Description

Technical Field

[0001] This utility model relates to the field of soil stabilization grid technology, and in particular to a foldable vegetation restoration soil stabilization grid. Background Technology

[0002] Currently, in engineering activities such as mountain development, mining, and transportation infrastructure construction, soil erosion, slope instability, and vegetation degradation are becoming increasingly prominent issues, threatening the balance of the ecological environment and the safety of engineering operations. Against this backdrop, soil stabilization grids, as a commonly used protective measure that balances soil stability and vegetation restoration, have been widely applied in scenarios such as slope protection, mine reclamation, and riverbank management.

[0003] Existing soil stabilization grids are mostly rigid, monolithic structures that cannot be disassembled. Individual grids are large and heavy, resulting in low space utilization during conventional transportation and high costs, especially in mountainous areas where narrow roads prevent direct delivery by large transport equipment, necessitating multiple secondary transfers and further increasing transportation costs and manpower. During storage, these grids require significant space, increasing the site management burden for small and medium-sized construction teams with limited storage capacity. Improper stacking can also lead to grid deformation or damage, exacerbating operational pressures. Summary of the Invention

[0004] The purpose of this invention is to solve the problems mentioned above in the background technology by proposing a foldable vegetation restoration and soil stabilization grid.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a foldable vegetation restoration and soil stabilization grid, comprising a first grid frame and a second grid frame, wherein strip plates are fixedly attached to one side surface of both the first and second grid frames by hot-melt welding, and two protruding plates are fixedly installed on one side surface of the strip plates on the first grid frame, and a rotating folding device is provided between the two protruding plates, wherein the rotating folding device includes a rotating shaft rotatably connected between the two protruding plates, a rotating plate is fixedly installed on the outer wall surface of the rotating shaft, one side surface of the rotating plate is fixedly connected to the second grid frame, and a limiting plate is fixedly installed at one end of the rotating shaft.

[0006] Preferably, a U-shaped plate is fixedly installed on one side surface of the strip plate on the first grid frame, and a threaded rod is rotatably connected between the inner walls of the two sides of the U-shaped plate, with a rotating wheel fixedly installed at one end of the threaded rod.

[0007] Preferably, a groove is formed on the inner wall surface of the vertical end of the U-shaped plate, and a movable strip is threadedly connected to the surface of the threaded rod. The movable strip is slidably connected by the threaded rod and the groove.

[0008] Preferably, a rod is fixedly installed on the surface of the movable strip, and a plurality of insertion holes matching the rod are circumferentially opened on the surface of the limiting plate.

[0009] The effect achieved by the above components is that the second grid frame can be rotated and folded around the first grid frame by the cooperation of the rotating shaft and the rotating plate, which greatly reduces the overall size of the device. Compared with the existing rigid integrated grid, it is easier to stack and store after folding, which can save a lot of storage space. It can be used with small tools such as handcarts during transportation, and is especially suitable for narrow mountain roads. It does not require multiple secondary transfers, reducing manpower consumption and costs during transportation.

[0010] Preferably, both of the strip plates are provided with an adjustment device. The adjustment device includes a through groove formed on the surface of the strip plate. Both sides of the inner wall surface of the through groove are provided with elongated grooves. Two sliding seats are slidably connected between the two elongated grooves. One side surface of each of the two sliding seats is fixedly mounted with a mounting seat. Each mounting seat is provided with a mounting hole on its surface.

[0011] Preferably, a T-shaped vertical plate is fixedly installed on the top surface of both sliding seats. A vertical groove is formed on the inner wall surface of the vertical end of the T-shaped vertical plate. A movable plate is slidably connected inside the vertical groove. A limit rod is fixedly installed on the bottom surface of the movable plate. Multiple limit holes matching the limit rod are formed on the surface of both strip plates.

[0012] Preferably, a strip groove is formed on one side surface of the vertical end of the T-shaped vertical plate, and a U-shaped sliding plate is slidably connected inside the strip groove. The end of the U-shaped sliding plate away from the strip groove is fixedly connected to the moving plate.

[0013] Preferably, the horizontal end of the U-shaped sliding plate is threaded with bolts, and one side of the vertical end of the T-shaped vertical plate is uniformly provided with multiple threaded holes that match the bolts.

[0014] The effect achieved by the above components is as follows: by sliding the sliding seat along the long groove, the position of the mounting seat can be freely adjusted. When facing the site environment with uneven slopes and poor soil flatness, there is no need to cut the grid or modify the terrain. Simply slide the sliding seat to align the mounting seat with a flat ground. This solves the problems of the existing rigid grid fixing points being unadjustable and the low installation qualification rate, and adapts to the fixing needs of different terrains.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by setting a rotating folding device, the second grid frame can be rotated and folded around the first grid frame by the cooperation of the rotating shaft and the rotating plate, which greatly reduces the overall volume of the device. Compared with the existing rigid integrated grid, it is easier to stack and store after folding, which can save a lot of storage space. It can be used with small tools such as handcarts during transportation, and is especially suitable for narrow mountain roads. It does not require multiple secondary transfers, reducing manpower consumption and costs during transportation, while avoiding grid compression and deformation due to insufficient transportation space.

A limiting disk 203 is fixedly installed at one end of the rotating shaft 201. A U-shaped plate 204 is fixedly installed on one side surface of the strip plate 4 on the first grid frame 1. A threaded rod 205 is rotatably connected between the inner walls of the two sides of the U-shaped plate 204. One end of the threaded rod 205 is fixedly installed with... The device includes a rotating wheel 206, a groove 207 on the inner wall surface of the vertical end of the U-shaped plate 204, a movable strip 208 threadedly connected to the surface of the threaded rod 205, the movable strip 208 being slidably connected by the threaded rod 205 and the groove 207, a plug rod 209 fixedly installed on the surface of the movable strip 208, and multiple insertion holes 210 matching the plug rod 209 being annularly opened on the surface of the limiting plate 203. The rotating shaft 201 is made of 304 stainless steel with chrome plating for rust prevention, and the threaded rod 205 is made of 45# steel with a specification of M8×50mm, a thread precision of 6g, and chrome plating for rust prevention.

[0020] Reference Figure 2-4 As shown in this embodiment: Adjustment devices 3 are provided on the surfaces of both strip plates 4. Each adjustment device 3 includes a through groove 301 formed on the surface of the strip plate 4. Long grooves 302 are formed on the inner walls of both sides of the through groove 301. Two sliding seats 303 are slidably connected between the two long grooves 302. Mounting seats 304 are fixedly installed on one side surface of each of the two sliding seats 303. Mounting holes are formed on the surface of each mounting seat 304. T-shaped vertical plates 305 are fixedly installed on the top surfaces of both sliding seats 303. Vertical grooves 306 are formed on the inner wall surface of the vertical ends of the T-shaped vertical plates 305. A moving plate 307 is slidably connected inside the vertical grooves 306. The bottom surface of the moving plate 307... A limiting rod 308 is fixedly installed. Multiple limiting holes 309 matching the limiting rod 308 are opened on the surface of both strip plates 4. A strip groove 310 is opened on one side surface of the vertical end of the T-shaped vertical plate 305. A U-shaped sliding plate 311 is slidably connected inside the strip groove 310. The end of the U-shaped sliding plate 311 away from the strip groove 310 is fixedly connected to the moving plate 307. A bolt 312 is threadedly connected to the surface of the horizontal end of the U-shaped sliding plate 311. Multiple threaded holes 313 matching the bolt 312 are evenly opened on one side surface of the vertical end of the T-shaped vertical plate 305. A φ12mm mounting hole is opened on the surface of the mounting base 304 to accommodate φ12×300mm ground nails / anchors.

[0021] Working principle: When the transfer device needs to be carried, first rotate the wheel 206: Rotating the wheel 206 clockwise drives the threaded rod 205 to rotate on the inner wall of the U-shaped plate 204; Since the movable strip 208 is threadedly connected to the threaded rod 205 and is limited by the slide groove 207, the movable strip 208 will slide along the slide groove 207 away from the limiting plate 203. While the movable strip 208 slides, it will drive the insertion rod 209 to move synchronously until the insertion rod 209 is completely removed from the insertion hole 210 on the surface of the limiting plate 203. At this time, the limiting plate 203 loses the limitation of the insertion rod 209, and the rotating shaft 201 can rotate freely. Then, manually rotate the second grid frame 6: the second grid frame 6 rotates around the pivot 201 via the rotating plate 202, slowly rotating until it is completely in contact with the first grid frame 1. Then, rotate the rotating wheel 206 in the opposite direction: rotating the rotating wheel 206 counterclockwise causes the threaded rod 205 to rotate in the opposite direction, driving the movable strip 208 and the insertion rod 209 to reset. Insert the insertion rod 209 into the corresponding angle insertion hole 210 of the limiting plate 203, re-limiting the rotation of the limiting plate 203 and the pivot 201, ensuring the stability of the folded state. Finally, stack the folded device for storage or load it into a transport vehicle such as a trolley. Due to the significant reduction in size, it can save transport space. Suitable for storage sites and transport along narrow mountain roads, after the device is transported to its intended use location such as a slope or mining area, first rotate the wheel 206 again: rotate the wheel 206 clockwise to move the insertion rod 209 out of the insertion hole 210, releasing the limit on the limiting plate 203. Then, manually push the second grid frame 6: rotate the second grid frame 6 around the rotating shaft 201 in a direction away from the first grid frame 1 until the two grid frames are on the same horizontal plane. Next, rotate the wheel 206 counterclockwise: drive the movable strip 208 and the insertion rod 209 to reset, and the insertion rod 209 is reinserted into the insertion hole 210 of the limiting plate 203, locking the rotation. The position of axis 201 is to prevent the grid frame from rotating accidentally during use and to ensure stability in the unfolded state. After unfolding the grid, first observe the ground conditions of the application site, such as the unevenness of the slope and the flatness of the soil, to determine whether the initial position of the mounting base 304 is suitable for fixing. If the position is not appropriate, the bolt 312 needs to be loosened: use a tool to unscrew the bolt 312 from the threaded hole 313 of the T-shaped vertical plate 305. At this time, the U-shaped sliding plate 311 loses its limit in the strip groove 310. Then push the U-shaped sliding plate 311: slide the U-shaped sliding plate 311 up and down along the strip groove 310, and drive the moving plate 307 to slide synchronously in the vertical groove 306.When the movable plate 307 slides, it will cause the limiting rod 308 to disengage from the limiting hole 309 on the surface of the strip plate 4, causing the T-shaped vertical plate 305 and the sliding seat 303 to lose their limiting positions. Then, the sliding seat 303 is moved: the sliding seat 303 slides along the long grooves 302 on both sides of the through groove 301, causing the mounting seat 304 to move to a flat and easy-to-fix position on the ground. Finally, the position of the sliding seat 303 is fixed: the U-shaped sliding plate 311 is slid down, causing the movable plate 307 to drive the limiting rod 308 to insert into the corresponding limiting hole 309 on the strip plate 4. Then, the bolt 312 is screwed back into the threaded hole 313 of the T-shaped vertical plate 305 to lock the U-shaped vertical plate 305. The sliding plate 311 and the movable plate 307 ensure that the sliding seat 303 and the mounting seat 304 are fixed in position. After the mounting seat 304 is adjusted, the mounting holes on the surface of the mounting seat 304 are used to insert ground nails or anchor rods through the mounting holes and hammer them into the soil. The ground nails must penetrate the soil deeply enough to ensure a firm fixation, so that the entire grid frame is stably fixed on the slope or ground. After fixing, vegetation seeds such as bermudagrass and Amorpha fruticosa seeds are sown in the diamond-shaped units of the grid frame. The grid aperture ensures that the seeds fall into the soil without hindering the subsequent seedling emergence and root growth, achieving the dual function of "soil stabilization + vegetation restoration".
