Description

Technical Field

[0001] The utility model relates to the technical field of building material equipment, in particular to a crushing device with uniform proportioning for autoclaved aerated concrete slabs. Background Art

[0002] Autoclaved aerated concrete blocks are a new type of building material with light weight, porous structure, good heat insulation and fire resistance, and can be nailed, sawed, planed, and have a certain seismic resistance. It is an excellent new building material. Autoclaved aerated concrete blocks are produced through processes such as grinding, batching, mixing, casting, gas generation, static stopping, cutting, and autoclave curing. Construction waste sand powder and tailings sand generally belong to construction waste, but after being crushed, they can be used in the production of autoclaved aerated concrete blocks, which not only reduces the cost of waste treatment but also protects the environment.

[0003] Chinese Patent (authorization announcement number: CN 214765723 U, authorization announcement date: November 19, 2021) proposed a crushing device for waste autoclaved aerated concrete blocks. In this patent, by setting a servo motor, when the staff uses the device to crush concrete blocks, the staff only needs to start the servo motor through the control switch. With the cooperation of the first gear and the second gear, the first rotating shaft and the second rotating shaft can drive the crushing rollers to rotate simultaneously, thus achieving the effect of crushing concrete blocks.

[0004] The above patent outputs materials through a spiral blade after crushing by the crushing rollers. However, there are often materials that are not completely crushed during the crushing by the crushing rollers. The above patent is inconvenient to return the incompletely crushed materials for re-crushing, which affects the crushing quality of the patent. To facilitate reintroducing the incompletely crushed materials into the device for re-crushing and ensure the uniform proportioning of the subsequent autoclaved aerated concrete slab materials, we propose a crushing device with uniform proportioning for autoclaved aerated concrete slabs.

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to Figures 1-6 , the present utility model provides a technical solution: a crushing device for uniform mixing ratio of autoclaved aerated concrete slabs, including a housing 1. Support plates 7 are fixedly connected to the front and rear sides on the left and right sides of the housing 1. A screening component is installed between the four groups of support plates 7. A crushing component is installed inside the housing 1. A return component for unqualified materials is installed at the rear of the housing 1.

[0030] During use, the material is crushed by the crushing component and then enters the material screening component. The material screening component screens the crushed material. The qualified crushed material will be directly discharged, and the unqualified crushed material will enter the unqualified material return component. The unqualified material return component will re-inject the incompletely crushed material into the housing 1, and the crushing component will crush it again, thereby improving the crushing quality and facilitating the subsequent material ratio of autoclaved aerated concrete slabs.

[0031] The crushing component includes crushing rollers 2 on the front and back sides. A rotating rod 17 is fixedly sleeved on the crushing roller 2. The left end of the rotating rod 17 is rotatably connected to the inner wall of the housing 1. The right end face of the housing 1 is fixedly connected with a first dust-proof housing 3. The right end of the rotating rod 17 rotatably extends into the interior of the first dust-proof housing 3. A transmission gear 16 is fixedly sleeved on the outer surface of the rotating rod 17.

The output end of the driving motor 4 is fixedly connected to the end of one of the rotating rods 17.

[0032] When using the crushing component, the driving motor 4 works. The driving motor 4 will drive one of the rotating rods 17 to rotate. Since the two transmission gears 16 are meshed with each other, the two crushing rollers 2 will rotate in opposite directions, and the material will pass through the gap between the two crushing rollers 2, thereby realizing the crushing of the material.

[0033] The material screening component includes a material screening frame 10. Sliding grooves 21 are formed on the front and back sides of the material screening frame 10.

The qualified crushed materials will pass through the screening plate 8 and enter the discharge housing 9, and finally be discharged through the discharge port 28. The unqualified crushed materials will enter the subsequent unqualified material return component for material return. When the driving motor 4 works, since the two groups of transmission gears 16 are meshed with each other, the connecting rod 18 will be driven to rotate. When the connecting rod 18 rotates, it will drive the transmission rod 19 to rotate. When the transmission rod 19 rotates, it will drive the transmission disc 5 to rotate. When the transmission disc 5 rotates and cooperates with the transmission strip plate 6, the screening frame 10 will move left and right reciprocally, thereby improving the screening effect of the screening frame 10.

[0035] The unqualified material return component includes a return cylinder 15. The return cylinder 15 is fixedly assembled at the rear side of the housing 1. A return rod 27 is rotatably installed inside the return cylinder 15. A spiral return blade 12 is installed on the return rod 27. A return box 22 is installed on the left side of the return cylinder 15. A receiving shell 11 is installed on the left side of the housing 1. A return pipe 14 is fixedly communicated above the return cylinder 15.

[0036] The unqualified crushed materials will fall into the receiving shell 11, and then fall into the return box 22 under the action of their own gravity, and then enter the return cylinder 15. Finally, they will fall back into the housing 1 through the return pipe 14 under the lifting action of the spiral return blade 12, realizing the return of unqualified crushed materials.

[0037] The top end of the return rod 27 is fixedly connected with a driven belt pulley. The left side of the housing 1 is fixedly connected with a second dust-proof shell 25. The left end of the rear side rotating rod 17 rotates out of the left side of the housing 1, and the left end of the rear side rotating rod 17 is fixedly connected with a first transmission bevel gear. A rotating vertical rod 29 is rotatably installed inside the second dust-proof shell 25. Two ends of the rotating vertical rod 29 are respectively fixedly connected with a second transmission bevel gear and a third transmission bevel gear. The third transmission bevel gear is meshed with the first transmission bevel gear. A rotating vertical rod 26 rotatably penetrates through the upper end surface of the second dust-proof shell 25. The bottom end of the rotating vertical rod 26 is fixedly connected with a fourth transmission bevel gear. The fourth transmission bevel gear is meshed with the second transmission bevel gear. The top end of the rotating vertical rod 26 is fixedly connected with a driving belt pulley. A transmission belt 13 is tensioned and sleeved between the driving belt pulley and the driven belt pulley.

[0038] When the driving motor 4 works, it will drive the rotating vertical rod 29 to rotate. When the rotating vertical rod 29 rotates, it will drive the rotating vertical rod 26 to rotate. When the rotating vertical rod 26 rotates, it will drive the return rod 27 to rotate. Therefore, when the driving motor 4 drives the crushing roller 2 to crush, it will also drive the spiral return blade 12 to rotate, avoiding the need to install multiple driving devices and reducing the equipment cost.

[0039] The material receiving shell 11 is rotatably installed on the support plate 7 at the left rear through a rotating shaft. The left end of the front rotating rod 17 rotatably extends outside the shell 1, and a cam 24 is fixedly connected to the left end of the front rotating rod 17. A steel wire rope 23 is rotatably installed between the cam 24 and the material receiving shell 11.

[0040] When the rotating rod 17 rotates, it will drive the cam 24 to rotate. When the cam 24 rotates, it will pull the material receiving shell 11 to rotate up and down reciprocally through the steel wire rope 23, thereby assisting the material on the material receiving shell 11 to enter the return material box 22.

[0041] A number of heat dissipation fins are installed on the outer surface of the drive motor 4, which is more convenient for the drive motor 4 to dissipate heat and improves the service life of the drive motor 4.

[0042] The bottom of the support plate 7 is fixedly installed with a shock-absorbing rubber plate to improve the shock absorption of the equipment.

[0043] The lower surface of the material receiving shell 11 is an arc plate structure, and the height of the arc plate gradually decreases from front to back, which is convenient for the material on the material receiving shell 11 to be discharged.

[0044] The cross-sections of the sliding groove 21 and the sliding block 20 are both in a 'T'-shaped structure.

[0045] Working principle: When in use, the drive motor 4 works. The drive motor 4 will drive one set of rotating rods 17 to rotate. Since the two sets of transmission gears 16 are meshed with each other, the two sets of crushing rollers 2 will rotate in opposite directions, and the material will pass through the gap between the two sets of crushing rollers 2, thereby crushing the material;

[0046] The material crushed by the crushing roller 2 will fall into the screening plate 8. The screening plate 8 will screen the material. The qualified crushed material will pass through the screening plate 8 and enter the discharge shell 9, and finally be discharged through the discharge port 28. The unqualified crushed material will enter the subsequent unqualified material return assembly for return. When the drive motor 4 works, since the two sets of transmission gears 16 are meshed with each other, the connecting rod 18 will be driven to rotate. When the connecting rod 18 rotates, it will drive the transmission rod 19 to rotate. When the transmission rod 19 rotates, it will drive the transmission disk 5 to rotate. When the transmission disk 5 rotates, it will cooperate with the transmission strip plate 6 to make the screening frame 10 move left and right reciprocally, thereby improving the screening effect of the screening frame 10;

[0047] The unqualified crushed material will fall into the material receiving shell 11, and then fall into the return material box 22 under the action of its own gravity, and then enter the return material cylinder 15. Finally, it will fall back into the shell 1 through the return material pipe 14 under the lifting action of the spiral return material blade 12, realizing the return of the unqualified crushed material;

[0048] When the driving motor 4 works, it will drive the crushing roller 2 to crush and at the same time drive the spiral return material blade 12 to rotate, avoiding the need to install multiple driving devices, reducing the equipment cost. At the same time, when the driving motor 4 works, it will pull the material receiving shell 11 to rotate up and down reciprocally, which can assist the material on the material receiving shell 11 to enter the return material box 22.
