[0002] With the development of society and the continuous improvement of urbanization rate, a large amount of construction waste will inevitably be generated in the process of urbanization. A large part of these construction wastes is concrete. Due to its large volume, it is difficult for workers to clean it up. The common method is to crush it. However, due to the unreasonable structural design of the existing crushing device, it is easy to have incomplete crushing during the concrete crushing process, resulting in the need for secondary crushing. In addition, scrap metal is usually mixed in the concrete, which has a certain recycling value. If the crushed construction waste is directly processed, it will cause a waste of resources. Therefore, a crushing device for recycling construction waste is proposed. Utility Model Content

[0022] The embodiments of the present application solve the problems in the prior art by providing a crushing device for recycling construction waste.

[0023] The technical solution in the embodiment of the present application is to solve the above problems, and the overall idea is as follows:

[0024] The specific structure of this embodiment is as follows: Figure 1-3 As shown, a crushing device for recycling construction waste includes: a device body 1, a support leg 2 is arranged at the bottom of the device body 1, a hopper 3 is arranged on one side of the top of the device body 1, and a crushing and recycling mechanism 4 is arranged inside the device body 1.

[0025] In some examples, a support leg 2 is fixedly installed at the bottom of the device body 1, a hopper 3 is fixedly installed on one side of the top of the device body 1, and the crushing recovery mechanism 4 includes a crushing groove 401, a separation chamber 402, a crushing roller 403, a first motor 404, a connecting rod 405, a guide plate 406, a water tank 407, a water pipe 408, a nozzle 409, a connecting plate 410, a discharge groove 411, a magnetic plate 412, a rubber pad 413, a second motor 414, a vibration plate 415 and a discharge port 416. A crushing groove 401 and a separation chamber 402 are opened inside the device body 1, and the crushing groove 401 and the separation chamber 402 are connected to each other, and the crushing groove 401 is in the shape of a volute, the crushing roller 403 is located on one side of the crushing groove 401, and the first motor 404 is fixedly installed on the surface of the device body 1. A connecting rod 405 is fixedly installed at one end of the hopper 3, and one end of the connecting rod 405 extends into the crushing groove 401 and is fixedly connected to the crushing roller 403. A guide plate 406 is fixedly installed on one side of the top of the inner wall of the separation chamber 402, and the guide plate 406 is inclined. The cement blocks enter between the crushing roller 403 and the crushing groove 401 through the hopper 3, and the crushing roller 403 is driven to rotate by the cooperation of the first motor 404 and the connecting rod 405 to squeeze and crush the cement blocks. Since the crushing groove 401 is in the shape of a volute, the smaller cement blocks after being squeezed will further enter the separation chamber 402 along the inner wall of one side of the crushing groove 401, while the larger cement blocks will stay between the crushing roller 403 and the crushing groove 401 and be continuously crushed. The size of the cement blocks passing through is limited by the crushing roller 403 and the crushing groove 401, thereby improving the crushing effect.

[0026] In some examples, the water tank 407 is fixedly installed on one side of the device body 1, and a water pipe 408 is fixedly installed on the bottom of the water tank 407. One end of the water pipe 408 extends to one side of the guide plate 406 and is fixedly installed with a nozzle 409. The water flow sprayed by the nozzle 409 can further wet the crushed cement blocks and reduce the generation of smoke and dust.

[0027] In some examples, the connecting plate 410 is rotatably connected to one side of the inner wall of the separation chamber 402, and the connecting plate 410 is inclined, the discharge slot 411 is opened on the surface of the connecting plate 410, a magnetic plate 412 is fixedly installed at one end of the connecting plate 410, and a rubber pad 413 is glued to the bottom of one end of the magnetic plate 412. The second motor 414 is fixedly installed on the other side of the inner wall of the separation chamber 402, and a vibration plate 415 is fixedly installed at one end of the second motor 414, and one end of the vibration plate 415 is in contact with the rubber pad 413. The vibration plate 415 is pentagonal and the end is round. The discharge port 416 is opened on one side of the bottom of the inner wall of the separation chamber 402 and is located directly below the discharge chute 411. The crushed cement blocks further fall onto the surface of the magnetic plate 412, and the metal therein is adsorbed and separated by the magnetic plate 412. The vibration plate 415 is driven to rotate by the second motor 414 so that the vibration plate 415 continuously strikes the rubber pad 413 at the bottom of the magnetic plate 412, causing the magnetic plate 412 to vibrate continuously, and the cement blocks on its surface will further move to the surface of the connecting plate 410 and fall from the discharge chute 411 and then be discharged from the discharge port 416.

[0028] In a specific application scenario, cement blocks are fed into the hopper 3 so that they enter between the crushing roller 403 and the crushing trough 401, and the crushing roller 403 is driven to rotate by the cooperation of the first motor 404 and the connecting rod 405 to squeeze and crush the cement blocks. After being squeezed, the smaller cement blocks will further fall along the inner wall of one side of the crushing trough 401 to the guide plate 406, and further fall to the surface of the magnetic plate 412. While falling, water is sprayed out through the nozzle 409 to further wet the crushed cement blocks to reduce the generation of smoke and dust. After falling on the surface of the magnetic plate 412, the metal therein is adsorbed and separated by the magnetism of the magnetic plate 412, and the vibration plate 415 is driven to rotate by the second motor 414 so that the vibration plate 415 continuously hits the rubber pad 413 at the bottom of the magnetic plate 412, causing the magnetic plate 412 to vibrate continuously, and the cement blocks on its surface will further move to the surface of the connecting plate 410 and fall from the discharge trough 411 and further be discharged from the discharge port 416.

[0029] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
