Description

Technical Field

[0001] This utility model relates to the field of agricultural planting technology, and in particular to a seedling tray storage device and a transplanter using the seedling tray storage device. Background Technology

[0002] Transplanters are used to automatically or semi-automatically transplant pre-grown seedlings from seedling trays into fields. During transplanting, workers sit on the machine, removing seedlings one by one from the trays and placing them into receiving tubes within the seedling conveying mechanism. These seedlings are then transported to the transplanting mechanism for successful transplanting. However, each seedling tray contains a limited number of seedlings, so many trays are typically placed on the machine during operation. Currently, transplanters lack dedicated seedling tray storage devices, resulting in trays being piled up haphazardly. This disorderly stacking easily causes trays to collide with each other, damaging the roots and stems of the seedlings and affecting the survival rate. Furthermore, the lack of an effective storage structure limits the number of seedling trays that can be placed on the machine, requiring frequent stops to replenish the trays, severely impacting transplanting efficiency. Utility Model Content

[0003] The main purpose of this utility model is to provide a seedling tray storage device and a transplanter using the seedling tray storage device, which aims to store seedling trays in an orderly manner, protect seedlings, and improve work efficiency.

[0004] To achieve the above objectives, the seedling tray storage device proposed in this utility model is installed on one side of the transplanter, and the seedling tray storage device includes:

[0005] A storage box, wherein the storage box has a storage cavity that runs through the top and bottom, and a sliding groove is provided on one side of the storage box;

[0006] Multiple seedling trays are provided in the storage cavity. A slider is provided on one side of each seedling tray. The slider is slidably connected to the sliding groove. A fixing rod protrudes from one side of the slider.

[0007] A support feeding assembly is located on one side of the sliding groove. The support feeding assembly includes multiple rotating fans, each fan including a rotating shaft and multiple fan blades. The rotating shaft is rotatably disposed on the outer side wall of the storage box. A fixing rod extends into the rotating fan, so that the fan blades support the fixing rod.

[0008] The rotation of multiple rotating fans causes multiple seedling trays to slide downwards without support, with the bottommost seedling tray falling out of the storage box, and the remaining seedling trays being supported by another blade of the rotating fan after descending one position.

[0009] In one embodiment, the support feeding assembly includes:

[0010] Multiple gears, the gears being fixed to the rotating shaft;

[0011] A rack, which meshes with a plurality of the gears;

[0012] A driving device is provided to drive the rack to move, thereby driving the gear and the rotating fan to rotate.

[0013] In one embodiment, a hook portion is provided at the end of the fan blade, and the hook portion is in a horizontal state when supporting the fixing rod.

[0014] In one embodiment, a slider is also provided on the side of the seedling tray opposite to the fixing rod, and the slider is slidably connected to the side wall of the storage box.

[0015] In one embodiment, the seedling tray storage device further includes a receiving component located below the storage box, the receiving component comprising:

[0016] A receiving plate is located directly below the storage box, and the receiving plate is inclined.

[0017] An operating table is located at the bottom end of the receiving plate and is inclined.

[0018] After the receiving plate receives the seedling tray, the seedling tray slides to the operating table with the tilt angle. The worker will then take the seedlings from the seedling tray on the operating table and place the seedlings into the receiving tube.

[0019] In one embodiment, the receiving plate is provided with a plurality of rollers.

[0020] In one embodiment, the receiving assembly further includes a recycling bin located below the operating table, the operating table comprising:

[0021] A fixing frame, wherein the fixing frame has an opening on one side facing the receiving plate;

[0022] A sliding support plate is slidably disposed on the side wall of the fixed frame, and the sliding support plate is used to support the seedling tray;

[0023] A spring, located between the fixed frame and the sliding support plate;

[0024] After the worker finishes processing the seedlings in the seedling tray, he pulls the sliding support plate, causing the seedling tray to fall into the recycling bin without support.

[0025] In one embodiment, the bottom of the sliding support plate is provided with a protrusion, and the inner sidewall of the fixed frame is provided with a sensor. When the sliding support plate moves outward, the protrusion contacts the sensor to sense a signal, and the sensor transmits the signal to the driving device, which drives the rack to move.

[0026] In one embodiment, the edge of the opening on one side of the fixing frame is provided with a guide bevel.

[0027] This utility model also provides a transplanter, which includes the seedling tray storage device described above.

[0041] Please see Figures 1 to 3This application discloses a seedling tray storage device 1000, which is installed on one side of a transplanter and includes a storage box 1, multiple seedling trays 2, and a support and feeding assembly 3. The storage box 1 has a storage cavity that extends vertically, and a sliding groove is opened on one side. The seedling trays 2 are placed in the storage cavity, and a slider 21 is provided on one side of the seedling tray 2. The slider 21 is slidably connected to the sliding groove, and a fixing rod 22 protrudes from one side of the slider 21. The support and feeding assembly 3 is located on one side of the sliding groove and includes multiple rotating fans 31. Each rotating fan 31 includes a rotating shaft 311 and multiple fan blades 312. The rotating shaft 311 is rotatably disposed on the outer wall of the storage box 1, and the fixing rod 22 extends into the rotating fan 31, so that the fan blades 312 support the fixing rod 22. When the multiple rotating fans 31 rotate, the multiple seedling trays 2 slide downwards without support, so that the bottom seedling tray 2 falls out of the storage box 1, and the remaining seedling trays 2 are stopped and supported by another fan blade 312 after falling one position.

[0042] Specifically, the storage box 1 can be made of metal or high-strength plastic, and the size of its internal storage cavity can be adjusted according to the size of the seedling tray 2. The width of the sliding groove is slightly larger than the thickness of the slider 21 to ensure that the slider 21 can slide smoothly. The slider 21 of the seedling tray 2 can be fixed to one side of the seedling tray 2 by welding or bolting. The fixing rod 22 can be cylindrical or square, and its length should be sufficient to extend into the rotating fan 31. The fan blades 312 of the rotating fan 31 can be arc-shaped or straight, and the number of fan blades 312 can be adjusted as needed, usually set to 3-5. The rotating shaft 311 can be mounted on the outer wall of the storage box 1 by bearings to ensure that it can rotate smoothly. As a preferred embodiment, the end of the fan blade 312 can be provided with a hook part 3121, which is in a horizontal state when supporting the fixing rod 22 to enhance the support stability.

[0043] Therefore, this technical solution achieves layer-by-layer support and release of the seedling trays 2 through the rotating fan 31 supporting the feeding component 3, solving the problems of seedling damage caused by random stacking of seedling trays 2 and the need for frequent machine stops to reload in the prior art. Specifically, the rotation of the rotating fan 31 causes the seedling trays 2 to fall layer by layer, with the bottommost seedling tray 2 being released first, and the remaining seedling trays 2 being supported by the next layer of fan blades 312, achieving orderly feeding of the seedling trays 2. Furthermore, the device has a simple structure, is easy to operate, and can effectively improve the working efficiency of the transplanter and reduce manual intervention. Compared with the prior art, this device achieves automatic feeding of the seedling trays 2 through mechanization, avoiding the instability of manual stacking, while increasing the number of seedling trays 2 that can be stored and reducing the number of downtimes.

[0044] Please see Figure 2 and Figure 3Furthermore, this application also proposes that the support feeding assembly 3 includes multiple gears 32, a rack 33, and a drive device 34. The gears 32 are fixed on the rotating shaft 311, the rack 33 meshes with the multiple gears 32, and the drive device 34 is used to drive the rack 33 to move, so as to drive the gears 32 and the rotating fan 31 to rotate.

[0045] Specifically, gear 32 can be a spur gear 32 or a helical gear 32, rack 33 can be a straight rack 33 or an arc rack 33, and drive device 34 can be an electric actuator, a hydraulic cylinder, or a pneumatic cylinder. As a preferred embodiment, drive device 34 can be controlled by a manual switch or automatically via a sensor signal 424.

[0046] Therefore, this technical solution achieves synchronous rotation of the rotating fan 31 through gear 32 and rack 33 transmission, solving the problems of low efficiency and difficulty in ensuring synchronous movement of multiple rotating fans 31 in manual operation. The gear 32 and rack 33 transmission features simple structure and high transmission precision, ensuring consistent rotation angles of multiple rotating fans 31, thus guaranteeing the stability and reliability of seedling tray 2 feeding. Furthermore, the use of the drive device 34 reduces the labor intensity of manual operation and improves the degree of automation. Compared with existing technologies, this solution achieves mechanization and precise control of the seedling tray 2 feeding process.

[0047] Please see Figure 2 and Figure 3 Furthermore, this application also proposes that the end of the fan blade 312 is provided with a hook portion 3121, which is in a horizontal state when supporting the fixing rod 22.

[0048] Specifically, the hook portion 3121 is a hook-shaped structure formed by bending inward at the end of the fan blade 312, and its bending angle matches the diameter of the fixing rod 22. In a preferred embodiment, the hook portion 3121 can be manufactured using metal stamping or injection molding processes, and its inner surface can be provided with anti-slip textures to enhance friction. Furthermore, the hook portion 3121 and the main body of the fan blade 312 can be fixed by welding or bolting. When the rotating fan 31 is in the supported position, the opening of the hook portion 3121 faces upward, forming a stable supporting plane, allowing the fixing rod 22 to rest stably on the horizontal section of the hook portion 3121.

[0049] Therefore, this technical solution effectively solves the problem of possible sliding or displacement of the seedling tray 2 in the supported state by setting a hook part 3121 with a specific structure. The horizontal support surface of the hook part 3121 can ensure that the fixing rod 22 maintains stable contact and prevent the seedling tray 2 from accidentally slipping off due to vibration or movement.

[0050] Please see Figure 2Furthermore, this application also proposes that a slider 21 is provided on the side of the seedling tray 2 opposite to the fixing rod 22, and the slider 21 is slidably connected to the side wall of the storage box 1.

[0051] Specifically, the slider 21 is made of metal or high-strength plastic, and its cross-sectional shape is T-shaped or rectangular, forming a sliding fit with the groove on the side wall of the storage box 1. In a preferred embodiment, the slider 21 is fixedly connected to the seedling tray 2 by bolts or integrally injection molded. A lubricating coating can be applied to the surface of the slider 21 to reduce frictional resistance. The symmetrically arranged groove structure on both sides of the storage box 1 ensures that the seedling tray 2 remains horizontal during descent, preventing tilting and jamming.

[0052] Therefore, by symmetrically arranging sliders 21 on both sides of the seedling tray 2, the movement trajectory of the seedling tray 2 within the receiving cavity is made more stable. When the rotating fan 31 drives the seedling tray 2 to fall layer by layer, the coordinated action of the two sliders 21 effectively prevents the seedling tray 2 from deflecting or wobbling, ensuring that the fixing rod 22 can accurately fall into the hook part 3121 of the rotating fan 31. This design solves the problem of unstable center of gravity of the seedling tray 2 caused by unilateral support, while reducing the wear rate of sliding parts and extending the service life of the device. Compared with the prior art, this solution significantly improves the smoothness and reliability of the seedling tray 2's feeding.

[0053] Please see Figure 1 , Figure 4 , Figure 5 Furthermore, this application also proposes that the seedling tray storage device 1000 further includes a receiving component 4, located below the storage box 1. The receiving component 4 includes a receiving plate 41 and an operating table 42. The receiving plate 41 is located directly below the storage box 1 and is inclined. The operating table 42 is located at the bottom end of the receiving plate 41 and is also inclined. After the receiving plate 41 receives the seedling tray 2, the seedling tray 2 slides to the operating table 42 according to the tilt angle. The worker will then remove the seedlings from the seedling tray 2 on the operating table 42 and place the seedlings into the receiving tube.

[0054] Specifically, the receiving plate 41 can be made of metal sheet or high-strength plastic sheet, and the tilt angle is preferably 15-30 degrees. The tilt angle of the operating table 42 can be the same as or slightly smaller than that of the receiving plate 41 to facilitate worker operation. As a preferred embodiment, the surface of the receiving plate 41 can be provided with anti-slip texture or rubber pads to slow down the downward speed of the seedling tray 2. Furthermore, the edge of the operating table 42 can be provided with a guard to prevent the seedling tray 2 from slipping. The receiving plate 41 and the operating table 42 can be connected by welding or bolts to ensure structural stability.

[0055] Therefore, this technical solution, by setting up an inclined receiving plate 41 and an operating platform 42, realizes the automatic transport of the seedling tray 2 from the storage box 1 to the operating platform 42. When the seedling tray 2 falls from the storage box 1, it is first caught by the receiving plate 41 and then slides along the inclined surface to the operating platform 42 under the action of gravity. Workers only need to operate from a fixed position, without the need for frequent movement or posture adjustments. This not only improves seedling retrieval efficiency but also reduces labor intensity. At the same time, the inclined receiving plate 41 and operating platform 42 ensure the smooth sliding of the seedling tray 2, preventing damage to the seedlings due to violent vibrations. Compared with the existing technology of randomly stacking the seedling trays 2, this solution achieves the orderly transport and positioning of the seedling trays 2, providing workers with a stable operating platform.

[0056] Please see Figure 4 Furthermore, this application also proposes that the receiving plate 41 is provided with a plurality of rollers 411.

[0057] Specifically, the rollers 411 can be made of metal or engineering plastic, with a preferred diameter range of 20-50 mm, and the spacing between adjacent rollers 411 is controlled at 5-15 mm. The rollers 411 are mounted on supports on both sides of the receiving plate 41 via bearings, allowing for free rotation. As a preferred embodiment, the surface of the rollers 411 can be provided with anti-slip textures or a rubber coating to adjust the sliding speed of the seedling tray 2. Furthermore, the arrangement direction of the rollers 411 is consistent with the tilt direction of the receiving plate 41, ensuring that the seedling tray 2 slides along a predetermined trajectory.

[0058] Therefore, by setting up a receiving plate 41 with rollers 411, the frictional resistance of the seedling tray 2 during its descent can be significantly reduced, avoiding seedling damage caused by jamming. Compared with a flat slide, the roller 411 structure allows the seedling tray 2 to maintain a uniform and stable descent, ensuring both operational efficiency and improving the success rate of seedling transplanting. This design is particularly suitable for continuous operation scenarios and can effectively solve the technical problem of seedling tray 2 easily accumulating in traditional receiving devices.

[0059] Please see Figure 1 , Figure 4 , Figure 5 Furthermore, this application also proposes that the receiving component 4 further includes a recycling bin 43, located below the operating table 42. The operating table 42 includes a fixed frame 421, a sliding support plate 422, and a spring 423. The fixed frame 421 has an opening on one side facing the receiving plate 41. The sliding support plate 422 is slidably disposed on the side wall of the fixed frame 421 and is used to support the seedling tray 2. The spring 423 is located between the fixed frame 421 and the sliding support plate 422. After the worker finishes processing the seedlings in the seedling tray 2, he pulls the sliding support plate 422, causing the seedling tray 2 to lose its support and fall into the recycling bin 43.

[0060] Specifically, the sliding support plate 422 can be slidable using a structure that combines a guide rail and a sliding groove, allowing it to move smoothly along the side wall of the fixed frame 421. The spring 423 can be a compression spring or a torsion spring, and its elastic coefficient needs to be appropriately selected based on the weight of the seedling tray 2 to ensure that the sliding support plate 422 can automatically return to its original position when no external force is applied. The recycling box 43 can be made of metal or plastic, and its volume must be sufficient to accommodate the stacking of multiple empty seedling trays 2. Rubber buffer pads can be installed at the opening edge of the fixed frame 421 to reduce the impact when the seedling trays 2 fall.

[0061] In a preferred embodiment, the bottom of the sliding support plate 422 is provided with a protrusion 4221, and the inner sidewall of the fixed frame 421 is provided with a sensor 424. When the sliding support plate 422 moves outward, the protrusion 4221 contacts the sensor 424 to sense a signal, and the sensor 424 transmits the signal to the drive device 34, which drives the rack 33 to move. This realizes the linkage control of the feeding and recycling of the seedling tray 2, improving the degree of automation.

[0062] To address this, the technical solution utilizes a sliding support plate and a recycling bin 43 to automatically recycle empty seedling trays 2, avoiding the tedious manual handling. The spring 423 structure ensures the support plate automatically resets after each recycling operation, preparing for the placement of the next seedling tray 2. Compared to existing technologies, this design simplifies the operation process, improves work efficiency, and reduces the risk of damage to the seedling trays 2 during transfer. The opening design of the fixing frame 421 facilitates the smooth sliding of the seedling trays 2, while the sensor 424 enables coordinated control of feeding and recycling.

[0063] Please see Figure 4 , Figure 5 Furthermore, this application also proposes that the bottom of the sliding support plate 422 is provided with a protrusion 4221, and the inner sidewall of the fixed frame 421 is provided with a sensor 424. When the sliding support plate 422 moves outward, the protrusion 4221 contacts the sensor 424 to sense a signal. The sensor 424 transmits the signal to the drive device 34, and the drive device 34 drives the rack 33 to move.

[0064] Specifically, the protrusion 4221 is a protruding structure made of metal or plastic, and its shape can be cylindrical, square, or wedge-shaped. It is used to trigger the sensor 424 when the sliding support plate 422 moves to a set position. The sensor 424 can be a contact microswitch, a photoelectric sensor 424, or a Hall sensor 424, and is installed at a preset position on the inner sidewall of the fixed frame 421 to detect the displacement signal of the protrusion 4221. After receiving the signal from the sensor 424, the drive device 34 drives the rack 33 to move linearly through a motor or cylinder, thereby driving the gear 32 and the rotating fan 31 to rotate. As a preferred embodiment, the sensor 424 and the drive device 34 are connected via wired signal transmission or a wireless communication module to ensure the real-time nature of signal transmission.

[0065] Therefore, this technical solution achieves automated control of the seedling tray 2 feeding process through a combination of mechanical triggering and electronic control linkage. When the worker pulls the sliding support plate 422, the protrusion 4221 triggers the sensor 424, and the drive device 34 immediately starts the rotating fan 31 to rotate, causing the upper seedling tray 2 to automatically fall and fill the empty space. Compared with the manual operation of the drive device 34, this design significantly reduces the number of operation steps and avoids the problem of seedling tray 2 piling up or empty spaces due to operation delays. At the same time, the precise detection of the displacement of the sliding support plate 422 by the sensor 424 ensures that the drive device 34 only starts when the seedling tray 2 is completely detached from the support state, preventing mechanical jamming caused by erroneous operation.

[0066] Please see Figure 4 , Figure 5 Furthermore, this application also proposes that a guide slope be provided on one side of the opening edge of the fixed frame 421.

[0067] The guide slope is an inclined transition structure, and its inclination angle can be set from 30° to 60° according to actual needs. The guide slope can be formed by stamping metal sheet or manufactured by plastic injection molding. The surface of the guide slope can be polished to reduce the coefficient of friction, or a wear-resistant coating can be added to extend its service life. The width of the guide slope is preferably 1.2-1.5 times the thickness of the seedling tray 2 to ensure smooth sliding of the seedling tray 2. As a preferred embodiment, the guide slope and the fixing frame 421 are detachably connected for easy maintenance and replacement. Specifically, this technical solution effectively solves the problem of jamming that may occur when the seedling tray 2 moves on the sliding support plate 422 by setting the guide slope.

[0068] This utility model also provides a transplanting machine, which includes the seedling tray storage device 1000 of the above embodiments. The specific structure of the seedling tray storage device 1000 is as described in the above embodiments. Since this transplanting machine adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here.
