Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rubber tree automatic tapping equipment and auxiliary components, in particular to a rail device for a tapping machine. BACKGROUND

[0002] Natural rubber, as an important industrial raw material, is obtained by tapping rubber trees, which involves making a specific angle and depth incision on the phloem of the rubber tree trunk to guide the rubber juice (latex) in the tree to flow out and be collected. Currently, India, Malaysia, China and other major global rubber-producing regions are the core supply sources of natural rubber, and the efficiency and quality of tapping operations directly determine the economic benefits of the rubber industry.

[0003] With the large-scale development of the rubber industry, the traditional manual tapping method has gradually exposed problems such as low efficiency, high labor intensity, and dependence on skilled workers (difficulty in uniformity of incision precision), so automatic tapping machines have become an important direction for the upgrading of the industry. The operation logic of existing automatic tapping machines is to install a ring-shaped rail on the rubber tree trunk, allowing the tapping machine head to move stably around the trunk along the rail, thereby achieving automatic incision operation. The rail, as the running reference for the tapping machine, directly determines the running stability and incision precision of the tapping machine.

[0004] However, the current automatic tapping machine uses a one-piece circular single rail. This type of rail design is based on the ideal assumption that the rubber tree trunk is a standard cylinder, with a regular circular inner circle that needs to be completely wrapped around the trunk and fixed by buckles or straps during installation. However, in actual production, the rubber tree is affected by natural factors such as growth environment (such as light and wind), tree age, and bark growth characteristics (such as knots, protrusions, longitudinal line depressions, and local pits), so the trunk surface is not a regular cylindrical body. On the one hand, the cross-section of the trunk is mostly elliptical or irregular polygonal, with a diameter deviation of ±5%-15%; on the other hand, the bark surface often has protruding knots, longitudinal cracks forming pits, or local height differences due to previous tapping residues, resulting in poor surface flatness.

[0005] The above-mentioned irregular characteristics of the trunk directly lead to the following problems in the installation of traditional circular rails: 1. Large installation deviation: The circular rail cannot adapt to the protrusions and pits of the trunk, resulting in a large gap (up to 5-10 mm) between the inner circle of the rail and the surface of the trunk after installation, or local extrusion due to the protrusions of the trunk, causing the center of the rail to deviate from the center of the trunk, forming an "eccentric rail"; 2. High installation difficulty: To reduce the gap, the operator needs to use additional gaskets to raise, polish the bark protrusions and other auxiliary measures, which not only increases the installation time (single tree track installation time increases by 30%-50% compared with the ideal state), but also may damage the bark phloem due to excessive polishing, affecting the subsequent rubber yield; 3. The quality of rubber tapping and the stability of the equipment are affected: the track with large local gap or deviation will cause the tapping head to shake and jam when moving along the track, resulting in uneven incision depth (deviation up to 0.5-1mm), incision direction deviation, and even the tapping head colliding with the tree trunk protrusions and stopping. At the same time, the non-adhesion contact between the track and the tree trunk during long-term operation will accelerate the wear of the track, causing the track to loosen and further reducing the reliability of the rubber tapping operation.

[0006] 4. When facing large protrusions on the tree trunk, the existing adjustable support type track has obvious limitations: first, if the support point is rigidly designed, the protrusions will cause strong interference, and forced installation may cause deformation of the track or damage to the bark. Lack of space, the protrusions directly press on the track body, affecting its normal function and even causing jamming. When the protrusions are located at the fixed tooth structure that provides the main gripping force, it will cause the gripping force at this position to abnormally increase or completely fail, disrupting the uniform distribution of the gripping force.

[0007] In summary, the existing automatic rubber tapping machine has a single circular track that cannot adapt to the natural irregular characteristics (protrusions, pits, irregular cross-section) of the rubber tree trunk, resulting in large installation deviation, high installation difficulty, and affecting the quality of rubber tapping. The key technical bottleneck that restricts the large-scale application of automatic rubber tapping machines is the need for a track structure that can adapt to the irregular surface of the rubber tree to solve the above technical problems.

DETAILED DESCRIPTION

[0034] The application will be further described below in detail with reference to the accompanying drawings.

[0035] The technical solutions in the application will be described clearly and completely below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the application, rather than all the embodiments. The components of the application described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of the application. Based on the embodiments of the application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of the application.

[0036] The application discloses a track device for a rubber tapping machine. Figure 1 and Figure 2 The track device comprises a gear ring 100, a fitting claw 20, a gripping tooth 120 and an adjusting assembly. The gear ring 100 is used as the main structure of the whole track device and is designed as a C-shaped opening. The material of the gear ring 100 is preferably plastic. The outer ring of the gear ring 100 is provided with meshing teeth 110 in the circumferential direction, which are used to mesh with the driving mechanism (such as a gear or a chain) of the rubber tapping machine, so as to provide a running track for the rubber tapping machine to move around the rubber tree. The inner ring of the gear ring 100 is provided with gripping teeth 120 for gripping the rubber tree in the circumferential direction, and a plurality of fitting claws 20 are uniformly distributed in the circumferential direction. The C-shaped opening design of the gear ring 100 enables the gear ring 100 to be conveniently sleeved on the trunk of the rubber tree, and the preliminary fixation can be completed without completely surrounding the trunk. During installation, the operator can clamp the gear ring 100 at the specified height position of the trunk through the opening, then adjust the extension distance of the fitting claw 20 through the adjusting assembly, so that the fitting claw 20 closely fits the surface of the trunk, and finally the two ends of the opening can be connected and fixed through additional fastening belts or buckles, so as to ensure the stability of the whole gear ring 100.

[0037] Referring to Figure 5 and Figure 6 , specifically, a plurality of fitting claws 20 are provided, and the plurality of fitting claws 20 are uniformly distributed along the inner circle of the gear ring 100. Each fitting claw 20 comprises a claw body 21 and a contact protrusion 22. The claw body 21 is designed as a rectangular plate structure, and the material is preferably wear-resistant engineering plastic. Four contact protrusions 22 are integrally formed on the side of the claw body 21 away from the central axis of the gear ring 100, respectively at the four corners of the claw body 21.

[0038] Referring to Figure 5 and Figure 6 , the contact protrusion 22 is integrally formed by two right-angled triangular plates 222. The right-angled edges of the two triangular plates 222 are fixedly connected, and the oblique edges respectively extend along the length direction of the adjacent two edges of the claw body 21. The two oblique edges converge at one end to form a sharp spike 221. This design allows the spike 221 to embed into the tiny gap on the surface of the tree bark when the fitting claw 20 is fitted to the tree trunk, thereby enhancing the connection stability of the fitting claw 20 and the tree trunk, and preventing the track from slipping during the operation of the rubber tapping machine.

[0039] Referring to Figure 5 and Figure 6 , each fitting claw 20 is provided with a set of adjusting assembly for adjusting the radial extension distance of the fitting claw 20 along the gear ring 100, so as to adapt to rubber tree trunks of different diameters and surface shapes. The adjusting assembly comprises a ball 31, an adjusting part 32, a mounting column 33 and an adjusting knob 34.

[0040] Referring to Figure 4 , Figure 5 and Figure 6 , a circular clamping groove 23 is formed in the middle position of the claw body 21, and an arc-shaped groove 223 is formed in the inner wall of the clamping groove 23, facing away from the center of the claw body 21. Thanks to the arc surface provided by the arc-shaped groove 223, the ball 31 is rotatably installed in the clamping groove 23, and the outer surface of the ball 31 is tightly fitted with the inner surface of the arc-shaped groove 223, so that the ball 31 can freely rotate around its ball center in the clamping groove 23. This ball hinge connection structure allows the fitting claw 20 to freely swing within a certain angle range, so as to adapt to the inclination or irregular shape of the rubber tree trunk surface, and ensure the effective contact of the contact protrusion 22 with the trunk surface.

[0041] Referring to Figure 4 and Figure 5 , the adjusting part 32 is integrally formed at the end of the ball 31 away from the fitting claw 20, and the outer peripheral surface of the adjusting part 32 is provided with external threads. The mounting column 33 is fixedly arranged in the inner circle of the gear ring 100, comprising a first mounting body 331 and a second mounting body 333 which are symmetrically arranged along the ring direction of the gear ring 100, forming an adjusting groove 334 for accommodating the adjusting part 32.

[0042] With reference to Figure 5 , the first mounting body 331 and the second mounting body 333 are provided with a limiting stop 332 on the outer surface away from the adjusting groove 334, for axially limiting the adjusting knob 34. The adjusting part 32 passes through the adjusting groove 334, and the outer thread thereof is matched with the inner thread of the adjusting knob 34. By rotating the adjusting knob 34, the adjusting part 32 can be driven to move radially along the gear ring 100, so as to adjust the extension distance of the clamping jaw 20.

[0043] With reference to Figure 5 , the adjusting knob 34 is designed as a circular disc structure, and the outer circumferential surface thereof is processed with anti-skid lines 342, facilitating the rotation of the adjusting knob 34 by the operator with hands or tools. A through constraint hole 341 is arranged at the center position of the adjusting knob 34, and the constraint hole 341 is adapted to the combined section of the first mounting body 331 and the second mounting body 333, and is sleeved on the outer side of the two.

[0044] With reference to Figure 5 , the two sides of the adjusting knob 34 are respectively abutted with the inner ring end face of the gear ring 100 and the end face of the limiting stop 332, forming axial limiting, so as to ensure that the adjusting knob 34 can only rotate around the mounting column 33 and cannot axially move. The inner wall of the constraint hole 341 is processed with an inner thread, which is adapted to engage with the outer thread of the adjusting part 32. When the adjusting knob 34 is rotated, the engagement of the inner thread and the outer thread will drive the adjusting part 32 to move radially along the gear ring 100, thereby driving the ball 31 and the clamping jaw 20 to move synchronously, so as to realize the accurate adjustment of the extension distance of the clamping jaw 20.

[0045] With reference to Figure 2 and Figure 4 , the inner ring of the gear ring 100 is fixedly provided with an elastic rib 130, and the elastic rib 130 is continuously arranged along the length direction of the inner ring of the gear ring 100. The clamping teeth 120 are integrally formed on the surface of the elastic rib 130 away from the gear ring 100, and are uniformly distributed along the length direction of the elastic rib 130. A reinforcing rib 140 is arranged along the length direction of the elastic rib 130, and the reinforcing rib 140 is perpendicular to the elastic rib 130. The reinforcing rib 140 is provided with a plurality of reinforcing ribs 140 along the length direction of the elastic rib 130, and the structure stability and stress balance of the elastic rib 130 are strengthened without damaging the deformation ability of the elastic rib 130 itself.

[0046] With reference to Figure 2 and Figure 3The holding tooth 120 comprises an elastic part 1201 and a thorn part. The elastic part 1201 is designed as a U-shaped structure and is made of plastic and has a certain elastic deformation capacity. The open end of the U-shaped elastic part 1201 faces the elastic rib 130 and is fixedly connected with the elastic rib 130, and the closed end is provided with a thorn part. The thorn part includes a first thorn part 1202 and a second thorn part 1203, which are diagonally distributed with the center of the closed end of the elastic part 1201 as the reference. The length of the first thorn part 1202 is longer than that of the second thorn part 1203, and the extension directions of the planes of the maximum cross sections of the two thorn parts form an angle of 90°.

[0047] With reference to Figure 2 and Figure 3 The two adjacent holding teeth 120 are centrally symmetrically arranged with the circumferential tangent direction of the tooth ring 100 as the axis of symmetry. This arrangement enables the holding tooth 120 to penetrate into the surface layer of the bark from multiple directions, thereby enhancing the connection strength between the track and the tree trunk. The elastic deformation capacity of the elastic part 1201 and the elastic rib 130 enables the holding tooth 120 to elastically deform when subjected to external pressure, thereby adapting to the irregular shape of the surface of the tree trunk and avoiding track deformation or bark damage caused by local extrusion.

[0048] With reference to Figures 7-9 To realize the adaptive accommodation of the fitting claw 20 to the protruding part of the rubber tree trunk, a housing 40, a contraction assembly and a sliding assembly are further added in the adjusting assembly.

[0049] The housing 40 is embedded in the position corresponding to the fitting claw 20 in the inner circle of the tooth ring 100, and has a cylindrical shape with an opening facing the inner circle of the tooth ring 100. The side wall of the housing 40 is provided with a contraction opening 41 for the claw body 21 to enter and exit. The housing 40 is internally provided with a sliding groove 42, and a sliding rod 43 is fixed to the adjusting part 32 and inserted into the sliding groove 42, so that the adjusting part 32 can only move radially along the tooth ring 100 and cannot rotate circumferentially, thereby ensuring the stability of the adjustment.

[0050] The contraction assembly comprises a sleeve rod 44, a connecting rod 45 and a contraction spring 46. The sleeve rod 44 is fixed to the inner side of the adjusting knob 34, the connecting rod 45 is fixed to the inside of the housing 40, and the two are coaxially arranged, with the sleeve rod 44 being sleeved outside the connecting rod 45. The inner wall of the sleeve rod 44 and the outer wall of the connecting rod 45 are provided with corresponding threads, forming a lockable threaded connection. The contraction spring 46 is sleeved outside the two, one end abuts against the inner wall of the housing 40, and the other end abuts against the adjusting knob 34, thereby providing the adjusting knob 34 with an elastic pushing force towards the outside of the housing 40.

[0051] When the adjusting knob 34 is rotated to make the fitting claw 20 outwardly extend to fit the groove of the tree trunk, the sleeve rod 44 rotates with the adjusting knob 34, and the internal threads thereof gradually engage and lock with the external threads of the connecting rod 45, forming a rigid connection to keep the fitting claw 20 in a stable extended state.

[0052] When the adjusting knob 34 is rotated in the opposite direction or the protrusion on the trunk presses against the fitting claw 20, the threaded connection gradually disengages, and the sleeve 44 regains its axial movement capability relative to the connecting rod 45. Under the pushing force of the protrusion or manual pressing, the fitting claw 20 can retract into the housing 40 along the slide groove 42, and the contraction spring 46 is compressed, achieving adaptive clearance to the protruding part. After the protrusion passes this position, the contraction spring 46 pushes the fitting claw 20 back to its original position, continuing to maintain contact with the trunk.

[0053] Furthermore, the clamping teeth 120 are detachably mounted to the elastic ribs 130 via slots 1024 at their bottom. In areas with numerous protrusions on the trunk surface, the detachable clamping teeth 120 allow space to accommodate the protrusions, preventing localized compression. The clamping teeth 120 can also be replaced with different sizes according to the trunk diameter, improving the adaptability of the device.

[0054] A detection component, including multiple fixed vertical plates 47, force sensors 48, and tension springs 49, can be installed on the elastic rib 130 to monitor the opening degree of the toothed ring 100 in real time. If the opening degree of the toothed ring 100 is large, the tree trunk is thicker. The tension spring 49 exerts a greater force on the force sensors 48 on both sides, and the data detected by the force sensors 48 increases. Conversely, if the opening degree of the toothed ring is small, the detection value of the force sensors 48 is smaller, and the tree trunk tends to be thinner. Depending on whether the tree trunk is thick or thin, the retraction or extension of the fitting claw 20 is adjusted accordingly to adjust the clamping force of the toothed ring 100 on the tree trunk.

[0055] The implementation principle of this application embodiment is as follows: The working principle of the rubber tapping machine track device of the present invention is based on an adaptive fitting design. Through adjustable fitting claws 20 and elastic clamping teeth 120, it achieves effective adaptation to the irregular surface of the rubber tree trunk. The specific installation and debugging process is as follows: 1. Initial installation: The operator will attach the toothed ring 100 to the designated height position on the trunk of the rubber tree through the C-shaped opening, so that the toothed ring 100 roughly encircles the trunk.

[0056] 2. Adjusting the position of the bonding claws 20: The operator rotates the adjustment knob 34 corresponding to each bonding claw 20 one by one. Through the threaded engagement of the adjustment knob 34 and the adjustment part 32, the bonding claw 20 is driven to move radially towards the trunk along the toothed ring 100 until the contact protrusion 22 contacts the surface of the trunk. During this process, due to the ball-joint connection structure between the ball 31 and the locking groove 23, the bonding claw 20 will automatically adjust its posture according to the tilt angle of the trunk surface, so that the barbs 221 of the contact protrusion 22 can effectively embed into the tiny gaps on the bark surface.

[0057] 3. Tightening and verification: After completing the initial adjustment of all the bonding claws 20, the operator uses fastening straps or buckles to connect and fix the two ends of the opening of the toothed ring 100. Then, check the bonding of each bonding claw 20 again, and make fine adjustments to the parts that are not tightly bonded to ensure that all bonding claws 20 are in close contact with the tree trunk surface and that the center of the toothed ring 100 is basically coincident with the center of the tree trunk.

[0058] 4. Install the rubber tapper: After the track device is installed and debugged, engage the drive mechanism of the rubber tapper with the meshing teeth 110 on the outer ring of the gear ring 100 so that the rubber tapper can run stably along the track and perform automatic rubber tapping operations.

[0059] During the operation of the rubber tapper, the meshing teeth 110 on the outer ring of the toothed ring 100 provide a stable running track for the tapper, while the inner ring's contact claws 20 and clamping teeth 120 work together to ensure a tight fit between the track and the tree trunk, preventing track deviation or loosening. When the rubber tapper needs to be used on rubber trees of different diameters or surface shapes, the track can be quickly adapted and installed simply by adjusting the extension distance of the contact claws 20 using the adjustment components, greatly improving the applicability and installation efficiency of the rubber tapper.

[0060] The elastic contraction mechanism of the contact claw 20 is as follows: when the contact claw 20 is facing the protrusion on the tree trunk, the protrusion presses against the claw body 21, pushing it to contract along the slide groove 42 into the housing 40. During this process, the contraction spring 46 is compressed, storing elastic potential energy; when the protrusion passes this position, the spring releases energy, pushing the contact claw 20 back to its original position, continuing to maintain a close fit with the tree trunk. This mechanism enables the contact claw 20 to dynamically yield and reset to irregular protrusions on the tree trunk surface, preventing the track from shifting or being damaged due to localized compression.

[0061] The detachable adaptation mechanism of the clamping teeth 120 lies in the fact that the clamping teeth 120 are detachably connected to the elastic ribs 130 via slots 1024, allowing users to flexibly disassemble or replace the clamping teeth 120 according to the condition of the tree trunk surface. Removing some clamping teeth 120 in areas with dense protrusions can prevent interference with the protrusions; when the trunk diameter varies significantly, replacing them with clamping teeth 120 of different sizes can enhance the clamping effect. This design improves the adaptability of the track device to complex tree shapes and extends its service life.

[0062] The auxiliary adjustment function of the detection component is that, through the cooperation of force sensor 48 and tension spring 49, the adhesion force between clamping tooth 120 and tree trunk can be monitored in real time, providing a quantitative reference for users to adjust the position of the adhesion claw 20, and further optimizing the adhesion accuracy and stability.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
