Abstract

The invention belongs to the technical field of coring device processing, and specifically relates to a planetary multifunctional coring bit, a coring method and a coring system, aiming to solve the problem that the coring device cannot meet the collection of samples with different strengths; the coring bit includes a controller , primary coring assembly, secondary coring assembly and connecting plate; the primary coring assembly drills the sample area and drills the initial core based on the instructions sent by the controller; the secondary coring assembly For initial core drilling, the controller obtains the type of initial core based on the preset pressure value and the actual pressure value obtained by the pressure detection module set in the secondary coring component to formulate corresponding control instructions; if the actual pressure value is greater than the preset If the pressure value is set, the secondary coring assembly is controlled to return to the initial position, and the primary coring assembly is controlled to obtain the initial core; otherwise, the secondary coring assembly is controlled to collect sample cores according to the preset path; the present invention satisfies different intensity Coring of samples.

Description

technical field [0001] The invention belongs to the technical field of coring device processing, and in particular relates to a planetary multifunctional coring bit, a coring method and a coring system. Background technique [0002] The Perseverance rover will drill a hole in Jezero Crater on Mars in 2021, making its first attempt to collect rock and regolith samples on Mars. According to the returned data, the drill bit of the robotic arm of the Mars rover drilled to a depth of nearly 8 centimeters, and the drilling shape was intact, but the sample tube was empty. The reason for the failure was that the rock was not strong enough to collect core samples. The drill bit breaks the rock into fine pieces, leaving the pieces in the hole or in the debris pile. [0003] The second successful sampling of "Perseverance" is attributed to the change of the collected objects. The collected objects were large boulders on the ground, and the strength of the collected rocks was greatly ...
