Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, specifically to a perilla transplanter and its usage method. Background Technology

[0002] Perilla is an important economic crop, and its field cultivation typically employs a method of centralized seedling raising followed by transplanting. With the continuous expansion of perilla cultivation, large-scale transplanting using agricultural machinery has become a primary means of improving production efficiency.

[0003] Currently, most existing transplanting equipment for perilla seedling planting uses an independent motor-driven seedling-laying mechanism or relies entirely on manual labor to continuously place seedlings into the seedling guide tube. This working mode results in a lack of physical and mechanical correlation between the operating rhythm of the seedling-laying device and the field travel speed of the entire transplanting machine. When the travel speed of the traction equipment fluctuates, the time interval for seedling placement cannot change synchronously, easily causing uneven planting spacing in the field, which is detrimental to standardized field management in the later stages of crop growth.

[0004] Furthermore, the functional components of existing transplanting equipment, such as trenching, seedling guiding, soil covering, and compaction, are often structurally dispersed. In actual operation, after the planting trench is dug, the loose soil is prone to premature backflow due to insufficient coordination between the mechanisms, causing changes in the trench depth and preventing the seedlings from accurately falling into the trench at the intended depth.

[0005] Some equipment uses a mechanical clamping structure for seedling arrangement, which can easily cause compression damage to the stems and leaves of tender perilla seedlings when handling them. In addition, the soil covering and compaction processes are relatively delayed, resulting in poor uprightness of the seedlings after they are planted and poor contact between the roots and the soil, thus leading to a low survival rate of seedlings after mechanized transplanting.

[0006] Therefore, this invention proposes a perilla transplanter and its usage method to address the shortcomings of existing technologies. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention provides a perilla transplanter and its usage method, which solves the problems of uneven plant spacing caused by the difficulty in synchronizing the timing of seedling placement and the walking speed of existing perilla transplanting equipment, as well as poor transplanting quality caused by the lack of tight coordination between the trenching, seedling placement, and soil covering actions.

[0008] To achieve the above objectives, the present invention is implemented through the following technical solution: a perilla transplanter, comprising a frame, a furrow opener, ground wheels, a transmission device, a transplanting seedling tray support plate, a seedling dispensing and sowing tray, a seedling dropping box, a soil moisture retainer, and a press. The furrow opener is located at the bottom of the frame. The rear of the furrow opener is fixedly connected to the front side wall of the seedling box. The bottom outlet of the seedling box is located behind the furrow opener and is set corresponding to the center area of ​​the furrow opener. The ground wheel is connected to the seedling dispensing and sowing tray via a transmission device. The seedling dispensing tray is located above and slides against the transplanting tray support plate. The seedling dispensing tray has vertically connected seedling storage cells around its circumference. The transplanting tray support plate has seedling dropping holes that connect with the seedling dropping box. The bottom of the seedling storage cells that are not aligned with the seedling dropping holes is supported and covered by the transplanting tray support plate. The seedling storage cells, seedling dropping holes, and seedling dropping box that are aligned with the seedling dropping holes are vertically connected. The moisture-retaining device and the pressing device are arranged sequentially behind the seedling dropping box.

[0009] Preferably, the bottom of the furrow opener has a downward-protruding pointed structure, and the seedling box has a guide channel extending from top to bottom. The top of the guide channel is connected to the seedling hole, and the bottom of the guide channel is connected to the bottom outlet of the seedling box.

[0010] Preferably, the transmission device includes a drive shaft, a sprocket, and a bevel gear box; the drive shaft is transversely inserted and rotatably connected to the frame, the sprocket is sleeved and fixed to the outside of the drive shaft, and the ground wheel is connected to the sprocket via a chain; the input end of the bevel gear box is connected to the drive shaft, and the output end of the bevel gear box is fixedly connected to the central axis of the seedling dispensing and sowing tray.

[0011] Preferably, the transmission device includes multiple sprockets with different numbers of teeth.

[0012] Preferably, the surface of the frame is fixedly connected to a bearing housing and a connecting and fixing assembly, and the drive shaft passes through the interior of the bearing housing and the connecting and fixing assembly, and the drive shaft is rotatably engaged with the bearing housing and the connecting and fixing assembly.

[0013] Preferably, the transplanting tray support plate is a fixed flat plate structure, the seedling dispensing and sowing tray is a circular disc structure, and multiple seedling storage compartments are arranged at equal angles along the circumference of the seedling dispensing and sowing tray.

[0014] Preferably, the seedling storage grid is a cylindrical, perforated, or grid-like structure that runs vertically through the seedlings.

[0015] Preferably, the soil-closing device includes two soil-covering discs symmetrically arranged on both sides of the frame's travel direction, with the two soil-covering discs located on the left and right sides behind the bottom outlet of the seedling box, respectively.

[0016] Preferably, the rearmost end of the frame is rotatably connected to an extension arm that extends backward, and the press is rotatably connected to the end of the extension arm away from the frame, with the press located directly behind the soil moisture retainer; the upper part of the frame is provided with a seedling box, the side and rear of the frame is provided with a fixed frame, the top of the fixed frame is equipped with a seat, and the front end of the frame is provided with a tractor suspension frame.

[0017] The present invention also provides a method of using the above-mentioned perilla transplanter, comprising the following steps: the traction device pulls the frame to move along the planting direction, and the furrow opener extends into the soil; The ground wheel moves synchronously with the frame and drives the seedling dispensing tray to rotate above the transplanting tray support plate via a transmission device; Place the perilla seedlings into the seedling storage compartment, ensuring that the bottom of the perilla seedlings is on the upper surface of the transplanting tray support plate; When the seedling storage grid is rotated to the top of the seedling dropping hole, the seedling storage grid, the seedling dropping hole and the seedling dropping box are connected vertically. After passing through the seedling dropping hole and the seedling dropping box, the perilla seedlings enter the planting ditch behind the furrow opener. The frame continues to move, the soil compactor passes through the planting furrow, and the roller passes through the area behind the soil compactor.

[0018] This invention provides a perilla transplanter and its method of use. It has the following beneficial effects: 1. This invention uses the ground wheel as the power input component, and directly drives the seedling dispensing and sowing tray to rotate through the transmission device, so that the rotation speed of the sowing tray is mechanically synchronized with the walking speed of the whole machine. It can achieve seedling placement at fixed intervals without the need for electronic control equipment, thus ensuring uniform and consistent plant spacing of perilla seedlings during transplanting.

[0019] 2. This invention employs a seedling arrangement structure where the seedling tray and the transplanting tray support plate are attached vertically. When the seedling storage compartment rotates to be directly above the seedling dropping hole, the bottom support is removed, and the seedlings fall vertically into the seedling dropping box under their own weight. This method uses the relative positional changes of the components to control the timing of seedling descent, avoiding the squeezing damage to the seedlings caused by complex mechanical movements and improving the smoothness of the seedling dropping process.

[0020] 3. This invention integrates the trencher and the seedling box into a single structure, and arranges the soil moisture control device and the compactor sequentially at the rear of the frame. During a single forward movement, the equipment can sequentially and continuously complete trenching, seedling placement, backfilling, and soil compaction. The fixed spatial positions of each component shorten the interval between operations, improving the efficiency of mechanized transplanting and the quality of seedling planting.

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figures 1-9 This embodiment provides a perilla transplanter, including a frame 1, a furrow opener 8, a ground wheel 7, a transmission device 3, a transplanting seedling tray support plate 15, a seedling dispensing and sowing tray 12, a seedling dropping box 9, a soil moisture collector 6, a roller 5, a seedling loading box 2, a fixing frame 16, a seat 4, and a tractor suspension frame 14.

[0025] The frame 1 serves as the basic installation structure for the entire machine, supporting all functional components. The frame 1 can be constructed from welded steel sections to form an integral frame structure, ensuring sufficient structural strength and load-bearing capacity. A tractor suspension frame 14 is fixedly connected to the front end of the frame 1 for connection to external traction equipment. A seedling box 2 with an internal cavity structure is fixedly connected to the upper part of the frame 1 to hold perilla seedlings for easy access by workers. A mounting frame 16 is fixedly connected to the rear side of the frame 1, with a seat 4 mounted on top. In actual use, the tractor connects to the frame 1 via the tractor suspension frame 14 to traction the entire machine. Before operation, workers place a large number of perilla seedlings inside the seedling box 2 so they can sit on the seat 4 to continuously perform seedling placement, improving continuous operation efficiency.

[0026] A furrow opener 8 is installed at the lower part of the frame 1, located in the front area of ​​the machine's travel direction. The bottom of the furrow opener 8 has a downward-protruding pointed structure. Since there are certain requirements for planting depth during the transplanting of perilla seedlings, the installation height of the furrow opener 8 can be adjusted as needed, taking into account the seedling height and root length, to adapt to the transplanting needs of different plots and seedlings of different ages. When the tractor starts moving, the frame 1 moves along the planting direction under traction. During the equipment's forward movement, the furrow opener 8 can first enter the soil layer, cutting and separating the soil to form continuous planting furrows on the ground.

[0027] A ground wheel 7 is rotatably connected to the frame 1, located below the frame 1. The ground wheel 7 not only bears part of the machine's weight but also serves as a power input component. A transmission device 3 is mounted above the frame 1, having a power input end and a power output end. The power input end is connected to the ground wheel 7, and the power output end is connected to the central shaft of the seedling dispensing tray 12. Specifically, the transmission device 3 includes a drive shaft, sprockets 11, and a bevel gear box 13. To accommodate different planting densities, the transmission device 3 includes multiple sprockets 11 with varying numbers of teeth for adjustment. The drive shaft passes laterally through and is rotatably connected to the frame 1. A bearing seat and a connecting assembly 10 are fixedly connected to the frame 1. The drive shaft passes laterally inside the bearing seat and connecting assembly 10, and the drive shaft rotatably engages with the bearing seat and connecting assembly 10. The sprocket 11 is sleeved and fixed to the outside of the drive shaft, and the ground wheel 7 is connected to the sprocket 11 via a chain. The bevel gear box 13 is installed at one end of the drive shaft. The input end of the bevel gear box 13 is connected to the drive shaft, and its output end is fixedly connected to the central shaft of the seedling dispensing and sowing tray 12.

[0028] Once the ground wheel 7 contacts the ground and the tractor begins to move, it continues to roll synchronously throughout the machine's movement due to its continuous contact with the ground. The mechanical power generated by the rotation of the ground wheel 7 drives the chain, which in turn transmits power to the sprocket 11. The sprocket 11 then drives the drive shaft to rotate, and the power is subsequently transmitted to the bevel gear box 13. The bevel gear box 13 converts the transmission direction and outputs the power to the seedling dispensing and sowing tray 12, ensuring a stable transmission of the rotational power from the drive shaft. This drives the seedling dispensing and sowing tray 12 to rotate stably and continuously around its own axis. Since there is no additional power source between the ground wheel 7 and the ground, the power originates entirely from the ground wheel 7. Therefore, the ground wheel 7 always serves as the power reference, and its rotational speed corresponds to the actual travel speed of the equipment. The distance the equipment travels also corresponds to the rotational angle of the seedling dispensing and sowing tray 12. When the equipment's forward speed changes, the rotational speed of the seedling dispensing and sowing tray 12 also changes synchronously. For example, when the tractor speed increases, the rotation speed of the ground wheel 7 increases, and the seedling dispensing and sowing tray 12 rotates at a synchronously faster speed; when the tractor decelerates, the rotation speed of the seedling dispensing and sowing tray 12 decreases accordingly. This allows the seedling dispensing frequency to correspond with the equipment's travel distance, thus enabling subsequent transplanting actions to be synchronized with the travel distance.

[0029] The transplanting tray support plate 15 is a fixed flat plate structure, positioned above the frame 1. The transplanting tray support plate 15 has a plate-like structure with through-holes for seedling placement. The seedling dispensing and sowing tray 12 is a circular structure, positioned above the transplanting tray support plate 15, and maintains a sliding contact with it. The seedling dispensing and sowing tray 12 has multiple through-holes evenly distributed around its circumference, spaced at equal angles. Each storage cell is a through-hole, perforated, or grid-like structure, and its dimensions are designed according to the specifications of the perilla seedlings to ensure stable placement within the cells.

[0030] During the seedling placement process, the staff sits on seat 4, takes seedlings from the seedling box 2, and places them into the seedling storage compartments. Because the storage compartments are evenly distributed circumferentially, sufficient time is provided for the seedling placement operation as the compartments rotate in front of the staff, allowing for continuous placement. After the seedlings enter the storage compartments, their roots face down. At this time, the transplanting tray support plate 15 is located below the storage compartments, supporting the seedlings. As the seedling dispensing tray 12 rotates, most of the storage compartments are above the transplanting tray support plate 15. As the seedling dispensing tray 12 continues to rotate, the bottoms of storage compartments that are not aligned with the seedling placement holes are supported and shielded by the transplanting tray support plate 15, maintaining sliding contact. Therefore, the seedlings are kept inside the storage compartments and do not fall out prematurely.

[0031] The seedling dropping box 9 is located below the transplanting tray support plate 15. It has a guide channel extending downwards, with the top of the guide channel connecting to the seedling dropping hole and the bottom of the guide channel connecting to the bottom outlet of the seedling dropping box 9. This guide channel guides the seedlings downwards, preventing them from shifting outwards during descent. In this embodiment, the rear of the furrow opener 8 is fixedly connected to the front wall of the seedling dropping box 9, forming an integrated structure. The bottom outlet of the seedling dropping box 9 is located behind the furrow opener 8 and corresponds to the central area of ​​the furrow opener 8. This integrated installation method maintains a fixed relative position between the seedling dropping box 9 and the furrow opener 8. During operation, even under ground vibration, the seedling dropping box 9 and the furrow opener 8 maintain a stable positional relationship, and the seedling outlet position always remains consistent with the planting furrow position. This makes the spatial connection between the furrowing and seedling dropping actions more compact, reducing the impact of soil backflow after furrowing on the accuracy of seedling dropping, thus ensuring that the seedlings always fall accurately into the furrow bottom area.

[0032] As a seedling storage cell gradually moves to the position corresponding to the seedling dropping hole (the dropping hole area), the bottom of the cell loses the support of the transplanting tray support plate 15. The seedling storage cell, the dropping hole, and the dropping box 9, aligned with the dropping hole, are vertically connected. The seedling begins to fall under the influence of gravity, first passing through the dropping hole and entering the top entrance of the dropping box 9, moving downwards without being mechanically clamped. When the seedling leaves from the bottom exit of the dropping box 9, the furrow opener 8 has already formed a continuous trench on the ground. The seedling can fall directly and accurately into the bottom area of ​​the trench, presenting a planting state where the roots are inside the soil layer and the stems and leaves are above the trench.

[0033] After the seedlings fall into the planting trench, the equipment continues to move forward. The soil compactor 6 and the compactor 5 are sequentially located behind the seedling box 9. The soil compactor 6 consists of two symmetrically arranged soil-covering discs on both sides of the frame 1 in the direction of travel. These discs are located on the left and right sides behind the bottom outlet of the seedling box 9. The soil compactor 6 then begins to function, with the discs acting on the soil on both sides of the trench as they roll forward, pushing the soil towards the center. As the soil gradually backfills, it covers the area around the seedling roots, securing them and completing the soil covering operation.

[0034] A compactor 5 is installed behind the soil compactor 6. An extension arm is rotatably connected to the rearmost end of the frame 1, and the compactor 5 is rotatably connected to the end of the extension arm furthest from the frame 1, with the compactor 5 located directly behind the soil compactor 6. After the soil covering is completed, the compactor 5 continues to pass through the covered area, using its own weight and rotational contact to moderately compact the surface soil. This compaction reduces soil voids, creating a more stable soil environment around the seedlings, increasing the contact area between the roots and the soil, and allowing for closer contact between the roots and the soil, thus benefiting the subsequent recovery and growth of the seedlings.

[0035] This embodiment achieves a mechanical synchronous transplanting process through the cooperation between the ground wheel 7, the transmission device 3, and the seedling dispensing tray 12. It can complete the fixed-distance seedling placement without the need for an additional electronic control system. At the same time, through the integrated positioning of the furrow opener 8 and the seedling box 9, and the continuous arrangement of the soil compactor 6 and the compactor 5, the positioning, soil covering, and compaction of perilla seedlings can be completed quickly in a single movement, improving the upright stability of the seedlings.

[0036] Please see Figures 1-8 This embodiment provides a method for using a perilla transplanter. Specifically: Before starting the operation, place the perilla seedlings together in the seedling box 2. Check the connection status of the transmission device 3, ground wheel 7, seedling dispensing tray 12, and seedling dropping box 9. After confirming that all components are working properly, connect the tractor suspension frame 14 to the external traction equipment.

[0037] After the traction equipment is started, the traction frame 1 moves along the planting direction. The furrow opener 8 first extends into the soil and cuts the soil with its downward-protruding pointed structure. As it continues to move forward, the furrow opener 8 gradually forms a planting furrow with a relatively stable width and depth.

[0038] At the same time, the ground wheel 7 moves synchronously with the frame 1 and drives the seedling dispensing and sowing tray 12 to rotate above the transplanting tray support plate 15 via the transmission device 3. That is, the rotational power output by the ground wheel 7 is transmitted to the sprocket 11 through the chain, and then input to the bevel gear box 13 through the transmission shaft. The bevel gear box 13 drives the seedling dispensing and sowing tray 12 to rotate at a uniform speed.

[0039] The staff member sits on seat 4 and places the perilla seedlings into the seedling storage compartment, ensuring that the bottom of the perilla seedling is on the upper surface of the transplanting tray support plate 15. Since multiple seedling storage compartments are evenly arranged in a circular direction, after one seedling storage compartment leaves the seedling loading area, the next seedling storage compartment will arrive at the seedling loading position in sequence, thus ensuring continuous seedling loading.

[0040] After the seedlings are placed in the seedling storage compartment, their weight is supported by the transplanting tray support plate 15. Since the bottom surface of the seedling dispensing tray 12 and the upper surface of the transplanting tray support plate 15 remain in sliding contact, the seedlings can move synchronously with the seedling dispensing tray 12. During this process, the seedling storage compartment mainly serves to separate and contain the seedlings, without rigidly clamping them.

[0041] When the seedling storage grid rotates to the position above the seedling dropping hole, the storage grid, the dropping hole, and the dropping box 9 are connected vertically. At this point, the seedling loses its supporting function and begins to fall. Because the dropping hole is vertically connected, the seedling can smoothly pass through the dropping hole and enter the dropping box 9.

[0042] The seedling box 9 forms a downward-extending guide channel inside. After passing through the seedling hole and the seedling box 9, the perilla seedlings enter the planting ditch behind the furrow opener 8. Since the bottom outlet of the seedling box 9 is located behind the furrow opener 8, the seedlings fall exactly to the center of the planting ditch. The seedling box 9 and the furrow opener 8 are fixed together to avoid significant relative displacement between them due to vibration, impact or assembly deviation.

[0043] After the seedlings enter the planting trench, their roots first come into contact with the soil at the bottom of the trench. The frame 1 continues to move, and the soil-closing device 6 passes through the planting trench. The two soil-covering discs push the soil from the left and right sides toward the middle, so that the roots of the seedlings are gradually covered by the soil.

[0044] After the soil covering is completed, the compactor 5 compacts the soil in the area behind the soil compactor 6. The compacted soil can reduce the loosening caused by factors such as wind and water erosion, and at the same time improve the upright stability of the seedlings. Through the continuous connection between soil covering and compaction, the roots of the perilla seedlings can adhere to the soil more quickly, reducing the risk of seedling tilting and lodging.

[0045] During continuous operation, staff can replenish seedlings according to the availability of seedling storage compartments. Since the seedling dispensing tray 12 rotates continuously, continuous seedling filling can be completed without stopping the machine. The seedling container 2 can store a certain number of seedlings, thereby reducing the frequency of refilling.

[0046] For different planting density requirements, adjustments can be made by replacing the sprocket 11 with a different number of teeth or by adjusting the transmission ratio parameters. When the rotation speed of the seedling dispensing tray 12 decreases, the distance between adjacent seedlings increases; when the rotation speed of the seedling dispensing tray 12 increases, the distance between adjacent seedlings decreases, thereby adapting to the needs of different planting schemes.

[0047] During field turns or brief pauses, the ground wheels 7 stop rolling, the transmission device 3 stops working simultaneously, and the seedling dispensing tray 12 stops rotating, thus preventing ineffective seedling drop. When the equipment resumes forward movement, the entire transmission system re-enters the working state and continues to complete the transplanting operation.

[0048] During long-term continuous operation, the bearing housing and connecting and fixing assembly 10 can provide stable support for the drive shaft, reduce the swaying of the drive shaft, and the bevel gear box 13 can continuously maintain the stability of power transmission, so that the seedling dispensing and sowing tray 12 can maintain a stable rotation state.

[0049] Through the continuous and coordinated operation of the frame 1, furrow opener 8, ground wheel 7, transmission device 3, transplanting seedling tray support plate 15, seedling dispensing and sowing tray 12, seedling dropping box 9, soil moisture acclimator 6, and compactor 5, the operation steps of furrow opening, seedling conveying, seedling dropping, soil covering, and compaction can be completed in sequence, realizing continuous transplanting of perilla seedlings, improving transplanting efficiency and reducing manual labor intensity. During the entire operation, the various mechanisms mainly rely on mechanical transmission to complete the action connection, and stable operation can be achieved without complex control equipment, which is suitable for large-scale perilla planting operation scenarios.
