Description

Technical Field

[0001] This invention relates to the field of intelligent agricultural power machinery technology, specifically to an intelligent sensing self-starting interlocking wheeled harvester. Background Technology

[0002] The manufacturing of intelligent agricultural power machinery and supporting implements is a core area for the transformation and upgrading of the modern agricultural equipment industry towards high-end, intelligent, and green development. In the field of agricultural product harvesting, intelligent sensing wheeled harvesters have become key equipment for improving operational efficiency and safety. These harvesters integrate environmental perception sensors (such as vision and radar) and automatic control systems into traditional harvesters, aiming to achieve automatic identification and emergency response to personnel, animals, or obstacles in front of the operation, thereby reducing safety accidents.

[0003] Existing intelligent sensing wheeled harvesters include a drive module, a harvesting module, and a sensing module. The drive module and the harvesting module are connected by a connector, and the connector and the sensing module are connected by a control system. When the sensing module detects an abnormality, the control system immediately controls the connector to cut off the power transmitted from the drive module to the harvesting module.

[0004] Existing intelligent sensor-driven wheeled harvesters typically use electromagnetic clutches, electro-hydraulic clutches, or direct control of the engine's power output as their components. When these components operate, they can separate the mechanical connection between the drive module and the harvesting module (cutter, drum, etc.). However, after the power is cut off, the drive torque disappears, but the kinetic energy stored in the high-speed rotating harvesting module due to its huge rotational inertia is not actively eliminated. The cutter and other components will continue to rotate for a period of time (several seconds to tens of seconds) under pure inertia. This period from the power being cut off to the complete stop due to the exhaustion of inertia forms a "continuous danger window." During this period, people or animals are still exposed to the high-speed rotating cutter, and the risk of accident is not immediately eliminated by the power being cut off. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent sensor-activated self-starting interlocking wheeled harvester to solve the problems mentioned in the background art.

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

[0007] A smart sensor-activated self-starting interlocking wheeled harvester includes a frame, a harvesting module rotatably mounted at one end of the frame in the direction of travel, and a mounting frame rotatably connected to the harvesting module mounted on the frame; a sensor module is mounted on the mounting frame. It also includes a rotating shaft rotatably mounted on the mounting frame, the rotating shaft being connected to the harvesting module, a driven disk being mounted on the rotating shaft, and multiple sets of driven tooth blocks being mounted on the driven disk at equal intervals along its circumference. A drive shaft and a power shaft are rotatably mounted on the mounting frame, the power shaft being connected to the output end of the drive module, and the power shaft and the drive shaft being connected by a speed changer, the speed changer being used to change the transmission ratio between the power shaft and the drive shaft. A drive disc is slidably fitted onto the drive shaft, and multiple sets of drive teeth blocks are installed on the drive disc at equal intervals along its circumference. The drive teeth blocks mesh with the driven teeth blocks when they are in contact. The mounting bracket is equipped with mutually cooperating joints and braking components; When the sensing module detects an abnormal environment in the direction of travel of the vehicle frame, the combined component can drive the active disc away from the driven disc, and the braking component can intermittently apply radial pressure to the shaft to cut off the power source of the harvesting module and perform a deceleration action on it.

[0008] As described above, the intelligent sensor-driven self-starting interlocking wheeled harvester has the following features: a motor is mounted on the mounting frame; a lead screw is mounted on the output end of the motor; a lifting plate is provided on the mounting frame and threadedly connected to the lead screw; when the sensing module detects an abnormality in the environmental conditions of the vehicle frame's travel direction, it can control the motor to move, thereby driving the lifting plate to rise, which in turn drives the connecting component, the brake component, and the transmission component to move.

[0009] The intelligent sensor-activated self-starting interlocking wheeled harvester described above includes: a fixed sleeve sleeved on the drive shaft, with a compression ring slidably fitted inside the fixed sleeve; a separation spring sleeved on the drive disc; a buffer spring sleeved on the drive shaft; the two ends of the separation spring abutting against the drive disc and the fixed sleeve respectively, and the two ends of the buffer spring abutting against the drive disc and the compression ring respectively; and a compression wedge block mounted on the lifting plate, which slidably fits against the fixed sleeve and compresses against the compression ring.

[0010] As described above, in the intelligent sensor-activated self-starting interlocking wheeled harvester: during the process of the lifting plate driving the extrusion wedge to rise, the elastic force of the separation spring can drive the driving disc away from the driven disc; the buffer spring has the same stiffness coefficient as the separation spring.

[0011] The intelligent sensor-activated self-starting interlocking wheeled harvester described above: the braking component includes a fixed block mounted on the mounting frame; the fixed block rotatably engages with the rotating shaft; a fixed plate is mounted on the mounting frame; the mounting frame is provided with a lifting frame, a return spring, and a sliding wedge block slidably engaged; a triangular block that presses against the sliding wedge block and a brake block that slidably engages with the fixed plate are mounted on the lifting frame; a mounting plate is mounted on the lifting plate; multiple sets of fixed wedge blocks that engage with the sliding wedge block are mounted on the mounting plate; the two ends of the return spring abut against the fixed plate and the lifting frame, respectively.

[0012] As described above, the intelligent sensor-activated self-starting interlocking wheeled harvester has the following features: the sliding wedge is inclined on both its upper and lower surfaces; during the rising or falling of the mounting plate, multiple sets of fixed wedges can alternately press and engage with the sliding wedge.

[0013] The intelligent sensor-activated self-starting interlocking wheeled harvester described above: the transmission component includes a linkage shaft and an adjustment shaft rotatably mounted on the mounting frame, the linkage shaft is provided with a groove group, and the lifting plate is provided with an adjustment protrusion that slides and engages with the groove group; the adjustment shaft and the linkage shaft are connected by a bevel gear set.

[0014] The intelligent sensor-activated self-starting interlocking wheeled harvester described above: the trough group includes an ascending straight trough, a deceleration sloping trough, a descending straight trough, and a speed-increasing sloping trough connected sequentially at their ends; wherein when the adjusting protrusion cooperates with the deceleration sloping trough or the speed-increasing sloping trough, it can drive the adjusting shaft to rotate, thereby reducing or increasing the speed of the drive shaft.

[0015] As described above, the intelligent sensor-activated self-starting interlocking wheeled harvester includes: a transmission component further comprising multiple sets of driving half-pulleys slidably fitted onto the power shaft and symmetrically arranged; multiple sets of driven half-pulleys slidably fitted onto the drive shaft; the multiple sets of driving half-pulleys and the multiple sets of driven half-pulleys are connected by steel belts; multiple sets of driving sleeves rotatably connected to the driving half-pulleys and driven sleeves rotatably connected to the driven half-pulleys are sleeved on the adjusting shaft; multiple sets of symmetrically arranged driven inclined grooves and multiple sets of symmetrically arranged driving inclined grooves are provided on the adjusting shaft; driving protrusions slidably fitted onto the driving inclined grooves are installed on the driving sleeves; driven protrusions slidably fitted onto the driven inclined grooves are installed on the driven sleeves.

[0016] As described above, in a wheeled harvester with intelligent induction self-starting interlocking: when the combined component drives the driving disc to approach the driven disc, after the driving tooth block meshes with the driven tooth block, the adjusting protrusion slides in the descending straight groove toward the speed-increasing inclined groove.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. After receiving the instruction from the sensing module, the assembly can drive the active disk to move away from the driven disk axially, causing the active tooth block and the driven tooth block to disengage instantly, thereby completely cutting off the power source transmitted to the harvesting module. This fast and reliable hard disconnection fundamentally eliminates the risk of personal injury or equipment damage that may be caused by continuous power output. 2. The harvesting module, whose power has been cut off, is flexibly decelerated by the braking components. Its intermittent radial compression braking method uses fixed wedges to push the brake blocks in a rhythmic "brake-release-re-brake" motion on the rotating shaft. This can continuously and smoothly consume the huge rotational inertial energy of the harvesting module, allowing it to decelerate smoothly to a stop. This effectively avoids the mechanical impact, structural stress concentration, or component damage caused by instantaneous rigid braking. At the same time, it avoids brake overheating and improves the controllability and safety of the braking process. 3. When the connecting parts move and the power is cut off, the transmission components automatically adjust the transmission ratio and actively reduce the speed of the driving disc. When the risk is eliminated and the connecting parts need to reconnect the power, the transmission components can ensure that the driving disc approaches and meshes with the driven disc smoothly at a lower speed. After full engagement, it automatically returns to the working speed, which effectively reduces the impact and risk of gear breakage during gear meshing, protects the transmission system, and extends the service life of the equipment. 4. Through the cooperation of sensing modules, connecting components, braking components, and transmission components, intelligent safety control of the entire process from risk perception and rapid response to smooth recovery is achieved. This not only effectively prevents operational accidents and ensures the safety of personnel and machines, but also significantly reduces the failure rate and wear of the equipment itself through flexible force and motion control, improving the reliability and overall efficiency of the system, demonstrating a high degree of intelligence and engineering practicality.

Detailed Implementation

[0033] 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.

[0034] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0035] Please see Figures 1-14 As an embodiment of the present invention, the intelligent sensing self-starting interlocking wheeled harvester includes a frame 1, a harvesting module 2 is rotatably mounted on one end of the frame 1 in the direction of travel, a mounting frame 3 is mounted on the frame 1 and rotatably connected to the harvesting module 2, and a sensing module 4 is mounted on the mounting frame 3. It also includes a rotating shaft 20 rotatably mounted on the mounting frame 3, the rotating shaft 20 being connected to the harvesting module 2, a driven disk 15 mounted on the rotating shaft 20, and multiple sets of driven tooth blocks 1501 equidistantly arranged along its circumference mounted on the driven disk 15. A drive shaft 7 and a power shaft 5 are rotatably mounted on the mounting frame 3, the power shaft 5 being connected to the output end of the drive module, and the power shaft 5 and the drive shaft 7 being connected by a speed changer, the speed changer being used to change the transmission ratio between the power shaft 5 and the drive shaft 7. A drive disc 14 is slidably fitted on the drive shaft 5. Multiple sets of drive teeth 1401 are installed on the drive disc 14 and are equidistantly arranged along its circumference. When the drive teeth 1401 and the driven teeth 1501 are in contact, they mesh. The mounting bracket 3 is equipped with mutually cooperating joints and braking components; When the sensing module 4 detects an abnormal environment in the direction of travel of the frame 1, the combined component can drive the active disc 14 away from the driven disc 15, and the braking component can intermittently apply radial pressure to the rotating shaft 20 to cut off the power source of the harvesting module 2 and perform deceleration action on it.

[0036] In this embodiment, in the initial state, the active disk 14 and the driven disk 15 are in contact, and the active tooth block 1401 and the driven tooth block 1501 are meshed with each other. When the drive module drives the power shaft 5 to rotate, it can drive the active shaft 7 to rotate through the speed change component, thereby driving the driven disk 15 to rotate through the active disk 14, so as to drive the harvesting module 2 to rotate through the rotating shaft 20. At this time, the transmission ratio between the power shaft 5 and the active shaft 7 is large, and the harvesting module 2 can rotate at high speed to reduce the harvesting difficulty.

[0037] The sensing module 4 senses the ambient conditions in real time along the direction of travel of the frame 1. When it senses an abnormality in the environment ahead, such as a person, animal, or obstacle, the sensing module 4 controls the movement of the connecting parts to quickly drive the drive disc 14 along the axis of the drive shaft 7 towards the driven disc 15. This causes the drive gear block 1401 and the driven gear block 1501 to disengage, thereby cutting off the power source of the rotating shaft 20 and preventing accidental injury or damage to the harvesting module 2. At the same time, the braking components intermittently apply radial compression to the rotating shaft 20 to gradually eliminate the inertial rotation of the harvesting module 2. This can prevent structural damage due to instantaneous braking and also prevent accidents caused by the rotating harvesting module 2.

[0038] Once the environment meets the harvesting requirements, the sensing module 4 will control the movement of the connecting parts and the braking parts, thereby releasing the radial compression on the rotating shaft 20 and re-engaging the active tooth block 1401 with the driven tooth block 1501, thus resuming production.

[0039] As a further embodiment of the present invention, a motor 28 is mounted on the mounting frame 3; a lead screw 29 is mounted on the output end of the motor 28; a lifting plate 25 is provided on the mounting frame 3 and threadedly connected to the lead screw 29; when the sensing module 4 senses an abnormality in the environmental state of the vehicle frame 1 in the direction of travel, it can control the motor 28 to move, thereby driving the lifting plate 25 to rise, thereby driving the joint, the brake and the transmission components to move.

[0040] In this embodiment, the sensing module 4 senses the ambient conditions in the direction of travel of the frame 1 in real time. When an abnormality is detected in the environment ahead, the sensing module 4 controls the motor 28 to rotate, thereby driving the lead screw 29 to rotate. This, in turn, drives the lifting plate 25 to rise through the threaded engagement. During this process, the connecting component separates the driving disc 14 from the driven disc 15 and applies intermittent radial pressure to the rotating shaft 20 through the brake component, thereby preventing accidents and protecting both personal safety and the device from damage. After the environment recovers, the motor 28 reverses its movement, thereby driving the lifting plate 25 to descend, so as to restore the power of the harvesting module 2 through the connecting component and the brake component.

[0041] As a further embodiment of the present invention, the assembly includes a fixed sleeve 13 sleeved on the drive shaft 7, with a compression ring 18 slidably fitted inside the fixed sleeve 13; a separation spring 16 sleeved on the drive disc 14; a buffer spring 17 sleeved on the drive shaft 7; the two ends of the separation spring 16 abut against the drive disc 14 and the fixed sleeve 13 respectively, and the two ends of the buffer spring 17 abut against the drive disc 14 and the compression ring 18 respectively; and a compression wedge 27 is installed on the lifting plate 25, which slidably fits into the fixed sleeve 13 and compresses against the compression ring 18.

[0042] As a further embodiment of the present invention, during the process of the lifting plate 25 driving the squeezing wedge 27 to rise, the elastic force of the separation spring 16 can drive the active plate 14 away from the driven plate 15; the buffer spring 17 has the same stiffness coefficient as the separation spring 16.

[0043] In this embodiment, in the initial state, the lifting plate 25 is in a relatively low position. In this position, the squeezing wedge 27 squeezes the squeezing ring 18, so that the buffer spring 17 and the separation spring 16 are both in a compressed state; and the active plate 14 is in contact with the driven plate 15, so that the drive module can drive the harvesting module 2 to move.

[0044] When the sensing module 4 senses the ambient conditions in the direction of travel of the frame 1 in real time, and detects an abnormality in the environment ahead, the lifting plate 25 rises, which in turn causes the squeezing wedge block 27 to rise. At this time, under the elastic force of the separation spring 16, the driving disc 14 will move away from the driven disc 15 along the axial direction of the driving shaft 7, causing the driving tooth block 1401 and the driven tooth block 1501 to disengage. Under the elastic force of the buffer spring 17, the squeezing ring 18 will move away from the driving disc 14 along the axial direction of the driving shaft 7, thereby disconnecting the power source of the harvesting module 2 and reducing the probability of dangerous accidents.

[0045] After the environment is restored, the lifting plate 25 moves downward and drives the squeezing wedge 27 to move synchronously. At this time, the squeezing wedge 27 squeezes the squeezing ring 18, causing it to approach the driving disc 14 along the drive shaft 7 axis and compress the buffer spring 17. At the same time, it drives the driving disc 14 to approach the driven disc 15, causing the separation spring 16 to be compressed. During this process, when the active tooth block 1401 and the driven tooth block 1501 mesh, the impact force can be buffered by the elasticity of the buffer spring 17 and the separation spring 16, thus preventing damage to the device structure. After the active disk 14 and the driven disk 15 are fully engaged, the resistance to their separation is relatively large, which can meet the harvesting requirements. When the rotation of the harvesting module 2 is greatly hindered (such as excessive grain entanglement or encountering obstacles that are difficult to sense), the difficulty of rotating the driven disk 15 increases instantly. At this time, through the squeezing action of the active tooth block 1401 and the driven tooth block 1501, the active disk 14 can be moved away from the driven disk 15, and the buffer spring 17 can be compressed to cut off the power transmission. This effectively prevents the power system from being overloaded and damaged, further improving the reliability and safety of the equipment.

[0046] As a further embodiment of the present invention, the brake component includes a fixing block 19 mounted on the mounting bracket 3; the fixing block 19 is rotatably engaged with the rotating shaft 20; a fixing plate 21 is mounted on the mounting bracket 3; a lifting frame 22 and a return spring 23 are provided on the mounting bracket 3, and a sliding wedge 24 is slidably engaged therewith; a triangular block 2202 that presses against the sliding wedge 24 and a brake block 2201 that slidably engages with the fixing plate 21 are mounted on the lifting frame 25; a mounting plate 26 is mounted on the lifting plate 25; multiple sets of fixing wedges 2601 that engage with the sliding wedge 24 are mounted on the mounting plate 26; the two ends of the return spring 23 abut against the fixing plate 21 and the lifting frame 22, respectively.

[0047] As a further embodiment of the present invention, the sliding wedge 24 is inclined on both its upper and lower surfaces; during the process of the mounting plate 26 rising or falling, multiple sets of fixed wedges 2601 can alternately press and cooperate with the sliding wedge 24.

[0048] In this embodiment, initially, the lifting plate 25 is in a low position, and the mounting plate 26 and fixing wedge 2601 on it are also in a low position. At this time, the elastic force of the return spring 23 keeps the lifting frame 22 in a relatively high position, the brake block 2201 disengages from the rotating shaft 20, and the rotating shaft 20 can rotate freely.

[0049] When the sensing module 4 detects an environmental anomaly and controls the motor 28 to lift the lifting plate 25, the mounting plate 26 rises synchronously. Multiple sets of fixed wedges 2601, arranged vertically at equal intervals on the mounting plate 26, rise accordingly. Since both the upper and lower surfaces of the sliding wedge 24 are designed as inclined surfaces, when a set of fixed wedges 2601 rises to contact the lower inclined surface of the sliding wedge 24, it will compress the sliding wedge 24, causing it to slide horizontally. As the sliding wedge 24 slides, it will compress against the inclined surface of the triangular block 2202 on the lifting frame 22, thereby converting the horizontal thrust into downward pressure, overcoming the elastic force of the return spring 23, and pushing the entire lifting frame 22 downward along the fixed plate 21. The downward movement of the lifting frame 22 causes the brake block 2201 on it to move downward synchronously, applying radial compressive force to the outer circumferential surface of the rotating shaft 20, generating a friction braking effect, and beginning to decelerate the rotating shaft 20 and its connected harvesting module 2.

[0050] As the mounting plate 26 continues to rise, the fixed wedge 2601 passes the sliding wedge 24, and the squeezing force on the sliding wedge 24 disappears. At this time, under the restoring force of the return spring 23, the lifting frame 22 drives the brake block 2201 to move upward, disengaging from the rotating shaft 20, and the brake is temporarily released. The rotating shaft 20 can then rotate freely for a short time due to inertia (or decelerate slowly). Simultaneously, the upward movement of the lifting frame 22 pushes the sliding wedge 24 to reset (sliding away from the lifting frame 22) through the triangular block 2202, preparing for the next braking.

[0051] Subsequently, the adjacent set of fixed wedges 2601 on the mounting plate 26 rises to contact the sliding wedge 24, repeating the above-mentioned cycle of "squeezing-sliding-pressing brake-releasing reset". In this way, multiple sets of fixed wedges 2601 alternately and periodically act on the sliding wedge 24 during the rising process, driving the brake block 2201 to perform intermittent radial braking action on the rotating shaft 20 in the form of "squeezing brake-brief release-squeezing brake again".

[0052] Intermittent braking gradually dissipates the enormous rotational inertial energy of the harvesting module 2 through repeated friction, achieving a smooth deceleration to a stop. This effectively avoids mechanical shock, component damage, or transmission system overload caused by instantaneous rigid braking. It also provides a brief stress release window for the system, preventing overheating of the braking components and improving the controllability and safety of the braking process. When the environment returns to normal and the lifting plate 25 descends, the mounting plate 26 and the fixing wedge 2601 descend synchronously, the braking components stop working, and the return spring 23 completely lifts the lifting frame 22 and the brake block 2201, disengaging them from the rotating shaft 20. This creates space for the harvesting module 2 to regain power and resume normal operation. During the process of the driving disc 14 moving towards the driven disc 15 and attempting to engage, if the brake block 2201 happens to press down, applying a large braking force to the rotating shaft 20, the driven disc 15 will momentarily become difficult to rotate. At this time, the interaction between the inclined surfaces of the driving tooth block 1401 and the driven tooth block 1501 generates an axial force that pushes the driving disc 14 away from the driven disc 15. This component force will overcome the preload of the buffer spring 17, forcing the drive disc 14 to move backward a short distance along the drive shaft 7, thereby preventing damage to the device structure.

[0053] As a further embodiment of the present invention, the transmission component includes a linkage shaft 30 and an adjustment shaft 9 rotatably mounted on the mounting bracket 3. The linkage shaft 30 is provided with a groove group, and the lifting plate 25 is provided with an adjustment protrusion 2501 that slides and engages with the groove group. The adjustment shaft 9 and the linkage shaft 30 are connected by a bevel gear group.

[0054] As a further embodiment of the present invention, the groove group includes an ascending straight groove 3001, a deceleration inclined groove 3002, a descending straight groove 3003, and an acceleration inclined groove 3004 connected sequentially at their ends; wherein when the adjusting protrusion 2501 cooperates with the deceleration inclined groove 3002 or the acceleration inclined groove 3004, it can drive the adjusting shaft 9 to rotate, thereby reducing or increasing the speed of the drive shaft 7.

[0055] In this embodiment, during the upward movement of the lifting plate 25, the adjusting protrusion 2501 first slides in the rising straight groove 3001, during which the linkage shaft 30 does not rotate. Then, it slides in the deceleration inclined groove 3002, at which point the linkage shaft 30 rotates and drives the adjusting shaft 9 to rotate via the bevel gear set, thereby reducing the transmission ratio between the power shaft 5 and the drive shaft 7. This results in a relatively lower rotational speed of the drive shaft 7, facilitating smooth execution of subsequent actions and reducing system impact. When the lifting plate 25 drives the adjusting protrusion 2501 to slide into the descending straight groove 3003, the linkage shaft 30 stops rotating again, the transmission ratio remains unchanged, and the system maintains a low-speed state. During this process, the active gear block 1401 meshes with the driven gear block 1501. Finally, when the adjusting protrusion 2501 slides into the speed-increasing groove 3004, it will drive the linkage shaft 30 to rotate in the opposite direction, thereby driving the adjusting shaft 9 through the bevel gear set, increasing the transmission ratio between the power shaft 5 and the active shaft 7, so that the speed of the active shaft 7 can be restored to the high speed required for normal harvesting. That is, after the active disk 14 and the driven disk 15 are separated by the speed change component, the speed of the active disk 14 is reduced, so that during the subsequent re-engagement process, the impact force of the active gear block 1401 on the driven gear block 1501 is reduced, thereby avoiding structural damage and improving service life.

[0056] As a further embodiment of the present invention, the transmission component further includes multiple sets of driving half-pulleys 6 slidably fitted onto the power shaft 5 and symmetrically arranged; multiple sets of driven half-pulleys 8 slidably fitted onto the drive shaft 7; the multiple sets of driving half-pulleys 6 and the multiple sets of driven half-pulleys 8 are connected by a steel belt 12; multiple sets of driving sleeves 11 rotatably connected to the driving half-pulleys 6 and driven sleeves 10 rotatably connected to the driven half-pulleys 8 are sleeved on the adjusting shaft 9; multiple sets of symmetrically arranged driven inclined grooves 901 and multiple sets of symmetrically arranged driving inclined grooves 902 are provided on the adjusting shaft 9; driving protrusions 1101 slidably fitted onto the driving inclined grooves 902 are installed on the driving sleeves 11; driven protrusions 1001 slidably fitted onto the driven inclined grooves 901 are installed on the driven sleeves 10.

[0057] As a further embodiment of the present invention, when the combined component drives the active disk 14 to approach the driven disk 15, after the active tooth block 1401 meshes with the driven tooth block 1501, the adjusting protrusion 2501 slides in the descending straight groove 3003 toward the speed-increasing inclined groove 3004.

[0058] In this embodiment, when the adjusting protrusion 2501 slides in the deceleration sloping groove 3002, the adjusting shaft 9 rotates in the forward direction, thereby driving the active sloping groove 902 and the driven sloping groove 901 to rotate. During this process, the active sleeve 11 is driven away from each other by the active protrusion 1101, while the driven sleeve 10 is driven closer to each other by the driven protrusion 1001. The steel belt 12 slides on the active half pulley 6 and approaches the power shaft 5, and slides on the driven half pulley 8 and moves away from the active shaft 7. The transmission ratio between the power shaft 5 and the active shaft 7 is reduced, and the rotational speed of the active disc 14 is reduced.

[0059] When the adjusting protrusion 2501 slides in the speed-increasing sloping groove 3004, the adjusting shaft 9 rotates in the opposite direction, thereby driving the active sloping groove 902 and the driven sloping groove 901 to rotate. During this process, the active protrusion 1101 drives the active sleeve 11 to move closer to each other, while the driven protrusion 1001 drives the driven sleeve 10 to move further away from each other. The steel belt 12 slides away from the power shaft 5 on the active half pulley 6 and slides closer to the active shaft 7 on the driven half pulley 8. The transmission ratio between the power shaft 5 and the active shaft 7 increases, and the rotational speed of the active disc 14 increases.

[0060] That is, after the drive disc 14 and driven disc 15 are separated by the transmission component, the speed of the drive disc 14 is reduced, so that during the subsequent re-engagement process, the impact force of the drive tooth block 1401 on the driven tooth block 1501 is reduced, thereby avoiding structural damage and improving service life. Moreover, when the drive tooth block 1401 and driven tooth block 1501 are engaged, the adjusting protrusion 2501 slides in the descending straight groove 3003 towards the speed-increasing inclined groove 3004, which can avoid damage such as tooth breakage and impact that may occur during high-speed engagement, thus improving the reliability and service life of the system.
