Indexable rotary impact ultrasonic drilling sampling air blowing sample delivery type asteroid sampler

Abstract

The invention provides an indexable rotary impact ultrasonic drilling sampling air blowing sample delivery type asteroid sampler. The sampler comprises a detector body, a footage mechanism, an indexing mechanism, a sampling drill, an air blowing mechanism and a return cabin, wherein the footage mechanism, the air blowing mechanism and the return cabin are all installed on the detector body, the indexing mechanism is arranged at the tail end of the footage mechanism, the sampling drill is arranged at the tail end of the indexing mechanism, the air blowing mechanism is communicated with the sampling drill and the return cabin, the footage mechanism drives the sampling drill to move up and down, and the indexing mechanism drives the sampling drill to rotate. According to the invention, a single piezoelectric stack is used as a unique power source, vibration on two sides of the piezoelectric stack is fully utilized, vibration on one side of the piezoelectric stack is converted into rotarymotion of a drill rod, vibration on the other side of the piezoelectric stack is converted into impact motion of the drill rod, and finally spiral drilling sampling of a rotary impact ultrasonic drillis achieved, the indexing mechanism is arranged in the sampler, the point selection sampling function on the surface of the asteroid is achieved, and the excellent shape adaptability is achieved.

Description

technical field [0001] The invention belongs to the technical field of space resource detection, and in particular relates to an indexable rotary impact ultrasonic drilling sampling gas blowing style asteroid sampler. Background technique [0002] Exploring asteroids has far-reaching significance for the study of the origin of the solar system and the development of space resources. In recent years, more and more foreign institutions have carried out asteroid sampling and return missions for asteroids. The surface of asteroids is mostly hard and exposed rocks, how to achieve efficient rock breaking is the primary difficulty. At the same time, due to the problem of microgravity on the surface of the asteroid, the trajectory of the broken rocks cannot be found, and how to collect samples has become another big problem. For this reason, various sampling methods emerge in endlessly, and the most typical one is the "touch and go" of the Japanese "Hayabusa". It uses the powerfu...
