It involves feeding the construction waste into a crushing system for crushing, then using a screening system to separate particles of different sizes, and finally using a conveying system to transport the processed construction waste to a designated location for further processing, thereby achieving resource reuse.

[0003] Existing construction waste recycling devices require frequent cleaning and replacement of the screens. If the screens cannot be quickly disassembled, maintenance requires more time and effort, increasing the difficulty of maintenance. Therefore, a construction waste recycling device is proposed to improve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a construction waste recycling device. By pressing the pressing plate inward, the pressing plate drives the cylinder to move, which in turn drives the rod to move, causing the rod to drive the limiting post to move. Then, by rotating the pressing plate, the pressing plate drives the limiting post to engage with the limiting groove. Finally, by pulling the pressing plate outward, the pressing plate drives the limiting post to separate from the limiting groove, achieving a quick-release effect. This solves the problem that in existing construction waste recycling devices, the screen needs frequent cleaning and replacement. If the screen cannot be quickly released, maintenance requires more time and effort, increasing the difficulty of maintenance.

[0005] This utility model is achieved through the following technical solution:

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 This utility model provides a technical solution: a construction waste recycling device, wherein the box 1 has four first circular holes 101, four sliding grooves 102 and second circular holes 103, and the quick-release assembly 3 includes a cylinder 301 and a spring 304. Four cylinders 301 are provided. The cylinders 301 pass through the first circular holes 101 and cooperate with the sliding grooves 102. The rods 302 pass through the second circular holes 103 and cooperate with the limiting grooves 201. One end of the spring 304 is installed on the cylinder 301, and the other end of the spring 304 cooperates with the sliding grooves 102. The spring 304 is located outside the rods 302 and is used to reset the quick-release assembly 3.

[0024] When the screen frame 2 needs to be replaced, with a round rod 302 installed at one end of the cylinder 301 and a pressing plate 305 installed at the other end, press the pressing plate 305 inward to make the pressing plate 305 drive the round rod 302 to move. With a limit post 303 installed at the end of the round rod 302 away from the cylinder 301, and with the limit post 303 cooperating with the limit groove 201, the round rod 302 drives the limit post 303 to move. Then rotate the pressing plate 305 to make the pressing plate 305 drive the limit post 303 to rotate until the limit post 303 cooperates with the limit groove 201. Then pull the pressing plate 305 outward to make the pressing plate 305 drive the limit post 303 to separate from the limit groove 201. With four limit grooves 201 opened on the screen frame 2, the box 1 and the screen frame 2 are separated, achieving quick disassembly of the screen frame 2.

[0025] The crushing assembly 4 includes a feed hopper 401, on which two sets of circular grooves 402 are provided. Each set of circular grooves 402 has two parts. A first crushing roller 403 is rotatably fitted on one set of circular grooves 402, and a second crushing roller 404 is rotatably fitted on the other set of circular grooves 402.

[0026] When construction waste needs to be crushed, with the feed hopper 401 installed on the housing 1 and the feed hopper 401 having a bottom opening, the construction waste is poured into the feed hopper 401. With a motor connected to the other end of the first crushing roller 403, the motor is turned on by an external drive source, causing the motor's power output shaft to drive the first crushing roller 403 to rotate. A drive gear 405 is installed at one end of the first crushing roller 403, and a driven gear 406 is installed at the end of the second crushing roller 404 near the drive gear 405. With the drive gear 405 and the driven gear 406 meshing, the first crushing roller 403 drives the drive gear 405 to rotate. The drive gear 405 drives the driven gear 406 to rotate in the opposite direction, while simultaneously driving the second crushing roller 404 to rotate in the opposite direction. With the first crushing roller 403 and the second crushing roller 404 meshing, the construction waste is effectively crushed.

[0027] When it is necessary to vacuum the dust generated by the crushing components, the vacuuming component 5 includes a funnel-shaped suction port 501 located in the feed hopper 401. The funnel-shaped suction port 501 has a dust conveying pipe section that passes through the feed hopper 401 through a hole, allowing the funnel-shaped suction port 501 to absorb the dust in the feed hopper 401. A suction pipe 502 is installed on the funnel-shaped suction port 501, and a bag filter 503 is installed at the end of the suction pipe 502 away from the funnel-shaped suction port 501. The bag filter 503 is bolted to the feed hopper 401, allowing the dust to pass from the funnel-shaped suction port 501 through the suction pipe 502 and finally into the bag filter 503, achieving the effect of dust removal and avoiding the problem of dust and particulate matter generated during the crushing process affecting the health of the operators.

[0028] Two through holes 104 are provided on the housing 1. The two ends of the electromagnetic iron removal roller 6 are respectively rotatably engaged with the two through holes 104. The electromagnetic iron removal roller 6 is connected to an external power source. With a motor connected to the shaft of the electromagnetic iron removal roller 6, the motor is turned on by the external drive source, so that the power output shaft of the motor drives the electromagnetic iron removal roller 6 to rotate. With the electromagnetic iron removal roller 6 located directly below the feed hopper 401, the electromagnetic iron removal roller 6 can adsorb the steel bars and iron filings in the crushed construction waste. When a lot of iron filings are adsorbed on the electromagnetic iron removal roller 6, the power can be disconnected to make the electromagnetic iron removal roller 6 lose its magnetism, thus completing the recycling of iron filings and realizing the recycling of metal parts in construction waste.

[0029] The box 1 is equipped with a vibration motor 7, which causes the construction waste to jump and separate continuously on the screen frame 2 through vibration. Four support legs 8 are evenly distributed on the side wall of the box 1. The support legs 8 are used to support the entire device and ensure that the device can be placed stably on the ground.

[0030] The housing 1 is equipped with a first discharge port 9, which is located at the bottom of the screen frame 2. The first discharge port 9 is used to discharge smaller particles after crushing. The housing 1 is equipped with a second discharge port 10, which is located at the opening of the screen frame 2. The second discharge port 10 is used to discharge larger lumps.
