Construction waste includes a large amount of waste building concrete, waste bricks, etc. These waste materials can be reused. Moreover, long-term stacking will cause certain pollution and affect the urban beauty. When transporting relevant construction waste and building waste, large transport vehicles are generally used for transportation. However, when transporting large pieces of building concrete and waste bricks, if they are not broken, it will cause waste of the loading space of the transport vehicle. Therefore, crushing large pieces of construction waste can effectively improve the transportation efficiency of construction waste and the space utilization rate of transport vehicles.

[0003] For example, the patent network discloses a waste recycling and crushing device for building construction (publication number: CN219273150U). The separation plate of this device is directly fixed on the device and cannot be disassembled, resulting in that this device can only separate impurities of one size. If impurities of other sizes need to be separated, other models of crushing devices have to be used, which is very inconvenient. Therefore, those skilled in the art have proposed a building construction waste crushing device. Content of the Utility Model

A crushing mechanism is arranged above the push plate mechanism inside the box body 1. The filtering mechanism includes a slot 2 opened on the side of the box body 1. Two installation slots communicating with the slot 2 are correspondingly opened on the inner wall of the box body 1. An inclined filter plate 3 adapted to them is jointly arranged in the two installation slots. A cavity 4 is opened above the slot 2 in the side wall of the box body 1. A limiting plate 5 is slidably arranged in each cavity 4. A spring 6 is arranged above the limiting plate 5 in the cavity 4. A strip-shaped slot 7 communicating with it is opened on the side of the box body 1 on one side of the cavity 4. A dial block 8 extending to the outside through the strip-shaped slot 7 is installed on the side surface of the limiting plate 5. A clamping slot 9 is opened on the upper surface of the filter plate 3 directly below the limiting plate 5. A clamping member 10 extending into the clamping slot 9 is installed on the lower surface of the limiting plate 5. A handle 11 is installed on the side surface of the filter plate 3. When in use, when replacing the filter plate 3, pull up the dial block 8 to drive the limiting plate 5 to move upward. While the upward moving limiting plate 5 compresses the spring 6, it drives the clamping member 10 to move out of the clamping slot 9, thus releasing the fixation of the filter plate 3. Then, pull out the filter plate 3 from the slot 2. Then, insert the filter plates 3 with different-sized filter holes into the installation slots from the slot 2, and align its clamping slot 9 with the clamping member 10. Then, release the dial block 8, and the spring 6 rebounds to drive the clamping member 10 to snap into the clamping slot 9 to re-fix the filter plate 3, and the replacement is completed.

[0022] Please refer to Figures 1-3 , the push plate mechanism includes a moving seat 12 installed on the side of the box body 1 above the filter plate 3 and having the same inclination as the filter plate 3. A moving slot 13 is opened on the upper surface of the moving seat 12. A first motor 14 is installed at one end of the moving seat 12. The driving end of the first motor 14 extends into the moving slot 13 and is installed with a screw rod 15 whose end is rotatably connected to the inner wall of the moving slot 13. A threaded seat 16 is arranged on the screw rod 15. A round rod 17 extending into the box body 1 is installed above the screw rod 15 on the side surface of the threaded seat 16. A push plate 18 is installed at the end of the round rod 17 extending into the box body 1 above the filter plate 3. When construction waste falls on the filter plate 3 and cannot slide away from it, stop crushing. Then, the first motor 14 runs to drive the screw rod 15 to rotate, thereby driving the threaded seat 16 to move. The moving threaded seat 16 drives the push plate 18 to move in the direction of the first outlet 23 through the round rod 17. The moving push plate 18 pushes the construction waste that cannot slide away on the filter plate 3, and then pushes it out from the first outlet 23, thus playing a role in cleaning the surface of the filter plate 3. Then, the first motor 14 drives the screw rod 15 to reverse and drives the push plate 18 to return to its original position through the above operation.

[0023] Please refer to Figures 1-3 and Figure 5, the crushing mechanism includes a group of crushing rollers 19 rotatably installed on the inner wall of the box body 1 and above the push plate 18. On the other side surface of the box body 1, a second motor 20 is installed on one side of a crushing roller 19. The driving end of the second motor 20 extends into the box body 1 and is fixedly connected to the end of the aligned crushing roller 19. The other ends of the two crushing rollers 19 extend outside the box body 1 and are installed with meshing gears 21. On the inner wall of the box body 1, two inclined guide plates 22 are installed directly above the two crushing rollers 19. During use, the operating second motor 20 drives the connected crushing roller 19 to rotate, and then drives the other crushing roller 19 to rotate in the opposite direction through the two meshing gears 21, so that the two crushing rollers 19 rotate towards each other. The construction waste is fed into the box body 1 from the upper port of the box body 1. After being guided by the two guide plates 22, the construction waste passes between the two crushing rollers 19 rotating towards each other, and the construction waste passing through the two crushing rollers 19 is used for crushing.

[0024] Please refer to Figures 1-3 , a first outlet 23 is opened on the front surface of the box body 1 at the lowest edge of the filter plate 3. A bottom plate 24 with the same inclination as the filter plate 3 is installed below the filter plate 3 inside the box body 1. A second outlet 25 is opened on the front surface of the box body 1 at the lowest edge of the bottom plate 24. During use, the crushed garbage falls on the filter plate 3, and the filter plate 3 is used to filter it. The construction waste that meets the standard is blocked by the filter plate 3 and then slides out from the first outlet 23 for collection, while the overly crushed small particle impurities of other soil types fall on the bottom plate 24 and then are discharged from the second outlet 25 for collection.

[0025] The working principle of the present utility model: The operating second motor 20 drives the connected crushing roller 19 to rotate, and then drives the other crushing roller 19 to rotate in the opposite direction through the two meshing gears 21, so that the two crushing rollers 19 rotate towards each other. The construction waste is fed into the box body 1 from the upper port of the box body 1. After being guided by the two guide plates 22, the construction waste passes between the two crushing rollers 19 rotating towards each other, and the construction waste passing through the two crushing rollers 19 is used for crushing. The crushed garbage falls on the filter plate 3, and the filter plate 3 is used to filter it. The construction waste that meets the standard is blocked by the filter plate 3 and then slides out from the first outlet 23 for collection, while the overly crushed small particle impurities of other soil types fall on the bottom plate 24 and then are discharged from the second outlet 25 for collection;

[0026] If construction waste falls on the filter plate 3 and cannot slide away from it, the crushing stops. Then, the first motor 14 operates to drive the screw 15 to rotate, thereby driving the threaded seat 16 to move. The moving threaded seat 16 drives the push plate 18 to move towards the first outlet 23 through the round rod 17. The moving push plate 18 pushes the construction waste that cannot slide away on the filter plate 3, and then pushes it out from the first outlet 23, thus playing a role in cleaning the surface of the filter plate 3. Then, the first motor 14 drives the screw 15 to reverse and drives the push plate 18 to restore its position through the above operations, so that the device can continue to operate;

[0027] When replacing the filter plate 3, the upper shifting block 8 is used to drive the limiting plate 5 to move upward. When the upward moving limiting plate 5 compresses the spring 6, it drives the clamping member 10 to move out of the card slot 9, and the fixation of the filter plate 3 can be released. Then, the filter plate 3 is pulled out from the slot 2. Then, the filter plate 3 with different-sized filter holes is inserted into the installation slot from the slot 2, and the card slot 9 is aligned with the clamping member 10. Then, the block 8 is released, and the spring 6 rebounds to drive the clamping member 10 to snap into the card slot 9 to fix the filter plate 3 again, and the replacement is completed.
