Description

Technical Field

[0001] This utility model relates to the field of rubber tapping machines, and in particular to a guide rail and a rubber tapping device. Background Technology

[0002] A rubber tapping machine is an automated device used to cut tap lines on the trunk of rubber trees to collect latex. For example, invention patent CN114303871A discloses a rubber tapping machine that is suspended from the trunk by a guide rail ring, which serves as the running track for the tapping device. However, due to the significant differences in trunk diameter and shape among individual rubber trees, existing guide rails mostly adopt a fixed support tooth structure, which is difficult to adapt to different tree shapes. This results in loose fit and insecure fixation, especially in the middle section of the guide rail, where loosening or suspension can easily occur, affecting the stability and cutting accuracy of the tapping process. In addition, to adapt to irregularly shaped trunks, additional guide rail pads are often required for manual adjustment, resulting in a large workload for installation and debugging, low efficiency, and hindering the large-scale application of rubber tapping machines. Utility Model Content

[0003] The purpose of this invention is to provide a guide rail for a rubber tapping device, which solves the problems of existing guide rails being difficult to fix stably on rubber trees and inconvenient to use, so that the guide rail can be stably fixed on rubber trees and is more convenient to use.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a guide rail for a rubber tapping device, comprising a guide rail body arranged around a rubber tree, the guide rail body comprising a first side facing outward and a second side facing the rubber tree, the second side being provided with a plurality of support teeth that abut against the rubber tree, the support teeth being radially floatingly connected to the guide rail body by an elastic element.

[0005] After adopting the above technical solution, this utility model has the following advantages: multiple support teeth are distributed circumferentially along the guide rail to form a multi-point support structure. Each support tooth can be radially floatingly connected to the guide rail body through elastic elements. It can adaptively adjust the contact position and pressure according to the local contour of the tree trunk, which significantly improves the fit and stability between the guide rail and tree trunks of different diameters and irregular shapes, reduces the probability of the middle section of the guide rail becoming loose or suspended, and provides stable support for the rubber tapping device. At the same time, it does not require manual compensation and adjustment based on the guide rail pad, which greatly reduces the workload of installation and debugging, improves the adaptability and deployment efficiency of the rubber tapping robot in complex rubber forest environments, and improves the work efficiency.

[0006] Furthermore, the plurality of support teeth are arranged circumferentially at intervals along the second side surface, and each support tooth is connected to the guide rail body by a separate elastic element.

[0007] By adopting the aforementioned technical solution, since the irregular shapes such as protrusions and depressions on the surface of the tree trunk are often distributed circumferentially, by configuring an independent elastic element for each circumferentially spaced support tooth, each support tooth has an independent radial adjustment degree of freedom, which can respond to the local curvature changes of the tree trunk at the corresponding position. Point-to-point precise fitting can be achieved without mutual restraint, ensuring that multiple contact points are always stably in contact with the tree trunk surface. This significantly improves the circumferential fitting uniformity and support continuity of the guide rail, and avoids the local suspension or stress concentration phenomenon caused by the rigid connection of traditional guide rails as much as possible.

[0008] Furthermore, the second side is provided with a mounting bracket, and the support tooth and the mounting bracket are detachably connected and can slide relative to each other.

[0009] The aforementioned technical solution facilitates the individual replacement and maintenance of the support teeth or allows for adaptive adjustments based on the characteristics of the tree trunk, thereby maximizing the maintainability and flexibility of the guide rail. At the same time, the relative sliding fit between the support teeth and the mounting bracket provides a clear motion guide for its radial floating under the action of the elastic element, ensuring a smooth and reliable floating process as much as possible.

[0010] Furthermore, the mounting bracket is provided with a buckle, the support tooth is provided with a limiting groove, the limiting groove extends along the extension and contraction direction of the elastic element, and the buckle is embedded in the limiting groove and can move along the extension direction of the limiting groove.

[0011] By adopting the aforementioned technical solution, on the one hand, the engagement between the buckle and the limiting groove can be completed without screws, tools or other auxiliary fasteners, making the connection simple and quick. This facilitates the individual replacement, maintenance or adjustment of the support teeth according to the operating conditions, significantly improving the maintainability and assembly efficiency of the guide rail. On the other hand, the limiting groove extends along the expansion and contraction direction of the elastic element, providing a clear guide path for the radial movement of the support teeth. When the buckle slides in the limiting groove, it constrains the lateral displacement of the support teeth, ensuring that they float only in the predetermined direction as much as possible. This avoids movement deviation, jamming or stress concentration as much as possible, ensuring the stability of the elastic floating function.

[0012] Furthermore, the mounting bracket includes at least two limiting ribs for restricting the installation position of the elastic element. The two limiting ribs are spaced apart to form an installation space for accommodating the elastic element. The support tooth is provided with a guide groove that slides with the limiting rib. The limiting rib is provided with a buckle at one end away from the second side. The limiting groove is provided with a stop portion that cooperates with the buckle. When the elastic element is in the maximum elongation position, the stop portion stops the buckle. When the elastic element is in the maximum compression position, the support tooth abuts against the second side.

[0013] Through the above technical solution, the spaced limiting ribs form an installation space to accommodate the elastic element, which realizes reliable axial positioning and spatial constraint of the elastic element. At the same time, the limiting ribs slide with the guide grooves on the support teeth to form a guiding effect, so that the support teeth can stably extend and retract in a predetermined direction. When the elastic element is in the maximum elongation state, the stop part abuts against the buckle to prevent the support teeth from accidentally falling out and ensure assembly reliability. When the elastic element is fully compressed, the support teeth directly abut against the second side of the guide rail body to form a rigid support stop, which avoids structural overload or long-term pressure failure of the elastic element as much as possible, and effectively limits the radial floating stroke range of the support teeth.

[0014] Furthermore, the support tooth is provided with a receiving cavity to accommodate the elastic element, and the elastic element is disposed in both the installation space and the receiving cavity.

[0015] With the above technical solution, the elastic element is simultaneously arranged in the mounting space of the mounting bracket and the receiving cavity of the support tooth, which further avoids displacement, torsion or dislodgement during operation, and further ensures that the support tooth is balanced in force and moves smoothly during radial floating.

[0016] Furthermore, the guide rail body is provided with a first positioning protrusion for positioning one end of the elastic element in the installation space, and a second positioning protrusion for positioning the other end of the elastic element is provided in the receiving cavity of the support tooth, and the two ends of the elastic element are respectively sleeved on the first positioning protrusion and the second positioning protrusion.

[0017] The above technical solution can accurately position the elastic element from both ends, minimizing axial displacement or swaying during repeated expansion and contraction.

[0018] Furthermore, the support tooth has multiple protruding fulcrums on the side facing the resin tree.

[0019] Through the above technical solution, multiple protruding fulcrums transform the contact between the support teeth and the bark from surface contact to dispersed point contact. With the adaptive floating of the elastic element, each fulcrum can independently conform to the slight undulations of the tree trunk surface, adapt to the irregular contours of the local area of ​​the tree trunk, avoid poor fit or stress concentration caused by large-area contact, and reduce the risk of overall slippage caused by environmental factors such as bark dampness and attachments.

[0020] Furthermore, the end of the guide rail body is provided with a connecting part that is fixedly connected to the second side.

[0021] Through the above technical solution, the connecting part, as the force-bearing point for fastening the external structure, provides a clear installation position for the external structure by being fixedly connected to the guide rail body. It can effectively transmit the applied tension force, ensuring that both ends of the guide rail reliably close after wrapping around the tree trunk. It can also effectively transmit and withstand the tension force applied by the cable ties during the locking process, ensuring that both ends of the guide rail reliably close after wrapping around the tree trunk.

[0022] Another objective of this utility model is to disclose a rubber tapping device, which includes a walking component and a cutting component. The walking component includes a guide rail as described in any of the above technical solutions, and a walking frame that cooperates with the guide rail. The walking frame is provided with a driver.

[0023] The above technical solution can independently adjust the contact position and pressure according to the local contour changes of the tree trunk, and maintain effective contact in the protruding or concave areas of the tree trunk. It can automatically adapt to various round, eccentric or irregular tree trunks, and the support teeth form a stable contact with the surface of the tree trunk, ensuring that the device does not shift or loosen during the rubber tapping process. This gives the rubber tapping device both good adaptability and firm fixing performance. Attached Figure Description

[0041] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0042] Example 1:

[0043] like Figures 1 to 9 As shown, the present invention provides a guide rail for a rubber tapping device, including a guide rail body 10 arranged around the rubber tree. The guide rail body 10 includes a first side 11 facing outward and a second side 12 facing the rubber tree. The second side 12 is provided with a plurality of support teeth 14 that abut against the rubber tree. The support teeth 14 are radially floatingly connected to the guide rail body 10 through an elastic member 15.

[0044] Multiple support teeth 14 are distributed circumferentially along the guide rail body 10 to form a multi-point support structure. Each support tooth 14 can be radially floatingly connected to the guide rail body 10 through an elastic element 15. It can adaptively adjust the contact position and pressure according to the local contour of the tree trunk, which significantly improves the fit and stability between the guide rail body 10 and tree trunks of different diameters and irregular shapes. It reduces the probability of the middle section of the guide rail body 10 becoming loose or suspended, providing stable support for the rubber tapping device. At the same time, it eliminates the need for manual compensation and adjustment based on the guide rail pad, greatly reducing the workload of installation and debugging, improving the adaptability and deployment efficiency of the rubber tapping robot in complex rubber forest environments, and improving operational efficiency.

[0045] The first side 11 is provided with a ring tooth 13. The rubber cutting device is also provided with a walking component and a cutting component. The walking component is provided with a walking gear that cooperates with the ring tooth 13. The walking gear is driven by an external force and can move relative to the ring tooth 13 to drive the cutting component to move along the guide rail body 10.

[0046] Since irregular shapes such as protrusions and depressions on the surface of tree trunks are often distributed circumferentially, in this application, multiple support teeth 14 are arranged circumferentially along the second side 12. Each support tooth 14 is connected to the guide rail body 10 through a separate elastic element 15, so that each support tooth 14 has an independent radial adjustment degree of freedom and can respond to the local curvature changes of the tree trunk at the corresponding position. It can achieve precise point-to-point fitting without mutual restraint, and ensure that multiple contact points are always stably in contact with the tree trunk surface. This significantly improves the circumferential fitting uniformity and support continuity of the guide rail body 10, and avoids the local suspension or stress concentration phenomenon caused by the rigid connection of the traditional guide rail body 10 as much as possible.

[0047] Furthermore, the support tooth 14 has multiple raised fulcrums 146 on the side facing the rubber tree. The multiple fulcrums 146 are arranged in a rectangular pattern. The multiple raised fulcrums 146 transform the contact between the support tooth 14 and the bark from surface contact to dispersed point contact. With the adaptive floating of the elastic element 15, each fulcrum 146 can independently conform to the slight undulations of the tree trunk surface, adapt to the irregular contours of the local area of ​​the tree trunk, avoid poor fit or stress concentration caused by large-area contact, and reduce the risk of overall slippage caused by environmental factors such as bark moisture and attachments.

[0048] The second side 12 is provided with a mounting bracket 16. The support tooth 14 and the mounting bracket 16 are detachably connected and can slide relative to each other, which facilitates the individual replacement and maintenance of the support tooth 14 or adaptive adjustment according to the characteristics of the tree trunk. This maximizes the maintainability and flexibility of the guide rail. At the same time, the relative sliding fit between the support tooth 14 and the mounting bracket 16 provides a clear motion guide for its radial floating under the action of the elastic element 15, ensuring that the floating process is as smooth and reliable as possible.

[0049] It should be noted that the second side 12 is provided with multiple mounting brackets 16, and each support tooth 14 is connected by a separate mounting bracket 16 to form an independent floating unit, which facilitates the replacement and maintenance of individual components.

[0050] Specifically, the mounting bracket 16 is provided with a buckle 161, and the support tooth 14 is provided with a limiting groove 142. The limiting groove 142 extends along the extension and retraction direction of the elastic element 15. The buckle 161 is embedded in the limiting groove 142 and can move along the extension direction of the limiting groove 142. On the one hand, the engagement between the buckle 161 and the limiting groove 142 can be completed without screws, tools or other auxiliary fasteners, making the connection simple and quick. This facilitates the individual replacement, maintenance or adjustment of the support tooth 14 according to the working conditions, significantly improving the maintainability and assembly efficiency of the guide rail. On the other hand, the limiting groove 142 extends along the extension and retraction direction of the elastic element 15, providing a clear guide path for the radial movement of the support tooth 14. When the buckle 161 slides in the limiting groove 142, it constrains the lateral displacement of the support tooth 14, ensuring that it floats only in a predetermined direction as much as possible. This avoids movement deviation, jamming or stress concentration as much as possible, ensuring the stability of the elastic floating function.

[0051] To make the movement of the support tooth 14 smoother, the mounting bracket 16 includes at least two limiting ribs 164 for limiting the installation position of the elastic element 15. The two limiting ribs 164 are spaced apart to form an installation space 162 for accommodating the elastic element 15. This achieves reliable limiting and spatial constraint of the axial position of the elastic element 15. At the same time, the support tooth 14 is provided with a guide groove 143 that slides with the limiting rib 164 to form a guiding effect, so that the support tooth 14 can stably extend and retract in a predetermined direction. The limiting rib 164 has a buckle 161 at the end away from the second side 12, and the limiting groove 142 has a stop part 141 that cooperates with the buckle 161. When the elastic member 15 is in the maximum elongation position, the stop part 141 stops the buckle 161 to prevent the support tooth 14 from accidentally coming out and to ensure assembly reliability. When the elastic member 15 is in the maximum compression position, the support tooth 14 abuts against the second side 12 to form a rigid support stop, which avoids structural overload or long-term pressure failure of the elastic member 15 as much as possible and effectively limits the radial floating stroke range of the support tooth 14.

[0052] To further prevent the elastic element 15 from tilting or coming out, in this application, the support tooth 14 is provided with a receiving cavity 144 to accommodate the elastic element 15. The elastic element 15 is simultaneously arranged in the installation space 162 and the receiving cavity 144, which further prevents the elastic element 15 from shifting, twisting or coming out during operation, and further ensures that the support tooth 14 is balanced in force and moves smoothly during radial floating.

[0053] Furthermore, the guide rail body 10 has a first positioning protrusion 163 for positioning one end of the elastic member 15 within the installation space 162, and a second positioning protrusion 145 for positioning the other end of the elastic member 15 within the receiving cavity 144 of the support tooth 14. The two ends of the elastic member 15 are respectively fitted onto the first positioning protrusion 163 and the second positioning protrusion 145. This allows for precise positioning of the elastic member 15 from both ends, minimizing axial displacement or wobbling during repeated extension and retraction.

[0054] It should be noted that the first positioning protrusion 163 and the second positioning protrusion 145 can be cross ribs. The cross rib structure has high compressive strength and deformation resistance. The multiple protruding arms of the cross rib form a multi-point limiting fit with the inner wall of the spring, which significantly enhances the limiting reliability of the elastic element 15 without increasing the assembly complexity.

[0055] It should be noted that the guide rail body 10 has an opening for the glue tree to pass through, so an additional structure is needed to fix the connection between the two ends of the guide rail body 10. Cable ties are usually used. The end of the guide rail body 10 is provided with a connecting part 17 that is fixedly connected to the second side 12. The connecting part 17 serves as the force point for the cable tie to be fastened, and can effectively transmit and bear the tension force applied by the cable tie during the locking process, ensuring that the two ends of the guide rail can be reliably closed after wrapping around the tree trunk.

[0056] During assembly, first, install one end of the elastic element 15 onto the first positioning protrusion 163 in the guide rail body 10. Then, install the second positioning protrusion 145 in the support tooth 14 onto the other end of the elastic element 15. Next, install the support tooth 14 onto the guide rail body 10, wherein the guide groove 143 inside the support tooth 14 corresponds to the limiting rib 164 on the mounting bracket 16, and the snap 161 is inserted into the limiting groove 142. This completes the installation of the support tooth 14 at one installation position on the guide rail body 10. The remaining support teeth 14 can be installed in the same way. After installation, the guide tooth 14 is complete. Figure 1 The state shown.

[0057] When the guide rail is installed on the tree, the fulcrum 146 of the support tooth 14 will press against the tree, the elastic element 15 will be compressed, the cable tie connects the two ends of the guide rail body 10, and then as the cable tie is slowly tightened, the guide rail body 10 contracts, the elastic element 15 continues to be compressed, until the cable tie tightens and the guide rail body 10 is fixed to the tree. At this time, the support tooth 14 on the guide rail body 10 will automatically adjust its position according to the size and shape of the tree under the action of the elastic element 15, so that the fulcrum 146 of the support tooth 14 always remains in contact with the tree.

[0058] Example 2:

[0059] like Figure 10As shown, this embodiment discloses a rubber tapping device, which includes a walking component and a cutting component 30. The walking component includes a guide rail as described in any of the above technical solutions, and a walking frame 20 that cooperates with the guide rail. The walking frame 20 is equipped with a driver. The guide rail can independently adjust the contact position and pressure according to the local contour changes of the tree trunk, and still maintain effective contact in the protruding or concave areas of the tree trunk, thereby automatically adapting to various round, eccentric or irregular tree trunks. The support teeth 14 form a stable contact with the surface of the tree trunk, ensuring that the device does not shift or loosen during the rubber tapping process, so that the rubber tapping device has both good adaptability and firm fixing performance.

[0060] It should be noted that there are two walking components, and the guide rail body 10 has two components. There is a parallel longitudinal slide rail 40 between the two walking components. The cutting component 30 is slidably mounted on the longitudinal slide rail 40 between the two walking components. The cutting component 30 can be a cutter. When the two walking components move synchronously along the circumference of the guide rail body 10, they drive the longitudinal slide rail 40 and the cutter connected to it to run around the tree trunk, so as to realize continuous and stable cutting of the rubber tree.

[0061] In addition to the preferred embodiments described above, there are other embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection claimed by this utility model.
