A recycling device for road construction

Abstract

The present invention relates to the field of separation technology, and in particular to a recycling and reuse device for road construction, comprising a frame, a separation component, a control module, and a crushing component. The separation component is arranged at the upper portion of the frame. The separation component is used to separate a reinforced concrete slab into steel bars and concrete blocks. The separation component comprises a fixed shaft, a rotating column, an electromagnet, and a movable clamping plate. The fixed shaft is arranged at the upper portion of the frame. The present invention is provided with a separation component. Before the reinforced concrete slab enters the crushing component, the separation component first crushes the reinforced concrete slab into steel bars and concrete blocks. At this time, concrete blocks smaller than the second crushing protrusions roll into the crushing component under the action of their own gravity. The steel bars are longer in length and are therefore sandwiched between the second crushing protrusions and cannot fall. This separates the steel bars from the second crushing protrusions, preventing the steel bars from entering the crushing component together with the concrete blocks, and preventing blockage inside the crushing component.

Description

Technical Field

[0001] The present invention relates to the field of separation technology, in particular to a recycling device for road construction. Background Art

[0002] During road construction, it's sometimes necessary to renovate a section of the road. Specifically, a road cutter is used to dismantle the old road surface into sections, breaking them into multiple reinforced concrete slabs. These slabs are then removed from the ground one by one. To recycle the removed slabs, jaw crushers are typically used to break them up, separating the concrete blocks from the steel bars.

[0003] Since the steel bars are very long and difficult to be cut by the jaw crusher, they are easily blocked in the jaw crusher during the crushing process, making it impossible to separate the concrete blocks and steel bars, which in turn causes the jaw crusher to be blocked.

After the movable clamping plate reaches a preset working time, the control module controls the electromagnet to be energized for a set time. At this time, the electromagnet generates magnetism to attract the steel bars to the crushing plane facing the movable clamping plate.

In this way, the steel bars and the second crushing protrusion are separated, preventing the steel bars from entering the crushing component together with the concrete blocks, thereby preventing blockage inside the crushing component.

[0044] like Figures 1 to 11As shown, a recycling and reuse device for road construction is used to recycle reinforced concrete slabs. The recycling and reuse 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 at the upper part of the frame 100. The separation component 200 is used to separate the reinforced concrete slabs 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 at the upper part of the frame 100, and the axis of the fixed shaft 210 is arranged at an angle to the horizontal plane. The electromagnet 230 is arranged at a downward position inside the fixed shaft 210. The rotating column 220 is rotatably arranged on the outer periphery of the fixed shaft 210, and the rotating column 220 can rotate around its axis. A plurality of crushing planes 221 are equidistantly spaced on the outer periphery of the rotating column 220, and a plurality of first crushing planes 221 are evenly arranged on the crushing planes 221. The protrusion 222 and the movable clamping plate 240 are inclinedly arranged on the frame 100, and the movable clamping plate 240 is located below the rotating column 220. A plurality of second crushing protrusions 241 are evenly arranged on the upper surface of the movable clamping plate 240. The first crushing protrusion 222 and the second crushing protrusion 241 are staggered with each other, and the movable clamping plate 240 can reciprocate close to or away from the rotating column 220. The control module is used to control the electromagnet 230 to be energized intermittently, and the control module is configured to control the electromagnet 230 to be energized for a set period of time after the movable clamping plate 240 reciprocates close to or away from the rotating column 220 for a preset period of time 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 at a preset angle during the process of the electromagnet 230 being energized for a set period of time. The crushing assembly 300 is arranged on the frame 100 and is located below the separation assembly 200, for crushing the separated concrete blocks.

[0045] When in use, the staff puts 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 is reduced. Under the action of the second crushing protrusion 241 and the first crushing protrusion 222, the reinforced concrete slab is compressed and crushed into steel bars and concrete blocks. When the movable clamping plate 240 is away from the rotating column 220, the upper surface of the movable clamping plate 240 and the crushing plane 221 of the rotating column 220 are 21 increases, and at this time, the concrete blocks that are smaller than the distance between the second crushing protrusions 241 roll into the crushing assembly 300 under the action of their own gravity, so that the concrete blocks can be further crushed into particles of the desired size by the crushing assembly 300. The steel bars are clamped between the second crushing protrusions 241 due to their long length and cannot fall. After the movable clamping plate 240 approaches or moves away from the rotating column 220 for a preset time and stops, the control module controls the electromagnet 230 to be energized for a set time. At this time, the electromagnet 230 generates magnetism to attract the steel bars to the crushing plane 221 facing the movable clamping plate 240. During the period of time when the electromagnet 230 is energized for the set time, the steel bars are attracted to the crushing plane 221 facing the movable clamping plate 240. During the process, the rotating column 220 rotates a preset angle so that the crushing plane 221 with the steel bar attracted is rotated to the upper surface away from the movable clamping plate 240, and the crushing plane 221 without the steel bar attracted is rotated to face the movable clamping plate 240. Next, the electromagnet 230 is powered off. At this time, the steel bar is no longer attracted to the rotating column 220, and the steel bar falls to both sides of the frame 100 under its own gravity. In this way, the steel bar and the second crushing protrusion 241 are separated, preventing the steel bar from entering the crushing assembly 300 together with the concrete block, preventing the crushing assembly 300 from being blocked. Next, the movable clamping plate 240 continues to reciprocate close to or away from the rotating column 220 to prevent the crushing The time is set, and the reinforced concrete is continued to be 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 towards or away from the rotating column 220 reaches the preset time, the movable clamping plate 240 stops moving, and then the electromagnet 230 is energized for a set time. During the process of the electromagnet 230 being energized for a set time, the rotating column 220 rotates by a preset angle so that the crushing plane 221 with the steel bars absorbed is rotated to the upper surface away from the movable clamping plate 240, and the crushing plane 221 without the steel bars absorbed is rotated to the movable clamping plate 240. Next, the above steps are repeated to complete the crushing of the reinforced concrete in the entire batch.

[0046] It should be supplemented that, in order to make the steel bars sucked on the crushing plane 221 fall more easily, specifically, the length of the first crushing protrusion 222 can be made smaller than the length of the second crushing protrusion 241 .

[0047] It should be added that, taking the example of six crushing planes 221 provided on the outer circumference of the rotating column 220 , the preset angle of each rotation of the rotating column 220 is sixty degrees.

[0048] In this embodiment, the upper surface of the movable clamping plate 240 is also elastically connected to the screening plate 250, and a plurality of screening holes 251 are provided on the surface of the screening plate 250. The surface of the screening plate 250 is also provided with a plurality of through holes 252. The diameter of the through holes 252 is adapted to the size of the second crushing protrusions 241, and the plurality of through holes 252 correspond one-to-one to the plurality of second crushing protrusions 241 and are slidably fitted.

[0049] The screening holes 251 are provided to separate the concrete powder and concrete blocks generated during the crushing process, 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, thereby achieving the separation of the concrete powder and the concrete blocks, and preventing the concrete entering the crushing assembly 300 from having too large a particle size difference, which would cause the particle size difference of the concrete blocks discharged from the crushing assembly 300 to further increase.

[0050] It is understandable that the through hole 252 is provided so that when the movable clamping plate 240 approaches the rotating column 220 , the second crushing protrusion 241 can extend from the through hole 252 and crush the reinforced concrete slab.

[0051] In this embodiment, a material guiding inclined surface 242 is formed on the upper surface of the movable clamping plate 240 , and the material guiding inclined surface 242 is inclined downward from the center of the movable clamping plate 240 in the width direction to the left and right sides thereof.

[0052] The guiding slope 242 is provided to guide the concrete powder leaking from the screening plate 250 so that more concrete powder falls from the lower part of the movable clamping plate 240 and near the left and right sides thereof, so as to collect the concrete powder in a centralized manner.

[0053] In this embodiment, baffles 260 are detachably provided on the frame 100 and located on the left and right sides of the movable clamping plate 240 .

[0054] The baffles 260 are provided to prevent concrete blocks from rolling down from the left and right sides of the driven clamping plate 240 during the crushing process, and to prevent concrete powder from falling from the left and right sides of the driven clamping plate 240.

[0055] It should be noted that in order to facilitate feeding 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, the baffle 260 is rotated to expose enough space on the feeding side of the frame 100 to facilitate the staff to feed the reinforced concrete slab between the movable clamping plate 240 and the rotating column 220. After the feeding is completed, the baffle 260 is rotated in the opposite direction to reset the baffle 260.

[0056] In this embodiment, a material receiving box 110 is provided on the frame 100 and below the movable clamping plate 240 . The material receiving box 110 is used to guide the material falling from the movable clamping plate 240 so that the material falling from the movable clamping plate 240 is discharged from the left and right sides of the frame 100 .

[0057] It can be understood that when the concrete powder falls from the lower part of the driven splint 240, the concrete powder easily falls into the inside of the crushing assembly 300 because it is located close to the crushing assembly 300. By providing a receiving box 110 on the frame 100 and below the dynamic splint 240, the concrete powder falling from the driven splint 240 can be received and discharged in an orderly manner from the left and right sides of the frame 100 under the guidance of the receiving box 110.

[0058] In this embodiment, a first drive assembly 400 is provided on the upper part of the frame 100. The first drive assembly 400 includes a first drive motor 410, a gear 420 and a gear ring 430. The first drive 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 drive motor 410, and the gear ring 430 is coaxially arranged at one end of the rotating column 220, and the gear ring 430 and the gear 420 are engaged with each other.

[0059] After the electromagnet 230 is energized, the control module transmits an electrical signal to the first drive motor 410. At this time, the output end of the first drive motor 410 drives the gear 420 to rotate synchronously by a preset angle, and the gear 420 drives the gear ring 430 to rotate by a preset angle. Since the gear 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 with the steel bars absorbed rotates to the upper surface away from the movable clamping plate 240, and the crushing plane 221 without the steel bars absorbed rotates to face the movable clamping plate 240.

[0060] In this embodiment, the separation assembly 200 also includes a first eccentric shaft 270 and a first movable restraint 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 restraint 280 is rotatably provided on the frame 100, and the other end of the first movable restraint 280 is rotatably connected to the lower end of the movable clamping plate 240.

[0061] In order to drive the reciprocating approach to or away from the rotating column 220, specifically, the first eccentric shaft 270 is made to rotate circumferentially. Under the rotation of the first eccentric shaft 270, the dynamic clamping plate 240 periodically approaches or moves away from the rotating column 220, thereby reducing or increasing the distance between the dynamic clamping plate 240 and the rotating column 220, thereby achieving the crushing of the reinforced concrete slab.

[0062] It should also be noted that the first movable restraint 280 includes a first toggle plate 281, a first fixed seat 282, a first pull rod 283, a first limit 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 set 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, and the first limit plate 284 is set At the lower end of the first fixed seat 282, a first limiting hole 2841 is opened on the first limiting plate 284, the diameter of the first limiting hole 2841 is larger than the diameter of the first pull rod 283, and the end of the first pull rod 283 away from the movable clamping plate 240 passes through the first limiting hole 2841, and the first fixed plate 285 is arranged at the end of the first pull rod 283 away from the movable clamping plate 240, and the first spring 286 is sleeved on the outside of 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.

[0063] 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.

[0064] When in 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 periodically approaches or moves away from the fixed jaw plate 320, thereby reducing or increasing the distance between the movable jaw plate 310 and the fixed jaw plate 320, thereby achieving further crushing of the concrete block.

[0065] It should be added that the second movable restraint 340 includes a second toggle plate 341, a second fixed seat 342, a second pull rod 343, a second limiting plate 344, a second fixed plate 345 and a second spring 346. Specifically, the second fixed seat 342 is set on the frame 100, one end of the second toggle plate 341 is hinged on the second fixed seat 342, the other end of the second toggle plate 341 is hinged on the movable jaw 310, one end of the second pull rod 343 is hinged on the movable jaw 310 and is located below the second toggle plate 341, and the second limiting plate 344 is set on the second fixed seat At the lower end of the seat 342, a second limiting hole 3441 is opened on the second limiting plate 344, the diameter of the second limiting hole 3441 is larger than the diameter of the second pull rod 343, and the end of the second pull rod 343 away from the movable jaw plate 310 passes through the second limiting hole 3441, and the second fixed plate 345 is arranged at the end of the second pull rod 343 away from the movable jaw plate 310, and the second spring 346 is sleeved on the outside of the second pull rod 343, and one end of the second spring 346 is fixedly connected to the second fixing plate 345, and the other end of the second spring 346 is fixedly connected to the second limiting plate 344.

[0067] In the working state, the second drive motor is started, and the output shaft of the second drive motor drives the driving pulley to rotate. The driving pulley drives the driven pulley 350 to rotate through the belt, and the driven pulley 350 drives the second eccentric shaft 330 to rotate, thereby causing the second eccentric shaft 330 to rotate circumferentially.

[0068] In this embodiment, a transmission assembly 500 is provided between the first eccentric shaft 270 and the second eccentric shaft 330.
