[0028] like Figures 1 to 8 As shown, the present invention provides a graded crushing and mixing device for autoclaved aerated concrete blocks, comprising a fixed shell 1 and a crushing unit 11. A feed port 2 is fixedly installed on the top of the fixed shell 1, a drive motor 3 is fixedly installed on one side of the fixed shell 1, a driving gear 7 is fixedly installed on the output end of the drive motor 3, one side of the driving gear 7 is meshedly connected with a driven gear 8, the lower end of the driving gear 7 is meshedly connected with a movable component 5, a connecting pipe 10 is fixedly installed on the lower end of the fixed shell 1, a fixed support plate 9 is fixedly installed on the upper end of the inner cavity of the fixed shell 1, a vibration component 4 is fixedly installed on the upper end of the inner cavity of the fixed shell 1, and an extrusion component 6 is fixedly installed on the lower end of the inner cavity of the fixed shell 1.

[0029] The above scheme is adopted: through the cooperation of the vibration component 4 and the extrusion component 6, the drive motor 3 is started, and the drive motor 3 drives the driving gear 7, the driven gear 8 and the crushing unit 11 to rotate. The driving gear 7 and the driven gear 8 drive the two groups of crushing units 11 to rotate, and the autoclaved aerated concrete raw materials are crushed for the first time. The finer autoclaved aerated concrete raw materials pass through the slots on the surface of the fixed support plate 9 and fall from between the fixing part 403 and the connecting part 404, thereby enlarging the hole between the spring telescopic rod 402 and the fixing part 403, and then causing the autoclaved aerated concrete raw materials with larger particles to fall from between the spring telescopic rod 402 and the fixing part 403 to between the fixed shell 1 and the movable plate 602, so that the extrusion component 6 performs a secondary crushing on the autoclaved aerated concrete raw materials.

[0030] like Figure 2 、 Figure 3 As shown, the movable component 5 includes a connecting gear 501, a connecting shaft 502 located in the inner cavity of the fixed shell 1 is fixedly installed in the middle of the connecting gear 501, and a second fixed block 503 is fixedly installed in the middle of the connecting shaft 502. The vibration component 4 includes a fixed plate 401, a spring telescopic rod 402 and a second rectangular telescopic rod 408 are fixedly installed on the top of the fixed plate 401, a fixing member 403 is fixedly installed on one side of the fixed plate 401, and the inner cavity of the fixing member 403 is movably connected to a connecting member 404, a connecting plate 405 is fixedly installed on the side of the connecting member 404 away from the fixing member 403, a first rectangular telescopic rod 407 is fixedly installed on the side of the connecting plate 405 away from the connecting member 404, a rectangular plate 406 is fixedly installed on the side of the first rectangular telescopic rod 407 away from the connecting plate 405, a first fixed block 410 is fixedly installed on the bottom of the rectangular plate 406, and an arc spring 409 is fixedly installed on the top of the connecting member 404.

[0031] The above solution is adopted: through the cooperation of the connecting gear 501 and the connecting shaft 502, the driving gear 7 drives the connecting gear 501, the connecting gear 501 drives the connecting shaft 502 and the second fixed block 503 to rotate, the second fixed block 503 resists the first fixed block 410, so that the vibration component 4 moves upward, the connecting shaft 502 drives the two sets of moving plates 602 to move, so that the moving plate 602 pushes the connecting plate 405 and the first rectangular telescopic rod 407 to move, and through the cooperation of the fixed plate 401 and the spring telescopic rod 402, the second fixed block 5 03 conflicts with the first fixed block 410, the vibration assembly 4 moves upward. When the second fixed block 503 does not conflict with the first fixed block 410, the spring telescopic rod 402 drives the vibration assembly 4 to reset, preventing the autoclaved aerated concrete raw materials from being stuck between the fixing member 403 and the connecting member 404. When the two sets of mounting plates 601 move toward each other, they push the two sets of connecting plates 405 and the first rectangular telescopic rod 407 to move, so that the maximum diameter value between the fixing member 403 and the connecting member 404 is the same as the maximum diameter value of the slot hole on the surface of the fixed support plate 9.

[0032] like Figure 6 and Figure 7 As shown, the extrusion assembly 6 includes a mounting plate 601 and a movable part 607. A bellows 605 and a movable plate 602 are fixedly installed on the top of the mounting plate 601. A fixed cylinder 603 is fixedly installed on one side of the movable plate 602. The inner cavity of the fixed cylinder 603 is movably connected with a sleeve 604. A connecting column 609 is fixedly installed on the bottom of the sleeve 604. The inner cavity of the fixed cylinder 603 is movably connected with a movable column 610. A fixed tube 606 is installed on the top of the bellows 605. A pushing block 608 is fixedly installed on the side of the movable plate 602 close to the fixed cylinder 603.

[0033] The above solution is adopted: through the cooperation of the mounting plate 601 and the movable plate 602, when the two sets of mounting plates 601 move away from each other, the movable plate 602 drives the fixed cylinder 603, the sleeve 604 and the fixed tube 606 to move, and the movable plate 602 squeezes the bellows 605, so that the gas in the bellows 605 is discharged from the fixed tube 606, thereby causing the sleeve 604, the connecting column 609 and the movable column 610 to move, and the autoclaved aerated concrete raw material is crushed. When the sleeve 604 collides with the fixed shell 1, the sleeve 604, the connecting column 609 and the movable column 610 move into the inner cavity of the fixed cylinder 603, so that the autoclaved aerated concrete raw material is crushed again. At the same time, the pushing block 608 collides with the triangular block, causing the movable member 607 to move upward, thereby opening the groove between the fixed shell 1 and the connecting tube 10, so that the autoclaved aerated concrete raw material that has been crushed for the second time flows out of the connecting tube 10, and then proceeds to the next step of stirring and mixing.

[0034] like Figure 3 、 Figure 4 As shown, the connecting column 609 is fixedly connected to the movable column 610, the fixed tube 606 is fixedly connected to the movable plate 602, both ends of the connecting shaft 502 are provided with threads, and the thread directions are opposite, the bottom of the second fixed block 503 is an arc surface, the top of the fixed support plate 9 is provided with a slot, and the connecting tube 10 is arc-shaped.

[0035] The above solution is adopted: by cooperating with the connecting column 609 and the movable column 610, the connecting column 609 is fixedly connected to the movable column 610, so that the movable column 610 rotates when it moves in the limit groove of the inner cavity of the sleeve 604, and then the autoclaved aerated concrete raw materials that do not meet the crushing requirements and fall from between the fixed cylinder 603 and the sleeve 604 are crushed again, and the fixed tube 606 is fixedly connected to the movable plate 602, so that the movable plate 602 drives the fixed tube 606 to move and squeeze the corrugated tube 605 more stably. Through the design of the connecting shaft 502 and the second fixed block 503, the two ends of the connecting shaft 502 are provided with threads in opposite directions, so that when the connecting shaft 502 rotates, it drives the two groups The movable plates 602 move toward or away from each other, so that the extrusion assembly 6 performs secondary crushing on the autoclaved aerated concrete raw material. The bottom of the second fixed block 503 is an arc surface, which makes it easier to interfere with the first fixed block 410, causing the vibration assembly 4 to vibrate, thereby preventing the autoclaved aerated concrete raw material from being stuck between the fixing member 403 and the connecting member 404. Through the design of the fixed support plate 9 and the connecting pipe 10, a slot is provided on the top of the fixed support plate 9, so that the autoclaved aerated concrete raw material falls from the slot. The connecting pipe 10 is arc-shaped, so that the autoclaved aerated concrete raw material after the secondary crushing can be better slid from the connecting pipe 10 into the mixing chamber for further mixing.

[0036] like Figure 7 and Figure 8 As shown, the maximum diameter of the fixing member 403 and the connecting member 404 is the same as the maximum diameter of the slot, the bottom of the first fixing block 410 is an arc surface, a triangular block is provided on the side of the mounting plate 601 close to the movable plate 602, the top of the pushing block 608 is an inclined surface, a hole is provided on the side of the bellows 605 close to the movable member 607, a crushing knife is provided on the top of the sleeve 604, and an "L"-shaped slide groove is provided in the inner cavity of the fixed cylinder 603.

[0037] The above solution is adopted: through the design of the fixing member 403 and the connecting member 404, the maximum diameter value of the fixing member 403 and the connecting member 404 is the same as the maximum diameter value of the slot hole, so that when the slot hole between the fixing member 403 and the connecting member 404 reaches the maximum value, the larger autoclaved aerated concrete raw material falls from between the fixing member 403 and the connecting member 404, thereby allowing the extrusion component 6 to perform secondary crushing of the autoclaved aerated concrete raw material. The design of the arc surface at the bottom of the first fixing block 410 makes it easier for the second fixing block 503 to conflict with the first fixing block 410, causing the vibration component 4 to vibrate, thereby avoiding the autoclaved aerated concrete raw material from being stuck between the fixing member 403 and the connecting member 404. Through the design of the mounting plate 601 and the pushing block 608, the top of the triangular block and the pushing block 608 are inclined, so that when the movable plate 602 drives the fixing cylinder 603, the sleeve 604 and the pushing block 608 to move, the sleeve 604 and the fixing The shell 1 is in conflict, and the pushing block 608 is in conflict with the triangular block at this time, so that the pushing block 608 will conflict with the moving part 607 upward, causing the moving part 607 to move upward, thereby allowing the secondary crushed autoclaved aerated concrete raw materials to enter the mixing force from the connecting pipe 10, and then the autoclaved aerated concrete raw materials are stirred and mixed. Through the cooperation of the moving part 607 and the opening of the hole in the bellows 605, when the moving plate 602 squeezes the bellows 605 to the maximum, the moving part 607 moves upward, causing the gas in the bellows 605 to be discharged from the hole. The design of the crushing guide at the top of the sleeve 604 drives the crushing knife to rotate when the sleeve 604 rotates, thereby performing secondary crushing of the autoclaved aerated concrete raw materials. The design of the "L"-shaped slide groove enables the fixed cylinder 603 to rotate the "L"-shaped slide groove when moving, so that the crushing of the autoclaved aerated concrete raw materials meets the requirements of graded crushing for autoclaved aerated concrete blocks.

[0038] The working principle and use process of the present invention:

[0039] When in use, the driving motor 3 is started, and the autoclaved aerated concrete raw material is added from the feed port 2. The driving motor 3 drives the driving gear 7, the driven gear 8 and the crushing unit 11 to rotate. The driving gear 7 and the driven gear 8 drive the two groups of crushing units 11 to rotate, thereby performing the first crushing of the autoclaved aerated concrete raw material. The finer autoclaved aerated concrete raw material passes through the slots on the surface of the fixed support plate 9 and falls between the fixing member 403 and the connecting member 404. The driving gear 7 drives the movable component 5 to rotate. When rotating clockwise, the connecting gear 501 drives the connecting shaft 502 and the second fixed block 503 to rotate, so that the second fixed block 503 conflicts with the first fixed block 410, causing The first fixed block 410 drives the vibration assembly 4 to move upward, thereby causing the vibration assembly 4 to vibrate. When there is no interference, the spring telescopic rod 402 drives the vibration assembly 4 to reset, so that the second fixed block 503 can better interfere with the first fixed block 410 next time. The connecting shaft 502 drives the two sets of mounting plates 601 to move toward each other, so that the mounting plates 601 push the connecting plates 405, causing the first rectangular telescopic rod 407 to contract in the direction close to the rectangular plate 406, thereby enlarging the hole between the spring telescopic rod 402 and the fixing member 403, thereby causing larger particles of autoclaved aerated concrete raw materials to fall from between the spring telescopic rod 402 and the fixing member 403.

[0040] When rotating counterclockwise, the two sets of mounting plates 601 move in opposite directions, and the movable plate 602 drives the fixed cylinder 603, the sleeve 604 and the fixed pipe 606 to move closer to the connecting pipe 10. The movable plate 602 squeezes the bellows 605, so that the gas in the bellows 605 is discharged from the fixed pipe 606, and the connecting column 609 and the movable column 610 move along the "L" groove, thereby causing the sleeve 604 to rotate, thereby crushing the autoclaved aerated concrete raw materials. When the sleeve 604 conflicts with the fixed shell 1, the sleeve 604, the connecting column 609 and the movable column 610 are pressed against each other. The connecting column 609 and the movable column 610 move into the inner cavity of the fixed cylinder 603, thereby crushing the autoclaved aerated concrete raw material again. At the same time, the pushing block 608 abuts against the triangular block, causing the movable member 607 to move upward, thereby opening the groove between the fixed shell 1 and the connecting pipe 10, so that the autoclaved aerated concrete raw material that has been crushed for the second time flows out of the connecting pipe 10, and then proceeds to the next step of stirring and mixing, thereby achieving the effect of crushing the autoclaved aerated concrete raw material multiple times, thereby improving the quality of the steam-pressurized concrete blocks.
