The invention provides a split Hopkinson rock impact test device, which comprises an incident solid rod, wherein the incident solid rod is provided with an incident end impacted end; an output rod collinear with the axis of the incident solid rod, wherein a rock sample is arranged between the output rod and the incident solid rod; a conical bullet comprising a diameter expanding section, wherein the diameter of the large-diameter end of the diameter expanding section is twice that of the small-diameter end of the diameter expanding section. In a test, the conical bullet is shot into the axial cavity part of the incident solid rod from the shot end of the incident end in a posture that the small-diameter end is in front. The diameter of the large-diameter end of the expanding section of the conical bullet is twice that of the small-diameter end, and the end face of the small-diameter end is prevented from being torn while the waveform meets the requirement. 本申请提供了一种分离式霍普金森岩石冲击试验装置，分离式霍普金森岩石冲击试验装置包括入射实心杆，所述入射实心
