[0002] TBMs are tunnel boring machines, which are divided into open-face tunnel boring machines and shield tunnel boring machines. They operate in parallel and continuously, performing tunneling, support, and muck removal. They are factory-produced, assembly-line tunnel construction equipment integrating mechanical, electrical, hydraulic, optical, and pneumatic systems. They offer advantages such as high tunneling speed, environmental friendliness, and high overall efficiency. They can construct long, deep tunnels in complex terrains that are difficult to achieve with traditional drill-and-blast methods. Their application in railway, hydropower, transportation, mining, and municipal tunnel projects in China is growing rapidly. During excavation, the excavated soil is transported out via conveyor belts or muck trucks. However, during transportation, rocks or soil inevitably fall to the ground, forming obstacles.

[0003] Existing TBM cleaning devices transfer the slag to a belt conveyor, but the slag needs to be turned during the transfer process, and the manufacturing cost of existing TBM cleaning devices is relatively high. Utility Model Content

[0004] The main purpose of this utility model is to solve the problem that the TBM cleaning device needs to be turned during the transfer of construction waste, and that the manufacturing cost of the existing TBM cleaning device is high, so as to provide a TBM cleaning device.

[0005] The objective of this utility model can be achieved by adopting the following technical solution:

[0006] A TBM slag removal device includes a support frame and a steering box fixedly connected to the support frame. A first conveyor belt is provided inside the support frame, with one end of the first conveyor belt extending into the steering box. A second conveyor belt is provided inside the steering box, with one end of the second conveyor belt located below it. A power output mechanism is provided on the steering box. A limit plate is fixedly connected to the inner wall of the support frame, and a baffle is fixedly connected to the inner wall of the support frame.

[0007] Preferably, a mating frame is fixedly connected to the back of the steering box, and the tension roller on the second conveyor belt is rotatably connected to the mating frame.

[0008] Preferably, the steering box has an input port on its side, through which the first conveyor belt passes.

[0009] Preferably, the steering box has an output port on its back, through which the second conveyor belt passes.

[0010] Preferably, the power output mechanism includes a protective cover fixedly installed on the front of the steering box and a baffle fixedly installed on the side of the steering box.

[0011] Preferably, the inner wall of the baffle box is rotatably connected to a transmission roller, and the lower surface of the steering box is rotatably connected to a mating roller.

[0012] Preferably, one end of the mating roller is fixedly connected to a first bevel gear, and one end of the transmission roller is fixedly connected to a second bevel gear that meshes with the first bevel gear.

[0013] Preferably, a drive motor is fixedly connected to the lower surface of the steering box, and the output end of the drive motor is fixedly connected to the mating roller.

[0014] Preferably, a drive roller is provided on the second conveyor belt, a first gear is provided at one end of the drive roller, and a second gear is fixedly connected to the end of the transmission roller away from the second bevel gear, wherein the first gear meshes with the second gear.

[0015] Preferably, the first conveyor belt is provided with a rotating roller, and both the rotating roller and the cooperating roller are provided with pulleys inside the protective cover.

[0016] The beneficial technical effects of this utility model are as follows: According to the TBM slag removal device of this utility model, the slag is input into the first conveyor belt from the right side of the baffle. The baffle restricts the position of the slag, making it difficult for the slag to slip off the first conveyor belt. The limiting plate restricts the position of the slag, making it difficult for the slag to enter the gap between the first conveyor belt and the support frame, which facilitates the conveying of the slag. The first conveyor belt inputs the slag into the second conveyor belt, and then the second conveyor belt transports the slag out, which facilitates the turning of the slag during transport. The drive motor drives the mating roller to rotate. The pulleys are connected to each other through belt transmission, thereby driving the rotating roller to rotate, and then driving the first conveyor belt to rotate. At the same time, through the cooperation of the first bevel gear and the second bevel gear, the transmission roller is driven to rotate. The transmission roller, through the cooperation of the first gear and the second gear, drives the drive roller to rotate, and then drives the second conveyor belt to rotate. By using a single drive motor drive device, the use of motors is reduced, thereby reducing the cost of the device. A reducer can be added to the output end of the drive motor to increase the output torque of the drive motor. Attached Figure Description

[0027] In this embodiment, as Figure 1 , Figure 2 , Figures 4-7As shown, the power output mechanism 5 includes a protective cover 501 fixedly installed on the front of the steering box 2 and a baffle 502 fixedly installed on the side of the steering box 2. A transmission roller 503 is rotatably connected to the inner wall of the baffle 502. A mating roller 504 is rotatably connected to the lower surface of the steering box 2. A first bevel gear 505 is fixedly connected to one end of the mating roller 504. A second bevel gear 506 meshing with the first bevel gear 505 is fixedly connected to one end of the transmission roller 503. A drive motor 507 is fixedly connected to the lower surface of the steering box 2. The output end of the drive motor 507 is fixedly connected to the mating roller 504. A drive roller 401 is provided on the second conveyor belt 4. A first gear 508 is provided at one end of the drive roller 401. The transmission roller 503 is located away from the second bevel gear.

A pulley 510 is provided on the rotating roller 301 and the mating roller 504 and inside the protective cover 501. The drive motor 507 drives the mating roller 504 to rotate. The pulleys 510 are connected to each other by a belt, thereby driving the rotating roller 301 to rotate, and then driving the first conveyor belt 3 to rotate. At the same time, through the cooperation of the first bevel gear 505 and the second bevel gear 506, the transmission roller 503 is driven to rotate. The transmission roller 503, through the cooperation of the first gear 508 and the second gear 509, drives the drive roller 401 to rotate, and then drives the second conveyor belt 4 to rotate.

[0028] In this embodiment, as Figures 1-7 As shown, the working process of the TBM slag removal device provided in this embodiment is as follows:

[0029] Step 1: The drive motor 507 drives the mating roller 504 to rotate. The pulleys 510 are connected to each other by belt transmission, thereby driving the rotating roller 301 to rotate, which in turn drives the first conveyor belt 3 to rotate. At the same time, through the cooperation of the first bevel gear 505 and the second bevel gear 506, the transmission roller 503 is driven to rotate. The transmission roller 503, through the cooperation of the first gear 508 and the second gear 509, drives the drive roller 401 to rotate, which in turn drives the second conveyor belt 4 to rotate.

[0030] Step 2: Input the excavated soil from the right side of the baffle 7 onto the first conveyor belt 3;

[0031] Step 3: The first conveyor belt 3 feeds the excavated soil onto the second conveyor belt 4, and then the second conveyor belt 4 transports the excavated soil out.

[0032] In summary, in this embodiment, according to the TBM slag removal device, the slag is fed onto the first conveyor belt 3 from the right side of the baffle 7. The baffle 7 restricts the position of the slag, making it difficult for the slag to slip off the first conveyor belt 3. The limiting plate 6 restricts the position of the slag, making it difficult for the slag to enter the gap between the first conveyor belt 3 and the support frame 1, facilitating the transport of the slag. The first conveyor belt 3 feeds the slag onto the second conveyor belt 4, and then the second conveyor belt 4 transports the slag out, facilitating the turning of the slag during transport. The drive motor 507 drives the mating roller 504 to rotate, and the pulleys 510 are positioned between them. The belt drives the rotating roller 301 to rotate, which in turn drives the first conveyor belt 3 to rotate. At the same time, the first bevel gear 505 and the second bevel gear 506 work together to drive the transmission roller 503 to rotate. The transmission roller 503 works with the first gear 508 and the second gear 509 to drive the drive roller 401 to rotate, which in turn drives the second conveyor belt 4 to rotate. The drive device is driven by a single drive motor 507, which reduces the use of motors and thus reduces the cost of the device. A reducer can be added to the output end of the drive motor 507 to increase the output torque of the drive motor 507.
