[0004] However, during the use of the device, waste building blocks of different sizes will affect the feeding of the first crushing roller and the second crushing roller, thereby affecting the crushing efficiency. Utility Model Content

[0005] In view of the above problems, the utility model provides an aerated concrete waste recycling system, which drives several groups of rotating roller assemblies to move through a rotating bracket. The rotating roller assemblies rotate to transport materials in the feeding area, so that the smaller the volume of the material, the higher the platform it stays on, and cooperates with corresponding crushing assemblies to crush the material, thereby solving the technical problem in the prior art that materials of different specifications are easily accumulated at the feed port, thereby affecting the crushing efficiency.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0032] Example:

[0033] like Figures 1 to 3As shown, an aerated concrete waste recycling system includes a frame 1, a silo assembly 2, a material-dispensing mechanism 3 and a crushing mechanism 4; the silo assembly 2 includes a silo body 21 installed on the frame 1 in a cylindrical shape and a plurality of platforms 22 arranged in a circumferential array and distributed in a stepped manner in the silo body 21; the material-dispensing mechanism 3 is rotatably installed above the silo body 21, and includes a rotating bracket 31, a plurality of rotating roller assemblies 32 arranged in a circumferential array and radially distributed on the rotating bracket 31, and a plurality of rotating roller assemblies 32 driven to rotate in parallel. The driving assembly a33 for stepping rotation and the driving assembly b34 for driving the rotating bracket 31 to rotate, a feeding area 30 corresponding to the platform 22 is formed between two adjacent groups of the rotating roller assemblies 32; the crushing mechanism 4 includes crushing roller assemblies 41 installed one by one under the platform 22 and a driving assembly c42 for driving the crushing roller assemblies 41 to rotate; several groups of the rotating roller assemblies 32 drive the material to move from the high platform 22 to the low platform 22, and the crushing roller assemblies 41 rotate to crush the material.

[0034] It should be noted that the areas of the two adjacent groups of rotating roller assemblies 32 are both feeding areas.

[0035] Further, such as Figure 1 As shown, the silo assembly 2 further includes a top cover 23 disposed above the silo body 21 and a feed barrel 24 disposed above the top cover 23 , and the feed barrel 24 is disposed corresponding to the uppermost platform 22 .

[0036] It should be noted that, when feeding, any one of the feeding areas 30 needs to move to between the feeding cylinder 24 and the uppermost platform 22 .

[0037] Further, such as Figure 3 and Figure 4 As shown, the rotating roller assembly 32 includes a roller body 321 radially arranged along the rotating bracket 31 and blades 322 spirally arranged on the roller body 321 .

[0038] Furthermore, the blades 322 on two adjacent groups of the roller bodies 321 are arranged to surround each other in opposite directions.

[0039] Furthermore, the driving component b34 includes a motor mounting frame 341 mounted on the frame 1, a motor b342 mounted on the motor mounting frame 341, a gear a343 arranged on the outside of the rotating bracket 31, and a gear b344 connected to the motor b342 and meshing with the gear a343.

[0040] It should be noted that, under the driving action of the motor b342, each time the gear b344 drives the gear a343 to rotate at a constant angle, that is, when the feed area 30 and the platform 22 are aligned, the motor b342 stops moving after the feed area 30 and the platform 22 are aligned.

[0041] It should be further explained that the motor b342 is a 1.1kw three-phase asynchronous motor equipped with a k67 reducer.

[0042] Further, such as Figure 4 As shown, the driving assembly a33 includes a bevel gear a331 coaxially arranged at the end of the roller body 321 and located in the rotating bracket 31, a bevel gear b332 coaxially arranged with the rotating bracket 31 and meshing with several groups of the bevel gears a331, and a motor a333 installed on the rotating bracket 31 and with a power shaft coaxially fixed with the bevel gear b332.

[0043] It should be noted that the motor b342 stops moving, the motor a333 drives the bevel gear b332 to rotate, the bevel gear b332 drives several groups of bevel gears a331 to rotate, and then drives the roller body 321 to rotate, and the blades 322 drive the material to move on the platform 22.

[0044] It should be further explained that the motor a342 is a 160 series reducer equipped with a 1.5KW servo motor.

[0045] Furthermore, the crushing roller assembly 41 includes a feed port 411 opened on the platform 22 , two groups of crushing rollers 412 arranged side by side below the feed port 411 and radially along the rotating bracket 31 , and a plurality of groups of crushing rods 413 distributed on the surface of the crushing rollers 412 .

[0046] It should be noted that the materials located on the platform 22 and around the feed port 411 will enter the feed port 411 when the blades 322 drive the larger materials to move, and then can be crushed by the crushing roller 412 .

[0047] Furthermore, the center distances of two groups of crushing rollers 412 in the plurality of groups of crushing roller assemblies 41 are uniformly set, the gap between the two groups of crushing rollers 412 increases as the height of the corresponding platform 22 decreases, and the length of the crushing rod 413 decreases as the height of the corresponding platform 22 decreases.

[0048] It should be noted that if Figure 6 and Figure 7As shown, along the rotation direction of the rotating bracket 31, the height of the platform 22 decreases step by step, the material staying on the upper level of the platform 22 is smaller in volume than the material staying on the platform 22, the gap of the crushing roller 412 matched therewith will increase accordingly, and the length of the crushing rod 413 will become shorter.

[0049] Further, such as Figure 5 As shown, the driving assembly c42 includes a gear c421 coaxially arranged with the crushing roller 412 and located outside the crushing roller 412, a gear d422 located between the two groups of gears c421 and meshing with the two groups of gears c421 at the same time, and a motor c423 connected to the gear d422.

[0050] It should be noted that the motor c423 drives the gear d422 to rotate, and the gear d422 drives the two groups of gears c421 to rotate, thereby driving the crushing roller 412 to rotate.

[0051] Working process:

[0052] like Figures 1 to 3 As shown, the material enters the feeding area 30 through the feeding barrel 24 and is located on the topmost platform 22. The motor b342 drives the bevel gear b332 to rotate, thereby driving several groups of bevel gears a331 to rotate, and then driving the roller body 321 to rotate. The blade 322 drives the material on the platform 22 to move. At the same time, the motor c423 drives the gear c421 to rotate through the gear d422, thereby driving the crushing roller 412 to rotate. The material with a suitable volume on the platform 22 will pass through the feeding port 411 and enter between the two groups of crushing rollers 412 for crushing. Then the motor b342 drives the gear b344 to rotate, thereby driving the gear c343 to rotate, and then driving the rotating bracket 31 to rotate. The roller body 321 brings the larger material that has not entered the feeding port 411 to the next platform 22, and then repeats the above process.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
