[0002] Autoclaved aerated concrete is usually made by mechanically mixing siliceous materials, calcareous materials, water and various admixtures to form a slurry, which is then poured and molded. The green body is then divided and processed into autoclaved aerated concrete suitable for use. Bubbles will be generated during the production of concrete bricks, affecting the quality of the finished product. At this time, the bubbles in the concrete need to be eliminated.

[0003] Publication No. "CN211440432U" discloses an autoclaved aerated concrete block exhaust device, which uses a motor to continuously drive a vibrating rod to rotate and stir the concrete defoamer and concrete. The concrete defoamer can effectively control the generation of foam in the concrete system, making the concrete components denser and brighter. At the same time, the vibration motor is started to drive the vibrating rod at the bottom of the cross plate to vibrate to assist in defoaming, which can quickly eliminate bubbles in the concrete and avoid long-term vibration causing concrete stratification. However, there are still certain shortcomings in use.

[0030] The present technical solution sets up the application of a feeding box 3 and a driving motor 4. When in use, the bracket 1 is placed on a stable ground, and then an external power supply is turned on. The concrete that needs to eliminate bubbles is fed into the tank body 2 from the feeding port at the top of the tank body 2, and a powdered defoaming agent is further added into the feeding box 3.

After a period of time, the driving motor 4 is stopped, and the concrete in the tank body 2 is discharged from the discharge port at the bottom, thereby completing a series of operations.

[0031] Embodiment 2: The technical content disclosed in this embodiment is an improvement made on the basis of the above-mentioned embodiment 1. The existing device is not convenient for evenly spreading the defoaming agent inside the concrete mixing station when adding the defoaming agent, so that the defoaming agent is easy to accumulate in one place, thereby increasing the difficulty of mixing. The technical solution of this invention is as follows: Figure 1 and Figure 2 , Figure 6As shown, a material spreading assembly of an autoclaved aerated concrete block is disclosed, wherein the output end of a driving motor 4 is fixedly connected to a driving shaft 5, and a scraper 6 is fixedly connected to the outer wall of the driving shaft 5, and a disc 7 is fixedly connected to the bottom end of the driving shaft 5, and a feeding port 15 is provided on the disc 7, and a stirring shaft 9 is fixedly connected to the middle of the bottom end of the disc 7, a material spreading hopper 8 is nested on the stirring shaft 9, and a stirring rod 10 is fixedly connected to the outer wall of the stirring shaft 9, and two groups of scrapers 6 are symmetrically arranged about the driving shaft 5, and the scrapers 6 are located at the feeding box 3.

[0032] In this technical solution, Figure 1 As shown, by utilizing the arrangement of the scraper 6 and the spreading hopper 8, the device can drive the scraper 6 to rotate during operation, so that the powder attached to the inner wall of the feeding box 3 can be dropped to avoid waste caused by residue. At the same time, the defoaming agent in the feeding box 3 can be broken up to keep it in a loose state, thereby preventing agglomeration and clogging the feed port 15. At the same time, the defoaming agent can be evenly scattered in the tank body 2 through the centrifugal force generated by the rotation of the spreading hopper 8, thereby avoiding accumulation and uneven mixing, thereby reducing the workload of mixing.

[0033] Its use is as Figure 2 and Figure 6 The technical solution shown, first turn on the drive motor 4, so that the drive shaft 5 is driven to rotate by the drive motor 4, at this time the drive shaft 5 will drive the scraper 6 to rotate, stir the powdered defoamer in the feeding box 3 to avoid agglomeration, further the drive shaft 5 will drive the disc 7 to rotate, so that the gear block on the disc 7 is meshed with the driven gear 11, at this time the feed port 15 opened on the disc 7 will intermittently engage with the feed port 15 at the bottom of the feeding box 3, so that the defoamer in the feeding box 3 intermittently falls into the hopper 8 below in a certain amount, because the disc 7 is fixedly connected to the stirring shaft 9, so that the disc 7 drives the stirring shaft 9 to rotate when it rotates, at this time the stirring shaft 9 simultaneously drives the stirring rod 10 and the hopper 8 to rotate, through the action of centrifugal force, the defoamer in the hopper 8 is evenly scattered in the tank body 2, further the stirring rod 10 rotates, the defoamer is mixed with the concrete, thereby completing the exhaust.

[0034] Embodiment 3: The technical content disclosed in this embodiment is a further improvement based on the above-mentioned embodiments 1 and 2.

In order to further solve this technical problem, the technical solution of this invention is as follows: Figure 3-Figure 5 As shown, a reset knocking assembly of an autoclaved aerated concrete block is disclosed, in which a driven gear 11 is rotatably installed in a groove opened at the top of a tank body 2, and a knocking rod 13 is movably connected in the groove, a cam 12 is fixedly connected to the bottom of the shaft end of the driven gear 11, two groups of driven gears 11 are symmetrically arranged about a disc 7, and the driven gears 11 are meshed with the tooth blocks on the disc 7, the knocking rod 13 is an "L"-shaped structure, and two groups of knocking rods 13 are symmetrically arranged about the disc 7, and the positions of the knocking rods 13 and the cam 12 correspond, a compression spring 14 is connected between the knocking rod 13 and the inner wall of the tank body 2, and the knocking rod 13 and the tank body 2 form an elastic telescopic structure through the compression spring 14.

[0035] In this technical solution, Figure 3 As shown, by utilizing the arrangement of the cam 12 and the knocking rod 13, the cam 12 intermittently squeezes the knocking rod 13 when rotating, thereby pushing the knocking rod 13 to slide along the inner wall of the tank body 2 while squeezing the compression spring 14 to contract and reset, and then the elasticity of the compression spring 14 drives the knocking rod 13 to reset and knock, causing the tank body 2 to vibrate, further playing the role of assisting exhaust, improving product quality, and improving the density and strength of concrete.

[0036] Its use is as Figure 4 and Figure 5 The technical solution shown first rotates the disc 7 so that the tooth block on the disc 7 meshes with the driven gear 11, thereby driving the driven gear 11 to rotate. The driven gear 11 will further drive the cam 12 to rotate, and when the cam 12 is in contact with the knocking rod 13, the knocking rod 13 is squeezed, so that the knocking rod 13 slides along the inner wall of the tank body 2 and squeezes the compression spring 14 to contract. At this time, the cam 12 continues to rotate and separates from the knocking rod 13, and then drives the knocking rod 13 to reset through the elastic potential energy of the compression spring 14, knocks the tank body 2, and causes the tank body 2 to vibrate, and so on and so forth, further playing the role of exhaust.
