A lawn compaction mold for ecological grass planting ditches in garden construction

Abstract

This utility model relates to the field of landscape engineering construction, specifically a lawn compaction mold for ecological grassed ditch construction. By incorporating rollers and a pull rod traction component, when the construction worker pulls the pull rod traction component, the rollers roll along with it. The rollers have an arc-shaped cross-section, perfectly conforming to the curve of the grassed ditch. This ensures uniform contact between the rollers and the lawn and soil during compaction, and the rollers apply uniform pressure to the lawn during movement. This avoids the localized loosening or over-compaction caused by uneven force during manual compaction. It effectively solves the problem that in the lawn laying and compaction stage, construction workers often use shovels to compact the lawn to ensure close contact between the lawn roots and the soil. However, because grassed ditches typically have an arc-shaped structure, manual compaction is difficult to completely conform to the curve of the ditch, resulting in poor molding effects and the grassed ditch being prone to unevenness or localized loosening.

Description

Technical Field

[0001] This utility model relates to the field of landscape engineering construction, specifically a lawn compaction mold for building ecological grass planting ditches in gardens. Background Technology

[0002] With the accelerating pace of urbanization and the increasing emphasis on the ecological environment, landscape construction is playing an increasingly important role in urban planning. In landscape construction, it is common to build ecological grassed ditches. As an important component of the landscape, these ditches not only collect, transport, and purify rainwater, effectively reducing surface runoff and mitigating the risk of urban flooding, but also add a natural and aesthetically pleasing effect to the landscape, creating a more harmonious and pleasant ecological environment.

[0003] During the construction of grassed drainage ditches, including the lawn laying and compaction stage, construction workers usually use shovels to compact the soil so that the lawn roots can be in close contact with the soil. However, since grassed drainage ditches usually have an arc-shaped structure, manual compaction is difficult to completely conform to the curve of the ditch, resulting in poor shaping effect. Furthermore, grassed drainage ditches are prone to unevenness or local loosening.

[0004] This utility model was proposed in response to the shortcomings of the existing technology. Utility Model Content

[0005] Regarding the aforementioned issue in the lawn compaction process, construction workers often use shovels to compact the soil, ensuring close contact between the lawn roots and the soil. However, because grazing trenches typically have an arc-shaped structure, manual compaction makes it difficult to perfectly conform to the curve of the trench, resulting in poor compaction and unevenness or localized loosening of the grazing trenches. The technical solution adopted by this utility model to solve this problem is as follows:

[0006] A lawn compaction mold for building ecological grass planting ditches in gardens includes a mold body, the mold body including a roller for compacting lawn and a pull rod traction assembly movably connected to the roller. The roller has an arc-shaped cross-section, and when the pull rod traction assembly is moved by force, the roller moves with the pull rod traction assembly.

[0007] Furthermore, the pull rod traction assembly includes a pull rod mechanism and an adjustment mechanism located between the pull rod mechanism and the roller and movably connected to the roller, the adjustment mechanism being used to adjust the relative distance between the pull rod mechanism and the roller.

[0008] Furthermore, the roller is formed by a steel plate enclosure, and the inner sidewall of the roller is provided with a first reinforcing rib and a second reinforcing rib, which are arranged in a crisscross pattern.

[0009] Furthermore, the first reinforcing ribs are provided in multiple forms and extend along the axial direction of the roller, and the multiple first reinforcing ribs are spaced apart along the circumferential direction of the roller.

[0010] Furthermore, the second reinforcing ribs are provided in multiple forms and extend along the circumferential direction of the roller, and the multiple second reinforcing ribs are spaced apart along the axial direction of the roller.

[0011] Furthermore, the adjustment mechanism includes an adjustment telescopic rod and a pin. The adjustment telescopic rod has a plurality of pin holes, which are spaced apart along the extension direction of the adjustment telescopic rod. The pull rod mechanism has a plurality of connecting holes corresponding to the pin holes. The pin holes are connected to the connecting holes through the pins, so that the pull rod mechanism and the adjustment telescopic rod are detachably connected.

[0012] Furthermore, a connecting bearing is provided between the adjusting telescopic rod and the roller, and the adjusting telescopic rod is movably connected to the roller through the connecting bearing.

[0013] Furthermore, the roller has a hollow structure.

[0014] Furthermore, the roller includes a first compaction surface, a second compaction surface, and a third compaction surface located between the first compaction surface and the second compaction surface, wherein the third compaction surface is inclinedly connected to the first compaction surface and the second compaction surface and has rounded corners.

[0015] Furthermore, the lever mechanism includes a first lever, a second lever symmetrically arranged with respect to the first lever, and a third lever located between the first lever and the second lever, wherein the third lever is perpendicularly connected to both the first lever and the second lever.

[0016] The beneficial effects of this utility model are as follows:

[0017] This invention features a roller for compacting lawns and a pull rod traction assembly connected to the roller. When the worker pulls the pull rod traction assembly, the roller rolls along with it. The roller's cross-section is arc-shaped, perfectly conforming to the curve of the planting trench. This ensures uniform contact between the roller and the lawn and soil during compaction, and the roller applies uniform pressure to the lawn as it moves. This avoids the problem of uneven compaction or over-compaction caused by uneven force during manual compaction. It effectively solves the problem that in lawn compaction, workers often use shovels to compact the lawn to ensure close contact between the roots and the soil. However, since planting trenches usually have an arc-shaped structure, manual compaction is difficult to completely conform to the curve of the trench, resulting in poor compaction and unevenness or localized looseness in the planting trench.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0019] Figure 1 This is a schematic diagram of the structure of the mold body of this utility model;

[0020] Figure 2 This is one of the cross-sectional schematic diagrams of the mold body of this utility model;

[0021] Figure 3 This is the second cross-sectional view of the mold body of this utility model. Detailed Implementation

[0022] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] like Figures 1 to 3 The illustrated lawn compaction mold for building ecological grass planting ditches includes a mold body 1. The mold body 1 includes a roller 2 for compacting lawn and a pull rod traction assembly 3 movably connected to the roller 2. The roller 2 has an arc-shaped cross-section. When the pull rod traction assembly 3 is subjected to force and moves, the roller 2 moves with the pull rod traction assembly 3.

[0024] This invention features a roller for compacting lawns and a pull rod traction assembly connected to the roller. When the worker pulls the pull rod traction assembly, the roller rolls along with it. The roller's cross-section is arc-shaped, perfectly conforming to the curve of the planting trench. This ensures uniform contact between the roller and the lawn and soil during compaction, and the roller applies uniform pressure to the lawn as it moves. This avoids the problem of uneven compaction or over-compaction caused by uneven force during manual compaction. It effectively solves the problem that in lawn compaction, workers often use shovels to compact the lawn to ensure close contact between the roots and the soil. However, since planting trenches usually have an arc-shaped structure, manual compaction is difficult to completely conform to the curve of the trench, resulting in poor compaction and unevenness or localized looseness in the planting trench.

[0025] Furthermore, by setting up the tie rod traction component 3, construction workers can easily move the roller 2 to continuously and evenly compact the lawn. Compared with the traditional method of compacting with a shovel, this method can improve construction efficiency and effectively shorten construction time.

[0026] Furthermore, the design of the tie rod traction component 3 conforms to ergonomic principles and is easy to operate. Construction workers do not need to frequently bend over or use shovels to forcefully strike, which can significantly reduce labor intensity and improve construction comfort.

[0027] Optionally, in some embodiments, the roller 2 is provided with a connecting rod, which passes through the roller 2 and extends to both sides of the roller 2. The two sides of the connecting rod are respectively connected to the pull rod traction assembly 3. When the construction personnel pull the pull rod traction assembly 3, the connecting rod and the pull rod traction assembly 3 move synchronously, thereby driving the roller 2 to roll.

[0028] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, the roller 2 is provided with connecting bearings 5 ​​on both sides near the pull rod traction assembly 3, and the pull rod traction assembly 3 is movably connected to both sides of the roller 2 through the connecting bearings 5.

[0029] Furthermore, the arc-shaped structure of the grass-planted ditch matches the arc-shaped surface of the roller 2. In the process of constructing the grass-planted ditch, a combination of manual and mechanical methods is usually used for excavation to ensure that the curvature of the ditch matches the arc-shaped surface of the roller 2.

[0030] like Figures 1 to 3 The pull rod traction assembly 3 shown includes a pull rod mechanism 31 and an adjustment mechanism 32 located between the pull rod mechanism 31 and the roller 2 and movably connected to the roller 2. The adjustment mechanism 32 is used to adjust the relative distance between the pull rod mechanism 31 and the roller 2.

[0031] Furthermore, different construction workers have different strengths and operating habits. By setting up the adjustment mechanism 32 to change the relative distance between the pull rod mechanism 31 and the roller 2, the lever arm length during construction can be changed. For construction workers with less strength, the relative distance between the pull rod mechanism 31 and the roller 2 can be appropriately shortened to reduce the lever arm. In this way, the force required to pull the pull rod mechanism 31 is relatively small, and the operation is easier. Construction workers with greater strength can appropriately increase the relative distance between the pull rod mechanism 31 and the roller 2 to obtain a better operating feel and control over the roller 2.

[0032] Optionally, in some embodiments, the adjusting mechanism 32 is sleeved on the outer wall of the pull rod mechanism 31 so that the pull rod mechanism 31 can move relative to the adjusting mechanism 32. The pull rod mechanism 31 is provided with a buckle, and the adjusting mechanism 32 is provided with a plurality of slots that engage with the buckle. When the construction personnel need to adjust the relative distance between the pull rod mechanism 31 and the roller 2, they pull the pull rod mechanism 31, and the pull rod mechanism 31 moves relative to the adjusting mechanism 32. When the pull rod mechanism 31 is adjusted to a suitable position, the buckle engages with the slots at the corresponding positions, thereby fixing the relative position of the pull rod mechanism 31 and the adjusting mechanism 32.

[0033] Optionally, in some embodiments, the adjusting mechanism 32 is sleeved on the outer wall of the pull rod mechanism 31 so that the pull rod mechanism 31 can move relative to the adjusting mechanism 32. The pull rod mechanism 31 is provided with a first threaded hole, and the adjusting mechanism 32 is provided with a plurality of second threaded holes that are threadedly connected to the first threaded hole. When the construction personnel need to adjust the relative distance between the pull rod mechanism 31 and the roller 2, they pull the pull rod mechanism 31, and the pull rod mechanism 31 moves relative to the adjusting mechanism 32. When the pull rod mechanism 31 is adjusted to a suitable position, the first threaded hole and the second threaded hole are connected simultaneously by screws, thereby fixing the relative position of the pull rod mechanism 31 and the adjusting mechanism 32.

[0034] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, the adjusting mechanism 32 is sleeved on the outer wall of the pull rod mechanism 31 so that the pull rod mechanism 31 can move relative to the adjusting mechanism 32. The pull rod mechanism 31 is provided with several connecting holes, and the adjusting mechanism 32 is provided with several pin holes 3211 corresponding to the connecting holes. When the construction personnel need to adjust the relative distance between the pull rod mechanism 31 and the roller 2, they pull the pull rod mechanism 31, and the pull rod mechanism 31 moves relative to the adjusting mechanism 32. When the pull rod mechanism 31 is adjusted to a suitable position, the pin holes 3211 and the connecting holes are connected simultaneously by the pins 322, thereby fixing the relative position of the pull rod mechanism 31 and the adjusting mechanism 32.

[0035] like Figures 1 to 3 The roller 2 shown is formed by steel plates. The inner sidewall of the roller 2 is provided with a first reinforcing rib 41 and a second reinforcing rib 42, which are arranged in a crisscross pattern.

[0036] Furthermore, the first reinforcing rib 41 and the second reinforcing rib 42 can significantly improve the deformation resistance of the roller 2, so that the roller 2 can withstand greater pressure without deformation when compacting the lawn. The crisscrossing layout of the first reinforcing rib 41 and the second reinforcing rib 42 further optimizes the structural stability and ensures that the roller 2 maintains good working performance during long-term use.

[0037] Furthermore, by providing a first reinforcing rib 41 and a second reinforcing rib 42 inside the steel plate roller 2, the strength of the roller 2 can be improved without increasing the wall thickness, thereby avoiding the increase in weight caused by increasing the wall thickness. While ensuring the function, the overall weight of the roller 2 is reduced, making it easier to operate and move.

[0038] Optionally, in some embodiments, the first reinforcing rib 41 is arranged along the inner sidewall of the roller 2 and is wavy. The first reinforcing rib 41 is parallel to the axis of the roller 2. The second reinforcing rib 42 is also wavy and is arranged perpendicular to the first reinforcing rib 41. The first reinforcing rib 41 and the second reinforcing rib 42 are interlaced on the inner sidewall of the roller 2 to form a wavy grid structure, which is beneficial to better absorb impact and vibration and helps to enhance the fatigue resistance of the roller 2.

[0039] Furthermore, as a preferred embodiment of the present invention and not a limitation thereof, multiple first reinforcing ribs 41 are provided and extend along the axial direction of the roller 2, and several first reinforcing ribs 41 are spaced apart along the circumferential direction of the roller 2; multiple second reinforcing ribs 42 are provided and extend along the circumferential direction of the roller 2, and several second reinforcing ribs 42 are spaced apart along the axial direction of the roller 2.

[0040] Specifically, roller 2 is a steel plate with a thickness of 5 mm.

[0041] like Figures 1 to 3 The first reinforcing rib 41 shown is provided in multiple ways and extends along the axial direction of the roller 2. Several first reinforcing ribs 41 are spaced apart along the circumferential direction of the roller 2.

[0042] Furthermore, the multiple first reinforcing ribs 41 extend along the axial direction of the roller, which can significantly enhance the load-bearing capacity of the roller 2 in the axial direction, so that the roller 2 can better maintain the stability of its shape and size when subjected to axial pressure, and prevent the roller 2 from undergoing axial deformation or damage.

[0043] Furthermore, by arranging multiple first reinforcing ribs 41 at intervals along the circumference of the roller 2, the concentrated load on the roller 2 can be distributed over a larger area, thereby reducing the local stress level. This helps to reduce stress concentration in the roller 2 during the stress process and improves the reliability and durability of the roller 2.

[0044] Furthermore, by setting the first reinforcing ribs 41 at intervals, the amount of material used can be reduced while ensuring strength, thereby reducing the weight of the roller 2.

[0045] Specifically, the first reinforcing rib 41 is made of steel.

[0046] like Figures 1 to 3 The second reinforcing rib 42 shown is provided in multiple ways and extends along the circumferential direction of the roller 2, and the multiple second reinforcing ribs 42 are spaced apart along the axial direction of the roller 2;

[0047] Furthermore, multiple second reinforcing ribs 42 extend along the circumference of the roller 2, which can significantly enhance the load-bearing capacity of the roller 2 in the circumferential direction, so that the roller 2 can better maintain its shape and size stability when subjected to circumferential pressure or torque, and prevent the roller 2 from undergoing circumferential deformation or twisting.

[0048] Furthermore, by providing multiple second reinforcing ribs 42 at intervals along the axial direction of the roller 2, the stress inside the roller 2 can be further dispersed, the local stress level can be reduced, and the stress concentration phenomenon of the roller 2 during the stress process can be reduced, thereby improving the reliability and durability of the roller 2.

[0049] Furthermore, by setting the second reinforcing ribs 42 at intervals, the amount of material used can be reduced while ensuring strength, thereby reducing the weight of the roller 2.

[0050] Specifically, the second reinforcing rib 42 is made of steel.

[0051] like Figures 1 to 3 The adjustment mechanism 32 shown includes an adjustment telescopic rod 321 and a pin 322. The adjustment telescopic rod 321 has a plurality of pin holes 3211, which are spaced apart along the extension direction of the adjustment telescopic rod 321. The pull rod mechanism 31 has a plurality of connecting holes corresponding to the pin holes 3211. The pin holes 3211 are connected to the connecting holes through the pins 322, so that the pull rod mechanism 31 and the adjustment telescopic rod 321 are detachably connected.

[0052] Furthermore, by adjusting the telescopic function of the telescopic rod 321, the user can easily adjust the overall length of the tie rod mechanism 31 after it is connected to the telescopic rod 321, so that the mold body 1 can adapt to different working environments and operational requirements.

[0053] Furthermore, the design of the pin hole 3211, the connecting hole, and the pin 322 makes the connection between the pull rod mechanism 31 and the adjusting telescopic rod 321 simple and quick. Users only need to insert the pin 322 into the corresponding pin hole 3211 and the connecting hole to achieve a firm connection between the two. Similarly, the disassembly process is also very simple; just pull out the pin 322.

[0054] Furthermore, the connection method of the pin hole 3211, the connecting hole, and the pin 322 has high stability. The pin 322 can be firmly locked in the pin hole 3211 and the connecting hole to prevent relative movement or loosening between the pull rod mechanism 31 and the adjusting telescopic rod 321 during use.

[0055] Furthermore, the tie rod mechanism 31 is connected to the adjusting telescopic rod 321 via a pin 322, allowing users to quickly disassemble or install components as needed, facilitating maintenance and replacement. Secondly, the detachable design allows the mold body 1 to be disassembled into smaller parts during transportation and storage, which helps reduce space occupation and effectively lowers transportation costs.

[0056] Optionally, the adjusting telescopic rod 321 is a square steel tube.

[0057] like Figures 1 to 3 A connecting bearing 5 is provided between the adjusting telescopic rod 321 and the roller 2 shown, and the adjusting telescopic rod 321 is movably connected to the roller 2 through the connecting bearing 5;

[0058] Furthermore, the connecting bearing 5 can provide support and rotation, allowing the roller 2 to rotate smoothly relative to the adjusting telescopic rod 321. By reducing the coefficient of friction between the adjusting telescopic rod 321 and the roller 2, the connecting bearing 5 can significantly reduce the wear of the roller 2 during rotation, effectively extending the service life of the roller 2 and the adjusting telescopic rod 321.

[0059] Furthermore, the connecting bearing 5, as the connecting part between the adjusting telescopic rod 321 and the roller 2, can withstand large radial and axial loads, which helps to enhance the connection strength between the roller 2 and the adjusting telescopic rod 321, and helps to prevent the roller 2 from loosening or falling off during the stress process, effectively improving the stability and safety of the entire equipment.

[0060] Specifically, an installation mechanism is provided between the adjusting telescopic rod 321 and the connecting bearing 5. The installation mechanism includes an adapter and a mounting bolt 51. The adjusting telescopic rod 321 is detachably connected to the connecting bearing 5 through the installation mechanism, so that users can easily connect the adjusting telescopic rod 321 to the connecting bearing 5 or remove it. This simplifies the installation and disassembly process, helps reduce the difficulty of operation, and effectively improves work efficiency.

[0061] like Figures 1 to 3 The roller 2 shown is a hollow structure;

[0062] Furthermore, in lawn compaction operations, if the roller 2 is too heavy, it will be difficult for the operator to push or manipulate the mold body 1, especially during long-term operations, which will greatly increase the operator's labor intensity. The hollow structure of the roller 2 can significantly reduce its own weight, making it easier for the operator to push the roller 2, which helps to reduce the difficulty of operation and effectively improve work efficiency.

[0063] Furthermore, adopting a hollow structure can reduce the amount of material used while ensuring the strength and performance of roller 2, which helps to reduce production costs.

[0064] like Figures 1 to 3 The roller 2 shown includes a first compaction surface 21, a second compaction surface 22, and a third compaction surface 23 located between the first compaction surface 21 and the second compaction surface 22. The third compaction surface 23 is inclinedly connected to the first compaction surface 21 and the second compaction surface 22 with rounded corners.

[0065] Furthermore, the rounded corner connection method avoids direct contact between sharp edges and the lawn. If there were right angles or sharp edges during the rolling of roller 2, it might cause damage such as cutting or tearing to the lawn, affecting its appearance and growth. The rounded corner design makes the contact between roller 2 and the lawn softer, reducing mechanical damage to the lawn and promoting its healthy growth.

[0066] Furthermore, the rounded corners effectively disperse stress and prevent stress concentration at the joints, which helps reduce the risk of fatigue damage and cracking caused by stress concentration, thereby increasing the service life of roller 2.

[0067] Furthermore, the rounded corners eliminate sharp edges, making the surface of roller 2 smoother and preventing cuts or scratches to operators during use. This improves the safety and aesthetics of the mold body 1.

[0068] like Figures 1 to 3 The lever mechanism 31 shown includes a first lever 311, a second lever 312 symmetrically arranged with the first lever 311, and a third lever 313 located between the first lever 311 and the second lever 312. The third lever 313 is perpendicularly connected to the first lever 311 and the second lever 312 respectively.

[0069] Furthermore, when using the mold body 1 to compact the lawn, the operator will apply force through the pull rod mechanism 31 to push or pull the roller 2. The first pull rod 311 and the second pull rod 312 are symmetrically arranged, which can evenly distribute the force applied by the operator to both sides of the roller 2, avoiding excessive force on one side that could cause the roller 2 to shift or be damaged. Secondly, the third pull rod 313 is vertically connected to the first pull rod 311 and the second pull rod 312 respectively, which further enhances the structural strength of the entire pull rod mechanism 31, enabling the force to be transmitted to the roller 2 more effectively and improving the compaction efficiency of the roller 2.

[0070] Furthermore, the symmetrical first tie rod 311 and second tie rod 312, along with the vertically connected third tie rod 313, form a stable frame structure, which helps maintain the balance of the mold body 1 during operation. When pushing or pulling the mold body 1, the operator can more easily control the forward direction and speed of the mold body 1, reducing the possibility of the mold body 1 swaying or deviating to the left or right, and improving the accuracy and stability of the operation.

[0071] Optionally, the first tie rod 311, the second tie rod 312, and the third tie rod 313 are all square steel tubes.

[0072] Optionally, the first tie rod 311, the second tie rod 312, and the third tie rod 313 can be connected by welding.

[0073] Optionally, the first pull rod 311, the second pull rod 312, and the third pull rod 313 can be connected by a threaded connection.

[0074] The implementation method of Example 1 is as follows:

[0075] A lawn compaction mold for ecological vegetated ditch construction includes a mold body 1. The mold body 1 includes a roller 2 for compacting the lawn and a pull rod traction component 3 movably connected to the roller 2. When the construction worker pulls the pull rod traction component 3, the roller 2 rolls along with the pull rod traction component 3. The cross-section of the roller 2 is arc-shaped, which can perfectly fit the curve of the vegetated ditch, ensuring that the contact surface between the roller 2 and the lawn and soil is uniform during the compaction process. Moreover, the roller 2 can apply uniform pressure to the lawn during the movement, avoiding the situation of local loosening or over-compaction caused by uneven force during manual compaction. This effectively solves the problem that in the lawn laying and compaction stage, the construction worker often uses a shovel to compact the lawn so that the lawn roots are in close contact with the soil. However, since the vegetated ditch usually has an arc-shaped structure, it is difficult for manual compaction to completely fit the curve of the ditch, resulting in poor molding effect and the vegetated ditch is prone to unevenness or local loosening.

[0076] The roller 2 is formed by steel plates. The inner sidewall of the roller 2 is provided with a first reinforcing rib 41 and a second reinforcing rib 42. There are multiple first reinforcing ribs 41 that extend along the axial direction of the roller 2 and are spaced apart along the circumference of the roller 2. There are multiple second reinforcing ribs 42 that extend along the circumference of the roller 2 and are spaced apart along the axial direction of the roller 2.

[0077] The pull rod traction assembly 3 includes a pull rod mechanism 31 and an adjustment mechanism 32. The adjustment mechanism 32 includes an adjusting telescopic rod 321 and a pin 322. The adjusting telescopic rod 321 has several pin holes 3211, which are spaced apart along the extension direction of the adjusting telescopic rod 321. The pull rod mechanism 31 has several connecting holes corresponding to the pin holes 3211. The pin holes 3211 are connected to the connecting holes through the pins 322, thereby adjusting the relative distance between the pull rod mechanism 31 and the roller 2.

[0078] A connecting bearing 5 is provided between the adjusting telescopic rod 321 and the roller 2, and the adjusting telescopic rod 321 is movably connected to the roller 2 through the connecting bearing 5.

[0079] The implementation method of Example 2 is as follows:

[0080] The difference between Example 2 and Example 1 is that: a connecting rod is provided inside the roller 2, the connecting rod passes through the roller 2 and extends to both sides of the roller 2, and the two sides of the connecting rod are respectively connected to the pull rod traction assembly 3. When the construction personnel pull the pull rod traction assembly 3, the connecting rod and the pull rod traction assembly 3 move synchronously, thereby driving the roller 2 to roll.

[0081] The implementation method of Example 3 is as follows:

[0082] The difference between Example 3 and Example 1 is that the adjusting mechanism 32 is sleeved on the outer wall of the pull rod mechanism 31 so that the pull rod mechanism 31 can move relative to the adjusting mechanism 32. The pull rod mechanism 31 is provided with a buckle, and the adjusting mechanism 32 is provided with a number of slots that cooperate with the buckle. When the construction personnel need to adjust the relative distance between the pull rod mechanism 31 and the roller 2, they pull the pull rod mechanism 31, and the pull rod mechanism 31 moves relative to the adjusting mechanism 32. When the pull rod mechanism 31 is adjusted to a suitable position, the buckle and the corresponding slots cooperate to fix the relative position of the pull rod mechanism 31 and the adjusting mechanism 32.

[0083] The implementation method of Example 4 is as follows:

[0084] The difference between Example 4 and Example 1 is that the adjusting mechanism 32 is sleeved on the outer wall of the pull rod mechanism 31 so that the pull rod mechanism 31 can move relative to the adjusting mechanism 32. The pull rod mechanism 31 is provided with a first threaded hole, and the adjusting mechanism 32 is provided with a number of second threaded holes that are threadedly connected to the first threaded hole. When the construction personnel need to adjust the relative distance between the pull rod mechanism 31 and the roller 2, they pull the pull rod mechanism 31, and the pull rod mechanism 31 moves relative to the adjusting mechanism 32. When the pull rod mechanism 31 is adjusted to a suitable position, the first threaded hole and the second threaded hole are connected simultaneously by screws, thereby fixing the relative position of the pull rod mechanism 31 and the adjusting mechanism 32.

[0085] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments. Any technical extensions or re-creations made based on this utility model are protected by this utility model. The scope of protection of this utility model is defined by the claims.
