The invention relates to an ultrasonic excitation impact space sampling drill. The device mainly comprises an ultrasonic transducer, a pressurizing and clamping surface, a free mass and a drill rod. When a high-frequency AC excitation voltage is supplied to the ultrasonic transducer, the ultrasonic transducer generates longitudinal resonance due to the inverse piezoelectric effect of piezoelectric ceramics, and the variable-amplitude rod at the front end of the ultrasonic transducer amplifies ultrasonic amplitude. The free mass generates high-frequency reciprocating collision between the tail end of the clamped variable-amplitude rod and the drill rod under the excitation and vibration coupling actions of the ultrasonic transducer. The collision impact of the free mass and the vibration of the ultrasonic transducer are transferred to rock via the drill rod. When the impact strength is greater than the crushing strength of the rock, the rock is crushed. Compared with the ultrasonic space sampling drill without pressurizing cylinder surface thread connection, the ultrasonic excitation impact space sampling drill has high impact energy transfer rate, a corresponding axial force is applied according to rock hardness so as to improve the sampling drilling efficiency, and the drill has simple structure, light weight and low power consumption.
