[0001] The present invention belongs to the field related to mine restoration, and more specifically relates to a crushed stone processing device for mine restoration. Background Art

[0002] Mining activities have long faced the dual challenges of overexploitation of resources and ecological damage. The large amounts of waste rock, tailings, and broken rock produced during open-pit mining or underground tunneling not only consume land resources but can also cause soil erosion and the spread of heavy metal pollution due to rainwater, seriously threatening the safety of surrounding ecosystems. Traditional disposal methods, often based on simple stockpiling, are inefficient and prone to secondary pollution, making them inadequate for the green transformation of modern mines and ecological restoration.

[0003] The application document with publication number CN111686845A records a screenable mine gravel processing device, wherein a feed port is opened at one end of the feed box, and an extrusion mechanism is connected to the bottom end of the feed box by bolts.

The bottom end of the feed box is connected to the extrusion box by bolts. The structure is scientific and reasonable, and it is safe and convenient to use. An extrusion mechanism is provided, and the stone is crushed in the first step through the extrusion box. The elliptical rotating rod is driven to rotate by the first rotating motor, and the movable splint is continuously pushed to move through the push plate.

[0004] The above-mentioned processing device has certain deficiencies when performing ore gravel processing operations. The above-mentioned device is mainly used to crush mine gravel, and its functionality is single. The mine gravel still needs to be manually retrieved and sorted when crushed. A large amount of ore gravel increases the time required for its retrieval and sorting, and it does not have a gravel recovery function; secondly, the crushed gravel cannot be directly utilized after the crushing process, and its functionality is single. It does not have an extended auxiliary function and cannot be directly utilized after the crushing process is completed; at the same time, when crushing mine gravel, gravel of different sizes is prone to jamming, and it cannot be adjusted arbitrarily according to the coarseness of the crushed stone, and the functionality is single. Summary of the Invention

[0005] The purpose of the present invention is to provide a crushed stone processing device for mine restoration, which can solve the existing problems.

[0006] The problems solved by the present invention are:

[0007] 1. Traditional equipment is mainly used to crush mine gravel, and its functionality is single. When crushing mine gravel, it still needs to be manually sorted. A large amount of mine gravel increases the time required for sorting, and it does not have the function of gravel recovery. Secondly, the crushed gravel cannot be directly used. It has a single functionality and does not have an extended auxiliary function. It cannot be directly used after the crushing of the gravel. At the same time, when crushing mine gravel, gravel of different sizes is prone to jamming, and it cannot be adjusted arbitrarily according to the coarseness of the crushed stone. The functionality is single.

[0008] The purpose of the present invention can be achieved through the following technical solutions:

[0009] The loader is a material distribution device for the material distribution unit, and the material distribution device is a material distribution device for the material distribution unit.

[0010] The gear train is connected to the conveyor belt by a gear chain structure, and the conveyor belt is connected to the conveyor belt by a gear train.

[0011] As a further technical solution of the present invention, the lifting rod and the screening box are driven by a hydraulic rod, a crushing box is fixedly installed on the upper end of the screening box, and a discharge hopper is provided at the rear end of the mobile material box. When the mobile material box is full of gravel, the lifting rod is driven by the hydraulic rod to adjust the angle of the lifting rod so that the lifting rod drives the material receiving part to move upward, and the mobile material box is placed above the crushing box. At the same time, the discharge hopper is aligned with the crushing box, so that the gravel is poured into the interior of the crushing box through the discharge hopper, and the gravel is crushed by the crushing box.

[0012] As a further technical solution of the present invention, an inclined screen is fixedly installed inside the screening box, and a partition plate is fixedly installed inside the screening box at the lower part of the inclined screen. The inclined screen and the partition plate are both inclined. A vibrator is provided at the bottom of the inclined screen. When the crushing box completes the crushing process of the gravel, the crushed gravel enters the interior of the screening box, and the inclined screen is driven to vibrate by the vibrator, so that the inclined screen completes the screening process of the gravel. A part of the gravel is retained at the upper end of the inclined screen and discharged to the lower part of the partition plate through the discharger, and the other part of the gravel passes through the inclined screen and is retained on the upper part of the partition plate. The gravel is layered and stored inside the screening box through the partition plate, and the gravel on the upper part of the partition plate is discharged through the distributor and can be used for paving.

[0013] As a further technical solution of the present invention, casters are provided at the bottom of the screening box and the mobile material box. A cockpit is fixedly installed on one side of the screening box. The casters at the bottom of the screening box are driven by a motor, so that the screening box can drive the material receiving piece to move its position, and the casters at the bottom of the mobile material box can reduce the friction during its movement.

[0014] As a further technical solution of the present invention, a feed roller is movably installed inside the material guide box, and one end of the feed roller is driven by an electric motor. The motor drives the feed roller to rotate. When the gravel on the upper part of the partition plate enters the interior of the material guide box, the gravel is quantitatively discharged into the interior of the distribution box through the feed roller.

[0015] As a further technical solution of the present invention, vertical partitions and guide plates are fixedly installed inside the material distribution box, and the guide plates are fixedly installed at the lower ends of the vertical partitions. The number of vertical partitions and guide plates is several groups, and the several groups of guide plates are symmetrically arranged in an eight-shaped shape. When the gravel enters the interior of the material distribution box, the vertical partitions are used to divide the gravel into several parts, and the guide plates symmetrically arranged in an eight-shaped shape are used to guide and transport the gravel, so that the gravel is evenly laid on the ground.

[0016] As a further technical solution of the present invention, several groups of material-discharging plates are arranged at the lower end of the material guide plate inside the material distribution box, and the several groups of material-discharging plates are distributed at equal vertical intervals. The arrangement of the material-discharging plates can allow the gravel to pass through the material-discharging plates when the gravel is discharged, and the accumulated gravel can be discharged evenly.

[0017] As a further technical solution of the present invention, a crushing roller and an adjusting roller are movably installed inside the crushing box, the adjusting roller is movably installed on one side of the crushing roller, and a discharge nozzle is fixedly installed at the lower end of the crushing box. The crushing process of the gravel can be completed by the rotation of the crushing roller and the adjusting roller, and the crushed gravel is discharged downward through the discharge nozzle.

[0018] As a further technical solution of the present invention, an inclined slider is provided on one side of the adjusting roller, and the adjusting roller and the crushing box are movably connected through the inclined slider. The upper end of the inclined slider is inclined, and the rear end of the inclined slider is provided with a telescopic guide rod and a screw rod. The screw rod and the inclined slider are movably connected. The user rotates the screw rod to make the screw rod drive the inclined slider, and the adjusting roller is driven to move by the inclined slider, thereby adjusting the distance between the adjusting roller and the crushing roller, so that different sizes of gravel can be used between the adjusting roller and the crushing roller. Secondly, the upper end of the inclined slider adopts an inclined structure design, so that the inclined slider has a gravel guiding function, which can guide the gravel between the adjusting roller and the crushing roller.

[0019] Beneficial effects of the present invention:

[0020] 1. By setting up the material receiving part, the crushed stone processing device for mine restoration has an automatic crushed stone recovery structure when it is used, thereby improving the efficiency of mine crushed stone recovery. At the same time, it can complete the preliminary sorting of crushed stone and improve its crushed stone recovery effect;

[0021] During operation, the movable bucket is used in conjunction with the driving wheel installed at the bottom. When the material box is moved forward, one end of the bucket can be adjusted to a corresponding angle according to the undulations of the ground. When cleaning gravel, one end of the bucket can be better in contact with the gravel. Because the gravel is small in size, the traditional bucket structure produces height changes during movement, allowing the gravel to pass through the bottom of the bucket. At the same time, the rotation of the driving wheel during movement drives the feed roller to rotate through the gear set. The feed roller is located at one end of the bucket, so that the feed roller is first in contact with the gravel. When the bucket moves forward, the rotation of the feed roller is used to guide the gravel into the bucket. Inside, the tooth chain structure makes the feed roller drive the conveyor belt, and the conveyor belt is used to transport the crushed stone to the inside of the mobile material box. The mobile material box can carry a part of the crushed stone, so that the bucket does not need to frequently perform side rotation loading operations. The screening rod at the bottom of the mobile material box can be used to screen the mud and sand in the crushed stone. When the mobile material box is full of crushed stone, the hydraulic rod is used to drive the lifting rod to adjust the angle of the lifting rod so that the lifting rod drives the material receiving part to move upward, and the mobile material box is placed above the crushing box. At the same time, the discharge hopper is aligned with the crushing box, so that the crushed stone is poured into the crushing box through the discharge hopper, and the crushed stone is crushed by the crushing box.

[0022] 2. By setting up a distributor and an inclined screen, the gravel processing device for mine restoration can complete the recovery, crushing, screening and paving operations of the gravel respectively, and can quickly convert the crushed gravel into paving stones, quickly solving the problem of mine gravel accumulation;

[0023] The crushed stones are then separated by a feeder and the sieve is fed into the hopper and the hopper is fed into the crushing station, where they are then fed into the hopper which is fed into the hopper and the hopper is fed into the crushing station.

[0024] 3. By setting up the inclined slider, the mine restoration gravel processing device can be used to crush gravels of different sizes, thereby improving its flexibility in use;

[0025] During operation, the user rotates the screw rod to make the screw rod drive the inclined slider, and the inclined slider drives the adjusting roller to move, thereby adjusting the distance between the adjusting roller and the crushing roller. When the gravel passes between the adjusting roller and the crushing roller, the rotation of the adjusting roller and the crushing roller can complete the crushing of the gravel. The adjusting roller and the crushing roller can be driven to rotate by the motor, and the distance between the adjusting roller and the crushing roller can be adjusted to accommodate gravel of different sizes. Secondly, the upper end of the inclined slider adopts an inclined structure design, which makes the inclined slider have a gravel guiding function, which can guide the gravel between the adjusting roller and the crushing roller, and can be adjusted according to the degree of crushing of the gravel. When the distance between the adjusting roller and the crushing roller is larger, the volume of the crushed gravel is larger, and when the distance between the adjusting roller and the crushing roller is smaller, the volume of the crushed gravel is smaller.

A part of the gravel is retained at the upper end of the inclined screen 9 and is discharged to the lower part of the partition plate 19 through the discharger 8, and the other part of the gravel passes through the inclined screen 9 and is retained on the upper part of the partition plate 19. The gravel is layered and stored inside the screening box 7 through the partition plate 19, and the gravel on the upper part of the partition plate 19 is discharged through the distributor 6 and can be used for paving.

[0042] like Figure 4 As shown, casters 20 are provided at the bottom of the screening box 7 and the mobile material box 3, and a cockpit 5 is fixedly installed on one side of the screening box 7. The casters 20 at the bottom of the screening box 7 are driven by a motor, so that the screening box 7 can drive the material receiving piece 1 to move its position, and the casters 20 at the bottom of the mobile material box 3 can reduce the friction during its movement.

[0043] like Figure 5 As shown, a feed roller 22 is movably installed inside the material guide box 23, and one end of the feed roller 22 is driven by a motor 24. The motor 24 drives the feed roller 22 to rotate. When the gravel on the upper part of the partition plate 19 enters the interior of the material guide box 23, the gravel is quantitatively discharged into the interior of the distribution box 21 through the feed roller 22.

[0044] like Figure 6 As shown, vertical partitions 25 and guide plates 26 are fixedly installed inside the material distribution box 21. The guide plates 26 are fixedly installed at the lower ends of the vertical partitions 25. The vertical partitions 25 and guide plates 26 are arranged in several groups, and the several groups of guide plates 26 are symmetrically arranged in an eight-shaped shape. When the gravel enters the interior of the material distribution box 21, the vertical partitions 25 are used to divide the gravel into several parts, and the guide plates 26 symmetrically arranged in an eight-shaped shape are used to guide and transport the gravel, so that the gravel is evenly laid on the ground.

[0045] Inside the material distribution box 21, several groups of material separation plates 32 are arranged at the lower end of the guide plate 26. The several groups of material separation plates 32 are distributed at equal vertical intervals. The arrangement of the material separation plates 32 can allow the gravel to pass through the material separation plates 32 when the gravel is discharged, and the accumulated gravel can be discharged evenly.

[0046] like Figure 7 As shown, a crushing roller 27 and an adjusting roller 28 are movably installed inside the crushing box 10. The adjusting roller 28 is movably installed on one side of the crushing roller 27. A discharge nozzle 29 is fixedly installed at the lower end of the crushing box 10.

The user rotates the screw rod 30 so that the screw rod 30 drives the inclined slider 31, and the adjusting roller 28 is driven to move through the inclined slider 31, thereby adjusting the distance between the adjusting roller 28 and the crushing roller 27, so that different sizes of gravel can be used between the adjusting roller 28 and the crushing roller 27. Secondly, the upper end of the inclined slider 31 adopts an inclined structure design, which makes the inclined slider 31 have a gravel guiding function, and can guide the gravel between the adjusting roller 28 and the crushing roller 27.

[0048] Traditional devices are mainly used to crush mine gravel, and their functionality is single. When crushing mine gravel, it still needs to be manually sorted. A large amount of ore gravel increases the time required for sorting, and it does not have the function of gravel recovery. Secondly, the crushed gravel cannot be directly used after the crushing process. It has a single functionality and no extended auxiliary function. It cannot be used directly after the crushing process. At the same time, when crushing mine gravel, gravel of different sizes is prone to jamming, and it cannot be arbitrarily adjusted according to the coarseness of the crushed stone. The functionality is single.

[0049] To this end, when in use, by setting the material receiving part 1, the crushed stone processing device for mine repair is provided with an automatic crushed stone recovery structure, thereby improving the efficiency of mine crushed stone recovery, and at the same time completing the preliminary sorting of crushed stone, thereby improving its crushed stone recovery effect;

When gravel is being cleaned, one end of the bucket 2 can be better in contact with the gravel. Because the gravel is small in size, the traditional bucket 2 structure produces height changes during movement, so that the gravel passes through the bottom of the bucket 2. At the same time, the rotation of the driving wheel 15 during movement drives the feed roller 13 to rotate through the gear set 17. The feed roller 13 is located at one end of the bucket 2, so that the feed roller 13 first contacts the gravel. When the bucket 2 moves forward, the rotation of the feed roller 13 is used to guide the gravel into the bucket 2, and the gear set 17 is used to move the material. The chain structure enables the feeding roller 13 to drive the conveyor belt 14, and the conveyor belt 14 is used to transport the crushed stones to the interior of the mobile material box 3. The mobile material box 3 can carry a part of the crushed stones, so that the bucket 2 does not need to frequently perform side-rotation loading operations. The screening rod 12 at the bottom of the mobile material box 3 can be used to screen the mud and sand in the crushed stones. When the mobile material box 3 is full of crushed stones, the hydraulic rod 16 is used to drive the lifting rod 4, thereby adjusting the angle of the lifting rod 4, so that the lifting rod 4 drives the material receiving part 1 to move upward, and the mobile material box 3 is placed above the crushing box 10. At the same time, the discharge hopper 18 is aligned with the crushing box 10, so that the crushed stones are poured into the interior of the crushing box 10 through the discharge hopper 18, and the crushed stones are crushed by the crushing box 10;

[0051] By providing the distributor 6 and the inclined screen 9, when the mine repair gravel processing device is used, the recovery, crushing, screening and paving operations of the gravel can be completed respectively, and the crushed gravel can be quickly converted into paving stones, quickly solving the problem of accumulation of mine gravel;

[0052] During use, after the crushing box 10 completes the crushing process of the crushed stones, the crushed stones enter the interior of the screening box 7, and the vibrator drives the inclined screen 9 to vibrate, so that the inclined screen 9 completes the screening process of the crushed stones.

The crushed stones are layered and stored in the interior of the screening box 7 through the partition plate 19. The crushed stones on the upper part of the partition plate 19 are discharged through the cloth. The material is discharged from the feeder 6 and can be used for paving. The motor 24 drives the feed roller 22 to rotate. When the crushed stones on the upper part of the partition plate 19 enter the interior of the guide box 23, the feed roller 22 quantitatively discharges the crushed stones into the interior of the distribution box 21. Several groups of guide plates 26 are symmetrically arranged in an eight-shaped shape. The crushed stones enter the interior of the distribution box 21 and are divided into several parts by the vertical partitions 25. The crushed stones are guided and transported by the guide plates 26 symmetrically arranged in the eight-shaped shape so that the crushed stones are evenly laid on the ground.

[0053] By providing the inclined slider 31, the crushed stone processing device for mine restoration can be used to crush stones of different sizes, thereby improving its flexibility in use.

[0054] During operation, the user rotates the screw rod 30 so that the screw rod 30 drives the inclined slider 31, and the inclined slider 31 drives the adjusting roller 28 to move, thereby adjusting the distance between the adjusting roller 28 and the crushing roller 27. When the crushed stone passes between the adjusting roller 28 and the crushing roller 27, the rotation of the adjusting roller 28 and the crushing roller 27 can complete the crushing process of the crushed stone. The adjusting roller 28 and the crushing roller 27 can be driven by the motor to rotate, and the distance between them can be adjusted to allow crushed stones of different sizes to be accommodated between the adjusting roller 28 and the crushing roller 27. Secondly, the upper end of the inclined slider 31 adopts an inclined structure design, so that the inclined slider 31 has a crushed stone guiding function, which can guide the crushed stone between the adjusting roller 28 and the crushing roller 27, and can be adjusted according to the degree of crushing of the crushed stone. When the distance between the adjusting roller 28 and the crushing roller 27 is large, the volume of the crushed stone is large, and when the distance between the adjusting roller 28 and the crushing roller 27 is small, the volume of the crushed stone is small.
