Description

Technical Field

[0001] This application relates to the technical field of ecological restoration equipment, and particularly to an ecological restoration device for the slopes of abandoned mines. Background Art

[0002] Mineral resources play an important role in economic development. With the development of mineral resource exploitation technology, the exploitation speed of mineral resources is getting faster and faster, and more and more abandoned mines have been left behind.

[0003] In order to restore the ecological environment of abandoned mines, it is necessary to first level the gangue and waste residues of the abandoned mines, then landfill them, introduce imported soil, and finally plant trees and vegetation on the surface to improve the soil environment. After a period of restoration, economic crops can be planted, so as to re-green and utilize the abandoned mining area.

[0004] Due to the large slope of the slope area of the abandoned mine after trimming, when planting vegetation, mechanized farming tools cannot work stably, and there are risks such as tipping over. Manual planting has a large workload and takes a long time, resulting in a low ecological restoration efficiency in the slope area of the abandoned mine. Summary of the Invention

[0005] In order to improve the vegetation planting speed in the slope area of the abandoned mine, and thus improve the ecological restoration efficiency in the slope area of the abandoned mine, this application provides an ecological restoration device for the slopes of abandoned mines.

[0006] An ecological restoration device for the slopes of abandoned mines provided by this application adopts the following technical solutions:

[0007] An ecological restoration device for the slopes of abandoned mines includes a vehicle body, a spraying assembly, a driving assembly, and an adjusting assembly; a soil storage tank, a seed storage tank, and a mixing tank are fixedly arranged on the vehicle body; a first conveying pipe is communicated between the soil storage tank and the mixing tank; a second conveying pipe is communicated between the seed storage tank and the mixing tank; conveying pumps are installed on both the first conveying pipe and the second conveying pipe; the spraying assembly includes a spray head, a first discharge pipe, and a second discharge pipe; the spray head is rotatably arranged on the vehicle body; the first discharge pipe is fixedly arranged on the spray head, and the first discharge pipe is communicated with the mixing tank; the second discharge pipe is communicated with the soil storage tank, and pressurized conveying pumps are installed on both the first discharge pipe and the second discharge pipe; a first branch pipe and a second branch pipe are communicated on the second discharge pipe, the first branch pipe and the second branch pipe are both fixedly arranged on the spray head, and the first branch pipe and the second branch pipe are respectively located on the upper and lower sides of the first discharge pipe; the driving assembly is arranged on the vehicle body and is used to drive the spray head to rotate reciprocally in the vertical plane during the movement of the vehicle body; the adjusting assembly is arranged on the vehicle body and is used to adjust the communication state of the first branch pipe and the second branch pipe.

[0008] By adopting the above technical solution, when carrying out ecological restoration on the slope of a disused mine, the operator pours the imported soil and grass seeds into the soil storage box and the seed storage box, starts the delivery pump, so that both the imported soil and the grass seeds enter the mixing box. Then the operator starts the pressurized delivery pump and makes the vehicle body travel beside the slope of the disused mine to be restored. During the traveling process, the spray head is driven by the driving component to rotate up and down reciprocally in the vertical plane, and the communication state of the first branch pipe and the second branch pipe is adjusted by the adjusting component.

[0009] When the spray head rotates upward, the adjusting component makes the first branch pipe communicate, and the imported soil is sprayed from the second discharge pipe and the first branch pipe onto the slope to be restored. The mixture of grass seeds and imported soil in the mixing box is sprayed onto the slope to be restored through the first discharge pipe. Since the first branch pipe is located above the second discharge pipe, the imported soil in the first branch pipe first covers the slope to be restored, and then the mixture of imported soil and grass seeds sprayed from the first discharge pipe covers the slope to be restored.

[0010] When the spray head rotates downward, the adjusting component makes the second branch pipe communicate, and the imported soil is sprayed from the second discharge pipe and the second branch pipe onto the slope to be restored. The mixture of grass seeds and imported soil in the mixing box is sprayed onto the slope to be restored through the first discharge pipe. Since the second branch pipe is located below the second discharge pipe, the imported soil in the second branch pipe first covers the slope to be restored, and then the mixture of imported soil and grass seeds sprayed from the first discharge pipe covers the slope to be restored.

[0011] As the vehicle body travels, the imported soil, grass seeds and the mixture of imported soil and grass seeds sprayed from the spray head cover the slope of the disused mine along a wavy track. After waiting for a period of time, the slope of the disused mine is covered with vegetation, and the ecological restoration is completed. It only needs to make the vehicle body travel on the flat ground beside the disused slope, and there is no need to drive onto the slope body to carry out vegetation planting. There is no risk of rollover. Moreover, by first spraying and covering the imported soil and then spraying and covering the mixture of imported soil and grass seeds, not only the seeding speed is fast and the efficiency is high, but also the survival rate of grass seeds can be guaranteed, improving the efficiency of ecological restoration in the area of the slope of the disused mine.

[0012] Optionally, the driving component includes a fixed rod, a crank, a connecting rod and a transmission component; the fixed rod is fixedly arranged on the vehicle body, and the spray head is rotatably connected to the fixed rod; the crank is rotatably connected to the fixed rod; both ends of the connecting rod are respectively hinged to the crank and the spray head; the connecting rod, the fixed rod, the crank and the spray head together form a crank-rocker mechanism, where the crank is the shortest rod and the fixed rod is the frame; the transmission component is arranged on the vehicle body and is used to transmit the power provided by the traveling of the vehicle body to the crank and drive the crank to rotate.

[0013] By adopting the above technical solution, the power provided by the movement of the vehicle body is transmitted to the crank through the transmission component, and then the sprinkler head is driven to rotate through the crank-rocker mechanism. Not only is there no need to additionally install a driving component, but also the movement of the vehicle body is linked to the rotation of the sprinkler head, ensuring that the soil and grass seeds can cover the slope of the abandoned mine in a wavy trajectory, thus avoiding omission.

[0014] Optionally, the transmission component includes a first bevel gear and a second bevel gear; the first bevel gear is coaxially and fixedly connected to the wheel of the vehicle body; the second bevel gear is rotatably connected to the vehicle body and fixedly connected to the crank, and the second bevel gear meshes with the first bevel gear.

[0015] By adopting the above technical solution, when the vehicle body moves, the wheel rotates, driving the first bevel gear to rotate, so that the second bevel gear drives the crank to rotate, realizing the transmission of the power provided by the movement of the vehicle body to the crank and driving the crank to rotate.

[0016] Optionally, the adjustment component includes a rotating plate, a servo motor and a control component; the rotating plate is rotatably arranged in the second discharge pipe and is located at the connection of the second discharge pipe with the first branch pipe and the second branch pipe; the servo motor is fixedly arranged on the second discharge pipe, and the servo motor is used to drive the rotating plate to rotate; the control component is arranged on the vehicle body and is used to control the working state of the servo motor according to the rotation state of the sprinkler head.

[0017] By adopting the above technical solution, during the ecological restoration process of the slope of the abandoned mine, when the sprinkler head rotates upward to the limit position, the control component controls the servo motor to work, driving the rotating plate to rotate, so that the second branch pipe is connected, and at this time the sprinkler head starts to rotate downward. When the sprinkler head rotates downward to the limit position, the control component controls the servo motor to work, driving the rotating plate to rotate in the reverse direction, so that the first branch pipe is connected, and at this time the sprinkler head starts to rotate upward, thus realizing the adjustment of the connection state of the first branch pipe and the second branch pipe according to the rotation position of the sprinkler head.

[0018] Optionally, the control component includes a touch switch and a controller; there are two touch switches, which are respectively located at the two limit positions of the rotation of the sprinkler head. One touch switch is connected to the mixing tank, and the other touch switch is connected to the vehicle body; the controller is fixedly arranged on the vehicle body, and the controller is electrically connected to the touch switch and the servo motor, and the controller is used to receive the signal input by the touch switch and control the working state of the servo motor.

[0019] By adopting the above technical solution, when the spray head rotates to the upper and lower extreme positions, the touch switches located above and below the spray head are triggered respectively. The touch switches send signals to the controller, and the controller controls the servo motor to work, thereby driving the rotating plate to rotate.

[0020] Optionally, the first discharge pipe is a flexible pipe; one ends of the second discharge pipe, the first branch pipe, and the second branch pipe are hard pipes; the connections between the first branch pipe and the second branch pipe and the spray head are flexible pipes.

[0022] Optionally, a stirring assembly is provided on the mixing box. The stirring assembly includes a motor and stirring rods; the motor is fixedly arranged on the mixing box; several stirring rods are provided and are all fixedly connected to the output shaft of the motor.

[0023] By adopting the above technical solution, when the soil and grass seeds are conveyed into the mixing box, the motor is in a working state. The motor drives the stirring rods to rotate, stirring the soil and grass seeds, so that the grass seeds are evenly mixed into the soil, thereby ensuring uniform coverage of the vegetation.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] By setting up the spraying assembly, the driving assembly and the adjusting assembly, as the vehicle body moves forward, the mixture of the soil and grass seeds and the soil sprayed from the spray head covers the slope of the abandoned mine along a wavy trajectory. After waiting for a period of time, the slope of the abandoned mine is covered with vegetation, and the ecological restoration is completed. It only needs to make the vehicle body move forward on the flat ground beside the abandoned slope, without having to drive onto the slope body, so that vegetation can be planted without the risk of rollover. Moreover, by first spraying and covering the soil and then spraying and covering the mixture of the soil and grass seeds, not only the seeding speed is fast and the efficiency is high, but also the survival rate of the grass seeds can be guaranteed, improving the efficiency of ecological restoration in the area of the slope of the abandoned mine;

[0026] By setting up the transmission components, the power provided by the forward movement of the vehicle body is transmitted to the crank, and then the crank-rocker mechanism is used to drive the spray head to rotate.

[0027] By setting up the stirring assembly, when the soil and grass seeds are conveyed into the mixing box, the motor is in a working state.

[0040] An embodiment of the present application discloses an ecological restoration device for waste mine slopes. Referring to Figure 1 , an ecological restoration device for waste mine slopes includes a vehicle body 1, a spraying assembly 2, a driving assembly 3, and an adjusting assembly 4. A driving member is provided on the vehicle body 1, and the driving member is used to drive the vehicle body 1 to move forward. The driving member is a motor fixedly arranged on the vehicle body 1. There is at least one motor, and the output shaft of the motor is coaxially and fixedly connected to the wheels on the vehicle body 1.

[0041] Referring to Figure 1 and Figure 2, a soil storage box 11, a seed storage box 12, and a mixing box 13 are fixedly arranged on the vehicle body 1. The soil storage box 11 is used to place the imported soil. The imported soil is preferably the soil with a good ecological environment closest to the abandoned mine, and water is added to form a mud-like state. When necessary, nutrient solution is added to the imported soil. The seed storage box 12 is used to place grass seeds. The grass seeds are preferably transplanted from nearby varieties that are easy to grow and survive. Feeding pipes are connected and arranged at the tops of both the soil storage box 11 and the seed storage box 12. The mixing box 13 is located between the soil storage box 11 and the seed storage box 12. A first conveying pipe 111 is connected to the soil storage box 11, and the other end of the first conveying pipe 111 is connected to the inside of the mixing box 13. A second conveying pipe 121 is connected to the seed storage box 12, and the other end of the second conveying pipe 121 is also connected to the inside of the mixing box 13. Conveying pumps are fixedly installed on both the first conveying pipe 111 and the second conveying pipe 121.

[0042] Referring to Figure 1 and Figure 3 , the spraying assembly 2 includes a spray head 21, a first discharge pipe 22, and a second discharge pipe 23. The spray head 21 is arranged on the vehicle body 1. One end of the first discharge pipe 22 is fixedly penetrated through the spray head 21, and the other end is connected to the inside of the mixing box 13. The first discharge pipe 22 is a flexible pipe. One end of the second discharge pipe 23 is connected to the inside of the soil storage box 11. Pressurized conveying pumps are fixedly installed on both the first discharge pipe 22 and the second discharge pipe 23. A first branch pipe 231 and a second branch pipe 232 are connected and arranged at the end of the second discharge pipe 23 far from the soil storage box 11. The first branch pipe 231 and the second branch pipe 232 are fixedly penetrated through the spray head 21 and are respectively located on the upper and lower sides of the first discharge pipe 22. In other words, the first branch pipe 231, the first discharge pipe 22, and the second branch pipe 232 are arranged in a vertically downward direction. The ends of the first branch pipe 231 and the second branch pipe 232 close to the spray head 21 are flexible pipes, and the ends far from the spray head 21 are rigid pipes.

[0043] The driving assembly 3 is arranged on the vehicle body 1 and is used to drive the spray head 21 to reciprocally rotate in a vertical plane during the traveling process of the vehicle body 1. The adjusting assembly 4 is arranged on the vehicle body 1 and is used to adjust the connection state of the first branch pipe 231 and the second branch pipe 232.

[0044] When carrying out ecological restoration on the slope of the abandoned mine, the operator puts the imported soil and grass seeds into the soil storage box 11 and the seed storage box 12 respectively through the feeding pipes, and then starts the conveying pumps to enable the imported soil and grass seeds to enter the mixing box 13 through the first conveying pipe 111 and the second conveying pipe 121 respectively. Then the operator starts the pressurized conveying pumps on the first discharge pipe 22 and the second discharge pipe 23, and makes the vehicle body 1 travel at a constant speed beside the slope of the abandoned mine to be restored. During the traveling process, the driving assembly 3 drives the spray head 21 to reciprocally rotate up and down in a vertical plane, and the adjusting assembly 4 adjusts the connection state of the first branch pipe 231 and the second branch pipe 232.

[0045] When the nozzle 21 rotates upward, the first branch pipe 231 is connected. Under the action of the pressure conveying pump, the filling soil in the soil storage box 11 is sprayed out through the second discharge pipe 23, and then sprayed out through the first branch pipe 231 onto the slope to be repaired. The mixture of grass seeds and filling soil in the mixing box 13 is sprayed out through the first discharge pipe 22 onto the slope to be repaired. Since the first branch pipe 231 is located above the second discharge pipe 23, when the nozzle 21 rotates upward, the filling soil in the first branch pipe 231 first covers the slope to be repaired, and then the mixture of filling soil and grass seeds sprayed out from the first discharge pipe 22 covers the slope to be repaired.

[0046] When the nozzle 21 rotates downward, the second branch pipe 232 is connected. Under the action of the pressure conveying pump, the filling soil in the soil storage box 11 is sprayed out through the second discharge pipe 23, and then sprayed out through the second branch pipe 232 onto the slope to be repaired. Since the second branch pipe 232 is located below the second discharge pipe 23, when the nozzle 21 rotates downward, the filling soil in the second branch pipe 232 first covers the slope to be repaired, and then the mixture of filling soil and grass seeds sprayed out from the first discharge pipe 22 covers the slope to be repaired. As the vehicle body 1 moves forward, the filling soil, grass seeds, and the mixture of filling soil sprayed out from the nozzle 21 cover the slope of the abandoned mine along a wavy trajectory. After waiting for a period of time, the slope of the abandoned mine is covered with vegetation, and the ecological restoration is completed.

[0047] Refer to Figure 2 and Figure 4 Referring to

[0048] Refer to Figure 2, the transmission component 34 includes a first bevel gear 341 and a second bevel gear 342. The first bevel gear 341 is coaxially and fixedly connected to the non-driving wheel of the vehicle body 1. The second bevel gear 342 is rotatably connected to the vehicle body 1, and the rotation axis is coaxially arranged with the rotation axis of the crank 32 and the fixed rod 31. The second bevel gear 342 is fixedly connected to the crank 32 through a rotating shaft, and the second bevel gear 342 meshes with the first bevel gear 341. In some other embodiments, a gear reduction box is directly connected to the second bevel gear 342 and the crank 32 for adjusting the transmission ratio between the second bevel gear 342 and the crank 32.

[0049] When ecological restoration is carried out on the slope of the abandoned mine, when the vehicle body 1 moves forward, the wheels rotate, driving the first bevel gear 341 to rotate, so that the second bevel gear 342 drives the crank 32 to rotate. The crank 32 drives the spray head 21 to reciprocally rotate around its rotation axis with the fixed rod 31 through the connecting rod 33, thereby realizing driving the spray head 21 to reciprocally rotate in the vertical plane during the forward movement of the vehicle body 1.

[0050] Refer to Figure 3 and Figure 5 , the adjusting component 4 includes a rotating plate 41, a servo motor 42 and a control component 43. The rotating plate 41 is rotatably arranged in the second discharge pipe 23 and is located at the connection of the second discharge pipe 23 with the first branch pipe 231 and the second branch pipe 232. The servo motor 42 is fixedly arranged on the second discharge pipe 23. The output shaft of the servo motor 42 penetrates through the side wall of the second discharge pipe 23 and is fixedly connected to the rotating plate 41.

[0051] Refer to Figure 1 and Figure 4 , the control component 43 includes a touch switch 431 and a controller 432. There are two touch switches 431, which are respectively located at two limit positions of the rotation of the spray head 21. One touch switch 431 is fixedly connected to the mixing tank 13, and the other touch switch 431 is fixedly connected to the bottom plate of the vehicle body 1. The controller 432 is fixedly arranged on the vehicle body 1. The controller 432 is electrically connected to both the servo motor 42 and the touch switch 431. The controller 432 is used to receive the signals input by the touch switch 431 and control the working state of the servo motor 42.

[0052] During the ecological restoration process of the abandoned mine slope, when the spray head 21 rotates upward to the limit position, the touch switch 431 located above the spray head 21 is triggered, and the controller 432 controls the servo motor 42 to work, driving the rotating plate 41 to rotate, so that the second branch pipe 232 is connected, and at this time the spray head 21 rotates downward. When the spray head 21 rotates downward to the limit position, the touch switch 431 located below the spray head 21 is triggered, and the controller 432 controls the servo motor 42 to work, driving the rotating plate 41 to rotate in the opposite direction, so that the first branch pipe 231 is connected, and at this time the spray head 21 rotates upward.

[0053] Referring to Figure 2 and Figure 4 A stirring assembly 5 is provided on the mixing tank 13. The stirring assembly 5 includes a motor 51 and stirring rods 52. The motor 51 is fixedly arranged on the top of the mixing tank 13. A plurality of stirring rods 52 are provided and are located inside the mixing tank 13. The stirring rods 52 are fixedly connected to the output shaft of the motor 51 through rotating shafts.

[0054] When the soil and grass seeds are conveyed into the interior of the mixing tank 13, the motor 51 is in a working state. The motor 51 drives the stirring rods 52 to rotate, stirring the soil and grass seeds, so that the grass seeds are evenly mixed into the soil.

[0055] The implementation principle of the ecological restoration device for the slope of abandoned mines in the embodiment of the present application is as follows:

[0056] When carrying out ecological restoration on the slope of an abandoned mine, the operator puts the soil and grass seeds into the soil storage tank 11 and the seed storage tank 12 respectively, and then starts the delivery pump, so that the soil and grass seeds enter the mixing tank 13 through the first delivery pipe 111 and the second delivery pipe 121 respectively. The motor 51 is in a working state. The motor 51 drives the stirring rods 52 to rotate, stirring the soil and grass seeds, so that the grass seeds are evenly mixed into the soil.

[0057] Then the operator starts the pressurized delivery pumps on the first discharge pipe 22 and the second discharge pipe 23, and makes the vehicle body 1 travel at a constant speed beside the slope to be repaired of the abandoned mine. The wheels rotate, driving the first bevel gear 341 to rotate, so that the second bevel gear 342 drives the crank 32 to rotate. The crank 32 drives the spray head 21 to reciprocate up and down around its rotation axis with the fixed rod 31 through the connecting rod 33.

[0058] When the spray head 21 rotates upward to the limit position, the touch switch 431 above the spray head 21 is triggered. The controller 432 controls the servo motor 42 to work, driving the rotating plate 41 to rotate, so that the second branch pipe 232 is communicated. At this time, the spray head 21 rotates downward. Under the action of the pressurized delivery pump, the soil in the soil storage tank 11 is sprayed out through the second discharge pipe 23, and then is sprayed out through the second branch pipe 232 onto the slope to be repaired. Since the second branch pipe 232 is located below the second discharge pipe 23, when the spray head 21 rotates downward, the soil from the second branch pipe 232 first covers the slope to be repaired, and then the mixture of soil and grass seeds sprayed out from the first discharge pipe 22 covers the slope to be repaired.

[0059] When the nozzle 21 rotates downward to the extreme position, the touch switch 431 located below the nozzle 21 is triggered, and the controller 432 controls the servo 42 to operate, driving the rotating plate 41 to rotate in the opposite direction, enabling the first branch pipe 231 to communicate. At this time, the nozzle 21 rotates upward. Under the action of the pressurized delivery pump, the soil in the soil storage tank 11 is sprayed out through the second discharge pipe 23, and then through the first branch pipe 231 to the slope to be repaired. The mixture of grass seeds and soil in the mixing tank 13 is sprayed out through the first discharge pipe 22 to the slope to be repaired. Since the first branch pipe 231 is above the second discharge pipe 23, when the nozzle 21 rotates upward, the soil in the first branch pipe 231 first covers the slope to be repaired, and then the mixture of soil and grass seeds sprayed out from the first discharge pipe 22 covers the slope to be repaired again.

[0060] As the vehicle body 1 moves forward, the soil and the mixture of grass seeds and soil sprayed out from the nozzle 21 cover the slope of the abandoned mine along a wavy trajectory. After waiting for a period of time, the slope of the abandoned mine is covered with vegetation, and the ecological restoration is completed.

[0061] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
