A roadbed compactness detection device for road detection is technically characterized by comprising a
chassis body, a support and a sand filling
barrel body, the support and the sand filling
barrel body are detachably connected with the
chassis body, a drilling structure and a soil discharging structure are arranged on the support, the drilling structure comprises a drilling rod and a motor, and the drilling rod and the soil discharging structure are detachably connected. The motor drives the
drill rod to rotate, a soil outlet groove is formed in the position, close to the top, of the surface of the
drill rod, a soil inlet groove is formed in the bottom of the
drill rod, the soil discharging structure comprises soil discharging grooves and an inclined plate, the inclined plate is arranged on the outer side of the drill rod and located below the soil outlet groove, and the soil discharging grooves are formed in side plates on the two sides of the support. The soil discharging groove is located above the inclined plate, a disc hole is formed in the
chassis body, and the bottom of the drill rod penetrates through the disc hole. The utility model discloses a sand filling device, and aims to conveniently and quickly position a detection device at an original earth
cutting position to carry out sand filling operation after earth
cutting, conveniently
discharge soil during earth
cutting, reduce earth cutting processes and save time and labor.
