The frog ramming machine is widely used for construction projects such as highways, buildings, water conservancy and the like; vibration impact compactors are used for building foundations and the like; the vibrating plate compactor is widely used in narrow places with small engineering amount. However, the impact piece of the existing ramming machine is also a supporting piece, so that an operator mainly plays roles in balancing and positioning, and the impact piece bears more vibration and vibrates more on the waist and shoulders. When the shoulder is compacted, the compactor needs to travel on the road surface, but the width of the road shoulder is usually 3-20 cm, one side of the road shoulder is the road surface, the other side of the road shoulder is the land area or the guardrail for greening, and the narrower road shoulder cannot be used as a supporting surface for the small-sized compactor to travel. The traditional tamper is not suitable for continuous tamping operation on long-distance shoulders due to the fact that labor is consumed, part of the shoulders are higher, and the operation difficulty of an operator for operating the tamper is further improved due to the fact that the shoulder supporting surface is smaller.
