Vibration penetrating lunar soil coring device with spiral assisted submersion

Abstract

The invention discloses a spiral assisted dive vibratory penetration type lunar soil coring device and belongs to the technical field of manual lunar surface sampling of manned space flight. The invention aims to solve the problems that the conventional lunar soil sampling device simultaneously realizes external spiral assisted dive and internal vibratory coring by virtue of a coring tube and thesampling capacity is low. The spiral assisted dive vibratory penetration type lunar soil coring device comprises a supporting mechanism, a vibratory coring mechanism, a spiral soil discharge mechanismand a sealing mechanism, wherein the supporting mechanism is used for providing a support frame for the vibratory coring mechanism and the spiral soil discharge mechanism; an electromagnetic exciteroutputs linear vibration, and the vibration is directly transferred to the coring tube by virtue of a vibratory ejector rod; an offset rotary drive motor transfers a rotary motion to a drill rod by virtue of a pair of gears, and the rotary motion path is positioned at the periphery of the vibration path; and the vibratory ejector rod, the coring tube and other vibratory coring parts penetrate through central axes of a low-speed shaft, the drill rod and other spiral soil discharge mechanisms, and the rotary motion path does not have reference to the vibration path. The device disclosed by the invention is used for collecting lunar soil samples.

Description

technical field [0001] The invention relates to a vibrating penetrating lunar soil coring device for spiral-assisted submersion, and belongs to the technical field of artificial sampling of the lunar surface in manned spaceflight. Background technique [0002] In the future spaceflight manned moon landing plan, astronauts need to manually collect samples of lunar soil under the lunar surface. The manual device for collecting lunar soil is required to be small in size, easy to operate, high in sampling efficiency, and maintain the bedding information of the primary lunar soil. it is good. [0003] The traditional lunar soil drilling method has strong penetration ability, but the drilling trajectory of the drill pipe is a helical line, and the sample lunar soil and the interior of the drill pipe produce severe friction, which reduces the sampling rate of the lunar soil and destroys the bedding information of the lunar soil; and The collection of lunar soil by direct hammer pe...
