[0004] However, existing foamed concrete construction often employs step-by-step manual operation or simple mixing equipment. As a result, problems such as foam bursting and uneven distribution are prone to occur when foam and cement paste are mixed manually, leading to large fluctuations in concrete density and unstable strength. At the same time, it is difficult to control the thickness and flatness when manually pouring and placing the material. Therefore, solutions are needed. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art: the construction of foamed concrete often adopts step-by-step manual operation or simple mixing equipment, which easily leads to foam rupture and uneven distribution when foam and cement paste are manually mixed, resulting in large fluctuations in concrete density and unstable strength. At the same time, it is difficult to control the thickness and flatness when manually pouring and placing the material.

[0042] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0043] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0044] Example 1, as Figure 1-4As shown, the base 1 has multiple rollers 101 at the four corners of its bottom, made of polyurethane material, with a braking function, which gives the device good mobility and operational stability. The conveying structure includes a conveying pipe 102 fixed to the top of the base, and a conveying motor 1021 is installed on its outer surface through the frame, forming a spiral extrusion pumping system that can convey foamed concrete continuously and stably with low disturbance and prevent foam from bursting. The mixing structure includes a mixing chamber 103 connected to the top of the conveying pipe 102 through a pipe, and a feeding port 1031 is provided on its top for easy manual or mechanical addition of dry materials.

[0045] In this embodiment, cement and water are injected into the feeding port 1031, and the foaming device 2031 is started. The foaming agent in the foaming agent tank 203 is mixed with compressed air to generate micro foam. The flow rate is controlled by the foam transmission pipe 2032 and injected into the feeding port 1031 through the regulating valve 2033. The foam mixes with the cement in the conveying pipe 102. The stirring motor 1032 drives the stirring rod 1033 to perform low-speed stirring inside the mixing chamber 103 to avoid foam breakage and form uniform foam concrete. The conveying motor 1021 drives the drive shaft 1022 to rotate the outer surface of the conveying blades 1023. The mixed material inside the mixing chamber 103 is conveyed through the conveying hose 1024 and the material distribution head 1025. Through dynamic stirring and foam injection technology, premature foam breakage is avoided, ensuring that the foam concrete has a consistent density.

[0046] Example 2, as Figure 1-4 As shown, the conveying structure includes a drive shaft 1022, which is fixedly mounted at the output end of the conveying motor 1021 and installed inside the conveying pipe 102 via a sealing ring bearing. A conveying blade 1023 is fixed to the outer surface of one end of the drive shaft 1022. A conveying hose 1024 is located at one end of the conveying pipe 102, and its end is equipped with a cloth head 1025. In the mixing structure, the stirring motor 1032 is fixed to the top of the mixing chamber 103 via a frame, and its output end is connected to a stirring rod 1033. This stirring rod 1033 has multiple blades to ensure thorough and uniform mixing of the raw materials. Furthermore… The support frame 2 not only securely connects the base 1 and the mixing chamber 103, but also has slots 201 at symmetrical positions for installing guide rods 2022. The foaming agent tank 203 is placed on top of the support frame 2, and a foaming device 2031 and a regulating valve 2033 are installed. The latter introduces foam into the mixing chamber 103 through the foam transmission pipe 2032. The regulating motor 202 is fixed to the top of the support frame 2 through the frame body. The threaded rod 2021 at its output end cooperates with the mounting frame 2023 to enable the fabric head 1025 to move precisely in the vertical direction. The guide rod 2022 provides the necessary stability and positioning support.

[0047] In this embodiment, by driving the adjustment motor 202 to work, the threaded rod 2021 drives the mounting bracket 2023 on the outer surface to move along the guide rod 2022, thereby adjusting the height of the fabric head 1025 inside the mounting bracket 2023. This, in conjunction with the roller 101 at the bottom of the base 1, moves the fabric head to adjust the height, thereby reducing the need for manual leveling.

[0048] Working principle: During operation, cement and water are injected into the feeding port 1031, activating the foaming device 2031. The foaming device 2031 mixes the foaming agent in the foaming agent tank 203 with compressed air to generate fine foam. The flow rate is controlled through the foam transmission pipe 2033 and injected into the feeding port 1031 via the regulating valve 2033. The foam mixes with the cement in the conveying pipe 102, and works in conjunction with the mixing motor 1032, driving the mixing rod 1033 to perform low-speed mixing inside the mixing chamber 103. This prevents foam breakage and forms uniform foamed concrete. The working mechanism also works in conjunction with the conveying motor 1021, causing the drive shaft 1... 022 drives the outer surface of the conveying blades 1023 to rotate, and the mixed material inside the mixing chamber 103 is conveyed through the conveying hose 1024 and the material distribution head 1025. Through dynamic mixing and foaming injection technology, the foam is prevented from breaking prematurely, ensuring that the density of the foamed concrete is consistent. In addition, by driving the adjustment motor 202 to work, the threaded rod 2021 drives the mounting frame 2023 on the outer surface to move along the guide rod 2022, thereby adjusting the height of the material distribution head 1025 inside the mounting frame 2023. This, together with the rollers 101 at the bottom of the base 1, moves to adjust the material distribution height, thereby reducing the need for manual leveling.

[0049] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
