Description

Technical Field

[0001] This invention relates to the field of agricultural machinery, specifically to an integrated intelligent replanting device for sugarcane that prevents clogging. Background Technology

[0002] Sugarcane, as an important sugar crop and cash crop in my country, is widely planted, and replanting is a crucial step in ensuring sugarcane yield. During sugarcane cultivation, factors such as climate disasters, pest and disease attacks, and poor sowing quality often lead to gaps in the rows and missing seedlings. If replanting is not done in a timely manner, it will result in a waste of land resources and a significant reduction in yield per unit area. Therefore, replanting operations need to be carried out quickly and efficiently to ensure that the replanted seedlings grow at the same pace as the original seedlings. At the same time, it is necessary to ensure uniform spacing between replanted seedlings and stable seedbed implantation to provide favorable conditions for subsequent growth.

[0003] Currently, sugarcane replanting operations mainly rely on manual labor or simple machinery. Manual replanting involves multiple steps, including digging holes, fertilizing, sowing, and backfilling. This is not only labor-intensive and inefficient, but also suffers from problems such as inconsistent planting spacing, uneven fertilization, and improper seed depth, resulting in low seedling survival rates and difficulty in ensuring the effectiveness of replanting. Simple replanting machinery is mostly single-function equipment, capable of only performing one step, either soil extraction or sowing. It requires multiple machines or manual assistance to complete the entire operation, making the process cumbersome. Furthermore, it lacks anti-clogging design, and when the soil is compacted or the fertilizer becomes damp and clumps together, malfunctions such as blocked soil extraction cylinders and poor fertilizer dispensing can easily occur, affecting the continuity of operations.

[0004] Furthermore, existing replanting machinery often uses fixed spacing, which cannot be flexibly adjusted according to sugarcane variety and planting density requirements, resulting in poor versatility. Simultaneously, most equipment fails to integrate fertilizer and soil mixing, with fertilization and sowing occurring separately, leading to uneven fertilizer distribution, insufficient nutrient supply to replanted seedlings, and further reducing survival rates. With the increasing mechanization and intelligence of agriculture, traditional replanting methods can no longer meet the high-efficiency and precision demands of large-scale sugarcane cultivation. There is an urgent need for an integrated and intelligent replanting device to solve problems such as high labor intensity, low operating efficiency, poor anti-clogging effect, inconvenient spacing adjustment, and uneven fertilizer and soil mixing in existing technologies, providing stable and reliable technical support for sugarcane replanting operations. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an integrated intelligent sugarcane replanting device that prevents clogging, solving the problems of high labor intensity, low efficiency, poor clogging prevention, difficulty in adjusting replanting spacing, uneven fertilizer-soil mixing, and low survival rate associated with traditional methods.

[0007] Preferably, hydraulic cylinders are fixedly installed on both sides of the top of the gantry frame, and the driving ends of the hydraulic cylinders are respectively fixedly installed on both sides of the top of the movable frame.

[0008] Preferably, a plurality of short shafts are evenly and movably installed on the inner top of the movable frame. The bottom end of each short shaft is movably installed with an outer cylinder via a universal joint. The top end of each rotating shaft is movably installed with an inner rod via a universal joint, and the end of each inner rod is movably installed inside the corresponding side of the outer cylinder. Keyways are provided on both sides of the inner wall of the outer cylinder. Splines are fixedly installed at both ends of each inner rod, and the outer ends of the splines are movably disposed inside the corresponding side of the keyway. Transmission gears are fixedly installed on the outer diameter of each short shaft, and the inner ends of the transmission gears are meshed together. A first motor is fixedly installed in the middle of the top of the movable frame, and the drive end of the first motor is fixedly installed on the top end of the middle short shaft.

[0009] Preferably, an adjusting shaft is movably installed on the other side of the inner bottom of the movable frame. Several arc-shaped grooves are evenly opened on the outer diameter of the adjusting shaft, and the pitch of the arc-shaped grooves gradually increases from the center to both sides. Round-headed pins are fixedly installed on the rear end of the soil sampling chamber, and the ends of the round-headed pins are movably disposed inside the corresponding arc-shaped grooves. A second motor is fixedly installed on one side of the bottom of the movable frame, and the drive end of the second motor is fixedly installed on one end of the adjusting shaft.

[0010] Preferably, a switch valve is fixedly installed on the outer diameter of the fertilizer inlet pipe, a cam is fixedly installed on the outer diameter of the middle outer cylinder, and a pad is fixedly installed on one side of the middle part of the fertilizer box.

[0011] Preferably, a fixing rod is fixedly installed at both ends of the seed box, and a slider is fixedly installed at the bottom end of each fixing rod. Slide grooves are opened on both sides of the frame, and the bottom of each slider is movably disposed inside the corresponding slide groove. Connecting rods are movably installed on both sides of the movable frame, and the ends of each connecting rod are movably disposed on the top side of the corresponding slider.

[0012] Preferably, a third motor is fixedly installed on one side of the middle part of the seed box, and one end of the movable shaft in the middle is fixedly installed on the drive end of the third motor. The other end of the movable shaft extends to the outside of the seed box and is fixedly installed with a synchronous pulley. The outer diameters of the synchronous pulleys are connected by a synchronous belt.

[0013] Preferably, a suspension frame is fixedly installed at the front end of the frame, and anti-slip rollers are movably installed on both sides of the bottom end of the frame.

[0014] This invention provides an integrated intelligent replanting device for sugarcane that prevents clogging. It has the following beneficial effects:

[0015] 1. This invention uses a second motor to drive the adjustment shaft to rotate. The arc-shaped groove on the adjustment shaft, with its gradually increasing pitch from the center to both sides, engages with the round-headed pins of the soil sampling chambers, allowing all soil sampling chambers to move synchronously inwards and outwards at equal intervals, thus achieving flexible adjustment of the replanting spacing. Without disassembling or replacing parts, it can adapt to replanting scenarios with different sugarcane varieties and planting densities, significantly improving the device's versatility and adaptability, and reducing equipment adjustment costs for multi-scenario operations.

[0016] 2. This invention uses a soil-crushing drill bit to break up the soil, preventing soil clumping that could clog the soil collection cylinder. The spiral guide vanes rotate synchronously to transport the broken soil upwards, forming a smooth soil flow channel. This completely solves the problem of clogging caused by soil compaction and clumping when collecting soil in traditional replanting devices. Through the cooperation of the cam, pad, and spring rod, the fertilizer box vibrates rapidly. Combined with the control of the switch valve, this ensures that the fertilizer is fed evenly, preventing the fertilizer from getting damp and clumping, which could cause clogging and ensure continuous fertilization.

[0017] 3. This invention simultaneously completes fertilizer delivery and mixing during soil extraction: After the fertilizer box vibrates and discharges the fertilizer, the rotating shaft drives the mixing rod to rotate at high speed, thoroughly mixing the fertilizer with the crushed soil, ensuring the fertilizer is evenly integrated into the soil to form a nutrient matrix. This design avoids the uneven nutrient distribution problem caused by traditional replanting methods of "fertilizing before sowing" or "sowing before fertilizing," providing balanced nutrients to sugarcane seed material and significantly improving the germination rate and seedling growth quality after replanting.

[0018] 4. This invention integrates "spacing adjustment, soil extraction and crushing, fertilizer-soil mixing, precision sowing, and soil backfilling" into one system. By connecting to mobile devices such as tractors, it enables continuous replanting operations while on the move. Compared to the traditional manual replanting process of "digging holes, fertilizing, sowing, and backfilling" in separate steps, it significantly shortens the operation cycle and reduces manpower input. At the same time, the device is equipped with anti-slip rollers and a suspension frame, making it easy to move, stable in connection, and adaptable to different field road conditions, thus reducing the labor intensity of operators.

[0027] The technical solutions in 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.

[0028] Example:

[0029] Please see the appendix Figure 1 - Appendix Figure 7 This invention provides an integrated intelligent replanting device for sugarcane to prevent clogging, such as... Figure 1As shown, the device includes a frame 1, which serves as the core load-bearing foundation for the entire system. Frame 1 securely mounts all key components, including the gantry frame 2 and seed box 28, providing stable support for the coordinated movement of all mechanisms. This ensures the device will not shift or loosen due to vibration during field operations, guaranteeing the accuracy and safety of replanting operations. The gantry frame 2 is fixedly installed at the rear top of frame 1. The gantry frame 2 employs a frame structure design, providing a vertical guide trajectory for the lifting and lowering movement of the movable frame 3. Its stable structure can withstand the weight of components such as the movable frame 3 and the soil extraction chamber 5, preventing swaying when the movable frame 3 descends to extract soil. This lays the foundation for precise control of the soil penetration depth. The movable frame 3 is movably installed inside the gantry frame 2. The movable frame 3 integrates soil extraction and soil breaking. The key carrier of the soil-fertilizer mixing mechanism can be lifted and lowered as a whole under the drive of the hydraulic cylinder 4. Its lifting and lowering action connects different operation stages such as soil taking, sowing, and backfilling, ensuring that each process is carried out in sequence and efficiently. Several soil taking chambers 5 are movably installed on one side of the inner bottom of the movable frame 3. The soil taking chambers 5 provide a closed space for temporary storage of soil after crushing and for mixing fertilizer with soil. This prevents soil or fertilizer from leaking out during the mixing process and ensures the mixing effect of the mixing rod 8 on the soil and fertilizer, ensuring that each group of replanting pits can obtain uniform nutrient soil. Soil taking cylinders 6 are fixedly installed at the bottom of each soil taking chamber 5. The soil taking cylinders 6 are hollow tubular structures that are vertically inserted into the soil when the movable frame 3 descends, forming a cylindrical pit that meets the requirements for sugarcane seed sowing. The diameter of the cylinder is adapted to the sugarcane seed. The size of the soil sampler chamber 5 is designed to provide a channel for the spiral guide vane 9 to transport soil, preventing soil from scattering during transport. Rotating shafts 7 are movably installed inside the sampler chamber 5. These rotating shafts 7 are the core hub for power transmission. The upper end is connected to the outer cylinder 12 via an inner rod 13 to receive rotational power, while the lower end drives the mixing rod 8, spiral guide vane 9, and soil-crushing drill bit 10 to rotate synchronously, achieving integrated soil crushing, transporting, and fertilizer mixing operations. The structure design, which runs through the sampler chamber 5, ensures lossless power transmission. Mixing rods 8 are fixedly installed on both sides of the upper part of the rotating shaft 7. The mixing rods 8 are symmetrically distributed and form a stirring airflow when the rotating shaft 7 rotates at high speed, thoroughly mixing the fertilizer transported by the fertilizer inlet pipe 23 with the crushed soil lifted by the spiral guide vane 9, breaking up fertilizer clumps and ensuring uniform fertilizer mixing. The soil enters the gaps between soil particles, providing a continuous and balanced supply of nutrients for sugarcane seed germination. Spiral guide vanes 9 are fixedly installed on the lower outer side of the rotating shaft 7. These vanes employ a spiral angle design, generating an upward conveying force during rotation to continuously transport the loose soil broken up by the soil-crushing drill bit 10 upwards to the soil-taking chamber 5. Simultaneously, the spiral structure's guiding effect prevents soil accumulation and blockage within the soil-taking cylinder 6, ensuring the continuity of the soil-taking and conveying process. A soil-crushing drill bit 10 is fixedly installed at the bottom of the rotating shaft 7. This drill bit 10 features a conical cutter head design with a sharp tip and a wear-resistant coating, allowing it to quickly cut into the soil during rotation, breaking up compacted soil clods and gravel into fine particles. This reduces the resistance to soil entry into the soil-taking cylinder 6 and prevents large impurities from clogging it.To provide high-quality soil raw materials for subsequent fertilizer-soil mixing and backfilling, a fertilizer box 22 is movably mounted on one side of the movable frame 3 via several spring rods 25. The spring rods 25 have an elastic return function; one end is fixed to the movable frame 3, and the other end connects to the fertilizer box 22, providing elastic support for the fertilizer box 22. Simultaneously, in conjunction with the interaction between the cam 26 and the pad 27, the fertilizer box 22 generates high-frequency vibration. The fertilizer box 22 is a sealed box structure used to store granular or powdered fertilizer required for sugarcane replanting. Its smooth inner wall design prevents fertilizer adhesion and residue, ensuring smooth fertilizer flow. Several spring rods 25 are evenly fixed at the bottom of the fertilizer box 22. Fertilizer inlet pipe 23 extends to the interior of the corresponding soil sampling chamber 5. Each fertilizer inlet pipe 23 corresponds to one soil sampling chamber 5, with its end close to the rotating area of ​​the mixing rod 8. This ensures that the fertilizer is quickly mixed by the mixing rod 8 as soon as it enters the soil sampling chamber 5, preventing fertilizer settling and accumulation. The pipe design also prevents soil from flowing back into the fertilizer box 22. A seed box 28 is located at the top front of the frame 1. The seed box 28 is an open-top box with ample internal space for adding sugarcane seeds. Its sloping bottom design allows the seeds to converge towards the distribution trough 33 under gravity, preventing seed accumulation in the corners of the box and ensuring continuous distribution. The interior of 28 is evenly divided into several distribution troughs 33, which are arranged in parallel. Each distribution trough 33 corresponds to a rotating disk 34 and a feeding pipe 36, forming an independent distribution channel. This ensures that the seed supply in a single distribution trough 33 does not affect other channels, enabling simultaneous replanting operations for multiple groups. A rotating disk 34 is movably mounted inside each distribution trough 33 via a movable shaft 37. The rotating disk 34 fits tightly against the inner wall of the distribution trough 33, rotating without jamming. Its outer diameter is matched to the distribution trough 33, ensuring that the seed can only fall into the receiving trough 35, preventing seed leakage from gaps and inaccurate sowing. Several receiving troughs are provided on the outer diameter of each rotating disk 34. The receiving trough 35 has a volume matched to the volume of a single sugarcane seed, holding only one seed at a time. The seed is transported to the top of the dispensing pipe 36 via the rotation of the rotating disc 34, achieving precise quantitative sowing. The smooth edges of the receiving trough 35 prevent seed jamming. A dispensing pipe 36 is fixedly installed at the bottom of the seed box 28 at a position corresponding to each dispensing trough 33. The dispensing pipe 36 is a vertical tubular structure, with its upper end connected to the dispensing trough 33 and its lower end aligned with the pit excavated by the soil extraction cylinder 6. Its inner wall is smooth, and its diameter is slightly larger than that of the sugarcane seed, ensuring that the seed can fall quickly and smoothly under gravity, preventing seed adhesion and blockage within the pipe.

[0030] In this embodiment, hydraulic cylinders 4 are fixedly installed on both sides of the top of the gantry frame 2, and the drive ends of the hydraulic cylinders 4 are fixedly installed on both sides of the top of the movable frame 3. The hydraulic cylinders 4 adopt a dual-cylinder synchronous design to ensure that the force on both sides is uniform during the lifting and lowering of the movable frame 3, and to avoid the movable frame 3 tilting. The extension and retraction stroke of its drive end can be precisely controlled. The descent distance of the movable frame 3 is adjusted according to the soil depth required for replanting. After the soil is taken and the fertilizer is mixed, the hydraulic cylinders 4 drive the movable frame 3 to rise and reset quickly, creating conditions for the movement and positioning of the seed box 28 and soil backfilling. Its stable power output can adapt to the operation requirements under complex field road conditions, and can ensure the stability of the lifting and lowering of the movable frame 3 even in bumpy environments.

[0031] Furthermore, several short shafts 11 are evenly and movably installed on the inner top of the movable frame 3. These short shafts 11 are connected to the movable frame 3 via bearings and can rotate flexibly. Their number corresponds one-to-one with the soil sampling chambers 5, providing independent rotating shafts for power transmission. This ensures that the rotating shafts 7 within each soil sampling chamber 5 receive stable rotational power, preventing the overall operation from being affected by a single component failure. The bottom of each short shaft 11 is movably mounted with an outer cylinder 12 via a universal joint. The universal joint has multi-angle transmission capabilities, adapting to angular changes during the movement of the soil sampling chambers 5. This ensures that the rotational power of the short shafts 11 can be flexibly transmitted to the outer cylinder 12. Even if the soil sampling chambers 5 move inward or outward simultaneously, the continuity of power transmission will not be affected. The outer cylinder 12 has a hollow structure, and its length is adapted to the soil sampling chambers. The lifting stroke of the soil chamber 5 provides extension and retraction space for the inner rod 13. The top of the rotating shaft 7 is movably mounted with the inner rod 13 via a universal joint, and the ends of the inner rod 13 are movably mounted inside the corresponding outer cylinder 12. The inner rod 13 can freely extend and retract within the outer cylinder 12. With the angle compensation of the universal joint, it is ensured that the power connection between the rotating shaft 7 and the outer cylinder 12 remains stable during the adjustment of the spacing or lifting of the soil chamber 5, and the power will not be interrupted due to changes in distance or angle deviation. Keyways 14 are provided on both sides of the inner wall of the outer cylinder 12. The keyways 14 are long strip-shaped grooves opened along the length of the outer cylinder 12. Their dimensions are precisely matched with the spline 15, providing sliding guidance for the spline 15. At the same time, through the interlocking action of the keyway and the spline, the rotation of the outer cylinder 12 is controlled. The power is transmitted to the inner rod 13, ensuring no relative slippage during power transmission. Both ends of the inner rod 13 are fixedly equipped with splines 15, and the outer ends of the splines 15 are movably positioned inside the corresponding side keyways 14. The splines 15 and keyways 14 form a sliding connection structure, realizing power transmission between the outer cylinder 12 and the inner rod 13, while also allowing the inner rod 13 to extend and retract along its length within the outer cylinder 12. This meets the distance adjustment requirements between the inner rod 13 and the outer cylinder 12 when the soil extraction chamber 5 moves, ensuring compatibility between power transmission and mechanism movement. Transmission gears 16 are fixedly installed on the outer diameter of the short shaft 11, and the inner ends of the connected transmission gears 16 are meshed together. The transmission gears 16 adopt a module-matched design, achieving synchronous power transmission through gear meshing. (Middle section...) When the short shaft 11 rotates, it drives the adjacent transmission gear 16 to rotate in sequence, ensuring that all short shafts 11 rotate at the same speed, thereby making all rotating shafts 7 rotate synchronously, ensuring the consistency of multiple sets of soil sampling, soil crushing, and fertilizer mixing operations. The first motor 17 is fixedly installed at the top center of the movable frame 3, and the drive end of the first motor 17 is fixedly installed at the top of the middle short shaft 11. The first motor 17 is the power source. By driving the middle short shaft 11 to rotate, and through the meshing transmission of the transmission gear 16, it drives all short shafts 11, outer cylinder 12, inner rod 13 and rotating shaft 7 to rotate synchronously. Its output power can be adjusted according to the soil hardness, ensuring that the soil crushing drill bit 10 can effectively crush soil of different textures, while providing sufficient power for the spiral guide vane 9 to transport soil and the mixing rod 8 to mix fertilizer.

[0032] Furthermore, an adjusting shaft 18 is movably installed on the other side of the inner bottom of the movable frame 3. The adjusting shaft 18 is connected to the movable frame 3 through bearings and can rotate smoothly. The arc-shaped groove 19 on its surface provides a guide trajectory for the movement of the soil-taking chamber 5. It is the core component for adjusting the replanting spacing. The rotational motion converts the circular motion into the linear motion of the soil-taking chamber 5. Several arc-shaped grooves 19 are evenly opened on the outer diameter of the adjusting shaft 18, and the pitch of the arc-shaped grooves 19 gradually increases from the center to both sides. The arc-shaped grooves 19 adopt a symmetrical spiral design, with the pitch gradually increasing from the center to both sides. When the adjusting shaft 18 rotates, the arc-shaped grooves 19 drive the soil-taking chamber 5 to move through the round-headed pins 20. Due to the gradual change in pitch, all soil-taking chambers 5 can move synchronously inward or outward at equal distances, ensuring uniform adjustment of the replanting spacing. There is no need to adjust each soil-taking chamber 5 individually. The rear ends of the soil-taking chambers 5 are all fixed. A round-headed pin 20 is fixedly installed, and the ends of the round-headed pin 20 are movably set inside the corresponding side arc-shaped groove 19. The round-headed pin 20 adopts a spherical end design, which has a small contact area with the inner wall of the arc-shaped groove 19 and low friction. It can slide smoothly when the arc-shaped groove 19 rotates, driving the soil-taking chamber 5 to move along the inner bottom of the movable frame 3. Its fixed position on the rear side of the soil-taking chamber 5 ensures that the soil-taking chamber 5 is balanced when moving and avoids tilting. A second motor 21 is fixedly installed on one side of the bottom of the movable frame 3, and the drive end of the second motor 21 is fixedly installed on one end of the adjusting shaft 18. The second motor 21 provides power for the rotation of the adjusting shaft 18. Its forward and reverse rotation can control the soil-taking chamber 5 to gather inward or spread outward. By controlling the rotation angle of the motor, the replanting spacing can be precisely adjusted to adapt to the replanting needs of different sugarcane varieties and different planting densities. It is easy to operate and has high adjustment accuracy.

[0033] Furthermore, each fertilizer inlet pipe 23 is fixedly equipped with a switch valve 24 on its outer diameter. The switch valve 24 is used to control the opening and closing of the fertilizer inlet pipe 23. All switch valves 24 can be opened or closed simultaneously according to the operation requirements to ensure that the timing of fertilizer feeding is precisely connected with the fertilizer-soil mixing process, avoiding premature fertilizer introduction that may lead to clumping or waste. The valve structure has good sealing performance to prevent fertilizer from adhering to the valve after getting damp, thus affecting the opening and closing effect. A cam 26 is fixedly installed on the outer diameter of the middle outer cylinder 12. The cam 26 rotates synchronously with the outer cylinder 12. Its eccentric structure design ensures that during rotation... Intermittent impacts occur between the cam 26 and the pad 27, causing the fertilizer box 22 to vibrate through the impact force. The cam 26 is made of wear-resistant metal to ensure that it is not easily deformed after long-term impact, thus ensuring the stability of the vibration feeding. The pad 27 is fixedly installed on one side of the middle of the fertilizer box 22. The pad 27 is made of elastic material and is fixed on the side of the fertilizer box 22 near the cam 26 to bear the impact force of the cam 26, converting the rotational force into the vibration power of the fertilizer box 22. At the same time, the elastic material can buffer the impact force, prevent the fertilizer box 22 from being damaged by long-term impact, and extend the service life of the equipment.

[0034] Furthermore, fixed rods 29 are fixedly installed at both ends of the seed box 28. The fixed rods 29 are used to connect the seed box 28 and the slider 30, transferring the weight of the seed box 28 to the slider 30, while ensuring that the seed box 28 moves synchronously with the slider 30. Its rigid structure design prevents the seed box 28 from deforming during movement, ensuring the stability of the distribution trough 33 and the discharge pipe 36. The bottom of the fixed rods 29 is fixedly installed with sliders 30. The sliders 30 are adapted to the slide grooves 31 of the frame 1 and can slide smoothly along the slide grooves 31, driving the seed box 28 to move laterally. The smooth design of its bottom reduces the friction with the slide grooves 31, ensuring that the seed box 28 moves lightly and smoothly without jamming. Slide grooves 31 are opened on both sides of the frame 1, and the bottom of the sliders 30 is movably set inside the corresponding side slide grooves 31. The slide grooves 31 provide the sliders 30 with The moving guide trajectory limits the movement direction of the seed box 28 to the lateral direction, ensuring that the feed pipe 36 can accurately align with the pit excavated by the soil sampling cylinder 6 when the seed box 28 moves. The length of the chute 31 is adapted to the moving stroke of the seed box 28 to meet the positioning requirements under different replanting intervals. Both sides of the movable frame 3 are movably installed with connecting rods 32, and the ends of the connecting rods 32 are movably set on the top side of the corresponding slider 30. The connecting rods 32 are movable connection structures, with one end hinged to the movable frame 3 and the other end hinged to the slider 30, forming a linkage mechanism. When the movable frame 3 rises or falls, the slider 30 is driven to move along the chute 31 through the pushing and pulling action of the connecting rods 32, realizing the linkage between the seed box 28 and the movable frame 3, ensuring that the sowing time and the pit positioning are accurately matched, eliminating the need for manual operation of the seed box 28 and improving the degree of automation of the operation.

[0035] Furthermore, a third motor 38 is fixedly installed on one side of the middle portion of the seed box 28, and one end of the central movable shaft 37 is fixedly installed on the drive end of the third motor 38. The third motor 38 provides power for the rotation of the movable shaft 37, and its output speed is stable, ensuring that the rotating disk 34 rotates at a uniform speed, realizing continuous quantitative sowing of the seed material. The sowing speed can be controlled by adjusting the motor speed, adapting to the moving speed of the device, and avoiding missed sowing or over-sowing. The other end of the movable shaft 37 extends to the outside of the seed box 28 and is fixedly installed with a synchronous wheel 39. The movable shaft 37 is used to mount the rotating disk 34 and transmit rotational power. Its structure, which runs through the distribution trough 33, ensures the stable rotation of the rotating disc 34. The synchronous wheel 39 is fixed at the end of the movable shaft 37, providing a mounting carrier for the synchronous belt 40 and ensuring that all movable shafts 37 rotate synchronously. The outer diameters of the synchronous wheels 39 are connected by the synchronous belt 40, which is made of high-strength wear-resistant material. Through meshing with the synchronous wheels 39, the synchronous belt 40 drives all movable shafts 37 to rotate at the same speed, thereby making all rotating discs 34 rotate synchronously. This ensures that the sowing rhythm of multiple sets of feeding pipes 36 is uniform, and that the replanting spacing is even, avoiding uneven sowing due to differences in the rotation speed of a single rotating disc 34.

[0036] Furthermore, a suspension frame 41 is fixedly installed at the front end of the frame 1. The suspension frame 41 adopts a connection structure that conforms to industry standards, which is used to quickly connect and fix the device to a tractor or other mobile equipment. Its high-strength material design can withstand the overall weight of the device, ensuring a stable connection during mobile operation without the risk of falling off. At the same time, the connection method is convenient, facilitating the installation and disassembly of the equipment. Anti-slip rollers 42 are movably installed on both sides of the bottom end of the frame 1. The anti-slip rollers 42 have anti-slip textures and are installed on both sides of the bottom end of the frame 1 to support the overall weight of the device and facilitate the movement of the device in the field. Its anti-slip design prevents slippage when operating on muddy or rugged roads, ensuring the stability of the device's movement. The movable installation design of the rollers allows the device to turn flexibly and adapt to different field operation routes.

[0037] Working principle:

[0038] First, the device is connected and fixed to a tractor or other mobile equipment via the suspension bracket 41. Fertilizer is poured into the fertilizer box 22, and sugarcane seed is placed into the seed box 28. One of the sugarcane seeds will fall into the receiving trough 35. The second motor 21 drives the adjusting shaft 18 to rotate, which in turn drives the arc-shaped groove 19 on the adjusting shaft 18 to rotate. When the arc-shaped groove 19 rotates, it will drive all the soil-taking chambers 5 to move through the round-headed pin 20. Since the spiral of the arc-shaped groove 19 gradually increases from the middle to both sides, all the soil-taking chambers 5 will move inward or outward at equal intervals, which makes it convenient to adjust the replanting spacing as needed. Then, all the discharge pipes 36 are aligned with each soil-taking chamber. Below the cylinder 6, after completion, the hydraulic cylinder 4 is activated, driving the movable frame 3 to descend, causing all the soil sampling cylinders 6 at the bottom of the soil sampling chambers 5 to extend into the ground. Simultaneously, the first motor 17 is activated, driving the central short shaft 11 to rotate. The transmission gear 16 then drives all the transmission gears 16 and the short shaft 11 to rotate. As the short shaft 11 rotates, it drives all the outer cylinders 12 to rotate via the universal joint. The spline 15 and keyway 14 then limit the rotation of all the inner rods 13 and the rotating shaft 7, thereby driving all the soil-breaking drill bits 10 to rotate. The rotating soil-breaking drill bits 10 will then push the soil inside the sampling cylinder 6... The soil is broken up, and the rotation of the rotating shaft 7 also drives the spiral guide vane 9 to rotate, conveying the broken soil upwards into the soil extraction chamber 5. Meanwhile, the rotation of the central outer cylinder 12 also drives the cam 26 to rotate. The rotating cam 26, in conjunction with the pad 27 and spring rod 25, causes the fertilizer tank 22 to vibrate rapidly. At this time, all the switch valves 24 are opened, allowing the fertilizer in the fertilizer tank 22 to be introduced into the soil extraction chamber 5 through the fertilizer inlet pipe 23. The rotation of the rotating shaft 7 also drives the mixing rod 8 to rotate, thoroughly mixing the fertilizer and soil. After completion, the hydraulic cylinder 4 controls the movable frame 3 to rise and reset. As the movable frame 3 rises, it drives the connecting rod... One end of 32 moves along with the connecting rod, causing the other end of 32 to pull the slider 30 inward, thereby pulling the seed box 28 to move so that the discharge pipe 36 at the bottom of the seed box 28 is aligned with the pit opened by the soil sampling cylinder 6. At this time, the third motor 38 is started, and the movable shaft 37 is driven to rotate through the third motor 38. Using the transmission of the synchronous wheel 39 and the synchronous belt 40, all the rotating disks 34 are driven to rotate. The rotating disks 34 rotate the sugarcane seed in the receiving trough 35 to the bottom, so that it enters the pit along the discharge pipe 36. Finally, the first motor 17 drives the outer cylinder 12 to reverse, and the soil in the soil sampling cylinder 6 is refilled into the pit.
