Description

Technical Field

[0001] This invention relates to the field of agriculture, and more particularly to the field of ginger cultivation technology, specifically to an electrically driven ginger bud-harvesting planter and its usage method. Background Technology

[0002] Ginger planting has specific agronomical requirements for seed tuber treatment: First, the ginger must be cut or broken into appropriately sized tubers with plump buds; second, during planting, the buds (sprouting tips) of the tubers must be facing upwards or in a specific direction to ensure uniform emergence and robust seedlings. Currently, in actual production, these operations are almost entirely done manually. Manual seed collection requires skilled workers to identify the buds and divide the tubers into sections, while placing the tubers requires bending over and placing them one by one in the planting furrow, adjusting their orientation. This is extremely labor-intensive, with each person only able to complete about 0.5–1 acre of work per day, and prolonged repetitive operations easily lead to lumbar muscle strain. More importantly, manual placement makes it difficult to ensure the uniformity of bud orientation, resulting in a high rate of orientation deviation, which directly affects the emergence rate and later population uniformity, leading to missing or weak seedlings, and ultimately, yield losses.

[0003] To address the aforementioned issues, in recent years some research institutes and enterprises have attempted to develop simple ginger planting auxiliary devices or semi-automatic seeders. Existing technical solutions mostly employ methods such as vibration seed delivery, grooved wheel seed metering, or manual seed placement, but they generally suffer from the following technical shortcomings: Firstly, there is a lack of single-seed directional seed extraction technology. Ginger seed tubers are irregular in shape, have rough surfaces, and their buds are highly concealed. Existing mechanical or pneumatic seed extraction mechanisms have difficulty in stably grasping individual seed tubers and accurately identifying the orientation of the scale buds, which easily leads to missed extractions, duplicate extractions, or damage to the buds, resulting in poor sowing uniformity.

[0004] Secondly, the seed placement mechanism cannot achieve directional and orderly delivery. Most schemes simply place the seed blocks randomly into the seed furrows, and then rely on manual soil covering for rough arrangement. The qualified rate of scale bud orientation is less than 70%, which is far below the agronomic requirement (≥90%), seriously affecting the uniformity of field growth in the later stage.

[0005] Third, it has poor adaptability and is prone to damaging seeds. Existing seed metering devices are sensitive to fluctuations in seed block size, requiring frequent adjustments. Furthermore, rigid contact can easily cause seed block breakage or mechanical damage to buds, reducing germination viability after sowing and increasing the risk of seedling loss.

[0006] In addition, the few existing fully automatic seeder prototypes mostly use hydraulic or chain drives, which are bulky, energy-intensive, and difficult to achieve precise electro-hydraulic coordinated control. They cannot adjust the seed picking force and seed placement angle in real time according to the physical characteristics of ginger seed pieces, thus limiting the further improvement of seeding accuracy and work efficiency.

[0007] In summary, existing ginger planting equipment still has significant technological gaps in terms of seed extraction accuracy, scale bud orientation control, single-seed planting reliability, and non-destructive treatment of seed blocks, making it difficult to meet the urgent needs of large-scale, standardized ginger cultivation for efficient and high-precision mechanized planting. Summary of the Invention

[0008] To address the shortcomings of existing technologies, this invention provides an electrically driven ginger soft-sprouting and seeding machine, a seeding equipment that integrates soft seed extraction, bud orientation recognition, and orderly seed placement, thereby promoting the mechanization of the entire ginger planting process.

[0009] The present invention is achieved through the following technical solution: an electric-driven ginger bud-harvesting and straightening planter, comprising a frame connected to the machine, a seed box located on the frame for sequential seed entry, a vibrating plate, a seed-harvesting device for maintaining flexible and controlled seed harvesting, a roller-type bud-straightening device for precisely adjusting and conveying the ginger seed scales and buds, and a sowing device for maintaining posture and single-seed sowing. One end of the vibrating plate is hinged to the frame, and the seed-harvesting device includes a cam that drives the vibrating plate to rotate.

[0010] In use, this invention automates the entire process of ginger seed feeding, from dispersed feeding to scale and bud alignment, and finally to fixed-position single-seed sowing by setting up a vibrating plate, a seed picking device with a cam, a roller bud alignment device, and a sowing device. The cam-driven vibrating plate can prevent ginger seed from accumulating and clogging, and maintain the continuity of seed picking; the roller bud alignment device can actively adjust the orientation of the scale and bud during transportation; and the posture-maintaining sowing device ensures that the ginger seed enters the soil in the correct posture, significantly improving the uniformity of sowing and the uniformity of seedling emergence.

[0011] Preferably, the seed-taking device includes several brush rollers arranged circumferentially and connected by a chain drive mechanism. The cam is connected to the brush roller located at the lower end of the vibrating plate, and the remaining brush rollers cooperate with the frame to transport the ginger seed into the roller-shaped budding device.

[0012] In use, this preferred solution employs a chain drive mechanism to connect multiple brush rollers, with a cam installed on the brush roller at the lower end of the vibrating plate. The remaining brush rollers work together, and the flexible bristles of the brush rollers contact the ginger seeds, which can control the amount of seeds taken (preventing multiple seeds from overlapping) and greatly reduce the risk of damage to ginger sprouts. The chain drive ensures the synchronization of each roller, resulting in a compact and reliable structure.

[0013] Preferably, the roller budding device includes two sets of drive rollers. Each drive roller set includes a thin hollow roller and a coarse hollow roller connected by a chain. The thin hollow roller, with a diameter smaller than that of the coarse hollow roller, is located at the top of the coarse hollow roller. The two coarse hollow rollers are meshed by two drive gears. The circumferential surfaces of the two coarse hollow rollers are provided with spiral lines with opposite directions of rotation. A channel for the movement of the ginger seed is formed between the two sets of drive rollers.

[0014] In this preferred embodiment, the fine hollow rollers are positioned directly above the coarse hollow rollers in the roller-aligning device, and a conveying channel is formed between the two sets of drive rollers. The difference in linear velocity between the fine and coarse rollers causes the ginger seed to automatically move towards the center line of symmetry. Combined with the opposite spiral lines on the surfaces of the two coarse hollow rollers, a lateral pushing effect is generated, forcing the ginger seed scales to gradually rotate to a uniform orientation. This purely mechanical structure does not require sensors to identify the orientation, and is low in cost, highly efficient, and highly adaptable.

[0015] Preferably, the seeding device includes a posture-maintaining slide rail located at the tail end of the two drive roller groups and inclined downwards, a seed discharge port located at the material discharge end of the posture-maintaining slide rail and blocking the posture-maintaining slide rail, the seed discharge port being hinged to the posture-maintaining slide rail, and a seed discharge driving device that drives the seed discharge port to rotate downwards is provided on the posture-maintaining slide rail.

[0016] When this preferred solution is used, the sowing device adopts a downward-sloping posture-maintaining slide and a blocking seed discharge port, so that the ginger seeds slide in their original posture and will not roll over; the seed discharge port is controlled to open and close by a drive device to achieve single seed discharge of "one seed at a time", which avoids the phenomenon of multiple seeds falling at the same time or empty discharge, and ensures accurate plant spacing.

[0017] Preferably, the seed outlet is hinged to the posture-maintaining slide via a hinge located on the bottom surface, and the seed dispensing drive device includes a seed dispensing cylinder, with both ends of the seed dispensing cylinder hinged to the posture-maintaining slide and the seed outlet, respectively.

[0018] In this preferred embodiment, the seed dispensing port is hinged to the bottom surface and driven by the seed dispensing cylinder. The hinged connection makes the seed dispensing port flexible to open and close and has good sealing performance. The cylinder responds quickly and can achieve millisecond-level switching action, which can meet the needs of high-speed operation. It also has a simple structure and is easy to control.

[0019] Preferably, the posture-maintaining slide is rotatably connected to the frame via a pin, and the frame is also provided with a support plate located at the lower end of the posture-maintaining slide. An adjusting bolt is fixed on the support plate by a nut, and the adjusting bolt is hinged to the bottom end of the posture-maintaining slide. A pneumatic high-frequency vibrator is also provided on the bottom surface of the posture-maintaining slide.

[0020] In use, the posture-maintaining slide is connected by a pivot pin and equipped with an adjusting bolt, which allows for easy adjustment of the slide's tilt angle to accommodate different ginger seed sizes or sowing depth requirements. The pneumatic high-frequency vibrator prevents the ginger seed from stagnating on the slide, ensuring smooth sliding, and the vibration frequency is adjustable without damaging the ginger seed's posture.

[0021] Preferably, the cam includes a wheel body fixed to the corresponding brush roller shaft, and a plurality of protrusions evenly arranged along the circumference of the wheel body, wherein the side of the protrusions that contacts the vibrating plate is an arc surface.

[0022] In this preferred embodiment, the cam consists of a wheel and several protrusions evenly arranged around the circumference. The side of the protrusion that contacts the ginger seed is an arc surface. The arc surface design reduces the impact stress of the cam on the vibrating plate and avoids scratching the ginger seed. The evenly distributed protrusions enable the vibrating plate to generate stable high-frequency low-amplitude vibration, which is conducive to the even falling of the ginger seed and avoids mechanical jamming.

[0023] Preferably, the cam is connected to the brush roller II, and the chain drive mechanism is also connected to the drain roller shaft located directly below the brush roller II. The chain drive mechanism includes a sampling chain that sequentially connects the brush roller I, brush roller III, and brush roller IV. The brush roller I is located at the upper end of the vibrating plate, and the brush roller III is located below the side of the brush roller I. The brush roller I, brush roller III, and the frame form an inclined downward channel. The seed collection chain is also connected to a support roller located directly below the brush roller I, and the brush roller IV located outside the seed collection chain is provided between the support roller and the brush roller III.

[0024] In use, this preferred solution specifically defines the arrangement of brush rollers I-IV, the drain roller shaft, and the support roller, forming a multi-level guiding and flow control channel. Brush roller II drives the cam, and brush rollers I and III form a downward-sloping single-layer channel. The support roller and brush roller IV further constrain the ginger seed path, and the drain roller shaft serves as an auxiliary guide. This layout allows the ginger seed to be automatically laid out in a single layer and transported in an orderly manner under the combined action of gravity and the roller group, preventing stacking and leakage. Furthermore, the flexible bristles of all brush rollers fully wrap the ginger seed, maximizing the protection of the ginger sprouts.

[0025] Preferably, the frame has four mounting points arranged in a rectangular shape, and the two upper mounting points are each connected to a pull rod.

[0026] In this preferred design, the frame has four rectangularly arranged attachment points, with the upper two attachment points connected to tie rods, allowing for three-point or four-point suspension with tractors or other towing implements. The tie rods cushion the vertical bumps during operation, ensuring overall machine stability, while also facilitating quick attachment and dismounting, thus improving field transfer efficiency.

[0027] A method for using an electrically driven ginger sprouting and sowing machine includes the following steps: a. After the ginger seeds are placed in the seed box, they slide continuously into the seed-collecting device under the guidance of the sliding plate. The AC geared motor I rotates clockwise, driving the brush roller II, roller shaft, and brush roller IV to rotate synchronously clockwise through the sampling sprocket, while brush roller I and brush roller III rotate counterclockwise. During the clockwise rotation of brush roller II, the cam fixedly installed at its shaft end rotates synchronously. The cam periodically strikes the vibrating plate, causing the vibrating plate to vibrate regularly in the up and down direction, thus promoting the ginger seeds to fall evenly and continuously into the device. With the coordinated counter-rotation of brush rollers I and II, brush rollers III and IV, and the auxiliary guiding effect of the roller shaft, the ginger seeds fall in an orderly, single-layer flat manner within the frame, eventually falling smoothly into the working area of ​​the roller bud-correcting device, thus completing the seed-taking process. A small number of ginger seeds can fall controllably into the roller bud-correcting device under the guidance of brush roller II and the drain roller shaft. The soft bristles of the brush rollers can effectively protect the ginger buds during the seed-taking process, greatly reducing damage. b. When ginger seeds enter the roller budding device, in the working area between the fine hollow rollers and the coarse hollow rollers, the AC geared motor II rotates counterclockwise, driving the two sets of fine and coarse hollow rollers to rotate via a chain. Since the angular velocities of the fine and coarse hollow rollers are consistent, and the fine hollow rollers have a smaller diameter, their linear velocity is higher than that of the coarse hollow rollers. The speed difference between the fine and coarse hollow rollers causes the ginger seeds to move closer to the symmetrical center line area of ​​the hollow rollers. With the help of the left and right spiral lines with opposite directions of rotation set on the surface of the two coarse hollow rollers, the orientation of the ginger seed scales is gradually adjusted to be consistent as it moves closer to the symmetrical center line area. It is then conveyed forward with the rotation of the rollers until it falls smoothly into the posture-maintaining slide of the sowing device. c. When the ginger seed falls from the tail end of the coarse hollow roller into the posture-maintaining slide, under the combined action of the inclined surface of the slide and the pneumatic high-frequency vibrator, the ginger seed can slide smoothly and steadily to the seed discharge port. Under the command of the control system, the piston rod of the cylinder retracts, driving the seed discharge port to open around the hinge point; after the ginger seed is discharged, the piston rod extends, causing the seed discharge port to close quickly, thus completing the single seed sowing operation cycle.

[0028] The beneficial effects of this invention are as follows: This solution realizes a complete operation process from seed collection, bud alignment to sowing. In the seed collection stage, cam vibration and brush roller rotation are used to achieve flexible quantity control. In the bud alignment stage, speed difference and reverse spiral are used to achieve automatic bud alignment. In the sowing stage, tilting slide + vibrator + pneumatic seed outlet are used to achieve posture-preserving single-seed sowing. This invention realizes a sowing equipment that integrates flexible seed collection, bud orientation recognition and orderly seed placement, thereby promoting the mechanization of the entire ginger planting process.

[0031] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0032] See attached document Figure 1-3 This invention discloses an electrically driven ginger bud-harvesting and straightening planter and its usage method. The planter includes a seed box 10, a seed-harvesting device 20 for flexible and controlled seed collection, a roller-type bud-straightening device 30, a sowing device 40 for posture-preserving and single-seed sowing, a power unit 50, and a frame 64. The seed box 10 is installed above the seed-harvesting device 20, and the roller-type bud-straightening device 30 is installed at the seed outlet of the seed-harvesting device 20. The sowing device 40 is installed directly behind the roller-type bud-straightening device 30, and the power unit 50 is fixedly installed on the frame 64, providing power and control for the entire machine.

[0033] Specifically, the seed box 10 has a sliding seed plate 11 at the bottom, which extends and inserts into the seed-taking device 20 to guide and supply the ginger seeds. The frame has a vibrating plate located at the lower end of the sliding seed plate and receiving the ginger seeds. One end of the vibrating plate is hinged to the frame, and the other end is connected to a limiting rod. The frame has an arc-shaped limiting hole for the limiting rod to be inserted.

[0034] The seed collection device 20 includes a chain drive mechanism, which includes a brush roller II 24 and brush rollers I 21, III 26, and IV 27 connected by a sampling chain. Each brush roller is fixedly supported by bearing seats installed at both ends of the roller shaft 25. A cam 22 is mounted on the shaft end of brush roller II 24. The cam 22 is located at the lower end of the vibrating plate. When the cam 22 rotates, it periodically strikes the vibrating plate 23 to generate vibration. The cam includes a wheel body fixed to the corresponding brush roller shaft and a number of protrusions evenly arranged along the circumference of the wheel body. The side of the protrusion that contacts the vibrating plate is an arc surface.

[0035] The chain drive mechanism is also connected to a drain roller shaft located directly below the brush roller II. The brush roller I is located at the upper end of the vibrating plate, and the brush roller III is located below the side of the brush roller I. The brush roller I, brush roller III, and frame form an inclined downward channel. The seed picking chain is also connected to a support roller located directly below the brush roller I. Between the support roller and the brush roller III, there is a brush roller IV located on the outside of the seed picking chain.

[0036] The roller budding device 30 is installed directly below the seed-taking device 20 and includes two sets of drive rollers. The drive roller sets include a thin hollow roller 31 and a coarse hollow roller 32 connected by a chain. The thin hollow roller 31 is located above the coarse hollow roller 32. The roller shafts 36 of both the thin hollow roller 31 and the coarse hollow roller 32 pass through the fixed plate 35. The two ends of the roller shafts 36 are fixedly supported by bearing seats to ensure smooth operation of the hollow rollers. A drive gear 34 is installed at one end of the roller shaft of the coarse hollow roller 32 to transmit power. The surfaces of the two coarse hollow rollers 32 are fixedly installed with spirals 33 with opposite left and right rotation directions, which can adjust the orientation of the ginger seed during the conveying process. A channel for the ginger seed to move is formed between the two sets of drive rollers.

[0037] The sowing device 40 is installed at the rear of the roller budding device 30. It includes a posture-maintaining slide 41 and a seed discharge port 42. The posture-maintaining slide 41 and the seed discharge port 42 are hinged and fixed by a hinge 48. A pin sleeve 45 is fixed on the back of the posture-maintaining slide 41. The pin is hinged and fixed to the corresponding pin sleeves on both sides of the frame 64 by a pin shaft, so that the entire device can rotate around the hinge point.

[0038] A pneumatic high-frequency vibrator 43 and a cylinder 44 are sequentially installed on the back of the posture-maintaining slide 41. The two ends of the cylinder 44 are respectively hinged to the posture-maintaining slide 41 and the seed discharge port 42. The opening and closing of the seed discharge port 44 is controlled by its telescopic movement. A support plate 46 and an adjusting bolt 47 are provided between the pin sleeve 45 and the pneumatic high-frequency vibrator 43. The support plate 46 is fixedly connected to the frame 64. The adjusting bolt 47 is connected to the support plate by a nut. The top of the adjusting bolt is hinged to the posture-maintaining slide. The working tilt angle of the sowing device 40 can be changed by adjusting the bolt 47. With the high-frequency micro-amplitude vibration generated by the pneumatic high-frequency vibrator 43, the ginger seeds can be ensured to slide smoothly and steadily in the posture-maintaining slide 41.

[0039] The core component of the power unit 50 is the battery 56, which serves as the sole power source for the entire machine. It is mounted above the battery mounting plate 57 along with the inverter 55. The air pump 51 is fixed to the battery mounting plate 57 using a flexible shock-absorbing method. Its output compressed air powers the cylinder 44 and the pneumatic high-frequency vibrator 43, enabling orderly seeding. The battery mounting plate 57 is rigidly connected to the frame 64. The distribution box 54 is fixedly mounted above the battery 56 and inverter 55, integrating electrical equipment and control units to achieve power distribution and operational process control for the entire machine. AC geared motors II 52 and I 53 are bolted to corresponding positions on the frame 64. They transmit power to the roller budding device 30 and the seed-taking device 20 respectively via a sprocket and chain drive mechanism, coordinating seed taking and budding operations. AC geared motor I 53 is connected to the chain drive mechanism, driving the brush rollers I, III, IV, II, and the drain roller shaft synchronously.

[0040] The support frame 60 mainly includes a frame 64, which is a one-piece frame structure made by welding. The frame 64 has two upper hanging points 61 on the upper part and two lower hanging points 63 on the lower part, arranged in a rectangular pattern. The upper hanging points 61 are connected to the tie rod 62 by hinges to form an adjustable tilt mechanism to adjust the working tilt angle of the entire machine.

[0041] The electric-driven, low-damage, high-efficiency ginger bud-planting machine of this application realizes full mechanization of ginger seed collection and placement, significantly reducing reliance on manual operation, effectively reducing labor intensity, and greatly improving planting efficiency.

[0042] How to use an electric-driven ginger sprout extractor: During operation, the pull rod 62 and the lower hanging point 63 are respectively hinged to the corresponding hanging points of the rear suspension device of the machine. By adjusting the length of the pull rod 62, the working tilt angle of the roller budding device 30 and the sowing device 40 can be changed, thereby adjusting the conveying time and falling state of the ginger seeds in the coarse hollow roller 32 and the posture-maintaining slide 41 to adapt to the agronomic requirements of different operating speeds and plant spacing.

[0043] The power output from battery 56 is divided into two paths: one path directly supplies power to the electrical equipment and control unit in distribution box 54, and the other path is connected to inverter 55. When inverter 55 is started, it converts 24V DC power to 220V AC power through voltage conversion, thereby providing working power to AC geared motor I 53, AC geared motor II 52 and air pump 51.

[0044] After the ginger seeds are placed in the seed box 10, they slide continuously into the vibrating plate inside the seed-taking device 20 under the guidance of the sliding plate 11. The AC reduction motor I 53 rotates clockwise, driving the brush roller II 24, roller shaft 25 and brush roller IV 27 to rotate clockwise synchronously through the seed-taking chain. Meanwhile, brush roller I 21 and brush roller III 26 rotate counterclockwise. During the clockwise rotation of brush roller II 24, it drives the cam 22 fixedly installed at its shaft end to rotate synchronously. The cam 22 periodically strikes the vibrating plate 23, causing the vibrating plate to vibrate regularly in the up and down direction, which promotes the ginger seeds to fall evenly and continuously into the device. Under the coordinated counter-rotation of brush roller I 21 and brush roller II 24, brush roller III 26 and brush roller IV 27, and the auxiliary guiding effect of roller shaft 25, the ginger seeds fall in an orderly, single-layer flat state in the device, and finally fall smoothly into the working area of ​​the roller budding device 30, thus completing the seed-taking process. The ginger seed enters the working area between the fine hollow rollers 31 and the coarse hollow rollers 32 in the roller budding device 30. The AC geared motor II 52 rotates counterclockwise, driving the left hollow rollers of the fine hollow rollers 31 and coarse hollow rollers 32 to rotate synchronously counterclockwise through the sprocket and chain transmission mechanism. Under the meshing transmission of the transmission gear 34 and the cooperation of the sprocket and chain transmission mechanism, the right hollow rollers of the fine hollow rollers 31 and coarse hollow rollers 32 are driven to rotate synchronously clockwise. Since the sprockets have the same number of teeth, the fine hollow rollers 31 and coarse hollow rollers 32 rotate synchronously. The angular velocities of the coarse hollow rollers 32 are kept consistent, while the diameter of the fine hollow rollers 31 is smaller and its linear velocity is higher than that of the coarse hollow rollers 32. The speed difference between the fine hollow rollers 31 and the coarse hollow rollers 32 causes the ginger seed to move closer to the symmetrical center line area of ​​the hollow rollers. With the help of the left and right spiral lines 33 with opposite rotation directions set on the surface of the coarse hollow rollers 32, the orientation of the ginger seed scales and buds is gradually adjusted to be consistent as it moves closer to the symmetrical center line area. It is then conveyed forward with the rotation of the rollers until it falls smoothly into the posture-maintaining slide 41 of the sowing device 40. To maintain transmission stability during long-term operation, the hollow rollers and transmission gear 34 are reinforced by a fixing plate 35. The roller shaft 36 passes through the mounting hole on the fixing plate 35 to form a reliable support structure, effectively preventing deviation in the coaxiality of the hollow rollers and roller shaft 36 due to long-term operation.

[0045] The sowing device 40 is hinged to the frame 64 via a pin sleeve 45, allowing the entire device to rotate around the hinge axis. On one hand, the operating angle of the device can be changed by adjusting the adjusting bolt 47; on the other hand, the high-pressure air source supplied by the air pump 51 provides power to the pneumatic high-frequency vibrator 43 and the cylinder 44. When the pneumatic high-frequency vibrator 43 is working, it generates high-frequency micro-amplitude vibration to assist in the smooth transport of ginger seeds. When the ginger seeds fall into the posture-maintaining slide 41, under the combined action of the inclined surface of the slide and the high-frequency micro-amplitude vibration, the ginger seeds can slide smoothly and smoothly to the seed discharge port 42. Under the command of the control system, the piston rod of the cylinder 44 retracts, driving the seed discharge port 42 to open around the hinge point of the hinge 48. After the ginger seeds are discharged, the piston rod extends, causing the seed discharge port 42 to close quickly, thus completing the single-seed sowing operation cycle. If ginger seed blockage occurs in the sliding slide 41, the control system will immediately interrupt the power input of AC geared motor II 52 and AC geared motor I 53, and increase the air pressure supply to the pneumatic high-frequency vibrator 43 to generate higher frequency vibration, thereby increasing the operating frequency of cylinder 44. This linkage control can effectively promote the rapid unblocking and smooth discharge of the blocked ginger seed, ensuring the continuity and reliability of ginger planting operations.

[0046] This invention uses a battery as the power source for the entire machine. One battery pack directly powers the control system, while the other is converted into stable AC power by an inverter, which then powers the air pump and the AC geared motor.

[0047] The AC geared motor drives the sprocket transmission system of the flexible quantity control seed taking device and the roller budding device. By adjusting the speed of the AC geared motor, the seed taking speed of the flexible quantity control seed taking device and the budding efficiency of the roller budding device are matched to each other, so as to avoid ginger seed congestion due to incoordination and thus damage to the ginger seed.

[0048] The air pump generates a high-pressure air source, which is divided into two paths to supply air to the pneumatic high-frequency vibrator and the cylinder, respectively. The pneumatic high-frequency vibrator generates continuous high-frequency vibration on the posture-maintaining single-seed planting device, assisting the ginger seed to slide smoothly and orderly along the posture-maintaining slide. The cylinder, under the coordinated action of the air source and control system, performs regular extension and retraction movements, driving the timed opening and closing of the seed discharge port, ultimately achieving single-seed, precise planting of ginger seeds. This solution eliminates the need for staff to handle seed collection and placement, greatly improving planting efficiency while reducing labor intensity. At the same time, the plant spacing is adjustable, increasing ginger yield.

[0049] After ginger seeds are placed in the seed box, they slide continuously and stably into the flexible, controlled-volume seed-taking device, guided by the sliding plate inside the box. Driven by an AC geared motor, the cam periodically strikes the vibrating plate, causing a small amount of ginger seeds to fall onto the surface of the brush roller and roller shaft. The brush roller and roller shaft are set with specific rotation directions and speeds to achieve controllable distribution of ginger seeds into the roller-shaped bud-aligning device. The soft bristles of the brush roller effectively protect the ginger buds during seed taking, greatly reducing damage. The upper hollow roller of the roller-shaped bud-aligning device has a small diameter, while the lower hollow roller has a large diameter. The coordinated rotation of the upper and lower hollow rollers prevents the ginger seeds from tumbling and falling during orientation adjustment. The lower hollow roller is designed with a specific spiral line, which can adjust the orientation of the ginger seed scales and buds to be consistent while conveying them forward, thereby significantly improving overall operating efficiency while ensuring the bud alignment rate.

9. The electrically driven ginger bud-harvesting and sowing machine according to claim 1, characterized in that: The frame (64) has four hanging points arranged in a rectangle, and the two upper hanging points (61) are each connected to a pull rod (62).

10. The method of using the electric-driven ginger bud-harvesting and sowing machine according to claim 8, characterized in that, Includes the following steps: a. After the ginger seeds are placed in the seed box (10), they continue to slide into the seed-taking device (20) under the guidance of the sliding plate (11). The AC reduction motor I rotates clockwise, driving the brush roller II, roller shaft and brush roller IV to rotate clockwise synchronously through the sampling sprocket, while brush roller I and brush roller III rotate counterclockwise. During the clockwise rotation of brush roller II, the cam (22) fixedly installed on its shaft end rotates synchronously. The cam (22) periodically hits the vibrating plate (23), causing the vibrating plate (23) to produce regular up-and-down vibration, which promotes the ginger seeds to fall into the device evenly and continuously. Under the coordinated counter-rotation of brush roller I and brush roller II, brush roller III and brush roller IV, and the auxiliary guiding effect of the roller shaft, the ginger seeds fall in an orderly, single-layer flat state within the frame (64), and finally fall smoothly into the working area of ​​the roller bud-correcting device (30), thus completing the seed-taking process. A small number of ginger seeds fall controllably into the roller bud-correcting device (30) under the guidance of brush roller II and the drain roller shaft (25). The soft bristles of the brush roller can effectively protect the ginger buds during the seed-taking process, greatly reducing damage. b. When ginger seeds enter the roller budding device (30), the working area between the fine hollow roller (31) and the coarse hollow roller (32) is rotated counterclockwise by the AC geared motor II. The two sets of drive rollers (31) and coarse hollow rollers rotate through the chain. Since the angular velocities of the fine hollow roller (31) and the coarse hollow roller (32) are consistent, and the diameter of the fine hollow roller (31) is smaller, its linear velocity is higher than that of the coarse hollow roller (32). The speed difference between the fine hollow roller (31) and the coarse hollow roller (32) causes the ginger seeds to move closer to the symmetrical center line area of ​​the hollow rollers. With the help of the spiral lines (33) with opposite left and right rotation directions set on the surface of the two coarse hollow rollers (32), the ginger seeds gradually adjust the orientation of their scales and buds to be consistent as they move closer to the symmetrical center line area. They are then conveyed forward with the rotation of the rollers until they fall smoothly into the posture-maintaining slide (41) of the sowing device (40). c. When the ginger seed falls from the tail end of the coarse hollow roller (32) into the posture-maintaining slide (41), under the combined action of the inclined surface of the slide and the pneumatic high-frequency vibrator (43), the ginger seed can smoothly and smoothly slide to the seed discharge port (42). Under the command of the control system, the piston rod of the cylinder (44) retracts and drives the seed discharge port (42) to open around the hinge (48) hinge point. After the ginger seed is discharged, the piston rod extends and the seed discharge port (42) closes quickly, thus completing the single seed sowing operation cycle.
