Embodiment 1

[0025] Example 1: Please refer to Figure 1-5 , a tamping and compacting device for subgrade construction, comprising a horizontal fixed plate 1, a height adjustment seat 8 is fixedly connected to the upper right side of the horizontal fixed plate 1, and a rotating hinge 9 is fixedly connected to the top of the height adjusting seat 8, and the left side of the rotating hinge 9 The side is fixedly connected with a swing connecting rod 10, and the bottom of the swing connecting rod 10 is fixedly connected with a number of supporting push rods 11 at equal intervals. The left end of the swing connecting rod 10 is rotatably connected with a longitudinal transmission rod 12. Tamping shell 13, the inside of tamping shell 13 is slidably connected with tamping block 14, inside of tamping block 14 is fixedly connected with first spring 15, the other end of said first spring 15 is fixedly connected with the inner top of tamping shell 13, and the swing connecting rod 10 is driving Under t...

Embodiment 2

[0035] Embodiment 2: This embodiment is a further improvement of the previous embodiment: an engaging device 25 is fixedly connected between the limit slider 17 and the horizontal fixing plate 1 . The engaging device 25 includes a guide hole 251 opened on the outside of the limit slider 17, an engaging rod 252 is slidably connected to the inside of the guiding hole 251, and a second spring 253 is fixedly connected between the engaging rod 252 and the guide block 251. The inner side of the limiting chute 16 is provided with a plurality of arc-shaped locking holes 254 , and the arc-shaped locking holes 254 are matched with the outer ends of the engaging rods 252 . The outer end of the engaging rod 252 is hemispherical. The engaging device 25 enables the engaging rod 252 to cooperate with the arc-shaped locking hole 254 during the left and right movement of the limit slider 17 , and then the position of the limit slider 17 can be precisely adjusted to avoid inaccurate adjustment....

Abstract

The invention discloses a tamping and compacting device for roadbed construction, and belongs to tamping devices. The device comprises a horizontal fixing plate, and a height adjusting seat is fixedlyconnected to the right side above the horizontal fixing plate; the top of the height adjusting seat is fixedly connected with a rotary hinge; the left side of the rotating hinge is fixedly connectedwith a swing connecting rod; a plurality of supporting ejector rods are fixedly connected to the bottom of the swing connecting rod at equal intervals, a longitudinal transmission rod is rotationallyconnected to the left end of the swing connecting rod, a tamping shell is fixedly connected to the lower end of the longitudinal transmission rod, a tamping block is slidably connected to the inner side of the tamping shell, and a first spring is fixedly connected into the tamping block. When the tamping and compacting device is used, a motor rotates to drive an ejector block to jack up the supporting ejector rods, then the tamping block punches a subgrade under the action of gravity, the device can adjust the ejector block to be matched with different supporting ejector rods according to needs, and therefore adjustment of different jacking heights of the tamping block is achieved, adjustment of tamping force is further achieved, and the tamping and compacting device is wider in applicability.

Description

technical field [0001] The invention relates to a ramming device, in particular to a ramming and compacting device for roadbed construction. Background technique [0002] A tamping machine is a kind of machine used for tamping. It is a compaction machine that uses impact and impact vibration to tamp backfill soil layer by layer. It is mostly used for leveling and compacting the foundation during construction. [0003] For this reason, the Chinese patent (authorized announcement number: CN208152004U) discloses a roadbed construction tamping and compacting device, which discloses a roadbed construction tamping and compacting device, including a first support, the first support A support column is symmetrically fixedly connected to the lower surface, a second support is fixedly connected to an end of the support column away from the first support, a vertical plate is fixedly connected to the left end surface of the first support, and the vertical plate The side of the plate a...
