Embodiment Construction

[0009] The ultrasonic excitation impact space sampling drill consists of four parts: an ultrasonic transducer (1), a pressurized clamping surface (2), a free mass (3) and a drill pipe (4). The position of the nodal surface of the ultrasonic transducer (1) is determined first, and then the pressurized clamping surface (2) is designed according to the position of the nodal surface. The ultrasonic transducer (1) is connected to the drill pipe (4) in a plug-in type, the free mass (3) is set on the drill pipe (4), and the pressurized clamping surface (2) is clamped on the test bench or manipulator. When the high-frequency AC excitation voltage is applied to the ultrasonic transducer (1), due to the inverse piezoelectric effect of piezoelectric ceramics, the ultrasonic transducer (1) produces longitudinal resonance, and the amplitude of the front end of the ultrasonic transducer (1) The rod amplifies the ultrasonic amplitude; the free mass (3) generates a high-frequency reciprocatin...

Abstract

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.

Description

technical field [0001] The invention relates to an ultrasonic excitation impact space sampling drill, which is suitable for unmanned space sampling and in-situ real-time analysis, and can also be used as a sampling device for pulverization sampling on the earth. Background technique [0002] With the development of space science and technology, people's exploration of science has extended to the outside world. However, in the process of detecting outer space planets in the future, it is necessary to study the original state of the planet. "Sampling" is one of the necessary basic links, but There is a huge difference between drilling samples in outer space and sampling and analyzing them on Earth. Restricted by various conditions, such as the carrying capacity and transportation volume of rockets and spacecraft, and the harsh environment outside the earth (high or low temperature, sunlight and radiation, low gravity, vacuum), etc., the design of the sampling device is limited...
