Problems solved by technology

However, the in-situ detection of extraterrestrial celestial bodies faces difficulties such as complex surface samples, extreme environments, changing conditions, limited detector quality, unstable energy sources, and uncertain reliability.
With the increase of the hardness of the sampling samples, the increase of the drilling depth and the extreme deterioration of the detection environment, the difficulty of detecting extraterrestrial objects increases sharply.
It is difficult for general detection and sampling devices to meet the task requirements

Abstract

The invention provides an ultrasonic drilling sampling test platform. The center of the plane base on the platform is fixedly connected with a six-dimensional force sensor and a rock core fixture. The base of the platform is fixedly connected with a support frame. The strips are arranged in parallel with the dovetail-shaped guide rail groove, and there is a guide rail in the dovetail-shaped guide rail groove to cooperate with it. The guide rail is fixed on the motor bracket, and the motor and the ultrasonic drill are fixed on the motor bracket. The invention has the function of controlling the vertical drilling pressure, and also includes a gravity compensation device. It adopts the principle of high-frequency vibration to make brittle and hard rocks fatigue and break. It is necessary to test the average drilling pressure when different rocks are broken to guide the ultrasonic horn. , free mass unit, drill bit end face and other designs to improve drilling efficiency, the invention has drilling speed and power detection functions, and the corresponding drill mechanism parameters are designed to meet the maximum drilling rate of the same power.

Description

technical field [0001] The invention relates to the field of extraterrestrial celestial body detection and sample collection testing, in particular to an ultrasonic drilling sampling testing platform. Background technique [0002] The detection and sample collection of extraterrestrial celestial bodies has always been a research hotspot at home and abroad. However, in-situ detection of extraterrestrial celestial bodies faces difficulties such as complex surface samples, extreme environments, changing conditions, limited detector quality, unstable energy sources, and uncertain reliability. With the increase of the hardness of detection sampling samples, the increase of drilling depth and the extreme deterioration of the detection environment, the difficulty of detecting extraterrestrial objects increases suddenly. It is difficult for general detection and sampling devices to meet the task requirements. [0003] Based on the background of my country's Mars drilling sampling ...
