Description

Technical Field

[0001] The utility model relates to the technical field of 3D printing concrete devices, and specifically relates to a novel concrete 3D printing device. Background Technique

[0002] The 3D printing concrete device is the key equipment to realize the 3D printing concrete technology. This device is mainly composed of a control system, a printing system, a material conveying system, etc. The control system is responsible for receiving design data, controlling the movement trajectory and speed of the printing system, and ensuring the printing accuracy and efficiency. The printing system stacks the pre-configured concrete material layer by layer through a nozzle to form the designed concrete structure. The material conveying system is responsible for conveying the concrete material from the storage device to the printing system to ensure the continuity of printing.

[0003] For example, a concrete 3D printer in Chinese Patent (CN219788702U) is characterized by including: a cylindrical barrel, a conical barrel, a flange, two barrel support components, two groups of mutually perpendicular guide rails, a guide rail frame, four X-axis running wheels, four Y-axis running wheels, and a gas distributor. The concrete 3D printer of this utility model has a simple structure, is easy to operate, can be transported at will. In addition, the printing material is not restricted, and local materials can be used, which is convenient, simple, and efficient, and has appropriate accuracy. In addition, the material feeding is uniform, and the diameter and shape of the discharge strip can be adjusted. Therefore, it can be applied to a rich variety of application scenarios. In addition, it also has a wide range of uses in public facility construction and other aspects.

[0004] The above solution still has the following technical deficiencies. The cylindrical barrel and the conical barrel of the above solution are both arranged on the guide rails, so the guide rails need to bear the weight of the cylindrical barrel, the conical barrel, and the concrete. When the device is printing concrete, a large amount of concrete is needed. When the cylindrical barrel and the conical barrel of the above solution are designed to be larger to load more concrete, the force required to drive the cylindrical barrel and the conical barrel to move is relatively large, and it is difficult to be pushed by manpower. When the cylindrical barrel and the conical barrel are designed to be smaller, the concrete needs to be frequently added to the device, which greatly affects the working efficiency. Based on this, a novel concrete 3D printing device is provided. Content of the Utility Model

[0040] The working principle of the above embodiment is as follows:

Then open the valve 203 and start the pump body 202. The pump body 202 pumps the concrete in the cylinder body 1 into the discharge pipe 201. Then the concrete enters the cavity through the hose 204. Finally, the concrete is ejected from the printing nozzle 8 under the action of gravity and the extrusion of other concrete, realizing the printing of concrete.
