Description

Technical Field

[0001] The invention relates to the technical field of ecological restoration equipment, and in particular to a steep slope ecological restoration device. Background Art

[0002] The main purpose of slope ecological restoration is to protect the environment, prevent soil erosion, improve slope stability, and promote ecological balance. Because the slope itself is unstable, it is not only prone to soil erosion, but also prone to collapse and landslides, especially steep slopes. Specifically, due to the exposure of the slope and insufficient vegetation coverage, steep slopes often become the hardest hit areas of soil erosion and soil erosion. Through ecological restoration, vegetation coverage can be increased and the soil's water retention capacity can be improved, thereby improving the slope's ecological environment, maintaining ecological balance, and providing protection for the biodiversity of the surrounding areas. Steep slope ecological restoration has the effect of improving slope stability. Due to the complex structure of the slope and the diverse geological conditions, the stability of steep slopes is easily affected by a variety of factors. Once unstable, it may cause natural disasters such as landslides and mudslides, posing a serious threat to people's lives and property.

[0003] As one of the key means of ecological restoration of steep slopes, vegetation coverage and soil improvement measures can effectively prevent water from scouring and eroding the slope surface, reduce soil erosion, protect soil resources, and improve the stability of steep slopes. The basis of all this lies in how to prevent soil fixation on slopes, especially steep slopes that are more prone to soil loss. This is the primary task of slope ecological restoration.

[0004] The conventional method is to plant green plants on the slopes to conserve water and soil, prevent large-scale landslides, and improve the ecological environment. However, for steep slopes, due to their inherent steepness, the soil is more likely to slide. Therefore, relying solely on manual planting of green plants, especially in the early stages of steep slope construction and maintenance, when the initial construction of the slope is completed, due to the lack of or no plant cover, the structural stability itself is extremely poor. Direct sowing to create a green belt can easily cause the soil to be lost before the construction is successful. This not only fails to lock the soil and prevent landslides to improve the ecology, but also causes the originally sown green plant seeds, fertilizers or improvement elements to slide and be lost together.

[0005] On the other hand, the steep slope itself has a large inclination, the terrain is dangerous, and construction is difficult. Traditional operations such as improving the soil and creating a green environment require people to stand on the steep slope for a long time, which is very dangerous and very laborious.

[0006] Therefore, in order to plant adaptable and fast-growing plant species and carry out proper maintenance and management to form an ecological landscape with grass, flowers and shrubs, beautify the environment and consolidate the stability of the steep slopes, it is necessary to design a safer and more reliable special equipment for steep slope ecological restoration.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0033] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0035] See also Figure 1-Figure 2The present invention provides a technical solution: a structure of a steep slope ecological restoration device includes a rectangular soil storage frame 1 that can be embedded in the soil of a steep slope 15. The soil storage frame 1 includes a horizontal plate 3 and a vertical plate 2. The two plates can be made of thin stainless steel plates and can be provided with a number of small water-permeable holes. During assembly, the horizontal plate 3 and the vertical plate 2 are fixedly connected vertically and crosswise to form a frame structure similar to a grid, so that the soil storage frame 1 divides the surface soil of the slope into a number of rectangular areas, each of which plays an independent role in preventing soil loss. In addition, at least the bottom of the top and bottom of the horizontal plate 3 and the vertical plate 2 is provided with a sharp edge for cutting into the soil, so that the soil storage frame 1 can be wedged into the soil. When a sharp edge is also provided at the top, it is convenient to take out the soil storage frame 1 at that time. One of the particularly critical designs is that in this embodiment, a column 4 is specially provided at each of the four corners of the soil storage frame 1. The column 4 can be arranged perpendicular to the slope surface, and one is located at the top of the slope, and the other is located at the bottom of the slope or at a certain height position of the designated slope surface. At the same time, a screw rod 8 must be coaxially rotatably installed in at least two columns 4, and the screw rod 8 can rotate in situ in the column 4. In specific production, the column hole cross section of the column 4 where the screw rod 8 is located is rectangular, and a thread block 9 is threadedly sleeved on the screw rod 8. Correspondingly, this thread block 9 is a rectangular block structure that slides axially with the column hole, so that it can form a screw mechanism together with the screw rod 8 and move axially. As for the transmission of the screw rod 8, one end of the screw rod 8 can be extended out of the top of the column 4 and can be connected to a driving motor. Once the driving motor is installed on the column 4, the threaded block 9 can be moved axially, and then the soil storage frame 1 fixed thereto can be moved along the depth direction of the slope soil, for example, vertically along the slope surface, and the soil storage frame 1 can be installed into the surface soil of the slope, and then the soil on the steep slope 15 can be fixed, so as to avoid the situation where the green plants that conserve water and soil have not been planted or have withered, resulting in a large amount of water and soil loss on the slope, causing ecological imbalance and affecting the stability of the steep slope 15, and at the same time laying the foundation for creating a green ecological landscape on the slope.

[0036] In this embodiment, refer to Figure 2 In the structure shown, a flange 10 is fixed at the top of the column 4. Accordingly, the drive motor is also an electric motor with a connecting flange, so that the connecting flange and the flange 10 are conveniently connected together through flange bolts, so that the drive motor and the column 4 can be detachably connected. When in use, it can be assembled and disassembled at any time as needed, without having to place important equipment such as the motor in the field. During specific installation, the end face of one end of the screw rod 8 is provided with a socket with a keyway, and the main shaft end of the drive motor is fixed with a key, so that when the main shaft is inserted into the socket, the transmission connection between the main shaft and the screw rod 8 is well realized, and it is convenient to disassemble.

[0037] In this embodiment, the flange 10 is detachably connected to a mounting base 11 with a flange plate, and the purpose is also to be assembled and disassembled at any time according to needs. Figure 1 A guide rod 12 is rotatably mounted between two mounting seats 11 along the length of the slope, that is, one can be at the top of the slope and the other at the bottom of the slope, and the two can be arranged in parallel. At the same time, a slide seat 13 is also required to be axially slidably mounted on the guide rod 12, that is, the slide seat 13 can move axially along the guide rod 12, that is, move horizontally above the slope. Another key design structure is: Figure 1 A feeding pipe 5 arranged along the inclination direction of the slope is particularly fixed between the two slide seats 13 located at the top and bottom of the slope. The wall of the feeding pipe 5 is provided with a plurality of spaced drop holes 501 along its length direction. The drop holes 501 can be evenly spaced, and a screw conveying shaft 6 is coaxially rotatably installed in the feeding pipe 5, so that when the screw conveying shaft 6 rotates, the seeds or fertilizers in the feeding pipe 5 are sprinkled into the soil of the slope through the drop holes 501 for initial or supplementary sowing of green plants. As the spiral conveying shaft 6 rotates, the seeds will gradually move forward and then fall into the soil on the slope. In order to achieve full coverage, this embodiment specifically installs a strip tile 7 that fits the feeding tube 5 and is rotatable on the outside of the feeding tube 5. The strip tile 7 is provided with a through hole. When the strip tile 7 rotates to a position where the through hole and the drop hole 501 are aligned or completely offset, the strip tile 7 can be fixed to the feeding tube 5 as a whole. That is, when the through hole and the drop hole 501 are aligned, the seeds fall. This is generally when the seeds have been transported in the feeding tube 5. After a period of time, the two are aligned so that seeds can be dropped from all the drop holes 501 at the same time, which is convenient for comprehensive sowing when the feeding tube 5 is axially translated along the guide rod 12; in specific practice, an overflow hole (not shown in the figure) can be set at the end of the seed transportation in the feeding tube 5. When the seeds reach this overflow hole, it means that the seeds have filled the entire feeding tube 5. At this time, the through hole and the drop hole 501 can be directly adjusted from the completely staggered closed position to the discharge and sowing position where the through hole and the drop hole 501 are aligned.

[0038] In this embodiment, Figure 2-Figure 6 A mounting portion 16 is provided at the end of the slide seat 13, and a U-shaped mounting groove 1601 is provided on the mounting portion 16. The mounting groove 1601 allows the positioning disc 17 at the end of the feeding tube 5 to slide to the bottom, and the side of the mounting groove 1601 has a U-shaped notch 1602 for the end of the feeding tube 5 to pass through, so that the feeding tube 5 can be installed in place in cooperation with the mounting portion 16.

[0039] In this embodiment, Figure 2-Figure 6The side of the mounting portion 16 is integrally provided with a boss 18, and a sliding pin 20 is coaxially connected to the boss 18 through a return spring 21, that is, the sliding pin 20 is elastically telescopically installed, and in the assembled state, that is, when the end of the feed pipe 5 has not yet been installed into the mounting portion 16, as Figure 5 As shown, the hemispherical surface 2001 of the end of the sliding pin 20 extends into the mounting groove 1601. The purpose of this is that when the feeding tube 5 is installed, when the positioning disc 17 slides into the mounting groove 1601, the end of the sliding pin 20 can be pressed out of the mounting groove 1601 through the hemispherical surface 2001 and returned to the mounting portion 16 and the boss 18, and the hemispherical surface 2001 is kept in sliding contact with the end face of the positioning disc 17 at this time. Then, during the rotation of the feeding tube 5, the end of the sliding pin 20 can be rebounded into the perforation of the positioning disc 17, as shown in FIG. Figure 3 , Figure 4 , Figure 6 As shown, it is inserted into the corresponding blind hole 23 on the inner wall of the mounting groove 1601, so as to realize the clamping fixation of the positioning disc 17 and the mounting portion 16, and realize the installation of the feeding pipe 5. Moreover, at this time, the blanking hole 501 is preferably facing the slope surface of the slope.

[0040] In this embodiment, Figure 4 As shown, the free end of the boss 18 is screwed in by a locking bolt 19, which coaxially passes through the return spring 21, and can axially squeeze the sliding pin 20 to fix it, that is, keep the sliding pin 20 always inserted into the above-mentioned blind hole 23. When disassembling, it is only necessary to loosen or unscrew the locking bolt 19 so that the sliding pin 20 pops out of the blind hole 23 and the positioning disk 17, or after unscrewing the locking bolt 19, rotate the positioning disk 17 so that the hemispherical surface 2001 leaves the hole on the positioning disk 17, and then pull out the positioning disk 17 to take out the feeding tube 5.

[0041] In this embodiment, Figure 3 and Figure 8 In the above embodiment, a fan-shaped plate 24 is coaxially fixed to the end of the strip tile plate 7. The fan-shaped plate 24 has an arc-shaped strip hole 26 along its circumferential direction. The arc-shaped strip hole 26 is penetrated by a T-bolt 22 installed in the side of the mounting portion 16. The nut of the T-bolt 22 is slidably installed in the arc-shaped groove on the side of the mounting portion 16, so that the T-bolt 22 can be fastened with the locking nut 25 at the opening of the arc-shaped strip hole 26. The purpose of this structural design is to rotate the strip tile plate 7 around the outer wall of the feeding pipe 5 to two extreme positions, namely the two ends of the above-mentioned arc-shaped groove, and then correspond to the two positions of alignment and complete offset between the blanking hole 501 and the through hole.

[0042] In this embodiment, the guide rod 12 mentioned is specifically a lead screw, which is rotatably installed in the mounting seat 11. After the end of the lead screw is exposed from the mounting seat 11, it can be connected to an external power motor to drive the lead screw to rotate, and the slide 13 is threadedly sleeved with the lead screw. In addition, a limit rod (not shown in the figure) can be adaptively arranged. The limit rod is arranged parallel to the lead screw, and both ends are fixed on two opposite mounting seats 11 to form a lead screw mechanism, which drives the slide 13 and the feeding tube 5 to move in a straight line scanning manner above the slope surface of the steep slope 15 to perform operations such as sowing or fertilizing, spraying trace elements, etc. to improve the ecology of green plants.

[0043] Finally, as a specific implementation detail, the threaded block 9 can be moved out of the column 4, that is, the threaded block 9 can slide out of the column 4 axially, and can slide out automatically or manually. The main purpose is to cooperate with the rotary tillage component for improving the soil structure. For example, the surface soil can be rotary tilled and crushed with the rotary tillage component to sow or spray the growth elements of green plants, and then the soil storage frame 1 can be installed in the soil by screwing in the threaded block 9. At this time, it is also easier to install the soil storage frame 1. Specifically, if Fig. 9 As shown, outside the wall of the feed pipe 5, a plurality of rotary tillage assemblies are fixedly connected thereto, and two rotary tillage assemblies are located on two opposite sides below the feed pipe 5. Specifically, the rotary tillage assembly includes a rotating shaft 28 and a reamer 29 for crushing the soil, and the rotating shaft 28 is fixedly connected to the outer wall of the feed pipe 5 through a telescopic connecting rod 27 to ensure the effective depth of rotary tillage. The rotating shaft 28 can be connected to a rotary tillage motor 30 for transmission, and the reamer 29 is arranged along the axial direction of the rotating shaft 28, which can quickly and fully rotary cut the surface soil of the slope to improve the soil structure.
