Description

Technical Field

[0001] This application relates to the field of ecological restoration technology, and in particular to a mine ecological restoration device. Background Technology

[0002] Currently, mines provide abundant mineral resources for industrial production, but mining also causes enormous damage to the ecological environment. As people's awareness of ecological environmental protection increases, mines have begun to carry out ecological restoration of mined areas. Ecological restoration is a comprehensive method of restoring polluted environments under the guidance of ecological principles, based on biological restoration, and combined with various physical restoration, chemical restoration, and engineering technology measures. Through optimized combination, it achieves the best results and the lowest cost. Mining areas often suffer ecological damage and need restoration. At present, the ecological restoration of abandoned mines is mainly carried out by combining the planting of woody and herbaceous plants.

[0003] The existing technical solutions mentioned above have the following drawbacks: In the early stages of restoration, newly planted trees and saplings need to be secured against the wind, otherwise they will have difficulty surviving in the abandoned mine environment. In particular, the mine location is relatively open, and the saplings are affected by strong winds, causing their trunks to shift and thus affecting their later growth. Utility Model Content

[0004] This application provides a mine ecological restoration device for the initial fixation and restoration of trees and plants planted for ecological restoration.

[0005] The above-mentioned technical objective of this application is achieved through the following technical solution:

[0006] A mine ecological restoration device includes a semi-circular first fixing plate and a second fixing plate. One end of the first fixing plate and one end of the second fixing plate are hinged to each other. The first fixing plate and the second fixing plate can form a complete cylinder. The outer surfaces of the first fixing plate and the second fixing plate are both hinged with reinforcing rods through connecting components. One end of the reinforcing rod is hinged to the outer surface of the first fixing plate or the second fixing plate. Arc-shaped fastening plates are slidably provided at the inner arc of the first fixing plate and the second fixing plate. The arc opening of the fastening plate is aligned with the arc opening of the first fixing plate or the second fixing plate.

[0007] By adopting the above technical solution, and by setting up a first fixing plate, a second fixing plate, a reinforcing rod, and a fastening plate, the first fixing plate, the second fixing plate, and the reinforcing rod can provide initial fixation and support for the trees and plants planted for mine ecological restoration. The first fixing plate and the second fixing plate form a ring fixation around the tree or plant, and the reinforcing rod penetrates into the soil to provide support. The hinged reinforcing rod can adjust the support angle, reduce the possibility of the tree or plant swaying and tilting, and create stable conditions for rooting. The sliding fastening plate allows the first fixing plate and the second fixing plate to be used for trees or plants of different thicknesses.

[0008] Optionally, the connecting assembly includes a first mounting cylinder fixed to the outer surfaces of the first and second fixing plates, the axis of the first mounting cylinder being perpendicular to the axis of the first fixing plate, a second mounting cylinder fixed to the end face of the reinforcing rod, a hinge rod slidably disposed inside the first mounting cylinder, a rotating column coaxially rotatably disposed near the end face of the hinge rod close to the second mounting cylinder, a sliding member disposed on the peripheral wall of the rotating column, a sliding groove communicating with both end faces being formed on the inner wall of the second mounting cylinder along its axial direction, the sliding member being adapted to the sliding groove and being able to slide in the sliding groove, a fixing groove being formed on the end face of the second mounting cylinder opposite to the first mounting cylinder, the sliding member being adapted to the fixing groove and being able to be inserted into the fixing groove.

[0009] By adopting the above technical solution, and by setting up a first mounting cylinder, a second mounting cylinder, a hinge rod, a rotating column, and a sliding component, it is possible to achieve detachable hinge connection between the reinforcing rod and the first and second fixed plates, and to adapt and cooperate with the sliding groove and the fixed groove of the sliding component. The angle of the reinforcing rod can be flexibly adjusted. At the same time, the disassembled repair device is convenient for transportation, and the connecting components enable the repair device to be installed quickly, improving the adaptability and convenience of the support.

[0010] Optionally, both the first and second fixing plates are threaded with fastening bolts. The fastening bolts pass through the first or second fixing plate, with their ends located between the fastening plate and the fixing plate. The ends of the fastening bolts are rotatably connected to the protruding surface of the fastening plate. The protruding surface of the fastening plate has a circular rotating hole. The axis of the rotating hole is T-shaped, and the diameter of the opening of the rotating hole is smaller than the diameter of the bottom of the hole. The ends of the fastening bolts are coaxially fixed with a rotating plate that matches the rotating hole. Both the rotating plate and the ends of the fastening bolts are rotatably disposed within the rotating hole.

[0011] By adopting the above technical solution, and by setting fastening bolts, rotating holes and rotating plates, the fastening plate can be moved closer to the tree by rotating the fastening bolts. The matching structure of the rotating plate and the rotating hole ensures that the fastening bolts and the fastening plate maintain a stable rotating connection, allowing the fastening plate to smoothly fit against the tree trunk surface. The force is dispersed through surface contact, which reduces damage to the tree trunk compared to fixing it in place.

[0012] Optionally, guide posts are provided at both ends of the fastening plate protruding from the plate surface. The ends of the guide posts are fixedly connected to the fastening plate, and the guide posts slide into the fixing plate. The axis of the guide posts is parallel to the length direction of the fastening bolts.

[0013] By adopting the above technical solution and setting guide posts, the sliding trajectory of the fastening plate can be limited, preventing the fastening plate from rotating or shifting during movement, ensuring that the fastening plate always moves smoothly in the direction towards the tree trunk, and improving the accuracy and stability of the fixing operation in conjunction with the fastening bolts.

[0014] Optionally, a third thickened portion in an annular shape is coaxially fixed to the end of the hinge rod away from the rotating column. A spring is provided between the third thickened portion and the first mounting cylinder, and the two ends of the spring are fixed to the surfaces opposite to the first mounting cylinder and the third thickened portion, respectively.

[0015] By adopting the above technical solution, and by setting a third thickened part and a spring, the spring's extension and contraction characteristics can be utilized. When the third thickened part is pressed, the spring is compressed, and when it is released, the spring extends and pushes the sliding part into the fixing groove, thus quickly completing the hinged fixing of the reinforcing rod and the fixing plate. At the same time, the elastic force of the spring can enhance the stability of the connection part, improve the installation efficiency and connection reliability.

[0016] Optionally, the end faces of the first fixing plate and the second fixing plate that are hinged to each other are provided with a plurality of first protrusions at even intervals, and the corresponding end face of the second fixing plate is provided with a plurality of second protrusions at even intervals. The first protrusions and the second protrusions are staggered and can be inserted into each other. The first protrusions and the second protrusions are provided with a hinge post, and the first fixing plate and the second fixing plate are hinged to each other through the hinge post.

[0017] By adopting the above technical solution, the first protrusion, the second protrusion, and the hinge post can be used to make the first protrusion and the second protrusion staggered and then stably hinged through the hinge post. The staggered structure improves the connection strength at the hinge point, allowing the first fixing plate and the second fixing plate to rotate and open smoothly, which is convenient for fixing to the outer periphery of trees of different thicknesses.

[0018] Optionally, the surface of the first protrusion facing away from the first fixing plate and the surface of the second protrusion facing away from the second fixing plate are both processed into protruding arc surfaces.

[0019] By adopting the above technical solution, and by setting the first protrusion to be away from the arc surface of the first fixed plate and the second protrusion to be away from the arc surface of the second fixed plate, the contact resistance between the protrusions when the first fixed plate and the second fixed plate rotate can be reduced, making the opening and closing action of the two smoother and reducing the occurrence of jamming during rotation.

[0020] Optionally, a U-shaped operating frame is fixedly connected to the end face of the rotating column away from the hinge rod. Both ends of the operating frame are fixedly connected to the end face of the rotating column, and the U-shaped opening of the operating frame faces the rotating column.

[0021] By adopting the above technical solution and setting up an operating frame, operators can be provided with a convenient force application point to rotate the rotating column, which facilitates quick adjustment of the position of the sliding parts, helps the sliding parts to accurately match the sliding groove and the fixed groove, and improves the efficiency of the installation and disassembly process of the reinforcing rod.

[0022] In summary, this application has the following technical effects:

[0023] 1. By setting up a first fixing plate, a second fixing plate, a reinforcing rod, and a fastening plate, the first fixing plate, the second fixing plate, and the reinforcing rod can provide initial fixing support for the trees and plants planted for mine ecological restoration. The first fixing plate and the second fixing plate form a ring fixation around the tree or plant. The reinforcing rod penetrates into the soil to provide support. The hinged reinforcing rod can adjust the support angle, reduce the possibility of tree and plant swaying and tilting, and create stable conditions for rooting. The sliding fastening plate allows the first fixing plate and the second fixing plate to be used for trees or plants of different thicknesses.

[0024] 2. By setting up a first mounting cylinder, a second mounting cylinder, a hinge rod, a rotating column, and a sliding component, the reinforcing rod can be detachably hinged to the first and second fixed plates, and the sliding component can be matched with the sliding groove and the fixed groove. The angle of the reinforcing rod can be flexibly adjusted. At the same time, the disassembled repair device is convenient for transportation, and the connecting components enable the repair device to be quickly installed, improving the adaptability and convenience of the support.

[0025] 3. By setting fastening bolts, rotating holes, and rotating plates, the fastening plates can be moved closer to the tree by rotating the fastening bolts. The matching structure of the rotating plate and rotating holes ensures that the fastening bolts and fastening plates maintain a stable rotating connection, allowing the fastening plates to smoothly fit against the tree trunk surface. The force is dispersed through surface contact, which reduces damage to the tree trunk compared to a fixed position. Attached Figure Description

[0029] The present application will be further described in detail below with reference to the accompanying drawings.

[0030] This application discloses a mine ecological restoration device, referring to... Figure 1The restoration device includes a fixing structure 1 and a connecting component 2 installed on the fixing structure 1. The fixing structure 1 can fix and support the trees and plants planted in the mine ecological restoration, reduce the possibility of the trees and plants shaking or tilting, increase the root depth, and improve the survival rate.

[0031] Combination Figure 1 and Figure 2 The fixing structure 1 includes a first fixing plate 11 and a second fixing plate 12. Both the first fixing plate 11 and the second fixing plate 12 are metal strip plates with semi-circular sidewalls and curved surfaces. The concave surfaces of the first fixing plate 11 and the second fixing plate 12 are arranged opposite each other. The end faces of the first fixing plate 11 and the second fixing plate 12 can fit together and can form a complete cylinder. One end of the first fixing plate 11 and the end of the adjacent second fixing plate 12 are hinged to each other.

[0032] Combination Figure 1 and Figure 2 The ends of the first fixing plate 11 and the second fixing plate 12 that are hinged to each other are provided with a plurality of square-shaped first protrusions 111 and second protrusions 121 at even intervals. The first protrusions 111 and the second protrusions 121 are staggered and can be inserted into each other. When the first protrusions 111 and the second protrusions 121 are inserted into each other, they are both provided with the same hinge post 13. The hinge post 13 is a cylinder and passes through the side wall of the first fixing plate 11 into the first protrusion 111. The axis of the hinge post 13 is perpendicular to the side wall of the first fixing plate 11. The ends of the first fixing plate 11 and the second fixing plate 12 are hinged to each other through the hinge post 13.

[0033] Combination Figure 1 and Figure 2 The first protrusion 111 is machined into a protruding arc surface away from the surface of the first fixing plate 11, and the second protrusion 121 is machined into a protruding arc surface away from the surface of the second fixing plate 12. The arc surface facilitates the rotation of the first fixing plate 11 and the second fixing plate 12 and reduces the possibility of jamming.

[0034] Combination Figure 1 and Figure 2 Sliding fastening plates 14 are provided in the inner arc of the first fixing plate 11 and the inner arc of the second fixing plate 12. The fastening plates 14 are metal strip plates with curved surfaces. The arc opening of the fastening plate 14 in the inner arc of the first fixing plate 11 is aligned with the arc opening of the first fixing plate 11, and the arc opening of the fastening plate 14 in the inner arc of the second fixing plate 12 is aligned with the arc opening of the first fixing plate 11.

[0035] Combination Figure 1 and Figure 2Guide posts 141 are provided at both ends of the protruding surface of the fastening plate 14. The guide posts 141 are cylindrical and their ends are fixed to the surface of the fastening plate 14. The guide posts 141 slide through the first fixed plate 11 or the second fixed plate 12. The axis of the guide posts 141 is perpendicular to the end face of the first fixed plate 11. The guide posts 141 can restrict the sliding trajectory of the fastening plate 14 and reduce the possibility of rotation of the sliding plate. Both the first fixed plate 11 and the second fixed plate 12 are threadedly connected with fastening bolts 15. The fastening bolts 15 pass through the first fixed plate 11 or the second fixed plate 12, and their ends are located between the fixed plate and the fastening plate 14. The fastening bolts 15 are located between the guide posts 141 at both ends of the surface of the fastening plate 14, and the length direction of the fastening bolts 15 is parallel to the axis of the guide posts 141.

[0036] Combination Figure 1 and Figure 2 The fastening plate 14 has a circular rotating hole 142 at the corresponding position of the protruding plate surface. The rotating hole 142 is T-shaped in the axial direction. The diameter of the opening of the rotating hole 142 is smaller than the diameter of the bottom of the hole. The end of the fastening bolt 15 is coaxially fixed with a circular rotating plate 151. The rotating plate 151 is adapted to the rotating hole 142. Both the rotating plate 151 and the end of the fastening bolt 15 are rotatably set in the rotating hole 142. The rotating plate 151 can reduce the possibility of the fastening plate 14 and the fastening bolt 15 separating. It is convenient to drive the fastening plate 14 to move along the axial direction of the guide post 141 when the fastening bolt 15 is rotated.

[0037] Combination Figure 1 and Figure 2 When the fixing structure 1 is fitted around the tree, the fastening plate 14 is moved closer to the tree by rotating the fastening bolt 15. The concave surface of the fastening plate 14 abuts against the outer perimeter of the tree. Compared with the set screw, the fastening plate 14 can reduce damage to the tree trunk. The outer surfaces of the other ends of the first fixing plate 11 and the second fixing plate 12 are connected to each other by the buckle 16, which facilitates the reuse of the repair device.

[0038] Combination Figure 1 and Figure 2 The outer surfaces of the first fixing plate 11 and the second fixing plate 12 are hinged with reinforcing rods 17 via connecting assembly 2. The reinforcing rods 17 are round rods, and four rods are provided. One end of each reinforcing rod 17 is rectangularly distributed around the outer circumference of the cylinder formed by the first fixing plate 11 and the second fixing plate 12. The ends of the reinforcing rods 17 furthest from the first fixing plate 11 are processed into a tapered shape to facilitate insertion into the ground. The reinforcing rods 17 are used to support trees or plants, reducing the possibility of swaying or tilting.

[0039] Combination Figure 1 and Figure 2The connecting component 2 includes a first mounting cylinder 21 and a second mounting cylinder 22. Both the first mounting cylinder 21 and the second mounting cylinder 22 are cylindrical. The outer peripheral wall of the first mounting cylinder 21 is fixed to the corresponding position of the outer plate faces of the first fixing plate 11 and the second fixing plate 12. The outer peripheral wall of the second mounting cylinder 22 is fixed to the end face of the reinforcing rod 17. The axis of the first mounting cylinder 21 is perpendicular to the axis of the first fixing plate 11, and the axes of the first mounting cylinder 21 and the second mounting cylinder 22 are parallel to each other.

[0040] Combination Figure 1 and Figure 2 A hinge rod 23 is slidably disposed inside the first mounting cylinder 21. The hinge rod 23 is a round rod. The peripheral wall of the hinge rod 23 is slidably attached to the inner peripheral wall of the first mounting cylinder 21. A third thickened part 231 in an annular shape is coaxially fixed to the end wall of the hinge rod 23 away from the second mounting cylinder 22. A spring is disposed between the third thickened part 231 and the first mounting cylinder 21. The spring is sleeved on the peripheral wall of the hinge rod 23. The two ends of the spring are fixed to the surfaces opposite to the first mounting cylinder 21 and the third thickened part 231, respectively.

[0041] Combination Figure 1 and Figure 2 A rotating column 24 is rotatably mounted on the end face of the hinge rod 23 away from the third thickened portion 231. The rotating column 24 is cylindrical and coaxially arranged with the hinge rod 23, with its peripheral wall flush with that of the hinge rod 23. A rotating shaft (not shown in the figure) is fixedly connected to the end face of the hinge rod 23, and the rotating shaft passes through the rotating column 24, rotatably positioning the rotating column 24 on the end face of the hinge rod 23. A sliding member 241 is fixedly connected to the peripheral wall of the rotating column 24. The sliding member 241 is a block, and its surface away from the first mounting cylinder 21 is flush with the end face of the rotating column 24 away from the first mounting cylinder 21.

[0042] Combination Figure 1 and Figure 2 The inner peripheral wall of the second mounting cylinder 22 is provided with a sliding groove 221 along its axial direction. The sliding groove 221 has openings on both ends of the second mounting cylinder 22. The sliding groove 221 is adapted to the sliding member 241, and the sliding member 241 can be slidably disposed in the sliding groove 221. The end face of the second mounting cylinder 22 opposite to the first mounting cylinder 21 is provided with a fixing groove 222 spaced apart from the sliding groove 221. The fixing groove 222 is adapted to the sliding member 241, and the sliding member 241 can be inserted into the fixing groove 222.

[0043] Combination Figure 1 and Figure 2When installing the reinforcing rod 17, the rotating column 24 and the hinge rod 23 are inserted into the second mounting cylinder 22, and the sliding member 241 slides in the sliding groove 221. When the surface of the sliding member 241 facing away from the first mounting cylinder 21 is flush with the surface of the second mounting cylinder 22 facing away from the first mounting cylinder 21, the opposite end faces of the first mounting cylinder 21 and the second mounting cylinder 22 abut against each other, and the third thickened part 231 is pressed towards the first mounting cylinder 21. The third thickened part 231 compresses the spring, causing the sliding member 241 to protrude from the second mounting cylinder 22. The rotating column 24 is rotated to rotate the sliding member 241 to the fixing groove 222. The third thickened part 231 is released, the spring extends, and the sliding member 241 is inserted into the fixing groove 222, thus hinged the reinforcing rod 17 to the first fixing plate 11 and the second fixing plate 12. This facilitates angle adjustment of the reinforcing rod 17 and improves the support effect.

[0044] Combination Figure 1 and Figure 2 An operating frame 242 is fixedly connected to the end face of the rotating column 24 away from the first mounting cylinder 21. The operating frame 242 is U-shaped, and both ends of the operating frame 242 are fixedly connected to the end face of the rotating column 24. The U-shaped opening of the operating frame 242 faces the rotating column 24 and is parallel to the axis of the rotating column 24, allowing the operating frame 242 to facilitate the rotation of the rotating column 24. The connecting assembly 2 allows the reinforcing rod 17 to be detachably connected to the first fixing plate 11 and the second fixing plate 12, facilitating transportation. At the same time, the connecting assembly 2 enables the reinforcing rod 17 to be quickly hinged to the first fixing plate 11 and the second fixing plate 12.
