Description

Technical Field

[0001] This utility model relates to the field of Dendrobium orchid cultivation technology, and in particular to a device for separating the buds of Dendrobium orchid tissue culture seedlings. Background Technology

[0002] Dendrobium orchids are precious plants with both high ornamental and medicinal value. In the complete process of Dendrobium orchid tissue culture, the division of bud clusters is a key intermediate step connecting propagation culture and rooting culture. The quality of the division operation directly affects the survival rate, rooting rate, and subsequent growth of seedlings, and has a decisive impact on the quality and overall yield of the final tissue culture seedlings. It is a core step that cannot be ignored in tissue culture production.

[0003] However, existing cutting tools for separating Dendrobium orchid tissue culture seedlings often have fixed blade shapes, which cannot be flexibly adjusted according to actual planting needs. Different Dendrobium orchid varieties exhibit natural differences in growth characteristics and tissue structure in their bud separation, and the morphology requirements for the cutting surface also vary. Fixed blade shapes are difficult to adapt to these diverse needs. Inappropriate cutting surface shapes may lead to slow wound healing, significantly increasing the risk of infection, or affecting the subsequent contact between the wound and the culture medium, thereby inhibiting the rooting process and growth of the bud, ultimately reducing the overall quality and growth consistency of the tissue culture seedlings.

[0004] Secondly, existing slitting devices generally lack effective real-time disinfection capabilities, requiring operators to perform separate disinfection procedures after slitting. This separate operation mode not only increases the complexity of the workflow and prolongs the processing time for individual bud clusters, but also increases the risk of cross-contamination between different bud clusters due to tool residue. Cross-contamination can directly lead to rotting and necrosis of the bud clusters. Utility Model Content

[0005] The main purpose of this invention is to provide a device for cutting the buds of Dendrobium officinale tissue culture seedlings. This device can effectively solve the problem that the blades of existing cutting tools are difficult to adapt to the diverse cut surface requirements of Dendrobium officinale cultivation, and that existing cutting tools lack disinfection treatment after cutting, which can easily lead to cross-infection between the buds.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A device for dividing the buds of Dendrobium tissue culture seedlings includes dividing shears, the dividing shears including two handles that are rotatably connected in a cross direction, one end of one handle being fixedly connected to a main shear and the other end of the handle being fixedly connected to an auxiliary shear; The main shears are provided with a first component on one side. The first component is used to change the shape of the blade produced by the cutting shears after cutting the Dendrobium nobile buds. The blade of the main shears is provided with an installation groove. The first component includes a replacement blade that is detachably connected to the installation groove. A second component is provided on one side of the main shears. After the cutting shears cut the Dendrobium nobile bud clusters, the second component is used to disinfect the cut surfaces of the bud clusters.

[0007] Preferably, at least two replacement blades are provided, and the cutting surfaces of the two replacement blades are a horizontal surface and an inclined surface, respectively.

[0008] Preferably, the top surface of the replacement blade is provided with a mating groove, and a washer is slidably connected inside the mating groove. Two symmetrically distributed screws are threaded through the top surface of the washer, and the screws are threadedly connected to the main shear.

[0009] Preferably, the second component includes a nozzle fixedly connected to one side of the main shear, the nozzle spraying in a direction toward the cutting edge of the replacement blade.

[0010] Preferably, the second component further includes a storage bottle disposed on one side of the slitting shear and an injection cylinder rotatably connected between the two handles, wherein an inlet pipe is connected between the storage bottle and the injection cylinder, and an outlet pipe is connected between the injection cylinder and the nozzle.

[0011] Preferably, a first check valve is provided at one end of the inlet pipe near the syringe, and a second check valve is provided at the other end of the inlet pipe near the syringe.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 1. In this utility model, the detachable structure of the replacement blade allows operators to easily change the replacement blade with a horizontal or beveled cutting surface according to the different characteristics, growth stages, and subsequent planting and cultivation needs of Dendrobium nobile buds, thereby obtaining a suitable blade cut shape. This flexible and adaptable design can meet diverse tissue culture needs, providing a good foundation for wound healing and root growth of buds, effectively improving the versatility and adaptability of the cutting device, avoiding the adverse effects on bud growth caused by improper blade shape, and broadening the application scenarios of the device.

[0013] 2. This invention links the syringe and handle, utilizing the power of the handle's opening and closing during the cutting process to drive the extraction and spraying of disinfectant liquid. After cutting, the nozzle can immediately and accurately spray disinfectant liquid onto the cutting area, ensuring the timeliness and targeted nature of the disinfection operation. This integrated design not only avoids cross-infection caused by untimely disinfection after cutting, but also effectively reduces the risk of rotting and necrosis of clustered buds, ensuring the quality and survival rate of tissue culture seedlings.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figure 1 and Figure 2 As shown, a device for dividing the buds of Dendrobium tissue culture seedlings includes a dividing shear 1. The dividing shear 1 includes two handles 11 that are rotatably connected in a cross direction. One end of one handle 11 is fixedly connected to a main shear 12, and one end of the other handle 11 is fixedly connected to an auxiliary shear 13. A first component 2 is provided on one side of the main shear 12. The first component 2 is used to change the blade shape produced by the cutting shear 1 after cutting the Dendrobium bud clusters. The blade surface of the main shear 12 has an installation groove 121. The first component 2 includes a replacement blade 21 that is detachably connected in the installation groove 121.

[0018] At least two replacement blades 21 are provided, and the cutting surfaces of the two replacement blades 21 are a horizontal surface and an inclined surface, respectively.

[0019] The top surface of the replacement blade 21 is provided with a mating groove 22, and a washer 23 is slidably connected inside the mating groove 22. The top surface of the washer 23 is threadedly connected with two symmetrically distributed screws 24, and the screws 24 are threadedly connected to the main shear 12.

[0020] It should be noted that a spring is fixedly connected between the two handles 11, and the spring is used to assist the two handles 11 in resetting; the horizontal replacement blade 21 can achieve flat cutting, which is suitable for the cultivation of clustered buds where the flatness of the cutting surface is required and rapid healing is needed; the slanted replacement blade 21 can cut out slanted blade surfaces, which can increase the contact area between the cutting surface and the culture medium, or adapt to specific planting angles and growth environment requirements. By tightening the screw 24, the washer 23 and the replacement blade 21 can be firmly fixed in the mounting groove 121. On the other hand, the washer 23 and the replacement blade 21 can be removed by unscrewing the screw 24. This connection method allows the operator to easily replace the replacement blade 21 with different cutting surfaces according to actual needs. The operation is simple and efficient, and the fixing effect is reliable.

[0021] like Figure 1 - Figure 4 As shown, a second component 3 is provided on one side of the main shear 12. After the cutting shear 1 cuts the Dendrobium bud clusters, the second component 3 is used to disinfect the cut surfaces of the clusters.

[0022] Preferably, the second component 3 includes a nozzle 31 fixedly connected to one side of the main shear 12, and the nozzle 31 sprays in a direction toward the cutting edge of the replacement blade 21.

[0023] The second component 3 also includes a storage bottle 32 disposed on one side of the slitting shear 1 and an injection cylinder 33 rotatably connected between the two handles 11. An inlet pipe 34 is connected between the storage bottle 32 and the injection cylinder 33, and an outlet pipe 35 is connected between the injection cylinder 33 and the nozzle 31.

[0024] A first check valve 36 is provided at one end of the inlet pipe 34 near the syringe 33, and a second check valve 37 is provided at the other end of the inlet pipe 34 near the syringe 33.

[0025] It should be noted that the nozzle 31 is fixedly connected to one side of the main shear 12, and its spray direction is precisely calibrated to face the blade of the replacement blade 21, so as to ensure that after the cutting is completed, the disinfectant liquid sprayed by the nozzle 31 can accurately act on the blade area where the new shoots have just formed, so as to achieve targeted disinfection. Storage bottle 32 contains a sufficient amount of disinfectant liquid to meet the disinfection requirements for batch cutting; The two ends of the syringe 33 are rotatably connected to two handles 11 respectively. The handles 11 serve as the power source for the movement of the piston rod inside the syringe 33. When the user cuts the clustered buds with the slitting shears 1, the movement of the handles 11 can automatically drive the movement of the syringe 33. The No. 1 check valve 36 and the No. 2 check valve 37 work together to ensure that the liquid can only enter the syringe 33 from the inlet pipe 34 and can only leave the syringe 33 from the outlet pipe 35.

[0026] Working principle: First, select a suitable replacement blade 21 based on the variety, growth stage, and subsequent planting needs of the Dendrobium orchid buds to be cut. When replacing the replacement blade 21, the user first uses a tool to loosen the two screws 24 on the top surface of the washer 23. After the screws 24 are loosened, the washer 23 and the replacement blade 21 are released from their fixed position, allowing the original replacement blade 21 to be removed from the mounting slot 121 of the main shear 12. Then, the user places the selected replacement blade 21 into the mounting slot 121, adjusting the position of the washer 23 within the mating slot 22 so that the blade surface of the replacement blade 21 is fully engaged with the blade surface of the auxiliary shear 13, ensuring uniform shearing force during the cutting process. After adjustment, tighten the two symmetrically distributed screws 24, and secure the washer 23 and the replacement blade 21 within the mounting slot 121 through the threaded connection between the screws 24 and the main shear 12. This completes the replacement and assembly of the replacement blade 21, at which point the device is capable of cutting according to the corresponding blade shape.

[0027] Subsequently, the operator holds the two handles 11 of the cutting shears 1 with both hands, places the Dendrobium officinale tissue culture seedling cluster buds to be cut between the replacement blade 21 of the main shears 12 and the auxiliary shears 13, and precisely aligns them with the position to be cut to ensure accurate cutting position and avoid damage to the healthy tissue of the cluster buds.

[0028] Next, the operator squeezes the two handles 11 together. The handles 11 rotate around the cross-rotation connection, causing the main shears 12 and the auxiliary shears 13 to move closer to each other. The blades of the replacement blade 21 and the auxiliary shears 13 interact to generate precise shearing force, cutting off the clustered buds at the predetermined position. Depending on the blade shape of the selected replacement blade 21, a flat or inclined cut surface is formed.

[0029] During the cutting process by squeezing the handles 11, the relative rotation of the two handles 11 synchronously drives the syringe 33 connected between them to work. When the handles 11 are continuously squeezed, the internal volume of the syringe 33 shrinks, generating a positive thrust. At this time, the first one-way valve 36 closes and the second one-way valve 37 opens. The disinfectant liquid stored in the syringe 33 is pushed to the nozzle 31 through the outlet pipe 35 under the thrust. The nozzle 31 sprays the disinfectant liquid in a uniform spray form at the cut surface formed by the cutting of the clustered buds, achieving the effect of immediate disinfection after cutting.

[0030] After the cutting is completed, the user releases the handle 11. Under the action of the spring between the two handles 11, the two handles 11 move away from each other. At this time, the syringe 33 is under negative pressure. At this time, the first one-way valve 36 on the liquid inlet pipe 34 opens and the second one-way valve 37 closes. The disinfectant liquid in the storage bottle 32 is smoothly drawn into the syringe 33 through the liquid inlet pipe 34 under the action of negative pressure, thus completing the extraction of disinfectant liquid.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
