At the same time, the reciprocatingly swinging dispersion plate can buffer and absorb the falling landfill soil, avoiding the soil impacting the pipeline and causing damage to the pipeline, thereby improving the safety of construction.

[0031] 3. In the present invention, by setting a compaction component, the hollow scraper rod scrapes and flattens the landfill material that has been filled in the groove, and the auxiliary motor drives the eccentric hammer to rotate through the connecting shaft, the connecting ring and the connecting rod, and makes the hollow scraper rod vibrate at a high frequency. While scraping and flattening the landfill material, it can also vibrate and compact the landfill material. On the one hand, the landfill material can be leveled and the flatness of the road surface can be improved. On the other hand, through vibration compaction, the compaction between the landfill materials can be improved, the gaps between the landfill materials can be reduced, and the landfill effect can be improved.

[0048] The specific implementation method is as follows: by setting a layered landfill component 4, the driving wheel 411 drives the pipe winding wheel 3 to rotate through the first transmission belt 404 and the driven wheel 405, so as to realize the orderly discharge of the pipe, and cooperate with the laying traction wheel 10 to realize the automated orderly laying of the pipe, thereby improving the construction efficiency.

The soil with larger particles laid on the upper layer can further increase the bearing capacity of the roadbed, making the entire pipeline system more stable.

The tops of the multiple bidirectional racks 904 are connected to the same screw seat 901, and the screw seat 901 is slidably connected to the first discharge pipe 5 or the second discharge pipe On one side of the second feeding pipe 11, a reciprocating screw 903 is connected to the internal thread of the screw seat 901. The reciprocating screw 903 and the reciprocating screw 903 are both rotatably connected with mounting parts at both ends. The mounting parts are connected to one side of the first feeding pipe 5 or the second feeding pipe 11. A fixed motor 906 is provided on one side of the first feeding pipe 5 and the second feeding pipe 11.

[0050] The specific implementation method is as follows: by setting a buffering and dispersing component 9, in the process of the landfill soil falling in the first discharge pipe 5 and the second discharge pipe 11, the fixed motor 906 drives the dispersion plate 902 to swing back and forth through the reciprocating screw 903, the screw seat 901, the bidirectional rack 904 and the transmission gear 905, so that the opening and closing postures between the two adjacent dispersion plates 902 change periodically, so that the falling landfill soil can be relatively dispersed when discharged, avoiding the accumulation of landfill soil and ensuring the uniformity of landfill. At the same time, the reciprocatingly swinging dispersion plate 902 can buffer and absorb the falling landfill soil to avoid the soil impacting the pipeline and causing damage to the pipeline.

[0051] The tamping assembly 7 includes a hollow scraper rod 702, which is rotatably connected to a connecting shaft inside the hollow scraper rod 702. Two symmetrically arranged connecting rings 705 are connected to the outer surface of the connecting shaft.

The two connecting rods 707 are connected to the same eccentric hammer 706 at one end away from the connecting ring 705. An auxiliary motor 704 is fixedly installed on one side of the hollow scraper rod 702. One end of the connecting shaft extends to the outside of the hollow scraper rod 702 and is connected to the output shaft of the auxiliary motor 704. Two symmetrically arranged electric push rods 701 are connected to the top of the hollow scraper rod 702. The two electric push rods 701 are connected to the same connecting cross bar 703 at one end away from the hollow scraper rod 702. The connecting cross bar 703 is arranged on one side of the main frame 1.

[0052] The specific implementation method is as follows: by setting a compaction component 7, the hollow scraper rod 702 scrapes and flattens the landfill material that has been filled in the groove, and the auxiliary motor 704 drives the eccentric hammer 706 to rotate through the connecting shaft, the connecting ring 705 and the connecting rod 707, and makes the hollow scraper rod 702 vibrate at a high frequency. While scraping and flattening the landfill material, it can also vibrate and compact the landfill material. On the one hand, the landfill material can be leveled and the flatness of the road surface can be improved. On the other hand, through vibration compaction, the compactness between the landfill materials can be improved and the gaps between the landfill materials can be reduced.

[0053] Working principle: When in use, the staff fixes the device to the traction equipment through the external connecting frame 2. After that, the staff drags one end of the pipe from the pipe reel 3 to the bottom of the laying traction wheel 10 and adjusts the height of the laying traction wheel 10. The auxiliary pipe enters the pre-dug trench. As the traction equipment moves, the main motor 408, the auxiliary motor 704, the drive motor 406 and the fixed motor 906 are started, and the external conveying device conveys the landfill soil into the main frame 1.

[0054] During this process, the driving motor 406 drives the active wheel 411 to rotate, and the active wheel 411 drives the driven wheel 405 to rotate through the first transmission belt 404, and the driven wheel 405 drives the pipe reel 3 to rotate, and realizes the orderly discharge of the pipe, and cooperates with the laying traction wheel 10 to realize the automated orderly laying of the pipe, the driving motor 406 drives the cam 412 to rotate, and the cam 412 drives the moving plate 413 to move, and the reset spring 417 drives the moving plate 413 to reset, so that the moving plate 413 performs reciprocating motion, and the moving plate 413 drives the sliding rod 416 to perform reciprocating motion, and the sliding rod 416 drives the vibrating block 415 to reciprocate and knock and vibrate the screen plate 407 back and forth, and the screen The plate 407 vibrates to screen the landfill soil on the screen plate 407, so that large pieces of soil remain above the screen plate 407 and smaller particles of soil fall below the screen plate 407. At the same time, the main motor 408 drives multiple discharge augers 403 to rotate through the transmission wheel 409 and the second transmission belt 410. The discharge augers 403 transport the large pieces of soil above the screen plate 407 to the first discharge pipe 5, while the smaller particles of soil are discharged through the second discharge pipe 11. Since the second discharge pipe 11 is arranged in front of the first discharge pipe, during landfill, the smaller particles of soil will enter the groove first, and the larger particles of soil will be laid on top of the smaller particles of soil, thereby realizing layered landfill of soil.

[0055] During the process of the landfill soil falling in the first discharge pipe 5 and the second discharge pipe 11, the fixed motor 906 drives the reciprocating screw 903 to rotate, the reciprocating screw 903 drives the screw seat 901 to reciprocate in the vertical direction, the screw seat 901 drives the bidirectional rack 904 to reciprocate, the bidirectional rack 904 drives the transmission gear 905 to rotate symmetrically, and the transmission gear 905 drives the dispersion plate 902 to swing back and forth, so that the opening and closing posture between the two adjacent dispersion plates 902 changes periodically, so that the falling landfill soil can be relatively dispersed when discharged, avoiding the accumulation of landfill soil.

[0056] After the paving is completed, as the external traction equipment moves, the hollow scraper rod 702 scrapes and flattens the landfill material that has been filled in the trench. During this process, the auxiliary motor 704 drives the connecting shaft to rotate, and the connecting shaft drives the connecting ring 705 to rotate. The connecting ring 705 drives the eccentric hammer 706 to rotate through the connecting rod 707. The eccentric rotation of the eccentric hammer 706 causes the hollow scraper rod 702 to vibrate at a high frequency. While scraping and flattening the landfill material, it can also vibrate and compact the landfill material.
