Abstract

The invention relates to a mechanical structure, and in particular to a digging device. The lunar soil digging device is installed on the end of a mechanical arm. A technical scheme is as below: the device includes a digging module (20), a vibration module (30) and a sealing module (40); the sealing module (40) is in fixed connection with the digging module (20); when a telescopic bucket (10) stretches into place, the digging bucket (6) rotates around a driving shaft (4) to form a closed structure with the telescopic bucket (10), so as to respectively realize the functions of lunar soil digging, sealing and setting-out. The device provided by the invention can cooperate with the mechanical arm through adjusting the included angle with the lunar soil surface to realize surface sampling of lunar soil in different depths. After digging, the sealing module (40) through linear motion to achieve sealing of the lunar soil. For setting-out, the vibration module (30) realizes percussion vibration on the housing to prompt smooth setting-out of the sample to the container.

Description

technical field [0001] The invention relates to a mechanical structure, in particular to a digging device. Background technique [0002] The lunar soil mining mechanism is installed at the end of the sampling robotic arm on the lunar surface, and follows the robotic arm to approach the surface of the moon. With the cooperation of the joints of the robotic arm, the mining and sealing of lunar soil is realized. At present, only the Apollo probe of the United States has landed on the moon, and the lunar soil is manually excavated. No robotic arm has yet been successfully launched to sample the lunar soil on the lunar surface. Contents of the invention [0003] The purpose of the present invention is to design a new type of lunar soil mining device, which can realize sampling and sealing of different depths of lunar soil under the cooperation of the rotation of each joint of the mechanical arm. [0004] The technical solution of the present invention is: lunar soil mining dev...
