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

[0003] In order to restore the ecological environment of abandoned mines, it is necessary to first level the gangue and slag of the abandoned mines, then fill them, introduce foreign 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, thus re-greening the abandoned mining area.

[0004] Due to the steep slope of the abandoned mine slope after repair, mechanized farming tools cannot work smoothly when planting vegetation, and there is a risk of rollover. Manual planting is labor-intensive and time-consuming, resulting in low efficiency of ecological restoration in the abandoned mine slope area. Summary of the invention

[0005] In order to increase the vegetation planting speed in abandoned mine slope areas, thereby improving the ecological restoration efficiency of abandoned mine slope areas, the present application provides an abandoned mine slope ecological restoration device.

[0006] The present application provides an abandoned mine slope ecological restoration device, which adopts the following technical solution: An abandoned mine slope ecological restoration device comprises a vehicle body, a spraying assembly, a driving assembly and an adjusting assembly; a soil storage box, a seed storage box and a mixing box are fixedly arranged on the vehicle body; a first conveying pipe is arranged in communication between the soil storage box and the mixing box; a second conveying pipe is arranged in communication between the seed storage box and the mixing box; a conveying pump is installed on both the first conveying pipe and the second conveying pipe; the spraying assembly comprises a nozzle, a first discharge pipe and a second discharge pipe; the nozzle is rotatably arranged on the vehicle body; the first discharge pipe is fixedly arranged on the nozzle, and the first discharge pipe is communicated with the mixing box; the first Two discharge pipes are connected to the soil storage box, and a pressurized delivery pump is installed on the first discharge pipe and the second discharge pipe; the second discharge pipe is connected to a first branch pipe and a second branch pipe, and the first branch pipe and the second branch pipe are fixedly arranged on the nozzle, 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 nozzle to reciprocate in a vertical plane during the movement of the vehicle body; the adjusting assembly is arranged on the vehicle body, and is used to adjust the connection state of the first branch pipe and the second branch pipe.

[0007] By adopting the above technical solution, when ecological restoration is carried out on the slope of abandoned mines, the operator pours the foreign soil and grass seeds into the soil storage box and the seed storage box, starts the delivery pump, and allows the foreign soil and grass seeds to enter the mixing box. Then the operator starts the pressurized delivery pump and moves the vehicle body beside the slope to be restored in the abandoned mine. During the movement, the driving component drives the nozzle to reciprocate up and down in the vertical plane, and the adjustment component adjusts the connection state of the first branch pipe and the second branch pipe.

[0008] When the nozzle rotates upward, the adjustment component connects the first branch pipe, and the guest soil is sprayed from the second discharge pipe and the first branch pipe onto the slope to be repaired. The mixture of grass seeds and guest soil in the mixing box is sprayed through the first discharge pipe onto the slope to be repaired. Since the first branch pipe is located above the second discharge pipe, the guest soil in the first branch pipe first covers the slope to be repaired, and then the mixture of guest soil and grass seeds sprayed from the first discharge pipe covers the slope to be repaired.

[0009] When the nozzle rotates downward, the adjustment component connects the second branch pipe, and the guest soil is sprayed from the second discharge pipe and the second branch pipe to the slope to be repaired.

When the nozzle rotates downward to the extreme position, the control component controls the steering gear to drive the rotating plate to rotate in the opposite direction so that the first branch pipe is connected, and the nozzle starts to rotate upward, thereby realizing the adjustment of the connection state of the first branch pipe and the second branch pipe according to the rotation position of the nozzle.

[0027] The present application embodiment discloses an abandoned mine slope ecological restoration device. Figure 1 An abandoned mine slope ecological restoration device comprises a vehicle body 1, a spraying assembly 2, a driving assembly 3 and an adjusting assembly 4. The vehicle body 1 is provided with a driving member, which is used to drive the vehicle body 1 to move forward.

The soil storage box 11 is used to place foreign soil. It is best to use soil with a good ecological environment closest to the abandoned mine, and add water to form mud. If necessary, nutrient solution is added to the foreign soil. The seed storage box 12 is used to place grass seeds. It is best to transplant grass seeds from nearby varieties that are easy to grow and survive. Feed pipes are connected to the tops of 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 the first conveying pipe 111 and the second conveying pipe 121.

[0029] Reference Figure 1 and Figure 3 The spray assembly 2 includes a nozzle 21, a first discharge pipe 22 and a second discharge pipe 23. The nozzle 21 is arranged on the vehicle body 1. One end of the first discharge pipe 22 is fixedly penetrated on the nozzle 21, and the other end is connected to the inside of the mixing box 13. The first discharge pipe 22 adopts a hose. One end of the second discharge pipe 23 is connected to the inside of the soil storage box 11. A pressurized delivery pump is fixedly installed on the first discharge pipe 22 and the second discharge pipe 23. The end of the second discharge pipe 23 away from the soil storage box 11 is connected with a first branch pipe 231 and a second branch pipe 232. The first branch pipe 231 and the second branch pipe 232 are fixedly penetrated on the nozzle 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 vertical downward direction. The ends of the first branch pipe 231 and the second branch pipe 232 close to the nozzle 21 adopt a hose, and the ends away from the nozzle 21 adopt a hard pipe.

[0030] The driving assembly 3 is disposed on the vehicle body 1 and is used to drive the spray head 21 to reciprocate in a vertical plane during the movement of the vehicle body 1. The adjusting assembly 4 is disposed on the vehicle body 1 and is used to adjust the connection state between the first branch pipe 231 and the second branch pipe 232.

[0031] When ecological restoration is performed on the slope of an abandoned mine, the operator puts the foreign soil and grass seeds into the soil storage box 11 and the seed storage box 12 through the feed pipe, and then starts the delivery pump, so that the foreign soil and grass seeds enter the mixing box 13 through the first delivery pipe 111 and the second delivery pipe 121. 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 move at a uniform speed beside the slope to be restored in the abandoned mine. During the movement, the nozzle 21 is driven to reciprocate up and down in the vertical plane through the driving component 3, and the connection state of the first branch pipe 231 and the second branch pipe 232 is adjusted through the adjustment component 4.

[0032] When the nozzle 21 rotates upward, the first branch pipe 231 is connected, and under the action of the pressurized delivery pump, the foreign 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 to the slope to be repaired, and the mixture of grass seeds and foreign soil in the mixing box 13 is sprayed out through the first discharge pipe 22 to 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 foreign soil in the first branch pipe 231 first covers the slope to be repaired, and then the mixture of foreign soil and grass seeds sprayed from the first discharge pipe 22 covers the slope to be repaired.

[0033] When the nozzle 21 rotates downward, the second branch pipe 232 is connected, and under the action of the pressurized delivery pump, the guest soil in the soil storage box 11 is sprayed out through the second discharge pipe 23, and then sprayed out to the slope to be repaired through the second branch pipe 232. Since the second branch pipe 232 is located below the second discharge pipe 23, when the nozzle 21 rotates downward, the guest soil in the second branch pipe 232 first covers the slope to be repaired, and then the mixture of guest soil and grass seeds sprayed from the first discharge pipe 22 covers the slope to be repaired. As the vehicle body 1 moves forward, the guest soil, grass seeds and guest soil mixture sprayed from the nozzle 21 covers the abandoned mine slope along a wavy trajectory. After waiting for a period of time, the abandoned mine slope is covered with vegetation, and the ecological restoration is completed.

[0034] Reference Figure 2 and Figure 4 The driving assembly 3 includes a fixed rod 31, a crank 32, a connecting rod 33 and a transmission component 34. The fixed rod 31 is vertically penetrated on the bottom plate of the vehicle body 1 and is fixedly connected to the vehicle body 1. The nozzle 21 is rotatably connected to the top of the fixed rod 31, and the rotation axis is horizontally set. The crank 32 is rotatably connected to the bottom of the fixed rod 31, and the rotation axis is horizontally set. A connecting groove is opened on the bottom plate of the vehicle body 1. The connecting rod 33 is penetrated in the connecting groove, and the two ends of the connecting rod 33 are respectively hinged to the crank 32 and the nozzle 21, and the hinge axes are both horizontally set. The connecting rod 33, the fixed rod 31, the crank 32 and the nozzle 21 together constitute a crank rocker mechanism. The length of the fixed rod 31, the length of the connecting rod 33, and the distance between the hinge axis of the nozzle 21 and the fixed rod 31 and the hinge axis of the nozzle 21 and the connecting rod 33 are all greater than the length of the crank 32. In other words, the crank 32 is the shortest rod, and the connecting rod 33 is the longest rod. The sum of the lengths of the crank 32 and the connecting rod 33 is less than or equal to the sum of the length of the fixed rod 31 and the distance between the hinge axis of the nozzle 21 and the fixed rod 31 and the hinge axis of the nozzle 21 and the connecting rod 33.

[0035] Reference Figure 2The transmission component 34 includes a first bevel gear 341 and a second bevel gear 342. The first bevel gear 341 is coaxially fixedly connected to the non-driving wheel of the vehicle body 1. The second bevel gear 342 is rotationally 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 via a rotating shaft, and the second bevel gear 342 is meshed with the first bevel gear 341. In some other embodiments, the second bevel gear 342 and the crank 32 are directly connected to a gear reduction box for adjusting the transmission ratio between the second bevel gear 342 and the crank 32.

[0036] When ecological restoration is carried out on the slopes of abandoned mines, when the vehicle body 1 moves, the wheels rotate, driving the first bevel gear 341 to rotate, so that the second bevel gear 342 drives the crank 32 to rotate, and the crank 32 drives the nozzle 21 to reciprocate around the rotation axis between itself and the fixed rod 31 through the connecting rod 33, thereby realizing the reciprocating rotation of the nozzle 21 in the vertical plane during the movement of the vehicle body 1.

[0037] Reference Figure 3 and Figure 5 The adjustment assembly 4 includes a rotating plate 41, a steering gear 42 and a control component 43. The rotating plate 41 is rotatably disposed in the second discharge pipe 23 and is located at the connection between the second discharge pipe 23 and the first branch pipe 231 and the second branch pipe 232. The steering gear 42 is fixedly disposed on the second discharge pipe 23, and the output shaft of the steering gear 42 is penetrated on the side wall of the second discharge pipe 23 and is fixedly connected to the rotating plate 41.

[0038] Reference Figure 1 and Figure 4 The control component 43 includes a touch switch 431 and a controller 432. Two touch switches 431 are provided, and are respectively located at two extreme positions of the rotation of the nozzle 21. One of the touch switches 431 is fixedly connected to the mixing box 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, and the controller 432 is electrically connected to the steering gear 42 and the touch switch 431. The controller 432 is used to receive the signal input by the touch switch 431 and control the working state of the steering gear 42.

[0039] During the ecological restoration of the abandoned mine slope, when the nozzle 21 rotates upward to the extreme position, the touch switch 431 located above the nozzle 21 is triggered, and the controller 432 controls the steering gear 42 to work, driving the rotating plate 41 to rotate, so that the second branch pipe 232 is connected, and the nozzle 21 rotates downward. 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 steering gear 42 to work, driving the rotating plate 41 to rotate in the opposite direction, so that the first branch pipe 231 is connected, and the nozzle 21 rotates upward.

[0040] Reference Figure 2 and Figure 4 The mixing box 13 is provided with a stirring assembly 5, which includes a motor 51 and a stirring rod 52. The motor 51 is fixedly arranged on the top of the mixing box 13. A plurality of stirring rods 52 are provided and located in the mixing box 13, and the stirring rods 52 are fixedly connected to the output shaft of the motor 51 through a rotating shaft.

[0041] When the foreign soil and grass seeds are transported into the mixing box 13, the motor 51 is in operation, and the motor 51 drives the stirring rod 52 to rotate, stirring the foreign soil and grass seeds, so that the grass seeds are evenly mixed into the foreign soil.

[0042] The implementation principle of an abandoned mine slope ecological restoration device in the embodiment of the present application is: When ecological restoration is carried out on the slope of an abandoned mine, the operator puts the guest soil and grass seeds into the soil storage box 11 and the seed storage box 12 respectively, and then starts the delivery pump to allow the guest soil and grass seeds to enter the mixing box 13 through the first delivery pipe 111 and the second delivery pipe 121 respectively. The motor 51 is in a working state, and the motor 51 drives the stirring rod 52 to rotate, stirring the guest soil and grass seeds so that the grass seeds are evenly mixed into the guest soil.

[0043] 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 move at a constant speed beside the slope to be repaired in 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, and the crank 32 drives the nozzle 21 to reciprocate up and down around the rotation axis between itself and the fixed rod 31 through the connecting rod 33.

[0044] When the nozzle 21 rotates upward to the limit position, the touch switch 431 located above the nozzle 21 is triggered, and the controller 432 controls the steering gear 42 to work, driving the rotating plate 41 to rotate, so that the second branch pipe 232 is connected, and the nozzle 21 rotates downward. Under the action of the pressurized delivery pump, the foreign 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 to 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 foreign soil in the second branch pipe 232 first covers the slope to be repaired, and then the mixture of foreign soil and grass seeds sprayed from the first discharge pipe 22 covers the slope to be repaired.

[0045] When the nozzle 21 rotates downward to the limit position, the touch switch 431 located below the nozzle 21 is triggered, and the controller 432 controls the steering gear 42 to work, driving the rotating plate 41 to rotate in the opposite direction, so that the first branch pipe 231 is connected, and the nozzle 21 rotates upward. Under the action of the pressurized delivery pump, the foreign 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 to the slope to be repaired, and the mixture of grass seeds and foreign soil in the mixing box 13 is sprayed out through the first discharge pipe 22 to 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 foreign soil in the first branch pipe 231 first covers the slope to be repaired, and then the mixture of foreign soil and grass seeds sprayed from the first discharge pipe 22 covers the slope to be repaired.

[0046] As the vehicle body 1 moves forward, the foreign soil and the mixture of grass seeds and foreign soil sprayed from the nozzle 21 cover the abandoned mine slope along a wavy trajectory. After waiting for a period of time, the abandoned mine slope is covered with vegetation, and the ecological restoration is completed.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
