A concrete 3D printing head comprises a shell with a feeding port, a discharging nozzle is connected to the lower end of the shell, the upper portion of the shell is a large-diameter cylinder, the lower portion of the shell is a small-diameter cylinder, the middle of the shell is a conical cylinder, a whole integrated stirring shaft vertically penetrates through the interior of the shell, the surface of the upper section of the stirring shaft is connected with a large auger, and the surface of the lower section of the stirring shaft is connected with a small auger. The middle section of the stirring shaft corresponds to the conical barrel in the middle of the shell in position, the two ends of a spiral strip which is sleeved with the middle section of the stirring shaft in a suspended mode are connected with a large auger and a small auger respectively, the spiral caliber of the spiral strip is reduced from top to bottom to be in an inverted pagoda shape, and a stirring and pushing reinforcing mechanism is formed. According to the invention, the structure is reasonable, the augers with different specifications are arranged corresponding to the spaces with different sizes in the shell, and the spiral strip is arranged at the narrowing part of the conical barrel, so that the secondary stirring effect is good, concrete slurry is prevented from being separated, the thixotropy of the material is improved, the pushing and discharging are smooth, and blockage and stagnation at the narrowing bottleneck part are avoided.
一种混凝土3D打印头，包括带有进料口的壳体，出料喷嘴连接在壳体的下端，壳体的上部形状是粗径圆筒、下部是细径圆筒、中部则是锥形筒，整根一体的搅拌轴上下贯穿壳体的内部，搅拌轴的上段表面连接有大绞龙、下段表面连接有小绞龙，搅拌轴中段和壳体中部的锥形筒位置相对应，悬空套于搅拌轴中段的螺旋条两端分别连接大绞龙和小绞龙，且螺旋条的螺旋口径自上往下缩小呈倒宝塔状，形成搅拌推送加强机构。本发明的结构合理，对应壳体内部不同大小空间处布置有不同规格的绞龙，在锥形筒收窄处布置有螺旋条，发生的二次搅拌效果好，防止混凝土浆料离析，提高材料触变性，推送出料顺畅，不会在收窄瓶颈部位堵塞停滞。
