Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery technology, and more specifically, to an adjustable guide rail and a rubber tapping machine. Background Technology

[0002] In existing technology, rubber tappers are used to tap rubber trees and their movement is supported by guide rails. However, the irregular cross-sectional shape of rubber trees causes the guide rails to have inconsistent shapes when in contact with the tree, resulting in differences in the shape of the upper and lower parts of the guide rails. This inconsistency directly affects the operation of the equipment, causing uneven movement and reduced work efficiency. Furthermore, the inner side of the guide rails typically has multiple toothed structures for fixing them to the rubber tree, but this fixing method increases manufacturing and installation costs and makes it impossible to adjust the upper and lower guide rails to an approximately circular or consistent shape.

[0003] Therefore, there is an urgent need to design a new type of guide rail to solve the problems of existing guide rails being unable to effectively adapt to the irregularities of the rubber tree surface and the high cost of guide rails. Utility Model Content

[0004] This invention aims to solve the problem in existing technology where the irregular cross-sectional shape of the rubber resin causes inconsistencies in the shape of the upper and lower guide rails, resulting in uneven equipment operation. By incorporating multiple adjustable fixing components within the guide rail, the shape of the guide rail can be effectively adjusted to approximate a circle, ensuring consistency between the upper and lower guide rails. This improves the operational stability and smoothness of the equipment, thereby enhancing work efficiency.

[0005] To achieve the above objectives, this utility model provides an adjustable guide rail, comprising: a guide rail body, the guide rail body including an inner ring wall and an outer ring wall, the outer ring wall having teeth that can engage in transmission; and adjusting members, a plurality of adjusting members disposed on the inner ring wall and abutting against the surface of the rubber tree, to adjust the guide rail body to adapt to the shape contour of different rubber trees and to adjust the clamping force between the guide rail body and the rubber tree; wherein, the adjusting member includes a top support member and a driving member that cooperates with the top support member, the driving member rotating to move the top support member toward or away from the surface of the rubber tree.

[0006] Furthermore, the top support is provided with a first threaded post, and the drive component is provided with a second threaded post, with the first threaded post and the second threaded post cooperating and connecting with each other.

[0008] Furthermore, the top support is provided with several top teeth, which are fixedly connected to the first threaded post; the top teeth abut against the surface of the rubber tree.

[0009] Furthermore, at least some of the top teeth are provided with a number of protruding pins; and / or the surface of the top teeth on the top support near the end of the guide rail body is a first guide surface, and the first guide surface has an arc-shaped structure.

[0010] Furthermore, the inner ring wall is provided with an installation part, and the first threaded column is slidably connected to the installation part.

[0011] Furthermore, the interior of the first threaded column is a hollow structure, the inner wall of the first threaded column is provided with a first sliding part, and the mounting part is provided with a second sliding part that cooperates with the first sliding part; and / or the interior of the first threaded column is a hollow structure, the inner wall of the first threaded column is provided with a first limiting part, and the mounting part is provided with a second limiting part that cooperates with the first limiting part.

Detailed Implementation

[0034] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0035] An embodiment of this utility model provides an adjustable guide rail, which includes: a guide rail body 100, the guide rail body 100 including an inner ring wall 110 and an outer ring wall 120, the outer ring wall 120 being provided with teeth 121 that can be engaged for transmission; and adjusting members 200, a plurality of adjusting members 200 being disposed on the inner ring wall 110 and abutting against each other on the surface of the rubber tree, so as to adjust the guide rail body 100 to adapt to the shape contour of different rubber trees and adjust the clamping force between the guide rail body 100 and the rubber tree; wherein, the adjusting member 200 includes a top support member 210 and a driving member 220 cooperating with the top support member 210, the driving member 220 driving the top support member 210 to move towards or away from the surface of the rubber tree by rotation.

[0036] like Figure 1-3 As shown, this utility model provides an adjustable guide rail, with several adjusting members 200 disposed on the inner ring wall 110 of the guide rail body 100 for adjusting the shape or position of the guide rail body 100. The adjusting members 200 are in contact with the surface of the resin, and the clamping force between the guide rail body 100 and the resin is adjusted by regulating the contact pressure between the adjusting members 200 and the resin. Specifically, the driving member 220 drives the movement of the top support member 210, which is slidably connected to adjust the distance between the guide rail and the surface of the resin.

[0037] Existing guide rails typically have several tooth-like structures on their inner side to help fix the guide rail to the rubber tree. However, this design not only increases manufacturing costs but also fails to effectively adjust the upper and lower guide rails to a consistent shape. The adjustable guide rail design in this technical solution aims to solve the problem of uneven roundness and coaxiality of the guide rail when it contacts the rubber tree surface due to the irregular shape of the rubber tree surface, thus affecting the stability and smoothness of the equipment's operation. By installing multiple adjusting components 200 on the inner ring wall 110 of the guide rail instead of other fixing components in the prior art, and by adjusting the relative positions of these adjusting components 200, the roundness and coaxiality of the guide rail can be flexibly adjusted, ensuring more uniform contact between the guide rail and the rubber tree.

[0038] It should be noted that several adjusting components 200 are evenly distributed on the guide rail body 100, and the two ends of the guide rail body 100 are provided with the adjusting components 200, so as to avoid deformation caused by the tightening of the guide rail.

[0039] like Figure 1As shown, the top support 210 is part of the adjusting member 200, and its main function is to adjust the contact pressure or distance between the guide rail and the surface of the glue tree through physical contact. The driving member 220 cooperates with the top support 210. The driving member 220 drives the top support 210 to move in a specific direction by rotation or other driving methods. Specifically, the rotation of the driving member 220 can move the top support 210 closer to or further away from the surface of the glue tree, thereby adjusting the installation firmness or contact state between the guide rail body 100 and the glue tree.

[0040] The drive component 220 and the top support component 210, through mechanical cooperation, can adjust the pressure of the guide rail by rotation without the need for tools, thereby adapting to the irregular shape of the rubber tree surface. This design can greatly improve the convenience and efficiency of equipment adjustment, especially when frequent adjustments are required.

[0041] In some embodiments of this application, the top support 210 is provided with a first threaded post 211, and the drive member 220 is provided with a second threaded post 221. The first threaded post 211 and the second threaded post 221 are connected to each other.

[0042] like Figure 4 , 6 As shown, the top support 210 and the drive component 220 are connected by a threaded connection. A first threaded post 211 on the top support 210 engages with a second threaded post 221 on the drive component 220, and the rotation of the thread drives the top support 210 to move axially. Specifically, rotating the second threaded post 221 of the drive component 220 causes it to engage with the first threaded post 211, pushing the top support 210 to move axially, thereby adjusting the clamping force or contact distance between the guide rail and the adhesive tree. Compared to traditional manual adjustment or simple sliding structures, the threaded structure not only provides higher precision and stability but also reduces errors caused by human operation.

[0043] In some embodiments of this application, the surface of the first threaded post 211 is provided with a first thread 212, and the inner wall of the second threaded post 221 is provided with a second thread 222; wherein, the first threaded post 211 is embedded in the hollow interior of the second threaded post 221.

[0044] like Figure 5 , 7As shown, the first threaded post 211 and the second threaded post 221 are nested together, and the adjustment function of the drive member 220 and the top support member 210 is achieved through threaded engagement. Specifically, the first threaded post 211 is embedded in the hollow part of the second threaded post 221. Through the mutual meshing of the threads, when the drive member 220 rotates, it will drive the top support member 210 to move precisely linearly along the thread axis. This structure allows the distance between the top support member 210 and the resin surface to be smoothly and precisely controlled by rotating the drive member 220, thereby adjusting the clamping force or contact state of the guide rail.

[0045] The interaction between the first threaded post 211 and the second threaded post 221 not only improves the adjustment accuracy but also ensures high stability and load-bearing capacity through the threaded embedding design. Compared with traditional connection methods, this embedded threaded connection design has advantages in terms of control force and stability.

[0046] In some embodiments of this application, the top support 210 is provided with a plurality of top teeth 213, the top teeth 213 being fixedly connected to the first threaded post 211; the top teeth 213 abut against the surface of the resin.

[0047] like Figure 4 As shown, the support member 210 is provided with multiple teeth 213. The function of these teeth 213 is to provide support or clamping force through contact with the surface of the rubber tree. The number and shape of the teeth 213 can be designed to optimize the contact with the rubber tree surface and ensure uniform pressure. Those skilled in the art can select an appropriate number and shape of teeth 213 according to their needs. The rotation of the first threaded post 211 can drive the teeth 213 to move toward or contact the surface of the rubber tree through the thread mechanism, thereby achieving pressure or support on the rubber tree. The way the teeth 213 contact the surface of the rubber tree ensures that the pressure can be evenly distributed on the surface of the rubber tree, avoiding problems such as damage to the surface of the rubber tree or uneven contact caused by excessive pressure at a single point.

[0048] In one embodiment of this utility model, there are four cusps 213, which are symmetrically distributed relative to the guide rail body 100. The cusps 213 have a certain inclination angle on the side near the resin surface to increase the contact area between the cusps 213 and the resin surface, thereby improving the force-bearing effect.

[0049] In some embodiments of this application, at least a portion of the top teeth 213 are provided with a plurality of protruding pins 214; and / or the surface of the top teeth 213 on the top support 210 near the end of the guide rail body 100 is a first guide surface 215, and the first guide surface 215 has an arc-shaped structure.

[0050] like Figure 5As shown, the surface of the tooth 213 is provided with several protrusions 214, the purpose of which is to increase the contact friction between the tooth 213 and the surface of the resin or to provide additional gripping force, which can help enhance the contact stability between the tooth 213 and the surface of the resin, and improve the fixation and reliability of the equipment.

[0051] like Figure 12 As shown, the teeth 213 of the first guide surface 215 are mainly located on the top support member 210 near the end of the guide rail body 100. The arc-shaped structure design allows the teeth 213 to provide a certain guiding effect when contacting the resin surface, helping to guide the teeth 213 to make smoother contact with the resin surface. Specifically, a top support member 210 is provided with at least four teeth 213. On the top support member 210 near the end of the guide rail body 100, some teeth 213 are provided with protruding nails 214, and some teeth 213 are designed as arc-shaped first guide surfaces 215 to facilitate guide rail tightening.

[0052] It should be noted that those skilled in the art can select the appropriate shape and number of protruding pins 214 according to their needs; the specific arc-shaped structure of the first guide surface 215 is such that its slope gradually decreases towards the end of the guide rail, thereby reducing the resistance generated when the guide rail is tightened.

[0053] In some embodiments of this application, the inner ring wall 110 is provided with a mounting portion 111, and the first threaded post 211 is slidably connected to the mounting portion 111.

[0054] like Figure 2-4 As shown, the mounting portion 111 is disposed on the inner ring wall 110 for supporting and fixing the first threaded post 211. The mounting portion 111 provides a slidable fixed position for the first threaded post 211, allowing it to move along a specific trajectory. The sliding connection design allows the first threaded post 211 to slide freely within the mounting portion 111, thereby improving the flexibility of the device. Users can adjust the position of the first threaded post 211 as needed, which helps to achieve more precise adjustments, especially in situations requiring fine-tuning of applied pressure or position.

[0055] Due to the sliding connection design, the requirements for components during equipment manufacturing are relatively simple, eliminating the need for overly complex positioning or fixing structures. The design of the mounting section 111 facilitates manufacturing and assembly, reducing production costs and complexity. Furthermore, this design also facilitates equipment maintenance and component replacement, reducing the difficulty and cost of equipment repair.

[0056] In some embodiments of this application, the interior of the first threaded post 211 is hollow, the inner wall of the first threaded post 211 is provided with a first sliding part 216, and the mounting part 111 is provided with a second sliding part 112 that cooperates with the first sliding part 216; and / or the interior of the first threaded post 211 is hollow, the inner wall of the first threaded post 211 is provided with a first limiting part 217, and the mounting part 111 is provided with a second limiting part 113 that cooperates with the first limiting part 217.

[0057] like Figure 8-11 As shown, the design of the first sliding part 216 and the second sliding part 112 cooperates to allow the top support 210 to slide and connect with the mounting part 111. Then, the driving part 220 drives the top support 210 to move closer to or away from the resin surface. This can precisely guide the movement trajectory of the top support 210, ensuring a smoother and more stable sliding process, reducing friction and wear, and extending service life. The cooperation of the first limiting part 217 and the second limiting part 113 effectively prevents excessive sliding or detachment of the components during use, ensuring that the top support 210 moves within a predetermined stroke range during the rotation or sliding of the threaded column, increasing the safety and stability of the device.

[0058] It should be noted that the mounting part 111 has a columnar structure, and its shape and size are adapted to the hollow structure of the first threaded post 211, thereby ensuring that the two components can slide relative to each other. The second sliding part 112 and the second limiting part 113 are arranged opposite each other. One of the first sliding part 216 and the second sliding part 112 is a groove, and the other is a rail. The groove and the rail cooperate to slide and connect, thereby realizing the sliding connection of the top support 210 relative to the mounting part 111. The second limiting part 113 is located at a certain position on the mounting part 111. When the top support 210 moves towards the glue tree to this position, the first limiting part 217 and the second limiting part 113 abut against each other, and the top support 210 stops moving.

[0059] The mounting section 111 in this embodiment provides two different structures, such as Figure 8-9 As shown, the second limiting part 113 is provided on one side of the mounting part 111, and the second sliding part 112 is provided on the opposite side of the mounting part 111; Figure 10 As shown, the second limiting part 113 is provided on one side of the mounting part 111, and the second sliding part 112 is provided on the opposite side of the mounting part 111. The protruding wall surface of the second sliding part 112 is also provided with a groove, which helps to increase the stability during sliding. Furthermore, as... Figure 10 The mounting portion 111 shown can be provided at both ends of the guide rail body 100 to ensure the stability of the engagement between the mounting portion 111 and the top support 210 when the guide rail is tightened. Those skilled in the art can design the shapes of the corresponding first limiting portion 217 and first sliding portion 216 according to the specific structure of the mounting portion 111.

[0060] In one embodiment of the present invention, the top support 210 is provided with a closed configuration at its relative center position to prevent dirt generated during rubber tapping from entering the cavity of the first threaded post 211, thereby reducing the resistance generated when the top support 210 slides relative to the mounting part 111.

[0061] In some embodiments of this application, a rib 114 is provided on the guide rail body 100 near the mounting part 111.

[0062] like Figure 9 As shown, the design of the rib 114 enhances the structural strength and rigidity of the guide rail body 100, improving its stability and durability under load. It also optimizes the overall stress distribution, preventing deformation or damage to the guide rail due to uneven stress during operation. Specifically, the rib 114 protrudes from the inner ring wall 110 and is located at least around the mounting portion 111. This avoids stress on the guide rail body 100 caused by the adjustment of the adjusting member 200 and improves the structural strength of the guide rail body 100. Those skilled in the art can design the specific shape of the rib 114 as needed.

[0063] In some embodiments of this application, the drive component 220 is provided with a knob 223, which is fixedly connected to the second threaded post 221.

[0064] like Figure 6 As shown, the drive unit 220 is equipped with a knob 223, which the user can rotate to move, adjust, or lock the drive unit 220. The knob 223 has a large contact surface, facilitating manual operation and is suitable for applications requiring frequent adjustment or fine control. The knob 223 is fixedly connected to the second threaded post 221, allowing rotation of the knob 223 to directly drive the second threaded post 221 to rotate or move. The distance between the top support 210 and the resin tree can be adjusted via the drive unit 220, thereby changing the distance between the guide rail and the surface of the resin tree.

[0065] It should be noted that the side of the knob 223 near the glue tree has a recessed structure. When the top support 210 and the drive component 220 are assembled and installed, the recessed structure of the knob 223 can accommodate at least part of the top tooth 213.

[0066] like Figure 11-12 As shown, a second guide surface 218 is provided on the side of the top support 210 near the recessed structure of the knob 223. The second guide surface 218 is located on the edge of the top support 210 and has an arc-shaped structure. When adjusting the knob 223, the setting of the second guide surface 218 can effectively prevent the top support 210 from rubbing against the knob 223, thus extending the service life of the adjusting part 200.

[0067] like Figure 13 As shown, multiple ribs 224 are provided on the other side of the knob 223, which helps to improve the structural strength of the knob 223.

[0068] An embodiment of this utility model also provides a rubber tapping machine, which includes the adjustable guide rail described above.

[0069] A rubber tapping machine is a mechanical device used for collecting and tapping rubber. It cuts the bark of rubber trees to collect sap. The core components of a rubber tapping machine include the tapping blade, guide rails, and drive system. Its main function is to guide the tapping blade to make precise cuts along the surface of the tree trunk.

[0070] In this technical solution, the rubber tapping machine is equipped with an adjustable guide rail. The design of this guide rail allows users to adjust its position or angle according to actual needs, thereby meeting different rubber tapping operation requirements. By setting multiple adjusting components 200 within the guide rail, the shape of the guide rail can be effectively adjusted to approximate a circle, ensuring the consistency of the upper and lower guide rails, thus improving the operational stability and smoothness of the equipment and increasing work efficiency.

[0071] While the present invention has been disclosed above, it is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
