[0002] Currently, weighing the excavated soil generated during tunnel boring machine (TBM) excavation is a crucial aspect of the operation. Traditional weighing methods use conveyor belts, but these methods are unsuitable for accurately measuring the weight of excavated soil in dynamic environments, affecting weighing accuracy. Furthermore, the continuous flow of excavated soil on the conveyor belt makes precise weighing impossible in a static state. Therefore, how to perform static weighing of excavated soil in segments to improve accuracy and reliability, and to manage the total amount of excavated soil, is a problem that needs to be solved by those in this field. Utility Model Content

[0003] The purpose of this utility model is to provide an intelligent slag weighing device that can perform static weighing of slag in a segmented manner, thereby improving the accuracy and reliability of weighing and enabling the management of the total amount of slag.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0006] The system includes a conveying system, a starting mechanism, a buffer mechanism, and a weighing system. After the excavated soil from the tunnel boring machine is transported to the conveying system via a screw conveyor, the conveying system can transport several excavated soil blocks to the buffer mechanism. The weighing system is located below the buffer mechanism. The buffer mechanism has at least a closed state and an open state.

[0010] Optionally, the starting mechanism includes a rotating wheel, a driven wheel, a conveyor belt, and a trigger switch. The rotating wheel is connected to the pulley of the conveying system. The driven wheel is located on the outside of the conveying system and is connected to the rotating wheel via the conveyor belt so that it can rotate synchronously with the rotating wheel. A drive block is provided on the conveyor belt. The trigger switch is fixed to the conveying system and is communicatively connected to the buffer mechanism. When the drive block contacts the trigger switch, it can control the state switching of the buffer mechanism.

[0011] Optionally, the drive block and the trigger switch are configured in a one-to-one correspondence, and the buffer mechanism switches to the closed state when the drive block contacts the trigger switch an odd number of times, and switches to the open state when the drive block contacts the trigger switch an even number of times.

[0031] The technical solution of this embodiment will be further described below with reference to the accompanying drawings and specific implementation methods.

[0032] like Figures 1-5 As shown, this embodiment provides an intelligent slag weighing device, including a conveying system 10, a starting mechanism 20, a buffer mechanism 30, and a weighing system 40. After the slag 300 of the tunnel boring machine 100 is transported to the conveying system 10 by the screw conveyor 200, the conveying system 10 can transport several slag blocks 310 of the slag 300 to the buffer mechanism 30. The weighing system 40 is located below the buffer mechanism 30. The buffer mechanism 30 has at least a closed state and an open state. In the closed state, the buffer mechanism 30 can receive the slag blocks 310. In the open state, the slag blocks 310 can fall from the buffer mechanism 30 to the weighing system 40 for weighing. The starting mechanism 20 is set on the conveying system 10 and can control the buffer mechanism 30 to switch between the closed state and the open state.

[0033] Specifically, in this embodiment, the buffer mechanism 30 and the weighing system 40 can divide the slag 300 transported by the conveying system 10 into several slag blocks 310 for segmented weighing. Furthermore, the slag blocks 310 can remain stationary on the weighing system 40 during weighing. Compared to dynamic weighing in the prior art, the results are more accurate and reliable. Further, the buffer mechanism 30 has at least a closed state and an open state. In the closed state, it can receive the slag blocks 310; in the open state, it can release the slag blocks 310 onto the weighing system 40 for weighing. This embodiment also includes a starting mechanism 20 to ensure the switching of the buffer mechanism 30's working state. This not only ensures that the weighing system 40 can perform segmented measurement of the slag 300, guaranteeing the accuracy of the measurement data and facilitating real-time summarization of the total weight of the slag 300, but also enables automated operation of the weighing process, avoiding manual intervention, achieving intelligent weighing, and improving weighing efficiency.

[0034] The specific structure of the intelligent slag weighing device in this embodiment is described below.

[0035] like Figure 1 and Figure 2 As shown, the intelligent slag weighing device in this embodiment includes a conveying system 10, a starting mechanism 20, a buffer mechanism 30, a weighing system 40, a PLC system 50, and a slag hopper 60. Specifically, the intelligent slag weighing device is mainly used for segmented static weighing of slag 300 in the tunnel boring machine 100. Optionally, the slag 300 of the tunnel boring machine 100 can be transported to the conveying system 10 by a screw conveyor 200, and under the action of the conveying system 10, several slag blocks 310 of the slag 300 are transported to the buffer mechanism 30 to achieve segmented processing. Exemplarily, the slag 300 is located inside the tunnel boring machine 100, and the screw conveyor 200 can transport the slag 300 from inside the tunnel boring machine 100 to the outside, until it is transported to the conveying system 10. Specifically, in this embodiment, the buffer mechanism 30 is located below the outlet of the conveying system 10, the weighing system 40 is located below the buffer mechanism 30, and the slag hopper 60 is located below the weighing system 40.

[0036] Furthermore, in this embodiment, the buffer mechanism 30 has at least a closed state and an open state. When in the closed state, the buffer mechanism 30 can receive the slag blocks 310. When in the open state, the slag blocks 310 can fall from the buffer mechanism 30 into the weighing system 40 for weighing. Furthermore, in this embodiment, the weighing system 40 has at least a weighing state and a release state. When in the weighing state, the weighing system 40 can receive and weigh the slag blocks 310 falling from the buffer mechanism 30. When in the release state, the weighing system 40 can release the weighed slag blocks 310 into the slag hopper 60 for collection, facilitating unified collection and processing of the slag blocks 310 by operators.

[0037] Optionally, in this embodiment, the starting mechanism 20 is mounted on the conveying system 10 and can control the buffer mechanism 30 to switch between a closed state and a large block state, thereby achieving automated operation of the buffer mechanism 30 and thus intelligent weighing. Correspondingly, the starting mechanism 20 can also control the weighing system 40 to switch between a weighing state and a release state, thus cooperating with the state switching of the buffer mechanism 30 to achieve intelligent weighing and automated collection of the intelligent slag weighing device. Furthermore, in this embodiment, a PLC system 50 is also mounted on the tunnel boring machine 100, and the weighing system 40 is communicatively connected to the PLC system 50. The PLC system 50 can receive data transmitted by the weighing system 40 and accumulate and record the data, calculating the overall weight of the slag 300 to achieve automated weighing.

[0038] Combination Figures 1-3As shown, in this embodiment, the conveying system 10 is configured as a belt drive structure, and the screw conveyor 200 can transport the slag 300 onto the belt of the conveying system 10, thereby realizing the transportation of the slag 300 under the rotation of its pulley. Further, the starting mechanism 20 includes a rotating wheel 21, a driven wheel 22, a conveyor belt 23, and a trigger switch 24, and a drive block 201 is provided on the outer side of the conveyor belt 23. Specifically, the rotating wheel 21 is connected to the pulley of the conveying system 10, the driven wheel 22 and the trigger switch 24 are both located on the outer side of the conveying system 10, and the driven wheel 22 is connected to the rotating wheel 21 through the conveyor belt 23. Thus, the rotating wheel 21 rotates synchronously with the pulley under the drive of the pulley, and under the action of the conveyor belt 23, it can drive the driven wheel 22 to rotate synchronously with it, thereby realizing the power drive of the starting mechanism 20. Furthermore, a drive block 201 protrudes from the outer side of the conveyor belt 23, and a trigger switch 24 is fixed to the outer side of the conveying system 10 and communicatively connected to the buffer mechanism 30. Thus, when the drive block 201 moves under the drive of the conveyor belt 23, it can contact the trigger switch 24. When the drive block 201 contacts the trigger switch 24, it can control the state switching of the buffer mechanism 30, thereby changing the buffer mechanism 30 between a closed state and an open state, realizing the receiving and releasing of the slag block 310. Optionally, in this embodiment, the drive block 201 and the trigger switch 24 are arranged in a one-to-one correspondence. When the drive block 201 contacts the trigger switch 24 an odd number of times, the buffer mechanism 30 switches to a closed state; when the drive block 201 contacts the trigger switch 24 an even number of times, the buffer mechanism 30 switches to an open state, thereby realizing the automated operation of the buffer mechanism 30. For example, in this embodiment, when the drive block 201 first contacts the trigger switch 24, the buffer mechanism 30 is in the closed state, which can receive the slag block 310 falling from the conveying system 10. When the drive block 201 contacts the trigger switch 24 for the second time, the buffer mechanism 30 is in the open state, which can release the slag block 310 on the buffer mechanism 30 to the weighing system 40 below for weighing. Repeating the above process can weigh all the slag 300.

[0039] like Figure 2 and Figure 3As shown, in this embodiment, at least two drive blocks 201 and two trigger switches 24 are provided. Each drive block 201 and each trigger switch 24 forms a drive assembly. The two sets of drive assemblies are communicatively connected to the buffer mechanism 30 and the weighing system 40, respectively, so that their switching can be controlled separately. Specifically, in this embodiment, the two trigger switches 24 are respectively located on the upper and lower sides of the conveyor belt 23, and the two drive blocks 201 are spaced apart, with the spacing set as needed. Correspondingly, in addition to the trigger switch 24 communicatively connected to the buffer mechanism 30, another trigger switch 24 is communicatively connected to the weighing system 40. Thus, when the two drive blocks 201 move under the drive of the conveyor belt 23, they can respectively contact the two trigger switches 24, thereby controlling the working state of the buffer mechanism 30 and the weighing system 40 respectively.

[0040] For example, when the trigger switch 24, which is connected to the weighing system 40, is contacted by the corresponding drive block 201, the state switching of the weighing system 40 can be controlled, thereby realizing the change between the weighing state and the release state of the weighing system 40, and realizing the weighing and release of the slag block 310. For example, in this embodiment, when the drive block 201 contacts the trigger switch 24, which is connected to the weighing system 40, an even number of times, the weighing system 40 switches to the weighing state; when the drive block 201 contacts the trigger switch 24, which is connected to the weighing system 40, an odd number of times, the weighing system 40 switches to the release state, thereby realizing the automated operation of the weighing system 40, and can cooperate with the working state of the buffer mechanism 30, so that the slag block 310 can fall stably onto the weighing system 40. For example, in this embodiment, when the drive block 201 first contacts the trigger switch 24 connected to the weighing system 40, the weighing system 40 is in a released state. When the drive block 201 contacts the trigger switch 24 for the second time, the weighing system 40 is in a weighing state, at which point it can receive and weigh the slag blocks 310 falling from the buffer mechanism 30. Upon the next contact with the trigger switch 24, the weighed slag blocks 310 are released into the slag hopper 60 for unified collection. For example, the positions of the two trigger switches 24 and the two drive blocks 201 can be adjusted as needed to adjust the coordination time between the buffer mechanism 30 and the weighing system 40, thereby achieving automated weighing of the slag 300.

[0041] Combination Figure 2 and Figure 4 , Figure 5As shown, in this embodiment, the buffer mechanism 30 includes a first fixed plate 31, a first movable plate 32, and a support member 33, and is provided with a first sealing block 301. Specifically, in this embodiment, there are two first fixed plates 31, and the first movable plate 32 is telescopically disposed between the two first fixed plates 31. The first sealing block 301 is fixed to the side of the first fixed plate 31 facing the first movable plate 32. When the buffer mechanism 30 is in the closed state, the first sealing block 301 can seal the gap between the first fixed plate 31 and the first movable plate 32 to prevent the slag block 310 from falling into the gap and affecting the weighing effect of the weighing system 40 below. Furthermore, the buffer mechanism 30 also includes an electric cylinder, which is fixed to the support member 33. The first movable plate 32 is connected to the output end of the electric cylinder, so that the electric cylinder can drive the telescopic movement of the first movable plate 32 to achieve the switching effect of the working state of the buffer mechanism 30.

[0042] like Figure 1 and Figure 2 As shown, in this embodiment, the weighing system 40 includes a second fixed plate 41, a second movable plate 42, and a second sealing block 401. Correspondingly, the second movable plate 42 is telescopically disposed between the two second fixed plates 41, and the second sealing block 401 is fixed to the side of the second fixed plate 41 facing the second movable plate 42. When the weighing system 40 is in the weighing state, the second sealing block 401 can seal the gap between the second fixed plate 41 and the second movable plate 42, thereby ensuring the accuracy of the weighing of the slag block 310 by the weighing system 40 and preventing the slag block 310 from falling into the slag hopper 60 at the gap, affecting the measurement results. Exemplarily, the telescopic movement of the second movable plate 42 in this embodiment is also driven by an electric cylinder, which will not be described in detail here. Furthermore, in this embodiment, a weighing sensor is provided on the second movable plate 42 to measure the weight of each falling slag block 310. The weighing sensor is communicatively connected to the PLC system 50, thereby enabling the measurement and data transmission of the slag block 310's weight. This allows the PLC system 50 to collect the weight data of each slag block 310 and calculate the total weight of the slag 300 after accumulation. Exemplarily, in this embodiment, both the first sealing block 301 and the second sealing block 401 are made of rubber to ensure their sealing effect.

[0043] Working process: During the tunneling process, the excavated soil 300 generated by the tunnel boring machine 100 is transported from the inside of the tunnel boring machine 100 to the outside via the screw conveyor 200, until it is transported to the conveying system 10. The pulley of the conveying system 10 rotates continuously, conveying the excavated soil blocks 310 above the first movable plate 32. Then the pulley continues to drive the rotating wheel 21 to rotate, and the conveyor belt 23 rotates synchronously with it. After rotating a certain number of times, the drive block 201 will contact the trigger switch 24, so that the electric cylinder of the buffer mechanism 30 can receive the signal, causing the first movable plate 32 to open, thereby releasing the excavated soil blocks 310 onto the second movable plate 42. The weighing sensor in the second movable plate 42 monitors the excavated soil. The soil block 310 is weighed and the data is transmitted to the PLC system 50. Then, when the drive block 201 contacts the trigger switch 24 for the second time, the electric cylinder of the buffer mechanism 30 receives a signal again, causing the first movable plate 32 to close, sealing the drop opening of the soil block 310, facilitating the next weighing. Correspondingly, the second movable plate 42 opens and closes according to the signal of another trigger switch 24, so as to release the measured soil block 310 into the slag hopper 60 for centralized processing. Finally, the PLC system 50 automatically records and accumulates the results of each weighing and forms the total weight data, so that the operators can view and manage the total weight of the soil block 300 in real time using the PLC system 50.

[0044] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
