Abstract
Description
Technical Field
[0001] This utility model relates to the field of agricultural machinery technology, and in particular to a hybrid oil-electric sowing device for Solomon's seal rhizomes suitable for mountainous and hilly areas. Background Technology
[0002] Polygonatum is a plant with important medicinal value, and market demand for it has been steadily increasing in recent years. To meet this demand, expanding the planting area of Polygonatum has become an inevitable trend. Traditional manual sowing methods are inefficient, labor-intensive, and unsuitable for large-scale cultivation. Manual sowing of Polygonatum rhizomes is slow, consuming a significant amount of time and manpower. For large-scale cultivation, the slow pace of manual sowing may cause the optimal planting time to be missed. Manual sowing also makes it difficult to ensure uniformity and depth of sowing, affecting the germination rate and growth quality of Polygonatum. Prolonged bending over during manual labor can easily lead to worker fatigue and physical injury.
[0003] Some traditional seed-planting machinery is primarily designed for seed sowing and may not be suitable for planting the unique rhizomes of Polygonatum. The irregular shape and varying sizes of Polygonatum rhizomes make it difficult for traditional seeders to accurately grasp and sow them. Furthermore, some traditional seeders have high power requirements and energy consumption, increasing planting costs.
[0004] In summary, manual sowing of Polygonatum rhizomes is inefficient, traditional pure electric seeders have limited range in field operations, and fuel-powered seeders are energy-intensive and noisy.

[0024] refer to Figures 1-10As shown, this utility model embodiment provides a hybrid oil-electric Solomon's seal rhizome planting machine, including a walking frame 1, a clutch mechanism 2, a fuel engine 3, an electric motor 4, a first transmission mechanism 5, a second transmission mechanism 6, a third transmission mechanism 7, a sowing device 8, and a furrowing device 9. The clutch mechanism 2 includes a dual clutch 21, a first transmission shaft 22, and a second transmission shaft 23, which are connected through the dual clutch 21. The fuel engine 3 and the electric motor 4 are both mounted on the walking frame 1, and the output end of the fuel engine 3 is connected to the first transmission shaft 22. The drive shaft 22 is connected to the motor 4, and the output end of the motor 4 is connected to the second drive shaft 23. The input end of the first transmission mechanism 5 is connected to the second drive shaft 23, and the output end is connected to the input ends of the second transmission mechanism 6 and the third transmission mechanism 7 respectively. The output end of the second transmission mechanism 6 is connected to the walking drive wheel 12 of the walking frame 1 to drive walking. The sowing device 8 includes a spoon chain seed metering device 81. The output end of the third transmission mechanism 7 transmits power to the spoon chain seed metering device 81 for seed metering. The furrowing device 9 is installed behind the sowing device 8.
[0025] In one embodiment, the walking frame 1 includes a front support 11 and a walking drive wheel 12, the walking drive wheel 12 being mounted on the lower end of the front support 11. The walking frame 1 integrates a dual power source of a fuel engine 3 and an electric motor 4, and can be configured with a lever 24 to control a dual clutch 21. Two operating modes can be achieved via the lever 24: fuel-driven mode: the clutch is engaged, and the fuel engine 3 independently drives the walking and sowing device 8; battery-driven mode: the clutch is disengaged, and the electric motor 4 independently drives the walking and sowing device 8. The walking frame 1 can not only complete sowing operations on different terrains, but the multiple seed spoons 814 in the spoon sowing device 8 can also improve sowing efficiency. To better match the vast differences in shape, size, surface texture, and center of gravity of the Polygonatum odoratum seed blocks, the seed spoons 814 have been completely redesigned.
[0026] In one embodiment, the sowing device 8 includes a seed box 82 and a spoon chain seed metering device 81. The seed box 82 is mounted on the walking frame 1, and the spoon chain seed metering device 81 is mounted inside the seed box 82. The third transmission mechanism 7 is connected to the spoon chain seed metering device 81 in a transmission connection.
[0027] In one embodiment, a lever 24 is mounted on the dual clutch 21 for engaging or disengaging the first drive shaft 22 and the second drive shaft 23.
[0028] In one embodiment, the output end of the fuel engine 3 is connected to the first drive shaft 22 via a pulley drive mechanism, and the output end of the electric motor 4 is connected to the second drive shaft 23 via a pulley drive mechanism.
[0029] In one embodiment, the first transmission mechanism 5, the second transmission mechanism 6, and the third transmission mechanism 7 are all chain drive mechanisms.
[0030] In one embodiment, the first transmission mechanism 5 includes: a first sprocket 51, a second sprocket 52, a first chain 53, and a third transmission shaft 54. The first sprocket 51 is mounted on the second transmission shaft 23, the second sprocket 52 is mounted on the third transmission shaft 54, and the first chain 53 is fitted between the first sprocket 51 and the second sprocket 52.
[0031] In one embodiment, the second transmission mechanism 6 includes a third sprocket 61, a fourth sprocket 62, and a second chain 63. The third sprocket 61 is mounted on the third transmission shaft 54, the fourth sprocket 62 is mounted on the drive wheel 12, and the second chain 63 is fitted between the third sprocket 61 and the fourth sprocket 62. When the third transmission shaft 54 rotates, it drives the third sprocket 61 to rotate. The second chain 63 connects the third sprocket 61 and the fourth sprocket 62, driving the fourth sprocket 62 to rotate, thereby driving the drive wheel 12 forward or backward. This structure allows the generated power to be more fully utilized by the drive wheel, ensuring stable and efficient operation of the seeder. It also ensures the seeder maintains good driving conditions during field operations, guaranteeing that seeds are sown evenly at predetermined intervals and depths.
[0032] In one embodiment, the third transmission mechanism 7 includes: a fifth sprocket 71, a sixth sprocket 72, a third chain 73, a gearbox 74, a seventh sprocket 75, an eighth sprocket 76, and a fourth chain 77. The fifth sprocket 71 is mounted on the third transmission shaft 54, the sixth sprocket 72 is mounted on the input shaft of the gearbox 74, the third chain 73 is fitted between the fifth sprocket 71 and the sixth sprocket 72, the seventh sprocket 75 is mounted on the output shaft of the gearbox 74, the eighth sprocket 76 is mounted on the drive shaft 811 of the spoon-chain seeder 81, and the fourth chain 77 is fitted between the seventh sprocket 75 and the eighth sprocket 76. The rotation of the third transmission shaft 54 drives the fifth sprocket 71 to rotate, the third chain 73 drives the sixth sprocket 72, the gearbox 74 transmits power to the seventh sprocket 75 to rotate, and the fourth chain 77 drives the eighth sprocket 76 to rotate, thereby causing the drive shaft 811 to rotate. By changing the gear of the gearbox 74, the rotation speed can be adjusted, thereby changing the sowing speed and adjusting the spacing between plants of Polygonatum sibiricum. The third transmission mechanism 7's transmission structure design achieves efficient power transmission within the gearbox 74, ensuring the stability and reliability of the coordinated operation between various components of the seeder, thus providing a solid power guarantee for the stable operation and precise sowing of the seeder.
[0033] In one embodiment, the spoon-chain seed metering device 81 includes a drive shaft 811, a driven shaft 812, a transmission chain 813, and seed spoons 814. The transmission chain 813 is mounted on the drive shaft 811 and the driven shaft 812, and a plurality of seed spoons 814 are arranged on the transmission chain 813. When the drive shaft 811 rotates, it drives the transmission chain 813 to rotate, thereby causing the driven shaft 812 to rotate. The seed spoons 814 scoop seeds upward from the seed box 82, and the seeds then enter the seed metering channel and finally fall into the furrow opened by the furrow opener 91, completing the sowing operation.
[0034] Specifically, the overall outline of the Seed Spoon 814 has been enlarged to approximately ten centimeters square: its length, width, and depth have all expanded simultaneously, forming a more spacious container. Whether encountering short, thick, oval-shaped seed tubers, slender, slightly curved spindle-shaped rhizomes, or deformed tubers with uneven surfaces and sharp edges, this enlarged spoon can firmly support them, providing ample support and preventing the seed tubers from protruding halfway or hanging alone. Secondly, the spoon itself features a bold perforation design: a long hole in the center, supplemented by symmetrical flow notches on both sides. These transparent openings not only eliminate excess weight, making the Seed Spoon 814 light and agile, but also allow airflow during movement, reducing shaking; rainwater and loose soil can also drain away smoothly, preventing stagnation. To firmly hold the seed tubers, three directional protrusions are designed inside the spoon: the first is located at the front edge of the spoon bottom, the second on the left side of the spoon wall, and the third on the right side of the spoon wall, forming a triangular embrace with the first two. The three protrusions, though not sharp, form a fence with just the right arc and height, firmly holding the seed block in place during vertical lifting, rapid turns, or bumpy undulations, preventing it from swaying left and right or slipping backward. The sowing speed of the spoon-chain seeder is controlled by adjusting the gearbox 74, thus adjusting the plant spacing of the Polygonatum seeds. The depth of the furrow is adjusted by controlling the height of the furrowing device 9 relative to the ground. When the sowing ground is uneven, the soil covering device re-covers the furrowed soil, and the drive wheels also compact the soil, achieving an automatic soil covering function.
[0035] In one embodiment, the trenching device 9 includes a trencher 91, which is adjustablely mounted on the traveling frame 1. A plurality of trencher 91 fastening screws are evenly mounted on the trencher 91 fixing device, with one trencher 91 fixed to each trencher 91 fastening screw.
[0036] Through the design of the aforementioned transmission mechanism and sowing process, this invention achieves adjustable sowing speed, enabling precise control of plant spacing according to different sowing requirements, while ensuring the stability and efficiency of the sowing process. It provides a reliable sowing solution for agricultural production and has significant innovation and practicality.
[0037] The working principle of this utility model is as follows: Before the operation begins, the operator can manually select either the fuel engine 3 or the electric motor 4 as the power source and adjust the lever 24 of the dual clutch 21 to prevent the power transmission between the electric motor 4 and the fuel engine 3 from affecting each other. The power of the output shaft is divided into two paths through the first transmission mechanism 5 and transmitted to the second transmission mechanism 6 and the third transmission mechanism 7 respectively. The power of the second transmission mechanism 6 is transmitted to the walking drive wheel 12 to realize the walking function of the seeder; the power of the third transmission mechanism 7 is transmitted to the spoon chain seed metering device 81. When the drive shaft 811 rotates, it drives the transmission chain 813 to rotate, thereby causing the driven shaft 812 to rotate. The seed spoon 814 scoops the seeds upward from the seed box 82. The seeds then enter the seed metering canal and finally fall into the furrow opened by the furrow opener 91 to complete the sowing operation.
[0038] As can be seen from the above embodiments, this utility model adopts the technical means of hybrid oil and electric power, multiple transmission mechanisms cooperating to control the travel speed, combining the travel speed with the sowing speed, and the gearbox 74 between the third transmission mechanism 7 and the fifth transmission mechanism controlling the rotation speed of the spoon chain sowing device 8. Therefore, it overcomes the technical problem of low sowing efficiency of traditional Polygonatum sowing machine, and achieves the technical effects of simultaneous sowing of multiple rows, adjustable sowing spacing, and adjustable furrow depth.

The present invention is intended to cover any variations, uses, or adaptations of the invention that follow the general principles of the invention and include common knowledge or customary techniques in the art not disclosed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of the invention are indicated by the claims.
