Description

Technical Field

[0001] This application relates to the field of small agricultural machinery, specifically to an intelligent device for planting mung beans. Background Technology

[0002] Mung beans are highly valued for their nutritional, medicinal, feed, and commercial uses, and are widely used, earning them the nickname "green pearl." As a traditional Chinese food, they have become increasingly popular in various food production and processing industries, particularly during the hot summer months due to their heat-clearing, detoxifying, and diuretic properties. From mung bean soup and cakes to mung bean beverages, these foods are beloved by consumers (and are also highly favored in the skincare industry), thus enjoying a high reputation in both domestic and international markets.

[0003] In related technologies, mung bean cultivation can be carried out by manual laying or by planting vehicle laying. Each method has its advantages and disadvantages. Manual laying is relatively slow and consumes more manpower and material resources, and the working environment of the workers is also harsh. On the other hand, planting vehicles are larger in size, have limited turning and passage, and are more difficult to store and maintain. Summary of the Invention

[0004] This application provides an intelligent device for planting mung beans, which can solve the technical problems in related technologies where manual mung bean planting is slow and consumes a lot of manpower and resources, while planting mung beans by planting vehicle is difficult to handle due to the large size of the planting vehicle, which has limited turning and passage and is difficult to store and maintain.

[0005] In a first aspect, embodiments of this application provide an intelligent device for sowing mung beans, comprising: a frame; a moving mechanism mounted on the frame and connected to a steering mechanism; a tillage-opening composite mechanism including a first driving component and a ditching mechanism connected to the first driving component, the first driving component being mounted at one end of the frame and used to drive the ditching mechanism to descend into the soil or to drive the ditching mechanism to rise out of the soil; a sowing mechanism mounted on the frame, the sowing mechanism including a seed box and a sowing tube communicating with the seed box; and a soil covering mechanism mounted at the end of the frame away from the first driving component, the soil covering mechanism being used to backfill the soil on both sides of the ditch formed after the ditching mechanism has been operated into the sowing ditch to cover the sown seeds.

[0007] In conjunction with the first aspect, in one embodiment, the support frame includes two support plates, a fixed crossbar, and a first rotating rod. The two support plates are spaced apart along a direction perpendicular to the traveling direction of the frame. The two ends of the fixed crossbar are respectively fixed to the two support plates.

The two ends of the first rotating rod are respectively rotatably connected to the two support plates, and the soil-turning wheel is fixed to the first rotating rod. The first rotating rod is connected to a second drive assembly.

[0008] In conjunction with the first aspect, in one embodiment, the two support plates are further connected to a second rotating rod, the second rotating rod being parallel to the first rotating rod and disposed on the side of the first rotating rod biased towards the fixed crossbar. The second drive assembly includes: a second drive mechanism, the output shaft of the second drive mechanism being fixed to the second rotating rod; and a transmission wheel set, the transmission wheel set including a first sprocket fixed to the second rotating rod and a second sprocket fixed to the first rotating rod, the first sprocket and the second sprocket being connected by a transmission chain.

[0009] In conjunction with the first aspect, in one embodiment, the trenching mechanism includes two trenching components, which are spaced apart along a direction perpendicular to the travel direction of the frame and connected by a stabilizing component. The stabilizing component includes a first rod and a second rod, both of which are parallel to the second rotating rod. The first rod and the second rod are connected through the trenching components, and both ends of the first rod are rotatably connected to the two trenching components. Both ends of the second rod are fixed to the two trenching components. The second rod is rotatably sleeved on the outer periphery of the second rotating rod, and the first rod is rotatably connected to the output shaft of the first drive component.

[0010] In conjunction with the first aspect, in one embodiment, each trenching component includes a first segment, a second segment, and a third segment. The first segment is sandwiched between the first rod and the second rod. The second segment is fixed to the end of the first segment near the second rod and forms an angle with the first segment. The third segment is fixed to the end of the second segment away from the first segment, and a soil-breaking blade is fixed to the end of the third segment away from the second segment.

[0011] In conjunction with the first aspect, in one embodiment, the seed box includes a seed-distributing chamber and at least two seed-dropping chambers. The seed-distributing chambers and the seed-dropping chambers are arranged at intervals along a direction perpendicular to the traveling direction of the frame. At least two of the seed-dropping chambers are located on opposite sides of the seed-distributing chamber, and the bottom surface of each seed-dropping chamber is connected to the sowing tube. A seed-distributing disc is installed inside the seed-distributing chamber. The seed-distributing disc has a centrally raised structure, and the center height of the seed-distributing disc is higher than the outer edge height.

[0012] In conjunction with the first aspect, in one embodiment, each seed-dropping cavity has an opening on its bottom surface, and the seed-dropping cavity communicates with the sowing tube through the opening. The sowing mechanism further includes a sowing adjustment component, which includes a third drive component and a drive gear plate connected to the third drive component. The drive gear plate is fixed to the seed-distributing disc. The sowing adjustment component also includes at least two seed-dropping wheels, one of which is rotatably installed in each seed-dropping cavity. The seed-dropping wheel closest to the drive gear plate meshes with the drive gear plate. Each seed-dropping wheel has multiple seed-dropping holes. The third drive component drives the drive gear plate to rotate, thereby causing each seed-dropping wheel to rotate around its own axis, so that the seed-dropping holes are sequentially aligned with the openings, thereby controlling the quantitative seed drop into the sowing tube.

[0013] In conjunction with the first aspect, in one embodiment, the third drive assembly includes: a third drive mechanism, the output shaft of which is connected to a first bevel gear; and a second bevel gear, which meshes with the first bevel gear and is coaxially fixed with the drive gear disk.

The two ends of the two vertical bars are respectively hinged to the ends of the two horizontal bars to form a parallelogram linkage structure. The two front wheels are respectively connected to the two vertical bars; and a servo motor, which is fixed to the frame. The output shaft of the servo motor is fixed with a transmission component, and the two ends of the transmission component are respectively fixed to the two horizontal bars. The servo motor is used to drive the transmission component to rotate, thereby causing the two horizontal bars to generate relative displacement, so that the two vertical bars deflect synchronously, thereby realizing the steering control of the front wheels.

[0015] The beneficial effects of the technical solutions provided in this application include: By integrating the moving mechanism, steering mechanism, tillage and opening mechanism, sowing mechanism, and soil covering mechanism into the frame, the overall volume of the intelligent mung bean sowing device can be reduced. Even on small, irregular plots, the steering mechanism can be used to achieve overall steering of the device. In addition, the first drive component can be used to control the raising and lowering of the ditching mechanism to enter and leave the soil, which, together with the movement of the moving mechanism and the backfilling of the soil by the soil covering mechanism, completes the mung bean sowing operation. This solves the technical problems of the slow speed and high manpower and material consumption of manual mung bean laying in related technologies, and the difficulty of steering, passage and storage and maintenance of planting vehicles due to their large size.

[0019] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present application.

[0020] This application provides an intelligent device for planting mung beans, which can solve the technical problems in related technologies where manual mung bean planting is slow and consumes a lot of manpower and resources, while planting vehicles are difficult to use due to their large size, limited turning and passage, and difficulty in storage and maintenance.

[0021] See Figure 1 The image shows an intelligent mung bean sowing device provided in an embodiment of this application. It may include: a frame 1; a moving mechanism 2, mounted on the frame 1 and connected to a steering mechanism 3; a tillage-opening composite mechanism 4, comprising a first drive component 41 and a furrowing mechanism 42 connected to the first drive component 41, the first drive component 41 being mounted at one end of the frame 1, the first drive component 41 being used to drive the furrowing mechanism 42 to descend into the soil or to drive the furrowing mechanism 42 to rise out of the soil; a sowing mechanism 5, mounted on the frame 1, the sowing mechanism 5 including a seed box 51 and a sowing tube 52 communicating with the seed box 51; and a soil covering mechanism 7, mounted at the end of the frame 1 away from the first drive component 41, the soil covering mechanism 7 being used to backfill the soil on both sides of the furrow formed after the furrowing mechanism 42's operation into the sowing furrow to cover the sown seeds. It should be understood that the moving mechanism 2 can drive the frame 1 to move as a whole, and the turning mechanism 3 can be used to turn the frame 1 as a whole.

[0022] This embodiment integrates a moving mechanism 2, a steering mechanism 3, a tillage and opening composite mechanism 4, a sowing mechanism 5, and a soil covering mechanism 7 onto the frame 1. This reduces the overall size and turning radius of the intelligent mung bean sowing device, allowing for overall device steering even on small, irregular plots using the steering mechanism 3. Furthermore, in practical operation, the first drive assembly 41 can control the lifting and lowering of the ditching mechanism 42 to enter and leave the soil. The first drive assembly 41 is installed at one end of the frame 1, which can refer to the front end of the frame 1 along the direction of travel during ditching, and is connected to the ditching mechanism. The ditching mechanism 42, which is connected to the first drive assembly 41, is also installed close to the end of the frame 1. During operation, after the ditching mechanism 42 at the front end completes the ditching, the sowing mechanism 5 at the rear can promptly plant the seeds into the ditch. Then, the moving mechanism 2 moves and the covering mechanism 7 backfills the soil to complete the mung bean sowing operation. This solves the technical problems in related technologies where manual mung bean laying is slow and consumes a lot of manpower and resources, while planting mung beans by planting vehicle is difficult to handle due to the large size of the planting vehicle, which limits its turning and passage, and makes storage and maintenance difficult.

[0023] See Figure 2As shown, in some optional embodiments, the tillage and opening composite mechanism 4 further includes a soil turning mechanism 43. The soil turning mechanism 43 may include: a soil turning wheel 431, the soil turning wheel 431 having soil turning arc teeth 4311 around its outer periphery; a support frame 432, the support frame 432 being mounted on the frame 1, the soil turning wheel 431 being mounted on the side of the support frame 432 away from the frame 1; and a first drive mechanism 433, the first drive mechanism 433 being mounted on the frame 1, the output shaft of the first drive mechanism 433 being connected to the side of the support frame 432 near the frame 1. The first drive mechanism 433 is used to drive the support frame 432 to move the soil turning wheel 431 up and down to adapt to different tillage depths. That is, the output shaft of the first drive mechanism 433 and the soil turning wheel 431 are respectively mounted on opposite sides of the support frame 432, with the soil turning wheel 431 mounted on the side of the support frame 432 away from the frame 1. Thus, the height of the soil turning wheel 431 in the vertical direction can be adjusted by the first drive mechanism 433. During operation, the first drive mechanism 433 is first driven to adjust the height of the turning wheel 431 to a suitable position. Then, the moving mechanism 2 is driven to move the entire device. During the movement, the turning arc teeth 4311 on the turning wheel 431 can evenly turn over the surface soil, significantly improving soil looseness and facilitating subsequent ditching by the ditching mechanism 42. In this embodiment, the first drive mechanism 433 can be signal-connected to a controller. The controller sends control signals to the first drive mechanism 433, driving the support frame 432 to adjust the turning wheel 431 vertically to an operating height that matches the current soil quality and agronomic requirements of the plot. Preferably, the first drive mechanism 433 is a drive motor.

[0024] In some optional embodiments, the support frame 432 may include two support plates 4321, a fixed crossbar 4322, and a first rotating rod 4323. The two support plates 4321 are spaced apart along a direction perpendicular to the traveling direction of the frame 1. The two ends of the fixed crossbar 4322 are respectively fixed to the two support plates 4321. The output shaft of the first drive mechanism 433 is rotatably connected to the fixed crossbar 4322. The two ends of the first rotating rod 4323 are respectively rotatably connected to the two support plates 4321, and the turning wheel 431 is fixed to the first rotating rod 4323. The first rotating rod 4323 is connected to a second drive assembly 434. In this embodiment, the turning wheel 431 is fixedly connected to the first rotating rod 4323, achieving synchronous rotation with the first rotating rod 4323. This allows the turning wheel 431 to simultaneously and efficiently break up the soil using the turning arc teeth 4311, enhancing the looseness of the soil after turning. The support frame 432 uses two support plates 4321 and a fixed crossbar 4322 to form a rigid frame structure, providing reliable support for the first rotating rod 4323 and providing a certain axial positioning, effectively dispersing the alternating load and impact vibration generated during turning and cutting. The second drive component 434 can be used to adjust the rotational speed of the first rotating rod 4323, allowing for flexible adjustment based on soil conditions and agronomic requirements. In this embodiment, by setting a rotatable turning wheel 431, the turning arc teeth 4311 are ensured to penetrate the soil evenly and dissipate the soil continuously, providing a flat and finely broken soil base for the subsequent ditching mechanism 42, further ensuring sowing quality and overall machine efficiency.

[0025] See Figure 4As shown, in some optional embodiments, the two support plates 4321 are further connected to a second rotating rod 44, the second rotating rod 44 being parallel to the first rotating rod 4323, and the second rotating rod 44 being disposed on the side of the first rotating rod 4323 biased towards the fixed crossbar 4322. The second drive assembly 434 includes: a second drive mechanism 4341, the output shaft of the second drive mechanism 4341 being fixed to the second rotating rod 44; and a transmission wheel set, the transmission wheel set including a first sprocket 4342 fixed to the second rotating rod 44 and a second sprocket 4343 fixed to the first rotating rod 4323, the first sprocket 4342 and the second sprocket 4343 being connected by a transmission chain 4344. Preferably, each support plate 4321 may include a connecting section and a bent section connected to the connecting section to enhance the overall bending and torsional stiffness of the support plate 4321. The connecting section of the support plate 4321 may be located on the side of the support plate 4321 closer to the frame 1, and its length is shorter than that of the bent section. A connecting plate may be fixed on the frame 1, and the connecting section is connected to the frame 1 by hinge with the connecting plate. The second rotating rod 44 may be located at the connection between the connecting section and the bent section, and a portion of the second rotating rod 44 extends into the connecting plate. In this embodiment, the second drive mechanism 4341 can also be a drive motor, and the second drive mechanism 4341 is also signal-connected to the controller. During operation, the power of the second drive mechanism 4341 is transmitted to the second rotating rod 44, and the power is smoothly transmitted to the first rotating rod 4323 through the first sprocket 4342, the transmission chain 4344 and the second sprocket 4343 to drive the soil turning wheel 431 to rotate. This chain drive layout can effectively buffer the alternating impact load generated when the soil turning arc tooth 4311 cuts into hard soil or encounters rocks. Compared with installing the drive motor at the first rotating rod 4323, this method can transfer the weight of the drive motor to an area closer to the frame 1 body, effectively reducing the weight of the cantilever end of the soil turning mechanism 43, thereby reducing the load on the support plate 4321 and the first rotating rod 4323, and avoiding flexural deformation and vibration caused by long-distance cantilever transmission.

[0026] Preferably, the second drive assembly 434 may further include two first gears and a second gear meshing with the first gears. The first and second gears are arranged vertically, with the first gear fixed to the output shaft of the second drive mechanism 4341 and the second gear fixed to the second rotating rod 44. The power transmission path then becomes: the second drive mechanism 4341 drives the first gear to rotate, the first gear drives the second gear to rotate, and simultaneously, the second rotating rod 44 follows the first gear. Power is then smoothly transmitted to the first rotating rod 4323 via the first sprocket 4342, the transmission chain 4344, and the second sprocket 4343. The second gear can be mounted on a connecting plate. Above the connecting plate, the frame 1 can be fixed with a fixing plate. The second drive mechanism 4341 and the first gear are both mounted on the fixing plate. This arrangement fully utilizes the lateral and longitudinal redundant space of the frame 1, transforming the original transversely unfolded transmission link into a three-dimensional integrated arrangement. This significantly reduces the size of the device in the direction of travel and in the lateral direction, simplifying the overall assembly process and providing convenient operating space for chain tension adjustment and daily maintenance.

[0027] See Figure 5 As shown, in some optional embodiments, the furrowing mechanism 42 may include two furrowing members 421, which are spaced apart along a direction perpendicular to the travel direction of the frame 1, and connected by a stabilizing component 422. The stabilizing component 422 includes a first rod 4221 and a second rod 4222, both of which are parallel to the second rotating rod 44. The first rod 4221 and the second rod 4222 are connected through the furrowing members 421, with both ends of the first rod 4221 rotatably connected to the two furrowing members 421, and both ends of the second rod 4222 fixed to the two furrowing members 421. The second rod 4222 is rotatably sleeved on the outer periphery of the second rotating rod 44, and the first rod 4221 is rotatably connected to the output shaft of the first drive component 41. By setting two spaced-apart furrowing members 421, two sowing furrows can be opened at once during operation, enhancing furrowing efficiency. In this embodiment, the second rod 4222 can serve as a lateral limiting beam to effectively lock the relative distance between the two grooved members 421, while the first rod 4221 serves as a synchronous lifting link to uniformly transmit the output torque of the first drive assembly 41 to the grooved members 421. Preferably, the first drive assembly 41 may include two drive motors, with the output shafts of the two drive motors rotatably connected to the opposite ends of the first rod 4221, so that the first rod 4221 experiences uniform force and a stable movement trajectory during lifting.

[0028] In some optional embodiments, each trenching component 421 includes a first segment 4211, a second segment 4212, and a third segment 4213. The first segment 4211 is sandwiched between the first rod 4221 and the second rod 4222. The second segment 4212 is fixed to the end of the first segment 4211 near the second rod 4222, and the second segment 4212 and the first segment 4211 form an angle with each other. The third segment 4213 is fixed to the end of the second segment 4212 away from the first segment 4211, and a soil-breaking blade is fixed to the end of the third segment 4213 away from the second segment 4212. That is, the first rod 4221 and the second rod 4222 are both connected to the first segment 4211, so that the first segment 4211 of the two trenching components 421, the first rod 4221, and the second rod 4222 form a stable quadrilateral frame, enhancing the force transmission stability. In this embodiment, by setting the trenching component 421 into a three-section structure, the third section 4213 can be bent at a reasonable angle to allow the cutting edge to cut into the soil more easily, reducing resistance. Preferably, the third section 4213 is parallel to the first section 4211, that is, the direction of the third section 4213 and the first section 4211 is consistent.

[0029] See Figure 3 As shown, in some optional embodiments, the seed box 51 includes a seed distribution chamber 511 and at least two seed dropping chambers 512. The seed distribution chambers 511 and the seed dropping chambers 512 are arranged at intervals along a direction perpendicular to the traveling direction of the frame 1. At least two seed dropping chambers 512 are located on opposite sides of the seed distribution chamber 511, and the bottom surface of each seed dropping chamber 512 is connected to the sowing tube 52. A seed distribution disc 513 is installed in the seed distribution chamber 511. The seed distribution disc 513 is designed with a central protrusion structure, and the center height of the seed distribution disc 513 is higher than the outer edge height. In this embodiment, two seed-dropping chambers 512 are provided, located on opposite sides of the seed-separating chambers 511. Before sowing, the worker pours the seeds into the seed box 51. Seeds entering the seed-dropping chambers 512 can be scattered into the sowing furrow through the sowing tube 52. Seeds poured into the seed-separating chambers 511 can also be smoothly separated into the two seed-separating chambers 511 under the action of the seed-separating disc 513. Through the cooperation of the seed-separating chambers 511 and the seed-separating disc 513, not only is the distance between the two adjacent seed-separating chambers 511 increased, allowing the seeds in the two seed-separating chambers 511 to smoothly enter the sowing furrow, but the accuracy of the worker pouring the seeds is also reduced. That is, even if the worker's position is slightly off when pouring the seeds and they are not accurately introduced into the seed-separating chambers 511, the seeds can be automatically returned to their positions by the guide of the inclined surface of the seed-separating disc 513. Preferably, the outer edge of the seeding disc 513 is provided with multiple ridges, each ridge extending radially along the seeding disc 513, and these ridges form a clear flow path on the disc surface.

[0030] In some optional embodiments, each seed-dropping cavity 512 has an opening 5121 on its bottom surface, and the seed-dropping cavity 512 communicates with the sowing tube 52 through the opening 5121; the sowing mechanism 5 further includes a sowing adjustment assembly, which includes a third drive assembly 531 and a drive gear disk 54 connected to the third drive assembly 531, the drive gear disk 54 being fixed to the seed-distributing disk 513; the sowing adjustment assembly also includes at least two seed-dropping wheels 532, each seed-dropping... Each seed drop wheel 532 is rotatably installed in the seed cavity 512. The seed drop wheel 532 near the drive toothed disc 54 meshes with the drive toothed disc 54. Each seed drop wheel 532 has multiple seed drop holes 5321. The third drive assembly 531 is used to drive the drive toothed disc 54 to rotate, so as to drive each seed drop wheel 532 to rotate around its own axis, so that the seed drop holes 5321 are aligned with the openings 5121 in sequence, so as to control the quantitative drop of seeds into the seeding tube 52. In other words, by opening multiple seed dropping holes 5321 on the seed dropping wheel 532, only one seed dropping hole 5321 can be aligned with the opening 5121 each time the seed dropping wheel 532 is driven to rotate by the toothed disc 54. Only after the seed dropping hole 5321 is aligned with the opening 5121 will the seed fall. At this time, the seed sowing density is adjusted by controlling the rotation speed of the seed dropping wheel 532. The periodic alignment of the seed dropping hole 5321 with the opening 5121 is equivalent to setting a "quantitative valve" for the seeds, which effectively prevents the seeds from accumulating and blocking or missing the rows, and ensures that the amount of seeds sown in each row is uniform and the plant spacing is accurately controlled, thereby improving the stability of the sowing operation and the uniformity of seedling emergence in the later stage. In this embodiment, two seed-dropping wheels 532 are provided, located on opposite sides of the drive gear disk 54 and meshing with it respectively. In some other embodiments, when the number of seed-dropping wheels 532 is four or more, the seed-dropping wheels 532 not adjacent to the drive gear disk 54 are sequentially meshed and connected. Optionally, the seed box 51 may include a base plate and a box body connected to the base plate. The opening 5121 on the bottom surface of the seed-dropping cavity 512 may be formed on the base plate, while the seed-dropping cavity 512 and the seed-separating cavity 511 are both formed in the box body.

[0031] See Figure 6As shown, in some optional embodiments, the third drive assembly 531 may include: a third drive mechanism 5311, the output shaft of which is connected to a first bevel gear 5312; and a second bevel gear 5313, which meshes with the first bevel gear 5312 and is coaxially fixed with the drive gear disk 54. In this embodiment, the third drive mechanism 5311 may also be a drive motor, and it is also connected to the controller signal. To save vertical installation space, the third drive mechanism 5311 and the seed box 51 can be arranged side by side in the horizontal direction, that is, the third drive mechanism 5311 is located on the side of the seed box 51. In this case, the output shaft of the third drive mechanism 5311 extends along the traveling direction of the frame 1, and the force of the third drive mechanism 5311 is transmitted to the drive gear disk 54 through the cooperation of the first bevel gear 5312 and the second bevel gear 5313.

[0032] In some optional embodiments, the moving mechanism 2 includes a front wheel assembly 21 and a rear wheel assembly 22. The steering mechanism 3 is connected to the front wheel assembly 21. The front wheel assembly 21 includes two front wheels 211. The steering mechanism 3 includes a connecting frame 31, which includes two horizontal bars 311 and two vertical bars 312. The two horizontal bars 311 are parallel to each other, and both horizontal bars 311 extend along a direction perpendicular to the traveling direction of the frame 1. The two ends of the two vertical bars 312 are respectively connected to the two horizontal bars 311. The ends of the rods are hinged to form a parallelogram linkage structure. The two front wheels 211 are respectively connected to the two vertical rods 312. A servo motor 32 is fixed to the frame 1. The output shaft of the servo motor 32 is fixed with a transmission component 33. The two ends of the transmission component 33 are respectively fixed to the two horizontal rods 311. The servo motor 32 is used to drive the transmission component 33 to rotate, thereby causing the two horizontal rods 311 to generate relative displacement, so that the two vertical rods 312 deflect synchronously, realizing the steering control of the front wheels 211. In this embodiment, the servo motor 32 drives the transmission component 33 to rotate, thereby driving the two horizontal rods 311 to move. Since the horizontal rods 311 are hinged to the vertical rods 312, the vertical rods 312 will deflect synchronously, thereby driving the two front wheels 211 to achieve equiangular steering in the same direction.

[0033] In some optional embodiments, the soil covering mechanism 7 includes two fourth drive mechanisms 71, which are signal-connected to the controller. Each fourth drive mechanism 71 is also a drive motor, and both drive motors are connected to the frame 1, with their output shafts connected to the same support rod 72. The soil covering mechanism 7 also includes two soil covering components 73, which are connected to the frame 1 via a third rotating rod 74. The third rotating rod 74 is rotatably connected to the frame 1 and extends perpendicular to the traveling direction of the frame 1, parallel to the support rod 72, and arranged vertically. Both soil covering components 73 are also connected to the support rod 72, forming a lever linkage system with the third rotating rod 74 as the rotation fulcrum. During operation, the two drive motors synchronously output power to drive the support rod 72 to push, pull, or lift, causing the soil covering components 73 to smoothly deflect around the third rotating rod 74, thereby flexibly adjusting the soil covering plate's entry angle and downward pressure. Preferably, each covering component 73 has two bifurcated rods 731 at an angle to each other in the horizontal direction at the end away from the support rod 72. Each bifurcated rod 731 is connected to a covering plate 732 at the end away from the support rod 72. The two covering plates 732 are arranged at an outward angle. When covering the soil, the loose soil on both sides of the sowing trough can be smoothly pushed towards the center at the same time. This not only effectively expands the single covering area and avoids uneven thickness or seed exposure caused by unilateral operation, but also guides the soil to slide smoothly into the furrow by utilizing the natural confluence channel formed by the angle, which greatly reduces the risk of travel resistance and soil splashing and jamming.
