Description

TECHNICAL FIELD

[0001] The present application mainly relates to the technical field of road construction, in particular to a ramming and finishing device for road construction. BACKGROUND

[0002] In the initial stage of road construction, the road surface must be fully rammed to ensure that the road surface base is solid and stable. Only when the road surface base is completely solid and stable can subsequent material laying work be carried out smoothly. Therefore, ramming the road surface is an important link that cannot be ignored in road construction.

[0003] A ground ramming device for road construction described in the prior art comprises a bottom plate and a box body, the box body is fixedly connected to the bottom plate, the box body is hollow and circular inside, a ramming assembly is arranged in the box body, a roller is rotatably arranged on the bottom plate, a power assembly is arranged on the roller, the power assembly drives the roller to rotate, and a supporting assembly is arranged on the bottom plate.

[0004] The above technology can effectively ram the ground and improve the actual use effect of the device, and has good application prospects. However, the dust problem generated during the ramming operation has not been effectively solved. The large amount of dust discharged after suction not only harms the health of construction personnel, but also pollutes the surrounding environment. At the same time, the problem of insufficient compaction degree caused by soil pores cannot be detected and solved specifically, and manual post-detection and separate reinforcement construction are required, resulting in the fragmentation of the dust removal, reinforcement and ramming processes. SUMMARY

Both the outer walls of the shaft rod and the rotating shaft are fixedly fitted with transmission wheels. The two transmission wheels are connected by a transmission chain. A worm gear is fixed to the outer wall of the shaft rod near the fixed plate. A fixed plate is installed on the top of the storage box with screws.

The striking block passes through the top wall of the storage box, and the bottom of the striking block matches the upper surface of the filter screen. Fixed seats are symmetrically sleeved on the upper part of the transmission shaft, and the bottom ends of the two fixed seats are fixed to the top wall of the storage box with screws.

[0011] Specifically, the dust collection structure includes an annular tube installed inside a square box. Multiple holes are evenly distributed on the lower surface of the annular tube. The top of the air intake is connected to the multiple holes via a suction channel. Mounting slots are provided on both sides of one side of the square box located within the storage box.

When driving the tamping components, no additional power source is required, reducing energy consumption. Furthermore, dust collection and hydrogel preparation rely on the collaboration of sensors and components, reducing manual operation steps. The entire equipment achieves efficient compaction while also taking into account environmental protection and soil improvement functions, significantly improving the overall benefits of road construction. The equipment has a compact and reasonable structural design, and the linkage between various components is smooth, which not only ensures the stability and reliability of compaction operations, but also simplifies the operation complexity through automated processing, effectively reducing construction costs and time consumption.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0019] The embodiments of the present invention will now be described.

[0020] It should be noted that the square box 1 and the storage box 5 are mounted on a base plate with casters. The base plate has matching holes at the storage slot 101, and all electrical components of the equipment are controlled by an external controller.

[0021] In this embodiment, please refer to Figures 1-8As shown, a road construction compaction and finishing device includes a square box 1, a cylindrical box 2, a storage box 5 for dust collection, and a preparation component 6. The bottom of the cylindrical box 2 is integrally connected to the top of the square box 1. The storage box 5 is located on one side of the square box 1. A drive chamber 201 is opened inside the cylindrical box 2. A circular storage groove 101 is opened at the bottom of the square box 1. A compaction block 101 is placed in the storage groove 101. A compaction sensor 1012 is embedded in the center of the bottom of the compaction block 1011. The probe of the compaction sensor 1012 is made of wear-resistant ceramic material. A compaction component 3 is placed in the drive chamber 201. The execution end of the compaction component 3 is inserted into the storage groove 101 and connected to the top of the compaction block 1011. An air intake 102 is opened at the opening of the storage groove 101. The air intake 102 is connected to the storage box 5 through a dust collection structure. A filter screen 501 is installed in the storage box 5. The dust collection structure includes an annular tube 103 installed inside a square box 1. Multiple holes are evenly distributed on the lower surface of the annular tube 103. The top of the air intake 102 is connected to the multiple holes through a suction channel 1021. The square box 1 has mounting slots 105 on both sides of one side of the storage box 5. A suction pump 106 is installed in each of the two mounting slots 105. The input and output ports of the two suction pumps 106 are respectively connected to a dust collection pipe 104 and a collection pipe 1061. The dust collection pipe 104 is connected to the upper surface of the annular tube 103. The collection pipe 1061 is inserted into the storage box 5 and its end passes through a filter screen 501. A striking component 4 is installed on the top of the storage box 5. The striking component 4 is connected to the drive source of the compaction component 3. Following the movement of the compaction block 1011, the dust attached to the filter screen 501 is shaken off. The top of the storage box 5 is also symmetrically provided with exhaust screens for the exhaust of clean air. A material level sensor 502 is installed in the middle of the inner wall of the storage box 5. The preparation component 6 is located in the storage box 5. The preparation component 6 prepares the collected dust into hydrogel according to the signal of the material level sensor 502 and injects it into the soil pores to improve the compaction.

[0022] When ground compaction is required for road construction, the equipment is moved to the work area, and the whole machine is started through the external controller. The compaction component 3 in the drive chamber 201 starts to work, driving the compaction block 1011 in the collection tank 101 to vibrate at high frequency to compact the ground. At the same time, the dust collection structure is activated. The suction pump 106 forms a negative pressure in the annular pipe 103 through the dust collection pipe 104. The air intake 102 at the opening of the collection tank 101 draws the dust generated by compaction into the annular pipe 103 through the suction channel 1021, and then transports it to the storage box 5 through the collection pipe 1061. The dust is filtered by the filter screen 501 in the storage box 5 and remains in the box. Clean air passes through the filter screen 501 and is discharged from the exhaust screen. During this process, the striking component 4, driven by the compaction component 3, intermittently strikes the filter screen 501 to shake off the dust attached to the filter screen 501, ensuring the continuous and effective operation of the filter screen 501.

[0023] As dust accumulates, when the level sensor 502 detects that the amount of dust has reached the set value, it sends a signal to the external controller. The external controller receives the signal and starts the preparation component 6. According to the received signal, the preparation component 6 mixes the collected dust with water and bio-based gelling agent to prepare hydrogel. When the compaction sensor 1012 at the bottom of the compacted block 1011 detects the soil pore area (compaction degree is not up to standard), the worker can use the grouting pipe 605 to inject the hydrogel into the soil pores to improve the compaction degree of the ground. This solves both dust pollution and targeted soil reinforcement, improving soil compaction and avoiding the efficiency loss caused by the disconnect between dust removal, reinforcement, and compaction in traditional construction. Furthermore, no additional power source is needed when driving the hammering component 4, reducing energy consumption. Dust collection and hydrogel preparation rely on the collaboration of sensors and components, reducing manual operation. The entire device achieves efficient compaction while also taking into account environmental protection and soil improvement functions, significantly improving the overall benefits of road construction.

[0024] Please see Figures 3-7 As shown, the compaction component 3 includes a top plate 301, which is fixedly connected to the top of the drive cavity 201 by bolts. Guide rods 3011 are symmetrically fixed to the lower surface of the top plate 301. A stepper motor 302 is bolted to the lower surface of the top plate 301 between the two guide rods 3011. A movable plate 304 and a lifting plate 305 are sequentially arranged below the top plate 301. Both the movable plate 304 and the lifting plate 305 are slidably fitted onto the two guide rods 3011. The output shaft of the stepper motor 302 is connected to the movable plate 304 via a first connecting rod 303. Sliding rods 3041 are symmetrically fixed to the lower surface of the movable plate 304, and the bottom ends of both sliding rods 3041 penetrate the lifting plate 305. A connecting rod 3051 is welded to the bottom end of the lifting plate 305. The bottom end of the connecting rod 3051 is inserted into the storage groove 101 and welded to the tamping block 1011. The top end of the first connecting rod 303 is fixedly sleeved on the outer wall of the output shaft of the stepper motor 302. The bottom end of the first connecting rod 303 is movably connected to the movable plate 304. The outer wall of the two guide rods 3011 between the movable plate 304 and the lifting plate 305 is sleeved with a first shock-absorbing spring 3012. The bottom ends of the two slide rods 3041 are welded with limit plates. The outer wall of the two slide rods 3041 between the lifting plate 305 and the limit plates is sleeved with a second shock-absorbing spring 3042. The top of the outer wall of the cylindrical box 2 is provided with a heat dissipation hole 202. The striking assembly 4 includes a rotating shaft 401 and a shaft 402. One end of the rotating shaft 401 is fixedly connected to the output shaft end face of the stepper motor 302 via a coupling. The other end of the rotating shaft 401 extends out of the cylindrical housing 2 to the outside. One end of the shaft 402 is rotatably connected to the bottom of the outer wall of the cylindrical housing 2. Both the outer walls of the shaft 402 and the rotating shaft 401 are fixedly fitted with transmission wheels 403. The two transmission wheels 403 are connected by a transmission chain 4031. A worm gear 4021 is fixed to the outer wall of the shaft 402 near the fixed plate 404. The top of the storage box 5 is fitted with a fixed plate 404 by screws. The worm gear 4021 is rotatably connected to the fixed plate 404. A worm wheel 405 is meshed with the lower tooth surface of the worm gear 4021. A transmission shaft 4051 is fixedly inserted through the center of the worm wheel 405. Both ends of the transmission shaft 4051 are connected to striking blocks 408 via a second connecting rod 407. A support seat 4011 is fitted on the rotating shaft 401. The support seat 4011 is fixed to the lower surface of the top plate 301 with screws. The top of the second connecting rod 407 is fixedly fitted on the outer wall of the transmission shaft 4051. The bottom of the second connecting rod 407 is hinged to the top of the striking block 408 by a pin. The striking block 408 passes through the top wall of the storage box 5. The bottom of the striking block 408 matches the upper surface of the filter screen 501. Fixed seats 406 are symmetrically fitted on the upper part of the transmission shaft 4051. The bottom ends of the two fixed seats 406 are fixed to the top wall of the storage box 5 with screws.

[0025] When the stepper motor 302 starts to run, its output shaft drives the movable plate 304 to move up and down on the guide rod 3011 through the first connecting rod 303. Since the movable plate 304 and the lifting plate 305 are connected by the sliding rod 3041, and the sliding rod 3041 is fitted with a second shock-absorbing spring 3042, and the guide rod 3011 is fitted with a first shock-absorbing spring 3012 between the movable plate 304 and the lifting plate 305, when the movable plate 304 moves up and down, it will drive the lifting plate 305, the connecting rod 3051 connected to the bottom of the lifting plate 305, and the compaction block 1011 to make impact movements, thereby realizing the compaction of the ground. During this process, the first shock-absorbing spring 3012 on the guide rod 3011 and the second shock-absorbing spring 3042 on the sliding rod 3041 extend and retract synchronously to buffer the impact load of the movable plate 304 and the lifting plate 305. The heat dissipation holes 202 on the outer wall of the cylindrical box 2 are used to dissipate heat from the stepper motor 302. Meanwhile, the output shaft of the stepper motor 302 also drives the rotating shaft 401 to rotate through the coupling. The rotating shaft 401 drives the shaft 402 to rotate through the transmission wheel 403 and the transmission chain 4031. The worm gear 4021 on the shaft 402 drives the worm wheel 405 to rotate. The worm wheel 405 drives the transmission shaft 4051 to rotate. The transmission shaft 4051 drives the striking block 408 to move up and down through the second connecting rod 407. The striking block 408 moves vertically through the hole penetrating the storage box 5. The striking block 408 continuously strikes the filter screen 501 on the top wall of the storage box 5, shaking off the dust attached to the filter screen 501, avoiding clogging of the filter screen 501, and ensuring the normal operation of the dust collection structure.

[0026] Please see Figure 1 , Figure 3 , Figure 4 and Figure 8 As shown, the preparation component 6 includes a water tank 606, a storage tank 607, a stirring rod 601, and two slurry pumps 603. The water tank 606 and the storage tank 607 are symmetrically installed on the top two sides of the square box 1. The water tank 606 is filled with clean water, and the storage tank 607 is filled with a bio-based gelling agent. Metering pumps 608 are installed in both the water tank 606 and the storage tank 607. The output ports of the two metering pumps 608 are connected to feed pipes 6081. The ports of the two feed pipes 6081 are inserted into the storage tank 5 and pass through the filter screen 501. The stirring rod 601... 01 is horizontally set at the bottom of the storage tank 5 and rotatably connected to the inner wall. The side wall of the storage tank 5 is equipped with a drive motor 602 by screws. The output shaft of the drive motor 602 is connected to the stirring rod 601 by a coupling. Two slurry pumps 603 are symmetrically installed on the bottom wall of the storage tank 5. The output ports of the two slurry pumps 603 are connected to hoses 604. The two hoses 604 are located on the outside of both sides of the storage tank 5 and their ports are connected to grouting pipes 605. The outer walls of both sides of the storage tank 5 are equipped with clamps for placing the grouting pipes 605 by screws.

[0027] As the compaction operation continues, the amount of dust in storage tank 5 gradually increases. When the level sensor 502 detects that the amount of dust has reached the set value, it sends a signal to the external controller, which then starts the preparation component 6. First, it controls the metering pump 608 in water tank 606 and storage tank 607 to operate, injecting clean water and bio-based gelling agent into the bottom of storage tank 5 through the feed pipe 6081. Then, it starts the drive motor 602 on the side wall of storage tank 5. The drive motor 602 drives the stirring rod 601 to rotate, mixing the dust, clean water and gelling agent to form a hydrogel. The prepared hydrogel is in storage tank 5. When the compaction sensor 1012 at the bottom of the compacted block 1011 detects the soil pore area, the worker can hold the grouting pipe 605 to inject the hydrogel into the soil pores to improve the compaction of the ground.

[0028] The working principle of this invention is as follows: When ground compaction is required for road construction, the equipment is moved to the work area, and the entire machine is started via an external controller. The compaction component 3 in the drive chamber 201 begins to work, and the stepper motor 302 starts to run. Its output shaft drives the movable plate 304 to reciprocate up and down on the guide rod 3011 via the first connecting rod 303. Since the movable plate 304 and the lifting plate 305 are connected by a sliding rod 3041, and a second shock-absorbing spring 3042 is sleeved on the sliding rod 3041, the guide rod 3011 is located between the movable plate 304 and the lifting plate 305. A first damping spring 3012 is sleeved between them. When the movable plate 304 moves up and down, it will drive the lifting plate 305 and the connecting rod 3051 connected to the bottom of the lifting plate 305 and the compaction block 1011 to make impact movements, so as to realize the compaction of the ground. During this process, the first damping spring 3012 on the guide rod 3011 and the second damping spring 3042 on the slide rod 3041 extend and retract synchronously to buffer the impact load of the movable plate 304 and the lifting plate 305. The heat dissipation hole 202 on the outer wall of the cylindrical box 2 is for the stepper motor 302 to dissipate heat. At the same time, the dust collection structure is activated. The suction pump 106 forms a negative pressure in the annular pipe 103 through the dust collection pipe 104. The air inlet 102 at the opening of the collection slot 101 draws the dust generated by compaction into the annular pipe 103 through the suction channel 1021, and then transports it to the storage box 5 through the collection pipe 1061. The dust is filtered by the filter screen 501 in the storage box 5 and remains in the box. Clean air passes through the filter screen 501 and is discharged from the exhaust screen. While the stepper motor 302 is running, its output shaft also drives the rotating shaft 401 to rotate through the coupling. The rotating shaft 401 drives the shaft 402 to rotate through the transmission wheel 403 and the transmission chain 4031. The worm gear 4021 on the shaft 402 drives the worm wheel 405 to rotate. The worm wheel 405 drives the transmission shaft 4051 to rotate. The transmission shaft 4051 drives the striking block 408 to move up and down through the second connecting rod 407. The striking block 408 moves vertically through the hole penetrating the storage box 5. The striking block 408 continuously strikes the filter screen 501 on the top wall of the storage box 5, shaking off the dust attached to the filter screen 501, preventing the filter screen 501 from clogging, and ensuring the normal operation of the dust collection structure. As the compaction operation continues, the amount of dust in storage tank 5 gradually increases. When the level sensor 502 detects that the amount of dust has reached the set value, it sends a signal to the external controller, which then starts the preparation component 6. First, it controls the metering pump 608 in water tank 606 and storage tank 607 to operate, injecting clean water and bio-based gelling agent into the bottom of storage tank 5 through the feed pipe 6081. Then, it starts the drive motor 602 on the side wall of storage tank 5. The drive motor 602 drives the stirring rod 601 to rotate, mixing the dust, clean water and gelling agent to form a hydrogel. The prepared hydrogel is in storage tank 5. When the compaction sensor 1012 at the bottom of the compacted block 1011 detects the soil pore area, the worker can hold the grouting pipe 605 to inject the hydrogel into the soil pores to improve the compaction of the ground.
