[0042] Specifically, the working principle of the mixing and compacting device for the road solidification operation mechanism is as follows: when in use, the two connecting shafts 214 on the connecting seat 213 of the bracket 210 respectively rotate the connecting rods connected to the digging arm and the grab cylinder of the excavator, and the bracket 210 is controlled by the excavator to make the mixing head 240 extend into the soil and the compacting roller 260 press on the road surface, and the driving motor 230 receives hydraulic power from the excavator, starts the driving motor 230, and drives the main transmission shaft 222 to rotate, and the main transmission shaft 222 drives the adjacent transmission shaft 222 through the meshing of the linkage gear 224. The shaft 223 rotates, and the adjacent transmission shafts 223 are also driven to rotate by the meshing principle of the corresponding linkage gears 224. The main transmission shaft 222 and the transmission shaft 223 drive the mixing head 240 to rotate. The mixing and feeding system 100 supplies the two mixed curing agents for pavement curing to the spray pipe 250. The multiple mixing heads 240 mix the silt soil so that the soil is fully mixed with the curing agent, which effectively improves the pavement curing effect. The curing agent is directly mixed into the soil without penetrating into the soil, which effectively shortens the curing time. The pavement is then compacted by the compaction roller 260, and the compaction and mixing depth of the pavement curing operation mechanism using the mixing and compacting device can be adjusted by adjusting the excavator arm and grab cylinder of the excavator.

[0043] When the second curing agent supply part 132 and the first curing agent supply part 131 supply liquid, the supply pump 1311 is started, and the supply pump 1311 pumps out the curing agent in the storage box 120 through the feed pipeline 1312, and the pumped curing agent flows to the convergence pipeline 1315 through the discharge pipeline 1313 and the first check valve 1314, and the flow rate of the curing agent in the convergence pipeline 1315 is monitored by the flow meter 1316. The first check valve 1314 stops the liquid in the convergence pipeline 1315 from flowing back into the discharge pipeline 1313, and reduces the situation that the clean water flows into the discharge pipeline 1313 when the clean water supply part 133 supplies clean water. The convergence pipeline 1315 of the two curing agents is connected to the mixer 134 through a three-way pipe, so that the two curing agents flow into the mixer 134, and are mixed in the mixer 134 and supplied to the spray pipe 250. When the clean water supply part 133 supplies clean water, the water supply pump 1331 is started, and the water supply pump 1331 pumps out the clean water in the storage box 120 through the water inlet pipe 1332, and the pumped clean water flows to the dispersion pipe 1334 through the water outlet pipe 1333, and the first one-way valve 1314 on the dispersion pipe 1334 stops the liquid in the second curing agent supply part 132 and the first curing agent supply part 131 from flowing back into the water inlet pipe 1332, thereby reducing the occurrence of the curing agent flowing into the water outlet pipe 1333 when the second curing agent supply part 132 and the first curing agent supply part 131 supply the curing agent. The clean water flowing out of the dispersion pipeline 1334 flows into the converging pipeline 1315 of the second curing agent supply part 132 and the first curing agent supply part 131, flushing out the curing agent that can be mixed in the converging pipeline 1315, the mixer 134 and the spray pipe 250, and maintaining the residual curing agent in the converging pipeline 1315, the mixer 134 and the spray pipe 250, so as to facilitate the reuse of the mixing and feeding system 100.
