[0025] Example:

[0026] Reference Figure 1-5 , a device for improving the compaction degree of the roadbed and the edge of an inspection well, comprises a circular ramming head 2 threadedly connected to a drill rod 1 on the top of the circular ramming head 2 and a rectangular ramming head 3 detachably mounted on the bottom of the circular ramming head 2, and also comprises: a clamping assembly, the clamping assembly comprises a plurality of sliders 5 slidably arranged in the rectangular ramming head 3, a shifting post 6 fixedly mounted on the top of the slider 5 and extending upward through the rectangular ramming head 3, wherein a slide groove and a moving groove communicating with each other are arranged inside the rectangular ramming head 3, the slider 5 is slidably arranged inside the slide groove, the shifting post 6 is slidably arranged inside the moving groove, and an elastic member is arranged between the slider 5 and the inner wall of the slide groove; an extrusion assembly, the extrusion assembly is arranged on the top of the rectangular ramming head 3, and is used to position the connected circular ramming head 2 and rectangular ramming head 3.

[0027] By installing the circular ramming head 2 on the arm of the excavator, it is convenient to tamp the foundation pit of a small area inside the alley. When the wall needs to be tamped, the rectangular ramming head 3 can be installed at the bottom of the circular ramming head 2. When the rectangular ramming head 3 needs to be used for work, the circular ramming head 2 is moved downward. When the circular ramming head 2 moves to the middle concave position of the rectangular ramming head 3, the circular ramming head 2 squeezes the sliding block 5 to move inside the slide groove. The elastic part is in a compressed state. The circular ramming head 2 continues to move downward until the circular ramming head 2 is completely fitted with the rectangular ramming head 3, the circular ramming head 2 no longer conflicts with the sliding block 5, and the elastic part is elastically reset. Push the slider 5 to rebound and reset. At this time, the slider 5 is against the upper surface of the circular ramming head 2, so that the circular ramming head 2 can be stuck in the groove on the top of the rectangular ramming head 3, and the installation of the two can be quickly completed, which is convenient for tamping the wall root. At this time, the circular ramming head 2 and the rectangular ramming head 3 in the tamping device can be squeezed and fixed through the set clamping assembly, so as to further improve the stability of the connection between the two. When it is necessary to remove the rectangular ramming head 3 from the circular ramming head 2 again, it is only necessary to push the lever 6 outward to drive the slider 5 to slide outward, so as to separate the circular ramming head 2 from the rectangular ramming head 3.

[0028] Specifically, the elastic member is a return spring 7, one end of which is connected to one end of the slider 5 located in the slide groove, and the other end of the return spring 7 is connected to the inner wall of the slide groove; when the slider 5 slides outward, the return spring 7 is compressed, and when the circular rammed earth head 2 and the rectangular rammed earth head 3 are engaged, the return spring 7 pushes the slider 5 to slide inward, and the slider 5 presses the circular rammed earth head 2.

[0029] Among them, the end of the slider 5 away from the return spring 7 is in a trapezoidal structure; the trapezoidal inclined surface of the slider 5 facilitates the slider 5 to slide into the inside of the slide groove when the circular ramming head 2 is pressed down.

[0030] In addition, a plurality of reinforcing ribs 4 are fixedly mounted on the circular rammed earth head 2 , which are used to strengthen the strength of the circular rammed earth head 2 and prevent the circular rammed earth head 2 from being damaged when the foundation is tamped.

[0031] Reference Figure 1-Figure 5 , a device for improving the compaction degree of the roadbed and the edge of the inspection well. Furthermore, the extrusion assembly includes a worm gear 14 rotatably installed on the rectangular ramming head 3, a pressure column 15 fixedly arranged on the end surfaces of both sides of the worm gear 14, a pressure block arranged at the end of the pressure column 15 away from the worm gear 14, and a driving assembly arranged inside the rectangular ramming head 3 for driving the worm gear 14 to rotate; an installation groove is opened inside the rectangular ramming head 3, and the driving assembly includes a turning handle 16 rotatably arranged on the side wall of the rectangular ramming head 3 and extending to the inside of the installation groove, and a worm 17 arranged at one end of the turning handle 16 located inside the installation groove and meshing with the worm gear 14.

[0032] After the rectangular ramming head 3 is installed at the bottom of the circular ramming head, the handle 16 is turned to drive the worm gear 14 to rotate through the worm 17. The worm gear 14 will drive the pressure column 17 to flip toward the circular ramming head 2 and drive the pressure block to be pressed tightly on the upper surface of the circular ramming head 2, so that the circular ramming head 2 and the rectangular ramming head 3 can be further squeezed and positioned to avoid shaking of the rectangular ramming head 3 and the circular ramming head 2 due to high-intensity vibration.

[0033] Reference Figure 1-Figure 5 , a device for improving the compaction of the roadbed and the edge of the inspection well. Furthermore, a buffer assembly is provided on the top of the drill rod 1, and the buffer assembly includes a fixed plate 8 fixedly installed on the top of the drill rod 1, a plurality of telescopic columns 10 slidably arranged on the fixed plate 8, a buffer spring 9 fixedly sleeved on the telescopic column 10, a limit block 11 fixedly installed at the bottom of the telescopic column 10, and a movable plate 12 fixedly arranged on the top of the telescopic column 10; a transmission shaft 13 is fixedly arranged on the movable plate 12, and the transmission shaft 13 is connected to the excavator mechanical arm.

[0034] When performing tamping work, the excavator drives the movable plate 12 to move downward through the transmission shaft 13, and the circular tamping head 2 and the drill rod 1 move downward at the same time. The circular tamping head 2 beats the foundation. At this time, the movable plate 12 compresses the buffer spring 9 to prevent the movable plate 12 from directly hitting the fixed plate 8; when the excavator drives the movable plate 12 to rise, the movable plate 12 drives the telescopic column 10 to rise, and drives the fixed plate 8 to rise through the limit block 11, and the fixed plate 8 drives the drill rod 1 and the circular tamping head 2 to rise. The buffer component is set to avoid direct contact and collision between the excavator and the drill rod 1 when tamping the foundation, which may cause damage to the equipment.

[0035] Specifically, the utility model is at work / in use: by installing the circular ramming head 2 on the arm of the excavator, it is convenient to tamp the foundation pit of a small area inside the alley, and when it is necessary to tamp the wall, the rectangular ramming head 3 can be installed at the bottom of the circular ramming head 2. When the rectangular ramming head 3 needs to be used for work, the turning handle 16 is first turned to drive the worm gear 14 to rotate through the worm gear 17, and the worm gear 14 drives the pressure column 15 to rotate upward, and the circular ramming head 2 moves downward. When the circular ramming head 2 moves to the middle recess of the rectangular ramming head 3, the circular ramming head 2 squeezes the sliding block 5 to move outward, and the reset spring 7 is in a compressed state, and the circular ramming head 2 continues to move downward until the circular ramming head 2 is completely fitted with the rectangular ramming head 3, and the circular ramming head 2 no longer conflicts with the sliding block 5. The reset spring 7 resets and pushes the sliding block 5 to slide inward, and the sliding block 5 is clamped with the circular ramming head 2, so that the circular ramming head 2 and the rectangular ramming head 3 are fixed, and then the worm gear 17 is rotated in the opposite direction. The worm gear 14 drives the pressure column 15 to rotate downward, and the pressure block contacts and presses the circular ramming head 2 to compact the circular ramming head 2, which is convenient for compacting the wall root; and when the rectangular ramming head 3 needs to be removed from the circular ramming head 2 again, it is only necessary to rotate the worm 17 by turning the handle 16 to drive the pressure column 15 to rotate upward, and then push the push column 6 outward to drive the slider 5 to slide outward, so that the circular ramming head 2 can be separated from the rectangular ramming head 3; and when compacting the earth, the excavator drives the movable plate 12 to move downward, and the circular ramming head 2 and the drill rod 1 move downward at the same time, and the circular ramming head 2 beats the foundation. At this time, the movable plate 12 compresses the buffer spring 9 to prevent the movable plate 12 from directly hitting the fixed plate 8. When the excavator drives the movable plate 12 to rise, the movable plate 12 drives the telescopic column 10 to rise, and drives the fixed plate 8 to rise through the limit block 11, and the fixed plate 8 drives the drill rod 1 and the circular ramming head 2 to rise, so as to avoid direct contact and collision between the excavator and the drill rod 1 when compacting the foundation, resulting in damage to the equipment.
