Description

Technical Field

[0001] This invention relates to the field of garden facilities, specifically to a buried ring-shaped root control device. Background Technology

[0002] In modern urban greening, various street trees and landscape tree pits are often planted along roadsides. These trees not only beautify the urban environment but also serve functions such as purifying the air, cooling the air, and providing shade. However, as trees grow, the expansion of their root systems can bring some problems that cannot be ignored. The natural expansion of tree roots can put pressure on the surrounding pavement, leading to cracks, depressions, and unevenness in the road surface. This not only affects the aesthetics and smoothness of the road but also poses a potential threat to the safety of pedestrians and vehicles.

[0003] The expansion of tree root systems can also damage underground infrastructure, such as pipes and cables, increasing the cost of urban maintenance and repair. Therefore, how to effectively control the growth of tree roots and prevent them from damaging ground paving and underground facilities has become an urgent problem to be solved in the fields of landscaping and municipal engineering.

[0004] In the prior art, some root control devices and methods have been proposed, such as using physical barriers and chemical agents to limit root expansion. However, these methods have certain limitations. Physical barriers may not completely prevent root penetration, while chemical agents may pollute the environment and require repeated application, increasing maintenance costs.

[0005] Therefore, developing a highly efficient, environmentally friendly, and low-maintenance root control device that can protect roads and infrastructure while maintaining the normal growth of trees is of great practical significance. Summary of the Invention

The solar panel is disposed on top of the middle cutting layer and above the upper sliding track.

[0016] Optionally, both the upper sliding track and the lower sliding track are provided with grooves, the upper pulley is connected to the motor module through a connecting member, and the upper pulley and the lower pulley are respectively disposed in the grooves corresponding to the upper sliding track and the lower sliding track.

[0017] Specifically, the outer protective layer includes a stainless steel box, which includes an outer side, a lower side, a left side, and a right side. The lower side, the left side, and the right side are respectively vertically and fixedly connected to the lower, left, and right sides of the outer side. The left side and the right side are respectively connected to the left and right ends of the middle cutting layer.

[0018] Specifically, the outer protective layer further includes: a pull-up drawer, the pull-up drawer including: a top panel, a left side panel, a right side panel and a bottom frame, the bottom frame being arranged parallel to the top panel, the upper ends of the left side panel and the right side panel being vertically fixedly connected to the two ends of the top panel respectively, and the lower ends of the left side panel and the right side panel being vertically fixedly connected to the lower end of the bottom frame respectively; the bottom frame is a box body with the top surface removed.

[0039] Example 1

[0040] like Figure 1 and Figure 2 As shown, a buried ring-shaped root control device is provided, including: multiple root control components, which are connected in sequence to form a ring structure, the roots of the tree are located inside the ring structure, and the ring structure is buried underground.

[0041] The root control component comprises, from the inside out, an inner protective layer 3, a middle cutting layer 2, and an outer protective layer 1. The inner protective layer 3 has root penetration holes for the tree roots to pass through, and the middle cutting layer 2 cuts off the penetrating roots.

[0042] "Buried type" refers to a device that is completely buried underground, without affecting the use or aesthetics of the surface. "Ring root control device" refers to a device that forms a closed ring structure, surrounding the roots of the tree. The number of root control components can be more than three; this embodiment uses four as an example, forming a rectangular ring structure.

[0043] The root control assembly is a unit used to control and guide the growth of tree roots. Each root control assembly can work independently and is connected to form an integral structure. The root penetration hole is a hole set in the inner protective layer 3 to allow the tree root to penetrate to the middle cutting layer 2, and the cutting device installed in the middle cutting layer 2 can cut off the penetrating tree root.

[0044] As tree roots grow, they penetrate through root penetration holes in the inner protective layer 3 and enter the central cutting layer 2. Once the roots enter the central cutting layer 2, the cutting device promptly severs them to prevent further expansion, thus protecting the ground paving and underground infrastructure from root damage. The outer protective layer 1 provides further protection, ensuring the stability and durability of the entire system.

[0045] Through this structural design, the present invention can effectively control the growth of tree roots, prevent them from damaging ground and underground facilities, and achieve harmonious coexistence between trees and urban infrastructure.

[0046] Example 2

[0047] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the central cutting layer 2 of the key component is described. The central cutting layer 2 includes: an upper sliding rail, a lower sliding rail, an upper pulley 13, a lower pulley, a motor module, and a cutting steel strip 14.

[0048] The upper sliding track and the lower sliding track are set in parallel; the upper pulley 13 moves horizontally along the upper sliding track, and the lower pulley moves horizontally along the lower sliding track; the motor module is connected to the upper pulley 13 or the lower pulley and drives it to move; the upper end of the cutting steel strip 14 is connected to the upper pulley 13 through the connecting member 16, and the lower end of the cutting steel strip 14 is connected to the lower pulley through the connecting member 16.

[0049] The motor module provides power so that the pulley and the cutting steel bar 14 can move along the track. The track provides the movement path for the pulley, ensuring that the cutting device can move smoothly along the predetermined route. The cutting steel bar 14 is moved horizontally by the track so that it can cut the protruding tree roots.

[0050] The motor module includes a solar panel 4, a battery module and a motor 12. The torque output shaft of the motor 12 is connected to the rotation bearing 15 of the upper pulley 13 or the lower pulley. Both the solar panel 4 and the motor 12 are electrically connected to the battery module. The solar panel 4 is located on top of the middle cutting layer 2 and above the upper sliding track.

[0051] Solar panel 4 converts solar energy into electrical energy to power the motor module. The battery module stores the electrical energy converted by solar panel 4 and provides power to motor 12 when needed. An additional transmission structure can be installed between the torque output shaft of motor 12 and the pulley, as long as transmission is possible.

[0052] Simultaneously, multiple connection structures are provided. One configuration allows 12 motors to drive the upper pulley 13, which in turn moves the cutting steel strip 14, which in turn pulls the lower pulley. Alternatively, 12 motors can drive the lower pulley, which in turn moves the cutting steel strip 14, which in turn pulls the upper pulley 13. Another configuration allows two motors 12 to simultaneously drive both the upper and lower pulleys, thereby causing the upper and lower pulleys to move the cutting steel strip 14.

[0053] Solar panel 4 converts solar energy into electrical energy and stores it in the battery module. When cutting is required, the battery module provides power to motor 12. The torque output shaft of motor 12 is connected to the rotation bearing 15 of the pulley, driving the pulley to move along the sliding track. The movement of the pulley causes the cutting steel bar 14 to move left and right, cutting the tree roots. In this way, the tree roots are cut off in time after entering the middle cutting layer 2, preventing them from continuing to spread and damaging the ground paving and underground facilities. At the same time, the use of solar power is not only environmentally friendly but also reduces energy costs. The automated cutting mechanism improves efficiency, reduces human intervention, and ensures effective control of the tree root system.

[0054] To increase the sliding stability of the pulley in the slide rail, grooves are provided on both the upper and lower sliding rails. The pulley 13 is connected to the motor module through the connecting member 16. The upper pulley 13 is set in the groove of the upper sliding rail, and the lower pulley is set in the groove of the lower sliding rail.

[0055] The design of two sliding grooves and coaxially connected pulleys improves the stability of the pulleys and the cutting steel strip 14, ensuring a smooth and efficient cutting process. The coaxially connected pulleys can rotate synchronously, ensuring that the movement of the cutting steel strip 14 on the track is coordinated and consistent, improving cutting efficiency and effect.

[0056] Example 3

[0057] The outer protective layer 1 includes a stainless steel box, which comprises an outer side, a lower side, a left side, and a right side. The lower side, left side, and right side are vertically and fixedly connected to the lower, left, and right sides of the outer side, respectively. The left side and right side are connected to the left and right ends of the central cut layer 2, respectively. In other words, the stainless steel box is a box body with its inner and upper sides removed.

[0058] The box, made of stainless steel, has high strength and corrosion resistance. The outer, lower, left, and right sides together form a sturdy shell, protecting the central cutting layer 2 and the inner protective layer 3 from the influence of the external environment. This provides strong physical protection for the device, preventing external pressure and corrosion from affecting the normal operation of the internal structure.

[0059] The outer protective layer 1 also includes: a pull-up drawer 5, which includes: a top panel, a left side panel, a right side panel, and a bottom frame. The bottom frame is set parallel to the top panel. The upper ends of the left side panel and the right side panel are respectively vertically fixed to the two ends of the top panel. The lower ends of the left side panel and the right side panel are respectively vertically fixed to the lower end of the bottom frame. The bottom frame is a box body with the top surface removed.

[0060] The pull-out drawer 5 is a drawer structure that can be pulled upwards, making it easy for maintenance personnel to clean up tree root residue. After a certain number of tree roots have been cut, the drawer can be pulled upwards from the stainless steel box to remove the tree roots, allowing for internal cleaning and maintenance without disassembling the entire device. Additionally, for easy pulling out, a drawer latch 6 is provided on the top panel of the pull-out drawer 5.

[0061] Example 4

[0062] The internal protective layer 3 includes: a protective steel plate 9 and a soil-proof layer.

[0063] The outer side of the protective steel plate 9 is attached to the inner side of the middle cutting layer 2, which ensures the stability of the protective steel plate 9 and can effectively protect the middle cutting layer 2, preventing the soil from collapsing into the middle cutting layer 2.

[0064] The protective steel plate 9 has multiple root-penetrating holes; these holes allow tree roots to pass through the protective steel plate 9 and enter the central cutting layer 2. In this embodiment, octagonal star-shaped perforations can be used. The main function is to protect and isolate the tree roots and the device, preventing root entanglement and interference. This protective mesh design takes into account the characteristics of root growth, effectively preventing roots from entangled with the cutting device, ensuring the long-term stability and reliability of the device. It also prevents injury to people or animals from contact.

[0065] The soil-blocking layer is attached to the inner side of the protective steel plate 9. The soil-blocking layer includes a box body, the outer side of which is attached to the protective steel plate 9. Multiple small through-holes are provided on the inner and outer sides of the box body. The box body is filled with gravel filler 11. The diameter of the small through-holes is smaller than the diameter of the gravel filler 11 to prevent gravel from leaking out. The diameter of the small through-holes can be 1-2 mm, and the diameter of the gravel filler 11 can be 20-30 mm. The gravel filler 11 inside the box body has a reverse filtration function (meaning that water in the soil can flow smoothly, while soil particles are blocked), preventing soil particles from entering but allowing water to pass through. This achieves soil retention without interfering with root access to the root control device area.

[0066] The top surface of the container is provided with a gravel filling port 8 and a cover plate 7 for sealing the gravel filling port 8. Gravel can be easily added through this filling port. The cover plate 7 on the filling port is used to seal the filling port to prevent gravel from being lost or contaminated.

[0067] Excessively long tree roots enter the central cutting layer 2 through the root-seeping holes on the protective steel plate 9 and are cut by the cutting device. The box-like structure and gravel filler 11 in the soil-proof layer work together to prevent soil particles from entering the cutting layer while allowing water to pass through, maintaining good drainage performance. The small through-hole design ensures that the gravel does not leak out and also provides a reverse filtration function. The gravel filler 11 and the small through-hole design ensure good drainage performance of the soil-proof layer, preventing water accumulation from affecting the healthy growth of the tree roots.

[0068] Example 5

[0069] The root control device also includes a tree grate 10, which is laid on the ground and located within the ring structure.

[0070] A tree grate 10 is a structure laid on the ground, typically made of metal or other sturdy materials. When laid on the ground, the tree grate 10 effectively protects the ground around tree roots, preventing ground cracking and unevenness caused by root growth. At the same time, the design of the tree grate 10 allows moisture and air to enter the soil, providing the necessary growing conditions for the tree roots.

[0071] The tree grate 10 is located inside the ring-shaped root control device, forming a complete protection system together with the root control device. The tree grate 10 not only protects the ground, but also further restricts the growth range of tree roots, ensuring that the root system does not damage the surrounding ground and infrastructure.

[0072] All components in this invention can be made of 304# stainless steel to ensure their strength and corrosion resistance.
