The invention relates to ra oad soil filling and compacting device, in particular to a road soil filling and compacting device. The technical problem of the invention is to provide a road clay fillingcompaction device capable of compacting the filled clay while transporting the clay for filling, crushing large pieces of clay, and facilitating flexible movement. A road soil filling and compactingdevice comprises a bottom plate, a mounting frame, a rotating shaft, a drum, a mounting seat, a box body, a discharging pipe, a shielding cover, a fixed pulley, a guide sleeve, a drawing rope, a drawing rod, a feeding hopper, etc. A mount bracket is uniformly connected with the front and rear sides of the bottom plate, a rotating shaft is connected with the corresponding mounting brackets of the front and rear sides, and a roller is connected with the rotating shaft. The invention preliminarily crushes the soil through the arranged crushing block, the toggle plate further crushes the soil while pulling out the soil, and the compaction plate can crush the soil laid on the road again while leveling the soil on the road, thereby facilitating the subsequent compaction work.
