Abstract

The invention relates to an end sampler for planetary exploration, which relates to the end sampler for celestial body exploration. The end sampler for planetary exploration solves the problems that the conventional end sampler for planetary exploration cannot be directly connected with a mechanical arm, loses flexibility and mobility, and cannot meet the mass limit of a detector system due to large volume and heavy mass. In the end sampler of the invention, a first DC brushless motor(4) slows down by a planetary reducer(2) and then drives a worm screw(32) to rotate; two digging paws of a digging output device(B) are symmetrically arranged on both sides of the worm screw(32); worm wheels(31) are fixed on a rotary shaft(23) of the digging output device; the worm screw(32) is in meshed transmission with two worm wheels(31) on the digging output device(B); the worm wheels(31) drive the rotary shaft(23) of the digging output device to rotate; and the rotary shaft(23) of the digging output device drives a first bucket(25) and a second bucket(26) to rotate by a digging handle(22). The end sampler is applied to the technical field of detection of space resources.

Description

technical field [0001] The invention relates to an end sampler for planetary exploration, in particular to an end sampler for planetary exploration, and belongs to the technical field of space resource exploration. Background technique [0002] Planetary detectors detect the ore and space environment on the surface of the planet by landing on the surface of the planet or patrolling the surface of the planet. To analyze the ore and soil on the surface of the planet more accurately, an end sampler that can perform sampling operations flexibly is required. The end sampler is a mechanical system that directly acts on the control object and is the executive part of the detector. Its quality is directly related to the success or failure of the entire detection and sampling plan. At present, there are not many studies on the terminal sampler for planetary exploration. In China, it is mainly the principle prototype of the robotic sampler with the functions of multi-tube drilling, g...
