[0022] Please refer to Figures 1-5 , the present utility model provides a waste crushing device for aerated concrete slabs, which is characterized in that: it includes a box body assembly 1, two sets of crushing components 2 are installed inside the box body assembly 1, a screening component 3 is installed on the top of the box body assembly 1, the box body assembly 1 includes a first crushing box 11 and a second crushing box 12, a filter plate 13 is fixedly installed inside the second crushing box 12, one end of the filter plate 13 penetrates to the outside of the first crushing box 11, and the discharge end of the filter plate 13 is located above the second crushing box 12. The screening component 3 includes a support plate 31 installed on the top of the second crushing box 12, two sets of fixed frames 32 are installed on the top of the support plate 31, sliding grooves 33 are opened on the opposite sides of the two sets of fixed frames 32, a T-shaped frame 36 is slidably installed inside the sliding grooves 33, an electromagnetic plate 37 is fixedly installed at the bottom of the T-shaped frame 36, and the electromagnetic plate 37 is located above the second crushing box 12.

[0023] During use, through the setting of the crushing component 2, the servo motor 22 is started to drive the rotation of the first crushing roller 27 and the second crushing roller 28, achieving the effect of crushing the waste of aerated concrete slabs. Utilizing the different strengths of steel bars and concrete, the particle sizes after crushing are different. After being filtered by the filter plate 13 below, the small particle debris falls through the filter holes 14 onto the discharge plate 15 and is discharged. The steel bar debris and the large particle concrete debris enter the second crushing box 12. Through the screening component 3 placed on the top of the second crushing box 12, the electromagnetic plate 37 in the screening component 3 is used to adsorb the steel bars in the debris, thereby achieving the effect of separating the steel bar waste from the aerated concrete slabs.

[0024] The crushing component 2 includes an L-shaped bracket 21. A servo motor 22 is bolted to the top of the L-shaped bracket 21. The output shaft of the servo motor 22 is key-connected with a driving wheel 23. The driving wheel 23 is meshed and connected with a driven wheel 24. By using the connection relationship among the servo motor 22, the driving wheel 23, and the driven wheel 24, the servo motor 22 is started to drive the driving wheel 23 and the driven wheel 24 to rotate simultaneously, and the rotation directions of the driving wheel 23 and the driven wheel 24 are different.

[0025] One end of the driving wheel 23 is fixedly installed with a first rotating rod 25. One end of the driven wheel 24 is fixedly installed with a second rotating rod 26. The first crushing roller 27 is fixedly installed on the outer side of the first rotating rod 25. The second crushing roller 28 is installed on the outer side of the second rotating rod 26, achieving the effect that the driving wheel 23 and the driven wheel 24 respectively drive the first crushing roller 27 and the second crushing roller 28 to rotate simultaneously.

[0026] A set of crushing components 2 are installed inside both the first crushing box 11 and the second crushing box 12. The two groups of L-shaped brackets 21 are respectively installed on the front faces of the first crushing box 11 and the second crushing box 12. The outer arc surfaces of one group of the first rotating rod 25 and the second rotating rod 26 are rotationally connected to the first crushing box 11 in a penetrating manner. The outer arc surfaces of the other group of the first rotating rod 25 and the second rotating rod 26 are rotationally connected to the second crushing box 12 in a penetrating manner, improving the stability of the fixed rotation of the first rotating rod 25 and the second rotating rod 26.

[0027] An outlet plate 15 is installed inside the second crushing box 12. One end of the outlet plate 15 penetrates to the outside of the first crushing box 11, ensuring that the debris in the first crushing box 11 and the second crushing box 12 is discharged to the same position.

[0028] Filter holes 14 are opened at the top of the filter plate 13. The filter holes 14 are located below one group of the first crushing roller 27 and the second crushing roller 28. The waste of the aerated concrete slabs falls onto the filter plate 13 after being preliminarily crushed in the first crushing box 11, facilitating the filtering of the debris by the filter plate 13.

[0029] One end of the fixing frame 32 is provided with a support frame 34. The top of the support frame 34 is bolted with an electric push rod 35. One end of the electric push rod 35 is fixedly connected to the middle of the T-shaped frame 36. Starting the electric push rod 35 can drive the T-shaped frame 36 to move.

[0030] During specific use: Put the waste of aerated concrete plates into the upper opening of the first crushing box 11. Start the servo motor 22 to rotate counterclockwise, driving the driving wheel 23 to rotate counterclockwise. The counterclockwise rotation of the driving wheel 23 drives the driven wheel 24 to rotate clockwise. The rotation of the driving wheel 23 and the driven wheel 24 drives the rotation of the first rotating rod 25 and the second rotating rod 26. The rotation of the first rotating rod 25 and the second rotating rod 26 drives the rotation of the first crushing roller 27 and the second crushing roller 28, thus achieving the effect of crushing the waste of aerated concrete plates.

[0031] The crushed materials after crushing fall onto the lower filter plate 13. Through the filter holes 14 on the filter plate 13, part of the small-particle crushed materials are filtered to the lower discharge plate 15 and directly discharged. The steel bar fragments and large-particle concrete fragments fall into the feed port of the second crushing box 12 along the inclined direction of the filter plate 13. At the same time, through the screening assembly 3, start the electromagnetic plate 37 above the second crushing box 12. Using the suction force of the electromagnetic plate 37 on iron products, the steel bar fragments are screened out from the crushed materials. After the screening is completed, start the electric push rod 35 to contract to move the electromagnetic plate 37 to the left side of the second crushing box 12, and turn off the electromagnetic plate 37. The steel bar fragments fall to the designated location, achieving the effect of separately recycling the steel bars.

[0032] The crushed materials after screening enter the second crushing box 12. Through the re-crushing of the crushing assembly 2, the crushed materials fall onto the lower discharge plate 15 and are discharged to the designated location by using the inclination of the discharge plate 15. Through the setting of the above device, the effect of crushing the waste of concrete plates is achieved, and at the same time, the waste steel bars are screened out from the crushed materials, improving the efficiency of resource recycling and classification.
