Excess material recovery device for lathe machining

The invention discloses an excess material recycling device for lathe machining, and relates to the technical field of machine tool parts, the excess material recycling device for lathe machining comprises a lathe table top, a collecting box is embedded in the bottom of the lathe table top, a material collecting shell is installed at the lower end of a vertical blanking pipe, and a pair of crushing rollers driven by a driving mechanism to rotate is rotatably installed in the material collecting shell; a baffle penetrates through the vertical blanking pipe in a sliding mode, a through hole is formed in the baffle, and a sliding mechanism used for driving the baffle to slide in a reciprocating mode is arranged on the lathe table top. The baffle can be driven by the arranged sliding mechanism to transversely slide in a reciprocating mode relative to the vertical discharging pipe, through holes in the baffle and the vertical discharging pipe are intermittently overlapped, the intermittent falling and crushing eff
