[0028] In order to make the purpose, technical solution and advantages of the practical embodiment clearer, the technical solution in the practical embodiment is clearly and completely described. Obviously, the described embodiment is a part of the practical embodiment, not all of the embodiments. Based on the embodiments in this practical, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this practical.

[0029] The embodiment of the present application provides an aerated concrete mixer, which solves the problem that the aerated concrete mixer has only one discharge port at the bottom, making it difficult to perform maintenance and unloading in an emergency. When in use, the aerated concrete mixer is provided with multiple discharge ports, thereby accelerating the mixing efficiency.

[0030] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] Reference Figure 1-Figure 6 , an aerated concrete mixer, comprising: a mixing tank 1;

[0032] A plurality of discharge ports 5 are provided at the bottom end of the surface of the mixing tank 1, and a plurality of discharge portions 8 are provided at the bottom end of the surface of the mixing tank 1. The discharge portion 8 includes a fixed frame 81, and the fixed frame 81 is connected to the mixing tank 1 on the side close to the mixing tank 1, and a push-pull rod 84 is provided on the side of the fixed frame 81 away from the mixing tank 1. A draw plate 85 is provided at the top of the fixed frame 81, and the bottom end of the draw plate 85 extends to the inner cavity of the fixed frame 81, and a sealing block 86 is connected to the side of the draw plate 85 close to the mixing tank 1, and the sealing block 86 coincides with the discharge port 5. A plug hole is provided on the surface of the draw plate 85, and the push-pull rod 84 passes through the draw plate 85 on the side close to the fixed frame 81 and is inserted into the inner cavity of the plug hole. A tension spring 82 is provided on the surface of the push-pull rod 84, and a limit plate 83 is fixedly provided on the surface of the push-pull rod 84, and the tension spring 82 is located in the inner cavity of the fixed frame 81.

[0033] The purpose of the sealing block 86 is to seal and block the discharge port 5 to prevent the material from being discharged through the discharge port 5 under normal circumstances, thereby affecting the normal operation of the equipment. At the same time, it can enable the mixing tank 1 to discharge the material quickly under maintenance.

[0034] Reference Figure 1-Figure 3 In a further embodiment, the front surface of the stirring tank 1 is connected to a discharge pipe 4, the bottom end of the stirring tank 1 is connected to a plurality of support columns 6, the surface of the support columns 6 is connected to a support plate 7, the support plate 7 is X-shaped, and a stepper motor 12 is connected to the center of the top of the support plate 7.

[0035] The support column 6 is provided to enhance the support of the device. Meanwhile, the support column 6 is made of metal material to enhance the pressure brought by the support column 6 while reducing the loss of the support column 6 .

[0036] Reference Figure 3 In a further embodiment, the top end of the output end of the stepper motor 12 penetrates into the inner cavity of the stirring tank 1 and is connected to a stirring rod 14. Rotating rods 3 are provided on both sides of the inner cavity of the stirring tank 1. The top and bottom ends of the rotating rod 3 penetrate the stirring tank 1. A pulley set 13 is provided at the bottom end of the rotating rod 3 and the top end of the output end of the stepper motor 12.

[0037] By setting a stepper motor 12, the output end of the stepper motor 12 and the stirring rod 14 are fixed. When the stepper motor 12 is operated by an external current, the output end of the stepper motor 12 generates a rotational force, which drives the stirring rod 14 to generate synchronous movement, providing a power source for the rotation of the stirring rod 14.

[0038] Reference Figure 3 In a further embodiment, the surface of the rotating rod 3 is connected to a stirring plate 9, a connecting strip 11 is connected to the side of the rotating rod 3 close to the inner cavity of the stirring tank 1, and a scraper 10 is connected to the outer side of the connecting strip 11.

[0039] The scraper 10 is provided to scrape off the concrete attached to the inner wall of the mixing tank 1 to prevent the concrete from being attached to the inner cavity of the mixing tank 1 for a long time, thereby causing the concrete to harden and affecting the normal operation of the equipment.

[0040] Reference Figure 4 In a further embodiment, a spray hole 15 is provided on the surface of the stirring plate 9, and a blocking net 16 is installed in the inner cavity of the spray hole 15.

[0041] The purpose of providing the blocking net 16 is to prevent concrete from entering the mixing plate 9 from the spraying holes 15 when the equipment is running, thereby damaging the mixing plate 9 and making it unable to spray water.

[0042] Reference Figure 1-Figure 3 In a further embodiment, the top end of the rotating rod 3 is connected to the external pipe 2, the top end of the stirring tank 1 is connected to the feed valve, and the rotating rod 3 is a cavity.

[0043] The purpose of setting the external pipe 2 is to connect it to an external water source, so as to facilitate the water spraying process of the equipment during operation and reduce the operator's operation.

[0044] Reference Figure 5-Figure 6 In a further embodiment, the outer side of the tension spring 82 is connected to the inner cavity of the fixing frame 81 , and the inner side of the tension spring 82 is connected to the limiting plate 83 .

[0045] The purpose of providing the tension spring 82 is to ensure that the push-pull rod 84 can be reset and to prevent the push-pull rod 84 from shaking or loosening, thereby reducing the fixing effect.

[0046] During use, the raw materials are poured into the mixing tank 1 through the feed valve, and at the same time, the external water source is connected through the external pipe 2. The stepper motor 12 is turned on by the external controller to drive the mixing rod 14 to rotate. Under the action of the pulley group 13, the rotating rod 3 is driven to rotate, so that the mixing plate 9 and the connecting strip 11 rotate, and the scraper 10 rotates. At the same time, the mixing tank 1 is rotated and sprayed with water through the spray hole 15, so that the raw materials are fully in contact with water. After the mixing is completed, it is discharged through the discharge pipe 4. At the same time, the concrete attached to the inner wall of the mixing tank 1 is scraped off by the scraper 10 and discharged; when an emergency situation occurs and the device needs to be repaired and discharged, the push-pull rod 84 is pulled backward. During this process, the tension spring 82 is deformed, so that the push-pull rod 84 is separated from the draw plate 85, and then the draw plate 85 is pulled out upward, so that the sealing block 86 is separated from the discharge port 5, and the mixing tank 1 is discharged.
