Lunar soil deep drilling sample recycling mechanism

Abstract

The invention discloses a lunar soil deep drilling sample recycling mechanism. A wedge-shaped space is arranged along the circumference of a joint of a drilling machine and is internally provided with buckle rocking bars; racks are distributed in three layers from top to bottom, wherein the rack on the first layer is provided with a cylindrical boss, and three grooves matched with the buckle rocking bars are uniformly distributed along the circumference of the boss; the middle part of the rack on the second layer is clamped with a drill rod turntable case mechanism, and the arc middle part ofthe rack on the third layer is provided with round holes allowing drill rods to pass through along the circumference; a lifting motor is arranged at the middle part of the rack on the third layer andused for controlling the vertical movement of a slider base through a screw rod; one end of a guide rod is fixed on the rack on the third layer, and the other end of the guide rod is fixed on an upper round mechanical arm connecting plate; and the slider base is provided with a deep drilling motor for driving a motor and drill rod joint to rotate. In the invention, a plurality of short drill rodsare connected for deep soil sampling; the joint of the drilling machine can simultaneously finish buckling the racks of the drilling machine for drilling and clamping the turntable of the drilling machine for recycling, so that the mechanical structure is simplified; and the joints of the drill rods are in groove buckling connection conveniently, the transferring torque is large, and the connection is reliable.

Description

technical field [0001] The invention relates to a drilling rod sampling recovery mechanism, in particular to a lunar soil deep drilling sampling recovery mechanism. Background technique [0002] After entering the 1990s, many countries and organizations around the world, including China, began a new round of lunar exploration. Lunar soil sampling plays a decisive role in the analysis of lunar resource environment and future utilization. Considering the complexity and danger of astronauts landing on the moon, research on automatic sampling devices is currently the focus of research and development in various countries. [0003] In the field of outer space exploration, in order to study extraterrestrial bodies, it is necessary to send probes to them and collect samples to return to Earth for analysis. With the deepening of research, the requirements for sampling are also from the surface to the underground to obtain information such as soil layers. However, the detector is l...
