Abstract

The invention provides a dual-mode ditching machine, and particularly relates to the technical field of ditch excavation. The dual-mode trenching machine comprises a main body frame, a stand column and a walking mechanism, and a hard rock excavation module and a soft rock excavation module are installed on the main body frame. The hard rock excavation module comprises a cutterhead arm, a wheel type cutterhead mounted on the cutterhead arm and a cutterhead arm driving mechanism which is connected with the cutterhead arm to drive the cutterhead arm to act so as to change the vertical position of the wheel type cutterhead; the soft rock excavation module comprises a cutting arm, a cutting roller installed on the cutting arm and a cutting arm driving mechanism which is connected with the cutting arm to drive the cutting arm to act so as to change the vertical position of the cutting roller. When a composite stratum is excavated, only one of the wheel type cutter head and the cutting roller needs to be controlled to work, the whole equipment does not need to be replaced, the problem that in the prior art, two kinds of equipment need to be switched for use, and consequently a large amount of time is consumed when the equipment is replaced is solved, the excavation efficiency can be greatly improved, and the operation cost can be greatly reduced.

Description

technical field [0001] The invention relates to the technical field of trench excavation, in particular to a dual-mode trencher. Background technique [0002] A trencher is a kind of equipment used for underground engineering operations, specifically, this equipment is used to excavate trenches in the ground. At present, the strata excavated in the actual operation process include both hard rock strata and soft rock strata. [0003] For the type of hard rock, the Chinese invention patent application with the application publication number CN112359899A discloses a wheeled cutter head hard rock trencher, which mainly includes a cantilever, a telescopic oil cylinder and a wheeled cutter head. The working end of the telescopic oil cylinder is connected to the cantilever or The wheel cutter head is connected, and a downward thrust is applied to the cantilever end of the cantilever or directly to the wheel cutter head through the telescopic oil cylinder, so that the cutter of the...
