Description

Technical Field

[0001] This invention belongs to the field of mine restoration, and more specifically, it is a crushed stone processing device for mine restoration. Background Technology

[0002] Mining activities have long faced the dual challenges of overexploitation of resources and damage to the ecological environment. The large amounts of waste rock, tailings, and fractured rock generated during open-pit mining or underground tunneling not only occupy land resources but also pose a serious threat to the safety of surrounding ecosystems due to soil erosion and heavy metal pollution caused by rainwater runoff. Traditional treatment methods mainly involve simple stockpiling, but this approach is inefficient and prone to secondary pollution, failing to meet the needs of modern mine green transformation and ecological restoration.

[0003] Application document CN111686845A describes a screenable crushing and processing device for mine stones. One end of the feed box has a feed inlet, and the bottom of the feed box is bolted to a pressing mechanism. The pressing mechanism includes a pressing box, a pressing chamber, a mounting plate, a fixed clamping plate, a sliding groove, a sliding plate, a movable clamping plate, a push plate, a limiting plate, an elliptical rotating rod, a first rotary motor, a sleeve, a fixed rod, and a tension spring. The pressing box is bolted to the bottom of the feed box. The structure is scientifically sound and safe to use. The pressing mechanism performs the first-stage crushing of the stone material through the pressing box. The first rotary motor drives the elliptical rotating rod to rotate, and the push plate continuously pushes the movable clamping plate to move.

[0004] The aforementioned processing device has certain shortcomings in ore crushing operations. While primarily designed for crushing ore, its functionality is limited. Manual sorting and handling of the crushed ore still require manual intervention, and the large volume of crushed ore increases the time required for this process. Furthermore, it lacks a ore recycling function. Secondly, the crushed ore cannot be directly utilized, further complicating its functionality and lacking extended auxiliary functions. It cannot be used directly after crushing. Additionally, during ore crushing, different sizes of crushed ore are prone to jamming, and the device cannot arbitrarily adjust the fineness of the crushed ore, highlighting its limited functionality. Summary of the Invention

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

[0006] The problem solved by this invention is:

[0007] 1. Traditional equipment mainly crushes quarry stones, which has a single function. Quarry stones still need to be manually picked up and sorted during crushing. The large amount of quarry stones increases the time required for picking up and sorting, and it does not have the function of crushed stone recycling. Secondly, the crushed stones cannot be used directly after crushing, which is a single function. It does not have the function of expanding auxiliary functions and cannot be used directly after crushing. At the same time, when crushing quarry stones, different sizes of stones are prone to jamming, and it cannot be arbitrarily adjusted according to the coarseness of the crushed stones, which is a single function.

[0008] The objective of this invention can be achieved through the following technical solutions:

[0009] A crushed stone processing device for mine restoration includes a receiving component and a screening box. The receiving component is movably installed at the front end of the screening box, and the receiving component and the screening box are movably connected by a lifting rod. A material distributor is fixedly installed at the rear end of the screening box. The receiving component includes a bucket and a movable material box. The bucket is movably installed at the front end of the movable material box, and the bottom of the movable material box is provided with several sets of screening rods distributed in an arc shape. Both sides of the bucket are inclined, and a conveying roller is movably installed at the end of the bucket. A conveyor belt is movably installed on the inner side of the bucket. The material distributor includes a material distribution box and a guide box. The material distribution box is fixedly installed on the lower outer surface of the guide box. By utilizing the receiving component, the crushed stone can be collected during the movement of the crushed stone processing device. The material distributor can evenly spread the crushed stone on the ground, making full use of the crushed stone for paving operations.

[0010] As a further technical solution of the present invention, a drive wheel is provided at the lower part of one end of the bucket. The drive wheel and the conveying roller are connected by a gear set, and the conveying roller and the conveyor belt are connected by a toothed chain structure. By using the movable bucket and the drive wheel installed at its bottom, the angle of one end of the bucket can be adjusted according to the undulation of the ground when the moving material box moves forward. When cleaning crushed stone, one end of the bucket can make better contact with the crushed stone. At the same time, the rotation of the drive wheel when it moves drives the conveying roller to rotate through the gear set. The conveying roller is located at one end of the bucket, so that the conveying roller contacts the crushed stone first. The rotation of the conveying roller guides the crushed stone into the bucket. The toothed chain structure enables the conveying roller to drive the conveyor belt, and the conveyor belt transports the crushed stone to the inside of the moving material box. The moving material box can carry a portion of the crushed stone, and the screening rod at the bottom of the moving material box can screen the mud and sand in the crushed stone.

[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 at the upper end of the screening box, and a discharge hopper is provided at the rear end of the movable box. When the movable box is full of crushed stone, the lifting rod is driven by the hydraulic rod to adjust the angle of the lifting rod, so that the lifting rod moves the receiving part upward and places the movable box 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 interior of the crushing box through the discharge hopper and 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. Both the inclined screen and the partition plate are inclined. A vibrator is provided at the bottom of the inclined screen. After the crushing box completes the crushing process of the crushed stone, the crushed stone enters the interior of the screening box. The vibrator drives the inclined screen to vibrate, so that the inclined screen completes the screening process of the crushed stone. A portion of the crushed stone is retained at the upper end of the inclined screen and discharged into the lower part of the partition plate through the discharge device. Another portion of the crushed stone passes through the inclined screen and is retained at the upper part of the partition plate. The partition plate collects the crushed stone in layers inside the screening box. The crushed stone at 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, both the bottom of the screening box and the movable box are equipped with casters. A driver's cab 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 move the receiving part. The casters at the bottom of the movable box can reduce the friction when it moves.

[0014] As a further technical solution of the present invention, a conveying roller is movably installed inside the guide box, and one end of the conveying roller is driven by a motor. The conveying roller is driven to rotate by the motor. When the crushed stone on the upper part of the partition plate enters the interior of the guide box, the crushed stone is quantitatively discharged into the interior of the cloth box by the conveying roller.

[0015] As a further technical solution of the present invention, the inside of the fabric box is fixedly installed with vertical partitions and guide plates. The guide plates are fixedly installed at the lower end of the vertical partitions. There are several sets of vertical partitions and guide plates. The several sets of guide plates are arranged symmetrically in a figure-eight shape. When the crushed stone enters the inside of the fabric box, the vertical partitions divide the crushed stone into several parts. The symmetrically arranged figure-eight guide plates guide and transport the crushed stone, so that the crushed stone is evenly laid on the ground.

[0016] As a further technical solution of the present invention, the inside of the fabric box is provided with several sets of material dispersing plates at the lower end of the guide plate. The several sets of material dispersing plates are distributed vertically at equal intervals. By using the material dispersing plates, the crushed stone can pass through the material dispersing plates when it is discharged, and the accumulated crushed stone 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. A discharge nozzle is fixedly installed at the lower end of the crushing box. The crushing of the stone can be completed by rotating the crushing roller and the adjusting roller. The crushed stone 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. The adjusting roller and the crushing box are movably connected by the inclined slider. The upper end of the inclined slider is inclined. The rear end of the inclined slider is provided with a telescopic guide rod and a lead screw. The lead screw and the inclined slider are movably connected. The user rotates the lead screw to drive the inclined slider, which in turn drives the adjusting roller to move, thereby adjusting the distance between the adjusting roller and the crushing roller. This allows different sizes of crushed stones to be used between the adjusting roller and the crushing roller. Furthermore, the upper end of the inclined slider adopts an inclined structure design, which enables the inclined slider to have a crushed stone guiding function, allowing the crushed stones to be guided between the adjusting roller and the crushing roller.

[0019] The beneficial effects of this invention are:

[0020] 1. By setting up a receiving component, the crushed stone processing device for mine restoration has an automatic crushed stone recycling structure when in use, which improves the crushed stone recycling efficiency of the mine and can also complete the preliminary sorting of crushed stone, thereby improving its crushed stone recycling effect.

[0021] During operation, the movable bucket, along with its drive wheels at the bottom, allows one end of the bucket to adjust its angle according to ground undulations as the moving hopper advances. This ensures better contact between the bucket and the small stones during gravel removal. Because traditional bucket structures create height variations during movement, the gravel passes through the bottom of the bucket. Simultaneously, the rotation of the drive wheels drives the conveyor rollers via a gear set. Located at one end of the bucket, the conveyor rollers are the first to contact the gravel. As the bucket moves forward, the rotation of the conveyor rollers guides the gravel into the bucket. Inside, a toothed chain structure drives the conveyor belt via conveyor rollers, which transports the crushed stone to the interior of the movable hopper. The movable hopper can hold a portion of the crushed stone, reducing the need for frequent side-spinning loading operations by the bucket. The screening rod at the bottom of the movable hopper can screen out the mud and sand in the crushed stone. When the movable hopper is full, a hydraulic rod drives a lifting rod, adjusting its angle to move the receiving component upwards, placing the movable hopper above the crushing hopper. Simultaneously, the discharge hopper aligns with the crushing hopper, allowing the crushed stone to be poured into the interior of the crushing hopper for further crushing.

[0022] 2. By setting up a feeder and an inclined screen, the crushed stone processing device for mine restoration can complete the recycling, crushing, screening and paving operations of crushed stone. It can quickly convert the crushed stone into paving stone and quickly solve the problem of crushed stone accumulation in the mine.

[0023] In use, after the crushing bin completes the crushing process, the crushed stone enters the screening bin. The vibrator drives the inclined screen to vibrate, which in turn screens the stone. Some of the stone remains at the top of the inclined screen and is discharged to the bottom of the partition plate via the discharge device. The other part of the stone passes through the inclined screen and remains at the top of the partition plate. The partition plate layers the stone inside the screening bin. The stone at the top of the partition plate is discharged by the distributor and can be used for paving. The motor drives the conveying roller to rotate. When the stone at the top of the partition plate enters the guide box, the conveying roller discharges a fixed amount of stone into the distribution box. Several sets of guide plates are symmetrically arranged in a figure-eight pattern. The stone enters the distribution box and is divided into several parts by vertical partitions. The symmetrically arranged figure-eight guide plates then guide and transport the stone, ensuring that the stone is evenly spread on the ground.

[0024] 3. By setting an inclined slider, the crushing and processing device for mine restoration can be used to crush stones of different sizes, thus improving its flexibility in use.

[0025] During operation, the user rotates the lead screw, which drives the inclined slider. The inclined slider then moves the adjusting roller, thereby adjusting the distance between the adjusting roller and the crushing roller. When the crushed stone passes between the adjusting roller and the crushing roller, the rotation of the adjusting roller and the crushing roller completes the crushing process. The motor can drive the adjusting roller and the crushing roller to rotate, and the distance between them can be adjusted to accommodate different sizes of crushed stone. Furthermore, the upper end of the inclined slider adopts an inclined structure design, which enables the inclined slider to guide the crushed stone between the adjusting roller and the crushing roller. It can also be adjusted according to the degree of crushing. When the distance between the adjusting roller and the crushing roller is larger, the volume of crushed stone is larger; when the distance between the adjusting roller and the crushing roller is smaller, the volume of crushed stone is smaller.

[0037] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] like Figure 1-9 As shown, a crushed stone processing device for mine restoration includes a receiving component 1 and a screening box 7. The receiving component 1 is movably installed at the front end of the screening box 7, and the receiving component 1 and the screening box 7 are movably connected by a lifting rod 4. A material distributor 6 is fixedly installed at the rear end of the screening box 7. The receiving component 1 includes a bucket 2 and a movable material box 3. The bucket 2 is movably installed at the front end of the movable material box 3, and the bottom of the movable material box 3 is provided with several sets of screening rods 12 arranged in an arc shape. Both sides of the bucket 2 are inclined. A conveying roller 13 is movably installed at the end of the bucket 2, and a conveyor belt 14 is movably installed on the inner side of the bucket 2. The material distributor 6 includes a material distribution box 21 and a guide box 23. The material distribution box 21 is fixedly installed on the lower outer surface of the guide box 23. By using the receiving component 1, the crushed stone can be collected during the movement of the crushed stone processing device. The crushed stone can be evenly spread on the ground by the material distributor 6, making full use of the crushed stone for paving operations.

[0039] To solve the problem of automatic recycling of crushed stone, such as Figure 2As shown, a drive wheel 15 is installed at the lower part of one end of the bucket 2. The drive wheel 15 and the conveying roller 13 are connected by a gear set 17. The conveying roller 13 and the conveyor belt 14 are connected by a toothed chain structure. By using the movable bucket 2 and the drive wheel 15 installed at its bottom, the angle of one end of the bucket 2 can be adjusted according to the undulation of the ground when the moving material box 3 moves forward. When cleaning crushed stone, one end of the bucket 2 can make better contact with the crushed stone. At the same time, the drive wheel can be used to... The rotation of the conveying roller 13 during movement is driven by the gear set 17. The conveying roller 13 is located at one end of the bucket 2, so that the conveying roller 13 is the first to contact the crushed stone. The rotation of the conveying roller 13 guides the crushed stone into the bucket 2. The toothed chain structure enables the conveying roller 13 to drive the conveyor belt 14, which transports the crushed stone to the interior of the moving material box 3. The moving material box 3 can carry a portion of the crushed stone. The screening rod 12 at the bottom of the moving material box 3 can screen the mud and sand in the crushed stone.

[0040] The lifting rod 4 and the screening box 7 are driven by a hydraulic rod 16. The upper end of the screening box 7 is fixedly installed with a crushing box 10. The rear end of the movable box 3 is provided with a discharge hopper 18. When the movable box 3 is full of crushed stone, the lifting rod 4 is driven by the hydraulic rod 16 to adjust the angle of the lifting rod 4, so that the lifting rod 4 drives the receiving part 1 to move upward, placing the movable box 3 above the crushing box 10. At the same time, the discharge hopper 18 is aligned with the crushing box 10, so that the crushed stone is poured into the interior of the crushing box 10 through the discharge hopper 18, and the crushing box 10 crushes the stone.

[0041] An inclined screen 9 is fixedly installed inside the screening box 7, and a partition plate 19 is fixedly installed below the inclined screen 9 inside the screening box 7. Both the inclined screen 9 and the partition plate 19 are inclined. A vibrator is provided at the bottom of the inclined screen 9. After the crushing box 10 completes the crushing process of the crushed stone, the crushed stone enters the interior of the screening box 7. The vibrator drives the inclined screen 9 to vibrate, so that the inclined screen 9 completes the screening process of the crushed stone. Some of the crushed stone is retained at the upper end of the inclined screen 9 and discharged into the lower part of the partition plate 19 through the discharge device 8. The other part of the crushed stone passes through the inclined screen 9 and is retained at the upper part of the partition plate 19. The crushed stone is layered and collected inside the screening box 7 through the partition plate 19. The crushed stone at 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, both the bottom of the screening box 7 and the movable box 3 are equipped with casters 20. The driver's cab 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 move the receiving part 1. The casters 20 at the bottom of the movable box 3 can reduce the friction when it moves.

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

[0044] like Figure 6 As shown, the inside of the material distribution box 21 is fixedly installed with vertical partitions 25 and guide plates 26. The guide plates 26 are fixedly installed at the lower end of the vertical partitions 25. There are several sets of vertical partitions 25 and guide plates 26. The several sets of guide plates 26 are arranged symmetrically in a figure-eight shape. When the crushed stone enters the inside of the material distribution box 21, the vertical partitions 25 divide the crushed stone into several parts, and the symmetrically arranged figure-eight guide plates 26 guide and transport the crushed stone, so that the crushed stone is evenly laid on the ground.

[0045] Inside the material box 21, at the lower end of the guide plate 26, there are several sets of material dispersing plates 32. The sets of material dispersing plates 32 are vertically and equally spaced. By using the material dispersing plates 32, the crushed stone can pass through the material dispersing plates 32 when it is discharged, and the accumulated crushed stone 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 crushing of the stone can be completed by rotating the crushing roller 27 and the adjusting roller 28. The crushed stone is discharged downward through the discharge nozzle 29.

[0047] An inclined slider 31 is provided on one side of the adjusting roller 28. The adjusting roller 28 and the crushing box 10 are movably connected through the inclined slider 31. The upper end of the inclined slider 31 is inclined. The rear end of the inclined slider 31 is provided with a telescopic guide rod 11 and a lead screw 30. The lead screw 30 and the inclined slider 31 are movably connected. The user rotates the lead screw 30, which drives the inclined slider 31. 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. This allows different sizes of crushed stone to be used between the adjusting roller 28 and the crushing roller 27. In addition, the upper end of the inclined slider 31 adopts an inclined structure design, which gives the inclined slider 31 a crushed stone guiding function, which can guide the crushed stone between the adjusting roller 28 and the crushing roller 27.

[0048] Traditional equipment primarily crushes ore from mines, offering limited functionality. During crushing, manual sorting and handling of the crushed ore is still required, and the large volume of crushed ore increases the time needed for this process. Furthermore, it lacks a ore recycling function. Secondly, the crushed ore cannot be directly utilized, further limiting its functionality and providing no auxiliary functions. It also cannot be used directly after crushing. Additionally, during ore crushing, different sizes of ore are prone to jamming, and the equipment cannot arbitrarily adjust the fineness of the crushed ore, resulting in limited functionality.

[0049] Therefore, when in use, by setting up receiving component 1, the crushed stone processing device for mine restoration has an automatic crushed stone recycling structure, which improves the crushed stone recycling efficiency of the mine and can also complete the preliminary sorting of crushed stone, thereby improving its crushed stone recycling effect.

[0050] During operation, the movable bucket 2, in conjunction with the drive wheel 15 mounted at its bottom, allows one end of the bucket 2 to adjust its angle according to the ground undulations as the moving material box 3 moves forward. This ensures better contact between the bucket 2 and the gravel during cleaning. Because the gravel is relatively small, the traditional bucket 2 structure experiences height changes during movement, allowing the gravel to pass through the bottom of the bucket 2. Simultaneously, the rotation of the drive wheel 15 drives the conveying roller 13 to rotate via the gear set 17. The conveying roller 13, located at one end of the bucket 2, is the first to contact the gravel. As the bucket 2 moves forward, the rotation of the conveying roller 13 guides the gravel into the bucket 2, where it is then processed by the gear set 17. The chain structure enables the conveying roller 13 to drive the conveyor belt 14, which in turn transports the crushed stone to the interior of the mobile material box 3. The mobile material box 3 can carry a portion of the crushed stone, so that the bucket 2 does not need to perform frequent side-spinning feeding operations. The screening rod 12 at the bottom of the mobile material box 3 can screen the mud and sand in the crushed stone. When the mobile material box 3 is full of crushed stone, the hydraulic rod 16 drives the lifting rod 4, thereby adjusting the angle of the lifting rod 4, so that the lifting rod 4 moves the receiving part 1 upward, placing the mobile material box 3 above the crushing box 10. At the same time, the discharge hopper 18 is aligned with the crushing box 10, so that the crushed stone is poured into the interior of the crushing box 10 through the discharge hopper 18, and the crushing box 10 crushes the crushed stone.

[0051] By setting up the feeder 6 and the inclined screen 9, the crushed stone processing device for mine restoration can complete the recycling, crushing, screening and paving operations of crushed stone respectively when in use. It can quickly convert the crushed stone into paving stone and quickly solve the problem of crushed stone accumulation in the mine.

[0052] In use, after the crushing bin 10 completes the crushing process, the crushed stone enters the screening bin 7. A vibrator drives the inclined screen 9 to vibrate, causing the inclined screen 9 to screen the stone. A portion of the stone remains at the upper end of the inclined screen 9 and is discharged to the lower part of the partition plate 19 via the discharge device 8. The remaining stone passes through the inclined screen 9 and remains at the upper part of the partition plate 19. The partition plate 19 then layers the stone within the screening bin 7. The stone at the upper part of the partition plate 19 is then separated by a cloth... The material is discharged from the feeder 6 and can be used for paving. The electric motor 24 drives the conveying roller 22 to rotate. When the crushed stone above the partition plate 19 enters the interior of the guide box 23, the conveying roller 22 discharges the crushed stone quantitatively into the interior of the distribution box 21. Several sets of guide plates 26 are symmetrically arranged in a figure-eight shape. The crushed stone enters the interior of the distribution box 21 and is divided into several parts by the vertical partition plate 25. The crushed stone is then guided and conveyed by the symmetrically arranged figure-eight guide plates 26, so that the crushed stone is evenly laid on the ground.

[0053] By setting the inclined slider 31, the crushing and processing device for mine restoration can be used to crush stones of different sizes, thus improving its flexibility in use.

[0054] During operation, the user rotates the lead screw 30, which drives the inclined slider 31. The inclined slider 31 then moves the adjusting roller 28, 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 completes the crushing process. The motor can drive the adjusting roller 28 and the crushing roller 27 to rotate, and the distance between them can be adjusted to accommodate different sizes of crushed stone. Furthermore, the upper end of the inclined slider 31 adopts an inclined structure design, which gives the inclined slider 31 a crushed stone guiding function, allowing the crushed stone to be guided between the adjusting roller 28 and the crushing roller 27. At the same time, the distance 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 larger, the volume of the crushed stone is larger; when the distance between the adjusting roller 28 and the crushing roller 27 is smaller, the volume of the crushed stone is smaller.
