Technical Field
[0001] This utility model belongs to the technical field of concrete block production equipment, and in particular relates to a raw material crushing device for autoclaved aerated concrete blocks. Background Technology
[0002] With the booming development of the construction industry, autoclaved aerated concrete (AAC) blocks, as a new type of lightweight, high-strength, and thermally insulating building material, are in high demand. In the production process of AAC blocks, the raw material crushing device is a crucial link, and its crushing effect directly affects the key properties of the blocks, such as strength and density. Therefore, a high-efficiency AAC block raw material crushing device is needed to process the raw materials.
[0003] However, existing crushing devices are not convenient for vibrating and cleaning the filter screen during use. Raw materials accumulate and clog the surface of the filter cartridge, making it difficult for the crushed material to pass through the filter cartridge into the lower part of the crushing box. This not only reduces the screening efficiency after crushing but also interrupts the continuity of the crushing process. Utility Model Content

By setting up a vibration section, it solves the problem that existing crushing devices are not convenient to clean the filter screen by vibration during use, and the raw material will accumulate and block the surface of the filter cylinder. This makes it difficult for the crushed material to pass through the filter cylinder into the lower part of the crushing box, which not only reduces the screening efficiency after crushing, but also interrupts the continuity of the crushing process.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0006] This utility model relates to a raw material crushing device for autoclaved aerated concrete (AAC) blocks, comprising a support frame and a crushing box fixedly connected to the support frame, and further comprising: a crushing section disposed on the crushing box; an oscillating section mounted on the crushing box; a quantitative discharge section disposed at the bottom of the crushing box; the oscillating section comprising an oscillating assembly disposed above the support frame; and a power assembly mounted on the top of the crushing box; the oscillating assembly comprising a rectangular box disposed on the crushing box, an oscillating slider slidably connected to the inner wall of the rectangular box, a spring telescopic rod fixedly connected to the bottom inner wall of the rectangular box, the top of the spring telescopic rod fixedly connected to the oscillating slider, and an extrusion block fixedly connected to the right side of the oscillating slider, the right side of the extrusion block extending outside the rectangular box; wherein, the rectangular box only contacts the crushing box, and a groove for the extrusion block to slide is provided on the right side of the rectangular box; the oscillating assembly generates oscillation through the reciprocating motion and impact of the oscillating slider, assisting in the screening of materials on the filter cartridge and preventing clogging.
[0007] Furthermore, the pulverizing section includes a feed pipe connected to the left side of the pulverizing chamber, a motor is fixedly connected to the right side of the pulverizing chamber, the output shaft of the motor is fixedly connected to a rotating shaft via a coupling, a filter cartridge is fixedly connected to the inner wall of the pulverizing chamber, and a pulverizing component is provided on the rotating shaft; wherein, the right side of the feed pipe extends into the filter cartridge, the top of the filter cartridge is fixedly connected to a rectangular box, the quantitative discharge section includes a power component two, which is mounted on a support; and a discharge component, which is located at the bottom of the pulverizing chamber.
[0008] Furthermore, the power assembly includes two support blocks fixedly connected to the top of the crushing box. A motor is fixedly connected to the rear side of the support block located at the rear. The output shaft of the motor is fixedly connected to a rotating shaft via a coupling. An extrusion member is fixedly connected to the outer wall of the rotating shaft. The rotating shaft rotates through the two support blocks. The extrusion member is adapted to the extrusion block. The power assembly provides power to the oscillation assembly, enabling the oscillation slider to continuously impact the rectangular box, thereby causing the filter cartridge to oscillate.
[0009] Furthermore, the second power assembly includes a discharge pipe connected to the bottom of the crushing box, and a third motor is fixedly connected to the left side of the discharge pipe. The output shaft of the third motor is fixedly connected to a third rotating shaft via a coupling.

[0012] This utility model has the following beneficial effects:
[0013] 1. By setting up an oscillation section, the power component drives the oscillation component to operate. The periodic compression of the extrusion block by the protrusion and the rebound of the spring telescopic rod cause the oscillating slider to repeatedly hit the rectangular box, thereby causing the filter cartridge connected to the rectangular box to oscillate continuously. This prevents the raw material from accumulating and clogging on the surface of the filter cartridge, ensuring that the calibrated material can pass smoothly through the filter cartridge into the lower part of the crushing box, improving the screening efficiency of the raw material after crushing and ensuring the continuity of the crushing process.
[0014] 2. By setting up a quantitative discharge section, the discharge component is driven by the power component two. The hollow rod is driven by the motor to rotate, and the discharge trough on the hollow rod rotates with it. Each time, a discharge trough full of material is rotated to the bottom, and the material is discharged from the discharge pipe under the action of gravity. This realizes the quantitative output of the crushed material, avoids the situation of inconsistent output, facilitates the accurate control of raw material usage in subsequent production processes, and improves the stability of the autoclaved aerated concrete block production process.

A pressing block 214 is fixedly connected to the right side of the oscillation slider 212. The right side of the pressing block 214 extends outside the rectangular box 211.

The power assembly 22 includes... The system includes two support blocks 221 fixedly connected to the top of the crushing chamber 112.

[0028] A specific application of this embodiment is as follows: During use, after the raw material is placed into the feed pipe 113, motor 114 is turned on. Motor 114 drives the crushing frame 116 to rotate via shaft 115, thereby crushing the raw material falling into the filter cartridge 117. The crushed material that meets the standards will fall through the filter cartridge 117 into the lower half of the crushing box 112 for storage. Simultaneously with turning on motor 114, motor 222 on the rear support block 221 is also turned on. Motor 222 drives the protrusion 224 to rotate via shaft 223. During rotation, the protrusion 224 will squeeze the pressing block 214, causing it to move downwards. The pressing block 214 drives the oscillating slider 212 inside the rectangular box 211 to slide down, compressing the spring telescopic rod 213 until the protrusion 224 separates from the pressing block 214. The spring telescopic rod 213 rebounds, causing the oscillating slider 212 to collide with the rectangular box 211. Subsequently, the oscillating slider 212 will slide down again due to the impact force, repeating the above process until the kinetic energy is exhausted. The rotating shaft 223 continues to rotate, causing the oscillating slider 212 to continuously collide with the rectangular box 211. The rectangular box 211 generates oscillation on the filter cartridge 117. When discharging, the motor 312 is turned on. The motor 312 drives the hollow rod 321 to rotate through the rotating shaft 313. The discharge trough 322 on the hollow rod 321 rotates accordingly. The discharge trough 322 filled with material at the top will move to the bottom as it rotates. The material falls with gravity and is discharged from the discharge pipe 311. This process is repeated, discharging material from one discharge trough 322 each time, achieving the purpose of quantitative discharge.
