[0002] During the excavation of hard rock tunnels, trenches need to be excavated at the bottom of the tunnel to meet drainage needs. The common methods for excavating trenches in hard rock tunnels are blasting and mechanical excavation. The blasting method is prone to more over-excavation and under-excavation, requiring secondary shaping and repair, which increases construction costs; the mechanical excavation method generally uses a milling machine to excavate the trench, but due to the small cross-section of the trench, it is difficult to clean the slag in the trench.

[0003] In order to solve the problem of high difficulty in cleaning slag by mechanical excavation, the Chinese invention patent application with application publication number CN115198823A and application publication date October 18, 2022 discloses a chain trencher, which includes a walking main body, and the walking main body is connected to an excavation device through a connecting arm, and the excavation device includes a frame, and the top of the frame is rotatably equipped with a driving sprocket, and the bottom of the frame is rotatably equipped with a driven sprocket, and a chain is wrapped around the driving sprocket and the driven sprocket, and the chain is provided with a roller for crushing rocks and a bucket for transporting slag upward, and the walking main body or the frame is provided with a slag discharge device for receiving the slag in the bucket at the top of the frame.

[0004] The above technical solution utilizes the roller cutters on the chain to break rocks, and needs to utilize the roller cutters to exert a large pressure on the rock mass to fracture the rock mass. However, since the roller cutters are mounted on the chain, and the chain needs to rotate around the driving sprocket and the driven sprocket, it is difficult to provide a sufficiently large pressure, and the efficiency of construction in hard rock geology is low.

[0025] The present invention is further described in detail below in conjunction with the embodiments.

[0026] The utility model utilizes a trench excavation mechanism to excavate a trench, and utilizes a chain-type slag discharge mechanism to simultaneously clean up slag and stone in the trench, which can ensure convenient slag discharge and improve excavation efficiency.

[0027] The specific embodiment of the hard rock geological trench excavation and slag removal integrated machine provided by the utility model is as follows:

[0028] A hard rock geological trench excavation and slag removal integrated machine, see attached Figure 1 , including a main body 1, a walking mechanism, a trench excavation mechanism, a chain-type slag discharge mechanism and a slag transfer mechanism. The main body 1 is also equipped with a complete machine hydraulic power source, an electrical control system, a sensor system, a communication system and a manual control console.

[0029] The walking mechanism includes tracks 2 located on both sides of the bottom of the main body 1. The distance between the two tracks 2 is greater than the width of the groove. During construction, the main body 1 spans over the groove, and the two tracks 2 are respectively located on both sides of the groove. The space between the two tracks 2 also constitutes a storage space.

[0030] See attached Figure 2 A telescopic arm 3 is provided at the front side of the main body 1, a connecting arm 4 is hingedly provided at the front end of the telescopic arm 3, and a pitch adjustment cylinder 5 for adjusting the pitch angle of the connecting arm 4 is hingedly provided between the telescopic arm 3 and the connecting arm 4. The trench excavation mechanism is provided on the connecting arm 4, and the trench excavation mechanism can adopt the swing-type hard rock cutting device 6 in the Chinese utility model patent application with application publication number CN114991795A to obtain higher excavation efficiency. In other embodiments, the trench excavation mechanism can also adopt the milling head of the milling machine.

[0031] See attached Figure 3 and attached Figure 4 The chain-type slag discharge mechanism includes a support frame 7, and a driving sprocket 8 and a driven sprocket 9 are rotatably arranged at both ends of the support frame 7. A chain 10 is arranged between the driving sprocket 8 and the driven sprocket 9 for transmission. A hopper 11 for slag discharge and a shaping tooth 12 for shaping the bottom of the groove are arranged on the chain 10. A slag discharge driving device for driving the driving sprocket 8 to rotate is arranged on the support frame 7. The slag discharge driving device is a slag discharge driving motor 13, which is specifically a hydraulic motor, and can also be an electric motor in other embodiments.

[0032] The support frame 7 is rotatably matched with the main body 1. The main body 1 is provided with an adjusting driving device for adjusting the pitch angle of the support frame 7. The adjusting driving device is specifically an adjusting driving motor 14. The adjusting driving motor 14 is specifically a hydraulic motor. In other embodiments, it can also be an electric motor. The adjusting driving device can also be an adjusting driving oil cylinder. One end of the adjusting driving oil cylinder is hinged to the main body 1, and the other end is hinged to the support frame 7. The pitch angle of the support frame 7 is controlled by adjusting the extension and contraction of the driving oil cylinder. The pitch angle of the support frame 7 can be adjusted by the adjusting driving device, so that the support frame has a slag discharge position and a storage position. During construction, the support frame 7 is extended into the groove to reach the slag discharge position. When the support frame 7 is at the slag discharge position, the driven sprocket 9 is located obliquely below the driving sprocket 8. When the site needs to be transferred, the support frame 7 is lifted to the storage position so that the support frame 7 is stored in the storage space.

[0033] The shaping teeth 12 are specifically pick-shaped cutting teeth. In other embodiments, the shaping teeth 12 can also be hobs. The shaping teeth 12 are arranged in groups, each group has two rows of shaping teeth 12, and each row has one or two shaping teeth 12. The shaping tooth groups and the hoppers 11 are arranged alternately, and the three adjacent groups of shaping teeth 12 are arranged in a "V" shape together. Each group of shaping teeth 12 is arranged in a "V" shape or a trapezoidal shape. On the one hand, each row of shaping teeth 12 in the three connected groups of shaping teeth 12 can be staggered to ensure that there is enough shaping range for the bottom wall of the groove. On the other hand, the shaping teeth 12 can have a gathering and guiding effect on the slag, so that the slag can smoothly enter the corresponding hopper 11.

[0034] In other embodiments, the shaping teeth 12 may not be arranged in the above manner, but the shaping teeth 12 may be arranged in a wave shape along the length direction of the chain 10, so that each row of shaping teeth 12 is staggered along the length direction of the chain 10. The shaping teeth 12 may not be arranged in groups, but each shaping tooth 12 may be arranged independently, for example, each shaping tooth 12 is arranged alternately with the hopper 11.

[0035] See attached Figure 5 The slag transfer mechanism includes a slag chute 17 and a foldable transfer belt conveyor. The slag chute 17 is composed of two baffles of the main body 1 and is used to guide the slag to prevent the slag from scattering to areas outside the transfer belt conveyor.

[0036] The transfer belt conveyor includes a central transfer belt conveyor 18, a left transfer belt conveyor 15 and a right transfer belt conveyor 19. The central transfer belt conveyor 18 is located downstream of the chain slag discharge mechanism and is used to receive the slag on the chain slag discharge mechanism. At the same time, the central transfer belt conveyor 18 can rotate forward or reverse to transfer the slag to the left or right side of the hard rock geological trench excavation slag discharge integrated machine. The left transfer belt conveyor 15 and the right transfer belt conveyor 19 are respectively located on the left and right sides of the hard rock geological trench excavation slag discharge integrated machine, and are both located downstream of the central transfer belt conveyor 18. The left transfer belt conveyor 15 and the right rotating belt conveyor 19 are both foldable, and have a horizontal working position and a vertical storage position after folding. When the left transfer belt conveyor 15 and the right rotating belt conveyor 19 are both located in the storage position, the width of the hard rock geological trench excavation slag discharge integrated machine can be reduced, which is convenient for moving the entire machine. When slag is discharged, one of the left transfer belt conveyor 15 and the right rotating belt conveyor 19 is in the working position to receive the slag and stone transferred by the central transfer belt conveyor 18 and finally transfer the slag and stone to the transport vehicle or the transport belt.

[0037] In other embodiments, the slag transfer mechanism may also include only a central transfer belt conveyor 18. After the central transfer belt conveyor 18 is used to transport the slag to one side of the hard rock geological trench excavation and slag removal integrated machine, the slag is transferred to the transport vehicle using the belt conveyor on the transport vehicle.

[0038] Two supporting legs 16 are provided at the rear of the main body 1. The supporting legs 16 include a hydraulic cylinder and a support shoe fixedly arranged at the end of the hydraulic cylinder piston rod. When the trench excavation mechanism is cutting and excavating, the supporting legs 16 support the ground to ensure the stability of the whole machine.

[0039] When in use, the hard rock geological trench excavation and slag removal integrated machine is driven into the tunnel, and then the trench excavation mechanism is lowered, and the trench excavation mechanism is used to perform the initial shaping of the tunnel. After the initial shaping of the tunnel, more slag will be produced. After that, the support frame 7 is adjusted from the storage position to the slag discharge position, and the groove is reshaped for the second time using the shaping teeth 12. At the same time, the hopper 11 is used to clean the slag in the groove and transfer the slag out of the groove. Finally, the slag is transferred to the transport vehicle or the transport belt by the slag transfer mechanism. After the trench construction is completed, the trench excavation mechanism is lifted, and the support frame 7 is rotated to the storage position to facilitate the transfer of the hard rock geological trench excavation and slag removal integrated machine.

[0040] By separating the initial trench excavation from the slag discharge, a trench excavation mechanism with high excavation efficiency can be used under the premise of convenient slag discharge, thereby improving the overall construction efficiency of trench excavation. And while the slag is discharged, the bottom wall of the trench is trimmed by the trimming teeth 12 to make the bottom wall of the trench smoother, reducing the workload in the later stage. In addition, the smoother bottom wall of the trench can also facilitate the hopper 11 to shovel up the slag and avoid the hopper 11 being blocked by the protruding rocks, which is conducive to improving the cleaning effect of the slag.

[0041] In other embodiments, the chain may not be provided with shaping teeth, and only the hopper on the chain may be used for slag cleaning.

[0042] In other embodiments, the support frame can be rotated to a vertical downward position, and this position is used as the slag discharge position of the support frame. At this time, the driven sprocket is located directly below the driving sprocket.

[0043] In other embodiments, the walking mechanism is a tire. In this embodiment, the bottom of the main body is close to the ground. In order to better accommodate the support frame, a receiving groove for accommodating the support frame is provided at the bottom of the main body. When the support frame needs to be accommodated, the support frame can be rotated to enter the receiving groove.

[0044] In other embodiments, the support frame does not need to be adjusted in pitch. In this embodiment, the support frame is fixedly mounted on the bottom of the main body by bolts and only has a slag discharge position. After the trench construction is completed, the support frame can be directly removed from the bottom of the main body and stored on the main body.

[0045] Finally, it should be noted that the above is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments without creative work, or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
