[0002] With the development of the economy, the country has gradually increased its investment in infrastructure construction, especially in recent years, the construction of cross-sea tunnels has gradually increased. Shield machines are often used in the process of tunnel construction to speed up work efficiency. The construction method of the shield machine is that the tunnel boring machine builds a "shield" of the tunnel while excavating, which is different from the open construction method.

[0003] In existing tunnel construction, in-hole blasting is generally used to deal with boulders in front of shield machines. Generally, a device is set up on the road surface above the boulder to conduct detailed surveys and supplementary surveys to determine the location, depth and hardness of the boulder. A hole is drilled on the surface of the boulder using a drilling device, and explosives are placed in the hole for blasting. This method has a low safety factor and is complex to operate.

[0004] To this end, we propose a cutting device for isolated rocks in front of tunnels. Summary of the Invention

[0023] The rotating assembly 4 further includes a servo motor 1 41, the servo motor 1 41 is fixedly connected to the inner wall of the bottom of the housing 3, a rotating rod 42 is connected to the middle of the housing 3, the end of the inner rotating shaft of the servo motor 1 41 is connected with a drive belt 43, and the rotating rod 42 is driven by the drive belt 43. By starting the servo motor 1 41, the drive belt 43 can be driven to rotate, and the drive belt 43 drives the rotating rod 42 to rotate, so that the rotating rod 42 rotates in the circular housing 3.

[0024] The rotating rod 42 is rotatably connected to the housing 3. A pipe body 44 is provided in the middle of the rotating rod 42. A first bearing 47 is connected inside the pipe body 44. The inner wall of the first bearing 47 is in contact connection with the rotating rod 42, and the outer wall of the first bearing 47 is fixedly connected to the inner wall of the pipe body 44. The connecting rod 45 and the fixing plate 46 are integrally designed and fixedly connected to the pipe body 44. The included angle between the connecting rods 45 is 45 degrees, and the connecting rods 45 are obliquely downward and connected to the pipe body 44. The connecting rods 45 are provided on both sides of the pipe body 44. One side of the connecting rod 45 away from the pipe body 44 is connected to a fixing plate 46 for fixing to the housing 3, and the fixing plate 46 is fixedly connected to the housing 3. By providing the first bearing 47 inside the pipe body 44, when the rotating rod 42 rotates inside it, the connecting rods 45 on both sides can play a supporting role for the rotating rod 42, so that the rotating rod 42 is more stable when rotating.

[0025] One end of the rotating rod 42 is connected to a motor fixing plate 52, and the motor fixing plate 52 is fixedly connected to the rotating rod 42. A second servo motor 51 is provided inside the motor fixing plate 52, and the second servo motor 51 is fixedly connected to the motor fixing plate 52. One end of the inner rotating shaft of the second servo motor 51 is connected to a first bevel gear 53.
