[0015] See Figure 1-3 A modular forestry and grassland planting structure for ecological restoration of abandoned mine slopes includes a shell 1, an ecological unit 2 inside the shell 1, and limiting rods 12 on both sides of the shell 1. The ecological unit 2 includes four fixing members 21. A filter screen 22, a permeable layer 23, a porous plate 24, and a plant layer 25 are fixed on the four fixing members 21 from bottom to top. Each fixing member 21 is provided with a connecting plate 26. Two connecting plates 26 on the same side as the limiting rods 12 form a group. Each group of connecting plates 26 is rotatably connected to a U-shaped connecting plate 27. The U-shaped connecting plate 27 cooperates with the limiting rods 12 to achieve locking.

[0016] During assembly, the operator first fixes the filter screen 22 to four fixing parts 21, then places the permeable layer 23 on the filter screen 22, then places a perforated plate 24 on the permeable layer 23, and then places a plant layer 25 on the perforated plate 24. Next, the connecting plate 26 and the U-shaped connecting plate 27 are installed on the fixing parts 21, completing the assembly of the ecological unit 2. The ecological unit 2 is then placed inside the housing 1, and the U-shaped connecting plate 27 is restricted by the limiting rod 12 on the housing 1, thus connecting the housing 1 and the ecological unit 2 into a whole. The operator can then transport the device. During installation, the operator places the device in the designated position, then controls the limiting rod 12 to release the restriction on the U-shaped connecting plate 27, allowing the operator to separate the ecological unit 2 from the housing 1 for quick disassembly and installation, improving installation efficiency. Through the interaction of the plant layer 25 and the permeable layer 23 in the ecological unit 2, the stability of the slope planting is ensured, improving the plant growth and survival rate, thereby achieving slope restoration.

[0017] In some embodiments, a baffle 121 is fixedly connected to the limiting rod 12, and a through groove 28 is provided on the U-shaped connecting plate 27. The diameter of the through groove 28 is smaller than the length of the baffle 121. When the operator removes the ecological unit 2, the limiting rod 12 is rotated so that the baffle 121 of the limiting rod 12 is in a horizontal state, allowing the limiting rod 12 to pass through the through groove 28, making it easier for the operator to remove the ecological unit 2 from the housing 1 and speeding up the laying rate.

[0018] In some embodiments, a lifting strap 11 is provided on the side of the housing 1. The lifting strap 11 enables operators to easily move multiple devices simultaneously during installation, thereby improving installation efficiency.

[0019] In some embodiments, the fixing member 21 includes a fixing rod 211, on which a first pressure rod 212, a second pressure rod 213, and a nut 214 are arranged sequentially from bottom to top. The filter screen 22 is fixed by the first pressure rod 212 and the fixing rod 211, and the permeable layer 23, the porous plate 24, and the plant layer 25 are fixed by the second pressure rod 213 and the first pressure rod 212. The nut 214 is used to lock the filter screen 22, ensuring the stability of the ecological unit 2. The assembly is also very convenient and quick. In some embodiments, the bottom of the fixing rod 211 is tapered, and the rod is threaded. The tapered bottom of the fixing rod 211 facilitates the insertion of the ecological unit 2 into the soil for fixation, and the thread of the rod can be screwed into the first pressure rod 212, the second pressure rod 213 and the nut 214, thereby ensuring the stability of the permeable layer 23 and the plant layer 25 and preventing the ecological unit 2 from loosening during transportation.

[0020] In some embodiments, the permeable layer 23 is made of a low-cost material. The permeable layer 23 is a combination of straw, coconut fiber, wood chips, or biodegradable materials with fabric, but is not limited thereto.

[0021] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
