This embodiment of the shield tunneling excavation continuous conveying device includes a conveyor belt 100 installed on one side of the shield machine. A screw conveyor on the shield machine conveys the excavation to the upper end of the conveyor belt 100. Drive rollers 103 are arranged on both sides inside the conveyor belt 100. Rotating shafts 104 are fixedly connected to both ends of the drive rollers 103. Support legs 101 are rotatably connected to the outer wall of each rotating shaft 104. In this embodiment, the conveyor belt 100 can transport the excavation discharged from the shield machine, and the support legs 101 support the equipment.

In this embodiment, the second sprocket 107 is driven to rotate by the rotation of the drive motor 108, and the first sprocket 105 is driven to rotate by the drive chain 106, thereby causing the transmission roller 103 on one side to rotate and drive the conveyor belt 100 to rotate to transport the slag.
[0032] It is worth noting that the first sprocket 105, drive chain 106, second sprocket 107 and drive motor 108 mentioned above are the drive components in this embodiment.
