Multi-head excavator with main excavation head and auxiliary excavation heads
The invention relates to a canal excavation construction technology, in particular to a multi-head excavator with a main excavation head and auxiliary excavation heads, the multi-head excavator is composed of the main excavation head, the two auxiliary excavation heads and an excavator base, and the main excavation head and the auxiliary excavation heads are installed in front of the excavator base; each of the main excavation head and the auxiliary excavation heads consists of a spiral gravel drainage device, a semi-conical excavation cutter head and a excavation tooth claw, and is driven to rotate by a driving device installed in the excavator base, a sandy soil layer is cut while drilling is conducted, and sandy soil is driven by the spiral gravel drainage device to enter the excavator base, so that the tunneling operation is completed; and according to the multi-head excavator, leveling of the bottom of a ditch and integrated forming of a dam are conducted at the same time, it is possible to achieve a wide-section ditch stone hole through combination of the multi-head excavator, the engineering efficiency and quality are improved, and the construction cost is reduced. The multi-head excavator is wide in engineering adaptability, and can be used for excavating river canals meeting various construction and use requirements.
本发明涉及河渠挖掘施工技术，具体是一种具有主副挖掘头的多头挖掘机，该多头挖掘机由主挖掘头、2个辅助挖掘头和挖掘机座构成，所述主挖掘头和辅助挖掘头安装在所述挖掘机座前方；主挖掘头和辅助挖掘头均由螺旋砂石引流器、半圆锥挖掘刀盘和挖掘齿爪组成，由安装在挖掘机座内的驱动装置驱动旋转，边钻进边切割砂土层，砂土通过所述螺旋砂石引流器驱动进入挖掘机座内，完成掘进作业；本发明使沟渠底部的平整和堤坝一体成型同时进行，多头挖掘机的组合实现宽截面的沟渠石洞成为可能，提高了工程效率和质量，降低了施工成本。本发明工程适应性广，可用于开挖适用于各种施工和使用要求的河渠。
