Abstract

The invention relates to the technical field of drilling devices, and provides a drilling coring device with flexible drill bits. The device comprises a mounting seat, the drill bits mounted on the mounting seat in a manner of floating up and down and drilling tools hinged to the drill bits through hinge mechanisms. Therefore, the drilling tools can rotate between the folded positions where the drilling tools are folded inwards and the unfolded positions where the drilling tools are unfolded outwards, positioning mechanisms are arranged on the mounting seat, and can be matched with the drilling tools to limit rotation of the drilling tools when the drilling tools move to the unfolded positions. The actual working feed amount of the drilling tools can be adjusted by changing the positions of the drilling tools, so that the drilling coring device can cope with an unknown geological environment, and the coring efficiency is improved. Meanwhile, in the lifting process after coring is completed, the drilling tools rotate to the folded position, so that damage to a coring hole and the requirement for lifting force are reduced, the possibility of drill jamming is reduced, and the continuity of the coring process is improved.

Description

technical field [0001] The present application relates to the technical field of drilling devices, and more specifically, relates to a drilling and coring device with a flexible drill bit. Background technique [0002] In the prior art, in order to detect the geological conditions of extreme environments such as the moon and planets, drilling and coring them is an effective method. In drilling in extreme environments, human-assisted drilling is a difficult and costly option, so remote-controlled coring robots are often used for drilling and coring. The coring robot needs to monitor the environment in real time and implement different strategies in different environments to achieve the coring task and try to maintain the in-situ characteristics of the sample. The drill bit is the main working part in the drilling and coring process of the coring robot. The core components of the coring robot in the prior art include the drill bit and the drill bit, and the drill bit is usual...
