The invention relates to an experimental device for testing the point load strength of rock, in particular to a full-automatic rock point load test instrument. The full-automatic rock point load test instrument comprises a hydraulic jack, a movable hydraulic loading cone, a fixed loading cone, an electric hydraulic device and a measurement system, wherein a hydraulic cylinder of the hydraulic jack is communicated with the electric hydraulic device through a pressurization hydraulic pipe and a pressure-discharge hydraulic pipe; the movable hydraulic loading cone is fixed above a piston of the hydraulic jack; the fixed loading cone is fixed on a cross beam of a load bracket; the measurement system comprises an automatic measurement device, a liquid flow sensor and a hydraulic sensor; the liquid flow sensor and the hydraulic sensor are mounted in the pressurization hydraulic pipe in sequence. The full-automatic rock point load test instrument is improved in efficiency and safety, and realizes full-automatic load parameter measurement.
