The invention relates to a portable mechanical acoustic frequency vibration sampling drill which comprises a base, an upright column, an acoustic frequency vibration device, a lifting device, a flexible transmission shaft and a power output device, wherein the upright column is fixed on the base; the upper end of the acoustic frequency vibration device is fixed at one end of a steel wire rope, the lower end of the acoustic frequency vibration device is connected with a drilling tool, and the other end of the steel wire rope goes around a pulley arranged at the top end of the upright column and is connected with the lifting device; the lifting device is fixed on the upright column; the power input end of the acoustic frequency vibration device is connected with the power output device through the flexible transmission shaft. According to the portable mechanical acoustic frequency vibration sampling drill, an eccentric mechanism is driven to generate acoustic frequency vibration and excitation force through purely mechanical transmission, namely the acoustic frequency vibration device is driven by the flexible transmission shaft, the acoustic frequency vibration device generates the vibration frequency and excitation force of up to 200 Hz, and the excitation force is transferred to the drilling tool, so as to realize the acoustic frequency vibration drilling of the drilling tool.
