Description

Technical Field

[0001] This invention relates to the field of seeder guidance technology, specifically to an automatic ridge line recognition and correction guidance mechanism for a seeder. Background Technology

[0002] In modern agriculture, ridge planting is a widely used technique, especially suitable for various crops such as corn, soybeans, and cotton. This technique, by creating raised "ridges" and "furrows" (i.e., ridge lines) in the field, can effectively increase soil temperature, improve soil aeration, promote drainage and flood prevention, and facilitate subsequent field management.

[0003] However, in actual sowing operations, accurately sowing along the pre-set ridge lines is a crucial step in ensuring crop yield and quality, and also a technical challenge. Traditional seeders typically rely on the tractor driver's visual observation and experience to manually adjust the direction, which presents the following significant problems:

[0004] Manual operation makes it difficult to maintain the seeder's direction of travel perfectly parallel to the ridge line, which can easily lead to ridge deviation, seedling crushing, and uneven row spacing, affecting ventilation, lighting, and subsequent mechanical operations. It also involves high labor intensity: the driver needs to concentrate on observing the ridge line for a long time, which can easily cause fatigue, further reducing the accuracy and efficiency of the operation. It also requires high driver skills: only experienced drivers can ensure a certain level of operation quality, which increases labor costs and training difficulty. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic ridge line recognition and correction guidance mechanism for a seeder, so as to solve the problems mentioned in the background art.

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

[0007] An automatic ridge line recognition and correction guiding mechanism for a seeder includes a first connecting plate and two second connecting plates mounted on the seeder. The first connecting plate has at least four first mounting holes, and the second connecting plates have at least four second mounting holes. The first connecting plate and the second connecting plates are fixedly mounted on the seeder via the first mounting holes, the second mounting holes, and bolts. The mechanism is characterized by further comprising:

[0008] An adjustment and correction mechanism is provided, which is connected to the seeder via a first connecting plate and a second connecting plate. The adjustment and correction mechanism includes two correction units, a dual-axis motor, and two adjusting rods. The two correction units are respectively installed at one end of the two adjusting rods. The adjustment and correction mechanism adjusts the distance between the two adjusting rods via the dual-axis motor, thereby adjusting the distance between the two correction units so that the guide wheel in the correction unit is located within the ridge line.

[0009] The identification system is installed on the correction unit and includes a control host, a control panel, a first servo motor, a second servo motor, a camera, a lidar, a gyroscope, an image recognition module, an AI learning module, and a spacing adaptive module. The control host and the control panel are both fixedly installed on the top of the adjusting rod. The identification system uses the image recognition module and the camera to capture images of the environment around the seeder, generates an image of the surrounding environment, and identifies the ridge lines. At the same time, the identification system automatically controls the correction unit based on the identified images. The spacing adaptive module uses the lidar to scan the ridge width and ridge height data and automatically matches the ridge parameters for different crops. An ultrasonic sensor is installed on one side of the adjusting rod and is used to identify and detect the protrusions and depressions in the field ahead.

[0010] A shock-absorbing component is installed on the correction unit. The shock-absorbing component reduces vibration by absorbing vibration through the guide wheel. The shock-absorbing component adjusts the shock-absorbing effect by identifying the bulges and depressions of the field through the ultrasonic sensor.

[0014] Optionally, a connecting plate is fixedly installed at the bottom of the movable rod, and an extension rod is fixedly installed at the bottom of the connecting plate. There are two extension rods. A guide wheel is rotatably connected to one end of the extension rod and is located between the two extension rods. The gyroscope is fixedly installed on one side of the extension rod.

[0015] Optionally, the shock absorption assembly includes a mounting rod, a spring, and a second electric push rod. The mounting rod is fixedly installed at the bottom of the limiting member. The bottom of the limiting groove has a liquid storage cavity that fits with the mounting rod. The bottom of the mounting rod has a flow hole, and the interior of the mounting rod communicates with the liquid storage cavity through the flow hole. The flow hole is a conical hole with a chamfered bevel at the top. The spring is installed on the side wall of the movable rod and is located between the top of the connecting plate and the bottom of the mounting cylinder. The second electric push rod is fixedly installed inside the mounting rod, and a push plate is fixedly installed at the output end of the second electric push rod. The push plate is located inside the mounting rod.

[0016] Optionally, a mounting base is fixedly installed on one side of the first connecting plate, and the dual-axis motor is fixedly installed on one side of the mounting base.

[0017] Optionally, a threaded rod is fixedly installed at the output end of the dual-axis motor. A sliding groove is provided inside the adjusting rod, and a threaded hole is provided at one end of the sliding groove. The threaded hole fits with the threaded rod, and the adjusting rod is threadedly connected to the threaded rod through the threaded hole. A groove is provided at the other end of the sliding groove, and a guide rod is fixedly installed inside the groove.

The humidity sensor is fixedly installed inside the anti-slip component. The anti-slip component is an arc-shaped component. A cleaning brush is fixedly installed at the bottom of the connecting plate. A drain hole is opened inside the extension rod, and the drain hole corresponds to the cleaning brush.

[0020] This invention has at least the following beneficial effects:

[0021] (1) This solution sets up an adjustment and correction mechanism and an identification system. Before the operation begins, the spacing adaptive module scans the ridge width and ridge height data with laser radar, automatically matches the ridge type parameters of different crops, automatically matches the preset ridge type parameters of crops such as corn / soybeans, calculates the optimal spacing between the two guide wheels and feeds it back to the control host, and automatically adjusts the spacing so that the two guide wheels can fall into the ridge line on both sides. During the movement of the seeder, if the machine body is tilted, the identification system judges the deviation and controls the rotation of the guide wheels to automatically correct the deviation. The driver only needs to pay attention to the macro operation status and does not need to concentrate on visual alignment for a long time. The gear transmission mechanism driven by the servo motor realizes the high-precision and fast-response angle adjustment of the guide wheels, ensuring that the seeder always moves accurately along the ridge line, effectively avoiding problems such as ridge deviation and seedling crushing, laying a solid foundation for high and stable crop yield, thereby greatly improving work efficiency.

[0022] (2) This solution sets up a shock-absorbing component. When a depression is detected in front, the control host sends an extension command to the second electric push rod. The second electric push rod drives the push plate to move downward, reducing the flow cross section of the flow hole, increasing the flow resistance of the damping fluid, and improving the support force of the shock-absorbing component. This prevents the identification deviation caused by excessive sinking of the guide wheel. At the same time, when the guide wheel encounters a protrusion or depression, the movable rod will compress or stretch the spring for preliminary mechanical buffering. The up and down sliding of the movable rod will change the volume of the damping fluid in the reservoir. When the damping fluid passes through the flow hole, especially its conical structure and chamfered slope, it will generate damping force, effectively absorbing and attenuating high-frequency vibrations, minimizing the impact of vibrations on precision identification systems such as cameras, lidar, and gyroscopes, and ensuring the accuracy of identification data.

[0023] (3) This solution collects soil moisture data in real time through the humidity sensor inside the anti-slip component and transmits the data to the control host. The control host determines the current anti-slip requirements of the soil based on the soil moisture value: when the soil moisture is high and slippery, the control host sends an extension command to the first electric push rod. The first electric push rod pushes the anti-slip component to extend to the outside of the guide wheel, increasing the contact area and friction between the anti-slip component and the side wall of the furrow, and preventing the guide wheel from slipping; when the soil moisture is low and dry, the control host sends a retraction command to the first electric push rod. The first electric push rod drives the anti-slip component to retract into the installation cavity, reducing the travel resistance of the guide wheel and ensuring work efficiency.

[0024] (4) This solution uses a cleaning brush to continuously clean the mud and weeds on the surface of the guide wheel when it rotates, preventing them from clogging the surface of the guide wheel and ensuring the sensitivity of the guide. The debris that is cleaned off can be discharged through the drain hole. Attached Figure Description

[0042] 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.

[0043] Please see Figures 1-14This invention provides an automatic ridge line recognition and correction guiding mechanism for a seeder, comprising a first connecting plate 1 and two second connecting plates 2 mounted on the seeder. The first connecting plate 1 has at least four first mounting holes 101 inside, and the second connecting plates 2 have at least four second mounting holes 201 inside. The first connecting plate 1 and the second connecting plates 2 are fixedly mounted on the seeder via the first mounting holes 101, the second mounting holes 201, and bolts. The mechanism also includes:

[0044] The adjustment and correction mechanism is connected to the seeder through the first connecting plate 1 and the second connecting plate 2. The adjustment and correction mechanism includes two correction units, a dual-shaft motor 103 and two adjusting rods 3. The two correction units are respectively installed at one end of the two adjusting rods 3.

[0045] The identification system, installed on the correction unit, includes a control host 5, a control panel 501, a first servo motor 502, a second servo motor 504, a camera 506, a lidar 507, a gyroscope 508, an image recognition module 509, and an AI learning module 510. The control host 5 and control panel 501 are both fixedly mounted on the top of the adjusting rod 3. The identification system uses the image recognition module 509 and camera 506 to capture images of the environment surrounding the seeder, generating images of the surrounding environment and identifying the ridge lines. Simultaneously, the identification system automatically controls the correction unit based on the identified images. The spacing adaptive module 511 scans the ridge width using the lidar 507. The system automatically matches ridge height data with ridge type parameters for different crops. An ultrasonic sensor 613 is installed on one side of the adjusting rod 3 to identify and detect protrusions and depressions in the field ahead. The control panel 501 starts the system, and the control host 5 activates the laser radar 507 and the spacing adaptive module 511. The laser radar 507 scans the ridge width and height, generating three-dimensional data which is transmitted to the spacing adaptive module 511. The module automatically matches preset ridge type parameters for crops such as corn and soybeans, calculates the optimal spacing between the two guide wheels 407, and feeds it back to the control host 5, automatically adjusting the spacing. The control host 5 is connected to the control panel 501 and the first servo motor 5 via wires. 02. The second servo motor 504 is connected to the dual-axis motor 103. The control host 5 is connected to the camera 506, lidar 507, and gyroscope 508 via a Bluetooth module. The camera 506 serves as the main visual sensor, primarily responsible for acquiring image information of the ridges and crops. The lidar 507 is used to acquire three-dimensional depth information of the terrain and furrows ahead. It is unaffected by changes in lighting and can assist in confirming the position of the ridges in complex environments. The gyroscope 508 serves as an inertial sensor, providing real-time attitude and angular velocity information of the guide wheel 407, enabling rapid response to fast dynamic offsets. The control host 5 acts as the "brain" of the entire mechanism, integrating all sensor data. The system performs calculations and makes decisions, and sends precise control commands to the dual-axis motor 103, the first servo motor 502, and the second servo motor 504. The image recognition module 509 receives images from the camera 506 and the lidar 507, and identifies the ridge lines through built-in image processing algorithms such as edge detection and color space segmentation. The AI ​​learning module 510 can use the data from the lidar 507 and the gyroscope 508 as "true values" or references during operation to verify and correct the recognition results of the image recognition module 509. During operation, the camera 506 captures the ridge line environment, the lidar 507 scans the three-dimensional terrain, and the data is transmitted to the control host 5.The image recognition module 509 processes the image to extract ridge line features, combines it with data from the lidar 507 to eliminate interference, determines the ridge line baseline path, compares it with the preset path, and uses attitude data from the gyroscope 508 to calculate the offset distance and angle, determining whether it exceeds the threshold. If the distance between the guide wheel 407 and the ridge line is uneven, the control host 5 drives the dual-axis motor 103, causing the threaded rod 104 to rotate. The adjusting rod 3 moves along the threaded rod 104 to adjust the distance between the two correction units, making the distance between the guide wheel 407 and the ridge line equal. If the machine body deviates from the ridge line, the control host... 5. Start the first servo motor 502, which drives the rotating shaft 6 and the mounting plate 603 to rotate. Through the meshing of the toothed groove 606 and the gear 605, the rotating cylinder 604 rotates. Then, through the limiting member 607 and the limiting groove 401, the guide wheel 407 swings, generating a reverse corrective force to straighten the machine body. Feedback calibration: During the correction process, the camera 506 and the lidar 507 continuously collect data, and the image recognition module 509 dynamically tracks the ridge line and compares the corrected path with the baseline path. If there is still a deviation, the motor parameters are finely adjusted until the machine body moves along the ridge line.

[0046] The shock absorption component is installed on the correction unit. The shock absorption component reduces vibration by actuating the guide wheel 407. The shock absorption component adjusts the shock absorption effect by identifying the bumps and depressions of the field through the ultrasonic sensor 613. The guide wheel 407 is equipped with a humidity sensor 412 that can adaptively adjust the anti-slip effect according to the soil moisture.

[0047] In some embodiments, see Figure 3 , Figure 6The correction unit includes a rotating shaft 6, a mounting cylinder 601, a protective cylinder 602, a mounting plate 603, a rotating cylinder 604, a movable rod 4, and a gear 605. The rotating shaft 6 is rotatably connected to one end of the adjusting rod 3. The mounting plate 603 is fixedly mounted on one end of the rotating shaft 6. The mounting cylinder 601 is fixedly mounted on one end of the adjusting rod 3. The protective cylinder 602 is fixedly mounted on the side wall of the mounting cylinder 601. The rotating cylinder 604 is rotatably connected to the inside of the mounting cylinder 601. The gear 605 is fixedly mounted on the side wall of the rotating cylinder 604 and is located inside the protective cylinder 602. The side wall of the mounting plate 603 has several tooth grooves 606 that mesh with the gear 605. The mounting plate 603 meshes with the gear 605 via the toothed groove 606. A limiting member 607 is fixedly installed on the inner wall of the rotating cylinder 604. A limiting groove 401, which matches the limiting member 607, is opened on the side wall of the movable rod 4. The limiting member 607 is slidably connected inside the limiting groove 401. The movable rod 4 is slidably connected inside the rotating cylinder 604 via the limiting groove 401 and the limiting member 607. The movable rod 4 is drively connected to the rotating cylinder 604 via the limiting groove 401 and the limiting member 607. The guide wheel 407 is installed at the bottom of the movable rod 4. It should be noted that the rotation of the mounting plate 603 can be controlled by the rotation of the rotating shaft 6. When 603 rotates, it meshes with gear 605 through tooth groove 606, thereby driving gear 605 to rotate. The rotation of gear 605 drives rotating cylinder 604 and movable rod 4 inside rotating cylinder 604 to rotate together. By setting limiting groove 401 and limiting member 607, the movable rod 4 can slide up and down inside rotating cylinder 604 without affecting the rotation of rotating cylinder 604 driving movable rod 4. Adjusting the correction mechanism adjusts the distance between two adjusting rods 3 through dual-axis motor 103, thereby adjusting the distance between two correction units, so that the guide wheel 407 in the correction unit is located within the ridge line. Operation control panel 50 1. A start command is sent to the control host 5. The control host 5 drives the dual-axis motor 103 to start. The two ends of the dual-axis motor 103 output rotational motion in opposite directions, which drives the threaded rods 104 on both sides to rotate synchronously. Since the adjusting rod 3 is threadedly connected to the threaded rod 104 through the threaded hole 301 opened inside, the rotation of the threaded rod 104 will be converted into the linear motion of the adjusting rod 3 along the axial direction. At the same time, the guide rod 303 installed in the groove 304 in the sliding groove 302 inside the adjusting rod 3 is inserted into the through hole 105 at one end of the threaded rod 104, which plays a guiding and constraining role on the movement of the adjusting rod 3, and prevents the adjusting rod 3 from tilting during the movement.Furthermore, the guide hole 204 inside the sliding plate 202 fixed on one side of the second connecting plate 2 is fitted onto the outside of the threaded rod 104, further assisting in ensuring the stability of the movement of the adjusting rod 3. Under the dual constraint of the guide rod 303 and the guide hole 204, the adjusting rods 3 on both sides will move inward or outward simultaneously, thereby driving the correction units installed at one end of the two adjusting rods 3 to move synchronously, precisely adjusting the distance between the two correction units until the guide wheel 407 installed at the bottom of the movable rod 4 inside the correction unit can fall exactly into the furrow line on both sides, completing the initial distance calibration.

[0048] In some embodiments, see Figure 6 The first servo motor 502 is fixedly installed at one end of the top of the adjusting rod 3, and the rotating shaft 6 is fixedly installed at the output end of the first servo motor 502. It should be noted that the first servo motor 502 can be used to control the rotation of the rotating shaft 6.

[0049] In some embodiments, see Figure 3 , Figure 4 A mounting bracket 503 is fixedly installed on the side wall of the protective cylinder 602. A second servo motor 504 is fixedly installed on the side wall of the mounting bracket 503. An adjustment shaft 505 is installed inside the mounting bracket 503. The adjustment shaft 505 is fixedly installed at the output end of the second servo motor 504. The adjustment shaft 505 is rotatably connected to the inside of the mounting bracket 503 through the second servo motor 504. A camera 506 is fixedly installed on the side wall of the adjustment shaft 505. The camera 506 is located on top of the guide wheel 407. It should be noted that by setting the second servo motor 504, it can be used to control the rotation of the adjustment shaft 505. The rotation of the adjustment shaft 505 can drive the camera 506 to rotate, thereby adjusting the pitch angle of the camera 506 to obtain the best shooting field of view.

[0050] In some embodiments, see Figure 9 , Figure 10 A connecting plate 404 is fixedly installed at the bottom of the movable rod 4, and an extension rod 405 is fixedly installed at the bottom of the connecting plate 404. There are two extension rods 405. A guide wheel 407 is rotatably connected to one end of the extension rod 405. The guide wheel 407 is located between the two extension rods 405. A gyroscope 508 is fixedly installed on one side of the extension rod 405. It should be noted that by placing the gyroscope 508 on one side of the extension rod 405, it is possible to better provide real-time attitude and angular velocity information of the guide wheel 407.

[0051] In some embodiments, see Figure 7 , Figure 8 , Figure 9The shock absorption assembly includes a mounting rod 608, a spring 402, and a second electric push rod 611. The mounting rod 608 is fixedly installed at the bottom of the limiting member 607. The bottom of the limiting groove 401 has a liquid storage cavity 403 that fits with the mounting rod 608. The bottom of the mounting rod 608 has a flow hole 609, and the interior of the mounting rod 608 is connected to the liquid storage cavity 403 through the flow hole 609. The flow hole 609 is a tapered hole, and the top of the flow hole 609 has a chamfered bevel 610. The spring 402 is installed on the side wall of the movable rod 4 and is located on the connecting plate. Between the top of 404 and the bottom of the mounting cylinder 601, the second electric push rod 611 is fixedly installed inside the mounting rod 608. A push plate 612 is fixedly installed at the output end of the second electric push rod 611, located inside the mounting rod 608. It should be noted that the liquid storage chamber 403 is filled with damping fluid. During the seeding operation, severe vibrations are usually present, which can seriously affect the stability and lifespan of precision electronic equipment and optical components. By setting up a shock-absorbing component, when the guide wheel 407 encounters a protrusion or depression, the movable rod 4 will compress or stretch the spring 4. 02. Initial mechanical buffering is performed. Simultaneously, the up-and-down sliding of the movable rod 4 changes the volume of the damping fluid in the storage chamber 403. The damping fluid generates damping force when passing through the flow hole 609, especially its conical structure and chamfered slope 610. The ultrasonic sensor 613 on one side of the adjusting rod 3 continuously detects the protrusions and depressions of the field ahead during the seeder's movement, feeding back the terrain data to the control host 5 in real time. When a protruding terrain is detected ahead, the control host 5 sends a retraction command to the second electric push rod 611. The second electric push rod 61... 1. The push plate 612 moves upward, increasing the flow cross-section of the flow hole 609, reducing the flow resistance of the damping fluid, making the damping effect of the shock absorption assembly more gentle, and preventing the guide wheel 407 from being subjected to severe impact. When a depression is detected in front, the control host 5 sends an extension command to the second electric push rod 611. The second electric push rod 611 drives the push plate 612 downward, reducing the flow cross-section of the flow hole 609, increasing the flow resistance of the damping fluid, improving the support force of the shock absorption assembly, and preventing the guide wheel 407 from sinking excessively, which could cause recognition deviation.

[0052] Meanwhile, when the guide wheel 407 encounters a protrusion or depression, the movable rod 4 will compress or stretch the spring 402 for initial mechanical buffering; the up-and-down sliding of the movable rod 4 will change the volume of the damping fluid in the reservoir 403. When the damping fluid passes through the flow hole 609, especially its conical structure and chamfered slope 610, it will generate damping force, effectively absorbing and attenuating high-frequency vibrations, minimizing the impact of vibrations on precision identification systems such as the camera 506, lidar 507, and gyroscope 508, and ensuring the accuracy of the identification data.

[0054] In some embodiments, see Figure 2 , Figure 3 , Figure 4 A threaded rod 104 is fixedly installed at the output end of the dual-axis motor 103. A sliding groove 302 is provided inside the adjusting rod 3. A threaded hole 301 is provided at one end of the sliding groove 302, which fits with the threaded rod 104. The adjusting rod 3 is threadedly connected to the threaded rod 104 through the threaded hole 301. A groove 304 is provided at the other end of the sliding groove 302. A guide rod 303 is fixedly installed inside the groove 304. A through hole 105 is provided at one end of the threaded rod 104, which fits with the guide rod 303. The guide rod 303 is located inside the through hole 105. It should be noted that by installing the threaded rod 104 at the output end of the dual-axis motor 103, the dual-axis motor 103 can control the rotation of the threaded rod 104. By setting the threaded hole 301, the rotation of the threaded rod 104 can cause the adjusting rod 3 to move to one side. By setting the guide rod 303, the stability of the connection between the adjusting rod 3 and the threaded rod 104 can be increased, and tilting can be avoided.

[0055] In some embodiments, see Figure 3 , Figure 4 A sliding plate 202 is fixedly installed on one side of the second connecting plate 2, and a fixed plate 203 is fixedly installed on one end of the sliding plate 202. The fixed plate 203 is located on one side of the adjusting rod 3. The laser radar 507 is fixedly installed on one side of the fixed plate 203.

It should be noted that by opening the guide hole 204 in the sliding plate 202, the movement of the adjusting rod 3 can be avoided.

[0056] In some embodiments, see Figure 9 , Figure 10The guide wheel 407 has several mounting cavities 410 inside, and a first electric push rod 411 is fixedly installed inside each mounting cavity 410. An anti-slip component 408 is fixedly installed at the output end of the first electric push rod 411. The anti-slip component 408 is located on the outside of the guide wheel 407. A humidity sensor 412 is fixedly installed inside the anti-slip component 408. The anti-slip component 408 is an arc-shaped component. A cleaning brush 409 is fixedly installed at the bottom of the connecting plate 404. A drain hole 406 is opened inside the extension rod 405, and the drain hole 406 corresponds to the cleaning brush 409. It should be noted that the anti-slip component 408 on the side wall of the guide wheel 407 can increase the friction with the side wall of the furrow, prevent slippage under wet soil conditions, and improve the reliability of the guide. By setting the cleaning brush 409, the guide wheel 407 can be continuously cleaned of mud and weeds on its surface when it rotates, preventing it from becoming clogged. On the surface of the guide wheel 407, the guiding sensitivity is ensured. The debris that is cleaned can be discharged through the drain hole 406. The humidity sensor 412 inside the anti-slip component 408 collects soil moisture data in real time and transmits the data to the control host 5. The control host 5 determines the current anti-slip requirements of the soil based on the soil moisture value: when the soil moisture is high and slippery, the control host 5 sends an extension command to the first electric push rod 411. The first electric push rod 411 pushes the anti-slip component 408 to extend outward from the guide wheel 407, increasing the contact area and friction between the anti-slip component 408 and the side wall of the furrow, thus preventing the guide wheel 407 from slipping; when the soil moisture is low and dry, the control host 5 sends a retraction command to the first electric push rod 411. The first electric push rod 411 drives the anti-slip component 408 back into the mounting cavity 410, reducing the travel resistance of the guide wheel 407 and ensuring work efficiency.

[0057] The workflow and principle of this invention are as follows: After the system starts, the lidar 507 scans the three-dimensional data of the ridge width and ridge height of the field and transmits it to the spacing adaptive module 511. The module automatically matches the preset ridge type parameters of crops such as corn and soybeans to determine the optimal spacing of the guide wheels 407. The ultrasonic sensor 613 detects the raised and sunken terrain of the field in front in real time, and the humidity sensor 412 collects soil moisture data. During the operation, the camera 506 continuously captures images of the ridge line environment. Combined with the three-dimensional terrain data of the lidar 507, the image recognition module 509 extracts the ridge line features through edge detection and color segmentation algorithms, and removes weeds and soil. Block interference is detected to determine the baseline path for the ridge line. The gyroscope 508 collects real-time attitude and angular velocity data of the guide wheel 407, providing dynamic basis for deviation judgment. The control host 5 integrates all sensor data. The AI ​​learning module 510 uses data from the lidar 507 and gyroscope 508 as references to verify and correct the recognition results of the image recognition module 509, improving the accuracy of ridge line recognition. The control host 5 compares the recognized baseline path of the ridge line with the preset path, calculates the offset distance and angle using data from the gyroscope 508, and determines whether it exceeds the set threshold. If the distance between the guide wheel 407 and the ridge line is uneven, the control host 5 drives the dual-axis motor 1. 03. The threaded rod 104 is rotated, and the adjusting rod 3 moves linearly under the constraint of the guide rod 303 and the guide hole 204, finely adjusting the distance between the two correction units to restore the guide wheel 407 and the ridge line distance to be equal. If the machine body deviates from the ridge line, the control host 5 starts the first servo motor 502, which drives the rotating shaft 6 and the mounting plate 603 to rotate. Through the meshing of the gear 605 with the toothed groove 606, the rotating cylinder 604 is driven to rotate. Then, through the transmission of the limiting part 607 and the limiting groove 401, the movable rod 4 and the guide wheel 407 swing, generating a reverse correction force to push the machine body back to the correct position. During the correction process, the camera 506 and the laser radar 507 continuously reflect the correction. Feedback data allows the control host 5 to dynamically fine-tune motor parameters until the machine body moves stably along the ridge line, forming a closed-loop correction. Soil moisture adaptive anti-slip: The control host 5 adjusts the anti-slip strategy based on the data from the humidity sensor 412. Under wet conditions, the first electric push rod 411 extends, pushing the anti-slip part 408 to extend and increase friction. Under dry conditions, the anti-slip part 408 retracts to reduce travel resistance. Based on the terrain data from the ultrasonic sensor 613, the control host 5 adjusts the extension and retraction of the second electric push rod 611, driving the push plate 612 to change the flow cross section of the flow hole 609. When encountering a protrusion, the flow cross section is increased to reduce damping force, achieving gentle buffering.When encountering a depression, the flow cross-section is reduced to increase damping force and enhance support. Simultaneously, the mechanical buffer of spring 402 and the damping fluid in the reservoir 403 generate damping force through the tapered flow hole 609, absorbing high-frequency vibrations and protecting the precision sensor. When the guide wheel 407 rotates, the cleaning brush 409 at the bottom of the connecting plate 404 continuously cleans the wheel surface of mud and weeds. Debris is discharged through the drain hole 406 of the extension rod 405, preventing blockage and ensuring guiding sensitivity. The camera 506's field of view is adjusted: commands are sent via the control panel 501 to control the host 5 to drive the second servo motor 504, which in turn rotates the adjustment shaft 505 and the camera 506, adjusting the pitch angle to obtain the optimal shooting field of view and ensuring the stability of ridge line recognition.
