Description

Technical Field

[0001] The present invention relates to the technical field of coal mine solid waste filler treatment, and in particular to a road paving and compacting device using coal mine associated solid waste filler. Background Art

[0002] Coal mines produce a large amount of gangue during the production process. The sandy mudstone and sandstone contained in the gangue can be used as engineering gravel. Therefore, the materials that can be used as engineering gravel will be used for road paving.

[0003] When the existing paving device lays engineering gravel, its moving speed is proportional to the engineering gravel discharge speed. However, when paving a curved road surface, during the turning process of the paving device, the inner radius of the circle in which the paving device turns is smaller than the outer radius of the circle, while the speed of the engineering gravel laid by the paving device remains the same. In this process, the engineering gravel on the inner circle of the paving device will accumulate, while the engineering gravel on the outer circle will become thinner, which will eventually cause the thickness of the engineering gravel laid on the curved road surface to be uneven, affecting the road paving effect.

The mounting plates and the feeding box are both provided with sliding grooves. The upper and lower adjacent sliding grooves cooperate to form a one-word groove for guiding. Second driving members are symmetrically installed at the lower part of the feeding box. The telescopic ends of adjacent second driving members are rotatably connected through a bushing with spiral conveying rollers for spreading the solid waste filler.

[0016] Through the rotational speed difference formed by the wheels on the short-arc side and the wheels on the long-arc side, the two baffle plates are in a V-shaped configuration, and the side with the smaller opening is located on the short-arc side, so that the dropping amount on the short-arc side is less than that on the long-arc side, achieving the same stacking height of the dropping amount on the short-arc side and the stacking height of the dropping amount on the long-arc side. By continuously moving the ramming plate downward to compact the solid waste filler, the mechanical strength and stability of the paved road against the action of vehicle loads are improved;

[0017] By adjusting the distance between the front and rear moving disks, the paving height of the road surface is adjusted. Through the rotation of the spiral conveyor roller, the solid waste filler on both sides is spread evenly to both sides to prevent uneven filling and feeding of the solid waste filler on the road. The scraping plate moves to level the paved solid waste filler. Description of the Drawings

[0026] Reference to an embodiment herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present invention. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments.

[0027] Embodiment 1

[0028] A road paving and compressing equipment for filling with coal mine associated solid waste, as Figures 1-4As shown in the figure, it includes a mobile vehicle 1. The lower part of the mobile vehicle 1 is rotationally connected with wheels through axles. A differential is provided on the axles. Speed increasing boxes 2 are embedded in the front and rear side walls of the mobile vehicle 1. The speed increasing boxes 2 are used to increase the transmission speed. The outer shafts of the speed increasing boxes 2 on the front and rear sides are driven by sprockets and chains with the left axle of the mobile vehicle 1. Inside the mobile vehicle 1, a feeding box 3 for storing solid waste fillers is fixedly connected through a connecting plate. The feeding box 3 is set to be inclined to reduce the influence of the gravity of the solid waste fillers on the feeding speed. On the front and rear parts inside the mobile vehicle 1, bearing plates 4 are fixedly connected through bolts. The upper side of the bearing plate 4 is slidably connected with symmetrically distributed moving frames 5. A first tension spring 6 is fixedly connected between the upper parts of the adjacent left and right moving frames 5. Insertion plates 7 are respectively rotationally connected to the two sides of the moving frames 5. A fixing plate 8 is slidably connected between the insertion plates 7. The fixing plate 8 is fixedly connected with a baffle plate 9 slidably connected with the feeding box 3. An outlet is formed between the two left and right baffle plates 9. The change in the size of the outlet is used to adjust the feeding amounts on the long arc side and the short arc side during the turning process. The feeding box 3 is symmetrically rotationally connected with rotating frames 10 through connecting plates. The rotating frames 10 on the front and rear sides are respectively driven by belt wheels and belts with the inner shafts of the speed increasing boxes 2 on the front and rear sides. The rotation of the wheels drives the rotation of the outer shafts of the speed increasing boxes 2 through sprockets and chains. The power is accelerated by the speed increasing boxes 2, and the rotating frames 10 are driven to rotate through belt wheels and belts. Six circumferentially equally spaced contact blocks 11 for pushing the moving frames 5 to move are slidably connected to the rotating frames 10. An extrusion spring 12 is fixedly connected between the contact blocks 11 and the rotating frames 10.

[0029] As Figure 1 and Figure 2 shown, on the left side of the inner top of the mobile vehicle 1, a first driving member 16 is bolted through a mounting seat. The first driving member 16 is a double-shaft motor. Both the front and rear output ends of the first driving member 16 are fixedly connected with mounting shafts. A first rotating shaft 17 is rotationally connected through the feeding box 3 inside the mobile vehicle 1. The first rotating shaft 17 is located above the baffle plate 9. The first rotating shaft 17 is driven by belt wheels and belts with the mounting shafts of the first driving member 16. A stirring roller 18 for conveying solid waste fillers is fixedly connected to the first rotating shaft 17 inside the feeding box 3. When the first driving member 16 works, the first rotating shaft 17 is driven through the mounting shafts and belt wheels and belts to drive the stirring roller 18 to rotate to convey the solid waste fillers in the feeding box 3 downward.

[0030] As Figure 2As shown in the figure, two symmetrically distributed fixing frames 19 are fixedly connected to the right part of the upper side of the mobile vehicle 1. A material hopper 20 for placing solid waste fillers is slidably connected between the left and right fixing frames 19. The lower part of the material hopper 20 is located inside the feeding box 3, and the width of the lower part of the material hopper 20 is smaller than the width of the feeding port of the feeding box 3 to prevent the solid waste fillers from scattering. Swing wheels 21 for the material hopper 20 to shake itself are rotatably connected to the front and rear walls of the material hopper 20 through connecting rods. The connecting rods of the swing wheels 21 are driven by belt wheels and belts between the first rotating shaft 17. The first rotating shaft 17 rotates through belt wheels and belts, and the inertia generated by driving the swing wheels 21 to rotate drives the material hopper 20 to shake left and right, so that the solid waste fillers in the material hopper 20 are shaken evenly. Tensioning members 211 are arranged on the front and rear walls inside the mobile vehicle 1, and the tensioning members 211 make the belt between the connecting rods of the swing wheels 21 and the first rotating shaft 17 taut. Fixing blocks 22 are fixedly connected to the fixing frames 19 at equal intervals, and springs for buffering the shaking amplitude of the material hopper 20 are fixedly connected between the fixing blocks 22 and the material hopper 20.

[0031] As Figure 5 shown, a second rotating shaft 23 is rotatably connected to the lower part of the mobile vehicle 1. The second rotating shaft 23 is located directly below the material hopper 20. The second rotating shaft 23 and the first rotating shaft 17 are driven by belt wheels and belts. Eccentric wheels 24 are fixedly connected to the front and rear parts of the second rotating shaft 23. Two connecting frames 25 that are both rotatably connected to the second rotating shaft 23 are fixedly connected to the right wall inside the mobile vehicle 1. A ramming plate 26 for compacting the solid waste fillers is slidably connected to the lower part of the adjacent connecting frames 25. A second tension spring 27 for pulling the ramming plate 26 to move upward is fixedly connected between the connecting frames 25 and the ramming plate 26. The first rotating shaft 17 drives the second rotating shaft 23 through belt wheels and belts, and the second rotating shaft 23 drives the eccentric wheels 24 to push the ramming plate 26 downward to compact the solid waste fillers.

[0032] A method for paving and compacting coal mine associated solid waste fillers for road construction, applying the above-mentioned equipment for paving and compacting coal mine associated solid waste fillers for road construction, the method includes the following steps:

[0033] When using the present invention, the user moves the mobile vehicle 1 to the road surface, and the user pours the solid waste filler into the hopper 20. The solid waste filler in the hopper 20 falls downward into the feeding box 3. Since the feeding box 3 is arranged in an inclined shape, most of the gravity of the solid waste filler is offset by the upward supporting force of the inclined side wall of the feeding box 3, thereby reducing the influence of the total gravity of the solid waste filler in the hopper 20 on the feeding speed. The user starts the first driving member 16 to drive the installation shaft connected thereto to rotate. The rotation of the installation shaft drives the first rotating shaft 17 through a belt pulley and a belt, and drives the stirring roller 18 to rotate to convey the solid waste filler downward. Moreover, the rotation of the stirring roller 18 stirs the solid waste filler to move, preventing the solid waste filler from blocking the feeding box 3. The rotation of the first rotating shaft 17 drives the swing wheel 21 to rotate through a belt pulley and a belt. The inertia generated by the rotation of the swing wheel 21 drives the hopper 20 to shake, and shakes the solid waste filler therein evenly for feeding. The shaking of the hopper 20 is buffered by the fixing block 22 and the spring thereon. The user controls the movement of the mobile vehicle 1. After being accelerated by the axle, the belt pulley and the belt and transmitted to the speed increasing box 2, the rotating frame 10 starts to rotate. The centrifugal force generated by the rotation of the rotating frame 10 cooperates with the thrust of the compression spring  12 to push the contact block 11 to push the moving frame 5 outward to move. The moving frames  5 on the left and right sides move away from each other, and the fixing plates 8 on the left and right sides move away from each other through the insertion plates 7 thereon, so that the discharge port between the baffle plates 9 is opened, expanding the falling amount of the solid waste filler in the feeding box 3. The moving speed of the mobile vehicle 1 is proportional to the moving distance of the two baffle plates 9. The solid waste filler in the feeding box 3 falls downward onto the road surface. The rotation of the first rotating shaft 17 drives the second rotating shaft 23 through a belt pulley and a belt, driving the eccentric wheel 24 to rotate, pushing the ramming plate 26 to move downward to compact the laid solid waste filler. The second tension spring 27 is stretched accordingly. After the eccentric wheel 24 rotates away from the ramming plate 26, under the action of the second tension spring 27, the ramming plate 26 returns upward. By continuously moving the ramming plate 26 downward to compact the solid waste filler, the mechanical strength and stability of the laid road against the action of vehicle loads are improved.

[0034] When turning, since the moving distance of the inner circle of the turn is less than that of the outer circle, the rotational speed of the wheels on the short-arc side is lower than that of the wheels on the long-arc side. The wheels on the short-arc side drive the rotating frame 10 on the same side to rotate through the axle, and the wheels on the long-arc side drive the rotating frame 10 on the same side to rotate through the axle. There is a rotational speed difference between the front and rear rotating frames 10. The distance that the rotating frame 10 on the short-arc side rotates to push the baffle plate 9 away is less than the distance that the rotating frame 10 on the long-arc side rotates to push the baffle plate 9 away. The long-arc sides of the two baffle plates 9 move away from each other, causing the plug board 7 on the same side to move outwards. Moreover, the plug board 7 is rotatably connected to the moving frame 5, making the two baffle plates 9 in a shape like an eight with the side with a smaller opening located on the short-arc side, so that the dropping amount on the short-arc side is less than that on the long-arc side, achieving the same height of the dropping amount on the short-arc side as that on the long-arc side. Through the above steps, when the mobile vehicle 1 turns, the dropping amounts of the solid waste fillers on the short-arc side and the long-arc side are adjusted, so that the total amount of the solid waste fillers dropped on the road surface during the turning process is the same as the dropping amount during straight running, avoiding excessive dropping amount of the solid waste fillers on the short-arc side during turning and affecting the road paving.

[0035] Embodiment 2

[0036] On the basis of Embodiment 1, as Figure 4 shown, it further includes symmetrically arranged screw rods 13. The screw rods 13 are rotatably connected to the rotating frame 10. The rotating frame 10 is provided with a sliding groove 131. A moving disk 14 is slidably connected in the sliding groove 131. The moving disk 14 is threadedly connected to the adjacent screw rod 13. The rotating frame 10 is circumferentially and equally spacedly slidably connected with mounting frames 15. The number of the mounting frames 15 is the same as the number of the contact blocks 11. The inner ends of the circumferentially arranged mounting frames 15 are respectively located in the circumferentially arranged contact blocks 11 and the sliding grooves of the rotating frame 10. An articulated rod is rotatably connected between the mounting frame 15 and the moving disk 14. The mounting frame 15 is fixedly connected to the adjacent compression spring 12. According to the height of the road paving, the screw rod 13 is rotated to adjust the distance between the contact block 11 and the moving frame 5 through the moving disk 14, facilitating the paving of solid waste fillers with different heights.

[0037] When paving the road, the user rotates the screw rod 13 to move the moving disk 14. The moving disk 14 moves through the articulated rod, the mounting frame 15 and the compression spring 12 to push the contact block 11 to move. The front and rear moving disks 14 move away from or close to each other, causing the contact block 11 to move outwards or inwards. When the moving disk 14 makes the contact block 11 move outwards away from each other, at the same rotational speed, the distance that the contact block 11 is pushed outwards becomes shorter, thereby reducing the distance between the moving frames 5 and narrowing the discharge port between the baffle plates 9 to reduce the discharge amount. Similarly, when the moving disk 14 makes the contact block 11 move inwards close to each other, the discharge port between the baffle plates 9 expands to increase the discharge amount, thereby realizing the adjustment of the dropping amount of the solid waste filler at the same rotational speed. The user can adjust the position of the contact block 11 according to the height of the road surface that needs to be paved, facilitating the paving of solid waste fillers with different heights on the road surface.

[0038] Example 3

[0039] Based on Example 2, as Figures 5-7 shown, it further includes a solid waste filler conveying assembly for laying the solid waste filler flat. The solid waste filler conveying assembly is arranged at the lower part of the feeding box 3. The solid waste filler conveying assembly is connected to the mobile vehicle 1. The solid waste filler conveying assembly includes symmetrically arranged mounting plates 28. The mounting plates 28 are fixedly connected to the bottom of the feeding box 3. Second driving members 29 are symmetrically installed at the lower part of the feeding box 3. The second driving members 29 are electric push rods. Both the mounting plates 28 and the feeding box 3 are provided with sliding grooves 291. The vertically adjacent sliding grooves 291 cooperate to form a one-word groove for guiding. The telescopic ends of adjacent second driving members 29 are rotatably connected to a spiral conveying roller 30 through a bushing. The height of the spiral conveying roller 30 is adjusted by the second driving member 29 to be suitable for paving roads with different heights. The spiral fan blades of the spiral conveying roller 30 are composed of two spiral fan blades with opposite spiral directions. The spiral conveying roller 30 is slidably connected in the one-word groove. A third driving member 31 fixedly connected to the spiral conveying roller 30 is slidably installed on the outer side of the mobile vehicle 1. The third driving member 31 is a reduction motor. The third driving member 31 rotates the spiral conveying roller 30, and the spiral conveying roller 30 spreads the solid waste filler on both sides to the front and back.

[0040] During the process of adjusting the position of the moving disk 14, the user starts the two second driving members 29 to move the spiral conveying roller 30 through the bushings on them. When the moving disks 14 on the front and back sides move away from each other, the user moves the spiral conveying roller 30 downward. When the moving disks 14 on the front and back sides move closer to each other, the user moves the spiral conveying roller 30 upward. When paving the road, the user starts the third driving member 31 to rotate the spiral conveying roller 30. Since the spiral fan blades of the spiral conveying roller 30 are composed of two spiral fan blades with opposite spiral directions, the spiral conveying roller 30 rotates to spread the solid waste filler in the middle to both sides. During this process, the uneven feeding of the solid waste filler on the road is leveled. By adjusting the height of the spiral conveying roller 30 and the feeding amount of the solid waste filler, it is convenient to control the paving height of the solid waste filler on the road surface.

[0041] As Figures 5-7As shown, it further includes a scraping component for removing excess solid waste fillers. The scraping component is arranged in the feeding box 3. The scraping component includes two moving rods 32, and the two moving rods 32 are respectively rotatably connected to the front and rear ends of the screw conveyor roller 30. A scraping plate 33 for removing excess solid waste fillers is slidably connected to the adjacent moving rod 32. The scraping plate 33 is located on the right side of the screw conveyor roller 30. The front and rear parts of the right side surface of the feeding box 3 are fixedly connected by bolts with guide plates 34 that are in limit sliding connection with the scraping plate 33. The movement of the screw conveyor roller 30 causes the scraping plate 33 to move through the moving rod 32 to adjust the height of the scraping plate 33. The guide plate 34 guides the movement of the scraping plate 33. The movement of the moving vehicle 1 drives the scraping plate 33 to move to level the laid solid waste fillers.
