Description

Technical Field

[0001] This utility model relates to the field of concrete crushing technology, and in particular to a crushing device for concrete waste. Background Technology

[0002] With the increasing expansion of infrastructure construction in my country, the use of concrete is becoming more and more widespread. However, the large-scale use of concrete also generates a lot of construction waste. Construction waste not only pollutes the surrounding environment but also wastes resources. The current treatment of construction waste usually involves crushing it into fine materials for recycling, so that it can be processed and utilized later.

[0003] According to the description in the concrete crushing device published on the patent website (authorization announcement number: CN 218516791 U), "This utility model discloses a concrete crushing device, which relates to the field of concrete crushing technology. It includes a platform, with a jaw crusher fixedly connected to the top of the platform. A platform is installed at the top inside the platform, and an auxiliary component is installed at the top of the platform. A cleaning component is installed at the top of the platform. The auxiliary component includes a first electric push rod, the bottom end of which is fixed to the top of the platform. Through the setting of the auxiliary component and the cleaning component, this utility model addresses the issue of excessively long steel wires getting stuck in the grooves of the jaw plates in the jaw crusher, while the bottom end is located at the outlet end of the jaw crusher. The auxiliary component can clean these steel wires while the jaw crusher is running. When the jaw crusher stops running, the cleaning component will remove the steel wires and debris completely stuck in the grooves, thus improving the crushing efficiency of the jaw crusher."

[0004] Regarding the above description, the applicant believes the following problems exist: When concrete is poured into the jaw crusher, the jaw crusher starts working, and the jaw plates begin to move. The jaw crusher causes the movable jaw plates to begin cyclical motion, crushing the concrete. This results in some small-sized concrete and some wire rebar getting stuck in the grooves of the jaw plates. The auxiliary components can clean these wire rebars while the jaw crusher is running. When the jaw crusher stops running, the cleaning components will remove all the wire rebar and debris stuck in the grooves, improving the crushing efficiency of the jaw crusher. However, the concrete waste crushed by this device is of varying sizes, making it inconvenient for later processing and utilization, thus its practicality is low. Utility Model Content

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please see Figures 1-4This utility model provides an embodiment of a concrete waste crushing device, including a device housing 1, a device housing 3 501, and a magnetic assembly. A support column 2 is fixedly connected to the bottom of the device housing 1, and a jaw crusher 3 is fixedly connected to the top of the device housing 1. A conveying device 6 is installed inside the device housing 1. The device housing 3 501 is located at the bottom of the device housing 1, and the magnetic assembly is located at the top of the device housing 1. A filter screen 504 is fixedly connected inside the device housing 3 501, and a discharge port 2 506 is fixedly connected to the top of the filter screen 504. A filter screen 2 505 is fixedly connected inside the device housing 3 501, and a discharge port 3 507 is fixedly connected to the top of the filter screen 2 505. An outlet 508 is fixedly connected inside the outer casing 3 501. A connecting block 503 is rotatably connected to the outside of the outer casing 3 501. A fixing plate 512 is rotatably connected inside the connecting block 503. A support column 2 502 is fixedly connected to the outside of the fixing plate 512. A motor 2 509 is fixedly connected to the bottom of the fixing plate 512. An eccentric shaft 511 is fixedly connected to the output end of the motor 2 509. A movable plate 510 is fixedly connected to the outer end of the eccentric shaft 511 away from the motor 2 509. When the motor 2 509 is started, the eccentric shaft 511 begins to rotate. The eccentric shaft 511 drives the movable plate 510 to rotate. The movable plate 510 drives the connecting block 503 to rotate. The connecting block 503 causes the outer casing 3 501 to vibrate, and then the crushed concrete waste falls into... Within the outer casing 501, smaller concrete waste particles fall from the first filter screen 504 onto the second filter screen 505 due to vibration. Subsequently, even smaller particles fall onto the bottom surface of the outer casing 501. The vibration of the outer casing 501 causes all the concrete waste to gradually move towards the discharge outlet, eventually being discharged from each outlet. The connecting block 503 and the movable plate 510 have corresponding through holes. The outer casing 501 is rotatably connected to the through holes in the connecting block 503. Because the connecting block 503 and the movable plate 510 have corresponding through holes, and the outer casing 501 is rotatably connected to the through holes in the connecting block 503, it facilitates the movable plate 510 driving the connecting block 503 to rotate. The device housing 3 501 can vibrate; the filter screen plate 1 504 has larger holes, which can screen out smaller concrete waste, while the filter screen plate 2 505 has smaller holes, which can screen out even smaller concrete waste. Because the filter screen plate 1 504 has larger holes and the filter screen plate 2 505 has smaller holes, concrete waste of different sizes can be screened on different screen plates and the bottom surface of the device housing 3 501, so that the concrete waste can be classified according to size; four sets of support columns 2 502 are provided, and the four sets of support columns 2 502 are evenly distributed on the outside of the fixed plate 512, so that the fixed plate 512 is supported on the ground.

[0021] Please see Figure 4 In this embodiment, the second outer casing 402 is fixedly connected to the top of the transport device 6. A motor 401 is fixedly connected to the outside of the second outer casing 402. A roller 404 is fixedly connected to the output end of the motor 401. A transport belt 406 is driven to the outside of the roller 404. A protrusion 408 is fixedly connected to the outside of the transport belt 406. A roller 405 is driven to the outer end of the transport belt 406 away from the roller 404. A powerful magnet 4 is fixedly connected inside the second outer casing 402. 09. A discharge port 403 is fixedly connected to the bottom of the outer casing 402. A soft scraper 407 is fixedly connected inside the outer casing 402. By starting the motor 401, the roller 404 starts to rotate. Then, the roller 404 drives the conveyor belt 406, which in turn drives the roller 405 to rotate. The crushed concrete waste is then transported by the conveyor device 6 to the bottom of the magnet assembly. The iron in the crushed concrete waste is then attracted by the strong magnet 409, thus the iron is... The iron is adsorbed onto the surface of the conveyor belt 406, and then pushed above the discharge port 403 by the protrusion 408. Because the iron is far from the strong magnet 409, it loses its attraction and is scraped by the soft scraper 407, thus falling into the discharge port 403. The device housing 402 and roller 405 have corresponding through holes. Roller 405 is rotatably connected to the through hole in the device housing 402. Because the device housing 402 and roller 405 have corresponding through holes and roller 405 rotate... The roller 405 is connected to the through hole in the second housing 402, which facilitates the transmission of the conveyor belt 406. The second housing 402 and the roller 404 are provided with through holes at corresponding positions. The roller 404 is rotatably connected to the through hole in the second housing 402. Because the second housing 402 and the roller 404 are provided with through holes at corresponding positions and the roller 404 is rotatably connected to the through hole in the second housing 402, the roller 404 can be rotated by the motor 401.

[0022] During operation, concrete waste is fed into the jaw crusher 3. The crushed concrete waste falls onto the conveyor device 6, which then transports it to the bottom of the magnetic component. The iron in the crushed concrete waste is then attracted by the strong magnet 409, adhering to the surface of the conveyor belt 406. The iron is then pushed by the protrusions 408 to above the discharge port 403. Because the iron is further from the strong magnet 409, it loses its attraction and is scraped by the soft scraper 407, falling into the discharge port 403. The concrete waste, now free of iron, continues to move with the conveyor device 6, and then the process is initiated. Motor 2 509 causes eccentric shaft 511 to start rotating. Eccentric shaft 511 drives movable plate 510 to rotate. Movable plate 510 drives connecting block 503 to rotate. Connecting block 503 drives device housing 3 501 to vibrate. Subsequently, the crushed concrete waste falls into device housing 3 501. Through the vibration of device housing 3 501, smaller concrete waste falls from filter screen plate 1 504 onto filter screen plate 2 505. Subsequently, even smaller concrete waste falls into the bottom surface of device housing 3 501. Due to the vibration of device housing 3 501, all concrete waste gradually moves towards the discharge port and is finally discharged from each discharge port.

[0023] Through the above steps, starting motor 2 509 causes eccentric shaft 511 to start rotating. Eccentric shaft 511 drives movable plate 510 to rotate, movable plate 510 drives connecting block 503 to rotate, and connecting block 503 drives device housing 3 501 to vibrate. Subsequently, the crushed concrete waste falls into device housing 3 501. Through the vibration of device housing 3 501, smaller pieces of concrete waste fall from filter screen plate 1 504 onto filter screen plate 2 505. Subsequently, even smaller pieces of concrete waste fall into the bottom surface of device housing 3 501. Due to the vibration of device housing 3 501, all concrete waste gradually moves towards the discharge port and is finally discharged from each discharge port. This solves the problem that the crushed concrete waste is of different sizes, which is inconvenient for subsequent processing and utilization, and has low practicality.

[0024] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
