Milling and excavating head of milling excavator
The invention discloses a milling and excavating head of a milling excavator. The milling and excavating head comprises a rack and a milling excavator head fixed on the rack, and rotating assemblies for rotationally stirring and mixing a curing agent and a soil body are mounted on the milling excavator head; each rotating assembly comprises spiral baffles, cylindrical bases and milling teeth, the cylindrical bases of the two rotating assemblies are fixed to the two ends of the milling excavator head, the two cylindrical bases are obliquely installed from the top of the milling excavator head to the bottom of the milling excavator head to form an included angle alpha, and the milling teeth installed on the two spiral baffles are oppositely distributed at intervals in a staggered mode; and when the milling excavator head rotates, it is guaranteed that one of the milling teeth of the two spiral baffles evenly mixes the curing agent and the soil body below a center line of the milling excavator head, when the milling excavator head is used for a deep foundation soil body, one of the milling teeth of the two spiral baffles can mill and excavate large hard stone blocks, and the problem that the part under the center line of the machine head of the milling excavator collides with stones is solved, advancing of the base is not blocked, and the construction progress is accelerated.
本发明公开了一种铣挖机的铣挖头，包括：机架、固定在机架上的铣挖机机头，铣挖机机头上安装有对固化剂和土体进行旋转搅拌混合的旋转组件。所述旋转组件包括螺旋挡板、筒状基部、铣刨齿，所述铣挖机机头的两端固定有两个旋转组件的筒状基部，两个筒状基部从铣挖机机头顶部向底部倾斜安装形成夹角α，使得两个螺旋挡板上安装的铣刨齿处于对向交错间隔分布；在铣挖机机头旋转时，保证两个螺旋挡板的其中一个铣刨齿对铣挖机机头中线下方的固化剂和土体进行均匀混合，在深层地基土体时，两个螺旋挡板的其中一个铣刨齿能对大型坚硬石块进行刨挖开，解决铣挖机机头中线正下方部位与石块发生撞击的问题，使基部前进不被阻挡，提高了施工进度。
