Cross cutting machine for processing air-entrained concrete

The utility model relates to the technical field of cutting device for building material producing, in particular to a cross cutting machine for processing air-entrained concrete. Two symmetrically arranged lifting devices are arranged at the two sides of the machine frame, the lifting devices are movably sheathed on the guide arm of the machine frame and are driven by a hydraulic cylinder arranged on the machine frame, and a synchronizing shaft used for harmonizing the balance is arranged between the lifting devices at the two sides of the machine frame. The utility model accomplishes cutting with the lifting device lifting the blanks up, the chisel point components need no moving down, with the synchronizing shaft matching with the lifting devices at the two sides, the utility model can get blanks steady lifting and better cutting effect. Meanwhile, cutting time can be efficiently reduced, and the productivity can be efficiently increased.
