AI Technical Summary
The existing soil compactor has a fixed counterweight water tank, which prevents the water inlet from facing downwards. Therefore, a drain pipe and valve must be installed at the bottom, which increases the manufacturing difficulty and cost.
The plastic water tank is mounted on a rotating surface, and the top water inlet pipe can be inverted. Water inlet and outlet are achieved through the same water inlet pipe, eliminating the need for a bottom drain pipe and valve, thus simplifying the manufacturing process.
The weight, manufacturing difficulty, and cost of the soil compactor have been reduced, while the ease of relocation and production costs have been improved.
