Description

Technical Field

[0001] This invention relates to the field of rubber tapping machines, and in particular to a rubber tapping machine and a rubber tapping method. Background Technology

[0002] In natural rubber tapping operations, automated tapping machines can significantly improve efficiency and reduce reliance on manual labor. In existing technologies, some tapping machines employ a dual-motor system to achieve fully automated tapping. For example, the tapping machine disclosed in Chinese invention patent application CN111972251A uses one motor to drive the entire machine to move back and forth along the tree trunk, while another motor independently controls the cutting mechanism to perform the tapping action. Although this structure achieves functional separation, it suffers from drawbacks such as high energy consumption, high cost, and complex control systems, making it unsuitable for widespread application in rubber-growing areas with limited power supply. To simplify the drive system, some solutions have attempted to use single-motor integrated control, as shown in Chinese invention patent CN114680016A, which distributes the power of a single motor to the walking and cutting mechanisms through a complex gear transmission chain. However, this solution relies on a large number of precision gears for power distribution and state switching, resulting in a bulky overall structure, extremely high assembly precision requirements, poor operational stability, and a tendency for motion interference or response lag during the coordinated walking and cutting actions, affecting tapping quality and equipment reliability. Summary of the Invention

[0003] The purpose of this invention is to provide a rubber tapping machine that solves the problem of complex structure in the prior art and achieves single-motor control using a simpler structure.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a rubber tapping machine, comprising a walking assembly, a cutting assembly, and a coupling transmission unit. The walking assembly includes a guide rail and a walking frame that slides with the guide rail. The walking frame is equipped with a driver. The coupling transmission unit includes a first transmission component, a second transmission component, and a longitudinal transmission component. The first transmission component is drivenly connected to the driver. The longitudinal transmission component is connected between the first transmission component and the cutting assembly. The second transmission component is disposed on the guide rail and has a free-spinning state that is rotatable relative to the guide rail and a locked state that forms a fixed engagement with the guide rail. In the free-spinning state, the first transmission component and the second transmission component drive and rotate synchronously, and the walking frame is stationary relative to the guide rail. The cutting assembly is raised and lowered via the longitudinal transmission component. In the locked state, the first transmission component rotates relative to the second transmission component. While the walking frame moves along the guide rail, the cutting assembly is raised and lowered via the longitudinal transmission component.

[0005] By adopting the above technical solution, the present invention has the following advantages: Utilizing the cooperative relationship between the first transmission component, the second transmission component, and the longitudinal transmission component, the orderly switching and coordinated operation of walking and cutting actions are achieved under the drive of a single driver, eliminating the need for multiple independent power sources and significantly simplifying the overall structure and control system of the equipment. When the second transmission component is in an idling state, it is not fixedly connected to the guide rail. The first transmission component drives the second transmission component to rotate synchronously, and the power is transmitted to the cutting component via the longitudinal transmission component, enabling it to complete the lifting and cutting action, while the walking frame remains stationary due to the lack of relative driving force. When the second transmission component switches to the locked state and forms a fixed cooperation with the guide rail, the first transmission component rotates relative to the second transmission component. At this time, part of the power reacts to the guide rail through the second transmission component, pushing the walking frame to move along the guide rail, while the other part still drives the cutting component to lift and lower synchronously through the longitudinal transmission component. The switching between the two working states is achieved through the mechanical cooperation between the second transmission component and the guide rail, eliminating the need for complex electronic control algorithms and making the operation process simpler and more reliable.

[0006] Furthermore, the guide rail is provided with a first position and a second position distributed along its extension direction. The first position and the second position are respectively provided with a second transmission member. When the first transmission member is at the first position, the cutting component moves up and down along a first direction. When the first transmission member is at the second position, the cutting component moves up and down along a second direction. The first direction is opposite to the second direction.

[0007] By adopting the aforementioned technical solution, a single driver is used in conjunction with lifting actions in opposite directions to achieve reciprocating coverage of the rubber cutting path while maintaining single-motor drive.

[0008] Furthermore, the second transmission member is provided with a mating protrusion, and the guide rail is provided with a guide groove extending along the rotation direction of the second transmission member. The mating protrusion extends into the guide groove, and the second transmission member is elastically loaded so that the mating protrusion abuts against the first end of the guide groove in a free state. A rotational gap is provided between the mating protrusion and the second end of the guide groove. When the second transmission member is driven to rotate by the first transmission member until the mating protrusion abuts against the second end of the guide groove, the second transmission member and the guide rail form a fixed fit.

[0009] Using the aforementioned technical solution, the rotation gap reserved in the guide groove provides the necessary motion tolerance for the transmission process, ensuring smooth rotation in the idling state and reliable locking through the rigid contact between the protrusion and the end face of the groove when reaching the set position, effectively transmitting the reaction force required for walking. Relying only on the motion relationship and elastic preload of the mechanical structure itself, the second transmission component can switch between idling and locking states without the need for additional sensors, electromagnetic devices or complex control logic.

[0010] Furthermore, the cutting assembly includes a blade holder and a blade head detachable from the blade holder, the blade head being a male blade or a female blade. When the first transmission member is in a first position, the cutting assembly has a first lifting stroke, and when the first transmission member is in a second position, the cutting assembly has a second lifting stroke. The first lifting stroke and the second lifting stroke are not equal.

[0011] The above technical solution supports flexible replacement of male or female blades. At the same time, by combining the unequal first and second lifting strokes at the first and second positions, the rubber tapper can adaptively adjust the cutting depth and range of motion according to the blade type and working direction.

[0012] Furthermore, the lengths of the rotational gaps corresponding to the two second transmission components along the rotational direction of the second transmission component are different.

[0013] The above technical solution enables the rubber tapping machine to automatically match the lifting characteristics required by the corresponding blade type without adjusting the transmission structure or control logic, simply by changing the blade head.

[0014] Furthermore, the extension lengths of the rotational gaps corresponding to the two second transmission members are the same, and the lengths of the mating protrusions of the two second transmission members along the rotational direction of the second transmission members are different.

[0015] Through the above technical solution, since the mating protrusion extends into the guide groove, its length directly determines the range of angles that can be freely rotated within the guide groove's idle stroke: the longer the mating protrusion, the smaller the idle angle that can be rotated within the same length of rotational gap; conversely, the shorter the mating protrusion, the larger the idle angle. The lifting stroke of the cutting assembly is determined by the angle rotated by the first transmission component driving the second transmission component during the idle phase. This mechanical design, which adjusts the length of the mating protrusion to control the idle stroke, does not require changing the guide groove structure. After replacing the cutter head, its stroke characteristics can be adapted simply by changing the mating protrusion. When the upward movement at the first position is greater than the downward movement at the second position, the net feed direction is upward, adapting to the bottom-up cutting mode required by the female cutter; conversely, when the downward movement is greater than the upward movement, the net feed direction is downward, adapting to the top-down cutting mode required by the male cutter.

[0016] Furthermore, the first transmission component is a gear set, the guide rail is provided with teeth, the second transmission component is an output gear detachably mounted on the guide rail, the gear set includes a first gear part for meshing with the teeth and a second gear part for meshing with the output gear, the first gear part and the second gear part are coaxially arranged and fixedly connected by fasteners.

[0017] Through the above technical solution, the second transmission component adopts a detachable output gear, which makes it easy to replace the output gear with different mating protrusion lengths according to the usage requirements of the male or female blade, thereby adjusting the idle angle and lifting sequence without modifying the main transmission structure.

[0018] Furthermore, the cutting assembly includes a housing and a blade holder rotatably mounted on the housing. The housing is connected to the first transmission member via the longitudinal transmission member. The blade holder has a cutting state away from the housing and a retracted state close to the housing. The coupling transmission unit further includes a third transmission member and a fourth transmission member. The third transmission member is connected to the first transmission member, and the fourth transmission member is connected to the blade holder via a transmission shaft. When the second transmission member is in an idling state, the third and fourth transmission members engage to drive the fourth transmission member, causing the blade holder to switch between the cutting state and the retracted state. When the second transmission member is in a locked state, the third and fourth transmission members disengage, and the blade holder maintains its current state.

[0019] With the above technical solution, the switching of the tool holder only occurs in the idle state, which minimizes the risk of uneven cuts or bark damage caused by unexpected movement of the tool holder during rubber tapping. At the same time, the switching of the state is completed automatically by the coupling and disengagement of the mechanical transmission, which is simpler and more reliable.

[0020] Furthermore, the fourth transmission component includes a sector gear, a first one-way transmission component, and a second one-way transmission component arranged coaxially. The fourth transmission component has a first state in which the sector gear engages with the third transmission component when rotated in a first direction, and a second state in which the sector gear disengages from the third transmission component when rotated in a second direction. In the first state, the third transmission component drives the fourth transmission component to rotate towards the second state through the first one-way transmission component. In the second state, the third transmission component drives the fourth transmission component to rotate towards the first state through the second one-way transmission component.

[0021] With the above technical solution, relying solely on a single continuously rotating drive source, the reciprocating oscillation of the fourth transmission component can be automatically achieved through the direction selection function of two unidirectional transmission components, thereby realizing the switching of the tool holder state.

[0022] Furthermore, the walking frame also includes a battery assembly electrically connected to the drive unit. The walking frame has a battery compartment for installing the battery assembly. The battery compartment forms an opening on one side of the walking frame opposite the guide rail. The walking frame also includes a cover for closing the opening. The cover is threadedly connected to the opening, and a sealing ring is provided between the cover and the inner wall of the opening.

[0023] The above technical solution involves installing the battery assembly in the battery compartment on the side of the guide rail opposite the walking frame. This avoids interference from the battery compartment with the sliding fit of the guide rail and the rubber tapping work space, and also allows operators to directly access the battery area from the outside of the equipment, improving maintenance accessibility. The battery compartment opening is sealed with a threaded cover. The threaded structure can be quickly tightened or loosened by hand, significantly simplifying battery replacement and daily maintenance procedures. Simultaneously, a sealing ring is installed between the cover and the inner wall of the opening. Combined with the uniform clamping force provided by the threaded connection, the sealing ring can stably fit the contact surface, forming a reliable static seal. The thread itself also has a certain labyrinth barrier effect. Together, these two elements constitute a double sealing mechanism, preventing rainwater, latex, moisture, and dust from entering the battery compartment as much as possible, ensuring the long-term safe operation of the battery in the high-humidity and polluted outdoor environment of rubber plantations.

[0024] Another object of the present invention is to provide a rubber tapping method, wherein the rubber tapping machine adopts any of the above-described technical solutions, the cutting component includes a housing and a blade holder rotatably disposed on the housing, the housing is connected to the first transmission member via the longitudinal transmission member, and the blade holder has a cutting state away from the housing and a retracted state close to the housing. The rubber tapping method of the rubber tapping machine is as follows:

[0025] S1. Installation: Select a male or female blade according to the rubber tapping requirements, and install the selected blade head onto the blade holder. At the same time, adjust the length of the rotation clearance along the rotation direction of the second transmission component, or select a second transmission component with a matching protrusion of different lengths to match the selected blade head.

[0026] S2, Fixing: The walking component is fixed to the tree body via guide rails;

[0027] S3. Blade placement: The driver drives the longitudinal transmission component through the first transmission component to move the blade holder to the cutting state and complete the blade placement action. At the same time, the first transmission component and the second transmission component are in transmission cooperation and rotate synchronously. The walking frame is stationary relative to the guide rail, and the cutting assembly is raised and lowered through the longitudinal transmission component.

[0028] S4. Cutting: The first transmission component rotates relative to the second transmission component. While the walking frame moves along the guide rail, the cutting assembly is raised and lowered through the longitudinal transmission component, so that the blade holder cuts a spiral line on the tree.

[0029] S5, Retracting the blade: After cutting is completed, the driver drives the longitudinal transmission component in the opposite direction through the first transmission component, so that the blade holder moves to the cutting state and completes the blade release action. At the same time, the first transmission component and the second transmission component are in transmission cooperation and rotate synchronously. The walking frame is stationary relative to the guide rail. The cutting assembly achieves lifting and lowering in the opposite direction to S3 through the longitudinal transmission component.

[0030] S6, Return stroke: The first transmission component rotates relative to the second transmission component. While the walking frame moves along the guide rail, the cutting assembly achieves lifting and lowering in the opposite direction to S4 through the longitudinal transmission component, so that the tool holder completes the return stroke.

[0031] S7. Repeat S3-S6 above until the entire rubber tapping process is finished.

[0032] Through the above technical solution, the entire process relies entirely on the inherent logic of mechanical transmission to complete the action sequence control. During the installation stage, the second transmission component with the corresponding protrusion length is matched or the rotation gap is adjusted according to the selected cutter head (male or female). This allows the equipment to automatically obtain the required cutting direction and lifting characteristics for the cutter type during subsequent operation, ensuring that the cutting direction (up or down) is consistent with the working mode of the cutter, thus guaranteeing the quality of rubber tapping from the source. Secondly, the blade placement and retraction actions are performed when the walking frame is stationary. The first and second transmission components drive the longitudinal transmission component synchronously, which minimizes the problem of accidentally touching the bark or unstable placement and retraction during movement. During the cutting and return stages, the second transmission component locks and triggers the walking and lifting to proceed synchronously, ensuring that the spiral cutting line is continuous and uniform as much as possible.

[0052] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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.

[0053] It should be understood that in this invention, "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0054] The technical solution of the present invention will be described in detail below with reference to specific embodiments. The following specific embodiments may 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.

[0055] Example 1:

[0056] like Figures 1 to 17 As shown, the present invention provides a rubber tapping machine, including a walking assembly 1, a cutting assembly 2, and a coupling transmission unit 3. The walking assembly 1 includes a guide rail 11 and a walking frame 15 that slides with the guide rail 11. The walking assembly 1 is fixed to the surface of the rubber tree 4 through the guide rail 11. The guide rail 11 is arc-shaped and has deformation capability. The inner wall of the guide rail 11 is provided with protruding claws 111 to increase the positioning capability of the guide rail 11 on the rubber tree 4. The walking frame 15 is slidably installed on the outer periphery of the guide rail 11. When the walking frame 15 slides relative to the guide rail 11, the walking frame 15 slides around the outer surface of the rubber tree 4 to realize the circumferential sliding of the walking frame 15.

[0057] The walking frame 15 is equipped with a driver 10, and the coupling transmission unit 3 includes a first transmission component 31, a second transmission component 32, and a longitudinal transmission component 33. The first transmission component 31 is connected to the driver 10, and the longitudinal transmission component 33 is connected between the first transmission component 31 and the cutting assembly 2. The second transmission component 32 is mounted on the guide rail 11 and has a free-spinning state that is rotatable relative to the guide rail 11 and a locked state that forms a fixed engagement with the guide rail 11. In the free-spinning state, the first transmission component 31 and the second transmission component 32 are engaged in transmission and rotate synchronously, and the walking frame 15 is stationary relative to the guide rail 11. The cutting assembly 2 is raised and lowered through the longitudinal transmission component 33. In the locked state, the first transmission component 31 rotates relative to the second transmission component 32. While the walking frame 15 moves along the guide rail 11, the cutting assembly 2 is raised and lowered through the longitudinal transmission component 33. By utilizing the cooperative relationship between the first transmission component 31, the second transmission component 32 and the longitudinal transmission component 33, the orderly switching and coordinated operation of walking and cutting actions are realized under the drive of a single driver 10. This eliminates the need for multiple independent power sources and supporting control modules 14, greatly simplifying the overall structure and control system of the equipment. When the second transmission component 32 is in an idling state, it is not fixedly connected to the guide rail 11. The first transmission component 31 drives the second transmission component 32 to rotate synchronously. The power is transmitted to the cutting component 2 through the longitudinal transmission component 33, enabling it to complete the lifting and cutting action. Meanwhile, the walking frame 15 remains stationary due to the lack of relative driving force. When the second transmission component 32 switches to the locked state and forms a fixed engagement with the guide rail 11, the first transmission component 31 rotates relative to the second transmission component 32. At this time, part of the power is used to react on the guide rail 11 through the second transmission component 32, pushing the walking frame 15 to move along the guide rail 11. The other part still drives the cutting component 2 to lift and lower synchronously through the longitudinal transmission component 33. The switching between the two working states is achieved by the mechanical cooperation between the second transmission component 32 and the guide rail 11, without the need for complex electronic control algorithms, making the operation process simpler and more reliable.

[0058] It should be noted that there are two walking components 1, and the cutting component 2 is slidably assembled between the two walking components 1. One of the two walking components 1 is equipped with a driver 10, and the other is not equipped with a driver 10. Both walking components 1 are equipped with a guide rail 11, a first transmission component 31, and a second transmission component 32.

[0059] The guide rail 11 has a first position and a second position distributed along its extension direction. A second transmission member 32 is provided at each of the first and second positions. When the first transmission member 31 is at the first position, the cutting component 2 moves up and down in a first direction; when the first transmission member 31 is at the second position, the cutting component 2 moves up and down in a second direction, with the first and second directions being opposite. By utilizing a single driver 10 in conjunction with opposite lifting and lowering movements, reciprocating coverage of the rubber cutting path is achieved while maintaining a single motor drive.

[0060] Specifically, the second transmission member 32 is provided with a mating protrusion 321, and the guide rail 11 is provided with a guide groove 113 extending along the rotation direction of the second transmission member 32. The mating protrusion 321 extends into the guide groove 113. The second transmission member 32 is elastically loaded so that the mating protrusion 321 abuts against the first end 114 of the guide groove 113 in a free state. A rotation gap 116 is provided between the mating protrusion 321 and the second end 115 of the guide groove 113. When the first transmission member 31 drives the second transmission member 32 to rotate, the mating protrusion 321 idles within the rotation gap 116, and the second transmission member 32 and the guide rail 11 maintain relative rotation. The whole machine is in an idle state where the walking frame 15 is stationary and only the cutting component 2 is raised and lowered. As the rotation continues, the mating protrusion 321 finally abuts against the second end 115 of the guide groove 113. At this time, the second transmission member 32 is rigidly limited and forms a fixed fit with the guide rail 11, thereby converting the driving force into the reaction force required to push the walking frame 15 to move along the guide rail 11. The rotation clearance 116 provides the necessary motion tolerance for the transmission process, ensuring smooth rotation in the idling state and reliable locking through the rigid contact between the protrusion and the end face of the groove when reaching the set position, effectively transmitting the reaction force required for travel. The entire switching process relies solely on the motion relationship and elastic preload of the mechanical structure itself.

[0061] Specifically, the first transmission component 31 is a gear set, and the guide rail 11 is provided with teeth 112. The second transmission component 32 is an output gear 322 that is detachably mounted on the guide rail 11. The output gear 322 with different mating protrusion lengths 321 can be replaced according to the usage requirements of the male or female blade, thereby adjusting the idle angle and lifting sequence without modifying the main transmission structure. The gear set includes a first gear part 311 for meshing with the teeth 112 and a second gear part 312 for meshing with the output gear 322. The first gear part 311 and the second gear part 312 are coaxially arranged and fixedly connected by fasteners. Since the teeth 112 are used for conventional walking drive, they need to bear continuous load and ensure transmission smoothness. The corresponding first gear part 311 can adopt a high-precision, high-strength tooth profile. The output gear 322 only engages briefly at the end reversal or idle triggering. It has lower load requirements but higher requirements for action sensitivity. The corresponding second gear part 312 can be specifically designed with a light-load, easy-to-disengage tooth profile, such as a smaller tooth height and a slanted lead angle. By separating the two types of functions into different gear sections, the contradictory design of a single gear section that must meet both high-strength walking requirements and flexible disengagement is avoided. This improves the sensitivity of the tug response and the smoothness of disengagement without sacrificing reliability. When the walking frame 15 is in the position of the second transmission member 32, the second gear part 312 meshes with the output gear 322. When the second gear part 312 drives the output gear 322 to rotate, the cooperating protrusion 321 rotates freely in the rotation gap 116. The output gear 322 rotates relative to the guide rail 11, and the whole machine is stationary in the walking frame 15. At this time, the longitudinal transmission member 33 drives the cutting assembly 2 to rise and fall. As the rotation continues, the cooperating protrusion 321 finally abuts against the second end 115 of the guide groove 113. At this time, the second transmission member 32 is rigidly limited and forms a fixed engagement with the guide rail 11, thereby converting the driving force into the reaction force required to push the walking frame 15 to move along the guide rail 11. When the walking frame 15 leaves the position of the second transmission member, the first gear part 311 meshes with the teeth 112 of the guide rail 11 to push the whole machine to move along the guide rail 11.

[0062] The second transmission component 32 is elastically loaded by the first torsion spring 34 so that the mating protrusion 321 abuts against the first end 114 of the guide groove 113 in a free state. The second transmission component 32 is provided with an insertion hole 323, and the guide rail 11 is provided with a positioning hole 117. The two ends of the first torsion spring 34 are respectively inserted into the insertion hole 323 and the positioning hole 117. After the second transmission component 32 is assembled with the guide rail 11, the upper side of the second transmission component 32 is pressed by the cover plate 35. The cover plate 35 is connected to the guide rail 11 by screws to install the second transmission component 32.

[0063] Additionally, the system includes a control module 14 for controlling the drive unit 10, and a battery assembly 16 electrically connected to the drive unit 10. The walking frame 15 has a battery compartment 151 for mounting the battery assembly 16. The battery compartment 151 forms an opening 152 on the side of the walking frame 15 opposite to the guide rail 11, which minimizes interference between the battery compartment 151 and the sliding fit of the guide rail 11 and the rubber cutting work space, and also allows operators to directly access the battery area from the outside of the equipment, improving maintenance accessibility. The walking frame 15 also includes a cover 153 for closing the opening 152. The cover 153 is threaded to the opening 152. The threaded structure can be quickly tightened or loosened by hand, significantly simplifying the battery replacement and daily maintenance process. Meanwhile, a sealing ring 154 is provided between the inner wall of the cover 153 and the opening 152. Combined with the uniform clamping force provided by the threaded connection, the sealing ring 154 can stably fit the contact surface to form a reliable static seal. The thread itself also has a certain labyrinth barrier effect. The two work together to form a double sealing mechanism to prevent rainwater, latex, moisture and dust from entering the battery compartment 151 as much as possible, ensuring the long-term safe operation of the battery in the high humidity and pollution environment of the rubber forest. Magnets are provided at both ends of the teeth 112 of the guide rail 11. A sensor is provided in the walking frame 15. When the magnet approaches the sensor, the sensor will send an electrical signal. The control module 14 controls the driver 10 to shut down according to the electrical signal to prevent the walking frame 15 from separating from the guide rail 11 as much as possible.

[0064] The cutting assembly 2 includes a housing 20 and a blade holder 22 rotatably mounted on the housing 20. The blade holder 22 is equipped with a blade head 24. The housing 20 is connected to the first transmission member 31 via a longitudinal transmission member 33. The housing 20 can be raised and lowered relative to the traveling frame 15. During the sliding of the traveling frame 15 along the guide rail 11, the housing 20 slides synchronously along the circumferential direction with the traveling frame 15. The blade holder 22 has a cutting state away from the housing 20 and a retracted state close to the housing 20. In the cutting state, the blade head 24 abuts against the surface of the tree. Through the sliding of the housing 20, the blade head 24 can cut a cutting line on the tree to achieve the cutting effect of the rubber tapping machine. In the retracted state, the blade head 24 does not come into contact with the tree, and the rubber tapping machine will not cut the tree. It should be noted that the rubber tapping machine is mainly used for cutting rubber trees 4. Of course, the rubber tapping machine can also be used for other types of trees. The following description uses rubber tree 4 to refer to the tree body.

[0065] To accommodate multiple cutting methods, the cutter head 24 and the cutter holder 22 are detachably connected. The cutter head 24 includes both male and female cutters, allowing users to select the appropriate cutter head 24 to install on the cutter holder 22 as needed. This achieves compatibility between two cutting methods within the same equipment set without altering the main layout of the traveling assembly 1, reducing the user's reliance on multiple cutting devices. Correspondingly, when the first transmission component 31 is in the first position, the cutting assembly 2 has a first lifting stroke; when the first transmission component 31 is in the second position, the cutting assembly 2 has a second lifting stroke. The first and second lifting strokes are not equal. This stroke difference results in a directional net cutting displacement during the reciprocating motion: if the first lifting stroke is greater than the second lifting stroke, the net cutting direction is upward, suitable for the female cutter's working method; if the first lifting stroke is less than the second lifting stroke, the net cutting direction is downward, suitable for the male cutter's working method. Therefore, after changing the type of cutter head 24, the equipment requires no additional adjustment and can automatically match the corresponding cutting direction based on the preset stroke asymmetry, ensuring that the cutter action is consistent with the cutting process requirements, balancing ease of operation and operational reliability.

[0066] Since the extension lengths of the rotation gaps 116 corresponding to the two second transmission components 32 are the same, and the mating protrusion 321 extends into the guide groove 113, its own length directly determines the range of angles that can be freely rotated within the idle range of the guide groove 113: the longer the mating protrusion 321, the smaller the idle angle that can be rotated within the same length of the rotation gap 116; conversely, the shorter the mating protrusion 321, the larger the idle angle. The lifting stroke of the cutting assembly 2 is determined by the angle rotated by the first transmission component 31 driving the second transmission component 32 during the idle phase. Therefore, in this application, the mating protrusions 321 of the two second transmission components 32 have different lengths along the rotation direction of the second transmission component 32. The mechanical design of adjusting the length of the mating protrusion 321 to control the idle stroke does not require changing the structure of the guide groove 113. After the cutter head 24 is replaced, its stroke characteristics can be adapted by changing the mating protrusion 321. When the upward movement at the first position is greater than the downward movement at the second position, the net cutting direction is upward, which is suitable for the bottom-up cutting mode required by the negative knife; conversely, when the downward movement is greater than the upward movement, the net cutting direction is downward, which is suitable for the top-down cutting mode required by the positive knife.

[0067] To facilitate the replacement of the blade head 24, the cutting assembly 2 also includes a blade head bracket 260, a pressure plate 261, screws, and a spring 262. The blade head 24 is placed on the blade head bracket 260 and is detachably mounted to the blade head bracket 260 via the pressure plate 261 and screws. The blade head bracket 260 is detachably connected to the blade holder 22 via screws and is elastically connected to the blade holder 22 via the spring 262. The spring 262 provides appropriate floating cushioning during rubber tapping, allowing the blade head 24 to conform to the unevenness of the bark surface, reducing rigid impact, helping to protect the blade and improve the quality of rubber tapping. The blade head bracket 260 can be either a male or female blade head bracket, allowing both types of blade head brackets 260 to be adapted to the same blade holder 22. Switching between tapping modes only requires replacing the corresponding type of blade head bracket 260 and blade head 24, without modifying the blade holder 22 itself or other components, making blade head 24 switching simpler.

[0068] To achieve the state switching of the tool holder 22, the coupling transmission unit 3 also includes a third transmission component 36 and a fourth transmission component 37. The third transmission component 36 is connected to the first transmission component 31, and the fourth transmission component 37 is connected to the tool holder 22 via the transmission shaft 13. When the second transmission component 32 is in an idling state, the third transmission component 36 and the fourth transmission component 37 engage in a transmission to drive the fourth transmission component 37, causing the tool holder 22 to switch between the cutting state and the retracting state. When the second transmission component 32 is in a locked state, the third transmission component 36 and the fourth transmission component 37 disengage, and the tool holder 22 maintains its current state. The state switching is completely completed automatically by the coupling and disengagement of the mechanical transmission, which is simpler and more reliable.

[0069] The fourth transmission member 37 includes a sector gear 371, a first one-way transmission member 372, and a second one-way transmission member 373 arranged coaxially. The sector gear 371 is inserted into the transmission shaft 13 and rotates synchronously. The first transmission member 31 is provided with a third gear part 313. The third transmission member 36 meshes between the third gear part 313 and the sector gear 371. The first transmission member 31 transmits torque to the sector gear 371 through the third transmission member 36. The fourth transmission member 37 has a first state in which the sector gear 371 disengages from the third transmission member 36 by rotating in a first direction, and a second state in which the sector gear 371 disengages from the third transmission member 36 by rotating in a second direction. When the fourth transmission member 37 reaches the first state, it drives the tool holder 22 to move to the cutting state through the transmission shaft 13. When the fourth transmission member 37 reaches the second state, it drives the tool holder 22 to move to the retracted state through the transmission shaft 13. In the first state, the third transmission member 36 drives the fourth transmission member 37 to rotate towards the second state via the first one-way transmission member 372. In the second state, the third transmission member 36 drives the fourth transmission member 37 to rotate towards the first state via the second one-way transmission member 373. The sector gear 371 can quickly adjust its rotation angle with the third transmission member 36 to limit the rotation amplitude of the tool holder 22. At the same time, the sector gear 371 can quickly disengage from the third transmission member 36, making the state switching of the tool holder 22 faster and more precise. In addition, after the sector gear 371 disengages from the third transmission member 36, it can be rotated in the opposite direction via the first one-way transmission member 372 or the second one-way transmission member 373, so that the sector gear 371 can re-engage with the third transmission member 36, ensuring that the sector gear 371 can reciprocate within a certain angle range, so that the tool holder 22 can switch between the retracted state and the cutting state.

[0070] It should be noted that the output end of the driver 10 is connected to the third gear section 313, and the third gear section 313 is connected to the second gear section 312 via the fourth gear section 314. By changing the size of the fourth gear section 314, the transmission ratio can be changed, and the lifting amount or stroke response characteristics of the cutting assembly 2 can be adjusted.

[0071] The sector gear 371 has a rotating shaft 374 extending axially and to both the upper and lower sides in the middle. The first one-way transmission member 372 and the second one-way transmission member 373 are rotatably mounted on the rotating shaft 374 on the upper and lower sides of the sector gear 371, respectively. The outer wall of the rotating shaft 374 is provided with a protruding positioning block 375. Both the first one-way transmission member 372 and the second one-way transmission member 373 are provided with a groove 3722 for the positioning block 375 to slide. Both the first one-way transmission member 372 and the second one-way transmission member 373 are elastically loaded so that the positioning block 375 abuts against one end of the groove 3722, and there is a rotational gap between the positioning block 375 and the other end of the groove 3722.

[0072] The positioning blocks 375 on the upper and lower sides of the sector gear 371 are respectively inserted into the grooves 3722 of the first one-way transmission member 372 and the second one-way transmission member 373. The grooves 3722 are larger than the positioning blocks 375, allowing the positioning blocks 375 to slide relative to the grooves 3722. This means the first one-way transmission member 372 and the second one-way transmission member 373 can rotate relative to the rotating shaft 374. The first one-way transmission member 372 has a tendency to rotate in the second direction. The first one-way transmission member 372 and the sector gear 371 are in the first direction... The two parts can slide relative to each other and rotate synchronously in the second direction; the second one-way transmission member 373 has a tendency to rotate in the first direction. The second one-way transmission member 373 and the sector gear 371 can slide relative to each other in the second direction and rotate synchronously in the first direction. After the sector gear 371 disengages from the third transmission member 36 in one of the directions, the first one-way transmission member 372 or the second one-way transmission member 373 cooperates with the transmission component so that the sector gear 371 can only rotate in the opposite direction so that the sector gear 371 can re-engage with the third transmission member 36.

[0073] The outer periphery of the first one-way transmission member 372 and the second one-way transmission member 373 are respectively provided with a first protrusion 3721 and a second protrusion 3731, which are respectively located at both ends of the teeth of the sector gear 371; the third transmission member 36 includes a transmission gear 361, a first transmission block 362 and a second transmission block 363, wherein the transmission gear 361 meshes with both the sector gear 371 and the third gear part 313, and the first transmission block 362 and the second transmission block 363 are respectively located on the upper and lower sides of the transmission gear 361, and the teeth of the transmission gear 361... The first transmission block 3721 and the first transmission block 362 are on the same horizontal plane as the first transmission block 371, and the second transmission block 3731 and the second transmission block 363 are on the same horizontal plane. In the first state, the first transmission block 362 pushes the fourth transmission member 37 to rotate in the second direction through the first transmission block 3721 so that the transmission gear 361 meshes with the sector gear 371. In the second state, the second transmission block 363 pushes the fourth transmission member 37 to rotate in the first direction through the second transmission block 3731 so that the transmission gear 361 meshes with the sector gear 371.

[0074] Specifically, the first one-way transmission member 372 tends to rotate counterclockwise under the action of the second torsion spring 376. The positioning block 375 abuts against one end of the groove 3722 to restrict the counterclockwise rotation of the first one-way transmission member 372. There is a rotational gap between the positioning block 375 and the other end of the groove 3722, so the first one-way transmission member 372 can rotate clockwise relative to the sector gear 371. When the first transmission member 31 of the driver 10 rotates forward, the transmission gear 361 drives the sector gear 371 to rotate forward. When the sector gear 371 rotates and disengages from the transmission gear 361, the first protrusion 3721 approaches the transmission gear 361. During the rotation of the transmission gear 361, the first transmission block 362 will contact the first protrusion 3721. When the driver 10 continues to output forward, the first transmission block 362 will drive the first protrusion 3721 to rotate clockwise. Since the positioning block 375 and the groove 372... There is a rotational gap between the two components. The first one-way transmission component 372 can rotate clockwise, thereby disengaging the first protrusion 3721 from the first transmission block 362. Under the elastic action, the first one-way transmission component 372 will automatically rotate back, so the driver 10 continues to output in the forward direction. The first one-way transmission component 372 will oscillate back and forth under the action of the first protrusion 3721, while the sector gear 371 remains stationary. When the driver 10 rotates in the reverse direction, the first transmission block 362 will drive the first protrusion 3721 to rotate counterclockwise. Since the positioning block 375 abuts against the groove 3722 to restrict the counterclockwise rotation of the first one-way transmission component 372 relative to the sector gear 371, the first one-way transmission component 372 will drive the sector gear 371 to rotate counterclockwise synchronously, so that the sector gear 371 can mesh with the transmission gear 361 again. In addition, the second one-way transmission component 373 works on the same principle as the first one-way transmission component 372.

[0075] It should be noted that the clockwise direction of the first one-way transmission member 372 is the first direction mentioned above, and the counterclockwise direction of the first one-way transmission member 372 is the second direction mentioned above.

[0076] It should be noted that the cutting assembly 2 also includes a sliding seat 21, which is slidably disposed within the housing 20. One end of the blade holder 22 is provided with a blade head 24, and the other end is connected to the sliding seat 21. The middle part of the blade holder 22 is rotatably connected to the housing 20. The sliding seat 21 slides relative to the housing 20, thereby causing the blade holder 22 to swing. The sliding seat 21 includes a base 211, a top cover 212, and a cam 213 rotatably disposed between the two. The drive shaft 13 passes through the cam 213 and rotates synchronously with the cam 213. The drive shaft 13 drives the cam 213 to rotate. The outer protrusion of the cam 213 acts on the base 211, thereby causing the base 211 to slide within the housing 20. The end of the housing 20 is connected to the blade holder 22 through a tension spring 25, so that the blade holder 22 has elasticity, so that the blade holder 22 can be used for rubber trees 4 of different diameters. The housing 20 is rotatably provided with a rotating output component 27, which is threadedly connected to a longitudinal transmission component 33, which can be a lead screw.

[0077] It should be noted that the components of the guide rail 11 include mounting the first torsion spring 34 onto the output gear 322, wherein one end of the first torsion spring 34 is installed into the insertion hole 323 of the output gear 322 to form a whole; then the whole is installed into the first position of the guide rail 11, and is installed into the guide groove 113 in conjunction with the protrusion 321, and the other end of the first torsion spring 34 is installed into the positioning groove of the guide rail 11; finally, the top cover 212 plate is installed and the screws are tightened. The installation of the second position is the same as that of the first position, so it will not be described in detail.

[0078] Working principle:

[0079] A rubber tapping machine needs to complete several actions to work. The sequence is: placing the blade, running the cutting machine, retracting the blade, and running the reverse machine. These four actions must be performed in the correct order; otherwise, the cutting cannot be completed smoothly.

[0080] First, put down the knife:

[0081] When the driver 10 starts rotating forward, it drives the first transmission component 31. The first transmission component 31 engages with the second transmission component 32 at the first position. The second transmission component 32 is in an idle state. At this time, the cutting assembly 2 rises vertically under the drive of the longitudinal transmission component 33. At the same time, the third transmission component 36 and the fourth transmission component 37 cooperate, and the transmission shaft 13 drives the cam 213 to rotate clockwise. The rotation of the cam 213 drives the sliding seat 21 to move. Under the action of the tension spring 25, the tool holder 22 rotates to release the blade.

[0082] Second, run the cutting process:

[0083] As the second transmission component 32 continues to move along the guide groove 113 with the engagement protrusion 321, when the rotation gap 116 is exhausted, the engagement protrusion 321 contacts the second end 115 of the guide groove 113, and the second transmission component 32 is locked and can no longer rotate. The rubber tapper will then move forward horizontally under the drive of the first transmission component 31. When the machine is out of the engagement range of the second transmission component 32, the second transmission component 32 will return to its initial position under the torsion of the torsion spring, that is, the engagement protrusion 321 contacts the first end 114 of the guide groove 113. At the same time, the longitudinal transmission component 33 drives the cutting component 2 to rise vertically, so that the machine runs in both horizontal and vertical directions at the same time, cutting a spiral line on the tree surface.

[0084] Third, sheathe the sword:

[0085] After the machine completes one cut, the sensor approaches the magnet on the guide rail 11 and sends an electrical signal. The control module 14 controls the driver 10 to shut down according to the electrical signal to complete the cutting action of the blade holder 22. The first transmission component 31 is in the second position. Then the driver 10 starts to reverse and drive the first transmission component 31 to rotate counterclockwise. The first transmission component 31 engages with the second transmission component 32 in the second position. The second transmission component 32 is in an idle state. At this time, the cutting assembly 2 descends vertically under the drive of the longitudinal transmission component 33. At the same time, the third transmission component 36 and the fourth transmission component 37 cooperate, and the transmission shaft 13 drives the cam 213 to rotate counterclockwise. The rotation of the cam 213 drives the sliding seat 21 to move. Under the action of the tension spring 25, the blade holder 22 rotates to retract the blade.

[0086] Fourth, run in reverse:

[0087] As the second transmission component 32 continues to move along the guide groove 113 with the engaging protrusion 321, when the rotation gap 116 is exhausted, the engaging protrusion 321 contacts the second end 115 of the guide groove 113, and the second transmission component 32 is locked and can no longer rotate. The rubber tapper will then move backward horizontally under the drive of the first transmission component 31. When the machine disengages from the engagement range of the second transmission component 32, the second transmission component 32 will return to its initial position under the torque of the torsion spring, that is, the engaging protrusion 321 contacts the first end 114 of the guide groove 113. At the same time, the longitudinal transmission component 33 drives the cutting assembly 2 to descend vertically. As the movement continues, when the sensor approaches the magnet of the guide rail 11, the machine returns to the initial cutting position. The sensor sends an electrical signal, and the control module 14 controls the driver 10 to shut down according to the electrical signal, thus completing the entire movement process of the rubber tapper.

[0088] Understandably, in other embodiments, since the lifting stroke of the cutting assembly depends on the angle rotated by the first transmission member in the idle state of the second transmission member, during this stage, power continuously drives the cutting assembly to lift and lower via the longitudinal transmission member. Once the engagement protrusion abuts against the limiting end of the guide groove, the second transmission member enters the locked state, and the walking action of the frame relative to the guide rail begins, thus initiating cutting. Therefore, the longer the rotation gap, the larger the allowable idle angle, and the longer the lifting stroke of the cutting assembly. The working methods of the male and female blades are fundamentally different. The male blade typically completes effective rubber cutting during the descent, while the female blade mainly achieves cutting during the ascent. To address this difference, by varying the length of the rotation gaps corresponding to the two second transmission members along the rotation direction of the second transmission member, the equipment can provide the lifting stroke required for either the male or female blade when traveling back and forth to the first or second position. For example, when a male blade is installed, the downward position corresponds to a longer rotation gap, ensuring sufficient cutting depth; when replaced with a female blade, the return position is configured with a longer rotation gap to ensure sufficient effective cutting stroke during the ascent.

[0089] In addition, the extension length of the guide groove and the size of the mating protrusion along the rotation direction can be adjusted synchronously according to the different required lifting strokes, so as to coordinately control the rotation angle range during the idling stage, thereby flexibly adapting to different cutting process requirements.

[0090] Example 2:

[0091] In this embodiment, a rubber tapping method is provided. The rubber tapping machine adopts any of the above-mentioned technical solutions, and the rubber tapping method of the rubber tapping machine is as follows:

[0092] S1. Installation: Select the male or female blade according to the rubber tapping requirements, and install the selected blade head onto the blade holder. At the same time, adjust the length of the rotation clearance along the rotation direction of the second transmission component, or select a second transmission component with a matching protrusion of different lengths to match the selected blade head.

[0093] S2, Fixing: The walking component is fixed to the tree body via guide rails;

[0094] S3, Tool Release: The driver drives the longitudinal transmission component through the first transmission component to move the tool holder to the cutting state and complete the tool release action. At the same time, the first transmission component and the second transmission component are driven and rotate synchronously. The traveling frame is stationary relative to the guide rail, and the cutting assembly is raised and lowered through the longitudinal transmission component.

[0095] S4. Cutting: The first transmission component rotates relative to the second transmission component. While the walking frame moves along the guide rail, the cutting component is raised and lowered through the longitudinal transmission component, so that the blade holder cuts a spiral line on the tree.

[0096] S5, Retracting the blade: After cutting is completed, the driver drives the longitudinal transmission component in the opposite direction through the first transmission component, so that the blade holder moves to the cutting state and completes the blade release action. At the same time, the first transmission component and the second transmission component are driven and rotate synchronously. The walking frame is stationary relative to the guide rail, and the cutting component is raised and lowered in the opposite direction to S3 through the longitudinal transmission component.

[0097] S6, Return stroke: The first transmission component rotates relative to the second transmission component. While the traveling frame moves along the guide rail, the cutting assembly achieves lifting and lowering in the opposite direction to S4 through the longitudinal transmission component, so that the tool holder completes the return stroke.

[0098] S7. Repeat S3-S6 above until the entire rubber tapping process is finished.

[0099] The entire process relies entirely on the inherent logic of mechanical transmission to control the timing of actions. During the installation phase, a second transmission component with a corresponding protrusion length is matched or the rotation gap is adjusted according to the selected cutter head (male or female). This allows the equipment to automatically acquire the required cutting direction and lifting characteristics for the cutter type during subsequent operation, ensuring that the cutting direction (up or down) is consistent with the working mode of the cutter, thus guaranteeing the quality of rubber tapping from the source. Secondly, the blade placement and retraction actions are performed when the walking frame is stationary. The first and second transmission components drive the longitudinal transmission component synchronously, minimizing the risk of accidentally touching the bark or unstable placement and retraction during movement. During the cutting and return phases, the second transmission component locks and triggers the walking and lifting to proceed synchronously, ensuring that the spiral cutting line is continuous and uniform as much as possible.

[0100] In addition to the preferred embodiments described above, the present invention has other embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection claimed by the present invention.
