Description

Technical Field

[0001] This utility model relates to the field of soil and slag sampling technology, specifically to a shield tunneling soil and slag sampling device. Background Technology

[0002] The composition of tunnel boring machine (TBM) excavated soil is complex, potentially containing various chemical components such as organic matter, inorganic salts, and heavy metals. The content and treatment methods of these components directly affect the resource utilization and environmental protection of the TBM excavated soil. Furthermore, the generation of TBM excavated soil is related to multiple factors, such as ground instability, control of the TBM's advance speed, and cutterhead wear. These factors can all lead to changes in the quality and quantity of the TBM excavated soil. Therefore, inspecting the TBM excavated soil can promptly identify and address these problems, ensuring the smooth progress of TBM construction. On-site sampling of the TBM excavated soil is necessary before inspection.

[0003] For example, Chinese utility model patent with patent number CN202022500173.3 provides a soil sampler, including a telescopic sampling rod and a sampling shovel. The rod in the sampler can be taken out from the sleeve, and the sampling shovel can be detached from the sleeve, making it convenient to put each part into the toolbox and saving carrying space. By hollowing out multiple through holes on the sampling shovel, the permeability of the soil can be increased, the adhesion between the soil and the sampling shovel can be reduced, and the soil can be quickly separated from the sampling shovel after sampling.

[0004] However, most existing sampling devices can only sample soil and debris. When sampling soil and debris containing mud, it is inconvenient to squeeze out the water from the mud, resulting in a large amount of water in the soil and debris, which affects subsequent testing. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model proposes a shield tunneling soil and slag sampling device to solve the technical problem mentioned in the background art: existing soil and slag sampling devices are inconvenient to squeeze out the water from the soil and slag containing mud during the sampling process, resulting in a large amount of water in the soil and slag, which affects subsequent testing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a shield tunneling soil and debris sampling device, comprising:

[0007] The mounting cylinder has a mounting plate at one end and a drive rod hinged to the mounting cylinder. The drive rod can rotate within a first angle and a second angle.

[0008] A sampling shovel is hinged to the mounting plate, and a pressure plate is provided on one side of the mounting plate located inside the sampling shovel.

[0009] A first driving mechanism is mounted on the driving rod and connected to the sampling shovel to convert the rotation of the driving rod within a first angle into the rotational opening and closing of the sampling shovel; and

[0010] A second drive mechanism is mounted on the drive rod and connected to the pressure plate to convert the rotation of the drive rod within a second angle into the sliding of the pressure plate along the axis of the mounting cylinder.

[0011] In a preferred embodiment, a first handle is provided at the end of the mounting cylinder away from the mounting plate, and a second handle is provided at one end of the drive rod.

[0012] In a preferred embodiment, the sampling shovel has a drain outlet, and a filter screen is provided inside the drain outlet.

[0013] In a preferred embodiment, the first driving mechanism includes:

[0014] The linkage cylinder is slidably sleeved on the mounting cylinder along its axis;

[0015] The first pull rod has one end hinged to the linkage cylinder and the other end hinged to the drive rod; and

[0016] The second pull rod is hinged at one end to the linkage cylinder and at the other end to the sampling shovel.

[0017] In a preferred embodiment, the second drive mechanism includes:

[0018] A movable cylinder is slidably sleeved on the mounting cylinder along its axis, and the drive rod is hinged to the movable cylinder;

[0019] A push rod, slidably inserted into the mounting cylinder along its axis, has one end connected to the movable cylinder and the other end connected to the pressure plate; a baffle is provided on the push rod.

[0020] The elastic element has one end abutting against the baffle and the other end abutting against the inner wall of the mounting cylinder.

[0021] In a preferred embodiment, a groove is provided on the mounting cylinder along its axis, and the inner side of the movable cylinder passes through the groove and is fixedly connected to the push rod.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] When in use, the device can be controlled to rotate within a first angle. During the rotation of the drive rod, the sampling shovel is controlled to rotate and open and close through the first drive mechanism to sample the tunnel boring machine's excavated soil. After sampling is completed, the drive rod can be controlled to continue rotating. During the rotation of the drive rod within a second angle, the pressure plate can be controlled to slide along the axis of the mounting cylinder through the second drive mechanism to compact the excavated soil inside the sampling shovel. This allows the water in the mud inside the excavated soil to be discharged from the sampling shovel, facilitating the testing of the excavated soil after the water has been discharged and improving the accuracy of the test data.

[0033] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0034] Example:

[0035] like Figure 1 , 2As shown, this utility model provides a shield tunneling soil and debris sampling device, including an installation cylinder 101, an installation plate 104 at one end of the installation cylinder 101, a drive rod 302 hinged to the installation cylinder 101, the drive rod 302 being rotatable within a first angle and a second angle, a sampling shovel 201 hinged to the installation plate 104, a first drive mechanism connected to the sampling shovel 201 on the drive rod 302, the first drive mechanism converting the rotation of the drive rod 302 within the first angle into the rotation opening and closing of the sampling shovel 201, the first drive mechanism including a linkage cylinder 204 slidably sleeved on the installation cylinder 101 along its axis, a first pull rod 304 hinged to the linkage cylinder 204, one end of the first pull rod 304 being hinged to the drive rod 302, the linkage cylinder 204 also being hinged to a second pull rod 203, one end of the second pull rod 203 being hinged to the sampling shovel 201.

[0036] A first handle 102 is provided at the end of the mounting cylinder 101 away from the mounting plate 104, and a second handle 303 is provided at the end of the drive rod 302. In use, by holding the first handle 102 and the second handle 303, the drive rod 302 is rotated along its hinge point with the mounting cylinder 101 by pulling the second handle 303. Its initial rotation angle is the first angle. During the movement, the drive rod 302 drives the linkage cylinder 204 to slide on the mounting cylinder 101 through the first pull rod 304. During the sliding process, the linkage cylinder 204 can control the sampling shovel 201 to rotate along its hinge point with the mounting plate 104 to sample the soil.

[0037] like Figure 1 As shown, in this embodiment, the sampling shovel 201 has a drain outlet, and a filter screen 202 is installed inside the drain outlet. The water in the sampled soil can be drained through the filter screen 202, thereby avoiding excessive water content in the soil that would affect subsequent testing.

[0038] like Figure 2 , 3 As shown, in this embodiment, a pressure plate 402 is provided on one side of the mounting plate 104 located inside the sampling shovel 201. A second driving mechanism connected to the pressure plate 402 is provided on the driving rod 302. The second driving mechanism converts the rotation of the driving rod 302 within a second angle into the sliding of the pressure plate 402 along the axis of the mounting cylinder 101. The second driving mechanism includes a movable cylinder 301, which is slidably sleeved on the mounting cylinder 101 along its axis. The driving rod 302 is hinged to the movable cylinder 301. A push rod 401 is slidably passed through the mounting cylinder 101 along its axis. A groove 103 is formed on the mounting cylinder 101 along its axis. The inner side of the movable cylinder 301 passes through the groove 103 and is fixedly connected to the push rod 401. One end of the push rod 401 is connected to the pressure plate 402. A baffle 403 is provided on the push rod 401. One end of the elastic member 404 abuts against the baffle 403, and the other end abuts against the inner wall of the mounting cylinder 101.

[0039] During the rotation of the drive rod 302 within the first angle, the push rod 401 is unable to move due to the elastic force of the elastic element 404. At this time, the movable cylinder 301 and the mounting cylinder 101 are in a relatively fixed state, and the sampling shovel 201 can be opened and closed by controlling the movement of the drive rod 302. After the sampling shovel 201 is fully closed, the second handle 303 is pulled to make the drive rod 302 continue to rotate. Its rotation angle is the second angle. During the rotation of the drive rod 302, the movable cylinder 301 can slide on the mounting cylinder 101, thereby driving the push rod 401 to move and push the pressure plate 402 out to contact the soil, thereby squeezing out the water in the soil to reduce the water content of the soil and facilitate subsequent soil testing.

[0040] The specific usage and beneficial effects of this utility model are as follows:

[0041] When in use, the device can be controlled to rotate the drive rod 302 within a first angle. During the rotation, the drive rod 302 drives the linkage cylinder 204 to slide on the mounting cylinder 101 via the first pull rod 304. During the sliding, the linkage cylinder 204 controls the sampling shovel 201 to rotate and open via the second pull rod 203 to sample the tunnel boring machine's soil. After sampling, the drive rod 302 can be controlled to continue rotating. During the rotation of the drive rod 302 within a second angle, the movable cylinder 301 can be controlled to slide on the mounting cylinder 101, thereby driving the push rod 401 to move and compress the elastic element 404. This, in turn, controls the pressure plate 402 to slide along the axis of the mounting cylinder 101 to compact the soil in the sampling shovel 201. This allows the water in the mud inside the soil to be discharged from the sampling shovel 201, facilitating the testing of the soil after the water has been discharged and improving the accuracy of the test data.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
