Technical Field

[0001] The present invention relates to the technical field of separation, and particularly to a recycling device for road construction. Background Art

[0002] During road construction, sometimes it is necessary to renovate a local road surface. Specifically, a road surface cutting machine is needed to segmentally demolish the old road surface into multiple reinforced concrete slabs, and then the multiple reinforced concrete slabs are removed one by one from the ground. In order to recycle the demolished reinforced concrete slabs, in the prior art, the reinforced concrete slabs are usually broken by a jaw crusher to separate the concrete blocks and the steel bars from each other.

[0003] Since the length of the steel bars is very long and it is also very difficult to be cut off by the jaw crusher, during the crushing process, the steel bars are easily blocked in the jaw crusher, resulting in the inability to separate the concrete blocks and the steel bars from each other, and further causing the jaw crusher to be blocked. Summary of the Invention

[0011] Preferably, the separation component further includes a first eccentric shaft and a first movable constraint. The first eccentric shaft is rotatably connected to the top end of the movable clamping plate.

[0015] The beneficial effects of the present invention are: The present invention is provided with a separation component. Before the reinforced concrete slab enters the crushing component, the separation component first breaks the reinforced concrete slab into steel bars and concrete blocks. At this time, the concrete blocks with sizes smaller than the second crushing protrusions roll into the interior of the crushing component under the action of their own gravity, while the steel bars, due to their long lengths, are clamped between the second crushing protrusions and cannot fall. After the moving clamping plate reaches the preset working duration, the control module controls the electromagnet to be energized for a preset duration. At this time, the electromagnet generates magnetism and attracts the steel bars onto the crushing plane facing the moving clamping plate. During the process of the electromagnet being energized for the preset duration, the rotating column rotates by a preset angle so that the crushing plane with the attracted steel bars rotates to a position away from the upper surface of the moving clamping plate. At this time, the electromagnet is powered off. After losing the magnetic force, the steel bars are no longer attracted to the rotating column and fall to both sides of the frame under the action of their own gravity. In this way, the steel bars and the second crushing protrusions are separated, preventing the steel bars from entering the crushing component together with the concrete blocks and avoiding blockage inside the crushing component.

[0021] As Figures 1 to 11 shown, a recycling device for road construction is used to recycle reinforced concrete slabs. The recycling device for road construction includes a frame 100, a separation component 200, a control module and a crushing component 300. The separation component 200 is arranged on the upper part of the frame 100 and is used to separate the reinforced concrete slab into steel bars and concrete blocks. The separation component 200 includes a fixed shaft 210, a rotating column 220, an electromagnet 230 and a movable clamping plate 240. The fixed shaft 210 is arranged on the upper part of the frame 100, and the axis of the fixed shaft 210 is arranged at an angle with the horizontal plane. The electromagnet 230 is arranged at a position biased downward inside the fixed shaft 210. The rotating column 220 is rotatably arranged on the outer periphery of the fixed shaft 210 and can rotate around its axis. A plurality of crushing planes 221 are circumferentially and equally spaced on the outer periphery of the rotating column 220, and a number of first crushing protrusions 222 are evenly arranged on the crushing planes 221. The movable clamping plate 240 is obliquely arranged on the frame 100 and is located below the rotating column 220. A number of second crushing protrusions 241 are evenly arranged on the upper surface of the movable clamping plate 240. The first crushing protrusions 222 and the second crushing protrusions 241 are staggered with each other. The movable clamping plate 240 can reciprocally approach or move away from the rotating column 220. The control module is used to control the electromagnet 230 to be intermittently powered on, and the control module is configured to control the electromagnet 230 to be powered on for a set duration after the movable clamping plate 240 reciprocally approaches or moves away from the rotating column 220 for a preset duration and stops. The control module is also used to control the rotation of the rotating column 220, and the control module is configured to control the rotating column 220 to rotate a preset angle during the process of the electromagnet 230 being powered on for the set duration. The crushing component 300 is arranged on the frame 100 and is located below the separation component 200, and is used to crush the separated concrete blocks.

[0022] In use, the staff places the reinforced concrete slab between the movable clamping plate 240 and the crushing plane 221 facing the movable clamping plate 240 from one side of the frame 100, and then makes the movable clamping plate 240 reciprocate close to or away from the rotating column 220 for a preset time. When the movable clamping plate 240 approaches the rotating column 220, the distance between the upper surface of the movable clamping plate 240 and the crushing plane 221 of the rotating column 220 decreases. Under the action of the second crushing protrusion 241 and the first crushing protrusion 222, the reinforced concrete slab is compressed and broken into steel bars and concrete blocks. When the movable clamping plate 240 moves away from the rotating column 220, the distance between the upper surface of the movable clamping plate 240 and the crushing plane 221 of the rotating column 220 increases. At this time, the concrete blocks smaller than the distance between the second crushing protrusions 241 roll into the crushing assembly 300 under their own gravity, so that the crushing assembly 300 can further break the concrete blocks into the required particle size. Since the steel bars are relatively long, they are clamped between the second crushing protrusions 241 and cannot fall. After the movable clamping plate 240 reciprocates close to or away from the rotating column 220 for a preset time and stops, the control module controls the electromagnet 230 to be energized for a preset time. At this time, the electromagnet 230 generates magnetism and attracts the steel bars to the crushing plane 221 facing the movable clamping plate 240. During the process of the electromagnet 230 being energized for a preset time, the rotating column 220 rotates a preset angle so that the crushing plane 221 with the attracted steel bars rotates away from the upper surface of the movable clamping plate 240, and the crushing plane 221 without the attracted steel bars rotates to face the movable clamping plate 240. Next, the electromagnet 230 is powered off. At this time, the steel bars are no longer attracted to the rotating column 220, and the steel bars fall to both sides of the frame 100 under their own gravity. In this way, the steel bars and the second crushing protrusions 241 are separated, preventing the steel bars from entering the crushing assembly 300 together with the concrete blocks and preventing blockage inside the crushing assembly 300. Next, similarly, the movable clamping plate 240 continues to reciprocate close to or away from the rotating column 220 for a preset time, and the reinforced concrete is continuously placed between the movable clamping plate 240 and the crushing plane 221 facing the movable clamping plate 240. When the time for the movable clamping plate 240 to reciprocate close to or away from the rotating column 220 reaches the preset time, the movable clamping plate 240 stops moving. Next, the electromagnet 230 is energized for a preset time. During the process of the electromagnet 230 being energized for a preset time, the rotating column 220 rotates a preset angle so that the crushing plane 221 with the attracted steel bars rotates away from the upper surface of the movable clamping plate 240, and the crushing plane 221 without the attracted steel bars rotates to face the movable clamping plate 240. Next, the above steps are repeated to complete the crushing of the entire batch of reinforced concrete.

[0023] It should be added that, in order to make the steel bars attracted to the crushing plane 221 fall more easily, specifically, the length of the first crushing protrusion 222 can be made shorter than the length of the second crushing protrusion 241.

[0024] It should also be added that, taking the number of the crushing planes 221 provided on the outer periphery of the rotating column 220 as six as an example, the preset angle of each rotation of the rotating column 220 is sixty degrees.

[0025] In this embodiment, a screening plate 250 is also elastically connected to the upper surface of the movable clamping plate 240. A plurality of screening holes 251 are formed on the surface of the screening plate 250, and a plurality of through holes 252 are also formed on the surface of the screening plate 250. The diameter of the through holes 252 is adapted to the size of the second crushing protrusions 241. The plurality of through holes 252 and the plurality of second crushing protrusions 241 are in one-to-one correspondence and are slidably matched.

[0026] The screening holes 251 are provided to separate the concrete powder generated during the crushing process from the concrete blocks, so that the concrete blocks roll down along the surface of the screening plate 250 into the crushing assembly 300, while the concrete powder leaks downward through the screening holes 251 to the upper surface of the movable clamping plate 240, realizing the separation of the concrete powder and the concrete blocks, and preventing the particle size difference of the concrete entering the crushing assembly 300 from being too large, which may cause the particle size difference of the concrete blocks discharged from the crushing assembly 300 to become even larger.

[0027] It can be understood that the through holes 252 are provided so that when the movable clamping plate 240 approaches the rotating column 220, the second crushing protrusions 241 can extend out from the through holes 252 to crush the reinforced concrete slab.

[0028] In this embodiment, a guiding inclined surface 242 is formed on the upper surface of the movable clamping plate 240. The guiding inclined surface 242 inclines downward from the center in the width direction of the movable clamping plate 240 to its left and right sides.

[0029] The guiding inclined surface 242 is provided to guide the concrete powder leaking from the screening plate 250, so that the concrete powder can fall more from the lower part of the movable clamping plate 240 and near its left and right sides, facilitating the centralized collection of the concrete powder.

[0030] In this embodiment, baffles 260 are detachably provided on the frame 100 and on the left and right sides of the movable clamping plate 240.

[0031] The baffles 260 are provided to prevent the concrete blocks during the crushing process from rolling off from the left and right sides of the movable clamping plate 240, and to prevent the concrete powder from falling from the left and right sides of the movable clamping plate 240.

[0032] It should be noted that for the convenience of feeding materials between the movable clamping plate 240 and the rotating column 220, the baffle 260 on the feeding side can be set to be hinged on the frame 100. When feeding materials, rotate the baffle 260 to expose enough gaps on the feeding side of the frame 100, so that the staff can put the reinforced concrete slab between the movable clamping plate 240 and the rotating column 220. After the feeding is completed, rotate the baffle 260 in the reverse direction to reset the baffle 260.

[0033] In this embodiment, a receiving box 110 is provided on the frame 100 and below the movable clamping plate 240. The receiving box 110 is used to guide the materials falling from the movable clamping plate 240, so that the materials falling from the movable clamping plate 240 are discharged from the left and right sides of the frame 100.

[0034] It can be understood that when the concrete powder falls from the lower part of the movable clamping plate 240, because it is close to the crushing assembly 300, the concrete powder is likely to fall into the crushing assembly 300. By providing the receiving box 110 on the frame 100 and below the movable clamping plate 240, the concrete powder falling from the movable clamping plate 240 can be received and discharged orderly from the left and right sides of the frame 100 under the guiding action of the receiving box 110.

[0035] In this embodiment, a first driving assembly 400 is provided on the upper part of the frame 100. The first driving assembly 400 includes a first driving motor 410, a gear 420 and a toothed ring 430. The first driving motor 410 is arranged on the upper part of the frame 100. The gear 420 is fixedly connected to the output shaft of the first driving motor 410. The toothed ring 430 is coaxially arranged at one end of the rotating column 220, and the toothed ring 430 meshes with the gear 420.

[0036] After the electromagnet 230 is powered on, the control module transmits an electrical signal to the first driving motor 410. At this time, the output end of the first driving motor 410 drives the gear 420 to rotate synchronously by a preset angle. The gear 420 drives the toothed ring 430 to rotate by a preset angle. Since the toothed ring 430 is coaxially arranged at one end of the rotating column 220, the rotating column 220 rotates synchronously by a preset angle, so that the crushing plane 221 attracting the steel bar rotates away from the upper surface of the movable clamping plate 240, and the crushing plane 221 not attracting the steel bar rotates to face the movable clamping plate 240.

[0037] In this embodiment, the separating assembly 200 further includes a first eccentric shaft 270 and a first movable constraint 280. The first eccentric shaft 270 is rotatably connected to the top end of the movable clamping plate 240. One end of the first movable constraint 280 is rotatably arranged on the frame 100, and the other end of the first movable constraint 280 is rotatably connected to the lower end of the movable clamping plate 240.

[0038] To drive the movable plate to approach or move away from the rotating column 220 reciprocally, specifically, the first eccentric shaft 270 rotates circumferentially. Under the rotation of the first eccentric shaft 270, the movable clamping plate 240 approaches or moves away from the rotating column 220 periodically, thereby reducing or increasing the distance between the movable clamping plate 240 and the rotating column 220, and realizing the crushing of the reinforced concrete slab.

[0039] It should also be supplemented that the first movable restraint 280 includes a first toggle plate 281, a first fixed seat 282, a first pull rod 283, a first limiting plate 284, a first fixed plate 285 and a first spring 286. Specifically, one end of the first toggle plate 281 is hinged to the movable clamping plate 240, and the other end of the first toggle plate 281 is hinged to the first fixed seat 282. The first fixed seat 282 is arranged on the frame 100. One end of the first pull rod 283 is hinged to the movable clamping plate 240 and is located below the first toggle plate 281. The first limiting plate 284 is arranged at the lower end of the first fixed seat 282. A first limiting hole 2841 is formed in the first limiting plate 284, and the diameter of the first limiting hole 2841 is larger than the diameter of the first pull rod 283. The end of the first pull rod 283 away from the movable clamping plate 240 passes through the first limiting hole 2841. The first fixed plate 285 is arranged at the end of the first pull rod 283 away from the movable clamping plate 240. The first spring 286 is sleeved outside the first pull rod 283, and one end of the first spring 286 is fixedly connected to the first fixed plate 285, and the other end is fixedly connected to the first limiting plate 284.

[0040] In this embodiment, the crushing assembly 300 includes a movable jaw plate 310, a fixed jaw plate 320, a second eccentric shaft 330 and a second movable restraint 340. The fixed jaw plate 320 is arranged at the lower part of the frame 100. The movable jaw plate 310 is arranged at the lower part of the frame 100. The second eccentric shaft 330 is rotatably connected to the top end of the movable jaw plate 310. The second eccentric shaft 330 can rotate around its axis. One end of the second movable restraint 340 is rotatably arranged on the frame 100, and the other end of the second movable restraint 340 is rotatably connected to the lower end of the movable jaw plate 310.

[0041] During use, the second eccentric shaft 330 rotates around its own axis. Under the rotation of the second eccentric shaft 330, the movable jaw plate 310 approaches or moves away from the fixed jaw plate 320 periodically, thereby reducing or increasing the distance between the movable jaw plate 310 and the fixed jaw plate 320, and realizing the further crushing of the concrete block.

[0042] It should also be supplemented and explained that the second movable restraint member 340 includes a second toggle plate 341, a second fixed seat 342, a second pull rod 343, a second limiting plate 344, a second fixing plate 345 and a second spring 346.

[0045] In this embodiment, a transmission assembly 500 is arranged between the first eccentric shaft 270 and the second eccentric shaft 330.
