Hydraulic splitting machine and ultrahigh pressure hydraulic system thereof

The invention relates to the technical field of cleaving machines, and discloses a hydraulic cleaving machine and an ultrahigh-pressure hydraulic system thereof. Two pressure cylinders are connected with a hydraulic oil cylinder, a hydraulic piston rod of the hydraulic oil cylinder extends out through electrical action of an electromagnetic valve and acts on a cleaving sleeve through a wedge block, the cleaving sleeve is expanded, and large enough cleaving force is output; therefore, the stone is cracked; when the splitting sleeve is separated from the original splitting hole, the electromagnetic valve loses power, hydraulic oil of the hydraulic rodless cavity returns to an oil tank of the oil supply system, and the hydraulic piston rod retracts to drive the wedge block to move until the splitting sleeve is shrunk to the minimum size; high pressure is transmitted through the pressure cylinder, the splitting machine can generate huge stress in rock or concrete, and therefore efficient and rapid splitting is ac
