[0045] like Figure 1-Figure 14 As shown, the present invention provides an anti-delay shield device, including a shield body mechanism and a conveying mechanism; the shield body mechanism includes a main body 1, a cutter disc 7 and a collecting assembly, the cutter disc 7 is arranged at the end of the main body 1, the collecting assembly is located in the main body 1, and a discharge port is formed, and the feed end of the conveying mechanism is located below the discharge port; the conveying mechanism extends along the excavation direction and has a conveying direction opposite to the excavation direction, the conveying mechanism includes a sand and gravel transfer assembly and a mud and water transfer assembly 9, the mud and water transfer assembly 9 is located below the sand and gravel transfer assembly, and a plurality of perforations are arranged on the sand and gravel transfer assembly to allow mud and water to leak down to the mud and water transfer assembly 9.

[0046] Compared with the prior art, the anti-delay shield device provided by the present invention has the following advantages:

[0047] The anti-delay shield device provided by the present invention can realize the excavation action of the whole shield device by the cutter head 7 arranged at the end of the main body 1, and by arranging a collecting component in the main body 1, and the collecting component is formed with a discharge port, and the feed end of the conveying mechanism is located below the discharge port, so when the cutter head 7 rotates to excavate the tunnel to produce mud and sand, the mud and sand enter the collecting component, and are discharged from the discharge port of the collecting component and fall on the conveying mechanism. Since the conveying mechanism has a conveying direction opposite to the excavation direction, the excavated mud and sand can be transported out.

[0048] During the transportation process, since the conveying mechanism in the present application includes a sand and gravel transfer component and a mud and water transfer component 9, and the sand and gravel transfer component is located above the mud and water transfer component 9 and is arranged with multiple perforations, during the transportation process, large sand and gravel particles are still retained in the upper sand and gravel transfer component for transportation, while smaller mud and sewage particles will pass through the perforations to the lower mud and water transfer component 9 for transportation. In this way, by separating the sand and gravel from the mud and sand for transportation, the blockage problem caused by mixed transportation is avoided, thereby ensuring the stability of the overall device during operation.

[0049] It should be noted that the upper mud and sand transport assembly in the present application can be connected to a separate drive structure, so that the movement process of the mud and sand transport assembly is not affected. In this embodiment, the mud and sand transport assembly can form a conveyor belt mechanism with the drive structure. The upper mud and sand transport assembly can directly use the motor to drive the rotating wheel to cooperate with the conveyor belt to realize the transportation of large particles of sand and gravel, and the lower mud and water transport assembly 9 is directly set as a bearing plate with a slope, which can not only receive the mud and water leaked from the upper layer, but also make the mud and water automatically flow to the lower place to complete the transportation.

[0050] Alternatively, if Figure 1-Figure 6 Combination Figure 9-12 As shown, the sand and gravel transfer assembly includes a main frame, a conveyor belt 914, a first driving member, a driving wheel 915 and a roller 1005; the driving wheel 915 is arranged at one end of the main frame, and the first driving member is connected to the driving wheel 915 to drive the driving wheel 915 to rotate; the conveyor belt 914 is arranged around the main frame and the driving wheel 915, and the roller 1005 is located at the other end of the main frame and abuts against the bearing surface of the conveyor belt 914.

[0051] The main frame can provide support for the conveyor belt 914, and can drive the driving wheel 915 to rotate through the first driving member, thereby forming a conveyor belt structure in conjunction with the conveyor belt 914 to achieve the transportation of sand and gravel.

[0052] The roller 1005 in the present application is a spindle structure, and the roller 1005 squeezes the conveyor belt 914 passing through, so that a pit is formed on the conveyor belt 914 passing through the surface of the roller 1005, and the pit is located below the discharge port, so that the sand and mud falling on the surface of the conveyor belt 914 are concentrated in the pit, thereby solving the problem that the existing conveying surface is a flat structure, and the sand and mud falling on the surface of the conveyor belt 914 are easy to flow to both sides, and thus can solve the problem of mud and sand flowing out from the side of the conveyor belt 914 to a certain extent.

[0053] It can be understood that, in the process of the conveyor belt 914 moving to the other side through the roller 1005, a plane is gradually formed, and the mud falling into the pit passes through the perforations of the conveyor belt 914 and enters the feed hopper 905, completing the separation of the mud and sand and gravel.

[0054] Alternatively, if Figure 9-12 As shown, the mud and water transfer assembly 9 includes a feed hopper 905, a conveying pipe 906 and a bracket 913; the feed hopper 905 is located below the feed end of the conveyor belt 914, the feed hopper 905 is formed with a discharge port, the conveying pipe 906 extends along the extension direction of the main frame, and one end of the conveying pipe 906 is connected to the discharge port, and the other end is used to discharge mud and water; a plurality of brackets 913 are arranged at intervals along the extension direction of the main frame, and the conveying pipe 906 is mounted on the bracket 913.

[0055] The present application can carry the leaked mud and water through the feed hopper 905, and can transfer and discharge the mud and water through the conveying pipe 906 connected to the feed hopper 905. Since the conveying pipe 906 has a certain length, the conveying pipe 906 can be supported by multiple brackets 913 arranged at intervals, thereby ensuring the smooth transmission of the conveying pipe 906.

[0056] Alternatively, if Figure 9-12 As shown, the main frame in the present application includes a side plate 901, a support frame 902 and a rotating roller 903; there are two side plates 901, both of which are arranged in parallel along the extension direction of the main frame, there are multiple support frames 902, and the multiple support frames 902 are all located between the two side plates 901, and are arranged at intervals along the extension direction of the main frame, and are alternately arranged with the bracket 913; the rotating roller 903 is rotatably connected to the support frame 902, and the rotating roller 903 abuts against the side of the conveyor belt 914 facing away from the bearing surface.

[0057] Since the sand and gravel transfer assembly in the present application forms a conveyor belt structure, in order to ensure the stability of the middle part of the conveyor belt 914, the present application arranges multiple support frames 902 at intervals in the extension direction of the main frame, and further connects rotating rollers 903 to the support frames 902, so that they can follow the rotation of the conveyor belt 914 when it is running, avoiding the problem of jamming or excessive friction affecting the movement of the conveyor belt 914.

[0058] It should be additionally explained here that in the present application, a connecting seat 904 is also installed on the outer side of the side plate 901, and the connecting seat 904 is installed in the outer ring body 201 described below, so as to achieve a stable connection between the main frame and the outer ring body 201.

[0059] Alternatively, if Figure 9-14 The mud and water transfer assembly 9 also includes a pipe body connector 907, a bend pipe 908, an end cover 909, a second driving member 910, a delivery rod 912 and a sealing plug 911; one end of the delivery pipe 906 away from the discharge port is connected to the pipe body connector 907, and the pipe body connector 907 forms a sewage discharge cavity, which is located below the delivery pipe 906, one end of the bend pipe 908 is connected to the pipe body connector 907, and the bend pipe 908 is located above the pipe body connector 907; the end cover 909 is connected to the end of the pipe body connector 907, and the end cover 909 forms a sewage discharge port corresponding to the position of the sewage discharge cavity, the sealing plug 911 is arranged to block the sewage discharge port, the second driving member 910 is connected to the end cover 909, the delivery rod 912 is arranged in the delivery pipe 906, and the outer wall of the delivery rod 912 is formed with a threaded guide portion.

[0060] The second driving member 910 in the present application is a motor, and the outer wall of the conveying rod 912 forms a threaded guide portion, so that the conveying rod 912 provided in the present application forms an augers structure to realize the transportation of mud and water.

[0061] The delivery end of the delivery pipe 906 is connected to a pipe body connector 907, an outlet is provided on the pipe body connector 907, and a curved pipe 908 is connected to the outlet. An end cover 909 is installed at one end of the pipe body connector 907, and a sewage outlet is provided on one side of the end cover 909, wherein the pipe body connector 907 expands downward to form a sewage discharge cavity, and a second driving member 910 is installed on the outer side of the end cover 909, and a delivery rod 912 is provided in the delivery pipe 906, and the delivery rod 912 is connected to the second driving member 910.

[0062] The second driving member 910 drives the conveying rod 912 to rotate, pushing the mud in the conveying pipe 906 to flow to the side of the pipe body connector 907. The elbow 908 is located above the pipe body connector 907. The pipe body connector 907 expands downward to form a sewage discharge cavity. The sand and gravel entering the pipe body connector 907 are easy to gather in the sewage discharge cavity formed by the downward expansion of the pipe body connector 907, and the muddy water in the upper layer is discharged through the elbow 908.

[0063] A sewage outlet is provided on one side of the end cover 909 and is located below the second driving member 910. During maintenance, the sand and gravel entering the interior of the tube body connector 907 can be cleaned by opening the sewage outlet. A sealing plug 911 is installed on the sewage outlet of the end cover 909. The sealing plug 911 is installed in the sewage outlet through threads. The sealing plug 911 can be opened to facilitate cleaning of the interior of the tube body connector 907.

[0064] It is necessary to add that, if Fig.14 As shown, the curved pipe 908 is connected to the feed hopper 905.

[0065] When in use, the length of the overall delivery pipe 906 is configured as needed, and different numbers of delivery pipes 906, pipe body connectors 907, second drive members 910, bent pipes 908 and other structures are installed to form a delivery channel. Each delivery pipe 906 is installed with a second drive member 910 and a delivery rod 912 to provide power for the movement of the mud transported in the corresponding delivery pipe 906.

[0066] The use of multiple second driving members 910 to drive the mud flow solves the problem that the existing mud is insufficiently powered during long-distance transportation, resulting in a slow mud flow rate near the outlet end of the pipeline, which is prone to sedimentation in the outlet end, thus causing blockage and retention of the outlet end.

[0067] At the same time, a conveying channel composed of multiple conveying pipes 906 is adopted, and the mud and sand inside the single-section conveying pipe 906 can be easily cleaned through the pipe body connector 907.

[0068] Alternatively, if Figure 1-Figure 5 As shown, the collecting assembly includes a conical bracket 6 and an aggregate component 10; the conical bracket 6 is arranged in the main body 1 and can rotate relative to the main body 1, and the cutter disc 7 is installed at one end of the conical bracket 6; the conical bracket 6 includes a connecting section and a conical section, the outer wall of the connecting section is fitted with the inner wall of the main body 1, the end of the conical section with a larger diameter is connected to the connecting section, and the diameter of the conical section gradually decreases from one end close to the connecting section to the other end, forming a discharge port; the aggregate component 10 is arranged below the discharge port, and the aggregate component 10 is located between the discharge port and the feed end of the sand and gravel transfer assembly.

[0069] In the present application, a cutter disc 7 is installed on one end of the conical bracket 6, and the cutter disc 7 is located at the port of the main body 1. The conical bracket 6 and the cutter disc 7 can be limited and installed through the first ring seat 2 and the second ring seat 3. After installation, the conical bracket 6 and the cutter disc 7 rotate synchronously, and the axes of the conical bracket 6 and the cutter disc 7 are colinear and rotate around the axis, so that tunnel excavation is achieved by the rotating cutter disc 7.

[0070] Alternatively, if Figure 4 Combination Figure 5 As shown, the inner wall of the conical section in the present application is formed with a spiral protrusion 601, and the collecting component 10 includes a fan-shaped groove 1001, an edge 1002 and a mounting plate 1004; the feed port of the fan-shaped groove 1001 corresponds to the discharge port 1003, and the size of the feed port is larger than the size of the discharge port 1003; the mounting plate 1004 is relatively arranged on both sides of the discharge port 1003, and the roller 1005 is rotatably connected to the mounting plate 1004; the edge 1002 is formed on the side of the fan-shaped groove 1001, and overlaps with the edge of the discharge port of the conical bracket 6.

[0071] The conical support 6 is a conical shell structure, and a spiral protrusion 601 is provided on the inner wall of the conical support 6.
