Abstract
The utility model discloses an extra-large planetary master-sub drill bit for a tunnel shield machine. A cylinder driving shaft (2) is coaxially arranged in a first cylinder shell (1), and is fixedly connected with a master drill bit (9). Spiral sub drill bits (13) are uniformly distributed on at least one circle coaxial with the master drill bit (9) on the cutting end face of the master drill bit (9). A disc body sub drill bit power motor seat (21) is sleeved on the middle part of the cylinder driving shaft (2). A hydraulic motor (22) is arranged on the disc body sub drill bit power motor seat (21), and is connected with the axial spiral sub drill bits (13) respectively. A hydraulic system drives the sub drill bits to rotate through the hydraulic motor respectively, so that the sub drill bits rotate and revolve along with the master drill bit at the same time to obtain working efficiency which is improved by more than ten times to dozens of times compared with that of a single drill bit. Moreover, the drill bits adopt two stages of units, so that the sizes of the drill bits can be enlarged, and a first unit can be arranged on a first section of cement pipe top pipe to excavate a pipe jacking tunnel. The extra-large planetary master-sub drill bit can be widely applied to the conventional shield system.
