Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tunnel slag cleaning, in particular to a tunnel bottom crushing and slag cleaning machine. Background Technique
[0002] A TBM (Tunnel Boring Machine) is an efficient mechanical equipment for tunnel construction and is widely used in tunnel boring in fields such as subways, hydropower stations, highways, and railways. A large amount of muck is generated during the tunneling process of the TBM, and this muck needs to be cleaned in a timely manner to ensure the smooth progress and construction safety of the construction. During the tunneling process of the TBM, the muck enters the conveying system at the bottom of the tunnel through the cutter head and shield of the tunneling machine. The conveying system usually includes a belt conveyor or a screw conveyor to convey the muck from the bottom of the tunnel to the outside of the tunnel. Outside the tunnel, the muck can be further processed or directly used for landfill.
[0003] After the muck is conveyed out of the tunnel, the bottom of the tunnel needs to be cleaned to ensure the flatness and safety of the tunnel. The cleaning work is usually completed manually or mechanically, using equipment such as high-pressure water guns, pneumatic tools, or mechanical brushes. The working environment of manual operation is poor and the efficiency is low. It is rather laborious to transport the muck out of the tunnel, requiring a large amount of manpower and material resources, resulting in the inability to further improve the efficiency of tunnel construction.
[0004] Based on this, a tunnel bottom crushing and slag cleaning machine is now provided, which can eliminate the drawbacks of existing devices. Content of the Utility Model

[0028] In this embodiment, the soil slag will be placed inside the crushing component by the staff for crushing, and then conveyed to the lifting component on one side through the conveying component, received by the continuously rotating feeding hoppers 7 and then transferred to the ground to complete the slag cleaning work at the bottom of the tunnel;
[0029] In one embodiment, as Figure 2As shown in the figure, the blanking assembly includes a blanking plate 9, which is rotatably connected to one end of the lifting box 4 near the discharge port 5. One side of the lower end of the blanking plate 9 is fixedly connected with a plurality of springs 10, and the other end of the springs 10 is fixedly connected with one end of the adjacent lifting box 4. When the feed hopper 7 at the top is lowered along the rotation of the feed conveyor belt 8 to the other end of the lifting box 4, the soil and slag inside the feed hopper 7 will fall, and then fall above the inclined blanking plate 9 and fall from the discharge port 5 along the blanking plate 9. The feed hopper 7 continues to move downward, and then squeezes the blanking plate 9 from one side of the upper end of the blanking plate 9, expanding the gap between the upper end of the blanking plate 9 and the inner side of the lifting box 4 to facilitate its own passage. After the feed hopper 7 completely passes through, the blanking plate 9 is rebounded to its original position by the rebound of the spring 10 to continue receiving the soil and slag dropped by the next feed hopper 7.
[0030] In one embodiment, as Figure 2 shown, the upper end of the feed hopper 7 is provided with an inclined surface to facilitate passing through the gap between the upper end of the blanking plate 9 and the inner side of the lifting box 4.
[0031] In one embodiment, as Figure 4 shown, the crushing assembly includes a crushing box 1, the lower end of the crushing box 1 is fixedly connected with a crushing blanking port 13, the upper end of the crushing box 1 is fixedly connected with a crushing feed port 14, a crushing knife group 16 is arranged inside the crushing box 1, one side of the crushing box 1 is fixedly connected with a crushing motor 15, and the output end of the crushing motor 15 is in transmission connection with one end of the crushing knife group 16. After the soil and slag fall into the crushing box 1, they will be crushed by the rotating crushing knife group 16 while falling to the bottom of the crushing blanking port 13 for easy transportation.
[0032] In one embodiment, as Figure 4 shown, the crushing feed port 14 is provided with a wide mouth to facilitate receiving soil and slag.
[0033] In one embodiment, as Figure 4 shown, the crushing knife group 16 is composed of a plurality of annular crushing knives arranged in a crosswise combination for easy crushing.
[0034] In one embodiment, as Figure 3 shown, the conveying assembly includes a conveying pipe 2. One upper surface of one end of the conveying pipe 2 is fixedly connected with the lower end of the crushing blanking port 13, the other end of the conveying pipe 2 is fixedly connected with one side of the lower end of the lifting box 4, a spiral feeder 12 is rotatably arranged inside the conveying pipe 2, and a conveying motor 3 is fixedly connected to the end of the conveying pipe 2 far away from the lifting box 4. The soil and slag at the bottom of the crushing blanking port 13 will directly fall into one end of the conveying pipe 2. The conveying motor 3 is started to drive the rotating rod 11 and the spiral feeder 12 to rotate, and the dropped soil and slag are evenly transported into the lifting box 4.

[0036] The above embodiment discloses a tunnel bottom crushing and slag cleaning machine. After the soil slag falls into the crushing box 1, it will be crushed by the rotating crushing knife group 16 while falling to the bottom of the crushing discharge opening 13. The soil slag at the bottom of the crushing discharge opening 13 will directly fall to one end inside the conveying pipe 2. The conveying motor 3 starts to drive the rotating rod 11 and the screw feeder 12 to rotate, and uniformly transports the fallen soil slag into the lifting box 4. It is received by the continuously rotating feeding hopper 7 and then transferred to the ground. When the feeding hopper 7 at the top is descending along the rotation of the feeding conveyor belt 8 to the other end of the lifting box 4, the soil slag inside the feeding hopper 7 will fall at this time, and then fall above the inclined feeding plate 9 and fall from the discharge port 5 along the feeding plate 9. The feeding hopper 7 continues to move downward. Through the inclined surface setting of the feeding hopper 7, it squeezes the feeding plate 9 from one side of the upper end of the feeding plate 9, enlarging the gap between the upper end of the feeding plate 9 and the inner side of the lifting box 4 to facilitate its own passage. After the feeding hopper 7 completely passes, the feeding plate 9 is rebounded to its original position by the rebound of the spring 10 to continue receiving the soil slag dropped by the next feeding hopper 7.
