AI Technical Summary
Technical Problem
Existing hollow box-type retaining wall filling technology is cumbersome to operate, inefficient, and the material is unevenly piled up, requiring manual assistance.
Method used
The combination of a screw feeder and a packing assembly is adopted. The screw feeder is set at an incline, and the packing assembly drives the packing cylinder to reciprocate above the empty box unit through a drive component. Combined with limit switch control, the material is evenly distributed.
Benefits of technology
It improves the filling efficiency of empty unit, avoids material accumulation, simplifies the operation process, and improves the uniformity and automation of filling.

Abstract
The utility model relates to the technical field of retaining wall construction equipment, in particular to a filling device for construction of an empty box type retaining wall. The filling device for construction of the empty box type retaining wall comprises a spiral feeder, a filling assembly and a first supporting rod. A mounting rod is mounted on the first supporting rod, a discharging opening is formed in the spiral feeder, and the end, provided with the discharging opening, of the spiral feeder is supported through the first supporting rod. The packing assembly comprises a packing barrel and a driving part, the packing barrel is slidably mounted on the mounting rod, and the driving part is connected with the packing barrel. The filler cylinder is provided with a discharge port, and the moving distance of the discharge port in the axial direction of the mounting rod is smaller than the length of the empty box unit in the axial direction of the mounting rod. Through mutual cooperation of the spiral feeding machine and the filling assembly, materials can be evenly scattered into the empty box units, the problem that in the prior art, due to filling material accumulation, the accumulated materials need to be subjected to follow-up treatment manually can be solved, and the filling efficiency of the empty box units of the retaining wall is improved.
