Description

Technical Field

[0001] This invention relates to the field of crop cultivation technology, specifically to a simple mulched and perforated cabbage transplanting device and method. Background Technology

[0002] In the field of cabbage cultivation, traditional seedling transplanting methods face significant technical bottlenecks: cabbage transplanting is mostly concentrated in spring, and seedlings lose moisture quickly after being dug up in low-temperature environments. During manual transplanting, it is necessary to frequently carry out moisture-preserving operations to maintain the moisture of the seedlings, resulting in high labor intensity and low work efficiency, making it difficult to meet the labor cost control requirements of large-scale planting.

[0003] In the prior art, Chinese patent application publication number CN104686037A discloses an integrated machine for transplanting Astragalus seedlings, covering and punching holes. It integrates functional modules such as trenching and planting, fertilization, covering and punching holes through the frame, realizing the mechanization of Astragalus transplanting, which improves transplanting efficiency to a certain extent and reduces manual intervention. However, the technical solution of this equipment is designed for the biological characteristics of Astragalus membranaceus, which is fundamentally different from the planting needs of cabbage. The equipment adopts a process of planting seedlings first and then covering with film and punching holes, which requires precise hole positioning and seedling posture control. Cabbage seedlings are prone to tilting during transplanting due to mismatch between the film holes and the seedling position, which places extremely high demands on the mechanical precision of the equipment. Moreover, there are significant differences between cabbage and Astragalus membranaceus in terms of seedling morphology, such as root diameter, plant height, row and plant spacing, and planting depth. Directly applying this equipment will result in insufficient adaptability of core components such as furrow opening depth control and seedling pressing wheel pressure parameters. At the same time, cabbage planting emphasizes the economy and ease of operation of equipment. The complex fertilization device and multi-section frame structure of existing Astragalus membranaceus transplanting equipment have functional redundancy in the cabbage transplanting scenario, increasing manufacturing costs and maintenance difficulty. Summary of the Invention

[0004] To address the aforementioned issues, a simple mulched and perforated cabbage transplanting device and method are provided. Transplanting is achieved by first mulching and perforating the film, followed by manual seedling placement. This reduces the reliance on precise mechanical positioning and provides a clear benchmark for seedling placement through perforation in the mulch film. Workers only need to place the seedling in the perforated area, effectively avoiding seedling tilting caused by misalignment between the perforation and seedling position during mechanical planting. This method is particularly suitable for cabbage seedlings with short stems and a tendency to lodging, significantly improving the matching accuracy between seedlings and perforations during transplanting.

[0005] To address the problems of existing technologies, this invention provides a simple mulched cabbage transplanting device, comprising a frame and a traction frame mounted on the frame; the frame is sequentially arranged along the working direction with an unwinding mechanism for releasing and laying the mulch film on the ground, a punching mechanism for punching holes in the laid mulch film, and an operating platform for supporting workers to place cabbage seedlings at the punched holes in the mulch film; both sides of the unwinding mechanism are provided with a re-pressing mechanism for applying pressure to the edge of the film, the re-pressing mechanism including rollers that contact the edge of the mulch film and an adjustment component that can adjust the pressure applied by the rollers.

[0006] Preferably, the repressing mechanism further includes a connecting rod hinged to the frame, a roller rotatably disposed on the connecting rod at one end away from the frame, a driving block disposed on the frame, and an elastic element disposed between the driving block and the connecting rod.

[0007] Preferably, the frame is provided with a first slide groove extending in the horizontal direction, the middle part of the connecting rod is provided with a drive rod hinged thereto, the other end of the drive rod is slidably disposed on the first slide groove, and the two ends of the elastic member are respectively sleeved on the drive block and the connection part between the drive rod and the first slide groove.

[0008] Preferably, the adjusting assembly includes a lead screw that is disposed beside the first slide groove and is rotatable, the axis of the lead screw extending along the length direction of the first slide groove, a drive block sleeved on the lead screw and threadedly engaged therewith, and a second slide groove extending in the horizontal direction provided on the frame, the drive block being slidably disposed on the second slide groove.

[0009] Preferably, a support rod parallel to the connecting rod is provided on the side of the connecting rod, and the support rod is hinged to the frame. A support frame is provided between the bottom of the support rod and the connecting rod, and a rotatable guide wheel is provided on the support frame.

[0010] Preferably, the punching mechanism includes a rotatable roller mounted on a frame, with a plurality of punching posts equidistantly arranged around its axis on the roller. The punching posts extend radially along the roller, and the punching heads are all hollow cylindrical structures.

[0011] Preferably, the rotating roller has a hollow structure, with multiple perforated columns communicating with the interior of the rotating roller. The interior of the rotating roller is provided with spiral guide strips, and the two ends of the guide strips are provided with opposite threads. Both ends of the rotating roller are provided with openings.

[0012] Preferably, the operating platform includes two slides, and the two slides are equipped with traction ropes that are connected to the frame.

[0013] Preferably, the bottom of the slide is provided with a plurality of guide blocks arranged along its length, and the slide is provided with a plurality of mounting seats arranged along its length.

[0014] A method for transplanting cabbage, applied to the aforementioned simple mulched and perforated cabbage transplanting device, includes the following steps:

[0015] S1. Connect the transplanting device to the external power equipment via the traction frame and start it to drive the frame to move along the field operation direction.

[0016] S2. The unwinding mechanism moves along the frame to release the mulch film and lay it on the ground.

[0017] S3. The rollers of the re-pressing mechanism contact the edge of the mulch film and adjust the pressure through the adjustment component to compact the edge of the mulch film.

[0018] S4. The punching mechanism punches holes in the fixed mulch film at preset intervals to form transplanting holes.

[0019] S5. Staff members use the operating platform to place cabbage seedlings into the holes of the plastic film after drilling, thus completing the transplanting operation.

[0020] The advantages of this invention compared to the prior art are:

[0021] 1. This invention transplants seedlings by first covering the seedbed with plastic film and then manually placing the seedlings. This reduces the reliance on precise mechanical positioning. The perforation of the plastic film provides a clear benchmark for seedling placement, and workers only need to place the seedlings in the holes. This effectively avoids the problem of seedling tilting caused by the deviation between the hole and the seedling position during mechanical planting. It is especially suitable for the characteristics of cabbage seedlings, which have short stems and are prone to lodging, and significantly improves the matching accuracy between seedlings and holes during transplanting.

[0022] 2. The present invention uses a re-pressing mechanism set on both sides of the unwinding mechanism. Through the cooperation of rollers and adjustment components, the pressure applied to the edge of the mulch film can be dynamically adjusted according to different soil types and terrain conditions. This ensures that the edge of the mulch film is tightly attached to the ground surface, preventing the film from shifting due to factors such as wind force and soil moisture changes. It can also adapt to uneven field surfaces through pressure adjustment, enhance the stability of mulch film laying, and create a good heat-preserving and moisture-retaining environment for the growth of cabbage seedlings.

[0023] 3. This invention provides a stable support structure for the support frame and guide wheel through the parallel hinged connection of the support rod and connecting rod. This allows the guide wheel to adaptively adjust its height according to the undulations of the ground, ensuring that it can roll along the ground surface on fields with varying degrees of flatness. This uniformly guides the soil to the edge of the mulch film, mechanizing the soil covering process. It ensures that the edge of the mulch film is effectively covered by soil, further improving the fixing effect of the mulch film and reducing film displacement caused by wind or soil moisture changes, thus creating a good surface environment for the growth of cabbage seedlings.

[0036] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0037] like Figures 1 to 6 As shown: A simple mulched and perforated cabbage transplanting device includes a frame 1 and a traction frame 11 mounted on the frame 1; the frame 1 is provided with, along the working direction, a roll-up mechanism 12 for releasing the mulch film 2 and laying it on the ground, a perforation mechanism 13 for perforating the laid mulch film 2, and an operating platform 14 for supporting workers to place cabbage seedlings at the perforated holes in the mulch film 2; both sides of the roll-up mechanism 12 are provided with a pressure-reapplying mechanism 15 for applying pressure to the edge of the film, the pressure-reapplying mechanism 15 includes a roller 151 that contacts the edge of the mulch film 2 and an adjustment component 153 that can adjust the pressure applied by the roller 151.

[0038] This device is connected to an external power source (such as a tractor) via a traction frame 11. Under the power drive, the frame 1 moves along the field operation direction. The unwinding mechanism 12 releases the mulch film 2 along with the movement of the frame 1 and lays it on the ground. Subsequently, the two sides of the mulch film 2 are simultaneously pressed by the rollers 151 in the pressing mechanism 15. The pressure applied by the rollers 151 to the edges of the mulch film 2 is adjusted by the adjusting component 153 so that the rollers 151 press the edges of the mulch film 2 with appropriate force, ensuring that the mulch film 2 will not shift when the punching mechanism 13 makes holes in the mulch film 2. Then, the punching mechanism 13 punches holes in the fixed mulch film 2 at preset intervals to form holes for transplanting cabbage seedlings. The operator, on the operating platform 14 located behind the punching mechanism 13, puts the cabbage seedlings into the holes of the mulch film 2 according to the hole positions to complete the transplanting operation.

[0039] Compared to existing technologies, the method of transplanting seedlings by first covering the film and then manually placing the seedlings reduces the reliance on precise mechanical positioning. The perforation of the film provides a clear benchmark for seedling placement, and staff only need to place the seedlings in the holes. This effectively avoids the problem of seedling tilting caused by the deviation between the hole and the seedling position during mechanical planting. It is especially suitable for the characteristics of cabbage seedlings, which have short stems and are prone to lodging, and significantly improves the matching accuracy between seedlings and holes during transplanting.

[0040] The pressure adjustment mechanism 15 set on both sides of the unwinding mechanism 12, through the cooperation of rollers 151 and adjustment components 153, can dynamically adjust the pressure applied to the edge of the mulch film 2 according to different soil and terrain conditions. This ensures that the edge of the mulch film 2 is tightly attached to the ground surface, preventing the film from shifting due to factors such as wind and soil moisture changes. It can also adapt to the unevenness of the field surface through pressure adjustment, enhance the stability of the mulch film 2, and create a good heat preservation and moisture retention environment for the growth of cabbage seedlings.

[0041] The operating platform 14 transforms the complex seedling planting process in mechanical transplanting into a manual-assisted delivery process. Utilizing the flexibility of manual operation, it accommodates the morphological differences and transplanting spacing requirements of various cabbage varieties. This avoids the high costs and maintenance difficulties associated with complex mechanical seedling clamping and delivery mechanisms in traditional fully automated transplanting equipment. While ensuring operational efficiency, it significantly reduces equipment manufacturing costs and lowers the barrier to entry, making the device more suitable for the high-efficiency, low-cost transplanting needs of large-scale cabbage cultivation. It simplifies the cumbersome steps in the traditional transplanting process, improves the continuity and convenience of field operations, and effectively reduces the labor intensity of workers.

[0042] like Figures 4 to 8 As shown: The repressing mechanism 15 also includes a connecting rod 1511 hinged to the frame 1, a roller 151 rotatably disposed on the connecting rod 1511 at one end away from the frame 1, a driving block 152 disposed on the frame 1, and an elastic element 1521 disposed between the driving block 152 and the connecting rod 1511.

[0043] As the frame 1 moves along the working direction, the roller 151 moves synchronously with the frame 1 and contacts the edge of the mulch film 2. Because an elastic element 1521 is provided between the drive block 152 on the frame 1 and the connecting rod 1511, this elastic element 1521 provides elastic support for the connecting rod 1511, allowing the connecting rod 1511 to swing relative to the frame 1 around the hinge point. When the ground is uneven, the roller 151 moves up and down with the change in ground height, causing the connecting rod 1511 to swing. At this time, the elastic element 1521 provides cushioning through compression or stretching. While adjusting the pressure angle of the roller 151 on the mulch film 2, it maintains continuous pressure on the edge of the mulch film 2, ensuring that the edge of the mulch film 2 is tightly adhered to the ground surface.

[0044] The hinged connection between the connecting rod 1511 and the frame 1 allows the roller 151 to flexibly adjust its position according to the undulations of the ground, adapting to fields with varying flatness. This avoids problems such as uneven compaction of the mulch film 2 or the roller 151 being suspended due to uneven ground, enhancing the device's applicability to complex terrain. The elastic element 1521 between the drive block 152 and the connecting rod 1511 provides buffering force. When the roller 151 contacts a raised area of ​​the ground, it reduces the impact through elastic compression; when it contacts a recessed area, it maintains the pressure on the mulch film 2 through elastic stretching. This avoids tearing of the mulch film 2 or insufficient pressure that may be caused by rigid compaction, forming a rigid-flexible edge fixing mechanism for the mulch film 2. Compared to traditional fixed pressure rollers, this structure ensures that the edges of the mulch film 2 are effectively compacted to prevent displacement, and it can also compensate for contact deviations caused by uneven ground through elastic adaptive compensation, improving the stability and reliability of the mulch film 2 laying and creating favorable environmental conditions for the growth of cabbage seedlings.

[0045] like Figures 4 to 8As shown: A first slide groove 1513 extending horizontally is provided on the frame 1. A drive rod 1512 is provided in the middle of the connecting rod 1511 and is hinged thereto. The other end of the drive rod 1512 is slidably provided on the first slide groove 1513. The two ends of the elastic member 1521 are respectively sleeved on the drive block 152 and the connection part between the drive rod 1512 and the first slide groove 1513.

[0046] When the frame 1 is pulled and moved, the roller 151 moves synchronously with the connecting rod 1511 and compacts the edge of the mulch film 2. If the ground is uneven, the roller 151 moves up and down with the terrain, causing the connecting rod 1511 to swing around the hinge point, and then the drive rod 1512 slides in the first groove 1513 through the hinge relationship. At this time, the elastic element 1521 will be stretched or compressed due to the relative displacement of the components, generating elastic buffer force. When the ground is raised, the roller 151 is raised, the connecting rod 1511 swings upward, and the elastic element 1521 is compressed or stretched. Its reaction force pushes the roller 151 to maintain the pressure on the mulch film 2, avoiding insufficient compaction due to suspension. When the ground is sunken, the roller 151 sinks, the connecting rod 1511 swings downward, and the elastic element 1521 provides tension or thrust through its own deformation, so that the roller 151 continues to adhere to the ground surface, preventing the mulch film 2 from being damaged by a sudden increase in pressure. This ensures that the roller 151 can maintain stable pressure on the edge of the mulch film 2 through the adaptive adjustment of the elastic element 1521 under different terrains, while buffering the impact of the ground and avoiding the adverse effects of rigid contact.

[0047] In addition to the above-mentioned connection method of elastic element 1521, the two ends of elastic element 1521 can also be respectively sleeved on drive block 152 and connecting rod 1511.

[0048] The sliding engagement between the first chute 1513 and the drive rod 1512 provides guidance and movement space for the swing of the connecting rod 1511, allowing the roller 151 to freely adjust its angle and position according to the terrain, thus enhancing the applicability of the device in complex terrains such as hills and clay. Furthermore, this structure automatically completes pressure compensation through mechanical linkage, eliminating the need for frequent manual adjustments to the height or pressure of the roller 151, reducing manual intervention in field operations, simplifying the operation process, and improving transplanting efficiency. Simultaneously, the design, combining rigidity and flexibility, balances the fixing effect of the mulch film 2 with the structural stability of the equipment itself, creating favorable surface cover conditions for the growth of cabbage seedlings.

[0049] like Figures 4 to 8As shown: The adjustment assembly 153 includes a lead screw 1532 that is disposed beside the first slide groove 1513 and is rotatable. The axis of the lead screw 1532 extends along the length direction of the first slide groove 1513. The drive block 152 is sleeved on the lead screw 1532 and threadedly engaged with it. The frame 1 is provided with a second slide groove 1531 that extends in the horizontal direction. The drive block 152 is slidably disposed on the second slide groove 1531.

[0050] The second slide groove 1531 extending horizontally on the frame 1 provides a sliding guide for the drive block 152, allowing it to move only along the axial direction of the lead screw 1532. When the lead screw 1532 is rotated, the drive block 152, which is sleeved on and threaded onto the lead screw 1532, will move linearly within the second slide groove 1531 along the axial direction of the lead screw 1532 due to the principle of thread transmission. Since the drive block 152 is connected to the elastic element 1521, and the other end of the elastic element 1521 is connected to the drive rod 1512 or the connecting rod 1511, the movement of the drive block 152 will change the initial length of the elastic element 1521, causing it to undergo tensile or compressive deformation, thereby adjusting the magnitude of the elastic force applied by the elastic element 1521 to the drive rod 1512 or the connecting rod 1511.

[0051] The screw 1532, through its threaded engagement with the drive block 152, converts rotational motion into linear motion, enabling precise adjustment of the pre-tension force of the elastic element 1521. This allows for flexible adjustment of the pressure applied by the roller 151 to the edge of the mulch film 2 based on actual working conditions such as the material of the mulch film 2 and the soil type. When working on soft ground such as sandy soil, rotating the screw 1532 moves the drive block 152, reducing the pre-tension force of the elastic element 1521 and preventing the mulch film 2 from sinking into the soil or breaking due to excessive pressure. Conversely, when working on harder ground such as clay, increasing the pre-tension force of the elastic element 1521 ensures that the roller 151 effectively compacts the edge of the film, preventing the mulch film 2 from curling up. This adjustable pressure method allows the device to adapt to different working environments, improving the quality and stability of the mulch film 2 laying. The self-locking characteristic of the screw 1532 transmission ensures that the drive block 152 remains in its current position after adjustment, eliminating the need for additional locking devices, simplifying the operation process, and improving the efficiency of field operations.

[0052] like Figures 4 to 8 As shown: A support rod 154 parallel to the connecting rod 1511 is also provided on the side of the connecting rod 1511, and the support rod 154 is hinged to the frame 1. A support frame 1541 is provided between the bottom of the support rod 154 and the connecting rod 1511, and a rotatable guide wheel 1542 is provided on the support frame 1541.

[0053] When the frame 1 moves along the field under traction, the connecting rod 1511 and the support rod 154 move synchronously with the frame 1. They can swing around the frame 1 through the hinge point to adapt to the undulations of the ground. The support frame 1541 forms a stable connection at the bottom of the connecting rod 1511 and the support rod 154, so that the guide wheel 1542 always keeps in contact with the ground surface. As the frame 1 moves, the guide wheel 1542 rolls on the ground surface, guiding the soil outside the edge of the mulch film 2 or the soil generated by trenching to the edge of the mulch film 2, so that the soil covers and accumulates on the outside edge of the mulch film 2. Combined with the pressure of the roller 151 on the edge of the mulch film 2, it forms a double fixation of the mulch film 2.

[0054] The parallel hinged connection between the support rod 154 and the connecting rod 1511 provides a stable support frame 1541 for the support frame 1541 and the guide wheel 1542. This allows the guide wheel 1542 to adaptively adjust its height according to ground undulations, ensuring it rolls smoothly along the ground surface on fields with varying flatness, evenly guiding the soil to the edge of the mulch film 2 and preventing soil omissions or uneven accumulation due to uneven ground. The guide wheel 1542 is preferably tilted, and its tilt angle is adjustable. The rotational design of the guide wheel 1542 reduces frictional resistance with the soil, allowing it to roll smoothly along with the frame 1. Without additional power, it naturally guides the soil to the edge of the mulch film 2, mechanizing the soil covering process, eliminating the tedious steps of traditional manual soil covering, and reducing labor intensity. The stable structure formed by the support rod 154, connecting rod 1511 and support frame 1541 enhances the overall rigidity and anti-shaking ability of the pressure mechanism 15, makes the soil guiding direction of the guide wheel 1542 more precise, ensures that the edge of the mulch film 2 is effectively covered by soil, further improves the fixing effect of the mulch film 2, reduces the displacement of the film caused by wind or soil moisture changes, and creates a good surface environment for the growth of cabbage seedlings.

[0055] like Figures 1 to 4 and Figure 9 As shown: The punching mechanism 13 includes a rotating roller 131 that is rotatable and mounted on the frame 1. The rotating roller 131 is provided with a plurality of punching columns 1311 that are equidistantly arranged around its axis. The punching columns 1311 extend radially along the rotating roller 131, and the punching heads are all hollow cylindrical structures.

[0056] The rotating roller 131 is rotatably mounted on the frame 1. When the frame 1 moves with traction power, the rotating roller 131 rotates, causing multiple perforated columns 1311, equidistantly distributed around its axis, to rotate synchronously with the rotating roller 131. The perforated columns 1311 extend radially along the rotating roller 131. When the perforating head reaches the position where it contacts the mulch film 2, it pierces the mulch film 2 in the direction of rotation of the rotating roller 131, using the hollow column edges to cut the mulch film 2, forming circular holes matching the diameter of the perforating head. Because the perforated columns 1311 are equidistantly arranged, each rotation of the rotating roller 131 continuously punches multiple evenly distributed holes in the mulch film 2 at a preset interval, forming regularly arranged transplanting holes as the frame 1 moves.

[0057] The equidistant perforated columns 1311 design ensures the uniform distribution of the two holes in the mulch film, which can accurately meet the row spacing and plant spacing requirements for cabbage planting, avoiding the problem of chaotic seedling spacing caused by manual or non-equidistant perforation, and providing a standardized spatial layout for the growth of cabbage seedlings.

[0058] like Figures 1 to 4 and Figure 9 As shown: the rotating roller 131 has a hollow structure, and multiple perforated columns 1311 are connected to the interior of the rotating roller 131. The interior of the rotating roller 131 is provided with a spiral guide bar 1312, and the two ends of the guide bar 1312 are provided with opposite threads. Both ends of the rotating roller 131 are provided with openings 1313.

[0059] As the rotating roller 131 moves with the frame 1 and rotates around its axis, the hollow roller 131 communicates with the outside through openings 1313 at both ends. As the perforating column 1311 rotates and penetrates the plastic film 2, its hollow body guides soil or plastic film 2 debris generated during the perforation process into the roller 131. The spiral guide strip 1312 inside the roller 131 rotates with the roller 131, forming a bidirectional flow guide effect using opposite threads at both ends. When the roller 131 rotates in a preset direction, the guide strip 1312 pushes the soil or debris into the roller 131 through its spiral surface, causing it to move along the axis of the roller 131 towards the openings 1313 at both ends and be discharged, preventing debris from accumulating and clogging inside the roller 131. The interconnected structure between the punching column 1311 and the rotating roller 131 allows the soil generated during punching to enter the rotating roller 131 through the hollow column, and then be guided by the guide strip 1312 to be discharged from the openings 1313 at both ends, ensuring that the hollow channel of the punching column 1311 is always unobstructed and maintaining the stability of continuous punching operation.

[0060] By setting the guide strip 1312, the soil or debris generated by drilling is discharged from the openings 1313 at both ends of the rotating roller 131, avoiding debris from being stuck in the drilling column 1311 or the inside of the rotating roller 131. This eliminates the need for frequent manual cleaning and ensures that the drilling mechanism 13 works continuously and stably. It is especially suitable for scenarios where clay, wet soil and other easily sticky materials are used, reducing downtime and maintenance time caused by blockage.

[0061] like Figures 1 to 3 and Figure 10 As shown: The operating platform 14 includes two slides 141, and the two slides 141 are provided with traction ropes 1411 that are connected to the frame 1.

[0062] The two pallets 141 of the operating platform 14 are connected to the frame 1 via traction ropes 1411. When the frame 1 moves along the field under traction power, the pallets 141 move synchronously with the frame 1 and contact the ground. The traction ropes 1411 provide flexible traction to the pallets 141, allowing them to maintain their relative position to the frame 1 while also swaying or floating slightly with the undulations of the ground. When workers stand or sit on the pallets 141 to place seedlings, the pallets 141, through the traction of the traction ropes 1411, always maintain a suitable operating distance from the holes of the plastic film 2, preventing platform swaying caused by bumps in the frame 1 or uneven ground, and providing a stable working point for personnel.

[0063] like Figures 1 to 3 and Figure 10 As shown: The bottom of the slide plate 141 is provided with a plurality of guide blocks 1412 arranged along its length direction, and the slide plate 141 is provided with a plurality of mounting seats 1413 arranged along its length direction.

[0064] The guide blocks 1412 arranged along the length of the bottom of the pallet 141 contact the ground surface when the pallet 141 moves with the frame 1. The guide blocks 1412 preferably have an inclined or curved surface, which can guide soil, gravel, or weeds encountered during the movement to both sides of the pallet 141, preventing debris from accumulating under the pallet 141, reducing the frictional resistance between the pallet 141 and the ground, and allowing the pallet 141 to move more smoothly with the frame 1. The mounting seats 1413 arranged along the length of the pallet 141 provide adjustable fixed connection points for the staff. According to the operating habits or seedling placement needs, seats, baskets or other auxiliary tools can be added to the mounting seats 1413, making the layout of the operating platform 14 more flexible.

[0065] like Figures 1 to 6 As shown: A method for transplanting cabbage, applied to the aforementioned simple mulched and perforated cabbage transplanting device, includes the following steps:

[0066] S1. Connect the transplanting device to the external power equipment via the traction frame 11 and start it to drive the frame 1 to move along the field operation direction.

[0067] S2. The unwinding mechanism 12 moves along with the frame 1 to release the mulch film 2 and lay it on the ground.

[0068] S3. The roller 151 of the re-pressing mechanism 15 contacts the edge of the mulch film 2 and adjusts the pressure through the adjusting component 153 to compact the edge of the mulch film 2.

[0069] S4. The punching mechanism 13 punches holes in the fixed mulch film 2 at preset intervals to form transplanting holes.
