Claims

[Scope of utility model registration request]

Rotating shafts protrude in the width direction from both sides of the traveling vehicle, and the base ends of a pair of dirt removal plate mounting arms extending forward along both sides of the traveling vehicle are attached to the rotating shafts, A pair of perforated body mounting arms are connected to the discharging plate located at the tip of the upper discharging plate mounting arm, and extend toward the rear of the vehicle along both sides of the vehicle at the base end of the soil discharging plate mounting arm. integrally connect the base ends of the mounting arm, attach a drilling body for underdrain construction to the tip of the mounting arm, and further bend the axis of the drilling body mounting arm with respect to the axis of the earth removal plate mounting arm, and set the bending angle as follows. A work vehicle characterized in that the perforating body is located above the ground when the evacuation plate is in a horizontal position, and is located underground when it is tilted upward.
