Multi-head excavator with main excavation head and auxiliary excavation heads

Abstract

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.

Description

technical field [0001] The invention relates to the excavation construction technology of river canals, in particular to a multi-head excavator, which can excavate at the same time on a wider construction section when excavating ditches, and use the main and auxiliary excavating head devices of the multi-head excavator together, or multiple excavators The machine is used in parallel to make the bottom of the canal flat and the embankment to be formed quickly and efficiently, and it is suitable for the construction requirements of wide-section canals, which greatly improves the excavation efficiency. Background technique [0002] Canal excavation is a work that needs to be carried out in various industries, and canal excavation is often required in water conservancy, agriculture, municipal engineering and various building constructions. There are a lot of trenching equipment available. In the excavation process of the canal, traditional excavators are used for excavation. It ...

Problems solved by technology

[0004] This fast road canal forming machine is a bucket that replaces an excavator. Its volume and weight are restricted by the excavator, and it is only suitable for narrow and small ditches. During construction, only excavating teeth are used for excavation, and the speed is slow. Therefore, its operation Low efficiency, limited scope of use, unable to meet more construction needs
