When the device is in use, the pull-out trolley 116 is first set into the installation cavity 113 along the inner slide 114, and then the external mortar device is started, and the mortar enters the spray gun 208 through the hose 209. When the deflection motor 210 drives the active swing arm 211 to rotate counterclockwise, the spray gun 208 rotates clockwise under the cooperation of the driven swing arm 214, the upper linkage arm 212 and the lower linkage arm 213. When the deflection motor 210 drives the active swing arm 211 to rotate clockwise, the spray gun 208 rotates counterclockwise under the cooperation of the driven swing arm 214, the upper linkage arm 212 and the lower linkage arm 213. When the spray gun 208 needs to be rotated, the rotating motor 201 is started and the spray gun 208 is rotated as a whole. When it is necessary to adjust the position of the moving car 109 and the injection mechanism 2 in the horizontal direction, the threaded rod 104 and the threaded rod 2 107 are driven to rotate independently or synchronously. When it is necessary to adjust the deflection angle of the molding base 131, the swing cylinder 128 is started, and when it is necessary to adjust the relative distance between the molding base 131 and the spray gun 208, the outer lifting cylinder 101 and the inner lifting cylinder 130 are started. After the printing is completed, the pull-out car 116 is pulled out of the installation cavity 113 to the outside by the handle 124, and then the pull-out car 116 is reset. Before the next printing, the cleaning motor 121 and the travel motor 122 are started. When the cleaning frame 119 moves along the outer slide 115, the brush 120 cleans the surface of the track frame 112 and the molding base 131, and sweeps the debris into the storage bin 123 for storage.

When the cleaning frame 119 moves along the outer slide 115, the brush 120 will clean the surface of the track frame 112 and the molding base 131, and sweep the debris into the storage bin 123 for storage. When printing is completed, in order to facilitate the pull-out cart 116 to be taken out, so as to replace it and print a new building, a handle 124 is also provided on the outside of the pull-out cart 116.

[0037] In this embodiment, in order to cooperate with the spray gun 208 to further improve the printing efficiency, a swing chassis 126 is movably arranged between the cantilever 125. When it is necessary to adjust the deflection angle of the molding base 131, a swing cylinder 128 is designed to cooperate with the deflection motor 210 to improve the processing efficiency. In order to adjust the height of the molding base 131 and cooperate with the external lifting cylinder 101 to adjust the vertical relative height of the spray gun 208, multiple groups of internal lifting cylinders 130 are designed.

[0039] In this embodiment, in order to drive the moving vehicle 109 and the ejection mechanism 2 to move freely in the horizontal direction, thereby realizing rapid 3D printing, a threaded rod 104 and a threaded rod 2 107 that cooperate with each other are designed.

[0040] See attached Figure 1 A transverse plate 110 is also installed between the outer lifting cylinders 101 on both sides of the track frame 112, and a plurality of groups of heating rods 111 are arranged on the inner wall of the transverse plate 110.

[0041] In this embodiment, during the printing process, in order to improve the drying efficiency of the slurry and further shorten the molding time, a heating rod 111 is designed.

[0042] See attached Figure 5 -Attached Figure 7 The output end of the deflection motor 210 is connected to an active swing arm 211, which is located between the front vertical plate 203 and the rear vertical plate 204. Two sets of symmetrical upper linkage arms 212 are movably installed at the other end of the active swing arm 211. Two sets of symmetrical lower linkage arms 213 are movably installed on the top of the swing seat 206. The upper linkage arms 212 and the lower linkage arms 213 on the same side are movably connected; the outer side of the front vertical plate 203 is movably connected to a symmetrical driven swing arm 214, and the bottom of the driven swing arm 214 is movably connected to the connection between the upper linkage arm 212 and the lower linkage arm 213.

[0043] In this embodiment: when the deflection motor 210 drives the active swing arm 211 to rotate counterclockwise, the spray gun 208 rotates clockwise in cooperation with the driven swing arm 214, the upper linkage arm 212 and the lower linkage arm 213. When the deflection motor 210 drives the active swing arm 211 to rotate clockwise, the spray gun 208 rotates counterclockwise in cooperation with the driven swing arm 214, the upper linkage arm 212 and the lower linkage arm 213. When the spray gun 208 deflects, in order to ensure that the center position of the nozzle is always located in the middle, that is, coaxial with the front vertical plate 203 and the rear vertical plate 204, the upper linkage arm 212 and the lower linkage arm 213 form a rhombus structure, and the lengths of the two groups of driven swing arms 214 are also kept consistent.

[0044] See attached Figure 5 and attached Figure 7 A hose 209 is provided on the outer wall of the spray gun 208, and the hose 209 is connected to an external device.

[0048] Working principle of the present invention: When the device is used, the pulling car 116 is first set into the installation cavity 113 along the inner slide groove 114, and then the external mortar equipment is started, and the mortar enters the spray gun 208 through the hose 209. When the deflection motor 210 drives the active swing arm 211 to rotate counterclockwise, the spray gun 208 rotates clockwise under the cooperation of the driven swing arm 214, the upper linkage arm 212 and the lower linkage arm 213. When the deflection motor 210 drives the active swing arm 211 to rotate clockwise, the spray gun 208 rotates counterclockwise under the cooperation of the driven swing arm 214, the upper linkage arm 212 and the lower linkage arm 213. When the spray gun 208 needs to be rotated, the rotating motor 201 is started and the spray gun 208 is rotated as a whole. When the position of the moving car 109 and the spray mechanism 2 in the horizontal direction needs to be adjusted, the threaded rod 104 and the threaded rod 217 are driven to rotate independently or synchronously. When the deflection angle of the molding base 131 needs to be adjusted, the swing cylinder 128 is started. When the relative distance between the molding base 131 and the spray gun 208 needs to be adjusted, the outer lifting cylinder 101 and the inner lifting cylinder 130 are started.
