Description

Technical Field

[0001] This invention relates to the field of hybrid tulip tree technology, and particularly to a device for pruning and dwarfing hybrid tulip trees. Background Technology

[0002] The hybrid tulip tree (Liriodendron tulipifera) is a plant belonging to the genus Liriodendron in the family Magnoliaceae. It is a hybrid cultivated from Chinese tulip tree and North American tulip tree. The hybrid tulip tree has some unique characteristics. Its trunk is straight, its crown is conical, and its leaves are similar in shape to a goose's foot. The leaves are large and unique. Ecologically, it has certain ornamental value. Its beautiful tree shape and unique leaf shape can be used for landscaping and greening. At the same time, the hybrid tulip tree also has a certain degree of adaptability to the environment. It is also of great significance in scientific research and conservation. It is one of the achievements of plant hybridization breeding and plays a positive role in enriching plant species resources and protecting biodiversity. The hybrid tulip tree is a plant with unique morphology and important value.

[0003] In order to control the height and shape of hybrid tulip trees or promote the growth of lateral branches during their early growth, the top of the tree can be pruned to dwarf it. First, pruning helps to shape a more ideal tree shape. If the growth of hybrid tulip trees is not controlled, the trunk will be too tall and the tree shape will be irregular. Pruning can guide its growth form, making it more beautiful and neat, which meets the design requirements of garden landscape or specific scenes. Second, controlling the height of the plant makes subsequent management and maintenance easier. Overly tall hybrid tulip trees will cause inconvenience in pruning and pest and disease control. Pruning can reduce the difficulty of operation and improve management efficiency.

[0004] However, in current techniques for dwarfing hybrid tulip trees during their early stages, the topping is typically done directly by gardeners. Firstly, if the gardeners lack sufficient understanding of the tulip tree's growth characteristics and dwarfing requirements, they may choose inappropriate topping locations and heights, resulting in unsatisfactory dwarfing effects and failing to achieve the desired landscape shape or other goals. Secondly, if the gardeners are unskilled or operate improperly, the cut at the top of the hybrid tulip tree may be uneven, increasing the risk of pathogen infection and negatively impacting the plant's health. Furthermore, improper pruning techniques, such as excessive topping, can severely impact the normal growth and development of Liriodendron tulipifera. When pruning hybrid Liriodendron tulipifera to achieve a flat top through multiple pruning steps, the branches are repeatedly cut, leading to friction damage at the cut surfaces. This can result in excessive damage to the plant's cut surfaces, causing poor growth and sparse foliage. Therefore, a device for pruning and dwarfing hybrid Liriodendron tulipifera is needed to address these issues. Summary of the Invention

[0010] As a further improvement to the above solution, the coating component also includes slide rods symmetrically slidably connected inside the gathering plate two.

The interior of the insecticidal cartridge is symmetrically slidably connected with mounting rods. A sealing plate is fixedly connected to the top of each mounting rod, and an L-shaped plate is slidably connected to the bottom of each mounting rod. A compression spring is sleeved on the outer wall of each mounting rod, with both ends of the compression spring fixedly connected to the bottom of the insecticidal cartridge and the L-shaped plate, respectively.

[0015] As a further improvement to the above solution, the two insecticide tanks are arranged on both sides of the application roller, and the insecticide tanks and the cutting blade are staggered.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. When the telescopic shaft of the miniature electric pneumatic rod drives the bevel gear one to mesh with the bevel gear two, the rotation of the reciprocating screw causes the cross rod and the double-acting screw to rotate. The rotation of the double-acting screw allows the gathering plates one and two to move towards the center, gathering the top branches and leaves of the tulip tree between the gathering plates one and two towards the center. Then, by moving the cutting blade, the gathered part of the tulip tree can be cut off and dwarfed. This is a significant improvement over the existing technology that cuts off the top branches and leaves of the tulip tree when they are spread out. This method avoids repeatedly pruning and dwarfing the top branches of the tulip tree. Instead, by gathering the branches and leaves before pruning, and using gathering boards one and two to gather the branches and leaves, pruning becomes easier and more efficient. Workers can more clearly see the overall structure of the tree, accurately prune, remove excess branches, diseased branches, and weak branches, maintaining the tree's health and good shape. Furthermore, the tree structure is more compact after gathering the branches and leaves using gathering boards one and two, promoting better growth. Maintenance personnel can more easily conduct thorough inspections without having to search for signs of pests and diseases among scattered branches and leaves, saving time and effort and improving inspection efficiency. By using gathering plates one and two to gather the branches and leaves at the top of the tulip tree in one go, the dwarfing and trimming of the top branches and leaves can be completed, improving the efficiency of dwarfing and trimming while avoiding damage to the leaves caused by repeated dwarfing. Meanwhile, the retraction of bevel gear one, driven by the telescopic shaft of miniature electric pneumatic rod one, separates it from bevel gear two. When the double-acting screw and cross bar stop rotating, the double-acting screw's double-acting thread allows the first and second gathering plates to be stably stopped at the set position. The self-locking effect of the thread further stabilizes the gathering of the tulip trees by making the gathering plates more stable. The second gathering position fixation of the tulip trees further ensures that the position of the tulip trees does not wobble during the dwarfing process. The dwarfing cut is more neat when the tulip trees are stably dwarfed, further improving the aesthetics of the dwarfing process.

[0018] 2. The compression spring's own elasticity ensures the coating roller and coating sponge sleeve firmly contact the branch and leaf cut-off points at different heights. The fixed box drives the movement of the coating roller and coating sponge sleeve, applying protective agent to the entire cut-off point of the tulip tree branch and leaf. The discharge hole on the surface of the coating roller allows the protective agent inside to fully saturate the coating sponge sleeve. When the protective agent-saturated coating sponge sleeve moves to the branch and leaf cut-off point, the pressure from the tight contact between the sleeve and the cut-off point forces the protective agent to adhere. The protective agent is applied to the cut ends of branches and leaves, providing protection. The fixed rack is in a limited position, and the rotating gear, engaged with it, rotates during movement. The rotation of the application roller and the application sponge ensures continuous and tight contact between the agent-soaked sponge and the cut ends, guaranteeing even application of the agent to each branch and leaf cut. This ensures comprehensive and even coverage of all cut areas, preventing any omissions.

[0019] 3. When the ear plate and L-shaped plate are retracted by the telescopic shaft of the miniature electric pneumatic rod two, the L-shaped plate can be moved to a position where it can abut against the fixed arc-shaped protrusion during the reciprocating sliding of the fixed arc-shaped protrusion. The reciprocating sliding of the fixed arc-shaped protrusion, along with its protrusion, causes the L-shaped plate to be pressed up and down and then reset. When the L-shaped plate is pressed upwards, the sealing plate is opened under the action of the mounting rod, allowing the insecticide to be released. When the ear plate and L-shaped plate are in the extended state, driven by the telescopic shaft of the miniature electric pneumatic rod two, the fixed arc-shaped protrusion remains in a non-contact state with the L-shaped plate during its continuous reciprocating movement. At this time, the L-shaped plate is not in contact with the fixed arc-shaped protrusion. Under the squeezing action of the L-shaped protrusion, the L-shaped plate will always maintain its original state, and the sealing plate will also maintain its original state under the action of the mounting rod and the L-shaped plate, so that the insecticide inside the insecticide box is in a closed state and cannot be sprayed. By displaying these two states, it is possible to spray insecticide on the tulip tree when it is necessary, and to prevent insecticide spraying when it is not necessary. This makes it easy to adjust whether to spray insecticide according to the growth status of the tulip tree itself. Moreover, the insecticide in the insecticide box can also be replaced with nutrient solution as needed, and the spraying can be controlled according to the specific growth status of the tulip tree. This allows for operation based on specific conditions after the tulip tree is pruned and dwarfed.

[0020] 4. When the ear plate and L-shaped plate are retracted by the telescopic shaft of the miniature electric pneumatic rod II, the L-shaped plate slides upwards due to the upward pressure of the arc-shaped protrusion of the fixed arc-shaped protrusion during its reciprocating sliding motion. As the L-shaped plate slides upwards, the sealing plate can be disengaged from the atomizing spray plate under the connection of the mounting rod. The retraction of the L-shaped plate ensures continuous reciprocating contact between the L-shaped plate and the fixed arc-shaped protrusion during their reciprocating motion, allowing the protrusion of the fixed arc-shaped protrusion to achieve the reciprocating up-and-down movement of the L-shaped plate. This reciprocating up-and-down movement of the L-shaped plate allows the sealing plate to open and close intermittently. The intermittent opening of the sealing plate allows insecticide or nutrient solution inside the insecticide box to flow into the atomizing spray plate through the gap between the insecticide box and the sealing plate. The outflow of insecticide or nutrient solution achieves the effect of spraying onto the tulip tree. The closing of the sealing plate allows the insecticide to be sprayed onto the tulip tree. The insecticide or nutrient solution inside the spray box cannot flow into the atomizing spray plate through the gap between the insecticide box and the sealing plate. This allows the insecticide or nutrient solution to flow out and spray onto the tulip tree. The intermittent opening and closing of the spray box allows for spraying when needed, improving the flexibility of insecticide or nutrient spraying. The atomizing spray plate sprays the insecticide or nutrient solution onto the pruned and dwarfed leaves. When the L-shaped plate slides down, the compression spring is compressed. When the L-shaped plate slides down, the rebound force of the compression spring causes the sealing plate to contact the atomizing spray plate again, preventing the insecticide or nutrient solution from spraying out. The intermittent contact and disengagement between the sealing plate and the atomizing spray plate allows for the intermittent spraying of insecticide or nutrient solution onto the branches. This intermittent spraying mode ensures sufficient protection during critical periods while avoiding the negative effects of overuse of insecticides.

[0021] 5. By pulling the two arc-shaped clamps apart and placing them on both sides of the tulip tree, the friction pads can be made to come into tight contact with the tulip tree, which can stably fix the equipment at the root position of the tulip tree. This allows the equipment to be accurately placed on one side of the tulip tree. The stabilizing rods can be pressed down into the soil by stepping on the pedal. The stability of the overall equipment placement can be further improved by inserting multiple stabilizing rods into contact with the ground. Attached Figure Description

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 skilled in the art without creative effort are within the protection scope of the present invention.

[0038] Please see Figures 1 to 9 As shown, the present invention provides an embodiment: a dwarfing device for hybrid tulip tree, including a base plate 1 and a support rod 2. The support rod 2 is fixedly connected to the outer wall of the base plate 1. A lifting mechanism is provided inside the support rod 2. A stabilizing component 4 for increasing the overall bottom stability is provided on the side of the base plate 1 away from the support rod 2. A fixing plate 3 is slidably connected to the outer wall of the support rod 2. A pruning component 5 for gathering and pruning the branches and leaves at the top of the hybrid tulip tree is provided inside the fixing plate 3. A coating component 6 for applying a protective agent to the cut-off position of the branches is provided on the pruning component 5. An insecticidal component 7 for spraying insecticide on the top of the hybrid tulip tree.

[0039] The truncating assembly 5 includes a bidirectional lead screw 501 and a cross rod 502 rotatably connected inside the fixed plate 3. The outer wall of the bidirectional lead screw 501 is symmetrically threaded with movable plates 503. Both movable plates 503 are slidably connected to the outer wall of the cross rod 502. The outer walls of the two movable plates 503 are respectively fixedly connected to a first gathering plate 504 and a second gathering plate 505. A drive motor 506 is fixedly connected to the end of the second gathering plate 505 away from the movable plates 503. The output shaft of the drive motor 506 is fixedly connected to a reciprocating lead screw 507. A miniature electric pneumatic rod 508 is fixedly connected to one end of the reciprocating screw 507 away from the drive motor 506. A bevel gear 509 is fixedly connected to the telescopic shaft of the miniature electric pneumatic rod 508. A bevel gear 510 is rotatably connected to the outer wall of one of the moving plates 503. The bevel gear 510 and the bevel gear 509 mesh with each other. A cross groove 511 is opened inside the bevel gear 510. The cross groove 511 is slidably connected to the outer wall of the cross rod 502. The bidirectional screw 501 and the cross rod 502 are connected by belt drive.

[0040] The top-cutting assembly 5 also includes a slide plate 512 that is slidably connected to the reciprocating lead screw 507. A fixed box 513 is fixedly connected to the top of the slide plate 512. Cutting drive mechanisms 514 are fixedly connected to both sides of the fixed box 513. Cutting blades 515 are provided inside the cutting drive mechanisms 514.

[0041] Specifically, by moving the gathering plates 504 and 505 in the pruning component 5 towards each other, the hybrid tulip trees located between the gathering plates 504 and 505 are gathered together. After the hybrid tulip trees are gathered, the top of the gathered tulip trees is pruned and dwarfed simultaneously by activating the pruning blade 515. By first gathering and pruning the branches and leaves at the pruning location of the hybrid tulip trees, the overall shape and structure of the trees can be better planned and adjusted to better meet specific landscape design or styling requirements. This helps to create a more regular, beautiful, and unique tree shape. Secondly, gathering before pruning allows for more precise control of the pruning position and degree, avoiding the adverse effects that may result from arbitrary pruning, such as unnecessary interference with growth. It ensures that the pruning operation is just right, achieving the expected purpose while reducing potential adverse effects on tree growth and health.

[0042] The applicator 6 includes fixed rods 601 symmetrically fixedly connected inside the fixed box 513. A slider 602 is slidably connected to the outer wall of the fixed rods 601. A T-shaped plate 603 is fixedly connected to the outer wall of the slider 602. A rotating shaft 604 is rotatably connected to the side of the T-shaped plate 603 away from the slider 602. An applicator roller 605 is fixedly connected to the end of the rotating shaft 604 away from the T-shaped plate 603. A rotating gear 606 is fixedly connected to the outer wall of the rotating shaft 604. An applicator sponge sleeve 609 is fixedly connected to the outer wall of the applicator roller 605. The outer wall of the applicator roller 605 has discharge holes 608 arranged in a circumferential array. A compression spring 607 is sleeved on the outer wall of each fixed rod 601. The two ends of the compression spring 607 are fixedly connected to the inner wall of the fixed box 513 and the slider 602, respectively.

[0043] The application component 6 also includes a slide rod 610 symmetrically slidably connected inside the gathering plate 505. A fixed rack 611 is fixedly connected to the top of the slide rod 610, and a baffle 612 is fixedly connected to the bottom of the slide rod 610. A tension spring 613 is sleeved on the outer wall of the slide rod 610. The two ends of the tension spring 613 are fixedly connected to the inner wall of the gathering plate 505 and the baffle 612, respectively. The fixed rack 611 and the rotating gear 606 mesh with each other.

[0044] Specifically, by moving and rotating the application roller 605 in the application component 6 at the cut end of the branch, the protective agent soaked in different positions on the application sponge sleeve 609 can be applied more evenly to the cut end. Applying the protective agent by rotating it at the cut end of the branch has many important advantages. First, it ensures that the protective agent covers all parts of the cut end more evenly and comprehensively, avoiding any missed areas. Comprehensive coverage can provide broader and more effective protection for the cut end. Second, the rotating application method helps the protective agent to better penetrate into the fine gaps of the cut end and into the tissue, thereby enhancing the protective effect and effectively blocking the invasion of adverse external factors, such as bacteria and excessive evaporation of moisture.

[0045] The insecticidal component 7 includes an insecticidal cartridge 701 symmetrically fixedly connected to the upper surface of the fixed box 513. Fixed arc-shaped protrusions 702 are symmetrically fixedly connected to the upper surface of the cutting blade 515. Installation rods 703 are symmetrically slidably connected inside the insecticidal cartridge 701. A sealing plate 704 is fixedly connected to the top of each installation rod 703. An L-shaped plate 706 is slidably connected to the bottom of each installation rod 703. A compression spring 707 is sleeved on the outer wall of each installation rod 703. The two ends of the compression spring 707... The bottom of the insecticide box 701 and the L-shaped plate 706 are fixedly connected respectively. The upper surface of the L-shaped plate 706 is fixedly connected with the ear plate 708. The outer wall of the mounting rod 703 is fixedly connected with the mini electric air rod 709. The telescopic shaft of the mini electric air rod 709 is fixedly connected with the ear plate 708. The bottom of the insecticide box 701 is provided with a spray port. The inside of the spray port is fixedly connected with the atomizing spray plate 705. The bottom of the atomizing spray plate 705 is fixedly connected with the atomizing nozzles arranged in a linear array.

[0046] Specifically, the insecticide in the insecticide component 7 can be continuously and intermittently sprayed onto the cut branches of the tulip tree. First, this method can continuously and effectively suppress various pests that breed at the cut site. Since the top is relatively vulnerable after being cut and dwarfed, it is easy for pests to attack. Intermittent spraying of insecticide can control potential pest threats in a timely manner, ensuring the safety of new growth points and cut sites, avoiding damage from pests, and ensuring the normal growth and development of the tulip tree. Second, the intermittent spraying mode can ensure sufficient protection during critical periods while avoiding the negative effects of overuse of insecticide.

[0047] The stabilizing component 4 includes arc-shaped clamping plates 401 that are symmetrically slidably connected inside the base plate 1. Friction pads 402 are fixedly connected to the surfaces of the two arc-shaped clamping plates 401 that are close to each other. Stabilizing inserts 403 are fixedly connected to the bottom of the two arc-shaped clamping plates 401. Pedals 404 are fixedly connected to the surfaces of the two arc-shaped clamping plates 401 that are far apart from each other.

[0048] Specifically, by inserting the stabilizing rod 403 in the stabilizing component 4 into the soil, the overall stability of the equipment can be increased, and the stabilizing effect can be enhanced during the process of pruning and dwarfing the top of the tulip tree.

[0049] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, the top of the gathering plate 505 is provided with a fixing opening 8, and the top of the sliding plate 512 is slidably connected to the inside of the fixing opening 8.

[0050] Reference Figure 6 As shown, the outer wall of the fixed box 513 is provided with a sliding opening 9, and the T-shaped plate 603 is slidably connected inside the sliding opening 9;

[0051] Reference Figure 1 and Figure 2 As shown, two insecticide tanks 701 are arranged on both sides of the application roller 605, and the insecticide tanks 701 and the cutting blade 515 are arranged in an alternating manner.

[0052] Based on the above preferred embodiments, the working principle of the present invention is as follows:

[0053] In the initial state, the first gathering plate 504 and the second gathering plate 505 are in the maximum distance open state, the second bevel gear 510 and the first bevel gear 509 are in the separated state, the telescopic shaft of the first miniature electric pneumatic rod 508 is in the retracted state, the first compression spring 607 is in the uncompressed state, the tension spring 613 is in the stretched state, the rotating gear 606 and the fixed rack 611 are in the meshing state, the second compression spring 707 is in the uncompressed state, the telescopic shaft of the second miniature electric pneumatic rod 709 is in the extended state, and the L-shaped plate 706 and the fixed arc-shaped protrusion 702 are not in contact.

[0054] During work:

[0055] Workers can place the base plate 1 on one side of the tulip tree, then pull the two curved clamps 401 apart in opposite directions so that they fit on both sides of the tulip tree. This allows the friction pads 402 to be pressed tightly against both sides of the tulip tree, and the bottom of the stabilizing rods 403 to contact the ground soil. Then, workers can step on the pedal 404 to insert multiple stabilizing rods 403 into the ground. Inserting the stabilizing rods 403 into the ground soil increases the overall stability of the equipment and enhances the stabilization effect during the process of pruning and dwarfing the top of the tulip tree.

[0056] After the lifting mechanism inside the support rod 2 raises the fixing plate 3, the first gathering plate 504, and the second gathering plate 505 to the position where the hybrid tulip tree needs to be cut, the staff can electrically control the drive motor 506 and the miniature electric pneumatic rod 508 to start synchronously through the controller. The telescopic shaft of the miniature electric pneumatic rod 508 pushes the bevel gear 509 fixedly connected to it to move to the position of the second bevel gear 510, so that the bevel gear 509 and the second bevel gear 510 are in a meshing state. The start of the drive motor 506 drives the reciprocating screw 507 fixedly connected to it to rotate. The rotation of the reciprocating screw 507 drives the miniature electric pneumatic rod 508 fixedly connected to it to rotate. The rotation of the miniature electric pneumatic rod 508 drives the bevel gear 509 fixedly connected to it to rotate. The rotation of the bevel gear 509 drives the meshing bevel gear 510 to rotate. When the bevel gear 510 rotates, the resistance force generated by the cross shape of the cross groove 511 and the cross rod 502 drives the internal sliding cross rod 502 to rotate synchronously.

[0057] The cross rod 502 rotates inside the movable plate 503. Since the cross rod 502 and the double-acting screw 501 are driven by a belt, the cross rod 502 drives the double-acting screw 501 to rotate synchronously. When the double-acting screw 501 rotates, the double-acting threads on its surface cause the two movable plates 503 to move closer together. The movement of the two movable plates 503 drives the convergence plates 504 and 505, which are fixedly connected to them, to move synchronously, causing the convergence plates 504 and 505 to... 05 moves towards the direction of proximity, and the movement of the moving plate 503 drives the bevel gear 510 connected to it to move synchronously. At this time, the miniature electric pneumatic rod 508 and the bevel gear 509 are rotatably connected inside the gathering plate 505. Thus, when the gathering plate 505 moves with the moving plate 503, the bevel gear 509 and the miniature electric pneumatic rod 508 move synchronously with the gathering plate 505, so that the bevel gear 509 and the bevel gear 510 can maintain a meshed state during the movement.

[0058] As the gathering plates 504 and 505 move towards the center, the hybrid tulip trees located between them are gathered together. Once the hybrid tulip trees are gathered, the controller electrically controls the telescopic shaft of the micro electric pneumatic rod 508 to retract the bevel gear 509 that is fixedly connected to it. The bevel gear 510 stops rotating without any driving force, and the double-acting screw 501 stops synchronously with the cross rod 502. Through the self-locking function of the double-acting screw 501's double-acting thread, the gathering plates 504 and 505 are stably stopped in their positions.

[0059] Then, the continuous rotation of the reciprocating screw 507 causes the slide plate 512 to slide back and forth inside the gathering plate 505. The reciprocating sliding of the slide plate 512 drives the fixed box 513, the cutting drive mechanism 514 and the cutting blade 515, which are fixedly connected to it, to slide back and forth synchronously. When the cutting blade 515 slides back and forth, the cutting drive mechanism 514 is activated to make the cutting blade 515 slide. The reciprocating lateral sliding of the cutting blade 515 can prune and dwarf the top of the gathered hybrid tulip tree. By first gathering and pruning the branches and leaves at the pruning position of the hybrid tulip tree, the overall shape and structure of the tree can be better planned and adjusted, making it more in line with specific landscape design or shaping requirements. This helps to create a more regular, beautiful and unique tree shape.

[0060] Secondly, gathering branches before pruning allows for more precise control over the location and extent of the cut, avoiding the potential negative impacts of arbitrary pruning, such as unnecessary interference with growth. This ensures the pruning operation is just right, achieving the intended purpose while minimizing potential adverse effects on tree growth and health. Furthermore, this method promotes the sprouting and growth of lateral branches, enabling the tree to develop a richer lateral branch system after pruning, increasing the fullness and layering of the crown and further enhancing its ornamental value. Simultaneously, proper gathering before pruning enhances the tree's stability to a certain extent, especially when facing natural environmental factors such as wind and rain, allowing the tree to maintain a relatively stable posture. Gathering branches makes pruning easier, improving efficiency. Gathering branches reduces the area from which they fall during pruning, preventing damage to surrounding people and property. Moreover, by gathering branches before pruning, the top of the branches and leaves can be pruned in one go, avoiding the unevenness of the top branches and leaves caused by multiple prunings, and preventing damage to other parts of the branches and leaves from repeated pruning.

[0061] After the gathered branches and leaves of the tulip tree are cut off, the coating roller 605 and the coating sponge sleeve 609 move along with the cutting to the cut end of the branches and leaves. The protective agent inside the coating roller 605 wets the coating sponge sleeve 609 through the discharge hole 608. The coating sponge sleeve 609, which is soaked with protective agent, rolls at the cut end of the branches and leaves. The compression force of the compression spring 607 drives the slider 602, the rotating shaft 604, the coating roller 605 and the coating sponge sleeve 609 to come into close contact with the cut end of the branches and leaves. Thus, the coating sponge sleeve 609, which is soaked with protective agent, evenly applies the protective agent to the cut end of the branches and leaves, thus protecting the cut branches and leaves.

[0062] The tension force of the tension spring 613 pulls the baffle 612 and the slide rod 610 upward. The upward movement of the slide rod 610 causes the fixed rack 611, which is fixedly connected to it, to move upward. The fixed rack 611 moves upward to engage with the rotating gear 606. When the fixed box 513 moves, it drives the T-shaped plate 603, the rotating shaft 604, the coating roller 605, and the rotating gear 606 to move synchronously. Because the fixed rack 611 is in a limited position, and the rotating gear 606 moves and engages with the fixed rack 611, the fixed rack 611 is in a limited position. The fixed rack 611 causes the rotating gear 606 to rotate under the teeth of the fixed rack 611. The rotation of the rotating gear 606 causes the rotating shaft 604 to rotate as it moves. The rotating shaft 604 rotates as it moves, which in turn causes the coating roller 605, which is fixedly connected to it, to rotate as it moves. By rotating as the coating roller 605 moves, the protective agent soaked in different positions on the coating sponge sleeve 609 can be more evenly applied to the cut end of the branch and leaf at the cut end.

[0063] Applying the protective agent by rotating it during the sliding process to the cut surface of branches and leaves has many important advantages. First, it ensures that the protective agent covers all parts of the cut surface more evenly and comprehensively, avoiding any missed areas. This comprehensive coverage provides broader and more effective protection for the cut surface. Second, rotating the application method helps the protective agent penetrate better into the tiny gaps of the cut surface and into the tissue, thereby enhancing the protective effect and effectively blocking the invasion of adverse external factors, such as pathogens and excessive evaporation of moisture. Third, this meticulous application method helps to form a uniform and stable protective barrier, reducing problems caused by insufficient protection, such as wound infection and drying. Moreover, this careful operation can minimize further damage to the tissue at the cut surface, creating favorable conditions for subsequent healing and recovery. At the same time, rotating the application method allows the protective agent to better adhere to the tissue at the cut surface, increasing adhesion and making the protective effect more durable and reliable.

[0064] After the top of the tulip tree is cut off and dwarfed, the branches and leaves in the middle section are left exposed. When insecticide is sprayed on the tulip tree, the middle section is not effectively sprayed. During the repositioning process after the top is cut off, the lifting mechanism raises the fixed plate 3 and the cutting blade 515 a certain distance. The cut tulip tree is still positioned between the first gathering plate 504 and the second gathering plate 505. During the repositioning process of the cutting blade 515, the activation of the cutting drive mechanism 514 moves the double-layered blades of the cutting blade 515 back and forth. During the movement of the upper cutting blade 515, the operator controls a micro-electric pneumatic device via a controller. The telescopic shaft of rod 709 drives the ear plate 708, which is fixedly connected to it, to retract. The retraction of the ear plate 708 drives the L-shaped plate 706, which is fixedly connected to it, to move synchronously. The L-shaped plate 706 moves to the surface of the fixed arc-shaped protrusion 702. When the upper cutting blade 515 slides back and forth, it drives the fixed arc-shaped protrusion 702, which is fixedly connected to it, to move back and forth synchronously. The movement of the arc-shaped protrusion of the fixed arc-shaped protrusion 702 squeezes the L-shaped plate 706 to slide upward. The upward sliding of the L-shaped plate 706 drives the mounting rod 703, which is slidably connected to it, to slide upward synchronously. The upward sliding of the mounting rod 703 drives the sealing plate 704, which is fixedly connected to it, to slide upward inside the insecticide box 701.

[0065] As the insecticide box 701 slides upwards, it disengages from the atomizing spray plate 705. The insecticide inside the insecticide box 701 then enters the atomizing spray plate 705 through the gap between the insecticide box 701 and the sealing plate 704. The insecticide is then sprayed downwards through the atomizing nozzles inside the atomizing spray plate 705. The reciprocating sliding of the fixed arc-shaped protrusion 702 allows the L-shaped plate 706 to continuously slide up and down, while the sealing plate 704 continuously contacts and disengages from the atomizing spray plate 705. This allows the insecticide inside the insecticide box 701 to be continuously and intermittently sprayed onto the cut branches of the tulip tree. Firstly, this method can continuously and effectively suppress various pests that breed at the cut site. Since the top is relatively vulnerable after dwarfing and easily becomes a target for pests, intermittent spraying of insecticide can promptly control potential pest threats and ensure the healthy growth of new shoots. Firstly, the safety of the pruning points and cut sections is ensured, preventing damage from pests and guaranteeing the normal growth and development of the tulip tree. Secondly, the intermittent spraying pattern can provide sufficient protection during critical periods while avoiding the negative effects of excessive pesticide use, such as pesticide residues and potential harm to the ecological environment. By rationally arranging the spraying interval, the adverse effects of pesticides can be minimized while maximizing their effectiveness. Furthermore, this approach helps maintain a relatively stable growth environment during the special stage after dwarfing, allowing the tulip tree to smoothly reshape its form and recover its growth without pest interference. This promotes better adaptation of the dwarfed tulip tree to its new morphological structure, enhancing its overall vitality and adaptability. Continuous intermittent spraying can also play a certain preventive role in the surrounding environment, reducing the possibility of pests spreading to other plants and achieving a comprehensive control effect within a certain range.
