Description

Technical Field

[0001] This invention relates to the technical field of ecological restoration equipment, and in particular to a seeding device for ecological restoration of mine yard slopes. Background Technology

[0002] Mining is an activity that has a huge impact on the natural environment. With the continuous development of mineral resources, many mines leave behind a lot of abandoned land after completing their mining tasks, including tailings ponds, abandoned mine pits, and piles of waste rock. These abandoned lands not only occupy a lot of land resources, but may also cause serious environmental problems, such as soil erosion, geological disasters, water pollution, and loss of biodiversity.

[0003] In order to mitigate the negative impacts of mining, ecological restoration of mines has gradually gained attention. The goal of ecological restoration is to restore the ecological environment of damaged areas through a series of technical measures, so that they can support plant growth again and eventually form a stable ecosystem. Among them, the ecological restoration of slopes and stockpiles is particularly important because they are often the main sources of soil erosion and geological disasters.

[0004] In the process of ecological restoration, a mixture of seeds, fertilizers, soil stabilizers and other additives is usually sprayed onto the slope to allow the seeds to take root and germinate and stabilize the slope. However, because the spraying method is used directly, the roots of the plant seeds cannot penetrate deep into the slope, resulting in poor soil stabilization and low seed survival rate, thus having a poor effect on ecological restoration. Summary of the Invention

[0005] To solve the above-mentioned technical problems, the present invention provides a seeding device for ecological restoration of mine stockpile slopes, the specific technical solution of which is as follows:

[0006] A soil turning device for ecological restoration of mine stockpile slopes includes a telescopic boom, a turning mechanism, and two sets of roller mechanisms. The telescopic boom provides power for the movement of the turning mechanism and the roller mechanisms. The telescopic boom is connected to the turning mechanism, which is used to turn the soil on the slope. The two sets of roller mechanisms are located on both sides of the turning mechanism, and the telescopic boom uses the roller mechanisms to propel the turning mechanism to move on the slope.

[0007] The sowing mechanism consists of a swing mechanism and multiple plow blades mounted on the swing mechanism. The swing mechanism is used to push the plow blades into the ground and turn the soil. Each plow blade is equipped with a discharge pipe, which is used to send plant seeds into the soil trenches turned by the plow blade.

[0008] Furthermore, the rewinding mechanism also includes a central sleeve for support, a telescopic boom fixedly connected to the central sleeve, and two vertical plates opposite each other at the bottom of the central sleeve;

[0009] The swing mechanism includes a first transmission wheel and a second transmission wheel rotatably mounted on each vertical plate. The two first transmission wheels on the two vertical plates are connected by a first eccentric column, which is eccentric on the first transmission wheel. The two second transmission wheels on the two vertical plates are connected by a second eccentric column, which is eccentric on the second transmission wheel. Multiple connecting sleeves are rotatably mounted on the first eccentric column. The end of the plow blade slides through the second eccentric column and is fixed to the outer wall of the connecting sleeve.

[0010] The first drive wheel and the second drive wheel mesh with each other.

[0011] Furthermore, a spindle is rotatably inserted in the middle of the central sleeve, and a third transmission wheel is provided at both ends of the spindle. A fourth transmission wheel is driven on each third transmission wheel, and the fourth transmission wheel is rotatably mounted on the vertical plate.

[0012] The third transmission wheel is connected to the roller mechanism, and the fourth transmission wheel is connected to the first transmission wheel.

[0013] Furthermore, the flipping mechanism also includes a feeding chamber fixed on two vertical plates. The top of the feeding chamber is provided with a feeding pipe for supplying materials into the feeding chamber. The bottom of the feeding chamber is connected to multiple guide pipes, which are respectively connected to multiple discharge pipes.

[0014] The feeding chamber is equipped with an opening and closing mechanism, which is used to control the flow of materials in the feeding chamber.

[0015] Furthermore, the opening and closing mechanism includes a sliding plate disposed inside the feeding chamber and a partition that slides horizontally through the feeding chamber. The partition and the sliding plate are parallel and in contact with each other. Both the partition and the sliding plate are provided with multiple notches, and the notches on the partition and the sliding plate are staggered. One end of the partition is set as an inclined surface, and the inclined surface faces the first eccentric column. The other end of the partition is provided with a limiting edge, which is connected to the feeding chamber through a first spring piece.

[0016] Furthermore, each of the feed tubes is provided with a collar, which is connected to the feed chamber via an outer support arm. The outer support arm is provided with a second spring plate, which is connected to the feed chamber.

[0017] Furthermore, it also includes a buckle plate fastened to the outside of the third transmission wheel. The inner circumference of the buckle plate is connected to the outer wall of the third transmission wheel. A support ring is coaxially arranged inside the buckle plate. An arc-shaped groove is slidably provided on the support ring. The arc-shaped groove is fixedly connected to the spindle.

[0018] The buckle plate has its axis located below the spindle axis, and multiple arc-shaped panels are installed on the buckle plate.

[0019] Furthermore, the multiple arc-shaped panels on the mounting plate are arranged in a ring, and adjacent arc-shaped panels are connected by elastic inserts. That is, one end of the elastic insert is fixed to one arc-shaped panel, and the other end of the elastic insert slides into another arc-shaped panel.

[0020] The arc-shaped panel is provided with an extension plate, which is slidably mounted on the buckle plate. The extension plate slides in the radial direction of the buckle plate. An adjustment plate is rotatably provided in the middle of the buckle plate. The adjustment plate is connected to each extension plate by an adjustment arm, and the adjustment plate is fixed to the buckle plate by a lock nut.

[0021] The advantages of this invention are:

[0022] By turning over the soil with a plow blade to form trenches, the discharge pipe delivers seeds and other additives directly into the trenches. This ensures that the seeds remain within the soil, preventing them from drying out due to wind and sun exposure or being eaten by animals, thus improving seed survival rates. Furthermore, once buried underground, the seeds' root systems penetrate deeper into the soil as the plants grow, enhancing soil stability and effectively preventing soil erosion and geological disasters. In conclusion, this seed-turning device effectively solves the problem of low seed survival rates under traditional spraying methods while improving soil stability, making it an efficient, economical, and environmentally friendly technical solution for mine ecological restoration.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0034] In the description of this invention, it should be noted that the orientations or positional relationships indicated by terms such as "center", "up", "down", "left", "right", "vertical", "horizontal", "inner", and "outer" are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0035] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. This embodiment is written in a progressive manner.

[0036] like Figures 1 to 4As shown, the soil turning device for ecological restoration of mine stockpile slopes of the present invention includes a telescopic boom 1, a turning mechanism 2 and two sets of roller mechanisms 3. The telescopic boom 1 is used to provide power for the movement of the turning mechanism 2 and the roller mechanisms 3. The telescopic boom 1 is connected to the turning mechanism 2. The turning mechanism 2 is used to turn the soil on the slope. The two sets of roller mechanisms 3 are respectively arranged on both sides of the turning mechanism 2, and the telescopic boom 1 pushes the turning mechanism 2 to move on the slope with the help of the roller mechanisms 3.

[0037] The sowing mechanism 2 consists of a swing mechanism and multiple plow blades 4 mounted on the swing mechanism. The swing mechanism is used to push the plow blades 4 into the ground and turn the soil. Each plow blade 4 is equipped with a discharge pipe 5, which is used to send plant seeds into the soil trenches turned by the plow blade 4.

[0038] In detail, one end of the telescopic boom 1 is mounted on the locomotive, and the other end is connected to the sowing mechanism 2. Since the sowing mechanism 2 needs to move on the slope, the telescopic boom 1 is required to provide it with propulsion and support. When the telescopic boom 1 extends or retracts, it can push the sowing mechanism 2 to move along the slope, and the roller mechanism 3 rolls on the slope, thereby realizing the sowing of the slope soil. Each plow blade 4 on the sowing mechanism 2 has a straight end and an arc end. The arc part serves as the main structure for turning the soil. When it is shoveled into the ground, as the sowing mechanism 2 moves with the roller mechanism 3, a trench appears on the slope. The discharge pipe 5 can then guide a mixture of seeds, fertilizer, soil stabilizer, and other additives into the trench, thereby burying the seeds underground. Since the sowing work is carried out on the slope, the slipping soil can automatically cover the trench, thus preventing the seeds from being exposed.

[0039] By turning over the soil with the plow blade 4 and forming trenches, the discharge pipe 5 directly delivers seeds and other additives into the trenches. This ensures that the seeds remain within the soil, preventing them from drying out due to wind and sun exposure or being eaten by animals, thus improving seed survival rate. Furthermore, after the seeds are buried underground, as the plants grow, their roots can penetrate deeper into the soil, enhancing soil stability and effectively preventing soil erosion and geological disasters. In summary, this seed-turning device effectively solves the problem of low seed survival rate under traditional spraying methods while improving soil stability, making it an efficient, economical, and environmentally friendly technical solution for mine ecological restoration.

[0040] like Figure 4 As shown, the re-broadcasting mechanism 2 also includes a central sleeve 6 for support, the telescopic boom 1 is fixedly connected to the central sleeve 6, and two vertical plates 7 are arranged opposite each other at the bottom of the central sleeve 6;

[0041] The swing mechanism includes a first transmission wheel 8 and a second transmission wheel 9 rotatably mounted on each vertical plate 7. The two first transmission wheels 8 on the two vertical plates 7 are connected by a first eccentric column 10, which is eccentric on the first transmission wheel 8. The two second transmission wheels 9 on the two vertical plates 7 are connected by a second eccentric column 12, which is eccentric on the second transmission wheel 9. A plurality of connecting sleeves 11 are rotatably mounted on the first eccentric column 10. The end of the plow blade 4 slides through the second eccentric column 12 and is fixed to the outer wall of the connecting sleeve 11.

[0042] The first transmission wheel 8 and the second transmission wheel 9 mesh with each other.

[0043] In detail, the central sleeve 6 and the vertical plate 7 provide support for the first transmission wheel 8 and the second transmission wheel 9. When the first transmission wheel 8 rotates, it drives the second transmission wheel 9 to rotate synchronously in the opposite direction. The first eccentric column 10 and the second eccentric column 12 both move eccentrically on the corresponding first transmission wheel 8 and second transmission wheel 9. This allows the curved part of the plow blade 4 to tilt and shovel into the soil on the slope at the tail of the sowing mechanism 2 as it moves on the slope. As the sowing mechanism 2 moves, the curved part of the plow blade 4 moves a small distance, at which point the trench is exposed. The discharge pipe 5 guides the seeds into the trench. Then the plow blade 4 moves in the opposite arc and is lifted, releasing the soil on it into the trench, thus achieving the effect of automatic burial. This avoids large-scale soil movement on the slope and prevents landslides. It facilitates sowing while protecting the overall structure of the slope, avoiding landslides that occur when large-scale plowing is carried out on the slope in traditional methods.

[0044] It should be noted that since both the first eccentric column 10 and the second eccentric column 12 are eccentrically moving, the first eccentric column 10 and the second eccentric column 12 can guide the straight part of the plow blade 4. The straight part of the plow blade 4 can slide on the second eccentric column 12, and the plow blade 4 will drive the connecting sleeve 11 to rotate on the first eccentric column 10. Thus, by using this simple structure, the working process of the plow blade 4 from turning over the soil to releasing the soil to cover the trench is realized.

[0045] It can be seen that because the first transmission wheel 8 and the second transmission wheel 9 rotate continuously, the plow blade 4 can repeatedly cut short-distance trenches on the slope, thus avoiding damage to the slope when the plow blade 4 cuts long-distance trenches.

[0046] like Figure 4 As shown, a spindle 13 is inserted and rotated in the middle of the central sleeve 6. A third transmission wheel 14 is provided at both ends of the spindle 13. A fourth transmission wheel 15 is driven on each third transmission wheel 14. The fourth transmission wheel 15 is rotatably mounted on the vertical plate 7.

[0047] The third transmission wheel 14 is connected to the roller mechanism 3, and the fourth transmission wheel 15 is connected to the first transmission wheel 8.

[0048] In detail, when the roller mechanism 3 rolls on the slope, since the roller mechanism 3 is connected to the third transmission wheel 14, the roller mechanism 3 will drive the third transmission wheel 14 to rotate. At this time, the third transmission wheel 14 will drive the first transmission wheel 8 to rotate through the fourth transmission wheel 15, thereby driving the equipment to run. The spindle 13 provides support for the third transmission wheel 14.

[0049] like Figure 5 As shown, the flipping mechanism 2 also includes a feeding chamber 16 fixed on two vertical plates 7. The top of the feeding chamber 16 is provided with a feeding pipe 17 for supplying materials into the feeding chamber 16. The bottom of the feeding chamber 16 is connected to a plurality of guide pipes 18, which are respectively connected to a plurality of discharge pipes 5.

[0050] The feeding chamber 16 is equipped with an opening and closing mechanism, which is used to control the flow of materials within the feeding chamber 16.

[0051] In detail, the material mixed with seeds, fertilizers, additives and other substances can be fed into the feeding chamber 16 through the feeding pipe 17. The opening and closing mechanism in the feeding chamber 16 is used to control the flow of the material in the feeding chamber 16. When the plow blade 4 opens a trench on the slope, the opening and closing mechanism is opened, and the material flows downward in the feeding chamber 16 and is discharged into the discharge pipe 5 through the guide pipe 18. The material in the discharge pipe 5 is naturally discharged into the trench. During the process of the material flowing in the guide pipe 18 and the discharge pipe 5, the plow blade 4 opens a trench on the slope. That is, the trench opening work and the material supply work are carried out simultaneously.

[0052] like Figure 6 As shown, the opening and closing mechanism includes a sliding plate 20 disposed inside the feeding chamber 16 and a partition 19 that slides horizontally through the feeding chamber 16. The partition 19 is parallel to and in contact with the sliding plate 20. Both the partition 19 and the sliding plate 20 are provided with multiple notches 21, and the notches 21 on the partition 19 and the sliding plate 20 are staggered. One end of the partition 19 is set as an inclined surface, and the inclined surface faces the first eccentric column 10. The other end of the partition 19 is provided with a limiting edge 22, and the limiting edge 22 is connected to the feeding chamber 16 through a first spring piece 23.

[0053] In detail, in the natural state, under the thrust of the first spring 23, the limiting edge 22 abuts against the side wall of the feeding chamber 16. At this time, the position of the partition 19 is fixed, and the positions of the notch 21 on the partition 19 and the notch 21 on the slide plate 20 are staggered. The opening and closing mechanism seals the feeding chamber 16. When the first eccentric column 10 moves to the inclined surface position of the partition 19, the connecting sleeve 11 on the first eccentric column 10 contacts the inclined surface and pushes the partition 19 to move. At this time, the partition 19 slides on the feeding chamber 16, and the notch 21 on the partition 19 aligns with the notch 21 on the slide plate 20. The material flows downward through the notch 21 and enters the guide pipe 18, thereby realizing the automatic control of seed supply. In addition, this structure can improve the synchronization of trench opening and seed discharge, reduce the number of power sources, and simplify the structure and operation.

[0054] like Figure 5 As shown, each of the feed tubes 18 is provided with a collar 24, which is connected to the feed chamber 16 via an outer support arm 25. The outer support arm 25 is provided with a second spring piece 26, which is connected to the feed chamber 16.

[0055] In detail, since the plow blade 4 and the discharge pipe 5 need to repeatedly perform arc-shaped movements, the guide pipe 18 needs to frequently change its shape. At this time, in order to avoid the guide pipe 18 from contacting or getting tangled on the second eccentric column 12, the collar 24 and the outer support arm 25 are used to provide support for the guide pipe 18. That is, the second spring plate 26 provides elastic force to the outer support arm 25, so that the outer support arm 25 and the collar 24 support the guide pipe 18. One end of the outer support arm 25 is rotatably connected to the collar 24, and the other end of the outer support arm 25 is rotatably connected to the feeding chamber 16.

[0056] like Figure 7 As shown, it also includes a buckle plate 27 fastened to the outside of the third transmission wheel 14. The inner circumference of the buckle plate 27 is connected to the outer wall of the third transmission wheel 14. A support ring 28 is coaxially arranged inside the buckle plate 27. An arc-shaped groove 29 is slidably provided on the support ring 28. The arc-shaped groove 29 is fixedly connected to the spindle 13.

[0057] Among them, the axis of the buckle plate 27 is located below the axis of the spindle 13, and multiple arc-shaped panels 30 are provided on the buckle plate 27.

[0058] In detail, the buckle plate 27 can roll on the slope through multiple arc-shaped plates 30. The support ring 28 and the arc-shaped slide 29 can support and connect the mandrel 13 and the buckle plate 27. Since the axis of the buckle plate 27 is located below the axis of the mandrel 13, the diameter of the buckle plate 27 can be minimized. This can reduce the size of the equipment and make the equipment more convenient and flexible. It is not necessary to make the buckle plate 27 coaxial with the mandrel 13, which would result in a larger diameter of the buckle plate 27, making it inconvenient to transport.

[0059] When multiple curved panels 30 move on the slope, the buckle plate 27 rotates, and the buckle plate 27 drives the support ring 28 to slide on the curved slide groove 29. The buckle plate 27 simultaneously drives the third transmission wheel 14 to rotate.

[0060] like Figure 2 As shown, the multiple arc-shaped panels 30 on the buckle plate 27 are arranged in a ring. Adjacent arc-shaped panels 30 are connected by an elastic insert 31. That is, one end of the elastic insert 31 is fixed on one arc-shaped panel 30, and the other end of the elastic insert 31 is slidably inserted into another arc-shaped panel 30.

[0061] An extension plate 32 is provided on the arc-shaped panel 30. The extension plate 32 is slidably mounted on the buckle plate 27, and the sliding direction of the extension plate 32 is along the radial direction of the buckle plate 27. An adjustment plate 33 is rotatably provided in the middle of the buckle plate 27. The adjustment plate 33 is connected to each extension plate 32 through an adjustment arm 34, and the adjustment plate 33 is fixed to the buckle plate 27 by a lock nut.

[0062] In detail, the elastic insert 31 can realize the transition connection between two arc-shaped splice plates 30, and as the extension plate 32 slides on the buckle plate 27, the elastic insert 31 can undergo a small amount of elastic deformation, so that the circle composed of multiple arc-shaped splice plates 30 and multiple elastic insert plates 31 remains intact, making it easy to move smoothly on the slope. When it is necessary to adjust the depth of the trench dug by the plow blade 4, the locking nut on the adjustment plate 33 can be loosened and the adjustment plate 33 can be rotated. At this time, the adjustment plate 33 will drive the extension plate 32 to move through the adjustment arm 34, thereby adjusting the position of the arc-shaped splice plates 30, which makes it convenient to adjust the diameter of the circle composed of multiple arc-shaped splice plates 30 and multiple elastic insert plates 31.

[0063] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
