[0002] A tunnel boring machine (TBM), also known as a shield tunneling machine, is a specialized engineering machine for tunnel excavation. Modern TBMs integrate optics, mechanics, electronics, hydraulics, sensing, and information technology, and have functions such as excavating and cutting soil, transporting excavated material, assembling tunnel lining, and measuring and guiding. They involve multiple disciplines such as geology, civil engineering, mechanics, hydraulics, electrical engineering, control, and surveying. Moreover, they must be designed and manufactured in a "tailor-made" manner according to different geological conditions, and the reliability requirements are extremely high. TBMs are widely used in tunnel projects such as subways, railways, highways, municipal works, and hydropower projects.

[0003] Currently, most tunnel boring machines (TBMs) use conveyor belts to transport excavated blocks. However, conveyor belts have several problems. For example, during production, the conveyor belt is frequently affected by friction and wear from materials, leading to wear and breakage that requires regular replacement and maintenance, increasing maintenance costs. Furthermore, the conveyor belt cannot filter debris and moisture from the blocks, affecting the later use of the excavated blocks by the TBM. Therefore, a green tunnel construction TBM earthmoving mechanism is needed to address these issues. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

The support frame 201 is mounted on the main body 1. A first support plate 202 is fixedly connected to the top of the support frame 201. A first reinforcing plate 203 is fixedly connected to the top of the first support plate 202. The side of the carrying box 206 is fixedly connected to the first support plate 202. A conveying frame 207 is installed inside the carrying box 206. Multiple rollers 208 are arranged inside the conveying frame 207. An electric actuator 209 is installed inside the conveying frame 207. A gear set 210 is fixedly connected to the output end of the electric actuator 209. The gear set 210 is rotatably connected to the rollers 208.

[0027] The filter assembly 3 includes a connecting frame 301 and a filter tank 302. The connecting frame 301 is installed inside the main body 1, and the filter tank 302 is fixed on the connecting frame 301. An outlet 303 is provided at the bottom of the filter tank 302.

[0028] The conveying mechanism, consisting of a conveyor frame 207, an electric actuator 209, a gear set 210, and rollers 208, can transport materials with large single-piece weights or withstand large impact loads. Furthermore, there is a gap between every two rollers 208, which facilitates connection and filtration. Accumulation rollers 208 can be used to achieve the accumulation and conveying of materials. This conveyor has a simple structure, high reliability, and is convenient to use and maintain.

[0029] Among them, the roller 208 is arranged along the extension direction of the conveyor frame 207. There are two support frames 201, which are symmetrically distributed on both sides of the main body 1. The support frame 201 is located between the two support frames 201. The top of the support frame 201 is fixedly connected to the second support plate 204. The top of the second support plate 204 is fixedly connected to the second reinforcing plate 205. The second reinforcing plate 205 is fixedly connected to the side of the bearing box 206. The side of the bearing box 206 is fixedly connected to the discharge box 211. The bottom of the discharge box 211 is provided with a discharge hole 212.

[0030] There are two connecting frames 301, which are symmetrically distributed at both ends of the main body 1. The filter tank 302 is located between the two connecting frames 301, and a sealing strip 304 is provided on the top of the filter tank 302.

[0031] Taking advantage of the easy connection and filtration between the rollers 208, the blocks excavated by the tunnel boring machine can be filtered for moisture and waste, which facilitates the transportation and stacking of blocks, improves the neatness of stacking, and avoids the impact of waste accumulation on the efficiency of block transportation during the transportation process.

[0032] In this embodiment, reference is made to Figure 1 and Figure 4As shown, the main body 1 includes a base frame 101, a conveying assembly 2 installed on the top of the base frame 101, a filtering assembly 3 installed inside the base frame 101, four base plates 102 fixedly connected to the bottom of the base frame 101, a protective frame 103 fixedly connected to the top of the base frame 101, a control box 104 fixedly connected to the side of the protective frame 103, a display screen 105 fixedly connected to the side of the control box 104, a start switch 106 and a physical button 107 provided on the side of the control box 104, the start switch 106 and the physical button 107 are used to control electrical control equipment such as the electric actuator (209).

[0033] The base plate 102 enhances bottom stability, while the protective frame 103 can prevent blocks from falling accidentally during transportation, thus avoiding them from falling to the ground and causing injury to workers.

[0034] In this solution, a tunnel green construction shield machine earthmoving mechanism is used by placing the excavated blocks on a conveying mechanism consisting of a conveying frame 207, an electric actuator 209, a gear set 210, and multiple rollers 208. The electric actuator 209 drives the gear set 210 to rotate, which in turn drives each roller 208 to rotate simultaneously, thereby conveying the blocks. During the conveying process, since there is a gap between every two rollers 208, it is easy to connect and filter, so the excavated blocks can be filtered for moisture and waste. The filtered material enters the filter tank 302 for centralized collection and is discharged from the outlet 303. The filtered blocks are then conveyed to the discharge box 211 and discharged from the discharge hole 212.
