ring hole. The top wall of the rectangular through hole is provided with multiple threaded holes extending to the upper surface of the fixed seat 15. Each threaded hole is provided with an adjusting screw 115, and the lower end of the adjusting screw 115 presses against the lifting block 113. The lower surface of the lifting seat 16 above the lower hanging ring 114 is provided with an upper hanging ring 116, and a second spring 117 is connected between the upper hanging ring 116 and the lower hanging ring 114.

[0043] After adjusting the height of the lifting seat 16, move the lifting block 113 to the top of the rectangular through hole. Then, attach the upper end of the second spring 117 to the upper hanging ring 116 and the lower end to the lower hanging ring 114. Next, release the lifting block 113 and rotate the adjusting screw 115, causing it to move downwards. The adjusting screw 115 pushes the lifting block 113 downwards, extending the second spring 117 and gradually increasing its elastic force. When the extension of the second spring 117 reaches the required amount, stop rotating the adjusting screw 115. At this time, the second spring 117 tightens the lifting seat 16, improving its stability and preventing it from jumping up and down significantly. Simultaneously, the vibration of the lifting seat 16 can be buffered by the second spring 117.

[0044] When the conveyor frame is installed on a slope, tilting settlement may occur, meaning the conveyor frame tilts and slides downwards, changing not only its vertical position but also its horizontal position. To simultaneously monitor the horizontal sliding trend of the support frame 1, the detection column 43 of this invention includes a lower section and an upper section. A vertical sliding sleeve 49 is fixedly installed inside the detection housing 41, and a vertical sliding groove is provided on the inner wall of the sliding sleeve 49. A vertical limiting protrusion 410 is provided on the outer wall of the lower section. The lower section passes through the sliding sleeve 49, and the limiting protrusion 410 slides in conjunction with the sliding groove, allowing the lower section to move only up and down without rotation. The upper end of the lower section is connected to the upper section via a torque sensor 46, which is connected to a processor 48. A transmission rod 47 is fixedly connected to the upper section.

[0045] When the support frame 1 tends to slide horizontally, the transmission rod 47 tends to rotate, thereby applying a torque to the upper section of the detection column 43. This torque is transmitted to the torque sensor 46 and can be detected by it. The torque sensor 46 then transmits the detection result to the processor 48. The more severe the horizontal sliding tendency of the support frame 1, the greater the torque detected by the torque sensor 46. When the torque value reaches a set value, it indicates a high risk of horizontal sliding of the frame. At this time, a notification or alarm can be issued to reinforce the conveyor belt frame. This invention can detect the risk of sliding in the early stages of horizontal sliding of the frame, avoiding damage to the equipment when the frame slides significantly. In addition, the torque sensor 46 and the pressure sensor 42 are both integrated into the detection housing 41, which is not affected by external dust, resulting in a simple overall structure and low implementation cost.

[0046] The transmitter of the present invention, such as Figures 6 to 8 As shown, the conveyor frame includes a drive roller 100 and a guide roller 200 respectively mounted on roller mounting frames 3 at both ends of the conveyor frame. The drive roller 100 is connected to a drive motor to drive its rotation. A support roller 300 is mounted on the roller mounting frame 3 between the drive roller 100 and the guide roller 200, and a conveyor belt 400 is mounted on the drive roller 100 and the guide roller 200. The structure of the roller mounting frame 3 and the mounting method of the drive roller 100, guide roller 200, and support roller 300 can be achieved using existing technology.

[0047] During the transport of sand, gravel, and ore, moisture-containing clay, concentrate powder, and other substances easily adhere to the surfaces of the drive roller 100 and the guide roller 200, forming localized protrusions. This causes the conveyor belt 400 to experience periodic and severe vibrations during operation. To keep the drive roller 100 and the guide roller 200 clean, a cleaning mechanism can be installed. Traditional cleaning mechanisms are usually scrapers. While scrapers can effectively remove various substances adhering to the surfaces of the drive roller 100 and the guide roller 200, they are prone to leaving scratches, leading to rapid wear of the drive roller 100 and the guide roller 200 and affecting their lifespan.

[0048] In this invention, a cleaning mechanism is provided on one side of both the drive roller 100 and the steering roller 200. The cleaning mechanism includes a cleaning housing 101, which can be mounted on the support beam 2, the support frame 1, or the roller mounting frame 3. A cleaning window is provided on one side of the cleaning housing 101, and the cleaning window is clearance-fitted with the drive roller 100 and the steering roller 200 to prevent wear on the drive roller 100 and the steering roller 200. A vertical shot peening plate 102 is provided inside the cleaning housing 101, and a shot peening channel 103 is provided inside the shot peening plate 102, which is a rectangular channel with the same length as the drive roller 100. The shot peening channel 103 is tangent to the drive roller 100 or the steering roller 200, that is, the direction of movement of the shot ejected from the shot peening channel 103 is perpendicular to the radial direction of the drive roller 100 or the steering roller 200. The lower end of the shot peening channel 103 is connected to a mixing chamber 104, and the bottom of the mixing chamber 104 is connected to an air supply mechanism 105. The air supply mechanism 105 can be an air pump, which is connected to the mixing chamber 104 through an air distribution mechanism. The air pump delivers outside air to the air distribution mechanism, and the air is dispersed by the air distribution mechanism and then evenly enters the mixing chamber 104. A shot collection groove 106 is provided on one side of the top of the shot peening plate 102. The shot collection groove 106 contains elastic shot material, which is made of lightweight elastic small balls, such as polypropylene balls. The bottom of the shot collection groove 106 is connected to the mixing chamber 104 through a discharge port. A discharge shaft 107 is provided in the discharge port, and a discharge motor 108 is connected to the discharge shaft 107. A storage trough 109 is provided on the outer wall of the discharge shaft 107. The width of the storage trough 109 is larger than the diameter of the elastic shot material to ensure that the elastic shot material can enter the storage trough 109. The cleaning housing 101 above the shot collection tank 106 is connected to an exhaust and dust removal mechanism 1010, which can be a common dust removal mechanism such as a dust collector bag.

[0049] When the cleaning mechanism is running, the air supply mechanism 105 introduces high-speed airflow into the mixing chamber 104. At the same time, the feeding motor 108 drives the feeding shaft 107 to rotate at a constant speed. The elastic shot in the shot collection trough 106 enters the storage trough 109. When the storage trough 109 rotates with the feeding shaft 107 to the lower part of the feeding shaft 107, the opening of the storage trough 109 faces downward, and the elastic shot in the storage trough 109 falls into the mixing chamber 104. The high-speed airflow carries the elastic shot into the shot blasting channel 103, and then sprays it out from the upper port of the shot blasting channel 103. The elastic shot impacts the outer wall of the drive roller 100 and the steering roller 200, causing the debris adhering to the outer wall of the drive roller 100 and the steering roller 200 to detach. The detached debris enters the exhaust dust removal mechanism 1010 with the airflow. After being dusted by the exhaust dust removal mechanism 1010, the air is discharged, and the solid impurities remain in the exhaust dust removal mechanism 1010. After the elastic shot impacts the drive roller 100 and the guide roller 200, it falls into the shot collection trough 106. To prevent the elastic shot from entering the exhaust and dust removal mechanism 1010, an intercepting net can be installed at the inlet of the exhaust and dust removal mechanism 1010, with the mesh size of the net smaller than the diameter of the elastic shot. Depending on the surrounding environment, the drive roller 100 and the guide roller 200 can be cleaned periodically.

[0050] In this invention, elastic pellets impact the drive roller 100 and the steering roller 200. Under the action of mechanical impact, vibration, and friction, debris on the surfaces of the drive roller 100 and the steering roller 200 can be dislodged. During the impact, the elastic pellets make instantaneous contact with the drive roller 100 and the steering roller 200, preventing wear on them. Furthermore, if the direction of movement of the elastic pellets during impact is consistent with the radial direction of the drive roller 100 and the steering roller 200, some stubborn debris may be further compacted and difficult to remove. In this invention, the direction of movement of the elastic pellets is perpendicular to the radial direction of the drive roller 100 and the steering roller 200. The elastic pellets apply shear force to the debris on the surfaces of the drive roller 100 and the steering roller 200, which can more effectively peel off the debris while preventing it from being compacted, thus ensuring a cleaning effect.
