Description

Technical Field

[0001] The utility model relates to the technical field of rammers, in particular to a handheld lithium battery rammer. Background Art

[0002] The impact rammer is a compaction machine that uses impact and impact vibration to compact backfill soil in layers. It can be divided into electric impact rammer, gasoline impact rammer and vibration impact rammer. The electric impact rammer is driven by the motor through the reducer and crank connecting rod mechanism to make a rapid impact movement to compact the soil. When the rammer jumps off the ground, the operator can push the machine forward.

[0003] The patent document with announcement number CN214573866U discloses a handheld rammer for construction, including an impact mechanism, a casing, a rammer plate, a fixed seat, a rotating seat, and a rammer rod, wherein the impact mechanism is located at the rear side of the casing, the rammer rod is located below the casing, the rotating seat is located at the lower end of the rammer rod, the fixed seat is located outside the rotating seat, the rammer plate is located at the bottom of the fixed seat, and also includes a shock absorbing mechanism, wherein the shock absorbing mechanism includes a hand support, a shock absorbing spring, and a fixed frame, wherein the fixed frames are respectively installed in front of and on both sides of the casing, the shock absorbing spring is arranged on the inner side of the fixed frame, and the ends of the hand support are both located on the inner side of the fixed frame. The utility model utilizes the shock absorbing spring in the fixed frame to support the hand support, so that shock absorption can be performed when the rammer tamps the ground, thereby reducing the intensity of manual labor, but the prior art still has defects:

[0004] The rammer in the prior art controls the movement of the rammer by an operator holding a handrail with his hand. However, the position of the handrail on the rammer is fixed, so when operators of different heights use the same rammer, if the operator is tall, the operator needs to bend down to move the rammer, and if the operator is short, the operator needs to raise his hand to operate it. This is very uncomfortable to operate and reduces the applicability of the rammer. At the same time, the handrail of the rammer is mostly directly welded and fixed to the main body of the rammer, which causes the workers' hands to receive strong vibration shocks and easily fatigue after a long period of construction.
