Impact type stone crushing device

The utility model relates to the technical field of constructional engineering, in particular to an impact type stone crushing device which comprises a stone crusher, an upper protection plate is movably installed at the upper end of the stone crusher, a side opening door is installed at the side end of the lower section of the stone crusher, and a linear push rod motor is fixedly installed in the stone crusher. A crushing table is fixedly mounted at the end of an output shaft of the linear push rod motor, and a first shovel plate is fixedly mounted on the inner wall of the stone crusher located above the crushing table. A good supporting effect can be achieved through the multiple lower supporting rods, when stones on the crushing table are impacted, the multiple lower supporting rods can improve the stability, a transmission rod can drive a connecting frame to move when moving, the connecting frame moves to drive first rubber sheets on the two sides to move, and therefore the stone crushing table is more st
