Novel TBM slag pump

The utility model provides a novel TBM slag pump which comprises a slag pump body connected with a heading machine hydraulic system and a stirring mechanism arranged on one side of the slag pump body. A high-pressure water opening connected with a water system of the heading machine is formed in the slag pumping pump body; and a flushing mechanism connected with a water system of the heading machine is matched with the stirring mechanism. Hydraulic driving is adopted, forward slag pumping and reverse flushing can be achieved, blockage of a material suction opening is avoided, the stirring mechanism and the flushing mechanism are arranged, deposited slag is secondarily stirred and suspended, pumping and discharging are facilitated, the operation efficiency is high, blockage is prevented, and torque is large; a TBM equipment hydraulic system can be utilized, extra space is not occupied, investment is reduced, the size is small, and moving is convenient; the influence of water gushing and slag deposition on equi
