Above-mentioned technical proposal is used, the utility model has advantageous effect below：

1, according to the width of ditch, the relative distance between two firming components is adjusted by regulating device, so that institute The ridge that packer is suitable for pressing the ditch of different in width is stated, it is convenient and efficient, resource is also saved, and the utility model can be to ditch two The ridge on side is carried out at the same time firming operation；

2, the utility model is by pressing the ridge ridges Jian Ya, and presses ridge side by flanging part simultaneously, both ensure that the effect on pressure ridge, It prevents the phenomenon that ridge caves in occur during pressing ridge again, is also prevented from soil and falls into ditch.

Description of the drawings

Fig. 1 is the structural schematic diagram of the packer of the utility model.

Specific implementation mode

In order to make the content of the utility model be easier to be clearly understood, below according to specific embodiment and combine attached Figure, is described in further detail the utility model.

As shown in Figure 1, a kind of packer, it includes：

Main shaft 1；

Two groups of firming components, two groups of firming components are connected to along the axial direction of main shaft 1 on main shaft 1；

Two regulating devices are respectively set there are one regulating device between every group of firming component and main shaft 1, are adjusted with will pass through At least one regulating device is saved to adjust the relative distance between two groups of firming components, and then by firming component to ditch both sides Ridge is carried out at the same time firming operation.

As shown in Figure 1, the firming component includes the pressure ridge part 2 being connected with each other and flanging part 3, pressure ridge part 2 and pressure Edge pieces 3 is sleeved on main shaft 1, and the pressure ridge part 2, close to the end of main shaft 1, the flanging part 3 is close to the centre of main shaft 1 Position, the regulating device are arranged between flanging part 3 and main shaft 1.

As shown in Figure 1, it is characterised in that pressure ridge part 2 is cylindrical.

As shown in Figure 1, the flanging part 3 includes inner cylinder 31 and outer barrel 32, the inner cylinder 31 is sleeved on main shaft 1, described Outer barrel 32 is sleeved on the outside of inner cylinder 31, and the outer barrel 32 is connected with inner cylinder 31, and the outer barrel 32 is in a circular table shape, described outer The small end face of cylinder 32 is connected with pressure ridge part 2, and the size one of the small end face of the outer barrel 32 and the end face of pressure ridge part 2 It causes, the regulating device is arranged between inner cylinder 31 and main shaft 1.
