RECTANGULAR SHIELD TUNNELING MACHINE PROVIDED WITH ANTI-SOIL ACCUMULATION DEVICE

摘要

A rectangular shield tunneling machine provided with an anti-soil accumulation device, said machine comprising a machine head (5), a connecting body (3) and a machine body (1), wherein the connecting body (3) is fixedly connected with the machine head (5), the machine body (1) is disposed on the side of the connecting body (3) away from the machine head (5), a plurality of air cylinders (2) are mounted on the machine body (1) in a surrounding manner, driving ends of the air cylinders (2) are fixedly connected with the connecting body (3), a conveying pipe (4) is mounted on the side of the connecting body (3) close to the machine body (1) and communicates with the machine head (5) and the connecting body (3), a pair of first cutter heads (7) and a pair of second cutter heads (9) are mounted on the machine head (5), the first cutter heads (7) and the second cutter heads (9) are arranged in a staggered manner, and a plurality of cutting blocks (11) are mounted on the first cutter heads (7) and the second cutter heads (9). By folding and stretching plate surfaces at edges of the shield tunneling machine, soil can be dispersed and can be broken into small piece structures, thereby preventing the progress of the shield tunneling machine from being affected, and providing users with a rectangular shield tunneling machine provided with an anti-soil accumulation device.
