Description

Shield machine Technical Field The utility model relates to the technical field of shield machines, in particular to a shield machine. Background The shield machine is a special engineering machine for tunneling, and is constructed by a shield method, namely, the shield of a tunnel is constructed while tunneling, which is called a supporting segment, and is different from an open construction method. The shield tunneling machine integrates various operations such as excavation, support, propulsion, piling and the like, and is widely applied to projects such as railways, subways, highways, hydroelectric tunnels and the like. As a special tunneling device, the system is a complex engineering system integrating mechanical, hydraulic, sensing, information and other technologies. The front end cutterhead of the small shield machine is driven to be located at the central shaft, torque is small due to output of a single motor when the front end cutterhead is rotated, when the front end cutterhead encounters a high-strength obstacle, a driving system is damaged and even the whole machine is scrapped due to the fact that the cutterhead is blocked instantly due to insufficient torque, moreover, a soil outlet at the bottom is transmitted to a conveying belt through a packing auger, the structure is large, occupied space is large, other equipment layout is limited, and therefore the use of the shield machine is affected.
