Description
Technical Field
[0001] This utility model relates to the field of tunnel spoil classification and recycling technology, and in particular to a tunnel spoil classification, recycling and reuse treatment device. Background Technology
[0002] Tunnel excavated soil is waste generated during tunnel construction, containing sand, clay, stones, etc., and may be mixed with impurities such as bentonite and metals. It is characterized by high moisture content and complex particle size distribution, and needs to be treated to achieve resource utilization or environmentally friendly disposal. Tunnel excavated soil grading and recycling treatment equipment is used to classify and process construction excavated soil according to particle size. Through screening, crushing, washing, and dewatering, mud, sand, and stone particles are separated to achieve the classification, recycling, and resource utilization of materials of different particle sizes, thereby improving the comprehensive utilization rate of excavated soil.
[0003] When the screening device in the tunnel excavation soil grading and recycling treatment unit is working, the excavation soil is fed into the screen surface by the feeding conveyor system or excavator. The screen surface is driven by a motor to vibrate, causing the excavation soil to jump on the screen surface. Due to the difference in particle size, particles smaller than the screen holes pass through the screen and fall down, while particles larger than the screen holes continue to move on the screen surface and are discharged at the end of the screen surface. This achieves the grading of the excavation soil according to particle size, providing materials of different particle sizes for subsequent crushing, reuse and other processes.
[0004] In existing technologies, some tunnel excavation waste grading and recycling systems use screening devices that handle slurry-like excavation waste. The high viscosity of the slurry causes it to clump together with the stones, making separation difficult. Furthermore, the slurry easily clogs the screens, leading to a significant decrease in screening efficiency. Fine excavation particles cannot pass through the screens in time, resulting in reduced throughput. Simultaneously, slurry clogging reduces the effective area of the screen openings, further exacerbating screening difficulties. It can also increase the load on the screen surface, causing motor overload and affecting normal equipment operation. Moreover, clumping can accelerate screen wear, shorten the lifespan of the screening device, and increase maintenance costs. Therefore, a tunnel excavation waste grading and recycling system is proposed to address these problems. Utility Model Content

The support 1 is the supporting structure of the entire device and plays a load-bearing role. Multiple fixing blocks 2 are fixedly connected to the rear top of the support 1. Fixing columns 3 are fixedly connected to the adjacent sides of two fixing blocks 2. The fixing blocks 2 and fixing columns 3 enable the bottom end of the telescopic bar 4 to rotate, similar to a hydraulic cylinder in a truck tipper. The telescopic bar 4 is rotatably connected to the outside of the fixing column 3. The activation of the telescopic bar 4 drives the mixing bucket 6 to rotate around the fixed shaft 11. The other end of the telescopic bar 4 is rotatably connected to a rotating column 5. The rotating column 5 enables the other end of the telescopic bar 4 to also rotate, facilitating the telescopic bar 4 to provide force in different directions.
[0013] A mixing bucket 6 is fixedly connected to the top rear side of the support frame 1. A motor 7 is fixedly connected to the bottom of the mixing bucket 6. Multiple stirring rods 8 are fixedly connected to the drive end of the motor 7. The starting of the motor 7 causes the stirring rods 8 to rotate, preventing the mud-like slag inside the mixing bucket 6 from forming lumps and colloids. Multiple rotating blocks 9 are fixedly connected to the front side of the mixing bucket 6. The rotating blocks 9 are rotatably connected to the fixed shaft 11, which facilitates the pouring of material from the mixing bucket 6. A water pipe 14 is fixedly connected to the top rear side of the support frame 1. The water pipe 14 is a flexible structure. The water pipe 14 sprays water into the mixing bucket 6 to dilute the mud-like slag. A screen bucket 10 is fixedly connected to the top of the support frame 1. The screen bucket 10 is the screening part of the entire device, providing space for screening. A fixed shaft 11 is fixedly connected to the interior rear side of the screen bucket 10. The fixed shaft 11 is used to connect the rotating blocks 9, which facilitates the pouring of material from the mixing bucket 6. A disassembly assembly is threaded inside the screen bucket 10. The disassembly assembly can quickly disassemble the screen 15, shortening the replacement time of the screen 15.
[0014] The bottom end of the mixing bucket 6 is connected to the rear top of the support 1, which provides support for the mixing bucket 6. The two rotating columns 5 are fixedly connected to the left and right sides of the mixing bucket 6 on their adjacent sides. The rotating columns 5 provide the mixing bucket 6 with a force point, which facilitates the lifting of the mixing bucket 6 by the telescopic bar 4. The outside of the water pipe 14 is fixedly connected to the inside of the mixing bucket 6. The water pipe 14 injects water into the mixing bucket 6 to dilute the mud-like slag. The inside of the multiple rotating blocks 9 is rotatably connected to the outside of the fixed shaft 11. The top of the support 1 is fixedly connected to two water pipes 12. The outside of the two water pipes 12 is fixedly connected to multiple spray guns 13. The water pipes 12 work with the spray guns 13 to wash away the mud and sand remaining on the screen 15 to prevent clogging of the screen 15.
[0015] Reference Figures 3 to 5The disassembly assembly includes multiple bolts 16, all of which are threaded to the inside of the screen hopper 10. The bolts 16 provide a rotational force point while locking the gear 18. Fastening plates 17 are fixedly connected to the outside of the multiple bolts 16, which lock the bolts 16 and increase the torque. Gears 18 are fixedly connected to the outside of the multiple bolts 16, and a rack 19 is meshed with the outside of the gear 18. A trapezoidal pressure block 20 is fixedly connected to the bottom end of the rack 19. The movement of the gear 18 drives the rack 19 to slide forward, and the movement of the rack 19 drives the trapezoidal pressure block 20 to slide forward.
[0016] The outer side of the fastening plate 17 contacts the outer side of the sieve hopper 10, locking the bolt 16. The outer side of the trapezoidal pressure block 20 is slidably connected to the inside of the sieve hopper 10. A slider 21 is fixedly connected to the outer side of the trapezoidal pressure block 20. The slider 21 has a certain inclination and is slidably connected to the inside of the sieve hopper 10. The bottom end of the trapezoidal pressure block 20 contacts the top end of the screen 15. A motor 22 is fixedly connected to the top end of the bracket 1. The motor 22 provides vibration, causing the screen 15 to vibrate.
[0017] Working principle: The excavator pours the mud-like tunnel excavation into the mixing bucket 6. At this time, the motor 7 starts and the water pipe 14 injects an appropriate amount of water. The start of the motor 7 drives the mixing rod 8 to rotate. The rotation of the mixing rod 8 makes the mud-like tunnel excavation and water fully mixed to prevent the mud-like excavation from forming colloids and lumps. At this time, the telescopic rod 4 starts and drives the mixing bucket 6 to rotate along the fixed shaft 11 (the motor 7 also rotates). The tunnel excavation is poured into the screen bucket 10. At this time, the spray gun 13 sprays water to wash away the mud and sand in conjunction with the diluted mud, leaving the stones on the screen 15 to prevent the mud and sand from clogging the screen 15, thus achieving the anti-clogging of the screen 15.
[0018] Loosen bolt 16 with a pry bar, causing fastening plate 17 to disengage from screen hopper 10. Loosening bolt 16 causes gear 18 to rotate. The movement of gear 18 causes rack 19 to slide forward. The movement of rack 19 causes trapezoidal pressure block 20 to slide forward. Since slider 21 is set with a certain degree of inclination ( Figure 5 As shown, when the trapezoidal pressure block 20 slides forward, its bottom end can be disengaged from the screen 15, thereby loosening the screen 15; at this time, the screen 15 can be removed to complete the disassembly and replacement of the screen 15.
[0019] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
