Problems solved by technology

In addition, the unknown composition of asteroids makes drilling more difficult
Therefore, it is difficult to apply the traditional drilling sampling and digging sampling methods in the sampling robot, and it is necessary to develop a sampler with strong autonomy

Abstract

The invention provides a rotary motor and ultrasonic drill coaxial asteroid sampler. The sampler comprises a detector body, a telescopic mechanism, a sampling drill, an air blowing mechanism and a return cabin, the telescopic mechanism, the air blowing mechanism and the return cabin are all installed on the detector body, the sampling drill is arranged at the tail end of the telescopic mechanism,the air blowing mechanism is communicated with the sampling drill and the return cabin, and the telescopic mechanism drives the sampling drill to move up and down. According to the rotary motor and ultrasonic drill coaxial asteroid sampler, ultrasonic drilling with low bit pressure and high efficiency is adopted, asteroid surface sampling is achieved based on spiral drilling sampling, the rotary motor and the ultrasonic drill are coaxially arranged, and the structure is simple.

Description

technical field [0001] The invention belongs to the technical field of space resource detection, in particular to an asteroid sampler coaxial with a rotary motor and an ultrasonic drill. Background technique [0002] The geological evolution of asteroids is small and retains a lot of early information, which has far-reaching significance for the study of the origin of the solar system and the development of space resources. The most commonly used method for asteroid detection is to collect star soil for analysis. The probe must be attached to the surface of the asteroid or relatively fixed to it when sampling. However, the gravity on the surface of the asteroid is very small. If the probe is rigidly connected to the surface of the asteroid, the impact force generated during sampling will have a negative impact on the probe. If it is connected flexibly, the sampling equipment will be tested again. The sampling mechanism must adapt to its microgravity conditions, the sampling...
