Description

Mixer car and 3D printer for construction including the same A mixer car and a 3D printer for construction are disclosed. More specifically, a mixer car and a 3D printer for construction are disclosed, which can manufacture and supply mortar for a 3D printer for construction, are capable of self-driving, and have the function of controlling the operation of the entire 3D printer for construction. Generally, large frame-structured equipment is primarily used for construction 3D printers to print large structures. However, these conventional construction 3D printers have the problem that installation takes a long time and the work procedure is complex because heavy equipment such as cranes must be used during the assembly and installation process. In addition, conventional frame-type 3D printers can only print from a fixed position, so the equipment must be disassembled and reinstalled to change the printing position. This process also inevitably requires the use of heavy equipment, and the reinstallation takes a long time, which has limitations in reducing work efficiency. Meanwhile, printing materials such as mortar supplied to construction 3D printers are generally manufactured and supplied in separate mixing equipment, which makes the material supply process inefficient and raises concerns about quality degradation during transfer between equipment. Considering these issues, there is a need for a construction 3D printer that can improve installation and operation efficiency by integrating the manufacturing and supply functions of mortar and ensuring mobility. FIG. 1 is a drawing for explaining the configuration and operating principle of a mixer car according to one embodiment of the present invention. FIGS. 2a to 2c are perspective views showing a construction 3D printer including the mixer car of FIG. 1 from different angles. Hereinafter, a mixer car according to one embodiment of the present invention and a construction 3D printer including the same will be described in detail with reference to the drawings. FIG. 1 is a drawing for explaining the configuration and operating principle of a mixer car (100) according to one embodiment of the present invention. Referring to FIG. 1, a mixer car (100) according to one embodiment of the present invention mixes raw materials (RM) to produce mortar and supplies the produced mortar to a printer head (250). The mixer car (100) may include a body (110), a hopper (120), a mixer (130), a water tank (140), a pump (150), an additional pump (not shown), and a drive wheel (160). The vehicle body (110) is a structure that forms the basic frame of the mixer car (100) and serves to support and fix components such as a hopper (120), a mixer (130), a water tank (140), and a pump (150) so that they can be mounted. Additionally, the vehicle body (110) includes a support structure capable of mounting a drive wheel (160) and a suspension system (not shown), and by combining the drive wheel (160) and the suspension system (not shown), the mixer car (100) can drive stably in an autonomous or remote control manner. If necessary, a power supply unit, a control module, a hydraulic drive system, or an electric drive system may be built into the vehicle body (110). Furthermore, the vehicle body (110) may be formed of steel plate, a lightweight alloy, or a composite material to ensure strength and durability, and anti-corrosion and waterproofing treatments may be applied to improve resistance to corrosion or impact in the external environment. A hopper (120) can be installed within the vehicle body (110) and configured to store raw materials (RM) used for 3D printing. Additionally, a stirrer (not shown) may be installed in the hopper (120) to prevent the supply from being disrupted due to the fine powder form of the raw materials (RM) aggregating or shifting to one side. The mixer (130) can be installed in fluid communication with the hopper (120) inside the vehicle body (110). Additionally, the mixer (130) may include a housing (131), a rotating shaft (132), and a drive motor (133). Specifically, the mixer (130) may be configured so that the rotating shaft (132) rotates within the housing (131) by the action of the drive motor (133). This allows for uniform mixing of the raw material (RM) for 3D printing, and the mixed raw material (i.e., mortar) can be stably supplied to the pump (150) through the outlet of the mixer (130). The drive motor (133) may be an electric motor or a hydraulic motor, and a mixing member in the form of a stirring blade or a screw is attached to the rotating shaft (132) to prevent aggregation of the raw material (RM) and enable continuous mixing. Additionally, the mixer (130) may be a continuous mixer capable of continuously mixing raw materials (RM) used in 3D printing, and unlike a fan mixer, it may have a structure in which raw materials (RM) are continuously fed and mixed. Additionally, the mixer (130) can stably produce mortar of a desired mixing ratio by c
