Description

Technical Field

[0001] The utility model relates to the technical field of pinellia tissue culture, in particular to a shaking table for pinellia tissue culture and rapid propagation. Background Art

[0002] Pinellia ternata, a perennial herbaceous plant belonging to the Araceae family, is an important Chinese medicinal herb. In nature, Pinellia ternata primarily reproduces via bulbils that grow beneath the petioles. Due to the difficulty in collecting these bulbils, widespread cultivation is prohibited. Consequently, the only source of Pinellia ternata is from the wild, which is scattered, time-consuming, and increasingly scarce, often in short supply on the market. Tissue culture has been used to rapidly propagate Pinellia ternata, significantly increasing its reproduction coefficient and becoming an important method for large-scale production.

[0003] When the tissue of Pinellia ternata grows in a liquid culture medium, a shaker is generally used to shake the liquid culture medium. On the one hand, this can improve the oxygen supply in the culture medium, thereby greatly accelerating the growth of the Pinellia ternata tissue culture seedlings. On the other hand, shaking can effectively prevent the cells from being suspended in the culture medium for a long time, which seriously affects the production of cells and thus leads to problems such as seriously affecting the speed and quality of Pinellia ternata tissue culture breeding.

[0004] The stainless steel universal clamps used to fix culture dishes in existing shakers are mostly one-piece structures and cannot be adjusted. During the process of Pinellia tissue culture, culture dishes of different diameters and heights may be used, and the one-piece stainless steel universal clamps cannot meet the positioning operations of culture dishes of various diameters and heights, which limits the use of the shaker and urgently needs improvement. Utility Model Content

[0005] The utility model aims to provide a shaking table for rapid propagation of pinellia ternata tissue culture, which can adapt to the fixation of culture dishes with different diameters and heights and has strong adaptability and good versatility.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A shaker for rapid tissue culture and propagation of Pinellia ternata comprises a shaker body and a multi-layer rotary support plate arranged on the shaker body. The top of each rotary support plate is provided with multiple culture dish fixing mechanisms that can adapt to different diameters and heights. Each rotary support plate is longitudinally slidably engaged with a guide plate on the shaker body. The bottom of each rotary support plate is provided with a height adjustment mechanism for driving the rotary support plate to slide longitudinally along the guide plate for height adjustment. The bottom of each guide plate is fixed on a rotary drive plate, and the rotary drive plate is connected to the rotary drive mechanism in the shaker body.

[0008] By adopting the above-mentioned technical scheme, the culture dish fixing mechanism is used to fix the Pinellia tissue culture dish on the rotary tray, and the rotary tray performs horizontal rotary motion under the drive of the rotary drive mechanism, thereby driving the liquid culture medium in each Pinellia tissue culture dish to oscillate, thereby achieving the effect of accelerating the growth of Pinellia tissue culture seedlings. The culture dish fixing mechanism can adapt to the fixation of culture dishes of different diameters and heights, making the shaker more adaptable and more versatile. The height adjustment mechanism is used to adjust the height of each rotary tray, so that the height difference between adjacent rotary trays matches the height of the Pinellia tissue culture dish fixed on the adjacent rotary trays, which is beneficial to ensuring that the Pinellia tissue culture dishes on each rotary tray have sufficient oxygen and light, and is beneficial to ensuring the growth quality of the Pinellia tissue culture seedlings.

[0009] The utility model is further configured as follows: the culture dish fixing mechanism includes a base plate fixedly connected to the revolving support plate, and upwardly bent clamping parts are respectively provided on the four sides of the base plate, and each of the clamping parts is located on the same circumference, and the top end of each clamping part is bent in a direction away from the center of the base plate and then bent perpendicularly to the direction of the base plate.

[0010] By adopting the above technical solution, the bottom plate is used to support the bottom of the Pinellia tissue culture dish, and the clamping parts around the bottom plate are used to clamp and limit the side walls of the Pinellia tissue culture dish, so that the Pinellia tissue culture dish and the rotary support plate are relatively fixed, ensuring that the Pinellia tissue culture dish can perform horizontal rotary motion back and forth with the rotary support plate, thereby driving the liquid culture medium in each Pinellia tissue culture dish to vibrate, thereby achieving the effect of accelerating the growth of Pinellia tissue culture seedlings.

[0011] The present invention is further configured such that the end portion of each clamping portion that is bent perpendicularly to the bottom plate is connected to a clamping position adjustment mechanism.

[0012] By adopting the above technical solution, the clamping position adjustment mechanism adjusts the clamping height of each clamping part by adjusting the bending position of each clamping part, so that each clamping part can adapt to the clamping and fixing operation of Pinellia tissue culture dishes of different heights, effectively solving the problem that the existing one-piece stainless steel universal clamp cannot meet the positioning operation of culture dishes of various diameters and heights, and greatly improving the adaptability and versatility of the shaker.

[0013] The utility model is further configured as follows: the clamping position adjustment mechanism includes a rack 1, the rack 1 is longitudinally slidably matched with the rotary support plate, the top of the rack 1 is fixedly connected to the clamping portion at one end bent perpendicular to the direction of the base plate, the rack 1 is meshed with a gear 1, and the gear 1 in each of the clamping height adjustment mechanisms is meshed with a rack 2, the rack 2 is rotatably connected to the adjusting screw, and the adjusting screw is threadedly connected to the rotary support plate.

[0014] By adopting the above technical solution, when the clamping height of the clamping part needs to be adjusted, the adjusting screw is rotated. When the adjusting screw rotates, it will move axially upward or downward relative to the rotary support plate threadedly connected to it. When the adjusting screw moves axially upward or downward, it will drive the rack 2 connected to it to move upward or downward synchronously. When the rack 2 moves upward or downward, it drives the gear 1 meshing with it to rotate forward or reverse. When the gear 1 rotates forward or reverse, it drives the rack 1 meshing with it to move downward or upward. When the rack 1 moves downward or upward, it pulls the end connected to the clamping part downward or upward, so that the height of the bending position of the clamping part is reduced or increased, thereby reducing or increasing the clamping height of the clamping part. Therefore, the adjustment operation of the clamping height of the clamping part is realized, and the adjustment process is simple and easy to operate.

[0015] The present invention is further configured as follows: each of the clamping parts is integrally formed with the bottom plate, and both are made of elastic metal plates.

[0016] By adopting the above technical solution, the elastic metal plate has low manufacturing cost and is easy to process. By utilizing the elastic characteristics of the elastic metal, a good clamping effect can be achieved. During the clamping process, it can not only adapt to the clamping operation of Pinellia tissue culture dishes of different diameters, but also does not require additional power during clamping, the clamping force is stable, and it is not easy to cause damage to the Pinellia tissue culture dish.

[0017] The present invention is further configured as follows: each of the clamping portions gradually moves toward one side of the center of the bottom plate from bottom to top.

[0018] By adopting the above technical solution, after each of the clamping parts gradually moves toward one side of the center of the bottom plate from bottom to top, a conical accommodating cavity is formed on the inner side of each clamping part. When the Pinellia tissue culture dish is placed on the bottom plate, the clamping position of the clamping part is located at the upper end of each Pinellia tissue culture dish, which can effectively reduce the risk of the Pinellia tissue culture dish escaping from the conical accommodating cavity formed on the inner side of each clamping part during the reciprocating horizontal rotation motion of the rotating support plate, thereby greatly improving the reliability of the device.

[0019] The present invention is further configured as follows: the clamping parts are connected by a connecting spring, and the connecting spring is sleeved on the outer wall of the upper end of each clamping part.

[0020] By adopting the above technical solution, the connecting spring is used to further apply a force to the upper ends of each clamping part to move closer to each other. The elastic force of the connecting spring can drive the upper ends of each clamping part to further clamp the Pinellia tissue culture dish, effectively strengthening the force of the clamping part that relies solely on its own elastic force to clamp, playing a double insurance role and effectively improving the reliability of clamping.

[0021] The utility model is further configured as follows: the height adjustment mechanism includes a cylinder for supporting the rotating support plate, the bottom of the cylinder is fixed to the upper surface of the lower rotating support plate or the rotating drive plate, and the telescopic shaft of the cylinder is fixed to the bottom surface of the upper rotating support plate.

[0022] By adopting the above-mentioned technical solution, when it is necessary to adjust the height of each rotating pallet so that the height difference between adjacent rotating pallets matches the height of the Pinellia tissue culture dish fixed on the adjacent rotating pallets, each cylinder used to support the rotating pallet is started, so that the telescopic shaft of each cylinder used to support the rotating pallet is extended or retracted, thereby pushing each rotating pallet to slide longitudinally along the guide plate, thereby realizing the height adjustment operation of each rotating pallet, so that the height difference between adjacent rotating pallets matches the height of the Pinellia tissue culture dish fixed on the adjacent rotating pallets, so as to meet the height requirements of Pinellia tissue culture dishes of different heights. The adjustment process is simple and easy to operate.

[0023] The present invention is further configured as follows: the rotary drive mechanism includes a drive motor fixed to the bottom of the rocking table body, the output shaft of the drive motor is fixedly connected to the center of the drive turntable, one side of the rotation center of the drive turntable is connected to the rotary drive plate through a connecting shaft, one end of the connecting shaft is rotatably connected to one side of the rotation center of the drive turntable, and the other end of the connecting shaft is rotatably connected to the rotary drive plate.

[0024] By adopting the above technical solution, when it is necessary to drive each rotary support plate to perform horizontal rotary motion, the drive motor is controlled to start. After the drive motor is started, it drives the drive turntable connected to the output shaft to rotate. When the drive turntable rotates, it drives the rotary drive plate connected to the child labor connecting shaft on one side of its center to perform circular motion. When the rotary drive plate performs circular motion, it drives the rotary support plates installed above the rotary drive plate to perform horizontal rotary motion, thereby achieving the effect of driving the liquid culture medium in each Pinellia tissue culture dish to vibrate, thereby accelerating the growth of Pinellia tissue culture seedlings.

[0025] The beneficial effects of the utility model are:

[0027] 2. The culture dish fixing mechanism of the present invention supports the bottom of the pinellia tissue culture dish through the bottom plate, and clamps and limits the side walls of the pinellia tissue culture dish through the clamping parts around the bottom plate, so that the pinellia tissue culture dish and the rotary support plate are relatively fixed, ensuring that the pinellia tissue culture dish can make a horizontal rotary motion back and forth with the rotary support plate, thereby driving the liquid culture medium in each pinellia tissue culture dish to vibrate, thereby achieving the effect of accelerating the growth of the pinellia tissue culture seedlings. The clamping part and the bottom plate are made of an integrally formed elastic metal plate, with low manufacturing cost and convenient processing. The elastic characteristics of the elastic metal are utilized to achieve a good clamping effect. During the clamping process, it can not only adapt to the clamping operation of pinellia tissue culture dishes of different diameters, but also no additional power is required during clamping, the clamping force is stable, and it is not easy to cause damage to the pinellia tissue culture dish.
