AI Technical Summary
Technical Problem
The existing technology is inefficient and has safety problems when digging silt at the bottom of the lake. The excavator can only operate on the shore, with limited scope and high cost. It requires manual pushing and compacting of the soil during backfilling, which is inefficient.
Method used
A downward processing replacement support device is designed, including a cylinder, compaction structure, spiral blades, hydraulic cylinders and springs. The silt is excavated through the spiral blades, and the hydraulic cylinders and springs are used to compact and clean the soil.
Benefits of technology
The device can efficiently dig and consolidate silt, reduce human resource waste, improve work efficiency and reduce energy waste.

Abstract
The utility model relates to a lower processing replacement filling supporting device which comprises a cylinder body, a tamping structure is arranged outside the cylinder body, a spiral blade is fixedly installed on the outer surface of a rotating rod, a first through hole is formed in the rear side of the cylinder body, a baffle is arranged in a cavity, a fixing shell is fixedly installed on the rear side of the cylinder body, and a second through hole is formed in the rear side of the fixing shell. A spring is fixedly installed in the fixing shell, a guide rod is fixedly installed on the front side of the spring, and the tamping structure comprises a workbench, a feeding hole, a hydraulic cylinder, a sliding groove, a balancing weight, a sliding block and a second through hole. According to the lower treatment replacement filling supporting device, by arranging the tamping structure, after sludge at the bottom of the workbench is excavated through spiral blades, soil is input into two feeding holes and penetrates through two telescopic pipes to reach the bottom of a balancing weight, then two hydraulic cylinders are started, the two hydraulic cylinders press the balancing weight downwards, the soil is scattered and compacted, and the working efficiency is improved. Therefore, the function of tamping the soil is completed.
