[0022] See attached document Figs. 1-2As shown, the construction waste recycling device with dust removal function in this embodiment includes a shell 10, a primary crushing mechanism 20, a screen 30, a secondary crushing mechanism 40, a guide plate 50, and a spraying mechanism 60. The shell 10 has an inlet and an outlet. The screen 30 is disposed inside the shell 10. The primary crushing mechanism 20 is disposed below the inlet and above one end of the screen 30. The secondary crushing mechanism 40 is disposed below the other end of the screen 30. The guide plate 50 is disposed below the screen 30 and / or the secondary crushing mechanism 40. The guide plate 50 is used to guide the construction waste after screening and / or the construction waste after being crushed by the secondary crushing mechanism 40 to flow down to the outlet. The spraying mechanism 60 is installed on the shell 10 and has a nozzle for spraying into the shell 10.

[0023] This application utilizes a primary crushing mechanism 20 and a secondary crushing mechanism 40 to achieve secondary crushing of construction waste, ensuring that the particle size of the construction waste discharged from the outlet is appropriate. Simultaneously, the particle size of the construction waste decreases after crushing. Due to the secondary crushing mechanism 40 positioned between the screen 30 and the outlet, there is a significant distance difference between the screen 30 and the ground below the outlet, and the secondary crushing mechanism 40 also has a certain height difference from the ground. If the construction waste after screening or secondary crushing is directly discharged from the outlet, the crushed construction waste, under the impact of the ground and the action of flowing air, will... Dust will be generated. Therefore, in this embodiment, a guide plate 50 is provided below the screen 30 and / or the secondary crushing mechanism 40 so that the construction waste after screening or secondary crushing is guided by the guide plate 50 and discharged from the outlet and then conveyed out by the conveyor belt, thereby weakening the impact of the construction waste and reducing dust. On the other hand, the spraying mechanism 60 sprays into the outer shell 10 to increase the humidity inside the outer shell 10. After the spray comes into contact with the construction waste, the moisture content of the construction waste increases, which solves the problem of dust generated by the construction waste falling on the guide plate 50, thereby achieving dust removal in the device.

[0024] Specifically, the spraying mechanism 60 includes a first nozzle 61 mounted on the housing 10, the first nozzle 61 facing upwards from the guide plate 50.

[0025] The first nozzle 61 sprays water above the guide plate 50 so that the spray comes into contact with the sieved and secondary crushed construction waste and settles onto the guide plate 50.

[0026] In this embodiment, preferably, the spraying mechanism 60 further includes at least two second nozzles 62 mounted on the housing 10, the second nozzles 62 facing upwards of the primary crushing mechanism 20 and the secondary crushing mechanism 40, respectively.

[0027] Construction waste generates a large amount of dust during crushing. The dust escapes from the inlet and outlet of the device and pollutes the atmosphere. Therefore, by setting a second nozzle 62 to spray above the primary crushing mechanism 20 and the secondary crushing mechanism 40, the dust generated by the construction waste in the primary crushing mechanism 20 and the secondary crushing mechanism 40 is settled, thereby achieving dust removal of the device.

[0028] Based on the above, the recycling device also includes a slag cleaning mechanism 70, which is installed on the outer casing 10 and can reciprocate near the upper end of the guide plate 50 to clean the upper surface of the guide plate 50.

[0029] Since the mist sprayed by the spraying mechanism 60 settles on the guide plate 50 after contacting the construction waste, when the construction waste has a high moisture content, the construction waste is prone to caking and slag formation on the guide plate 50, which affects the effectiveness of the guide plate 50 in drawing out the construction waste. Therefore, the slag removal mechanism 70 moves back and forth near the upper end of the guide plate 50 to clean the upper surface of the guide plate 50, ensuring that the surface of the guide plate 50 is smooth and ensuring the normal operation of the device.

[0030] Specifically, the slag removal mechanism 70 includes a scraper 71 and a drive assembly 72. The scraper 71 is slidably mounted on the inner wall of the housing 10, and the drive assembly is connected to the inner wall of the housing 10 and to the scraper 71.

[0031] The drive assembly 72 drives the scraper 71 to move, preventing construction waste from affecting the normal operation of the drive assembly 72. The drive assembly 72 can be a telescopic rod, which drives the connector 72 and the scraper 71 to move along the surface of the guide plate 50 by extending and retracting.

[0032] Preferably, the screen 30 includes a plurality of screen plates connected end to end, and each screen plate can be rotated within the outer casing 10 to adjust its tilt angle with respect to the horizontal plane.

[0033] The screen 30 includes at least two screen plates connected end to end. When the crushed construction waste falls freely onto the feed end of the screen plate, local material accumulation occurs. By adjusting the rotation of the first screen plate to make its screen surface angle larger, the material accumulated on the screen 30 can fall quickly, preventing material accumulation at the feed end of the screen plate. After the construction waste flows down to the second screen plate, the tilt angle of the second screen plate is adjusted to be smaller than that of the first screen plate, reducing the downward flow velocity of the construction waste falling onto the second screen plate and prolonging the material residence time, thereby improving screening efficiency. Different compositions of construction waste have different angles of repose. In this application, the tilt angle of the screen surface of each screen plate is adjustable, allowing for adjustment of the tilt angle of the screen surface for different compositions of construction waste, thus adapting to the rapid screening of different types of construction waste.

[0034] Specifically, the screen 30 includes a first screen plate 31 and a second screen plate 32. One end of the first screen plate 31 and the second screen plate 32 are rotatably mounted on the outer casing 10 and close to each other. The other ends of the two screen plates are movably connected to the outer casing 10. The outer casing 10 is provided with two first driving members 80. The two first driving members 80 are used to drive the other ends of the first screen plate 31 and the second screen plate 32 to rotate around the rotatable connection point with the outer casing 10.

[0035] One end of the first screen plate 31 and the second screen plate 32 are brought close to each other, and the other ends of the first screen plate 31 and the second screen plate 32 are moved away from each other to adjust the tilt angle of the screen surface of the first screen plate 31 and the second screen. This allows the first screen plate 31 and the second screen plate 32 to be connected end to end while the tilt angle of the screen surface can be adjusted, thus preventing construction waste from flowing down from the gap between the first screen plate 31 and the second screen plate 32.

[0036] Based on the above, the first driving member 80 is a telescopic rod, and the outer shell 10 is provided with two arc-shaped grooves. The other ends of the first sieve plate 31 and the second sieve plate 32 are respectively installed in the arc-shaped grooves and can move in the arc-shaped grooves respectively. The first driving member 80 is rotatably installed on the outer shell 10, and the telescopic end of the first driving member 80 is rotatably connected to the first sieve plate 31 or the second sieve plate 32. The first sieve plate 31 and the second sieve plate 32 are rotated by the telescopic drive of the first driving member 80 to adjust their tilt angle with the horizontal plane respectively.

[0037] One end of the first screen plate 31 and the second screen plate 32 are respectively connected to the outer shell 10 through the first elastic element 120, and the other end of the two are respectively connected to the first driving element 80 through the second elastic element 130. Vibrators are respectively installed on the first screen plate 31 and the second screen plate 32. After the vibrator generates vibration, the first screen plate 31 and the second screen plate 32 vibrate relative to the outer shell 10 and the first driving element 80, thereby realizing the rapid screening of construction waste on the first screen plate 31 and the second screen plate 32.

[0038] Preferably, the screen 30 in this application further includes a third screen plate 33, which is mounted on the housing 10 and located on the side of the second screen plate 32 away from the first screen plate 31. One end of the third screen plate 33 is hinged to the second screen plate 32, and the other end of the third screen plate 33 is movably mounted on the housing 10. The second drive member 90 is connected to the other end of the third screen plate 33 through the connecting rod assembly 100.

[0039] The inclination angle of the horizontal plane of the third screen plate 33, i.e. the inclination angle of the screen surface, is smaller than that of the second screen surface. This prevents the bottom particles from not being screened through due to excessive flow rate, ensuring that the remaining material on the screen is fully screened, which is conducive to further improving the screening efficiency.

[0040] In order to ensure that the third screen plate 33 and the second screen plate 32 are connected end to end and to prevent construction waste from flowing down through the gap between the second screen plate 32 and the third screen plate 33, one end of the third screen plate 33 is hinged to the second screen plate 32. After the second screen plate 32 drives the third screen plate 33 to rotate synchronously, the second driving member 90 drives the third screen plate 33 to rotate to adjust the tilt angle of the screen surface of the third screen plate 33.

[0041] Specifically, the outer casing 10 is provided with a movable groove, the other end of the third sieve plate 33 is provided with a coupling, the coupling passes through the movable groove, and the connecting rod assembly 100 includes two connecting rods that are hinged to each other. One end of the connecting rod assembly 100 is connected to the coupling, and the other end is connected to the second driving member 90.

[0042] Referring to the accompanying drawings, when the second screen plate 32 rotates, it drives the third screen plate 33 to rotate synchronously. The third screen plate 33 rotates relative to the second driving member 90 via the connecting rod assembly 100, thus preventing the second driving member 90 from restricting the rotation of the third screen plate 33. After the second screen plate 32 has finished rotating, the second driving member 90 then drives the other end of the third screen plate 33 to rotate.

[0043] Preferably, the other end of the third screen plate 33 is connected to the connecting rod assembly 100 via a third elastic element 140. A vibrator is installed on the third screen plate 33. The second screen plate 32 and the third screen plate 33 are connected to each other, so that the construction waste on the third screen plate 33 can be vibrated and screened under the action of the vibrator (not shown in the figure). The vibrator is a prior art in this field. The installation position and working distance of the vibrator are not described in detail in this application.

[0044] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
