[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Reference Figure 1-4 The present invention provides an embodiment of a construction waste recycling device, comprising a crushing box 3 and a processing table 1. The crushing box 3 is rotatably installed on the top of the processing table 1. The crushing box 3 is used to centrally store reinforced concrete blocks and to crush the reinforced concrete blocks demolished from the construction site in batches into the crushing box 3.
[0031] The crushing plate 8 and the processing table 1 are fixedly installed with a gantry frame 7. The gantry frame 7 is located directly above the crushing box 3, and the top of the gantry frame 7 is fixedly installed with a hydraulic cylinder 5. The power output end of the hydraulic cylinder 5 is fixedly installed with the crushing plate 8. The top of the gantry frame 7 has a through hole that communicates with the inner wall. The power output end of the hydraulic cylinder 5 passes through the through hole and extends into the interior of the gantry frame 7.
[0032] The crushing plate 8 is located directly above the crushing box 3 and is used to crush reinforced concrete blocks. After the reinforced concrete blocks are poured into the crushing box 3, the hydraulic cylinder 5 is activated. The crushing plate 8 moves down into the crushing box 3 along with the power output end of the hydraulic cylinder 5 and continuously applies pressure to the reinforced concrete blocks until they are crushed. Then, the power output end of the hydraulic cylinder 5 is controlled to move up, allowing the crushing plate 8 to move out of the crushing box 3 and separate from the reinforced concrete blocks. By repeating the reciprocating motion of the power output end of the hydraulic cylinder 5, the reinforced concrete blocks can be repeatedly crushed until they are crushed to a certain extent. Then, the crushed reinforced concrete blocks are removed from the crushing box 3, thereby separating the reinforced concrete blocks from the steel. This helps to reduce the cumbersome process of steel recycling and improves the efficiency of steel recycling.
[0033] Furthermore, after the crushed reinforced concrete blocks are removed from the crushing chamber 3, the uncrushed reinforced concrete blocks are poured into the crushing chamber 3, and the hydraulic cylinder 5 is activated again to allow the crushing plate 8 to crush the reinforced concrete blocks again.
[0034] The crushing box 3 has a discharge chute connected to its own internal cavity at one end near the rotating shaft 17. The discharge chute is rotatably installed with a baffle 10 to prevent the reinforced concrete blocks from overflowing. After the reinforced concrete blocks inside the crushing box 3 are crushed, the baffle 10 is rotated to open and close the discharge chute, which is conducive to removing the crushed reinforced concrete blocks from the crushing box 3 through the discharge chute. When the bottom of the crushing box 3 and the top of the processing table 1 are on the same horizontal line, the bottom and sides of the baffle 10 are parallel to the bottom and sides of the inner cavity of the crushing box 3 under its own weight, effectively preventing the reinforced concrete blocks from falling from the discharge chute when they are crushed.
[0035] Furthermore, the bottom of the discharge chute is flush with the bottom of the inner cavity of the crushing box 3, and the width of the discharge chute is the same as the width of the inner cavity of the crushing box 3, so as to prevent some of the crushed reinforced concrete blocks from being blocked by the inner wall of the crushing box 3 and remaining inside the crushing box 3 when they are removed from the inside of the crushing box 3.
[0036] Rotating shaft 17 is fixedly installed on both sides of the crushing box 3. The top two sides of the processing table 1 are symmetrically installed with bearing blocks 4 that are compatible with the rotating shaft 17. The ends of the two rotating shafts 17 away from the crushing box 3 are rotatably connected to the two bearing blocks 4 on the side close to the crushing box 3. When the crushed reinforced concrete block is removed from the inside of the crushing box 3, pressure is applied to the outside of the crushing box 3, so that the crushing box 3 rotates towards the discharge chute with the two rotating shafts 17 as the rotation center. When the crushing box 3 is in an inclined state, the reinforced concrete block inside slides along the bottom of the inner cavity of the crushing box 3 under the action of gravity and applies pressure to the baffle 10 and makes it rotate until the reinforced concrete block inside the crushing box 3 is completely removed and the crushing box 3 is reset.
[0037] Hydraulic cylinder 14, the top of the processing table 1 has a placement groove, and the two sides of hydraulic cylinder 14 are symmetrically mounted with rotating shafts that are rotatably connected to the inner wall of the placement groove. Support blocks 15 are symmetrically mounted on the two sides of the bottom of the crushing box 3. Connecting columns are symmetrically mounted on the power output end of hydraulic cylinder 14. The ends of the two connecting columns away from hydraulic cylinder 14 are rotatably connected to the outer walls of the two support blocks 15 respectively. When hydraulic cylinder 14 is started, the power output end of hydraulic cylinder 14 extends and applies pressure to the two support blocks 15. At this time, the power output end of hydraulic cylinder 14 rotates relative to the two support blocks 15 through the two connecting columns and applies pressure to the bottom of the crushing box 3. At the same time, the other end of hydraulic cylinder 14 rotates around the rotating shaft, thereby applying pressure to the bottom of the crushing box 3 and causing it to rotate through the rotating shaft 17. When hydraulic cylinder 14 retracts, the crushing box 3 returns to its original position.
[0038] Two bearing blocks 4 are provided with mounting holes on the side near the crushing box 3. The outer walls of the two rotating shafts 17 are fixedly fitted with transmission bearings 16. The outer rings of the two transmission bearings 16 are fixedly connected to the inner walls of the two mounting holes respectively. The transmission bearings 16 serve as the connecting parts between the rotating shafts 17 and the bearing blocks 4, which can effectively reduce the resistance generated by the rotation of the rotating shafts 17 and improve the smoothness of the rotation of the crushing box 3.
[0039] Multiple rows of crushing plates 2 are fixedly installed on the side of the crushing plate 8 away from the hydraulic cylinder 5. The crushing plates 2 are set in a trapezoidal structure, and the large end of the crushing plate 2 is fixedly connected to one side of the crushing plate 8. The multiple rows of crushing plates 2 can directly contact the reinforced concrete block and act on its exterior, while reducing the contact area between the reinforced concrete block and the crushing plates 2, thereby increasing the pressure borne by the reinforced concrete block and the crushing rate of the reinforced concrete block.
[0040] The top of the gantry 7 is symmetrically provided with guide holes on both sides. A guide rod 6 is slidably installed in the inner cavity of the guide hole. The bottom of the guide rod 6 passes through the guide hole and is fixedly connected to the top of the crushing plate 8. With the cooperation of the guide rod 6 and the guide hole, the crushing plate 8 can limit its own movement trajectory, prevent the crushing plate 8 from shaking or deviating when moving up and down, and improve the stability of the crushing plate 8 when crushing reinforced concrete blocks.
[0041] Cylinders are fixedly installed on both sides of the crushing box 3 near the bearing block 4. A stop block 9 for limiting the baffle 10 is fixedly installed on the power output end of the cylinder. When the reinforced concrete block is crushed in the crushing box 3, the outer wall of the stop block 9 is in contact with the outer wall of the baffle 10 under the action of the cylinder, which effectively prevents the reinforced concrete block inside the crushing box 3 from impacting the baffle 10 and causing the baffle 10 to shift.
[0042] Furthermore, when the crushing box 3 is tilted, the cylinder is activated to move the power output end of the cylinder away from the baffle 10. At this time, the outer wall of the baffle 10 separates from the stop block 9, which is beneficial to the rotation of the baffle 10. At the same time, after the crushing box 3 is reset, the cylinder is activated again to reset the stop block 9, which is beneficial to limit the position of the baffle 10 again.
[0043] A collection box 11 is movably installed at one end of the processing table 1 near the baffle 10. A filter screen 12 for filtering the crushed reinforced concrete is fixedly installed in the inner cavity of the collection box 11. After the crushing box 3 is tilted, the crushed reinforced concrete inside falls through the discharge chute to the top of the filter screen 12. At this time, the crushed reinforced concrete blocks pass through the filter screen 12 and accumulate at the bottom of the inner cavity of the collection box 11. The steel separated from the reinforced concrete blocks is trapped at the top of the filter screen 12, realizing the separation between the reinforced concrete blocks and the steel, which is conducive to the recovery of the steel at the top of the filter screen 12 by the staff.
[0044] Furthermore, a vibration device for vibrating the filter screen 12 is installed in the inner cavity of the collection box 11. This vibration device is existing technology and is a commonly used technical means by those skilled in the art, so it will not be described in detail again. The filter screen 12 is vibrated continuously to prevent the crushed reinforced concrete from accumulating on the top of the filter screen 12 and reducing the filtration rate.
[0045] The end of the collection box 11 away from the processing table 1 has a collection trough that communicates with its own inner cavity. The collection trough is located directly below the filter screen 12, and a baffle plate 13 is rotatably installed in the inner cavity of the collection trough. When collecting the reinforced concrete at the bottom of the inner cavity of the collection box 11, the baffle plate 13 is rotated to open and close the collection trough, so that the reinforced concrete blocks accumulated at the bottom of the inner cavity of the collection box 11 can be cleaned in a concentrated manner through the collection trough.
[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
