Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0023] This application discloses a construction waste recycling device. Please refer to [link / reference]. Figures 1-4A construction waste recycling device includes: a crushing box 1, with a feed inlet 2 connected to the top of the crushing box 1; a crushing component 3 disposed at the center of the crushing box 1 for crushing construction waste; a discharge pipe 4 connected to the bottom of the crushing box 1; a screening box 5 connected to the bottom of the discharge pipe 4; a screening component 6 disposed inside the screening box 5 for screening the crushed construction waste; a vibrating motor 9 fixedly connected to the outer wall of one end of the crushing box 1; and a screening component 6 including a screening chamber 601 opened inside the screening box 5, with a support column 6 fixedly connected to the inner wall of the screening chamber 601. 02. A spiral screening mesh 603 is fixedly connected to the outer wall of the support column 602. A spiral guide plate 604 is provided below the spiral screening mesh 603. Both the spiral screening mesh 603 and the spiral guide plate 604 are spiral structures. Under the vibration of the vibrating motor 9, the spiral screening mesh 603 screens the garbage particles, causing small particles to fall onto the spiral guide plate 604. At the same time, the spiral screening mesh 603 and the spiral guide plate 604 guide the garbage particles in a spiral direction, causing the garbage particles to move along the spiral direction under vibration. The spiral guide plate 604 and the support column 602... The outer wall of the screening chamber 601 is fixedly connected to a guide chamber 607. The guide chamber 607 is inclined, and the guide plate 606 is also inclined. The bottom end of the guide plate 606 is in contact with the inner wall of the bottom end of the guide chamber 607 to facilitate the guidance of waste into the coarse material collection frame 7. The bottom end of the screening chamber 601 is connected to a discharge port 605. The screening assembly 6 also includes a guide plate 606 disposed inside the guide chamber 607. The guide plate 606 is fixedly connected to the bottom end of the spiral screen 603. The bottom end of the screening box 5 is slidably connected to a coarse material collection frame 7. The collection frame 7 is connected to the bottom of the guide chamber 607. The other side of the bottom of the screening box 5 is slidably connected to the fine material collection frame 8. The fine material collection frame 8 is connected to the bottom of the discharge port 605. The bottom of the spiral guide plate 604 is located inside the discharge port 605, so that the garbage particles at the bottom of the spiral guide plate 604 can directly enter the fine material collection frame 8 for collection under the influence of gravity when they move to the bottom of the spiral guide plate 604. After collection is completed, the coarse material collection frame 7 and the fine material collection frame 8 are pulled out respectively, and the garbage particles inside the coarse material collection frame 7 and the fine material collection frame 8 are then processed.

[0024] Please see Figure 2 and Figure 3The crushing assembly 3 includes a first motor 301 fixedly connected to the outer wall of one end of the crushing chamber 1, and a first rotating shaft 302 fixedly connected to the output end of the first motor 301. The crushing assembly 3 also includes a first crushing roller 303 fixedly connected to the outer wall of the first rotating shaft 302. The other end of the first rotating shaft 302 passes through the outer wall of the other end of the crushing chamber 1 and is fixedly connected to a first gear 304. The crushing assembly 3 also includes a second rotating shaft 307 rotatably connected to the inner wall of one end of the crushing chamber 1, and a second crushing roller 306 fixedly connected to the outer wall of the second rotating shaft 307. The crushing assembly 3 also includes a gear meshing with the outer wall of the first gear 304. The second gear 305 on the wall meshes with the first gear 304 when the first gear 304 rotates. At this time, the rotation directions of the first gear 304 and the second gear 305 are completely opposite. The second gear 305 drives the second rotating shaft 307 to rotate, and the second rotating shaft 307 drives the second crushing roller 306 to rotate. The second crushing roller 306 rotates in opposite directions to the first crushing roller 303, thereby crushing the garbage particles. The other end of the second rotating shaft 307 passes through the outer wall of the other end of the crushing box 1 and is fixedly connected to the center of the second gear 305.

[0025] Working principle and usage process: The construction waste to be crushed is poured into the crushing box 1 through the feed inlet 2. The first motor 301 is started, and the output end of the first motor 301 drives the first rotating shaft 302 to rotate. The first rotating shaft 302 drives the first crushing roller 303 to rotate, which in turn drives the first gear 304 to rotate. The first gear 304 drives the second gear 305 to mesh and rotate, which in turn drives the second rotating shaft 307 to rotate. The second rotating shaft 307 drives the second crushing roller 306 to rotate, thereby crushing the construction waste through the first crushing roller 303 and the second crushing roller 306. After crushing, the waste particles enter the screening chamber 60 through the discharge pipe 4. Inside the spiral screen 603, small waste particles fall into the upper part of the spiral screen 603. The vibration motor 9 is started, which drives the screen box 5 to rotate. The screen box 5 drives the support column 602 to vibrate, and the support column 602 drives the spiral screen 603 to vibrate and screen. Small waste particles are screened out by the spiral screen 603 and fall into the upper part of the spiral guide plate 604. At the same time, both large and small waste particles move along the spiral direction of the spiral screen 603 and the spiral guide plate 604. When the large waste particles move to the guide cavity 607, they fall into the coarse material collection frame 7 under the guidance of the guide plate 606. When the small waste particles move to the bottom of the spiral guide plate 604, they fall into the fine material collection frame 8 through the discharge port 605 for collection.

[0026] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
