Reamer floating type two-stage vacuum brick extruding machine

The reamer floating type two-stage vacuum brick extruding machine comprises a machine frame and a base, the base is arranged at one end of the machine frame, an upper-stage extruding section is fixedly installed at the upper end of the machine frame, a lower-stage extruding section is fixedly installed on the base, a third reamer is arranged in a butt joint pipeline, and a second reamer is arranged in the butt joint pipeline. The floating shaft is elastically and movably arranged in the pipe shell through the first floating assembly, and the third reamer is elastically and movably installed in the butt joint pipeline through the second floating assembly. The floating type horizontal reamer and vertical reamer structure is adopted to eliminate the influence of additional axial force, the horizontal reamer and the vertical reamer are connected in a floating and synchronous mode, changes of all the reamers and space in the device have synergy, the material stirring paddle is arranged below the vertical reamer an
