For those of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0030] In the construction process of tunneling, the open tunneling machine (TBM) uses the front end shield to cut the stratum and expose the surface without supporting. The surface without supporting will fall a large amount of spoil under the factors of mechanical disturbance and loss of stability of the surrounding rock of the stratum, which is an inevitable construction feature of the open tunneling machine. The fallen spoil will accumulate at the bottom of the arch under the action of gravity. If the spoil pile formed without spoil removal treatment, it will affect the efficiency of the tunneling machine step advancing, and seriously affect the construction progress. At present, a spoil conveying belt is arranged below the main beam of the tunneling machine, and the spoil is put into the feeding port of the spoil conveying belt by manual operation, which not only wastes manpower, but also has low work efficiency.

[0031] To solve the above technical problems, the embodiments of the present application provide an auxiliary spoil removal mechanism.

[0032] Reference Figure 1 , Figure 2 and Figure 5As shown, the auxiliary slag discharge mechanism provided by the embodiment of the application comprises a lifting assembly, a muck conveyor 100 located below the main slag discharge mechanism of the open tunneling machine, and a hinged part 108 hinged to the open tunneling machine; the lifting assembly is used to adjust the height of the end of the feeding port of the muck conveyor 100; the muck conveyor 100 is used to convey the slag entering the feeding port thereof and the slag output by the main slag discharge mechanism to the rear of the auxiliary slag discharge mechanism; the muck conveyor 100 is provided with a tiltable scraper assembly at the end of the feeding port.

[0033] The muck conveyor 100 is located below the main beam 114 of the tunneling machine; the front end of the main beam 114 is provided with a machine head conveyor belt, which is used to convey the muck generated by the machine head of the tunneling machine to the muck conveyor 100; the muck conveyor 100 is provided with a scraper assembly at the end of the feeding port; the main beam 114 is provided with a lifting assembly connected with the muck conveyor 100, which is used to adjust the height of the end of the feeding port of the muck conveyor 100.

[0034] The muck conveyor 100 is provided with the hinged part 108 connected with the main beam 114 at the end close to the discharge port. The lifting assembly comprises a lifting support 109 fixed to the main beam at the upper end, and a first telescopic part 110 provided at the lower end of the lifting support 109 and connected with the muck conveyor 100 at the telescopic end, which is used to adjust the height of the end of the feeding port of the muck conveyor 100.

[0035] The working principle of the embodiment of the application is as follows:

[0036] The embodiment of the application connects the muck conveyor 100 with the main beam 114 of the tunneling machine through the lifting assembly, and adjusts the height of the feeding port of the muck conveyor 100 through the telescopic function of the first telescopic part 110. The scraper assembly at the feeding port of the muck conveyor 100 is in close contact with the bottom of the tunnel arch through the first telescopic part 110. When the tunneling machine moves forward, the auxiliary slag discharge mechanism moves, and the scraper assembly of the embodiment of the application is inserted into the muck pile along the surface of the bottom of the tunnel arch. The scraper assembly moves in the direction away from the muck conveyor 100 along the tunnel path, and thus relative movement is generated, so that the muck enters the feeding port from the scraper assembly, and the muck conveyor 100 can realize automatic discharge.

[0037] The first telescopic part 110 at the lower end of the lifting support 109 can be telescopic according to the accumulation height of the muck at the bottom of the tunnel arch, so as to adjust the height of the feeding port of the muck conveyor 100. In this way, it can be ensured that the scraper assembly is always in the best working position, and the muck is not missed or accumulated. The height adjustment of the feeding end of the muck conveyor 100 can be realized through the setting of the first telescopic part 110, so that the slag discharge and feeding device can adapt to the changes of the slope and the change of the turning radius of the tunnel, and the application range of the slag discharge and feeding device can be greatly improved.

[0038] The technical effects that the embodiments of this application can produce are:

[0039] Firstly, in this embodiment, a muck conveyor 100 is installed below the main beam 114 of the tunneling machine, and a shovel assembly is equipped at one end of the feed inlet. The shovel assembly can automatically push the muck accumulated at the bottom of the arch into the feed inlet of the conveyor, realizing automated muck loading. Therefore, this embodiment greatly improves the efficiency of muck handling, ensuring that the tunneling machine is not affected by muck accumulation during its advancement, thereby accelerating the construction progress.

[0040] Secondly, the embodiments of this application, through the automated shovel assembly and the slag conveyor 100, almost completely replace the manual material loading operation. Workers only need to perform a small amount of monitoring and maintenance work, which greatly reduces the demand for manpower, lowers labor intensity, improves the working environment for workers, and also enhances construction safety.

[0041] Thirdly, in this embodiment, the telescopic end of the first telescopic component 110 is connected to the slag conveyor 100, which allows for flexible adjustment of the height of the slag conveyor 100's inlet according to the slag accumulation at the bottom of the arch. This embodiment ensures, through the above design, that the shovel assembly can always effectively push slag into the conveyor, avoiding slag leakage or accumulation due to height mismatch, and further improving the efficiency of slag handling.

[0042] As an optional implementation method, refer to Figure 1 , Figure 2 As shown, the shovel assembly of this application embodiment includes a front shovel 101 and a rear shovel 102 connecting the front shovel 101 and the feed inlet; the front shovel 101 has an arc-shaped structure and can fit against the arc surface of the channel arch bottom. The front shovel 101 is driven to move away from the slag conveyor 100 along the channel path so that the slag can move from the front shovel 101 to the rear shovel 102. A rotating scraper assembly is installed on the rear shovel 102 to push the slag into the feed inlet.

[0043] The shovel assembly of this application embodiment includes a front shovel 101 and a rear shovel 102 connecting the front shovel 101 and the feed inlet, wherein the front shovel 101 has an arc-shaped structure and can fit against the arc surface of the channel arch bottom.

[0044] It should be noted that the front shovel plate 101 in this embodiment of the application has an arc-shaped structure, and the radius of the arc-shaped structure can be consistent with the radius of the channel. Therefore, the lower surface of the front shovel plate 101 can fit against the arch bottom of the channel.

[0045] It should be noted that the radius of the arc-shaped structure can also be smaller than the radius of the channel. This application does not impose any special limitations on this embodiment, and those skilled in the art can make the selection as needed.

[0046] The working principle of this application embodiment:

[0047] When the tunneling machine advances, it drives the auxiliary muck removal mechanism to move synchronously. In this embodiment, the front shovel 101 can insert into the muck pile along the surface of the arch bottom. The front shovel 101 is driven to move along the channel path, so the muck and the shovel assembly will have relative movement. The muck will gradually slide from the front shovel 101 onto the rear shovel 102, forming a continuous muck flow path. Since the rotating scraper assembly of this embodiment is installed on the rear shovel 102, after the muck slides from the front shovel 101 onto the rear shovel 102, the rotating scraper assembly installed on the rear shovel 102 starts to rotate, pushing the muck evenly into the feed inlet of the conveyor. The rotation speed of the rotating scraper assembly can be adjusted according to the flow rate and distribution of the muck to ensure that the muck can smoothly enter the conveyor. In addition, the rotational movement of the rotating scraper assembly not only helps to push the muck into the feed inlet, but also cleans the surface of the rear shovel 102, preventing muck residue from remaining on the shovel.

[0048] Compared to existing technologies, the technical effects achieved by the embodiments of this application are as follows:

[0049] This application provides an auxiliary muck removal mechanism that automatically feeds muck during tunnel construction, eliminating the need for manual muck loading below the main beam 114 of the tunnel boring machine. This not only effectively improves muck removal efficiency but also significantly enhances construction safety. Furthermore, the design of the shovel assembly and rotating scraper assembly in this application ensures timely and accurate muck removal, preventing muck accumulation from affecting the tunnel boring machine's forward movement and improving construction progress and quality. Simultaneously, the stability of automated operation guarantees consistent muck handling, improving the cleanliness of the tunnel interior.

[0050] As an optional implementation method, refer to Figure 1 , Figure 4 As shown, the rotating scraper assembly includes two rotating disks 103 mounted on the rear shovel plate 102 and close to the feed inlet. The two rotating disks 103 are symmetrically arranged about the extension direction of the slag conveyor 100. The rotating disks 103 are provided with scraper plates 104 extending radially. The rotating disks 103 are driven to rotate the scraper plates 104.

[0051] The rotating scraper assembly of this embodiment includes two rotating disks 103. The rotating disks 103, when driven to rotate, can cause the scraper plate 104 to move the slag and soil. It should be noted that a safety gap is provided between the two rotating disks 103 to avoid collision interference. The two rotating disks 103 rotate in opposite directions and are arranged on both sides of the feed inlet. The inner scraper plate 104 moves close to the feed inlet, pushing the slag and soil into the feed inlet.

[0052] It should be noted that the specific structure of the slag scraping plate 104 can be set by those skilled in the art as needed.

[0053] The technical effects that can be achieved by the embodiment of the present application are as follows:

[0054] The embodiment of the present application significantly improves the efficiency and accuracy of the slag loading by arranging two symmetrical rotating discs 103 and setting radially extending slag scraping plates 104 on each rotating disc 103, enhances the stability and reliability of the equipment, reduces the slag residue, reduces the equipment wear, and improves the safety and quality of the construction. The arrangement of the embodiment of the present application is particularly suitable for the construction process of the open-type tunneling machine, can efficiently and stably handle the slag under complex geological conditions, and ensures the smooth progress of the construction.

[0055] Referring to FIGS. 1 and 2, Figure 1 , Figure 4 As an optional embodiment, the slag scraping plate 104 is provided in multiple numbers and is arranged at intervals around the circumference of the rotating disc 103.

[0056] It should be noted that a plurality of slag scraping plates 104 are arranged at intervals around the circumference of the rotating disc 103 on each rotating disc 103, so that the rotating disc 103 forms a star wheel structure. The number of the slag scraping plates 104 can be set by those skilled in the art as needed.

[0057] For example, five slag scraping plates 104 are arranged on each rotating disc 103.

[0058] For example, three slag scraping plates 104 are arranged on each rotating disc 103.

[0059] The technical effects that can be achieved by the embodiment of the present application are as follows:

[0060] The embodiment of the present application improves the efficiency of the slag loading by the design of the plurality of slag scraping plates 104, ensures that the slag can be pushed into the feed inlet from multiple directions, and avoids the accumulation of the slag.

[0061] The design of the plurality of slag scraping plates 104 of the embodiment of the present application enables the rotating disc 103 to achieve multi-point pushing during rotation, that is, each slag scraping plate 104 can effectively move the slag at different positions. The multi-point pushing design of the embodiment of the present application ensures that the slag can continuously and stably enter the feed inlet, avoiding the problems of slag accumulation or jamming caused by insufficient number of slag scraping plates 104. In addition, since the rotating directions of the two rotating discs 103 are opposite, the inner slag scraping plates 104 move close to the feed inlet, and the outer slag scraping plates 104 move away from the feed inlet. The staggered movement of the plurality of slag scraping plates 104 enables the slag to form a stable flow path between the two rotating discs 103, further enhancing the continuity and stability of the slag pushing. Referring to FIGS. 1 and 2, Figure 1 ,Figure 4 As an optional embodiment, the rear scraper plate 102 is provided with a mounting plane 105 on both sides of the feeding port, and the mounting plane 105 is perpendicular to the opening direction of the feeding port. The rotation plane of the rotating disc 103 is parallel to the mounting plane 105.

[0062] The mounting plane 105 of the embodiment is provided on the rear scraper plate 102, and the mounting plane 105 is provided with a preset angle with the horizontal plane, that is, the mounting plane 105 of the embodiment is an inclined plane with an angle, and the lower part of the mounting plane 105 is close to the front scraper plate 101.

[0063] The rotation plane of the rotating disc 103 of the embodiment is parallel to the mounting plane 105, and the rotation plane also has a certain angle with the horizontal plane. The angle between the mounting plane 105, the rotation plane and the horizontal plane is not specially limited, and can be set according to the needs of those skilled in the art.

[0064] It should be noted that the mounting plane 105 can also be arranged horizontally.

[0065] The lower surface of the rotating disc 103 can be in close contact with the mounting plane 105, or a gap can be reserved between the lower surface of the rotating disc 103 and the mounting plane 105. When the lower surface of the rotating disc 103 is in close contact with the mounting plane 105, the lower surface of the rotating disc 103 and the mounting plane 105 are both provided as smooth surfaces to reduce the friction between them.

[0066] When a gap is reserved between the lower surface of the rotating disc 103 and the mounting plane 105, the rotating disc 103 does not rub against the mounting plane 105. In order to realize efficient slag scraping on the mounting plane 105, the lower surface of the slag scraping plate 104 can be in close contact with the mounting plane 105, and the slag scraping plate 104 has a certain height, which can push the slag to move when the slag scraping plate 104 rotates.

[0067] Technical effects of the embodiment:

[0068] The design of the mounting plane 105 provides a flat and stable mounting basis for the rotating disc 103, ensures the consistent pushing direction of the slag scraping plate 104, and avoids the accumulation or jamming of the slag. The embodiment ensures the smooth operation of the rotating disc 103 and the slag scraping plate 104 during the working process, reduces the risk of equipment damage caused by shaking or deviation. In addition, the embodiment can reduce equipment wear and tear, prolong the service life of the rotating disc 103 and the slag scraping plate 104, and reduce maintenance costs.

[0070] Further, the front blade 101 of the embodiment of the present application is hinged with the rear blade 102, and the second telescopic member 106 is arranged to push the front blade 101 to pitch. The second telescopic member 106 can be a hydraulic cylinder or other type of telescopic driving module.

[0071] It should be noted that the second telescopic member 106 drives the front blade 101 to pitch, so that the lower surface of the front blade 101 can be effectively attached to the arch bottom in the channel with slope, and the muck is loaded by the front blade 101.

[0072] The second telescopic member 106 is arranged on both sides of the extension direction of the muck conveyor 100.

[0073] Technical effects of the embodiment of the present application:

[0074] The front blade 101 can be flexibly adjusted according to the terrain change of the arch bottom, so that the muck is avoided to be left on the front blade 101, and the cleanliness of the tunnel is improved. In addition, the design of the linkage of the front blade 101 and the rear blade 102 enhances the overall coordination of the equipment, improves the efficiency of muck treatment, and ensures that the muck can be continuously and stably fed into the conveyor.

[0075] Reference Figure 1 , Figure 2 As an optional embodiment, the lifting assembly further includes a bottom support frame 111. The upper part of the bottom support frame 111 is fixedly connected with the tunneling machine main beam 114, and the bottom of the bottom support frame 111 is provided with a support table 112. The support table 112 is located below the muck conveyor 100, and is used to support the muck conveyor 100.

[0076] The bottom support frame 111 is arranged to support the muck conveyor 100, which is conducive to improving the stability of the muck conveyor 100.

[0077] Technical effects of the embodiment of the present application:

[0078] The support table 112 is located below the muck conveyor 100, and directly supports the muck conveyor 100, so that the muck conveyor 100 is not affected by the ground change during the working process. The design of the support table 112 ensures that the muck conveyor 100 can always maintain a stable working state.

[0079] Referring to Figure 3 As shown in the drawings, the slag conveyor 100 of the embodiment of the present application comprises a conveying box 113 and a scraper chain arranged in the conveying box 113; the rotating scraping assembly can push the slag into the feeding port of the conveying box 113, and the scraper chain is used to convey the slag to the discharging port of the conveying box 113.

[0080] In another aspect, the embodiment of the present application provides an open type heading machine, which comprises a heading machine girder 114 and an auxiliary slag discharging mechanism; the front end of the heading machine girder 114 is provided with a heading machine head.
