[0002] With the continuous improvement of living conditions, people generally pay more and more attention to enhancing their physical fitness and maintaining health by consuming medicinal materials with nourishing effects through diet. Due to the huge population, the demand for medicinal plants has increased sharply. Moreover, cultivating medicinal plants by traditional methods not only requires a large amount of land, a long growth cycle, but also suitable climate. Any inappropriate condition will limit and reduce the yield of medicinal plants.

[0003] Therefore, scientific and technological personnel have developed a method and a culture device for large-scale cultivation using isolated tissues or cells of plants. By separating the organs of plants: roots, stems, leaves, etc., and then placing them in a culture medium containing nutrients for cultivation, while providing other environmental conditions suitable for growth, such as temperature, light, etc., callus, adventitious buds, and adventitious roots are induced from the organs of the plants. Finally, using these callus, adventitious buds, and adventitious roots as seeds for cultivating plants, and placing them in a culture device for cultivation.

[0004] In the prior art, a variety of culture tanks for cultivating adventitious roots have been designed and applied to the cultivation of adventitious roots of high-value medicinal materials such as ginseng and pseudo-ginseng. To control the length of adventitious roots and prevent them from tangling into a mass, the adventitious roots need to be frequently trimmed. Usually, a rotating shaft with a blade fixed at the end is inserted into the tank, and then an electric motor is connected to the rotating shaft to drive it to rotate, so as to cut the adventitious roots by the high-speed rotation of the blade.

[0005] In the actual application process of this cutting structure, the following problems often occur in the culture tank: the adventitious roots in the area near the cutting blade are cut into fragments, while the adventitious roots in other areas rotate around but cannot approach the cutting blade.

Detailed implementation manners

[0031] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0032] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by terms such as "inner" and "outer" is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0033] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "contacted", and "communicated" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] In the present invention, plant tissues include callus, adventitious buds, adventitious roots, etc. induced from tissues or cells isolated from plants in vitro.

[0035] A culture device for large-scale cultivation of adventitious roots is provided with at least two plant tissue culture tanks with different volumes.

[0036] Taking a culture device with two plant tissue culture tanks as an example. For the convenience of distinction, the plant tissue culture tank with a smaller volume is called an adventitious root seed tank, and the plant tissue culture tank with a larger volume is called an adventitious root fermentation tank.

[0037] Among them, the tank body of the plant tissue culture tank is entirely made of stainless steel material. The ratio of the height to the diameter of the tank body is 1:1. The volume of the adventitious root seed tank is 200L, and the volumes of the adventitious root fermentation tanks are 1000L and 1500L.

[0038] The plant tissue culture tank is filled with a culture solution. The growth rate of adventitious roots in the plant tissue culture tank is much faster than that of primary roots. After a period of growth, a large number of adventitious roots will entangle with each other and even form clusters, which will seriously affect the production speed and quality of adventitious roots. Therefore, it is necessary to regularly trim the adventitious roots to accurately control the length of adventitious roots, ensure the growth rate, and improve the yield and quality of adventitious roots.

[0039] Example 1

[0040] As Figure 1 and Figure 2 shown, in an embodiment of the present invention, a cutting structure with a deflector 35 is introduced.

[0041] The cutting structure includes a shearing part 32 provided with a first blade 323 and a second blade 324. Among them, the first blade 323 and the second blade 324 are arranged in contact with each other and are connected in series by a pin shaft 321 perpendicular to the contact surface. The first blade 323 and the second blade 324 can both rotate freely around the pin shaft 321, and the relative side edges of the two blades form an opening and closing incision, which can be used to cut adventitious roots.

[0042] Another preferred connection method: The first blade 323 is fixedly connected to the pin shaft 321. The second blade 324 can rotate around the pin shaft 321.

[0043] Specifically, when the cutting structure is opened, the first blade 323 and / or the second blade 324 rotate around the pin shaft 321 to form a circular surface centered on the pin shaft 321 and perpendicular to the pin shaft 321. In order to avoid the problem of repeated cutting caused by the cut adventitious roots circulating in a small area near the blade, the cutting structure is also provided with a deflector 35. The deflector 35 is made of a thin-walled material and is sleeved on the outer periphery of the shearing part 32.

[0044] Particularly, the deflector 35 is also provided with a parallel inlet 351 and an outlet 352. And the inlet 351 and the outlet 352 are parallel to the circular surface formed when the blade rotates.

[0045] In this embodiment, by providing a guide cover 35 on the periphery of the cutting portion 32, the adventitious roots can be promoted to flow from one side of the cutting portion 32 to the other side, thereby increasing the circulation flow speed of the adventitious roots. At the same time, the circulation flow area of ​​the nutrient solution in the plant tissue culture tank can be increased and promoted, ensuring that the severed adventitious roots quickly flow from the cutting portion 32 to other areas, avoiding the adventitious roots from circulating in a small range near the cutting portion 32, thereby reducing the ratio of repeated cutting of the adventitious roots, preventing the problem of uneven length of the adventitious roots, and effectively improving the quality of the adventitious roots in the culture tank.

[0046] like Figure 2 As shown, in another embodiment of the present invention, a cutting structure provided with a spacer 31 is introduced. The cutting structure is further provided with a spacer 31. One side of the spacer 31 is connected to the shearing portion 32, and the other side is connected to the power portion 34, for separating the shearing portion 32 from the power portion 34.

[0047] The tank wall 11 of the plant tissue culture tank is provided with a circular mounting hole, and the outer peripheral surface of the spacer 31 is set to be cylindrical and has the same diameter as the mounting hole. The spacer 31 is detachably embedded in the mounting hole on the tank wall 11.

[0048] The shearing part 32 is installed in the spacer 31 on the side facing the tank cavity 90, and the power part 34 is installed on the side facing the outside of the plant tissue culture tank on the spacer 31. The shearing part 32 can be directly inserted into the installation hole by making the cross section of the spacer 31 larger than the cross section of the shearing part 32.

[0049] In particular, the spacer 31 penetrates into the air deflector 35 from the outlet 352 of the air deflector 35 and is connected to the shearing portion 32. Accordingly, the inlet 351 of the air deflector 35 is located on the side of the shearing portion 32 away from the spacer 31 in the axial direction of the shearing portion 32.

[0050] In this embodiment, the guide cover 35 is sleeved on the outside of the spacer sleeve 31. The guide cover 35 can be easily and quickly set on the plant tissue culture tank by disassembling the spacer sleeve 31, so that the guide cover 35 is easy to repair and replace.

[0051] like Figure 2 As shown, in another embodiment of the present invention, a spacer 31 for a plant tissue culture tank is introduced. The spacer 31 includes a cylindrical protrusion 311. The flow guide 35 is provided with a cylindrical through hole and is sleeved on the outer circumference of the protrusion 311. There is a gap between the through hole surface of the flow guide 35 and the outer surface of the protrusion 311. The gap forms an annular channel.

[0052] In another embodiment, the spacer 31 is further provided with a flange 312 extending outward from the end surface edge of the boss 311. The flange 312 is in a circular ring shape. The air guide cover 35 is connected to the flange 312.

[0053] Preferably, the air deflector 35 is connected to the outer ring edge of the flange 312 .

[0054] In another embodiment, the deflector 35 is configured as a cylindrical thin-walled tube. The deflector 35 is also provided with a cavity that passes through both ends along the central axis direction. The inlet 351 and the outlet 352 communicate with the cavity and are respectively located at both ends of the thin-walled tube.

[0055] In another embodiment, a circulation port 353 is further provided on the side wall of the air guide 35. When the air guide 35 is sleeved on the cutting structure, along the axis direction of the cutting structure, one end of the circulation port 353 is aligned with the shearing portion 32 and the other end is close to the outlet 352.

[0056] In this embodiment, a flow guide cover 35 is provided on the periphery of the shearing portion 32, thereby increasing the circulation area of ​​the nutrient solution in the plant tissue culture tank, promoting the adventitious roots to circulate over a large range in the tank cavity 90, and preventing the adventitious roots in the vicinity of the shearing portion 32 from being affected by the shearing portion 32 and circulating only in a small range, thereby ensuring that the plant tissue culture tank is in a good circulation state, thereby ensuring that the adventitious roots can be trimmed.

[0057] like Figure 2 As shown, in another embodiment of the present invention, a transmission part 33 is introduced which is sleeved in the air deflector 35. The cutting structure is further provided with a transmission part 33 between the shearing part 32 and the power part 34. The transmission part 33 is used to pull the shearing part 32. One end of the transmission part 33 is connected to the shearing part 32, and the other end is rotatably sleeved on the spacer 31 and is located in the cavity of the air deflector 35.

[0058] Specifically, the transmission part 33 is cylindrical and sleeved on the spacer 31. The inner cylinder surface of the transmission part 33 and the outer peripheral surface of the spacer 31 can be set to be slidably connected, or can be set to be rotatably connected and connected together through a bearing.

[0059] In particular, the transmission part 33 can rotate around the spacer 31. The transmission part 33 is connected to the second blade 324 and rotates synchronously, and the power part 34 drives the shearing part 32 to cut the adventitious roots through the transmission part 33.

[0060] In another embodiment, in order to avoid interference when the transmission part 33 is simultaneously sleeved with the shearing part 32 and the spacer sleeve 31 , reduce the fitting tolerance, and lower the difficulty of assembly, the transmission part 33 is configured as a structure composed of a discharge section 331 and a drive section 332 .

[0061] Among them, the discharging section 331 can be set as a thin rod shape. And the discharging section 331 has a through hole penetrating both ends along the central axis. The driving section 332 is a cylindrical shape with one end open and the other end closed. The discharging section 331 coincides with the driving section 332 in the central axis and is connected to the closed end face of the driving section 332. At this time, the flow guide cover 35 is sleeved outside the transmission part 33. An annular cavity is formed between the discharging section 331 and the flow guide cover 35, which can be used to temporarily store the adventitious roots after cutting.

[0062] Further, the shearing part 32 includes a pin shaft 321, a first blade 323 fixed to the pin shaft 321, and a second blade 324 rotatable around the pin shaft 321. The second blade 324 is provided with two blade ends 326. The discharging section 331 is sleeved on the pin shaft 321 and is connected to the second blade 324 at its end. The blade ends 326 are suspended in the cavity between the discharging section 331 and the flow guide cover 35, and the blade ends 326 are provided with spiral surfaces.

[0063] Preferably, the arc length of the circulation port 353 in the circumferential direction of the flow guide cover 35 corresponds to the included angle between the blade ends 326 of the first blade 323. Thus, the interval between the circulation port 353 and the blade ends 326 of the first blade 323 is aligned, eliminating the resistance of the adventitious root circulation.

[0064] Another preferred solution is that the discharging section 331 is set as a cylindrical shape. And, the diameter of the outer peripheral surface of the discharging section 331 is the same as the diameter of the inner surface of the driving section 332, and it can be embedded in the driving section 332 for connection.

[0065] In another embodiment of the present invention, a plant tissue culture tank provided with the above cutting structure is introduced.

[0066] In this plant tissue culture tank, a flow guide cover 35 for guiding the liquid flow is further provided on the cutting structure. By setting the flow guide cover 35, it can better promote the circulation of adventitious roots in the cavity 90 of the tank body, increase and promote the circulation flow area of the nutrient solution in the plant tissue culture tank, avoid the cutting structure from repeatedly cutting the adventitious roots that have been cut, ensure that the lengths of the adventitious roots are uniform, better maintain the growth cycle of the adventitious roots, improve the quality of the adventitious roots and the yield of the adventitious roots.

[0067] Embodiment 2

[0068] As Figure 2 shown, some cutting structures of the plant tissue culture tank are introduced in this embodiment. The cutting structure is detachably connected to the tank wall 11 of the plant tissue culture tank.

[0069] Specifically, the cutting structure includes a cutting part 32 and a power part 34. The power part 34 can drive the cutting part 32 to cut adventitious roots. The power part 34 is not directly connected to the cutting part 32. The cutting part 32 is arranged in the cavity 90 of the tank body of the plant tissue culture tank, while the power part 34 is arranged outside the plant tissue culture tank. There is a tank wall 11 of the plant tissue culture tank between the power part 34 and the cutting part 32.

[0070] Particularly, the plant tissue culture tank is also provided with a spacer sleeve 31. A circular mounting hole is formed in the tank wall 11 of the plant tissue culture tank. The outer peripheral surface of the spacer sleeve 31 is cylindrical and has the same diameter as that of the mounting hole. The spacer sleeve 31 is detachably embedded in the mounting hole on the tank wall 11.

[0071] One side of the spacer sleeve 31 is connected to the cutting part 32, and the other side is connected to the power part 34, which is used to separate the cutting part 32 and the power part 34 inside and outside the plant tissue culture tank. The cutting part 32 is installed on one side of the spacer sleeve 31 facing the cavity 90 of the tank body, and the power part 34 is installed on one side of the spacer sleeve 31 facing the outside of the plant tissue culture tank. Making the cross-section of the spacer sleeve 31 larger than that of the cutting part 32 allows the cutting part 32 to be directly inserted from the mounting hole, so that the cutting structure can be simply and quickly arranged on the plant tissue culture tank.

[0072] The spacer sleeve 31 has various styles. In some embodiments of the present invention, the spacer sleeve 31 is annular and formed with an annular groove. When the spacer sleeve 31 is annular, the middle part of the spacer sleeve 31 is a thin wall plate, and an annular groove formed by recessing towards one side of the plate surface is provided on the outer circumference of the thin wall plate.

[0073] In other embodiments, the spacer sleeve 31 is cylindrical and formed with a cylindrical groove.

[0074] The cavity opening of the spacer sleeve 31 is always located at the end face of the spacer sleeve 31. In some embodiments, the spacer sleeve 31 and the tank wall 11 are integral and are formed by the tank wall 11 recessing into the cavity of the tank body. At this time, the groove opening of the spacer sleeve 31 is formed on the surface of the tank body.

[0075] In other embodiments, the spacer sleeve 31 is an independent part and can be separated from the tank wall 11. The spacer sleeve 31 can be detachably installed on the tank wall 11 through fasteners, or can be fixed on the tank wall 11 by means of bonding or welding.

[0076] In this embodiment, a cutting structure capable of cutting adventitious roots is provided in the plant tissue culture tank, and a spacer sleeve 31 is also provided between the shearing portion 32 and the power portion 34, so that the cutting structure is dispersedly installed inside and outside the tank wall 11 of the plant tissue culture tank. In this way, the length of the adventitious roots can be controlled by the cutting structure to maintain and promote the cultivation efficiency of the adventitious roots, and microorganisms or impurities can be prevented from entering the plant tissue culture tank through the cutting structure, thereby improving the sealing of the plant tissue culture tank.

[0077] like Figure 2 As shown, in another embodiment of the present invention, a spacer sleeve 31 of a cutting structure is introduced. The spacer sleeve 31 can enable the power part 34 to better attract and drive the shearing part 32 from one side of the spacer sleeve 31 to perform the cutting action, which simplifies the structure of mutual attraction between the shearing part 32 and the power part 34 and increases the attraction of the power part 34 to the shearing part 32.

[0078] Specifically, the spacer 31 protrudes from the surface of the tank wall 11 toward the tank body cavity 90 along the vertical direction of the tank wall 11 of the plant tissue culture tank. From the outside of the tank wall 11 of the plant tissue culture tank, corresponding to the position where the spacer 31 protrudes toward the tank body cavity 90, the spacer 31 forms a groove on the other side.

[0079] In particular, the shearing portion 32 is connected to the outer convex surface of the spacer 31, and the power portion 34 is installed at the groove. Preferably, the shearing portion 32 is provided with a component that is sleeved on the outer periphery of the spacer 31 and can rotate relative to the spacer 31, and the power portion 34 attracts and drives the component from the other side of the spacer 31 through the spacer 31, thereby driving the shearing portion 32 to cut the adventitious roots.

[0080] In this embodiment, by optimizing the shape of the spacer sleeve 31 and making the spacer sleeve 31 protrude into the tank cavity 90, the attraction and driving effect of the power part 34 on the shearing part 32 can be enhanced, ensuring that the cutting structure can better shear the adventitious roots and avoid the entanglement and clumping of the adventitious roots, thereby promoting faster growth of the adventitious roots.

[0081] like Figure 2 As shown, in another embodiment of the present invention, another spacer 31 with a cutting structure is introduced. Different from the spacer 31 in the previous embodiment, the outer circumference of the spacer 31 is provided with an annular groove recessed along the central axis direction thereof, and the middle part of the spacer 31 is located between the groove bottom and the groove top in the central axis direction of the annular groove.

[0082] Preferably, the middle portion of the spacer 31 is flush with the tank top, that is, the middle portion of the spacer 31 is flush with the surface of the tank wall 11 of the plant tissue culture tank.

[0083] Specifically, when the spacer sleeve 31 is arranged on the plant tissue culture tank, the annular groove of the spacer sleeve 31 extends from the surface of the tank wall 11 of the plant tissue culture tank along the perpendicular direction of the tank wall 11 towards the cavity 90 of the tank body, and the notch of the annular groove is located on the surface of the tank wall 11 of the plant tissue culture tank, so that the spacer sleeve 31 forms an annular structure with an annular groove.

[0084] Preferably, the middle part of the spacer sleeve 31 protrudes towards the cavity 90 of the tank body to form a cylindrical structure with a cylindrical groove. In this embodiment, by optimizing the shape of the spacer sleeve 31, the spacer sleeve 31 protrudes into the cavity 90 of the tank body, which can enhance the attraction and driving effect of the power part 34 on the shearing part 32, ensure that the cutting structure better shears the adventitious roots, avoid the entanglement and agglomeration of the adventitious roots, and thus promote the faster growth of the adventitious roots.

[0085] As Figure 2 shown, in another embodiment of the present invention, a spacer sleeve 31 detachably installed on the plant tissue culture tank is introduced. An installation hole is opened on the tank wall 11. If the spacer sleeve 31 is annular, it is fixed on the installation hole in the way that its annular groove is embedded into the cavity 90 of the tank body; if the spacer sleeve 31 is barrel-shaped, it is fixed on the installation hole in the way that its barrel bottom is embedded into the cavity 90 of the tank body.

[0086] Specifically, an installation hole is opened on the tank wall 11 of the plant tissue culture tank, and the outer peripheral surface of the spacer sleeve 31 is set to be cylindrical and has the same diameter as the installation hole. The spacer sleeve 31 is detachably embedded in the installation hole on the tank wall 11.

[0087] In this embodiment, one side of the spacer sleeve 31 is connected to the shearing part 32 and the other side is connected to the power part 34, separating the shearing part 32 and the power part 34 inside and outside the plant tissue culture tank. The shearing part 32 is installed in the cavity 90 of the tank body, and the power part 34 is installed outside the plant tissue culture tank. The shearing part 32 can be directly put into the cavity 90 of the tank body of the plant tissue culture tank from the installation hole, so that the cutting structure can be simply and quickly arranged on the plant tissue culture tank.

[0088] As Figure 1 shown, in another embodiment of the present invention, a plant tissue culture tank and the installation position of the spacer sleeve 31 are introduced.

[0089] The plant tissue culture tank is set in a rotary body shape, and its central axis is along the vertical direction. The tank wall 11 of the plant tissue culture tank at least includes a part that extends from top to bottom and gradually inclines towards the central axis of the plant tissue culture tank. This part forms an inverted cone.

[0090] Preferably, the tank wall 11 also includes a cylindrical portion parallel to the central axis. The cylindrical portion is connected to the inverted conical portion to form the plant tissue culture tank as a whole, and the inverted conical portion is located below and is set as the tank bottom 20 of the plant tissue culture tank. The spacer 31 is arranged on the inverted conical portion, that is, the spacer 31 is arranged on the tank bottom 20, so that the cutting structure is distributed on the tank bottom 20 of the plant tissue culture tank.

[0091] In this embodiment, the plant tissue culture tank is provided with an inverted conical tank bottom 20, which can reduce the pressure of the nutrient solution on the adventitious roots, which is conducive to the growth of the adventitious roots. In addition, the inverted conical tank bottom 20 can gather the adventitious roots suspended in the nutrient solution, so that the spacer 31 and the cutting structure are installed on the inverted conical tank bottom 20, ensuring that the cutting structure can shear the adventitious roots in a concentrated and efficient manner.

[0092] like Figure 3 As shown, in some other embodiments of the present invention, a shearing portion 32 of a cutting structure is introduced. The shearing portion 32 includes a first blade 323 and a second blade 324. The first blade 323 and the second blade 324 are arranged adjacent to each other and connected in series by a rotating shaft perpendicular to the adjacent surfaces. The first blade 323 and the second blade 324 can both rotate freely around the rotating shaft, and the opposite sides of the two blades form a continuously opening and closing incision, which can be used to shear adventitious roots.

[0093] Another preferred connection mode is that the first blade 323 is fixedly connected, and the second blade 324 rotates relative to the first blade 323 around the rotation axis.

[0094] More preferably, the first blade 323 is fixedly connected to the spacer 31, and the second blade 324 is sleeved with the spacer 31 and can rotate relative to the central axis of the spacer 31. At the same time, the power unit 34 is provided with a rotor that moves in a circular motion in the groove. A magnetic attraction member is installed on the rotor, which can attract the second blade 324 through the spacer 31.

[0095] In this embodiment, the shearing portion 32 is composed of two relatively rotatable blades, and the two blades form a continuously opening and closing incision, which shears the adventitious roots through the incision to make the incision of the adventitious roots flat, thereby avoiding dragging and tearing of the adventitious roots, improving the success rate of cutting the adventitious roots, avoiding necrosis of the adventitious roots after being cut, and improving the yield and quality of the adventitious roots.

[0096] like Figure 2 As shown, in another embodiment of the present invention, a cutting portion 32 capable of cutting adventitious roots of a fixed length is introduced.

[0097] The shearing part 32 at least includes two blade groups 322 arranged at intervals in the axial direction. The blade group 322 includes the first blade 323 and the second blade 324, and the sides of the two are in contact. The interval between adjacent blade groups 322 is between 10 mm and 15 mm.

[0098] Specifically, all the first blades 323 in the blade group 322 are parallel to each other and are fixed to the rotating shaft. All the second blades 324 are parallel to each other and are joined at the ends in their own length directions to form a frame covering the outside of the first blades 323. The second blades 324 rotate relative to the first blades 323 to form an opening and closing incision.

[0099] In this way, when the second blade 324 is driven to rotate relative to the first blade 323, the adjacent blade groups 322 simultaneously shear the adventitious roots entering the shearing part 32, so that the length of the cut adventitious roots is the same as the interval between the adjacent blade groups 322.

[0100] In this embodiment, multiple groups of blades are provided in the shearing part 32, and the blade groups 322 are arranged at a fixed interval, so that adventitious roots of the same length can be obtained by cutting the adventitious roots, enabling the adventitious roots in the plant tissue culture tank to have the same growth state, facilitating the regular adjustment of the nutrient content of the nutrient solution and the pruning of adventitious roots, promoting the circulation of the nutrient solution in the plant tissue culture tank, maintaining stable growth conditions, and improving the cultivation efficiency and the quality of adventitious roots.

[0101] As Figure 2 shown, in another embodiment of the present invention, a cutting structure of a plant tissue culture tank is introduced. A transmission part 33 is further provided between the shearing part 32 and the power part 34 of the cutting structure.

[0102] Specifically, the transmission part 33 is cylindrical and is sleeved on the spacer sleeve 31. The inner cylindrical surface of the transmission part 33 and the outer peripheral surface of the spacer sleeve 31 can be set to be slidably connected, or can be set to be rotatably connected and connected together through bearings. Particularly, the transmission part 33 can rotate around the spacer sleeve 31. The transmission part 33 is connected to the second blade 324 and rotates synchronously, and the power part 34 drives the shearing part 32 to cut adventitious roots through the transmission part 33.

[0103] As Figure 3 shown, in another embodiment of the present invention, a flow guide cover 35 of a cutting structure is introduced. A cutting structure is provided in the plant tissue culture tank. In order to better promote the circulation of adventitious roots in the cavity 90 of the tank body and avoid the cutting structure from repeatedly cutting a part of the adventitious roots, a flow guide cover 35 for guiding the liquid flow is further provided on the cutting structure.

[0104] Specifically, the flow guide cover 35 is a cylindrical thin-walled cylinder and is provided with a cavity penetrating through both ends along its central axis direction.

[0105] The flow guide cover 35 is sleeved on the outer periphery of the shearing part 32. One end of the flow guide cover 35 protrudes from the shearing part 32 and an inlet 351 is provided on this end face. The inlet 351 is parallel to the circular surface formed by the rotation of the second blade 324. The other end of the flow guide cover 35 extends towards the tank wall 11 and an outlet 352 is provided on this end face. The outlet 352 is sleeved on the outer periphery of the transmission part 33, so that the flow guide cover 35 at least partially covers the transmission part 33.

[0106] In this embodiment, by arranging the flow guide cover 35 on the outer periphery of the shearing part 32, the circulating flow area of the nutrient solution in the plant tissue culture tank is increased, promoting the large-range circulation of adventitious roots in the cavity 90 of the tank body, avoiding that the adventitious roots in the area near the shearing part 32 are only circulated in a small range under the influence of the shearing part 32, ensuring that the plant tissue culture tank is in a good circulating state, so as to ensure that all adventitious roots can be trimmed.

[0107] As Figure 1 shown, in another embodiment of the present invention, a plant tissue culture tank is introduced. This plant tissue culture tank is provided with any one of the cutting structures in the above embodiments. Using this plant tissue culture tank to cultivate adventitious roots promotes the circulating flow of the nutrient solution in the plant tissue culture tank, provides stable growth conditions for adventitious roots, and improves the cultivation efficiency and quality of adventitious roots.

[0108] Embodiment Three

[0109] As Figure 1 shown, in this embodiment, a plant tissue culture tank is introduced. The plant tissue culture tank is provided with a cutting structure having a shearing part 32 and a power part 34. The power part 34 can drive the shearing part 32 to cut adventitious roots. The power part 34 is not directly connected to the shearing part 32.

[0110] Specifically, the shearing part 32 is arranged in the cavity 90 of the tank body of the plant tissue culture tank for shearing adventitious roots. The power part 34 is arranged outside the tank body of the plant tissue culture tank. And, the central axis of the power part 34 coincides with the central axis of the shearing part 32.

[0111] A rotor capable of driving the shearing part 32 to rotate to open and close the incision by magnetic force through the tank wall 11 is arranged on the power part 34. Specifically, a magnetic attracting member made of magnetic material is fixedly arranged on the rotor. The magnetic attracting member can attract the shearing part 32 through the tank wall 11 of the plant tissue culture tank and rotate around the central axis of the power part 34 following the rotor.

[0112] In this embodiment, the power unit 34 is arranged to drive the shearing unit 32 magnetically, removing the traditional shaft connection structure. Thus, there is no need to set a sealing structure between the plant tissue culture tank and the power unit 34, which not only improves the sealing of the tank wall 11 of the plant tissue culture tank, but also can completely prevent the oil stain or microorganisms of the power unit 34 from entering the interior of the plant tissue culture tank body, ensuring that the nutrient solution in the plant tissue culture tank can maintain a sterile environment for a long time, providing a stable and reliable environment for the growth of adventitious roots, and thus greatly improving the yield and quality of adventitious roots within the same culture period.

[0113] As Figure 3 shown, in another embodiment of the present invention, a shearing unit 32 applicable to a plant tissue culture tank is introduced.

[0114] The shearing unit 32 includes a first blade 323 and a second blade 324. Among them, the first blade 323 and the second blade 324 are arranged in contact with each other and are connected in series by a rotating shaft perpendicular to the contact surface. Both the first blade 323 and the second blade 324 can rotate freely around the rotating shaft, and the opposite side edges of the two blades form an opening and closing incision, which can be used to shear adventitious roots.

[0115] Preferably, the shearing unit 32 includes a fixed first blade 323 and a second blade 324 that can rotate relative to the first blade 323 to form an incision.

[0116] The power unit 34 is provided with a magnetic attraction member that can rotate around its central axis. The central axis of the power unit 34 is arranged to coincide with the central axis of the second blade 324. The magnetic attraction member confines the second blade 324 through the tank wall 11 with a magnetic field and rotates together with it.

[0117] In this embodiment, the shearing unit 32 is arranged to be composed of two relatively rotatable blades, and an opening and closing incision is formed by the two blades. The adventitious roots are sheared through the incision to make the cut ends of the adventitious roots flush, avoiding dragging and tearing of the adventitious roots, improving the success rate of cutting the adventitious roots, preventing the adventitious roots from necrosis after being cut, and improving the yield and quality of the adventitious roots.

[0118] As Figure 3 shown, in another embodiment of the present invention, a power unit 34 is introduced. The power unit 34 is provided with a stator and a rotor that can be driven by the stator. The stator is fixed on the outer side surface of the tank wall 11. The rotor and the stator are sleeved and matched with each other, and there is a gap between the rotor and the stator. Introducing energy into the rotor can stimulate the acting force of the stator on the rotor, and the acting force generates a torque effect relative to the central axis, thereby driving the rotor to rotate indefinitely around the stator.

[0119] It can be understood that the energy includes a power source, high-pressure gas, high-pressure liquid, etc.

[0120] In this embodiment, the power unit 34 is composed of a stator and a rotor to form a structure that can provide torque, reducing the parts of the power unit 34, improving the functional conversion efficiency of the power unit 34, and also reducing the noise during the operation of the power unit 34.

[0121] Furthermore, in another embodiment of the present invention, an optimized structure of the power unit 34 is introduced. In this power unit 34, the rotor is arranged in a ring shape, and the stator is arranged as a cylinder with a diameter smaller than the diameter of the annular hole of the rotor. The rotor is sleeved on the outer periphery of the stator.

[0122] The magnetic attracting member is fixed on the end face of the rotor facing the tank wall 11. An iron block that is easily attracted is provided on the outer periphery of the second blade 324. The magnetic attracting member rotates around the normal line of the second blade 324 along the tank wall 11 and attracts the second blade 324 to rotate together.

[0123] In this embodiment, the rotor of the power unit 34 is optimized to a circular ring shape, enabling the stator to apply a force to the rotor evenly, which is beneficial to maintaining the stability during the rotation process, increasing the rotational speed of the rotor and the torque of the power unit 34.

[0124] Furthermore, in another embodiment of the present invention, an optimized structure of the power unit 34 is introduced. The power unit 34 further includes a stator and a rotor. The stator is arranged in a ring shape and is made of a strong magnetic material. A through hole that penetrates both ends along its central axis is provided in the middle of the stator.

[0125] The rotor is arranged in a long rod shape. The rotor is sleeved in the through hole of the stator and can rotate freely in the through hole of the stator. The magnetic attracting member is fixed at one end of the rotor facing the tank wall 11.

[0126] Preferably, a coil is wound around one end of the rotor, and the other end is connected to the magnetic attracting member. The magnetic attracting member is cylindrical. The second blade 324 is further provided with a cylindrical transmission part 33. One end of the transmission part 33 is connected to the second blade 324, and the other end is sleeved on the outer periphery of the magnetic attracting member.

[0127] In this embodiment, setting the rotor of the power unit 34 to a long rod shape can arrange more parts on the rotor. One end is used to receive the driving force of the stator, and the other end is used to approach or extend into the shearing part 32, so as to increase the acting force attracting the shearing part 32, and a transmission part 33 with a simple structure can also be utilized, which is beneficial to reducing the volume of the power unit 34.

[0128] Furthermore, in another embodiment of the present invention, an electrically drivable power unit 34 is introduced.

[0129] The power unit 34 includes a stator and a rotor. A plurality of coils are wound around the rotor. Passing electricity through the coils can generate magnetic poles on the rotor that rotate around its central axis.

[0130] Specifically, multiple coils are evenly distributed around the rotor, and only one of the coils is energized. Then, by switching the energization between the coils in a clockwise or counterclockwise order, magnetic poles that continuously change direction around the central axis of the rotor can be generated on the rotor.

[0131] The stator is made of a magnetic material and generates a magnetic field with stable magnetic poles. By energizing the rotor to generate rotating magnetic poles, the rotor is driven to rotate relative to the stator by the attraction and repulsion between the magnetic poles.

[0132] In this embodiment, coils are arranged on the rotor, and magnetic poles can be generated by energizing the rotor. Furthermore, based on the property that like magnetic poles repel each other and opposite magnetic poles attract each other, the energized coils are synchronously switched by the rotation of the rotor, so that the magnetic poles on the rotor are always inconsistent with the magnetic poles of the rotor, and thus continuously receive the torque exerted by the stator on the rotor, greatly improving the function conversion efficiency of the power unit 34.

[0133] Further preferably, in another embodiment of the present invention, a power unit 34 that can be driven by a high-pressure medium is introduced. The power unit 34 includes a stator and a rotor, and the high-pressure medium flows between the stator and the rotor and does work on the rotor, causing the rotor to rotate relative to the stator.

[0134] Specifically, the stator is provided with a passage for conveying the high-pressure medium and a number of chambers. The passage communicates with all the chambers and can convey the high-pressure medium between the chambers. At least a part of the rotor is located between the chambers and blocks the passage. When the high-pressure medium flows from the passage to the adjacent chamber, a force can be exerted on the rotor. Pushed by the high-pressure medium, the rotor rotates relative to the stator.

[0135] After the high-pressure medium pushes the stator, it flows from one chamber into another chamber and loses a part of its pressure. The pressure is converted into the kinetic energy of the rotor.

[0136] Preferably, the high-pressure medium includes high-pressure gas or high-pressure liquid.

[0137] In this embodiment, the power unit 34 is provided with a structure that can convert high-pressure potential energy into kinetic energy, so that it can be driven by high-pressure gas or high-pressure liquid, enabling the power unit 34 to be used in flammable and explosive environments, expanding the application range of the power unit 34.

[0138] Furthermore, in another embodiment of the present invention, a control method for a plant tissue culture tank provided with the above-mentioned power unit 34 is introduced. The control method controls the start and stop of the power unit 34 by judging whether the length value of the adventitious roots meets the set conditions, so as to trim the adventitious roots.

[0139] Specifically, a standard value L0 of adventitious roots growing in a plant tissue culture tank is preset. The length value L1 of the adventitious roots is detected every time interval t, and the magnitudes of L1 and L0 are compared. If L1 is greater than L0, the power unit 34 is controlled to start cutting the adventitious roots.

[0140] In this embodiment, by regularly detecting adventitious roots to cut and control the length of adventitious roots, the problem that adventitious roots are prone to entanglement and necrosis is solved. And by cutting adventitious roots, adventitious roots are induced to generate callus, so that adventitious roots always maintain a high growth rate, improving the yield of adventitious roots.

[0141] Furthermore, in another embodiment of the present invention, an optimized control method is introduced.

[0142] A standard value L0 of adventitious roots growing in a plant tissue culture tank is preset. Several adventitious root samples are collected from the tank body every time interval t to obtain the actual length of the adventitious root samples.

[0143] The control calculates the average value of the actual lengths to obtain the length value L1 of the adventitious roots. The magnitudes of L1 and L0 are compared. If L1 is greater than L0, the power unit 34 is controlled to start cutting the adventitious roots.

[0144] In this embodiment, by obtaining the average value of adventitious root lengths to control the cutting cycle of adventitious roots, the operating state of the plant tissue culture tank can be controlled more precisely, providing more stable production conditions for adventitious roots. And by cutting adventitious roots, adventitious roots are induced to generate callus, so that adventitious roots always maintain a high growth rate, improving the cultivation efficiency and quality of adventitious roots.

[0145] Embodiment Four

[0146] As Figure 2 shown, in an embodiment of the present invention, a shearing part 32 of a cutting structure is introduced.

[0147] The shearing part 32 includes a pin shaft 321, a first blade 323, and a second blade 324 attached to the first blade 323. The first blade 323 and the second blade 324 are connected in series by the pin shaft 321. The pin shaft 321 is perpendicular to the plane of the first blade 323 and the second blade 324.

[0148] In a connection method: the first blade 323 is fixed to the pin shaft 321. The second blade 324 can rotate relative to the first blade 323 with the pin shaft 321 as the central axis. The opposite side edges of the two blades form an opening and closing cut, which can be used to cut adventitious roots.

[0149] Specifically, as the second blade 324 rotates, the edges of the two blades change from a spaced state to an overlapping state, forming an opening and closing cut on the opposite side edges of the two blades.

[0150] In this embodiment, the cutting part 32 is provided with two blades that can rotate relative to each other, and the sides of the two blades are in contact with each other, so that the overlapping and staggered edges of the two blades form an opening and closing cut. The adventitious roots can be completely cut off by squeezing the adventitious roots through the cut, avoiding the problem that the adventitious roots are not cut off or even entangled with the cutting part 32, which may cause damage to the cutting structure. It can also ensure the smoothness of the cut of the adventitious roots, avoid necrosis of the adventitious roots after being cut, and is beneficial to improving the growth rate and quality of the adventitious roots.

[0151] As Figure 2 shown, in an embodiment of the present invention, a cutting part 32 capable of cutting adventitious roots of the same length is introduced.

[0152] The cutting part 32 includes a plurality of blade groups 322 connected in series on the pin shaft 321. The plurality of blade groups 322 are evenly distributed along the axial direction of the pin shaft 321 to form a multi-layer structure. Among them, each blade group 322 is composed of the first blade 323 and the second blade 324 in contact with each other in pairs.

[0153] Specifically, all the first blades 323 in the blade group 322 are parallel to each other and fixed to the rotating shaft. All the second blades 324 are parallel to each other and are connected at the ends in their own length directions to form a frame covering the outside of the first blade 323. The second blade 324 rotates relative to the first blade 323 to form an opening and closing cut.

[0154] In this way, when the second blade 324 is driven to rotate relative to the first blade 323, the adjacent blade groups 322 simultaneously cut the adventitious roots entering the cutting part 32, so that the length of the cut adventitious roots is the same as the interval between the adjacent blade groups 322.

[0155] In this embodiment, the cutting part 32 is provided with multiple groups of blades, and the blade groups 322 are arranged at a fixed interval, so that the adventitious roots can be cut to obtain adventitious roots of the same length, making the adventitious roots in the plant tissue culture tank have the same growth state, facilitating the regular adjustment of the nutrient content of the nutrient solution and pruning the adventitious roots, promoting the circulation of the nutrient solution in the plant tissue culture tank, maintaining stable growth conditions, and improving the cultivation efficiency and the quality of the adventitious roots.

[0156] As Figure 2 shown, in another embodiment of the present invention, a cutting part 32 provided with two blade groups 322 is introduced.

[0157] The two first blades 323 are sleeved on the pin shaft 321 at intervals and are parallel to each other. The two second blades 324 respectively abut against the outer sides of the first blades 323 away from the interval.

[0158] The two second blades 324 are arranged in parallel and are joined at the ends in their own length directions to form a frame structure. The second blade 324 can be embedded inside the first blade 323 or can be arranged to wrap around the outside of the first blade 323.

[0159] Preferably, the second blade 324 wraps around the outside of the first blade 323, that is, it adheres to the side of the first blade 323 that is spaced apart and facing away.

[0160] In this embodiment, the shearing part 32 is provided with two blade groups 322, and the second blades 324 are joined as a whole, and can be connected and simultaneously drive the two second blades 324 to rotate from either side of the shearing part 32, simplifying the structure of the shearing part 32, enabling the shearing part 32 to not only cut adventitious roots of the same length, but also keep the cut openings of the two blade groups 322 opening and closing synchronously, improving the efficiency of trimming adventitious roots.

[0161] As Figure 3 shown, in another embodiment of the present invention, a second blade 324 of the shearing part 32 is introduced. The second blade 324 includes a rotating end 325 and a blade end 326.

[0162] One end of the blade end 326 is connected to the rotating end 325, and the other end extends along the diameter direction of the rotating end 325 and is suspended on the outer circumference to form a cantilever shape.

[0163] The rotating end 325 is sleeved on the pin shaft 321. When the second blade 324 rotates relative to the first blade 323, the blade end 326 can rotate around the pin shaft 321 to form an opening and closing cut.

[0164] As Figure 3 shown, in another embodiment of the present invention, a shearing part 32 that can form a curved cut is introduced. The first blade 323 and the second blade 324 have the same structure and shape. That is, they are both composed of a rotating end 325 and a blade end 326.

[0165] Among them, the blade end 326 includes a closed side 327 for cutting and pressing and an unfolded side 328 opposite to the closed side 327. The closed side 327 and the unfolded side 328 extend radially from the rotating end 325 to the other end and gradually approach each other.

[0166] As Figure 3 shown, in another embodiment of the present invention, a shearing part 32 that can gather adventitious roots is introduced. The two ends of the closed side 327 are located on the same diameter line. And, the closed side 327 extends along an arc from the rotating end 325 to the other end. Finally, a notch that is recessed inward is formed on the closed side 327 of the blade end 326.

[0167] When the second blade 324 rotates relative to the first blade 323, the incision gradually closes from both ends of the closing side 327 towards the notch.

[0168] Furthermore, the second blade 324 includes a plurality of blade ends 326 uniformly distributed along the outer periphery of the rotating end 325. For example, three blade ends 326 are arranged at intervals of 120° on the outer periphery of the rotating end 325. Four blade ends 326 are arranged at intervals of 90° on the outer periphery of the rotating end 325.

[0169] Preferably, the second blade 324 is provided with two blade ends 326 symmetrically distributed with respect to the rotating end 325.

[0170] In particular, the unfolding side 328 extends from the rotating end 325 towards the outer periphery along an arc, and the closing side 327 also extends from the rotating end 325 towards the outer periphery along an arc. Moreover, the unfolding side 328 and the closing side 327 gradually converge at a point. The second blade 324 is in an S shape and is composed of two blade ends 326 connected to the rotating end 325 and arranged at an interval of 180°.

[0171] As Figure 3 shown, in another embodiment of the present invention, a shearing part 32 capable of promoting the cyclic flow of adventitious roots is introduced. The blade end 326 gradually bends upward along the circumferential direction from the closing side 327 to the unfolding side 328 to form a curved surface.

[0172] Preferably, the blade end 326 is arranged as a helical surface along the diameter direction of the rotating end 325.

[0173] In another embodiment, in order to better guide the cyclic flow of adventitious roots in the culture tank, the first blade 323 is arranged in a long strip shape. And the first blade 323 is provided with pointed corners inclined to its diameter at both ends. The side of the pointed corner opposite to the closing side 327 is concave towards the first blade 323.

[0174] As Figure 1 shown, in another embodiment of the present invention, a cutting structure for a plant tissue culture tank is introduced.

[0175] The plant tissue culture tank is arranged in a rotary body shape, and its central axis is along the vertical direction. The tank wall 11 of the plant tissue culture tank at least includes a part that extends from top to bottom and gradually inclines towards the central axis of the plant tissue culture tank. This part forms an inverted cone.

[0176] Preferably, the tank wall 11 further includes a cylindrical portion parallel to the central axis. The cylindrical portion is connected to the inverted conical portion to form the overall plant tissue culture tank, and the inverted conical portion is arranged below as the tank bottom 20 of the plant tissue culture tank. The cutting structure is arranged on the inverted conical portion, that is, the spacer sleeve 31 is arranged on the tank bottom 20.

[0177] In this embodiment, arranging the cutting structure on the tank bottom 20 can quickly cut the adventitious roots, make the cut ends of the adventitious roots in the plant tissue culture tank flat, have the same growth state, facilitate the regular trimming of the adventitious roots in the culture tank, promote the nutrient solution circulation in the plant tissue culture tank, maintain good growth conditions for the adventitious roots, and improve the cultivation efficiency and quality of the adventitious roots in the culture tank.

[0178] Embodiment Five

[0179] As Figure 2 shown, in an embodiment of the present invention, a cutting structure with a transmission part 33 is introduced. The cutting structure includes a power part 34 and a shearing part 32 rotatably connected to the pin shaft 321. The power part 34 and the shearing part 32 are not directly connected. The shearing part 32 is arranged in the cavity 90 of the tank body of the plant tissue culture tank, while the power part 34 is arranged outside the plant tissue culture tank. The power part 34 and the shearing part 32 are separated by the tank wall 11 of the plant tissue culture tank.

[0180] Particularly, the cutting structure further includes a transmission part 33 sleeved on the pin shaft 321. The pin shaft 321 is fixed inside the tank wall 11 of the plant tissue culture tank. One end of the transmission part 33 is connected to the shearing part 32, and the other end is arranged close to the power part 34. The power part 34 transmits torque to the transmission part 33 through magnetic force and can drive the transmission part 33 to rotate around the pin shaft 321.

[0181] In this embodiment, a transmission part 33 is added between the shearing part 32 and the power part 34. The transmission part 33 can greatly increase the distance for the power part 34 to drive the shearing part 32, optimize the layout of the shearing part 32 in the plant tissue culture tank, so that the shearing part 32 can be close to the area with the highest adventitious root density, thereby improving the efficiency of the cutting structure for cutting adventitious roots, reducing the opening time of the cutting structure, greatly improving the environment in the plant tissue culture tank, and being beneficial to promoting the improvement of the quality and yield of adventitious roots.

[0182] As Figure 2As shown, in one embodiment of the present invention, a transmission part 33 connected to the shearing part 32 is introduced. The shearing part 32 includes a first blade 323 and a second blade 324. Among them, the first blade 323 and the second blade 324 are arranged in contact with each other and are connected in series by a pin shaft 321 perpendicular to the contact surface. Both the first blade 323 and the second blade 324 can rotate freely around the pin shaft 321, and the opposite side edges of the two blades form an opening and closing incision, which can be used for shearing adventitious roots.

[0183] Another preferably connection method: The first blade 323 is fixedly connected to the pin shaft 321. The second blade 324 can rotate around the pin shaft 321. The transmission part 33 is in a cylindrical shape and is sleeved on the pin shaft 321. At the same time, the transmission part 33 is also connected to the second blade 324.

[0184] Furthermore, in another embodiment of the present invention, a transmission part 33 connected to the second blade 324 is introduced. The second blade 324 is connected to the inner circumferential surface of the transmission part 33 at the end in the length direction.

[0185] Specifically, the transmission part 33 is in a cylindrical shape, and a through hole penetrating both ends along its central axis is provided in the middle thereof. The second blade 324 is embedded and connected in the through hole of the transmission part 33. The second blade 324 is connected to the inner surface of the through hole with its two ends, and the length direction of the second blade 324 is parallel to the diameter of the through hole.

[0186] In this embodiment, the shearing part 32 is embedded in the through hole of the transmission part 33. The transmission part 33 is connected to the second blade 324 and is isolated from the first blade 323, so that it can drive the second blade 324 to rotate relative to the first blade 323, and can push the adventitious roots to circulate along the axis direction of the transmission part 33, thereby avoiding repeated cutting of the adventitious roots, being beneficial to ensuring the length of the adventitious roots, and improving the quality of the adventitious roots.

[0187] Such as Figure 2 As shown, in another embodiment of the present invention, a cutting structure is introduced. The cutting structure includes a plurality of blade groups 322 connected in series on the pin shaft 321. The plurality of blade groups 322 are equally spaced along the axis direction of the pin shaft 321 to form a multi-layer structure. Among them, each blade group 322 is composed of the first blade 323 and the second blade 324 in contact with each other in pairs.

[0188] Preferably, the cutting structure is provided with two blade groups 322. The two first blades 323 are sleeved on the pin shaft 321 in parallel and at intervals, and the two second blades 324 are arranged in a sandwiching manner from the sides of the first blades 323 that are spaced apart from each other.

[0189] Specifically, all the first blades 323 in the blade group 322 are parallel to each other and are all fixed to the rotating shaft. All the second blades 324 are parallel to each other and are joined at the ends in their own length directions to form a frame covering the outside of the first blades 323. The second blades 324 rotate relative to the first blades 323 to form an opening and closing cut continuously.

[0190] In this way, when the second blades 324 are driven to rotate relative to the first blades 323, the adjacent blade groups 322 simultaneously shear the adventitious roots entering the shearing part 32, so that the length of the cut adventitious roots is consistent with the interval between the adjacent blade groups 322.

[0191] In this embodiment, multiple groups of blades are provided in the shearing part 32, and the blade groups 322 are arranged at fixed intervals, so that adventitious roots of consistent length can be obtained by cutting the adventitious roots, enabling the adventitious roots in the plant tissue culture tank to have the same growth state, facilitating the regular adjustment of the nutrient content of the nutrient solution and the pruning of adventitious roots, promoting the circulation of the nutrient solution in the plant tissue culture tank, maintaining stable growth conditions, and improving the cultivation efficiency and the quality of adventitious roots.

[0192] As Figure 2 shown, in another embodiment of the present invention, a cutting structure capable of being quickly disassembled and assembled is introduced. The cutting structure further includes a spacer sleeve 31 with a cylindrical outer surface. The pin shaft 321 is fixed on the top surface of the spacer sleeve 31, and at least part of the transmission part 33 is sleeved on the spacer sleeve 31.

[0193] Specifically, a circular installation hole is opened on the tank wall 11 of the plant tissue culture tank. The outer peripheral surface of the spacer sleeve 31 is set to be cylindrical and has the same diameter as the installation hole. The spacer sleeve 31 is detachably embedded in the installation hole on the tank wall 11.

[0194] One side of the spacer sleeve 31 is connected to the shearing part 32, and the other side is connected to the power part 34, for separating the shearing part 32 and the power part 34 inside and outside the plant tissue culture tank. The shearing part 32 is installed on the side of the spacer sleeve 31 facing the cavity 90 of the tank body, and the power part 34 is installed on the side of the spacer sleeve 31 facing the outside of the plant tissue culture tank. Making the cross-section of the spacer sleeve 31 larger than the cross-section of the shearing part 32 allows the shearing part 32 to be directly inserted from the installation hole, so that the cutting structure can be simply and quickly arranged on the plant tissue culture tank.

[0195] In this embodiment, a spacer sleeve 31 is provided in the plant tissue culture tank, so that the cutting structure is dispersedly installed inside and outside the tank wall 11 of the plant tissue culture tank. Thus, not only can the length of the adventitious roots be controlled by the cutting structure to maintain and promote the cultivation efficiency of the adventitious roots, but also microorganisms or impurities can be prevented from entering the plant tissue culture tank through the cutting structure, improving the sealing performance of the plant tissue culture tank.

[0196] As Figure 2 shown, in another embodiment of the present invention, a cutting structure with a cavity formed in the transmission part 33 is introduced.

[0197] The cutting part 32 and the spacer sleeve 31 are arranged at an axial interval along the pin shaft 321. The end faces of the cutting part 32 and the spacer sleeve 31 together with the inner peripheral surface of the transmission part 33 enclose a chamber for accommodating materials.

[0198] Preferably, in order to facilitate the outflow of adventitious roots from the transmission part 33. In another embodiment of the present invention, the transmission part 33 is further provided with a discharge port 333.

[0199] The discharge port 333 is opened on the side wall of the transmission part 33 and penetrates the transmission part 33 in the radial direction. A plurality of discharge ports 333 can be opened on the transmission part 33. The discharge ports 333 are evenly distributed on the side wall of the transmission part 33 in the circumferential direction.

[0200] Particularly, in the axial direction of the transmission part 33, the discharge port 333 is located between the cutting part 32 and the spacer sleeve 31. That is, the length of the discharge port 333 along the axial direction of the transmission part 33 is less than the interval length between the cutting part 32 and the spacer sleeve 31.

[0201] In order to more conveniently assemble the transmission part 33, in another embodiment of the present invention, a multi-segment spliced transmission part 33 is introduced. The transmission part 33 is set to be composed of a discharge section 331 and a driving section 332 butt-jointed.

[0202] Specifically, the discharge section 331 is sleeved on the pin shaft 321. And the discharge section 331 is provided with the discharge port 333 on the side wall. The driving section 332 is sleeved outside the spacer sleeve 31. And one end of the driving section 332 is flush with the top surface of the spacer sleeve 31.

[0203] Furthermore, in order to prevent adventitious roots from being blocked by the side wall of the transmission part 33 and accelerate the outflow of adventitious roots from the discharge port 333 after being cut by the cutting part 32. A plurality of discharge ports 333 are evenly distributed on the side wall of the discharge section 331 in the circumferential direction. Particularly, the end of the second blade 324 is connected to the side wall between adjacent discharge ports 333, so that the incision on the cutting part 32 is aligned with the discharge port 333.

[0204] As Figure 1 shown, in another embodiment of the present invention, a plant tissue culture tank is introduced. The plant tissue culture tank is provided with any one of the cutting structures in the above embodiments. Using this plant tissue culture tank to cultivate adventitious roots can improve the utilization rate of the cutting structure, enhance the cutting efficiency, reduce the opening time of the cutting structure, better maintain the growth cycle of adventitious roots, improve the cultivation efficiency of adventitious roots and the quality of adventitious roots.

[0205] The above are only the preferred embodiments of the present invention, and there is no limitation to the present invention in any form. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art of this patent can make some changes or modifications to equivalent embodiments with equivalent changes within the scope of the technical solution of the present invention by using the technical content prompted above.
