Description

Technical Field

[0001] This invention relates to the field of soil and water conservation equipment technology, and more specifically, to a mine restoration vegetation blanket. Background Technology

[0002] In response to the ecological damage caused by soil erosion on slopes, vegetation mats have emerged as a highly efficient material for slope protection and ecological restoration. By combining plant seeds, nutrient substrates, and fiber carriers, they can quickly cover exposed surfaces, effectively inhibiting soil erosion, stabilizing slope structures, and providing a stable environment for plant growth, thus accelerating vegetation restoration. They have been widely used in various fields such as mine rock slope restoration, highway and railway slope protection, river management, and desertification control, becoming an indispensable core material in ecological restoration projects.

[0003] In related technologies, the traditional rolling operation of vegetation mats is cumbersome and laborious, and they still maintain a large volume after being stored. They occupy a lot of space during transportation, which limits the loading capacity and affects the transportation efficiency of vegetation mats. Summary of the Invention

[0004] The problem addressed by this invention is how to improve the transportation efficiency of vegetation mats.

[0005] To address the above problems, this invention provides a mine restoration vegetation blanket.

[0006] In a first aspect, the present invention provides a mine restoration vegetation blanket, comprising a blanket body, an installation component, and a folding component. The two ends of the blanket body are respectively provided with installation components, and the opposite ends of the two installation components are respectively connected by folding components. The folding components are used to fold to drive the two installation components to move closer to each other, so that the blanket body is folded and rolled up. The folding components are also used to unfold to drive the two installation components to move away from each other, so that the blanket body is unfolded and abuts against the edge of the blanket body when the blanket body is unfolded.

[0007] Optionally, the installation assembly includes a plug rod, an installation strip, and an installation base. The bottom of one side of the installation base is connected to the blanket body, and the other side of the installation base is connected to the installation strip. The two ends of the installation strip are respectively provided with first through holes, and the plug rod is used to pass through the first through holes to enter the interior of the mine slope.

[0008] Optionally, the mounting base includes a mounting base body and a positioning structure. One end of each of the two folding components is rotatably connected to both ends of the mounting base body. The two positioning structures are respectively disposed on both sides of the mounting base body. One end of each positioning structure is rotatably connected to the upper surface of the mounting base body. The positioning structure is configured such that when the folding components are unfolded, the other end of the positioning structure is connected to the corresponding folding component.

[0010] Optionally, the folding pressure bar structure includes a pressure bar body, a pressure strip, and a shaft post. A rotating groove is formed on the side of the mounting base body near the folding assembly along the axial direction of the mounting base body. The pressure strip is disposed on the side of the pressure bar body near the positioning structure. A second through hole matching the shaft post is formed at one end of the pressure bar body and the pressure strip. The shaft post passes through the second through holes of the pressure bar body and the pressure strip respectively. The two ends of the shaft post are connected to two opposite side walls at one end of the rotating groove. The middle part of the pressure strip is connected to the other end of the positioning structure.

[0011] Optionally, the vegetation mat further includes a pressure plate, an extrusion column, a first spring, and a wedge-shaped stop block. The pressure plate is disposed on the side of the pressure rod body away from the pressure strip. The side of the pressure rod body near the pressure plate has an extrusion groove adapted to the pressure plate. The first spring is spaced between the bottom of the extrusion groove and the pressure plate. The other end of the pressure strip is connected to one end of the extrusion column. A third through hole matching the extrusion column is opened in the middle of the pressure rod body. The other end of the extrusion column passes through the third through hole and abuts against the pressure plate. The wedge-shaped stop block is disposed on the inner wall of one end of the rotating groove that matches the position of the pressure strip. The wedge-shaped surface of the wedge-shaped stop block faces the pressure strip. The wedge-shaped stop block is configured such that when the folding assembly is unfolded, the pressure strip is extruded along the wedge-shaped surface of the wedge-shaped stop block toward the pressure rod body.

[0012] Optionally, the positioning structure includes a movable rod, a positioning post, and a second spring. One end of the movable rod is rotatably connected to the upper surface of the mounting base body near the shaft post. The other end of the movable rod has a fourth through hole through which the positioning post passes. The second spring is sleeved on the end of the positioning post away from the pressure bar. One end of the second spring is connected to one end of the positioning post, and the other end of the second spring is connected to the movable rod. The middle of the pressure bar has a fifth through hole that matches the positioning post. The positioning structure is configured such that when the folding assembly is unfolded, the other end of the positioning post passes through the fifth through hole and abuts against the pressure rod body.

[0013] Optionally, the mounting base body has a positioning blind hole on one side of the movable rod that matches the positioning post, and the positioning structure is configured such that when the folding assembly is folded, the other end of the positioning post is disposed in the positioning blind hole.

[0014] Optionally, a limiting sleeve is provided at the middle of the upper surface of the mounting strip, and the limiting sleeve has a sixth through hole that matches the plug rod along the axial direction of the mounting strip. The sixth through hole is used to place the plug rod.

[0015] Optionally, the vegetation blanket further includes a binding strap, a female opening, and a female buckle. One end of the binding strap is connected to the middle of the upper surface of the mounting base body at one end of the blanket body. The other end of the binding strap is provided with the female opening. The middle of the upper surface of the mounting base body at the other end of the blanket body is provided with a female buckle that matches the female opening. The binding strap is configured such that when the folding assembly is folded, the female opening passes around the blanket body and connects to the female buckle.

[0016] The beneficial effects of the mine restoration vegetation blanket of the present invention are as follows: In the folded state, the blanket can be gathered into a compact state through the folding component. Compared with the traditional flat-lay vegetation blanket, the number of vegetation blankets that can be loaded in a unit transportation space is greatly increased, effectively reducing the transportation frequency and unit transportation cost. At the same time, the integrated connection design of the installation component and the folding component avoids the cumbersome loading and unloading problems caused by the transportation of components in a scattered manner. The overall structure of the folded vegetation blanket is neat and tidy, which is easy to stack, handle and count, reducing the manpower consumption and component damage during transportation. Moreover, the gathered blanket does not require additional large packaging protection, further simplifying the transportation process and shortening the transportation preparation time. It is especially suitable for the large-scale and long-distance material transportation needs in mine restoration projects. Attached Figure Description

[0022] Combination Figure 1As shown in the figure, an embodiment of the present invention provides a mine restoration vegetation blanket, including a blanket body 1, an installation component 2, and a folding component 3. The installation components 2 are respectively provided at both ends of the blanket body 1, and the opposite ends of the two installation components 2 are respectively connected by the folding component 3. The folding component 3 is used to fold to drive the two installation components 2 to move closer to each other, so that the blanket body 1 is folded and rolled up. The folding component 3 is also used to unfold to drive the two installation components 2 to move away from each other, so that the blanket body 1 is unfolded, and abuts against the edge of the blanket body 1 when the blanket body 1 is unfolded.

[0023] Specifically, the two mounting components 2 can be located on the left and right sides of the blanket body 1 respectively, and the two folding components 3 can be located on the upper and lower sides of the blanket body 1 respectively, so as to connect the upper and lower ends of the mounting components 2. When the folding component 3 is folded, it serves as the core connecting structure linking the two mounting components 2 at both ends of the blanket 1. It can bring the two mounting components 2 closer together, causing the blanket 1 to fold and retract. After folding, it can be rolled up, preventing the blanket 1 from taking up too much space or its edges from being worn when it is not in use. At the same time, the mounting components 2 can serve as support bases during the folding process, preventing the blanket 1 from scattering and shifting after folding. When the folding component 3 is unfolded, the abutment design between the folding component 3 and the edge of the blanket 1 can quickly position the unfolded shape of the blanket 1, making the blanket 1 form a flat covering surface. Meanwhile, the mounting components 2 can be fixed to the mine surface by anchoring, snap-fitting, etc. The tight fit between the folding component 3 and the edge of the blanket 1 can further enhance the laying stability of the blanket 1, preventing the blanket 1 from lifting or shifting due to external forces such as wind and water flow, and providing a stable base environment for vegetation growth in mine restoration.

[0024] In this embodiment, when folded, the blanket 1 can be folded into a compact state by the folding component 3. Compared with traditional flat-laid vegetation blankets, the number of vegetation blankets that can be loaded in a unit transportation space is greatly increased, effectively reducing the transportation frequency and unit transportation cost. At the same time, the integrated connection design of the installation component 2 and the folding component 3 avoids the cumbersome loading and unloading problems caused by the transportation of components separately. The overall structure of the folded vegetation blanket is neat and easy to stack, handle and count, reducing the manpower consumption and component damage during transportation. Moreover, the folded blanket 1 does not require additional large packaging protection, further simplifying the transportation process and shortening the transportation preparation time. It is especially suitable for the large-scale, long-distance material transportation needs in mine restoration projects.

[0025] Optionally, combined Figure 1As shown, the installation assembly 2 includes a plug rod 5, an installation strip 21, and an installation base 22. The bottom of one side of the installation base 22 is connected to the blanket body 1, and the other side of the installation base 22 is connected to the installation strip 21. The two ends of the installation strip 21 are respectively provided with first through holes 23. The plug rod 5 is used to pass through the first through holes 23 to enter the interior of the mine slope.

[0026] In this optional embodiment, the bottom of one side of the mounting base 22 is securely connected to the blanket body 1, ensuring that the mounting base 22 and the blanket body 1 form an inseparable whole, preventing the mounting base 22 from detaching from the blanket body 1 during installation. The other side of the mounting base 22 is connected to the mounting strip 21, providing a stable support point for the installation of the plug-in rod 5. The first through holes 23 at both ends of the mounting strip 21 are precisely matched to the size specifications of the plug-in rod 5. During installation, one end of the plug-in rod 5 can be inserted directly into the mine slope through the through hole. The other end of the plug-in rod 5 is provided with an end cap, the size of which is larger than the first through hole 23. When the plug-in rod 5 is inserted into the mine slope, the end cap fixes and compresses the mounting strip 21. Through the interlocking action between the plug-in rod 5 and the slope soil, combined with the conductive support of the mounting base 22 and the mounting strip 21, the blanket body 1 can be firmly fixed to the mine surface, effectively resisting external impacts, ensuring the stability of the vegetation blanket after laying, and laying a solid foundation for vegetation growth.

[0027] Optionally, combined Figure 1 and Figure 2 As shown, the mounting base 22 includes a mounting base body 221 and a positioning structure 222. One end of each of the two folding components 3 is rotatably connected to both ends of the mounting base body 221. The two positioning structures 222 are respectively disposed on both sides of the mounting base body 221. One end of each positioning structure 222 is rotatably connected to the upper surface of the mounting base body 221. The positioning structure 222 is configured such that when the folding component 3 is unfolded, the other end of the positioning structure 222 is connected to the corresponding folding component 3.

[0028] In this optional embodiment, one end of each of the two folding components 3 is rotatably connected to both ends of the mounting base body 221. This connection method provides a flexible basis for the folding and unfolding of the folding components 3, ensuring smooth and seamless switching between component states. Two positioning structures 222 are correspondingly arranged on both sides of the mounting base body 221, with one end rotatably connected to the upper surface of the mounting base body 221. The angle can be freely adjusted. When the folding component 3 is unfolded to the working state of abutting against the edge of the blanket 1, the other end of the positioning structure 222 can be connected to the corresponding folding component 3. The position of the unfolded folding component 3 is locked through limiting and fixing, preventing it from rotating or shifting due to external forces during use. This ensures the flatness and stability of the overall vegetation blanket laying, creating reliable conditions for subsequent vegetation cultivation.

[0029] Optionally, combined Figure 1 As shown, the folding assembly 3 includes a folding pressure rod structure 31 and a connecting piece 32. The two folding pressure rod structures 31 are rotatably connected through the connecting piece 32. The end of the folding pressure rod structure 31 away from the connecting piece 32 is rotatably connected to the corresponding end of the mounting base body 221.

[0030] In this optional embodiment, the two folding pressure bar structures 31 are rotatably connected by a connecting piece 32. The connecting piece 32 serves as a rotational pivot, providing a smooth fulcrum for both structures, allowing the folding pressure bar structure 31 to rotate freely around the connecting piece 32, thereby enabling the entire folding assembly 3 to be folded up or unfolded flat. Each folding pressure bar structure 31 has its end away from the connecting piece 32 rotatably connected to one end of the corresponding mounting base body 221. This dual rotatable connection design (folding pressure bar structure 31 and connecting piece 32, folding pressure bar structure 31 and mounting base body 221) ensures a stable connection between the folding assembly 3 and the mounting base 22, while also giving the assembly ample freedom of movement. When folding, the two folding pressure bar structures 31 can be brought closer together by rotating the connecting piece 32, causing the blanket 1 to fold into a compact state. When unfolding, they can be extended to the position where they abut against the edge of the blanket 1 by rotating, and then fixed in place with the positioning structure 222 on the mounting base 22. This not only realizes the convenient storage and transportation of the vegetation blanket, but also provides edge support for the blanket 1 after laying, enhancing the stability of the overall structure.

[0031] Optionally, combined Figure 1 and Figure 4 As shown, the folding pressure bar structure 31 includes a pressure bar body 311, a pressure strip 312, and a shaft post 313. The mounting base body 221 has a rotating groove along the axial direction of the mounting base body 221 on the side near the folding assembly 3. The pressure strip 312 is disposed on the side of the pressure bar body 311 near the positioning structure 222. One end of the pressure bar body 311 and the pressure strip 312 are respectively provided with a second through hole 24 that matches the shaft post 313. The shaft post 313 passes through the second through hole 24 of the pressure bar body 311 and the pressure strip 312 respectively. The two ends of the shaft post 313 are connected to the two opposite side walls of one end of the rotating groove. The middle part of the pressure strip 312 is connected to the other end of the positioning structure 222.

[0032] In this optional embodiment, the mounting base body 221 has a rotating groove along its axial direction on the side near the folding assembly 3, providing a stable assembly space for the installation of the shaft post 313. The pressure strip 312 is disposed on the side of the pressure rod body 311 near the positioning structure 222, and the two form a functionally complementary component. One end of both the pressure rod body 311 and the pressure strip 312 has a second through hole 24 that matches the shaft post 313. After the shaft post 313 passes through the two second through holes 24 in sequence, its two ends are fixedly connected to the opposite side walls of the rotating groove at the corresponding ends, so that the pressure rod body 311 and the pressure strip 312 are connected. The 12 components are hinged to the rotating groove via the shaft column 313, which not only ensures the stability of the connection but also provides a flexible fulcrum for the rotation of the folding pressure bar structure 31, ensuring that it can smoothly achieve folding or unfolding. The middle part of the pressure bar 312 is connected to the other end of the positioning structure 222. When the folding component 3 is unfolded into place, the positioning structure 222 completes the limit locking of the folding pressure bar structure 31 through the connection with the pressure bar 312, preventing it from rotating accidentally during use. This ensures the abutment support effect of the entire folding component 3 on the edge of the blanket 1 and strengthens the structural stability after the vegetation blanket is laid.

[0033] Optionally, combined Figures 3 to 5 As shown, the vegetation mat also includes a pressing plate 314, an extrusion column 315, a first spring 316, and a wedge-shaped stop block 6. The pressing plate 314 is disposed on the side of the pressure rod body 311 away from the pressure receiving strip 312. The side of the pressure rod body 311 near the pressing plate 314 has an extrusion groove adapted to the pressing plate 314. The first spring 316 is spaced between the bottom of the extrusion groove and the pressing plate 314. The other end of the pressure receiving strip 312 is connected to one end of the extrusion column 315. The pressure rod body 314... A third through hole 25 matching the extrusion column 315 is provided in the middle of 11. The other end of the extrusion column 315 passes through the third through hole 25 and abuts against the pressure plate 314. The wedge-shaped block 6 is disposed on the inner wall of one end of the rotating groove that matches the position of the pressure strip 312. The wedge-shaped surface of the wedge-shaped block 6 faces the pressure strip 312. The wedge-shaped block 6 is configured such that when the folding assembly 3 is unfolded, the pressure strip 312 is pressed along the wedge-shaped surface of the wedge-shaped block 6 toward the pressure rod body 311.

[0034] In this optional embodiment, the pressure plate 314 is disposed on the side of the pressure rod body 311 away from the pressure strip 312, that is, the pressure plate 314 is disposed between the pressure rod body 311 and the blanket 1. The pressure rod body 311 has a matching extrusion groove at the position corresponding to the pressure plate 314. The first spring 316 is spaced apart between the bottom of the extrusion groove and the pressure plate 314 to provide elastic support and reset capability for the pressure plate 314. When the pressure rod body 311 is unfolded, the first spring 316 extrudes the pressure plate 314, so that the edge of the blanket 1 below the pressure plate 314 is tightly attached to the surface of the mine slope, avoiding the situation of the blanket 1 curling up during installation. The other end of the pressure bar 312, away from the shaft post 313, is fixedly connected to one end of the extrusion post 315. A third through hole 25, precisely matching the size of the extrusion post 315, is provided in the middle of the pressure rod body 311. The other end of the extrusion post 315 passes through this through hole and tightly abuts against the pressure plate 314, forming a force transmission path. The wedge-shaped block 6 is fixedly installed on the inner wall of one end of the rotating groove, corresponding to the position of the pressure bar 312, with its wedge-shaped surface facing the pressure bar 312. When the folding assembly 3 is unfolded, the pressure bar 312 will contact the wedge-shaped surface of the wedge-shaped block 6 during the rotation of the folding pressure rod structure 31. As the unfolding action continues... The wedge-shaped surface exerts a guiding and squeezing effect on the pressure strip 312, causing the pressure strip 312 to move towards the pressure bar body 311. This, in turn, drives the extrusion column 315 to apply pressure towards the pressure plate 314, causing the pressure plate 314 to squeeze the edge of the blanket 1, making it tightly adhere to the surface of the mine slope. At the same time, the generated reaction force will act in the opposite direction on the pressure strip 312 through the pressure plate 314 and the extrusion column 315, making the pressure strip 312 tightly adhere to the wedge-shaped block 6, achieving self-locking positioning. This prevents the folding component 3 from retracting or loosening after unfolding, thus firmly locking the unfolded shape of the vegetation blanket and ensuring the structural stability after laying.

[0035] Optionally, such as Figure 1 and Figure 3 As shown, the positioning structure 222 includes a movable rod 2221, a positioning post 2222, and a second spring 2223. One end of the movable rod 2221 is rotatably connected to the upper surface of the mounting base body 221 near the shaft post 313. The other end of the movable rod 2221 has a fourth through hole 26 through which the positioning post 2222 passes. The second spring 2223 is sleeved on the end of the positioning post 2222 away from the pressure bar 312. One end of the second spring 2223 is connected to one end of the positioning post 2222, and the other end of the second spring 2223 is connected to the movable rod 2221. The middle part of the pressure bar 312 has a fifth through hole that matches the positioning post 2222. The positioning structure 222 is configured such that when the folding assembly 3 is unfolded, the other end of the positioning post 2222 passes through the fifth through hole and abuts against the pressure rod body 311.

[0036] In this optional embodiment, one end of the movable rod 2221 is rotatably connected to the side of the upper surface of the mounting base body 221 near the shaft post 313. The rotatable connection point is offset from the shaft post 313, and the movable rod 2221 can rotate freely around the connection point, which facilitates the adjustment of the angle according to the unfolded state of the folding assembly 3. The other end of the movable rod 2221 is provided with a fourth through hole 26. The positioning post 2222 passes through the through hole to achieve a sliding fit with the movable rod 2221. The second spring 2223 is sleeved on the end of the positioning post 2222 away from the pressure bar 312. One end of the spring is fixedly connected to the end of the positioning post 2222, and the other end is connected to the movable rod 2221. The elastic tension of the spring provides a preload force to the positioning post 2222 in the direction of the pressure bar 312. The middle of the pressure strip 312 is provided with a fifth through hole that precisely matches the size of the positioning post 2222. When the folding assembly 3 is unfolded into place, rotating the movable rod 2221 can align the positioning post 2222 with the fifth through hole. Since the other end of the second spring 2223 is fixedly connected to the movable rod 2221, under the contraction of the second spring 2223, the other end of the positioning post 2222 passes through the fifth through hole and abuts against the pressure rod body 311. The movement of the pressure strip 312 is restricted by the insertion and cooperation between the positioning post 2222 and the fifth through hole, and the position of the pressure rod body 311 is locked. Through the limiting cooperation and the continuous contraction of the second spring 2223, the folding assembly 3 is effectively prevented from loosening or folding back due to vibration or external impact during use, ensuring the stability of the vegetation blanket after unfolding and providing reliable structural support for vegetation growth. When the folding assembly 3 is folded, one end of the positioning post 2222 needs to be pulled to overcome the contraction force of the second spring 2223, thereby stretching the second spring 2223, which in turn causes the other end of the positioning post 2222 to be pulled out of the fifth through hole, and then contact the movable rod 2221 to position the folding assembly 3.

[0037] It should be noted that the misalignment of the rotation connection point between one end of the movable rod 2221 and the upper surface of the mounting base body 221 and the shaft post 313 achieves a reliable positioning effect. When the folding assembly 3 is unfolded, the folding pressure rod structure 31 rotates around the shaft post 313, while the movable rod 2221 of the positioning structure 222 rotates around its own rotation connection point. The rotation centers of the two (the connection point between the shaft post 313 and the movable rod 2221) are not collinear, forming a misaligned "double rotation center". This misalignment results in an angular difference between the rotation trajectory of the movable rod 2221 and the rotation trajectory of the folding pressure rod structure 31 (and the pressure strip 312). When the folding assembly 3 is unfolded to the correct position, the movable rod 2221 can rotate itself to make the positioning post 2222 precisely align with the fifth through hole, avoiding trajectory overlap or interference caused by coaxial rotation, and ensuring the accuracy of insertion positioning. On the other hand, when the positioning post 2222 is inserted... After the fifth through hole, if the folding assembly 3 is subjected to external force and attempts to fold back (rotate in the opposite direction around the shaft 313), the misalignment will cause the constraint force of the movable rod 2221 on the positioning post 2222 to form an angle with the rotation direction of the folding pressure rod structure 31, generating a "lever" resistance. The rotation tendency of the shaft 313 will be limited by the cooperation between the positioning post 2222 and the fifth through hole. Due to the misalignment of the rotation center, the support point (mount body 221) and the force point (positioning post 2222) of the movable rod 2221 form a lever arm. With the preload of the second spring 2223, it can firmly "lock" the pressure strip 312, preventing the positioning post 2222 from disengaging from the through hole, thereby achieving stable positioning and locking and preventing the folding assembly 3 from accidentally loosening. Optionally, combined Figure 1 and Figure 3 As shown, the mounting base body 221 has a positioning blind hole 223 on one side of the movable rod 2221 that matches the positioning post 2222. The positioning structure 222 is configured such that when the folding assembly 3 is folded, the other end of the positioning post 2222 is placed in the positioning blind hole 223.

[0038] In this optional embodiment, the mounting base body 221 has a positioning blind hole 223 on one side of the movable rod 2221 that precisely matches the size of the positioning post 2222. The positioning blind hole 223 can be symmetrically arranged on both sides of the rotation connection point between the movable rod 2221 and the mounting base body 221. The positioning blind hole 223 and the positioning structure 222 work together to realize the storage of the positioning structure 222. When the vegetation blanket needs to be folded and stored, rotate the folding pressure rod structure 31 to bring it closer to the mounting base body 221. At the same time, rotate the movable rod 2221 of the positioning structure 222 to adjust its angle so that the positioning post 2222 is aligned with the positioning blind hole 223. After the other end of the positioning post 2222 is inserted into the positioning blind hole 223, under the pre-tightening force (contraction force) of the second spring 2223, the other end of the positioning post 2222 will abut against the bottom of the positioning blind hole 223. This prevents the vegetation blanket from being accidentally unfolded due to bumps or external force during transportation and storage, ensuring that the vegetation blanket maintains a compact and neat shape after folding. This facilitates handling and storage, protects the components from collision damage, and provides a stable structural foundation for subsequent unfolding and laying.

[0039] Optionally, combined Figure 1 and Figure 2 As shown, a limiting sleeve 4 is provided in the middle of the upper surface of the mounting strip 21. The limiting sleeve 4 has a sixth through hole that matches the plug rod 5 along the axial direction of the mounting strip 21. The sixth through hole is used to place the plug rod 5.

[0040] In this optional embodiment, a limiting sleeve 4 is fixedly provided at the center of the upper surface of the mounting strip 21. The limiting sleeve 4 has a sixth through hole along the axial direction of the mounting strip 21, which precisely matches the size of the plug-in rod 5. The position of the sixth through hole corresponds to the first through holes 23 at both ends of the mounting strip 21. Its function is to provide dedicated storage and positioning space for the plug-in rod 5. When the vegetation blanket is being transported or not laid, the plug-in rod 5 can be placed directly in the sixth through hole to prevent the plug-in rod 5 from being lost or damaged due to scattered storage. At the same time, the limiting sleeve 4 can form a radial constraint on the plug-in rod 5 to prevent the plug-in rod 5 from being damaged by collision due to bumps during transportation. When laying the vegetation mat, simply remove the plug rod 5 from the sixth through hole and quickly align it with the first through holes 23 at both ends of the installation strip 21 to insert it into the mine slope. There is no need to find or adjust the position of the plug rod 5. This not only improves the convenience and efficiency of the installation operation, but also indirectly strengthens the verticality and stability of the plug rod 5 after installation through the matching cooperation between the limiting sleeve 4 and the plug rod 5, preventing it from being tilted under force, and further ensuring the fixing effect of the installation component 2 on the mat body 1.

[0041] Optionally, combined Figure 1 and Figure 2As shown, the vegetation blanket also includes a binding strap 7, a male opening 8, and a female buckle 9. One end of the binding strap 7 is connected to the middle of the upper surface of the mounting base body 221 at one end of the blanket body 1. The other end of the binding strap 7 is provided with the male opening 8. The middle of the upper surface of the mounting base body 221 at the other end of the blanket body 1 is provided with a female buckle 9 that matches the male opening 8. The binding strap 7 is configured such that when the folding assembly 3 is folded, the male opening 8 passes around the folded and rolled-up blanket body 1 and connects to the female buckle 9.

[0042] In this optional embodiment, the vegetation blanket forms a secondary reinforcement structure after folding through the binding strap 7, the male opening 8, and the female buckle 9, further ensuring the stability of the stored state. One end of the binding strap 7 is fixedly connected to the middle of the upper surface of the mounting base body 221 at one end of the blanket body 1, and the other end is equipped with the male opening 8. The middle of the upper surface of the mounting base body 221 at the other end of the blanket body 1 is correspondingly provided with a female buckle 9 that precisely matches the size and structure of the male opening 8. After the folding assembly 3 completes the initial folding and locking through the positioning structure 222 and the positioning blind hole 223, the binding strap 7 can pass around the folded blanket body 1 from one side (that is, as the two mounting base bodies 221 at both ends of the blanket body approach each other, the blanket body 1 is folded in half, and then rolled up after folding). The entire structure is folded up, allowing the male end 8 to precisely engage with the female buckle 9 on the mounting base 22 at the other end of the blanket body 1. The binding force of the strap 7, combined with the snap-fit ​​of the male end 8 and the female buckle 9, forms a locking effect, preventing the vegetation blanket from coming loose due to severe bumps or external pulling during transportation, handling, or storage. At the same time, it allows the folded blanket body 1 to maintain a more compact and regular shape, reducing space occupation and facilitating stacking. It also protects the blanket body 1 and its components from collision and wear, further improving the portability and transportation safety of the vegetation blanket.

[0043] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
