The invention relates to the technical field of tunneling equipment, and discloses a shield machine cutterhead and a control method thereof, which include a cutterhead shell, an outer cutterhead is installed on the cutterhead shell, and at least two inner cutterheads are arranged inside the outer cutterhead. The cutterhead, the inner cutterhead includes a first-level inner cutterhead and a second-level inner cutterhead, the outer cutterhead and the inner cutterhead are equipped with main knives, the inner cutterhead is provided with leak holes, and the cutterhead shell is equipped with The transmission assembly connected to the inner cutterhead. The inner cutterhead is connected to the telescopic assembly through the transmission assembly. The transmission assembly includes a rotating connector. Through the multi-stage inner cutterhead and telescopic assembly, the cutterhead of the shield machine can be flat. The cutting can also be multi-level step cutting, so that it can adapt to different soil properties and work requirements, and the height between steps can be selected according to the actual situation of the rock and soil layer; when multi-level step cutting, the adjacent cutter head can be rotated In the opposite direction, the efficiency of rock formation breaking is improved, thereby improving the efficiency of excavation.
Description
technical field [0001] The invention relates to the technical field of tunneling equipment, in particular to a shield machine cutter head and a control method thereof. Background technique [0002] The cutter head of the current shield machine has a disc-shaped planar structure, and the cutter is set on the cutter head. During the excavation process, the shield machine is pushed forward as a whole, and the cutter cuts the front soil layer. The main excavation of the cutter head The cutters on the surface and the cutter head are located on the same plane, and the cutter head and the cutter directly bear the overall grinding force of the tunnel rock formation at the same time, resulting in the main force-bearing surface of the cutter head and the cutter bearing greater stress and serious wear, which is not conducive to The increase in tunneling speed will also reduce the service life of the cutter head and the cutter, and the current planar structure cutter head is relatively ...
