Description

Technical Field

[0001] This invention relates to the field of pest and disease control technology, and specifically to a lime coating spraying system for pest and disease control. Background Technology

[0002] In the field of forest pest and disease control, applying lime slurry to tree trunks is an important maintenance measure for preventing pests and diseases, preventing sunscald and frost damage, and ensuring the healthy growth of trees. Currently, the application of lime coatings to trees generally involves manual labor using portable spraying equipment carried on the back, with operators holding a spray gun to spray each tree trunk individually. This method has significant shortcomings in practical application: Firstly, coating operations usually involve large areas of forest land or roadside trees, requiring spraying each tree individually. Operators need to carry the equipment for extended periods and continuously perform hand-held spraying actions, resulting in high labor intensity, fatigue, and low work efficiency. Secondly, some tree surfaces have aged dead bark, peeling bark, or impurities, which need to be cleaned before coating to ensure effective adhesion and control of the lime slurry. However, the existing workflow separates cleaning and spraying, further increasing the number of procedures and workload.

This simplifies the operation process, avoids repetitive labor caused by process separation, and thus improves the overall work efficiency.

[0030] 2. By setting a diameter adapter, the present invention enables the system to automatically adapt to trees of different thicknesses, ensuring that the cleaning part can effectively adhere to the irregular bark surface for cleaning; at the same time, since the spraying component is set on the diameter adapter, its distance from the tree body is also adjusted accordingly, ensuring that the nozzle always maintains a suitable spraying distance from the tree body, thereby ensuring the spraying quality and uniformity of the lime coating.

[0031] 3. By setting a fixed component as the operating base point and cooperating with the traction component, the operator can move up and down along the tree trunk on the ground through the rope control system. This transforms the high-intensity and repetitive labor of traditional hand-held spraying into a simple traction operation, reducing labor intensity and making it easier to achieve uniform speed operation, further improving the consistency of spraying effect.

[0034] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings. The described embodiments should not be regarded as limitations on this application. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] Unless otherwise defined, all technical and scientific terms used in the embodiments of this application have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in the embodiments of this application is for the purpose of describing the embodiments of this application only and is not intended to limit the application. The terms "first," "second," "third," "fourth," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein.

[0036] Before providing a further detailed description of the embodiments of this application, some of the nouns and terms involved in the embodiments of this application will be explained. The nouns and terms involved in the embodiments of this application are subject to the following interpretations.

[0037] Cleaning component 1: refers to a device used to pre-treat the bark surface of the tree body 2 before spraying lime coating, such as cleaning old dead bark, peeling bark, moss or attached debris. Its core function is to provide a clean and flat substrate for subsequent lime coating spraying, thereby improving the adhesion of the coating and the effect of pest and disease control.

[0038] Spraying component 3: refers to a device for uniformly and efficiently spraying lime slurry, pesticides or other pest control liquids onto the surface of the tree body 2. In the embodiments of this application, this component is usually integrated with the cleaning component 1 and can automatically adjust the spraying distance according to the diameter of the tree to ensure the uniformity of the coating thickness.

[0039] Diameter adapter: This refers to the mechanism installed inside the cleaning component 1, which can automatically or semi-automatically adjust according to the diameter of the tree body 2 of different thicknesses. Its main function is to ensure that the cleaning part can fit tightly against the tree surface, and at the same time, adjust the distance between the spraying component 3 and the tree surface to achieve universal operation for targets of different sizes.

[0040] Cleaning section: refers to the specific working part of the cleaning component 1 that directly contacts the surface of the tree body 2 and performs cleaning actions such as scraping and sweeping. The design of this part directly affects the cleaning quality of the bark surface. In some embodiments, it can be composed of a hard brush, scraper, or wear-resistant strip.

[0041] Fixed component 22: refers to a device that is detachably installed on the tree body 2 to provide a stable operating reference point or guide rail for the entire spraying system. Its presence enables the cleaning component 1 and the spraying component 3 to move stably and accurately along the axis of the tree, which is especially suitable for scenarios where segmented operations are performed on taller tree trunks.

[0042] Traction component: refers to an auxiliary mechanism used to control the lifting or moving of cleaning component 1 and spraying component 3 along the axis of tree body 2. Through this component, the operator can control the movement of the work module with less effort and at a uniform speed, realizing an automated or semi-automated work process, thereby reducing labor intensity and improving work efficiency.

[0043] Please see Figures 1 to 4 This application aims to provide a lime coating spraying system for pest and disease control. This system aims to solve the technical problems of high labor intensity and low efficiency in the existing tree whitewashing operation, as well as the cumbersome operation and poor coating adhesion caused by the separation of cleaning and spraying processes. This application integrates the two steps of bark cleaning and lime spraying into the same operation process through an integrated design, and achieves adaptive adjustment for trees of different thicknesses through a specific mechanical structure, thereby improving the automation level of the operation and the coating quality.

[0044] This application provides a lime coating spraying system for pest and disease control. Its core components include a cleaning component 1 and a spraying component 3. The cleaning component 1 is designed to move along the axis of the tree body 2, i.e., in the vertical direction. This design aims to achieve continuous operation on the tree trunk from bottom to top or from top to bottom, avoiding the tedious manual adjustment of position. Through this axial movement, the entire trunk within a predetermined height range can be treated in one operation, improving the efficiency of working on a single tree.

[0045] The cleaning component 1 has a cleaning space inside to accommodate the tree body 2. This component includes a cleaning section and a diameter adapter section. The cleaning section directly contacts the surface of the tree body 2 and performs physical cleaning functions, such as cleaning old bark. The diameter adapter section is an adjustable support structure on which the cleaning section is mounted. This design allows the specific position and orientation of the cleaning section to be controlled by the diameter adapter section.

[0046] A key feature of this system is that at least a portion of the diameter adapter is designed to move within the cleaning space along the radial direction of the tree body 2, either towards or away from the tree's center. This radial mobility allows the system to adapt to different tree diameters. When facing a thicker tree, the diameter adapter expands outward; when facing a thinner tree, it contracts inward. In this way, the system can automatically or manually adapt to the tree's diameter and drive the cleaning part to maintain close contact with the surface of the tree body 2, ensuring effective cleaning regardless of the trunk's thickness and solving the problem of poor applicability of existing equipment.

[0047] Furthermore, the spraying component 3 is mounted on the diameter adapter, meaning that the position of the spraying component 3 changes with the radial movement of the diameter adapter. When the diameter adapter changes its radial position to accommodate tree bodies 2 of different diameters, it simultaneously moves the spraying component 3 fixed on it. This design aims to automatically adjust the distance between the spraying component 3 and the tree body 2. For example, when processing a thick tree, the diameter adapter expands outward, and the spraying component 3 also moves outward, maintaining a preset and suitable spraying distance with the expanded tree surface. Conversely, the same applies. Through this mechanical linkage, a constant spraying distance can be ensured without additional adjustments, thereby ensuring the uniformity and quality of the lime coating and avoiding problems of excessive thickness or thinness caused by distance changes.

[0048] In a preferred embodiment, to concretize the above functional concept, please refer to [link to relevant documentation]. Figure 2 and Figure 3 The structure of the cleaning component 1 can be further refined. The diameter fitting part can be composed of a first arc plate 4 and a second arc plate 5 forming the main frame. The first arc plate 4 and the second arc plate 5 extend along a preset arc and are arranged opposite to each other. They are rotatably connected by one or more first hinges 15. This design allows the first arc plate 4 and the second arc plate 5 to open and close like a clam shell, making it convenient to fit the entire device onto the tree body 2. After closing, the first arc plate 4 and the second arc plate 5 together form a roughly circular cleaning space to accommodate the tree body 2.

[0049] In this embodiment, in order to achieve radial adjustment, the diameter adapter also includes a movable first adjustment block 6 and a second adjustment block 7. The first adjustment block 6 is mounted on the first arc plate 4 and can slide on it in the radial direction of the tree body 2.

[0050] Similarly, the second adjusting block 7 is mounted on the second arc-shaped plate 5 and is positioned opposite to the first adjusting block 6, allowing for radial sliding. This structure decouples the overall opening and closing action from the local radial fine-tuning action, making the structure more stable and reliable. By controlling the radial position of these adjusting blocks, the local contour of the tree trunk surface can be precisely adapted.

[0051] Simultaneously, the cleaning section is also specifically defined as a first cleaning component 8 and a second cleaning component 9. The first cleaning component 8 is located on the side of the first adjusting block 6 facing the tree body 2, while the second cleaning component 9 is located inside the second adjusting block 7. When the first adjusting block 6 and the second adjusting block 7 move inward, they drive the first cleaning component 8 and the second cleaning component 9 to abut against the surface of the tree body 2. These cleaning components can be designed as brushes, scrapers, or wear-resistant blocks with a certain degree of hardness and toughness, used to effectively scrape off the attachments on the bark when the system moves along the trunk. Through this structure, the abstract "cleaning section" and "diameter adaptation section" are grounded in concrete and achievable mechanical components, enhancing the feasibility of the solution.

[0052] Furthermore, in a preferred embodiment, to ensure that the adjusting block can continuously and stably apply pressure to the tree surface and ensure the cleaning effect, please refer to [link to relevant documentation]. Figure 2 The cleaning component 1 may further include a first elastic element 10, which can be a highly elastic steel wire rope, spring, or rubber band, wrapped around the outer frame composed of the first arc-shaped plate 4 and the second arc-shaped plate 5. Its key function is that it abuts against the outer ends of all the first adjusting blocks 6 and the second adjusting blocks 7 away from the tree body 2. Through the contraction force of the first elastic element 10 itself, all adjusting blocks can be continuously pushed inwards, i.e., towards the tree body 2. This solves the problem that the cleaning component may detach from the bark due to the unevenness of the tree trunk surface, achieving contour-fitting cleaning of the bark surface. This elastic pressure ensures that the first cleaning component 8 and the second cleaning component 9 always apply appropriate pressure to the tree surface, thereby achieving efficient and thorough cleaning.

[0053] To facilitate installation and adjustment of the tension of the first elastic member 10, its two ends are designed to be detachably connected. Specifically, it may include a tensioning mechanism consisting of a first adjusting plate 11, a second adjusting plate 12, a first adjusting bolt 13, and a first adjusting nut 14. The two ends of the first elastic member 10 are respectively connected to the first adjusting plate 11 and the second adjusting plate 12. The first adjusting bolt 13 passes through these two adjusting plates. By rotating the first adjusting nut 14, the distance between the two first adjusting plates 11 and the second adjusting plate 12 can be changed, thereby easily tightening or loosening the first elastic member 10 to adapt to the needs of different tree species or cleaning forces. To ensure that the first elastic member 10 remains stable during movement, annular grooves can be opened on the first arc-shaped plate 4 and the second arc-shaped plate 5, and limiting grooves can be opened on the first adjusting block 6 and the second adjusting block 7 to accommodate the first elastic member 10 within these grooves and prevent it from slipping out. In addition, the first adjusting block 6 and the second adjusting block 7 are designed as wedge-shaped structures with smaller inner end cross-sections, which facilitates smoother insertion and sliding on the bark surface.

[0054] In another preferred embodiment, please refer to Figure 2 and Figure 3 The structure of the spraying assembly 3 is specified. The spraying assembly 3 may include a first annular pipe 16 and a second annular pipe 18 arranged along the circumference of the tree. The first annular pipe 16 is directly fixed to the first adjusting block 6, while the second annular pipe 18 is fixed to the second adjusting block 7. This arrangement is key to achieving adaptive adjustment of the spraying distance, because the positions of the first adjusting block 6 and the second adjusting block 7 change with the diameter of the tree, so the first annular pipe 16 and the second annular pipe 18 fixed to them naturally move accordingly, thereby achieving distance linkage with the tree surface.

[0055] To achieve 360-degree spraying without blind spots, at least two nozzles, namely the first nozzle 17 and the second nozzle 19, are detachably installed on both the first annular pipe 16 and the second annular pipe 18. These nozzles are all directed towards the tree trunk 2 at the center of the cleaning space, ensuring that the lime slurry sprayed from all angles can evenly cover the trunk. The detachable design also facilitates the replacement of nozzles with different orifice diameters or fan-shaped angles according to the paint viscosity or spraying requirements. For liquid supply, the first inlet pipe 20 and the second inlet pipe 21 are connected to the first annular pipe 16 and the second annular pipe 18 respectively, and are connected to an external liquid supply pump. This design translates the abstract spraying function into a concrete array of pipes and nozzles, achieving a highly efficient and uniform annular spraying effect.

[0056] Furthermore, to improve the stability and automation of the operation, please refer to [link / reference needed]. Figure 1The system may also include a fixing component 22. This fixing component 22 is pre-installed above the cleaning component 1 and securely fixed to the tree body 2 during use. Its main function is to provide a stable reference and support for subsequent cleaning and spraying operations. The cleaning component 1 and the fixing component 22 are detachably connected, for example, through a flexible suspension connection via a third elastic member 33 and a fourth elastic member 34. This design allows the cleaning component 1 to move smoothly axially relative to the fixed fixing component 22, avoiding shaking and uneven speed caused by hand-held or unguided movement, thus ensuring the quality of cleaning and spraying. This is particularly important for treating the lower half of tall trees, solving the problem of maintaining stable operation in traditional methods.

[0057] In one alternative embodiment, the structure of the fixing component 22 is described in detail; please refer to [link to relevant documentation]. Figure 3 Its structure is similar to the diameter adapter of the cleaning component 1, also including an openable third arc plate 23 and a fourth arc plate 24, and a third adjusting block 25 and a fourth adjusting block 26 that can slide radially on the third arc plate 23 and the fourth arc plate 24. By moving the third adjusting block 25 and the fourth adjusting block 26 inward so that they are pressed tightly against the tree body 2, sufficient friction can be generated to lock the fixing component 22 at a specified height on the tree trunk. In order to increase friction and protect the bark, multiple flexible pads can also be provided on the inner side of the third arc plate 23 and the fourth arc plate 24.

[0058] In one alternative embodiment, the flexible pad near the tree body 2 can be designed with a sloping surface. This sloping arrangement allows the flexible pad to better conform to the tree surface when the fixing component 22 clamps the trunk, especially when the trunk surface is irregular. This increases the contact area, provides more uniform support and greater friction, thus making the fixing effect of the fixing component 22 more stable and reliable. An advantage of this structure is that it also has diameter adaptability, allowing it to be securely installed on trees of various thicknesses.

[0059] To make the installation of fixing component 22 easier and more reliable, please refer to... Figure 2 and Figure 3Furthermore, it can be equipped with a spring-loaded locking mechanism similar to that of the cleaning component 1. Specifically, a second spring-loaded element 27 can be set to surround the third arc-shaped plate 23 and the fourth arc-shaped plate 24, and its contraction force continuously presses the third adjusting block 25 and the fourth adjusting block 26 inward, so that they abut against the tree body 2. Similarly, the tension of the second spring-loaded element 27 can be adjusted by a mechanism consisting of the third adjusting plate 28, the fourth adjusting plate 29, the second adjusting bolt 30, and the second adjusting nut 31. The third arc-shaped plate 23 and the fourth arc-shaped plate 24 are connected by the second hinge 32 for easy opening and closing. This design makes the installation process of the fixing component 22 faster, and the clamping force more uniform and reliable, avoiding stress concentration or loosening problems that may be caused by single-point bolt tightening.

[0060] In a more preferred embodiment, for automated or semi-automated lifting of the entire system, please refer to [link to relevant documentation]. Figure 1 and Figure 4 The system can also be equipped with a traction component. This traction component works in conjunction with the fixing component 22 to control the vertical movement of the cleaning component 1 and the spraying component 3.

[0061] Specifically, two lifting rings 36 can be installed on the cleaning component 1, while two corresponding guide wheels 37 can be installed on the fixing component 22 or the ground base. A first pull rope 38 and a second pull rope 39 are used, with one end connected to the lifting rings 36 and the other end passing over the guide wheels 37 and controlled by the operator or a motor. This design utilizes pulleys to change the direction of force, allowing the operator to easily and smoothly pull the cleaning component 1 up and down along the tree trunk on the ground. This reduces the operator's labor intensity, especially for high-altitude operations, eliminating the need for climbing and ensuring safety. Simultaneously, the uniform traction helps ensure the consistency of the coating thickness. Furthermore, the third elastic element 3... The cleaning component 1 and the spraying component 3 are elastically suspended and connected. When the force pulling the first pull rope 38 and the second pull rope 39 gradually decreases, the cleaning component 1 and the spraying component 3 can be reset under the action of the third elastic component 33 and the fourth elastic component 34. The reset speed is controlled by the force pulling the first pull rope 38 and the second pull rope 39. In order to prevent the cleaning component 1 from affecting the coating when it resets, a soft brush is provided on the other side of the first cleaning component 8 and the second cleaning component 9. That is, when it moves downward, it cleans the tree body. When it moves upward, it re-coats the coating with the soft brush to prevent uneven coating in some areas.

[0062] In an optional embodiment, to further enhance the portability of the cleaning component 1 and the fixing component 22, a first insertion post 35 and a second insertion post are also included. The first insertion post 35 and the second insertion post are respectively fixedly connected to the first arc plate 4 and the second arc plate 5. Correspondingly, on the side of the third arc plate 23 and the fourth arc plate 24 near the cleaning component 1, a first insertion hole and a second insertion hole are respectively provided to cooperate with the first insertion post 35 and the second insertion post. By inserting the insertion post into the corresponding insertion hole, it can be ensured that the two components will not rotate or shift relative to each other during transportation, which facilitates the transfer or carrying of the two components. When it is necessary to fix the two components to the tree body 2, the first insertion post 35 and the second insertion post need to be pulled out from the first insertion hole and the second insertion hole.

[0063] Furthermore, in order to increase the tightness of the connection and reduce wear, a layer of friction material, such as rubber or polyurethane, can be coated on the surface of the first plug post 35 and the second plug post. This friction material can not only provide additional friction to prevent components from accidentally disengaging, but also play a certain role in buffering, making the operation of the entire system more stable.

[0064] To constitute a complete, independently operating system, please refer to the relevant claims and background description. This system should also include a lime slurry storage and delivery section. Specifically, it may include a storage tank and a delivery pump. The input end of the delivery pump is connected to the storage tank for drawing lime slurry, and its output end is connected via pipelines, such as the first inlet pipe 20 and the second inlet pipe 21, to the first annular pipe 16 and the second annular pipe 18 of the spraying assembly 3.

[0065] In one application scenario, the storage tank can be designed as a backpack type, where the operator carries the storage tank and infusion pump on their back and holds a traction rope to carry out the operation. This type of operation is highly flexible and suitable for orchards with complex terrain or scattered trees.

[0066] In another application scenario, the cleaning component 1, the spraying component 3, and the fixing component 22 can be pre-installed on the tree body 2. During operation, simply connect the external liquid supply line to the first liquid inlet pipe 20 and the second liquid inlet pipe 21, and then pull the traction rope to complete the spraying.

[0067] In another application scenario, for large-scale, standardized operations, such as whitewashing roadside trees, the storage tank, infusion pump, and multiple pre-assembled cleaning / fixing components can be placed on a transport vehicle to achieve more efficient collaborative operations.

[0068] Hooks can also be installed on the liquid storage tank for convenient storage and placement of cleaning component 1 and fixing component 22 when not in operation.

[0069] The specific product form of a lime coating spraying system for pest and disease control provided in this application will be described below with reference to the accompanying drawings. Figure 1 As shown, in practical applications, the system mainly consists of a fixing component 22 installed on the upper part of the tree body 2 and an integrated cleaning and spraying module suspended below it. This integrated module includes a cleaning component 1 and a spraying component 3. The fixing component 22 firmly holds the tree trunk through its internal clamping mechanisms such as the third adjusting block 25, the fourth adjusting block 26, and the second elastic member 27, providing a stable anchor point. The cleaning component 1 is connected to the fixing component 22 through elastic connectors such as the third elastic member 33 and the fourth elastic member 34, maintaining a certain degree of relative mobility.

[0070] Within cleanup component 1, such as Figure 2 and Figure 3 As shown, an openable frame is formed by a first arc-shaped plate 4 and a second arc-shaped plate 5. Inside the frame, multiple first adjusting blocks 6 and second adjusting blocks 7 slide radially. On the inner side of these adjusting blocks are first cleaning components 8 and second cleaning components 9, such as a wire brush and a soft brush, serving as cleaning parts. The wire brush is located below the soft brush, and the outer side is clamped by a first elastic component 10, ensuring that the inner cleaning components adhere closely to the bark. The specific structure of the spraying assembly 3, namely the first annular pipe 16, the second annular pipe 18, and multiple first nozzles 17 and second nozzles 19 thereon, is directly mounted on these movable first adjusting blocks 6 and second adjusting blocks 7. This integrated design allows the distance between the nozzles and the tree to be adjusted synchronously as the adjusting blocks adapt to changes in tree diameter, achieving a linkage and adaptive mechanism between cleaning adhesion and spraying distance.

[0071] like Figure 4 As shown, to control the lifting and lowering of the system, the operator can use a traction assembly. Pulling the first pull rope 38 and the second pull rope 39, the pulling force is redirected through the guide wheel 37 fixed to the ground or the fixed assembly 22, acting on the lifting ring 36 on the cleaning assembly 1, thereby smoothly pulling the integrated cleaning and spraying module downwards along the tree trunk. During the downward pull, the first cleaning component 8 and the second cleaning component 9 located above first scrape off the old bark and debris on the surface of the tree trunk. Immediately afterwards, the first nozzle 17 and the second nozzle 19 located below immediately spray lime slurry onto the cleaned surface. The lime slurry is continuously supplied by an external infusion pump through the first inlet pipe 20 and the second inlet pipe 21. The entire process can be completed continuously, realizing the synchronous operation of cleaning and spraying, and improving efficiency.

[0072] This embodiment provides a specific example integrating most of the preferred technical features of this application, aiming to demonstrate the corresponding technical effects that can be achieved when the various components work together. Its complete workflow is as follows: First, the operator selects a tree trunk 2 to be worked on, and adjusts the opening and closing degree of the fixing component 22 according to its approximate thickness. By opening the second hinge 32, the fixing component 22, composed of the third arc-shaped plate 23 and the fourth arc-shaped plate 24, is fitted onto the tree trunk at the predetermined highest working height, and then closed. At this time, the second adjusting nut 31 is tightened, and the tension second elastic member 27 is tightened, causing it to drive the third adjusting block 25 and the fourth adjusting block 26 to press tightly against the bark, completing the installation of the fixing component 22.

[0073] The second step involves attaching the integrated module, which combines the cleaning component 1 and the spraying component 3, to the fixed component 22. Specifically, if the cleaning component 1 and the fixed component 22 are connected via the plug-in post 35 (for transportation or storage), they are first separated. Then, the cleaning component 1 is suspended below the fixed component 22 via the third elastic member 33 and the fourth elastic member 34. Finally, the first inlet pipe 20 and the second inlet pipe 21 of the infusion line from the backpack liquid storage tank or the infusion pump on the transport vehicle are connected to the quick connector on the integrated module.

[0074] The third step is to open the first hinge 15 of the cleaning component 1, wrap it around the tree body 2 and close it, tighten the first adjusting nut 14 to tighten the first elastic element 10, drive the first adjusting block 6 and the second adjusting block 7 to move inward until the first cleaning element 8 and the second cleaning element 9 on them are completely pressed against the bark surface like a hard brush. At this time, the first annular pipe 16, the second annular pipe 18 and the first nozzle 17 and the second nozzle 19 installed on the adjusting block are also automatically positioned at a suitable spraying distance from the bark surface.

[0075] The fourth step involves starting the infusion pump, which delivers lime slurry into the first annular pipeline 16 and the second annular pipeline 18. The system then enters standby mode. The operator holds the first pull rope 38 and the second pull rope 39 of the traction assembly and slowly and evenly pulls them downwards. Under the combined action of gravity and tension, the integrated module begins to slide smoothly downwards along the tree trunk. During the sliding process, the first cleaning component 8 and the second cleaning component 9 located at the top scrape and clean the bark, removing all attached materials.

[0076] Fifth step: Following the first cleaning component 8 and the second cleaning component 9, the cleaned bark surface immediately enters the spray range of the first nozzle 17 and the second nozzle 19. Atomized lime slurry from multiple nozzles covers the tree trunk in a uniform fan-shaped cross pattern, instantly forming a uniform and firmly adhered white coating. Since cleaning and spraying occur almost simultaneously, the possibility of the surface being re-contaminated after cleaning is avoided, and the adhesion of the coating is enhanced. The operator continues to pull down at a uniform speed until the integrated module reaches the predetermined lowest position, and then stops the infusion pump and traction to complete the operation of a single tree.

[0077] This embodiment organically combines all the aforementioned technical features to achieve the following technical effects: First, by integrating cleaning and spraying into a single process, the two steps are combined, significantly improving work efficiency compared to traditional step-by-step operations. Second, the combination of the diameter adapter and the elastic component enables adaptive cleaning of trees of varying thicknesses and surface smoothness, ensuring cleaning quality. Third, the mechanical linkage between the spraying component and the diameter adapter allows for automatic adjustment of the spraying distance, ensuring uniform coating thickness. Finally, the cooperation between the fixing and traction components enables semi-automated, labor-saving operation, significantly reducing labor intensity and improving operational safety and stability. In summary, the synergistic effect of these technical features makes this system highly efficient, high-quality, low-labor-intensity, and widely applicable in pest and disease control operations.
