Description

Technical Field

[0001] This invention belongs to the field of grafting technology, specifically, it relates to a device and method for improving the efficiency of bag grafting of mulberry trees. Background Technology

[0002] Bag grafting is a key technique in mulberry seedling cultivation. The quality and efficiency of scion cutting directly affect the grafting survival rate and the benefits of large-scale seedling production. In mulberry bag grafting, a large number of scions need to be cut obliquely in batches to ensure that the cambium layers of the scion and rootstock are in close contact, thereby improving the grafting success rate.

[0003] Currently, the existing methods for batch cutting of scions mostly involve arranging multiple scions flat and then uniformly cutting them with a blade at an angle. However, this cutting method has significant technical drawbacks. Due to the flatness of the scions during arrangement, the cutting allowance of scions at different positions is inconsistent during the cutting process. Scions near the lower part of the cutting path will produce excessively long waste material, resulting in the waste of the effective portion of the scion and significantly reducing the utilization rate of scion material. Furthermore, with the continuous increase in the demand for large-scale mulberry seedling cultivation, the amount of scions used has increased significantly, making the problem of scion waste increasingly prominent. This not only increases the cost of seedling cultivation but also reduces the overall seedling efficiency.

[0004] In view of this, the present invention is proposed. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows: A mulberry bag grafting device includes a frame and a support platform disposed above the frame. The support platform has several pairs of support cavities for supporting scions. A cutter is installed on the support platform, and the angle between the cutter and the scion is an acute angle. Each bearing cavity is equipped with a sliding push plate, which is aligned with one end of each scion. The bottom of the bearing platform is provided with a differential pushing component, which makes the pushing distance of the push plate at different positions different, ensuring that the cutter cuts the same position on each scion. The differential push component includes a rocker arm, one end of which is rotatably connected to the frame, and the surface of the rocker arm is slidably connected to the surface of the push plate. When the rocker arm swings, the push plate, which is far from the center of rotation of the rocker arm, moves a long distance, so that several scions are distributed at an angle to match the cutting angle and reduce waste generation. The support platform is also rotatably mounted with an adjusting roller. The adjusting roller has an inclined groove, which is used to drive the cutter to move down for cutting. A turntable is mounted at the center of rotation of the adjusting roller, and a switching surface is provided at one end of the turntable. When the turntable rotates, the switching surface rotates synchronously, driving the rocker arm to swing.

[0006] In a preferred embodiment of the present invention, four support legs are installed at the bottom of the frame, and rubber anti-slip pads are installed at the bottom of each of the four support legs. Adjacent support legs are supported by crossbeams, and the heights of adjacent crossbeams are different to prevent stress concentration from damaging the support legs.

[0007] In a preferred embodiment of the present invention, four uprights are installed at the bottom of the support platform, and the bottoms of the four uprights are mounted on the frame. A waste hopper is installed at the cutting position of the support platform for collecting waste.

[0008] In a preferred embodiment of the present invention, a push block is installed at the bottom of the push plate, a slide groove is provided on the support platform, the push block is slidably disposed inside the slide groove, and a positioning rod is installed through the slide groove. The positioning rod is movably connected to the push block, and a positioning spring is sleeved on the positioning rod. One end of the positioning spring is engaged with the positioning rod, and the other end of the positioning spring is engaged with the side wall of the push block. The positioning spring is used to drive the rocker arm to fit tightly against the side wall of the turntable.

[0009] In a preferred embodiment of the present invention, a synchronous shaft is installed at the rotation center of the rocker arm, the bottom of the synchronous shaft is mounted on the frame, a slot is formed on the rocker arm, and a slide rod is installed at the bottom of each push block, the bottom of the slide rod being slidably mounted on the surface of the slot.

[0010] In a preferred embodiment of the present invention, a bracket is mounted on the frame, a drive motor is mounted on the bracket, a positioning shaft is mounted on the output end of the drive motor, the positioning shaft movably passes through the bracket, and an adjusting roller is mounted on the end of the positioning shaft. The drive motor is used to drive the adjusting roller to rotate.

[0011] In a preferred embodiment of the present invention, the adjusting roller is further provided with a flat groove, and the end of the flat groove is provided with an inclined groove. A slider is installed on the flat groove, and a synchronization frame is installed on the side wall of the slider. The end of the synchronization frame is connected to the cutter. A guide rod is movably installed inside the synchronization frame. The bottom of the guide rod is installed on the frame, and a guide plate is installed on the top of the guide rod. The guide plate is used to prevent the guide rod from separating from the synchronization frame.

[0012] In a preferred embodiment of the present invention, the turntable surface is provided with a first smooth surface and a second smooth surface, and the curvature centers of the first smooth surface and the second smooth surface are the same, and the curvature radius of the first smooth surface is smaller than the curvature radius of the second smooth surface. The switching surface is smoothly connected to the first smooth surface and the second smooth surface, and when the slider slides on the flat groove surface, the switching surface is in contact with the rocker arm surface.

[0013] In a preferred embodiment of the present invention, a fixed seat is installed on each bearing cavity. The fixed seat has a slot, and a locking shaft is rotatably installed on the slot. A limiting arm is installed on the locking shaft, and a limiting plate is installed at the bottom of the limiting arm. The limiting plate corresponds to the end of the scion. A torsion spring is installed on the locking shaft, and one end of the torsion spring is engaged with the slot. The other end of the torsion spring is engaged with the limiting arm. When the scion moves, it is pressed against the limiting plate, so that the scion is in contact with the side wall of the push plate. As the pressing continues, the scion pushes the limiting plate to deflect, and the limiting plate is pressed against the outer side wall of the scion. A limiting rod is also installed on the slot, and the limiting rod is used to position the maximum angle of deflection of the limiting plate. Under the action of the push plate, the cut end of the scion branch is aligned and extends out of the limiting plate to the cut position at the lower end of the cutter.

[0014] A method for using a mulberry tree bag grafting device, the steps of which are as follows: Step 1: Equipment inspection and preparation; Step 2: Place the mulberry scions to be cut into the various bearing cavities on the bearing platform in sequence, ensuring that the scions are placed stably without any shifting or tilting. This completes the initial loading of the scions and prepares them for subsequent positioning, pushing and cutting operations. Step 3: Start the drive motor. The drive motor drives the adjusting roller and turntable to rotate synchronously through the positioning shaft. The switching surface on the turntable is in contact with the surface of the rocker arm, pushing the rocker arm to swing around the synchronous shaft. The rocker arm drives the push block and push plate to slide along the slide through the slot and slide rod. Due to the difference in distance between the rocker arm at different positions and the rotation center, the push plate of different bearing cavities pushes at different distances. Multiple scions are distributed at an angle to match the acute angle of the cutter. At the same time, the scions squeeze the limiting plate. Under the action of the torsion spring, the limiting plate presses the scions and works with the push plate to achieve precise alignment of the scions. Step 4: As the adjusting roller continues to rotate, the slider moves from the flat groove into the inclined groove. The inclined groove drives the slider to move downward. The slider drives the cutter to move smoothly down along the guide rod through the synchronous frame, and uniformly cuts all the scions that have completed positioning and angle adaptation. The waste generated by cutting naturally falls into the waste hopper for centralized collection. Step 5: After cutting is completed, control the drive motor to run in reverse to achieve reset.

[0015] Compared with the prior art, the present invention has the following advantages: This invention utilizes a sliding pusher plate on a support platform, along with a rocker arm forming a differential pushing component. This allows the pusher plate at different positions to have different pushing distances, resulting in multiple scions being arranged in an inclined distribution that matches the angle of the cutter before cutting. This ensures that the cutter cuts each scion consistently, reducing the problems of inconsistent lengths of waste material at the lower end of the scions and low material utilization in traditional batch oblique cutting. This significantly reduces scion loss. Simultaneously, through the synchronous rotation of the adjusting roller and the turntable, the rocker arm is first driven by the switching surface on the turntable to complete the differential pushing and angle adaptation of the scions. Then, the inclined groove on the adjusting roller drives the cutter to move downward to complete the cutting. This achieves sequential linkage and automated operation of scion positioning, alignment, angle adaptation, and cutting actions. The structure is compact, the operation is stable and reliable, and the efficiency of batch cutting of mulberry scions is greatly improved.

[0016] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention. Example

[0020] like Figures 1 to 9 As shown, a mulberry bag grafting device includes a frame 1 and a support platform 4 set above the frame 1. The support platform 4 has several pairs of support cavities, which are used to support scions. A cutter 15 is installed on the support platform 4, and the angle between the cutter 15 and the scion is an acute angle. Each bearing cavity is equipped with a push plate 30 that slides inside. The push plate 30 is aligned with one end of each scion. The bottom of the bearing platform 4 is equipped with a differential pushing component, which makes the pushing distance of the push plate 30 at different positions different, ensuring that the cutter 15 cuts the same position for each scion. The differential pushing component includes a rocker arm 22, one end of which is rotatably connected to the frame 1, and the surface of the rocker arm 22 is slidably connected to the surface of the push plate 30. When the rocker arm 22 swings, the push plate 30, which is far from the rotation center of the rocker arm 22, moves a long distance, causing several scions to be distributed at an angle to match the angle of the cutter 15 and reduce waste. The swing design of the rocker arm 22 can precisely control the pushing distance of the push plate 30, realize the inclined distribution of the scions, and accurately match the acute angle of the cutter 15, further reducing waste. At the same time, the rotational connection between the rocker arm 22 and the frame 1 ensures the stability and reliability of the pushing action.

[0021] The support platform 4 is also rotatably mounted with an adjusting roller 8. The adjusting roller 8 has an inclined groove 12, which drives the cutter 15 to move downward for cutting. A turntable 18 is mounted at the center of rotation of the adjusting roller 8, and a switching surface 20 is provided at one end of the turntable 18. When the turntable 18 rotates, the switching surface 20 rotates synchronously, causing the rocker arm 22 to swing. The inclined groove 12 of the adjusting roller 8 can realize the automatic downward cutting of the cutter 15 without manual operation, improving cutting efficiency. The switching surface 20 of the turntable 18 can synchronously drive the rocker arm 22 to swing, realizing the linkage between the differential push component and the cutting action of the cutter 15, simplifying the device structure, reducing the need for a power source, and reducing equipment costs.

[0022] like Figures 1 to 9 As shown in the specific embodiment, four support legs 2 are installed at the bottom of the frame 1. Each support leg 2 has a rubber anti-slip pad on its bottom, and adjacent support legs 2 are supported by crossbeams 3. The heights of adjacent crossbeams 3 are different to prevent stress concentration from damaging the support legs 2. The rubber anti-slip pads at the bottom of the support legs 2 improve the overall stability of the device, preventing slippage during operation. The crossbeams 3 of different heights effectively distribute the stress on the frame 1, preventing damage to the support legs 2 due to stress concentration, extending the service life of the frame 1 and the support legs 2, and ensuring long-term stable operation of the device.

[0023] like Figures 1 to 9 As shown, furthermore, four uprights 5 are installed at the bottom of the support platform 4, and the bottom of the four uprights 5 are mounted on the frame 1. A waste hopper 6 is installed at the cutting position of the support platform 4, and the waste hopper 6 is used to collect waste. The uprights 5 can provide stable support for the support platform 4, ensuring that the support platform 4 does not shift during the scaffold pushing and cutting process, thus improving the operation accuracy. The waste hopper 6 can collect the waste generated during cutting in a centralized manner, avoiding waste from scattering and polluting the working environment, and at the same time facilitating the unified disposal of waste in the future, thus improving the cleanliness of the working environment. Example

[0024] The difference between the above embodiments and this embodiment is that: Figures 1 to 9As shown, a push block 26 is installed at the bottom of the push plate 30, and a slide groove 27 is provided on the support platform 4. The push block 26 is slidably disposed inside the slide groove 27, and a positioning rod 28 is installed through the slide groove 27. The positioning rod 28 is movably connected to the push block 26, and a positioning spring 29 is sleeved on the positioning rod 28. One end of the positioning spring 29 is engaged with the positioning rod 28, and the other end of the positioning spring 29 is engaged with the side wall of the push block 26. The positioning spring 29 is used to drive the rocker arm 22 to fit tightly against the side wall of the turntable 18. The cooperation between the push block 26 and the slide groove 27 can realize the smooth sliding of the push plate 30. The positioning rod 28 can limit the sliding direction of the push block 26 to prevent the push block 26 from deviating. The positioning spring 29 can ensure that the rocker arm 22 fits tightly against the side wall of the turntable 18, ensuring accurate movement when the switching surface 20 of the turntable 18 drives the rocker arm 22 to swing. At the same time, it provides a reset spring force for the push plate 30, which is convenient for the continuous feeding operation of the scaffold.

[0025] like Figures 1 to 9 As shown, in a specific embodiment, a synchronous shaft 23 is installed at the rotation center of the rocker arm 22. The bottom of the synchronous shaft 23 is mounted on the frame 1. A slot 24 is formed on the rocker arm 22, and a slide rod 25 is installed at the bottom of each pusher block 26. The bottom of the slide rod 25 is slidably mounted on the surface of the slot 24. The synchronous shaft 23 can realize the stable rotation of the rocker arm 22 and ensure the concentricity of the rocker arm 22 when swinging. The cooperation between the slot 24 and the slide rod 25 can convert the swing of the rocker arm 22 into the linear sliding of the pusher block 26, realizing the synchronous and differentiated pushing of multiple pushers 30. The structure is simple and the transmission is efficient, improving the coordination and accuracy of the pushing action of the pusher 30.

[0026] like Figures 1 to 9 As shown, furthermore, a bracket 7 is mounted on the frame 1, and a drive motor 9 is mounted on the bracket 7. A positioning shaft 10 is mounted on the output end of the drive motor 9, and the positioning shaft 10 movably passes through the bracket 7. An adjusting roller 8 is mounted on the end of the positioning shaft 10. The drive motor 9 is used to drive the adjusting roller 8 to rotate. The bracket 7 enables stable mounting of the drive motor 9, and the positioning shaft 10 can transmit the power of the drive motor 9 to drive the adjusting roller 8 to rotate smoothly. The drive motor 9 provides stable power for the rotation of the adjusting roller 8 and the turntable 18, realizing automated operation of the device, reducing manual intervention, and improving the efficiency and consistency of scion cutting. Example

[0027] The difference between the above embodiments and this embodiment is that: Figures 1 to 9As shown, the adjusting roller 8 is also provided with a flat groove 11, and an inclined groove 12 is provided at the end of the flat groove 11. A slider 13 is installed on the flat groove 11, and a synchronization frame 14 is installed on the side wall of the slider 13. The end of the synchronization frame 14 is connected to the cutter 15. A guide rod 16 is installed through the synchronization frame 14. The bottom of the guide rod 16 is installed on the frame 1, and a guide plate 17 is installed on the top of the guide rod 16. The guide plate 17 is used to prevent the guide rod 16 from separating from the synchronization frame 14. The flat groove 11 can keep the slider 13 stationary before cutting, ensuring that the scion has enough time to complete the positioning and angle adaptation. The inclined groove 12 can drive the cutter 15 to move down smoothly for cutting. The synchronization frame 14 can drive the cutter 15 to move synchronously, ensuring the flatness of the cut. The guide rod 16 can limit the movement direction of the synchronization frame 14 and the cutter 15 to prevent the cutter 15 from deviating. The guide plate 17 can prevent the guide rod 16 from separating from the synchronization frame 14, ensuring the safety and stability of the cutting action.

[0028] like Figures 1 to 9 As shown, in a specific embodiment, the surface of the turntable 18 is respectively provided with a first smooth surface 19 and a second smooth surface 21, and the curvature centers of the first smooth surface 19 and the second smooth surface 21 are the same, and the curvature radius of the first smooth surface 19 is smaller than that of the second smooth surface 21. The switching surface 20 is smoothly connected to the first smooth surface 19 and the second smooth surface 21 respectively. When the slider 13 slides on the surface of the flat groove 11, the switching surface 20 is in contact with the surface of the rocker arm 22. The smooth connection between the first smooth surface 19, the second smooth surface 21 and the switching surface 20 can realize the smooth swing of the rocker arm 22 and avoid the rocker arm 22 from getting stuck. The first smooth surface 19 and the second smooth surface 21 with different curvature radii can accurately control the swing amplitude of the rocker arm 22, thereby controlling the pushing distance of the push plate 30, ensuring that the scion tilt angle is accurately matched with the cutter 15, and at the same time keeping the position of the rocker arm 22 stable when the slider 13 is in the flat groove 11, ensuring the scion positioning effect.

[0029] like Figures 1 to 9As shown, each bearing cavity is further equipped with a fixing seat 33, which has a slot 34. A retaining shaft 35 is rotatably mounted on the slot 34, and a limiting arm 31 is mounted on the retaining shaft 35. A limiting plate 32 is mounted at the bottom of the limiting arm 31, and the limiting plate 32 corresponds to the end of the scion. A torsion spring 36 is mounted on the retaining shaft 35, with one end of the torsion spring 36 engaged in the slot 34 and the other end engaged in the limiting arm 31. As the scion moves, it is pressed against the limiting plate 32, causing the scion to adhere to the side wall of the push plate 30. With continued pressing, the scion pushes the limiting plate 32 to deflect, and the limiting plate 32 presses against the outer wall of the scion. A limiting rod 37 is also installed on the slot 34, which is used to position the maximum angle of deflection of the limiting plate 32. Under the action of the push plate 30, the cut end of the scion branch aligns and extends out of the limiting plate to the cutting position at the lower end of the cutter 15. The fixing seat 33, the slot 34, and the locking shaft 35 can realize the stable installation and rotation of the limiting arm 31. The limiting plate 32, together with the torsion spring 36, can achieve precise alignment and pressing of the scion during the scion pushing process, preventing the scion from shifting. The limiting rod 37 can limit the maximum deflection angle of the limiting plate 32, avoiding excessive deflection that affects the scion positioning and subsequent limiting effect, further improving the accuracy of scion positioning and ensuring the cutting quality.

[0030] The present invention also discloses a method for using a mulberry tree bag grafting device, the steps of which are as follows: Step 1: Equipment inspection and preparation; Step 2: Place the mulberry scions to be cut into the various bearing cavities on the bearing platform 4 in sequence, ensuring that the scions are placed stably without any shifting or tilting. This completes the initial loading of the scions and prepares them for subsequent positioning, pushing and cutting operations. Step 3: Start the drive motor 9. The drive motor 9 drives the adjusting roller 8 and the turntable 18 to rotate synchronously through the positioning shaft 10. The switching surface 20 on the turntable 18 is in contact with the surface of the rocker arm 22, pushing the rocker arm 22 to swing around the synchronous shaft 23. The rocker arm 22 drives the push block 26 and the push plate 30 to slide along the slide groove 27 through the slot 24 and the slide rod 25. Due to the difference in distance between the rocker arm 22 at different positions and the rotation center, the push plate 30 of different bearing cavities pushes at different distances. Multiple scions are distributed at an angle to match the acute angle of the cutter 15. At the same time, the scions squeeze the limiting plate 32. Under the elastic force of the torsion spring 36, the limiting plate 32 presses the scions and cooperates with the push plate 30 to achieve precise alignment of the scions. Step 4: As the adjusting roller 8 continues to rotate, the slider 13 enters the inclined groove 12 from the flat groove 11. The inclined groove 12 drives the slider 13 to move downward. The slider 13 drives the cutter 15 to move smoothly down along the guide rod 16 through the synchronous frame 14, and uniformly cuts all the scions that have completed positioning and angle adaptation. The waste generated by cutting naturally falls into the waste hopper 6 for centralized collection. Step 5: After cutting is completed, control the drive motor 9 to rotate in reverse to achieve reset.

[0031] The implementation principle of the mulberry bag grafting device of the present invention is as follows: When the mulberry bag grafting device is in operation, the scions to be cut are first placed into the various bearing cavities on the bearing platform 4 in sequence to complete the initial feeding of the scions and prepare for the subsequent positioning, pushing and cutting operations.

[0032] The drive motor 9 is started, and the drive motor 9 drives the adjusting roller 8 to rotate via the positioning shaft 10. During the rotation of the adjusting roller 8, the slider 13 first slides in the flat groove 11 of the adjusting roller 8. At this time, the cutter 15 keeps its height constant. At the same time, the adjusting roller 8 drives the turntable 18 to rotate synchronously. The switching surface 20 on the turntable 18 rotates accordingly and comes into contact with the surface of the rocker arm 22, pushing the rocker arm 22 to swing around the synchronous shaft 23. When the rocker arm 22 swings, the slot 24 on its surface drives the push block 26 to move via the slide rod 25. The push block 26 then drives the push plate 30 to slide along the slide groove 27. Since the distance between different positions on the rocker arm 22 and the rotation center is different, the push plate 30, which is farther away from the rotation center of the rocker arm 22, moves a longer distance, thus pushing the scion in the corresponding bearing cavity to move a different distance. This ensures that multiple scions are distributed at an angle, matching the angle of the cutter 15. This ensures that the cutter 15 maintains a consistent cutting position for each scion, while reducing cutting waste. (Note that when placing the scion and during cutting, the cutting surface and the scion bud must not be on the same side, i.e., opposite sides. The angle between the cutter 15 and the cutting surface of the scion extending from the bearing cavity is an acute angle. This acute angle should have a specific value, and according to the principle of the largest and sharpest cutting end area, it should be around 70°. The direction of the drive motor 9 when the cutter 15 moves downward during cutting and when the cutter 15 moves upward after cutting are opposite. That is, cutting and resetting are two-way operations in one cutting cycle.)

[0033] During the movement of the scion by the pusher plate 30, the scion contacts and is pressed against the limiting plate 32. At this time, under the elastic force of the torsion spring 36, the limiting arm 31 drives the limiting plate 32 to press against the side wall of the scion, achieving precise alignment of the scion in conjunction with the pusher plate 30. As the pusher plate 30 continues to push the scion, the scion will push the limiting plate 32 to rotate as a whole. When the scion passes the limiting plate 32, the limiting plate 32 covers the surface of the scion under the elastic force of the torsion spring 36, further limiting and fixing the scion to prevent it from shifting during subsequent cutting. When placing the scion in the scion bearing cavity, the bud of the scion should be placed upwards in the same direction as the pusher plate 30, which is the non-cut end. Furthermore, a cutting length of about 4 cm should be reserved below the bud of the selected scion to ensure that the bud is not cut.

[0034] Meanwhile, the positioning spring 29 provides a reset force for the push block 26, ensuring that the slide bar 25 is always in close contact with the slot 24, and also keeping the rocker arm 22 in stable contact with the side wall of the turntable 18, ensuring that the pushing action is accurate and reliable; the limiting rod 37 limits the maximum deflection angle of the limiting plate 32, preventing it from deflecting excessively and affecting the scion positioning effect and the normal function of subsequent covering and limiting.

[0035] As the adjusting roller 8 continues to rotate, the slider 13 enters the inclined groove 12 from the flat groove 11. The inclined groove 12 drives the slider 13 to move downward. The slider 13 drives the cutter 15 to move smoothly down along the guide rod 16 through the synchronous frame 14, and uniformly cuts the scions that have completed positioning and angle matching. The waste generated by cutting falls into the waste hopper 6 for centralized collection.

[0036] After cutting, the device is reset by the drive motor 9. At this time, the adjusting roller 8 rotates synchronously, the slider 13 returns to the flat groove 11 along the inclined groove 12, and the cutter 15 moves upward and resets under the limit of the guide rod 16 and the guide plate 17. At the same time, the turntable 18 rotates, the switching surface 20 leaves the rocker arm 22, and the rocker arm 22 swings back under the reset action of the positioning spring 29. The push plate 30 is reset accordingly, and the limit plate 32 is also reset under the action of the torsion spring 36. Then the next batch of scions can be loaded and cut. The whole device realizes the integrated operation of differential scion pushing and alignment, angle adaptation and automatic cutting through the synchronous movement of the adjusting roller 8 and the turntable 18. This not only ensures the uniformity of the scion cutting position, but also improves the efficiency and quality of mulberry bag grafting scion cutting.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.

8. A method for improving the efficiency of bag grafting in mulberry trees, characterized in that, The method steps of using the device for improving the efficiency of mulberry bag grafting as described in claim 7 are as follows: Step 1: Equipment inspection and preparation; Step 2: Place the mulberry scions to be cut into the various bearing cavities on the bearing platform (4) in sequence, ensuring that the scions are placed stably without any deviation or tilting, and complete the initial feeding of the scions to prepare for subsequent positioning, pushing and cutting operations. Step 3: Start the drive motor (9). The drive motor (9) drives the adjusting roller (8) and the turntable (18) to rotate synchronously through the positioning shaft (10). The switching surface (20) on the turntable (18) is in contact with the surface of the rocker arm (22), pushing the rocker arm (22) to swing around the synchronous shaft (23). The rocker arm (22) drives the push block (26) and the push plate (30) to slide along the slide groove (27) through the slot (24) and the slide rod (25). Due to the difference in distance between the rocker arm (22) at different positions and the rotation center, the push plate (30) of different bearing cavities pushes at different distances. Multiple scions are distributed at an angle to match the acute angle of the cutter (15). Cutting and resetting are two-way operations in one cutting cycle. At the same time, the scions squeeze the limiting plate (32). Under the elastic force of the torsion spring (36), the limiting plate (32) presses the scions and cooperates with the push plate (30) to achieve precise alignment of the scions. Step 4: As the adjusting roller (8) continues to rotate, the slider (13) enters the inclined groove (12) from the flat groove (11). The inclined groove (12) drives the slider (13) to move downward. The slider (13) drives the cutter (15) to move smoothly down along the guide rod (16) through the synchronous frame (14). All the scions that have completed positioning and angle matching are cut uniformly. The waste generated by cutting naturally falls into the waste hopper (6) for centralized collection. Step 5: After cutting is completed, control the drive motor (9) to run in reverse to achieve reset.
