Description

Technical Field

[0001] This utility model relates to the field of plant tissue culture technology, and in particular to a plant seedling tissue culture device. Background Technology

[0002] Currently, plant tissue culture is a common biological propagation technique. Typically, under sterile conditions, the totipotency of plant cells is utilized to regenerate complete plants by culturing plant tissues, cells, or organs in vitro.

[0003] During the cultivation process, plant seedlings are supported in petri dishes and placed in an incubator. Seedlings in different positions receive varying light intensities from plant growth lamps, resulting in poor uniformity of seedling growth. For example, Chinese utility model patent CN220343150U, with authorization announcement date of January 16, 2024, discloses a Dendrobium tissue culture inoculation tool, including a base, a limiting ring fixedly mounted on the top of the base, a support plate fixedly mounted on the outer edge of the base, a motor fixedly mounted on the top of the support plate, a power output shaft of the motor rotatably connected to a power belt, a support column rotatably connected inside the power belt, a support frame fixedly mounted on the outer wall of the support column, and a culture ring fixedly mounted on the outer edge of the support frame.

[0004] Existing Dendrobium tissue culture inoculation tools are designed with a motor, support column, and support frame. The rotation of the support column drives the culture ring to rotate, ensuring that the Dendrobium seedlings receive light evenly. However, in order to ensure the stability of the culture dish during rotation, the culture dish needs to be reliably fixed on the culture ring, which makes it difficult to remove and operate, and inconvenient to add nutrient solution regularly and observe the growth status of seedlings. Utility Model Content

[0005] The technical problem to be solved by this utility model is that in order to ensure the stability of the position of the culture dish during rotation, the culture dish needs to be reliably fixed on the culture ring, which makes it difficult to remove and operate, and inconvenient to add nutrient solution regularly and observe the growth status of seedlings.

[0006] To solve the above-mentioned technical problems, this utility model provides a technical solution for a plant seedling tissue culture device:

[0007] The plant seedling tissue culture device includes a tissue culture box, a main shaft, a first boss, a second boss, multiple bearing plates, and multiple connecting rod structures. The main shaft is rotatably installed in the tissue culture box, and the rotation axis of the main shaft extends vertically.

[0008] The first boss and the second boss are fixed to the main shaft at an interval between them. A plurality of the bearing plates are arranged circumferentially around the first boss. One end of the bearing plate is hinged to the first boss, and the other end of the bearing plate extends out of the second boss.

[0009] The support plate has a limiting hole near the first boss, the limiting hole is through the thickness direction of the support plate and is used to position and cooperate with the culture dish; the connecting rod structure is disposed on the lower side of the support plate and is rotatably connected to the second boss;

[0010] The linkage structure includes a tray that corresponds to the limiting hole. When pressed, the linkage structure causes the tray to protrude out of the limiting hole. An elastic element is also installed between the support plate and the second protrusion. When released, the elastic element drives the support plate to reset and causes the tray to exit the limiting hole through the linkage structure.

[0011] Furthermore, the linkage structure includes a first linkage and a second linkage, the second linkage being spaced apart on the lower side of the bearing plate, and the middle part of the second linkage being rotatably connected to the second boss;

[0012] The first connecting rod is hinged to one end of the second connecting rod and corresponds to the limiting hole, and the tray is fixedly installed on the upper part of the first connecting rod.

[0013] Furthermore, the linkage structure also includes a third linkage, which is hinged between the other end of the second linkage and the bearing plate.

[0014] Furthermore, a support is fixedly installed on the second protrusion, the support being spaced apart on the lower side of the middle of the bearing plate, and the elastic element is a top compression spring, which is connected between the bearing plate and the support.

[0015] Furthermore, the support is a U-shaped support with a central channel, and the second connecting rod is rotatably mounted on the central channel of the support.

[0016] Furthermore, the upper surface of the support plate is provided with a guide groove extending radially along the main axis, the guide groove being used to guide and engage with the culture dish.

[0017] Furthermore, the support plate includes a first segment and a second segment, the first segment is hinged to the first boss, and the limiting hole is opened in the first segment; the second segment is fixedly connected to the first segment and extends obliquely downward.

[0018] Furthermore, the first boss has multiple first grooves, which are circumferentially spaced apart. One end of each of the multiple bearing plates is hinged to a first groove. The second boss has multiple second grooves, which are arranged radially opposite to the first grooves along the main shaft. The connecting rod structure and the support are both disposed in the second grooves.

[0019] Furthermore, it also includes a ring light, which is sleeved on the outside of the main shaft. The ring light is arranged vertically and horizontally with the support plate, and a lamp holder is fixedly connected between the ring light and the tissue culture box.

[0020] Furthermore, it also includes a drive motor, which is fixedly installed on the tissue culture box. The motor shaft of the drive motor is connected to a first gear to prevent rotation, and the end of the main shaft is connected to a second gear to prevent rotation. The first gear and the second gear mesh with each other.

[0021] Compared with existing technologies, the plant seedling tissue culture device of this utility model has the following advantages: The device adopts a design consisting of a tissue culture box, a main shaft, a first boss, a second boss, multiple support plates, and multiple connecting rod structures. The main shaft is rotatably installed in the tissue culture box. The first and second bosses are fixed to the main shaft at intervals. Multiple support plates are arranged circumferentially around the first boss. The connecting rod structures are located on the lower side of the support plates and rotatably connected to the second boss. The multiple support plates provide multiple circumferentially distributed installation positions for the culture dishes. By rotating the first boss, the second boss, and the support plates through the main shaft, the light angle and the position of the support plates can be adjusted, ensuring uniform light exposure and facilitating the removal of culture dishes from different positions.

[0022] The support plate has a limiting hole near the first protrusion. The tray with the linkage structure corresponds to the limiting hole. This design, using the matching of the limiting hole and the tray, allows the tray to protrude from the limiting hole when pressed, accurately ejecting the culture dish. Simultaneously, the pressing force drives the support plate to rotate downwards to an inclined position, allowing the culture dish to slide smoothly along the support plate, achieving a "one-click" separation and removal operation. When released, the elastic element drives the support plate to rotate upwards to reset. Through the lever principle of the linkage structure, the tray moves downwards, disengaging from the limiting hole to allow the culture dish to be placed in the hole. At the same time, the tray, positioned below the limiting hole, reliably stops the culture dish, ensuring its positional stability.

[0023] This plant seedling tissue culture device makes full use of the three-dimensional space of the tissue culture box, increasing the seedling capacity of a single unit. The limiting holes of the support plate, in conjunction with the tray, not only ensure the stable and reliable placement of the culture dish, but also allow the culture dish to be ejected with a single press of the support plate, effectively simplifying the removal operation and avoiding the difficulty of removal caused by rigidly fixed culture dishes. It also facilitates the regular addition of nutrient solution to the culture dish and the observation of seedling growth. Attached Figure Description

For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0033] like Figs. 1 to 4 As shown, a plant seedling tissue culture device according to an embodiment of the present invention includes a tissue culture box 1, a main shaft 2, a first boss 3, a second boss 4, multiple support plates 5, and multiple connecting rod structures 6. The main shaft 2 is rotatably installed in the tissue culture box 1, and the rotation axis of the main shaft 2 extends vertically. The first boss 3 and the second boss 4 are fixed to the main shaft 2 at intervals. Multiple support plates 5 are arranged circumferentially around the first boss 3. One end of the support plate 5 is hinged to the first boss 3, and the other end of the support plate 5 extends outward to the outside of the second boss 4.

[0034] A limiting hole 50 is provided near the first boss 3 on the support plate 5. The limiting hole 50 extends along the thickness direction of the support plate 5 and is used for positioning and engaging with the petri dish. A connecting rod structure 6 is provided on the lower side of the support plate 5 and is rotatably connected to the second boss 4. The connecting rod structure 6 includes a tray 60, which corresponds to the limiting hole 50. When pressed, the tray 60 is driven to protrude out of the limiting hole 50 through the connecting rod structure 6. An elastic element 51 is also installed between the support plate 5 and the second boss 4. When released, the elastic element 51 drives the support plate 5 to reset and drives the tray 60 to exit the limiting hole 50 through the connecting rod structure 6.

[0035] This plant seedling tissue culture device employs a design consisting of a tissue culture box 1, a main shaft 2, a first boss 3, a second boss 4, multiple support plates 5, and multiple connecting rod structures 6. The main shaft 2 is rotatably mounted within the tissue culture box 1. The first boss 3 and the second boss 4 are fixed vertically to the main shaft 2 at intervals. Multiple support plates 5 are arranged circumferentially around the first boss 3. The connecting rod structures 6 are located on the underside of the support plates 5 and are rotatably connected to the second boss 4. The multiple support plates 5 provide multiple circumferentially distributed mounting positions for the culture dishes. By rotating the first boss 3, the second boss 4, and the support plates 5 via the main shaft 2, the light angle and the position of the support plates 5 can be adjusted, ensuring uniform light exposure and facilitating the removal of culture dishes from different positions.

[0036] The support plate 5 has a limiting hole 50 near the first protrusion 3. The tray 60 of the connecting rod structure 6 corresponds to the limiting hole 50. The combination of the limiting hole 50 and the tray 60 allows the tray 60 to protrude from the limiting hole 50 when pressed, accurately ejecting the culture dish. Simultaneously, the pressing force drives the support plate 5 to rotate downwards to an inclined state, allowing the culture dish to slide smoothly along the support plate 5, achieving a "one-click" separation and removal operation. When released, the elastic element 51 drives the support plate 5 to rotate upwards and reset. Through the lever principle of the connecting rod structure 6, the tray 60 moves downwards, allowing the tray 60 to exit the limiting hole 50 for the culture dish to be placed in the hole. At the same time, the tray 60 provides a reliable stop for the culture dish below the limiting hole 50, ensuring the positional stability of the culture dish.

[0037] This plant seedling tissue culture device makes full use of the three-dimensional space of the tissue culture box 1, increasing the seedling capacity of a single unit. The limiting hole 50 of the support plate 5 and the tray 60 work together to ensure that the placement of the culture dish is stable and reliable. Moreover, the culture dish can be pushed out with one press of the support plate 5, which effectively simplifies the removal operation and avoids the difficulty of removal caused by the rigid fixation of the culture dish. It also makes it convenient to add nutrient solution to the culture dish regularly and observe the growth status of the seedlings.

[0038] In this embodiment, the linkage structure 6 includes a first linkage 61 and a second linkage 62. The second linkage 62 is spaced apart on the lower side of the support plate 5, and its middle part is rotatably connected to the second boss 4. The first linkage 61 is hinged to one end of the second linkage 62 and corresponds to the limiting hole 50. The tray 60 is fixedly installed on the upper part of the first linkage 61. Furthermore, the linkage structure 6 also includes a third linkage 63, which is hinged between the other end of the second linkage 62 and the support plate 5. When pressed or released, the third linkage 63 and the second linkage 62 transmit power between the support plate 5 and the first linkage 61, which can drive the tray 60 to smoothly protrude upward or downward out of the limiting hole 50.

[0039] As a further preferred embodiment, a support 52 is fixedly installed on the second boss 4. The supports 52 are spaced apart on the lower side of the middle of the bearing plate 5. The elastic element 51 is a top-compression spring, which connects the bearing plate 5 and the support 52. The top-compression spring ensures the reliable reset of the bearing plate 5 when released. Specifically, the support 52 is a U-shaped support with a central channel. The second connecting rod 62 is rotatably mounted in the central channel of the support 52. The central channel of the U-shaped support provides sufficient assembly space for the second connecting rod 62.

[0040] In this embodiment, the upper surface of the support plate 5 is provided with a guide groove 53 extending radially along the main shaft 2. The guide groove 53 is used to guide and cooperate with the culture dish. When the support plate 5 is pressed, the guide groove 53 allows the culture dish to slide smoothly downwards and be moved out. Specifically, the support plate 5 includes a first section and a second section. The first section is hinged to the first boss 3, and a limiting hole 50 is opened in the first section. The second section is fixedly connected to the first section and extends obliquely downwards with a large inclination angle, ensuring smoother movement.

[0041] The first boss 3 has multiple first grooves 30, which are circumferentially spaced. One end of each of the multiple bearing plates 5 is hinged in the first groove 30. The second boss 4 has multiple second grooves 40, which are arranged radially opposite to the first grooves 30 along the main shaft 2. The connecting rod structure 6 and the support 52 are both located in the second grooves 40.

[0042] The tissue culture chamber 1 is hinged with a door 16. Opening the door 16 allows for the removal or placement of petri dishes, while closing the door 16 ensures a constant internal temperature. The plant seedling tissue culture device also includes a ring lamp 11, which is mounted on the outside of the main shaft 2. The ring lamp 11 and the support plate 5 are arranged vertically at intervals. A lamp holder 12 is fixedly connected between the ring lamp 11 and the tissue culture chamber 1. The ring lamp 11 provides uniform illumination to the petri dishes on the support plate 5, ensuring uniform light exposure for the plant seedlings.

[0043] In addition, the plant seedling tissue culture device also includes a drive motor 13, which is fixedly installed on the tissue culture box 1. The motor shaft of the drive motor 13 is connected to a first gear 14 for anti-rotation, and the end of the main shaft 2 is connected to a second gear 15 for anti-rotation. The first gear 14 and the second gear 15 mesh with each other. The design of the drive motor 13 and the gear set can drive the main shaft 2, the support plate 5, and the culture dish to rotate smoothly, with a high degree of automation and more stable operation under rotating light.

[0044] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
