A Multifunctional Integrated Soil Sample Recovery and Delivery Mechanism

Abstract

A multifunctional integrated soil sample recovery and transport mechanism comprises a drive gear (1), a time-delay movement mechanism (3), a feed transmission gear (4) and the like. The drive gear (1) is respectively engaged with the feed transmission gear (4) and a rotating gear (17). A guiding device (9) is fixed on a nut (10) on a lead screw (11), which is connected to the feed transmission gear (4) through the time-delay movement mechanism (3). An upper end of a transition connecting support (15) is connected to the rotating gear (17). A primary packaging container (13) is installed at the lower end of the transition connecting support (15) through a shear pin (19). A one-way shearing mechanism (16) is mounted at the middle section of the transition connecting support (15), and the lower end of the transition connecting support presses an upper end face of the primary packaging container (13). One end of a core lifting rope is connected to a core taking bag, and the other end of the core lifting rope passes through a through hole at the center of the guiding device (9) to be connected onto the primary packaging container (13). The mechanism of the invention is driven by a single motor, and has high system integration degree and high reliability.

Description

technical field [0001] The invention relates to a soil sample recovery and transmission mechanism. Background technique [0002] Drilling to obtain deep soil samples is the main sampling method in foreign space exploration. The unmanned autonomous detection method requires a complete set of complex actions in the whole process of soil sample drilling and recovery to be completed automatically. In foreign countries, the complex actions of sample recovery and transfer are generally completed by means of multi-degree-of-freedom robotic arms. [0003] After the drilling work of the soil drilling device is completed, the core bag (cylindrical, bendable) containing the soil sample needs to be pulled from the inside of the drill pipe to the top of the mechanism through the core rope, and the core bag is spirally wound on the annular primary packaging container Internally, the above process is called core lifting and shaping of the sample. After the shaping is completed, the primar...
