Perforating machine for water conservancy construction

The utility model discloses a perforating machine for water conservancy construction. The perforating machine comprises universal wheels, fixing screws, a rotating plate, a water tank, a fan, an air outlet frame, a water spraying frame, a drainage groove, a baffle, a partition plate, a supporting spring, a fixing buckle and a shovel-shaped bottom plate. After the positions and tracks of universal wheels, fixing screws and rotating plates are determined, the rotating plates abut against the universal wheel parts, so that the side faces of the universal wheels and the side face of the moving trolley stably run in parallel, and punching continuity and efficiency are improved; a drill bit after punching is cleaned and blow-dried through a water tank, a fan, an air outlet frame and a water spraying frame, and meanwhile waste water is recycled and discharged in a unified mode through a drainage groove and a baffle, so that environment pollution is avoided; drilled sundries are separated and recycled through the par
