Description

Technical Field

[0001] This utility model relates to the field of backfilling and compaction technology, specifically to an integrated machine for rapid backfilling and compaction of pile holes after the removal of underground obstacles. Background Technology

[0002] During construction, underground obstacles, such as old pile foundations, are often encountered. When these obstacles need to be removed, pile extraction is typically used. However, if the pile holes left after extraction are not properly treated in a timely manner, they can cause numerous adverse effects on subsequent construction, such as ground subsidence and affecting the stability of adjacent building foundations. Traditional pile hole backfilling and compaction work often requires multiple pieces of equipment working together. First, transport equipment is used to deliver the backfill material to the pile hole, and then compaction equipment is used to compact the material. This not only results in high equipment costs but also low construction efficiency, consuming a significant amount of manpower and time. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 This utility model provides a technical solution: a machine for rapid backfilling and compaction of pile holes after pile extraction for underground obstacles, including a connecting seat 1, a support frame 2 fixedly connected to the top of the connecting seat 1, a loading box 3 fixedly connected to one side of the top of the support frame 2 for loading soil, a hollow rod 11 slidably connected inside the connecting seat 1, a conveying pipe 5 fixedly connected to the bottom of the loading box 3, soil in the loading box 3 leaving the loading box 3 through the conveying pipe 5, a telescopic pipe 7 fixedly connected to the bottom of the conveying pipe 5, the telescopic pipe 7 and the conveying pipe 5 are internally connected, soil in the conveying pipe 5 enters the telescopic pipe 7, and the telescopic pipe 7 moves away from the conveying pipe. One end of 5 is fixedly connected to the hollow rod 11. The interior of the telescopic tube 7 is connected to the hollow rod 11. Soil in the telescopic tube 7 enters the hollow rod 11. The bottom of the hollow rod 11 passes through the bottom of the connecting seat 1 and is fixedly connected to the tamping plate 12. The hollow rod 11 moves, taking the tamping plate 12 with it to tampe the soil in the pile hole. A discharge port 13 is opened on one side of the tamping plate 12, which is connected to the interior of the hollow rod 11, so that the soil in the hollow rod 11 can enter the pile hole from the discharge port 13. A baffle 14 is symmetrically slidably connected inside the discharge port 13 to control the opening and closing of the discharge port 13.

[0026] Furthermore, a first connecting plate 15 is slidably connected inside the ramming plate 12. One end of the first connecting plate 15 is fixedly connected to the baffle 14. The first connecting plate 15 moves, causing the baffle 14 to move as well.

[0027] Furthermore, a turntable 16 is rotatably connected inside the ramming plate 12, and a connecting column 19 is fixedly connected to one side of the turntable 16. The rotation of the turntable 16 causes the connecting column 19 to rotate.

[0028] Furthermore, a second connecting plate 17 is fixedly connected inside the first connecting plate 15. The movement of the second connecting plate 17 moves the first connecting plate 15. An arc-shaped groove 18 penetrating the surface of the second connecting plate 17 is provided on one side. The outer side of the connecting column 19 is slidably connected to the arc-shaped groove 18. When the connecting column 19 moves along the arc-shaped groove 18, the second connecting plate 17 will not move. When the connecting column 19 rotates to the end of the arc-shaped groove 18, the connecting column 19 will rotate and move the second connecting plate 17. The second connecting plate 17 moves through the first connecting plate 15 and takes the baffle 14 out of the first connecting plate 15, allowing the soil to enter the pile hole.

[0029] Furthermore, a motor 20 is fixedly connected inside the ramming plate 12. The output end of the motor 20 is fixedly connected to the center of one side of the turntable 16. When the motor 20 is turned on, it drives the turntable 16 to rotate.

[0030] Furthermore, a movable plate 10 is fixedly connected to the outer side of the hollow rod 11, and the movable plate 10 moves the hollow rod 11 along with it.

[0031] Furthermore, a connecting frame 9 is symmetrically fixedly connected to the top of the connecting seat 1, and the two ends of the movable plate 10 are slidably connected to the outer side of the connecting frame 9. The movable plate 10 moves along the outer side of the connecting frame 9 to maintain the stability of the movable plate 10 during movement.

[0032] Furthermore, a cylinder 8 is fixedly connected to the top of the connecting frame 9. The output end of the cylinder 8 passes through one side of the connecting frame 9 and is fixedly connected to one side of the moving plate 10. After the cylinder 8 is turned on, it moves the moving plate 10.

[0033] Furthermore, the top of the loading box 3 is fixedly connected to an inlet 4, which allows for better loading of soil into the loading box 3.

[0034] Furthermore, a valve 6 is installed inside the conveying pipe 5 to control the opening and closing of the conveying pipe 5.

[0035] In use, place the device above the pile hole, open valve 6, and allow the soil in the loading box 3 to enter the hollow rod 11 through the conveying pipe 5 and the telescopic pipe 7. Then, turn on motor 20, which drives turntable 16 to rotate. Turntable 16 stabilizes and drives connecting column 19 to rotate. When connecting column 19 moves to one end of arc-shaped chute 18, it drives second connecting plate 17 to move through arc-shaped chute 18. The movement of second connecting plate 17 drives first connecting plate 15 to move. First connecting plate 15, along with baffle 14, moves away from the discharge port 13, allowing the soil in hollow rod 11 to enter the pile hole through discharge port 13. At the same time, turn on cylinder 8, which drives... The movable plate 10 moves along the outside of the connecting frame 9, and the movable plate 10 moves along with the hollow rod 11. The hollow rod 11 moves along with the tamping plate 12 to compact the soil in the pile hole. When the connecting column 19 rotates to the starting point of the second connecting plate 17, the arc-shaped chute 18 will move along the arc-shaped chute 18. At this time, the baffle 14 is located in the discharge port 13. With the cooperation of the arc-shaped chute 18 and the connecting column 19, the baffle 14 moves out of the discharge port 13 intermittently, so that the soil located directly below the discharge port 13 can also be compacted. The soil intermittently enters the pile hole, so that the soil that entered last time can be fully compacted by the tamping plate 12, making the soil more compact and increasing its firmness.
