Further, in the tamping device, under the driving state, the two hydraulic rods respectively extend to support the two support legs so that the far ends of the two support legs are kept in a state of not contacting the ground.

Has the advantages that: the tamping device adopts a light-weight rapid impact tamper, and the roller is designed into a hollow roller shape to reduce the dead weight, so the tamping device is not easy to collapse the road surface and can run on the road surface. The tamping device does not need a worker to hold the rapid impact tamper, and can reduce the working intensity of the worker. The bottom of the rammer is hemispherical, and even if part of the rammer is blocked by the bulge, other parts which are not blocked can also sink into the recess to tamp the recess.

Detailed Description

The invention will be described in further detail with reference to the following detailed description.

As shown in figure 1, a main roller 4 in the shape of a hollow roller is arranged at the bottom of the mounting plate 3, a mud guard riser 6 is arranged at the rear end of the mounting plate, and a solid cylindrical auxiliary roller 5 is arranged at the bottom of the mud guard riser 6. The front part of the mounting plate 3 is provided with a rapid impact rammer 1. The near ends of the two legs 7 (the other leg 7 is covered by the leg 7 in the figure) are respectively hinged on the rear wall surface of the fender vertical plate 6, and the far ends extend downwards in an inclined way without contacting the ground. One ends of the two hydraulic rods 8 are respectively arranged at two positions of the rear wall surface of the vertical fender 6, and the other ends of the two hydraulic rods 8 are respectively connected with the middle parts of the two support legs 7.

As shown in figure 2, the tamping device uses the main roller 4 and the auxiliary roller 5 as wheels, the tamping device stops when driving on the soil slope 9, the two hydraulic rods 8 are contracted to respectively pull the two supporting feet 7 to rotate clockwise around the hinged joint until the far ends of the two supporting feet 7 are supported on the soil slope 9, and then the tamping device is stopped. The rapid impact rammer 1 tamps a road surface of a road slope 9 by knocking the road surface through the rammer 2, the rammer 2 of the rapid impact rammer 1 is designed to be hemispherical, and the arc-shaped bottom surface of the rammer 2 can contact the slope surface to tamp the slope surface facing the slopes with different adaptive inclinations and different flatness. However, the rammer 2 with the hemispherical bottom surface also has the defects that the pressure born by the rammer 2 is very large due to the small contact area when the slope surface is rammed, and the requirement on the hardness of the rammer 2 is very high, so the ramming device is only allowed to be used on the road surface with low soil hardness. In addition, since the bottom surface of the rammer 2 is hemispherical rather than planar, the compacted road surface is not flat, and therefore, a roller is required to flatten the road surface.

After the tamping device tamps one part of the soil slope 9, the two hydraulic rods 8 extend out to prop up the two support legs 7 so that the two support legs 7 rotate anticlockwise around the hinged part until the far ends of the two support legs 7 leave the soil slope 9 and maintain the state of not contacting the ground, the main roller 4 and the auxiliary roller 5 run forwards along the soil slope 9 to flatten the ground just after tamping, because the headstock of the tamping device tilts on the slope, part of gravity of the quick impact tamper 1 can be converted into pressure of the two rollers on the soil slope 9, and the gravity of the quick impact tamper 1 can help the two rollers to flatten the just tamped road surface in the process of running to the next part to be tamped by the tamping device. The main roller 4 is generally solid and needs to be heavy enough to flatten the road surface, and the ramming device can design the main roller 4 into a hollow roller shape, so that the gravity of the rapid impact rammer 1 is reasonably utilized to help flatten the road surface which is just tamped, the problem that the main roller 4 of the hollow roller shape is not heavy enough is solved, the whole weight of the ramming device is reduced on the premise of flattening the road surface, and the ramming device is prevented from crushing the weak-support-force soil slope 9. The secondary roller 5 has a diameter of one third of the diameter of the primary roller 4, and is preferably designed to be solid since its weight is originally small and further reduction may not be enough to flatten the road surface.

The above description is only the embodiments of the present invention, and the scope of protection is not limited thereto. The person skilled in the art can make insubstantial changes or substitutions on the basis of the invention, and still fall within the scope of patent protection.
