Description

Technical Field

[0001] The present invention relates to the technical field of construction waste treatment, and particularly to a method for recycling construction waste. Background Art

[0002] Construction waste can be divided into muck, concrete blocks, stones, brick and tile fragments, waste mortar, slurry, asphalt blocks, waste plastics, waste metals, waste bamboo and wood, etc. With the acceleration of the industrialization and urbanization processes, the construction industry has also developed rapidly, and the accompanying construction waste has increased day by day. Large stones are one of the construction wastes that can be recycled and utilized. After being recycled and processed, they can be reapplied to improve the performance of subsequent artificial stones. However, due to their irregular shapes, large stones are also a part of construction waste that is difficult to handle. But large stones often need to be recycled through a recycling device when being recycled.

[0003] When the existing stone recycling device is in use, it often directly recycles large stones, that is, transports the large stones into the recycling device. When there are too many large stones recycled in the recycling device, due to the irregular shapes of the large stones, the gaps between multiple large stones will be too large due to their shapes, resulting in low utilization rate of the recycling space of the recycling device. Summary of the Invention

[0004] (1) Object of the Invention

[0005] To solve the technical problems in the background art, the present invention proposes a method for recycling construction waste. This method can effectively complete the recycling of stones, and when recycling stones, it can first perform a crushing operation on the stones, thereby effectively preventing the situation that when too large stones are recycled and multiple large stones are in the collection box, there will be large gaps between multiple stones, resulting in insufficient utilization rate of the space in the collection box. And after performing the crushing operation on the stones, this method can directly collect them. Moreover, when crushing the stones, it crushes the stones at their original positions without first transporting the stones and then crushing them. And this method does not need to contact other crushing tools when crushing the stones, and after crushing, it can directly transport the crushed stones, thereby effectively improving the working efficiency of this method.

[0041] In the description of the invention, it should be noted that unless otherwise clearly defined and limited, terms such as "installed", "equipped with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, such as welding, riveting, bonding, etc., or a detachable connection, such as screw connection, key connection, pin connection, etc., or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0042] As Figures 1-5 shown, a construction waste recycling method proposed by the present invention specifically includes the following steps:

[0043] S1. Move the collection box 1 above the stones, block the stones by moving the shielding box 4 below the collection box 1, and crush the stones by a crusher.

[0044] S2. Move the inclined shovel plate 6 into the shielding box 4, shovel the crushed stones in the shielding box 4 by the inclined shovel plate 6, and move upward to the shovel plate 6 to move the stones on the shovel plate 6 into the fixed cylinder 17.

[0045] S3. Move the stones in the fixed cylinder 17 into the collection box 1 for collection by a screw conveyor.

[0046] A crusher is provided at the bottom end of the collection box 1. A shielding box 4 that is vertically penetrated is arranged at intervals below the collection box 1. A first driving component for driving the shielding box 4 to move in the vertical direction is provided on the collection box 1. The crusher is located in the shielding box 4. An inclined shovel plate 6 is slidably arranged in the shielding box 4 and is inclined downward. A second driving component for driving the shovel plate 6 to extend into or out of the shielding box 6 is provided on the shielding box 4. A second driving component for driving the shovel plate 6 to move in the vertical direction is provided on the shielding box 4. A hole for the crushing end of the crusher to pass through is provided on the shovel plate 6. A fixed cylinder 17 is provided at the bottom end of the collection box 1. The upper end of the fixed cylinder 17 extends into the collection box 1 and an outlet component is rotatably arranged. A screw 18 is arranged in the fixed cylinder 17. A feed inlet is provided on the fixed cylinder 17. A discharge outlet is provided on the shielding box 4. The shielding box 4 can be moved to make the discharge outlet communicate with the feed inlet. And the second driving component and the third driving component can drive the lowest end of the shovel plate 6 to move to the same horizontal line as the lowest end of the feed inlet.

[0047] In the present invention, when this method needs to be used, it can be moved above the stones to be recycled. The first driving component drives the shielding box 4 to move downward. When the shielding box 4 moves downward to shield the stones, the shovel plate 6 is driven to move downward when the shielding box 4 moves downward. After the shovel plate 6 moves downward and disengages from the contact with the crusher 5, the second driving component drives the shovel plate 6 to move out of the shielding box 4, and the crusher 5 is used to complete the crushing of the broken pieces. Moreover, under the shielding of the inner wall of the shielding box 4, it can effectively prevent the stones from splashing during crushing, thereby effectively improving the safety of using this method. After the stones are crushed, the second driving component drives the shovel plate 6 to extend into the shielding box 4. Since the shovel plate 6 is inclined, the shovel plate 6 can scoop up the crushed stones broken by the crusher 5 onto the shovel plate 6 when moving. And under the action of the inner wall of the shielding box 4, the crushed stones on the shovel plate 6 can be kept on the shovel plate 6 at all times. Then, the third driving component drives the shovel plate 6 to move upward. When the shovel plate 6 moves upward, it drives the crushed stones on it to move upward. When the shovel plate 6 moves to the feeding port and the discharging port, the inner wall of the shielding box 4 cannot shield the crushed stones on the shovel plate 6. Therefore, the crushed stones on the shovel plate 6 enter the fixed cylinder 17 through the discharging port and the feeding port under the action of gravity, and are conveyed by the auger 18 to make the crushed stones enter above the collection box 1, thus completing the recycling of the crushed stones. This method can effectively complete the recycling of the stones, and when recycling the stones, it can first perform a crushing operation on the stones, thereby effectively preventing the situation that because the recycled stones are too large, when multiple large stones are in the collection box 1, there will be large gaps between the multiple stones, resulting in insufficient space utilization rate in the collection box 1. And after this method performs a crushing operation on the stones, it can directly collect them. Moreover, when crushing the stones, this method crushes the stones at their original positions without first transporting the stones and then crushing them. And this method does not need to contact other crushing tools when crushing the stones, and can directly transport the crushed stones after crushing, thereby effectively improving the working efficiency of this method.

[0048] In an alternative embodiment, the first driving component includes a first motor 7, a first transmission block 8, and a first screw rod 9. Two first transmission blocks 8 are respectively arranged at both ends of the shielding box 4. Both of the two first transmission blocks 8 are provided with first threaded through holes. The first motor 7 is located above the first transmission block 8 and is connected to the bottom end of the collection box 1. The first screw rod 9 is rotatably connected to the collection box 1 through a mounting frame 10. One end of the first screw rod 9 is coaxially connected to the output shaft of the first motor 7, and the other end of the first screw rod 9 passes through the first threaded through hole and is threadedly connected to the first transmission block 8;

[0049] The specific steps for moving the shielding box 4 are as follows:

[0050] The first motor 7 drives the first screw rod 9 to rotate. The rotation of the first screw rod 9 drives the first transmission block 8 to move through screw thread transmission, and the movement of the first transmission block 8 drives the shielding box 4 to move.

[0051] It should be noted that there is a through hole on the mounting frame 10. The first screw rod 9 passes through the through hole and is rotatably connected to the mounting frame 10. The first motor 7 can effectively drive the first screw rod 9 to rotate. The rotation of the first screw rod 9 drives the first transmission block 8 threadedly connected thereto to move, thereby driving the shielding box 4 to move in the up and down direction. When the shielding box 4 is at the uppermost position, it can effectively shield the crusher 5, thereby effectively preventing the stones splashing on the road during the movement of the method from damaging the crusher 5.

[0052] In an alternative embodiment, the second driving mechanism includes a limiting plate 11, a second motor 12 and a second screw rod 13. The limiting plate 11 is arranged in parallel with the shovel plate 6 and is slidably connected to one end of the shielding box 4 away from the fixed cylinder 17. There is a first through hole on the shielding box 4 for the shovel plate 6 to slide through. One end of the shovel plate 6 facing the first through hole is provided with a first threaded blind hole. The shovel plate 6 can extend out of the first through hole and is slidably attached to the upper end of the limiting plate 11. The second motor 12 is connected to one end of the limiting plate 11 away from the shielding box 4. One end of the second screw rod 13 is coaxially connected to the output shaft of the second motor 12. The second screw rod 13 is rotatably arranged on the limiting plate 11 through a first fixing plate. The other end of the second screw rod 13 passes through the first through hole and extends into the shielding box 4. The other end of the second screw rod 13 extends into the first threaded blind hole and is threadedly connected to the shovel plate 6. The limiting plate 11 is in transmission connection with the third driving mechanism;

[0053] Moving the inclined shovel plate 6 to the shielding box 4 specifically includes the following steps:

[0054] The second motor 12 drives the second threaded rod to rotate. The rotation of the second screw rod 13 drives the shovel plate 6 threadedly connected thereto to move. The shovel plate 6 moves out of the first through hole and enters the shielding box 4.

[0055] It should be noted that the second motor 12 drives the second screw rod 13 to rotate. The rotation of the second screw rod 13 can effectively drive the shovel plate 6 threadedly connected thereto to slide. When the second motor 12 is driving, the shovel plate 6 always remains in a straight line with the first through hole, thus not affecting the movement of the shovel plate 6. There is a through hole on the first fixing plate 23. The second screw rod 13 passes through the through hole and is rotatably connected to the first fixing plate 23, thereby effectively improving the rotation stability of the second screw rod 13.

[0056] In an alternative embodiment, the third driving mechanism includes a third motor 14 and a third screw 15. A strip-shaped through-hole perpendicular to and communicating with the first through-hole is provided on the shielding box 4. The strip-shaped through-hole is located above the first through-hole. Second transmission blocks 16 are provided at both ends of the limiting plate 11. The second transmission blocks 16 are slidably connected to the shielding box 4 and are provided with second threaded through-holes. The third motor 14 is located above the second transmission blocks 16 and is connected to the outer end of the shielding box 4. The third screw 15 is rotatably connected to the shielding box 4 through a second fixing plate. One end of the third screw 15 is coaxially connected to the output shaft of the third motor 14, and the other end of the third screw 15 passes through the second transmission block 16 and is threadedly connected thereto;

[0057] The upward movement to the shovel plate 6 specifically includes the following steps:

[0058] The third motor 14 drives the third screw 15 to rotate. The rotation of the third screw 15 drives the second transmission block 16 threadedly connected thereto to move. The movement of the second transmission block 16 drives the limiting plate 11 connected thereto to move. The movement of the limiting plate 11 drives the shovel plate 6 to move.

[0059] It should be noted that the third motor 14 drives the third screw 15 to rotate. The rotation of the third screw 15 drives the second transmission block 16 threadedly connected thereto to move, thereby effectively driving the limiting plate 11 to move upward. When the limiting plate 11 moves upward, the shovel plate 6 is located inside the shielding box 4 and slides on its inner wall, so that it will not affect the movement of the limiting plate 11. And the strip-shaped through-hole can also be used for the movement of the third screw 15. A through-hole is provided on the second fixing plate 24, and the third screw 15 passes through the through-hole and is rotatably connected to the second fixing plate 24.

[0060] In an alternative embodiment, the discharging assembly includes a mounting ring 19 and a slideway 20. The mounting ring 19 is coaxially arranged with the upper end of the fixed cylinder 17 and is rotatably connected to the fixed cylinder 17. A first opening is provided on the mounting ring 19. The first opening is connected to and communicates with one end of the downwardly inclined slideway 20. A fixing unit for fixing the mounting ring 19 and the fixed cylinder 17 is provided on the mounting ring 19;

[0061] The movement of the stone material into the collection box 1 specifically includes the following steps:

[0062] The dragon 18 is used to move the stone in the fixed cylinder 17 upward, and the stone moves into the mounting ring 19, and moves into the slide 20 through the first opening on the mounting ring 19, and the stone is transported to the collecting box 1 through the slide 20. The mounting ring 19 is rotated to drive the slide 20 to rotate, so as to facilitate the stone transportation.

[0063] It should be noted that the dragon 18 in the fixed cylinder 17 through the first opening of the mounting ring 19 can transport the crushed stone from the fixed cylinder 17 to the mounting ring 19, and slide it into the collecting box 1 through the first opening and the slide 20. In addition, the method can also rotate the mounting ring 19, thereby changing the position of the first opening and the slide 20, so as to adjust the discharge direction of the slide 20, thereby effectively avoiding the accumulation of crushed stone at the same position in the collecting box 1.

[0064] In an optional embodiment, the fixing unit includes a connecting plate 21 and a bolt 22, the connecting plate 21 is connected to the end of the mounting ring 19 away from the slideway 20, the lower end of the connecting plate 21 is slidably arranged in contact with the fixing cylinder 17, a third threaded through hole is provided on the connecting plate 21, the bolt 22 is threadedly arranged in the third threaded through hole, and the bolt 22 can be moved to abut against the outer end of the fixing cylinder 17;

[0065] Fixing the mounting ring 19 specifically includes the following steps:

[0066] The mounting ring 19 is moved to a suitable position, and the mounting ring 19 drives the slideway 20 to move to a suitable position. The bolt 22 is rotated, and the bolt 22 is rotated until it moves to abut against the fixing tube 17 .

[0067] It should be noted that when the mounting ring 19 needs to be fixed, the rotation of the mounting ring 19 drives the connecting plate 21 to rotate, so that when the mounting ring 19 is rotated to the appropriate position, the connecting plate 21 and the fixing tube 17 can be effectively fixed by tightening the bolts 22, thereby completing the fixation of the mounting ring 19 and the fixing tube 17.

[0068] In an optional embodiment, a plurality of supporting legs 2 are provided at the bottom end of the collection box 1, and universal wheels 3 are provided below the plurality of supporting legs 2;

[0069] Moving the collection box 1 specifically includes the following steps:

[0070] By pushing the collection box 1, the collection box 1 moves, driving the support legs 2 and the universal wheels 3 to move, and the universal wheels 3 reduce the friction between the collection box 1 and the ground when it moves.

[0071] It should be noted that, by means of the supporting legs 2 and the universal wheels 3, the method can be conveniently moved to complete the recovery operation.
