Description

Technical Field

[0001] This invention relates to the field of micrografting technology, specifically to a micrografting device and method for *Sapindus mukorossi* seedlings. Background Technology

[0002] Micrografting is an asexual reproduction method based on plant tissue culture technology. It involves transplanting a part of a plant, the scion, onto another plant, the rootstock. This process is usually carried out under sterile conditions, using special laboratory techniques to combine two different plant parts together to promote their healing and co-growth. Unlike traditional grafting, micrografting involves grafting the stem bud of a growing branch onto a topped test-tube seedling or stem segment under sterile conditions. Under suitable conditions, a new plant is cultivated. This method can overcome the disadvantages of traditional grafting, such as long propagation cycles and large variations in offspring.

[0003] During micro-grafting, due to the small size of the rootstock and scion, burrs and other problems can easily occur at the cut surfaces, affecting the grafting success rate. If the cut surfaces are uneven, have burrs, or are infected with pathogens, it will affect the healing of the rootstock and scion. Poor healing will make it difficult for the wound to heal completely, thus affecting the grafting success rate. At the same time, uneven cut surfaces may also increase the possibility of pathogen infection, leading to the death of the rootstock or scion. Furthermore, if the cuts are not completely aligned, it will also lead to adverse effects on growth, thus affecting the survival rate.

[0004] To address the problems existing in the above-mentioned prior art, we have designed a micro-grafting device and method for *Sapindus mukorossi* seedlings. Summary of the Invention

Place the prepared Xanthoceras sorbifolium seedlings into the corresponding electric gripper in turn to fix the position of the Xanthoceras sorbifolium seedlings.

[0058] S3. Flip the seedling and start the second motor. The second motor drives the drive gear to rotate, which in turn drives the driven gear to rotate.

[0082] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0083] Example 1

[0084] like Figures 1 to 9 As shown in the figure, this embodiment proposes a micro-grafting device for *Xanthoceras sorbifolium* seedlings, including a fixed frame 1, a support plate 2, a displacement component, a top shell 3, a clamping component, and a cutting component. The support plate 2 is fixedly installed on the fixed frame 1. The displacement component is installed inside the fixed frame 1 and is used to adjust the position of the seedling to be grafted. The displacement component includes a first screw 4, a first motor 5, a sliding plate 6, a transmission nut 7, and a flipping part. Two first screws 4 are symmetrically and rotatably installed on the support plate 2. The two first screws 4 are rotatably connected to the fixed frame 1. A first motor 5 is fixedly installed on the support plate 2 at the position corresponding to the two first screws 4. The output ends of the two first motors 5 are fixedly connected to the corresponding first screws 4. The sliding plate 6 is slidably installed on the fixed frame 1. A transmission nut 7 is threaded on both first screws 4. The two transmission nuts 7 are fixedly connected to the sliding plate 6. A flipping part is installed on the sliding plate 6 to drive the clamping component to flip.

[0085] Specifically, a door panel 32 is rotatably mounted on the fixed frame 1, and an observation window 33 is fixedly mounted on the door panel 32. When grafting *Xanthoceras sorbifolium* seedlings, the door panel 32 is first opened, and the prepared rootstocks are placed one by one onto the clamping components on the support plate 2. Then, the door panel 32 is closed, the top shell 3 is opened, and the prepared *Xanthoceras sorbifolium* seedlings (i.e., scions) are placed one by one onto the clamping components on the displacement component, with the grafting part facing upwards. Then, the flipping unit is activated to flip the *Xanthoceras sorbifolium* seedlings 180° so that the grafting part of the *Xanthoceras sorbifolium* seedlings faces downwards, one by one with the multiple rootstocks clamped on the support plate 2. Correspondingly, the position of the flipping part is fixed, thus fixing the position of the *Xanthoceras sorbifolium* seedling. At this time, the first motor 5 is started, which drives the first screw 4 to rotate. The first screw 4 drives the transmission nut 7 to rotate, and the transmission nut 7 drives the sliding plate 6 to move until the *Xanthoceras sorbifolium* seedling is moved onto the cutting component. The cutting component is then started to cut the grafting part of the *Xanthoceras sorbifolium* seedling and the top of the rootstock. Then, the *Xanthoceras sorbifolium* seedling after the groove is cut and the corresponding rootstock is joined together by the clamping component. Finally, plastic wrap is wrapped around the joint to complete the grafting.

[0086] The aforementioned flipping unit includes a flipping frame 8, a driven gear 9, a second motor 10, and a driving gear 11. The flipping frame 8 is rotatably mounted on the sliding plate 6. The driven gear 9 is fixedly mounted on the flipping frame 8 and is rotatably connected to the sliding plate 6. The second motor 10 is fixedly mounted on the sliding plate 6, and the driving gear 11 is fixedly mounted on the output end of the second motor 10. The driving gear 11 and the driven gear 9 mesh with each other.

[0087] Specifically, when flipping the position of the *Sapindus mukorossi* seedling, the second motor 10 is started. The second motor 10 drives the drive gear 11 to rotate, which in turn drives the driven gear 9 to rotate. The driven gear 9 then drives the flipping frame 8 to rotate. Once the flipping is complete, the second motor 10 is turned off and locked, fixing the position between the flipping frame 8 and the sliding plate 6.

[0088] The top shell 3 is rotatably mounted on the top of the fixed frame 1. Clamping components are installed on the support plate 2 and the displacement assembly to fix the position of the seedlings and rootstocks to be grafted. The clamping components include a fixed cylinder 12, a first electric cylinder 13 and an electric gripper 14. Multiple fixed cylinders 12 are fixedly installed at equal intervals on the support plate 2. Multiple fixed cylinders 12 are fixedly installed at equal intervals on the flipping frame 8. The multiple fixed cylinders 12 on the flipping frame 8 correspond one-to-one with the multiple fixed cylinders 12 on the support plate 2. A first electric cylinder 13 is fixedly installed on each of the multiple fixed cylinders 12. An electric gripper 14 is fixedly installed at the output end of each first electric cylinder 13.

[0089] Specifically, when clamping *Xanthoceras sorbifolium* seedlings and rootstocks, first open the door panel 32, and simultaneously activate the first electric cylinder 13 inside the fixing cylinder 12 on the support plate 2 to push out the corresponding electric grippers 14. Then, place the prepared rootstocks one by one onto the electric grippers 14 on the support plate 2. Then close the door panel 32, open the top shell 3, and simultaneously activate the first electric cylinder 13 inside the fixing cylinder 12 on the tilting frame 8 to push out the corresponding electric grippers 14. Place the prepared *Xanthoceras sorbifolium* seedlings one by one onto the corresponding electric grippers 14 to fix the position of the *Xanthoceras sorbifolium* seedlings. When cutting the grooves for the *Xanthoceras sorbifolium* seedlings and rootstocks, the first electric cylinder 13 on the support plate 2 and the flipping frame 8 is activated simultaneously. The electric gripper 14 pushes the corresponding *Xanthoceras sorbifolium* seedlings and rootstocks to the cutting position. After the cutting is completed, the first electric cylinder 13 on the flipping frame 8 is activated to graft the *Xanthoceras sorbifolium* seedlings onto the corresponding rootstocks. Then, the electric gripper 14 on the flipping frame 8 is released, and the flipping frame 8 is moved back to its original position. When it is necessary to remove the grafted *Xanthoceras sorbifolium* seedlings, the first electric cylinder 13 on the support plate 2 is activated, and the grafted *Xanthoceras sorbifolium* seedlings are removed using the electric gripper 14.

[0090] The cutting assembly is installed on the support plate 2 and is used to cut grooves on the clamped seedlings and rootstocks to be grafted. The cutting assembly includes a cutting cylinder 15, a cutting frame 16, a positioning frame 17, a cutting part, and a positioning part. Multiple cutting cylinders 15 are fixedly installed at equal intervals on the support plate 2. The multiple cutting cylinders 15 correspond one-to-one with the multiple fixed cylinders 12 on the support plate 2. The cutting frame 16 is symmetrically and fixedly installed on both sides of each cutting cylinder 15. The positioning frame 17 is fixedly installed at both the upper and lower ends of each cutting frame 16. Each cutting frame 16 is equipped with a cutting part for cutting the seedlings and rootstocks to be grafted. Each positioning frame 17 is equipped with a positioning part to prevent the seedlings and rootstocks from moving during the grooving process.

[0091] Specifically, once the *Sapindus mukorossi* seedling and rootstock are moved to the cutting position inside the cutting cylinder 15, the positioning unit is activated to fix their positions, and then the cutting unit is activated to cut them separately.

[0092] Specifically, the cutting section includes an annular frame 18, a connecting ring 19, a mounting groove 20, a second electric cylinder 21, a cutter 22, and a baffle plate 23. An annular frame 18 is fixedly installed on each cutting frame 16, a connecting ring 19 is rotatably installed on each annular frame 18, a mounting groove 20 is fixedly installed on each connecting ring 19, and a second electric cylinder 21 is fixedly installed on each mounting groove 20. A cutter 22 is slidably installed on one of the mounting grooves 20 inside the two cutting frames 16 on each cutting cylinder 15, and a baffle plate 23 is slidably installed on the other mounting groove 20 inside the two cutting frames 16 on each cutting cylinder 15.

[0093] Specifically, when cutting grooves on *Xanthoceras sorbifolium* seedlings and rootstocks, the angle of the groove needs to be determined as needed. By adjusting the positioning component, the corresponding connecting ring 19 is rotated on the ring frame 18, causing the mounting groove 20 to swing. Once the mounting groove 20 moves to the working position, the position between the connecting ring 19 and the ring frame 18 is fixed. The second electric cylinder 21 is then activated, driving the cutter 22 and the baffle plate 23 to move. Through the cooperation of the cutter 22 and the baffle plate 23, grooves with small tilt angle errors can be quickly and accurately cut on the *Xanthoceras sorbifolium* seedlings and rootstocks, improving the stability of the contact between them. Then, the position of the mounting groove 20 is readjusted, and the cutting is repeated to create the groove. The cooperation between the mounting groove 20 and the connecting ring 19 makes the grooves on the *Xanthoceras sorbifolium* seedlings and rootstocks smoother.

[0094] The above also includes a positioning assembly, which includes a second screw 24, a third motor 25, a second nut 26, and a connecting part. A second screw 24 is rotatably mounted on each cutting frame 16, and a third motor 25 is fixedly mounted on each cutting frame 16. The output ends of multiple third motors 25 are fixedly connected to the corresponding second screw 24. A second nut 26 is threaded onto each second screw 24, and a connecting part is installed on each second nut 26 to drive the corresponding connecting ring 19 to rotate on the ring frame 18.

[0095] Specifically, when adjusting the position of the mounting slot 20, the corresponding third motor 25 is started. The third motor 25 drives the second screw 24 to rotate, and the second screw 24 drives the second nut 26 to move. The second nut 26 can then drive the mounting slot 20 to rotate on the connecting ring 19 through the connecting part, thereby adjusting the position of the mounting slot 20.

[0096] As described above, the connecting part includes a sleeve 27 and a sleeve 28. A sleeve 27 is rotatably mounted on each second nut 26, and a sleeve 28 is slidably mounted on each sleeve 27. The sleeves 28 are fixedly connected to the corresponding mounting grooves 20.

[0097] Specifically, when adjusting the position of the mounting groove 20, during the movement of the second nut 26, the second nut 26 drives the sleeve rod 27 to move, the sleeve rod 27 drives the sleeve 28 to move, and the sleeve 28 drives the mounting groove 20 to move. At the same time, the sleeve rod 27 and the sleeve 28 slide relative to each other, thereby driving the mounting groove 20 to move.

[0098] The aforementioned positioning unit includes a third electric cylinder 29, a clamping frame 30, and an arc plate 31. A third electric cylinder 29 is fixedly installed on each positioning frame 17, a clamping frame 30 is fixedly installed on the output end of each third electric cylinder 29, and an arc plate 31 is fixedly installed on each clamping frame 30.

[0099] Specifically, when grooving the *Xanthoceras sorbifolium* seedlings and rootstocks, it is necessary to first fix the positions of the seedlings and rootstocks to prevent them from moving during cutting. At this time, multiple third electric cylinders 29 are activated. Each third electric cylinder 29 drives the corresponding clamping frame 30 to move, and each clamping frame 30 drives the corresponding arc plate 31 to move. The arc plate 31 has a certain degree of elasticity and will not damage the *Xanthoceras sorbifolium* seedlings and rootstocks. Once the seedlings and rootstocks are properly clamped, grooving can begin.

[0100] In summary, when grafting *Xanthoceras sorbifolium* seedlings, first open the door panel 32, and simultaneously activate the first electric cylinder 13 inside the fixing cylinder 12 on the support plate 2 to push out the corresponding electric gripper 14. Then, place the prepared rootstocks onto the electric gripper 14 on the support plate 2 in sequence. Next, close the door panel 32, open the top shell 3, and simultaneously activate the first electric cylinder 13 inside the fixing cylinder 12 on the flipping frame 8 to push out the corresponding electric gripper 14. Place the prepared *Xanthoceras sorbifolium* seedlings onto the corresponding electric gripper 14 in sequence, with the grafting part facing upwards, and fix the position of the *Xanthoceras sorbifolium* seedlings.

[0101] Then, the second motor 10 is started, which drives the drive gear 11 to rotate. The drive gear 11 drives the driven gear 9 to rotate, which in turn drives the rotating frame 8 to rotate. After the rotation is completed, the *Xanthoceras sorbifolium* seedling is rotated 180° so that the grafting part of the seedling is facing down. Then, the second motor 10 is turned off and locked, fixing the position between the rotating frame 8 and the sliding plate 6. At this time, the *Xanthoceras sorbifolium* seedling and the multiple rootstocks clamped on the support plate 2 correspond one-to-one. Then, the first motor 5 is started, which drives the first screw 4 to rotate. The first screw 4 drives the transmission nut 7 to rotate, and the transmission nut 7 drives the sliding plate 6 to move until the *Xanthoceras sorbifolium* seedling is moved to the set position.

[0102] When grooving the *Xanthoceras sorbifolium* seedlings and rootstocks, the first electric cylinder 13 on the support plate 2 and the flipping frame 8 is activated simultaneously. The electric gripper 14 pushes the corresponding *Xanthoceras sorbifolium* seedlings and rootstocks to the cutting position. At this time, the positions of the *Xanthoceras sorbifolium* seedlings and rootstocks need to be fixed to prevent them from moving during cutting. Then, multiple third electric cylinders 29 are activated. Each third electric cylinder 29 drives the corresponding clamping frame 30 to move. Each clamping frame 30 drives the corresponding arc plate 31 to move. The arc plate 31 has a certain degree of elasticity and will not damage the *Xanthoceras sorbifolium* seedlings and rootstocks. After the *Xanthoceras sorbifolium* seedlings and rootstocks are clamped, grooving can begin.

[0103] When making grooves on *Xanthoceras sorbifolium* seedlings and rootstocks, the groove angle needs to be determined according to requirements. While adjusting the position of the mounting groove 20, the corresponding third motor 25 is activated. The third motor 25 drives the second screw 24 to rotate, which in turn drives the second nut 26 to move. During the movement of the second nut 26, the second nut 26 drives the sleeve rod 27 to move, which in turn drives the sleeve 28 to move. The sleeve 28 then drives the mounting groove 20 to move. Simultaneously, the sleeve rod 27 and the sleeve 28 slide relative to each other, thereby adjusting the position of the mounting groove 20 and causing it to swing. When the mounting groove 20 moves to the working position... Then, the position between the connecting ring 19 and the ring frame 18 can be fixed, and the second electric cylinder 21 can be started. The second electric cylinder 21 drives the cutter 22 and the baffle plate 23 to move. Through the cooperation of the cutter 22 and the baffle plate 23, grooves with small tilt angle errors can be cut quickly and accurately on the *Sapindus mukorossi* seedlings and rootstocks, improving the stability of the contact between the two. Then, the position of the mounting groove 20 is readjusted and the cutting is repeated to cut out the groove. Through the cooperation between the mounting groove 20 and the connecting ring 19, the grooves cut on the *Sapindus mukorossi* seedlings and rootstocks are smoother. While cutting, the cutting can be observed through the observation window 33 to avoid accidents.

[0104] After cutting, start the first electric cylinder 13 on the flipping frame 8 to graft the *Xanthoceras sorbifolium* seedling onto the corresponding rootstock. Then release the electric gripper 14 on the flipping frame 8 and move the flipping frame 8 back to its original position. When it is necessary to remove the grafted *Xanthoceras sorbifolium* seedling, start the first electric cylinder 13 on the support plate 2 and use the electric gripper 14 to remove the grafted *Xanthoceras sorbifolium* seedling.

[0105] Example 2

[0106] Based on Example 1, this example also discloses a method for micro-grafting of *Xanthoceras sorbifolium* seedlings, which uses the aforementioned micro-grafting device for *Xanthoceras sorbifolium* seedlings and includes the following steps:

[0107] The first step is to feed the material. Open the door panel 32 and simultaneously start the first electric cylinder 13 inside the fixed cylinder 12 on the support plate 2 to push out the corresponding electric gripper 14. Then, place the prepared anvils into the electric gripper 14 on the support plate 2 one by one.

[0108] The second step is to place the scion, open the top shell 3, and at the same time start the first electric cylinder 13 in the fixed cylinder 12 on the flipping frame 8 to push out the corresponding electric gripper 14, and place the prepared Xanthoceras sorbifolium seedlings into the corresponding electric gripper 14 in sequence to fix the position of the Xanthoceras sorbifolium seedlings.

[0109] The third step is to flip the seedlings and start the second motor 10. The second motor 10 drives the drive gear 11 to rotate, which in turn drives the driven gear 9 to rotate. The driven gear 9 then drives the flipping frame 8 to rotate until the flipping is complete. The seedlings are then flipped 180° so that the grafting part of the seedlings faces downwards.

[0110] The fourth step is to move the seedling. Start the first motor 5, which drives the first screw 4 to rotate. The first screw 4 drives the transmission nut 7 to rotate, and the transmission nut 7 drives the sliding plate 6 to move until the seedling is moved to the set position.

[0111] The fifth step is to adjust the position. At the same time, the first electric cylinder 13 on the support plate 2 and the flipping frame 8 is activated, and the corresponding *Sapindus mukorossi* seedling and rootstock are pushed to the cutting position by the electric gripper 14.

[0112] Step 6: Positioning. Activate multiple third electric cylinders 29. Each third electric cylinder 29 drives the corresponding clamping frame 30 to move, and each clamping frame 30 drives the corresponding arc-shaped plate 31 to move until the *Sapindus mukorossi* seedling and rootstock are clamped.

[0113] Step 7: Adjustment. Start the corresponding third motor 25. The third motor 25 drives the second screw 24 to rotate, and the second screw 24 drives the second nut 26 to move.

[0114] Step 8: The second nut 26 drives the sleeve rod 27 to move, the sleeve rod 27 drives the sleeve 28 to move, and the sleeve 28 drives the mounting groove 20 to move.

[0115] Step 9: Fixing. After the mounting slot 20 is moved to the working position, the position between the connecting ring 19 and the ring frame 18 can be fixed.

[0116] Step 10: Cutting. Start the second electric cylinder 21. The second electric cylinder 21 drives the cutter 22 and the baffle plate 23 to move. Through the cooperation of the cutter 22 and the baffle plate 23, the groove is cut out.

[0117] Step 11: Grafting. Start the first electric cylinder 13 on the flipping frame 8 to graft the *Sapindus mukorossi* seedling onto the corresponding rootstock, and then release the electric gripper 14 on the flipping frame 8.

[0118] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
