The utility model relates to the technical field of
road construction, and discloses a drilling device for roadbed compactness detection, which comprises a fixed seat, a positioning hole is arranged in the fixed seat, a fixed rod is fixedly connected onto the fixed seat, a mounting table is fixedly connected onto the fixed rod, a sliding cylinder sleeved on the fixed rod is arranged between the mounting table and the fixed seat, and a positioning hole is arranged in the sliding cylinder. A lifting plate is fixedly connected to the sliding
barrel, a material taking
barrel is fixedly connected into the lifting plate, a discharging port is formed in the top of the material taking
barrel, a driving shaft is rotationally connected into the material taking barrel, a spiral
drill bit is fixedly connected to one end of the driving shaft, and the bottom end of the spiral
drill bit penetrates through the material taking barrel to be arranged outside the material taking barrel. The equipment is driven by the two driving structures to
drill soil in a rotating mode and ascend and descend respectively, therefore, a worker can drive the equipment through the two hands respectively, no
external energy is needed, the equipment is easy to operate, convenient to use, high in drilling speed and good in
standardization, and the practicability of the equipment is improved.
