Double-link extrusion type grouting pump

The utility model relates to a double-link extrusion type grouting pump, belonging to engineering grouting technology field is provided, including a pump shell. A transmission shaft is arranged in the pump shell along the axle wire; an extrusion roller which is parallel with the transmission shaft is connected with the transmission shaft by means of a rolling rack; the end of the transmission shaft drills through the pump shell and connects with a power take-off; an extrusion tube is arranged between the extrusion roller and the pump shell along the inner wall of the pump shell; an inlet and an outlet are respectively arranged at the upper and the lower part of the pump shell along the tangent direction; the two ends of the extrusion tube drill through respectively the inlet and the outlet of the pump shell; two groups of extrusion rollers and extrusion tubes which are parallel with each other are arranged in the pump shell. The utility resolves the difficult problems that one device can not grout two different slurry materials synchronously and can not carry out a construction at two different sites; moreover, the intermittent time of material feeding can be reduced by one time and the continuity of perfusion can be improved; in addition, the throughput is increased by one time.
