The present invention relates to a ground compacting device. According to the present invention, the ground compacting device included in a boom of an excavator and mounted on a hydraulic breaker including a chisel to compact a ground. The ground compacting device comprises: a chisel fixing part; a compacting plate; a plurality of reinforcing plates; and a coupling device. The chisel fixing part with a rectangular shape has a coupling hole formed on the center in a longitudinal direction to allow a lower part of the chisel to be coupled thereto. The chisel has a rectangular section and has a through hole formed on a lateral surface in a transverse direction. The compacting plate is coupled to a lower part of the chisel fixing part to compact the ground. Each reinforcing plate has a lower part welded to an upper surface of the compacting plate and one side surface welded to an outer circumferential surface of the chisel fixing part. The coupling device includes a bolt and a nut. The bolt passes through the through hole of the chisel and the coupling hole of the chisel fixing part to be fastened, and the nut is coupled to one end of the bolt. According to the present invention, the ground compacting device is mounted on a front end of the chisel of the hydraulic breaker mounted on the excavator through a comparatively simple work, thereby remarkably reducing the time taken for replacement. Moreover, the ground compacting device has a simple structure to reduce manufacturing costs, thereby reducing maintenance costs and increasing work efficiency. |
