The invention belongs to the technical field of the foundation construction of drilled piles in the bridge engineering, and particularly relates to a drilling rig with a stone dragging function for the drilled pile construction. The drilling rig with the stone dragging function for the drilled pile construction solves the problem that the traditional drilled pile construction method has low construction progress in a rock-contained stratum. The drilling rig with the stone dragging function for the drilled pile construction comprises a stone storage system, a stone dragging system and a stone unloading system, wherein the stone storage system comprises a drilling bucket, an upper sealing plate and a lower sealing plate; the stone dragging system comprises a feeding stone guide cylinder and a stone dragging construction member; the stone unloading system comprises a stone unloading bin gate and a fore shaft steel plate; and a drilling system comprises a chambering tool bit. The drilling rig with the stone dragging function for the drilled pile construction has the beneficial effects that a new reverse circulation drilling mode is provided, and slags are discharged in two modes of the stone dragging system and the traditional reverse circulation; in a drilling process, larger stone blocks are extruded into the drilling rig, residual drilling slags are extracted out, time for breaking stone blocks in the drilling process is shortened, and the drilling efficiency is improved; and the drilling rig has the advantages of simple structure, convenience in manufacturing and wide applicability, and can be suitable for most soil texture stratums containing cobbles or stone blocks by connecting with various rotating reverse circulation drilling machines.
