Compacting is a construction operation that uses heavy objects to make them fall freely repeatedly to tamp the foundation or filling soil and stone materials to improve their density. The existing application number is 202321137787.7, which is a ground compacting device, including a box body, a first motor is fixedly installed in the middle of the top of the box body, a driving gear is fixedly installed at the output end of the first motor, and a driven gear is movably engaged with the front and rear sides of the driving gear. A turntable is fixedly installed on the outside of the driven gear, and a connecting rod is rotatably connected to the outside of the turntable through a rotating member, and the bottom end of the connecting rod is movably connected to a sliding rod through a hinge, and the bottom end of the sliding rod passes through the box body and is fixedly connected to a connecting plate, and a compacting block is provided below the connecting plate. The first motor can drive the driving gear to rotate, the driving gear can drive the driven gear to rotate, and the driven gear can drive the turntable to rotate. The turntable can drive two compacting blocks to alternately compact the ground through the connecting rod and the sliding rod, thereby improving the compaction efficiency and ensuring the compaction effect of the ground. The ground compaction device has the following disadvantages: 1) the driving structure is complex and the cost is high; 2) the weight of the compaction block is fixed, which makes it difficult to meet the compaction requirements of different ground surfaces and has poor adaptability; 3) the overall weight is supported by moving wheels, which are easy to shift during the compaction process, resulting in poor stability and affecting the construction effect.
