[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figures 1-8 This invention provides a technical solution: a combined adjustable vegetation fixing device for mine ecological restoration, such as... Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 8As shown, the structure includes a vegetation fixing structure 1 for mine ecological restoration. The vegetation fixing structure 1 includes a first clamp plate 11, a second clamp plate 12 rotatably connected to the first clamp plate 11, and the first clamp plate 11 fixed to the second clamp plate 12 via a fixing assembly 13. Vegetation clamping assemblies 14 for mine ecological restoration are installed on both the first clamp plate 11 and the second clamp plate 12. The fixing assembly 13 includes a first fixing plate 131, and a first screw 133 rotatably connects the first fixing plates 131 via a rotating rod 132. The screw 133 passes through the threaded limiting plate 134. The right side of the first screw 133 is threadedly connected to a spiral fixing block 135. The vegetation clamping component 14 for mine ecological restoration includes a U-shaped plate 141. The U-shaped plate 141, the first clamp plate 11, and the second clamp plate 12 are all connected to a second screw 142. The top of the second screw 142 is equipped with an anti-slip handle 143. The other end of the second screw 142 is rotatably connected to the rotating block 145. The rotating block 145 is equipped with an arc-shaped clamping plate 146. The second screw 142 is connected to a spring 144. The first screw 133 has multiple limiting holes, which are evenly distributed on the first screw 133. The threaded limiting plate 134 has limiting holes to facilitate auxiliary fixing through the limiting fuse later. Specifically, the vegetation clamping components 14 for mine ecological restoration are provided in four sets, and the four sets of vegetation clamping components 14 for mine ecological restoration are symmetrically arranged about the central axis of the space enclosed by the first clamp plate 11 and the second clamp plate 12. Furthermore, anti-slip pads are installed on the arc-shaped clamping plate 146 to protect the vegetation surface; In the above scheme, the first clamp plate 11 and the second clamp plate 12 are attached to the vegetation. The first screw 133 between the first fixing plates 131 is rotated. With the assistance of the rotating rod 132, the first screw 133 rotates and is embedded in the threaded limiting plate 134. The spiral fixing block 135 is rotated, and the spiral fixing block 135 rotates on the first screw 133, thereby fixing the first clamp plate 11 and the second clamp plate 12. The fuse is passed through the threaded limiting plate 134 and the first screw. The limiting hole on 133 is used to fix the threaded limiting plate 134 and the first screw 133 with a fuse, thus playing a double limiting role. Rotating the anti-slip handle 143 on the U-shaped plate 141 causes the second screw 142 to rotate. The rotation of the second screw 142 causes the spring 144 to be compressed, and the arc-shaped clamping plate 146 is moved through the rotating block 145, thereby causing the arc-shaped clamping plate 146 to limit and fix branches of different sizes. like Figure 1 , Figure 2 , Figure 3 , and 4 and Figure 6As shown, the vegetation fixing structure 1 for mine ecological restoration is equipped with a support structure 2, a spraying structure 3, and a leveling structure 4. The support structure 2 is located below the vegetation fixing structure 1. The support structure 2 includes a height adjustment component 21, with a mounting base 22 installed below it. A limit component 23 passes through the mounting base 22, and a second connecting ring 24 is suspended from the limit component 23. A first ring rotating component 25 is fixed to the second connecting ring 24. An auxiliary connecting component 26 is suspended from the limit component 23, and a fifth connecting ring 27 is suspended from the auxiliary connecting component 26. A second ring rotating component 28 is installed on the fifth connecting ring 27, and a second threaded ground nail 29 is suspended from the second ring rotating component 28 for further fixation. The degree adjustment component 21 includes a second fixed plate 211, a sliding rod 212 rotatably connected to the second fixed plate 211, a threaded hole 213 on the sliding rod 212, the sliding rod 212 slidably connected in the support rod 214 and fixed by bolts 215; the limiting component 23 includes a first threaded ground nail 231, a hammer block 232 installed on the upper side of the first threaded ground nail 231, and first connecting rings 233 installed on both sides of the first threaded ground nail 231; the first ring rotation component 25 includes a connecting rod 251, a rotating ring 252 rotatably connected to the connecting rod 251; the auxiliary connection component 26 includes a third connecting ring 261, a fourth connecting ring 262 suspended on the third connecting ring 261, and a connecting rope 263 fixed on the fourth connecting ring 262. Among them, the support structure 2 is provided in four sets, and the four sets of support structures 2 are equally distributed on the first clamp plate 11 and the second clamp plate 12; Specifically, the sliding rod 212 has multiple threaded holes 213, which are evenly distributed on the sliding rod 212. The second fixing plate 211 has threaded holes 213, and the mounting base 22 has through-holes. Furthermore, the second ring rotating assembly 28 and the first ring rotating assembly 25 have the same structure; In the above scheme, rotating the sliding rod 212 between the second fixing plates 211 and pulling the sliding rod 212 moves it out from the support rod 214 to the desired position. Bolts 215 are then inserted into the threaded holes 213 on the support rod 214 and the sliding rod 212, thereby installing and fixing the support rod 214 and the sliding rod 212, and adjusting the height of the vegetation fixing structure 1 for mine ecological restoration. The first threaded ground nail 231 is inserted through the mounting base 22, and the hammer block 232 is struck with a hammer or other tool to fix the first threaded ground nail 231 to the mine to be restored. Other connecting ropes 263 are then... Installed on the rotating ring 252, the rotating ring 252 rotates on the connecting rod 251 to avoid knotting. Multiple other connecting ropes 263 are cross-adjusted to increase the stability of the entire device. The third connecting ring 261 is suspended on the first connecting ring 233. The connecting rope 263 on the fourth connecting ring 262 is pulled. The second threaded ground nail 29 is inserted into the repaired mine through the connecting rope 263, the fifth connecting ring 27, and the second ring rotating assembly 28. Similarly, the upper side of the second threaded ground nail 29 is struck with a hammer or other tools to install the second threaded ground nail 29 in the repaired mine, thereby improving the stability of the entire fixing device.

[0026] like Figure 1 , Figure 2 and Figure 7 As shown, a sprinkler structure 3 is installed on the upper side of the vegetation fixing structure 1 for mine ecological restoration and is used to spray water on the vegetation. The sprinkler structure 3 includes a water inlet pipe 31. The water inlet pipe 31 is detached and installed with a water delivery pipe 33 through a threaded connector 32. The water delivery pipe 33 is connected to a sprinkler assembly 34. The sprinkler assembly 34 is installed on a first arc-shaped connecting plate 35. The sprinkler assembly 34 includes a water supply pipe 341. The water supply pipe 341 is connected to a sprinkler head 342. A first support block 343 is installed on the sprinkler head 342. A first sealing plate 344 is rotatably connected between the first support blocks 343. Spray structure 3 is installed on both the first clamp plate 11 and the second clamp plate 12; Specifically, multiple spray nozzles 342 are connected to the water supply pipe 341, and the multiple spray nozzles 342 are distributed at equal intervals on the water supply pipe 341; Furthermore, a filter and a pressure pump are installed on the water supply pipe 33 to filter the liquid entering the spray nozzle 342 and prevent the spray nozzle 342 from clogging. In the preferred embodiment, the external control device starts the filter and the pressurizing pump. With the assistance of the filter, impurities are filtered. The filter is a prior art technology. The filtered liquid is pressurized by the pressurizing pump and enters the water supply pipe 341 on the first arc-shaped connecting plate 35 through the water inlet pipe 31, the threaded connector 32 and the water delivery pipe 33. Finally, it enters the spray nozzle 342. The pressurized water opens the first sealing plate 344 between the first support blocks 343, so that the spray water sprays the vegetation. No manual operation is required, which improves the survival rate of the vegetation.

[0027] like Figure 1 , Figure 2 and Figure 7 As shown, a leveling structure 4 is installed on the spray structure 3 to facilitate the leveling of the entire fixing device in the later stage. The leveling structure 4 includes a second arc-shaped connecting plate 41, on which an electronic level body 42 is embedded. A sealing protection component 43 is provided on the upper side of the electronic level body 42 and is rotatably connected to the second arc-shaped connecting plate 41. The sealing protection component 43 includes a protrusion 431, and a second sealing plate 432 is rotatably connected between the protrusions 431. The second sealing plate 432 is embedded in a sealing groove 433. The sealing groove 433 is opened on the second arc-shaped connecting plate 41, and the electronic level body 42 is embedded in the sealing groove 433. The second sealing plate 432 is provided in two sets, and the two sets of second sealing plates 432 are rotatably connected. A sealing ring is installed on the lower side of the second sealing plate 432, thereby sealing the sealing groove 433. In the preferred embodiment, the electronic level body 42 on the second arc-shaped connecting plate 41 is used for precise leveling. The leveled surface of the device is more conducive to the attachment of plant seeds and the development of roots, avoiding displacement or partial suspension of the device due to uneven slope, and enhancing the physical protection performance of the surface soil of the slope. The data detected by the electronic level body 42 is transmitted to the processor for processing, and the processed data is transmitted to the control device. With the assistance of the control device, an alarm is triggered to the background, so that if the vegetation fixing device tilts too much in the later stage, the staff can promptly grasp the data and make adjustments when the situation is serious, so as to avoid collapse and unnecessary losses. The second sealing plate 432 on the protrusion 431 is opened to observe the electronic level body 42 in the sealing groove 433, which facilitates the stability of the vegetation fixing device during installation.

[0028] Working principle: When using this combined adjustable vegetation fixing device for mine ecological restoration, connect the external power supply, fix vegetation of different sizes through the setting of vegetation fixing structure 1 for mine ecological restoration, adjust and fix the coverage of vegetation fixing structure 1 through the setting of support structure 2, automatically spray the vegetation through the setting of spray structure 3, and level the entire device through the setting of leveling structure 4.
