The compaction hammer 18 compacts the ground, while the second spring rod 15 compresses the air inside the sleeve. This air compression and contraction causes the connecting rod to move, which in turn moves the scraper. The scraper removes the soil at the bottom of the compaction hammer. Because the scraper has a spring at its bottom, it can still move even when the compaction hammer moves downwards. The second spring rod also allows the compaction hammer to move even when it reaches the bottom of the sleeve. The piston plate's movement compresses and contracts the air inside the mounting box, which in turn blows and draws air from the air blowing pipe, the first suction pipe, and the second suction pipe, thus blowing off the soil on the side of the compaction hammer and absorbing dust.
