Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of ridge type and ridge-making related equipment, specifically, to a ridge type that facilitates rice transplanting and an integrated machine for ridge making, mulching and shaping. Background Technology

[0002] Sweet potato is a perennial herbaceous vine containing latex; its tuberous roots are white, red, or yellow; it has adventitious roots growing from its stems; it is also commonly called sweet potato. When propagating and cultivating sweet potatoes, seedlings are usually planted by cutting. A certain length of leafy stem is cut from a healthy seedling and then inserted into the soil. Sweet potatoes are usually propagated asexually, and there are various cultivation methods, such as oblique planting, vertical planting, and horizontal planting. After planting, irrigation and weeding are carried out until the fruit matures.

[0003] Among various planting methods, horizontal planting yields the best growth results. Before planting, the soil is loosened to increase oxygen content and then formed into ridges. After the ridges are formed, mulch is laid on them. Then, using a planting tool (usually a long pole to facilitate inserting the seedling roots into the ridge), the collected seedling stems are inserted through the mulch into the ridge. During this process, the planting hole is located on the side wall, and the soil covering the hole can easily slide down the slope of the ridge, resulting in leaks or incomplete sealing of the planting hole, reducing the effectiveness of the mulch. Under sunlight, the temperature under the mulch rises, and the seedling stems at the planting hole are prone to scorching, causing seedling death and missing seedlings. Therefore, it is necessary to improve and optimize the existing technology to reduce the occurrence of these problems. Summary of the Invention

[0004] To overcome the above-mentioned defects, embodiments of the present invention provide a ridge type that facilitates rice transplanting and an integrated machine for ridge raising, mulching and shaping, which solves the problem of seedling burn under the film when the transplanting holes are leaked or not sealed tightly in related technologies.

[0005] According to one aspect, at least one embodiment of the present invention provides a ridge type that facilitates rice transplanting, comprising: Ridge; Two planting platforms are located on either side of the top surface of the ridge, with the height of the planting platforms lower than the height of the top surface of the ridge.

[0006] For example, in a ridge type that facilitates rice transplanting provided in at least one embodiment of the present invention, the connection between the transplanting platform and the top surface of the ridge is a vertical surface, and an angle A is formed between the vertical surface and the top surface of the ridge, with the angle A being 60°~90°. The vertical surface is used for transplanting rice seedlings.

[0007] According to one aspect, at least one embodiment of the present invention provides an integrated machine for ridging, mulching, and shaping, used for ridging a type of ridge on ridged land that is convenient for rice transplanting, comprising: The frame is capable of moving on the raised beds; Along the direction of movement of the frame, the rotary tillage unit, the ridge shaping component, and the mulching unit are arranged sequentially from front to back; The rotary tillage unit is mounted on the frame and is used for rotary tillage and loosening of the soil in the ridged areas; There are several ridge-shaped shaping components distributed at intervals on the frame. Looking along the direction of frame movement, the ridge-shaped shaping components are located behind the rotary tillage unit. The ridge-shaped shaping components are configured to form a seedling planting platform on the ridge under the drive of the frame. The mulching unit is used to lay mulch film on the surface of the ridges; The upper soil guide plate, located on the frame and above the ridge shaping component, is configured to guide the soil thrown backward by the rotary tillage unit onto the mulch film and pile it on the seedling platform.

[0008] For example, in a ridging, mulching, and shaping integrated machine provided in at least one embodiment of the present invention, a crossbar is provided on the frame behind the rotary tillage unit, and any ridging shaping component includes: Two base plates are spaced apart on the crossbar, with the extension direction of the base plates parallel to the movement direction of the frame. The upper pressure plate is located on the crossbar. The two sides of the upper pressure plate are fixedly connected to two base plates respectively. The upper pressure plate is configured to shape the ridged land after rotary tillage by the frame and the crossbar into the top surface of the ridge. Two side pressure plates are respectively located at the ends of the two base plates away from the crossbar. The side pressure plates are configured to shape the formed ridge under the action of the base plates to form a seedling planting platform for transplanting seedlings. Two ridge-shaped side scrapers are slidably mounted on the frame. The two ridge-shaped side scrapers are located on the left and right sides of the upper pressure plate, respectively. The ridge-shaped side scrapers are configured to be used for scraping and shaping the sides of the ridge after sliding. The sliding direction of the ridge-shaped side scrapers is parallel to the width direction of the frame.

[0009] For example, in a ridging, mulching and shaping integrated machine provided in at least one embodiment of the present invention, the upper pressure plate is set at an angle to the top surface of the ridge, and the side pressure plate is set at an angle to the base plate. Along the moving direction of the frame, from front to back, the distance between the two side pressure plates gradually decreases.

[0010] For example, in a ridging, mulching, and shaping integrated machine provided in at least one embodiment of the present invention, the mulching unit includes: Film-laying rods are located on the left and right sides of the frame, and the film-laying rods have retaining grooves; The film-coating shaft is detachably rotatable in the shaft slot. The film-coating shaft is used to carry the film roll for outputting the mulch film and is located above the upper pressure plate.

[0011] For example, in at least one embodiment of the present invention, a ridging, mulching, and shaping integrated machine further includes a soil covering unit, which includes: The soil-throwing shaft is rotatably mounted on the frame and is located between the rotary tillage unit and the ridge shaping component. Several soil-throwing fan blades are distributed at intervals along the axis of the soil-throwing shaft. The soil-throwing fan blades are configured to throw part of the soil after rotary tillage by the rotary tillage unit onto the mulch film laid on the seedling planting platform under the drive of the soil-throwing shaft.

[0012] For example, in a ridging, mulching, and shaping integrated machine provided in at least one embodiment of the present invention, the soil covering unit further includes: Several sets of side guide soil plates are set on the frame. The side guide soil plates are located between the upper guide soil plate and the upper pressure plate. Each set of side guide soil plates includes two symmetrical and spaced side guide soil plates. Each set of side guide soil plates corresponds to a seedling planting platform. The upper soil guide plate and any set of side soil guide plates are arranged to form a channel through which the soil is thrown out by the soil-throwing fan blades.

[0013] For example, in at least one embodiment of the present invention, a ridge-forming, film-covering, and shaping integrated machine further includes a rolling unit, which comprises: The rolling frame is oscillatingly mounted on the machine frame; The rolling base is rotatably located at the end of the rolling frame away from the machine frame; The adjusting rod is threaded onto the rolling base; The soil pressing roller, which is rotatably mounted on the adjusting rod, is used to roll and press the soil that has been thrown onto the planting platform.

[0014] For example, in a ridging, mulching, and shaping integrated machine provided in at least one embodiment of the present invention, the rolling unit further includes: The sliding component is slidably mounted on the rolling frame and is rotatably connected to the rolling seat. The slide block is slidably mounted on the rolling frame; The elastic element has one end acting on the sliding element and the other end acting on the sliding block. The elastic element is configured to push the sliding element downward so that the sliding element drives the rolling block, adjusting rod and pressing roller to slide downward together.

[0015] The beneficial effects of the embodiments of the present invention are as follows: In this invention, two planting platforms are located on either side of the top surface of the ridge and are lower than the top surface, forming a dedicated planting area. Compared with the prior art of planting on the side of the ridge, the upper surface of the planting platform is a relatively gentle bearing surface, allowing the soil covering the planting hole to remain stably on the platform, reducing the phenomenon of slippage along the slope of the ridge, thus solving the problem of incomplete or inadequate sealing of the planting hole. After the planting hole is effectively sealed, the covering effect of the mulch film is guaranteed, and the space under the film forms a relatively closed environment, preventing the high-temperature air inside the film from directly acting on the seedling stem through the planting hole under sunlight, reducing the phenomenon of seedling burn caused by local high temperature, and lowering the probability of seedling death and missing seedlings. At the same time, the setting of the planting platform provides a clear operating position for seedling planting, facilitating the positioning and use of planting tools, and improving the consistency and efficiency of planting operations.

[0016] The combination of the frame and external power source enables mobile operation of the equipment, allowing for continuous rotary tillage, ridge shaping, and mulching processes. Compared to traditional step-by-step operation modes, this significantly improves the efficiency of ridge preparation. The rotary tillage unit loosens the soil, providing a good foundation for subsequent ridge shaping and ensuring that the ridge shaping components can smoothly form the required ridge and transplanting platform structures. The ridge shaping components ensure the consistency and standardization of transplanting platform formation, avoiding the problem of irregular shapes that occur when manually ridging, and providing a uniform benchmark for subsequent transplanting operations. The mulching unit follows closely behind the ridge shaping components, allowing for immediate mulching after ridge formation. This reduces soil exposure time, prevents soil deformation due to external forces, and ensures a tight fit between the mulch film and the ridge surface, enhancing the mulching effect. Each unit is arranged sequentially along the machine's movement direction, forming a continuous work process. This allows for the coordinated completion of ridge formation, seedling platform shaping, and mulching, ensuring the stable realization of the ridge structure with the seedling platform from an equipment perspective. Simultaneously, in conjunction with the rotary tillage unit's operation, a portion of the soil thrown backward by the rotary tillage unit is guided and transported to the mulch film at the seedling platform using an upper guide plate. This results in soil accumulation on the seedling platform, facilitating rapid sealing of the seedling holes after transplanting, ultimately ensuring the resolution of the seedling hole sealing problem. The design of several ridge-forming components allows the integrated machine to simultaneously form multiple ridges, improving overall work efficiency. Attached Figure Description

[0023] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0024] like Figures 1-2As shown, this illustration depicts a ridge type for easy rice transplanting according to an embodiment of the present invention. The ridge type includes a ridge body 10 and two transplanting platforms 11. The ridge body 10 is a raised structure formed on the ridge surface, having a top surface extending along its length and side surfaces connected to both sides of the top surface. The two transplanting platforms 11 are respectively formed at the two side edges of the top surface of the ridge body 10, and are integral with the ridge body 10. There is a height difference between the upper surface of the transplanting platform 11 and the top surface of the ridge body 10, with the upper surface of the transplanting platform 11 being lower than the top surface of the ridge body 10. The upper surface of the transplanting platform 11 extends along the length of the ridge body 10 and is connected to the side surfaces of the ridge body 10.

[0025] In the horizontal planting of sweet potato seedlings, after the ridge 10 is formed according to the above structure, a plastic film is laid on the top surface of the ridge 10 and the upper surface of the planting platform 11, covering the connection between the top surface of the ridge 10 and the planting platform 11. Finally, soil is covered on the plastic film for pressing; a portion of the soil loosened by rotary tillage unit 30 is piled on top of the plastic film at the planting platform 11. During transplanting, the roots of the seedlings penetrate the plastic film and insert into the soil of the planting platform 11. After transplanting, as the transplanting tools are removed, the soil piled on the plastic film at the planting platform 11 covers the area around the planting hole, sealing it.

[0026] Two planting platforms 11 are located on either side of the top surface of the ridge 10 and are lower than the top surface, forming a dedicated planting area. Compared with the existing technology of planting seedlings on the side of the ridge 10, the upper surface of the planting platform 11 is a relatively gentle bearing surface, which allows the soil covering the planting hole around the planting hole to remain stably on the planting platform 11, reducing the phenomenon of slippage along the slope of the ridge 10, thus solving the problem of incomplete or inadequate sealing of the planting hole. After the planting hole is effectively sealed, the covering effect of the mulch film is guaranteed, and the space under the film forms a relatively closed environment, preventing the high-temperature air inside the film from directly acting on the seedling stem through the planting hole under sunlight, reducing the phenomenon of seedling burn caused by local high temperature, and lowering the probability of seedling death and missing seedlings. At the same time, the setting of the planting platform 11 provides a clear operating position for seedling planting, which facilitates the positioning and use of planting tools and helps to improve the consistency and efficiency of planting operations.

[0027] In some examples, the ridge structure is refined, for example, as Figures 1-2 As shown, in the ridge type that facilitates rice transplanting, a vertical surface 12 is formed at the connection between the transplanting platform 11 and the top surface of the ridge body 10. One side of the vertical surface 12 is connected to the edge of the top surface of the ridge body 10, and the other side is connected to the upper surface of the transplanting platform 11. An angle A is formed between the vertical surface 12 and the top surface of the ridge body 10, with the angle A ranging from 60° to 90°. The side of the transplanting platform 11 away from the vertical surface 12 of the ridge body 10 is connected to the side of the ridge body 10.

[0028] During the sweet potato seedling transplanting process, plastic film is used to cover the top surface of the ridge 10, the vertical surface 12, and the upper and side surfaces of the transplanting platform 11. When the roots of the seedling penetrate the plastic film and are inserted into the soil of the transplanting platform 11, the transplanting hole is located in the area of ​​the vertical surface 12 of the transplanting platform 11.

[0029] The vertical surface 12 forms a 60°~90° angle with the top surface of the ridge 10, providing lateral support to the soil at the planting platform 11. This allows the soil to accumulate better at the planting platform 11. Simultaneously, the angled vertical surface 12 facilitates the subsequent horizontal planting of seedlings, making it easier for workers to plant the seedlings. After planting, the soil accumulated on the planting platform 11 is more likely to seal the planting opening. The vertical surface 12 also clearly defines the boundary between the planting platform 11 and the top surface of the ridge 10, making the positioning during planting more precise and ensuring the consistency of seedling planting positions.

[0030] like Figures 1-7 As shown, this invention illustrates an integrated ridging, mulching, and shaping machine according to one embodiment. The frame 20 of the integrated ridging, mulching, and shaping machine is connected to an external power source via a connector and moves along a preset path on the ridged ground with the power source. Along the moving direction of the frame 20, a rotary tillage unit 30, a ridging shaping component 40, and a mulching unit 50 are arranged sequentially from front to back. The rotary tillage unit 30 is installed at the lower front end of the frame 20, and its rotary tillage components contact the surface of the ridged ground, cutting and loosening the soil during the movement of the frame 20. The ridging shaping component 40 is installed on the frame 20, located behind the rotary tillage unit 30 along the moving direction of the frame 20. Its shaping surface contacts the rotary-tilled soil and moves forward with the frame 20, compressing and shaping the loosened soil into a ridging structure 10 with two seedling trays 11. The mulching unit 50 is mounted on the frame 20, located behind the ridge-shaping component 40 along the moving direction of the frame 20. Its film roll support structure supports the mulch film roll. After the mulch film is drawn out from the film roll, it covers the surface of the ridge 10 after being shaped by the ridge-shaping component 40. The mulching operation is completed as the frame 20 moves. The upper soil guide plate 61 is located above the ridge-shaping component 40 and is used to guide and transport the soil tilled and thrown backward by the rotary tillage unit 30 to the mulch film and pile it at the seedling planting platform 11. The rotary tillage unit 30 uses a rotary tillage shaft and rotary tillage blades set on the rotary tillage shaft in combination to complete the rotary tillage and loosening of the soil.

[0031] A drip irrigation through-hole 22 is provided on the upper surface of the frame 20. A drip irrigation frame 81 is mounted above the drip irrigation through-hole 22. A drip irrigation wheel seat 82 is rotatably mounted on the drip irrigation frame 81. The drip irrigation wheel seat 82 is used to store and release the drip irrigation tape. A drip irrigation guide 83 is provided on the frame 20, located between the rotary tillage unit 30 and the ridge shaping component 40. During operation, the drip irrigation tape is wound on the drip irrigation wheel seat 82. The starting end of the drip irrigation tape passes through the drip irrigation through-hole 22 from top to bottom, and then through the drip irrigation guide 83, leading to the area below the ridge shaping component 40. This allows the drip irrigation tape to be pre-embedded in the ridge body 10 during ridging, facilitating subsequent drip irrigation operations.

[0032] During operation, the external power source drives the frame 20 to move, and the rotary tillage unit 30 first tills and loosens the soil on the raised beds. As the frame 20 continues to move, the ridge shaping component 40 follows, compressing and shaping the tilled soil to form a ridge 10 with two planting platforms 11. Subsequently, the mulching unit 50 continuously lays mulch film on the surface of the formed ridge 10, completing the continuous operation of ridging, shaping, and mulching. The soil thrown out by the rotary tillage unit 30 after tilling is covered on the mulch film with the help of the upper soil guide plate 61, so that soil accumulates on top of the mulch film at the planting platforms 11. The upper soil guide plate 61 guides the falling position of the soil, so that the falling soil presses down on the mulch film and lands exactly on the newly formed planting platforms 11, ensuring that the mulch film adheres tightly to the shape and orientation of the upper surface of the planting platforms 11, and preventing the formation of a gap between the mulch film and the upper surface of the planting platforms 11.

[0033] The combination of the frame 20 and the external power source enables mobile operation of the equipment, allowing for continuous rotary tillage, ridge shaping, and mulching processes. Compared to the traditional step-by-step operation mode, this significantly improves the efficiency of ridge preparation. The rotary tillage unit 30's soil loosening provides a good foundation for subsequent ridge shaping, ensuring that the ridge shaping component 40 can smoothly mold the required ridge body 10 and transplanting platform 11 structure. The ridge shaping component 40 ensures the consistency and standardization of the transplanting platform 11 formation, avoiding the problem of irregular shape of the transplanting platform 11 during manual ridge making, and providing a unified benchmark for subsequent transplanting operations. The mulching unit 50 is set immediately after the ridge shaping component 40, allowing for mulching immediately after the ridge body 10 is formed, reducing soil exposure time, preventing soil deformation due to external forces, and ensuring a tight fit between the mulch film and the surface of the ridge body 10, enhancing the mulching effect. Each unit is sequentially arranged along the moving direction of the frame 20, forming a continuous work process. This allows the formation of the ridge 10, the shaping of the transplanting platform 11, and the mulching operation to be completed in a coordinated manner. From an equipment perspective, this ensures the stable realization of the ridge structure with the transplanting platform 11. Simultaneously, in conjunction with the operation of the rotary tillage unit 30, a portion of the soil thrown backward by the rotary tillage unit 30 is guided and transported to the mulch film at the transplanting platform 11 by the upper soil guide plate 61. This results in soil accumulation on the transplanting platform 11, facilitating the rapid sealing of the transplanting holes after seedling transplanting, ultimately ensuring the solution to the problem of sealing the transplanting holes. The design of several ridge shaping components 40 allows the integrated machine to simultaneously form multiple ridges 10, improving overall work efficiency.

[0034] In some examples, the all-in-one machine structure is optimized, for example, such as Figure 3 and Figures 6-12 As shown, in the integrated ridging, mulching, and shaping machine, the crossbar 21 is horizontally fixed to the frame 20 and located on the rear side of the rotary tillage unit 30 along the moving direction of the frame 20. Several ridging shaping components 40 share one crossbar 21; two base plates 41 in the ridging shaping component 40 are installed at intervals on the lower surface of the crossbar 21, and the length direction of the base plates 41 is consistent with the moving direction of the frame 20, and they are symmetrically distributed along the length direction of the crossbar 21. The upper pressure plate 42 is fixed to the rear side of the crossbar 21 and located between the two base plates 41. The two sides of the upper pressure plate 42 are respectively connected to the upper edge of the inner sidewall of the two base plates 41, and the lower surface of the upper pressure plate 42 is a forming surface adapted to the top surface of the ridging body 10. Two side pressure plates 43 are respectively fixed to the ends of the two base plates 41 away from the crossbar 21, and the side pressure plates 43 extend away from the base plates 41, and their lower surfaces are forming surfaces adapted to the seedling insertion platform 11. Two ridge-shaped side scrapers 44 are slidably set on the left and right sides of the upper pressure plate 42 respectively. The ridge-shaped side scrapers 44 are used to scrape and shape the sides of the ridge body 10. After the ridge-shaped side scrapers 44 slide, the overall width of the ridge body 10 can be adjusted to meet the planting requirements of different varieties of seedlings.

[0035] When the frame 20 moves under the drive of the power source, the crossbar 21 moves synchronously with the frame 20, causing the base plate 41, the upper pressure plate 42, and the side pressure plates 43 to act on the soil after rotary tillage. The lower surface of the upper pressure plate 42 contacts the soil, compressing the soil to form the top surface of the ridge 10; at the same time, the lower surfaces of the two side pressure plates 43 contact the soil on both sides of the top surface of the ridge 10, respectively, and through compression, shape the planting platforms 11 located on both sides of the top surface of the ridge 10. The base plate 41 provides lateral constraint to the soil as it moves with the crossbar 21.

[0036] The crossbar 21 serves as a connecting base, integrating the base plate 41, upper pressure plate 42, and side pressure plate 43 into a single structure. This ensures that all components move synchronously when the frame 20 moves, guaranteeing the stability of the ridge shaping. The spacing between the two base plates 41 provides installation support for the upper pressure plate 42 and simultaneously forms lateral obstruction during soil shaping, preventing excessive soil diffusion to both sides and ensuring the shaping effect of the ridge 10. The fixed connection between the upper pressure plate 42 and the base plate 41 allows the shaping process of the top surface of the ridge 10 and the two side planting platforms 11 to proceed synchronously, ensuring the accuracy of the positional relationship between the top surface of the ridge 10 and the planting platforms 11 and avoiding height deviations. The connection structure between the side pressure plate 43 and the base plate 41 allows the shaping of the planting platforms 11 and the shaping of the ridge 10 to proceed in tandem, ensuring that the planting platforms 11 and the ridge 10 form a single structure. This enhances the structural stability of the planting platforms 11 and prevents soil collapse of the planting platforms 11 during subsequent transplanting. This integrated, fixed structure allows for the shaping of the top surface of the ridge 10 and the seedling platform 11 with a single movement, simplifying the operation process, ensuring the consistency of the ridge structure, and providing a reliable foundation for subsequent mulching and transplanting operations. The width of the ridge 10 can be adjusted by sliding the ridge-side scraper 44, making it suitable for planting different varieties of seedlings and expanding the applicability of the integrated machine.

[0037] In some examples, the all-in-one machine structure is optimized, for example, such as Figure 3 and Figures 6-12 As shown, in the ridge-forming component 40 of the integrated ridge-forming and mulching machine, the forming surface of the upper pressure plate 42 is set at an angle to the horizontal plane, with the side closer to the front end of the frame 20 in the moving direction higher than the side closer to the rear end. The side pressure plate 43 is connected to the end of the base plate 41 away from the crossbar 21, and the extending direction of the side pressure plate 43 is set at an angle to the extending direction of the base plate 41, with the side pressure plate 43 inclined towards the other base plate 41. The two side pressure plates 43 are symmetrically distributed around the central axis of the upper pressure plate 42, and the distance between them gradually decreases from the end connected to the base plate 41 to the end away from the base plate 41.

[0038] When the frame 20 moves the ridge-forming component 40, the inclined forming surface of the upper pressure plate 42 first contacts the rotary-tilled soil. As the frame 20 moves, it gradually compresses the soil backward, increasing the overall density of the ridge 10 and preventing it from becoming too loose. Simultaneously, as the two side pressure plates 43 move with the base plate 41, they exert an inward compressive force on the soil on both sides of the ridge 10 through changes in their tilt angle and spacing, shaping a stepped planting platform 11 that corresponds to the top surface of the ridge 10. The upper surface of the planting platform 11 tilts accordingly with the tilt angle of the side pressure plates 43, resulting in an angle A between the vertical surface 12 and the top surface of the ridge 10.

[0039] The upper pressure plate 42 is set at an angle to the top surface of the ridge 10, so that the soil is subjected to a component force along the inclined direction during the shaping process, promoting downward compression of the soil, enhancing the compactness of the top surface of the ridge 10, and preventing ridge collapse due to loose soil during subsequent mulching. The angle between the side pressure plate 43 and the base plate 41, as well as the variation in the spacing between the two side pressure plates 43, causes the transplanting platform 11 to be subjected to inward compression during the shaping process, increasing the soil density of the transplanting platform 11, enhancing its load-bearing capacity, and providing a structural basis for the stable sealing of the transplanting holes by the soil during transplanting. The inclined setting and the variation in spacing of the side pressure plates 43 ensure that the connection between the transplanting platform 11 and the top surface of the ridge 10 forms a clear boundary. Together with the inclined angle of the upper pressure plate 42, a natural height difference is formed between the top surface of the ridge 10 and the transplanting platform 11. This meets the structural requirement that the transplanting platform 11 is lower than the top surface of the ridge 10 without additional adjustments, ensuring the accuracy and consistency of ridge shaping. This design of angle and spacing makes the force distribution on the soil more reasonable during the movement of the ridge shaping component 40, which not only ensures the shaping effect of the ridge body 10 and the seedling platform 11, but also reduces the resistance when the equipment moves and improves the work efficiency.

[0040] In some examples, the all-in-one machine structure is optimized, for example, such as Figure 3 and Figures 6-12 As shown, in the mulching unit 50 of the ridge-mulching and shaping integrated machine, mulching rods 51 are fixed on the left and right sides of the frame 20, symmetrically distributed along the width of the frame 20. Each mulching rod 51 has a retaining groove 52 with its opening facing upwards. The two ends of the mulching shaft 53 are respectively embedded in the retaining grooves 52 of the two mulching rods 51, allowing it to rotate around its own axis within the retaining grooves 52. A film roll is sleeved on the mulching shaft 53, and the free end of the film extends downwards after being drawn from the film roll, covering the surface of the ridge 10 after being shaped by the ridge shaping component 40. The initial end of the film is pressed onto the ridge 10 by manually filling soil.

[0041] When the frame 20 moves under the drive of the power source, the soil buried at the end of the mulch film creates a pulling force on the mulch film. Under this pulling force, the mulch film roll rotates around its own axis, gradually releasing the mulch film and laying it onto the formed ridge 10. When the mulch film roll is used up or a different specification of mulch film needs to be replaced, the mulching shaft 53 is pulled out along the opening direction of the shaft retaining groove 52, the old mulch film roll is removed, a new mulch film roll is put on, and then both ends of the mulching shaft 53 are re-embedded into the shaft retaining groove 52.

[0042] The retaining groove 52 of the mulching laying rod 51 provides a detachable mounting structure for the mulching rotating shaft 53, making the replacement of the mulch film roll simple and quick, reducing equipment downtime and improving operational continuity. The rotational engagement between the mulching rotating shaft 53 and the retaining groove 52 ensures smooth release of the mulch film during laying, avoiding tearing or uneven laying caused by jamming. The mulching rotating shaft 53's position above the upper pressure plate 42 allows the mulch film to fall naturally from a higher position to cover the surface of the ridge 10, reducing frictional interference between the mulch film and equipment components and ensuring the flatness of the mulch film laying. The symmetrically distributed mulching laying rods 51 ensure even force distribution on the mulching rotating shaft 53, preventing the film roll from tilting during rotation, ensuring that the mulch film accurately covers the preset position on the ridge 10, adapting to the structure of the ridge 10 and the seedling platform 11 shaped by the ridge shaping component 40, enhancing the mulching effect, and providing a foundation for the effective sealing of the subsequent seedling holes.

[0043] In some examples, the all-in-one machine structure is optimized, for example, such as Figure 3 and Figures 6-12 As shown, in the soil covering unit 60 of the ridge-mulching and shaping integrated machine, the soil-throwing shaft 62 is rotatably mounted on the frame 20 via a bearing seat. Its axial direction is parallel to the width direction of the frame 20 and is located between the rotary tillage unit 30 and the ridge shaping component 40. Several soil-throwing fan blades 63 are fixed at intervals along the axial direction of the soil-throwing shaft 62 to the outer peripheral wall of the soil-throwing shaft 62, and the extension direction of the soil-throwing fan blades 63 is consistent with the radial direction of the soil-throwing shaft 62.

[0044] When the frame 20 moves under the drive of the power source, the soil-throwing shaft 62 rotates around its own axis under the drive of the transmission mechanism (using the conventional combination of chain and sprocket in existing technology), causing the soil-throwing fan blades 63 to rotate synchronously. Some of the soil after being rotary tilled by the rotary tillage unit 30 is contacted and impacted by the soil-throwing fan blades 63, and is thrown towards the rear ridge shaping component 40 under the action of centrifugal force. After the ridge shaping component 40 shapes the seedling platform 11 and the mulching unit 50 lays the mulch film on the surface of the seedling platform 11, the soil thrown by the soil-throwing fan blades 63 falls onto the mulch film of the seedling platform 11 with the guidance and conveying action of the upper soil guide plate 61, forming a covering layer.

[0045] The combination of the soil-throwing shaft 62 and the soil-throwing fan blades 63 enables the directional throwing of some of the rotary-tilled soil onto the plastic film on the transplanting platform 11, achieving automatic soil covering of the plastic film and replacing manual soil covering, thus improving work efficiency. The soil covering on the plastic film on the transplanting platform 11 provides a ready-made soil source for sealing the transplanting holes during subsequent transplanting, reducing the need for additional soil extraction. Furthermore, the soil pre-covered on the plastic film allows for rapid filling of the transplanting holes after transplanting, improving the convenience and tightness of sealing and further reducing the risk of seedling burn. The placement of the soil-throwing shaft 62 between the rotary tillage unit 30 and the ridge-shaping component 40 allows the soil to be directionally transported during ridge shaping, forming a continuous process with ridge shaping and film covering operations, ensuring the synergy between soil covering, ridge formation, and film covering.

[0046] In some examples, the all-in-one machine structure is optimized, for example, such as Figure 3 and Figures 6-12 As shown, in the soil covering unit 60 of the ridge-mulching and shaping integrated machine, the upper soil guide plate 61 is fixed on the frame 20, located above and behind the soil-throwing shaft 62. The upper soil guide plate 61 is generally curved downwards, and a directional guide plate is provided at the end of the upper soil guide plate 61 away from the frame 20 to ensure the final falling position of the soil. Several sets of side soil guide plates 64 are installed on the frame 20, positioned between the upper soil guide plate 61 and the upper pressure plate 42. Each set of side soil guide plates 64 is spaced apart along the width direction of the frame 20. Each set of side soil guide plates 64 includes two side soil guide plates 64. The position of each set of side soil guide plates 64 corresponds to a seedling planting platform 11 on the ridge body 10. The two side soil guide plates 64 are symmetrically arranged with the corresponding seedling planting platform 11 as the center of symmetry, and are spaced apart from each other. The lower surface of the upper soil guide plate 61 and the inner surface of any set of side soil guide plates 64 together form a channel. The entrance end of the channel corresponds to the soil throwing direction of the soil throwing fan blade 63, and the exit end faces the upper part of the corresponding seedling platform 11.

[0047] When the soil-throwing shaft 62 drives the soil-throwing fan blades 63 to rotate, the thrown soil enters the channel formed by the upper soil guide plate 61 and the corresponding set of side soil guide plates 64. Under the constraint and guidance of the channel, the soil moves along the channel towards the outlet end and is finally transported to the top of the planting platform 11 corresponding to the set of side soil guide plates 64, covering the surface of the mulch film laid on the planting platform 11.

[0048] The upper soil guide plate 61 provides upper constraint on the soil ejected by the soil-throwing fan blades 63, preventing soil from splashing upwards and improving soil utilization. The side soil guide plates 64 are grouped, with each group corresponding to a planting platform 11, allowing the soil to be precisely guided to the predetermined covering position. This ensures that each planting platform 11 receives an appropriate amount of soil coverage on the mulch film, avoiding uneven soil distribution. The symmetrically distributed side soil guide plates 64 form channels that directionally transport the soil, reducing diffusion losses during transport and ensuring that the amount of soil reaching the planting platform 11 is sufficient to cover the mulch film and provide ample cover soil for subsequent sealing of the planting holes. The channel enclosed by the upper soil guide plate 61 and the side soil guide plate 64 isolates the soil covering process from other operation links, preventing the soil from interfering with the normal operation of the rotary tillage unit 30 or the ridge shaping component 40. At the same time, it enables the soil to be continuously and stably transported to the target position during the movement of the frame 20. Working in conjunction with the mulching unit 50, it ensures that the mulch film is immediately covered by soil after it is laid, enhancing the fixing effect of the mulch film and laying the foundation for the effective sealing of the seedling holes in the subsequent rice transplanting operation.

[0049] In some examples, the all-in-one machine structure is optimized, for example, such as Figure 3 and Figures 6-12 As shown, in the rolling unit 70 of the ridge-mulching and shaping integrated machine, one end of the rolling frame 71 is connected to the frame 20 via a rotating shaft, and can swing relative to the frame 20 around the rotating shaft. The swinging of the rolling frame 71 allows the rolling unit 70 to have two states: working and retracted. In working mode, the rolling frame 71 swings backward and downward towards the frame 20, positioning it above the upper pressure plate 42. In retracted mode, it swings upward and forward, positioning the rolling frame 71 above the frame 20. The rolling seat 72 is rotatably connected to the end of the rolling frame 71 away from the frame 20 via a pin, and can rotate relative to the rolling frame 71 around the pin. The outer surface of the adjusting rod 73 is threaded, engaging with a threaded hole on the rolling seat 72, with one end of the adjusting rod 73 passing through the threaded hole. The pressing roller 74 is rotatably connected to the end of the adjusting rod 73 via a wheel axle, and can rotate freely around the wheel axle. The outer circumference of the pressing roller 74 is in contact with the soil thrown onto the planting platform 11.

[0050] As the frame 20 moves, the rolling frame 71 moves synchronously with it, and the pressing roller 74 presses against the soil surface of the planting platform 11 under its own weight and the action of the adjusting rod 73. By rotating the adjusting rod 73, the length of the adjusting rod 73 extending out of the rolling seat 72 can be changed, thereby adjusting the contact area between the pressing roller 74 and the soil surface of the planting platform 11. The pressing roller 74 rolls on the soil surface, compacting the soil covering the mulch film, so that the soil adheres tightly to the mulch film and is fixed on the planting platform 11.

[0051] The rotatable connection between the rolling frame 71 and the frame 20 allows the pressing roller 74 to adapt to the undulations of the ridge 10 surface, ensuring that the pressing roller 74 remains in contact with the soil surface during the movement of the frame 20, thus guaranteeing a consistent rolling effect. In actual use, the rotatable connection between the rolling frame 71 and the frame 20 can be locked using a pin hole, a common technique in existing technology, to fix the height of the pressing roller 74. This ensures the consistency of the soil height after compaction on the transplanting platform 11, providing a consistent and stable working foundation for subsequent transplanting operations.

[0052] The threaded connection between the adjusting rod 73 and the rolling seat 72 allows for appropriate adjustment of the contact area between the pressing roller 74 and the soil surface of the transplanting platform 11, thereby preventing localized under-pressing or excessive compression due to angular deviations. The rotational engagement between the rolling seat 72 and the rolling frame 71 allows the length extension direction of the pressing roller 74 to be adaptively adjusted according to the tilt angle of the transplanting platform 11 (this can be locked using a pin hole, a common technique in existing technologies), improving the consistency of soil compaction. The rotational setting of the pressing roller 74 converts sliding friction into rolling friction, reducing disturbance to the soil surface and ensuring that the rolling pressure is evenly applied to the soil surface. This ensures a stable soil cover layer at the transplanting platform 11, providing a solid foundation for effective sealing of the transplanting holes during subsequent transplanting and further enhancing the sealing effect of the mulch film.

[0053] In some examples, the all-in-one machine structure is optimized, for example, such as Figure 3 and Figures 6-12 As shown, in the rolling unit 70 of the ridge-mulching and shaping integrated machine, a first groove is provided on the rolling frame 71, and a sliding member 75 is slidably disposed in the first groove. The sliding member 75 is rotatably connected to the end of the rolling seat 72 away from the compaction roller 74 via a pin. The sliding seat 76 is disposed on the rolling frame 71, and when the integrated machine is operating, the sliding seat 76 is located above the sliding member 75. One end of the elastic member 77 acts on the protrusion of the sliding member 75, and the other end acts on the protrusion of the sliding seat 76. The elastic member 77 is in a compressed state when working, and the elastic member 77 is a spring selected from the prior art.

[0054] When the pressing roller 74 contacts the soil on the surface of the planting platform 11 and receives an upward reaction force, this force is transmitted to the sliding member 75 through the adjusting rod 73 and the rolling seat 72, pushing the sliding member 75 to slide upward along the rolling frame 71 and compressing the elastic member 77. The elastic member 77 generates a reverse elastic force under pressure, which acts on the pressing roller 74 through the sliding member 75, the rolling seat 72, and the adjusting rod 73, keeping the pressing roller 74 pressed against the soil. When a bulge appears on the soil surface, the pressing roller 74 moves upward, causing the sliding member 75 to further compress the elastic member 77; when a depression appears on the soil surface, the elastic member 77 extends, pushing the sliding member 75 downward, causing the pressing roller 74 to move downward to conform to the soil surface.

[0055] The sliding engagement between the sliding element 75 and the rolling frame 71 provides the compaction roller 74 with adjustable vertical movement space. Combined with the elastic force of the elastic element 77, the compaction roller 74 can automatically adjust its position according to the undulations of the soil surface, ensuring effective contact with the soil throughout the movement of the frame 20 and preventing incomplete compaction or missed compaction due to local height differences. The continuous elastic force generated by the elastic element 77 keeps the pressure of the compaction roller 74 on the soil relatively stable, reducing pressure fluctuations caused by mechanical vibration or uneven ground, and ensuring consistent soil compaction results. The sliding block 76 provides a stable support point for the elastic element 77, and can slide along the rolling frame 71, facilitating adjustment of the initial compression of the elastic element 77 according to actual operational needs, thereby adjusting the initial pressure of the compaction roller 74. This elastic buffer structure reduces the impact force when the soil pressing roller 74 collides with hard foreign objects, reduces the wear of equipment parts, and extends service life. At the same time, through continuous and stable rolling action, it ensures that the soil at the planting platform 11 is tightly covered with mulch film, providing a guarantee for the reliable sealing of subsequent planting holes.

[0056] In addition, the rolling base 72 has several circumferentially distributed locking grooves 721, the rolling frame 71 has a sliding pin seat 91, the pin seat 91 has a sliding locking pin 92, and an elastic element 93 is provided between the pin seat 91 and the locking pin 92. One end of the elastic element 93 acts on the pin seat 91, and the other end of the elastic element 93 acts on the locking pin 92. With the elastic force provided by the elastic element 93, the locking pin 92 moves away from the pin seat 91 and slides towards the locking groove 721 until the locking pin 92 is inserted into one of the locking grooves 721.

[0057] During operation, the elastic force provided by the elastic element 93 pushes the locking pin 92 towards the locking groove 721 until the end of the locking pin 92 is inserted into the locking groove 721, thus completing the relative fixed connection between the rolling seat 72 and the sliding element 75. This facilitates the adjustment and fixing of the relative angle between the pressure roller and the seedling platform 11, so that the pressure roller meets the preset requirements after rolling the soil.
